Detailed Description

The following describes embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 is the utility model relates to a schematic diagram of conical antitheft nut embodiment, fig. 2 is the utility model relates to a top view of conical antitheft nut embodiment, fig. 3 is the utility model relates to a side view of conical antitheft nut embodiment, as shown in the figure, the utility model provides a conical antitheft nut, including body 1, body 1 includes first portion 2 and second portion 3, and first portion 2 and second portion 3 are the non-detachable structure of an organic whole suppression, and the height of first portion 2 and the height of second portion 3 equal. The first part 2 is in a cone frustum shape, the second part 3 is in a cylinder frustum shape, and the diameter of the upper end face of the first part 2 is smaller than that of the lower end face of the second part 3. The integrated structure of the cone table and the cylinder table ensures that the body 1 cannot find the acting point by using common and conventional tools, and cannot rotate, thereby playing the anti-theft effect.

A through hole 6 and a through hole 6 penetrating through the upper end face 4 and the lower end face 5 are arranged in the body 1 and are circular threaded holes, and the body 1 is screwed on the matched bolts through the through hole 6. Through-hole 6 is equipped with first internal thread 7 on the surface, is equipped with external screw thread 8 on the outer wall of second portion 3, and first internal thread 7 is the same with the direction of rotation of external screw thread 8, further screws first internal thread 7 after screwing external screw thread 8, realizes the fastening connection of body 1 rather than assorted bolt.

Fig. 4 is a schematic diagram of the mounting tool of the embodiment of the cone-shaped anti-theft nut of the present invention, as shown in the figure, the body 1 is matched with the special mounting tool 9, the second internal thread 11 matched with the external thread 8 is arranged in the mounting head 10 of the mounting tool 9, the second internal thread 11 and the external thread 8 are screwed to drive the body 1 to rotate continuously, and the first internal thread 7 of the body 1 is further screwed to fasten the body on the matched bolt. The second internal thread 11 is matched with the external thread 8, so that the mounting tool 9 cannot slip during working, force is conveniently applied, and the mounting is easy. After the body 1 is installed, the second internal thread 11 is unscrewed, so that the installation tool 9 is detached, the first internal thread 7 and the bolt are not unscrewed, and an anti-theft effect is achieved. The mounting head 10 is connected with a handle 12, the handle 12 and the mounting head 10 have a certain inclination angle, after the mounting head 10 is sleeved on the body 1, the tail part of the handle 12 is lifted upwards, and the body 1 is fastened or detached more conveniently and easily and flexibly. The handle 12 is provided with a hanging hole 13 at one end far away from the mounting head 10, which is convenient for storage.

The upper end surface 4 of the first part 2 is provided with a dismounting groove 14, the depth of the dismounting groove 14 is changed from deep to shallow along the screwing direction of the body 1, and the body 1 can be unscrewed forcibly along the opposite screwing direction of the body 1 by using a special dismounting tool, thereby dismounting the body. The lower end face 5 of the second part 3 is provided with a convex edge 15, the convex edge 15 can play a role in sealing, and meanwhile, the gasket can be used as a gasket, so that the cost is saved.

The specific implementation mode is as follows: when the mounting tool is used, firstly, the body 1 is screwed on the matched bolt, then the mounting head 10 of the mounting tool 9 is sleeved on the body 1, finally, the handle 12 is rotated, the second internal thread 11 and the external thread 8 are screwed to drive the body 1 to continue rotating, the first internal thread 7 of the body 1 is further screwed to fasten the body 1 on the bolt, then, the handle 12 is rotated reversely, the second internal thread 11 and the external thread 8 of the mounting head 10 are unscrewed and the mounting tool 9 is dismounted, and the mounting is finished. When in disassembly, the body 1 is unscrewed and disassembled by using a special disassembling tool to apply force at the disassembling groove 14. After the body 1 is installed, the body cannot be detached by using a common tool, so that the anti-theft effect is achieved.

Therefore, the utility model adopts the above structure a tapered antitheft nut, simple structure, simple to operate is easy, has improved fastening efficiency, and the flexible operation is with low costs, and the practicality is good, and the instrument among the prior art can't fix and rotate the nut after the fastening, reaches the purpose of theftproof.

Finally, it should be noted that: the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting the same, and although the present invention is described in detail with reference to the preferred embodiments, those skilled in the art should understand that: the technical solution of the present invention can still be modified or replaced by other equivalent means, and the modified technical solution can not be separated from the spirit and scope of the technical solution of the present invention.
