The clamp 6 is sleeved on the outer wall between the end cover 3 and the connecting pipe sleeve 2, and a mounting groove 32 is provided on the middle inner wall of the clamp 6. The mounting groove 32 is used to accommodate the connecting part between the end cover 3 and the connecting pipe sleeve 2 to ensure that the clamp 6 can be installed correctly. The outer wall between the end cover 3 and the connecting pipe sleeve 2 is provided on the inner wall of the mounting groove 32, and the front end left part of the clamp 6 is rotatably connected to a threaded rod 66 for adjusting the position of the mounting block 65 to further improve the tightness of the connection between the front parts of the clamp 6, and the right side of the threaded rod 66 is threadedly connected to a support slot 63 to cooperate with the clamp 64 to tightly install the mounting block 65 between the front parts of the clamp 6.

[0032] Reference Figure 1 、 Figure 2 and Figure 3A sealing assembly is provided between the end cap 3 and the connecting pipe sleeve 2. The sealing assembly includes a circular groove 31 that provides space for the movement of the sealing gasket 33 and a sealing gasket 33 that increases the sealing performance of the connection. The sealing gasket 33 is set to a silicone material, which has good high and low temperature resistance and a certain chemical corrosion resistance. It is suitable for water treatment systems that are in direct contact with food or drinking water. The circular groove 31 is opened at the bottom end of the end cap 3, and the top of the connecting pipe sleeve 2 is provided with a circular groove 2 35 for accommodating the sealing gasket 33 and the spring 1 34. The sealing gasket 33 slides on the inner wall of the circular groove 2 35, and the bottom end of the sealing gasket 33 is fixedly connected with a spring The spring 1 34 is connected to the end cover 3 through the connecting sleeve 2 to squeeze the sealing gasket 33 and the spring 1 34. The reverse force of the spring 1 34 is squeezed so that the sealing gasket 33 is always squeezed tightly against the top inner wall of the circular groove 1 31 when inserted into the circular groove 1 31, thereby increasing the sealing performance of the connection between the connecting sleeve 2 and the end cover 3, and further increasing the anti-pollution effect. The other end of the spring 1 34 is arranged on the bottom inner wall of the circular groove 2 35, and the bottom end of the spring 1 34 is snap-fitted to the bottom inner wall of the circular groove 2 35, so that the spring 1 34 and the sealing gasket 33 can be easily replaced, and the upper part of the sealing gasket 33 is inserted into the inner wall of the circular groove 1 31.

[0033] Reference Figure 1 、 Figure 2 and Figure 3 The top of the block 64 is fixedly connected to the inner wall of the front right part of the clamp 6, and the top of the block 64 is fixedly connected to the spring 2 62, which pulls the disc upward to drive the guide rod 61 and the block 64 to move and squeeze the spring 2 62, so that the block 64 slides out of the slot 63, releasing the limit of the clamp 6, and at the same time, the reverse force of the spring 2 62 squeezed by the block 64 and the guide rod 61 is reset, so that the block 64 is stuck in the slot 63 to limit the installation block 65.

[0034] Furthermore, the second spring 62 is fixedly connected to the top of the inner wall of the right front end of the clamp 6, and the second spring 62 is sleeved between the outer wall of the guide rod 61 and the inner wall of the right front end of the clamp 6. The top of the mounting block 65 is provided with a slot 63 and multiple groups are provided. The slots 63 are provided with multiple groups. After the connecting pipe sleeve 2 and the end cover 3 are connected through the clamp 6, the front of the clamp 6 can be directly pressed at this time, so that the inclined surface of the block 64 is squeezed by the clamp 6 and moves upward to squeeze the second spring 62, so that the block 64 is reset by the reverse force of the squeezing of the second spring 62 and is stuck in the corresponding slot 63, thereby fixing the clamp 6. By limiting the front, the connecting pipe sleeve 2 can be quickly connected to the end cover 3. The left side of the bottom end of the block 64 is set to an inclined surface, and the block 64 is inserted into the inner wall of the slot 63. The slot 63 is adapted to the block 64. The right side of the mounting block 65 is fixedly connected with a baffle. By setting the baffle, it can be directly connected to the mounting block 65 by rotating the threaded rod 66, and then the mounting block 65 is moved with the baffle to directly squeeze the front right part of the clamp 6, so that the front left and right parts of the clamp 6 are close to the limit. The top of the guide rod 61 is fixedly connected with a disc near the top of the clamp 6. The guide rod 61 can be easily moved by setting the disc.

[0035] Working principle: When in use, align the end cover 3 with the connecting pipe sleeve 2 and tighten it. At this time, the clamp 6 is sleeved between the end cover 3 and the connecting pipe sleeve 2, so that the end cover 3 and the connecting pipe sleeve 2 are clamped in the installation groove 32. At this time, after the threaded rod 66 is threadedly connected with the mounting block 65, the front end of the clamp 6 is directly pushed, so that the front right part of the clamp 6 drives the clamping block 64 to move, so that the inclined surface of the clamping block 64 is squeezed by the mounting block 65 and then moves upward to squeeze the second spring 62. After the end cover 3 and the connecting pipe sleeve 2 are tightly connected through the clamp 6, the reverse force of the squeezing of the second spring 62 causes the clamping block 64 to reset and get stuck in the corresponding card The left and right front ends of the clamp 6 can be limited in the groove 63. At this time, the installation limit can be quickly performed without the use of tools, which improves the convenience of installation and disassembly. At the same time, the tightness of the connection can be further adjusted by rotating the threaded rod 66, thereby improving the connection effect. When disassembly is required, the threaded rod 66 is directly rotated to move out of the left side of the mounting block 65, and the limit of the left and right front ends of the clamp 6 can be directly released. At this time, the clamp 6 can be directly removed, and then the end cover 3 and the connecting pipe sleeve 2 can be removed. Installation and disassembly can be quickly performed without tools, and the operation is convenient and quick to install, thereby improving maintenance efficiency.

[0036] When the end cover 3 is connected to the connecting pipe sleeve 2, the sealing gasket 33 is aligned with the circular groove 1 31 and then slides into the circular groove 1 31. At this time, the sealing gasket 33 is squeezed by the top of the inner wall of the circular groove 1 31, so that the sealing gasket 33 squeezes the spring 1 34 in the circular groove 2 35. When the connecting pipe sleeve 2 is aligned and connected with the end cover 3, the reverse force of the spring 1 34 can make the sealing gasket 33 always tightly attached to the top of the inner wall of the circular groove 1 31, thereby increasing the tightness of the connection between the end cover 3 and the connecting pipe sleeve 2, thereby preventing raw water or treated water from leaking at the connection, and further improving the anti-pollution effect.
