Description

Technical Field

[0001] The utility model relates to the field of filters, in particular to a structure for quickly disassembling and assembling a positioning plate. Background Art

[0002] The filter element positioning plate is an indispensable part of the filter. Its function is to fix the position of the filter element to prevent the filter element frame from deforming and affecting the filtering effect. Figure 6 When multiple filter elements are combined, the positioning plate must be removed before disassembling the filter elements. The connection between the positioning plate and each filter element is connected by bolts, which requires the removal of multiple bolts, making disassembly and assembly very troublesome. Some users remove the positioning plate for convenience and do not install it again, which is very harmful to the frame. For this reason, we designed a structure for quick disassembly and assembly of the positioning plate. Utility Model Content

[0003] In order to solve the technical problem of being able to quickly disassemble and assemble a positioning plate on a filter element, the utility model provides a structure for quickly disassembling and assembling a positioning plate.

[0004] The utility model is implemented by the following technical scheme: a structure for quick disassembly and assembly of a positioning plate, comprising a filter element positioning plate and a filter element, wherein the filter element is provided with multiple filter elements and they are designed in a circular array, a connecting protrusion is provided at the top of the filter element, a plurality of evenly distributed positioning sockets are provided on the upper end surface of the filter element positioning plate, and the plurality of positioning sockets are arranged in a circular array, a positioning protrusion is formed at the center of the filter element positioning plate protruding upward, a positioning slot is provided at the bottom end of the positioning protrusion, a connecting screw hole is provided at the top end of the positioning protrusion, the connecting screw hole is communicated with the positioning slot, the multiple connecting protrusions of the outer circle and the inner circle are plugged into the positioning sockets, and the connecting protrusion at the center is plugged into the positioning slot, and the connecting protrusion and the positioning protrusion are connected by connecting bolts.

[0005] As a further improvement of the above scheme, the shape of the positioning socket matches the shape of the connecting protrusion and is a regular hexagonal structure, and the size of the positioning socket matches the size of the connecting protrusion. The positioning socket can be sleeved on the outside of the connecting protrusion, thereby facilitating its rapid positioning and fixing, and making it less likely to shake, and its position can be fixed, thereby preventing deformation of the filter element skeleton.

[0006] As a further improvement of the above scheme, the positioning socket is in the shape of a circular structure, and the inner wall of the positioning socket is in contact with the outer edge of the connecting protrusion. The positioning socket on the filter element positioning plate is stamped. The circular positioning socket is convenient for quick processing and the processing method is simple. After the positioning socket is sleeved on the outside of the connecting protrusion and contacts its edge, it can be positioned and fixed, thereby preventing the filter element skeleton from deforming.

[0007] As a further improvement of the above scheme, a plurality of circulation openings distributed in a circular pattern are provided on the upper surface of the filter element positioning plate, and the cross-section of the circulation openings is a cross-shaped structure. The circulation openings are stamped and formed, and the design of the circulation openings reduces the weight of the filter element positioning plate and connects the upper and lower parts, thereby facilitating the flow of the fluid inside the filter. The cross-shaped structure maximizes its area while having a certain distance between the openings and the positioning sockets, thereby ensuring the overall strength of the filter element positioning plate.

[0008] As a further improvement of the above scheme, the positioning slot is designed to be a cylindrical structure, the depth of the positioning slot is consistent with the height of the connecting protrusion, and the inner diameter of the positioning slot is larger than the width of the connecting protrusion. The positioning slot with a cylindrical structure facilitates the rapid insertion of the connecting protrusion into the positioning slot, and the positioning slot with a cylindrical structure is also convenient for processing by a drilling machine or a milling machine. After the connecting protrusion in the middle position is inserted into the positioning slot, the top of the connecting protrusion can contact the top of the positioning slot, so that it can be quickly fixed, and the fixing effect is good.

[0009] As a further improvement of the above solution, the lower end surface of the filter element positioning plate is in close contact with the upper surface of the filter element, which improves the firmness of the connection between the filter element positioning plate and the filter element and improves the fixing effect.

[0010] As a further improvement of the above scheme, the number and position of the positioning sockets on the filter element positioning plate correspond one-to-one with the number and position of multiple filter elements arranged in a ring shape, so that multiple filter elements can be fixed on the filter element positioning plate, thereby quickly and accurately positioning and fixing multiple filter elements.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. The utility model changes the structure of the original filter element positioning plate, and arranges a positioning socket and a positioning slot for sleeved filter elements on the top of the filter element positioning plate, so that the filter element positioning plate can be quickly placed on the filter element, and then all filter elements can be positioned and fixed by only fixing the filter element at the center with connecting bolts, so that the position of the filter element can be quickly fixed to prevent the deformation of the filter element frame;

[0013] 2. The overall structure of the filter element positioning plate is simple and easy to process. It can quickly position and fix multiple filter elements and is also easy to disassemble quickly. The positioning socket on the filter element positioning plate is used instead of bolt fixing, making installation and disassembly more convenient and avoiding damage to the positioning thread above the filter element due to frequent use.

[0022] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0023] Example:

[0024] Please combine Figure 1-Figure 5, a positioning plate quick disassembly and assembly structure of the present embodiment comprises a filter element positioning plate 2 and a filter element 1, the filter element 1 is provided with multiple and they are designed in a circumferential array, a connecting protrusion 11 is provided at the top of the filter element 1, a plurality of evenly distributed positioning sockets 23 are provided on the upper end surface of the filter element positioning plate 2, and the plurality of positioning sockets 23 are arranged in a circumferential array, a positioning protrusion 21 is formed at the center of the filter element positioning plate 2 protruding upward, a positioning slot 4 is provided at the bottom end of the positioning protrusion 21, a connecting screw hole 211 is provided at the top end of the positioning protrusion 21, and the connecting screw hole 211 is connected to the positioning slot 4, a plurality of connecting protrusions 11 on the outer circle and the inner circle are plugged into the positioning sockets 23, and the connecting protrusion 11 at the center is plugged into the positioning slot 4, and the connecting protrusion 11 and the positioning protrusion 21 are connected by a connecting bolt 3.

[0025] The shape of the positioning socket 23 matches the shape of the connecting protrusion 11 and is a regular hexagonal structure, and the size of the positioning socket 23 matches the size of the connecting protrusion 11. The positioning socket 23 can be sleeved on the outside of the connecting protrusion 11, thereby facilitating its rapid positioning and fixing, and making it less likely to shake, and its position can be fixed, thereby preventing deformation of the filter element skeleton.

[0026] The positioning socket 23 is in the shape of a circular structure, and the inner wall of the positioning socket 23 contacts the outer edge of the connecting protrusion 11. The positioning socket 23 on the filter element positioning plate 2 is stamped. The circular positioning socket 23 is convenient for quick processing and the processing method is simple. After the positioning socket 23 is sleeved on the outside of the connecting protrusion 11 and contacts its edge, it can be positioned and fixed, thereby preventing the filter element frame from deforming.

[0027] A plurality of circulation openings 22 distributed in a circular pattern are provided on the upper surface of the filter element positioning plate 2, and the cross-section of the circulation openings 22 is a cross-shaped structure. The circulation openings 22 are stamped and formed, and the design of the circulation openings 22 reduces the weight of the filter element positioning plate 2 and connects the upper and lower parts, thereby facilitating the flow of the fluid inside the filter. The cross-shaped structure maximizes its area while having a certain distance between it and the opened positioning sockets 23, thereby ensuring the overall strength of the filter element positioning plate 2.

[0028] The positioning slot 4 is designed with a cylindrical structure. The depth of the positioning slot 4 is consistent with the height of the connecting protrusion 11, and the inner diameter of the positioning slot 4 is larger than the width of the connecting protrusion 11. The cylindrical structure of the positioning slot 4 is convenient for the connecting protrusion 11 to be quickly inserted into the positioning slot 4, and the cylindrical structure of the positioning slot 4 is also convenient for processing by a drilling machine or a milling machine. After the connecting protrusion 11 in the middle position is inserted into the interior of the positioning slot 4, the top of the connecting protrusion 11 can contact the top of the positioning slot 4, so that it can be quickly fixed, and the fixing effect is good.

[0029] The lower end surface of the filter element positioning plate 2 is in close contact with the upper surface of the filter element 1, which improves the firmness of the connection between the filter element positioning plate 2 and the filter element 1 and improves the fixing effect.

[0030] The number and position of the positioning sockets 23 on the filter element positioning plate 2 correspond one-to-one to the number and position of multiple filter elements 1 arranged in a ring shape, which facilitates the fixing of multiple filter elements 1 on the filter element positioning plate 2, thereby enabling the multiple filter elements 1 to be positioned and fixed quickly and accurately.

[0031] The implementation principle of the structure of a positioning plate for quick disassembly and assembly in the embodiment of the present application is as follows: before the upper part of the filter element 1 is fixed, the lower part thereof will be threadedly fixed to the plurality of filter elements 1 by the fixing plate. When the plurality of filter elements 1 are installed and positioned, the positioning sockets 23 and the positioning slots 4 on the filter element positioning plate 2 are aligned with the connecting protrusions 11 of the filter element 1 and are sleeved on the connecting protrusions 11. At this time, the lower end surface of the filter element positioning plate 2 is in contact with the upper surface of the filter element 1, and the top of the connecting protrusion 11 can be in contact with the top of the positioning slot 4. Then, the connecting bolts 3 are screwed into the connecting screw holes 211 and the screw holes above the connecting protrusions 11 to fix the two. When disassembling, it is only necessary to remove the connecting bolts 3 in the middle position, and then the filter element positioning plate 2 can be pulled out upward as a whole, without the need to remove other bolts additionally, thereby improving convenience.

[0032] By changing the structure of the original filter element positioning plate 2, a positioning socket 23 and a positioning slot 4 for sleeve-fitting the filter element 1 are provided above the filter element positioning plate 2, so that the filter element positioning plate 2 can be quickly placed above the filter element 1, and then all the filter elements 1 can be positioned and fixed by only fixing the filter element 1 at the center with the connecting bolts 3, so that the position of the filter element 1 can be quickly fixed to prevent the filter element frame from being deformed;

[0033] The filter element positioning plate 2 has a simple overall structure and is easy to process. It can quickly position and fix multiple filter elements 1 and is also easy to quickly disassemble. The positioning socket 23 on the filter element positioning plate 2 replaces the bolt fixation, making installation and disassembly more convenient and avoiding damage to the positioning thread above the filter element 1 due to frequent use.

[0034] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
