Technical Field
[0001] This utility model relates to the field of pin technology, and in particular to a pin and a pin connector. Background Technology
[0002] Pins are primarily used at the hinge joints of two parts to form a hinge connection. They can provide a static, fixed connection or allow relative movement between the pin and the connected parts. As fasteners, pins play a crucial role in the connection of mechanical components. Pin connectors, through the engagement of the pin and the shaft hole, connect two or more mechanical parts, enabling them to work together. They not only transmit axial or rotational torque but also ensure the stability and reliability of the connection.
[0003] Most existing pins and pin connectors are used in conjunction with other components to connect and assemble them, such as... Figure 6 As shown, by placing the external connectors to be connected between the connectors, and passing the pin through the connectors and the external connectors, the external connectors and the connectors are connected together by the pin. Then, by inserting a pin into the pin and bending the bottom end of the pin to prevent the pin from falling off, this connection method is simple and quick. However, during the use of the entire device, the device is constantly moving, and the pin will be subjected to the force of the connector. In addition, its own strength is not high, which can easily cause the pin to deform and fall off, which in turn causes the pin to fall off, making it impossible for the components to be connected and used normally.
[0004] To address this, a pin and a pin connector are proposed. Utility Model Content

[0028] As Figures 1 to 5As shown, the pin shaft 2 is provided with a limiting groove 7 for limiting the position of the shaft cap 3, and the shaft cap 3 is slidingly connected in the limiting groove 7, the pin shaft 2 is rotatably connected with a threaded rod 8 for driving the shaft cap 3 to move, and the shaft cap 3 is threadedly connected with the threaded rod 8, the connecting piece 1 is provided with a moving plate 11 for connecting the connecting piece 1 with the pin shaft 2, the connecting piece 1 is provided with a connecting groove 12, and the connecting groove 12 is matched with the bottom of the moving plate 11, when the connecting piece 1, the pin shaft 2 and the external connecting piece are connected together, the external connecting piece is placed between the moving plate 11 and the connecting piece 1, so that the pin shaft 2 passes through the moving plate 11, the external connecting piece and the connecting piece 1, the threaded rod 8 is fixedly connected with a rotating plate 9 for rotating the threaded rod 8, the end of the pin shaft 2 is provided with a recess 10 for accommodating the rotating plate 9, the rotating plate 9 is provided with an anti-skid pad, rotating the rotating plate 9 in the recess 10 drives the threaded rod 8 to rotate, the anti-skid pad can increase the friction, so that it is easier to rotate the rotating plate 9, the rotation of the threaded rod 8 drives the shaft cap 3 to move in the limiting groove 7, the baffle 5 is fixedly connected with the limiting block 4, the push plate 6 is fixedly connected with the shaft cap 3, the push plate 6 and the baffle 5 are both provided with inclined surfaces with the same angle, the movement of the shaft cap 3 drives the push plate 6 to move and makes the push plate 6 apply pressure to the baffle 5, under the cooperation of the inclined surfaces, the baffle 5 gradually moves downward, the downward movement of the baffle 5 drives the limiting block 4 to move downward and makes the limiting block 4 move out of the pin shaft 2, the limiting block 4 is provided with an expansion part 13, the pin shaft 2 is provided with a receiving opening 14, and the expansion part 13 and the receiving opening 14 are fixedly connected with a tension spring 15 for resetting the movement of the limiting block 4, and the movement of the limiting block 4 out of the pin shaft 2 drives the tension spring 15 between the top expansion part 13 and the receiving opening 14 to elongate and generate a counterforce, stopping rotating the rotating plate 9 makes the threaded rod 8 no longer rotate, at this time, the limiting block 4 protrudes out of the pin shaft 2, so that the limiting block 4 limits the pin shaft 2 and makes it unable to move out of the connecting piece 1 and the external connecting piece, and the limiting block 4 replaces the traditional latch, and its strength is much greater than that of the latch, so that the connection stability of the whole device is greatly improved.
[0029] As Figures 1 to 5As shown, in particular, when the external connecting piece is in the connecting piece 1, the thickness of the external connecting piece does not match the distance between the connecting piece 1 and the moving plate 11, the external connecting piece will move left and right on the pin shaft 2, generating unnecessary friction in the left and right directions, and when the distance between the shaft cap 3 on the pin shaft 2 and the limiting block 4 does not match the distance between the connecting piece 1 and the moving plate 11, the pin shaft 2 will move left and right on the connecting piece 1, the external connecting piece and the moving plate 11, also generating unnecessary friction, and such friction will cause the wear of each component to be intensified, the service life of the connecting piece 1 and the pin shaft 2 to be shortened, and the connection stability to be reduced, the torque transmission to be unstable, etc. At this time, the rotating plate 9 can be continuously rotated to drive the threaded rod 8 to rotate, so that the shaft cap 3 continues to move, and at the same time, the movement of the shaft cap 3 from the beginning simultaneously drives the moving plate 11 to move in the connecting groove 12, and the moving plate 11 moves gradually close to the external connecting piece between the moving plate 11 and the connecting piece 1, and the movement of the shaft cap 3 can simultaneously adjust the position of the entire pin shaft 2, so that the connecting piece 1 and the moving plate 11 are attached to the intermediate external connecting piece, and the limiting block 4 is attached to the connecting piece 1, and the moving plate 11 is attached to the shaft cap 3. At this time, the external connecting piece will not move between the moving plate 11 and the connecting piece 1, that is, there is no gap between the external connecting piece and the two, and the pin shaft 2 will not move on the connecting piece 1 under the action of the limiting block 4 and the shaft cap 3, so that the entire device cannot move to generate unnecessary friction, that is, the position of the moving plate 11 and the shaft cap 3 can be adjusted by rotating the rotating plate 9 to drive the threaded rod 8 to rotate, so as to adapt to the matching connection between the pin shaft 2, the connecting piece 1 and the external connecting piece. When the pin shaft 2 is removed, the rotating plate 9 is reversely rotated to drive the threaded rod 8 to rotate, so that the push plate 6 moves in the inner cavity of the pin shaft 2 and is separated from the baffle 5 in the movement. At this time, the baffle 5 is not under the action of the force, and will be driven by the counterforce of the tension spring 15 to move and reset into the inner cavity of the pin shaft 2. The limiting block 4 no longer limits the pin shaft 2 on the connecting piece 1, and then the pin shaft 2 can be removed. The bottom end of the connecting piece 1 is rotatably connected with a connecting column 16, and a threaded hole 17 is formed in the connecting column 16. By arranging the connecting column 16 and the threaded hole 17, the connecting piece 1 can be connected with other components.
