Description

Technical Field

[0001] This utility model relates to the field of filter element technology, and in particular to a filter element clamping device. Background Technology

[0002] Existing oil mist filters typically consist of a bracket, a filter element, and a sealing plate. The bracket has a placement groove, and the filter element is installed within the bracket and held in place by the sealing plate, which compresses the filter element. This compression usually employs a detachable connection, typically using bolts or cams. Bolt connections involve bolts passing through the sealing plate and connecting it to the bracket for assembly and disassembly. However, over time, oil deposits can accumulate at the bolts, making disassembly difficult. For example, Chinese patent CN 220082111 U discloses a cam-type filter element lifting and sealing structure. This structure uses a cam mechanism where the front and rear sides of the rectangular frame are symmetrically connected to rotating shafts. Eccentric cams are symmetrically positioned at the front and rear ends of the rotating shafts, and a handle is located at the front end. While this cam connection allows the handle to rotate relative to the rectangular frame, oil deposits can still cause the handle to stick to the frame, preventing rotation.

[0003] In summary, it can be seen that the cam structure has the advantage of simple operation, but how to arrange the cam structure to facilitate the clamping of the sealing plate while preventing the accumulation of oil stains in the cam clamping structure is a technical problem that needs to be solved. Utility Model Content

[0004] The present invention proposes a filter element clamping device that, through optimized structural layout, ensures the sealing plate is clamped while preventing oil stains from accumulating in the cam clamping structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a filter element clamping device, comprising a bracket and a sealing plate, the sealing plate being placed in a slot in the bracket, and further comprising a cam and a rotating shaft, the cam being mounted through the rotating shaft and located beside the slot; further comprising several support members, the support members being arranged sequentially along the edge of the bracket, the rotating shaft being mounted on the support members and rotatingly engaging with the support members; the cam can rotate relative to the support members through the rotating shaft and press the sealing plate tightly, and in the non-pressing state, there is a hollow portion between the cam and the bracket;

[0006] This prevents oil and grease from accumulating under the cam and between the bracket.

[0007] Preferably, the bracket is a rectangular structure composed of a transverse connecting part and a longitudinal connecting part, wherein a plurality of slots are provided between the transverse connecting part and the longitudinal connecting part;

[0008] This design allows multiple oil mist filters to be installed using a single bracket, saving on consumables.

[0009] Preferably, there are multiple support members, which are evenly arranged on the transverse connecting part.

[0010] Preferably, the protrusion of the cam abuts against the sealing plate and may be located in the gap between the sealing plate and the slot;

[0011] To further prevent oil from overflowing from the gaps, it can effectively prevent the formation of oil stains. Even if oil stains do form, they will only be in the gaps and will not excessively contaminate parts such as cams, shafts, and supports.

[0012] Preferably, it also includes a handle, which is detachably connected to the end of the rotating shaft.

[0013] Preferably, the bracket, cam, rotating shaft, and support are all made of stainless steel;

[0014] It makes cleaning oil stains easy.

[0015] Preferably, the cam is detachably connected to the rotating shaft;

[0016] It facilitates the adjustment, replacement, and maintenance of the cam size.

[0017] Preferably, the detachable connection is an interference fit between the cam and the rotating shaft through a through hole.

[0018] Preferably, the cam is welded to the rotating shaft.

[0019] Compared with the prior art, the present invention provides a filter element clamping device with the following advantages: the cam rotates relative to the support through the rotating shaft and presses the sealing plate. In the non-clamping state, there is a hollow part between the cam and the bracket, which prevents oil stains from accumulating under the cam and between the bracket. On the other hand, it also realizes the clamping and loosening of the filter element, solving the problem of quick disassembly and installation. At the same time, the cam and the filter element form a line contact, making the filter element installation easier. Attached Figure Description

[0023] The technical solutions of the present utility model will now be described with reference to the accompanying drawings in the embodiments of the present utility model:

[0024] like Figure 1 , 2 As shown, a filter element clamping device includes a bracket 1 and a sealing plate 2. The sealing plate 2 is placed in a slot 3 within the bracket 1. The bracket 1 is a rectangular structure composed of a transverse connecting part 7 and a longitudinal connecting part 8, wherein several slots 3 are provided between the transverse connecting part 7 and the longitudinal connecting part 8. This design allows multiple oil mist filters to be installed using a single bracket, saving consumables. The filter element clamping device also includes a cam 4 and a rotating shaft 5. The cam 4 is mounted through the rotating shaft 5 and located next to the slots 3. The cam 4 and the rotating shaft 5 can be detachably connected, facilitating cam size adjustment, replacement, and maintenance. The detachable connection means that the cam 4 is press-fitted to the rotating shaft 5 through a through hole. Alternatively, the cam 4 and the rotating shaft 5 can be welded together, improving the stability between the cam 4 and the rotating shaft 5. The filter element clamping device also includes several support members 6, each with a limiting groove. A rotating shaft 5 is positioned within the limiting groove. The support members 6 are arranged sequentially along the edge of the bracket 1. Multiple support members 6 are evenly distributed on the transverse connecting part 7. The arrangement of the support members and the design of the limiting groove improve the stability of the rotating shaft. The end of the rotating shaft 5 is detachably connected to a handle 9 via bolts. The handle 9 is a swing arm that can be manually rotated, saving effort and improving efficiency. The rotating shaft 5 is mounted on the support members 6 and rotates in conjunction with them. The cam 4 can rotate relative to the support members 6 via the rotating shaft 5, pressing the sealing plate 2. In the non-pressurized state, there is a hollow section between the cam 4 and the bracket 1, preventing oil buildup between the cam 4 and the bracket 1. When the protrusion of cam 4 is directly above, the open portion can be at least 1 cm wide, and this is the normal state when not compressed, keeping the protrusion at the top. In the compressed state, the protrusion presses the sealing plate 2, but other parts remain open, forming a very small surface contact between the protrusion and the sealing plate 2. Therefore, oil will only accumulate in this surface contact area and will not contaminate other parts of the cam. The protrusion of cam 4 abuts against the sealing plate 2 and can be located in the gap between the sealing plate 2 and the slot 3 to further prevent oil from overflowing from the gap, effectively preventing oil buildup. Even if oil does form, it will only be in this gap and will not excessively contaminate cam 4, rotating shaft 5, and support 6. The bracket 1, cam 4, rotating shaft 5, and support 6 are all made of stainless steel for easy cleaning of oil.

[0025] When in use, turn the handle 9. The handle 9 drives the rotating shaft 5 and the cam 4 to rotate synchronously and press the sealing plate 2 tightly. This not only prevents oil stains from accumulating under the cam 4 and between the bracket 1, but also solves the problem of quick disassembly and installation of the filter element. At the same time, the cam 4 forms a line contact with the filter element, making the filter element installation easier.

[0026] The above embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
