Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a connection structure of the clamps in a set of two connection clamps used to connect the construction pipes when, for example, constructing a temporary scaffold at a construction site.
[0002]
[Prior art and problems to be solved by the invention]
A set of two connected clamps that connect the clamps to clamp and hold the pipe so that the clamps are fixedly connected, and the other clamp rotates freely with respect to one clamp. Although the thing etc. which were pivotally connected are used, what can be fixedly connected by rotating and adjusting the rotation angle of the other clamp with respect to one clamp according to a use is also used.
[0003]
This is because, for example, when connecting pipes arranged in parallel or when connecting pipes orthogonal to each other, the other clamp is rotated 90 degrees with respect to one clamp. Therefore, in any case, it can be used as a fixed connection type clamp.
[0004]
Various adjustment and connection mechanisms that can adjust the relative rotation angle of the conventional clamp have been proposed. However, the adjustment operation is troublesome and the structure is complicated. Therefore, the production is troublesome, and it is not possible to solve all the problems such as inferior mass productivity, increased production cost, and insufficient adjustment fixing strength.
[0005]
The present invention provides an epoch-making clamp connection structure which is superior to any of the above-mentioned problems as compared with conventional adjustment fixing connection mechanisms and is extremely practical.

[0015]
【Example】
Specific embodiments of the present invention will be described with reference to the drawings.
[0016]
In the present embodiment, a clamp body 1 is configured by pivotally attaching a proximal end of a fastening body 1B having a holding edge to one end of a holding body 1A having a holding edge for holding a pipe 7. The base end of the clamping bolt 8 is pivotally attached to the other end of the holding body 1A of the clamp body 1, and the distal end of the clamping bolt 8 is engaged and screwed to the engaging portion at the distal end of the clamping holder 1B. Thus, the present invention is applied to a clamp connection structure in which clamps that clamp and hold the pipe 7 are fixedly connected so that the rotation angle can be adjusted.
[0017]
The clamp body 1 has a structure in which the outer surfaces (back surfaces) of the bottom portion of the holding body 1 </ b> A are abutted and connected to each other, and the rotating shaft portion 2 is provided on the bottom portions of the clamp body 1.
[0018]
In this embodiment, the rotating shaft portion 2 is constituted by a disk-like relative rotating disc portion 3 and four fixing pins 9 for fixing the rotating shaft portion 3.
[0019]
Specifically, an attachment hole 10 for locking the relative rotation disk part 3 is opened at the bottom of the holding body 1A of one clamp body 1, and the peripheral part of the relative rotation disk part 3 is formed in the attachment hole 10. The relative rotation disk part 3 is fitted and closed so that the relative rotation disk part 3 is relatively rotatable with respect to the clamp body 1, and is fixed to the relative rotation disk part 3. 9, the fixing pin 9 is passed through a pin hole 11 provided at the bottom of the holding body 1A of the other clamp body 1, and is caulked and locked on the inner surface of the bottom to fix the relative rotating disk 3 to the other. The clamp body 1 is fixedly connected.
[0020]
Accordingly, the relative rotation disk part 3 is integrated with the other clamp body 1, and one clamp body 1 is rotatably connected to the relative rotation disk part 3.
[0021]
Accordingly, the concave locking portion 5 in which the tip end of the locking rod 4 is fitted and engaged with four peripheral portions having different 90-degree rotation angles of the relative rotation disk portion 3 serving as the rotation shaft portion 2. Is forming.
[0022]
Therefore, since it is extremely easy to process and design arbitrarily changing the formation position of the locking portion 5, the restricting rotation angle (0, 90, 180, 270 degrees in this embodiment) is limited to other restrictions. Can be designed without receiving.
[0023]
Further, in this embodiment, parts other than the locking portion 5 of the relative rotating disc portion 3 are processed into a thin plate shape to reduce the weight.
[0024]
Further, the one end of the clamp body 1 is protruded inwardly toward the relative rotation disc portion 3 on the inner surface of the bottom of the clamp body 1, and the base end is protruded to the outside of the clamp body 1. The locking rod 4 is provided so as to be able to advance and retreat, and is configured so that the front end of the locking rod 4 can be engaged with and disengaged from the locking portion 5 of the relative rotation plate portion 3 by moving forward and backward toward the relative rotation plate portion 3. ing.
[0025]
In this embodiment, the locking rod 4 is screwed to the clamp body 1 as a bolt rod 4 and is configured to move forward and backward by rotating the bolt rod 4. A nut 6A is provided in the attachment hole 6 formed in the clamp body 1 so as to communicate with the attachment hole 6 so as to be obliquely arranged on the inner lower side of the main body 1, and the nut 6A provides the attachment hole 6 with the nut 6A. Bolt rod 4 is screwed.
[0026]
Accordingly, in this embodiment, every time the relative rotation disc portion 3 is rotated by 90 degrees, it is possible to engage with the different locking portions 5 by the bolts 4, and this engagement simply protrudes from the outer surface of one clamp body 1. Since it is only necessary to turn the bolt 杆 4 with a finger, it is very easy to fix it with a 90 ° rotation angle, and this rotation angle adjustment is possible even when the pipe 7 is held. In addition, since the direction of engagement / disengagement of the bolt rod 4 and the rotation direction of the relative rotation disc portion 3 are completely different from each other, the relative rotation disc portion 3 may be accidentally rotated or the bolt rod 4 may be It does not come off the locking portion 5, has a very high fixing strength, and is excellent in safety.
[0027]
Further, since the processing of the relative rotating disk part 3 is merely required to make the engaging part 5 engaged with the tip of the bolt rod 4 recessed in the periphery of the relative rotating disk part 3, the engaging part 5 is very different. Therefore, this structure can be easily realized, the mass productivity is high, and the cost is not increased.
[0028]
Note that the present invention is not limited to this embodiment, and for example, the pivoting structure of the rotating shaft portion 2 (relative rotating disc portion 3) can be appropriately designed, and the structure of the clamp body 1 to be applied is also appropriately determined. Can be designed.
[0029]
In the first aspect of the present invention, the locking rod 4 is not the bolt rod 4, and a locking pin rod that can be pulled and released against an elastic body such as a spring can be appropriately designed. .
[0030]
【The invention's effect】
Since the present invention is configured as described above, the rotation angle can be switched and fixed by a simple operation compared to any conventional structure, and the rotation can be adjusted even when the pipe is clamped and held. The structure can be easily designed, so it can be easily mass-produced, it does not increase costs, and the engagement and fixing are secure, the fixing strength is high and the safety is excellent, and it is extremely practical compared to the conventional structure. Excellent clamp connection structure.
[0031]
In the invention according to claim 2, the operation of the locking rod can be easily moved forward and backward, and the mounting structure can be facilitated, and the above-described effect can be exhibited more reliably, resulting in a clamp connection structure that is more practical.
[0032]
In the invention according to claim 3, it is easier to form the locking portion, the above-mentioned effect is more reliably exhibited, and the clamp connection structure is further excellent in practicality.
[0033]
Further, in the invention according to claim 4, it is possible to make the mounting structure of the bolt rod and the rotating operation of the bolt rod easier, and the clamp connecting structure is further improved.
