[0001] This utility model relates to the field of automotive parts technology, and in particular to an easy-to-install automotive water pump impeller base. Background Technology

[0002] The car water pump is a key component in the car engine cooling system. It mainly consists of an impeller, pump body, and bearings. Its function is to pressurize the coolant and promote its circulation in the engine cooling system. Through this circulation, the coolant can continuously absorb the heat generated by the engine during operation and carry it to the radiator, thereby keeping the engine within a suitable operating temperature range.

[0003] As the automotive market continues to expand and automotive production efficiency continues to improve, the installation efficiency of automotive water pumps, as an important component of the engine cooling system, is directly related to the production progress of the entire vehicle. However, the traditional installation method of automotive water pump impeller base is often quite complicated, which is why an easy-to-install automotive water pump impeller base is needed.

[0004] Existing easy-to-install car water pump impeller bases often use multiple bolts for fixing during installation. This requires tightening multiple bolts to complete the installation, which is inconvenient for quick installation, reduces the work efficiency of workers, and fails to meet the needs of users. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an easy-to-install automotive water pump impeller base, aiming to improve the problem that existing automotive water pump impeller bases, which are easy to install, are not convenient for quick installation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a car water pump impeller base that is easy to install, including a base ring, a mounting ring fixedly connected to the rear side of the base ring, an inner cavity opened inside the mounting ring, a transmission column rotatably connected to the lower left side of the mounting ring, a worm gear fixedly connected to the left end of the transmission column through the mounting ring, a transmission rod rotatably connected to the right side inside the inner cavity, a worm wheel fixedly connected to the rear side of the outer wall of the transmission rod, the worm wheel meshing with the worm gear, a first gear fixedly connected to the front side of the outer wall of the transmission rod, an annular rack rotatably connected inside the inner cavity, multiple bolts rotatably connected at equal intervals around the front end of the inner cavity, a second gear fixedly connected to the rear end of each of the multiple bolts, multiple second gears meshing with the inner side of the same annular rack, the front ends of the multiple bolts sequentially penetrating the mounting ring and the base ring, and a positioning mechanism provided at the bottom right side of the base ring, the positioning mechanism being used to facilitate the positioning of the car water pump.

[0007] As a further description of the above technical solution:

[0008] The positioning mechanism includes a fixing block, which is fixedly connected to the bottom right side of the base ring. A hollow shell is rotatably connected to the bottom right side of the rear wall of the fixing block. A threaded rod is fixedly connected to the rear end of the hollow shell. A positioning pin is threadedly connected to the outer side of the threaded rod. A limit ring is provided at the front end of the hollow shell. The front end of the limit ring passes through the hollow shell and is fixedly connected to the rear side of the fixing block. The front end of the positioning pin passes through the limit ring and the fixing block in sequence and is fixedly connected to a positioning cone. Slider blocks are fixedly connected to the upper and lower sides of the limit ring. Sliding grooves are provided on the upper and lower sides of the positioning pin. The sliding grooves are slidably connected to the corresponding sliders.

[0009] As a further description of the above technical solution:

[0010] A protective ring is fixedly connected inside the base ring, and a fixing ring is fixedly connected inside the protective ring.

[0011] As a further description of the above technical solution:

[0012] A heat sink is fixedly connected to the rear end of the protective ring, and a heat sink cover is fixedly connected to the rear end of the heat sink.

[0013] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] A rotating disk is fixedly connected to the right end of the transmission column, and multiple handles are fixedly connected at equal intervals around the outer perimeter of the rotating disk.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, the transmission column is rotated first, which drives the worm to rotate. Since the worm wheel and the worm mesh with each other, the worm wheel drives the first gear to rotate through the transmission rod. Since the ring rack meshes with the first gear, and the second gear meshes with the ring rack, the first gear can drive multiple bolts to rotate through the ring rack. The rotating bolts will move backward and be fixed to the water pump housing, making the fixing work more convenient, improving the work efficiency of the staff, and meeting the needs of the user.

[0023] 2. In this utility model, rotating the hollow shell causes the threaded rod to rotate. When the threaded rod rotates, the positioning pin moves forward. When the positioning pin moves forward, it causes the positioning cone to insert into the positioning hole on the car water pump housing, thus aligning the impeller base with the water pump housing. This eliminates the need for workers to align multiple holes, simplifying the operation steps and reducing the workload of workers. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 and Figure 2 This utility model provides an embodiment of an easy-to-install automotive water pump impeller base, comprising a base ring 1, a mounting ring 3 fixedly connected to the rear side of the base ring 1, an inner cavity 4 inside the mounting ring 3, a transmission column 5 rotatably connected to the lower left side of the mounting ring 3, the left end of the transmission column 5 passing through the mounting ring 3 and fixedly connected to a worm gear 6, a transmission rod 7 rotatably connected to the right side inside the inner cavity 4, a worm wheel 8 fixedly connected to the rear side of the outer wall of the transmission rod 7, the worm wheel 8 meshing with the worm gear 6, a first gear 9 fixedly connected to the front side of the outer wall of the transmission rod 7, and a rotatable transmission rod 7 rotatably connected to the inner cavity 4. A ring rack 10 is attached. Multiple bolts 11 are equidistantly rotatably connected around the front end of the inner cavity 4. The rear ends of the multiple bolts 11 are all fixedly connected to a second gear 12. The multiple second gears 12 are all meshed with the inner side of the same ring rack 10. The front ends of the multiple bolts 11 pass through the mounting ring 3 and the base ring 1 in sequence. A positioning mechanism 2 is provided at the bottom right side of the base ring 1. The positioning mechanism 2 is used to facilitate the positioning of the car water pump. A rotating disk 21 is fixedly connected to the right end of the transmission column 5. Multiple handles 22 are fixedly connected equidistantly around the outer periphery of the rotating disk 21.

[0033] Specifically, when installing the impeller base of the car water pump, first turn the handle 22. At this time, the rotating disk 21 also starts to rotate. During the rotation of the rotating disk 21, it will drive the transmission column 5 to rotate synchronously. The rotation of the transmission column 5 will further drive the worm 6 to rotate. Since the worm wheel 8 meshes with the worm 6, when the worm 6 rotates, the worm wheel 8 will drive the transmission rod 7 to rotate along with the rotation of the worm 6. When the transmission rod 7 rotates, it will drive the first gear 9 to rotate. At this time, since the ring rack 10 meshes with the first gear 9, when the first gear 9 rotates, the ring rack 10 will rotate accordingly. Since multiple second gears 12 mesh with the ring rack 10, when the ring rack 10 rotates, the multiple second gears 12 will drive the bolts 11 to rotate. When the bolts 11 rotate, they will move forward and eventually connect with the water pump housing, thus firmly fixing the impeller base of the car water pump. This greatly improves the convenience of installation, makes the fixing of the impeller base more convenient, improves the work efficiency of the staff, and meets the needs of users.

[0034] Reference Figure 1 , Figure 3 and Figure 4 The positioning mechanism 2 includes a fixing block 201, which is fixedly connected to the bottom right side of the base ring 1. A hollow shell 202 is rotatably connected to the bottom right side of the rear wall of the fixing block 201. A threaded rod 203 is fixedly connected to the rear end of the hollow shell 202. A positioning pin 204 is threadedly connected to the outer side of the threaded rod 203. A limit ring 205 is provided at the front end of the hollow shell 202. The front end of the limit ring 205 passes through the hollow shell 202 and is fixedly connected to the rear side of the fixing block 201. The front end of the positioning pin 204 passes through the limit ring 205 and the fixing block 201 in sequence and is fixedly connected to a positioning cone 208. A slider 206 is fixedly connected to both the upper and lower sides of the inside of the limit ring 205. A groove 207 is provided on both the upper and lower sides of the positioning pin 204. The groove 207 is slidably connected to the corresponding slider 206.

[0035] Specifically, during the installation of the car water pump impeller base, the hollow shell 202 is rotated first. This rotation directly drives the threaded rod 203 to rotate. Since the upper and lower sides of the positioning pin 204 are provided with sliding grooves 207, and the inner side of the limiting ring 205 is provided with a slider 206, the sliding groove 207 is limited by the slider 206. When the threaded rod 203 rotates, the positioning pin 204 moves forward along the threaded rod 203. When the positioning pin 204 moves forward, it drives the positioning cone 208 connected to it to move forward together. When the positioning pin 204 and the positioning cone 208 move forward together and insert into the positioning hole on the car water pump housing, the impeller base can be aligned with the water pump housing, which greatly simplifies the operation steps of the staff and reduces the workload of the staff.

[0036] Reference Figure 1 and Figure 5 The base ring 1 is fixedly connected to a protective ring 13, the protective ring 13 is fixedly connected to a fixing ring 14, the rear end of the protective ring 13 is fixedly connected to a heat sink 19, and the rear end of the heat sink 19 is fixedly connected to a heat sink cover 20.

[0037] Specifically, the protective ring 13 can provide protection for the first impeller 17, and the fixing ring 14 can be used to fix the rotating shaft 15. The heat sink 19 can be used to dissipate heat from the device, and the heat sink cover 20 can provide protection for the heat sink 19.

[0038] Reference Figure 1 and Figure 5The front inner side of the fixed ring 14 is rotatably connected to the rotating shaft 15, and the rear inner side of the fixed ring 14 is fixedly connected to the sealing ring 18. The rotating shaft 15 is fixedly connected to the drive shaft 16, and the front end of the drive shaft 16 is fixedly connected to the first impeller 17. The rear end of the drive shaft 16 passes through the sealing ring 18, the heat sink 19, and the heat sink cover 20 in sequence. The internal size of the sealing ring 18 matches the external size of the drive shaft 16, and the internal size of the fixed ring 14 matches the external size of the sealing ring 18.

[0039] Specifically, the sealing ring 18 can improve the sealing performance of the device. The first impeller 17 is used to provide water supply power to the water pump, and the drive shaft 16 is used to drive the impeller to rotate. The internal size of the sealing ring 18 matches the external size of the drive shaft 16, and the internal size of the fixing ring 14 matches the external size of the sealing ring 18, ensuring that there are no gaps between the sealing ring 18, the drive shaft 16, and the fixing ring 14, thereby improving the sealing performance.

[0040] Working principle: When installing the impeller base of the car water pump, first turn the handle 22. The handle 22 will drive the rotating disk 21 to rotate. When the rotating disk 21 rotates, it will drive the transmission column 5 to rotate. At this time, the worm 6 will rotate accordingly. Since the worm wheel 8 and the worm 6 mesh with each other, when the worm 6 rotates, the worm wheel 8 will drive the transmission rod 7 to rotate together. The rotation of the transmission rod 7 will drive the first gear 9 to rotate. Since the ring rack 10 meshes with the first gear 9, the ring rack 10 will rotate accordingly. Since multiple second gears 12 mesh with the ring rack 10, when the ring rack 10 rotates, the multiple second gears 12 will drive the bolts 11 to rotate respectively. When the multiple bolts 11 rotate, they will move forward and connect tightly with the water pump housing. At this time, the impeller base of the car water pump can be firmly fixed, making the fixing work more convenient.

[0041] Furthermore, during the installation of the car water pump impeller base, the hollow shell 202 is rotated, which in turn drives the threaded rod 203 to rotate. Since the positioning pin 204 has sliding grooves 207 on its upper and lower sides and a slider 206 is set inside the limiting ring 205, the sliding groove 207 is limited by the slider 206. When the threaded rod 203 rotates, the positioning pin 204 will move forward accordingly. When the positioning pin 204 moves forward, it will drive the positioning cone 208 to move forward together. When the positioning pin 204 and the positioning cone 208 move forward together and insert into the positioning hole on the car water pump housing, the impeller base can be aligned with the water pump housing. This eliminates the need for workers to align multiple holes, simplifying the operation process.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
