Description
[technical field]
The present invention relates to the technical field of the technical field of nut, particularly a kind of multi-functional Anti-loosing screw cap.
[background technology]
The nut generally using in the market generally comprises nut body, is formed on the intrinsic cavity of nut,And be formed on the internal thread on the inwall of nut body. In use, only nut need to be tightened in to boltAbove. But, in some frame for movements, owing to easily producing vibration in the process of device use,Thereby cause nut loosening, once there is unexpected getting loose in nut, tend to cause syndeton to divide to collapse fromAnalyse, cause plant normally to move. Though the mode in bolt and the sealed rear utilisation point glue of nut is enteredRow is bonding, but still can lose efficacy because of embrittlement after long-time use, causes bolt and nut still to exist and get loosePossibility, make troubles to production. Although also there is Anti-loosing screw cap on market, at fastening endWhen phase, the surface of Anti-loosing screw cap and fixation rubs, and easily causes the surface that is fixed impaired, andAnd tighten effort, anti-loose effect is not fine.
[summary of the invention]
Object of the present invention solves the problems of the prior art exactly, proposes a kind of multi-functional Anti-loosing screw cap,Can avoid fixation surface impaired, tighten laborsavingly, and anti-nut gets loose effective.
For achieving the above object, the present invention proposes a kind of multi-functional Anti-loosing screw cap, comprise pedestal, cap body,Spring pad, spring collar, ring groove and screw thread, be provided with screw thread in the through hole of described cap body, described cap bodyTop exert pressure by decompressor, by the through hole top of cap body by the round-shaped elliptical shape that becomes, instituteThe through hole top of stating cap body becomes in the part of elliptical shape at least can set two screw threads, described cap bodyBottom be provided with ring groove, in described ring groove, inserted spring pad, in described ring groove, be inserted withPedestal, described spring pad is located at the top of pedestal, has inserted spring collar, Spring Card in described ring grooveCircle stops that pedestal deviates from ring groove, and described pedestal is by torus and be located at the connector structure on torusBecome, the through hole of described pedestal communicates with the through hole of cap body.
As preferably, it is recessed that the height dimension of described connector adds that the gauge of spring pad is at least greater than annulusThe depth dimensions of groove.
As preferably, described connector and cap body are rotatably connected, and the top of described connector is provided with anticreep platformRank, described spring collar is located at the below of anticreep step, in described ring groove, is provided with spring collar and matchesThe draw-in groove closing.
As preferably, described toric outside dimension is at least greater than the orthohexagonal cornerwise length of cap body,Described toric bottom area is greater than the apex area of connector.
As preferably, the lower end of described toric top and connector is one-body molded fixing.
Beneficial effect of the present invention: the present invention is by exerting pressure the top of cap body, by cap body by decompressorThrough hole top by the round-shaped elliptical shape that becomes, can be closely sealed with screw rod, and after tighteningThe reaction force that cap body obtains by the cooperation of spring pad and pedestal, stops that cap body rotation is loosening, connector withCap body is rotatably connected, and toric bottom area is greater than the apex area of connector, torus be fixedThe frictional force of thing is greater than the frictional force of connector and cap body, and in rundown process, pedestal does not rotate, with prior artCompare, can avoid fixation surface impaired, tighten laborsavingly, and reach dual anti-loose, anti-nutGet loose effective.
Feature of the present invention and advantage will be elaborated by reference to the accompanying drawings by embodiment.
