Description

Technical Field

[0001] The utility model relates to the technical field of replacement of oil pump filters, and specifically relates to an oil pump filter replacement assembly. Background Technique

[0002] The oil pump is one of the very important components in the hydraulic system or fuel system. Its function is to send liquid or fuel into the high-pressure system to meet the usage requirements of the system. The oil pump filter is the most important component to ensure the normal operation of the oil pump. It can effectively filter impurities and particulate matter in the hydraulic system or fuel system and protect the normal operation of the system. The quality of the oil pump filter directly affects the service life and maintenance cost of the hydraulic system or fuel system. Therefore, it is very important to correctly install and regularly clean and maintain the oil pump filter.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] The present utility model provides as Figures 1 to 6An oil pump filter replacement assembly shown includes a base 1 and an oil pump tank 2. Connecting pipes 3 are connected to both sides of the base 1. The oil pump tank 2 is installed on the top of the base 1. A fixing part 4 is clamped at the connection between the oil pump tank 2 and the base 1. A disassembly and assembly mechanism 5 is arranged on one side of the base 1. The disassembly and assembly mechanism 5 is clamped with the fixing part 4. A filtering component 6 is arranged in the inner cavity of the oil pump tank 2.

[0025] Through the cooperation between the arranged disassembly and assembly mechanism 5 and the fixing part 4, the oil pump tank 2 and the base 1 can be installed and disassembled, so as to facilitate the replacement and cleaning of the filtering component 6 in the oil pump tank 2, saving the time for the staff to disassemble and assemble, which is convenient and fast.

[0026] The fixing part 4 includes a positioning ring 41. One end of the positioning ring 41 is hinged through a hinge, and a connecting block 42 used in cooperation with the disassembly and assembly mechanism 5 is fixedly connected to the end opposite to the positioning ring 41. The inner side wall of the positioning ring 41 is clamped at the connection between the oil pump tank 2 and the base 1.

[0027] The arranged hinge can provide a movable effect for the positioning ring 41, and then the positioning ring 41 is clamped at the connection between the oil pump tank 2 and the base 1, so as to provide a fixing effect on the connection between the oil pump tank 2 and the base 1.

[0028] The disassembly and assembly mechanism 5 includes a support frame 51. One end of the support frame 51 is fixedly connected to the side wall of the base 1. A movable sleeve 52 is embedded on the surface of the support frame 51. A pull rod 53 is movably connected in the inner cavity of the movable sleeve 52. One end of the pull rod 53 is fixedly connected with a limit seat 54. The bottom of the limit seat 54 is slidably connected with the support frame 51. The limit seat 54 is provided with a cavity. The connecting block 42 fixed on the positioning ring 41 is clamped in the cavity of the limit seat 54. A first spring 55 is sleeved on the surface of the pull rod 53. The two ends of the first spring 55 are respectively fixedly connected between the support frame 51 and the limit seat 54. The other end of the pull rod 53 is fixedly connected with a pull ring 56.

[0029] Through the cooperation between the arranged pull rod 53 and the limit seat 54, it can be clamped with the connecting block 42 fixed on the positioning ring 41. Thus, the staff only needs to adjust the position of the pull rod 53 outward, and the limit seat 54 can be separated from the connecting block 42;

[0030] Similarly, through the elastic compression provided by the first spring 55, the limit seat 54 can be driven to limit and clamp the connecting block 42, so as to fix the opening and closing of the positioning ring 41. It not only facilitates the disassembly and assembly between the oil pump tank 2 and the base 1, but also can replace the original bolt fixing method to replace the filter screen 61 in the oil pump tank 2, preventing the phenomenon of thread slipping.

[0031] A chute 7 is provided at the position where the support frame 51 is in contact with the bottom of the limit seat 54. A slider 8 which is in limit sliding connection with the chute 7 is arranged at the bottom of the limit seat 54. Through the cooperation of the provided chute 7 and the slider 8, the position of the movement of the limit seat 54 can be limited, and the stability of the movement of the limit seat 54 is improved.

[0032] Positioning grooves 9 are provided on the opposite sides in the cavity of the limit seat 54. Positioning blocks 10 are fixedly connected to the surface of the connecting block 42 at the positions corresponding to the positioning grooves 9. Through the cooperation of the provided positioning grooves 9 and the positioning blocks 10, the positioning effect of the connecting block 42 in the limit seat 54 can be enhanced.

[0033] Two clamping grooves 11 are provided on the inner side wall of the positioning ring 41. Clamping blocks 12 are fixedly connected to the outer walls at the connection positions of the oil pump tank 2 and the base 1. The clamping blocks 12 are clamped in the clamping grooves 11. Through the cooperation of the provided positioning grooves 9 and the positioning blocks 10, the base 1 and the oil pump tank 2 can be clamped and fixed by the positioning ring 41, and the stability and sealing effect between the base 1 and the oil pump tank 2 are enhanced.

[0034] The filtering assembly 6 includes a filter screen 61 and a second spring 62. The filter screen 61 is inserted into the oil pump tank 2. One end of the second spring 62 is in contact with the top of the inner cavity of the oil pump tank 2, and the other end of the second spring 62 is in contact with the filter screen 61. The provided second spring 62 can provide elastic force to the filter screen 61, thereby preventing the filter screen 61 from shaking in the oil pump tank 2.

[0035] Limit grooves 13 are provided around the bottom of the filter screen 61. Limit posts 14 are fixedly connected to the positions on the base 1 connected to the filter screen 61. The limit posts 14 are inserted into the limit grooves 13. Through the cooperation of the provided positioning grooves 9 and the limit posts 14, the fixing effect of the installation of the filter screen 61 is further strengthened.

[0036] During specific use, when the filter screen 61 needs to be replaced, first, the staff pulls the pull rod 53 to extend outwards through the pull ring 56. Then the pull rod 53 drives the separation between the limit seat 54 and the connecting block 42, and compresses the first spring 55. Subsequently, the positioning ring 41 is removed from the oil pump tank 2 and the base 1. Then the oil pump tank 2 is taken off, and the filter screen 61 can be replaced and cleaned. Similarly, the replaced filter screen 61 is installed on the base 1 again. Then the oil pump tank 2 is sleeved outside the filter screen 61. Then the oil pump tank 2 and the base 1 are clamped and fixed by the positioning ring 41. Subsequently, the pulling force on the pull rod 53 is released. The elastic rebound provided by the first spring 55 drives the limit seat 54 to move towards the connecting block 42 to clamp and fix the connecting block 42, replacing the original bolt fixing operation. Thus, the fixing member 4 can be quickly separated from the base 1 and the oil pump tank 2, and the filter screen 61 in the oil pump tank 2 can be replaced and cleaned, improving the efficiency of replacing the filter screen 61 in the oil pump.

[0037] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
