[0034] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Reference Figures 1 to 4 As shown, this utility model provides a water pump, including a pump casing 10, a pump body assembly 20, a first connecting member 30, a second connecting member 50, a first fastener 70, and a second fastener 80, wherein:

[0036] The pump body assembly 20 is connected to the pump casing 10. The pump body assembly 20 is provided with an inlet 21 and an outlet 22. The medium can enter the water pump through the inlet 21 and be discharged through the outlet 22.

[0037] The first connector 30 is connected to the water inlet 21. A first seal 40 is provided at the connection between the first connector 30 and the water inlet 21. When the first connector 30 with the first seal 40 is inserted into the water inlet 21, the first connector 30 and the water inlet 21 can be sealed by the first seal 40, which effectively prevents media leakage.

[0038] Similarly, the second connector 50 is connected to the outlet 22. A second seal 60 is provided at the connection between the second connector 50 and the outlet 22. When the second connector 50 with the second seal 60 is inserted into the outlet 22, the second connector 50 and the outlet 22 can be sealed by the second seal 60, which can also effectively prevent media leakage.

[0039] The first seal 40 and the second seal 60 can form independent sealing areas at the connection between the first connector 30 and the inlet 21 and at the connection between the second connector 50 and the outlet 22, respectively. Even if the seal on one side ages, the other side can still continue to work, thereby ensuring the stability of the water pump operation.

[0040] The first fastener 70 is used to securely connect the first connector 30 to the inlet 21, so that the first connector 30 is stably fixed to the inlet 21. The second fastener 80 is used to securely connect the second connector 50 to the outlet 22, so that the second connector 50 is stably fixed to the outlet 22. Thus, under the combined action of the first seal 40, the second seal 60, the first fastener 70 and the second fastener 80, the first connector 30 and the second connector 50 form a double seal lock with the inlet 21 and the outlet 22 respectively, effectively preventing loosening and leakage, thereby improving the stability of the water pump operation.

[0041] The sealing element can be selected according to the actual situation. Therefore, the water pump of this utility model can be connected to both plastic pipes and steel pipes, and can ensure the sealing performance between the water pump and the pipe, effectively preventing media leakage, thereby improving the versatility and adaptability of the water pump.

[0042] In order to improve the sealing performance of the first seal 40 and the second seal 60, in the embodiments provided in this application, the first seal 40 includes at least two, and the at least two first seals 40 are sequentially disposed on the first connector 30, and the second seal 60 includes at least two, and the at least two second seals 60 are sequentially disposed on the second connector 50.

[0043] At least two first seals 40 are provided at the connection between the first connector 30 and the inlet 21. Even if one of the first seals 40 experiences local wear or instantaneous failure, the other first seal 40 can reliably cut off the medium, effectively reducing the risk of sudden leakage at the inlet 21.

[0044] Similarly, at least two second seals 60 are provided at the connection between the second connector 50 and the outlet 22. Even if one of the second seals 60 experiences local wear or momentary failure, the other second seal 60 can reliably cut off the medium, effectively reducing the risk of sudden leakage at the outlet 22.

[0045] In other embodiments, the number of the first seal 40 and the second seal 60 can be selected according to actual needs, and is not limited here.

[0046] In one feasible embodiment, the first sealing element 40 includes a first sealing ring 41 disposed on the first connecting element 30, and the second sealing element 60 includes a second sealing ring 61 disposed on the second connecting element 50. Specifically, the first sealing ring 41 and the second sealing ring 61 can be O-rings, which are respectively fitted onto the first connecting element 30 and the second connecting element 50, and then the first connecting element 30 and the second connecting element 50 are respectively inserted into the water inlet 21 and the water outlet 22 to seal the water inlet 21 and the water outlet 22 respectively.

[0047] In other embodiments, the shape and size of the first sealing ring 41 and the second sealing ring 61 can be set according to the actual situation, and are not limited here.

[0048] Reference Figure 2 and Figure 4 As shown in the embodiment provided in this application, the first fastener 70 includes a first bolt 71, the first connector 30 is provided with a first threaded hole 31, and the outer periphery of the water inlet 21 is provided with a second threaded hole 23. The first threaded hole 31 and the second threaded hole 23 can be threadedly engaged with the first bolt 71, and the first bolt 71 is sequentially inserted into the first threaded hole 31 and the second threaded hole 23. The first bolt 71 is simultaneously screwed into both the first threaded hole 31 and the second threaded hole 23, which not only achieves axial fastening between the first connector 30 and the water inlet 21, but also restricts the radial displacement of the first connector 30, ensuring the stability of the connection between the first connector 30 and the water inlet 21. Even with long-term vibration of the water pump, it is not easy to loosen, thereby effectively reducing the risk of leakage.

[0049] Similarly, the second fastener 80 includes a second bolt 81, the second connector 50 has a third threaded hole 51, and the outer periphery of the outlet 22 has a fourth threaded hole 24. The third threaded hole 51 and the fourth threaded hole 24 can be threaded into the second bolt 81, and the second bolt 81 is sequentially inserted into the third threaded hole 51 and the fourth threaded hole 24. The second bolt 81 engages with both the third threaded hole 51 and the fourth threaded hole 24, which not only achieves axial fastening between the second connector 50 and the outlet 22, but also restricts the radial displacement of the second connector 50, ensuring the stability of the connection between the second connector 50 and the outlet 22 and further reducing the risk of leakage.

[0050] The first connector 30 and the second connector 50 are fastened to the inlet 21 and the outlet 22 respectively by means of bolts and threaded holes. On the one hand, the bolts and threaded holes can achieve axial fastening and radial positioning at the same time, making the structure of the water pump more compact. The threaded connection is self-locking and vibration-resistant, which can effectively prevent loosening. On the other hand, it allows the first connector 30 to be detachably connected to the inlet 21 and the second connector 50 to the outlet 22, which is convenient for disassembly and assembly and easy for maintenance.

[0051] In other embodiments, the first fastener 70 and the second fastener 80 may adopt other structures or components, which are not limited here.

[0052] When the water pump needs maintenance, the liquid inside the pump must be drained quickly, referring to... Figure 1 and Figure 3 As shown, the pump assembly 20 is also provided with a drain section 25, which is used to quickly discharge liquid.

[0053] Specifically, refer to Figure 2 and Figure 4 As shown, the drainage section 25 includes a drainage port 251, which is disposed opposite to the inlet 21. The drainage port 251 is located below the inlet 21, forming an opposing flow channel with one inlet and one outlet. During maintenance, only the drainage port 251 needs to be opened to instantly drain the liquid using the liquid level difference and residual pressure, without disassembling the pipeline or tilting the pump body, thus achieving rapid drainage.

[0054] To facilitate fixing the water pump position as needed, refer to Figures 1 to 4 As shown, the pump body assembly 20 is provided with a first positioning part 26 for fixing the water pump. The pump body assembly 20 is also provided with a second positioning part 27, which is located on the side of the pump body assembly 20 opposite to the first positioning part 26. The first positioning part 26 and the second positioning part 27 can also be provided in other mutually offset positions on the pump body assembly 20 to facilitate fixing the water pump from multiple angles. The first positioning part 26 and the second positioning part 27 can be set according to the fixing requirements of the water pump, and are not limited here.
