Description

Technical Field

[0001] The utility model relates to the technical field of water pump connectors, and particularly relates to a quick interchangeable water pump connector. Background Art

[0002] The water pump connector is an indispensable part of the water pump system. It is mainly used to connect the inlet and outlet pipes of the water pump to achieve smooth fluid transmission and has various functional characteristics. In addition, the water pump connector plays an important role in the water pump system, and its selection, installation, and maintenance all require high attention.

[0003] A Chinese patent with the publication number CN213655113U discloses a connection joint of a water pump, which includes a housing, a pump body installed in the housing, and a connection joint installed at the water inlet end of the pump body. A bracket is fixedly installed in the housing, the pump body is fixedly installed on the bracket, the connection joint includes a conversion joint threadedly connected to the water inlet end of the pump body and a water inlet joint sleeved outside the conversion joint. The water inlet joint is fixedly installed on the bracket, and a temperature probe is installed at the upper end of the water inlet joint. In the utility model, the conversion joint is directly installed at the water inlet end of the water pump, and the water inlet joint is sleeved on the conversion joint, so that the temperature probe installed on the water inlet joint is vertically upward, and at the same time, the sealing performance at the connection joint is ensured.

[0004] As described above, this patent provides a connection joint of a water pump, which can sleeve the water inlet joint on the conversion joint, make the temperature probe installed on the water inlet joint vertically upward, and ensure the sealing performance at the connection joint. However, according to the working conditions of the water pump, pipes with different lengths and apertures may need to be used, which inevitably requires replacing the pipes. When the water pump is in a narrow space, it is difficult to operate, and even the water pump needs to be taken out of the narrow space. After the replacement is completed, the water pump needs to be put back into the narrow space again. The operation is relatively cumbersome, and the efficiency of the replacement work remains to be improved. Summary of the Utility Model

[0005] The utility model provides a quick interchangeable water pump connector to solve the problems raised in the background art.

[0006] To solve the above problems, the present utility model provides a quick interchange joint for a water pump, which includes an inner connecting pipe, an outer connecting pipe, and a quick connection component. The quick connection component includes an inner connecting clamp and an outer connecting clamp. A L-shaped clamping block is fixedly connected to the surface of the inner connecting clamp. An L-shaped clamping groove adapted to the L-shaped clamping block is formed on the surface of the outer connecting clamp. A square cavity is formed on one side inside the L-shaped clamping block. A driving clamping cylinder is fixedly connected to the bottom of the inner wall of the square cavity. A supporting clamping rod is fixedly connected to the bottom of the inner wall of the driving clamping cylinder. A telescopic sleeve is slidably connected to the surface of the supporting clamping rod. A limiting clamping ball is fixedly connected to the top end of the telescopic sleeve. A placing chute is formed at the top of the L-shaped clamping block. An auxiliary clamping ring is fixedly connected to the bottom end of the telescopic sleeve. A limiting sliding ring is slidably connected to the surface of the supporting clamping rod and located at the bottom of the auxiliary clamping ring. A compression spring is sleeved on the surface of the supporting clamping rod. Two ends of the compression spring are respectively fixedly connected to the bottom of the limiting sliding ring and the bottom of the inner wall of the driving clamping cylinder. A hemispherical clamping groove adapted to the limiting clamping ball is formed on one side at the top of the inner wall of the L-shaped clamping groove.

[0007] Preferably: One ends of the telescopic sleeve and the supporting clamping rod penetrate through the driving clamping cylinder and the L-shaped clamping block and extend into the placing chute. One end of the telescopic sleeve located inside the placing chute is fixedly connected to the surface of the limiting clamping ball.

[0008] Preferably: The number of the L-shaped clamping blocks and the L-shaped clamping grooves are both set to four, and the four L-shaped clamping blocks and L-shaped clamping grooves are respectively arranged circumferentially and uniformly on the surfaces of the inner connecting clamp and the outer connecting clamp. The number of the driving clamping cylinders and the hemispherical clamping grooves are both set to be multiple, and the multiple driving clamping cylinders and hemispherical clamping grooves are arranged equidistantly and uniformly on one side at the top of the L-shaped clamping block.

[0009] Preferably: The length of the L-shaped clamping groove is greater than the length of the L-shaped clamping block. A sealing piston block is clamped on one side of the L-shaped clamping block inside the L-shaped clamping groove. A sealing shield is fixedly connected to the surface of the sealing piston block.

[0010] Preferably: One side of the inner connecting clamp is fixedly connected to one end of the inner connecting pipe. One side of the outer connecting clamp is fixedly connected to one end of the outer connecting pipe. Sealing clamping grooves are formed on the surfaces of the inner connecting clamp and the outer connecting clamp. A sealing clamping ring is clamped inside the sealing clamping groove.

[0011] The beneficial effects of adopting the above technical solutions are:

[0012] By setting up a quick-connect component, during operation, the L-shaped clamping block is fixed on the surface of the internal clamping ring, and the L-shaped clamping groove is formed on the surface of the external clamping ring. When connection is required, the L-shaped clamping block is snapped into the L-shaped clamping groove. Then, the internal clamping ring is slightly rotated to drive the L-shaped clamping block to rotate. At this time, the top of the inner wall of the L-shaped clamping groove presses the limit clamping ball, and then the limit clamping ball drives the telescopic sleeve to slide downward, thereby starting to compress the compression spring. When the L-shaped clamping block rotates and the limit clamping ball rotates into the hemispherical clamping groove, the compressed spring generates elastic force due to compression, and then pushes the limit sliding ring upward. The upward movement of the limit sliding ring pushes the auxiliary clamping ring upward, so that the telescopic sleeve at the top of the auxiliary clamping ring slides upward inside the transmission barrel, thereby lifting the limit clamping ball upward to snap into the hemispherical clamping groove. At this time, the quick installation is completed. During disassembly, due to the limiting effect of this compression spring, the limit clamping ball can drive the telescopic sleeve to slide inside the transmission barrel under force. When the limit clamping ball slides out of the hemispherical clamping groove, the limit clamping ball loses its limit and can be quickly disassembled. Moreover, the horizontal plane of this connection is perpendicular to the horizontal plane of the pipeline water flow, which can prevent the water flow from flushing open the interface, further improving the practicality of the connection. Overall, it is convenient for disassembly and assembly, improving the efficiency of replacement work. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As Figure 1 - Figure 7As shown in the figure, in this embodiment, a quick interchangeable joint for a water pump includes an inner connecting pipe 1, an outer connecting pipe 2, and a quick connection component. The quick connection component includes an inner connecting collar 3 and an outer connecting collar 4. A L-shaped clamping block 5 is fixedly connected to the surface of the inner connecting collar 3. An L-shaped clamping groove 6 adapted to the L-shaped clamping block 5 is formed on the surface of the outer connecting collar 4. A square cavity 7 is formed on one side inside the L-shaped clamping block 5. A driving clamping cylinder 8 is fixedly connected to the bottom of the inner wall of the square cavity 7. A supporting clamping rod 9 is fixedly connected to the bottom of the inner wall of the driving clamping cylinder 8. A telescopic sleeve 10 is slidably connected to the surface of the supporting clamping rod 9. A limiting clamping ball 11 is fixedly connected to the top end of the telescopic sleeve 10. A placement chute 12 is formed at the top of the L-shaped clamping block 5. An auxiliary clamping ring 13 is fixedly connected to the bottom end of the telescopic sleeve 10. A limiting sliding ring 14 is slidably connected to the surface of the supporting clamping rod 9 and located at the bottom of the auxiliary clamping ring 13. A compression spring 15 is sleeved on the surface of the supporting clamping rod 9. The two ends of the compression spring 15 are respectively fixedly connected to the bottom of the limiting sliding ring 14 and the bottom of the inner wall of the driving clamping cylinder 8. A hemispherical clamping groove 16 adapted to the limiting clamping ball 11 is formed on one side of the top of the inner wall of the L-shaped clamping groove 6.

[0025] Through the above technical solution, the square cavity 7 is formed on one side inside the L-shaped clamping block 5 for fixedly installing the driving clamping cylinder 8. The telescopic sleeve 10 slides inside the driving clamping cylinder 8, and the supporting clamping rod 9 is fixed. The limiting sliding ring 14 is sleeved on the surface of the supporting clamping rod 9. The bottom of the limiting sliding ring 14 is fixedly connected with the compression spring 15, and the bottom end of the compression spring 15 is fixedly connected with the bottom of the inner wall of the driving clamping cylinder 8. During operation, the L-shaped clamping block 5 is fixed on the surface of the inner connecting collar 3, and the L-shaped clamping groove 6 is formed on the surface of the outer connecting collar 4. When connection is required, the L-shaped clamping block 5 is inserted into the L-shaped clamping groove 6, and then the inner connecting collar 3 is slightly rotated to drive the L-shaped clamping block 5 to rotate. At this time, the top of the inner wall of the L-shaped clamping groove 6 presses the limiting clamping ball 11, and then the limiting clamping ball 11 drives the telescopic sleeve 10 to slide downward, thereby starting to compress the compression spring 15. When the limiting clamping ball 11 is rotated into the hemispherical clamping groove 16 after the L-shaped clamping block 5 rotates, the compression spring generates elastic force due to compression, thereby pushing the limiting sliding ring 14 to move upward. The upward movement of the limiting sliding ring 14 pushes the auxiliary clamping ring 13 to move upward, so that the telescopic sleeve 10 at the top of the auxiliary clamping ring 13 slides upward inside the driving clamping cylinder 8, thereby lifting the limiting clamping ball 11 upward to be clamped into the hemispherical clamping groove 16. At this time, the quick installation is completed. During disassembly, due to the limiting effect of this compression spring 15, the limiting clamping ball 11 can drive the telescopic sleeve 10 to slide inside the driving clamping cylinder 8 by force. After the limiting clamping ball 11 slides out of the hemispherical clamping groove 16, the limiting clamping ball 11 loses its limit and can be quickly disassembled. Moreover, the connection horizontal plane is perpendicular to the horizontal plane of the pipeline water flow, which can prevent the water flow from flushing open the interface, further improving the practicality of the connection. The overall disassembly and assembly are convenient, improving the efficiency of the replacement work.

[0026] As Figure 3 , Figure 5 and Figure 6 shown, one end of the telescopic sleeve 10 and the support rod 9 penetrate through the transmission cylinder 8 and the L-shaped clamping block 5 and extend into the placement chute 12; one end of the telescopic sleeve 10 located inside the placement chute 12 is fixedly connected to the surface of the limit clamping ball 11; the number of the L-shaped clamping blocks 5 and the L-shaped clamping grooves 6 is set to four, and the four L-shaped clamping blocks 5 and the L-shaped clamping grooves 6 are respectively arranged circumferentially and uniformly on the surfaces of the inner connecting ring 3 and the outer connecting ring 4; the number of the transmission cylinders 8 and the hemispherical grooves 16 is set to a plurality, and the plurality of transmission cylinders 8 and the hemispherical grooves 16 are arranged equidistantly and uniformly on one side of the top of the L-shaped clamping block 5.

[0027] Through the above technical solution, the telescopic sleeve 10 and the support rod 9 penetrate to the inner wall of the placement chute 12. The placement chute 12 is opened on one side of the top of the L-shaped clamping block 5 and is used for the up and down sliding of the limit clamping ball 11. At the same time, four L-shaped clamping blocks 5 and L-shaped clamping grooves 6 are provided and are respectively arranged circumferentially and uniformly on the surfaces of the inner connecting ring 3 and the outer connecting ring 4, and the four L-shaped clamping blocks 5 and the L-shaped clamping grooves 6 correspond to each other one by one, thereby improving the connection stability. In addition, a plurality of transmission cylinders 8 and hemispherical grooves 16 are arranged on the surface of one L-shaped clamping block 5. The plurality of transmission cylinders 8 cooperate with the limit clamping ball 11 and correspond to the plurality of hemispherical grooves 16, further improving the connection stability effect.

[0028] As Figure 2 - Figure 4 shown, the length of the L-shaped clamping groove 6 is greater than the length of the L-shaped clamping block 5; a sealing piston block 17 is clamped inside the L-shaped clamping groove 6 and on one side of the L-shaped clamping block 5; a sealing cover 18 is fixedly connected to the surface of the sealing piston block 17; one side of the inner connecting ring 3 is fixedly connected to one end of the inner connecting pipe 1; one side of the outer connecting ring 4 is fixedly connected to one end of the outer connecting pipe 2; sealing grooves 19 are opened on the surfaces of the inner connecting ring 3 and the outer connecting ring 4; a sealing ring 20 is clamped inside the sealing groove 19.

[0029] Through the above technical solution, the length of the L-shaped clamping groove 6 is set to be greater than the length of the L-shaped clamping block 5, so that the L-shaped clamping block 5 can slide inside the L-shaped clamping groove 6. When the installation is completed, the sealing piston block 17 can be clamped into the remaining gap inside the L-shaped clamping groove 6, and the sealing cover 18 is fixed on the surface of the sealing piston block 17 to seal the sealed part of this gap. In addition, sealing grooves are opened on the surfaces of the inner connecting ring 3 and the outer connecting ring 4 for clamping and installing the sealing ring 20. The sealing ring 20 seals the connection part of the inner connecting ring 3 and the outer connecting ring 4, further improving the sealing effect.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the present utility model, rather than limiting the technical solutions described in the present utility model; therefore, although this specification has described the present utility model in detail with reference to the above respective embodiments, however, those of ordinary skill in the art should understand that the present utility model can still be modified or equivalently replaced, and all technical solutions and their improvements that do not depart from the spirit and scope of the present utility model should be covered within the scope of the claims of the present utility model; the technologies not described in detail in the present utility model are implemented with the prior art.
