Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In order to make the technical field of the present invention better understand, the present invention will be described in detail with reference to the accompanying drawings and the detailed description.

Referring to fig. 1 to 5, fig. 1 is a schematic structural view of a pull body provided by the present invention; FIG. 2 is a top view of the pull body; FIG. 3 is a side view of the pull body; FIG. 4 is a side view of the cap; fig. 5 is a bottom view of the cap.

The utility model provides a pull head includes pull body 1, cap 2 and pulling-on piece. The cap 2 is connected with the pull body 1, a mounting hole is formed between the cap and the pull body, and the pull piece is mounted in the mounting hole and can rotate around the axis of the mounting hole. The pull body 1 comprises a top plate and a bottom plate which are connected through a support column 11, and the cap is installed on the top plate of the pull body 1. The pull body 1 is also provided with a connecting hole 12 penetrating through the support column 11, the front end of the cap 2 is positioned above the support column 11 and is connected with the pull body 1, and the front end of the cap 2 is provided with a threaded hole 23 corresponding to the connecting hole 12. The fastening screw passes through the connecting hole 12 to be connected with the threaded hole 23, and the pull body 1 and the cap 2 are fixed through the pretightening force of the bolt.

Optionally, the front portion of the upper end surface of the pull body 1 is provided with a first limiting groove, the first limiting groove is located at the periphery of the connecting hole 12, the front end of the cap 2 is provided with a first insertion part 21 which is located at the periphery of the threaded hole 23 and extends downwards, and the first insertion part 21 is in clearance fit with the first limiting groove. After the first inserting part 21 is inserted into the first limiting groove, the connecting hole 12 is aligned with the threaded hole 23, and the fastening bolt can penetrate through the connecting hole 12 to be connected with the threaded hole 23.

Optionally, since the bottom plate of the pull body 1 is usually facing the inside of the clothes or the container, in order to avoid the nut of the fastening bolt from affecting the movement of the pull body 1 or interfering with the human body or other objects, the connecting hole 12 is specifically a counter-sunk hole. After the fastening bolt is screwed down, the nut can be completely submerged into the countersunk hole, and the lower end face of the pull body 1 is further ensured to be relatively flat.

Furthermore, because the diameter of the fastening bolt is small, the fastening bolt is easy to fall off and lose in the disassembling process, and therefore in order to avoid the loss of the fastening bolt, the middle section of the connecting hole 12 is provided with internal threads. As shown in fig. 3, the diameter of the lower end of the connecting hole 12 is larger than that of the nut, the upper end of the connecting hole is a first limit groove matched with the first inserting portion 21, the diameter of the middle section of the connecting hole 12 is equal to that of the screw rod of the fastening bolt, an internal thread is provided, the middle section of the connecting hole 12 is in threaded connection with the fastening bolt, the fastening bolt is only required to be separated from the connecting hole 12 on the cap 2 during disassembly, and the screw rod is always in threaded fit with the middle section of the connecting hole 12, so that the fastening bolt.

Optionally, when the pull body 1 and the cap 2 are connected, the first inserting portion 21 may be inserted into the first limiting groove, and the cross sections of the first limiting groove and the first inserting portion 21 are both rectangular, and are in clearance fit with each other. The rectangular configuration prevents cap 2 from rotating about first mating portion 21.

Furthermore, a second limiting groove 13 is arranged at the rear part of the upper end surface of the pull body 1, a second insertion part 22 extending downwards is arranged at the rear end of the cap 2, the second insertion part 22 corresponds to the second limiting groove 13 in position, and the second insertion part 22 and the second limiting groove 13 are in clearance fit. When the cap 2 is installed on the pull body 1, the first inserting portion 21 and the second inserting portion 22 are respectively inserted into the first limiting groove and the second limiting groove 13, then the fastening bolt is installed in the connecting hole 12, the first inserting portion 21 and the second inserting portion 22 can offset the torque generated in the installation process of the fastening bolt, and the cap 2 is prevented from rotating.

In the embodiment, the pull body 1 and the cap 2 are connected through the fastening bolt, when the pull piece needs to be replaced, the fastening bolt can be disassembled, so that the pull body 1 and the cap 2 are separated, and the pull piece can be detached and replaced at the moment. In addition, the connecting hole 12 penetrates through the supporting column 11, the abrasion allowance of the supporting column 11 is large, and the slider still has good integrity after being disassembled and assembled for many times, so that the service life of the slider is prolonged.
