Technical Field

[0001] The utility model relates to the technical field of fasteners, in particular to a safety bolt. Background Art

[0002] As a common mechanical connector, bolts are widely used in various fields, from daily furniture assembly to precision electronic equipment, to large industrial machinery and transportation vehicles. The basic function of bolts is to fasten two or more parts together to ensure the stability and functionality of the structure.

[0003] However, with the development of society and the advancement of technology, the requirements for bolts are no longer limited to simple fastening functions. Especially in some high-value, high-risk or security-sensitive fields, such as aerospace, defense and military, nuclear energy facilities, financial safes and high-end electronic equipment, the safety of bolts has become a crucial consideration.

[0004] During use, traditional bolts are at risk of being disassembled by unauthorized personnel, which may cause damage to equipment, data leakage, and even endanger public safety. The key is that these traditional bolts are disassembled and reinstalled by relevant personnel, which is not easy for relevant staff to find, so it is difficult to take timely remedial measures afterwards.

[0005] In view of the above technical problems, it is necessary to design a safety bolt that can leave obvious instructions when someone tries to disassemble it or disassemble it and then install it again, so that relevant staff can find it in time and take corresponding measures, thereby improving the safety of the entire system. Utility Model Content

[0006] The utility model provides a safety bolt, which solves the above problems existing in the use process of the prior art.

[0007] The technical solution of the utility model is achieved as follows: a safety bolt, characterized in that it includes a bolt head, a screw rod and a fragile component, the bolt head and the screw rod are integrally formed, the bolt head includes a cylinder, at least two rotating ribs are circumferentially arranged on the outer wall of the cylinder, one end of the rotating rib is integrally formed on the cylinder, the rotating rib includes a clockwise rotating surface and a counterclockwise rotating surface, the fragile component includes a ring and a fragile plate fixedly connected to the ring, the ring is sleeved on the screw rod and located at the lower side of the bolt head, the number of the fragile plates is the same as that of the rotating ribs, each of the fragile plates is correspondingly fitted on the counterclockwise rotating surface of each of the rotating ribs, and the fragile plates cover the counterclockwise rotating surface.

[0008] Preferably, the fragile plate extends from bottom to top in a wave shape.

[0009] Preferably, side sealing plates are integrally formed on both sides of the fragile plate.

[0010] Preferably, the collar is also integrally formed with limit blocks having the same number as the fragile plates, and each of the limit blocks is correspondingly attached to the lower side of the clockwise rotating surface of each of the rotating ribs.

[0011] Preferably, a signature area is provided on the ring.

[0012] Preferably, the collar is provided with an identification number.

[0013] Preferably, the outer side wall of the cylinder and the rotating rib are coated with indicator paint on a side away from the cylinder.

[0014] Preferably, the collar is adhered to the underside of the bolt head, and the fragile plate is adhered to the counter-clockwise rotating surface.

[0015] In summary, the beneficial effects of the present invention are:

[0016] 1. The utility model is provided with a fragile component, which is sleeved on the screw rod through a collar and is located at the lower side of the bolt head, and a fragile plate is integrally formed on the collar and fits on the counterclockwise rotating surface of each rotating rib. When the user rotates the screw rod clockwise to tighten it through the clockwise rotating surface of the rotating rib, the fragile plate will not be damaged. When the screw rod needs to be loosened by counterclockwise rotation, it is necessary to press the counterclockwise rotating surface, which will damage the fragile plate covering the counterclockwise rotating surface. Therefore, relevant staff only need to observe the integrity of the fragile component to know whether someone has tried to disassemble it or reinstall it after disassembly. The damage of the fragile component will leave obvious indications, so that relevant staff can find out in time and take corresponding measures, thereby improving the safety of the entire system.

DETAILED DESCRIPTION

[0022] The following will be combined with the attached embodiment of the present utility model Figure 1-3 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] like Figure 1 to Figure 2 As shown, the utility model discloses a safety bolt, including a bolt head 1, a screw rod 2 and a fragile component, wherein the bolt head 1 and the screw rod 2 are integrally formed, wherein the bolt head 1 includes a cylinder 11, and at least two rotating ribs 12 are circumferentially arranged on the outer wall of the cylinder 11, and one end of the rotating rib 12 is integrally formed on the cylinder 11, and the rotating rib 12 includes a clockwise rotating surface 121 and a counterclockwise rotating surface 122, the so-called clockwise rotating surface 121 is the surface to be contacted when the bolt head 1 and the screw rod 2 are rotated clockwise by the rotating rib 12, and the so-called counterclockwise rotating surface 122 is the surface to be contacted when the bolt head 1 and the screw rod 2 are rotated counterclockwise by the rotating rib 12, and the screw rod 2 of the utility model is tightened by clockwise rotation and loosened by counterclockwise rotation. In the present invention, the fragile component includes a collar 31 and a fragile plate 32 fixedly connected to the collar 31. The collar 31 is sleeved on the screw 2 and is located at the lower side of the bolt head 1. The number of the fragile plates 32 is the same as that of the rotating ribs 12. Each fragile plate 32 is correspondingly fitted on the counter-clockwise rotating surface 122 of each rotating rib 12. The fragile plates 32 cover the counter-clockwise rotating surface 122. The fragile plates 32 are made of a material that is easy to crack or break when subjected to the expected stress, such as ceramics, glass, thin metal sheets, and some very brittle plastics. The collar 31 can be made of a different material or the same material as the fragile plate 32, but if they are made of the same material, they need to be thickened and strengthened. The collar 31 needs to be able to withstand being pressed between the bolt head 1 and the connected part without being damaged.

[0025] The working principle of the utility model is as follows: when the user rotates the screw 2 clockwise to tighten it by rotating the clockwise rotating surface 121 of the rotating rib 12, the fragile plate 32 will not be damaged. When the screw 2 needs to be loosened by rotating it counterclockwise, it is necessary to press the counterclockwise rotating surface 122, which will damage the fragile plate 32 covering the counterclockwise rotating surface 122. Therefore, the relevant staff only needs to observe the integrity of the fragile component to know whether someone has tried to disassemble it or disassemble it and then reinstall it. The damage of the fragile component will leave obvious indications, so that the relevant staff can find it in time and take corresponding measures, thereby improving the safety of the entire system.

[0026] In addition, Figure 3 As shown, it is a tool for twisting the utility model, which has a handle 41, a stopper 42 and a latching tooth 43 for forming abutment with each rotating rib 12. It can be used to rotate the utility model clockwise, and rotating the utility model counterclockwise will also damage the fragile plate 32.

[0027] Furthermore, the fragile plate 32 extends from bottom to top in a wave shape, so that the uneven fragile plate 32 is more likely to break due to other objects pressing on its surface. In addition, side blocking plates 33 are integrally formed on both sides of the fragile plate 32, because holes will be left on both sides between the wavy fragile plate 32 and the rotating rib 12, and the blocking plates 33 are used to block the holes to prevent relevant personnel from using the holes to loosen the utility model.

[0028] In the present invention, the collar 31 is also integrally formed with the same number of limit blocks 34 as the fragile plates 32, and each limit block 34 is correspondingly fitted to the lower side of the clockwise rotating surface 121 of each rotating rib 12, because the collar 31 is pressed between the bolt head 1 and the surface of the object to be connected by the screw 2, but once the screw 2 is loosened due to long-term use, then the relevant personnel have the opportunity to first rotate the fragile component and turn the fragile plate 32 away from the counterclockwise rotating surface 122, so that the counterclockwise rotating surface 122 can be directly contacted to apply force without damaging the fragile plate 32. Therefore, by setting the limit blocks 34, even if the screw 2 is loosened to a certain extent, there is no way to rotate the fragile component. In addition, in order to further prevent the relevant personnel from rotating the fragile component, the collar 31 can be glued to the lower side of the bolt head 1, and the fragile plate 32 can be glued to the counterclockwise rotating surface 122.

[0029] In order to prevent the relevant personnel from replacing the new fragile component after loosening and disassembling the utility model by destroying the fragile plate 32, and then tightening the utility model, while the relevant staff cannot do so, a signature area 35 is provided on the collar 31. The signature area 35 is used to sign the name of the person in charge, so that the relevant staff can detect whether the fragile component has been replaced based on the signature in the signature area 35. Furthermore, an identification number 36 is also provided on the collar 31. The identification number 36 of each fragile component is different, which will increase the difficulty for the relevant personnel to replace it with other fragile components. Of course, the identification number 36 can also be replaced with an anti-counterfeiting mark or the like.

[0030] In addition, in order to prevent relevant personnel from clamping the cylinder 11 or the rotating rib 12 on the side away from the cylinder 11 with tools and then forcibly rotating the utility model (generally such an operation requires a lot of force), the outer wall of the cylinder 11 and the rotating rib 12 on the side away from the cylinder 11 are coated with indicator paint 13. The indicator paint 13 is a prior art, and the bonding force between it and the bolt head 1 is weak, so when it is clamped with a large force, the paint is easy to fall off, so that it is easy for the staff to detect whether someone has twisted the utility model.

[0031] It should also be pointed out that the terms used in the present invention, such as "front", "rear", "vertical", "horizontal", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only used to facilitate the description of the present invention and simplify the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
