Description

Technical Field

[0001] The utility model relates to the technical field of air filters, in particular to an air filter mounting seat. Background Art

[0002] Air filter is a device that captures dust from gas-solid two-phase flow and purifies the gas through the action of porous filter materials. It sends the low-dust air into the room after purification to ensure the process requirements of the clean room and the air cleanliness in the general air-conditioned room.

[0003] The Chinese utility model patent with the authorization announcement number "CN213761025U" is specifically "a mounting seat for an air filter". The specific implementation method of its specification records that "the mounting seat of the air filter, thanks to the arrangement of the first mounting plate, the second mounting plate and the third mounting plate, can rotate the knob to rotate the fixed shaft, thereby rotating the second gear, and the first gear meshing with the second gear rotates to drive the threaded shaft to rotate, so that the rectangular plate moves and drives the second mounting plate to move, so as to adjust the width and facilitate the installation of air filters of different specifications; thanks to the arrangement of the arc-shaped abutment plate, rotating the knob can make the extension beam move in the supporting beam, so that the two sets of symmetrically arranged arc-shaped abutment plates abut against the surface of the air filter, so as to fix the air filter, reduce the shaking of the air filter, and reduce the impact on subsequent use";

[0004] The technical solution of achieving the limiting fixation of the air filter by adjusting the distance between the arc-shaped abutment plate and the air filter, as well as the distance between each arc-shaped abutment plate, is not reasonable, because the purpose of achieving the adjustment is to be able to effectively squeeze and fix air filters of different specifications, but the specifications of air filters are diverse, and their surface contours are not necessarily compatible with the arc-shaped abutment plate, resulting in the arc-shaped abutment plate being unable to fully contact the surface of the air filter, resulting in a problem of small contact area, and then there is a problem of insufficient limiting fixation due to insufficient extrusion force. In addition, the mounting base and the wall are detachably installed through multiple bolt locking structures, but the action of tightening the bolts needs to be performed separately, resulting in inconvenience in loading and unloading due to many operating steps. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides an air filter mounting seat, which can effectively solve the problems of insufficient limiting fixation and inconvenient assembly and disassembly in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides an air filter mounting seat, comprising a base and two fixing seats fixedly mounted on the top of the base, two extrusion fixing components each comprising a mounting seat telescopically and slidably mounted above the base, a plurality of rubber extrusion heads being elastically mounted on opposite sides of the mounting seats, and two synchronous transmission components each comprising a screw which moves synchronously with the corresponding mounting seats and is spirally mounted on the bottom of the base.

[0008] Furthermore, a placement cavity is provided at the center of the top of the base, and two circular holes are provided at the bottom of the base, and the two screws are respectively screwed in the corresponding circular holes.

[0009] Furthermore, telescopic rods are slidably penetrated on both sides of the fixed seat, and movable plates are provided on the sides away from the two fixed seats. The ends of the telescopic rods away from each other are respectively fixedly installed on the corresponding movable plates, large springs are installed between the movable plates and the corresponding fixed seats, and handles are installed on the sides away from the movable plates.

[0010] Furthermore, a transmission cavity is provided in the fixing seat, a groove is provided at the bottom of each of the telescopic rods, and a rack is installed on one of the inner groove walls of the groove.

[0011] Furthermore, a small spring is installed between the mounting seat and the corresponding rubber extrusion head, and a limiting column arranged in the corresponding small spring is installed on one side of the mounting seat close to the rubber extrusion head.

[0012] Furthermore, the synchronous transmission assembly also includes a square tube and a square shaft which are arranged in the transmission cavity and slidably plugged into each other. The top end of the screw is installed on the lower bottom of the corresponding square tube, and the top end of the square shaft is installed with a rotating shaft extending into the corresponding groove, and the top end of the rotating shaft is installed with a gear which is meshed with the corresponding rack.

[0013] Compared with the known prior art, the technical solution provided by the utility model has the following beneficial effects:

[0014] 1. Two symmetrically distributed extrusion fixing components are set, and a number of elastically installed rubber extrusion heads in the extrusion fixing components are pressed against the air filter to achieve the limit fixation of the air filter. No matter the surface of the air filter is a plane, a curved surface or a polyhedron, each rubber extrusion head can be fully pressed against the surface of the air filter through the material characteristics of the rubber extrusion head itself and the compression deformation of the small spring behind it, so that each rubber extrusion head can be fully pressed against the surface of the air filter, which has the characteristics of sufficient limit fixation;

[0015] 2. Two screws that move synchronously with the extrusion fixing components are spirally installed under the base. When the two extrusion fixing components are pulled away from each other as a whole, the screws will be driven back into the base. When the two extrusion fixing components move toward each other as a whole and the air filter is squeezed and fixed, the screws will be spirally extended from the base, so that they can be directly screwed into the threaded holes on the wall. There is no need to tighten or loosen the screws separately, which reduces the operation steps and improves the loading and unloading efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model is further described below in conjunction with embodiments. Example 1

[0024] Reference Figure 1-4 , which is the first embodiment of the utility model, discloses an air filter mounting seat, including a base 1 and two fixing seats 2 fixedly installed on the top of the base 1, two extrusion fixing components 3 each include a mounting seat 31 telescopically and slidably installed above the base 1, and a plurality of rubber extrusion heads 32 are elastically installed on the opposite sides of the mounting seat 31. Through the deformation of the rubber extrusion head 32 and the compression of the small spring 33 behind it, the extrusion force on the air filter is increased, and the limiting and fixing effect is improved. The two synchronous transmission components 4 each include a screw 41 that moves synchronously with the corresponding mounting seat 31 and is spirally installed at the bottom of the base 1. Therefore, while the air filter is limited and fixed, the detachable installation between the entire mounting seat and the wall can also be completed. Example 2

[0025] Reference Figure 1-4 , which is the second embodiment of the utility model. The embodiment is different from the first embodiment in that: a placement cavity 11 is provided at the center of the top of the base 1, and two round holes 12 are provided at the bottom of the base 1. Two screws 41 are respectively screwed in the corresponding round holes 12. Telescopic rods 21 are slidably penetrated on both sides of the fixed seat 2. A movable plate 23 is provided on the far side of the two fixed seats 2. The far ends of the telescopic rods 21 are respectively fixedly installed on the corresponding movable plates 23. A large spring 22 is installed between the movable plate 23 and the corresponding fixed seat 2. The elastic force provided by the large spring 22 is greater than the elastic force of the plurality of small springs 33, so that when the large spring 22 elastically recovers, it can squeeze the plurality of small springs 33 to compress and deform them. A handle 24 is installed on the far side of the movable plate 23 to facilitate pulling to increase the distance between the two extrusion fixing components 3 and put in or take out the air filter. A transmission cavity is provided in the fixed seat 2. A groove is provided at the bottom of the telescopic rod 21, and a rack 25 is installed on one of the inner groove walls of the groove. A small spring 33 is installed between the mounting seat 31 and the corresponding rubber extrusion head 32. A limiting column 34 arranged in the corresponding small spring 33 is installed on the side of the mounting seat 31 close to the rubber extrusion head 32. The limiting column 34 can prevent the small spring 33 from being damaged due to excessive compression. The synchronous transmission assembly 4 also includes a square tube 42 and a square shaft 43 which are arranged in the transmission cavity and slidably plugged into each other. When the screw 41 is screwed into the corresponding threaded hole on the wall, the meshing relationship between the gear 45 and the rack 25 will not be destroyed through the relative sliding of the square tube 42 and the square shaft 43. The top end of the screw 41 is installed on the lower bottom of the corresponding square tube 42, and the top end of the square shaft 43 is installed with a rotating shaft 44 extending into the corresponding groove, and the top end of the rotating shaft 44 is installed with a gear 45 meshed with the corresponding rack 25.

[0026] The remaining structures are the same as those of Example 1.

[0027] The working principle of the utility model is as follows:

[0028] First, the corresponding telescopic rods 21 are pulled away from each other by the two handles 24, so that the two extrusion fixing components 3 are moved away from each other as a whole, and the distance between them is enlarged. At this time, the corresponding large springs 22 are forced to stretch to obtain elastic restoring force, and then the air filter to be fixed in position is placed in the placement cavity 11, and then the two handles 24 are released, and the corresponding movable plate 23 is pulled back by the elastic restoring force provided by the corresponding large springs 22, that is, the telescopic rods 21 are pulled back, so that the corresponding extrusion fixing components 3 are pushed closer to the air filter as a whole;

[0029] Secondly, the rubber extrusion heads 32 on the opposite side of the two mounting seats 31 will initially contact the surface of the air filter, but at this time the elastic restoring force of the large spring 22 has not been fully released, so it will continue to push the other rubber extrusion heads 32 to contact the surface of the air filter. At this time, the rubber extrusion heads 32 that first contact the air filter will increase the extrusion force on the surface of the air filter by means of compression of the small spring 33 behind it and its own deformation, thereby improving the limiting and fixing effect of the air filter;

[0030] Finally, as the large spring 22 elastically recovers and pulls the telescopic rod 21 back, the rack 25 in the groove at the bottom of the telescopic rod 21 will drive the corresponding gear 45 to rotate, thereby driving the rotating shaft 44, the square shaft 43, the square tube 42 and the screw 41 to rotate. Since the screw 41 is aligned with the threaded hole in the wall at this time, the screw 41 will be forced to be screwed into the threaded hole. At this time, the square shaft 43 will retract relative to the square tube 42 to ensure that the screw 41 can be screwed in smoothly. While completing the limit fixation of the air filter, the detachable installation between the entire mounting base and the wall is completed.

[0031] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some of the technical features therein by equivalents. These modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
