Abstract
The utility model discloses a cold-proof high-temperature-resistant anti-theft nut. A radial C-shaped groove (6) is arranged on the inner wall of a threaded hole of a nut body (2). The bottom face of the C-shaped groove (6) is provided with a protrusion (5) higher than the bottom face of the C-shaped groove (6). The protrusion (5) is connected with the nut body (2) into a whole. A spring (4) and a steel ball (3) are arranged in the C-shaped groove (6) and on one side of the protrusion (5) in the screw-in direction. The spring (4) is arranged between the steel ball (3) and the protrusion (5). When a bolt reaches the C-shaped groove (6), threads of the bolt drive the steel ball (3) to compress the spring (4) so as to enable the steel ball (3) to be located at a low position without influencing screw-in of the nut body (2). When the nut body (2) is screwed out reversely, the steel ball (3) is located at a high position under the elastic function of the spring (4) to prevent the nut body (2) from being screwed out and play an anti-theft role. The cold-proof high-temperature-resistant anti-theft nut cannot be screwed out whether in cold winter or a burning situation, and can always play the anti-theft role.
Description
Technical field
The utility model relates to a kind of anti-theft nut, especially a kind of winter protection, high temperature resistant anti-theft nut.
Background technique
At present, be fixed with the rubber spring block with glue in " C " shape groove of commercially available anti-theft nut, namely be equivalent to " projection " of the present utility model.The rubber spring block is understood the hardening embrittlement in the winter of cold, the turn nut of exerting oneself, and the rubber spring block can become fragment, thereby makes nut lose anti-theft function; The rubber spring block run into that high temperature makes can deliquescing, can make equally nut lose anti-theft function.Therefore, designing a kind of winter protection, high temperature resistant anti-theft nut, is the present technical issues that need to address.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of winter protection, high temperature resistant anti-theft nut.
The technical scheme in the invention for solving the technical problem is:
Winter protection, high temperature resistant anti-theft nut, inwall at the tapped hole of nut is provided with radially " C " shape groove, groove bottom at " C " shape groove has the projection that exceeds groove bottom, projection is connected as a single entity with nut, in " C " shape groove, be provided with spring and steel ball, spring and steel ball are in protruding precession direction one side, spring is between steel ball and projection, and when bolt arrived " C " shape groove place, the screw thread of bolt drove the steel ball Compress Spring, make steel ball be in low level, do not affect the precession of nut, when nut oppositely screwed out, steel ball was in a high position under the elastic force effect of spring, stop the back-out of nut, play anti-theft function.
Preferably, be set with plug in the tapped hole of nut, when on the nut precession bolt, bolt progressively ejects plug, the convenient installation.
Preferably, described projection is that nut outer cylinder at " C " shape groove place inwardly is stamped to form.
The sectional shape of described projection is circle, rectangle or triangle.
Compared with prior art, the utility model is in the winter of cold or in the situation elder generation that burns without human relations, all can not screw out, and can play anti-theft function all the time; Owing to be provided with plug, form easily complete sets of products again, not only be convenient to manage, and convenient the installation.
Description of drawings
Fig. 1 is the plan view (sectional view) of structural representation of the present utility model;
Fig. 2 is that the A-A of Fig. 1 is to sectional drawing.
Embodiment
As shown in the figure, winter protection, high temperature resistant anti-theft nut, inwall at the tapped hole of nut 2 is provided with radially " C " shape groove 6, groove bottom at " C " shape groove 6 has the projection 5 that exceeds groove bottom, projection 5 is connected as a single entity with nut 2, be provided with spring 4 and steel ball 3 in " C " shape groove 6, spring 4 and steel ball 3 are in protruding 5 precession directions, one side, and spring 4 is between steel ball 3 and projection 5, when bolt arrives " C " shape groove 6 place, the screw thread of bolt drives steel ball 3 Compress Springs 4, makes steel ball 3 be in low level, does not affect the precession of nut 2, when nut 2 oppositely screws out, steel ball 3 is in a high position under the elastic force effect of spring 4, stop the back-out of nut 2, plays anti-theft function.
Be set with plug 1 in the tapped hole of nut 2, when on the nut 2 precession bolts, bolt progressively ejects plug 1.
Described protruding 5 is that nut outer cylinder at " C " shape groove 6 places inwardly is stamped to form.
Described protruding 5 sectional shape is circle, rectangle or triangle.
