Description

Technical Field

[0001] This utility model relates to the field of filter technology, and in particular to a filter element installation structure for a water filter. Background Technology

[0002] A search revealed Chinese patent CN220918407U, which discloses a filter element installation structure. This structure primarily addresses the problem that some cylindrical filter elements use a threaded fixing method, which can lead to wear on the threads during installation and disassembly, affecting the secure fixing of the filter element after replacement. The proposed solution includes a mounting plate with mounting holes; a filter element installed in the mounting holes, with a sealing ring at the contact point between the filter element and the mounting plate; and a fixing component located on the top of the mounting plate, which presses and fixes the filter element to the mounting plate, ensuring a good seal between the filter element and the sealing ring. This invention allows for quick installation and fixing of the filter element, while maintaining a good seal between the filter element and the mounting plate, and does not hinder the removal of the filter element when replacement is needed.

[0003] The aforementioned patent has the following shortcomings: the movable plate is adjusted by the cooperation of the screw and threaded sleeve in the fixing component, and then the filter element is pressed by the pressure plate. The screw and threaded sleeve are used in this process. If the maintenance is not done properly after long-term use, the threads may strip, which may cause the filter element to loosen in subsequent use and make the filter element installation unstable. Therefore, it is urgent to solve this problem. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a water filter cartridge installation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A water filter cartridge installation structure includes a mounting plate, with mounting holes at the top and bottom of the mounting plate, and a filter cartridge installed in the mounting holes. The top of the mounting plate is provided with an installation mechanism for pressing and installing the filter cartridge, and the top two sides of the mounting plate are provided with limiting mechanisms for limiting the installation mechanism.

[0007] The installation mechanism includes a U-shaped fixing frame, with sliding rods fixed to both sides of the top of the U-shaped fixing frame. A fixing plate is provided at one end of each sliding rod, and a mounting block is fixed to the bottom of the fixing plate near the sliding rod. The mounting block has through holes at its top and bottom, and the sliding rod slides in the through holes. A connecting plate is fixed to the bottom of the other end of the fixing plate, and a connecting block is fixed to the bottom of the connecting plate. A pressure plate is fixed to the bottom of the connecting block. Reinforcing ribs are fixed to both sides of the top of the connecting plate, and one end of the reinforcing rib is fixedly connected to one end of the fixing plate. Limiting holes are provided on both sides of the connecting plate. Anti-detachment caps are fixed to the top of both sliding rods. When the fixing plate moves down, it can press and fix the top of the filter element.

[0008] Preferably, one end of a first spring is fixed to the bottom of the two mounting blocks, the other end of the first spring is fixedly connected to the top of the U-shaped fixing bracket, and the first spring is located on the outer surface of the slide rod.

[0009] Preferably, the top end of the mounting plate is provided with grooves on both sides, and a slider is slidably provided inside the groove, with the top of the slider fixed to the bottom of the U-shaped fixing frame.

[0010] Preferably, the limiting mechanism includes a housing fixed to both sides of the top of the mounting plate, and a movable block is slidably provided inside the housing. A movable rod is slidably provided through the top two sides of the movable block. A limiting block is fixed at one end of the movable rod near the connecting plate, and the top of the limiting block is arc-shaped.

[0011] Preferably, one end of the second spring is fixed to one end of the limiting block near the moving block, and the other end of the second spring is fixedly connected to one side of the moving block. The second spring is located outside the moving rod. The limiting block can limit the connecting plate and prevent the filter element from loosening.

[0012] Preferably, the housing has several through holes on both sides, and the movable block has threaded holes on both sides, with a suitable fixing bolt in the threaded hole. The other end of the fixing bolt is provided with a suitable nut. The fixing bolt passes through the through hole to limit the movable block. When it moves away, the height of the movable block can be easily adjusted, thereby adjusting the degree of compression on the filter element.

[0013] Preferably, a sealing gasket is provided at the contact position between the filter element and the mounting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. Due to the adoption of the installation mechanism, when replacing a new filter element, the pressure plate is moved above the filter element, and then the fixing plate is pressed. The fixing plate will drive the connecting plate to move and contact the top side of the limiting block. Then the limiting block will limit the connecting plate. When the limiting block moves away from the limiting hole, the first spring will automatically drive the connecting plate away from the filter element, thereby achieving the effect of convenient installation and removal of the filter element, saving the time required for installation and removal, improving the efficiency of filter element replacement, ensuring the stability of the connecting plate, avoiding unexpected situations during operation, and improving safety.

[0016] 2. Due to the adoption of a limiting mechanism, by adjusting the height of the moving block and then using a fixing bolt to fit the through hole and threaded hole to limit the moving block, the height of the moving block can be adjusted. Users can freely adjust the height of the limiting block and adjust the tightness of the filter element, increasing the flexibility in this field. It is simple to operate and highly practical.

The top of the mounting plate 1 is provided with an installation mechanism for pressing and installing the filter cartridge 2, and the top two sides of the mounting plate 1 are provided with limiting mechanisms for limiting the installation mechanism.

[0024] The installation mechanism includes a U-shaped fixing frame 3. Slide rods 305 are fixed on both sides of the top of the U-shaped fixing frame 3. A fixing plate 301 is provided at one end of the slide rod 305. An installation block 304 is fixed at the bottom of the end of the fixing plate 301 near the slide rod 305. The top and bottom of the installation block 304 are provided with through holes, and the slide rod 305 is slidably disposed in the through holes. A connecting plate 302 is fixed at the bottom of the other end of the fixing plate 301. A connecting block 309 is fixed at the bottom of the connecting plate 302. A pressure plate 308 is fixed at the bottom of the connecting block 309. When the fixing plate 301 moves down, it can press and fix the top of the filter element 2. Reinforcing ribs 303 are fixed on both sides of the top of the connecting plate 302. One end of the reinforcing rib 303 is fixedly connected to one end of the fixing plate 301. Limiting holes 3020 are provided on both sides of the connecting plate 302. Anti-detachment caps 306 are fixed on the top of both slide rods 305.

[0025] In this utility model, one end of the first spring 307 is fixed to the bottom of the two mounting blocks 304, the other end of the first spring 307 is fixedly connected to the top of the U-shaped fixing bracket 3, and the first spring 307 is located on the outer surface of the slide rod 305.

[0026] In this utility model, the top end of the mounting plate 1 is provided with sliding grooves 101 on both sides, and a slider 300 is slidably provided inside the sliding groove 101. The top of the slider 300 is fixed to the bottom of the U-shaped fixing frame 3.

[0027] In this utility model, the limiting mechanism includes a housing 4 fixed on both sides of the top of the mounting plate 1. A movable block 402 is slidably provided inside the housing 4. A movable rod 404 is slidably provided through both sides of the top of the movable block 402. A limiting block 403 is fixed at one end of the movable rod 404 near the connecting plate 302, and the top of the limiting block 403 is arc-shaped.

[0028] In this utility model, one end of the second spring 405 is fixed to one end of the limiting block 403 near the moving block 402, and the other end of the second spring 405 is fixedly connected to one side of the moving block 402. The second spring 405 is located outside the moving rod 404. The limiting block 403 can limit the connecting plate 302 to prevent the filter element 2 from loosening.

[0029] In this utility model, the housing 4 has several through holes 401 on both sides, and the movable block 402 has threaded holes 4020 on both sides. The threaded holes 4020 are equipped with matching fixing bolts 406, and the other end of the fixing bolts 406 is equipped with matching nuts 4060. The fixing bolts 406 can limit the movable block 402 by passing through the through holes 401. When it is far away, the height of the movable block 402 can be easily adjusted, thereby adjusting the degree of compression on the filter element 2.

[0030] In this utility model, a sealing gasket 201 is provided at the contact position between the filter element 2 and the mounting plate 1.

[0031] Working principle: When the filter element 2 needs to be removed, pull the two moving rods 404. The moving rods 404 will move the limiting block 403 away from the limiting hole 3020 and away from the connecting plate 302. At this time, the first spring 307 will reset the mounting block 304 and lift it. Then the mounting block 304 will move the fixing plate 301 away from the top of the filter element 2. Then the fixing plate 301 will move the reinforcing rib 303 upward and move the pressure plate 308 away from the filter element 2. When the pressure plate 308 is away from the filter element 2, move the U-shaped fixing bracket 3. The U-shaped fixing bracket 3 will move the slider 300 to slide in the slide groove 101 and away from one end of the filter element 2. Then the filter element 2 is taken out, and then the new filter element 2 is placed in the mounting groove of the mounting plate 1. Then the U-shaped fixing bracket 3 is moved above the filter element 2. Pressing down the fixing plate 301 causes the pressure plate 308 to move downwards, which in turn compresses the filter element 2, pressing it tightly against the sealing gasket 201, thus ensuring good sealing performance. When the connecting plate 302 moves downwards, it compresses the arc-shaped surface of the limiting block 403. When the limiting block 403 is aligned with the limiting hole 3020, the second spring 405 resets the limiting block 403, inserting it into the limiting hole 3020 and limiting the connecting plate 302. By moving the moving block 402 inside the housing 4, the height of the limiting block 403 can be adjusted. The moving block 402 is then limited by the fixing bolts 406 and nuts 4060, thereby indirectly adjusting the tightness of the filter element 2 and facilitating the adjustment of the filter element 2's installation tightness.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
