Abstract
Description
Technical Field
[0001] This utility model relates to the field of binding machine technology, specifically a binding rivet head. Background Technology
[0002] The main function of a binding machine is to punch holes in documents that need to be bound, and then use rivet tubes to bind them. Because it is used more by financial personnel, for example, when they need to bind financial documents, the binding machine can also be called a financial binding machine. However, it is not limited to use by financial personnel; it can also be used in other scenarios where binding is required.
[0003] As can be seen from the above, the binding machine uses a riveting tube to achieve binding. The core component of the riveting process is the riveting head. Before installing the riveting tube, drilling is required. In order to let users know the exact position of the drilled hole, the binding machine is also equipped with laser positioning. However, in the current structure, the structure is relatively large in order to realize the setting of the riveting head and laser positioning structure. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and propose a binding rivet head with a laser positioning and mating structure.
[0005] Compared with the prior art, this utility model proposes a rivet head for binding, including a housing, a heating element, and a rivet head body. The heating element and the rivet head body are both installed in the housing. The rivet head body is located at the lower end of the housing. It also includes a laser through hole for laser positioning. The laser through hole runs from top to bottom through the entire rivet head along the axial direction of the rivet head body. The upper end of the laser through hole is located at the top of the housing, and the lower end of the laser through hole is located at the lower end of the rivet head body. The laser enters from the upper end of the laser through hole and exits from the lower end of the laser through hole.
[0006] In some embodiments, the housing is provided with a limiting part, a mounting cavity and a sleeve hole in sequence from top to bottom. A limiting ring surface is provided between the mounting cavity and the sleeve hole. The rivet head body is installed in the mounting cavity. The rivet head body adopts a T-shaped structure. The cylindrical part of the T-shaped structure is sleeved with the sleeve hole. The annular part of the T-shaped structure is engaged with the limiting ring surface. The rivet head body is axially limited and fixed between the limiting part and the limiting ring surface.
[0007] In some embodiments, the device further includes a heat insulation seat, a limiting part, a heat insulation seat, and a rivet head body arranged sequentially from top to bottom. The heat insulation seat is installed in the mounting cavity, and the heat insulation seat and the rivet head body are axially limited and fixed between the limiting part and the limiting ring surface.
[0008] In some embodiments, the heating element is sandwiched between the lower end of the heat insulation base and the upper end of the rivet head body.
[0009] In some embodiments, the limiting part is provided with a groove in the circumference, and the heat insulation seat is provided with a groove in the vertical direction at the position corresponding to the groove. The groove is connected to the heating element, and the power supply line is electrically connected to the heating element through the groove and the groove in sequence.
[0010] In some embodiments, the laser through-hole sequentially penetrates the limiting part, the heat insulation seat, the heating element, and the rivet head body from top to bottom along the axial direction of the rivet head body.
[0011] In some embodiments, the housing is formed by joining a first part and a second part.
[0012] In some embodiments, the first part and the second part are laterally spliced to form a complete mounting cavity and a socket hole. Before splicing, a rivet assembly consisting of a heat insulation seat, a heating element, and a rivet head body is installed in one part of the mounting cavity and the socket hole, and the rivet assembly is installed and fixed when splicing to form a complete mounting cavity and a socket hole.
[0013] With the above structure, compared with the prior art, the present invention has the following advantages: In the technical solution disclosed herein, a laser through hole is provided, which runs through the entire rivet head from top to bottom along the axial direction of the rivet head body. The upper end of the laser through hole is located at the top of the housing, and the lower end of the laser through hole is located at the lower end of the rivet head body. The laser enters from the upper end of the laser through hole and exits from the lower end of the laser through hole.

[0020] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The embodiments described below are merely examples, and other obvious variations will arise for those skilled in the art. The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0021] Those skilled in the art should understand that, in the disclosure of this utility model, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Therefore, the above terms should not be construed as limitations on this utility model.
[0022] like Figures 1 to 5 As shown, a binding rivet head is disclosed, including a housing 1, a heating element 2, and a rivet head body 3. The heating element 2 and the rivet head body 3 are both installed in the housing 1. The rivet head body 3 is located at the lower end of the housing 1. It also includes a laser through hole 5 for laser positioning. The laser through hole 5 extends from top to bottom through the entire rivet head along the axial direction of the rivet head body 3. The upper end of the laser through hole 5 is located at the top of the housing 1, and the lower end of the laser through hole 5 is located at the lower end of the rivet head body 3. The laser enters from the upper end of the laser through hole 5 and exits from the lower end of the laser through hole 5.
[0023] like Figure 4 As shown, the laser beam 4 penetrates the entire rivet head from top to bottom along the axial direction of the rivet head body 3 and exits from the lower end of the laser through hole 5. In this way, the laser source of the laser positioning structure can have a vertically overlapping position with the rivet head for binding, thereby reducing the volume in the lateral direction.
[0024] In some embodiments, as Figure 5 As shown, the shell 1 is formed by splicing together the first part 1.1 and the second part 1.2. This facilitates manufacturing.
[0025] Further, such as Figure 5 As shown, the first part 1.1 and the second part 1.2 are horizontally spliced to form a complete mounting cavity 7 and a socket hole 8. Before splicing, the rivet assembly consisting of the heat insulation seat 10, the heating element 2, and the rivet head body 3 is installed in one part of the mounting cavity 7 and the socket hole 8, and the rivet assembly is installed and fixed when the complete mounting cavity 7 and the socket hole 8 are spliced together. This makes manufacturing more convenient.
[0026] In some embodiments, as Figure 5 As shown, the housing 1 is provided with a limiting part 6, a mounting cavity 7 and a sleeve hole 8 in sequence from top to bottom. A limiting ring surface 9 is provided between the mounting cavity 7 and the sleeve hole 8. The rivet head body 3 is installed in the mounting cavity 7. The rivet head body 3 adopts a T-shaped structure. The column part 3.1 of the T-shaped structure is sleeved with the sleeve hole 8, and the ring part 3.2 of the T-shaped structure is engaged with the limiting ring surface 9. The rivet head body 3 is axially limited and fixed between the limiting part 6 and the limiting ring surface 9.
[0027] For better thermal insulation and to simplify structural design, such as Figure 4 , 5 As shown, it also includes a heat insulation seat 10, a limiting part 6, a heat insulation seat 10, and a rivet head body 3 arranged sequentially from top to bottom. The heat insulation seat 10 is also installed in the mounting cavity 7. Furthermore, the heat insulation seat 10 and the rivet head body 3 are axially limited and fixed between the limiting part 6 and the limiting ring surface 9.
[0028] Furthermore, the heating element 2 is sandwiched between the lower end of the heat insulation base 10 and the upper end of the rivet head body 3. Therefore, before assembly, the heat insulation base 10, the heating element 2, and the rivet head body 3 can be connected to form a rivet head assembly, and then installed together into a part of the mounting cavity 7 and the socket hole 8. Then, the rivet head assembly is installed and fixed when splicing together to form a complete mounting cavity 7 and socket hole 8.
[0029] In some embodiments, as Figure 1 , 5 As shown, the limiting part 6 is provided with a groove 11 around its circumference, and the heat insulation seat 10 is provided with a groove 12 arranged vertically at the position corresponding to the groove 11. The groove 12 is connected to the heating element 2, and the power supply line is electrically connected to the heating element 2 through the groove 11 and the groove 12 in sequence. In this way, the problem of power supply is solved relatively simply. In addition, combined with the design of the housing 1 being formed by splicing the first part 1.1 and the second part 1.2, when the rivet assembly is installed into one part of the mounting cavity 7 and the socket hole 8, the power supply line is installed together. Then, when the mounting cavity 7 and the socket hole 8 are spliced together to form a complete mounting cavity 7 and socket hole 8, the rivet assembly and the power supply line are installed and fixed.
[0030] Based on the aforementioned structure, such as Figure 4 , 5 As shown, in order to form the laser through hole 5, the laser through hole 5 passes through the limiting part 6, the heat insulation seat 10, the heating element 2, and the rivet head body 3 sequentially from top to bottom along the axial direction of the rivet head body 3.
[0031] It should be noted that the definition of laser in laser beam 4 and laser through hole 5 is a general term. Any applicable positioning light can be used in this disclosure. In this disclosure, these positioning light rays not exemplified are also covered by laser.
[0032] When understanding this disclosure, the above structure may be referred to other embodiments / appendices if necessary. Figure 1 And that is understood, so I will not elaborate further here.
[0033] The above description is merely an illustrative embodiment of this utility model. Therefore, all equivalent changes or modifications made to the structure, features, and principles described in the scope of protection of this utility model are included within the scope of protection of this utility model.
