Description

Technical Field

[0001] This utility model relates to the field of rivet gun technology, and in particular to a rivet rod structure and a rivet gun having the same. Background Technology

[0002] A rivet gun, also known as a rivet gun or rivet nut gun, is a tool used for fastening connections, especially suitable for fastening thin metal sheets and tubes. It solves problems such as the easy melting of nuts in traditional welding and the easy stripping of internal threads. Operated pneumatically or manually, it can complete riveting in one go without tapping or welding, thus improving work efficiency and product quality.

[0003] The rivet rod of an electric rivet gun must withstand maximum torsional force and vibration during operation, which causes it to age and break easily with prolonged use. In existing rivet rod structures, the rod body and the connecting seat to the rivet gun are integrated, making it difficult to repair when damaged and requiring complete replacement. This results in high costs and unnecessary labor time. Summary of the Invention

[0004] The main purpose of this utility model is to propose a rivet rod structure and a rivet gun having the same, aiming to solve the problem that the rivet rod body is not easy to replace in existing rivet rods.

[0005] To achieve the above objectives, this utility model proposes a rivet rod structure, including a pull rod and a sleeve. The sleeve has a connecting hole inside, which extends along the length of the sleeve and penetrates one end wall of the sleeve. The inner wall of the connecting hole has an internal thread corresponding to the position near the opening of the connecting hole. The pull rod has a partial external thread that matches the internal thread. The pull rod can be detachably fixed to the sleeve through the cooperation of the external thread and the internal thread.

[0006] The sleeve is equipped with a pin, and the end of the pull rod near the pin is provided with a locking position. The pin can move relative to the sleeve between a position partially entering the locking position and a position away from the locking position. When the pin is in a position away from the locking position, the pull rod can pivot relative to the sleeve. When the pin is partially entering the locking position, it can restrict the pivoting of the pull rod relative to the sleeve.

[0007] Preferably, a top spring is also provided in the connecting hole, the top spring being used to apply a spring force to the pin to move it in the direction of partially entering the locking position.

[0008] Preferably, one end of the top spring elastically abuts against the inner wall of the connecting hole, and the other end is provided with a pressure block. When the pin is partially located in the locking position, the pressure block abuts against the end wall of the pull rod and covers the locking position.

[0009] Preferably, the pressure block is fixedly connected to the top spring, or the pressure block has a receiving groove into which the end of the top spring can extend.

[0010] Preferably, the pin is fixedly connected to the pressure block, and the pressure block is a metal or plastic product, or the pressure block is a magnet that can be attracted and fixed to the pull rod.

[0011] Preferably, the external thread is located on the pull rod at a position close to the locking position.

[0012] Preferably, the pull rod is provided with a limiting part for abutting against the end wall of the rod sleeve at a position corresponding to the external thread away from the locking position.

[0013] Preferably, a pair of strip-shaped holes are formed through the peripheral wall of the sleeve, and the two ends of the pin are exposed after passing through the two strip-shaped holes respectively.

[0014] Preferably, the sleeve is movably fitted with a collar corresponding to the position of the strip hole. The collar has a positioning hole through which the exposed part of the pin can be inserted. The outer peripheral wall of the collar has an annular groove coaxial with the collar. A rubber ring is provided in the annular groove. The rubber ring is partially located in the positioning hole and abuts against the end wall of the pin.

[0015] This utility model also proposes a rivet gun, including a housing, a gun head, a rivet rod structure, and a drive assembly. The drive assembly is covered with an aluminum protective frame, and the rivet rod structure is the aforementioned rivet rod structure.

[0016] This utility model presents a rivet rod structure formed by the cooperation of a rod body and a sleeve. The sleeve contains a connecting hole into which one end of the rod body can extend. After the rod body end is inserted into the connecting hole, it is screwed and fixed to the rod body via a threaded connection. A pin is movably installed within the sleeve, and a locking position is provided at one end of the rod body for partial entry of the pin. When the pin is partially in the locking position, it restricts the pivoting movement of the rod body relative to the sleeve, thus preventing separation of the rod body from the sleeve. To separate the rod body, the pin is moved until it partially disengages from the locking position, releasing the restriction on the rod body. The pivoted rod body can then be removed from the rivet gun by unscrewing the rod body from the sleeve via the threaded connection. Compared to traditional methods, this utility model's quick-installation and disassembly rod body effectively solves the problem of difficult replacement of the existing rivet rod body. It features a simple structure, convenient operation, and avoids unnecessary labor time. Replacement only requires replacing the rod body, resulting in low replacement costs.

[0026] The sleeve 2 is movably provided with a pin 3, and the end of the pull rod 1 near the pin 3 is provided with a locking position 12. The pin 3 can move relative to the sleeve 2 between partially entering the locking position 12 and moving away from it. When the pin 3 is in the position away from the locking position 12, the pull rod 1 can pivot relative to the sleeve 2. After the pin 3 partially enters the locking position 12, it can restrict the pivoting of the pull rod 1 relative to the sleeve 2.

[0027] Specifically, a top spring 4 is also provided inside the connecting hole 21. The top spring 4 is used to apply a spring force to the pin 3 to move it in the direction of partially entering the locking position 12.

[0028] Specifically, one end of the top spring 4 elastically abuts against the inner wall of the connecting hole 21, and the other end is provided with a pressure block 5. When the pin 3 is partially located in the locking position 12, the pressure block 5 abuts against the end wall of the pull rod 1 and covers the locking position 12.

[0029] Specifically, the pressure block 5 is fixedly connected to the top spring 4, or the pressure block 5 has a receiving groove 51 into which the end of the top spring 4 can extend.

[0030] Specifically, the pin 3 is fixedly connected to the pressure block 5, which is a metal or plastic product, or the pressure block 5 is a magnet that can be attracted and fixed to the pull rod 1.

[0031] Specifically, the external thread 11 is provided on the pull rod 1 at a position close to the locking position 12.

[0032] Specifically, the pull rod 1 is provided with a limiting part 13 at the position of the external thread 11 away from the locking position 12 for abutting against the end wall of the sleeve 2.

[0033] Specifically, a pair of strip-shaped holes 22 are formed through the peripheral wall of the sleeve, and the two ends of the pin 3 are exposed after passing through the two strip-shaped holes 22 respectively.

[0034] Specifically, the sleeve 2 is movably fitted with a collar 6 corresponding to the position of the strip hole 22. The collar 6 has a positioning hole 61 through which the exposed part of the pin 3 can be inserted. The outer peripheral wall of the collar 6 has an annular groove 62 coaxial with the collar 6. A rubber ring is provided in the annular groove 62. The rubber ring is partially located in the positioning hole 61 and abuts against the end wall of the pin 3.

[0035] This utility model also proposes a rivet gun, including a housing 7, a gun head 8, a rivet rod structure, and a drive assembly. The drive assembly is covered with an aluminum protective frame 9. For the specific structure of the rivet rod structure, please refer to the above embodiments. Since this rivet gun adopts all the technical solutions of all the above embodiments of the rivet rod structure, it has at least all the beneficial effects brought about by the above technical solutions of the rivet rod structure, which will not be described in detail here.

[0036] Specifically, a rivet gun mainly consists of a housing and a drive mechanism; the specific structure can be found in existing technologies, such as... Figure 2 As shown, when installing the rivet rod structure, the end of the rod sleeve 2 near the driving end of the rivet gun drive mechanism has a non-circular insertion hole 14. A plug block 100 with a shape matching the insertion hole 14 is provided on the driving end of the rivet gun drive mechanism. The rod sleeve 2 and the driving end of the rivet gun drive mechanism are detachably and fixedly connected through the insertion of the insertion hole 14 and the plug block 100. Of course, achieving a detachable connection through the insertion of the insertion hole 14 and the plug block 100 is only one implementation method; other connection methods can also be used, such as threaded connections, snap-fit ​​connections, etc.

[0037] This utility model presents a rivet rod structure formed by the cooperation of a rod body and a sleeve. The sleeve contains a connecting hole into which one end of the rod body can extend. After the rod body end is inserted into the connecting hole, it is screwed and fixed to the rod body via a threaded connection. A pin is movably installed within the sleeve, and a locking position is provided at one end of the rod body for partial entry of the pin. When the pin is partially in the locking position, it restricts the pivoting movement of the rod body relative to the sleeve, thus preventing separation of the rod body from the sleeve. To separate the rod body, the pin is moved until it partially disengages from the locking position, releasing the restriction on the rod body. The pivoted rod body can then be removed from the rivet gun by unscrewing the rod body from the sleeve via the threaded connection. Compared to traditional methods, this utility model's quick-installation and disassembly rod body effectively solves the problem of difficult replacement of the existing rivet rod body. It features a simple structure, convenient operation, and avoids unnecessary labor time. Replacement only requires replacing the rod body, resulting in low replacement costs.
