Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a filter with a stable structure. Background Art

[0002] A filter is an accessory that filters impurities or gases through filter paper. It generally refers to an automobile filter, which is an engine accessory. According to different filtering functions, it is divided into: oil filter, fuel filter (gasoline filter, diesel filter, oil-water separator, hydraulic filter), air filter, etc. The outside of the filter is generally a metal shell, and the shell is equipped with a filter element and other accessories. The shell is generally a thin layer of metal. During the production and use process, some collisions or the filter falling to the ground will cause the surface of the shell to collapse. Once the shell is damaged, it is very easy to squeeze the space inside the shell, thereby squeezing the filter element inside, causing the filter element to deform, which will greatly affect the filtering effect. Utility Model Content

[0003] The purpose of the utility model is to avoid the deficiencies of the prior art and provide a filter with a stable structure, thereby effectively solving the deficiencies in the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a filter with a stable structure, including an outer shell, in which a fixed spring, a filter element, a check valve and a threaded cover plate are arranged, a center tube is arranged at the center of the filter element, a bypass valve is arranged in the center tube, and a detachable inner support member is arranged on the inner wall of the outer shell, the inner support member is in a frame structure, and the inner support member is arranged in close contact with the inner wall of the outer shell.

[0005] Furthermore, the inner support member includes a plurality of support rings evenly distributed along the vertical direction, a plurality of reinforcing connecting rods are arranged between the support rings, and the reinforcing connecting rods are arranged in close contact with the inner wall of the outer shell.

[0006] Furthermore, a plurality of vertical retaining strips are circumferentially arranged on the inner wall of the outer shell, an escape notch is arranged on the outer side of each support ring to facilitate the passage of the retaining strip, and a slot is arranged on the retaining strip at a position corresponding to each layer of the support ring.

[0007] Furthermore, three retaining strips are arranged along the circumferential direction inside the outer shell, and three avoidance notches are arranged on each of the support rings.

[0008] Furthermore, the avoidance gap is arranged between two adjacent reinforcing connecting rods.

[0009] Furthermore, the support ring is fixed to the reinforcing connecting rod by welding.

[0010] Furthermore, the support ring and the reinforcing connecting rod are both made of stainless steel.

[0011] The above technical solution of the utility model has the following beneficial effects: the utility model can greatly increase the overall strength of the outer shell by arranging a detachable inner support member in the outer shell, so that the outer shell will not be deformed due to some bumps or falling on the ground, thereby ensuring the overall performance of the filter; furthermore, the inner support member can be disassembled and assembled, which is convenient for subsequent recycling and utilization, thereby helping to save costs.

[0016] In order to more clearly understand the above-mentioned purposes, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0017] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0018] like Figure 1-4 As shown, the filter of the present embodiment has a stable structure, comprising an outer shell 1, in which a fixing spring 2, a filter element 3, a check valve 4 and a threaded cover plate 5 are arranged, a center tube 6 is arranged at the center of the filter element 3, a bypass valve 7 is arranged in the center tube 6, and a detachable inner support member 8 is arranged on the inner wall of the outer shell 1, the inner support member 8 is in a frame structure, and the inner support member 8 is arranged in close contact with the inner wall of the outer shell 1.

[0019] The inner support member 8 includes a plurality of support rings 8 a evenly distributed along the vertical direction. A plurality of reinforcing connecting rods 8 b are arranged between the support rings 8 a . The reinforcing connecting rods 8 b are arranged in close contact with the inner wall of the outer shell 1 .

[0020] A plurality of vertical retaining strips 9 are circumferentially arranged on the inner wall of the outer shell 1, and an escape notch 8c is arranged on the outer side of each support ring 8a to facilitate the passage of the retaining strip 9, and a slot 9a is arranged on the retaining strip 9 at the position corresponding to each layer of support ring 8a.

[0021] By avoiding the notch 8 c, each support ring 8 a can move up and down along the retaining strip 9 , and the support ring 8 a can be clamped in the clamping groove 9 a of the retaining strip 9 .

[0022] Three retaining strips 9 are arranged along the circumferential direction of the outer shell 1, and three avoidance notches 8c are correspondingly arranged on each supporting ring 8a.

[0023] The avoidance notch 8c is arranged between two adjacent reinforcing connecting rods 8b, and the avoidance notch 8c avoids the position of the reinforcing connecting rod 8b, so as to facilitate the installation of the inner support member 8 inside the outer shell 1.

[0024] Preferably, the support ring 8a is fixed to the reinforcing connecting rod 8b by welding.

[0025] Preferably, the support ring 8a and the reinforcing connecting rod 8b are both made of stainless steel.

[0026] When the filter is replaced as a whole, the inner support member 8 can be taken out by rotating the inner support member 8 so that the avoidance notch 8c on the inner support member 8 is moved to the position corresponding to the slot 9a on the retaining strip 9.
