[0003] The existing circulating water pump includes a pump casing, a motor and an impeller. The impeller is rotatably connected to the inside of the pump casing, the motor is fixedly connected to the side wall of the pump casing, the output shaft of the motor passes through the side wall of the pump casing and is fixedly connected to the middle part of the impeller, a water inlet and a water outlet are arranged on the pump casing, and water pipes are arranged at the water inlet and the water outlet. The staff connects the water pipe and the pump casing with the help of a clamp. When using the water pump, extend the end of the water pipe connected to the water inlet away from the pump casing to the water source, and then fill the water pipe connected to the water inlet with water, start the motor, the motor drives the impeller to rotate, water enters the pump casing, the impeller drives the water to rotate, and the water flows out of the pump casing from the water outlet through centrifugal force. After the water pump is used, the staff manually loosens the clamp and removes the water pipe for collection.

[0004] With regard to the above-mentioned related technologies, when the water pump is connected to or separated from the water pipe, the staff is required to manually tighten or loosen the clamp with the help of tools, which results in the defect of inconvenience in connecting the water pipe and the water pump. Utility Model Content

[0005] In order to improve the convenience of connecting the water pipe and the water pump, the present application provides a circulating water pump.

[0006] The present application provides a circulating water pump adopting the following technical solution:

[0007] A circulating water pump comprises a pump body, wherein a water inlet and a water outlet are arranged on the side wall of the pump body, a connecting pipe is connected to the water inlet and the water outlet of the pump body, a water pipe is arranged on one end of the connecting pipe away from the pump body, a plug is fixedly connected to one end of the water pipe close to the connecting pipe, the inner diameter of the plug is smaller than the inner diameter of the connecting pipe, a sleeve is arranged outside the plug, the end of the sleeve away from the water pipe is open, a clamp is fixedly connected to the inner wall of the sleeve, a guide groove is arranged on the outer wall of the connecting pipe along its length direction, the guide groove runs through the side of the connecting pipe away from the pump body, a clamp is arranged on the side wall of the connecting pipe close to one end of the pump body in the guide groove, the clamp and the slot are snap-fitted, and the sleeve and the connecting pipe are plug-fitted.

[0008] By adopting the above technical solution, when the pump body is connected to the water pipe, one end of the water pipe connecting plug is moved toward the connecting pipe, and the plug drives the casing to move, so that the connecting pipe gradually enters the casing, and the casing drives the block to move. The block initially moves in the guide groove. When the block moves to the guide groove close to one end of the pump body, the casing is rotated, and the casing drives the block to move, so that the block is engaged in the slot, thereby realizing the engagement of the water pipe and the connecting pipe. There is no need to use a clamp to connect the water pipe and the connecting pipe, thereby improving the convenience of connecting the water pipe and the water pump.

[0009] Optionally, a sliding groove is provided on a side of the guide groove close to the pump body of the connecting pipe, and the connecting pipe is slidably connected to a stopper in the sliding groove.

[0010] By adopting the above technical solution, when the card block moves in the guide groove toward the pump body, the card block first abuts against the stop block and pushes the stop block to move toward the slide groove. After the card block moves into the card groove, the stop block moves away from the pump body. One end of the block moves out of the slide groove and blocks the card block, making it difficult for the card block to detach from the card groove, thereby improving the stability of the connection between the water pipe and the pump body.

[0011] Optionally, a first spring is fixedly provided between the stopper and a side wall of the slide groove close to the pump body.

[0012] By adopting the above technical solution, when the block moves toward the slide groove, the first spring is compressed. After the blocking block moves into the blocking groove, the first spring releases its elastic force to push the block to move, so that the block moves away from the end of the first spring into the guide groove. There is no need for the staff to manually move the block away from the pump body, thereby providing convenience for the staff.

[0013] Optionally, a sliding sleeve is provided on the outer sleeve of the connecting pipe, and the sliding sleeve is slidably connected to the connecting pipe along the length direction of the connecting pipe, and the stopper is fixedly connected to the sliding sleeve on the side away from the bottom wall of the sliding groove.

The setting of the sliding sleeve provides convenience for moving the block.

[0015] Optionally, the outer surface of the sliding sleeve is a frosted surface.

[0016] By adopting the above technical solution, when the worker moves the sliding sleeve toward the pump body, the setting of the frosted surface increases the friction between the worker's hand and the sliding sleeve, making it easier for the worker to slide the sliding sleeve.

[0017] Optionally, an annular plate is connected to the interior of the connecting pipe, the length directions of the annular plate and the connecting pipe are perpendicular, and a sealing gasket is provided on the side of the annular plate away from the pump body.

[0018] By adopting the above technical solution, after the water pipe and the connecting pipe are connected, the end of the insert pipe away from the water pipe is tightly abutted against the sealing gasket, making it difficult for water to flow to the outside through the gap between the insert pipe and the connecting pipe, thereby improving the sealing of the connection between the water pipe and the connecting pipe.

[0019] Optionally, the inner wall of the connecting tube is provided with a movable groove along its length direction, and the connecting tube is slidably connected to a slider in the movable groove, one side of the slider is fixedly connected to the annular plate, and the side of the slider away from the pump body is fixedly connected to a sliding rod, the length direction of the sliding rod is parallel to the length direction of the connecting tube, and the end of the sliding rod away from the pump body passes through the side wall of the connecting tube away from the pump body and is slidably connected to the pump body.

[0020] By adopting the above technical solution, when replacing the sealing gasket, the sliding rod is pulled in the direction away from the pump body, the sliding rod drives the slider to move, the slider drives the annular plate to move, and the annular plate drives the sealing gasket to move, so that the sealing gasket moves to the end of the connecting pipe away from the pump body. The staff takes out the damaged sealing gasket and replaces it, so that the setting of the sliding rod provides convenience for replacing the sealing gasket.

[0021] Optionally, an avoidance groove is provided on the side of the connecting pipe away from the pump body, a pull plate is provided in the avoidance groove, the pull plate and the avoidance groove are plugged and adapted, one end of the sliding rod away from the annular plate extends into the avoidance groove and is fixedly connected to the pull plate, the sliding rod and the pull plate are perpendicular, a pull ring is hinged on the side of the pull plate away from the sliding rod, a second spring is fixed between the sliding block and a side wall of the movable groove away from the pump body, and the second spring is sleeved outside the sliding rod.

[0022] By adopting the above technical solution, when replacing the sealing gasket, the pull ring is picked up in the avoidance groove and driven to move away from the pump body, the pull ring drives the pull plate to move, the pull plate drives the slide rod to move, the slide rod drives the annular plate to move, and the second spring is compressed at the same time. When the sealing gasket is removed, the pull ring is released, the second spring contracts, and pushes the slide bar to move toward the inside of the connecting pipe, and the slide bar drives the annular plate to move, so that the annular plate returns to its original position, and there is no need for the staff to manually push the pull plate toward the connecting pipe, thereby providing convenience for the staff's work.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Through the clamping of the clamping block and the clamping slot, the connection between the casing and the connecting pipe is realized, and then the connection between the water pipe and the pump body is realized. There is no need for the staff to manually connect the water pipe and the pump body through the clamp, thereby improving the convenience of connecting the water pipe and the water pump;

[0025] 2. The blocking effect of the block on the card block makes it difficult for the card block and the card slot to separate, thereby improving the stability of the connection between the water pipe and the water pump;

[0026] 3. The close contact between the insert pipe and the sealing gasket makes it difficult for water to flow to the outside through the gap between the insert pipe and the connecting pipe, thereby improving the sealing of the connection between the water pipe and the pump body.

When the pump body 1 is working, water flows into the pump body 1 from the water pipe 3 connected to the water inlet 11, and then flows out of the pump body 1 from the water outlet 12 along the water pipe 3.

[0035] refer to Figure 2 and Figure 3The pump body 1 is fixedly connected with a connecting pipe 2 at the water inlet 11 and the water outlet 12, and a plug pipe 31 is fixedly connected to one end of the water pipe 3, and the plug pipe 31 and the connecting pipe 2 are plugged and adapted. A sleeve 4 is arranged outside the plug pipe 31, and the sleeve 4 is cylindrical. The sleeve 4 and the plug pipe 31 are fixedly connected. The end of the sleeve 4 away from the water pipe 3 is open, and the connecting pipe 2 and the sleeve 4 are plugged and adapted. A plurality of guide grooves 21 are opened on the outer wall of the connecting pipe 2 along its own length direction, and the guide groove 21 runs through a side wall of the connecting pipe 2 away from the pump body 1. The plurality of guide grooves 21 are evenly distributed on the circumferential side wall of the connecting pipe 2, and a plurality of blocks 41 are fixedly connected to the inner part of the sleeve 4 away from the water pipe 3. The plurality of blocks 41 correspond to the guide grooves 21 one by one, and a slot 22 is opened on the side wall of the connecting pipe 2 near the end of the guide groove 21 of the pump body 1, and the slot 22 and the block 41 are plugged and adapted.

[0036] When the water pipe 3 and the pump body 1 are connected, first align the block 41 and the guide groove 21, move the water pipe 3 toward the pump body 1, and the water pipe 3 drives the insert pipe 31 and the casing 4 to move. The insert pipe 31 is inserted into the connecting pipe 2, and the connecting pipe 2 is between the insert pipe 31 and the casing 4. At the same time, the casing 4 drives the block 41 to move in the guide groove 21. When the block 41 and the slot 22 are aligned, rotate the casing 4, and the casing 4 drives the block 41 to move, so that the block 41 is engaged in the slot 22, thereby completing the connection between the water pipe 3 and the pump body 1.
