Description

Technical Field

[0001] This utility model relates to the field of pipe cutting and positioning technology, specifically to a pipe fixing device. Background Technology

[0002] In many fields such as pipeline engineering, machinery manufacturing, building installation, petrochemicals, and municipal construction, pipe cutting (including metal pipes, PVC pipes, and composite pipes) is an extremely common and critical process. Accurate, efficient, and safe pipe cutting directly affects the quality of subsequent welding, connection, and installation, and also influences the overall project schedule and cost control.

[0003] However, traditional cutting operations often rely on manual marking and positioning, resulting in low cutting accuracy and efficiency. Furthermore, pipes are prone to shaking during cutting, leading to cut deviations and potentially causing safety accidents. In addition, existing clamping tools are often ill-suited for pipes of different diameters and materials, lacking versatility and failing to meet the demands of complex and variable working conditions.

[0004] Therefore, there is an urgent need for a pipe cutting positioning and fixing device with a reasonable structure, convenient operation, and strong adaptability to improve cutting accuracy and work efficiency, and ensure the safety and stability of the construction site. Summary of the Invention

[0005] This invention addresses the problems of poor accuracy, low efficiency, and insufficient safety in traditional pipe cutting caused by reliance on manual positioning and unstable clamping. It provides a pipe fixing device that can be adapted to fix pipes of different diameters, thereby improving cutting accuracy and safety.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: A pipe fixing device includes a base for supporting a pipe and the pipe fixing device. The base is provided with a support frame, a pry bar, a fixing plate and a height adjustment device. The middle part of the pry bar is rotatably mounted on the support frame, which is fixed to the base. One end of the pry bar is the operating end and the other end is the fixed end. The operating end is equipped with a height adjustment device for adjusting the height of the operating end relative to the base. The fixed end is rotatably mounted with a fixing plate, which is adapted to the pipe and together with the base forms a clamping space for clamping the pipe. Using the support frame as a fulcrum, the pry bar forms a lever structure on the base. The distance between the operating end and the base is adjusted by a height adjustment device, thereby controlling the height of the clamping space to clamp and fix pipes of different diameters. This solves the problem of a single clamp being incompatible with different pipe diameters and reduces safety risks during the cutting process.

[0007] Furthermore, the height adjustment device includes a screw, and the operating end of the pry bar has a threaded hole and is sleeved onto the middle of the screw through the threaded hole. Rotating the screw bar adjusts the position of the operating end of the pry bar.

[0008] Furthermore, one end of the screw is provided with a handle, and the other end is provided with a pad that contacts the base. The handle is used to apply torque, and the pad is used to increase the contact area with the base to prevent excessive local pressure from damaging the base.

[0009] Furthermore, the handle is in the shape of a straight rod, and the pad is hemispherical. Regardless of the screw's tilt, it maintains stable contact with the base plane, allowing the screw to rotate easily under pressure.

[0010] Furthermore, the support frame is inverted U-shaped, with both ends fixed to the base. A pivot is fitted around the outer periphery of the middle section of the support frame, and the pry bar is fixed to the bottom of the pivot. This provides a stable fulcrum for the pry bar, ensuring uniform and controllable clamping force.

[0011] Furthermore, a connecting rod is horizontally provided at the fixed end of the pry bar, and the fixing plate includes a leaf plate, the outer side of which is sleeved on the connecting rod through a tube. The leaf plate is in contact with the pipe and is used to fix the upper surface of the pipe.

[0012] Furthermore, the fixing plate includes two straight blades forming an L-shape, with their inner surfaces tangentially contacting the outer surface of the pipe. The tangential contact between the two blades and the pipe allows for the compression of pipes of different diameters.

[0013] Furthermore, the connecting rod has an external thread on its outer periphery, and the inner wall of the tube has an internal thread that mates with the external thread. This enhances the stability of the connection between the fixing plate and the pry bar, preventing pipe swaying.

[0014] The beneficial effects of this utility model through the above technical solution are as follows: This utility model is equipped with a support frame, a pry bar, a fixing plate, and a height adjustment device, forming a lever structure on the base. By adjusting the tilt angle of the pry bar through the height adjustment device, the pipe is clamped between the fixing plate and the base, effectively preventing the pipe from rolling or shifting during the cutting process and significantly improving the cutting accuracy.

[0015] This invention uses a height adjustment device to control the size of the clamping space, thereby safely and stably fixing pipes of different diameters, solving the problems of poor versatility and low adaptability of a single clamp; at the same time, it is convenient and flexible to operate, and can quickly complete the clamping and release of pipes without complicated procedures or additional tools, which significantly improves work efficiency and reduces labor intensity.

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-3 As shown, this embodiment provides a pipe fixing device, including a base 1, on which a support frame 2, a pry bar 3, a fixing plate 52 and a height adjustment device are provided.

[0018] The pry bar 3 is rotatably mounted on the support frame 2, which is fixed to the base 1. One end of the pry bar 3 is an operating end, and the other end is a fixed end. The operating end is equipped with a height adjustment device to adjust the height of the operating end relative to the base 1. The fixed end is rotatably equipped with a fixing plate 52, which is adapted to the pipe 6 and together with the base 1 forms a clamping space for holding the pipe 6. With the support frame 2 as a fulcrum, the pry bar 3 forms a lever structure on the base 1. By adjusting the distance between the operating end and the base 1 through the height adjustment device, the height of the clamping space is controlled to clamp and fix pipes 6 of different diameters.

[0019] The height adjustment device includes a screw 41. The operating end of the pry bar 3 has a threaded hole 31 and is sleeved on the middle of the screw 41 through the threaded hole 31. Rotating the screw 41 can adjust the position of the operating end of the pry bar 3 on the screw 41, thereby adjusting the height of the operating end. For ease of operation, one end of the screw 41 is provided with a handle 42 for applying torque, and the other end is provided with a pad 43 that contacts the base 1.

[0020] Specifically, the handle 42 is in the shape of a straight rod, and the middle part of the handle 42 is vertically fixed to the top of the screw 41. Anti-slip rubber strips are provided on the gripping parts on both sides of the handle 42.

[0021] To facilitate the rotation of the screw 41, the pad 43 is hemispherical. When the screw 41 is tilted, the contact point moves from the apex of the arc to the side, so that the screw 41 can have a stable contact with the plane of the base 1 no matter how it is tilted, which enhances the stability of the structure and allows the screw 41 to rotate easily under pressure.

[0022] The middle part of the pry bar 3 is fixed to the support frame 2 via a pivot 21. In one possible implementation, the support frame 2 is inverted U-shaped, with both ends fixed to the base 1. The pivot 21 is sleeved on the outer periphery of the middle part of the support frame 2, and the pry bar 3 is fixed to the bottom of the pivot 21. In this embodiment, both the pry bar 3 and the pivot 21 are made of metal. The pry bar 3 is directly welded to the bottom of the pivot 21. By rotating the screw 41, the pry bar 3 drives the pivot 21 to rotate relative to the support frame 2.

[0023] The fixed end of the pry bar 3 is horizontally provided with a connecting rod 51. The outer periphery of the connecting rod 51 is provided with external threads. The fixing plate 52 includes two blades. The blades are straight and the two blades form an L-shape. Their inner surfaces can tangentially contact the outer surface of the pipe 6. The outer side of the blades is sleeved on the connecting rod 51 through a tube 53. The inner wall of the tube 53 is provided with an internal thread that mates with the external threads on the outer periphery of the connecting rod 51.

[0024] In use, hold handle 42 and rotate screw 41 to move the operating end of pry bar 3 downward and lift the fixed end away from the operating end upward, thereby moving the fixed plate 52 away from the base 1 and increasing the height of the clamping space formed between the two; place pipe 6 between fixed plate 52 and base 1, rotate screw 41 in the opposite direction to move the operating end of pry bar 3 upward and press the fixed end downward. When the two plates of fixed plate 52 are pressed against the outer circumference of pipe 6, the operating end of pry bar 3 can no longer move upward, thereby firmly clamping pipe 6 between fixed plate 52 and base 1.

[0025] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
