[0026] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] The embodiment of the present application provides a plate chain quick-release mechanism, which can achieve rapid removal of pins, improve maintenance efficiency, and significantly reduce maintenance time.

[0028] It should be noted that the first direction mentioned below is the X-axis direction in the drawings of the specification, and the second direction is the Y-axis direction in the drawings of the specification.

[0029] like Figure 1 and Figure 2As shown, an embodiment of the present application provides a plate chain quick-release mechanism, which may include: a base 1, the base 1 is provided with a receiving groove 11, and along the second direction, the two opposite inner walls of the receiving groove 11 pass through the outside of the base 1, and the receiving groove 11 is used to position the plate chain 2; a flip cover 5, the flip cover 5 is hinged to the base 1, one side of the flip cover 5 is provided with a first half-threaded groove 51, and the base 1 is provided with a second half-threaded groove 12, when the flip cover 5 is rotated and fitted onto the base 1, the first half-threaded groove 51 and the second half-threaded groove 12 are fitted to form a threaded through hole, and the length direction of the threaded through hole extends along the first direction; a threaded rod 3, the threaded rod 3 is threadedly connected to the threaded through hole, the threaded rod 3 is connected to an ejector rod 4, and the ejector rod 4 is used to be coaxially arranged with the pin in the plate chain 2. Exemplarily, the receiving groove 11 is provided near the left end of the base 1, and the threaded rod 3 is threadedly connected near the right end of the base 1, that is, the receiving groove 11 and the threaded rod 3 are spaced apart along the first direction, and the left end face of the threaded rod 3 is coaxially fixed with the ejector rod 4 (of course, it can also be coaxially fixed, as long as the ejector rod 4 is coaxial with the pin), and the ejector rod 4 can be driven to move closer to or away from the receiving groove 11 by rotating the threaded rod 3. The hinge axis between the flip cover 5 and the base 1 can be extended along the first direction, and the bottom of the flip cover 5 is provided with a first half-thread groove 51, and the top right end of the base 1 is provided with a second half-thread groove 12. When the flip cover 5 is rotatably attached to the top right end of the base 1, the first half-thread groove 51 and the second half-thread groove 12 are attached to form a threaded through hole, so that the threaded connection between the threaded rod 3 and the base 1 can be realized.

[0030] Specifically, when it is necessary to eject the threaded rod 3, most of the length of the threaded rod 3 can be placed in the second half thread groove 12 in advance to minimize the distance between the ejection rod 4 and the pin, and then the flip cover 5 is closed, the threaded rod 3 is twisted, and the ejection rod 4 is driven to move, so as to realize the ejection of the pin, reduce the number of twisting turns of the threaded rod 3, and improve work efficiency; similarly, when the ejection work of the pin is completed, the threaded rod 3 is rotated in the opposite direction to drive the ejection rod 4 to move out of the plate chain 2, and then the flip cover 5 is opened to directly take out the threaded rod 3, which can also reduce the number of twisting turns of the threaded rod 3 and improve work efficiency, and avoid the traditional form of threaded through hole, which needs to rotate the threaded rod 3 multiple times to make it return to the initial position, so as to facilitate the next disassembly and assembly work.

[0031] Furthermore, the material of the flip cover 5 is metal, and the base 1 is embedded with a first magnet 13; when the flip cover 5 rotates and fits on the base 1, the first magnet 13 attracts the flip cover 5 and limits it to the base 1. Exemplarily, the number of the first magnets 13 can be two, and they are spaced apart along the first direction, installed on the top of the right end of the base 1, and located at the bottom of the flip cover 5; the first magnet 13 attracts the flip cover 5, and limits the flip cover 5 to the base 1, so as to avoid the situation that the flip cover 5 and the base 1 are not tightly fitted, and the restraining force cannot be applied to the threaded rod 3 well, which leads to the situation that the threaded rod 3 and the ejection rod 4 cannot eject the pin of the plate chain.

[0032] Of course, in some embodiments, the base 1 is embedded with the first magnet 13, and the flip cover 5 is embedded with the second magnet, and the magnetic poles of the first magnet 13 and the second magnet are opposite to each other; when the flip cover 5 rotates and fits on the base 1, the first magnet 13 attracts the second magnet, and the flip cover 5 is limited to the base 1. Exemplarily, the first magnet 13 is embedded and installed on the top of the right end of the base 1, and the second magnet is embedded and installed on the bottom of the flip cover 5, so as to further improve the locking and limiting effect between the flip cover 5 and the base 1 when the flip cover 5 rotates and fits on the base 1, and further improve the smoothness of the screwing of the threaded rod 3.

[0033] Further, a buckle slot 52 is provided on one side of the flip cover 5. Exemplarily, a buckle slot 52 is provided on the rear side wall of the flip cover 5, and the buckle slot 52 is convenient for the staff to buckle the buckle slot 52 with their fingers to drive the flip cover 5 to rotate and open.

[0034] Furthermore, in the other pair of opposite inner side walls of the receiving groove 11, and counting along the first direction, a limiting groove 14 is provided on the first inner side wall of the receiving groove 11, and the limiting groove 14 is used to limit the plate chain 2. The limiting groove 14 can limit the panel of the plate chain 2 moved into the receiving groove 11, and when the ejection rod 4 is pushed, the panel of the plate chain 2 is prevented from moving away from the first direction and flipping in the plane where the first direction and the second direction are located.

[0035] Furthermore, the first inner side wall is provided with a through groove 15 along the first direction. The through groove 15 can provide space for the ejected pin to prevent the pin from abutting against the left side wall of the receiving groove 11 along the first direction and being unable to be ejected out of the plate chain 2.

[0036] Furthermore, the ejector rod 4 and the threaded rod 3 are detachably fixed. When the plate chain quick release mechanism is not used, the ejector rod 4 can be removed to reduce the occupied space and facilitate arrangement. At the same time, when the plate chain 2 after the pin is removed needs to be replaced with a new pin, the end of the threaded rod 3 after removal can be used to assemble the ejector pin.

[0037] Furthermore, a bolt head 31 is fixed to one end of the threaded rod 3 away from the ejector rod 4. The bolt head 31 is fixed to the right end of the threaded rod 3. For example, the end face of the bolt head 31 is a regular hexagon or a regular quadrilateral, which is convenient for the subsequent use of a wrench to turn the threaded rod 3.

[0038] Further, the material of the base 1 and the ejector rod 4 includes carbon structural steel. Exemplarily, the base 1 and the ejector rod 4 can be made of 45 type steel, which has higher strength, anti-deformation ability, and ensures service life.

[0039] Furthermore, the structural strength of the ejector rod 4 is greater than that of the pin. In the process of ejecting the pin by the ejector rod 4, the structural strength of the ejector rod 4 is greater than that of the pin, which can ensure that the ejection end of the ejector rod 4 is not easily damaged.
