Description
【Technical field】
This utility model is related to the technical field of securing member, particularly a kind of technical field of practical stop nut.
【Background technology】
Nut is common securing member, traditional nut typically without locking functions, as many nuts are all in machine
Use on device, after start machine, machine can occur a little vibration, therefore when nut uses long, nut will come loose even
Depart from bolt, thus important impact can be caused to the normal operation of machine.
【Utility model content】
The purpose of this utility model is exactly, in order to solve the problems of the prior art, to propose a kind of practical stop nut,
This utility model is not only simple in structure, practical and convenient, and anti-loosing effect is preferable.
For achieving the above object, the utility model proposes a kind of practical stop nut, including cylinder, locking screw
Bolt, limit spring, card and lock sleeve, the cylinder are provided with center hole, screwed hole, card holding tank and groove, institute
State card to be directly installed in card holding tank, the limit spring is arranged between card holding tank and card, the card
Including card circular arc portion, card coupling part and card limited block, the card limited block is by card coupling part and card
Piece circular arc portion is connected, the lock sleeve and the direct fit of cylinder, and the lock sleeve is provided with the projection with fit depressions.
Preferably, when limit spring in the raw when, the card circular arc portion does not extend out center hole, described
Coordinate for gap between card holding tank and card.
Preferably, aperture of the internal diameter of the screwed hole less than center hole, the depth of the center hole is cylinder
The 1/4 of body height, the depth of the screwed hole is the 3/4 of cylinder height.
Preferably, the lock sleeve is six hollow prism structures, the aperture of the lock sleeve is outer more than cylinder
Footpath, the groove and projection are interference fits.
The beneficial effects of the utility model：This utility model is by having opened up the locking positioning dress of spring card on nut
Put, such that it is able to screw bolt and nut effectively be prevented because of prolonged machine vibration, and cause nut to come loose, and then improve spiral shell
Female anti-loosing effect；This utility model is also by the structure using cylinder and lock sleeve split, therefore no lock sleeve one
As spanner and cylinder can be carried out it is elastic, so as to play good anti-theft effect.
Feature of the present utility model and advantage will combine accompanying drawing by embodiment and be described in detail.
【Description of the drawings】
Fig. 1 is a kind of structural representation of practical stop nut of this utility model；
In figure：1- cylinders, 2- clamping screws, 3- limit springs, 4- cards, 5- lock sleeves, 11- center holes, 12- spiral shells
Pit, 13- card holding tanks, 14- grooves, 41- card circular arc portions, 42- cards coupling part, 43- card limited blocks, 51-
It is raised.
【Specific embodiment】
Refering to Fig. 1, a kind of practical stop nut of this utility model, including cylinder 1, clamping screw 2, limit spring 3,
Card 4 and lock sleeve 5, the cylinder 1 are provided with center hole 11, screwed hole 12, card holding tank 13 and groove 14, described
Card 4 is directly installed in card holding tank 13, and the limit spring 3 is arranged between card holding tank 13 and card 4, described
Card 4 includes card circular arc portion 41, card coupling part 42 and card limited block 43, and the card limited block 43 passes through card
Coupling part 42 is connected with card circular arc portion 41, the lock sleeve 5 and 1 direct fit of cylinder, and the lock sleeve 5 is provided with
The projection 51 being engaged with groove 14, when limit spring 3 in the raw when, the card circular arc portion 41 does not extend out center
Circular hole 11, coordinates for gap between the card holding tank 13 and card 4, and the internal diameter of the screwed hole 12 is less than center hole 11
Aperture, the depth of the center hole 11 for 1 height of cylinder 1/4, the depth of the screwed hole 12 is 1 height of cylinder
3/4, the lock sleeve 5 is six hollow prism structures, and the external diameter of the aperture of the lock sleeve 5 more than cylinder 1 is described recessed
Groove 14 and raised 51 is interference fits.
This utility model by the locking positioner of spring card has been opened up on nut, such that it is able to effectively prevent spiral shell
Screw bolt and nut is because of prolonged machine vibration, and causes nut to come loose, and then improves the anti-loosing effect of nut；This utility model
Also by the structure using cylinder and lock sleeve split, therefore the spanner that do not have lock sleeve general cylinder can be carried out
It is elastic, so as to play good anti-theft effect.
Above-described embodiment be to explanation of the present utility model, be not to restriction of the present utility model, it is any new to this practicality
Scheme after type simple transformation belongs to protection domain of the present utility model.
