Description
Technical Field
[0001] This utility model relates to the technical field of filter installation devices, and in particular to a multi-stage filter installation device for the air inlet of a cabinet air conditioner. Background Technology
[0002] As a key heat dissipation component for equipment such as communication base stations, data centers, and industrial control cabinets, the air filtration effect of the air inlet of the server rack directly affects the operational stability and lifespan of the equipment inside the rack. The environment in which server racks are located (such as outdoor base stations and factory workshops) often contains pollutants of various particle sizes, including large dust particles, fine dust, and ultrafine dust. If these pollutants enter the rack, they will gradually adhere to the surface of circuit boards and heat sinks, leading to reduced heat dissipation efficiency, short circuits, or even system downtime. Traditional devices often use single-stage filters. If a large-pore filter is used, it can intercept coarse dust but cannot filter ultrafine dust, resulting in continuous intrusion of fine dust. If a small-pore filter is used, it is easily clogged by large particles, and frequent maintenance will negatively impact equipment operation. The limited pore size of a single filter creates a "filtration blind spot," making it unsuitable for complex environments where multiple particle sizes of pollutants coexist. Although some equipment uses a multi-stage filter design, each group of filters needs to be individually fixed with clips and bolts. Replacement requires disassembling each group one by one, with each maintenance taking 10-15 minutes. This is especially difficult and inefficient in high-altitude cabinets or confined spaces, often leading to filter blockage due to untimely maintenance, air conditioning failure, and equipment overheating protection shutdown. Therefore, we propose a multi-stage filter installation device for the air conditioning inlet of a cabinet to solve this problem. Utility Model Content
[0003] The purpose of this utility model is to provide a multi-stage filter installation device for the air inlet of a cabinet air conditioner to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: A multi-stage filter installation device for the air inlet of a cabinet air conditioner includes: a cabinet air conditioner body; a protective shell fixedly installed on the front side of the cabinet air conditioner body; filter plate one, filter plate two, and filter plate three are arranged inside the protective shell; two sets of protrusions are arranged on both sides of filter plate one, filter plate two, and filter plate three; twelve sets of protrusions are slidably installed inside both sides of the protective shell; placement grooves are opened inside both sides of the protective shell; installation components are arranged inside both sets of placement grooves; the installation components include: a first inclined block; two inclined blocks two are movably abutting against the inclined surfaces of the first inclined block; three sets of inserts are fixedly installed on the opposite sides of the two sets of second inclined blocks; the three sets of inserts on the same side are movably arranged inside the corresponding protrusions; a first spring is arranged on one side of the first inclined block; a fixing block is arranged on one side of the two sets of second inclined blocks; and a second spring is arranged on the opposite sides of the two sets of fixing blocks.
[0005] Preferably, a connecting shaft is fixedly installed on the side of each of the two sets of inclined blocks that are far apart from each other, and the two sets of springs are respectively sleeved on the outside of the corresponding connecting shaft. The two ends of the two sets of springs are respectively fixedly connected to the corresponding inclined block and the inner wall of one side of the placement groove.
[0006] Preferably, the two sets of fixed blocks on the same side are fixedly connected to the corresponding inclined blocks 2 respectively. Limiting rods are slidably installed inside the four sets of fixed blocks. The ends of the two sets of limiting rods on the same side that are far apart from each other are fixedly connected to the inner wall of one side of the corresponding placement groove respectively. The four sets of springs 2 are respectively sleeved on the outside of the corresponding limiting rods. The two ends of the two sets of springs 2 on the same side are fixedly connected to the corresponding fixed blocks and the inner wall of one side of the placement groove respectively.
[0007] Preferably, the two sets of connecting shafts slide through to both sides of the cabinet air conditioner, and pull plates are fixedly installed at the ends of the two sets of connecting shafts that are far apart from each other. Two sets of guide rods are fixedly installed on the sides of the two sets of inclined blocks that are far apart from each other. The two sets of guide rods located on the same side are slidably installed inside the corresponding placement slots.
[0008] Preferably, filter plate one and filter plate two abut against each other, filter plate two and filter plate three abut against each other, and the apertures of filter plate one, filter plate two and filter plate three decrease in size sequentially.
[0009] Preferably, each of the twelve sets of protrusions has a slot inside, and the twelve sets of inserts are respectively adapted to the corresponding slots.
[0010] In this utility model, a multi-stage filter installation device for the air inlet of a cabinet air conditioner is provided. It consists of filter plate one, filter plate two, filter plate three, and an installation assembly. Pulling the two side plates outward causes the connecting shaft and the compression spring of the inclined block one to move outward, releasing the squeezing force on the inclined block one and the inclined block two. Under the restoring force of the spring two, the inclined block two slides inward, causing the insert to disengage from the slot of the protrusion. The filter plate one, filter plate two, and filter plate three form a gradient filter with progressively smaller pore sizes, intercepting large dust particles, fine dust, and ultrafine dust in the air layer by layer. This avoids filtration blind spots caused by the pore size limitation of a single filter, ensuring the cleanliness of the airflow entering the cabinet, reducing dust accumulation inside the equipment, extending the maintenance cycle, and facilitating the quick installation and removal of the three-stage filter plates. It also facilitates cleaning, maintenance, or replacement of the multi-stage filter plates, improving maintenance efficiency and preventing air conditioning failure due to untreated filter blockage.

Detailed Implementation
[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0014] Reference Figure 1-5 A multi-stage filter installation device for the air inlet of a cabinet air conditioner includes: a cabinet air conditioner body 1; a protective shell 2 fixedly installed on the front side of the cabinet air conditioner body 1; filter plate 3, filter plate 4, and filter plate 5 are arranged inside the protective shell 2; two sets of protrusions are provided on both sides of filter plate 3, filter plate 4, and filter plate 5; twelve sets of protrusions are slidably installed inside both sides of the protective shell 2; placement grooves are opened inside both sides of the protective shell 2; and installation components 6 are arranged inside both sets of placement grooves. Mounting component 6 includes: a first inclined block 603, with two inclined blocks 604 movably abutting each other on both sides of the first inclined block 603; three sets of insert blocks 605 are fixedly installed on the side of the two sets of second inclined blocks 604 that are far apart from each other; the three sets of insert blocks 605 located on the same side are respectively movably arranged inside the corresponding protrusions; a first spring 607 is provided on one side of the first inclined block 603; a fixing block 606 is provided on one side of the two sets of second inclined blocks 604; and a second spring 608 is provided on the side of the two sets of fixing blocks 606 that are far apart from each other.
[0015] In this embodiment, connecting shafts 602 are fixedly installed on the opposite sides of the two sets of inclined blocks 603. Two sets of springs 607 are respectively sleeved on the outer side of the corresponding connecting shafts 602. The two ends of the two sets of springs 607 are respectively fixedly connected to the corresponding inclined block 603 and the inner wall of one side of the placement groove, which facilitates the quick reset of the inclined blocks 603 and the installation and disassembly of the filter plate 3, filter plate 4, and filter plate 5. Two sets of fixing blocks 606 located on the same side are respectively fixedly connected to the corresponding inclined block 604. The four sets of fixing blocks 606 are fixedly connected to the corresponding inclined block 604. Limiting rods 610 are slidably installed inside the fixed block 606. The ends of the two sets of limiting rods 610 on the same side, which are far apart from each other, are fixedly connected to the inner wall of the corresponding placement groove. Four sets of springs 608 are respectively sleeved on the outside of the corresponding limiting rods 610. The two ends of the two sets of springs 608 on the same side are fixedly connected to the corresponding fixed block 606 and the inner wall of the placement groove, which facilitates the quick reset of the insert block 605 and the quick installation and removal of filter plate 3, filter plate 4 and filter plate 5.
[0016] In this embodiment, two sets of connecting shafts 602 slide through to both sides of the cabinet air conditioner. Pull plates 601 are fixedly installed at the ends of the two sets of connecting shafts 602 that are far apart from each other. Two sets of guide rods 609 are fixedly installed on the sides of the two sets of inclined blocks 603 that are far apart from each other. The two sets of guide rods 609 on the same side are slidably installed inside the corresponding placement slots to facilitate the stable sliding of the inclined blocks 603. Filter plate 3 and filter plate 4 abut against each other, and filter plate 4 and filter plate 5 abut against each other. The apertures of filter plate 3, filter plate 4 and filter plate 5 decrease sequentially to facilitate multi-stage filtration. Slots 7 are opened inside the twelve sets of protrusions. The twelve sets of inserts 605 are adapted to the corresponding slots 7 respectively, which facilitates the more stable installation of filter plate 3, filter plate 4 and filter plate 5.
[0017] In this embodiment, during use, the device integrates and installs filter plate 3, filter plate 4, and filter plate 5 through the protective shell 2. The three-stage filter plates form a gradient filtration by successively decreasing the aperture size. Precise positioning is achieved by sliding the two side protrusions along the inner wall of the protective shell 2. When installing the filter plates, in the initial state, the elastic force of spring 607 pushes the inclined block 603 to move inward, and its two side inclined surfaces squeeze the inclined block 604, forcing the two sets of inclined blocks 604 to slide outward along the limiting rod 610 and compress the spring 608. The inclined block 604 simultaneously drives the three sets of insert blocks 605 to extend. When the protrusion of the filter plate is inserted into the corresponding position of the protective shell 2, the insert block 605 is just embedded in the slot 7 of the protrusion, realizing the synchronous fixation of the three-stage filter plates, ensuring that the filter plates are tightly connected, and preventing the airflow from flowing directly without filtration. When the filter plates need to be replaced or cleaned, pull the two pull plates 601 outwards, which will cause the connecting shaft 602 and the first inclined block 603 to compress the first spring 607 to move outwards, and the squeezing force of the first inclined block 603 on the second inclined block 604 will be released; the second inclined block 604 will slide inwards under the restoring force of the second spring 608, which will cause the insert 605 to disengage from the slot 7 of the protrusion. At this time, the first filter plate 3, the second filter plate 4, and the third filter plate 5 can be directly pulled out for maintenance; after maintenance, reinsert the filter plates, release the pull plates 601, the first spring 607 will push the first inclined block 603 to reset, and the insert 605 will be inserted into the slot 7 again to complete the fixation.
