[0002] A rivet gun is a tool used for fastening riveting of various metal plates, pipes, etc. in the manufacturing industry. Currently, it is widely used in the riveting of electromechanical and light industrial products such as automobiles, aviation, railways, refrigeration, elevators, switches, instruments, furniture, and decoration. It is developed to solve the disadvantages such as easy melting of welded nuts for thin metal plates and thin pipes, and easy slipping of internal threads during tapping. The rivet gun can rivet riveting products that do not require tapping of internal threads or welding of nuts, with firm riveting, high efficiency, and convenient and fast use.

[0003] In the use of existing rivet guns, a threaded rod is usually used to connect the rivet nut. A riveting hole is pre - machined on the plate to be connected. The threaded rod passes through the riveting hole, and one end of the threaded rod is connected to the rivet gun, and the other end is thread - connected to the rivet nut. By pulling the threaded rod with the rivet gun, the serrated teeth of the rivet nut are squeezed into the plate to achieve the riveting of the rivet nut and the plate. However, when using a threaded rod for riveting, the rivet gun only applies pressure through the external threads in contact with the rivet nut on the threaded rod, resulting in a short service life of the threaded rod, frequent replacement, and high production costs.

[0004] Therefore, there is an urgent need for a connecting component of a rivet gun and a rivet gun to solve the above problems. Summary of the Invention

[0005] An object of the present invention is to provide a connecting component of a rivet gun, which can improve the service life of the connecting piece, reduce the replacement frequency, and reduce the use cost.

[0028] The present invention will be further described in detail below with reference to the drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present invention, rather than limiting the present invention. In addition, it should be noted that for the convenience of description, only the parts related to the present invention are shown in the drawings, rather than all the structures.

[0029] In the description of the present invention, unless otherwise clearly defined and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] In the present invention, unless otherwise clearly specified and defined, the first feature being "on" or "under" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through additional features therebetween. Moreover, the first feature being "above", "over" and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.

[0031] In the description of this embodiment, the terms such as "upper", "lower", "right", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, so it cannot be understood as a limitation to the present invention. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] As Figure 1 shown, the riveting gun connecting assembly of this embodiment includes a connecting rod 100 and a connecting bolt 200. One end of the connecting rod 100 is provided with an axially arranged first threaded hole 110, and the other end is provided with a connecting portion 120. The connecting rod 100 is passed through the workpiece to be riveted. After the connecting bolt 200 is passed through the riveting nut to be riveted, it is threadedly connected with the first threaded hole 110.

[0033] When using this riveting gun connecting assembly to rivet with a riveting gun, in the axial direction of the connecting rod 100, the connecting length between the connecting bolt 200 and the first threaded hole 110 is greater than the thickness of the riveting nut. The external thread of the part of the connecting bolt 200 connected with the first threaded hole 110 bears the pressure exerted by the riveting gun on the riveting nut. Compared with the prior art where a threaded rod is threadedly connected with the riveting nut, it can increase the length of the part of the thread bearing the pressure, that is, increase the force-bearing area between the connecting rod 100 and the connecting bolt 200, thereby reducing the pressure of the part of the thread bearing the pressure during riveting, and further improving the service life of the connecting rod 100 and the connecting bolt 200, reducing the frequency of replacing the connecting bolt, saving production costs, and improving production efficiency. In addition, compared with the threaded rod in the prior art, the connecting bolt 200 can be purchased using standard fasteners, which is beneficial to further controlling the procurement cost.

[0034] In some embodiments, the connecting portion 120 can be set as a threaded rod or a second threaded hole, and is threadedly connected with the riveting gun, which is convenient for assembly and disassembly and is easy to manufacture. In some other embodiments, the connecting portion 120 can also be detachably connected with the riveting gun by means of snap connection, pin connection, locking connection, etc., which will not be elaborated here.

[0035] Further, the connecting rod 100 includes a protruding portion 130 that protrudes radially along the connecting rod 100. The protruding portion 130 is located between the first threaded hole 110 and the connecting portion 120. When the connecting portion 120 is connected to the riveting gun, the protruding portion 130 can be limited within the riveting gun, further improving the connection strength between the connecting rod 100 and the riveting gun.

[0036] Optionally, in this embodiment, the cross-section of the protruding portion 130 is set to a hexagon, so that the protruding portion 130 can form a structure similar to a nut. When the connecting portion 120 is threadedly connected to the riveting gun, the connecting rod 100 can be rotated by using the protruding portion 130, facilitating the assembly of the connecting rod 100. In some other embodiments, the cross-section of the protruding portion 130 can also be set to a circle, a rectangle, etc., which will not be elaborated here.

[0037] Further, the connecting rod 100 further includes a transition section 140. The transition section 140 is connected to the side of the protruding portion 130 facing the first threaded hole 110. The radial dimension of the cross-section of the transition section 140 is smaller than the radial dimension of the cross-section of the protruding portion 130, and the radial dimension of the cross-section of the transition section 140 is larger than the radial dimension of the cross-section of the end of the connecting rod 100 where the first threaded hole 100 is provided. That is, the protruding portion 130, the transition section 140, and the end of the connecting rod 100 form a stepped structure with a gradually decreasing cross-section. When the riveting gun is riveting, the stress concentration between the end of the connecting rod 100 and the protruding portion 130 can be reduced through the transition section 140, improving the structural strength of the connecting rod 100, and thus increasing the service life of the connecting rod 100.

[0038] Further, the riveting gun connection assembly further includes a protective member 300. The connecting rod 100 passes through the protective member 300. The protective member 300 abuts between the workpiece and the riveting gun, and is used to isolate the workpiece and the riveting gun, preventing the riveting gun from damaging the workpiece due to extrusion during the riveting process and ensuring the surface quality of the workpiece. In this embodiment, the protective member 300 is set as a protective sleeve, and the protective sleeve is sleeved outside the connecting rod 100, with a simple structure, convenient assembly, and low manufacturing cost.

[0039] This embodiment also provides a riveting gun, which includes a riveting gun head and the above-mentioned riveting gun connection assembly. The connecting portion 120 is connected inside the riveting gun head, and the end of the connecting rod 100 where the first threaded hole 110 is provided is located outside the riveting gun head. This riveting gun rivets the riveting nut and the workpiece to be riveted through the above-mentioned riveting gun connection assembly. While ensuring the riveting effect, its components have good structural strength, can reduce the loss of components, reduce the number of component replacements, and is beneficial to saving assembly time and production costs.

[0040] Specifically, the riveting gun head includes a moving member and a housing. The moving member is slidably connected to the housing, and the protruding portion 130 is limited within the housing. The riveting gun further includes a driving mechanism. The moving member is connected to the connecting portion 120 and is in power connection with the driving mechanism. The fixed end of the driving mechanism is fixed to the housing, and the movable end is connected to the moving member for driving the moving member to approach or move away from the workpiece.

[0041] When using this riveting gun, connect the connecting portion 120 of the connecting rod 100 to the moving member. After sleeving the protective member 300 and the workpiece on the connecting rod 100 in sequence, pass the connecting bolt 200 through the riveting nut and tighten it in the first threaded hole 110. Then use the driving mechanism to drive the moving member away from the workpiece. The moving member can drive the connecting rod 100 to move, so that pressure is generated between the head of the connecting bolt 200 and the protective member 300, and the serrations of the riveting nut are squeezed into the workpiece to achieve the riveting of the riveting nut and the workpiece.

[0042] Obviously, the above-mentioned embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
