Description

Technical Field

[0001] This utility model relates to the field of straightening technology, and in particular to a straightening device for a press-fit pipe. Background Technology

[0002] In industries such as power and communications, crimped pipes are commonly used to connect components such as conductors. However, improper operation or other reasons during the construction process can cause the crimped pipes to bend or deform. After long-term operation, cracks may appear. If they are not straightened, they will become permanent defects. In power transmission lines, this can easily lead to safety hazards such as conductor strand breakage at the pipe opening. Therefore, a crimped pipe straightening device is needed.

[0003] Traditional crimping tube straightening devices typically require fixing the crimping tube during use to prevent it from loosening and causing scratches, wear, or other damage during the straightening process. However, the existing fixing methods are cumbersome and difficult to adapt to different specifications of crimping tubes quickly and conveniently, thus affecting operational efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantages of inconvenience in fixing the crimped pipe during the straightening process and low operating efficiency. To this end, we propose a crimped pipe straightening device.

[0005] To achieve the above objectives, this application adopts the following technical solution: a pipe straightening device, comprising a base plate, a straightening component installed on the top of the base plate, support plates fixed at both ends of the top of the base plate, a fixing rod slidably installed inside the support plate, an upper clamping plate fixed at the bottom of the fixing rod, support seats fixed at both ends of the top of the base plate, a lower clamping plate fixed at the top of the support seats, the lower clamping plate corresponding to the position of the support seats, a housing fixed at the top of the support plate, a screw threaded to the side wall of the housing, a knob fixed at one end of the screw, a limit block fixed at the end of the screw inside the housing, a horizontal plate slidably connected inside the housing, an insert plate fixed to one side of the horizontal plate, and multiple slots for cooperating with the insert plates arranged longitudinally on one side of the fixing rod.

[0006] Preferably, springs are fixed at both ends of the inner wall of the housing, and the other end of the springs is fixed to the cross plate.

[0007] Preferably, the limiting block is elliptical in shape.

[0008] Preferably, limit rods are fixed on both sides inside the housing, and grooves that cooperate with the limit rods are provided at both ends of the cross plate.

[0009] Preferably, a gasket is fitted on the surface of the screw, and the gasket is made of rubber.

[0010] Preferably, the inner sides of both the upper and lower clamping plates are fixed with elastic layers.

[0011] Preferably, casters are provided at the four corners of the bottom of the base plate via connecting rods, and a brake device is provided on the top of the casters.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by placing the crimping tube between the upper and lower clamping plates, and then turning the knob, the screw and the limiting block fixed thereto rotate, causing the limiting block to move away from the side of the horizontal plate. At the same time, the spring's rebound force pushes the horizontal plate, causing the insert plate to disengage from the slot, thus releasing the fixing rod. Subsequently, the user can adjust the height of the fixing rod up and down, thereby adjusting the distance between the upper and lower clamping plates to facilitate the clamping and fixing of crimping tubes of different specifications. This prevents the crimping tube from loosening during the straightening process, causing scratches, wear, and other damage, improving the straightening effect. At the same time, the operation is simple and convenient, improving work efficiency. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] Reference Figures 1-4As shown, this utility model provides a technical solution: a pipe straightening device, including a base plate 1, a straightening component 2 installed on the top of the base plate 1, support plates 3 fixed at both ends of the top of the base plate 1, a fixing rod 4 slidably installed inside the support plate 3, an upper clamping plate 5 fixed at the bottom of the fixing rod 4, support seats 6 fixed at both ends of the top of the base plate 1, a lower clamping plate 7 fixed at the top of the support seat 6, the lower clamping plate 7 corresponding to the position of the support seat 6, a housing 8 fixed at the top of the support plate 3, a screw 9 threadedly connected to the side wall of the housing 8, a knob 10 fixed at one end of the screw 9, a limit block 11 fixed at the end of the screw 9 inside the housing 8, a horizontal plate 12 slidably connected inside the housing 8, an insert plate 13 fixed on one side of the horizontal plate 12, and multiple openings on one side of the fixing rod 4 corresponding to the insert plate 1. The slots 14 used in conjunction with the 3 are arranged longitudinally. Both ends of the inner wall of the housing 8 are fixed with springs 15. The other end of the springs 15 is fixed to the horizontal plate 12. By placing the pressure tube between the upper clamping plate 5 and the lower clamping plate 7, and then turning the knob 10, the screw 9 and the limiting block 11 fixed thereto are rotated, so that the limiting block 11 is away from the side of the horizontal plate 12. At the same time, the spring force of the spring 15 pushes the horizontal plate 12 to drive the insert plate 13 out of the interior of the slot 14, thus releasing the fixation of the fixing rod 4. Then, the user can adjust the height of the fixing rod 4 up and down, thereby adjusting the distance between the upper clamping plate 5 and the lower clamping plate 7, so as to clamp and fix the pressure tubes of different specifications, avoid the pressure tubes from loosening during the straightening process, and prevent scratches, wear and other damage, thereby improving the straightening effect.

[0021] Reference Figure 4 As shown in this embodiment, the limiting block 11 is elliptical in shape. The elliptical design of the limiting block 11 can avoid excessive friction with the horizontal plate 12 during rotation, reduce the resistance during rotation, and facilitate the user to rotate the screw 9.

[0022] Reference Figure 4 As shown in this embodiment: both sides of the housing 8 are fixed with limiting rods 16, and both ends of the horizontal plate 12 are provided with grooves 17 that cooperate with the limiting rods 16. Through the structure of the limiting rods 16 and the grooves 17, the horizontal plate 12 can be limited to avoid the horizontal plate 12 from shifting during the sliding process, and ensure that the horizontal plate 12 is more stable during the sliding process.

[0023] Reference Figure 4 As shown in this embodiment: a gasket 18 is fitted on the surface of the screw 9. The gasket 18 is made of rubber. The design of the rubber material of the gasket 18 can increase the firmness between the knob 10 and the housing 8 and prevent loosening during the fixing process.

[0024] Reference Figure 2As shown in this embodiment, the inner sides of the upper clamping plate 5 and the lower clamping plate 7 are both fixed with elastic layers 19. The design of the elastic layers 19 can protect the crimping tube, prevent the surface of the crimping tube from being worn, and improve the service life of the crimping tube. At the same time, it can make the upper clamping plate 5 and the lower clamping plate 7 fit the surface of the crimping tube more closely, further improving the clamping and fixing effect.

[0025] Reference Figure 1 As shown in this embodiment: casters 20 are provided at the four corners of the bottom of the base plate 1 via connecting rods. A brake device 21 is provided on the top of the casters 20. The design of the casters 20 and the brake device 21 makes it easy for the user to move the device. At the same time, the brake device 21 can brake the casters 20 to prevent the device from shifting during use and ensure that the device is more stable during use.

[0026] Working principle: The user places the crimping tube between the upper clamping plate 5 and the lower clamping plate 7, then turns the knob 10 to rotate the screw 9 and the fixed limiting block 11, causing the limiting block 11 to move away from the side of the horizontal plate 12. Simultaneously, the spring 15's rebound force pushes the horizontal plate 12, causing the insert plate 13 to disengage from the slot 14, thus releasing the fixing rod 4. The user can then adjust the height of the fixing rod 4 to adjust the distance between the upper clamping plate 5 and the lower clamping plate 7, facilitating the clamping and fixing of crimping tubes of different specifications. This prevents the crimping tube from loosening during straightening, avoiding scratches, wear, and other damage, and improving the straightening effect. The elliptical design of the limiting block 11 prevents excessive friction with the horizontal plate 12 during rotation, reducing rotational resistance and facilitating the user's rotation of the screw 9. The structure of 16 and groove 17 can limit the horizontal plate 12, preventing it from shifting during sliding and ensuring its stability. The rubber material design of the gasket 18 increases the firmness between the knob 10 and the housing 8, preventing loosening during fixing. The elastic layer 19 protects the pressure tube, preventing wear on its surface and extending its service life. It also allows the upper clamping plate 5 and lower clamping plate 7 to fit more closely to the surface of the pressure tube, further improving the clamping and fixing effect. The design of casters 20 and brake device 21 facilitates user movement of the device, while the brake device 21 brakes the casters 20, preventing the device from shifting during use and ensuring its stability.
