Embodiment Construction

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] An anti-falling bolt includes a screw head 1, a stud 2 and a nut 15. It is characterized in that an upper cavity 3 is arranged on the upper part of the stud 2, and a first spring 6 is fixed in the upper cavity 3. The other end of the first spring 6 is connected with a block 5, and the top and bottom of the upper cavity 3 are provided with a chute 4. The chute 4 is configured as a T-shaped groove structure or a dovetail groove structure, which is convenient for the sliding of the block 5 and prevents the When the block 5 is dropped, the top surface of the block 5 is provided with a chamfer on the side away from the first spring 6 .

[0021] The bottom of the stud 2 is provided with a base 7 , a lower cavity 8 is arranged in the base 7 , and a second spring 9 is arranged in the lower cavity 8 .

[0022] The other end of the second spring ...

Abstract

The invention discloses an anti-falling bolt, which comprises a screw head, a stud and a nut. The other end is connected with a block, the bottom of the stud is provided with a base, the base is provided with a lower cavity, the lower cavity is provided with a second spring, and the other end of the second spring is provided with a fixing plate , four grooves are evenly arranged on the side of the fixing plate away from the second spring, and a connecting sphere is arranged in the groove, and one end of the connecting sphere is provided with a fixing rod through welding, and the upper end surface of the nut is evenly arranged. There are four fixing grooves. Compared with the prior art, the structure of the present invention is simple and easy to operate, and can effectively prevent the nut from falling off; when the nut falls off, it can also prevent the bolt itself from falling off, making the bolt connection more stable efficient.

Description

technical field [0001] The invention relates to the field of bolts, in particular to an anti-falling bolt. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with an external thread) that needs to be matched with a nut to fasten and connect two parts with through holes. This form of connection is called a bolted connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. [0003] Bolts are widely used in mechanical production, and in most cases, they need to be used with nuts; when bolted connections are used for a long time, the nut is easy to fall off due to various reasons, resulting in failure of the bolted connection. SUMMARY OF THE INVENTION [0004] In order to solve the deficiencies of the prior art, the purpose of the present invention is to provide an anti-falling bolt with a s...
