Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a locking device for a moving member that is incorporated into a substrate formed by integrally molding a resin onto a metal plate (hereinafter referred to as outsert molding).

Structure of a conventional example and its problems FIGS. 1A and 1B show a locking device used in a conventional digital audio player during transportation. In FIGS. 1A and 1B, 1 is an optical pickup, 1a is a protruding piece thereof, 2 is a base into which the optical pickup 1 is installed, 3 is a guide shaft that supports the optical pickup 1, 4 is a housing, and 5 is a housing for transportation. A locking material 6 inserted into the elongated hole 4a of the body 4 is movably held by the arms 4b, 4b of the housing 4, and has a screw 6a at its tip, and 7 is a spring.

The operation of the conventional lock device constructed as described above will be explained below.

In FIG. 1A, during transportation, a locking material 5 is inserted from the outside of the casing 4 through a long hole 4a made in the casing 4, and is fixed between the optical pick-up 10 and its protruding piece 1a. 10 is fixed and released by pulling out the locking material 5 from the elongated hole 4a. In addition, in FIG. 1B, a locking material 6 having a screw 6a machined at the tip thereof is rotated from outside the housing 4 with a screwdriver, etc., and the screw 6a is tightened to a part of the optical pickup 10, thereby opening the optical pickup 1. is fixed and released by loosening the locking member 6 and removing it from the optical pickup 1 by the force of the spring 7.

However, in such a conventional configuration, the locking members 5, 6 and the spring 7 are separate parts, increasing the number of parts, and in the example shown in FIG. It was difficult to store parts until they were locked during transportation, and there was a problem that parts could be lost.

Purpose of the Invention The present invention is intended to solve these conventional problems, and to provide a lock device that does not require an increase in the number of parts and eliminates problems such as loss by building the parts into the device. The purpose is to

Structure of the Invention The present invention uses a base plate in which a resin is outsert molded on a metal plate as a base for incorporating parts to be locked, and a clamp member which is outsert molded so that one end becomes a free end is also outsert molded. By rotating the locked lock member,
The clamp member is swung out around a certain fulcrum and the parts to be locked are clamped and locked. By using only outsert-molded members on the same metal plate, there is no increase in the number of parts during transportation. It is designed so that the lock can be performed.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. 2 to 6.

In FIGS. 2 to 6, parts having the same functions as those in FIG. 1 are denoted by the same reference numerals, and explanations thereof will be omitted. 8 is a metal plate substrate, 9 is a clamp member that is outsert-molded on the substrate 8, 10 is a lock member that is also outsert-molded on the substrate 8, and the third
As shown in Figures A and B, it is integrated with the boss 11 on the back surface through a circular hole in the substrate 8. Lock member 1
0 and the center of the boss 11 are offset, and the lock member 10 and the boss 11 constitute an eccentric shaft. Further, the tip of the boss 11 has a slot in the shape of a Phillips-head, so that it can be hit with a screwdriver. Then, as shown in FIG.
A part of the distal end thereof extends to the vicinity of the housing 4 to form a protrusion 12 . Further, in order to make the protrusion 12 more visible, a small hemispherical protrusion 13 is provided at the tip of the protrusion 12. As shown in FIG. 6, the words "Lock" and "Free" and arrows 14 are engraved on the outside of the housing 4 at positions corresponding to the protrusions 12.

The operation of the locking device of this embodiment constructed as described above will be explained below.

First, from the state shown in FIG. 3A, the boss 11 is rotated using a screwdriver. Then, the locking member 10 is swung by the eccentricity with respect to the boss 11, and the clamping member 9 is moved to a position where the optical pickup 1 is sandwiched, as shown in FIG. A stopper (not shown) is attached to the boss 11 side of the board 8, and the boss 11 is prevented from rotating beyond this position.
The optical pickup 1 is locked at this position. To release the lock, rotate the boss 11 in the opposite direction. Then, the lock member 10 returns to its original position, and the clamp member 9 returns to its original position by its own elasticity, releasing the lock. At this time, in case the clamp member 9 does not return completely by its own elasticity, a part of the clamp member 9 is extended, and the clamp member 9 is forcibly returned by the outer periphery of the lock member 10 that has been rotated to the release position. In addition, a return member 9a is added to a part of the clamp member 9.

In addition, in order to be able to determine from the outside whether the current state is a locked state or a free state, a part of the tip of the boss 11 is extended as shown in FIG.
It would be even more convenient if the outside of the housing 4 was engraved with "Lock" and "Free" in correspondence with the protrusions 12, as shown in FIG. In the example of Fig. 6, the protrusion 12 is at "Lock", so
This shows that the optical pickup 1 is currently in a locked state. When the lock is released, the protrusion 12
Needless to say, it comes under the stamp "Free".

By doing the above, there is no need to prepare the locking members 5, 6, spring 7, etc. as separate parts as shown in Fig. 1, and it is possible to obtain a hilt-in locking device without increasing the number of parts. can.

Effects of the Invention The present invention incorporates parts to be locked into an outsert-molded board, and provides a clamp member on the board by outsert-molding, thereby achieving an excellent built-in method without increasing the number of parts. This realizes a new locking device.
