Description

Technical Field

[0001] This utility model relates to the field of centrifugal pump technology, and in particular to a centrifugal pump that is easy to disassemble. Background Technology

[0002] Existing easily disassembled centrifugal pump mounting devices often have drawbacks. Centrifugal pumps are typically fixed to other devices or base plates with screws. If a centrifugal pump malfunctions and requires repair, these screws must be removed to detach it. However, in complex environments such as factories or near machinery, many other mechanical parts may be distributed around the centrifugal pump. If the screws used to fix the centrifugal pump are accidentally mixed with other parts after removal, they may be difficult to find or lost, affecting the installation of the centrifugal pump. Furthermore, existing mounting bases use spring structures to dampen vibrations from the centrifugal pump. While the spring structure can reduce the vibration transmitted from the centrifugal pump to the base, it compromises the pump's fixation. During operation, vibrations can cause shaking, which can damage the bearings or seals on the inner wall of the centrifugal pump, affecting its service life. Utility Model Content

[0030] This utility model proposes a centrifugal pump that is easy to disassemble. The pump body is detachably installed on the base through two disassembly and assembly components. The disassembly and assembly are simple and convenient, avoiding the situation where the pump body is difficult to remove due to rust caused by humid environment.

[0037] In this embodiment, the centrifugal pump 10 includes a base 1, a pump body 2, two connecting seat assemblies 3, and two disassembly / assembly components 4. The two connecting seat assemblies 3 are spaced apart on both sides of the pump body 2. It should be noted that the connecting seat assemblies 3 and the pump body 2 are integrally formed to ensure the strength and stability of the structure. At the same time, each disassembly / assembly component 4 is installed on the base 1 and located on one side of the connecting seat assemblies 3 to lock or loosen the connecting seat assemblies 3 on the base 1, thereby facilitating the disassembly and assembly of the pump body 2. This allows the pump body 2 to be detachably installed on the base 1, making disassembly and assembly simple and convenient. It avoids the situation where the centrifugal pump 10 pump body 2 is difficult to remove due to rust caused by a humid environment, making the disassembly and assembly of the pump body 2 more convenient.

[0038] Meanwhile, the centrifugal pump 10 also includes a shock-absorbing assembly 5.

Each of the disassembly and assembly components 4 includes a first bracket 41, a second bracket 42, and a clamping member 43. The first bracket 41 is disposed on one side of one of the connecting seats 31, and the second bracket 42 is disposed on one side of the other connecting seat 31. One side of the clamping member 43 is rotatably connected to the second bracket 42, and the other side of the clamping member 43 is detachably connected to the first bracket 41, so that the clamping member 43 locks or releases the two connecting seats 31 on the base 1, thereby realizing the detachable installation of the pump body 2 on the base 1, which is simple and convenient to operate.

[0041] In this embodiment, each connecting seat group 3 includes two oppositely arranged connecting seats 31, and each disassembly and assembly component 4 includes a first bracket 41, a second bracket 42, and a clamping member 43. The first bracket 41 is located on one side of one of the connecting seats 31, and the second bracket 42 is located on one side of the other connecting seat 31. It should be noted that the first bracket 41 and the second bracket 42 can be installed on the base 1 by welding or other means. One side of the clamping member 43 is rotatably connected to the second bracket 42, and the other side of the clamping member 43 is detachably connected to the first bracket 41. Thus, when the clamping member 43 is rotated, the two connecting seats 31 can be locked or loosened on the base 1, thereby realizing that the pump body 2 can be detachably installed on the base 1. The disassembly and assembly are simple and convenient, avoiding the situation where the centrifugal pump 10 pump body 2 is difficult to remove due to rust caused by the humid environment, making the disassembly and assembly of the pump body 2 more convenient.

[0042] In one implementation, please refer to Figure 2 Each of the disassembly and assembly components 4 includes a first locking member 44 and a fixing rod 45. One end of the fixing rod 45 is connected to the first bracket 41, and the other end of the fixing rod 45 is provided with a boss 451. The clamping member 43 is provided with a through hole 432 on the side away from the second bracket 42. The through hole 432 passes through the fixing rod 45, and one side wall of the through hole 432 abuts against the boss 451. The first locking member 44 is threaded to the side of the fixing rod 45 that passes through the through hole 432, so as to lock the clamping member 43 to the fixing rod 45, thereby realizing that the clamping member 43 presses the connecting seat 31 onto the base 1, so as to realize that the pump body 2 is stably and firmly installed on the base 1.

[0043] In this embodiment, each disassembly and assembly component 4 includes a first locking rod and a fixing rod 45. One end of the fixing rod 45 is connected to the first bracket 41, and the other side of the fixing rod 45 is provided with a boss 451. At the same time, the clamping member 43 is provided with a through hole 432 on the side away from the second bracket 42. The through hole 432 can be inserted into the fixing rod 45, and one side wall of the through hole 432 abuts against the boss 451, so that the clamping member 43 can be stably placed on the fixing rod 45 to further press and lock the connecting seat 31 onto the base 1. The first locking member 44 is threadedly connected to the fixing rod 45. So when the clamping member 43 abuts against the fixing rod 45, by rotating the first locking member 44, the first locking member 44 locks the clamping member 43 onto the boss 451, so that the clamping member 43 stably and firmly presses the connecting seat 31 onto the base 1 to achieve stable installation of the pump body 2. It should be noted that the first locking component 44 is a bolt or similar component.

[0044] In one implementation, please refer to Figure 2 The outer peripheral wall of the fixing rod 45 is provided with a through hole, which is located on one side of the boss 451. Each of the disassembly and assembly components 4 also includes two second locking members 46. The two outer side walls of the through hole 432 are provided with mounting holes 433. One end of each second locking member 46 protrudes from the outer peripheral wall of the pressing member 43, and the other end of the second locking member 46 passes through the mounting hole 433 and is movably inserted into the through hole to further lock the pressing member 43 to the fixing rod 45, so as to further stably install the pump body 2 on the base 1.

[0045] In one implementation, please refer to Figure 3 and Figure 4 Each of the second locking members 46 includes a mounting housing 461, a first connecting rod 462, and a second connecting rod 463. The mounting housing 461 forms a mounting cavity 4611 with openings 4612 at both ends. One side of the mounting housing 461 is installed in the mounting hole 433, and the other side of the mounting housing 461 protrudes from the outer peripheral wall of the clamping member 43. One side of the first connecting rod 462 passes through the opening 4612 and extends into the mounting cavity 4611, and is connected to one side of the second connecting rod 463. The other side of the second connecting rod 463 passes through another opening 4612 and is movably inserted into the through hole. By rotating the first connecting rod 462, the second connecting rod 463 is driven to rotate, thereby allowing the second connecting rod 463 to be inserted into the through hole, thereby further locking the clamping member 43 onto the fixing rod 45.

[0046] In this embodiment, each second locking member 46 includes a mounting housing 461, a first connecting rod 462, and a second connecting rod 463. The mounting housing 461 forms a mounting cavity 4611 with openings 4612 at both ends. One side of the mounting housing 461 is installed in the mounting hole 433, and the other side of the mounting housing 461 protrudes from the outer peripheral wall of the clamping member 43. It should be noted that the mounting housing 461 can be installed in the mounting hole 433 by welding or other means. One side of the first connecting rod 462 passes through the opening 4612 and extends into the mounting cavity 4611, and is connected to one side of the second connecting rod 463. The other side of the second connecting rod 463 passes through another opening 4612 and is movably inserted into the through hole. That is, by rotating the first connecting rod 462, the second connecting rod 463 is driven to move closer to or away from the fixed rod 45. When it moves closer, the clamping member 43 can be locked onto the fixed rod 45. When it moves away, the clamping member 43 can be removed from the fixed rod 45.

[0047] In one implementation, please refer to Figure 3 and Figure 4 Each of the mounting housings 461 has a connecting hole 4613 on its outer peripheral wall, and the connecting hole 4613 is U-shaped.

[0048] The second connecting rod 463 has a locking protrusion 4631 on the outer peripheral wall of the mounting cavity 4611. The locking protrusion 4631 is slidably connected to the connecting hole 4613. Through the cooperation of the locking protrusion 4631 and the connecting hole 4613, the second connecting rod 463 is stably inserted into the through hole.

[0049] In this embodiment, in order to stably insert the second connecting rod 463 into the through hole, a connecting hole 4613 is provided on the outer peripheral wall of each mounting housing 461. The connecting hole 4613 is connected to the mounting cavity 4611, and the second connecting rod 463 is provided with a locking protrusion 4631 on the outer peripheral wall extending into the mounting cavity 4611. The locking protrusion 4631 slides in the connecting hole 4613. When the first rod is rotated to drive the second connecting rod 463 to rotate, the second connecting rod 463 also drives the locking protrusion 4631 to rotate in the connecting hole 4613. At the same time, the connecting hole 4613 is U-shaped. That is, when the locking protrusion 4631 comes to both ends of the connecting hole 4613, the second connecting rod 463 can be inserted into the through hole. When the locking protrusion 4631 comes to the bottom wall of the groove of the connecting hole 4613, the second connecting rod 463 is withdrawn from the through hole, so that the clamping member 43 can be removed from the fixing rod 45.

[0050] In one implementation, please refer to Figure 3 and Figure 4Each of the second locking members 46 further includes an elastic member 464, one side of which abuts against one side of the first connecting rod 462 extending into the mounting cavity 4611, and the other side of which abuts against one side of the second connecting rod 463 extending into the mounting cavity 4611, so as to stably insert the second connecting rod 463 into the through hole.

[0051] In this embodiment, when the first connecting rod 462 is rotated so that the locking protrusion 4631 reaches both ends of the communicating hole 4613, the elastic force of the elastic member 464 allows the second connecting rod 463 to be inserted into the through hole, thereby locking the clamping member 43 onto the fixing rod 45. When the first connecting rod 462 is rotated so that the locking protrusion 4631 reaches the bottom wall of the groove in the communicating hole 4613, the second connecting rod 463 is withdrawn from the through hole, thereby allowing the clamping member 43 to be removed from the fixing rod 45.
