Description
Technical Field
[0001] This utility model relates to the field of water pump technology, specifically a water pump that facilitates tight connection with water pipes. Background Technology
[0002] In industrial production, agricultural irrigation, municipal water supply, and building water supply and drainage, water pumps, as core equipment for liquid transportation, need to be connected to water sources, water-using equipment, or other pipeline systems through pipes. The tightness and convenience of the connection between the pump and the water pipe directly affect the system's operating efficiency, safety, and maintenance costs. Traditional connection methods rely solely on bolt fixing. When the pump is running, vibration can easily cause the bolts to loosen. Furthermore, when existing pumps and pipes are connected, impurities or solid particles inside can easily cause blockages and accumulate inside the pipe walls, making them difficult to clean. To solve these problems, a water pump that can easily and tightly connect to water pipes is needed.
[0003] In existing water pumps, the connection to the external water pipe is mainly fixed by bolts. The vibration generated during the operation of the water pump can cause the bolts to loosen, thereby affecting the sealing of the connection. In addition, the liquid medium being transported may contain impurities and other solid particles, which can easily cause blockage in the pipe or accumulate on the pipe wall and be difficult to clean. Therefore, there is an urgent need for a water pump that can easily and tightly connect to the water pipe. Utility Model Content
[0004] Based on this, the purpose of this utility model is to provide a water pump that can be conveniently and tightly connected to water pipes, so as to solve the problem that when existing water pumps are used, the connection with external water pipes is mainly fixed by bolts. The vibration generated by the water pump during operation can cause the bolts to loosen, thereby affecting the sealing of the connection. In addition, the transported liquid medium may contain impurities and other solid particles, which can easily cause blockage in the pipe or accumulate on the pipe wall and are difficult to clean.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water pump that facilitates tight connection with water pipes, comprising a pump body, a water guide pipe installed on the outer wall of the pump body, a positioning sleeve installed on the outer wall of the water guide pipe, a clamping plate installed on the inner wall of the positioning sleeve, a limit spring installed on the inner wall of the clamping plate, a clamping rod installed on the outer wall of the limit spring, a filter screen installed on the inner wall of the clamping plate, a positioning groove formed on the outer wall of the water guide pipe, an outer connecting pipe installed on the outer wall of the water guide pipe, a positioning slider installed on the inner wall of the outer connecting pipe, a sealing groove formed on the side wall of the outer connecting pipe, a sealing ring installed on the inner wall of the sealing groove, a fixed shaft penetrating the interior of the outer connecting pipe, and a fixing sleeve installed on the outer wall of the fixed shaft.
[0006] Preferably, the bottom of the positioning sleeve is an open design, and the card plate is inserted into the positioning sleeve.
[0007] Preferably, the locking rod forms a telescopic structure with the locking plate through a limiting spring, and the locking rod is engaged with the positioning sleeve.
[0008] Preferably, the clamping rod is symmetrically arranged with the central axis of the clamping plate as the center, and the outer diameter of the filter screen matches the inner diameter of the water guide pipe.
[0009] Preferably, the outer pipe is sleeved with the water guide pipe, and the positioning slider is engaged with the positioning groove.
[0010] Preferably, the sealing ring fits tightly into the sealing groove, and the fixed shaft passes through the inner wall of the outer pipe and the water guide pipe and is threadedly connected to the fixed sleeve.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. This utility model, through the design of a pump body, water guide pipe, positioning sleeve, clamping plate, limiting spring, clamping rod, and filter screen, allows for easy assembly and disassembly. The clamping rod is pressed inwards, and the clamping plate is inserted into the positioning sleeve. The clamping rod is then pushed outwards by the spring force of the limiting spring, engaging with the positioning sleeve. The clamping rod extends a certain length from the side wall of the positioning sleeve, ensuring high connection stability even if the pump body vibrates during operation, causing the limiting spring to extend or retract. The filter screen matches the inner diameter of the water guide pipe, effectively filtering and intercepting the internal liquid medium, preventing solid particles or impurities from entering the pump body and causing abnormal wear. Furthermore, the bottom of the positioning sleeve is open, allowing intercepted solid particles to be discharged along with the filter screen, facilitating cleaning and preventing blockages.
[0013] 2. This utility model uses a positioning groove, an outer pipe, a positioning slider, a sealing groove, a sealing ring, a fixed shaft, and a fixed sleeve to connect the outer pipe to the water guide pipe. The positioning slider is pushed along the positioning groove to the bottom, and then the outer pipe is rotated 45 degrees clockwise to engage the positioning slider with the positioning groove. The fixed shaft passes through the interior of the outer pipe and the water guide pipe and is threadedly fixed to the fixed sleeve. Even if the pump body vibrates during operation, the fixed shaft can be tightened due to the engaging and limiting effect of the positioning slider and the positioning groove, preventing the fixed shaft from loosening from the fixed sleeve. This facilitates connection while ensuring a tight fit, preventing loosening and falling off, and improving stability. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.
[0020] The embodiments of this utility model will be described below based on its overall structure.
[0021] Please see Figures 1-4 A water pump for convenient and tight connection with water pipes includes a pump body 1, a water guide pipe 2 installed on the outer wall of the pump body 1, a positioning sleeve 3 installed on the outer wall of the water guide pipe 2, a retaining plate 4 installed on the inner wall of the positioning sleeve 3, a limit spring 5 installed on the inner wall of the retaining plate 4, a retaining rod 6 installed on the outer wall of the limit spring 5, and a filter screen 7 installed on the inner wall of the retaining plate 4. The bottom of the positioning sleeve 3 is open, and the retaining plate 4 is inserted into the positioning sleeve 3. The retaining rod 6 forms a telescopic structure with the retaining spring 5 and the retaining plate 4, and the retaining rod 6 is engaged with the positioning sleeve 3. The retaining rod 6 is symmetrically arranged around the central axis of the retaining plate 4. The outer diameter of the filter screen 7 matches the inner diameter of the water guide pipe 2. The system consists of a water guide pipe 2, a positioning sleeve 3, a clamping plate 4, a limiting spring 5, a clamping rod 6, and a filter screen 7. Pressing the clamping rod 6 inwards and then inserting the clamping plate 4 into the positioning sleeve 3 causes the clamping rod 6 to push outwards through the elastic force of the limiting spring 5, thus engaging with the positioning sleeve 3 for easy assembly and disassembly. The clamping rod 6 extends a certain length from the side wall of the positioning sleeve 3, ensuring that even if the pump body 1 vibrates during operation, causing the limiting spring 5 to extend or retract, the clamping rod 6 will not detach from the positioning sleeve 3, resulting in high connection stability. The filter screen 7 matches the inner diameter of the water guide pipe 2, filtering and intercepting the internal liquid medium to prevent solid particles or impurities from entering the pump body 1 and causing abnormal wear. Furthermore, the bottom of the positioning sleeve 3 has an open design, allowing intercepted solid impurities to be discharged along with the filter screen 7, facilitating cleaning and preventing blockages.
[0022] Please see Figures 1-4A water pump for convenient and tight connection of water pipes is provided. A positioning groove 8 is formed on the outer wall of the water guide pipe 2. An outer connecting pipe 9 is installed on the outer wall of the water guide pipe 2. A positioning slider 10 is installed on the inner wall of the outer connecting pipe 9. A sealing groove 11 is formed on the side wall of the outer connecting pipe 9. A sealing ring 12 is installed on the inner wall of the sealing groove 11. A fixing shaft 13 passes through the interior of the outer connecting pipe 9. A fixing sleeve 14 is installed on the outer wall of the fixing shaft 13. The outer connecting pipe 9 is sleeved with the water guide pipe 2. The positioning slider 10 engages with the positioning groove 8. The sealing ring 12 fits tightly with the sealing groove 11. The fixing shaft 13 passes through the inner walls of the outer connecting pipe 9 and the water guide pipe 2 and is threadedly connected to the fixing sleeve 14. The pump utilizes the positioning groove 8, the outer connecting pipe 9, and the positioning slider... 10. Sealing groove 11, sealing ring 12, fixed shaft 13, and fixed sleeve 14 are used to connect the outer pipe 9 to the water guide pipe 2, and the positioning slider 10 is pushed along the positioning groove 8 to the bottom. Then, the outer pipe 9 is rotated 45 degrees clockwise to make the positioning slider 10 engage with the positioning groove 8. Then, the fixed shaft 13 passes through the interior of the outer pipe 9 and the water guide pipe 2 and is threaded to the fixed sleeve 14. Even if the pump body 1 vibrates during operation, the fixed shaft 13 can be tightened due to the engagement and limiting effect of the positioning slider 10 and the positioning groove 8, which prevents the fixed shaft 13 from loosening from the fixed sleeve 14. This facilitates connection and ensures a tight fit, preventing it from loosening or falling off, thus improving stability.
[0023] Working principle: In use, first press the locking rod 6 inward, then insert the locking plate 4 into the positioning sleeve 3. At this time, the locking rod 6 is pushed outward by the elastic force of the limiting spring 5, so that the locking rod 6 and the positioning sleeve 3 are engaged and connected, which is convenient for disassembly and assembly. At the same time, the locking rod 6 extends a certain length from the side wall of the positioning sleeve 3. Even if the pump body 1 drives the water guide pipe 2 to vibrate when it is working, causing the limiting spring 5 to have a certain extension and contraction stroke, the locking rod 6 will not fall off the positioning sleeve 3, so the connection stability is high. The filter screen 7 matches the inner diameter of the water guide pipe 2, which can filter and intercept the internal liquid medium to prevent solid particles or impurities from entering the pump body 1 and causing abnormal wear. Meanwhile, the bottom of the positioning sleeve 3 is designed with an open type. The intercepted solid impurity particles will be discharged along with the filter screen 7, which is convenient for cleaning and avoids blockage. Then, the outer pipe 9 is connected to the water guide pipe 2, and the positioning slider 10 is pushed along the positioning groove 8 to the bottom. Then, the outer pipe 9 is rotated 45 degrees clockwise to make the positioning slider 10 engage with the positioning groove 8. Then, the fixed shaft 13 passes through the interior of the outer pipe 9 and the water guide pipe 2 and is threaded to the fixed sleeve 14. Even if the pump body 1 vibrates during operation, the fixed shaft 13 can be tightened due to the engagement and limiting effect of the positioning slider 10 and the positioning groove 8, which prevents the fixed shaft 13 from loosening from the fixed sleeve 14. This facilitates connection and ensures a tight fit, preventing it from loosening and falling off, thus improving stability. Finally, the pump body 1 is started to work, which completes the use of the device.
