Abstract
Description
Technical Field
[0001] This utility model relates to a long-stroke rivet gun, belonging to the field of hardware tools. Background Technology
[0002] Riveting guns are used for fastening and riveting various metal sheets and pipes in the manufacturing industry. They are widely used in riveting of electromechanical and light industrial products such as elevators, switches, instruments, furniture, and decorations. Developed to address the shortcomings of welding nuts to thin metal sheets and pipes, such as easy melting and stripping of internal threads, rivets can rivet products that do not require internal threading or welding nuts. Currently, most rivet guns only move the rivet core by moving the sleeve, collet, claw, and top core during the riveting process, resulting in a short stroke and low riveting efficiency, as illustrated by the rivet gun disclosed in application number 202222724839.2. Utility Model Content
[0003] The purpose of this invention is to overcome the above-mentioned shortcomings in the existing technology and to provide a long-stroke rivet gun with a reasonable structural design.
[0004] The technical solution adopted by this utility model to solve the above problems is: the long stroke rivet gun includes a fixing device, a handle device and an inner pull device. The handle device is installed on the fixing device. Its structural feature is that it also includes an outer push device. The outer push device is installed on the fixing device, and the inner pull device is installed on the outer push device. Both the inner pull device and the outer push device are connected to the handle device.
[0005] Furthermore, the push-out device includes a push-out sleeve, a push-out top seat, and a pull nozzle. The push-out sleeve is mounted on a fixing device and connected to a handle device. The push-out top seat is mounted on the push-out sleeve, and the pull nozzle is mounted on the push-out top seat.
[0006] Furthermore, the pusher device also includes a pusher shaft, which is mounted on the handle device and connected to the pusher sleeve.
[0007] Furthermore, the outward pushing device also includes an outer spring, one end of which abuts against the outward pushing sleeve, and the other end of which abuts against the inner pulling device.
[0008] Furthermore, the inner pull device includes an inner pull sleeve, an inner pull clamp, a claw, a top core, and an inner spring. The inner pull sleeve is located inside the outer push top seat. The inner pull clamp is installed on the inner pull sleeve. The claw is located inside the inner pull clamp. The top core and the inner spring are both located inside the inner pull sleeve. The two ends of the inner spring abut against the top core and the inner pull sleeve, respectively. The two ends of the claw cooperate with the top core and the pull nozzle, respectively.
[0009] Furthermore, the inner pull device also includes an inner pull pin, an inner pull connecting rod, an inner pull base, and a hinge shaft. The inner pull pin is mounted on the handle device and is hinged to one end of the inner pull connecting rod. The other end of the inner pull connecting rod is hinged to the inner pull base via the hinge shaft. The inner pull base is mounted on the inner pull sleeve.
[0010] Furthermore, the fixing device includes a fixing frame, a fixing cover, and fixing bolts. The fixing cover is mounted on the fixing frame by the fixing bolts, and the handle device is mounted on the fixing bolts.

[0024] The long-stroke rivet gun in this embodiment includes a fixing device 1, a handle device 2, an external push device 3, and an internal pull device 4. The handle device 2 is mounted on the fixing device 1, the external push device 3 is mounted on the fixing device 1, and the internal pull device 4 is mounted on the external push device 3. Both the internal pull device 4 and the external push device 3 are connected to the handle device 2.
[0025] In this embodiment, the external push device 3 includes an external push shaft 31, an external push sleeve 32, an external push top seat 33, a pull nozzle 34, and an external spring 35. The external push sleeve 32 is mounted on the fixing device 1 and is connected to the handle device 2. The external push top seat 33 is mounted on the external push sleeve 32, and the pull nozzle 34 is mounted on the external push top seat 33.
[0026] In this embodiment, the outer push shaft 31 is mounted on the handle device 2 and is connected to the outer push sleeve 32. One end of the outer spring 35 abuts against the outer push sleeve 32, and the other end of the outer spring 35 abuts against the inner pull device 4.
[0027] The inner pull device 4 in this embodiment includes an inner pull pin 41, an inner pull connecting rod 42, an inner pull base 43, a hinge shaft 44, an inner pull sleeve 45, an inner pull clamp 46, a claw 47, a top core 48, and an inner spring 49. The inner pull sleeve 45 is located inside the outer push top seat 33, the inner pull clamp 46 is installed on the inner pull sleeve 45, the claw 47 is located inside the inner pull clamp 46, the top core 48 and the inner spring 49 are both located inside the inner pull sleeve 45, the two ends of the inner spring 49 abut against the top core 48 and the inner pull sleeve 45 respectively, and the two ends of the claw 47 cooperate with the top core 48 and the pull nozzle 34 respectively.
[0028] In this embodiment, the inner pull pin 41 is mounted on the handle device 2, and one end of the inner pull pin 41 is hinged to the inner pull connecting rod 42. The other end of the inner pull connecting rod 42 is hinged to the inner pull base 43 through the hinge shaft 44. The inner pull base 43 is mounted on the inner pull sleeve 45.
[0029] The fixing device 1 in this embodiment includes a fixing frame 11, a fixing cover 12 and a fixing bolt 13. The fixing cover 12 is installed on the fixing frame 11 by the fixing bolt 13, the handle device 2 is installed on the fixing bolt 13, and the waste nail box 14 is installed on the fixing frame 11.
[0030] The handle device 2 in this embodiment includes a left handle 21 and a right handle 22. The left handle 21 and the right handle 22 are respectively mounted on two fixing bolts 13. Each of the left handle 21 and the right handle 22 is equipped with an external push pin 31 and an internal pull pin 41.
[0031] Specifically, when using this long-stroke rivet gun, opening the left handle 21 and right handle 22 allows them to rotate along the fixing bolt 13. Simultaneously, the inner pulling device 4 moves upward and the outer pushing device 3 moves downward, causing the inner spring 49 to press against the top core 48. The top core 48 then actuates the claw plates 47, causing them to contact the rivet nozzle 34, thus separating multiple claw plates 47. Figure 5 As shown.
[0032] Insert the rivet core into the pull nozzle 34, close the left handle 21 and right handle 22 to make them rotate along the fixing bolt 13, and at the same time, the inner pull device 4 moves downward and the outer push device 3 moves upward, so that the inclined surface on the inner pull sleeve 46 contacts the inclined surface on the multiple claw pieces 47, so as to retract the multiple claw pieces 47. Figure 4 As shown, at the same time, the rivet core can be clamped and pulled out by multiple claws 47 to complete the riveting action. The opening and closing action of the left handle 21 and the right handle 22 is continuously cycled until the rivet core is broken. The outer spring 35 can press the inner pull base 43 against the outer push sleeve 32, so that the inner pull base 43 moves down and pulls the inner pull connecting rod 42 and the inner pull sleeve 45 down, thereby realizing the reset of the left handle 21 and the right handle 22.
