Description

Technical Field

[0001] This utility model relates to a riveting tool, specifically a rivet nut riveting rod. Background Technology

[0002] A rivet nut gun, also known as a rivet nut gun, is a tool used to install rivets and nuts. Based on their operation, they are mainly divided into two categories: manual and automatic. They are suitable for fastening various metal sheet and pipe manufacturing industries, replacing traditional welded nuts. They eliminate the need for tapping, welding, and internal thread tapping; they overcome the shortcomings of welding thin metal sheets and pipes (easily melting) and the difficulty in smoothly threading welded nuts, providing a quick and easy solution. Existing rivet nut guns include Chinese patent application number 201010588250.3, authorized on July 2, 2014, entitled "Quick Removal Device for Rivet Nut Gun." However, these products are difficult to operate alone and require the use of a gun body, such as Chinese patent application number 201621496059.5, authorized on August 1, 2017, entitled "Single-Handle Rivet Nut Gun." However, these products can only be used with the gun body and are difficult to use independently or in conjunction with a grip. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the purpose of this utility model is to provide a rivet nut riveting rod that solves the technical problems of existing similar products having poor structural design leading to limited usage, inconvenient production and assembly, and difficulty in manual operation via handheld or pistol-style methods. This objective is achieved through the following technical solution.

[0004] A rivet nut connecting rod is disclosed. The rivet nut connecting rod has a fixed sleeve containing a synchronizing rod that reciprocates via a spring. The internal thread of one end of the fixed sleeve's orifice connects to the external thread of one end of the rivet rod. The other end of the connecting rod is a threaded rod. The spring is positioned within a spring cavity formed by the protruding rib on the outer diameter of the synchronizing rod within the fixed sleeve and the spring groove at the opening of the internal thread of the fixed sleeve's inner diameter. The key structural design is that one end of the synchronizing rod within the fixed sleeve is inserted into the end slot of the rivet rod within the fixed sleeve, while the other end of the synchronizing rod extends beyond the other end of the fixed sleeve and is connected to a knob assembly via a screw. The knob assembly then rotates the synchronizing rod within the fixed sleeve. Thus, when the synchronizing rod and the rivet rod are inserted and connected, the rotating assembly drives the synchronizing rod and the rivet rod to rotate synchronously. When replacing the rivet rod, the rotating assembly pulls out the synchronizing rod, disengaging it from the rivet rod, allowing replacement of the rivet rod at the end of the fixed sleeve.

[0005] The knob assembly includes a knob sleeve, a nut, and a knob seat. The flat key head at the end of the synchronizing rod extending from the fixed slide sleeve is connected to the flat key groove inside the knob sleeve of the rotating assembly via the screw. At the same time, the flat key surface of the fixed slide sleeve at this end fits into the flat key hole at the center of the knob seat. The knob seat is fixed to the outer diameter of the fixed slide sleeve by the nut. The positioning hole of the rotating seat and the positioning post of the knob sleeve are connected as one unit.

[0006] The fixed sliding sleeve has an internal hexagonal hole at its end for the riveting rod. The external hexagonal head of one end of the corresponding internal synchronizing rod is inserted into the internal hexagonal hole of the riveting rod. This facilitates synchronous rotation of the synchronizing rod and the riveting rod after connection, improving the stability of the connection.

[0007] The outer diameter of the fixed sliding sleeve is provided with a groove. The gripper is fitted onto the outer diameter of the fixed sliding sleeve and fixed to the groove of the outer diameter of the fixed sliding sleeve by the corresponding flat key edge or screw at the end of the fixed sliding sleeve. The above structure facilitates the gripping operation of the rivet nut riveting rod by the gripper.

[0008] The outer diameter groove of the fixed sleeve has symmetrical openings on both sides, exposing the two sides of the inner synchronizing rod of the fixed sleeve at the openings. The grip is fixedly mounted on the outer diameter of the fixed sleeve and integrated with it. The grip has a handle that is hinged to the grip's swing mechanism. One end of the handle is riveted to the inner synchronizing rod of the fixed sleeve through the opening, and pressing the handle causes the inner synchronizing rod of the fixed sleeve to reciprocate. This structure facilitates the operation of the rivet nut and rivet rod by gripping it with the grip, and also allows for the replacement of the rivet rod through the handle of the grip.

[0009] This utility model has a reasonable structural design, is easy to manufacture and assemble, has low production cost, and has a wide range of applications; it is suitable as a rivet nut riveting rod for direct gripping or gripper operation, and as a structural improvement of similar products.

[0016] The structure and use of this utility model will now be further described with reference to the accompanying drawings. Figures 1-4 As shown, the fixed sleeve 2 of the rivet nut riveting rod is equipped with a synchronous rod 3 that moves back and forth via a spring 4. The internal thread of the inner diameter of one end of the fixed sleeve is connected to the external thread of one end of the riveting rod 1. The other end of the hinge rod is a threaded rod. The spring is limited and set in the spring cavity formed between the rib 301 on the outer diameter of the synchronous rod inside the fixed sleeve and the spring groove at the opening of the internal thread of the fixed sleeve. One end of the synchronous rod inside the fixed sleeve is fitted into the end slot of the riveting rod inside the fixed sleeve, and the other end of the synchronous rod extends out of the other end of the fixed sleeve and is connected to the knob assembly via a screw 8. The knob assembly drives the synchronous rod inside the fixed sleeve to rotate.

[0017] The aforementioned knob assembly includes a knob sleeve 7, a nut 6, and a knob seat 5. The key head at the end of the synchronizing rod extending from the fixed sleeve is connected to the keyway inside the knob sleeve of the rotating assembly via a screw. Simultaneously, the key surface 201 of the fixed sleeve at this end engages with the keyway hole at the center of the knob seat. The knob seat is fixed to the outer diameter of the fixed sleeve by a nut. The positioning hole 501 of the rotating seat and the positioning post 701 of the knob sleeve are integrated. The end of the riveting rod inside the fixed sleeve has an internal hexagonal hole, and the external hexagonal head 302 at one end of the corresponding synchronizing rod inside the fixed sleeve is inserted into the internal hexagonal hole of the riveting rod.

[0018] like Figure 3 As shown, in normal use, turning the knob assembly will cause the entire part to rotate via the synchronizing rod, and the front riveting rod will rotate synchronously and cannot be turned out independently; and the spring will always push the synchronizing rod forward, so the knob will not slide backward naturally.

[0019] like Figure 4 As shown, when changing the rivet rod specification, pull the knob assembly backward, which will drive the synchronizing rod backward and disengage it from the rivet rod. The rivet rod can then be unscrewed independently. After replacing the rivet rod with another specification, reset the knob to complete the replacement.

[0020] Based on the above structural characteristics, such as Figure 5As shown, the outer diameter of the aforementioned fixed sliding sleeve is provided with a groove. The gripper is fitted onto the outer diameter of the fixed sliding sleeve and fixed to the groove of the outer diameter of the fixed sliding sleeve by the corresponding flat key edge 202 or screw at the end of the fixed sliding sleeve. Further, the outer diameter groove of the aforementioned fixed sliding sleeve is provided with symmetrical openings on both sides. The two sides of the inner synchronous rod of the fixed sliding sleeve are exposed at the openings. The gripper is fixedly installed on the outer diameter of the fixed sliding sleeve and connected as a whole. The gripper is provided with a handle 10 that is hinged to the swing of the gripper. One end of the handle is riveted to the inner synchronous rod of the fixed sliding sleeve through the opening. Pressing the handle drives the inner synchronous rod of the fixed sliding sleeve to move back and forth.
