Technical Field

[0001] This utility model relates to the field of primary filter technology, specifically a universal primary filter fixing base. Background Technology

[0002] The pre-filter is the most basic filtration device in an air filtration system. It belongs to the pre-filtration level and is mainly used to intercept larger particles of pollutants in the air. It is the first line of defense for air purification. The fixed base is the structure used for storing or transporting the pre-filter to ensure its structural stability.

[0003] Currently, the fixed base for primary filters places the primary filters to be stored or transported inside the tank and limits their position. In order to ensure the safety of the placed primary filters, an isolation cover is installed to protect them. However, when retrieving the primary filters located on the outermost sides, the entire isolation cover needs to be moved outward, which is time-consuming and laborious, affecting the actual use effect. Therefore, there is a need to provide a fixed base that can solve the above-mentioned drawbacks and improve the effect. Utility Model Content

[0004] The purpose of this utility model is to provide a universal primary filter mounting base to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution:

[0005] This utility model is a universal primary filter fixing base, comprising:

[0006] A base, wherein the upper end of the base is symmetrically provided with isolation covers;

[0007] The positioning structure includes guide frames symmetrically threaded to the front and rear ends of the base. A guide block is slidably provided inside the guide frame, and a shaft is rotatably connected to the outer side of the guide block. A connecting column is sleeved in the middle of the shaft, and a movable plate is fixed at one end of the connecting column. The side of the movable plate abuts against the inner wall of the isolation cover.

[0008] Furthermore, a threaded hole is provided through one end of the movable plate, and a plug is provided inside the threaded hole and protrudes outward.

[0009] Furthermore, it also includes a fixing structure, which includes fixing grooves equidistantly formed at the middle of the upper end of the base.

[0010] Furthermore, movable tubes are fixed on opposite sides of the inner wall of the fixed groove, and movable columns are connected inside the movable tubes via movable springs.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figure 1-5 As shown, this utility model is a universal primary filter fixing base, comprising:

[0026] The base 11 has symmetrical isolation covers 14 at its upper end;

[0027] The isolation enclosure 14 provides external isolation protection for the pre-filter inside.

[0028] The upper part of both sides of the base 11 is symmetrically provided with sliding grooves 12, and sliding blocks 13 are symmetrically slidably provided in the sliding grooves 12. The upper end of the sliding block 13 is fixed to the bottom end of the isolation cover 14.

[0029] The sliding block 13 is installed and fixed to the isolation cover 14, and the isolation cover 14 can be moved to multiple positions by sliding in the sliding groove 12.

[0030] The inner side of the sliding groove 12 is provided with a groove 15, and the inner side of the sliding block 13 is provided with a rectangular protrusion 16, which extends into the groove 15, and the rectangular protrusion 16 abuts against the inner wall of the groove 15.

[0031] The rectangular protrusion 16 slides within the groove 15, satisfying the positional movement of the isolation cover 14. At the same time, the mutual contact between the two can limit the sliding isolation cover 14, preventing it from falling off the base 11 and being damaged, thus helping to save costs and reduce costs.

[0032] The positioning structure includes a guide frame 21 symmetrically threaded to the front and rear ends of the base 11. A guide block 22 is slidably provided inside the guide frame 21, and a shaft 23 is rotatably connected to the outer side of the guide block 22. A connecting column 24 is sleeved in the middle of the shaft 23, and a movable plate 25 is fixed at one end of the connecting column 24. The side of the movable plate 25 abuts against the inner wall of the isolation cover 14.

[0033] The guide block 22 is fixed to the movable plate 25 via the shaft 23 and the connecting column 24. By sliding within the guide frame 21, the vertical position of the movable plate 25 can be adjusted. The shaft 23, which is rotated, can also be adjusted to multiple angles. When the movable plate 25 is at a horizontal angle to the ground, it can fix the base 11. When it is at a vertical angle to the ground, it can extend to the inner wall of the isolation cover 14 to protect the primary filter inside.

[0034] A threaded hole is provided through one end of the movable plate 25, and a plug is provided inside the threaded hole and protrudes outward.

[0035] The threaded hole allows the base 11 to be installed and fixed by inserting and tightening bolts, while the sealing head provides a sealed environment for the movable plate 25 when the primary filter is in use. The protruding design makes it easy to handle and disassemble.

[0036] Working principle: After multiple primary filters are placed and fixed in the fixing slot 31, the movable plate 25 is at the lower end and at a horizontal angle to the ground during the initial fixing of the primary filters. By increasing the contact friction, the structural stability of the base 11 can be improved. After the multiple primary filters are fixed, the movable plate 25 can be moved upward and extended to the inner wall of the isolation cover 14. The isolation cover 14 protects the primary filters inside. When removing the primary filters on the two sides, the movable plate 25 can be removed from the inner wall of the isolation cover 14 with the help of the sealing head.

[0037] This solution meets the needs of multi-functional use, enhances its applicability, and is formed by the material at the end of the isolation cover 14 itself, without increasing the cost of use. At the same time, it allows for convenient access to the pre-filters on both sides, making it convenient to use and meeting the requirements.

[0038] Please see Figure 1-5 As shown, this embodiment is based on the above embodiment:

[0039] It also includes a fixing structure, which includes fixing grooves 31 that are equidistantly opened at the middle of the upper end of the base 11;

[0040] The fixing groove 31, through its inner wall contact with the side of the primary filter, satisfies the need to fix a primary filter of a certain specification.

[0041] Movable tubes 32 are fixed on opposite sides of the inner wall of the fixed groove 31, and movable column 33 is connected inside the movable tube 32 by a movable spring. One end of the movable column 33 is rotatably connected to a fixed plate 34, and the inner side of the fixed plate 34 abuts against the two opposite sides of the primary filter.

[0042] The movable tube 32 is installed on the movable column 33 by a movable spring. With the help of the elastic force of the movable spring, the movable column 33 can be extended and retracted within the movable tube 32. Through the movable connection of the fixed plate 34, the lower end of the fixed plate 34 can be tilted inward to make the upper end open at a larger angle, which makes it easier to put the material into the primary filter. After the deformation is restored, the fixed plate 34 will resist it to make it suitable for fixing a primary filter of another specification.

[0043] Working principle: When fixing a primary filter of one specification, it is placed directly in the fixing groove 31. The stability of the structure is ensured by the contact between the two. When fixing a primary filter of another specification, the angle of a set of movable plates 25 is adjusted in advance, that is, the upper end of the movable plate 25 is expanded outward to make the upper part have a larger opening angle to facilitate the placement of the primary filter. Subsequently, under the application of inward pressure, the lower end of the movable plate 25 gradually moves outward to make the movable plate 25 perpendicular to the ground. After the force is released, the movable spring applies a reverse force, which links the movable plate 25 to contact the primary filter and fix it.

[0044] This solution can accommodate different specifications of pre-filters while allowing for simple and convenient adjustment, thus improving the performance.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
