Abstract
The utility model discloses an anti-theft nut assembly, which comprises a nut body and a nut key, wherein the nut body is provided with a standard threaded hole in the axial direction of the nut body; a rotating outer buckle is arranged on the outer surface of the nut body; a clamping head matched with a standard tool is arranged at one end of the nut key; a clamping sleeve matched with the nut body is arranged at the other end of the nut key; and a rotating inner buckle matched with the rotating outer buckle is arranged on the inner surface of the clamping sleeve. The anti-theft nut has a simple structure; and the nut body can be detached by the nut key, so that a wheel can be effectively prevented from being stolen.
Description
Technical field
The utility model relates to field of mechanical technique, is specifically related to a kind of anti-theft nut component.
Background technique
Existing wheel is by wheel hub clamping bolt or nut it to be installed on the wheel axle, nut that is adopted or bolt are standard piece, be hex head bolt or hexagon nut, utilize conventional tool (for example spanner) easily the bolt or the nut of stationary hub to be dismantled, therefore, automobile tire is often therefore stolen.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of anti-theft nut component, under the prerequisite that makes things convenient for the wheel hub dismounting, can prevent effectively that wheel is stolen.
For achieving the above object, the utility model adopts following technological scheme:
Anti-theft nut component, comprise nut body and nut key, it axially offers the standard thread hole described nut body upper edge, described nut body outer surface is provided with the outer button of rotation, described nut key one end is provided with the dop with the conventional tool coupling, the other end then is provided with the cutting ferrule with described nut body coupling, and the internal surface of described cutting ferrule is provided with to buckle in the matching rotation outward with described rotation and buckles.
The outer button of described rotation is for being positioned at described nut body outer surface along its at least one fin that axially is provided with, in the described rotation button for be arranged on described cutting ferrule internal surface along described nut key extend axially and with at least one catching groove of described fin form fit.
Described nut cross-under on the key has a lanyard.
The anti-theft nut component that the utility model is set forth, its beneficial effect is:
Simple in structure, under prerequisite, just can dismantle nut body with nut key, prevent that effectively wheel is stolen.
Description of drawings
Fig. 1 is the structural representation of a kind of anti-theft nut component of the utility model.
Embodiment
Below, in conjunction with the accompanying drawings and embodiment, anti-theft nut component of the present utility model is described further, so that clearerly understand the utility model technological thought required for protection.
As shown in Figure 1, be a kind of anti-theft nut component of the present utility model, comprise nut body 1 and nut key 2, it is cylindric that nut body 1 is substantially, offer a standard thread hole 11 thereon vertically, be used for the bolt socket with standard, the nut body outer surface axially is evenly distributed with a plurality of fins 12 along it.It is cylindric that nut key 2 is substantially, be provided with the hexagonal dop 21 that mates with the standard spanner at the one end, but the other end is the cutting ferrule of spiral-lock in nut body 1 outside, the external diameter of the internal diameter of cutting ferrule and nut body 1 is suitable, cutting ferrule is interior along a plurality of catching grooves 22 of axially being provided with of nut key 2, the shape of catching groove 22 and fin 12 couplings, these a plurality of catching grooves 22 and a plurality of fins 12 are plug-in mounting one to one; In addition, on nut key 2, go back cross-under one lanyard 23 is arranged.
During use, the end that nut key 2 is had a catching groove 22 is sleeved on fin 12 outsides on the nut body 1, and spanner is buckled in hexagonal dop 21 outsides, and swivel nut key 2 then can drive nut body 1 and rotate, with nut body 1 fastening or dismounting.After nut body 1 is installed, take away nut key 2, then conventional tool can't fasten with nut body 1, thereby can not dismantle nut body 1 easily.
Certainly, according to common practise, above-mentioned fin and catching groove can be one group one to one, as long as after guaranteeing that it fastens, can be used in the rotational freedom that limits between nut body and the nut key, make its two can rotate synchronously and get final product; Also can be on nut body, to process catching groove, process fin on the key at nut.
For a person skilled in the art, can make other various corresponding changes and distortion, and these all changes and distortion should belong within the protection domain of the utility model claim all according to technological scheme described above and design.
