Abstract
Description
Technical Field
[0001] This utility model relates to a universal clip, and more particularly to a universal clip, belonging to the field of photography and videography technology. Background Technology
[0002] A universal clamp is a multi-functional clamping tool, usually made of metal or high-strength plastic, with adjustable jaws and flexible arms. It can adapt to objects of different shapes and sizes and is widely used in photography, videography, stage lighting, laboratories and other scenarios.
[0003] Most universal clamps on the market use springs to connect the upper and lower clamping blocks. When stable clamping is required, the spring must have sufficient elasticity. However, when the spring elasticity is large, the operator must apply a lot of force to open the universal clamp and connect it to the placement surface, which undoubtedly increases the difficulty for workers to use the universal clamp.
[0004] Therefore, there is an urgent need to improve a universal clip to solve the aforementioned problems. Utility Model Content
[0005] The purpose of this utility model is to provide a universal clip that not only makes it convenient for staff to use, but also ensures that the universal clip is firmly held in place on the surface.
[0006] To achieve the above objectives, the main technical solution adopted by this utility model includes: a universal clamp, comprising a first clamping block, a second clamping block rotatably connected to the first clamping block via a rotating rod, auxiliary blocks rotatably connected to both the first clamping block and the second clamping block, threaded rods penetrating through the two auxiliary blocks from top to bottom, and the threaded rods being threadedly connected to the two auxiliary blocks, and arc-shaped slots for accommodating the positional displacement of the threaded rods being provided on both the first clamping block and the second clamping block, and a threaded clamping block rotatably connected to one side of the second clamping block.
[0007] Preferably, an anti-slip plate is fixedly installed on the side of the first clamping block near the second clamping block, and the threaded rod also passes through the first clamping block and the second clamping block.
[0008] Preferably, a reinforcing block is fixedly installed on one side of the second clamping block, the reinforcing block and the threaded clamping block are located on the same plane, and the threaded clamping block is rotatably connected to the reinforcing block through a rotating rod.
[0009] Preferably, a housing is fixedly installed inside the rotating rod. A first slot and a second slot are provided on one side of the housing. A fixing block is provided above the second slot and is fixedly installed with the housing. A sliding groove is provided inside the fixing block. A sliding rod is slidably connected to the sliding groove. A first spring is fixedly installed between the protruding part of the sliding rod and the sliding groove. The sliding rod extends to the outside of the rotating rod.
[0010] Preferably, a push rod is slidably installed inside the housing, one end of the push rod extends to the outside of the rotating rod, an elastic connecting rod is fixedly installed on one side of the push rod, a protrusion is fixedly installed on one end of the elastic connecting rod, and a second spring is fixedly installed between the end of the elastic connecting rod away from the protrusion and the inner wall of the housing.
[0011] Preferably, the push rod extends to the outside of the housing, and a connecting block is fixedly installed at the other end of the push rod. A first connecting rod is fixedly installed on both sides of the connecting block. A second connecting rod is fixedly connected to the first connecting rod through a third spring. The second connecting rod is slidably disposed inside the first connecting rod. A limit block is fixedly installed at the end of the second connecting rod away from the third spring.
[0012] Preferably, the rotating rod has arc-shaped sliding grooves on both sides, and the arc-shaped sliding grooves are slidably connected to the limiting block. The reinforcing block has a circular groove on one side, and the circular groove is rotatably connected to the rotating rod. Limiting grooves are opened on both sides of the circular groove, and the limiting grooves are slidably connected to the limiting block. The circular groove is connected to the limiting groove.
[0013] This utility model has at least the following beneficial effects:
[0014] 1. The worker places the placement surface between the first clamping block and the second clamping block, and rotates the threaded rod to make the first clamping block and the second clamping block open and close at the end away from the rotating rod, so as to firmly clamp the placement surface. At the same time, the threaded rod is threadedly connected to the auxiliary block, so that the first clamping block and the second clamping block can be firmly supported to the placement surface.
[0015] 2. When it is necessary to limit the rotation angle of the threaded clamp, the operator pushes the push rod inward towards the rotating rod. The protrusion slides inside the housing. When the protrusion slides to the second slot, due to the plastic material of the elastic connecting rod, it will cause the protrusion to be locked into the second slot. At the same time, the limiting block slides inside the rotating rod and slides along the arc-shaped sliding groove to the outside of the rotating rod, so that the limiting block is locked in the limiting groove, thereby limiting the rotation angle of the threaded clamp.

[0024] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0025] Examples, such as Figures 1-6As shown, a universal clamp includes a first clamping block 1, a second clamping block 2 rotatably connected to the first clamping block 1 via a rotating rod 3, and auxiliary blocks 5 rotatably connected to both the first clamping block 1 and the second clamping block 2. A threaded rod 4 passes through both auxiliary blocks 5 from top to bottom, and the threaded rod 4 is threadedly connected to the two auxiliary blocks 5. Both the first clamping block 1 and the second clamping block 2 have arc-shaped slots 7 for accommodating the displacement of the threaded rod 4. A threaded clamping block 9 is rotatably connected to one side of the second clamping block 2. When a worker places a surface between the first clamping block 1 and the second clamping block 2, rotating the threaded rod 4 causes the first clamping block 1 and the second clamping block 2 to open and close at the end away from the rotating rod 3, securing them firmly to the surface. The rotation of the first clamping block 1 and the second clamping block 2 causes the arc-shaped slots 7 to move, ensuring that the threaded rod 4 remains vertical for easy reuse. Simultaneously, the threaded rod 4 is threadedly connected to the auxiliary blocks 5, thus ensuring a secure grip between the first clamping block 1 and the second clamping block 2 and the surface.
[0026] like Figures 1-5 As shown, further, an anti-slip plate 8 is fixedly installed on the side of the first clamping block 1 near the second clamping block 2. The threaded rod 4 also passes through the first clamping block 1 and the second clamping block 2. A reinforcing block 10 is fixedly installed on one side of the second clamping block 2. The reinforcing block 10 and the threaded clamping block 9 are located on the same plane. The threaded clamping block 9 is rotatably connected to the reinforcing block 10 through the rotating rod 13. By fixing the anti-slip plate 8 on one side of the first clamping block 1, the first clamping block 1 and the second clamping block 2 can be more stable when clamped with the placement surface. By setting the threaded clamping block 9 to be rotatably connected to the rotating rod 13, when the worker needs to use the threaded clamping block 9 in multiple directions, it can be rotated to the required angle.
[0027] like Figure 1 , Figure 5 as well as Figure 6As shown, further, a housing 16 is fixedly installed inside the rotating rod 13. A first slot 17 and a second slot 18 are provided on one side of the housing 16. A fixing block 28 is provided above the second slot 18 and is fixedly installed with the housing 16. A sliding groove 29 is provided inside the fixing block 28. A sliding rod 27 is slidably connected to the sliding groove 29. A first spring 30 is fixedly installed between the protruding part of the sliding rod 27 and the sliding groove 29. The sliding rod 27 extends to the outside of the rotating rod 13. A pressing rod 15 is slidably installed inside the housing 16. One end of the pressing rod 15 extends to the outside of the rotating rod 13. An elastic connecting rod 19 is fixedly installed on one side of the pressing rod 15. A protrusion 20 is fixedly installed on one end of the elastic connecting rod 19. A second spring 21 is fixedly installed between the end of the elastic connecting rod 19 away from the protrusion 20 and the inner wall of the housing 16. The housing 16 is slidably positioned outside the pressing rod 15 and is fixedly installed inside the rotating rod 13. A first slot 17 and a second slot 18 are provided on one side of the housing 16. The protrusion 20 is inclined. When the operator pushes the pressing rod 15 inward toward the rotating rod 13, the protrusion 20 slides out of the first slot. The slot 17 fits against the inner wall of the housing 16. When the operator continues to push the push rod 15, when the protrusion 20 slides to the second slot 18, due to the plastic material of the elastic connecting rod 19, the protrusion 20 will be driven into the second slot 18. At this time, the second spring 21 is in a compressed state. If it is necessary to slide the protrusion 20 out of the second slot 18, the operator needs to press the sliding rod 27. The sliding rod 27 moves into the housing 16, thereby pressing the protrusion 20. And because the elastic connecting rod 19 moves away from the protrusion 20... A second spring 21 is fixedly installed between the end and the inner wall of the housing 16. The spring force of the second spring 21 drives the pressing rod 15 to move outward of the rotating rod 13. At this time, the protrusion 20 slides against the inner wall of the housing 16, so that the protrusion 20 can be inserted into the first hole groove 17. At the same time, when the operator presses the sliding rod 27, a first spring 30 is fixedly installed between the protruding part of the sliding rod 27 and the sliding groove 29. The spring force of the first spring 30 drives the sliding rod 27 to move upward, so that the operator can press the sliding rod 27 again.
[0028] like Figures 5-6As shown, further, the push rod 15 extends to the outside of the housing 16. A connecting block 22 is fixedly installed at the other end of the push rod 15. A first connecting rod 23 is fixedly installed on both sides of the connecting block 22. The first connecting rod 23 is fixedly connected to a second connecting rod 25 through a third spring 24. The second connecting rod 25 is slidably disposed inside the first connecting rod 23. A limit block 26 is fixedly installed at the end of the second connecting rod 25 away from the third spring 24. An arc-shaped sliding groove 14 is opened on both sides of the rotating rod 13. The arc-shaped sliding groove 14 is slidably connected to the limit block 26. A circular groove 11 is opened on one side of the reinforcing block 10. The circular groove 11 is rotatably connected to the rotating rod 13. A limit groove 12 is opened on both sides of the circular groove 11. The limit groove 12 is slidably connected to the limit block 26. The circular groove 11 and the limit groove 12 are connected. When the rotating rod 13 is slidably connected to the circular groove 11, the threaded clamp 9 can be rotated, and the limit block 26 is simultaneously rotated. 26 is in contact with the inner wall of the rotating rod 13. At this time, the third spring 24 is in a compressed state. When the operator pushes the push rod 15 to drive the protrusion 20 to be stuck in the second hole groove 18, the limiting block 26 slides inside the rotating rod 13 and slides along the arc-shaped sliding groove 14 to the outside of the rotating rod 13. At this time, the third spring 24 is in a stretched state, so that the limiting block 26 is stuck in the limiting groove 12, thereby limiting the rotation angle of the threaded clamp 9. When it is necessary to rotate the threaded clamp 9 again, the operator presses the sliding rod 27, which cooperates with the elastic force of the second spring 21 to make the protrusion 20 slide and be stuck in the first hole groove 17, thereby driving the push rod 15 and the connecting block 22 to move. Thus, the connecting block 22 drives the limiting block 26 to slide into the rotating rod 13. At this time, the third spring 24 is in a compressed state, and then the threaded clamp 9 can continue to be rotated to change its angle.
[0029] In this embodiment, as Figures 1-6 As shown, the principle of the universal clip provided in this embodiment is as follows:
[0030] The operator places the placement surface between the first clamping block 1 and the second clamping block 2, and rotates the threaded rod 4 to open and close the first clamping block 1 and the second clamping block 2 away from the rotating rod 3, thus firmly clamping them to the placement surface. At the same time, the threaded rod 4 is threadedly connected to the auxiliary block 5, thereby ensuring that the first clamping block 1 and the second clamping block 2 are firmly secured to the placement surface. The operator can also rotate the threaded clamping block 9 for use. When it is necessary to limit the rotation angle of the threaded clamping block 9, the operator pushes the pressing rod 15 inward towards the rotating rod 13, and the protrusion 20 slides within the housing 16. When the protrusion 20 slides to the second hole groove 18, due to the plastic material of the elastic connecting rod 19, it will cause the protrusion 20 to engage in the second hole. Inside the groove 18, the limiting block 26 slides inside the rotating rod 13 and slides along the arc-shaped sliding groove 14 to the outside of the rotating rod 13. At this time, the third spring 24 is in a stretched state, so that the limiting block 26 is stuck in the limiting groove 12, thereby limiting the rotation angle of the threaded clamp 9. When the threaded clamp 9 needs to be rotated again, the operator presses the sliding rod 27, which cooperates with the elastic force of the second spring 21 to make the protrusion 20 slide and get into the first hole groove 17, thereby driving the pressing rod 15 and the connecting block 22 to move. Thus, the connecting block 22 drives the limiting block 26 to slide inside the rotating rod 13. At this time, the third spring 24 is in a compressed state, and then the threaded clamp 9 can continue to be rotated to change its angle.
