Abstract
The utility model discloses an antitheft nut which comprises an outer shell and a fastening body located inside the outer shell, wherein fastening threads are formed on the inner wall of the fastening body, a ratchet is arranged on the outer wall of the fastening body, a non-return detent is arranged on the inner wall of the outer shell, the ratchet is connected with the non-return detent in a meshed mode, an inner groove is formed at the bottom of the outer shell, an outer groove is formed at the bottom of the fastening body, the inner groove and the outer groove are communicated to form a hollow cavity, the outer shell is fixedly connected with the fastening body through a rigidity insuring clip, and the rigidity insuring clip is located inside the hollow cavity. According to the antitheft nut, one-way rotation of the outer shell and the fastening body is achieved through the meshed connection of the non-return detent of the outer shell and the ratchet of the fastening body, and then the nut can not be detached after the nut is enabled to be installed and fixed through the fastening threads, antitheft performance of items is greatly improved, and the antitheft nut is simple in structure and convenient to manufacture and install.
Description
Technical field
The utility model relates to fastener areas, relates in particular to a kind of anti-theft nut.
Background technique
Known anti-theft nut pattern is a lot, and it is in the majority with what removably connect, and non-removable and anti-theft effect preferably anti-theft nut often processing technology is complicated, assembly parts is more so that cost is higher or it is complicated to install.
The model utility content
Technical problem to be solved in the utility model is to provide a kind of effectively antitheft and simple in structure, anti-theft nut of being convenient to install.For solving the problems of the technologies described above, the utility model by the following technical solutions:
A kind of anti-theft nut comprises shell and the fastener that is positioned at shell, and described fastener inwall is provided with binding thread; Described fastener outer wall is provided with ratchet, and described outer casing inner wall is provided with non-return ratchet, and described ratchet is meshed with described non-return ratchet; Described outer casing bottom is provided with an inner groovy, described fastener bottom is provided with an outer groove, described inner groovy and outer groove are communicated with and form a cavity, and described shell is fixedly connected with by a rigidity insurance clamp with fastener, and described rigidity insurance clamp is positioned at described cavity.
Preferably, described cross-sectional outer is a regular hexagon.
This anti-theft nut is realized the single direction rotation of shell and fastening piece by the engagement of the non-return ratchet of shell and fastener ratchet, and then it is fixing rear non-dismountable that this nut is installed by binding thread, and then greatly improved the theftproof performance of article, and this anti-theft nut simple in structure, be convenient to make and install.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the worm's eye view of Fig. 1.
Embodiment
Further illustrate embodiment of the present utility model below in conjunction with accompanying drawing.
See Fig. 1, a kind of anti-theft nut that the utility model relates to comprises shell 1 and the fastener 2 that is positioned at shell 1, and described fastener 2 inwalls are provided with binding thread; See Fig. 2, described fastener 2 outer walls are provided with ratchet 21, and described shell 1 inwall is provided with non-return ratchet 11, and described ratchet 21 is meshed with described non-return ratchet 11; See Fig. 3, described shell 1 bottom is provided with an inner groovy 12, described fastener 2 bottoms are provided with an outer groove 22, described inner groovy 12 and outer groove 22 are communicated with and form a cavity 3, described shell 1 is fixedly connected with by a rigidity insurance clamp 4 with fastener 2, and described rigidity insurance clamp 4 is positioned at described cavity 3.Preferably, described shell 1 cross section is a regular hexagon.
In this anti-theft nut, described non-return ratchet 11 is meshed with ratchet 21, and then make shell 1 can only do unidirectional rotation round fastener 2, in the present embodiment, shell 1 can only be done counterclockwise rotation around fastener 2, and drive fastener 2 and rotate together, and meet the sense of rotation of tightening nut, thereby reach the purpose that tightens the screw.During with the reverse stubborn shell 1 of instrument, fastener 2 does not rotate, and shell 1 skids, thereby has played the effect of Anti-dismantling, has greatly improved the anti-theft capability of article.
This anti-theft nut is a kind of non-removable anti-theft nut, is applicable to the long-term fixing fastening piece of implementing antitheft.It is the same unrestricted with the nut of regular screw threads in application, and its application is very extensive, as: the facility of electric power facility, rail facility, expressway, field facility, city lighting street lamp facility, and public fitness equipments etc.So long as the article that fix with bolt and nut, for preventing all can being used technique and product by the dismounting of non-original idea.Can fill non-removable characteristics because it has, thus its effectively prevent stolen and lose, thereby strengthened management and the protection of public facilities and equipment, strengthen the antitheft coefficient of national communal facility, reduce the loss of country.The present invention can use the installing of the door and window protective gratings such as family, retail shop, factory, and reduces national loss.In addition, this anti-theft nut is fit to the lead screw of various regular screw threads, and general tool can be installed, and is simple to operate.
