[0002] Anti-theft screws are also called anti-disassembly screws. They are used to protect the interests of merchants. Merchants often use anti-theft screws on their products. Anti-theft screws play an anti-theft role. Anti-theft screws are used in many outdoor products because there are many disadvantages in management outdoors, and the use of anti-theft screws greatly reduces unnecessary losses. For example, anti-theft screws are widely used in outdoor guardrails. Anti-theft screws can be installed using special wrenches without special and complicated tools. Manufacturers will provide special tools to customers, so there is no need to worry about installation problems. Anti-theft screws are widely used in the field of power facilities, railway facilities, highway facilities, oil field facilities, urban lighting street lamp facilities, automobile tires and public fitness equipment, etc. The product performance is superior and has received extensive attention and praise from various industries in the society.

[0003] The Chinese patent publication (CN202020048330.9) discloses a detachable anti-theft screw device, which is provided with a rubber pad, which is beneficial to preventing wear on objects between the nut and the screw rod, making the anti-theft screw more secure when in use, and preventing loosening, making it more convenient to use. The protective sleeve is provided, which is beneficial to protecting the anti-theft screw, improving the anti-theft performance of the anti-theft screw when in use, and protecting objects. However, the application still has the following technical problems when in use: the existing anti-theft screws are mostly protected against theft by special-shaped flower grooves, but after the adaptation and adjustment of the disassembly wrench, the anti-theft screws still have the risk of being stolen, and the existing anti-theft screws have the risk of being forcibly disassembled;

[0004] In order to solve the above technical problems, a protective anti-theft screw is proposed. Utility Model Content

DETAILED DESCRIPTION

[0025] In the following, only some exemplary embodiments are briefly described. As those skilled in the art will appreciate, the described embodiments may be modified in various ways without departing from the spirit or scope of the present invention. Therefore, the drawings and descriptions are considered to be exemplary and non-restrictive in nature.

[0026] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, an embodiment of the utility model provides a protective anti-theft screw, which is composed of a main body mechanism 10 and a protective mechanism 20.

[0028] The main body mechanism 10 includes a screw rod 11, a connecting sleeve 14 and a fastening nut 13. During installation, the screw rod 11 cooperates with the fastening nut 13 to install the utility model at a specified position. The connecting sleeve 14 is sleeved on one end of the screw rod 11 and is used to connect the screw rod 11 to drive the screw rod 11 to rotate during disassembly. One side of the connecting sleeve 14 is rotatably connected to the screw rod 11. The fastening nut 13 is sleeved on one side of the screw rod 11. A matching fastening nut 13 is selected according to the size of the screw rod 11. The interior of the connecting sleeve 14 is symmetrically provided with slots 33. An inner side of the screw rod 11 is provided with a mounting hole 17. A magnetic block 18 is fixedly connected to an inner side of the mounting hole 17. The initial position of the metal plug block 19 is limited by the magnetic block 18 to prevent it from falling out of the mounting hole 17. The interior of the mounting hole 17 is symmetrically provided with metal plug blocks 19. The metal plug blocks 19 are made of an alloy material that can be adsorbed by the magnetic block 18, and the hardness thereof is the same as that of the screw rod 11.

[0029] In one embodiment, in order to enhance the movement stability of the metal plug 19 and limit its movable range, four slide grooves 31 are opened on one side of the inner part of the screw 11, and the slide grooves 31 are connected to the mounting holes 17. The inner part of the slide grooves 31 is slidably connected with a slider 32, and one side of the slider 32 is fixedly connected to the metal plug 19.

[0030] In one embodiment, in order to perform anti-corrosion treatment on the connection between the anti-pinch seat 21 and the screw rod 11, a waterproof gasket 23 is provided on one side of the anti-pinch seat 21, and a fixing gasket 12 for enhancing firmness is provided on one side of the fastening nut 13.

[0031] The protection mechanism 20 includes an anti-pinch seat 21 and a protective cover 22. The anti-pinch seat 21 is sleeved on one side of the screw rod 11 to protect the connecting sleeve 14 and prevent the connecting sleeve 14 from being violently removed. The protective cover 22 is sleeved on one side of the connecting sleeve 14 to cooperate with the anti-pinch seat 21 to fully surround the connecting sleeve 14 and prevent the connecting sleeve 14 from being directly rotated. The inner diameter of the anti-pinch seat 21 matches the outer diameter of the protective cover 22, so that after the anti-pinch seat 21 and the protective cover 22 are assembled with the connecting sleeve 14, their connection is in fit.

[0032] In one embodiment, in order to facilitate the connection between the protective cover 22 and the connecting sleeve 14 , a slot 15 is symmetrically provided on one side of the connecting sleeve 14 , a block 24 is clamped inside the slot 15 , and one side of the block 24 is fixedly connected to the protective cover 22 .

[0033] In one embodiment, in order to facilitate the assembly of the anti-pinch seat 21 and the connecting sleeve 14, and the anti-pinch seat 21 does not affect the rotation of the connecting sleeve 14, an annular groove 16 is opened on one side of the connecting sleeve 14, and a protrusion 25 is integrally formed on one side of the anti-pinch seat 21, and the protrusion 25 is rotatably connected to the connecting sleeve 14 through the annular groove 16.

[0034] When the utility model is in operation, the utility model is installed by fastening the nut 13 and cooperating with the screw rod 11, a fixing gasket 12 is arranged on one side of the contact surface of the fastening nut 13, and the anti-clip seat 21 is connected with the connecting sleeve 14 during installation, so that the protrusion 25 is inserted into the annular groove 16, and a waterproof gasket 23 is arranged on the contact surface of the anti-clip seat 21 to protect the screw rod 11 from rust, and the protective cover 22 is sleeved on one side of the connecting sleeve 14, so that it drives the card block 24 to be inserted into the card groove 15, and at the same time, the protective cover 22 is fitted with the anti-clip seat 21, and the magnetic block 18 absorbs the metal plug block 19 so that it does not contact the connecting sleeve 14, and does not drive the screw rod 11 to rotate when the connecting sleeve 14 rotates, so as to perform anti-theft protection. When disassembling, the protective cover 22 is removed, and the metal plug block 19 is absorbed by a device with stronger magnetism, so that it is disengaged from the mounting hole 17 and one side is inserted into the slot 33, and at this time, rotating the connecting sleeve 14 can drive the screw rod 11 to rotate, and the utility model is disassembled.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
