Description

Technical Field

[0001] This utility model relates to the field of air-cooled cabinet air conditioner technology, and more specifically, to an adjustable air guide plate structure for the air supply box of an air-cooled cabinet air conditioner. Background Technology

[0002] Air-cooled cabinet air conditioners are a type of refrigeration equipment widely used in commercial and industrial fields. They deliver cold air to the space that needs to be refrigerated through an air supply box. They are widely used due to their high efficiency in heat dissipation and convenient installation. The airflow organization of their air supply system directly affects the cooling effect and energy efficiency.

[0003] In existing air-cooled cabinet air supply boxes, traditional air guides are mostly fixed angles or graded adjustments, which are difficult to meet complex air supply needs. The angle is fixed at the factory and cannot be dynamically adjusted according to changes in spatial layout, resulting in a fixed airflow coverage area and uneven distribution. Especially in narrow spaces or multi-zone cooling scenarios, it is impossible to accurately match the needs. Graded adjustments usually only provide 0 degrees, 30 degrees, and 60 degrees of adjustment, with few adjustment levels and a large range, which is difficult to adapt to subtle changes in airflow direction and has insufficient adjustment accuracy. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an adjustable air guide plate structure for the air supply box of an air-cooled cabinet air conditioner, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable air guide plate structure for an air-cooled cabinet air supply box includes an air supply frame fixedly installed on one side of the air supply box, a fixed frame is provided through one side of the air supply frame, and an adjustment mechanism is provided inside the fixed frame.

[0007] The adjustment mechanism includes a limiting frame fixedly installed on the inner wall of the fixed frame, a U-shaped frame slidably installed inside the limiting frame, multiple rollers rotatably installed at the bottom of the U-shaped frame, a lower gear groove plate fixedly installed at the top of the U-shaped frame, multiple gears meshing on the surface of the lower gear groove plate, a rotating rod fixedly installed at one end of the gear, and a wind guide plate fixedly installed on the surface of the rotating rod.

[0008] One end of each rotating rod passes through the fixed frame and extends into the air supply frame, and the air guide plate is set in an arc shape.

[0009] By adopting the above technical solution: the gear transmission drives the arc-shaped air guide plate to rotate, which can accurately adjust the air delivery direction and diffusion angle to meet the air delivery needs of different scenarios. Moreover, the roller design at the bottom of the U-shaped frame reduces sliding friction, and with the gear meshing transmission, the adjustment process is smooth and stable, reducing mechanical loss. Secondly, the arc-shaped air guide plate design can improve the airflow pattern, enhance the uniformity and coverage of air delivery, and enhance the energy efficiency of the air-cooled cabinet air conditioner.

[0010] As a further description of the above technical solution: the fixed frame is provided with a guide mechanism, the guide mechanism includes an upper gear groove plate fixedly disposed inside the fixed frame, an L-shaped protrusion strip fixedly disposed on one side of the upper gear groove plate, a sliding groove is opened on the surface of the fixed frame, the L-shaped protrusion strip is slidably connected to the sliding groove, an L-shaped guide block is fixedly disposed on one side of the air supply frame, a guide groove is opened on the surface of the upper gear groove plate, and the L-shaped guide block is slidably connected to the guide groove;

[0011] A mounting box is fixedly installed on one side of the fixed frame. The surface of the mounting box has multiple heat dissipation holes. A small stepper motor is fixedly installed inside the mounting box. A rotating shaft is fixedly installed at the output end of the small stepper motor. One of the gears is fixedly connected to the rotating shaft.

[0012] By adopting the above technical solution, the dual limiting of the L-shaped protrusion and the slide groove, and the L-shaped guide block and the guide groove, ensures that the gear and the upper and lower gear slot plates are always precisely meshed, avoiding transmission shaking or jamming. Moreover, the angle of the air guide plate can be steplessly adjusted through the control system, with sensitive response and high adjustment accuracy.

[0013] As a further description of the above technical solution: the air guide plate is made of aluminum alloy, and an anti-corrosion layer is fixedly provided on the surface of the air guide plate, the anti-corrosion layer being made of epoxy resin coating material;

[0014] A dustproof net is fixedly installed on one side of the air supply frame, and the air supply frame and the fixed frame are made of cold-rolled steel plate.

[0015] By adopting the above technical solutions, the synergistic effect of anti-corrosion materials and dustproof design reduces the problems of rust on the air guide plate and dust accumulation on transmission components, reduces the frequency of cleaning and replacement, and improves the economy and service life of the equipment.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] By setting up an adjustment mechanism, compared with existing technologies, the meshing transmission of gears and lower gear slot plates, combined with the friction reduction design of rollers, makes the sliding process of the U-shaped frame smooth and stable with low power transmission loss. It can realize the synchronous and precise adjustment of multiple sets of air guide plates. Moreover, the small stepper motor drives the shaft to rotate the gear set. The motor speed and direction can be precisely controlled by the control system to achieve stepless adjustment of the air guide plates at multiple angles. This achieves efficient power transmission and precise limit, avoids the transmission defects of traditional mechanical structures, and improves the stability and synchronization of adjustment. In addition, the air guide plates are made of aluminum alloy and covered with an epoxy resin anti-corrosion layer. Combined with the fixed frame of cold-rolled steel plate, they can withstand long-term high wind speed impact and humid environment, reducing maintenance costs.

[0018] By setting up a guiding mechanism, compared with existing technologies, the stable transmission path formed by the double guiding and limiting structure of L-shaped protrusions and fixed frame grooves, and L-shaped guide blocks and guide grooves effectively suppresses the lateral offset or axial movement of gears during meshing. It is especially suitable for high-frequency adjustment scenarios and can maintain precise transmission even after long-term use. Secondly, the guiding mechanism does not require additional drive components and achieves its function only through mechanical limiting. It is deeply integrated with the gear transmission system of the adjustment mechanism, occupies little space and is easy to install, and improves the overall reliability of the mechanism. The dustproof net of the air supply frame can intercept dust, hair and other impurities in the air, reduce dust accumulation and wear on the air guide plate and internal transmission components, and extend the maintenance cycle.

[0025] 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.

[0026] The embodiments disclosed in this application are as follows: Figure 1-5 The adjustable air guide plate structure of the air supply box of the air-cooled cabinet unit shown includes an air supply frame 1 fixedly installed on one side of the air supply box, a fixed frame 2 through one side of the air supply frame 1, and an adjustment mechanism inside the fixed frame 2.

[0027] The adjustment mechanism includes a limiting frame 3 fixedly installed on the inner wall of the fixed frame 2, a U-shaped frame 4 slidably installed inside the limiting frame 3, multiple rollers 5 rotatably installed at the bottom of the U-shaped frame 4, a lower gear groove plate 6 fixedly installed at the top of the U-shaped frame 4, multiple gears 7 meshing on the surface of the lower gear groove plate 6, a rotating rod 8 fixedly installed at one end of the gear 7, and a guide plate 9 fixedly installed on the surface of the rotating rod 8.

[0028] One end of the rotating rod 8 passes through the fixed frame 2 and extends into the air supply frame 1, and the air guide plate 9 is set in an arc shape;

[0029] When it is necessary to adjust the angle of the air guide plate 9, the operator connects the small stepper motor 15 to the external power supply, and then starts the small stepper motor 15 in the mounting box 14. The output end of the small stepper motor 15 drives the rotating shaft 16 to rotate. Since one of the gears 7 is fixedly connected to the rotating shaft 16, the gear 7 will start to rotate with the rotating shaft 16.

[0030] Moreover, after the gear 7 connected to the rotating shaft 16 rotates, it drives the lower gear groove plate 6 to move through the meshing relationship. The lower gear groove plate 6 drives the U-shaped frame 4 to slide within the limiting frame 3. The roller 5 at the bottom of the U-shaped frame 4 rolls at the bottom of the limiting frame 3, reducing the friction when the U-shaped frame 4 slides.

[0031] At the same time, the other gears 7 that mesh with the lower gear slot plate 6 also begin to rotate, and these gears 7 drive the rotating rod 8 fixed at one end to rotate.

[0032] When the rotating rod 8 rotates, the air guide plate 9 fixed on the surface of the rotating rod 8 rotates accordingly, thereby adjusting the angle of the air guide plate 9. Since the air guide plate 9 is set in an arc shape, it can change the airflow direction and diffusion angle during rotation to meet different air supply needs.

[0033] Reference Figure 2-4As shown, the fixed frame 2 is provided with a guide mechanism inside. The guide mechanism includes an upper gear groove plate 10 fixedly installed inside the fixed frame 2. An L-shaped protrusion 11 is fixedly installed on one side of the upper gear groove plate 10. A sliding groove is opened on the surface of the fixed frame 2. The L-shaped protrusion 11 is slidably connected to the sliding groove. An L-shaped guide block 12 is fixedly installed on one side of the air supply frame 1. A guide groove 13 is opened on the surface of the upper gear groove plate 10. The L-shaped guide block 12 is slidably connected to the guide groove 13.

[0034] A mounting box 14 is fixedly installed on one side of the fixed frame 2. Multiple heat dissipation holes are provided on the surface of the mounting box 14. A small stepper motor 15 is fixedly installed inside the mounting box 14. A rotating shaft 16 is fixedly installed at the output end of the small stepper motor 15. One of the gears 7 is fixedly connected to the rotating shaft 16.

[0035] Meanwhile, during the rotation of gear 7 and the movement of lower gear slot plate 6, upper gear slot plate 10 slides in the groove of fixed frame 2 through L-shaped protrusion 11, and L-shaped guide block 12 slides in guide groove 13, which guides and limits upper gear slot plate 10, ensuring that gear 7, lower gear slot plate 6 and upper gear slot plate 10 always maintain a good meshing relationship, so that the transmission process is stable and reliable.

[0036] Reference Figure 1 , 5 As shown, the air guide plate 9 is made of aluminum alloy, and an anti-corrosion layer 17 is fixedly provided on the surface of the air guide plate 9. The anti-corrosion layer 17 is made of epoxy resin coating material.

[0037] A dustproof net 18 is fixedly installed on one side of the air supply frame 1. The air supply frame 1 and the fixed frame 2 are made of cold-rolled steel plate.

[0038] Furthermore, when the small stepper motor 15 is working continuously, the heat dissipation holes on the surface of the mounting box 14 can help the motor dissipate heat and prevent the motor from being affected or damaged due to overheating. When the air-cooled cabinet air conditioner delivers air, the air passes through the air delivery frame 1, is initially filtered by the dust filter 18, and then passes through the air guide plate 9 with the angle adjusted, and is delivered in a specific direction and angle to achieve precise air delivery.

[0039] Since the air guide plate 9 is made of aluminum alloy and has an anti-corrosion layer 17 on its surface, it can be guaranteed to be resistant to corrosion during long-term use and to stably perform its air guiding function.

[0040] Working principle of this utility model:

[0041] This utility model is an adjustable air guide plate structure for the air supply box of an air-cooled cabinet air conditioner. When the air-cooled cabinet air conditioner is not started and the air guide plate angle is adjusted, the components are in a relatively static state. The U-shaped frame 4 is stationary in the limiting frame 3, the roller 5 is in contact with the bottom of the limiting frame 3 but does not roll, the lower gear groove plate 6 and the gear 7 are engaged, the air guide plate 9 is at the initial angle, the L-shaped protrusion 11 of the upper gear groove plate 10 is stationary in the sliding groove of the fixed frame 2, the L-shaped guide block 12 is stationary in the guide groove 13, and the dustproof net 18 is installed on one side of the air supply frame 1 for preliminary dust filtration.

[0042] When it is necessary to adjust the angle of the air guide plate 9, the operator connects the small stepper motor 15 to the external power supply, and then starts the small stepper motor 15 in the mounting box 14. The output end of the small stepper motor 15 drives the rotating shaft 16 to rotate. Since one of the gears 7 is fixedly connected to the rotating shaft 16, the gear 7 will start to rotate with the rotating shaft 16.

[0043] Moreover, after the gear 7 connected to the rotating shaft 16 rotates, it drives the lower gear groove plate 6 to move through the meshing relationship. The lower gear groove plate 6 drives the U-shaped frame 4 to slide within the limiting frame 3. The roller 5 at the bottom of the U-shaped frame 4 rolls at the bottom of the limiting frame 3, reducing the friction when the U-shaped frame 4 slides.

[0044] At the same time, the other gears 7 that mesh with the lower gear slot plate 6 also begin to rotate, and these gears 7 drive the rotating rod 8 fixed at one end to rotate.

[0045] When the rotating rod 8 rotates, the air guide plate 9 fixed on the surface of the rotating rod 8 rotates accordingly, thereby realizing the adjustment of the angle of the air guide plate 9. Since the air guide plate 9 is set in an arc shape, it can change the airflow direction and diffusion angle during rotation to meet different air supply needs.

[0046] Meanwhile, during the rotation of gear 7 and the movement of lower gear slot plate 6, upper gear slot plate 10 slides in the groove of fixed frame 2 through L-shaped protrusion 11 and L-shaped guide block 12 slides in guide groove 13, which guides and limits upper gear slot plate 10, ensuring that gear 7, lower gear slot plate 6 and upper gear slot plate 10 always maintain a good meshing relationship, making the transmission process stable and reliable.

[0047] Furthermore, when the small stepper motor 15 is working continuously, the heat dissipation holes on the surface of the mounting box 14 can help the motor dissipate heat and prevent the motor from being affected or damaged due to overheating. When the air-cooled cabinet air conditioner delivers air, the air passes through the air delivery frame 1, is initially filtered by the dust filter 18, and then passes through the air guide plate 9 with the angle adjusted, and is delivered in a specific direction and angle to achieve precise air delivery.

[0048] Since the air guide plate 9 is made of aluminum alloy and has an anti-corrosion layer 17 on its surface, it can be guaranteed to be resistant to corrosion during long-term use and to stably perform its air guiding function.

[0049] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
