[0020] 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.

[0021] like Figures 1 to 4 As shown, the utility model provides a water supply pipe with a sealing structure, comprising a pipe front section 1 and a pipe tail end 12; a ring plate 13 is fixedly connected to the middle of the pipe front section 1; a plurality of connecting plates 14 are slidably connected to the middle of the ring plate 13; a first screw sleeve 15 is threadedly connected to the middle of the plurality of connecting plates 14; a protrusion 16 is fixedly connected to the bottom of one end of the connecting plate 14 away from the ring plate 13; a limit assembly is installed in the middle of the ring plate 13;

[0022] By connecting the front section 1 and the tail end 12 of a pair of water supply pipes respectively, the end of the tail end 12 is inserted between the end of the front section 1 and the multiple connecting plates 14. After the connection is completed, the first screw sleeve 15 is rotated to move the first screw sleeve 15 to the position where the multiple connecting plates 14 are provided with protrusions 16. The first screw sleeve 15 squeezes the connecting plates 14 so that the multiple protrusions 16 are tightly fitted with the middle part of the tail end 12 and increase the friction, so that the tail end 12 will not be easily separated from the front section 1, reducing the occurrence of gaps between the tail end 12 and the front section 1, and improving the sealing of the water supply pipe connection.

[0023] like Figures 1 to 4 As shown, the limiting assembly includes a limiting plate 2 and a second screw sleeve 21; the limiting plate 2 is fixedly connected to the middle portion of the ring plate 13; the second screw sleeve 21 is rotatably connected to the middle portion of the limiting plate 2; the second screw sleeve 21 and the plurality of connecting plates 14 are threadedly matched;

[0024] After the middle part of the tube tail end 12 is squeezed by multiple protrusions 16, the second screw sleeve 21 can be rotated to drive the multiple connecting plates 14 to move in a direction away from the tube tail end 12. The multiple connecting plates 14 pull the tube tail end 12 to move the tube tail end 12 toward the tube front section 1, so that the tube tail end 12 and the tube front section 1 can fit more closely, further improving the connection sealing between the tube tail end 12 and the tube front section 1.

[0025] like Figures 1 to 4 As shown, a plurality of slots 3 are provided in the middle of the second screw sleeve 21; the plurality of slots 3 are evenly distributed in the middle of the second screw sleeve 21;

[0026] When the second screw sleeve 21 needs to be rotated, the hand needs to contact the surface of the second screw sleeve 21. The provision of multiple slots 3 can increase the friction between the hand and the second screw sleeve 21, thereby reducing the occurrence of hand slippage.

[0027] like Figures 1 to 4 As shown, the middle part of the ring plate 13 is slidably connected to the slider 4; the bottom of the slider 4 is provided with teeth that engage with multiple slots 3; the top of the ring plate 13 is slidably connected to the insertion rod 41; the middle part of the insertion rod 41 is fixedly connected to the elastic rope 42; the other end of the elastic rope 42 is fixedly connected to the top of the ring plate 13; the top of the slider 4 is provided with a slot 43;

[0028] After the second screw sleeve 21 is rotated to tightly connect the pipe tail end 12 and the pipe front section 1, the slider 4 is slid so that the bottom of the slider 4 engages with the multiple card slots 3. After the slider 4 is slid to a specified distance, the insertion rod 41 enters the slot 43 under the pull of the elastic rope 42, so that the slider 4 will no longer slide easily. At the same time, due to the engagement relationship between the slider 4 and the card slot 3, the second screw sleeve 21 will not rotate easily due to pipeline vibration, thereby reducing the occurrence of gaps between the pipe front section 1 and the pipe tail end 12 due to loosening, resulting in a decrease in sealing effect.

[0029] like Figures 2 to 4 As shown, a rubber ring 5 is fixed to the middle of the front section 1 of the tube; an inclined groove 51 is opened at the end of the tail end 12 of the tube;

[0030] When the tube tail end 12 is inserted between the tube front section 1 and the connecting plate 14, the rubber ring 5 is squeezed and deformed by the tube tail end 12. After the tube tail end 12 is connected to the tube front section 1, the rubber ring 5 will block the gap between the tube front section 1 and the tube tail end 12 due to its own elastic force, thereby improving the sealing effect. The setting of the inclined groove 51 can reduce the shear stress that the rubber ring 5 bears when it is squeezed, and reduce the occurrence of a decrease in the sealing effect caused by damage to the rubber ring 5. Through the above structure, the gap between the tube tail end 12 and the tube front section 1 can be further reduced, thereby further improving the sealing effect of the water supply pipe connection.

[0031] like Figures 1 to 3 As shown, a limiting groove 6 is provided on the outer side wall of the tube tail end 12; the limiting groove 6 and the shape of the protrusion 16 are correspondingly arranged;

[0032] The multiple protrusions 16 are sunk into the limiting groove 6 and will not easily detach from the protrusions 16 under the action of the first screw sleeve 15. Therefore, when the second screw sleeve 21 rotates to drive the multiple connecting plates 14 to move, the slippage between the tube tail end 12 and the protrusions 16 can be reduced, so that the tube tail end 12 can stably move toward the direction of the tube front section 1 as the second screw sleeve 21 rotates, thereby improving the bonding tightness between the tube tail end 12 and the tube front section 1, and further improving the connection sealing between the tube tail end 12 and the tube front section 1.

[0033] like Figures 2 to 4 As shown, a rubber pad 7 is fixed to the side wall of the front section 1 of the tube; the rubber pad 7 is arranged around the front section 1 of the tube;

[0034] The rubber pad 7 is squeezed by the tube tail end 12 and the tube front section 1, so that the rubber pad 7 is deformed by force and the gap between the tube tail end 12 and the tube front section 1 is reduced, thereby further improving the connection sealing between the tube tail end 12 and the tube front section 1.

[0035] The working principle and use process of this utility model:

[0036] The front section 1 and the tail end 12 of a pair of water supply pipes are connected respectively, so that the end of the tail end 12 is inserted between the end of the front section 1 and the multiple connecting plates 14. After the connection is completed, the first screw sleeve 15 is rotated to move the first screw sleeve 15 to the position where the multiple connecting plates 14 are provided with protrusions 16. The first screw sleeve 15 squeezes the multiple connecting plates 14, so that the multiple protrusions 16 are tightly fitted with the middle of the tail end 12 of the pipe and increase the friction, so that the tail end 12 will not be easily separated from the front section 1. After the multiple protrusions 16 squeeze the middle of the tail end 12 of the pipe, the second screw sleeve 21 can be rotated to drive the multiple connecting plates 14 to move. The plate 14 moves in the direction away from the tube tail end 12, and the tube tail end 12 is pulled by the multiple connecting plates 14, so that the tube tail end 12 moves in the direction of the tube front section 1, so that the tube tail end 12 and the tube front section 1 can fit more closely. When the second screw sleeve 21 needs to be rotated, the hand needs to contact the surface of the second screw sleeve 21. The multiple card grooves 3 are provided to increase the friction between the hand and the second screw sleeve 21. After the rotation of the second screw sleeve 21 is completed to make the tube tail end 12 and the tube front section 1 tightly connected, the slider 4 is slid to make the bottom of the slider 4 engage with the multiple card grooves 3. When the slider 4 is slid to the finger After a certain distance, the insertion rod 41 will enter the slot 43 under the pull of the elastic rope 42, so that the slider 4 will not slide easily. At the same time, due to the meshing relationship between the slider 4 and the card slot 3, the second screw sleeve 21 will not be easily rotated due to the vibration of the pipeline. When the pipe tail end 12 is inserted between the pipe front section 1 and the connecting plate 14, the rubber ring 5 is squeezed and deformed by the pipe tail end 12. After the pipe tail end 12 is connected to the pipe front section 1, the rubber ring 5 will block the gap between the pipe front section 1 and the pipe tail end 12 due to its own elastic force, thereby improving the sealing effect. The setting of the inclined groove 51 can reduce the pressure on the rubber ring 5 when it is squeezed. The shear stress is reduced, and the sealing effect is reduced due to damage of the rubber ring 5. The multiple protrusions 16 will sink into the interior of the limiting groove 6 and will not easily detach from the interior of the protrusion 16 under the action of the first screw sleeve 15. Therefore, when the second screw sleeve 21 rotates to drive the multiple connecting plates 14 to move, the slippage between the tube tail end 12 and the protrusion 16 can be reduced, so that the tube tail end 12 can move stably toward the direction of the tube front section 1 as the second screw sleeve 21 rotates. The rubber pad 7 is squeezed by the tube tail end 12 and the tube front section 1, so that the rubber pad 7 is deformed by force and the gap between the tube tail end 12 and the tube front section 1 is reduced.
