Description

Technical Field

[0001] This utility model relates to the field of pressure sensor mounting technology, specifically a pressure sensor for a water pump pressure controller. Background Technology

[0002] A pressure sensor used in a water pump pressure controller is a device that converts pressure signals in a water pump system into electrical signals. It senses pressure changes in the water pump system and converts the pressure signal into a readable electrical signal, enabling the control system to process and interpret the data, thereby achieving automatic control and protection of the water pump.

[0003] According to Chinese Patent CN201821651587.2, a rubber washer is connected to the bottom of the mounting hole. The surface of the rubber washer is engraved with anti-slip texture, which provides a cushioning effect and enhances the stability of the connection between the threaded head and the wall of the mounting hole, making it less prone to loosening.

[0004] Although the rubber gasket in the application can effectively address the loosening problem, the installation process is relatively cumbersome due to the complex design of the protective housing of some pressure sensors. It requires specific tools and techniques, increasing the difficulty and time cost of installation. Therefore, we propose a pressure sensor for a water pump pressure controller.

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.

[0022] Please see Figure 1-3 A pressure sensor for a water pump pressure controller includes a sensor body 1, a protective housing 2, a mounting base 3, and a fixing block 4. The protective housing 2 is movably connected to the outer side of the sensor body 1, the fixing block 4 is movably connected to the bottom of the protective housing 2, and the mounting base 3 is fixedly connected to the bottom of the fixing block 4. The sensor body 1 also includes:

[0023] An easy-to-install and disassemble structure is provided inside the protective housing 2, which is used to replace the protective housing 2;

[0024] A fixing structure is provided at the bottom of the protective housing 2, which is used to fix the protective housing 2.

[0025] Furthermore, the structure for easy installation and disassembly includes a flat-top conical block 15, a connecting column 16, a limiting block 17, and a second placement groove 19. The top of the protective housing 2 is provided with a second placement groove 19. The inner wall of the second placement groove 19 is movably connected to the flat-top conical block 15. The top of the flat-top conical block 15 is fixedly connected to the connecting column 16. The outer side of the connecting column 16 is fixedly connected to the limiting block 17. The top of the connecting column 16 is fixedly connected to the bottom of the sensor body 1. The flat-top conical block 15 is aligned with the second placement groove 19 and pushed in. The auxiliary block 7 is released. Under the action of the spring 13, the fixing wedge block 14 is pushed between the flat-top conical block 15 and the limiting block 17, thereby facilitating the installation of the protective housing 2.

[0026] Furthermore, the inner wall of the second placement groove 19 is provided with two sets of first placement grooves 12, and the inner walls of the two sets of first placement grooves 12 are fixedly connected with fixed wedge blocks 14. One end of the fixed wedge block 14 is inserted into the bottom of the limiting block 17 and the top of the flat-top conical block 15.

[0027] Furthermore, a moving rod 11 is fixedly connected to the other end of the fixed wedge block 14. A spring 13 is sleeved on the outside of the moving rod 11. A pull block 6 is fixedly connected to one end of the moving rod 11. One end of the pull block 6 is movably connected to the outside of the protective shell 2. Two sets of auxiliary blocks 7 are fixedly connected to both sides of the pull block 6. When the user pulls the auxiliary block 7, the pull block 6 moves, and the moving rod 11 moves the fixed wedge block 14 into the first placement slot 12. The function of the spring 13 is to push the fixed wedge block 14 back to its original position after the pull block 6 is released, so as to ensure the stable installation of the protective shell 2.

[0028] Furthermore, the fixing structure includes a threaded rod 8, a nut 9, and a fixing groove 10. Two sets of fixing grooves 10 are provided on the outer side of the protective shell 2. The inner walls of the two sets of fixing grooves 10 are movably connected to the threaded rod 8, and the outer side of the threaded rod 8 is fitted with a nut 9. The bottom of the nut 9 is movably connected to the top of the protective shell 2. When the user needs to fix the protective shell 2, the threaded rod 8 is rotated to be vertical and contacts the inner wall of the fixing groove 10, and locked by the nut 9. Since the bottom of the nut 9 is movably connected to the top of the protective shell 2, the stability of the protective shell 2 can be ensured by adjusting the position of the nut 9. With this structure, the user can adjust the position of the protective shell 2 as needed and ensure that it will not loosen or move by tightening the nut 9. The two sets of fixing structures are for better fixing of the protective shell.

[0029] Furthermore, the top of the fixed block 4 is provided with two sets of movable grooves 5, and the inner walls of the two sets of movable grooves 5 are sleeved with sleeve shafts 18 through fixed shafts. The top of the sleeve shafts 18 is fixedly connected to the bottom of the threaded rod 8.

[0030] Working principle:

[0031] When the user pulls the auxiliary block 7, causing the pull-out block 6 to move, the moving rod 11 will move the fixed wedge block 14 into the first placement slot 12, aligning the flat-topped conical block 15 with the second placement slot 19 and pushing it in. Releasing the auxiliary block 7, under the action of the spring 13, pushes the fixed wedge block 14 between the flat-topped conical block 15 and the limiting block 17, thus facilitating the installation of the protective shell 2. The function of the spring 13 is to push the fixed wedge block 14 back to its original position after releasing the pull-out block 6, ensuring the secure installation of the protective shell 2. When the user wants to replace the protective shell 2, pulling the auxiliary block 7 will cause the pull-out block 6 to move, and the moving rod 11 will move the fixed wedge block 14 into the first placement slot 12. Pull out 1 to complete disassembly; when the user needs to fix the protective housing 2, rotate the threaded rod 8 to vertical position, movably connect it to the inner wall of the fixing groove 10, and lock it with the help of nut 9. Since the bottom of nut 9 is movably connected to the top of protective housing 2, the stability of protective housing 2 can be ensured by adjusting the position of nut 9. With this structure, the user can adjust the position of protective housing 2 as needed and ensure that it will not loosen or move by tightening nut 9. In summary, this device, through its innovative installation and disassembly structure and fixing structure, allows users to easily install, disassemble, and fix protective housing 2, thereby improving the flexibility and reliability of sensor use.
