Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of screws, and specifically relates to an anti-loosening screw assembly. Background Art
[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. Screws are the main fasteners for connecting and fixing various components of new energy vehicles. Using the physical principles of the inclined plane circular rotation of objects and friction, they are tools for gradually tightening objects, enabling two connecting parts to play a fastening role and being indispensable fasteners. However, after long-term use of existing screws, when a fixed position is affected by external forces for a long time, the screws are prone to unthreading, and then the fastening state of the screws becomes loose. Content of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide an anti-loosening screw assembly aiming at the above defects, which is not easy to loosen and makes the connection between the connecting part and the connected part firm and stable.
[0004] The technical solution adopted by the utility model to solve its technical problem is as follows: The anti-loosening screw assembly includes a connecting part, a connected part, a stud, and a screw head. The connected part is arranged below the connecting part. The screw head is arranged at the top end of the connecting part. The stud is arranged at the bottom end of the screw head. The stud passes through the connecting part and is threadedly connected with the connected part. On the upper surface of the connecting part, a horizontal guiding assembly is arranged on one side of the screw head. A driving assembly is drivably arranged on the horizontal guiding assembly. A C-shaped clamping part is arranged on the side of the driving assembly close to the screw head. The screw head is located inside the clamping hole of the clamping part. On the outer surface of the screw head, an upper limiting block is arranged at the top end of the clamping part. A lower limiting block is arranged at the bottom end of the clamping part.
[0005] Further, the horizontal guiding assembly includes guide rails symmetrically arranged on the upper surface of the connecting part, and sliding grooves opened on opposite end faces along the length direction of the guide rails. The driving assembly is located between the two guide rails.
[0006] Further, the driving assembly includes a driving part located between the two guide rails, sliders symmetrically arranged at both ends of the driving part, and a connecting block arranged at the top end of the driving part. The sliders are slidably connected with the sliding grooves. The connecting block is connected to the side of the clamping part far away from the opening.
[0007] Further, flaring parts are symmetrically arranged at both ends of the opening of the clamping part. The distance between the two flaring parts gradually increases from the opening to the side far away from the opening. The size of the opening of the clamping part is smaller than the outer diameter of the screw head.
[0008] The beneficial effects of the present utility model are as follows:
[0009] Through the cooperative setting among the horizontal guiding component, the driving component, the clamping member, the upper limit block and the lower limit block, after the screw fixes the connection between the connecting member and the connected member, the clamping member forms a clamping connection with the screw head along the horizontal guiding component through the driving component, so that the screw head is located inside the clamping hole of the clamping member. Since the clamping member is restricted by the driving component and can only move horizontally through the horizontal guiding component and cannot move up and down, and the clamping member is located between the upper limit block and the lower limit block, the clamping member then limits the axial movement of the screw, thereby preventing the screw from loosening and making the connection between the connecting member and the connected member firm and stable.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0015] The following further describes the present utility model in conjunction with the drawings.
[0016] Refer to Figures 1-3As shown in the figure, the anti-loosening screw assembly includes a connecting member 1, a connected member 2, a stud 3 and a screw head 4. The connected member 2 is arranged below the connecting member 1. The screw head 4 is arranged at the top end of the connecting member 3. The stud 3 is arranged at the bottom end of the screw head 4. The stud 3 passes through the connecting member 1 and is threadedly connected to the connected member 2. On the upper surface of the connecting member 1, a horizontal guiding assembly 5 is arranged on one side of the screw head 4. A driving assembly 6 is drivingly arranged on the horizontal guiding assembly 5. On one side of the driving assembly 6 close to the screw head 4, there is a C-shaped clamping member 7. The screw head 4 enters the inside of the clamping hole 701 through the opening of the C-shaped clamping member 7. The screw head 4 is located inside the clamping hole 701 of the clamping member 7. On the outer surface of the screw head 4, an upper limiting block 401 is arranged at the top end of the clamping member 7. A lower limiting block 402 is arranged at the bottom end of the clamping member 7. The outer diameters of the upper limiting block 401 and the lower limiting block 402 are larger than the inner diameter of the clamping hole 701. After the screw fixes the connection between the connecting member 1 and the connected member 2, the clamping member 7 forms a clamping connection with the screw head 4 along the horizontal guiding assembly 5 through the driving assembly 6, so that the screw head 4 is located inside the clamping hole 701 of the clamping member 7. Since the clamping member 7 is restricted by the driving assembly 6, it can only move horizontally through the horizontal guiding assembly 5 and cannot move up and down. And the clamping member 7 is located between the upper limiting block 7 and the lower limiting block 6. Then the clamping member 7 limits the axial movement of the screw, thereby preventing the screw from loosening and making the connection between the connecting member and the connected member firm and stable.
[0017] Preferably, the horizontal guiding assembly 5 includes guide rails 501 symmetrically arranged on the upper surface of the connecting member 1, and sliding grooves 502 opened on opposite end faces along the length direction of the guide rails 501. The driving assembly 6 is located between the two guide rails 501. The driving assembly 6 includes a driving member 601 located between the two guide rails 501, sliding blocks 602 symmetrically arranged at both ends of the driving member 601, and a connecting block 603 arranged at the top end of the driving member 601. The sliding blocks 602 are slidably connected to the sliding grooves 502. The connecting block 603 is connected to the side of the clamping member 7 away from the opening. The driving member 601 reciprocates along the sliding grooves 502 of the guide rails 501 through the sliding blocks 602, driving the connecting block 603 and the clamping member 7 to approach or move away from the screw head 4.
[0018] Preferably, flaring portions 702 are symmetrically arranged at both ends of the opening of the card member 7, and the distance between the two flaring portions 702 gradually increases from the opening side to the side away from the opening. The size of the opening of the card member 7 is smaller than the outer diameter of the screw head 4. The flaring portions 702 facilitate flaring the opening of the card member 7 to both sides, facilitating the entry of the screw head 4 into the card hole 701. When the card member 7 is clamped with the screw head 4, the flaring portions 702 first contact the outer surface of the screw head 4 and are extruded by the outer surface of the screw head 4. The flaring portions 702 move away from each other to expand the opening of the card member 7, causing elastic deformation, enabling the screw head 4 to enter the card hole 701. When the force squeezing the flaring portions 702 disappears, they rebound, and the sizes of the opening and the flaring portions are both smaller than the outer diameter of the screw head 4. Subsequently, the screw head 4 cannot move out from the opening and can stably cooperate with the upper limit block 401 and the lower limit block 402 to limit the axial movement of the screw.
[0019] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
