DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a juicer for squeezing juice from vegetables, fruits, etc. at home.

(Prior art) Regarding this type of conventional regulator,
This will be explained with reference to FIG. 11, taking Publication No. 25598 as an example.

In the same figure, the conventional juicer has a main body 1,
It consists of a container 2 mounted on a main body 1 and a lid 3 thereof. Fixed plates 4 having engaging hooks 4a at their upper ends are rotatably attached to both outer sides of the main body 1 so that the left and right sides can be interlocked, and each engaging hook 4a is attached to the lid 3. It has a structure in which the container 2 and the lid 3 mounted on the main body 1 are fixed to the main body 1 by engaging with the engaging protrusions 3a formed on both sides of the lower end.

(Problems to be Solved by the Invention) However, in the above configuration, after the container 2 and the lid 3 are placed on the main body 1, the fixing plate 4 is operated and the engaging hook portion 4a is attached to the lid 3. It is necessary to engage the engaging protrusion 3a, and two operations are required: placing the container 2 on and closing the lid 3, and operating the fixing plate 4 to fix the lid 3, and also removing the container 2. At the same time, two operations were required: removing the fixing plate 4 and lowering the container 2, which caused the problem that the operation was complicated and troublesome.

Furthermore, since the fixing plate 4 is provided on the outside of the main body 1, the width becomes wide and the appearance becomes complicated, making it difficult to miniaturize.

The present invention solves the above-mentioned problems and provides a compact juicer with a simple appearance, in which the container and lid can be attached and detached in one operation.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides engaging holes in the extension parts of the lower ends of both sides of the lid, and protrudes from both sides of the main body, and provides the above-mentioned A built-in clamp is always biased in both directions by a spring, and has an engaging protrusion that fits into the engaging hole of the clamp.
Further, the protruding surface of the engagement projection forms an obliquely upward cam surface. In addition, the above-mentioned clamp is provided with an inclined rib with a low lower part on the inner wall side of the main body, and a guide rib that extends in the vertical direction opposite to the above-mentioned inclined rib on the inner wall of the main body, and furthermore, the above-mentioned inclined rib and guide rib are provided In between, there is provided an operating plate that can be moved up and down freely by external operation.

(Function) With the above configuration, when the container and lid are sequentially mounted on the main body and the lid is pressed down, the extension of the lid hits the cam surface of the engagement protrusion of the clamp, and as it slides down the cam surface, Push the engaging protrusion inward against the spring. Furthermore, press down on the lid to open the locking hole.
When the clamp matches the engagement protrusion, the clamp is urged outward by the spring, so the engagement protrusion fits into the engagement hole, and the lid is fixed to the main body.

When the actuating plate is pushed up by operating it from the outside, the actuating plate moves up the inclined rib of the clamp and pushes the clamp inward against the biasing force of the spring.
The engaging protrusion comes out of the locking hole of the inner lid. At this time, the guide ribs on the inner wall of the main body support the actuating plate from the back side, reduce frictional resistance, and facilitate operation.

(Example) An example of the present invention will be described with reference to FIGS. 1 to 10.

FIG. 1 is a sectional view of a regulator according to the present invention. The regulator includes a main body 1 to which an electric motor 8 is mounted via a buffer body 7 using a bottom plate 5 and screws 6, and an output connected to the rotating shaft of the electric motor 8.

Note that a plurality of legs 5a are formed on the bottom surface of the bottom plate 5. Further, in the material input port 3b of the lid 3, there is a push rod 13 for pressing loaded vegetables, fruits, etc. onto the cutter 10.
They are slidably fitted. Further, as shown in the perspective view of FIG. 2, the container 2 is provided with a juice outlet 2a at one corner of the bottom, and a third
As shown in the bottom view of the figure, a leaf spring 14 is installed in rectangular spring housing recesses 2b formed on both sides.

Returning to FIG. 1, there are containers 2 on both sides of the upper part of the main body 1.
The protrusion 1 that the leaf spring 14 comes into contact with when placed on the
a is provided, and when the lid 3 is fixed to the main body 1, the protrusion 1a is in a state in which the plate spring 14 is bent, as shown in FIG.

As shown in FIG. 2, the lid 3 has downwardly extending portions 3c formed on both sides, and an engagement hole 3d provided at the tip thereof.

As shown in FIG. 1, the main body 1 has clamps 16 on both sides thereof that are biased outwardly by compression coil springs 15 and are supported by fixing anvils 5b formed on the bottom surface of the bottom plate 5. Has been installed. The upper end of the clamp 16 protrudes from the main body 1 and fits into the engagement hole 3d of the lid 3 described above.
Engagement protrusion 16a having a cam surface whose upper surface faces upward
and an inclined rib 16b having a lower lower part is formed at the upper part of the inner wall side of the main body. Further, a guide rib 1b extending in the vertical direction is formed on the inner wall surface of the main body 1 so as to face the above-described inclined rib 16b. An operating arm 17 is disposed between the clamp 16 and the guide rib 1b.

5 and 6 are perspective views and side sectional views showing the relationship between the clamp 16 and the actuating arm 17. The support shaft 20 is rotatably supported by a support shaft 20 fixed with a screw 19, and biased counterclockwise by a compression coil spring 21. Note that the actuating arm 17 is held in a substantially horizontal steady position by the main body 1, the operating knob 18, and the compression coil spring 21.

Returning to FIG. 2, the operating arm 17 is located on the left front of the main body 1.
The operation knob 18 and the engagement protrusion 16a of the clamp 16 protrude from the side surface of the upper seal portion.

The operation of the juicer having such a configuration will be explained. First, as shown in Figure 1, the main body 1
After placing the container 2 thereon, the centrifugal separation cage 11 equipped with the comb-shaped filter 12 is fitted onto the output shaft 9.

Next, the lid 3 is fitted to the inner periphery of the container 2, and the extension part 3c is fitted to both sides of the main body 1, so that the tip of the extension part 3c is inserted into the main body 1. It hits the inclined cam surface of the engagement protrusion 16a protruding from 1. Subsequently, when the lid 3 is pushed down, the extension part 3c pushes the engagement protrusion 16a to the surface of the main body 1 against the biasing force of the compression coil spring 15, rides on this, and at the same time, as shown in FIG. , the leaf spring 14 of the container 2 is supported by the protrusion 1a of the main body 1. When the lid 3 is subsequently pushed down, the leaf spring 14 is bent and the container 2 is pushed down, and at the same time the extension 3c is lowered and the engagement hole 3 is lowered.
When d coincides with the engagement protrusion 16a, the engagement protrusion 16a is depressed by the biasing force of the compression coil spring 15, resulting in the state shown in FIG. 1, and the lid 3 is fixed to the main body 1.

In this way, the lid 3 can be fixed to the main body 1 by attaching the lid 3 to the main body 1 and pushing it down. At this time, the leaf spring 14 housed in the container 2 is bent by the protrusion 1a of the main body 1, and an upward biasing force is generated.

Next, when removing the lid 3, push down the operating knob 18 provided at the front of the main body 1, and as shown in FIG.
While compressing the actuating arm 1, the actuating arm 1 rotates counterclockwise about the support shaft 20 as a fulcrum, as shown in FIG.
7 is pushed between the inclined rib 16b of the clamp 16 and the guide rib 1b of the main body 1, and the clamp 16 is pushed against the biasing force of the compression coil spring 15.
It is tilted inward using the fixing anvil 5b of the bottom plate 5 as a fulcrum. According to the movement of the clamp 16, the engaging protrusion 1
When the container 6a is pulled in and removed from the engagement hole 3d of the lid 3, the container 2 and the lid 3, which are biased upward by the leaf spring 14, are lifted from the main body 1. Even if you release your hand from the operation knob 18 in this state, the engagement protrusion 1
Since 6a is not fitted into the engagement hole 3d, the lid 3 can be easily removed.

Note that when the actuating arm 17 moves upward along the inclined rib 16b, the actuating arm 17 moves upward along the inclined rib 16b.
receives the pressure of the compression coil spring 15 through the
As shown in FIG. 10, the actuating arm 1 is supported by the guide rib 1b opposite to the inclined rib 16b.
7 is not displaced outwardly, and the clamp 1
6 is accurately displaced by a distance corresponding to the height of the inclined rib 16b. Furthermore, since the actuating arm 17 slides in line contact with the guide rib 1b, the contact resistance is small and it can be moved smoothly.

Furthermore, since the clamp 16 is built into the main body 1 and fixes the lid 3 from the inside, there are fewer parts that protrude to the outside of the main body 1, and the size of the parts can be reduced.This not only makes the Jusa smaller, but also saves storage space. It also requires less. Moreover, since there are no parts that protrude outward, there is no chance of accidents such as catching clothes etc. during use.

(Effects of the Invention) As explained above, according to the present invention, the lid is provided with an engagement hole in its extension, and the body protrudes from the body and fits into the engagement hole to lock the lid. a clamp biased outwardly by a spring is arranged; furthermore, the above-mentioned clamp has a sloped rib with a low downward slope on the inner wall side of the main body, and the inner wall of the main body faces the above-mentioned sloped rib. Between the above-mentioned inclined ribs and guide ribs, there is an operating arm that has an operating knob that projects forward of the main body and is rotatably supported on the main body. By attaching it to the main body and pushing down further, the lid can be fixed to the main body with one action.Furthermore, by pushing down the operating knob, the operating arm rides on the inclined rib and the engaging protrusion is pulled out from the engaging hole of the lid. It can be removed from the main body.

In addition, a small-sized lever with a beautiful appearance and no fixing plate on the outside can be obtained. Furthermore, since there are no parts that protrude to the outside, there is no danger of catching clothes or the like, making the jacket excellent in operability.
