Description

A kind of stop nut
Technical field
It the utility model is related to a kind of technical field of nut, more particularly to a kind of stop nut.
Background technology
The locking problem of nut, it is always that people will solve the problems, such as in production, stop nut of the prior art has Many kinds, but be operation, structure or complex manufacturing mostly, high processing costs, it is not very practical.
Generally use bolts and nuts coordinate to lock parts, and bolt passes through and is connected to one with nut screw after parts Rise, realize being fixedly connected for parts.Because the long-time of parts uses, and can cause nut and bolted loosening, sends out Raw nut loosens out of gear mesh phenomenon from bolt.In order to prevent the loosening of nut, ordinary circumstance can be between nut and bolt Spring washer is set, and spring washer will apply certain elastic force to nut and withstand nut, and locking processing is carried out to nut so as to realize.But also deposit In weak point, that is, before nut is screwed on, spring washer is first covered on bolt, is so operated with just number It is tired, and still may be released by vibration for a long time.
Utility model content
Technical problem to be solved in the utility model is how to provide that a kind of structure and processing technology be simple, anti-loosening property Reliably, the stop nut and conveniently tightened.
The technical scheme that the utility model solves above-mentioned technical problem is as follows:
A kind of stop nut, including nut body, one end of the nut body is tilted to be provided with the first antiratchetting groove and The madial wall in the hole that two antiratchetting grooves, first antiratchetting groove and second antiratchetting groove run through inside the nut body Formed to the nut body inner recess, and first antiratchetting groove and second antiratchetting groove are oppositely arranged;The nut Body interior is provided with screwed hole, and the screw thread of the screwed hole is triangle thread, and its internal thread tooth form is set in tooth inclined-plane is become; The internal thread tooth form face of the screwed hole and the angle theta of axis2For 30 °.
Compared with prior art, the beneficial effects of the utility model are:The utility model product passes through in nut body one The inside at end sets the first antiratchetting groove and the second antiratchetting groove, and being pressurizeed downwards to the first antiratchetting groove and the second antiratchetting groove makes its deformation, When the locking skewed slot of stop nut deformation screws with bolt, internal thread insertion external threaded surface, taken off so as to effectively prevent nut Fall.At the same time the cusp of bolt thread is tightly withstood on the variable-tooth type tapered ramp of nut, so as to generate very big locking Power, caused locking frictional force also greatly increase;The utility model nut employs the variable-tooth type screw thread at 30 ° of angles, can make Obtain when it is screwed into bolt and more fasten, and it causes the anti-loose of nut with the first antiratchetting groove after deformation and the cooperation of the second antiratchetting groove It is better.
On the basis of above-mentioned technical proposal, the utility model can also do following improvement:
Further, the angle theta formed between first antiratchetting groove and second antiratchetting groove is obtuse angle.
It is using the above-mentioned further beneficial effect of scheme:The first antiratchetting groove and the second antiratchetting groove can be caused by buckling It is stronger with joint efforts to grabbing for bolt during shape, preferably lift the anti-loosing effect of the utility model stop nut.
Further, first antiratchetting groove and second antiratchetting groove are skewed slot, and positional symmetry is set.
It is using the above-mentioned further beneficial effect of scheme:First antiratchetting groove and the second antiratchetting groove into skewed slot and are symmetrical arranged Can more it facilitate, and compressive deformation more reasonable structure, it is more preferable with joint efforts to grabbing for bolt after deformation.
Further, the form of thread angle θ of the screwed hole1For 60 °.
It is using the above-mentioned further beneficial effect of scheme:It can cause when the utility model nut is screwed into bolt more It is convenient and more stable during fastening.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model nut preferred embodiment;
Fig. 2 is the structural representation of the utility model screw thread preferred embodiment;
Fig. 3 is the structural representation after the antiratchetting groove pressurizing and deformation of the utility model nut;
Fig. 4 is the structure top view of the utility model nut preferred embodiment.
In accompanying drawing, the list of parts representated by each label is as follows:
1st, nut body, the 2, first antiratchetting groove, the 3, second antiratchetting groove, 4, screwed hole.
Embodiment
Principle of the present utility model and feature are described below in conjunction with accompanying drawing, example is served only for explaining this practicality It is new, it is not intended to limit the scope of the utility model.
It should be noted that triangle thread:Tooth form cross-sectional area is shaped as the screw thread of triangle.Internal thread:Position exists Screw thread in threaded female body;Internal thread tooth form face:Internal thread is in the face of tooth form bottom;Form of thread angle:It is adjacent on form of thread Angle between two tooth sides.
As shown in Figure 1, 2, a kind of stop nut, including nut body 1, one end of the nut body 1 is tilted to be provided with First antiratchetting groove 2 and the second antiratchetting groove 3, first antiratchetting groove 2 and second antiratchetting groove 3 are in the nut body 1 The madial wall in the hole that face is run through is formed to the inner recess of nut body 1, and first antiratchetting groove 2 and described second locking Groove 3 is oppositely arranged;The nut body 1 is internally threaded hole 4, and the screw thread of the screwed hole 4 is triangle thread, and in it Form of thread is set in tooth inclined-plane is become.As shown in figure 3, by setting the first antiratchetting groove 2 and the in the inside of the one end of nut body 1 Two antiratchetting grooves 3, make its deformation to the first antiratchetting groove 2 and the second pressurization downwards of antiratchetting groove 3, when the locking skewed slot of stop nut deformation When being screwed with bolt, internal thread insertion external threaded surface, come off so as to effectively prevent nut.At the same time the cusp of bolt thread Tightly withstand on the variable-tooth type tapered ramp of nut, so as to generate very big coupling mechanism force, caused locking frictional force is also big Big increase.
Preferably, the angle theta formed between first antiratchetting groove 2 and second antiratchetting groove 3 is obtuse angle.It can cause First antiratchetting groove 2 and the second antiratchetting groove 3 are stronger with joint efforts to grabbing for bolt in compressive deformation, preferably lift the utility model spiral shell The anti-loosing effect of bolt.
As shown in Fig. 2 the internal thread tooth form face of the screwed hole 4 and the angle theta of axis2For 30 °.The utility model nut The variable-tooth type screw thread at 30 ° of angles is employed, it can be caused more to be fastened when being screwed into bolt, and itself and the first antiratchetting groove 2 after deformation Cause the anti-loosing effect of nut more preferably with the cooperation of the second antiratchetting groove 3.
Preferably, first antiratchetting groove 2 and second antiratchetting groove 3 are skewed slot, and positional symmetry is set, and is so set Putting more to facilitate, and compressive deformation more reasonable structure, more preferable with joint efforts to grabbing for bolt after deformation.
Preferably, the form of thread angle θ of the screwed hole 41For 60 °, the utility model nut can be caused to be screwed into bolt Shi Gengjia is convenient, and more stable during fastening.
Preferred embodiment of the present utility model is the foregoing is only, it is all in this practicality not to limit the utility model Within new spirit and principle, any modification, equivalent substitution and improvements made etc., guarantor of the present utility model should be included in Within the scope of shield.
