Description

Technical Field

[0001] The utility model relates to the technical field of rivet tools, more particularly to a simple rivet tool. Background Art

[0002] Riveting is a method of fastening two or more components, typically used to connect thin plates or other materials. It's accomplished by inserting a rivet or rivet nut into a pre-drilled hole and then stretching it using a riveting tool to deform it. Traditionally, rivet nuts are riveted by using a hexagonal wrench to secure the hexagonal nut. A pull rod is inserted through the hexagonal nut and the rivet nut. The pull rod is positioned on the hexagonal nut and has a bearing. Turning the rod deforms the rivet nut to complete the riveting process. Washers are typically placed above and below the bearing to ensure proper riveting. However, these tools present several technical challenges and shortcomings:

[0003] The bearing and multiple washers need to be inserted into the screw rod separately, which is complicated to operate. In addition, the insufficient protection of the bearing makes it easy to damage the bearing during the riveting process, resulting in a short service life. The hexagonal nut under the bearing in traditional riveting tools can only be used for fixing and is difficult to buffer the bearing. The flat structure at the bottom makes the rivet nut prone to slipping and idling during riveting, which cannot meet the use requirements. The installation and disassembly process is cumbersome and easy to damage. It may even result in poor stability during riveting, which is prone to errors and affects the quality of riveting.

[0028] A simple riveting tool, see Figure 1-7The present invention is used to install rivet nuts and includes a screw rod 100, a bearing portion 200, and a hexagonal sleeve 300. The screw rod 100 includes a rod head 110 and a rod body 120. The bearing portion 200 and the hexagonal sleeve 300 can be freely rotated and inserted into the rod body 120 of the screw rod 100. Generally, the rod head 110 of the screw rod 100 is larger than the diameter of the rod body 120. The bearing portion 200 and the hexagonal sleeve 300 can be inserted sequentially from the bottom of the rod body 120. When the bearing portion 200 moves up to the bottom of the rod head 110, they will conflict with each other, while the top of the hexagonal sleeve 300 will conflict with the bottom of the bearing portion 200. The bottom of the hexagonal sleeve 300 is provided with a plurality of protruding anti-slip teeth 310; the bearing portion 200 includes a housing 210, a cover 220, and a bearing 230 provided in the housing 210. The bearing 230 is a ball bearing. During use, the bearing portion 200 and the hexagonal sleeve 300 are inserted into the screw rod 100. The bottom of the rod body 120 is inserted into a rivet nut fixed in the desired installation position. The hexagonal sleeve 300 can be fixed with a wrench, and then the screw rod 100 is rotated with the hexagonal wrench. During rotation, a force is applied to the rivet nut to deform. Finally, the rivet nut is deformed and the rivet is fixed. The screw rod 100 is then rotated in the opposite direction to remove it. The bearing 230 ensures that the screw rod 100 can rotate stably and smoothly. The bearing portion 200 is integrated into the housing 210 to protect the bearing 230 and improve its durability. The hexagonal sleeve 300 serves as a transition buffer between the rivet nut and the bearing portion 200, reducing the chance of damage to the bearing portion 230 during rivet operation and increasing its service life. The anti-slip teeth 310 at the bottom of the hexagonal sleeve 300 secure the rivet nut during rivet operation, preventing the rivet nut from slipping. The rivet tool is used for manual riveting, but is not limited to this embodiment. In other embodiments, the rivet tool can be set in a rivet gun for use as a gun head tool of the rivet gun. The bearing part 200 and the hexagonal socket 300 are fixed to the muzzle of the rivet gun, and the screw rod 100 is connected to the rotating shaft of the rivet gun to realize riveting with the rivet gun.

[0029] Furthermore, a sleeve hole 320 matching the rod body 120 is provided in the center of the hexagonal sleeve 300, and the rod body 120 of the screw pull rod 100 is embedded in the sleeve hole 320 to be combined with the hexagonal sleeve 300. A plurality of anti-slip teeth 310 are evenly distributed at the bottom of the hexagonal sleeve 300. In this embodiment, the anti-slip grooves 310 are continuously arranged on the outside of the sleeve hole 320, and the anti-slip grooves 310 can also be arranged at intervals at the bottom of the hexagonal sleeve 300; the top of the hexagonal sleeve 300 is a flat structure to ensure that it fits the bottom surface of the bearing part 200, ensuring that the force on the bearing part 200 can be buffered during riveting.

[0030] Furthermore, the housing 210 and the cover 220 are provided with through holes that match the rod 120, and the screw pull rod 100 is inserted into the bearing portion 200 through the through holes; the housing 210 is provided with a cavity 211, and the bearing 230 and the cover 220 can be embedded in the cavity 211 to be installed on the housing 210, and the bearing hole of the bearing 230 matches the diameter of the rod 120, and the bearing 230 can fit the housing of the rod 120, and the bearing 230 ensures that the screw pull rod 100 rotates stably and smoothly; the outer side of the cover 220 is provided with a spring groove 221 and a fixing spring 222 sleeved on the spring groove 221, and the housing 210 is provided with a fixing spring 222 on the side of the cavity 211 The cover 220 is mounted on the housing 210 by means of a fixing spring 222 and is arranged in the fixing groove 212. The fixing spring 222 is a semi-annular structure. The fixing spring 222 maintains an outward-bouncing force in the fixing groove 212, so that the cover 220 is stably fixed on the housing 210. The bearing 230 is stably arranged in the cavity 211. The cover 220 fits the top of the bearing 230 to prevent the bearing 230 from shifting during riveting. The combined structure of the housing 210, the cover 220 and the bearing 230 makes the bearing part 200 more integrated, which is more convenient and practical than the previous riveting tool structure that requires manual padding of gaskets on the upper and lower sides of the bearing.

[0031] Furthermore, the rod body 120 is provided with threads. The size and threads of the rod body 120 can be set to different specifications according to different rivet nuts to enable rivet nuts of different specifications to be riveted. The top of the rod head 110 is provided with an inwardly recessed hexagonal hole, which is not shown in the figure. The screw rod 100 is inserted into the hexagonal hole and rotated using a hexagonal wrench. The side of the hexagonal sleeve 300 has a hexagonal structure, which facilitates the use of a wrench to fix the hexagonal sleeve 300 during riveting. The length of the rod body 120 is at least 1 cm longer than the combined height of the bearing portion 200 and the hexagonal sleeve 300. This ensures that after the screw rod 100 is installed with the bearing portion 200 and the hexagonal sleeve 300, the bottom length is sufficient to be inserted into the rivet nut and rotated for connection.

[0032] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
