Embodiment Construction

[0033] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] Please also refer to figure 1 and Figure 4 , the anti-loosening screw provided by the present invention is now described. The anti-loosening screw includes a bolt 1, a connector, and a nut 2. The end of the bolt 1 is provided with a notch, and the notch extends along the length direction of the bolt 1 and penetrates both sides of the bolt 1; When the bolt 1 is axially inserted into the notch and the rotation is limited in the notch, the exposed part of the socket from the notch is the first conflicting part; the nut 2 is used for threaded connection with ...

Abstract

The invention provides a lock screw, and belongs to the technical field of connection and fastening. The lock screw comprises a bolt, a nut, and an inserted connector, a groove opening is formed in the end of the bolt, extends in the length direction of the bolt and penetrates through the two sides of the bolt, the inserted connector is used for being inserted into the groove opening in the axialdirection of the bolt and rotatably limited in the groove opening, the part, exposed from the groove opening, of the inserted connector is a first propping part, the nut is used for being in threadedconnection with the bolt, and a second propping part used for being in clamped connected with the first propping part to limit the rotation of the nut. The lock screw solves the problems that the self-locking ability of an existing bolt and nut connection manner and loosening often happens.

Description

technical field [0001] The invention belongs to the technical field of connection and fastening, and more specifically relates to an anti-loosening screw. Background technique [0002] The threaded connection has a high degree of standardization, is easy to disassemble, assemble and manufacture, and can adapt to various working conditions, so it is widely used. However, after a long period of use, the threaded connections of bolts and nuts often loosen due to various factors such as friction, vibration, temperature, etc., and the loosening of bolts and nuts may affect the operation of the equipment and even cause danger. Contents of the invention [0003] The object of the present invention is to provide an anti-loosening screw, aiming at solving the problem of low self-locking ability and frequent loosening in the existing bolt-nut connection. [0004] In order to achieve the above object, the technical solution adopted by the present invention is to provide a kind of an...
