Description

Technical Field

[0001] This utility model relates to the field of gas filtration structure technology, specifically a gas filtration structure for ventilation and air conditioning. Background Technology

[0002] In modern building environments, the gas filtration structure of ventilation and air conditioning systems plays a crucial role, affecting not only indoor air quality but also the health and comfort of residents.

[0003] However, most existing ventilation and air conditioning gas filtration structures use screws or clips to install the filter screen. These methods often require tools such as screwdrivers or pliers for installation and disassembly, which is not only cumbersome but also easily damages the filter screen or surrounding components. Therefore, a new ventilation and air conditioning gas filtration structure is proposed to overcome the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a gas filtration structure for ventilation and air conditioning. By pressing the pressure rod to squeeze the stepped column, the second spring and the stepped column retract, releasing the fixed limit on the mounting frame. Then, by the action of the first mounting hole, the push block is pushed, thereby pushing the mounting frame to move and removing the filter structure from the mounting frame. This solves the problem that when installing and disassembling, tools such as screwdrivers or pliers are often needed, which is not only cumbersome but also easily damages the filter screen or surrounding components.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model relates to a gas filtration structure for ventilation and air conditioning, comprising a mounting frame and a filter structure. The mounting frame has mounting grooves on both sides of its interior. A third mounting hole is located at one end of the side of each mounting groove, and a second spring is installed inside the third mounting hole, with one end of the second spring connected to a stepped column. A second mounting hole is located at one end of the mounting frame, communicating with the mounting groove, and a pressure rod is fitted inside the second mounting hole. The filter structure includes two mounting frames, with a filter screen positioned between them. The mounting frames fit within the mounting grooves. A sliding groove is located at the top of the mounting frame, and a limiting groove is located on one side of each sliding groove, with the stepped column inserted into the limiting groove. The second mounting hole corresponds to the sliding groove.

[0007] Furthermore, one side of the bottom end of the compression rod is designed as a sloped structure.

[0008] Furthermore, the narrow end of the stepped column is designed as a sloping structure.

[0009] Furthermore, a first mounting hole is provided at one end of the mounting groove, and a first spring is provided inside the first mounting hole, with a push block connected to one end of the first spring.

[0010] Furthermore, the mounting frame has a U-shaped structure, and the two vertical rods of the mounting frame have an arc-shaped structure.

[0011] This utility model has the following beneficial effects:

[0012] This invention uses a pressing rod to compress the stepped column, causing the second spring and the stepped column to contract, releasing the fixed limit on the mounting frame. Then, through the action of the first mounting hole, a push block is pushed, thereby moving the mounting frame and removing the filter structure from the mounting frame. This solves the problem that during installation and disassembly, tools such as screwdrivers or pliers are often needed, which is not only cumbersome but also easily damages the filter screen or surrounding components.

[0013] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0019] 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.

[0020] Please see Figures 1-4This utility model provides a technical solution: a gas filtration structure for ventilation and air conditioning, including a mounting frame 1 and a filter structure 2. The mounting frame 1 has a U-shaped structure, and the two vertical rods of the mounting frame 1 have an arc-shaped structure. Mounting grooves 101 are respectively opened on both sides of the interior of the mounting frame 1. A third mounting hole 107 is opened at one end of the side of the mounting groove 101. A second spring 108 is installed inside the third mounting hole 107. One side of the bottom end of the pressure rod 106 is designed with a slope structure to facilitate the compression of the stepped column 109, causing it to contract. One end of the second spring 108 is connected to the stepped column 109. One side of the thin end of the stepped column 109 is designed with a slope structure to facilitate the compression of the stepped column 109 during the installation of the filter structure 2, causing it to contract and then be secured. In the limiting groove 203; one end of the mounting frame 1 is provided with a second mounting hole 105, which is connected to the mounting groove 101. A pressure rod 106 is fitted inside the second mounting hole 105. The pressure rod 106 is a cuboid structure. The filter structure 2 includes a mounting frame 201, which is an arc-shaped structure and corresponds to the mounting groove 101. There are two mounting frames 201, and a filter screen 204 is provided between the two mounting frames 201. The mounting frames 201 are fitted in the mounting groove 101. A sliding groove 202 is provided on the top of the mounting frame 201. A limiting groove 203 is provided on the side of one end of the sliding groove 202. The stepped column 109 is stuck in the limiting groove 203. The second mounting hole 105 corresponds to the sliding groove 202.

[0021] One end of the mounting slot 101 is provided with a first mounting hole 102. The first mounting hole 102 is provided with a first spring 103. One end of the first spring 103 is connected to a push block 104, which is a circular structure.

[0022] By pressing the pressure rod 106 to compress the stepped column 109, the second spring 108 and the stepped column 109 contract, releasing the fixed limit on the mounting frame 201. Then, under the action of the first mounting hole 102, the push block 104 is pushed, thereby pushing the mounting frame 201 to move and remove the filter structure 2 from the mounting frame 1. This solves the problem that during installation and disassembly, tools such as screwdrivers or pliers are often needed, which is not only cumbersome but also easily damages the filter screen or surrounding components.
