Fig. 1 and 2 show an embodiment of the latch plate of the present invention, in which the latch plate includes a body 10, a locking portion 20 is disposed on a first plate 11 of the body 10, and at least a portion of the locking portion 20 protrudes from the first plate 11.

As shown in fig. 1, after the body 10 is inserted into the pin plate hole of the pin 300, the two long side walls of the body 10 will be pressed against the inner wall of the pin plate hole to generate a pre-tightening force, and the direction of the pre-tightening force generated by the two long side walls of the body 10 is parallel to the first plate surface 11. Elastic locking portion 20 also can compress tightly with the inner wall in bolt diaphragm orifice, produces the pretightning force, and the direction of the pretightning force direction that locking portion 20 produced is perpendicular to first face 11.

Compared with a bolt plate which is tightly pressed against the inner walls of the bolt plate holes by two long-edge side walls of the body 10 in the prior art, the anti-loosening part 20 of the bolt plate can provide pre-tightening force, the direction of the pre-tightening force generated by the anti-loosening part 20 is perpendicular to the direction of the pre-tightening force generated by the two long-edge side walls of the body 10, and the body 10 can be effectively prevented from being separated from the bolt plate holes.

In the embodiment, the anti-loose part 20 is a thin plate structure, made of a metal material, such as stainless steel, copper or aluminum, and thus has elasticity, belonging to a metal spring, and having a thickness of 0.3mm to 0.8 mm.

The body 10 has wide footpath limit 17 and narrow footpath limit 18 along its own length direction, and the width of the wide footpath limit 17 of body 10 is greater than the width of the narrow footpath limit 18 of body, and locking portion 20 includes the first section 21 that extends along the length direction of body 10, and the one end protrusion in first face 11 of the wide footpath limit 17 of keeping away from body 10 of first section 21, and the first section 21 protrusion reduces gradually along the direction from the narrow footpath limit 18 of body 10 to the wide footpath limit 17 of body 10 in the height of first face 11.

When the body 10 is inserted into the bolt plate hole, the first section 21 of the anti-loosening part 20 abuts against the inner wall of the bolt plate hole to generate pressure.

The anti-loose part 20 further comprises a second section 22, one end of the second section 22 is connected with one end of the first section 21, which is far away from the wide diameter side 17 of the body, the other end of the second section 22 extends towards the narrow diameter side 18 of the body 10, and the height of the second section 22 protruding out of the first plate surface 11 is gradually reduced along the direction from the wide diameter side 17 of the body 10 to the narrow diameter side 18 of the body 10.

In this embodiment, the anti-loose portion 20 of the metal elastic sheet is in an arc shape, and in a direction from the narrow diameter side 18 to the wide diameter side 17 of the body 10, a distance that the anti-loose portion 20 protrudes out of the first board surface 11 increases first and then decreases, that is, a highest point of the anti-loose portion 20 protruding out of the first board surface 11 is a connection position of the first section 21 and the second section 22, and a connection position of the first section 21 and the second section 22 is a vertex of the anti-loose portion 20.

As shown in fig. 1, after the body 10 is inserted into the bolt hole, the connection position of the first section 21 and the second section 22 passes through the bolt hole, that is, the vertex of the anti-loosening portion 20 and the narrow diameter side 18 of the body 10 are located on the same side of the bolt hole, so if the body 10 is to move toward the wide diameter side 17, the pre-tightening force needs to be overcome, and the elastic force of the anti-loosening portion 20 needs to be overcome.

In a preferred embodiment, the junction of the first section 21 and the second section 22 is rounded so that the latch plate can be easily installed and removed.

In order to enable the metal elastic sheet-shaped anti-loosening portion 20 to be compressed and rebounded smoothly, one end of the anti-loosening portion 20 is fixed on the body 10, and the other end is a free end and can move relative to the body 10.

In the present embodiment, the end of the second segment 22 close to the narrow diameter side 18 of the body 10 is fixedly connected to the body 10, and the end of the first segment 21 close to the wide diameter side 17 of the body 10 is movable along the length direction of the body 10.
