Description

Technical Field

[0001] The present invention relates to the technical field of air purification equipment processing, and more specifically, to a filter installation frame structure and a processing method thereof. Background Art

[0002] In many scenarios in various industries, it is necessary to filter and purify indoor and outdoor air to make the air reach a certain cleanliness standard. Industries such as electronics, medical, textiles, and communications require a large amount of air purification and filtration per unit time. Large-area air filtration and purification walls are mostly made of single air filters spliced ​​into filter walls.

[0003] The closest technology to the existing one is, announcement number: CN216572016U, a filter installation frame, which discloses a plurality of groups of vertical filter installation frame groups, an upper wall, and a lower wall. The plurality of groups of vertical filter installation frame groups are connected to each other and installed between the upper wall and the lower wall to form a filter wall covered with filters. A reinforcing rib is provided between the two adjacent vertical filter installation frame groups, one end of the reinforcing rib is vertically fixed to the upper wall, and the other end is vertically fixed to the lower wall, and both sides of the reinforcing rib are connected to the filter installation frame group in contact with it.

[0004] The existing filter is fixedly connected to the filter mounting frame through a spring buckle, but the spring buckle is easy to fall off before or after installation, making the filter mounting structure unstable.

[0005] In view of this, the present invention proposes a filter installation frame structure and a processing method which is not easy to fall off and has high structural strength. Summary of the invention

[0006] The purpose of the present invention is to provide a filter installation frame structure and a processing method which is not easy to fall off and has high structural strength.

[0007] A filter installation frame structure includes a frame 1 and a retaining spring 2, characterized in that: a slot assembly 3 is provided on one side of the frame 1, and an abutment interface 4 is provided on the other side of the frame 1. The diagonal slot assemblies 3 and the abutment interface 4 are centrally symmetrically arranged with the center of the frame 1. A retaining spring 2 is inserted in each slot assembly 3, one end of the retaining spring 2 is plugged into the slot, and the other end of the retaining spring 2 is abutted against the abutment interface 4. The retaining spring 2 includes a first connecting rod 21, a first bend 22, a second bend 23, a second connecting rod 24, and an installation hook 25. A first connecting rod 21 is inserted in each slot assembly 3, the first connecting rod 21 is connected to the second bend 23 through the first bend 22, the second bend 23 is connected to the installation hook 25 through the second connecting rod 24, and the installation hook 25 is abutted against the abutment interface 4.

[0008] In some embodiments, the first connecting rod 21 is a rod with an arc in the middle, so that the first connecting rod 21 can be easily rotated after being plugged into the slot assembly 3 .

[0009] In some embodiments, the second bend 23 is an “X”-shaped bend, which makes the force on the clamp spring 2 and the surface of the filter 5 more uniform when in contact with each other and does not damage the surface material of the filter 5 .

[0010] Furthermore, when the second connecting rod 24 is not in contact with the abutment interface 4, the second bend 23 has no contact with the surface of the filter 5, so that the retaining spring 2 and the surface of the filter 5 are relatively loose; when the second connecting rod 24 is rotated toward the abutment interface 4, the second bend 23 contacts and applies pressure to the surface of the filter 5, so that the retaining spring 2 and the surface of the filter 5 are tight; when the second connecting rod 24 is abutted and fixed with the abutment interface 4, the retaining spring and the surface of the filter are relatively tight, and the mounting hook 25 is the point of force for spinning.

[0011] In some embodiments, the distance between the bottom of the second bend 22 and the inner end of the frame 1 is d, and the distance between the end of the first connecting rod 21 and the end of the slot assembly 3 is D, d<D, so that the spring 2 will not fall off.

[0012] In some embodiments, the frame 1 is vertically bent to form four sub-frames 13 , and adjacent sub-frames 13 are perpendicular to each other.

[0013] In some embodiments, each sub-frame 13 is provided with a plurality of mounting holes 11 at intervals and in a staggered manner on the outside. When multiple frames 1 are installed, screws are locked and connected through corresponding mounting holes 11 on each sub-frame 13. The staggered mounting holes 11 allow for uniform force and prevent tipping.

[0014] In some embodiments, the inner wall of each sub-frame 13 is provided with a limiting portion 12 , and the limiting portion 12 protrudes from the inner wall of the frame 1 to limit the filter 5 installed in the frame.

[0015] In some embodiments, a method for processing a filter installation frame structure is characterized in that it includes the following steps: selecting a first sub-frame 13, plugging a first retaining spring 2 into a slot assembly 3 on the side of the sub-frame 13, and after the plugging is completed, bending it, and repeating it three times, so that the retaining spring 2 is installed, and an integrally bent frame 1 is obtained, which is connected and fixed to complete the assembly of the frame 1 and the four retaining springs 2, and full welding is used at the joints to improve strength and sealing performance.

[0016] The working principle of the present invention is as follows: first, the inlet of the filter 5 (the end with the sealing strip) is connected to one end of the frame 1, then the installation hook 2 is moved so that the first connecting rod 21 rotates along with the card slot assembly 3 until the second bend 23 abuts against the input port of the filter 5 (the end with the sealing strip), and finally the installation hook 2 abuts against the abutment interface 4 to complete the installation.

[0017] Beneficial effects of the present invention: The present invention proposes a filter installation frame structure and a processing method, wherein a slot assembly 3 is provided on one side of the four sides of the frame 1, and an abutment interface 4 is provided on the other side of the four sides of the frame 1. The diagonal slot assemblies 3 and the abutment interface 4 are centrally symmetrically arranged with the center of the frame 1, so that the retaining spring is not easy to fall off, and each of the slot assemblies 3 is inserted with a retaining spring 2, one end of the retaining spring 2 is inserted with the slot, and the other end of the retaining spring 2 is abutted with the abutment interface 4, the retaining spring 2 includes a first connecting rod 21, a first bend 22, a second bend 23, a second connecting rod 24, and an installation hook 25, and each of the slot assemblies 3 is inserted with a first connecting rod 21, the first connecting rod 21 is connected to the second bend 23 through the first bend 22, the second bend 23 is connected to the installation hook 25 through the second connecting rod 24, the installation hook 25 is abutted with the abutment interface 4, and the retaining spring structure is arranged in multiple stages, so that it can effectively install the filter 5.
