Description

Anti-loose stop nut

Technical Field

The utility model relates to a lock nut's technical field, concretely relates to locking stop nut.

Background

The hydraulic oil cylinder is a common hydraulic actuating element which does linear reciprocating motion, and a locking nut is generally screwed on the end part thread of a piston rod of the hydraulic oil cylinder, so that the thread is prevented from loosening, the connection stress between the threads is stronger, and the normal use of the hydraulic oil cylinder is ensured. In the actual use process, however, the locknut moves back and forth along with the piston rod, and the locknut is subjected to frequent impact force, so that the situation of loosening can often occur, and the use of the hydraulic oil cylinder is influenced; the applicant therefore proposes to design a locknut that solves the above mentioned problems.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, to the above-mentioned not enough of prior art, provide a locking lock nut.

For realizing the purpose, the utility model adopts the following technical proposal:

a locking stop nut is used for being installed at the end part of a piston rod of an oil cylinder and comprises a nut body, wherein a first screw hole is formed in the middle of the nut body, a groove is formed by inwards cutting one side of the first screw hole, and the part cut off in the groove is a pressing block;

a second screw hole is formed in the groove along the radial direction of the nut body;

the end part of the piston rod is provided with external threads, the pressing block is installed in the groove in an adaptive mode, the nut body and the pressing block are screwed on the piston rod and screwed to the tightest degree, and a fastening screw is screwed into the second screw hole and abuts against the outer arc surface of the pressing block.

The utility model has the advantages that:

the utility model discloses a locking stop nut processes recess and compact heap on the nut body, with the compact heap slip-in recess, then screws the nut body on the piston rod, offsets fastening screw in second screw with the compact heap again, and fastening screw compresses tightly the compact heap, makes the nut body connect with the piston rod soon more inseparabler, avoids the nut body the not hard up condition to appear, realizes the effect of nut body locking.

Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments; in the following description, specific details are provided, such as specific configurations and components, merely to facilitate a thorough understanding of embodiments of the invention. Thus, it will be apparent to those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the invention. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.

In the present invention, the embodiments and the features of the embodiments may be combined with each other without conflict.

As shown in fig. 1-6, the anti-loose stop nut provided by this embodiment is installed on an external thread at an end of a piston rod 200 of an oil cylinder, and includes a nut body 100, wherein a first screw hole 110 is formed in a middle portion of the nut body 100, a groove 120 is cut and formed by a wire cutting processing manner inwards at one side of the first screw hole 110, and a portion cut from the groove 120 is a pressing block 130; and the pressing block 130 can slide up and down in the groove 120; a second screw hole 140 is formed in the groove 120 along the radial direction of the nut body 100, and the fastening screw 150 can be screwed into or out of the second screw hole 140.

The tip of piston rod 200 is equipped with the external screw thread, when using, install compact heap 130 adaptation in recess 120, connect nut body 100 and compact heap 130 soon on piston rod 200, and revolve to tightest, again with fastening screw 150 screw in second screw 140 in offset with the extrados of compact heap 130, fastening screw 150 compresses tightly compact heap 130, it is inseparabler to make nut body 100 connect soon with piston rod 200, avoid nut body 100 the not hard up condition to appear, realize the effect of nut body 100 locking.
