[0001] The utility model relates to the technical field of plastic processing equipment, in particular to a PVC pipe fitting clamping device. Background Art

[0002] PVC pipe clamping device is an important component to ensure the installation of plastic pipe system, ensuring sealing and stability, simplifying operation and improving overall system safety and efficiency.

[0003] In the prior art, such as the Chinese patent number: CN212385310U, "A PVC pipe clamping device", includes a lower base plate and a support plate, a support plate is fixedly installed in the middle of the upper surface of the lower base plate, the left and right ends of the upper surface of the lower base plate are opened with embedded holes, and the upper part of the embedded holes is embedded with lower nuts, and the left and right ends of the upper surface of the lower base plate are fixedly installed with nesting plates, and the inside of the nesting plates is opened with telescopic grooves, and a movable inner plate is embedded in the inside of the telescopic grooves, and a support frame is fixedly installed in the middle of the upper surface of the movable inner plate, and the middle part of the support frame is rotatably connected with a guide wheel, and lower screws are inserted at the front and rear ends of the upper surface of the movable inner plate, and the top of the nesting plate is fixedly installed with a limit ring, and the lower support plate is fixedly installed below the inner wall of the limit ring, and the middle opening of the lower support plate is provided with a hidden groove. The utility model can simultaneously fix the left and right ends of the PVC pipe, the PVC pipe is not easy to shake during the processing, and it is more convenient and labor-saving to take the PVC pipe in the device.

[0004] Although the above scheme has the above advantages, the disadvantage of the above scheme is that it can only be used for the processing of PVC pipe fittings. However, most of the PVC pipe fitting clamping devices fix the PVC pipe fittings at a certain position at the workplace to facilitate the use of the PVC pipe fittings. However, under long-term fixation, the ambient temperature is also changing, causing the PVC pipe fittings to expand and contract, resulting in loosening of the fixing mechanism, causing the PVC pipe fittings to be misplaced and fall, affecting the use of the PVC pipe fittings. At the same time, when using the PVC pipe fitting clamping device, the PVC pipe fittings are not necessarily fixed horizontally, and may be fixed at a certain tilt angle. Therefore, the above scheme cannot adapt to different installation requirements and reduces installation flexibility. Utility Model Content

[0026] like Figure 1-6 As shown, a rotating shaft 15 is fixedly embedded on the inner surface of the shell 1 near the bottom, and two supporting blocks 16 are movably embedded on the outer surface of the rotating shaft 15. A chuck 17 is fixedly installed on one side of the rotating shaft 15 near the two supporting blocks 16. Two fixing blocks 18 are fixedly connected to the tops of the two supporting blocks 16. The multiple fixing blocks 18 are evenly divided into two groups. Positioning rods 19 are fixedly embedded on the inner surfaces of the two groups of fixing blocks 18. The outer surfaces of the two positioning rods 19 are movably sleeved with a clamping plate 20. The bottoms of the two clamping plates 20 are fixedly connected with a fixing plate 21, and the bottoms of the two fixing plates 21 are fixedly connected with a spring 22. A notch 23 is provided on one side of the two supporting blocks 16 near the two springs 22, so that the PVC pipe clamping device can adapt to different installation requirements and improve the installation flexibility.

[0027] like Figure 1-6 As shown, the gear ring 4 is movably embedded in the inner surface of the shell 1, and the fixing rod 6 is fixedly connected to the inner wall of the shell 1. The fixing rod 6 can position multiple gears 5 and provide a good working environment for the gears 5.

[0028] like Figure 1-6As shown, two springs 11 are fixedly connected to the inner walls of the two slide grooves 9, and two blocks 13 are movably embedded in the inner surfaces of two of the slots 14. The slide groove 9 can limit the slider 10 to avoid derailment of the slider 10 and affect the use of the equipment.

[0029] like Figure 1-6 As shown, two springs 22 are fixedly connected to the bottom inner walls of the two slots 23, and the two springs 22 are movably embedded in the inner surfaces of the two slots 23. The springs 22 can provide power for the reverse rotation of the fixed plate 21, so that the fixed plate 21 rotates in the reverse direction.

[0030] Working principle: This device is a PVC pipe clamping device. When in use, insert the PVC pipe into the housing 1, then hold the operating rod 3 with your hand, and use your fingers to move the two fixed rods 12, so that the two fixed rods 12 drive the two sliders 10 to move on the inner surface of the two slide grooves 9, and stretch the two springs 11, so that the springs 11 obtain elastic potential energy, and when the two fixed rods 12 move, they will drive the two blocks 13 to disengage the two blocks 13 from the two slots 14, and then rotate the operating rod 3 to make the operating rod 3 moves on the inner surface of the operating groove 2 on the housing 1, and drives the gear ring 4 to rotate, and the gear ring 4 drives the multiple gears 5 to make a circular motion with the multiple fixing rods 1 6 as the center, and the multiple gears 5 move the multiple fixing plates 1 8 toward the center of the housing 1 through the multiple tooth plates 7 to fix the PVC pipe, and then the fingers release the two fixing rods 2 12. At this time, the two springs 11 drive the two fixing rods 2 12 to move in the opposite direction through the two sliders 10, so that the fixing rods 2 12 drive the card block 13 to be re-carded in the card groove 14, forming Self-locking prevents the fixing mechanism from loosening, causing the PVC pipe fittings to be misplaced and fall off, and improves the user's experience. When the shell 1 needs to be rotated, two people press the two card plates 20 at the same time, so that the two card plates 20 make a circular motion with the two positioning rods 19 on the multiple fixing blocks 18 as the center, and drive the two fixing plates 21 to squeeze the springs 22 in the two notches 23, so that the two springs 22 obtain elastic potential energy. At this time, the two card plates 20 are no longer stuck on the surface of the two chucks 17, and then they are manually rotated. The shell 1 makes the shell 1 do a circular motion with the rotating shaft 15 on the two supporting blocks 16 as the center to change the angle of the shell 1. When the angle meets the process requirements, the two clamping plates 20 are no longer pressed. At this time, the two springs 22 release the elastic potential energy, so that the two fixing plates 21 drive the two clamping plates 20 to do reverse circular motion with the positioning rod 19 as the center, and clamp the two clamping plates 20 on the outer surfaces of the two chucks 17 to form a self-locking function, so that the PVC pipe clamping device can adapt to different installation requirements and improve the installation flexibility.
