A triangular connecting column that can be inserted into the triangular groove is provided on one side of the lower end of the top plate. The triangular connecting column is provided with a screw through-hole. An elephant trunk head is provided on the upper end of the top plate. The elephant trunk head includes a fixed end fixedly connected to one end of the top plate close to the triangular connecting column and a free end extending to the other end. The fixed end of the elephant trunk head is provided with a screw avoidance groove. The upper end of the screw through-hole is placed in the screw avoidance groove. One end of the fixing screw passes through the screw avoidance groove and the screw through-hole and is connected to the connecting threaded hole.

[0005] As a further improvement of the present invention, two symmetrically arranged upper side baffles are provided on the other side of the lower end of the top plate, and two symmetrically arranged lower side baffles are provided on the other side of the upper end of the bottom plate.

[0006] As a further improvement of the present invention, the outer corners on both sides of the chain support block are provided with rounded corner structures.

[0007] As a further improvement of the present invention, rounded corner structures are provided at the outer corners on both sides of the triangular connecting column.

[0008] As a further improvement of the present invention, the inner corners on both sides of the triangular groove are provided with rounded corner structures.

[0009] As a further improvement of the present invention, the elephant trunk is a trunk with a changeable shape.

[0010] As a further improvement of the present invention, the detachable zipper head further includes a pull tab, which is mounted on the trunk head.

[0011] The beneficial effects of the present invention are as follows: the detachable zipper head is connected to the chain support block with a triangular groove through a triangular connecting column, which can achieve limited fixation, prevent the top plate and the bottom plate from twisting and deforming, and ensure stable use effect, and the fixing screw is inserted into the screw avoidance groove at the fixed end of the trunk head, which is not only convenient for installation but also does not expose the nut, making the appearance of the zipper head more beautiful.

DETAILED DESCRIPTION

[0016] In the description of the present invention, it should be understood that if there are descriptions involving orientation, such as orientations or positional relationships indicated by up, down, front, back, left, and right, the orientation descriptions may be based on the orientations or positional relationships shown in the accompanying drawings. This is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0017] In the description of this utility model, if there is a quantity, "several" means one or more, "more" means more than two, "greater than," "less than," and "exceed" are understood to exclude the number itself, while "above," "below," and "within" are understood to include the number itself. The use of the terms "first" and "second" is solely for the purpose of distinguishing technical features and is not to be construed as indicating or implying relative importance, or implicitly specifying the number of the indicated technical features, or implicitly specifying the order of the indicated technical features.

[0018] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0019] like Figures 1 to 3 As shown, the utility model discloses a detachable zipper head, including a top plate 1, a bottom plate 2 and a fixing screw 3. A chain support block 21 is provided on one side of the upper end of the bottom plate 2. The chain support block 21 is a triangular structure and a triangular groove 22 is provided in the middle. A connecting threaded hole 23 is provided at the bottom of the triangular groove 22. A triangular connecting column 11 that can be inserted into the triangular groove 22 is provided on one side of the lower end of the top plate 1. The triangular connecting column 11 is provided with a screw through-hole 12. An elephant trunk head 4 is provided at the upper end of the top plate 1. The elephant trunk head 4 includes a fixed end 41 fixedly connected to one end of the top plate 1 close to the triangular connecting column 11 and a free end 42 extending to the other end. The fixed end 41 of the elephant trunk head 4 is provided with a screw avoidance groove 43. The upper end of the screw through-hole 12 is placed in the screw avoidance groove 43. One end of the fixing screw 3 passes through the screw avoidance groove 43 and the screw through-hole 12 and is connected to the connecting threaded hole 23.

[0020] During assembly, first insert the triangular connecting column 11 of the top plate 1 into the triangular groove 22 of the chain support block 21 of the bottom plate 2 to achieve preliminary reliable limiting fixation of the top plate 1 and the bottom plate 2, and then pass one end of the fixing screw 3 through the screw avoidance groove 43 of the trunk head 4 through the screw through hole 12 and finally connect it with the connecting threaded hole 23 in the triangular groove 22, thus completing the locking fixation.

[0021] The detachable zipper head is connected to the chain support block 21 with a triangular groove 22 through a triangular connecting column 11, which can achieve limited fixation and prevent the top plate 1 and the bottom plate 2 from torsional deformation, thereby ensuring stable use. The fixing screw 3 is inserted into the screw avoidance groove 43 of the fixed end 41 of the trunk head 4, which is not only convenient for installation but also prevents the nut from being exposed, making the appearance of the zipper head more beautiful.

[0022] In the present invention, two symmetrically arranged upper baffles 13 are provided on the other side of the lower end of the top plate 1, and two symmetrically arranged lower baffles 24 are provided on the other side of the upper end of the bottom plate 2 for connecting with the zipper.

[0023] In the present invention, the outer corners on both sides of the chain support block 21 are provided with rounded corner structures to ensure that the zippers on both sides can be smoothly engaged and disengaged.

[0024] In the present invention, the outer corners on both sides of the triangular connecting column 11 are provided with rounded corner structures, and the inner corners on both sides of the triangular groove 22 are provided with rounded corner structures, which reduces stress and facilitates processing and production.

[0025] In the present invention, the trunk 4 is a shape-changing trunk, which is convenient for installing the pull tab. After the pull tab is installed, the trunk 4 can be pressed to make its free end 42 close to the top plate 1 to prevent the pull tab from falling out.

[0026] In the present invention, the detachable zipper head further comprises a pull tab (not shown in the figure), which is mounted on the trunk head 4.

[0027] The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
