Description

Technical Field

[0001] This utility model relates to the field of filter installation technology, and in particular to an air conditioner filter installation structure. Background Technology

[0002] The air conditioning filter installation structure is a key component in an air conditioning system that connects the filter to the air conditioning equipment. Its main functions are reflected in the following core aspects, directly affecting the operating efficiency, safety, and ease of maintenance of the air conditioning system. The core function of the air conditioning filter is to filter impurities such as dust, particulate matter, and pollen from the air. The primary function of the installation structure is to firmly fix the filter in the air intake or return path of the air conditioner, ensuring that the filter will not shift or fall off due to airflow impact or equipment vibration during air conditioning operation. If the installation is not stable, gaps may appear between the filter and the equipment frame, causing unfiltered air to directly enter the system, reducing the filtration effect, and even affecting the lifespan of internal air conditioning components.

[0003] However, existing technologies, such as Chinese Publication No. CN214620042U, "An Installation Structure for a Vertical Air Conditioner Filter," which relates to the field of air conditioner filter technology, disclose an installation structure for a vertical air conditioner filter, including a fixing block, a connecting block, fixing bolts, a housing, and a filter element. The fixing block and connecting block are in four groups, with a connecting block between every two groups of fixing blocks. Each connecting block is movably connected to the two groups of fixing blocks via two sets of fixing bolts. The housing is located on the side of the fixing block and is fixedly connected to it. The filter element consists of several groups, each movably connected to a fixing block. This utility model improves upon this device, simplifying its structure and allowing for quick disassembly or installation by operators, effectively enhancing its flexibility. By adding a housing, a movable arm, and a movable mechanism, the device can be installed quickly, effectively improving its working efficiency.

[0004] However, this device does not have a linkage multi-directional clamping structure, which cannot firmly fix the filter in the installation position from multiple dimensions. This results in loosening and shaking due to uneven force at a single point. The multi-directional clamping cannot ensure that the filter frame fits evenly around the four sides of the installation frame, resulting in local deformation of the filter frame. It cannot protect the structural integrity of the filter by distributing the force, and is not suitable for paper or plastic frame filters with softer materials. Utility Model Content

[0005] The purpose of this invention is to solve the problems existing in the prior art, such as the inability to firmly fix the filter in the installation position from multiple dimensions, resulting in loosening and shaking due to uneven force at a single point; multi-directional clamping, which cannot ensure that the filter frame is evenly attached to the four sides of the installation frame, resulting in local deformation of the filter frame; the inability to protect the structural integrity of the filter by distributing force; and the unsuitability for filters with softer paper or plastic frame materials.

[0018] The technical effect of adopting the above-mentioned further solution is that the transverse threaded rod is located inside the protective shell and is protected from dust affecting the thread engagement.

[0019] In a preferred embodiment, the outer surface of the transverse threaded rod is threaded with a transverse internal threaded sleeve, the top of the transverse internal threaded sleeve is fixedly connected to a connecting rod, and the top of the connecting rod is fixedly connected to the bottom of the clamping plate.

[0020] The technical effect of adopting the above-mentioned further solution is that the rotating thread will drive the transverse internal thread sleeve, causing the connecting rod, sealing plate and wedge to move along the slotting direction of the wedge.

[0021] In a preferred embodiment, a sealing plate is fixedly connected to the inner surface of the air conditioner main housing, and a filter plate is provided inside the lower pressure block.

[0022] The technical effect of adopting the above-mentioned further solution is that the clamping plates move closer to the sealing plates to fix the bottom of the filter plate, and the pressing block presses down along the axis of the limiting rod to fix the top of the filter plate.

[0023] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0032] 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.

[0033] Example 1, please refer to Figures 1 to 5 This utility model provides a technical solution: an air conditioner filter installation structure, including an air conditioner main shell 1, characterized in that the top of the air conditioner main shell 1 is connected to an expansion shell 2, and two wedges 3 are opened at the bottom of the inner surface of the air conditioner main shell 1. Wedges 4 are movably embedded in the inner surface of the wedges 3, and clamping plates 5 are fixedly connected to the top of the two wedges 4.

[0034] The expansion shell 2 is equipped with a clamping assembly, which includes a fixing plate 6. One side of the fixing plate 6 is fixedly connected to the inner surface of the expansion shell 2. A limit rod 7 is fixedly connected to the top of the fixing plate 6. The top of the limit rod 7 is fixedly connected to the inner surface of the expansion shell 2. A limit sleeve 8 is movably sleeved on the outer surface of the limit rod 7. A lower pressure block 9 is fixedly connected to one side of the limit sleeve 8. A longitudinal internal threaded sleeve 10 is fixedly connected to the side of the lower pressure block 9 away from the limit sleeve 8. A longitudinal threaded rod 11 is threadedly connected to the inner surface of the longitudinal internal threaded sleeve 10.

[0035] In this embodiment, the longitudinal threaded rod 11 rotates inside the air conditioner main housing 1. The rotating thread will drive the longitudinal threaded rod 11, and the rotating thread will drive the longitudinal internal threaded sleeve 10, so that the lower pressure block 9 and the limiting sleeve 8 move along the axial direction of the limiting rod 7. The limiting rod 7 is fixed inside the expansion housing 2 by the fixing plate 6. Therefore, the rotating thread will drive the lower pressure block 9 to press down along the axial direction of the limiting rod 7, and fix the top of the filter plate 20.

[0036] Example 2, please refer to Figures 1 to 5 The top of the longitudinal threaded rod 11 is rotatably connected to the inner surface of the expansion shell 2, and the outer surface of the longitudinal threaded rod 11 is rotatably connected to the bottom of the air conditioner main shell 1. The bottom of the longitudinal threaded rod 11 is fixedly connected to a driven bevel gear 12, and the outer surface of the driven bevel gear 12 is meshed with a driving bevel gear 13. A transverse threaded rod 14 is fixedly embedded inside the driving bevel gear 13. A knob 15 is fixedly connected to one end of the transverse threaded rod 14. A protective shell 16 is rotatably connected to the outer surface of the transverse threaded rod 14. The top of the protective shell 16 is fixedly connected to the bottom of the air conditioner main shell 1. A transverse internal threaded sleeve 17 is threadedly connected to the outer surface of the transverse threaded rod 14. A connecting rod 18 is fixedly connected to the top of the transverse internal threaded sleeve 17. The top of the connecting rod 18 is fixedly connected to the bottom of the clamping plate 5.

[0037] In this embodiment, the transverse threaded rod 14 is rotated inside the protective shell 16 by the knob 15. The rotation of the thread will drive the transverse internal threaded sleeve 17, so that the connecting rod 18, the sealing plate 19 and the wedge 4 move along the slotting direction of the wedge 3, and make the clamping plate 5 move closer to the sealing plate 19 to fix the bottom of the filter plate 20.

[0038] Working principle: First, the filter plate 20 is placed between the sealing plate 19 and the clamping plate 5, and located at the bottom of the lower pressure block 9. Then, the transverse threaded rod 14 is rotated inside the protective shell 16 by the knob 15. The rotation of the thread will drive the transverse internal threaded sleeve 17, causing the connecting rod 18, the sealing plate 19 and the wedge 4 to move along the slotting direction of the wedge 3, and causing the clamping plate 5 to move closer to the sealing plate 19, fixing the bottom of the filter plate 20. At the same time, the driving bevel gear 13, which rotates with the transverse threaded rod 14, will drive the longitudinal threaded rod 11 to rotate inside the air conditioner main shell 1 under the meshing action of the driven bevel gear 12. The rotation of the thread will drive the longitudinal threaded rod 11, and the rotation of the thread will drive the longitudinal internal threaded sleeve 10, causing the lower pressure block 9 and the limiting sleeve 8 to move along the axis of the limiting rod 7. The limiting rod 7 is fixed inside the expansion shell 2 by the fixing plate 6, so the rotation of the thread will drive the lower pressure block 9 to press down along the axis of the limiting rod 7, fixing the top of the filter plate 20.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
