[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-7 The utility model provides a technical solution for a water purification equipment pipeline connection component: it includes an inner tube 1, an outer tube 2 and a sliding insert 3, the inner tube 1 and the outer tube 2 are coaxial, and a guide slide is formed between the two for the sliding insert 3 to slide, wherein the sliding insert 3 is slidably connected to the inner tube 1 and the outer tube 2 respectively, when the water purification equipment pipeline connection component is docked with the water pipe, the sliding insert 3 can be moved left and right to realize the extension and retraction of the sliding insert 3, that is, to control the overall length of the pipeline connection component, so as to achieve the effect of docking the water purification equipment pipeline connection component with the water pipe.

[0029] A preceding seal 4 is provided in the guide slide and is continuously in contact with the end of the sliding insert 3, thereby playing a sealing role and preventing the pipe connection assembly from leaking. A subsequent seal 6 is provided between the outer sleeve 2 and the sliding insert 3 to enhance the sealing performance, which can further play a role in sealing the pipe connection assembly and ensure the sealing performance of the pipe connection assembly.

[0030] A balancing member for maintaining the stability of the preceding seal 4 is also provided in the guide slide. When the sliding insert 3 telescopes and slides in the guide slide, the preceding seal 4 will continue to fit with the end of the sliding insert 3. Through the provided balancing member, the preceding seal 4 can move smoothly on a predetermined track along with the movement of the sliding insert 3, thereby effectively preventing the preceding seal 4 from being skewed and affecting the sealing of the device.

[0031] The outer sleeve 2 is provided with a locking member 5 for locking the state of the sliding insert 3. After the sliding insert 3 is moved left and right to realize the extension and retraction of the sliding insert 3, the sliding insert 3 can be fixed by the provided locking member 5.

[0032] A subsequent sealing member 6 is further provided between the locking member 5 and the sliding insert 3. The subsequent sealing member 6 can further seal the pipeline connection assembly, thereby ensuring the sealing performance of the pipeline connection assembly.

[0033] Specifically, the locking member 5 includes a locking plate 51 uniformly fixed to the end of the outer sleeve 2. The locking plate 51 and the outer sleeve 2 are integrally formed to increase the sealing performance of the pipeline connection assembly. These locking plates 51 are circumferentially arranged along the end wall of the outer sleeve 2, and a clamping area is formed between these locking plates 51. The inner tube 1 extends into the clamping area, so that a locking slideway connected to the guide slideway is formed between the locking plate 51 and the inner tube 1. The sliding insert 3 is slidably connected to the inner wall of the locking slideway. When the sliding insert 3 is extended into the clamping area and is located between the locking plate 51 and the inner tube 1, the locking plate 51 can clamp the sliding insert 3 to fix the sliding insert 3.

[0034] Specifically, a locking ring 52 is screwed onto the outer walls of several locking plates 51 . As the locking ring 52 is rotated, the locking ring 52 moves along the outer wall of the locking plate 51 toward the end of the locking plate 51 . The locking plate 51 is squeezed by the inner wall of the locking ring 52 to clamp the sliding cannula 3 .

[0035] Specifically, the side walls of the locking plate 51 close to the inner tube 1 are provided with arc grooves, the arc grooves are interconnected to form anti-slip ring grooves, and anti-slip rubber rings 53 are embedded in the anti-slip ring grooves, wherein the outer wall of the sliding insert 3 and the inner wall of the anti-slip rubber ring 53 slide tightly against each other, and as the locking plate 51 clamps the sliding insert 3, the anti-slip rubber ring 53 and the outer wall of the sliding insert 3 can fit more tightly, thereby improving the fixing effect of the sliding insert 3.

[0036] Specifically, the side walls of the locking plate 51 close to the inner tube 1 are inclined and gradually inclined toward the center as they move away from the outer sleeve 2. When the locking ring 52 is rotated to move the locking ring 52 toward the end of the locking plate 51, the locking plate 51 gradually clamps the sliding tube 3 tighter and tighter.

[0037] Specifically, the subsequent seal 6 includes a sealing ring groove 61, which is arranged on the inner wall of the outer sleeve 2, and a sealing ring 62 is embedded in the sealing ring groove 61, wherein the outer wall of the sliding tube 3 is tightly pressed against the inner wall of the sealing ring 62, further improving the sealing performance of the device.

[0038] Specifically, the preceding seal 4 includes a clamping ring 41 that slides in the guide slide, and the end of the sliding tube 3 abuts against the clamping ring 41 to seal between the inner tube 1 and the sliding tube 3. An elastic member 42 connected to the clamping ring 41 is provided in the guide slide. The elastic member 42 is a compression spring. The elastic member 42 can continuously provide an outward thrust to the clamping ring 41, so that the end of the sliding tube 3 is continuously pressed against the clamping ring 41 to further increase the sealing performance. The side wall of the clamping ring 41 is provided with a plug-in ring groove 43, and the end of the sliding tube 3 is fixedly connected with a plug-in sealing ring 44 that is plugged into the plug-in ring groove 43. After the sliding tube 3 is inserted into the guide slide, the sliding tube 3 will drive the plug-in sealing ring 44 to be inserted into the plug-in ring groove 43 to further enhance the sealing performance.

[0039] Specifically, a sealing gasket 45 is fixedly connected to the side wall of the tightening ring 41 close to the sliding cannula 3 to further enhance the sealing performance.

[0040] Specifically, the inner tube 1 and the outer tube 2 are fixed together at the end of the connecting tube 7. The connecting tube 7 connects the inner tube 1 with the water purification equipment body 10. One end of the compression spring in the preceding seal 4 is fixed to the connecting tube 7. The balance member includes a guide rod 8, which is fixed to the side wall of the clamping ring 41. The guide rod 8 passes through the connecting tube 7 and is slidably connected thereto, thereby playing a guiding role to prevent the clamping ring 41 in the preceding seal 4 from being deflected when moving with the sliding insert 3, thereby affecting the sealing of the device.

[0041] Working principle:

[0042] In actual use, when it is necessary to connect the pipe, the sliding insert 3 is inserted along the guide slide, and the sliding insert 3 is slid left and right in the guide slide to adjust the overall length of the pipe connection assembly, and then locked by the locking piece 5. The preceding seal 4 and the subsequent seal 6 provide good sealing at the guide slide and the locking piece 5 respectively, ensuring the sealing and stability of the water purification equipment pipe connection.
