Description

Technical Field

[0001] This utility model relates to the field of hydraulic filter technology, specifically to a novel filter cover. Background Technology

[0002] Hydraulic filters are filtration devices used to filter hydraulic oil and play a vital role in hydraulic systems. Existing hydraulic filters consist of components such as a housing, filter element, filter cover, and sealing rings.

[0003] In the existing technology, the filter cover of the filter needs to meet the functions of disassembly, sealing and venting for normal use; this makes the overall wall thickness of the filter cover thicker, the weight heavier, and the amount of material required, resulting in higher cost of the filter cover. Summary of the Invention

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a new type of filter cover that is simple in structure and lightweight.

[0005] The technical solution adopted in this utility model is as follows:

[0006] A novel filter cover includes a cover body and detachable bosses. The cover body consists of a top plate and a cylindrical peripheral wall hanging down from the periphery of the top plate. A boss is provided in the middle of the outer surface of the top plate. The number of detachable bosses is at least two and they are evenly distributed around the outer surface of the top plate. The two detachable bosses are connected to each other by an outer reinforcing rib. An exhaust hole is provided on the top plate. An installation thread is provided in the lower part of the cylindrical peripheral wall. Multiple sealing grooves are provided in the cylindrical peripheral wall and on the top surface of the installation thread. A positioning boss and multiple inner reinforcing ribs are provided on the inner surface of the top plate.

[0007] Preferably, the top plate is hemispherical.

[0008] Preferably, the number of detachable bosses is four, and their distribution is symmetrical about the center of the top plate.

[0009] Preferably, the four detachable bosses are connected to each other by external reinforcing ribs on opposite sides facing the center of the top plate.

[0010] Preferably, the shape of the detachable boss is cylindrical, square, or other shapes.

[0011] Preferably, the number of sealing grooves is one or more.

[0012] Preferably, the inner surface of the top plate is provided with four inner reinforcing ribs, all of which are in the shape of a "V"; the four inner reinforcing ribs are evenly distributed on the inner surface of the top plate; the openings of the four inner reinforcing ribs all face outwards; the lower ends of the four inner reinforcing ribs face inwards to form a cross-shaped opening.

[0013] Preferably, the number of positioning bosses is one or more.

[0014] Preferably, there are four positioning bosses, which are distributed between adjacent inner reinforcing ribs.

[0015] The advantages of this utility model are: the utility model has a simple structure, ingenious design, and convenient operation. While ensuring strength, the simplified inner and outer reinforcing ribs are set on the upper and lower surfaces of the top plate of the filter cover body, eliminating the need for a thicker top plate for support, thus reducing its weight and saving manufacturing costs.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figure 1-4 As shown, the present invention discloses a novel filter cover comprising a filter cover body 1 and detachable protrusions 2. The filter cover body 1 is composed of a hemispherical top plate 9 and a cylindrical peripheral wall 10 extending from the periphery of the top plate 9. A protrusion 11 is provided in the middle of the outer surface of the top plate 9. The number of detachable protrusions 2 is at least two and they are evenly distributed around the outer circumference of the top plate 9. The opposing faces of the two detachable protrusions 2 are connected to the protrusions 11 by external reinforcing ribs 8. The shape of the detachable protrusions 2 can be cylindrical, square, or other shapes, which are selected according to the actual use of the filter. Furthermore, the number of detachable protrusions 2 is set to four, and their distribution is symmetrical about the center of the top plate 9. The opposing faces of the four detachable protrusions 2 facing the center of the top plate 9 are connected to the protrusions 11 by external reinforcing ribs 8 to ensure the strength of the detachable protrusions 2.

[0023] The top plate 9 of this utility model is provided with an exhaust hole 4 for venting the filter. The specific location of the exhaust hole 4 can be located at the center of the outer surface of the top plate 9 (i.e., the exhaust hole 4 is provided on the boss 2), or it can be set according to the actual situation of the filter.

[0024] The lower part of the cylindrical peripheral wall 10 in this utility model is provided with an installation thread 3 for fixing and locking with the installation port of the filter body; one or more sealing grooves 5 are provided inside the cylindrical peripheral wall 10 and on the top surface of the installation thread 3 for sealing with the installation port of the filter body.

[0025] The inner surface of the top plate 9 in this utility model is provided with positioning bosses 6 and multiple inner reinforcing ribs 7. Among them, the inner surface of the top plate 9 is provided with four inner reinforcing ribs 7, all of which are in the shape of "V"; the four inner reinforcing ribs 7 are evenly distributed on the inner surface of the top plate 9; the openings of the four inner reinforcing ribs 7 all face outward; the lower ends of the four inner reinforcing ribs 7 face inward to form a cross-shaped opening.

[0026] In this invention, there are one or more positioning protrusions 6, used to limit the position of the filter element and ensure that the filter element does not tilt. Furthermore, four positioning protrusions 6 are provided, with each of the four positioning protrusions 6 distributed between adjacent inner reinforcing ribs 7.

[0027] The usage process of this utility model is as follows:

[0028] During use, the staff installs the number and position of each component according to the specific situation of the filter. First, four cylindrical mounting bosses 2 are evenly distributed around the outer circumference of the top plate 9. The four mounting bosses 2 facing the center of the top plate 9 are connected to the bosses 11 by the outer reinforcing ribs 8 to ensure the strength of the mounting bosses 2. Next, two sealing grooves 5 are set inside the cylindrical peripheral wall 10 and on the top surface of the mounting thread 3. Then, four positioning bosses 6 and four inner reinforcing ribs 7 are set on the inner surface of the top plate 9. The four inner reinforcing ribs 7 are evenly distributed on the inner surface of the top plate 9. The openings of the four inner reinforcing ribs 7 all face outward. The lower ends of the four inner reinforcing ribs 7 form a cross-shaped opening. The four positioning bosses 6 are distributed between adjacent inner reinforcing ribs 7.

[0029] The installed filter cover body 1 is fixed and locked to the installation port of the filter barrel through the installation thread 3.

[0030] Other undescribed parts of this utility model are the same as those in the prior art.
