The support frame type plug-sleeve-free roller theftproof screw nut is characterized in that at least one wedge groove (5) with the arc-shaped cross section is formed in the inner wall of a screw nut (1); an annular groove (3) is formed in the inner wall of the screw nut (1) arranged at the upper part of the wedge groove (5); the bottom of the annular groove (3) communicates with the top of the wedge groove (5); a support frame (2) made of non-metallic materials is built in the annular groove (3); the upper part of the support frame (2) is a circular ring (6); the bottom of the circular ring (6) is connected with at least one group of support claws (9); the circular ring (6) is arranged in the annular groove; the support claws (9) are arranged in the wedge groove (5); the number of the support claws (9) in each group is two; in addition, a pin groove (8) is arranged between the two support claws (9); a cylindrical knurled pin (4) is built in each pin groove (8). The support frame type plug-sleeve-free roller theftproof screw nut has the advantages that the falling cannot easily occur; the installation is convenient; no plug sleeve exists; the environment pollution is avoided.
Description
Technical field
The present invention relates to mechanical field, specifically a kind of stent-type is without plug sleeve roller anti-theft screw nut.
Background technology
Knurled pin is typically enclosed in wedge by the anti-anti-theft fastening piece that unloads of conventional radial direction locking at present using plug sleeve and adhesive sticker more
In groove, plug sleeve is bolted ejection when in use and knurled pin is stayed in wedge groove, and when the nut 34 is tightened, knurled pin rolls to wedge trench bottom
Play a part of locking.Because wedge groove has certain width, when plug sleeve is ejected, knurled pin is easy to fall off or horizontal in wedge groove,
Bolt is caused anti-loose anti-theft effect not to be had after tightening or is just stuck before not tightening.Simultaneously because plug sleeve belongs to difficult degradation thing
Matter, if cleaning can cause environmental pollution not in time after the completion of each use.
The content of the invention
In order to overcome, the knurled pin of existing locking nut is easy to fall off to be caused to lock or stuck, plug sleeve easily pollutes environment
Deficiency, the present invention provides a kind of stent-type without plug sleeve roller anti-theft screw nut, rolling of the stent-type without plug sleeve roller anti-theft screw nut
Cost is difficult for drop-off, easy for installation, and without plug sleeve, does not pollute the environment.
The technical scheme is that：A kind of stent-type is without plug sleeve roller anti-theft screw nut, including nut, the nut inner wall
On be provided with the wedge groove that at least one section is arc, be provided with annular groove on the nut inner wall on wedge groove top, and annular groove bottom and wedge groove
Top communicates, and the annular groove is built-in with the support of nonmetallic materials, and the frame upper is annulus, and annulus bottom is connected with least
One group of support claw, wherein annulus is placed in annular groove, and support claw is placed in wedge groove, and every group of support claw is two, and two support claws
Between be provided with cotter way, cotter way is built-in with the knurled pin of cylinder.
The wedge groove is 2, and the support claw is two groups.
The side of support claw is fixed with flexure strip on the support.
The annulus external diameter of the support be less than the big footpath of annular groove, internal radius be less than nut inner thread path, and annulus thickness
Height of the degree less than annular groove；, less than the height of wedge groove, the height of the flexure strip is less than support claw for the height of the support claw
Highly.
The present invention has the advantages that：Due to taking such scheme, nut inner wall is provided with wedge groove and annular groove, in annular groove
Support is equipped with, is coordinated by the wedge groove of support and arc, knurled pin is fixed in wedge groove with support so that nut is using preceding
Knurled pin is difficult for drop-off, knurled pin upset is prevented from when using and is come off, and prevents unloading anti-theft function so as to play.Support is after use
Closure is in nut, it is not necessary to remove, so as to avoid polluting environment.

Specific embodiment
The invention will be further described below in conjunction with the accompanying drawings：
As shown in Fig. 1 to Fig. 3, a kind of stent-type is provided with without plug sleeve roller anti-theft screw nut, including nut 1 on the inwall of the nut 1
At least one section is the wedge groove 5 of arc, and one end of arc is tangent with nut inner wall, and the other end is connected with nut inner wall by straight flange
Connect.When the quantity of wedge groove 5 is more than 1, wedge groove 5 is evenly distributed.Annular groove 3 is provided with the inwall of nut 1 on the top of wedge groove 5, and
The bottom of annular groove 3 communicates with the top of wedge groove 5, and the annular groove 3 is built-in with the support 2 of nonmetallic materials, and support 2 is flexible, Ke Yifang
Being installed in annular groove 3 just.The top of the support 2 is annulus 6, and the bottom of annulus 6 is connected with least one set of support claw 9, wherein round
Ring 6 is placed in annular groove 3, and to be provided with cotter way 8 between two, and two support claws 9, cotter way 8 is built-in with cylinder to every group of support claw 9
The knurled pin 4 of shape, i.e., two support claws 9 constitute a unit with cost 4, and said units are placed in wedge groove 5, the number of the unit
Amount is consistent with the quantity of wedge groove 5.The side of support claw 9 can also be fixed with flexure strip 7 on the support 2, and flexure strip 7 can make
Knurled pin 4 occupy the centre position of wedge groove 5.
The external diameter of annulus 6 of the support 2 is less than the big footpath of annular groove 3, and the internal diameter of annulus 6 is less than the internal thread path of nut 1, and annulus
Height of 6 thickness less than annular groove 3；The height of the support claw 9 is less than the height of wedge groove 5, and the height of the flexure strip 7 is less than
The height of support claw 9.Simultaneously cotter way 8 with diameter greater than or equal to knurled pin 4 diameter, knurled pin 4 is placed into cotter way 8
It is interior.
When the nut is combined：Support 2 is put into annular groove 3 and wedge groove 5 first, then knurled pin 4 is encased in the pin of support 2
In groove 8, such knurled pin 4 is just enclosed between support 2 and nut 1.During using the stent-type without plug sleeve roller anti-theft screw nut,
From the nut with bolt same size, wedge groove 5 is screwed into inwardly annular groove 3 outwardly；When 1 dextrorotation of nut, knurled pin 4 is bolted
External screw thread drives and slided toward the recess of wedge groove 5 and relative skidding.When 1 unscrewed of nut, bolt external screw thread drive support 2 invert or
Flexure strip 7 reversely promotes support 2, while support 2 drives knurled pin 4 to be slided toward the sharp corner of wedge groove 5, so that bolts and nuts 1
Locking, when the coupling mechanism force of the bigger generation of unscrewed power is also bigger.Once locking, artificially cannot in the case where nut 1 is not destroyed
Unloaded, play and good anti-unload anti-theft feature.
