Description

Technical Field

[0001] The utility model relates to the technical field of bolt fasteners, in particular to a combined bolt fastener with anti-slipping threads. Background Technique

[0002] A bolt is a cylindrical threaded fastener that mates with a nut. A type of fastener consisting of two parts, a head and a screw rod, which needs to cooperate with a nut for firmly connecting two parts with through holes. Bolts are usually used as mechanical parts and are a relatively common connecting fastener.

[0003] Currently, bolts and gaskets are generally of independent structures. When in use, the gasket is first sleeved on the bolt, and then the bolt is screwed into the fastened part.

[0004] However, existing gaskets are generally relatively thin and not easy to pick up. When the gasket is sleeved on the bolt, it is also prone to falling off during subsequent fastening operations, resulting in a reduction in work efficiency. Moreover, if the bolt is forcibly rotated at an incorrect angle, the phenomenon of slipping threads will occur. Therefore, it does not meet the existing requirements, and for this reason, we propose a combined bolt fastener with anti-slipping threads. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined bolt fastener with anti-slipping threads to solve the problems in the above background technique, such as existing gaskets being generally relatively thin and not easy to pick up, the gasket being prone to falling off during subsequent fastening operations, resulting in a reduction in work efficiency, and if the bolt is forcibly rotated at an incorrect angle, the phenomenon of slipping threads will occur, etc.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A combined bolt fastener with anti-slipping threads, including a screw rod, an installation column is installed on the upper end surface of the screw rod, a bolt head is arranged above the screw rod, an installation groove is arranged on the lower end surface of the bolt head, the installation groove and the installation column are movably connected through an installation mechanism, the installation mechanism includes an L-shaped plate, the L-shaped plate is limited by a fixing mechanism, a gasket is arranged above the outer surface of the screw rod, a vertical rod is fixedly installed on the lower end surface of the screw rod, and a correction mechanism is installed on both sides of the vertical rod. The correction mechanism includes a rotating shaft, the rotating shaft is arranged on both sides of the outer surface of the vertical rod through a groove, and a rotating plate is sleeved on the outer surface of the rotating shaft.

[0007] Preferably, the L-shaped plate is arranged before and after the upper end surface of the bolt head through a transverse groove, the L-shaped plate is movably connected with the inner wall of the transverse groove through a spring A, a clamping block is installed on the lower side of the opposite side of the outer surface of the two L-shaped plates, and clamping grooves are arranged on both sides of the outer surface of the installation column.

[0008] Preferably, the transverse groove is connected to the installation groove through a through groove, the clamping block penetrates through the through groove, and the clamping block is adapted to the clamping groove.

[0009] Preferably, the fixing mechanism includes a cross bar, the cross bar is arranged on the front and rear end faces of the bolt head through a vertical groove, an outer sleeve plate is sleeved on the outer surface of the cross bar, and the outer sleeve plate is movably connected to the bottom surface of the vertical groove through a spring B.

[0010] Preferably, limiting grooves are arranged on the opposite sides of the outer surfaces of the two L-shaped plates, and the cross bar is adapted to the limiting grooves.

[0011] Preferably, a limiting plate is fixedly sleeved above the outer surface of the screw rod, and the lower end surface of the gasket is attached to the upper end surface of the limiting plate.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By providing an installation mechanism and a fixing mechanism, the present utility model facilitates the removal of the bolt head from the installation column. First, pull the cross bar downward to release the limitation on the L-shaped plate, and then move the two L-shaped plates towards both sides simultaneously. The spring A is compressed, and the movement of the L-shaped plate drives the movement of the clamping block. The clamping block moves out of the inner side of the clamping groove, releasing the limitation on the installation column, and the bolt head can be removed from the installation column. Place the gasket above the limiting plate, pull the cross bar downward, and then pull the two L-shaped plates outward. When the clamping block retracts into the inner side of the transverse groove, insert the installation column into the inner side of the installation groove, and then release the L-shaped plate. The clamping block snaps into the inner side of the clamping groove, and release the cross bar. Under the action of the spring B, the cross bar snaps into the inner side of the limiting groove to fix the L-shaped plate. This utility model is convenient for disassembling and assembling the bolt head and the installation column, thus facilitating the placement and replacement of the gasket, and it is not easy to fall off;

[0015] 2. By providing a correction mechanism, the present utility model first inserts the rotating plate into the slot hole of the screw rod that is needed, which can correct the rotation angle of the screw rod. When both sides of the rotating plate enter the slot hole, it indicates that the rotation angle of the screw rod is correct. At this time, rotate the screw rod so that the screw rod enters the hole at the correct angle. After entering the hole, the rotating plate rotates downward around the rotating shaft due to extrusion, which will not affect the rotation and contraction of the screw rod. This utility model prevents the screw rod from slipping due to rotation at the wrong angle. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 to 4 , an embodiment provided by the present utility model: a combined bolt fastener with anti-slip threads, including a screw rod 1. An installation column 9 is installed on the upper end surface of the screw rod 1. A bolt head 2 is arranged above the screw rod 1. An installation groove 8 is arranged on the lower end surface of the bolt head 2. The installation groove 8 is movably connected with the installation column 9 through an installation mechanism 3. The installation mechanism 3 includes an L-shaped plate 303. The L-shaped plate 303 is limited by a fixing mechanism 4. A gasket 5 is arranged above the outer surface of the screw rod 1. A vertical rod 6 is fixedly installed on the lower end surface of the screw rod 1. Correction mechanisms 7 are installed on both sides of the vertical rod 6. The correction mechanism 7 includes a rotating shaft 703. The rotating shaft 703 is arranged on both sides of the outer surface of the vertical rod 6 through a groove 702. A rotating plate 701 is sleeved on the outer surface of the rotating shaft 703.

[0023] Further, the L-shaped plate 303 is arranged before and after the upper end surface of the bolt head 2 through a transverse groove 301. The L-shaped plate 303 is movably connected with the inner wall of the transverse groove 301 through a spring A 302. Clamping blocks 304 are installed below the opposite sides of the outer surfaces of the two L-shaped plates 303. Clamping grooves 305 are arranged on both sides of the outer surface of the installation column 9; the transverse groove 301 is connected with the installation groove 8 through a through groove. The clamping block 304 penetrates through the through groove. The clamping block 304 is adapted to the clamping groove 305. The clamping block 304 can be clamped into the inner side of the clamping groove 305.

[0024] The fixing mechanism 4 includes a cross bar 401. The cross bar 401 is arranged on the front and rear end faces of the bolt head 2 through vertical slots 404. An outer jacket plate 402 is sleeved on the outer surface of the cross bar 401. The outer jacket plate 402 is movably connected to the bottom surface of the vertical slot 404 through a spring B 403. The cross bar 401 can move inside the vertical slot 404.

[0025] On the opposite sides of the outer surfaces of the two L-shaped plates 303, there are provided limit slots 405. The cross bar 401 is adapted to the limit slots 405, and the cross bar 401 can be inserted into the inside of the limit slots 405.

[0026] A limit plate 10 is fixedly sleeved above the outer surface of the screw rod 1. The lower end surface of the gasket 5 is attached to the upper end surface of the limit plate 10.

[0027] Both ends of the rotating shaft 703 are rotatably connected to the inner walls of the grooves 702 through bearings.

Under the action of the torsion springs, the rotating shaft 703 drives the rotating plate 701 to have a downward turning force, so that the lower end surface of the rotating plate 701 contacts the bottom surface of the groove 702.

[0028] When the combined bolt fastener with anti-slip threads is in use, by providing the installation mechanism 3 and the fixing mechanism 4, it is convenient to remove the bolt head 2 from the installation column 9. First, pull the cross bar 401 downward to release the limit on the L-shaped plate 303. Then, move the two L-shaped plates 303 to both sides at the same time. The spring A 302 is compressed. The movement of the L-shaped plate 303 drives the movement of the clamping block 304. The clamping block 304 leaves the inside of the clamping groove 305, releasing the limit on the installation column 9. The bolt head 2 can be removed from the installation column 9. Place the gasket 5 above the limit plate 10, pull the cross bar 401 downward, and then pull the two L-shaped plates 303 outward. When the clamping block 304 retracts into the inside of the horizontal slot 301, insert the installation column 9 into the inside of the installation groove 8, and then release the L-shaped plate 303.

Under the action of the spring B 403, the cross bar 401 is inserted into the inside of the limit slot 405 to fix the L-shaped plate 303. By providing the correction mechanism 7, the rotating plate 701 is first put into the slot hole where the screw rod 1 is needed, and the rotation angle of the screw rod 1 can be corrected. When the rotating plates 701 on both sides enter the slot holes, it means that the rotation angle of the screw rod 1 is correct. At this time, rotate the screw rod 1 so that the screw rod 1 enters the hole at the correct angle. After entering the hole, the rotating plate 701 rotates downward with the rotating shaft 703 as the center due to extrusion, and it will not affect the rotation and contraction of the screw rod 1. This utility model is convenient for disassembling and assembling the bolt head 2 and the installation column 9, so as to facilitate the placement and replacement of the gasket 5 and is not easy to fall off; and by providing the correction mechanism 7, the screw rod 1 will not cause thread slipping due to rotation at the wrong angle.
