Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

An anti-theft bolt as shown in the attached fig. 1-4, mainly comprising a bolt body 1, a nut 2, an extension cap 3, an anti-theft cap 4, a convex strip 5, an elastic component 6, a locking rod 7 and a locking groove 8, wherein:

the elastic member 6 includes a fixing groove 601, a compression spring 602, and a moving plate 603;

bolt body 1, nut 2, extension cap 3 and theftproof cap 4 have played the effect of support as the carrier, and sand grip 5 and elastic component 6 are used for making 7 locks of locking pole in the inside of locking groove 8, improve bolt body 1's theftproof effect, and locking pole 7 and locking groove 8 are used for the theftproof cap 4 card in bolt body 1's one end to improve bolt body 1's theftproof effect.

As shown in fig. 2 and fig. 4, the elastic assembly 6 includes a fixing groove 601 formed inside the protruding strip 5, a compression spring 602 is fixedly connected to an inner wall of the fixing groove 601, a moving plate 603 is fixedly connected to one end of the compression spring 602, one side of the moving plate 603 is fixedly connected to the locking rods 7, and one ends of the two locking rods 7 penetrate through the protruding strip 5;

in order to enable the locking rod 7 to be clamped inside the locking groove 8, the bolt body 1 is prevented from being stolen, when the locking rod 7 slides to be aligned with the locking groove 8, the movable plate 603 is pushed to slide through the elastic force of the compression spring 602, the sliding of the movable plate 603 pushes the locking rod 7 to slide inside the locking groove 8, and therefore the anti-theft cap 4 is clamped on one side of the nut 2, and the anti-theft effect on the bolt body 1 is achieved.

Wherein, as shown in fig. 2 and fig. 4, spacing groove 9 has all been seted up to the top and the bottom of fixed slot 601 inner wall, the equal fixedly connected with stopper 10 in the upper and lower both sides of movable plate 603, the equal sliding connection in spacing groove 9 of the not relative one end of two stopper 10 is in the inside of spacing groove 9, so that drive stopper 10 and slide in the inside of spacing groove 9 through the gliding while of movable plate 603, play spacing effect through stopper 10 and spacing groove 9 to locking lever 7, avoid locking lever 7 to rock at gliding in-process.

Wherein, as shown in fig. 1 and fig. 3, the arc wall 11 that matches with sand grip 5 is all seted up on the both sides surface of extension cap 3, and the equal sliding connection of the one end of two sand grips 5 and locking pole 7 is in the inside of arc wall 11, and the one end and the locking groove 8 of arc wall 11 are linked together to be convenient for slide through the arc wall 11 that sets up sand grip 5 and locking pole 7.

Wherein, as shown in figure 1, the inside of theftproof cap 4 is equipped with two buckles 12, and draw-in groove 13 has all been seted up on the both sides surface of nut 2, and two equal interference fit of buckle 12 are in the inside of draw-in groove 13 to in the inside of draw-in groove 13 through buckle 12 interference fit, thereby strengthened the theftproof cap joint on the nut, make the theftproof cap need just can open through professional instrument.

As shown in fig. 3, a cross groove 14 is formed in a surface of one side of the extension cap 3, and anti-slip textures are formed on an inner wall of the cross groove 14, so that an anti-slip effect is increased by the anti-slip textures.

The working principle of the utility model is as follows: when the anti-theft bolt is used, the locking rod 7 is extruded, the locking rod 7 and the convex strips 5 slide in the arc-shaped groove 11, when the locking rod 7 slides to be aligned with the locking groove 8, the movable plate 603 is pushed to slide by the elastic force of the compression spring 602, the locking rod 7 is pushed to slide in the locking groove 8 by the sliding of the movable plate 603, the movable plate 603 drives the limit block 10 to slide in the limit groove 9 while sliding, the locking rod 7 is limited by the limit block 10 and the limit groove 9, the locking rod 7 is prevented from shaking in the sliding process, so that the anti-theft cap 4 is clamped at one side of the nut 2, the anti-theft effect on the bolt body 1 is realized, meanwhile, the anti-theft cap is clamped on the nut by the interference fit of the buckle 12 in the clamping groove 13, the anti-theft cap can be opened only by a professional tool, and protective textures in the cross groove 14 are used, the anti-skidding effect when dismantling bolt body 1 has been played, has increased the frictional force between instrument and the bolt body 1, prevents the effect of skidding.
