[0008] As an optimal technical solution of the present invention, the bottom end of the pressure block is located inside the cylinder body, and the piston is divided into two sections, wherein the diameter value on the left side is smaller than the diameter value on the right side and the diameter value of the piston is equal to the diameter value of the connecting block.

[0009] As a preferred technical solution of the present invention, the guide sleeve is located on the left side of the piston, and the guide sleeve is located on the left side of the pressure block, and the guide sleeve, the piston and the connecting block are all coaxial.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] like Figures 1 to 5 As shown, the utility model provides a high-pressure oil pipe extrusion device, including a cylinder body 1, a slider 2 is slidably connected to the inside of the cylinder body 1, a pressure block 3 is fixedly installed above the slider 2, a piston 9 is slidably connected to the inside of the pressure block 3, a connecting block 10 is fixedly installed on the right side of the piston 9, a spring 2 11 is fixedly installed on the right side of the connecting block 10, a mounting hole 12 is opened inside the cylinder body 1, a rivet nut 13 is fixedly installed inside the mounting hole 12, a limiting clamping rod 14 is engaged inside the rivet nut 13, and a guide sleeve 15 is sleeved on the outer side of the end of the piston 9 away from the connecting block 10.

[0023] The pressure block 3 is displaced and squeezed in the direction of the guide sleeve 15 by the elastic force provided by the spring 2 11 in the direction of the connecting block 10, thereby achieving the effect of squeezing and sealing the broken high-pressure oil pipe.

[0024] Among them, a slide groove 4 is opened inside the pressing block 3, and a slider 2 5 is slidably connected inside the slide groove 4. A silicone ring sleeve 6 is fixedly installed above the slider 2 5. A telescopic rod 7 is provided inside the slide groove 4, and a spring 1 8 is sleeved on the outside of the telescopic rod 7. The spring 1 8 is fixedly connected to the slider 2 5.

[0025] The slider 2 5 slides inside the slide groove 4, so that the overall height of the silicone ring 6 can be adjusted to achieve the effect of sleeve-fitting and fixing the high-pressure oil pipe.

[0026] Among them, a placement groove 16 is opened inside the pressing block 3, and a placement groove 2 17 is opened inside the cylinder body 1. The placement groove 16 is located on the right side of the placement groove 2 17, and the placement groove 2 17 is located above the guide sleeve 15.

[0027] The diameters of placement groove 16 and placement groove 2 17 are equal. When the two ends of the high-pressure oil pipe are respectively placed in placement groove 2 17 and placement groove 1 16, the elastic force provided by spring 2 11 causes the pressure block 3 to slide inside the cylinder body 1 through slider 1 2, thereby achieving the effect of squeezing and sealing the high-pressure oil pipes at both ends.

[0028] The limiting clamping rod 14 is located on the right side of the connecting block 10 , and the limiting clamping rod 14 passes through the right end of the second spring 11 . The limiting clamping rod 14 is located inside the mounting hole 12 .

[0029] When the connecting block 10 is installed, the limiting rod 14 is passed through the right end of the spring 2 11 and then engaged with the rivet nut 13 to fix the right end of the spring 2 11. When the spring 2 11 increases its own elastic force, it can only be squeezed to the left side for fixation because the right end is fixed.

[0030] The bottom end of the pressure block 3 is located inside the cylinder body 1 , and the piston 9 is divided into two sections, wherein the diameter value of the left side is smaller than the diameter value of the right side and the diameter value of the piston 9 is equal to the diameter value of the connecting block 10 .

[0031] The main function of the piston 9 is to ensure the stability of the bottom of the pressure block 3 when it moves when the pressure block 3 slides on the outside of the piston 9, thereby preventing shaking from affecting the connectivity between the high-pressure oil pumps.

[0032] The guide sleeve 15 is located on the left side of the piston 9 and the left side of the pressure block 3 . The guide sleeve 15 is coaxial with the piston 9 and the connecting block 10 .

[0033] The guide sleeve 15 supports the piston 9 to prevent the pressure block 3 from falling off when sliding on the outside of the piston 9 .

[0034] There are two sliders 2 , both of which are located inside the cylinder body 1 , and both of which are located below the placement groove 16 .

[0035] The two sliders 1 2 slide with the inside of the cylinder 1, thereby ensuring that the upper part of the pressing block 3 has a certain stability while sliding, and limiting the upper part of the pressing block 3 to prevent the sliding displacement from offsetting.

[0036] Among them, the silicone ring sleeve 6 is arc-shaped, and the material of the silicone ring sleeve 6 is relatively soft. There are two slide grooves 4, and the two slide grooves 4 are both located inside the pressure block 3. There are two sliders 5, and the two sliders 5 are respectively located inside the two slide grooves 4. There are two telescopic rods 7 and two springs 8, and the two telescopic rods 7 and the two springs 8 are respectively fixedly connected to the pressure block 3.

[0037] The height of the silicone ring sleeve 6 is adjusted by sliding inside the two slide grooves 4 through the two sliders 2. When the oil pipe is put in, the two springs 1 8 always provide elastic force to fit the silicone ring sleeve 6 to the surface of the high-pressure oil pipe, thereby fixing the high-pressure oil pipe and preventing the high-pressure oil pipe from being displaced due to the pressure generated by the internal flow.

[0038] The working principle and use process of this utility model:

[0039] First, pull the pressing block 3 to the right to separate the placement groove 16 and the placement groove 2 17. At the same time, pull the silicone ring 6 to the upper left through the sliding action of the slider 2 5 and the slide groove 4. Then, place the two ends of the high-pressure oil pipe or water pipe into the placement groove 16 and the placement groove 2 17 respectively and align the interfaces.

[0040] At this time, since the right side of the connecting block 10 is fixedly installed with the spring 2 11, the right end of the spring 2 11 is inserted with the limit card rod 14, and the limit card rod 14 is engaged with the rivet nut 13. At this time, since the right end of the spring 2 11 is fixed by the limit card rod 14, it can only provide elastic force in the direction of the connecting block 10. At this time, the connecting block 10 will push the piston 9 in the direction of the placement groove 2 17 to squeeze, so that the placement groove 2 17 and the pipe inside the placement groove 1 16 are docked and squeezed, thereby achieving the effect of rapid extrusion installation;

[0041] Next, loosen the silicone ring 6. The silicone ring 6 will be displaced downward by the elastic force provided by the spring 1 8 through the sliding action of the slider 2 5 and the slide groove 4, so that the silicone ring 6 is sleeved on the surface of the oil pipe and contacts the oil pipe, thereby achieving the effect of fixing the oil pipe and preventing the high-pressure oil pipe from being displaced due to the pressure generated by the flow inside.

[0042] Finally, check the sealing condition of the docking to prevent oil leakage.
