Problems solved by technology
[0003] In order to overcome the disadvantages of the existing lock nuts that the knurled pins are easy to fall off, resulting in inability to lock or get stuck, and the plug sleeve is easy to pollute the environment, the present invention provides a bracket type non-plug sleeve roller anti-theft nut. The knurled pin of the roller anti-theft nut is not easy to fall off, easy to install, and there is no plug sleeve, which will not pollute the environment

Embodiment Construction
[0013] The present invention will be further described below in conjunction with accompanying drawing:
[0014] Depend on Figure 1 to Figure 3 As shown, a bracket type non-plug sleeve roller anti-theft nut includes a nut 1, and the inner wall of the nut 1 is provided with at least one wedge groove 5 with an arc-shaped cross section. One end of the arc is tangent to the inner wall of the nut, and the other end is Connect with the inner wall of the nut through a straight edge. When the number of wedge grooves 5 is greater than 1, the wedge grooves 5 are evenly distributed along the circumferential direction. The inner wall of the nut 1 on the top of the wedge groove 5 has a ring groove 3, and the bottom of the ring groove 3 communicates with the top of the wedge groove 5. The ring groove 3 has a built-in support 2 of non-metallic material. The support 2 is flexible and can be conveniently used. installed in the ring groove 3. The upper part of the bracket 2 is a circular rin...

The invention relates to a support frame type plug-sleeve-free roller theftproof screw nut, which mainly solves the problems that a knurled pin of the existing locking screw nut can easily fall off to cause the locking or clamping incapability, and a plug sleeve can easily pollute the environment. 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 [0001] The invention relates to the field of machinery, in particular to a bracket type anti-theft roller nut without a plug sleeve. Background technique [0002] At present, the commonly used radial locking anti-unloading and anti-theft fasteners generally use plug sleeves and self-adhesives to seal the knurled pin in the wedge groove. When in use, the plug sleeve is pushed out by the bolt and the knurled pin stays in the wedge groove. , when the nut is tightened, the knurled pin rolls to the bottom of the wedge groove to play a locking role. Because the wedge groove has a certain width, when the plug sleeve is ejected, the knurled pin is easy to fall off or lie horizontally in the wedge groove, causing the bolt to fail to prevent loosening and anti-theft after tightening or to be stuck before tightening. Simultaneously because the plug sleeve belongs to the refractory substance, it will cause environmental pollution if it is not cleaned up in time after ea...
