Technical Field
[0001] The utility model relates to the technical field of screws, in particular to a screw that is anti-disassembly. Background Art
[0002] Screws are common mechanical connectors, usually used to fix two or more components together. They are usually made of metal, with a threaded exterior and a head at one end, and can be screwed in or out by rotation. Due to their convenient disassembly characteristics, when used in some devices, they may also be convenient for criminals to disassemble, resulting in damage or theft of the devices and causing property losses. In view of this, the utility model proposes a screw that is anti-disassembly. Summary of the Utility Model
[0003] The purpose of the utility model is to address the problem in the background art that the convenient disassembly characteristic of screws may be convenient for criminals to disassemble, resulting in damage or theft of the devices and causing property losses, and to propose a screw that is anti-disassembly.
[0004] The technical solution of the utility model: An anti-disassembly screw, comprising a threaded rod and a screw head fixedly connected to one side of the threaded rod; a rotating mechanism arranged on the threaded rod for driving the threaded rod to rotate; and a synchronization component installed in the threaded rod to facilitate the disassembly of the rotating mechanism.
[0005] Optionally, the rotating mechanism includes a groove, a connecting groove, a connecting rod, and a rotating block. The groove is opened on the side of the threaded rod away from the screw head, the connecting groove is opened at the center position of the groove, the connecting rod is threadedly connected to the connecting groove, and the rotating block is fixedly connected to the end of the connecting rod away from the threaded rod.
[0006] Optionally, the rotating mechanism further includes a mounting groove opened at the center position on the side of the rotating block away from the threaded rod.
[0007] Optionally, the synchronization component includes a rotating cylinder, a moving cylinder, a connecting plate, a gear, and an internal gear ring. The rotating cylinder is rotatably connected to the rotating block, the moving cylinder is threadedly connected to the inside of the rotating cylinder, the connecting plate is fixedly connected to the bottom of the moving cylinder, the gear arranged in the groove is installed at the bottom of the connecting plate, the internal gear ring is installed in the groove, and the internal gear ring cooperates with the gear.
[0008] Optionally, the synchronization component further includes multiple groups of limit posts installed on the side of the rotating block close to the threaded rod. The multiple groups of limit posts are arranged at equal intervals, and the gear is slidably connected to the multiple groups of limit posts.
[0009] Optionally, the synchronization component further includes a sliding groove, a rotating rod, and a pushing plate. The sliding groove, which is fan-shaped, is formed in the rotating block and is disposed on the outer ring of the rotating cylinder. The rotating rod slidably connected to the sliding groove is fixedly connected to the outer ring of the rotating cylinder, and the pushing plate is installed at one end of the rotating rod away from the rotating cylinder.
[0010] Optionally, the installation groove is hexagonal, cross-shaped, or straight-shaped.
[0011] Compared with the prior art, the present utility model has the following beneficial technical effects:
[0012] With the setting of the connecting rod in the present utility model, when the rotating block is rotated, the connecting rod can be driven to be threadedly connected into the connecting groove. Until the rotating block contacts the threaded rod, further rotation of the rotating block can drive the threaded rod to continue rotating. When using a tool to rotate the rotating block through the installation groove, the threaded rod and the screw head can be driven to rotate to achieve the fastening effect. When the rotating block is rotated in the reverse direction, the rotating block can be made to move away from the threaded rod, making it difficult to disassemble the threaded rod and the screw head.
[0013] Furthermore, after rotating the rotating block and driving the threaded rod to rotate and tighten, it may cause the connection between the connecting rod and the connecting groove to be too tight. As a result, when the rotating block is rotated in the reverse direction, the screw head may be driven to loosen, making the fixing effect worse. With the setting of the synchronization component, when the rotating block is rotated, the gear can be driven to rotate through the limiting column, and then the internal gear ring can be driven to rotate, thereby driving the threaded rod and the screw head to rotate and tighten. This avoids the tight connection between the connecting rod and the connecting groove, so that the disassembly of the rotating block will not affect the fixing effect of the threaded rod and the screw head, ensuring the tightness of the screw during fixing.
[0014] In summary, the present utility model is convenient for locking and fixing, while ensuring tightness and being not easy to disassemble, with high safety and avoiding damage to property. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Embodiment
[0029] Such as Figure 1As shown in the figure, a screw with anti-disassembly function proposed by the utility model includes a threaded rod 1 and a screw head 2 fixedly connected to one side of the threaded rod 1. The threaded rod 1 and the screw head 2 rotate synchronously. After the screw head 2 is connected with a nut in a matching manner, a fastening function is realized.
[0030] Specifically, please refer to Figure 2 and Figure 3 The above-mentioned screw includes a rotating mechanism 3 arranged on the threaded rod 1 for driving the threaded rod 1 to rotate. The rotating mechanism 3 includes a groove 31, a connecting groove 32, a connecting rod 33, and a rotating block 34. The groove 31 is opened on the side of the threaded rod 1 away from the screw head 2. The connecting groove 32 is opened at the central position of the groove 31. The connecting rod 33 is threadedly connected to the connecting groove 32. The connecting rod 33 is connected to the connecting groove 32 after rotation. The rotating block 34 is fixedly connected to the end of the connecting rod 33 away from the threaded rod 1. The rotating block 34 and the connecting rod 33 rotate synchronously. The rotating mechanism 3 further includes a mounting groove 35 opened at the central position on the side of the rotating block 34 away from the threaded rod 1, which is used to rotate the rotating block 34 through a tool, so as to drive the connecting rod 33 to be threadedly connected to the connecting groove 32. Then, when the rotating block 34 is rotated continuously, the threaded rod 1 can be driven to rotate, so that the screw head 2 rotates and is threadedly connected to the nut to realize the fastening function. The mounting groove 35 is set in a hexagonal, cross-shaped or linear shape. The shape of the mounting groove 35 is not limited here, and it can be set into different shapes according to different tools.
[0031] Furthermore, as shown in Figure 2-4As shown, the above-mentioned screw further includes a synchronization component 4 installed in the threaded rod 1 to facilitate the disassembly of the rotating mechanism 3. After the connecting rod 33 is threadedly connected to the connecting groove 32, it is possible that the rotating block 34 drives the threaded rod 1 to rotate by driving the connecting rod 33, and a relatively large force still needs to be applied to rotate the rotating block 34 after the screw head 2 is threadedly connected to the nut to ensure the tight fit between the screw head 2 and the nut. As a result, the connection between the connecting rod 33 and the connecting groove 32 may be too tight, and when disassembling the connecting rod 33, the groove 31 may be driven to rotate synchronously, causing the nut to loosen. Therefore, the synchronization component 4 is proposed. The synchronization component 4 includes a rotating cylinder 41, a moving cylinder 42, a connecting plate 43, a gear 44, and an internal gear ring 45. The rotating cylinder 41 is rotatably connected to the rotating block 34, and the rotating cylinder 41 rotates in place. The moving cylinder 42 is threadedly connected to the inside of the rotating cylinder 41, and the moving cylinder 42 drives the rotating cylinder 41 to move towards the threaded rod 1 when rotating. The connecting plate 43 is fixedly connected to the bottom of the moving cylinder 42, and the moving cylinder 42 drives the connecting plate 43 to move synchronously when moving. The gear 44 disposed in the groove 31 is installed at the bottom of the connecting plate 43, and the gear 44 moves synchronously with the connecting plate 43. The internal gear ring 45 is installed in the groove 31, and the position of the internal gear ring 45 is fixed. And the internal gear ring 45 cooperates with the gear 44. When the gear 44 moves to the outer ring of the internal gear ring 45, the gear 44 drives the threaded rod 1 to rotate through the internal gear ring 45 when rotating. The synchronization component 4 further includes a plurality of sets of limit posts 46 installed on the side of the rotating block 34 close to the threaded rod 1. The plurality of sets of limit posts 46 are arranged at equal intervals, and the gear 44 is slidably connected to the plurality of sets of limit posts 46. The limit posts 46 limit the movement of the gear 44, so that the rotating cylinder 41 cannot drive the moving cylinder 42 to rotate when rotating, but can only drive the moving cylinder 42 to move. The synchronization component 4 further includes a chute 47, a rotating rod 48, and a push plate 49. The fan-shaped chute 47 is opened in the rotating block 34, and the chute 47 is arranged on the outer ring of the rotating cylinder 41. The rotating rod 48 slidably connected to the chute 47 is fixedly connected to the outer ring of the rotating cylinder 41, and the rotating rod 48 drives the rotating cylinder 41 to rotate when sliding. The push plate 49 is installed at the end of the rotating rod 48 away from the rotating cylinder 41 to facilitate pushing the rotating rod 48 to rotate.
[0032] In this embodiment, during installation, first align the position of the connecting rod 33 with the connecting groove 32. Rotate the rotating block 34 while inserting the connecting rod 33 into the connecting groove 32. At this time, when rotating the rotating block 34, the connecting rod 33 is threadedly connected to the connecting groove 32. As the rotating block 34 rotates, one side of the rotating block 34 contacts the threaded rod 1. At this time, rotate the rotating block 34 to make the rotating block 34 slightly move away from the threaded rod 1, and at the same time push the push plate 49, so that the rotating rod 48 drives the rotating cylinder 41 to rotate. The rotating cylinder 41 drives the moving cylinder 42 to move towards the side close to the threaded rod 1. The moving cylinder 42 drives the gear 44 to move synchronously through the connecting plate 43, and under the limiting action of the limiting column 46, it moves smoothly and does not rotate. At this time, while rotating the rotating block 34 to adjust the distance between the rotating block 34 and the threaded rod 1, while pushing the push plate 49, until the gear 44 moves to the outer ring of the internal gear ring 45 and is stuck on the outside of the internal gear ring 45. At this time, rotating the rotating block 34 drives the threaded rod 1 to rotate through the action of the gear 44 and the internal gear ring 45, rather than driving the threaded rod 1 to rotate by rotating the connecting rod 33. At the same time, the connecting rod 33 can fix the rotating block 34 on the side of the threaded rod 1 to prevent the rotating block 34 from accidentally falling off. At this time, insert a tool into the installation groove 35 and drive the rotating block 34 to rotate. When the rotating block 34 rotates, multiple limiting columns 46 rotate synchronously, so that the gear 44 rotates and drives the internal gear ring 45 to rotate, so that the threaded rod 1 rotates synchronously and drives the screw head 2 to rotate, tightening the screw head 2. Then push the push plate 49 to move back to its original position, so that the rotating cylinder 41 rotates to drive the moving cylinder 42 to move, so that the gear 44 moves away from the outside of the internal gear ring 45. At this time, when rotating the rotating block 34 in the reverse direction, since the screw head 2 is fixed tightly, when the rotating block 34 rotates, it drives the connecting rod 33 to disengage from the connecting groove 32 and does not drive the threaded rod 1 to rotate, making the rotating block 34 move away from the threaded rod 1. At this time, the threaded rod 1 and the screw head 2 are not easy to disassemble.
[0033] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
