Description

Technical Field

[0001] This utility model relates to the field of automotive water pump technology, specifically an automotive water pump with an anti-loosening structure. Background Technology

[0002] Inside the engine block of a car, there are multiple water channels for cooling water circulation. These channels are connected to the radiator (commonly known as the water tank) located at the front of the car via water pipes, forming a large water circulation system. A water pump is installed at the upper outlet of the engine, driven by a fan belt, to pump hot water out of the engine block's water channels and pump cold water in. Next to the water pump is a thermostat. When the car is first started (cold engine), it does not open, allowing the coolant to circulate only within the engine, bypassing the water tank (commonly known as the small circulation). Once the engine temperature reaches above 95 degrees Celsius, it opens, pumping the hot water from the engine into the water tank. The cool air from the car as it moves forward blows across the water tank, carrying away the heat.

[0003] The current automotive water pumps are installed using bolts, which results in a fixed bracket structure. This means the bracket can only accommodate pumps of a specific size, making it unsuitable for pumps of various sizes. This limits its installation and use. Furthermore, the bolts can loosen due to vibration after installation, affecting the subsequent use of the water pump. Utility Model Content

[0004] The purpose of this utility model is to provide a car water pump with an anti-loosening structure to solve the problem mentioned in the background art that current car water pumps are installed and used by fixing them with bolts. This fixed bracket structure means that the fixed bracket can only be installed for pumps of a certain size, and cannot be adapted to pumps of various sizes, which limits the installation and use. At the same time, the bolts will vibrate and loosen after fixing, affecting the subsequent use of the water pump.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A car water pump with an anti-loosening structure includes a supporting base plate. The top surface of the supporting base plate has symmetrically formed mounting holes and a through-slot. A main body is vertically inserted into the inner side of the through-slot. A connector is fixedly mounted at the top of the main body. A pressing inner block is engaged with the inner side of the through-slot. A protective adhesive block is fixedly adhered to one side of the pressing inner block. A mating bottom block is fixedly connected to the bottom of the main body. A transmission pipe is horizontally fixedly connected to the side of the mating bottom block. A side locking hole is provided on one side of the device, and a rotating block is locked onto the inner side of the side locking hole. A through hole is horizontally provided on the inner end of the side locking hole, and a pressing screw is horizontally inserted into the inner side of the through hole. A limit retaining ring is welded to the outer side of the pressing screw. A mating screw hole is provided on the outer arc-shaped surface of the pressing inner block. A flipping block is evenly locked onto the outer side of the rotating block. An inner limit hole is evenly provided on the inner side of the side locking hole. A flipping shaft is inserted into the side of the flipping block, and a support spring is fixedly sleeved on the outer side of the flipping shaft.

[0007] In a preferred embodiment of this utility model: the mounting holes are symmetrically and through-holes on the top surface of the support base plate near the four corners, the through slot is through-hole at the center of the top surface of the support base plate, and the main body is vertically inserted into the inner side of the through slot.

[0008] In a preferred embodiment of this utility model: the interior of the connector is electrically connected to the interior of the main body, the protective rubber block is made of hard rubber material, and the protective rubber block is fixedly set on the side of the extrusion inner block and the inner side of the through groove, and is connected to the interior of the bottom block and the connector end of the transmission pipe.

[0009] As a preferred embodiment of this utility model: the side card hole is opened at the center of one side of the support base plate, one end of the rotating block is provided with a polygonal hole structure, and the other end is horizontally fixedly connected to one end of the extrusion screw. The through hole is opened horizontally through, and the extended end is connected to the inside of the through groove.

[0010] In a preferred embodiment of this utility model: one end of the extrusion screw is horizontally threaded and set on the inner side of the mating screw hole, the limiting retaining ring is snapped into the inner channel of the through hole, the mating screw hole is opened at the center of the outer arc surface of the extrusion inner block, there are multiple flipping retaining blocks, and each flipping retaining block is snapped into the side wall channel of the rotating block. One end of the flipping retaining block extends and is snapped into the inner side of the inner limiting hole, and the other end extends into the polygonal groove of the rotating block.

[0011] In a preferred embodiment of this utility model: the inner limiting holes are arranged in a ring at equal intervals on the inner side of the side locking holes, the two ends of the flipping shaft are horizontally inserted into the side wall groove of the rotating block, and the support spring is fixedly locked at the two ends of the outer side of the flipping shaft.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention fixes the support base plate horizontally at the designated location on the vehicle, allowing bolts to pass through the mounting holes for secure installation. The main body is inserted through a through slot, with one side of the main body aligned with the side of the protective rubber block. A corresponding tool is inserted into the polygonal hole at one end of the rotating block, causing the tool to press against the flipping block and rotate. This causes the outer end to flip away from the inner limit hole. Rotating the tool then rotates the rotating block, aligning the pressing screw with the mating screw hole. The interlocking threads cause the inner extrusion block to press against the side of the main body, thus clamping and fixing the main body inside the through slot. This allows for a secure installation of the main body. When the tool is pulled outward, the support spring causes the flipping block to flip outward. The flipping end engages with the corresponding inner limit hole to create a limiting effect and effectively prevent the rotating block from rotating. The extrusion-type fixing installation structure allows for the installation of water pumps of various sizes, and the limiting structure effectively prevents rotation and loosening after extrusion fixing.

The inner channel is located at the center of the outer arc-shaped surface of the inner extrusion block 6, and there are multiple flipping blocks 16. Each flipping block 16 is correspondingly engaged with the side wall channel of the rotating block 11. One end of the flipping block 16 extends and is engaged with the inner side of the inner limiting hole 17, and the other end extends into the polygonal groove of the rotating block 11.
