[0017] In order to more clearly illustrate the technical solutions in the embodiments of the utility model or the prior art, the utility model will be briefly introduced below in combination with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the utility model. For ordinary technicians in this field, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the utility model, but does not constitute a limitation of the utility model.

[0018] Example:

[0019] like Figure 1 and Figure 2 As shown, this embodiment provides a pin positioning device in the steering wheel airbag assembly process. In actual operation, the steering wheel airbag is set with the side with the pin facing upward to facilitate cooperation with the pin positioning device.

[0020] The pin positioning device includes a positioning frame 1, a slider 2 and a T-wrench 3. A circular pin positioning hole 101 matching with the pin is provided at one end of the positioning frame 1. A pin on the steering wheel airbag can be inserted into the circular pin positioning hole 101 to realize the positioning of the pin. The slider 2 is slidably connected to the other end of the positioning frame 1 in a direction away from or close to the circular pin positioning hole 101, and a long hole 201 slidingly matched with the pin is provided on the slider 2. When installing the pin positioning device, the long hole 201 can allow a certain error in the spacing between the two pins, and then the inner wall of the circular pin positioning hole 101 is abutted against another pin through the sliding of the slider 2, and then the two pins are limited to the specified position through the pin positioning device, and deformation of the pins can be avoided during the assembly and screwing process.

[0021] The T-shaped wrench 3 includes a rotating rod and a handle portion at one end vertically connected to the rotating rod, so as to control the rotation of the rotating rod through the handle portion; one end of the rotating rod close to the circular pin positioning hole 101 is rotatably connected to the positioning frame 1, and the other end of the rotating rod is threadedly connected to the slider 2 to ensure the stability of the rotating rod, and when the T-shaped wrench 3 is rotated, the other end of the rotating rod can make the slider 2 slide on the positioning frame 1, and then the slider 2 can be easily adjusted to the specified position; a handle limit groove perpendicular to the rotating rod is provided on the positioning frame 1 on one side of the rotating rod, so as to clamp the rotated handle portion through the handle limit groove, so that when the handle portion is just clamped in the handle limit groove, the slider 2 also slides to the specified position, thereby ensuring the stability of the slider 2 without the need to continue to control it by hand.

[0022] When the utility model is in use, one pin of the steering wheel airbag is inserted into the circular pin positioning hole 101, and the other pin is inserted into the elongated hole 201, and then the T-shaped wrench 3 is rotated by the handle portion of the T-shaped wrench 3, and the sliding block 2 can be controlled to slide toward the circular pin positioning hole 101 by means of the threaded connection between the rotating rod and the sliding block 2, so that the circular pin positioning hole 101 and the elongated hole 201 cooperate to ensure the stability of the two pins, and the two pins can be guaranteed not to be deformed during the assembly and screwing process, and the operation is simple and convenient. After the T-shaped wrench 3 is rotated into place, the handle portion can be directly matched and clamped in the handle limit groove, and while ensuring that the sliding block 2 slides to the specified position, the stability of the sliding block 2 can also be guaranteed without the need for continued manual control, thereby further improving convenience.

[0023] As a preferred implementation scheme in this embodiment, it needs to be further explained that the other end of the positioning frame 1 is provided with a slide groove running through the top and bottom thereof, which does not affect the pin passing through the long hole 201 of the slider 2, and slide rails 102 are provided on the inner walls on both sides of the slide groove. Slide grooves are provided on both sides of the slider 2, and the slide grooves on both sides of the slider 2 slide with the two slide rails 102 respectively to ensure the stable sliding of the slider 2 in the slide groove.

[0024] As a preferred implementation scheme in this embodiment, it needs to be further explained that a compression spring 4 is arranged in the slide groove, and one end of the compression spring 4 close to the circular pin positioning hole 101 is connected to the end of the slider 2 away from the circular pin positioning hole 101, and the other end of the compression spring 4 is connected to the end of the slide groove away from the circular pin positioning hole 101. The compression spring 4 can always give the slider 2 a thrust in the direction of the circular pin positioning hole 101. When there is a movable gap between the handle part of the T-shaped wrench 3 and the handle limiting groove, the thrust given to the slider 2 by the compression spring 4 can also enhance the stability of the slider 2.

[0025] As a preferred implementation scheme in this embodiment, it needs to be further explained that the slide groove is set at an opening at one end away from the circular pin positioning hole 101, and the opening is detachably connected to the limit plate 103 by bolts, and the other end of the compression spring 4 is connected to the limit plate 103, which facilitates the loading and unloading of the compression spring 4 and the slider 2, making the assembly of the equipment more convenient.

[0026] As a preferred implementation scheme in this embodiment, it needs to be further explained that one end of the slider 2 and the end of the limit plate 103 facing the slide groove are both provided with limit holes, and the two ends of the compression spring 4 are respectively arranged in the two limit holes, which can further enhance the stability of the compression spring 4, thereby ensuring the stability of the thrust given to the slider 2 by the compression spring 4.

[0027] As a preferred implementation scheme in this embodiment, it needs to be further explained that the positioning frame 1 is a rectangular structure with a simple structure. The circular pin positioning hole 101 extends downward to form a circular protrusion 104, and the long hole 201 extends downward to form a U-shaped protrusion 202. Therefore, when in use, the circular protrusion 104 and the U-shaped protrusion 202 can be made to contact the steering wheel airbag surface, thereby ensuring the structural stability and avoiding interference between the positioning frame 1 and the steering wheel airbag. Of course, in practice, the lower end of the positioning frame 1 can also be provided with an avoidance groove according to the situation, which not only ensures the structural stability itself, but also ensures stable cooperation with the steering wheel airbag.

[0028] As a preferred implementation scheme in this embodiment, it needs to be further explained that the pin positioning device also includes a T-shaped sleeve 5, and the handle of the T-shaped wrench 3 is inserted into the T-shaped sleeve 5, which is convenient and simple to use.

[0029] As a preferred implementation scheme in this embodiment, it needs to be further explained that one end of the rotating rod is rotatably connected to the positioning frame 1 through a bearing, and the other end of the rotating rod is a threaded rod structure. The slider 2 is provided with a thread groove that cooperates with the thread at the other end of the rotating rod, thereby ensuring the stability of the rotating rod and enabling the rotation of the rotating rod to drive the slider 2 to slide.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
