Abstract
Description
Technical Field
[0001] This utility model relates to the field of screw technology, specifically to an anti-theft round-head Torx screw with a post. Background Technology
[0002] In today's society, screws, as an extremely common fastener, are widely used in many fields such as machinery, electrical appliances, buildings, and various public facilities. From assembling tables and chairs in daily life to constructing large equipment in industrial production, screws play a crucial role in connection and fastening.
[0003] The head design of common screws, such as slotted, Phillips, and even some simple hexagonal slots, makes them easily manipulated with common screwdrivers and wrenches. This means that in many situations, the connected components or equipment are at risk of being arbitrarily disassembled. In the field of public facilities, screws are widely used for assembly and fixing of devices such as streetlights, traffic lights, and surveillance cameras. Because conventional screws are easily disassembled, they pose a safety hazard.
[0004] In view of this, we propose a theft-proof round-head Torx screw with a post. Utility Model Content
[0005] The purpose of this invention is to provide an anti-theft round-head Torx screw with post, in order to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] An anti-theft round-head Torx screw with post includes a screw rod, a fixed screw head fixedly connected to the top of the screw rod, and a rotating screw head rotatably connected to the top surface of the fixed screw head. The rotating screw head has Torx grooves on its surface, and the fixed screw head has two pin slots on its surface. A rotating bolt is rotatably connected inside the rotating screw head, and a pin sleeve is threadedly connected to the side wall of the rotating bolt. The side wall of the pin sleeve is slidably connected to the inner wall of the pin slot, and an auxiliary sealing device is provided on one side of the rotating bolt.
[0008] When the screw needs to be fixed, the rotating bolt can be rotated, causing the threaded pin sleeve connected to the side wall of the rotating bolt to descend and slide into the pin groove. Then, the rotating screw head can be rotated through the swivel groove. When the rotating screw head rotates, the pin sleeve that has slid into the pin groove can drive the fixed screw head to rotate, thereby completing the screw fixing connection. After the fixing is completed, the rotating hole can be rotated to slide the pin sleeve out of the pin groove. After that, rotating the rotating screw head will not drive the fixed screw head and screw to rotate. This can prevent thieves who are not familiar with the screw structure from easily disassembling the screw, improve the safety of use, and reduce safety hazards.
[0009] Preferably, the auxiliary sealing device includes a rotating hole opened on the side wall of the rotating bolt, and a rotating threaded sleeve is rotatably connected to the inner wall of the rotating hole, and a sealing plate is fixedly connected to the side wall of the rotating threaded sleeve.
[0010] When the screw rod does not need to be disassembled, the sealing plate will cover and shield the plum blossom groove to prevent dust and rain from falling in. The sealing plate will also conceal the plum blossom groove, making it difficult to find and reducing the possibility of theft. When the screw rod needs to be disassembled, the sealing plate can be separated to the sides to expose the plum blossom groove for disassembly.
[0011] Preferably, the surface of the sealing plate has multiple strip grooves;
[0012] By setting the grooves, the surface roughness of the sealing plate is increased, the friction is increased, and the sealing plate is easier to move.
[0013] Preferably, the surface of the sealing plate has a perforated groove;
[0014] By setting a perforated groove, the perforated groove will provide two stretching positions, making it easy to separate the perforated groove to both sides.
[0015] Preferably, the surface of the pin sleeve is fixedly connected with multiple upper conical blocks;
[0016] By setting an upper conical block, the surface roughness of the pin sleeve is increased, thus increasing friction. When the pin sleeve is below the rotating bolt, the upper conical block will abut against the bottom surface of the rotating bolt, preventing it from easily loosening and improving ease of use.
[0017] Preferably, the bottom surface of the pin sleeve is fixedly connected with multiple lower conical blocks;
[0018] By setting a lower conical block, the roughness of the bottom surface of the pin sleeve is increased, thus increasing the friction. When the top of the lower conical block abuts against the bottom surface of the pin groove, the connection is more secure.
[0019] Preferably, a guide groove is provided at the top of the pin slot;
[0020] By setting a guide groove, the guide groove provides some simple guidance, making it easier for the rotating bolt to slide into the pin groove, reducing the difficulty of operation.
[0021] Preferably, a directional arrow is provided on one side of the pin slot, and the directional arrow is fixedly installed on the side wall of the fixing screw head;
[0022] By setting a directional arrow, the arrow will indicate the position of the pin slot, making it easy to slide the pin sleeve into the pin slot.
[0023] Compared with the prior art, the beneficial effects of this utility model are:
[0024] This type of anti-theft round-head Torx screw with post allows for easy fixing of the screw rod by rotating the rotating bolt. The rotating bolt causes the threaded pin sleeve on its side wall to slide down and into the pin groove. Then, rotating the rotating bolt head through the Torx groove causes the pin sleeve, which in turn slides into the pin groove, to rotate the fixing bolt head, thus completing the screw rod fixing connection. After fixing, rotating the rotating hole allows the pin sleeve to slide out of the pin groove. Afterward, rotating the rotating bolt head will not cause the fixing bolt head or screw rod to rotate, preventing thieves unfamiliar with the screw rod structure from easily disassembling it, improving security and reducing potential safety hazards.
[0025] This type of anti-theft round-head Torx screw with post has a sealing plate that covers and shields the Torx groove when the screw rod does not need to be disassembled, preventing dust and rain from falling in. The sealing plate also hides the Torx groove, making it difficult to spot and reducing the possibility of theft. When the screw rod needs to be disassembled, the sealing plate can be separated to the sides to expose the Torx groove for disassembly. Attached Figure Description

[0033] Please see Figure 1 - Figure 4 As shown, this utility model provides a technical solution:
[0034] An anti-theft round-head Torx screw with a post includes a screw rod 1. A fixed screw head 2 is fixedly connected to the top of the screw rod 1, and a rotating screw head 3 is rotatably connected to the top surface of the fixed screw head 2. The surface of the rotating screw head 3 has Torx grooves 4, and the surface of the fixed screw head 2 has two pin slots 5. A rotating bolt 6 is rotatably connected inside the rotating screw head 3, and a pin sleeve 7 is threadedly connected to the side wall of the rotating bolt 6. The side wall of the pin sleeve 7 is slidably connected to the inner wall of the pin slot 5, and an auxiliary sealing device is provided on one side of the rotating bolt 6. When it is necessary to fix the screw rod 1, the rotating bolt 6 can be rotated. The threaded pin sleeve 7 connected to the side wall of the rotating bolt 6 descends and slides into the pin groove 5. Then, the rotating head 3 is rotated through the plum blossom groove 4. When the rotating head 3 rotates, the pin sleeve 7, which has slid into the pin groove 5, can drive the fixed head 2 to rotate, thereby completing the fixed connection of the screw 1. After the fixation is completed, the rotating hole 8 can be rotated to slide the pin sleeve 7 out of the pin groove 5. After that, rotating the rotating head 3 will not be able to drive the fixed head 2 and the screw 1 to rotate. This can prevent thieves who are not familiar with the structure of the screw 1 from easily disassembling the screw 1, improve the safety of use, and reduce safety hazards.
[0035] In this embodiment, the auxiliary sealing device includes a rotating hole 8 opened on the side wall of the rotating bolt 6, and a rotating threaded sleeve 9 is rotatably connected to the inner wall of the rotating hole 8. A sealing plate 10 is fixedly connected to the side wall of the rotating threaded sleeve 9. When the bolt 1 does not need to be disassembled, the sealing plate 10 will cover and shield the plum blossom groove 4 to prevent dust and rain from falling. The sealing plate 10 will also cover and hide the plum blossom groove 4, so that the plum blossom groove 4 will not be easily discovered, reducing the possibility of theft. When the bolt 1 needs to be disassembled, the sealing plate 10 can be separated to both sides to expose the plum blossom groove 4 for disassembly.
[0036] In this embodiment, the surface of the sealing plate 10 is provided with a plurality of strip grooves 11; by providing the strip grooves 11, the surface roughness of the sealing plate 10 is enhanced, the friction is increased, and the sealing plate 10 is moved more easily.
[0037] In this embodiment, the surface of the sealing plate 10 is provided with a hollow groove 12; by providing the hollow groove 12, the hollow groove 12 will provide two stretching positions, which makes it easy to separate the hollow groove 12 to both sides.
[0038] In this embodiment, a plurality of upper conical blocks 13 are fixedly connected to the surface of the pin sleeve 7. By setting the upper conical blocks 13, the upper conical blocks 13 will increase the roughness of the surface of the pin sleeve 7 and increase the friction. When the pin sleeve 7 is below the rotating bolt 6, the upper conical blocks 13 will abut against the bottom surface of the rotating bolt 6 and will not easily loosen, thus improving the ease of use.
[0039] In this embodiment, a plurality of lower conical blocks 14 are fixedly connected to the bottom surface of the pin sleeve 7. By setting the lower conical blocks 14, the roughness of the bottom surface of the pin sleeve 7 is increased, and the friction is increased. When the top of the lower conical block 14 abuts against the bottom surface of the pin groove 5, the connection is more firmly fixed.
[0040] In this embodiment, a guide groove 15 is provided at the top of the pin groove 5; by setting the guide groove 15, the guide groove 15 will provide some simple guiding function, making it easier for the rotating bolt 6 to slide into the pin groove 5, reducing the difficulty of operation.
[0041] In this embodiment, a directional arrow 16 is provided on one side of the pin groove 5, and the directional arrow 16 is fixedly installed on the side wall of the fixing screw head 2; by setting the directional arrow 16, the directional arrow 16 will indicate the position of the pin groove 5, making it convenient to slide the pin sleeve 7 into the pin groove 5.
[0042] In this embodiment, an anti-theft round-head Torx screw with a pin is used to fix the screw 1. The rotating bolt 6 is rotated, causing the threaded insert 7 on the side wall of the rotating bolt 6 to slide down into the pin groove 5. Then, the rotating screw head 3 is rotated through the Torx groove 4. As the rotating screw head 3 rotates, the threaded insert 7 in the pin groove 5 drives the fixing screw head 2 to rotate, thus completing the fixing of the screw 1. After fixing, the rotating hole 8 can be rotated to slide the threaded insert 7 out of the pin groove 5. Afterward, rotating the rotating screw head 3 will not drive the fixing screw head 2 or the screw 1 to rotate. This prevents thieves unfamiliar with the screw 1 structure from easily disassembling the screw 1, improving safety and reducing potential security risks.
[0043] When the screw 1 does not need to be disassembled, the sealing plate 10 will cover and shield the plum blossom groove 4 to prevent dust and rain from falling. The sealing plate 10 will also cover and hide the plum blossom groove 4, making it difficult to find and reducing the possibility of theft. When the screw 1 needs to be disassembled, the sealing plate 10 can be separated to both sides to expose the plum blossom groove 4 for disassembly.
