Description

Technical Field

[0001] This utility model belongs to the field of water pump assembly technology, specifically a cooling water pump that is easy to assemble and disassemble. Background Technology

[0002] A cooling water pump is a mechanical device used to transport coolant in a cooling system. It is widely used in various industrial and commercial fields, such as high-rise building water supply, boiler feedwater, HVAC refrigeration cycles, and automotive engine cooling systems. The working principle of a cooling water pump is relatively simple and efficient. When the pump starts, its internal impeller rotates at high speed. With the pump body filled with liquid, the rotation of the impeller drives the coolant in the pump body to rotate as well. Due to centrifugal force, the coolant is thrown out of the pump body by the impeller and enters the diffuser chamber. In the diffuser chamber, the speed of the coolant gradually decreases, and the pressure gradually increases, eventually forming a certain pressure difference. This pressure difference causes the coolant to flow out from the outlet and into the cooling system. At the same time, a vacuum low-pressure zone is formed at the center of the impeller, and the coolant in the liquid pool, under the action of atmospheric pressure, enters the pump through the suction pipe, forming a continuous circulation.

[0003] In the existing technology, cooling water pumps are fastened to the fixed seat with bolts during use and assembly. This is cumbersome to operate, and over time the bolts will corrode, making disassembly and assembly difficult or even causing the bolts to break. Utility Model Content

The lock pin 22 is in the shape of a barb as a whole, and can cooperate with the top surface of the support seat 11 after passing through the locking hole 13, so as to limit the displacement of the support seat 11 in the vertical direction.

[0030] The lock pin 22 passes through the locking hole 13 and installs the support seat 11 on the fixed seat 20 under the action of elastic deformation, when disassembling, the push rod 32 is moved to the locked position, the lock pin 22 is completely pushed into the covering area of the locking hole 13, then the water pump body 10 is moved upward, so that the support seat 11 and the fixed seat 20 can be separated, and the disassembly efficiency is improved significantly.

[0031] Specifically, the support frame 31 is provided with a stop protrusion 312, the push rod 32 is provided with a stop groove 322 which can be matched with the stop protrusion 312 and limit the position of the push rod 32 in the locked position, and the stop groove 322 is on the side of the push rod 32 close to the support seat 11. The stop groove 322 can cooperate with the stop protrusion 312 to complete the position locking of the push rod 32 relative to the support frame 31.

[0032] Specifically, the push rod 32 is provided with a guide groove 323 communicating with the stop groove 322 and matched with the stop protrusion 312 to restrict the moving direction of the push rod 32; the depth of the guide groove 323 is less than that of the stop groove 322. The guide groove 323 cooperates with the stop protrusion 312 to limit the moving track of the push rod 32 relative to the support frame 31, and the depth of the guide groove 323 is different from that of the stop groove 322, so as to prevent the push rod 32 from being easily changed from the locked state in the support frame 31.

[0033] Specifically, the support frame 31 is provided with an assembly gap 311 facilitating the assembly of the push rod 32 into the support frame 31.

The space height allowing the push rod 32 to pass through the support frame 31 is matched with the thickness of the push rod 32.

[0034] Specifically, the push rod 32 is located on one side of the barb protrusion of the locking pin 22.

[0035] Specifically, the guide groove 323 is located on the side of the stop groove 322 close to the knob 33.

[0036] Specifically, the push rod 32 is provided with a compression spring 34; one end of the compression spring 34 is fixed to the end of the push rod 32 away from the knob 33, and the other end abuts against the support frame 31. The state of the push rod 32 is adjusted so that the stop groove 322 is separated from the stop protrusion 312, and the push rod 32 is quickly reset under the action of the spring. The end of the push rod 32 away from the knob 33 is provided with a handle 35, facilitating the operation of the end of the push rod 32.

[0037] Specifically, the fixed seat 20 is provided with a guide rod 21 corresponding to the moving track of the push rod 32, and the support seat 11 is provided with a guide hole 12 allowing the guide rod 21 to pass through and abutting against the push rod 32 to unlock the push rod 32 from the locked position. The cooperation of the guide hole 12 and the guide rod 21 can improve the assembly accuracy of the support seat 11 on the fixed seat 20.

[0038] Specifically, the height of the guide rod 21 is greater than the thickness of the support seat 11 and the depth of the stop groove 322. When the guide rod 21 passes through the guide hole 12 upward, the guide rod 21 pushes the push rod 32 and makes the stop groove 322 separate from the stop protrusion 312.

[0039] Specific, the said toggle piece 33 is a frame structure set outside the locking hole 13, which can be in contact with the locking pin 22 to form a state of keeping the locking pin 22 and the support seat 11 locked when the push rod 32 is in the non-locking position. The locking pin 22 passes through the locking hole 13 to complete the locking installation of the support seat 11 on the fixed seat 20. Under the action of the compression spring 34, the toggle piece 33 continuously pulls the locking pin 22, that is, a part of the locking pin 22 is in the coverage area of the locking hole 13, and another part is outside the coverage area of the locking hole 13.

[0040] Specific, the side wall of the locking pin 22 is provided with a limiting step 221; the toggle piece 33 is provided with a linkage protrusion 331 capable of abutting against the limiting step 221 to form an unlocked state of the locking pin 22.

When assembling, the locking pin 22 and the guide rod 21 pass through the locking hole 13 and the guide hole 12 respectively, the guide rod 21 pushes up the push rod 32, the stop groove 322 is separated from the stop protrusion 312, and the push rod 32 is pulled tightly by the toggle piece 33 to the locking pin 22 under the rebound action of the compression spring 34; first, the locking hole 13 pushes the locking pin 22 to deform to make the locking pin 22 pass through the locking hole 13 smoothly, and the barb protrusion on the locking pin 22 deforms to reset after passing through the locking hole 13.

[0043] When the sliding push rod 32 is locked in the support frame 31, that is, the stop groove 322 cooperates with the stop protrusion 312, the linkage protrusion 331 pushes the limiting step 221 and makes the outer edge of the locking pin 22 completely in the coverage range of the locking hole 13 in the plane, and the support seat 11 and the fixed seat 20 can be directly separated upward.

[0044] The utility model discloses a cooling water pump convenient to dismount, and the locking pin passes through the locking hole and installs the support seat on the fixed seat under the elastic deformation effect, when disassembling, the locking pin is completely pushed into the coverage area of the locking hole by moving the push rod to the locking position, then the pump body is moved upward, the support seat and the fixed seat are separated, and the dismounting efficiency is improved significantly.
