[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0030] See also Figures 1 to 4As shown, the utility model is a lubricating oil filter, comprising a housing 1 and a filter element 103 sealed and mounted on one side of the housing 1, through grooves 104 are provided on the top and bottom of one side of the outer wall of the housing 1, and a left buffer component 2 and a right buffer component 3 are respectively provided on both sides of the filter element 103. The filter element 103 is one of the main components of the filter, which is a prior art, so it will not be described in detail here;

[0031] The left buffer assembly 2 includes a sealing ring 201 and a left telescopic rod 202 evenly spaced along the circumferential direction and mounted on the outer wall thereof. A left buffer spring 203 is sleeved on the outer side of the outer wall of the left telescopic rod 202. The left telescopic rod 202 serves as a limit for the left buffer spring 203.

[0032] The right buffer assembly 3 includes a stop plate 301 and right telescopic rods 302 evenly spaced along the circumferential direction and mounted on the outer wall thereof. A right buffer spring 303 is sleeved on the outer side of the outer wall of the right telescopic rod 302. The right telescopic rod 302 serves as a limit for the right buffer spring 303.

[0033] A liquid inlet pipe 101 is provided at the center of the inner wall of one side of the housing 1, and a liquid outlet pipe 102 is provided at the center of the bottom of the housing 1;

[0034] An end cover 105 is installed inside the outer wall of the other side of the housing 1, and a card slot 1051 is provided on the top and bottom inner sides of the end cover 105;

[0035] The left telescopic rod 202 and the left buffer spring 203 are both located between the sealing ring 201 and the inner wall of one side of the housing 1. A sealing groove 2011 is provided on the inner wall of the sealing ring 201. The inner end of the filter element 103 is inserted into the sealing groove 2011.

[0036] The right telescopic rod 302 and the right buffer spring 303 are both located between the abutment plate 301 and the end cover 105. A damping column 304 is installed at the center of the end surface relative to the abutment plate 301 and the end cover 105. Under the elastic performance of the left buffer spring 203, the right buffer spring 303 and the damping column 304, a buffering and shock absorbing effect can be achieved.

[0037] When the above arrangement is in use, oil is introduced into the lubricating oil filter through the liquid inlet pipe 101, and the oil inside is filtered by the filter element 103 and discharged from the liquid outlet pipe 102. When the oil enters the filter element 103, it will generate a force to the right, thereby pushing the filter element 103 to move to the right and exerting pressure on the abutment plate 301. The abutment plate 301 is forced to move outward and squeeze the right telescopic rod 302, the right buffer spring 303 and the damping column 304. Under the elastic properties of the right buffer spring 303 and the damping column 304, they can play a role of buffering and shock absorption, and exert an opposite force on the filter element 103, so that the filter element 103 moves to the left, and pushes the sealing ring 201 to squeeze the left telescopic rod 202 and the left buffer spring 203. Under the elastic properties of the left buffer spring 203, it can play a buffering role, thereby reducing the buffering protection of the filter element 103, reducing the impact force and increasing the service life.

[0038] Among them Figure 1 , 5 As shown, the interior of the through slot 104 is provided with a mounting assembly 4, which includes a pressing block 401 and a linkage frame 402 movably connected to the inner wall thereof through a hinge, the inner side end of the linkage frame 402 is movably connected to the outer wall of the movable plate 403 through a hinge, and the hinged joints of the pressing block 401 and the linkage frame 402 and the hinged joints of the movable plate 403 and the linkage frame 402 can slide along both sides of the mounting surface;

[0039] The inner center position of the linkage frame 402 is movably connected to the limit rod 4021, and the two ends of the limit rod 4021 respectively penetrate the linkage frame 402 and are connected to the inner walls of the two sides of the through groove 104. The linkage frame 402 is located inside the through groove 104, and the limit rod 4021 plays a role of limiting the linkage frame 402, wherein the two ends of the linkage frame 402 are movably connected to the pressure block 401 and the movable plate 403 through hinges, and the linkage frame 402 slides to both sides at the hinges with the pressure block 401 and the movable plate 403 (the pressure block 401 and the movable plate 403 are both provided with sliding grooves on the opposite surfaces, and the sliding grooves are provided with sliders, and the ends of the linkage frame 402 are hinged to the sliders in the sliding grooves. When the angle of the linkage frame 402 changes, the slider moves in the sliding grooves), so that the linkage frame 402 works in a principle similar to the movement principle of scissors, and the pressure block 401 and the movable plate 403 are relatively moved by the force extension and contraction of the linkage frame 402, thereby achieving the purpose of moving the inner clamping plate 407;

[0040] The inner wall of the movable plate 403 is evenly spaced from front to back with connecting rods 405, and the other end of the connecting rod 405 passes through the through hole on one end surface of the fixed plate 404 and is connected to the clamping plate 407. The movable plate 403 and the clamping plate 407 are connected by the connecting rod 405 to play a role of connecting transmission, wherein the pressing block 401 is located on the outer side of the through slot 104, and the clamping plate 407 is located on the inner side of the through slot 104;

[0041] A return spring 406 is sleeved on the outer side of the outer wall of the connecting rod 405. The return spring 406 is located between the fixed plate 404 and the clamping plate 407. The outer wall of the fixed plate 404 is fixed on the inner wall of the through groove 104. The elastic performance of the return spring 406 drives the clamping plate 407 to move.

[0042] When the above arrangement is in use, during the process of disassembling, replacing and cleaning the internal filter element 103, first, the outer wall of the fixed plate 404 is fixed to the inner wall of the through groove 104, and the two ends of the limit rod 4021 are connected to the inner walls of the two sides of the through groove 104, and the pressing block 401 is pushed from the outside of the shell 1 to the inside, wherein the outer end and the inner end of the linkage frame 402 are movably connected to the pressing block 401 and the movable plate 403 through hinges, and at the same time, the hinged joints of the linkage frame 402, the pressing block 401 and the movable plate 403 can slide to both sides, and the inner center position of the linkage frame 402 is limited by the limit rod 4021, and at the same time, the two ends of the limit rod 4021 are movable. The ends are respectively fixed on the inner wall of the through groove 104 (the working principle of the linkage frame 402 is similar to the movement principle of scissors, which is a prior art and will not be described in detail here). The purpose of relative movement of the pressing block 401 and the movable plate 403 is achieved by changing the angle of the X-shaped linkage frame 402. Therefore, when the pressing block 401 is subjected to force, the upper and lower ends of the linkage frame 402 will gradually approach each other under the action of the hinge and the linkage frame 402. Since the position of the limit rod 4021 remains unchanged, the pressing block 401 and the movable plate 403 will approach each other, and the inner wall of the movable plate 403 is connected to the card plate 407 through the connecting rod 405, so when the movable plate 403 is When the pressure block 401 moves, the card plate 407 will be driven to move under the action of the connecting rod 405, wherein the return spring 406 is located between the card plate 407 and the fixed plate 404 fixed on the inner wall of the through groove 104, so when the card plate 407 moves, the return spring 406 will be squeezed. At this time, the return spring 406 is compressed, and the card plate 407 can be taken out from the card groove 1051, thereby canceling the limiting effect of the card plate 407 on the card groove 1051 on the end cover 105. Then the end cover 105 can be removed, and the internal filter element 103 can be disassembled, replaced and cleaned. In the same way during installation, the above operation is repeated to replace the filter element 103. After completion, the end cover 105 is inserted into the outer wall of the shell 1, and the clamping plate 407 is aligned with the clamping groove 1051, and then the force on the pressure block 401 is stopped. At this time, the clamping plate 407 is bounced into the clamping groove 1051 under the elastic performance of the return spring 406, so as to limit the end cover 105 and force the movable plate 403 to return to its original position. Since the position of the limiting rod 4021 in the through groove 104 remains unchanged, the linkage frame 402 will return to its original position and make the pressure block 401 extend out of the shell 1, which is convenient for the staff to quickly disassemble and assemble the end cover 105, and disassemble and assemble and replace the internal filter element 103, saving time and improving work efficiency.
