Abstract

(57) [Summary] [Objective] The present invention relates to a fastening mechanical element including a plate, a shaft with a pawl, a plate with a hole for fixing the pawl, and a shock absorber. [Composition] A Axle 1 with a plate and a plate to support the parts to be fastened. A plate 2 having a hole 6 for fixing the pawl of the B shaft 1. C 3 A shock absorber 3 capable of passing the shaft 1. D Parts 4 and 5 to be fastened, which are perforated so that the shaft 1 can pass therethrough.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a fastening mechanical element including a plate, a shaft with a pawl, a plate with a hole for fixing the pawl, and a shock absorber.

[0002]

[Prior art]

 Conventionally, fastening mechanical elements that can be disassembled without being damaged include bolts and nuts, but they have the drawback that they may come loose and come apart due to vibration.

[0003]

[Problems to be solved by the device]

 This proposal aims to develop a fastening mechanical element that can be disassembled without breaking, with the exception of the fact that it loosens and comes off due to vibration.

[0004]

[Means for Solving the Problems]

 The following is a description of the fastening mechanical elements, which are the means for solving the problem, with reference to the drawings. (The shape of the plate and the cross-sectional shape of the shaft are free. In each drawing, a circular plate and a shaft having a circular cross section are used as examples. B A plate 2 having a hole 6 for fixing the pawl of the shaft 1. Is a circular shape as an example in each figure.) A shock absorber 3 that can pass the C axis 1. (A compression coil is used as an example in each figure.) D axis 1 can be passed Parts 4 and 5 to be fastened with holes (only two plates are shown in each figure as an example).

[0005]

[Action]

 Since the present invention has the structure as described above, when this is used, the parts 4 and 5 to be fastened and the shock absorber 3 are passed through the A-axis 1. B Insert the tab of shaft 1 into plate 2. That is, the tab 7 of the shaft 1 is inserted into the hollow portion 7 of the hole 6. When the plate 2 is rotated to the right while the C-axis 1 is fixed so that it does not rotate, the hole 6 is spiral, so the pawl is bent inward, and finally the snap and the end 8 of the hole are reached. It is fixed and cannot be displaced by vibration. (FIG. 4) D The components 4 and 5 to be fastened are fastened by the restoring force of the compressed shock absorber 3. E By bending the plate 2 to the left while simultaneously bending all the pawls inward, it is possible to disassemble without breaking.

[0006]

【Example】

 In implementing the present invention, the following can be done. A Use a shock absorber other than a compression coil spring. B Change the position of the shock absorber. (FIG. 5) Two C buffers are used. (Fig. 6) The D-thickness and the corresponding holes 6 are made into three or more respectively. E The nail and the hole 6 are shaped so as to be fastened counterclockwise. (FIG. 7) F hole 6 is shaped such that the pawl is bent outward and fits inside. (FIG. 8) G The shape of the hole 6 is made linear rather than spiral. (FIG. 9) The H hole 6 is formed into a shape that is linearly fitted, not rotated. (FIG. 10) I Fix the shaft 1 to the fastening target component 4 by turning the male screw on the shaft 1 and the female screw on the fastening target component 4. J The component 4 to be fastened and the shaft 1 are integrally molded. (Figure 11)

[0007]

[Effect of device]

 Therefore, it is a mechanical element for fastening that does not come off due to vibration and can be disassembled without breaking.
