Description

Technical Field

[0001] This utility model belongs to the field of pipe bending technology, specifically a fixing clamp suitable for plastic pipe bending. Background Technology

[0002] Plastic pipe bends need to be secured during processing to ensure the pipe does not move or deform when bent. Clamping provides a stable support point, preventing the pipe from shifting during bending, thus ensuring the accuracy and consistency of the bend.

[0003] In existing technologies, pipe bending clamps are generally made of metal. However, there are significant differences in the material properties of plastic and metal. Plastic has high elasticity and toughness, while metal is relatively hard and brittle. This difference in material properties makes plastic pipe bending easy to deform or break when subjected to strong clamping by metal clamps, because plastic cannot withstand the large pressure applied by metal clamps. Therefore, it is necessary to design a pipe bending clamp suitable for plastic pipe bending to solve the above problems. Summary of the Invention

[0004] This utility model aims to provide a pipe bending fixing clamp, which is suitable for fixing and supporting plastic pipes. It will not damage the surface of the plastic pipe, will not cause cross-sectional deformation of the plastic pipe, and the support position and support height are adjustable. It is suitable for pipes of different shapes and sizes and is easy to operate.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pipe bending fixing clamp, comprising:

[0007] A workbench, the workbench comprising an internal cavity in which an electromagnet is installed;

[0008] A slide groove that penetrates the upper surface of the worktable and communicates with the cavity of the worktable;

[0009] The I-shaped wheel is slidably connected to the slide groove through the groove portion in its I-shaped cross section. The upper end of the I-shaped wheel is located outside the worktable, and the lower end of the I-shaped wheel is located in the cavity of the worktable and above the electromagnet.

[0010] A vertical sleeve, the lower end of which is connected to the upper end of the I-shaped wheel, and a threaded hole coaxial with the vertical sleeve is opened on the upper end face of the vertical sleeve. A threaded rod is installed in the threaded hole, and at least a part of the threaded rod is located on the outside of the vertical sleeve.

[0011] A connecting rod, the lower end of which is connected to the upper end of a threaded rod;

[0012] A fastening cap, which is located between the vertical sleeve and the connecting rod and is connected to the portion of the threaded rod located outside the vertical sleeve through its own threaded through hole;

[0013] An arc-shaped pad, the outer convex surface of which is connected to the upper end of the connecting rod, and the inner concave surface of the arc-shaped pad facing upward to form the placement area of ​​the bent tube;

[0014] The hook and loop fasteners are strip-shaped, with one end of each of the two fasteners fixed to a connecting rod and the other end being free. The lengths of the two fasteners are such that when they are attached, the concave surface of the arc-shaped pad is located within the closed area formed by the two fasteners.

[0015] As one option, the pipe bending fixture also includes a U-shaped bracket, which is connected to the lower end face of the workbench, with the U-shaped opening side of the U-shaped bracket away from the workbench.

[0016] As one embodiment, the slide includes a first slide and a second slide that are perpendicular to each other.

[0017] As one solution, a bending pipe fixing unit is composed of an I-shaped wheel, a vertical sleeve, a connecting rod, a fastening cap, an arc-shaped pad, and two Velcro straps. Multiple bending pipe fixing units are installed at different positions in the slide groove through their respective I-shaped wheels to form multiple bending pipe fixing positions.

[0018] As one option, the convex surface of the arc-shaped pad is connected to the threaded hole at the upper end of the connecting rod via a cylinder with external threads.

[0019] As one option, the concave surface of the arc-shaped pad is provided with an arc-shaped rubber pad block.

[0020] As one option, the Velcro is provided with a silicone pad.

[0021] In this invention, by setting up an electromagnet, a sliding groove, an I-shaped wheel, a vertical sleeve, a threaded rod, and a fastening cap, the height and horizontal position of multiple arc-shaped pads are adjusted so that they can be moved to a suitable support position to support the bent pipe, while simultaneously fixing the position of multiple I-shaped wheels; by setting up a connecting rod, a cylinder, an arc-shaped pad, an arc-shaped rubber pad, a first Velcro fastener, a second Velcro fastener, a silicone pad, and a hook surface, the plastic bent pipe is fixed on multiple arc-shaped rubber pads.

[0022] Compared with existing technologies, this utility model provides a clamp for fixing bent pipes, especially suitable for bent pipes made of plastic. It can provide stable support and fastening for plastic bent pipes, preventing them from shifting. The clamp's support height and position are adjustable, thus adapting to the support and fixing of bent pipes of different shapes and sizes. When the electromagnet is energized, the I-shaped wheel is attracted by the electromagnet, ensuring the support position is fixed. When the electromagnet is de-energized, the I-shaped wheel can slide in the groove to adjust the support position. The threaded engagement of the threaded rod and the vertical sleeve adjusts the support height. The combination of Velcro and the arc-shaped pad facilitates fixing the bent pipe, preventing its shifting, and is easy to disassemble and install. The force is adjustable, minimizing damage to the surface of the plastic bent pipe and preventing deformation of the pipe's cross-section due to excessive binding force. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. However, it should not be construed that the scope of the subject matter of the present invention is limited to the following embodiments. Any modifications, substitutions and alterations made based on ordinary technical knowledge and conventional means in the art without departing from the above-described technical concept of the present invention are included within the scope of the present invention.

[0028] like Figures 1-3 As shown, this utility model discloses a pipe bending fixing clamp, which is mainly composed of U-shaped bracket 1, workbench 2, strip electromagnet 3, slide groove 4, I-shaped wheel 5, vertical sleeve 6, threaded rod 7, fastening cap 8, connecting rod 9, cylinder 10, arc-shaped pad 11, arc-shaped rubber pad 12, first hook and loop fastener 13, second hook and loop fastener 14, silicone pad 15 and other components.

[0029] The top of the U-shaped bracket 1 is fixedly connected to a hollow workbench 2. Inside the workbench 2, a strip electromagnet 3 is fixedly connected. The model and specifications of the strip electromagnet 3 can be selected according to actual needs. The outer wall of the workbench 2 has a wire hole. The strip electromagnet 3 generates a large magnetic field after it is running.

[0030] A bar electromagnet 3 has a sliding I-shaped wheel 5 at its top. The I-shaped wheel 5 is made of magnetic material. A groove 4 is provided on the top of the worktable 2. The inner wall of the groove 4 is slidably connected to the outer wall of the I-shaped wheel 5. The I-shaped wheel 5 can rotate through the groove 4 (i.e., the I-shaped wheel 5 rotates on its own), adjusting the rotation angle of the arc-shaped pad 11. A vertical sleeve 6 is fixedly connected to the top of each I-shaped wheel 5, and the I-shaped wheel 5 drives the vertical sleeve 6 to move. The groove 4 is used to assist the movement of the I-shaped wheel 5 (the grooved part of the I-shaped cross-section of the I-shaped wheel 5 matches the groove 4) and prevent it from disengaging from the groove 4.

[0031] The top of the vertical sleeve 6 is provided with an adjustment mechanism, which includes a threaded rod 7. The inner wall of the vertical sleeve 6 is threadedly connected to the outer wall of the threaded rod 7. The threaded rod 7 causes the connecting rod 9 to rise and fall through the vertical sleeve 6. The outer wall of the threaded rod 7 is threadedly fitted with a fastening cap 8, and the bottom of the fastening cap 8 is pressed against the top of the vertical sleeve 6.

[0032] Each threaded rod 7 is fixedly connected to a connecting rod 9 at its top. Each connecting rod 9 has a threaded hole at its top. Each threaded hole has a cylinder 10 threadedly connected to its inner wall. Each cylinder 10 has an arc-shaped pad 11 fixedly connected to its top. The arc-shaped pad 11 can be rotated to disengage the cylinder 10 from the threaded hole, forming a detachable installation. This allows for the replacement of arc-shaped pads 11 of different sizes to support bent pipes of different thicknesses. An arc-shaped rubber pad 12 is fixedly connected to the top of the arc-shaped pad 11.

[0033] The top of the vertical sleeve 6 is provided with a fixing mechanism, which includes a silicone pad 15. The silicone pad 15 and the arc-shaped rubber pad 12 are made of elastic material to increase the friction between them and the plastic bend. The outer wall of the connecting rod 9 is fixedly connected to the first end of the first hook and loop fastener 13 and the first end of the second hook and loop fastener 14. The second end of the first hook and loop fastener 13 and the second end of the second hook and loop fastener 14 are respectively free ends. The outer wall of the silicone pad 15 is fixedly connected to the outer wall of the first hook and loop fastener 13. The outer wall of the second hook and loop fastener 14 is provided with a hook surface 16, and the outer wall of the first hook and loop fastener 13 is provided with a velvet surface.

[0034] The working principle of the pipe bending fixture: During use, according to the required support height, rotate the fastening cap 8 to release the squeezing pressure between it and the vertical sleeve 6. Then, rotate the threaded rod 7 through the vertical sleeve 6 to raise and lower the connecting rod 9. Rotate the fastening cap 8 to press it against the top of the vertical sleeve 6 to prevent the threaded rod 7 from rotating easily. Move the I-shaped wheel 5 in the slide groove 4 to change the horizontal position of the arc-shaped pad 11 and move it to a suitable support position. The strip electromagnet 3 generates a magnetic field to fix the magnetic I-shaped wheel 5 in a uniform position. Then, place the two ends of the plastic pipe bending tube on the arc-shaped rubber pads 12 on both sides of the workbench 2. Then, support the middle position of the plastic pipe bending tube with the middle arc-shaped rubber pad 12. Wrap the first Velcro 13 around the plastic pipe bending tube from top to bottom. Then, the loop side and the hook side 16 of the second Velcro 14 are bonded together to fix the plastic pipe bending tube on the arc-shaped rubber pad 12, so as to facilitate the subsequent equipment to process the plastic pipe bending tube from top to bottom. The above description is merely one specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
