Description

Technical Field

[0001] The utility model relates to a bolt, in particular to an anti-disassembly and anti-dropping bolt, belonging to the technical field of hardware tool design and manufacturing. Background Art

[0002] A bolt is a cylindrical fastener with threads, also often called a screw. It can be used directly in mechanical equipment and can be used with nuts. Traditional bolts are made of metal as a whole, and when in use, they are directly locked with nuts or parts using threads. However, traditional bolts are often used on parts that often move or vibrate. Bolts are prone to loosening and falling off after long-term use, and in some occasions where anti-dismantling is required, ordinary bolts have no anti-dismantling capabilities at all. At present, there are many non-standard anti-dismantling bolts on the market, which are not only complex in structure, production and processing, assembly and use, but also have non-standard structures that greatly reduce their applicability. Therefore, it is necessary to improve the existing technology. Summary of the invention

[0003] In order to solve the problems of complex structure, complex production and processing, complex assembly and use of existing anti-dismantling bolts, the utility model provides an anti-dismantling and anti-falling bolt.

[0004] The utility model is completed through the following technical scheme: an anti-disassembly and anti-detachment bolt, including a screw rod and a screw head arranged at one end of the screw rod, characterized in that a connecting rod with a notch is arranged at the other end of the screw rod, and a rotating clamping block is hinged in the notch, so that after the bolt is screwed with a nut or the bolt is screwed with a screw hole of a part, the rotating clamping block is rotated to a state perpendicular to the screw rod, thereby preventing the nut from detaching from the bolt or the bolt from detaching from the screw hole through the rotating clamping block, thereby achieving the purpose of preventing the bolt from being disassembled and anti-detached.

[0005] The connecting rod is set as a short straight rod with a diameter smaller than the screw rod. The short straight rod is coaxially connected to the screw rod. The groove is opened along the axial direction of the connecting rod and is set as a through groove with open openings on three sides to prevent the connecting rod with a small diameter from obstructing the nut or screw hole.

[0006] The rotating block is configured as a rectangular block, which is inserted into the slot of the connecting rod. A rotating shaft is inserted into the center of the rectangular block, and both ends of the rotating shaft are connected to the connecting rod walls on both sides of the slot so that the rotating block can rotate in the slot.

[0007] The width of the rotating block is less than or equal to the outer diameter of the connecting rod, and the length of the rotating block is greater than the outer diameter of the screw, so that when the rotating block is rotated to be coaxial with the screw, it can avoid obstruction to the nut or the screw hole, and when the rotating block is rotated to be perpendicular to the screw, it can prevent the nut from detaching from the screw or the screw from detaching from the screw hole.

[0008] The utility model has the following advantages and effects: adopting the above scheme, after the bolt is screwed with the nut or the bolt is screwed with the screw hole of the part, the rotating block is rotated to a state perpendicular to the screw rod, so that the nut is prevented from being separated from the bolt or the bolt is prevented from being separated from the screw hole by the rotating block, thereby achieving the purpose of preventing the bolt from being disassembled and falling off. The simple structure can bring convenience to the use and production of the bolt, and can be applied to standard bolts of any specifications. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] The following will be combined with the drawings in the embodiments of the utility model to 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 the embodiments. 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. Example

[0012] The utility model provides an anti-disassembly and anti-slip bolt, comprising a screw rod 2, a screw head 1 arranged at one end of the screw rod 2, a connecting rod 3 with a notch arranged at the other end of the screw rod 2, a rotating clamp block 4 hinged in the notch, so that after the bolt is screwed with the nut or the bolt is screwed with the screw hole of the part, the rotating clamp block 4 is rotated to a state perpendicular to the screw rod 2, so that the nut is prevented from being separated from the screw rod 2 or the screw 2 is prevented from being separated from the screw hole by the rotating clamp block 4, thereby achieving the purpose of preventing the bolt from being disassembled and anti-slipped;

[0013] The connecting rod 3 is a short straight rod with a diameter smaller than that of the screw rod 2. The short straight rod is coaxially connected to the screw rod 2. The notch is provided along the axial direction of the connecting rod 3 and is provided as a through slot with three open sides, so as to prevent the connecting rod 3 with a small diameter from obstructing the nut or the screw hole.

[0014] The rotating block 4 is set as a rectangular block, which is inserted into the slot of the connecting rod 3. A rotating shaft 5 is inserted in the center of the rectangular block. The two ends of the rotating shaft 5 are connected to the walls of the connecting rod 3 on both sides of the slot, so that the rotating block 4 can rotate in the slot.

[0015] The width of the rotating block 4 is less than or equal to the outer diameter of the connecting rod 3, and the length of the rotating block 4 is greater than the outer diameter of the screw 2, so that when the rotating block 4 is rotated to be coaxial with the screw 2, it can avoid obstruction to the nut or the screw hole. When the rotating block 4 is rotated to be perpendicular to the screw 2, it can prevent the nut from detaching from the screw 2 or the screw 2 from detaching from the screw hole.
