Description

Technical Field

[0001] The invention relates to the technical field of auxiliary tools, in particular to a foldable thread locking clamp. Background Art

[0002] Most of the existing locking clamps with similar functions on the market are directly formed ear plates (i.e., the support plate and pressure plate described in this article), which cannot be folded. Tension springs are mostly used to close the two ear plates. If the tension is large, it is easy to damage the equipment, or if the tension is small, the clamping is unstable and easy to slip, and it is impossible to automatically clamp and fix the two ends of the equipment. Therefore, this foldable threaded locking clamp is designed to meet the above situation and the needs of a certain project. Summary of the invention

[0003] The object of the present invention is to provide a foldable thread locking clip to solve the above-mentioned problems.

[0004] To achieve the above object, the present invention provides the following technical solution: a foldable threaded locking clamp, comprising a spring seat and a threaded pin, the top of the spring seat is hinged with a pressure plate through the threaded pin, the bottom of the spring seat is hinged with a support block through the threaded pin, and a wire thread sleeve is rotatably arranged at the middle end of the spring seat;

[0005] A threaded rod is rotatably arranged at the middle end inside the screw seat, and the threaded rod is cooperatively connected with the wire screw sleeve. A star-shaped handle is arranged on the top of the screw seat, and the bottom of the star-shaped handle is fixedly connected to the top of the threaded rod. Side fixing structures are arranged on both sides of the spring seat.

[0006] Preferably, sliding rods for limiting are fixedly provided at both ends of the bottom of the screw seat, a top rod is fixedly provided at the bottom end inside the spring seat, a compression spring for resetting the sliding rod is provided on the top of the top rod, and the top of the compression spring is fixedly connected to the bottom of the sliding rod.

[0007] Preferably, the side fixing structure protects the connecting rotating columns rotatably arranged at both ends of the spring seat, a rotating plate connected to the connecting rotating columns, a shock-absorbing protection fixing box arranged at one end of the rotating plate, a shock-absorbing telescopic column arranged inside the shock-absorbing protection fixing box, a side clamping fixing clamp fixedly connected to the shock-absorbing telescopic column, and a linkage rotating cylinder rotatably arranged at both ends inside the spring seat, and a rotating thread is opened at the bottom of the sliding rod.

[0008] Preferably, a thread that cooperates with the rotating thread is opened inside the linkage rotating cylinder, and placement grooves are opened at both ends of the spring seat surface. A transfer linkage gear is arranged inside the placement groove, and the left end of the transfer linkage gear is meshed with the gear teeth on the surface of the connecting rotating column, and the right end of the transfer linkage gear is meshed with the gear teeth on the surface of the linkage rotating cylinder.

[0009] Preferably, a fixed shock-absorbing spring is fixedly arranged inside the shock-absorbing protection fixed box, a free end of the fixed shock-absorbing spring is fixedly connected to a connecting support plate, and a surface of the connecting support plate is fixedly connected to the shock-absorbing telescopic column.

[0010] Preferably, a first protective pad for shock absorption is provided on the bottom of the pressing plate and the top of the supporting block.

[0011] Preferably, both ends of the bottom of the pressing plate and both ends of the top of the supporting block are provided with anti-slip bosses.

[0012] Preferably, a second protective pad for absorbing shock of the equipment is provided inside the side clamping fixing clamp.

[0013] Preferably, the surface of the spring seat is provided with connection and fixing screw holes for connecting the device with other equipment.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The star-shaped handle can be used to drive the threaded rod inside the screw seat to rotate. When the threaded rod rotates inside the wire screw sleeve, the threaded rod will move up and down. When the threaded rod moves, it will simultaneously drive the screw seat and the pressure plate to move downward. The pressure plate can be moved to the top of the equipment and cooperate with the support block to squeeze the equipment, thereby achieving the effect of clamping and fixing the equipment. The star-shaped handle can be used to adjust the clamping force of the equipment to prevent the equipment from being damaged. It can also prevent the equipment from falling off due to insufficient clamping force, which is convenient for users to use and can be used to cushion the shock of the equipment through the compression spring.

[0016] When the device is clamped, the sliding rod can be moved downward to drive the linkage rotating cylinder inside the spring seat to rotate, and the rotating thread and the thread inside the linkage rotating cylinder make it convenient to rotate the linkage rotating cylinder, which is convenient for driving the subsequent device to rotate. When the linkage rotating cylinder rotates, the gear teeth on its surface will drive the transfer linkage gear to rotate, and the transfer linkage gear can drive the connecting rotating column to rotate through the gear teeth on the surface of the connecting rotating column. When the connecting rotating column rotates, it will drive the rotating plate to rotate, so that the rotating plate can be rotated from the back side of the spring seat to the front side. After the rotating plate is rotated to the front side, the side clamping and fixing pliers will contact and squeeze the two sides of the device on both sides of the device, thereby fixing the device to prevent the device from detaching from the two sides. At the same time, it is also convenient for users to place the device at different angles. When the sliding rod moves upward, it will drive the linkage rotating cylinder to reverse, and finally drive the rotating plate to rotate toward the back side of the spring seat, thereby realizing the effect of automatic clamping and retraction.

[0017] When clamping the side of the device, the fixed shock-absorbing spring inside the shock-absorbing protection fixing box can drive the connecting support plate and the shock-absorbing telescopic column to be extended and retracted, thereby driving the subsequent side clamping fixing clamp to be extended and retracted, which is convenient for protecting and shock-absorbing both sides of the device to prevent excessive force from causing damage to the equipment, and is also convenient for fixing and clamping devices of different sizes.

[0018] The first protection pad at the bottom of the pressure plate and the top of the support block can provide shock-absorbing protection for the upper and lower ends of the equipment, thereby preventing excessive force from causing damage to the equipment and facilitating the protection of the equipment. The second protection pad inside the side clamping clamp can provide shock-absorbing protection for both sides of the equipment, further reducing the possibility of equipment damage.

[0028] See also Figures 1 to 6 The present invention provides a technical solution: a foldable threaded locking clamp, comprising a spring seat 2 and a threaded pin 7. Specifically, a pressure plate 5 is hingedly connected to the top of the spring seat 2 through the threaded pin 7, a support block 1 is hingedly connected to the bottom of the spring seat 2 through the threaded pin 7, and a wire thread sleeve 9 is rotatably arranged at the middle end of the spring seat 2;

[0029] A threaded rod 8 is rotatably arranged at the middle end inside the screw seat 4, and the threaded rod 8 is matched and connected with the wire screw sleeve 9. A star-shaped handle 6 is arranged on the top of the screw seat 4, and the bottom of the star-shaped handle 6 is fixedly connected with the top of the threaded rod 8. Side fixing structures are arranged on both sides of the spring seat 2. When in use, the device to be clamped and fixed can be placed on the surface of the spring seat 2, and the bottom of the device can be placed on the surface of the support block 1. The device can be supported by the support block 1. After the device is placed, the star-shaped handle 6 on the top of the screw seat 4 can be rotated, and the screw can be driven by the star handle 6. The threaded rod 8 inside the nail seat 4 rotates. When the threaded rod 8 rotates inside the wire screw sleeve 9, the threaded rod 8 will move up and down. When the threaded rod 8 moves, it will simultaneously drive the screw seat 4 and the pressure plate 5 to move downward. The pressure plate 5 can be moved to the top of the device and cooperate with the support block 1 to squeeze the device, thereby achieving the effect of clamping and fixing the device. The star-shaped handle 6 can adjust the clamping force of the device to prevent the device from being damaged. At the same time, it can also avoid the situation where the clamping force is insufficient and the device falls off, which is convenient for users to use.

[0030] Specifically, sliding rods 3 for limiting are fixedly provided at both ends of the bottom of the screw seat 4, a push rod 11 is fixedly provided at the bottom end inside the spring seat 2, and a compression spring 10 for resetting the sliding rod 3 is provided on the top of the push rod 11, and the top of the compression spring 10 is fixedly connected to the bottom of the sliding rod 3; after use, the star handle 6 can be rotated in the reverse direction to drive the threaded rod 8 to reverse, thereby driving the screw seat 4 to move downward and disconnect from the equipment to facilitate the removal of the equipment. At the same time, the compression spring 10 can facilitate the upward movement of the screw seat 4, and can also play a buffering effect when the equipment is squeezed and fixed. The sliding rod 3 can be used to limit the screw seat 4 to prevent the screw seat 4 from rotating.

[0031] Specifically, the side fixing structure protects the rotation of the connecting rotating columns 16 arranged at both ends of the spring seat 2, the rotating plate 12 connected to the connecting rotating columns 16, the shock-absorbing protection fixing box 19 arranged at one end of the rotating plate 12, the shock-absorbing telescopic column 20 arranged inside the shock-absorbing protection fixing box 19, the side clamping fixing clamp 21 fixedly connected to the shock-absorbing telescopic column 20, and the linkage rotating cylinder 24 rotatably arranged at both ends inside the spring seat 2, and the bottom of the sliding rod 3 is provided with a rotating thread 23; when the equipment is clamped, the linkage rotating cylinder 24 inside the spring seat 2 can be driven to rotate by moving the sliding rod 3 downward, and the rotating thread 23 and the thread inside the linkage rotating cylinder 24 facilitate the rotation of the linkage rotating cylinder 24, so as to drive the subsequent device to rotate.

[0032] Specifically, a thread that cooperates with the rotating thread 23 is provided inside the linkage rotating cylinder 24, and placement grooves 17 are provided at both ends of the surface of the spring seat 2. A transfer linkage gear 18 is provided inside the placement groove 17 for rotation. The left end of the transfer linkage gear 18 is meshed and connected with the gear teeth on the surface of the connecting rotating column 16, and the right end of the transfer linkage gear 18 is meshed and connected with the gear teeth on the surface of the linkage rotating cylinder 24. When the linkage rotating cylinder 24 rotates, the transfer linkage gear 18 is driven to rotate by the gear teeth on its surface, and the transfer linkage gear 18 can drive the connecting rotating column 16 to rotate by the gear teeth on the surface of the connecting rotating column 16. When rotating, the rotating plate 12 will be driven to rotate, so that the rotating plate 12 can be rotated from the back side of the spring seat 2 to the front side. After the rotating plate 12 is rotated to the front side, the side clamping and fixing clamps 21 will contact and squeeze the two sides of the device on both sides of the device, thereby fixing the device to prevent the device from detaching from the two sides, and at the same time, it is convenient for users to place the device at different angles. When the sliding rod 3 moves upward, it will drive the linked rotating cylinder 24 to reverse, and finally drive the rotating plate 12 to rotate toward the back side of the spring seat 2, thereby achieving the effect of automatic clamping and retraction, reducing the steps of manual operation, and facilitating user use.

[0033] Specifically, a fixed shock-absorbing spring 25 is fixedly arranged inside the shock-absorbing protection fixed box 19, and the free end of the fixed shock-absorbing spring 25 is fixedly connected to a connecting support plate 26, and the surface of the connecting support plate 26 is fixedly connected to the shock-absorbing telescopic column 20; when clamping the side of the equipment, the fixed shock-absorbing spring 25 inside the shock-absorbing protection fixed box 19 can drive the connecting support plate 26 and the shock-absorbing telescopic column 20 to be extended and retracted, thereby driving the subsequent side clamping fixing clamp 21 to be extended and retracted, which is convenient for protecting and shock-absorbing both sides of the equipment, preventing excessive force from causing damage to the equipment, and also convenient for fixing and clamping equipment of different sizes.

[0034] Specifically, the bottom of the pressure plate 5 and the top of the support block 1 are both provided with a first protective pad 14 for shock absorption. When the device is clamped, the first protective pad 14 at the bottom of the pressure plate 5 and the top of the support block can provide shock absorption protection for the upper and lower ends of the device, thereby preventing excessive force from causing damage to the device and facilitating the protection of the device.

[0035] Specifically, both ends of the bottom of the pressure plate 5 and both ends of the top of the support block 1 are provided with anti-drop bosses 15; when the device is clamped, the anti-drop bosses 15 are used to limit the device and prevent it from falling off.

[0036] Specifically, a second protection pad 22 for cushioning the device is provided inside the side clamping fixing clamp 21; the second protection pad 22 inside the side clamping fixing clamp 21 can provide cushioning protection for both sides of the device, thereby further reducing the possibility of damage to the device.

[0037] Specifically, the surface of the spring seat 2 is provided with a connecting and fixing screw hole 13 for connecting the device to other equipment; the connecting and fixing screw hole 13 facilitates the installation of the device on a wall or other equipment by screws engaging with the connecting and fixing screw hole 13.

[0038] Working process: When in use, the device to be clamped and fixed can be placed on the surface of the spring seat 2, and the bottom of the device can be placed on the surface of the support block 1. The device can be supported by the support block 1. After the device is placed, the star-shaped handle 6 on the top of the screw seat 4 can be rotated, and the threaded rod 8 inside the screw seat 4 can be driven to rotate by the star-shaped handle 6;

[0039] When the threaded rod 8 rotates inside the wire screw sleeve 9, the threaded rod 8 will move up and down. When the threaded rod 8 moves, it will drive the screw seat 4 and the pressure plate 5 to move downward at the same time, and the pressure plate 5 can be moved to the top of the device to cooperate with the support block 1 to squeeze the device, so as to achieve the effect of clamping and fixing the device. The clamping force of the device can be adjusted by the star-shaped handle 6, so as to prevent the device from being damaged by clamping, and also avoid the situation that the clamping force is insufficient and the device falls off, which is convenient for users to use;

[0040] After use, the star-shaped handle 6 can be rotated in the opposite direction to drive the threaded rod 8 to reverse, thereby driving the screw seat 4 to move downward and disconnect from the device, so as to facilitate the removal of the device. At the same time, the compression spring 10 can facilitate the upward movement of the screw seat 4, and can also play a buffering effect when the device is squeezed and fixed. The sliding rod 3 can be used to limit the screw seat 4 to prevent the screw seat 4 from rotating;

[0041] When clamping the device, the sliding rod 3 moves downward to drive the linkage rotating cylinder 24 inside the spring seat 2 to rotate, and the rotating thread 23 and the thread inside the linkage rotating cylinder 24 facilitate the linkage rotating cylinder 24 to rotate, which is convenient for driving the subsequent device to rotate;

[0042] When the linkage rotating cylinder 24 rotates, the gear teeth on its surface will drive the intermediate linkage gear 18 to rotate. The intermediate linkage gear 18 can drive the connecting rotating column 16 to rotate through the gear teeth on the surface of the connecting rotating column 16. When the connecting rotating column 16 rotates, the rotating plate 12 will be driven to rotate, so that the rotating plate 12 can be rotated from the back side of the spring seat 2 to the front side. After the rotating plate 12 rotates to the front side, the side clamping and fixing clamps 21 will contact and squeeze the two sides of the device on both sides of the device, thereby fixing the device to prevent the device from detaching from both sides.

[0043] At the same time, it is convenient for users to place the device at different angles. When the sliding rod 3 moves upward, it will drive the linkage rotating cylinder 24 to reverse, and finally drive the rotating plate 12 to rotate toward the back of the spring seat 2, thereby achieving the effect of automatic clamping and retracting, reducing the steps of manual operation, and facilitating the use of users;

[0044] When clamping the side of the device, the fixed shock-absorbing spring 25 inside the shock-absorbing protection fixing box 19 can drive the connecting support plate 26 and the shock-absorbing telescopic column 20 to be extended and retracted, thereby driving the subsequent side clamping fixing clamp 21 to be extended and retracted, which is convenient for protecting and shock-absorbing both sides of the device, preventing excessive force from causing damage to the device, and also convenient for fixing and clamping devices of different sizes;

[0045] When clamping the device, the first protection pad 14 at the bottom of the pressure plate 5 and the top of the support block can provide shock-absorbing protection for the upper and lower ends of the device, thereby preventing excessive force from causing damage to the device and facilitating the protection of the device. The anti-slip boss 15 can be used to limit the device to prevent it from falling off. The second protection pad 22 inside the side clamping clamp 21 can provide shock-absorbing protection for both sides of the device, further reducing the possibility of damage to the device. The connecting and fixing screw holes 13 can be used to facilitate the installation of the device on a wall or other equipment, and the screws can be used to cooperate with the connecting and fixing screw holes 13.
