Description

Technical Field

[0001] The utility model relates to the technical field of butterfly clip assembly, in particular to an assembly jig for a butterfly clip and a rubber bone. Background Art

[0002] A butterfly clip, also known as a wing clip, gets its name because its shape is similar to that of a butterfly wing. It is a connecting accessory between the shoulder strap / waistband of a backpack and the backpack body. One end of it is provided with a perforation for connecting the end of the shoulder strap / waistband, and the other end is provided with a C-shaped opening, which can bite on the rubber bone at the edge of the backpack body, so as to relatively fix the butterfly clip on the backpack body, and the installation position is relatively flexible and adjustable.

[0003] Considering product quality and use safety, it is generally very difficult for the C-shaped opening of the butterfly clip to move laterally on the rubber bone, that is, it is very difficult to pull out the butterfly clip laterally on the rubber bone. Similarly, it is also very difficult to install the butterfly clip on the rubber bone laterally. Therefore, in the prior art, when assembling the butterfly clip, the butterfly clip is sleeved on the rubber bone at the end of the rubber bone after the rubber bone and the fabric of the backpack body are sewn together, that is, the butterfly clip needs to be assembled before the backpack body is formed, thus interrupting the assembly process of the backpack body. At the same time, due to the functional limitation of the existing cotton-piercing machine, after the butterfly clip is installed on the semi-finished backpack body, the cotton-piercing machine cannot be used for cotton-piercing anymore, and only manual cotton-piercing can be carried out, which puts higher requirements on the experience and technology of workers. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an assembly jig for a butterfly clip and a rubber bone, which can solve the problems existing in the prior art and realize the rapid assembly between the butterfly clip and the rubber bone of a finished backpack.

[0005] To achieve the above purpose, the solution of the utility model is:

[0006] An assembly jig for a butterfly clip and a rubber bone includes a fixing part and an assembling part; the fixing part is provided with at least one mounting hole for locking the assembly jig on a workbench; the first end of the assembling part is fixed on the side of the fixing part, and its second end protrudes from the end face of the fixing part; the second end includes a concave part that is close to the first end and recessed downward, and a clamping part that is far from the first end and has a thickness greater than that of the concave part. The concave part and the clamping part are smoothly transitioned through an inclined surface; a groove is arranged on the inner side of the clamping part for clamping on the surface of the rubber bone, and the end of the groove far from the inclined surface is an open port; the thickness of the concave part is not greater than the width of the C-shaped opening of the butterfly clip; the height of the groove is not less than the diameter of the rubber bone.

[0007] The fixing member is a substrate made of a hard material; the fitting member is formed by wrapping a metal sheet or a metal plate around one side edge of the substrate through a bending process, and the concave portion is formed by a clamping method.

[0008] The relative fixation between the fixing member and the fitting member is achieved by gluing.

[0009] The fitting member includes a first edge wrapping portion fitted on the upper surface of the fixing member and a second edge wrapping portion wrapped around the lower surface of the fixing member, and the overlapping area of the second edge wrapping portion and the fixing member is larger than that of the first edge wrapping portion.

[0010] When a plurality of mounting holes are provided, they are arranged at equal intervals along the length direction of the fixing member.

[0011] After adopting the above technical solution, the utility model has the following technical effects:

[0012] When assembling the butterfly clip of the present utility model, the groove of the clamping portion can be first clamped onto the rubber bone, then the C-shaped opening of the butterfly clip is first clamped onto the concave portion with a smaller thickness, and then the butterfly clip is pushed along the direction of the concave portion and the inclined surface so that its C-shaped opening is slowly expanded until it is pushed to a position away from the clamping portion and just can be sleeved onto the rubber bone, finally realizing the lateral assembly of the butterfly clip onto the rubber bone; thus, when producing a backpack, the butterfly clip can be assembled after the backpack body is assembled as a whole, without affecting the assembly process and the use of the cotton threading machine, and the product quality can be guaranteed.
