Abstract
The invention discloses a locknut which comprises a nut body, wherein an anti-loosing groove is arranged in the nut body, a rubber ring and a pressure ring are arranged in the anti-loosing groove, the pressure ring is positioned at the outer side of the rubber ring, a first guide inclined surface is arranged in the nut body, a second guide inclined surface is arranged on the pressure ring, the upper end surface and the lower end surface of the rubber ring are respectively adapted to the first guide inclined surface and the second guide inclined surface, and when the nut body is in a use state, interference fit is respectively formed between the rubber ring and the inner side of the anti-loosing groove, between the rubber ring and the pressure ring and between the rubber ring and a screw rod. In the invention, an additional special tool is not needed for screwing the nut, the locknut is convenient to use, and the nut can not loose due to vibration after being tightly screwed.
Description
Technical field
The present invention relates to a kind of Component that are used to be fastenedly connected, particularly a kind of lock nut.
Background technique
Need use a large amount of nuts in fields such as railway, bridge, airport, aviations and carry out the fastening of equipment, but under the violent vibration environment that various mechanical motion produce, common nut tends to be shaken pine and the inefficacy that comes off, and leads to major accident.Therefore usually the nut outside of screw threads for fastening parts around on a few circle iron wires, carry out locking.In fact this locking measure can only prevent that nut from coming off, and can not make nut anti-looseness, but when nut unclamps, has existed huge potential safety hazard, therefore develops a kind of can the repeated use, and the good special-purpose lock nut of effect just seems very necessary.
In order to solve the locking problem of nut, a large amount of scientific experimentations and research have been done by lot of domestic and international enterprise.They adopt locking plate, ratchet, inserted sheet, pin, distortion screw thread, nylon embedded piece and chemical gluing method, even with the method for a plurality of nuts stack, solve the locking problem of nut.Facts have proved above measure owing to there is the shortcoming that can't overcome, for example need special-purpose instrument, nut fastener corrosion special tool is over a long time used inefficacy, can't regulate to cause equipment to be scrapped, the high low temperature of chemical material, damp and hot inefficacy can disposablely be used to the greatest extent etc.Therefore to a certain extent, the locking problem of nut does not obtain satisfied solution to a certain extent over a long time.
Summary of the invention
In order to address the above problem, the object of the present invention is to provide a kind of need not be extra special tool and can be behind the nut screwing clamping because of the loosening lock nut of vibrations.
The present invention solves the technological scheme that its problem adopts: a kind of lock nut, comprise nut body, be provided with an antiratchetting groove in the described nut body, be provided with a glue ring and a pressure ring in the described antiratchetting groove, pressure ring is positioned at the glue ring outside, be provided with first guiding surface in the nut body, pressure ring is provided with second guiding surface, the upper-end surface of glue ring and lower end surface are suitable with first and second guiding surface respectively, when nut body is in user mode, between the inboard of described glue ring and antiratchetting groove and the pressure ring and and screw rod between be interference fit.
Technique scheme also can have following improvement project: the outside of described antiratchetting groove is provided with a fastening step.
The invention has the beneficial effects as follows: owing to be provided with an antiratchetting groove in the described nut body, be provided with a glue ring and a pressure ring in the described antiratchetting groove, fastening nut need not be extra special tool, easy to use, behind nut screwing clamping, between the inboard of described glue ring and antiratchetting groove and the pressure ring and and screw rod between be interference fit, the glue ring produces horizontal and vertical pressure to nut body, thereby the glue ring produces pressure to the nut body internal surface, in vibrations, can not become flexible after making nut screwing clamping, so the present invention need not extra special tool come nutting and can not become flexible because of vibrations behind the nut screwing clamping.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is an axial section structural representation of the present invention;
Fig. 2 is the structure sectional view of user mode of the present invention.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of lock nut of the present invention, comprise nut body 1, be provided with an antiratchetting groove 2 in the described nut body 1, be provided with a glue ring 3 and a pressure ring 4 in the described antiratchetting groove 2, pressure ring 4 is positioned at glue ring 3 outsides, be provided with first guiding surface 11 in the nut body 1, pressure ring 4 is provided with second guiding surface 41, the upper-end surface of glue ring 3 and lower end surface are respectively with first, two guiding surfaces 11,41 is suitable, when nut body is in user mode, between the inboard of described glue ring 3 and antiratchetting groove 2 and the pressure ring 4 and and screw rod 5 between be interference fit, glue ring 3 is extruded distortion and part is clamp-oned between the thread of screw rod 5 and between the thread of nut body 1, as shown in Figure 2, make cooperating between nut body 1 and the screw rod 5 produce very strong compressing power and frictional force, play locking effect.
Technique scheme also can have following improvement project: the outside of described antiratchetting groove 2 is provided with a fastening step 21.
In addition, the present invention is not limited to above-mentioned mode of execution, as long as it reaches technique effect of the present invention with essentially identical means, all should belong to protection scope of the present invention.
