[0002] Water pipes are widely used, and modern surface coolers also have inlet and outlet water pipes, filled with water or other refrigerants used for heat exchange. During disassembly, the refrigerant inside the pipes needs to be drained to prevent residue. Utility Model Content

[0003] To solve the above problems, this technical solution provides an inlet and outlet water pipe that can quickly drain water.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A water inlet and outlet pipe capable of rapid drainage, including

[0006] The pipe body has an inlet and an outlet at the end;

[0007] A drainage mechanism includes a base disposed on the other end of the pipe body, a spring disposed on the base, a piston disposed on the spring, and a rubber sleeve disposed between the outer periphery of the piston and the inner wall of the pipe body.

[0008] After water enters the pipe body through the inlet, the piston moves in the direction of compressing the spring under the action of water pressure; when water is discharged through the outlet, the piston moves closer to the outlet under the action of the spring to squeeze the water out of the pipe body.

[0009] A locking mechanism includes a locking member, wherein when the piston moves toward compressing the spring to abut against the locking member, it restricts the piston from moving further; the locking member rotates relative to the tube body to engage with the piston to lock the position of the piston.

[0010] As described above, a water inlet and outlet pipe capable of rapid drainage is provided on the pipe body with a sliding groove arranged along its circumference. The locking member includes a locking part that slides along the circumference of the pipe body and a locking pin that is inserted into the sliding groove and extends toward the piston member.

[0011] As described above, a water inlet / outlet pipe capable of rapid drainage has an outer ring, an inner ring, and a positioning groove between the outer ring and the inner ring, wherein the positioning groove is for the spring to be inserted for positioning.

[0012] As described above, in a water inlet / outlet pipe capable of rapid drainage, the outer ring is recessed with a groove. When the piston moves in the direction of compressing the spring and abuts against the locking pin, the groove makes way for the locking pin.

[0013] As described above, in a water inlet / outlet pipe that allows for rapid drainage, the annular groove sidewall is recessed with a groove, and after the locking pin enters the groove, the locking pin restricts the movement of the piston.

[0014] As described above, in a water inlet / outlet pipe capable of rapid drainage, the rubber sleeve is spaced apart from the inner wall of the piston component, the rubber sleeve is higher than the annular groove, and before the piston component moves in the direction of compressing the spring and comes into contact with the locking pin, the locking pin first contacts the rubber sleeve and provides cushioning.

[0015] As described above, in a water inlet / outlet pipe capable of rapid drainage, the piston component has a positioning ring protruding from its circumference, and the rubber sleeve is secured to the positioning ring.

[0016] As described above, in a water inlet / outlet pipe capable of rapid drainage, the piston, under the action of the spring, reaches the end of the pipe body near the outlet.

[0017] The beneficial effects of this application are:

[0018] This invention provides a water inlet and outlet pipe for rapid drainage. In use, water is injected into the pipe through the inlet, and the water pressure pushes the piston towards the compression spring. When drainage is needed, water is discharged through the outlet, and the piston moves closer to the outlet under the action of the spring to squeeze the water out of the pipe. This not only accelerates the drainage of water from the pipe but also prevents water residue. Attached Figure Description

[0021] Figure 2 yes Figure 1 Sectional view at point AA. Detailed Implementation

[0022] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0023] A water inlet and outlet pipe capable of rapid drainage, including

[0024] The pipe body 1 has an inlet 11 and an outlet 12 at the end.

[0025] The drainage mechanism 2 includes a base 21 disposed on the other end of the pipe body 1, a spring 22 disposed on the base 21, a piston 23 disposed on the spring 22, and a rubber sleeve 24 disposed between the outer periphery of the piston 23 and the inner wall of the pipe body 1.

[0026] After water enters the pipe body 1 through the inlet 11, the piston 23 is pushed to move in the direction of compressing the spring 22 under the action of water pressure; when the pipe body 1 drains water through the outlet 12, the piston 23 moves towards the outlet 12 under the action of the spring 22 to squeeze the water out of the pipe body 1.

[0027] The locking mechanism includes a locking member 3. When the piston member 23 moves in the direction of compressing the spring 22 and comes into contact with the locking member 3, the piston member 23 is restricted from moving further. The locking member 3 rotates relative to the tube body 1 to engage with the piston member 23 to lock the position of the piston member 23.

[0028] This invention provides a water inlet and outlet pipe for rapid drainage. In use, water is injected into the pipe through the inlet, and the water pressure pushes the piston towards the compression spring. When drainage is needed, water is discharged through the outlet, and the piston moves closer to the outlet under the action of the spring to squeeze the water out of the pipe. This not only accelerates the drainage of water from the pipe but also prevents water residue.

[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the tube body 1 is provided with a sliding groove 13 arranged along its circumference, and the locking member 3 includes a locking part 31 that slides along the circumference of the tube body 1, and a locking pin 32 that is inserted into the sliding groove 13 and extends toward the piston member 23. Locking or unlocking is achieved by sliding.

[0030] Furthermore, as a preferred embodiment of this solution and not a limitation, the piston component 23 is provided with an outer ring 231, an inner ring 232, and a positioning groove 233 disposed between the outer ring 231 and the inner ring 232. The positioning groove 233 is for the spring 22 to be inserted and positioned to prevent the spring from shifting.

[0031] Furthermore, as a preferred embodiment of this solution and not a limitation, the outer ring 231 is recessed with an annular groove 25. When the piston 23 moves in the direction of compressing the spring 22 to abut against the locking pin 32, the annular groove 25 makes way for the locking pin 32.

[0032] Furthermore, as a preferred embodiment of this solution and not a limitation, the annular groove 25 has a recessed groove 26 on its sidewall. After the locking pin 32 enters the groove 26, the locking pin 32 restricts the movement of the piston member 23. The groove provides limiting on both the upper and lower sides of the locking pin. Figure 2 The dotted line represents the state of the locking element when it is rotated to the locked position.

[0033] Furthermore, as a preferred embodiment of this solution and not a limitation, the rubber sleeve 24 is spaced apart from the inner wall of the piston member 23 in the tube body 1. The rubber sleeve 24 is higher than the annular groove 25. Before the piston member 23 moves in the direction of compressing the spring 22 and abuts against the locking pin 32, the locking pin 32 first contacts the rubber sleeve 24 and provides cushioning. The rubber sleeve is slightly higher than the lowest point of the annular groove.

[0034] Furthermore, as a preferred embodiment of this solution and not a limitation, the piston component 23 is provided with a positioning ring 27 protruding from its periphery, and the rubber sleeve 24 is engaged with the positioning ring 27.

[0035] Furthermore, as a preferred embodiment of this solution and not a limitation, the piston 23 reaches the end of the pipe body 1 near the outlet 12 under the action of the spring 22.

[0036] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
