Description

Technical Field

[0001] The utility model relates to the technical field of hardware fasteners, in particular to an anchor type connecting pin assembly. Background Art

[0002] Anchor pins, as a connecting element widely used in the engineering field, are mainly used for stable connection between profiles. They have a unique design, high strength and locking functions, and can effectively improve the overall stability of the assembly. They have significant advantages, especially in assemblies such as workbenches, material carts, material racks and plates. According to different connection requirements, anchor pins can be divided into universal pins, standard pins, angle pins and diagonal pins.

[0003] Although the anchor type connecting pin has demonstrated excellent performance in terms of connection strength and work efficiency, the problem of connection stability in practical applications cannot be ignored, especially in application scenarios that require high stability and reliability. This problem highlights its importance. Specifically, the root cause of the connection stability problem lies in the single contact surface between the anchor type connecting pin and the profile groove structure. In the existing design, the nail head of the anchor type connecting pin and the profile groove structure can usually only achieve a plane contact. Although this design simplifies the connection process, it also sacrifices the stability of the connection to a certain extent. When the connecting pin is subjected to external force, due to the limited contact area, the stress will be concentrated on this single contact surface, causing the connecting pin to be prone to loosening or displacement. Especially when used for a long time or subjected to strong vibration, impact and other external forces, the instability caused by this single contact surface will be more obvious. This instability will not only reduce the service life of the connecting pin, but may also threaten the stability and safety of the entire assembly. Therefore, it is of great significance to solve the problem of connection stability of the anchor type connecting pin.

[0004] Chinese patent document CN220600187U discloses an anchor type connecting pin assembly, including a connecting pin, the connecting pin including a rod body part and a nail head part, and also including a plug-in column, a connecting hole is provided on the plug-in column along its radial direction, a threaded hole is provided on the plug-in column along its axial direction, the threaded hole is connected with the connecting hole, a positioning pin is threadedly connected in the threaded hole, the rod body part is connected in the connecting hole, a positioning groove is provided on the rod body part along its radial direction, and the positioning pin is plugged into the positioning groove; however, there are still the following defects in the implementation process:

[0005] Although the device in the above document can connect two sections of profiles, during the process of connecting the two sections of profiles, the nail head and the profile groove structure are still in a planar contact, which makes the connecting pin easy to loosen or shift. Especially when used for a long time or subjected to strong vibration, impact and other external forces, the instability caused by this single contact surface will be more obvious. This instability will not only reduce the service life of the connecting pin, but may also threaten the stability and safety of the entire assembly. Utility Model Content

[0043] Example 3

[0044] like Figure 2 , Figure 4 , Figure 5 As shown, on the basis of Example 2, the utility model provides a technical solution: preferably, a movable groove 13 is opened on the side of the inner cavity of the rod body 1 close to the spring 11, the baffle 43 and the spring 3 44 are both located in the inner cavity of the movable groove 13, and the baffle 43 and the spring 3 44 are both slidably connected to the inner cavity of the movable groove 13, the force block 45 is inclined on the side close to the screw assembly 3, a limiting ring block 12 is fixedly connected to the middle part of the outer surface of the rod body 1, and a spring 11 is fixedly connected to the side of the limiting ring block 12 close to the plug-in column 2, and the spring 11 is wound and connected to the rod body 1.

While the rod body 1 moves, the limiting ring block 12 will be driven to apply a force to the spring 11, and then under the cooperation of the plug-in column 2 and the limiting ring block 12, the spring 11 will be driven to contract, and then the threaded nail body 31 will apply a force to the force block 45, pushing the force block 45 to move in the direction away from the screw assembly 3. Then, under the action of the force block 45, the entire top column assembly 4 will be driven to move together, thereby driving the spring three 44 and the baffle 43 to move in the inner cavity of the movable groove 13, and then under the action of the column 41, the rubber block 42 will be driven to move in the direction away from the screw assembly 3, and then the end face of the rubber block 42 will contact the inner wall of the profile groove structure, and then the rubber block 42 will apply a force to the inner wall of the profile groove structure, so that with the cooperation of the rod body 1 and the top column assembly 4, the profile groove structure can be in multi-faceted contact with the device, thereby improving the stability of the profile connection.
