Description

Technical Field

[0001] The utility model belongs to the technical field of filtering equipment, and in particular relates to a filter installation assembly. Background Art

[0002] Filters are widely used in various mechanical equipment. They are mainly used to filter impurities in oil, air or other fluids to ensure the normal operation and service life of the equipment. In various mechanical equipment, filters usually need to be fixed in a certain position to ensure that they can effectively filter the fluid during operation.

[0003] However, the installation and fixation of the filter is a key issue, especially when vibrations are often encountered during the operation of the equipment. These vibrations may cause the filter to loosen or even separate from its base, thus affecting the filtering effect and the normal operation of the equipment.

[0004] In the prior art, filters are usually installed by threaded connection, snap connection or other mechanical connection methods. Although these connection methods can ensure the fixation of the filter to a certain extent, there is still the problem of looseness between the filter and the base in a long-term vibration environment. In addition, the existing filter installation structure is relatively complicated in operation, and the installation and removal process is cumbersome, which affects the maintenance efficiency. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a filter installation assembly, which can be implemented and can effectively solve the problems existing in the prior art such as insufficient seismic performance, complicated installation operation and insufficient sealing.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A filter installation assembly comprises a base, the bottom of the base is connected to an oil circuit seat, the top of the base is connected to a filter body, the top of the filter body is buckled with a positioning cover, and a pulling component is arranged between the base and the positioning cover;

[0008] The outer side of the base is provided with first hanging ears at equal intervals around the central axis thereof, and the outer side of the positioning cover is provided with second hanging ears corresponding to the first hanging ears;

[0009] Two ends of the pulling assembly are respectively connected to the second hanging ear and the first hanging ear.

[0010] Furthermore, the pulling assembly includes a rubber segment, both ends of the rubber segment are fixedly connected to a pull rod, and a positioning column is fixedly connected to the side surface of one end of the pull rod.

[0011] Furthermore, the shapes of the first hanging ear and the second hanging ear are both set to be L-shaped, and the sides of the first hanging ear and the second hanging ear are respectively provided with a first through groove and a second through groove;

[0012] The first through slot and the second through slot are both in a gourd shape;

[0013] One end of the positioning column is fixedly connected with a baffle.

[0014] Furthermore, a tightening head is arranged on the top of the filter body, and a locking groove matched with the tightening head is opened on the bottom of the positioning cover.

[0015] Furthermore, a sealing groove is provided on the top of the base.

[0016] Furthermore, an oil inlet groove is provided at the top of the base, an oil return pipe is fixedly connected to the bottom of the oil inlet groove, and a through groove is provided through the bottom of the oil inlet groove.

[0017] Furthermore, one end of the oil circuit seat is fixedly connected with a connecting plate.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] By arranging a positioning cover and a pulling assembly between the base and the filter body, the filter is made simpler and more convenient during installation; after the filter body is screwed onto the oil return pipe and the sealing ring is placed in the sealing groove, the connection between the filter body and the base is made more secure through the engagement of the positioning cover and the cooperation of the pulling assembly, thereby avoiding the loosening or separation of the filter in a vibrating environment and improving the operating reliability and filtering effect of the equipment.

[0020] By arranging first hanging ears at equal intervals on the outside of the base and corresponding second hanging ears on the outside of the positioning cover, and then connecting the first hanging ears and the second hanging ears at both ends of the pulling assembly respectively, a stable connection between the filter and the base is achieved; this structural design is simple and effective, and can provide sufficient stability when installing the filter, avoiding loosening problems caused by vibration.

[0021] The pulling assembly includes a rubber segment and a pull rod fixedly connected to both ends of the rubber segment. A positioning column is fixedly connected to the side of one end of the pull rod. The positioning column is inserted into the first through groove and the second through groove. The limiting effect of the baffle plate is used to ensure that the positioning column remains stable in a vibration environment. This design effectively solves the problem of loosening of the filter during equipment vibration through reasonable structural configuration, ensuring a stable connection between the filter and the base.

[0022] The first hanging ear and the second hanging ear are both arranged in an L shape, and the first and second gourd-shaped through grooves are respectively provided on the sides. Through the cooperation of the positioning column and the baffle plate, a stable connection between the filter and the base is achieved. This design ensures the stability of the connection while being simple and convenient to operate, thereby improving the installation and maintenance efficiency of the filter.

[0023] The tightening head on the top of the filter body is matched with the locking groove at the bottom of the positioning cover. Through the locking of the locking groove, the filter body is more stable under the action of the positioning cover, and the connection firmness between the filter and the base is further enhanced. This design not only simplifies the installation process, but also effectively improves the stability of the filter in a vibration environment.

[0024] A sealing groove is set on the top of the base, and a sealing ring is placed in the sealing groove to ensure the sealing between the filter and the base and avoid fluid leakage problems. Through this sealing structure design, the filter can maintain good sealing performance during operation, improving the operating reliability and filtering effect of the equipment.
