Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning filter technology, specifically an automotive air conditioning filter fixing frame. Background Technology

[0002] An air filter element is a type of filter, also called an air filter cartridge, air cleaner, etc. It is mainly used for air filtration in engineering vehicles, automobiles, agricultural vehicles, laboratories, sterile operating rooms, and various precision operating rooms. During engine operation, a large amount of air is drawn in. If this air is not filtered, suspended dust in the air will be sucked into the cylinders, accelerating the wear of the piston assembly and cylinders. Larger particles entering between the piston and cylinder can cause severe "cylinder scoring," which is particularly serious in dry and sandy working environments. The air filter is installed in front of the carburetor or intake manifold to filter out dust and sand particles from the air, ensuring that sufficient clean air enters the cylinders.

[0003] An investigation revealed that a Chinese utility model or invention patent (publication number: CN219333599U) discloses a mounting frame for an automotive air conditioning filter. The frame includes a rectangular cross-section frame with a support mesh at its bottom. The frame has an inner end and an outer end. Guide plates are inclinedly arranged on both sides of the inner end, with the two guide plates facing each other. One guide plate's end, away from the other, is connected to the edge of the frame. The projection of the guide plate along the length of the frame lies within the projection of the frame along its length. This utility model provides a mounting frame for an automotive air conditioning filter that reduces operational difficulty.

[0004] Although the aforementioned patent reduces the operational difficulty of the fixing frame for automotive air conditioning filters by setting up components such as support nets and guide plates, the existing fixing frames for automotive air conditioning filters are too difficult to install and remove, resulting in excessive time and effort, low work efficiency.

[0005] Therefore, this utility model provides a car air conditioning filter fixing frame to solve the above problems. Utility Model Content

[0018] (III) Beneficial Effects

[0019] 1. This application utilizes the rotational force of the motor-driven rotating rod in conjunction with components such as the fixed rod, rotating rod, connecting plate A, and connecting plate B. This allows the motor to drive the rotating rod to rotate, which in turn drives the connecting plate A to rotate, which in turn drives the connecting plate B to rotate. This causes the connecting plate B to move the fixed frame horizontally within the fixed groove, thus securing the fixed frame. This achieves the effect of making it difficult to install, remove, and fix the air conditioning filter, avoiding excessively long installation and removal times due to improper installation or removal.

[0020] 2. This application utilizes the thrust generated by the horizontal displacement of the fixing frame within the fixing groove via the connecting plate B to cause the airbag on one side of the fixing frame to contract under pressure. When the airbag contracts and releases force, it draws lubricant from the material bucket through the long pipe and sprays the lubricant out through the water spray pipe connected to the other end of the airbag. This achieves the effect of preventing the parts of the connecting plate A, connecting plate B, and short rod from rusting and aging due to long-term rotation during the installation of the air conditioning filter, which would otherwise be inconvenient for continued use.

[0027] 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.

[0028] This utility model provides a fixing frame for automotive air conditioning filters, such as... Figures 1-5 As shown, the automotive air conditioning filter fixing frame includes a filter frame structure 1, which includes a filter box 101. A filter screen 102 is provided on the inner wall of the filter box 101. A fixing plate A103 is fixedly connected to one side of the filter box 101, and a support frame 104 is fixedly connected to one side of the fixing plate A103. A fixing plate B105 is fixedly connected to the side of the filter box 101 away from the fixing plate A103. A fixing device 2 is provided on the outside of the filter frame structure 1. The fixing device 2 includes a motor 201. The motor 201 is fixedly connected to the side of the fixing plate B105 away from the filter box 101. A fixing rod 202 is fixedly connected to the output shaft of the motor 201. A rotating rod 203 passes through the end of the fixing rod 202 away from the motor 201 and is rotatably connected to the rotating rod 203.

[0029] A support plate 204 is fixedly connected to the side of motor 201 away from the fixed plate B105. A fixing groove 205 is opened on the side of support plate 204 away from motor 201. A connecting plate A206 is rotatably connected to the end of rotating rod 203 away from fixed rod 202. A short rod 207 passes through the side of connecting plate A206 away from rotating rod 203 and is rotatably connected to the short rod 207. A connecting plate B208 is rotatably connected to the side of connecting plate A206 near the short rod 207. A lead screw 209 passes through one side of connecting plate B208. A fixed frame 210 is rotatably connected to the side of connecting plate B208 away from connecting plate A206. The above design is conducive to driving the fixed frame 210 to slide through the connection and rotation of connecting plate A and connecting plate B, so that the fixed frame 210 can be displaced in the horizontal direction.

[0030] There are two support frames 104, which are symmetrical to each other along the vertical central axis of the fixed plate A103. There are several filter screens 102, which are arranged in a linear array on the inner wall of the filter cartridge box 101. The above design is conducive to filtering dust through the filter screens 102, preventing too much dust from entering and clogging the parts, causing damage to the parts.

[0031] A lubrication device 3 is provided on the outside of the filter element frame structure 1. The lubrication device 3 includes a short plate 301, which is fixedly connected to the side of the fixed plate B105 away from the filter element box 101. A material tank 302 is fixedly connected to the top of the short plate 301. A one-way valve 303 is fixedly connected to the circumference of the material tank 302. A long pipe 304 passes through the end of the one-way valve 303 away from the material tank 302 and is fixedly connected to it. The long pipe 304 is located away from the one-way valve 304. One end of the tube 304 is connected to a long plate 305 and fixedly connected to the long plate 305. An air bladder 306 is provided on the side of the long plate 305 away from the one-way valve 303. The end of the long tube 304 away from the one-way valve 303 passes through the circumferential surface of the air bladder 306 and is fixedly connected to the air bladder 306. One end of the air bladder 306 is connected to a water spray pipe 307 and is fixedly connected to the water spray pipe 307. The above design is beneficial to prevent the lubricant in the long tube 304 from flowing back through the one-way valve 303.

[0032] The circumferential surface of the airbag 306 is fixedly connected to one end of the long tube 304, and the fixing plate B105 is fixedly connected to one side of the long plate 305. The above design is conducive to fixing the position of the airbag 306 through the long plate 305 and preventing the airbag 306 from shifting.

[0033] The airbag 306 is made of silicone. The long plate 305 is located between the one-way valve 303 and the airbag 306. The above design is conducive to drawing the lubricant in the material bucket 302 through the airbag 306, so that the lubricant can be sprayed on the parts to prevent the parts from rusting and aging.

[0034] The bottom of the fixing frame 210 is slidably connected to the fixing groove 205. There are two fixing frames 210, which are symmetrical to each other along the vertical central axis of the support plate 204. The above design is conducive to limiting the fixing frame 210 through the fixing groove 205, so that the fixing frame 210 can move horizontally within the fixing groove 205.

[0035] The working process of this utility model is as follows: This application drives the rotating rod 203 through the fixed rod 202 to rotate via the motor 201, thereby causing the rotating rod 203 to drive the connecting plate A206 to rotate, which in turn causes the connecting plate B connected by the lead screw 209 to rotate. This causes the fixed frame 210 connected by the lead screw 209 to move horizontally within the fixed groove 205 opened on the support plate 204, thereby enabling the fixed frame 210 to achieve a fixed clamping effect. This achieves the effect of making it difficult to install, disassemble, and fix the air conditioning filter, avoiding excessive time and effort during installation and removal due to improper installation and removal.

[0036] Meanwhile, an airbag 306 is provided on one side of the fixed frame 210. When the fixed frame 210 moves outward, it touches the airbag 306 on the long plate 305, causing the airbag 306 to contract. Through the contraction of the airbag 306, the lubricant in the material barrel 302 flows into the airbag 306 through the long pipe 304, thereby spraying the lubricant in the airbag 306 out through the water spray pipe 307 penetrating one end of the airbag 306. This lubricant is sprayed onto the parts, thereby increasing the service life of the device by lubricating the parts that are rusted and aged due to the long-term rotation between the connecting plate A, connecting plate B and short rod components during the installation of the air conditioning filter element.

[0037] The above description is only the best specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and utility model concept of this utility model, should be included within the protection scope of this utility model.
