[0002] The main component of PVC pipe is polyvinyl chloride, which is generally used to transport gas or liquid substances. It has good heat resistance, toughness, and ductility, and has a very broad application prospect. During the production process of PVC pipes, it is usually necessary to cut the PVC pipes pulled by a tractor according to customer requirements and other situations to meet different customer needs.

The device includes a measuring device, a fixing device, etc. Among them, the fixing device is crucial. It can clamp the PVC pipe to prevent movement or shaking during the cutting process, thereby ensuring the cutting accuracy.
[0004] Before cutting the PVC pipe, the PVC pipe fixed-length cutting device usually fixes the pipe with bolts for measurement and cutting. It is found in use and production that tightening the bolts with tools is required for bolt fixing, making the installation process relatively cumbersome and time-consuming.

[0009] Preferably, a friction pad is fixedly connected to the side wall of the second sliding groove; a plurality of friction pads are arranged on the second sliding groove; adding the friction pad can increase the contact area between the second slider and the second sliding groove, thereby increasing the friction force and improving the stability of the second slider after adjustment.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] The following gives specific embodiments.
[0025] As Figures 1 to 5 shown, a PVC pipe fixed-length cutting device described in an embodiment of the present utility model includes a base 1, and a pair of connecting frames 11 are fixedly connected to the top of the base 1; a cover plate 12 is arranged on the top of the connecting frame 11; a pair of clamping bodies 13 are fixedly connected to the bottom of the cover plate 12; a pair of fixing blocks 14 are fixedly connected to the side wall of the clamping body 13; a clamping groove 15 is opened on the top of the connecting frame 11; a pair of first sliding grooves 16 are opened on the side wall of the clamping groove 15; an elastic block 18 is arranged inside the first sliding groove 16; a fixing port 17 is opened inside the connecting frame 11; during work, first place the pipe on the surface of the fixing port 17, and then cover the cover plate 12 above the pipe. At this time, the clamping body 13 will enter the inside of the clamping groove 15 as the cover plate 12 moves. Subsequently, the fixing block 14 will contact the elastic block 18. As the clamping body 13 continues to descend, the fixing block 14 will exert a force on the elastic block 18. Due to the slight flexibility of the elastic block 18, the fixing block 14 can pass through the obstruction of the elastic block 18. When the fixing block 14 reaches the bottom of the clamping groove 15, the elastic block 18 will be above the fixing block 14 and the upper surface of the fixing block 14 will closely fit the lower surface of the elastic block 18. At this time, the effect of fixing the cover plate 12 is achieved. Since the connecting frame 11 is fixed and the elastic block 18 inside the connecting frame 11 fixes the cover plate 12, the connecting frame 11 and the cover plate 12 achieve the effect of fixing the pipe. Subsequently, a measuring tool can be used to measure the pipe length and then perform the cutting work; through the cooperation of the fixing block 14 and the elastic block 18, the pipe can be quickly fixed, reducing the working process of fixing the pipe, eliminating the cumbersome project of using tools to tighten the bolts during bolt fixing, reducing the time for fixing the pipe, and only need to combine the connecting frame 11 and the cover plate 12 after placing the pipe during installation, reducing the working time for fixing the pipe.
[0026] As Figures 4 to 5As shown, a second sliding groove 2 is formed inside the connecting frame 11; the second sliding groove 2 communicates with the first sliding groove 16; a first connecting rod 25 is hinged to the side wall of the elastic block 18; the elastic block 18 is slidably connected to the first sliding groove 16; the bottom of the first connecting rod 25 is hinged to a second slider 21; the second slider 21 is slidably connected to the second sliding groove 2; the bottom of the second slider 21 is fixedly connected to a third slider 22; the third slider 22 is slidably connected to the second sliding groove 2; a slide rod 24 is fixedly connected to the side wall of the third slider 22; a pair of third sliding grooves 23 are formed in the side wall of the connecting frame 11; the third sliding grooves 23 are slidably connected to the slide rod 24; during operation, when the pipeline needs to be taken out, the position of the elastic block 18 can be adjusted by sliding the slide rod 24 along the third sliding groove 23. When the slide rod 24 moves, the third slider 22 moves synchronously, driving the second slider 21 to move up and down. When the second slider 21 moves up and down, the first connecting rod 25 will adjust its angle accordingly. By adjusting the angle of the first connecting rod 25, the elastic block 18 moves forward and backward. When the slide rod 24 slides to the bottom of the third sliding groove 23, the elastic block 18 will retract into the first sliding groove 16. At this time, the fixing block 14 will not be blocked by the elastic block 18 and can easily leave the inside of the card slot 15 to take out the pipeline; by sliding the elastic block 18 to adjust the protruding length, it is easier to take out the pipeline without hard pulling, which will not damage the fixing block 14 and the elastic block 18, thus increasing the service life. Due to the flexible adjustment of the elastic block 18, the pipeline can be taken out more quickly and efficiently, reducing the disassembly working time and increasing the disassembly convenience.
[0027] As Figure 5 shown, a friction pad 3 is fixedly connected to the side wall of the second sliding groove 2; a plurality of friction pads 3 are arranged on the second sliding groove 2; during operation, when the second slider 21 slides inside the second sliding groove 2, since the friction pads 3 installed on the inner wall of the second sliding groove 2 increase the contact area, the resistance is increased. After the sliding is completed, the second slider 21 will be stuck between two of the friction pads 3 to provide stability after adjustment; installing the friction pads 3 can increase the contact area between the second slider 21 and the second sliding groove 2, thereby increasing the friction force and the stability of the second slider 21 after adjustment.
[0028] As Figures 1 to 2As shown, a second connecting rod 4 is fixedly connected to the side wall of the sliding rod 24; a plurality of telescopic rods 41 are fixedly connected to the top of the base 1; the adjacent second connecting rod 4 and telescopic rod 41 are fixedly connected; during operation, since the sliding rod 24 needs to be adjusted twice in succession when adjusting, the second connecting rod 4 can be connected to the sliding rods 24 on both sides. When adjusting the sliding rod 24, the telescopic rod 41 can be used to move the second connecting rod 4 so as to adjust the sliding rod 24 simultaneously. When the pipeline needs to be taken out, the telescopic rod 41 is pressed down so that the elastic block 18 retracts into the first chute 16; connecting the sliding rods 24 can increase convenience during adjustment. Adjusting the sliding rods 24 simultaneously can make space for the fixing blocks 14 on both sides at the same time, making it easy to enter. At the same time, the telescopic rod 41 can make the adjustment more labor-saving and reduce the adjustment time.
[0029] As Figure 3 shown, a lower sponge 5 is fixedly connected to the middle of the connecting frame 11; an upper sponge 51 is fixedly connected to the middle of the cover plate 12; during operation, when the pipeline is placed into the fixing port 17, it will be in contact with the lower sponge 5 and the upper sponge 51. At this time, when the length needs to be adjusted, it will rub back and forth, and the impurities and dust on the surface of the pipeline can be cleaned off. When the connecting frame 11 and the cover plate 12 are closed, the gap can be filled, and the contact area between the pipeline and the fixing port 17 can be increased; cleaning the surface of the pipeline can reduce the damage to the pipeline during fixation due to impurities, and at the same time, it can also reduce the influence of the presence of impurities on the fixing stability. However, using the lower sponge 5 and the upper sponge 51 to fill the gap can utilize the squeezable property to immediately recover after the pipeline is unloaded without damage.
[0030] As Figure 3 shown, an elastic plate 6 is fixedly connected to the bottom of the upper sponge 51; a groove 61 is formed inside the lower sponge 5; the elastic plate 6 and the end of the groove 61 are correspondingly arranged; during operation, after the connecting frame 11 and the cover plate 12 are combined, the two elastic plates 6 will penetrate along the shape of the groove 61 and then converge the internal impurities to the middle and then squeeze them out from the holes on the surface, reducing the impurities stored inside the lower sponge 5; the elastic plate 6 penetrating into the lower sponge 5 to clean the impurities can perform self-cleaning each time when the pipeline is fixed, reducing the subsequent cleaning working time. Since the elastic plate 6 has elasticity, it will penetrate along the shape of the groove 61 without damaging the inside of the lower sponge 5 and better cleaning the inside of the lower sponge 5.
[0031] Working principle: Place the pipe on the surface of the fixed port 17, and then cover the pipe with the cover plate 12. At this time, the clamping body 13 will enter the inside of the clamping groove 15 as the cover plate 12 moves. Subsequently, the fixing block 14 will contact the elastic block 18. As the clamping body 13 is continuously lowered, the fixing block 14 will exert a force on the elastic block 18. Due to the slight flexibility of the elastic block 18, the fixing block 14 can pass through the obstruction of the elastic block 18. When the fixing block 14 reaches the bottom of the clamping groove 15, the elastic block 18 will be above the fixing block 14 and the upper surface of the fixing block 14 will closely fit the lower surface of the elastic block 18. At this time, the effect of fixing the cover plate 12 is achieved. Since the connecting frame 11 is fixed and the elastic block 18 inside the connecting frame 11 fixes the cover plate 12, the connecting frame 11 and the cover plate 12 achieve the fixing effect on the pipe. Subsequently, the pipe length can be measured with a measuring tool and then the cutting work can be carried out; when the pipe needs to be removed, the position of the elastic block 18 can be adjusted by sliding the sliding rod 24 along the third sliding groove 23. When the sliding rod 24 moves, the third slider 22 will move synchronously therewith, thereby driving the second slider 21 to move up and down. When the second slider 21 moves up and down, the first connecting rod 25 will adjust the angle accordingly. By adjusting the angle of the first connecting rod 25, the elastic block 18 will move forward and backward. When the sliding rod 24 slides to the bottom of the third sliding groove 23, the elastic block 18 will retract into the first sliding groove 16. At this time, the fixing block 14 will not be obstructed by the elastic block 18 and can easily leave the inside of the clamping groove 15 to remove the pipe; when the second slider 21 slides in the second sliding groove 2, since the friction pads 3 installed on the inner wall of the second sliding groove 2 will increase the contact area and thus increase the resistance, after the sliding is completed, the second slider 21 will be stuck between two of the friction pads 3 to provide the stability after adjustment; since the sliding rod 24 needs to be adjusted twice in succession when adjusting, the second connecting rod 4 can be connected to both sides of the sliding rod 24. When adjusting the sliding rod 24, the second connecting rod 4 can be moved by the telescopic rod 41 to achieve simultaneous adjustment of the sliding rod 24. When the pipe needs to be removed, press down the telescopic rod 41 so that the elastic block 18 retracts into the first sliding groove 16; when the pipe is placed in the fixed port 17, it will fit with the lower sponge 5 and the upper sponge 51. At this time, when the length needs to be adjusted, it will be rubbed back and forth. At this time, the impurities and dust on the surface of the pipe can be cleaned off. When the connecting frame 11 and the cover plate 12 are closed, the gaps can be filled to increase the contact area between the pipe and the fixed port 17; when the connecting frame 11 and the cover plate 12 are combined, the two elastic plates 6 will penetrate along the shape of the groove 61 and then converge the internal impurities to the middle and then squeeze them out from the holes on the surface, reducing the impurities stored in the lower sponge 5.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model.
