Technical Field

[0001] This utility model relates to the field of bolt technology, and in particular to an anti-theft bolt. Background Technology

[0002] A bolt is a mechanical part, a type of fastener consisting of a head and a thread. It needs to be used with a nut to fasten two parts with through holes. There are many types of bolts, with different head shapes and sizes, as well as different materials and performance grades, depending on the application. Common bolt head shapes include hexagonal head, round head, and square head.

[0003] Traditional bolts have a simple structure, making them easy to install and remove. They lack anti-theft features, allowing criminals to easily remove them without special tools. This increases the risk of bolts and related equipment being stolen, which not only affects production efficiency but also increases downtime and maintenance costs. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the above-mentioned equipment cannot be prevented from being stolen during use, resulting in reduced production efficiency and additional economic losses, and thus proposes an anti-theft bolt.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an anti-theft bolt, comprising a screw rod, a set of circular grooves on the top of the screw rod, a connecting rod fixedly installed on the top of the screw rod, a cylinder movably fitted on the outer wall of the connecting rod, with the bottom of the cylinder contacting the top of the screw rod, a sliding groove I on the outer wall of the cylinder, two movable grooves on the outer wall of the cylinder, two sliding grooves II on the outer wall of the cylinder, an installation groove on the top of the cylinder, a set of circular holes on the bottom of the inner wall of the cylinder, and a spring I fixedly installed on the bottom of the inner wall of the cylinder.

[0006] Preferably, a top plate is fixedly installed on the top of the spring, and the outer wall of the top plate is movably inserted into the inside of the mounting groove.

[0007] Preferably, the outer wall of the top plate has two positioning grooves, and a nut is fixedly installed on the top of the top plate.

[0008] Preferably, a set of positioning rods is fixedly installed at the bottom of the top plate, and two locking blocks are fixedly installed at the bottom of the inner wall of the mounting groove.

[0009] Preferably, a circular ring is fixedly inserted into the inner wall of the mounting groove, and a spring is fixedly installed on one side of the inner wall of each of the two movable grooves.

[0010] Preferably, a magnetic block is fixedly installed on one side of the outer wall of each of the two springs, and the outer walls of the two magnetic blocks are movably inserted into the interior of the movable slot.

[0011] Preferably, a baffle is fixedly installed on one side of the outer wall of each of the two magnetic blocks, and the outer walls of the two baffles are movably inserted into the interior of the movable groove, and two sliders are movably inserted into the inner wall of the first sliding groove.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, such as Figures 1-4 As shown, this utility model provides an anti-theft bolt, including a screw 1, a set of circular grooves 2 on the top of the screw 1, a connecting rod 3 fixedly installed on the top of the screw 1, a cylinder 4 movably sleeved on the outer wall of the connecting rod 3, and the bottom of the cylinder 4 contacting the top of the screw 1, a sliding groove 5 on the outer wall of the cylinder 4, two movable grooves 6 on the outer wall of the cylinder 4, two sliding grooves 7 on the outer wall of the cylinder 4, an installation groove 8 on the top of the cylinder 4, a set of circular holes 9 on the bottom of the inner wall of the cylinder 4, a spring 10 fixedly installed on the bottom of the inner wall of the cylinder 4, a top plate 11 fixedly installed on the top of the spring 10, and the outer wall of the top plate 11 movably inserted into the installation groove 8, two positioning grooves 12 on the outer wall of the top plate 11, a nut 13 fixedly installed on the top of the top plate 11, a set of positioning rods 14 fixedly installed on the bottom of the top plate 11, and two locking blocks 15 fixedly installed on the bottom of the inner wall of the installation groove 8.

[0025] The effect achieved by the entire embodiment 1 is that if a thief directly tightens the nut 13, the nut 13 will only tighten the spring 10 and cannot move the screw 1 below. When the staff wants to remove the bolt, they can first press the nut 13 downward, so that the nut 13 moves the top plate 11 below. At this time, the locking block 15 will be inserted into the positioning groove 12 on the top plate 11, so that the locking block 15, the nut 13, the top plate 11 and the cylinder 4 become a whole. Then, the cylinder 4 needs to be rotated by the nut 13 so that the circular groove 2 is aligned with the circular hole 9. At this time, the user can press the nut 13 again so that the positioning rod 14 is inserted into the circular groove 2 and the circular hole 9. Finally, the screw 1 can be rotated by rotating the nut 13. When using this bolt, it is necessary to assemble all the parts together, which effectively confuses the thief and reduces the loss of the bolt and related equipment.

[0026] Example 2, as Figures 2-4 As shown, a ring 16 is fixedly inserted into the inner wall of the mounting groove 8. Spring 17 is fixedly installed on one side of the inner wall of each of the two movable grooves 6. Magnetic blocks 18 are fixedly installed on one side of the outer wall of each of the two springs 17, and the outer walls of the two magnetic blocks 18 are movably inserted into the interior of the movable groove 6. Baffles 19 are fixedly installed on one side of the outer wall of each of the two magnetic blocks 18, and the outer walls of the two baffles 19 are movably inserted into the interior of the movable groove 6. Two sliders 20 are movably inserted into the inner wall of the slide groove 5. A protective sleeve 21 is fixedly installed between the outer walls of the two sliders 20, and the outer wall of the cylinder 4 is movably inserted into the interior of the protective sleeve 21.

[0027] The effect achieved by the entire embodiment 2 is that when a thief tries to unscrew the bolt, the outer protective cover 21 can drive the slider 20 to slide inside the first groove 5, thus preventing the bolt from being unscrewed and achieving the anti-theft effect. When the user needs to rotate the bolt, he can first bring the outer electromagnet close to the protective cover 21. At this time, the magnetic force generated by the electromagnet can attract the magnetic block 18 to move towards the electromagnet and slide and compress the second spring 17 inside the movable groove 6. At this time, the magnetic block 18 drives the baffle 19 to move together. When the user rotates the slider 20 to below the second groove 7, he can pull the protective cover 21, so that the slider 20 passes through the first groove 5, the movable groove 6 and the second groove 7, making it convenient for people to remove the protective cover 21. After use, the protective cover 21 can be put back on, so that the bolt can be reused and the cost of bolt replacement is reduced.

[0028] Working principle: When faced with an attempt by a thief to illegally loosen the bolt, the bolt uses the outer protective sleeve 21 to drive the slider 20 to slide within the first groove 5, effectively preventing the bolt from being easily unscrewed. For legitimate users, simply bringing the outer electromagnet close to the protective sleeve 21 will attract the magnetic block 18 to slide along the movable groove 6, compressing the second spring 17 in the process. The movement of the magnetic block 18 will synchronously drive the baffle 19 to move. Then, the user only needs to rotate the slider 20 to below the second groove 7 to easily pull the protective sleeve 21, allowing the slider 20 to smoothly pass through the first groove 5, the movable groove 6, and the second groove 7, achieving convenient removal of the protective sleeve 21. After use, the protective sleeve 21 can be replaced, facilitating the reuse of the bolt and greatly reducing the cost of bolt replacement. Even if a thief violently damages the protective sleeve 21, The bolt cannot be removed by unscrewing the nut 13. The nut 13 can only cause a slight deformation of the spring 10, but cannot drive the screw 1 below to move. This further enhances the anti-theft performance of the bolt. When the bolt needs to be removed, the staff only needs to press the nut 13 down slightly to move the top plate 11 together. At this time, the locking block 15 will be precisely inserted into the positioning groove 12 on the top plate 11, thus firmly connecting the locking block 15, the nut 13, the top plate 11 and the cylinder 4 into a whole. Then, the staff rotates the nut 13 to drive the cylinder 4 to rotate until the circular groove 2 and the circular hole 9 are precisely aligned. At this time, press the nut 13 again, and the positioning rod 14 will be smoothly inserted into the circular groove 2 and the circular hole 9. Finally, the staff only needs to rotate the nut 13 to drive the screw 1 to rotate together, so as to achieve convenient removal of the bolt.

[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
