[0029] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the specific implementation methods, structures, features, and effects according to this utility model application are described in detail below with reference to the accompanying drawings and preferred embodiments. In the following description, different "embodiments" or "embodiments" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0030] like Figures 1 to 6 As shown, a bolt anti-loosening component of this utility model includes: a base plate 1 and a matching member 2; the base plate 1 is provided with a matching hole 1-1; the matching hole 1-1 is a regular polygonal hole; the bottom of the matching hole 1-1 has a limiting member 4; the limiting member 4 can be a limiting ring to prevent the matching member 2 from sliding out from the bottom of the matching hole 1-1. Preferably, the limiting member 4 is integrally formed with the base plate 1 and is formed in one step during the processing of the base plate 1.

[0031] The matching hole 1-1 is at least hexagonal; it can be dodecagonal; or it can be any number of polygonal holes. The matching member 2 is a plate-like structure; its thickness is thinner than the base plate 1 to allow it to fit into the matching hole 1-1 without protruding. The outer wall of the matching member 2 is a polygonal structure, with the same number of sides as the matching hole 1-1, allowing it to match the hole. The matching member 2 can be installed within the matching hole 1-1 and its rotation is restricted by the hole. The matching member 2 is locked into the matching hole 1-1 and cannot rotate. The matching member 2 is provided with a locking hole 2-1; the locking hole 2-1 is concentrically distributed with the outer wall of the matching member 2; it is a regular hexagonal or square hole, used to mate with bolts 6 or nuts to accommodate most bolt and nut structures currently on the market. Preferably, the side length of the locking hole 2-1 is 3 to 30 mm to accommodate most bolt 6 and nut sizes currently available.

[0032] The limiting hole 3 is arranged on the base plate 1; the limiting hole 3 has a predetermined distance from the matching hole 1-1; the predetermined distance can be determined according to the position of the bolt 6 on the equipment. An open pin 5 needs to be fixed on the equipment; the distance between the open pin 5 and the bolt 6 is the same as the predetermined distance, so that the open pin 5 on the equipment can be correspondingly inserted into the limiting hole 3. The limiting hole 3 is multiple; the multiple limiting holes 3 are arranged in an array with the center of the matching hole 1-1 as the center; the interval angle of the multiple limiting holes 3 is 3-12 degrees. After the bolt 6 on the equipment is locked, the matching component 2 with a suitable specification is sleeved on the head of the bolt 6, then the matching hole 1-1 of the base plate 1 is sleeved on the matching component 2 at a suitable angle, so that one limiting hole 3 can correspond to the open pin 5 fixed on the equipment; if the angle has a slight deviation, the bolt 6 can be rotated by a proper angle for adjustment. The opening of the open pin 5 is outward, which not only can limit the rotation of the base plate 1, but also can avoid the base plate 1 from sliding out of the bolt 6.

[0033] The bolt anti-falling assembly can prevent the bolt or the nut from falling off, equipment failure and safety accidents, facilitate replacement of the bolt, facilitate bolt dismounting and maintenance, can be repeatedly used, can be directly installed and continuously used after replacement of the bolt, can be applied to bolts of various specifications, has a simple structure and low use cost.
