Abstract
The utility model relates to a lock nut which comprises a nut body and a nut cap, wherein, the nut cap is connected with one end of the nut body through welding; more than one nylon ring is coaxially arranged in the inner thread hole of the nut body; and the inner diameter of each nylon ring is smaller than the diameter of the inner thread hole of the nut body. In the utility model, the nut cap is connected with the nut body through welding, so the inner thread hole in the nut body is easier to process and has improved precision. Meanwhile, the nylon ring is arranged in the inner thread hole of the nut body so as to prevent a bolt screwed in the nut from releasing. Besides, the inner wall of the inner thread hole of the nut body is coated with engineering resin, so as to improve the anti-corrosion performance of the nut and further improve the connecting tightness of the bolt and the nut.
Description
Technical field
The utility model relates to a kind of nut of field of mechanical technique, relates in particular to a kind of lock nut.
Background technique
The body of existing acorn nut is structure as a whole with block system; So just requiring need be at the machined internal thread of nut when making; And machining internal thread often need be processed tool withdrawal groove in blind hole, operation inconvenience, and the machining internal thread machining accuracy is also poor in the blind hole.So existing acorn nut difficulty of processing is high.
The model utility content
The purpose of the utility model is to propose a kind of lock nut, and it is easy to processing, and tautness is high, thereby has overcome deficiency of the prior art.
For realizing the foregoing invention purpose, the utility model has adopted following technological scheme:
A kind of lock nut; It is characterized in that: it comprises nut body and block; Said block and nut body one end are welded to connect, and coaxially in the interior threaded hole of nut body are provided with more than one nylon ring, and the internal diameter of said nylon ring is less than the aperture of nut body interior threaded hole.
As a preferred implementation, coating engineering resin layer on the inwall of said nut body interior threaded hole.
As another preferred implementation, be provided with a nylon ring corresponding to block and nut body weld in the interior threaded hole of said nut body.
Compared with prior art, the advantage of the utility model is: adopt nut body and the mode that block is welded to connect, make the interior threaded hole in the nut body be easier to processing, precision also can be improved; Simultaneously, through in the interior threaded hole of nut body, nylon ring being set, can prevent that the bolt that screws in the nut from getting loose; In addition,, can improve its anti-corrosion performance through on the interior threaded hole inwall of nut body, applying engineering resin, and the further tautness that is connected of elevator bolt and this nut.
Description of drawings
Fig. 1 is the structural representation of the utility model one preferred embodiment;
Fig. 2 is the plan view of the utility model one preferred embodiment.
Embodiment
Consult Fig. 1-2, this lock nut comprises nut body 1 and blocks a shot 2, and said block and nut body one end are welded to connect, and the coaxial nylon ring 3 that is provided with in the interior threaded hole of nut body, and the internal diameter of said nylon ring is less than the aperture of nut body interior threaded hole.
Preferably, coating engineering resin layer on the inwall of said nut body interior threaded hole.
Further preferred, said nylon ring 3 is arranged in the interior threaded hole of nut body corresponding to the end of block with the nut body weld.
Above embodiment only supplies to explain the usefulness of the utility model; But not to the restriction of the utility model, the technician in relevant technologies field is under the situation of spirit that does not break away from the utility model and scope; Do various conversion or modification, all belonged to the category of the utility model.
