Description

Technical Field

[0001] This utility model relates to the field of U-shaped clamp technology, specifically a non-slip fastening U-shaped clamp. Background Technology

[0002] A clamp is a widely used mechanical fastener whose core function is to stably connect pipes, rods, equipment, etc. to structural components such as supports, walls, and steel columns through mechanical clamping force.

[0003] When using existing technology, when the bolts are tightened, the force is concentrated at both ends of the clamp, and the middle area may become suspended, which may cause the fixed object, such as a thin-walled pipe, to be deformed or even broken. The risk is even higher when fixing plastic pipes or precision equipment. Utility Model Content

[0004] The purpose of this utility model is to provide a non-slip fastening U-shaped clamp to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a non-slip fastening U-shaped clamp, comprising a clamp body, and further comprising: A fastening assembly is housed within the clamp body. The fastening assembly includes a connecting plate slidably connected to the clamp body, a turntable fixedly connected to the connecting plate, a sliding block slidably connected to the turntable, a second transmission rod fixedly connected to the turntable, a first sliding rod fixedly connected to the second transmission rod, a third transmission rod fixedly connected to the first sliding rod, a second transmission block slidably connected to the third transmission rod, a rubber plate fixedly connected to the second transmission block, a second sliding rod fixedly connected to the bottom of the turntable, a first transmission rod fixedly connected to the second sliding rod, and a first transmission block slidably connected to the first transmission rod. A clamping plate is fixedly connected to the clamping body, and a first bolt is threaded onto the clamping plate. A connecting piece is fixedly connected to the side of the clamping body away from the clamping plate, and a second bolt is threaded onto the connecting piece.

[0006] Furthermore, there are two clamping plates and two clamping bodies. The two clamping plates are respectively fixedly connected to the two clamping bodies on the side away from the turntable, and the two clamping plates are threaded in opposite directions on the first bolt.

[0007] Using the above technical solution: when in use, by tightening the first bolt, the two clamp bodies can be clamped inward or moved away from each other.

[0008] Furthermore, the two clamp bodies are respectively fixedly connected to the bottom of the connector near the two ends of the clamp body on the side away from the clamping plate.

[0009] The above technical solution is adopted: by setting two clamp bodies and connecting them with the connector, the connector can act as an iron spring to connect the two clamp bodies.

[0010] Furthermore, both the first transmission block and the second transmission block are provided with oblique holes.

[0011] The above technical solution is adopted: by opening an oblique hole, when the sliding block is pressed down, it can drive the first transmission block to move; when the first sliding rod is pulled to move, it can drive the second transmission block to move.

[0012] Furthermore, the rubber plate is slidably connected to the inner wall of the clamp body.

[0013] Using the above technical solution: when the second transmission block slides inside the clamp body, it can be driven by the second transmission rod to move, causing the rubber plate to be driven to move inward and clamp, thereby realizing the rubber plate sliding to the inner wall of the clamp body.

[0014] Furthermore, a limiting rod is fixedly connected to the bottom of the sliding block, and a sliding groove is provided on the turntable, with the limiting rod slidably connected in the sliding groove on the turntable.

[0015] The above technical solution is adopted: by setting a limit rod, it is convenient to limit the position of the sliding block during use.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, when the first bolt is tightened, the clamping plates on both sides drive the clamp body to move inward. The rubber plate is squeezed by the force, causing the second transmission block to slide. Through the sliding transmission of the third transmission rod in the inclined hole of the second transmission block, the second transmission rod, the turntable and the second sliding rod are driven to move downward. This causes the first transmission rod to push the first transmission block out laterally, ultimately achieving synchronous and uniform clamping of the pipe at both ends and in the middle area of ​​the clamp. This avoids the problem of force concentration at both ends and the gap in the middle when tightening traditional bolts, significantly improving clamping reliability and pipe protection effect.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: like Figures 1-5 As shown, this utility model provides a technical solution: a non-slip fastening U-shaped clamp, including a clamp body 1, and further including: Fastening assembly 2 is placed inside clamp body 1. Fastening assembly 2 includes a connecting plate 211 slidably connected to clamp body 1, a turntable 21 fixedly connected to the connecting plate 211, a sliding block 22 slidably connected to the turntable 21, a second transmission rod 25 fixedly connected to the turntable 21, a first sliding rod 27 fixedly connected to the second transmission rod 25, a third transmission rod 29 fixedly connected to the first sliding rod 27, a second transmission block 26 slidably connected to the third transmission rod 29, a rubber plate 210 fixedly connected to the second transmission block 26, a second sliding rod 212 fixedly connected to the bottom of the turntable 21, a first transmission rod 24 fixedly connected to the second sliding rod 212, and a first transmission block 23 slidably connected to the first transmission rod 24. A clamping plate 3 is fixedly connected to the clamping body 1. A first bolt 31 is threadedly connected to the clamping plate 3. A connector 32 is fixedly connected to the side of the clamping body 1 away from the clamping plate 3. A second bolt 33 is threadedly connected to the connector 32.

[0025] In this invention, when the first bolt 31 is tightened, the clamping plates 3 on both sides drive the clamp body 1 to move inward. The rubber plate 210 is squeezed by the force, causing the second transmission block 26 to slide. Through the sliding transmission of the third transmission rod 29 in the inclined hole of the second transmission block 26, the second transmission rod 25, the turntable 21 and the second sliding rod 212 are driven to move downward, thereby causing the first transmission rod 24 to push the first transmission block 23 out laterally. Finally, the clamping of the pipe is achieved synchronously and evenly at both ends and in the middle area, avoiding the problem of force concentration at both ends and emptiness in the middle when tightening traditional bolts, and significantly improving the clamping reliability and pipe protection effect.

[0026] Furthermore, such as Figures 1 to 5 As shown, there are two clamping plates 3 and two clamping bodies 1. The two clamping plates 3 are fixedly connected to the two clamping bodies 1 on the side away from the turntable 21. The two clamping plates 3 are threaded in opposite directions on the first bolt 31. By setting clamping plates 3 with opposite threaded directions on the two clamping bodies 1, when using the first bolt 31, the reverse characteristics of the threaded transmission can be used to synchronously drive the two clamping bodies 1 to clamp inward or separate outward, thereby achieving the clamping or release of the pipeline. The operation is convenient and the clamping force is symmetrical and uniform.

[0027] The two clamp bodies 1 are fixedly connected to the two ends of the bottom of the connector 32 near the clamp body 1 on the side away from the clamping plate 3. The connector 32 adopts an iron spring sheet structure, which connects the two clamp bodies 1 to form an elastic linkage whole. It can not only provide support and positioning for the clamp body 1, but also adapt to the small angular deviation during pipeline installation through its own elastic deformation, thereby enhancing structural compatibility and vibration resistance.

[0028] Both the first transmission block 23 and the second transmission block 26 are provided with oblique holes. The oblique holes form a wedge-shaped transmission structure. When the sliding block 22 is pressed down, the first transmission block 23 is driven to move laterally through the guiding effect of the oblique holes, thereby achieving the clamping of the pipe sidewall. When the first sliding rod 27 is pulled and moved, the second transmission block 26 is driven to slide longitudinally through the oblique holes, thereby driving the rubber plate 210 to clamp towards the pipe. The synergistic effect of multi-directional clamping force is achieved through mechanical transmission.

[0029] like Figure 3 as well as Figure 4 As shown, the rubber plate 210 is slidably connected to the inner wall of the clamp body 1. When the second transmission block 26 slides inside the clamp body 1 under the drive of the second transmission rod 25, the rubber plate 210 moves inward synchronously with it, using the elastic deformation of the rubber material to tightly fit the pipe surface, fill the gap and provide anti-slip friction, while avoiding direct metal compression that could damage the pipe.

[0030] like Figure 3As shown, a limiting rod 28 is fixedly connected to the bottom of the sliding block 22, and a sliding groove is provided on the turntable 21. The limiting rod 28 is slidably connected in the sliding groove on the turntable 21. The cooperation between the limiting rod 28 and the sliding groove forms a sliding guide structure. During the movement of the sliding block 22, the limiting rod 28 slides along the sliding groove, which can limit the movement trajectory of the sliding block 22, prevent it from deviating or rotating, ensure that the driving effect of the sliding block 22 on the turntable 21 is stable and reliable, and improve the accuracy and safety of the clamping process.

[0031] Working principle: such as Figures 1 to 5 As shown, when in use, first put the clamp body 1 on the pipe. When it is necessary to clamp the pipe, just turn the first bolt 31 to make the clamping plates 3 on both sides move inward to clamp the pipe. During this process, the rubber plate 210 is forced to move closer to the clamp body 1, causing the second transmission block 26 to slide towards the side closer to the clamp body 1, causing the third transmission rod 29 to slide on the inclined hole on the first sliding rod 27, the third transmission rod 29 drives the first sliding rod 27 to slide down, causing the second transmission rod 25 to slide down, causing the turntable 21 to slide down, causing the second sliding rod 212 to drive the first transmission rod 24 to slide down the first transmission block 23, pushing the first transmission block 23 out and clamping the pipe; Then, slide block 22 is removed from turntable 21 and fixed to connector 32 with bolts to limit the sliding block 22 and achieve complete clamping of the pipe.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
