Description

Technical Field

[0001] This utility model relates to the field of air conditioner testing, and more specifically, to a workbench for air conditioner testing. Background Technology

[0002] An air conditioner, or air conditioner, is a device that regulates and controls parameters such as temperature, humidity, and airflow of the air inside a building or structure. A typical household air conditioner consists of an outdoor unit and an indoor unit. Air conditioners undergo multiple tests during the production process, and after production, they must be tested again before they can be packaged and sold.

[0003] In the prior art, Chinese utility model patent with announcement number CN218082340U discloses a workbench for air conditioner testing. It uses the gravity of the air conditioner outdoor unit to press down the slide plate, and through the linkage component, drives four radially arranged clamping plates to move inward synchronously to clamp the outdoor unit. At the same time, the edge of the slide plate pushes the slider to move outward. After the slide plate passes, the slider is reset under the action of the spring and is locked at the top of the slide plate to form a self-locking mechanism, thereby realizing the rapid fixing of outdoor units with different shapes.

[0004] However, in actual use, the existing technology uses a slider to lock the outdoor unit in place after it is fixed on the slide plate. After the outdoor unit is inspected and removed, the slider remains stuck at the top of the slide plate and cannot automatically detach due to the spring limit. The slide plate also cannot automatically reset on its own. At this point, the handles on both sides must be manually pulled to overcome the spring force and move the slider away from the slide plate. Only after the limit is released can the slide plate return to its initial state. This extra manual reset step not only increases the operation process and prolongs the overall time of a single outdoor unit inspection, but also increases the labor intensity of the operators due to the repetitive manual operation. It is difficult to adapt to the needs of efficient and automated modern air conditioning production and inspection. In view of this, we propose an air conditioning inspection workbench to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inconvenience in using some current air conditioning testing workbenches.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a workbench for air conditioner testing, including a base. A movable frame is slidably disposed inside the base. A placement frame is hinged inside the movable frame. A placement plate is slidably disposed inside the placement frame. A third spring is fixedly connected between the lower surface of the placement plate and the bottom wall of the placement frame. Four positioning mechanisms are disposed on the upper side of the placement plate. Four locking blocks are slidably connected inside the placement frame. A groove is formed on the upper surface of the placement plate. A first L-shaped connecting plate is movably disposed inside the groove.

[0009] As a preferred technical solution of this application, the reset mechanism includes a guide rod, which is fixedly connected to the upper surface of the placement frame. The second L-shaped connecting plate is slidably sleeved on the outside of the guide rod, and a first spring is fixedly connected between the lower surface of the second L-shaped connecting plate and the upper surface of the placement frame.

[0010] As a preferred technical solution of this application, a first connecting ear is fixedly connected to the lower surface of the card block, and a second spring is fixedly connected between the first connecting ear and the surface of the placement frame.

[0011] As a preferred technical solution of this application, the positioning mechanism includes a fixed column, an inclined plate is hinged between the fixed column and the placement plate, a telescopic column is slidably sleeved inside the fixed column, a clamping plate is fixedly connected to one end of the telescopic column, a threaded rod is rotatably connected inside the fixed column, and the telescopic column is threadedly sleeved on the outside of the threaded rod.

[0012] As a preferred technical solution of this application, the surface of the fixing column is provided with a through groove, and the smooth section of the threaded rod is fixedly fitted with a knob, which extends out of the outside of the fixing column through the through groove.

[0013] As a preferred technical solution of this application, a second connecting ear is fixedly connected to both sides of the fixed column, and a limiting rod is slidably sleeved inside the second connecting ear, and the limiting rod is fixedly connected to the inner wall of the placement frame.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. Through the cooperation of the first L-shaped connecting plate, the second L-shaped connecting plate, the trapezoidal block, the contact rod, the locking block, the second spring, and the third spring, when the outdoor unit of the air conditioner is detected and lifted upwards, the first spring automatically drives the trapezoidal block to move upwards, the trapezoidal block pushes the locking block to slide outwards to release the lock on the placement plate, and the third spring then pushes the placement plate to reset. At the same time, the inclined plate drives the clamping plate to automatically release the outdoor unit. There is no need to manually pull any handle or perform any additional unlocking steps, which greatly reduces the operation process, reduces labor intensity, and significantly improves the efficiency of picking and placing the outdoor unit of the air conditioner. 2. Through the coordination of the fixed columns, telescopic columns, threaded rods, knobs, and inclined plates, the operator can adjust the extension length of the telescopic columns in advance according to the actual specifications of the air conditioner outdoor unit by turning the knobs, thereby changing the initial radial position of the four clamping plates. Precise adjustments can be achieved by using the scale markings on the surface of the telescopic columns, allowing the workbench to adapt to air conditioner outdoor units of different widths without replacing any parts. This significantly improves the versatility and flexibility of the equipment, solves the problem of poor specification adaptability in existing technologies, and meets diverse production and testing needs.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0018] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0019] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0020] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0021] Please refer to Figures 1-5 An air conditioner testing workbench includes a base 1, a movable frame 2 slidably disposed inside the base 1, a placement frame 3 hinged inside the movable frame 2, a placement plate 4 slidably disposed inside the placement frame 3, a third spring 25 fixedly connected between the lower surface of the placement plate 4 and the bottom wall of the placement frame 3, four positioning mechanisms disposed on the upper side of the placement plate 4 (since the four positioning mechanisms have the same structure, the following description focuses on one positioning mechanism), four locking blocks 5 slidably connected inside the placement frame 3 (all four locking blocks 5 are U-shaped), a groove 6 is formed on the upper surface of the placement plate 4, a first L-shaped connecting plate 7 is movably disposed inside the groove 6, a connecting mechanism is disposed at the upper end of the first L-shaped connecting plate 7, and a transmission mechanism is disposed on the surface of the locking blocks 5.

[0022] The thickness of the horizontal plate of the first L-shaped connecting plate 7 is the same as the thickness of the groove 6, thereby ensuring the flatness of the upper surface of the plate 4 after the first L-shaped connecting plate 7 is embedded in the groove 6.

[0023] In the above embodiments, the base 1 is also provided with a drive device for moving the movable frame 2 laterally, thereby detecting whether there are loose parts inside the air conditioner outdoor unit. The movable frame 2 is provided with a drive device for tilting the placement frame 3, so as to improve the detection effect of the air conditioner outdoor unit. Since these are all publicly known technical means known to those skilled in the art, please refer to the prior art with announcement number CN218082340U for details. Therefore, they will not be described in detail here.

[0024] Furthermore, such as Figures 1-5 As shown, the connecting mechanism includes a second L-shaped connecting plate 8, which is fixed to the upper end of the first L-shaped connecting plate 7. A trapezoidal block 9 is fixedly connected to the lower end of the second L-shaped connecting plate 8, and a reset mechanism is provided on the upper surface of the placement frame 3.

[0025] Thus, when the outdoor unit of the air conditioner is placed on the placement plate 4, it will press the first L-shaped connecting plate 7 into the groove 6, thereby forcing the placement plate 4 and the first L-shaped connecting plate 7 to move downwards synchronously, which in turn drives the second L-shaped connecting plate 8 and the trapezoidal block 9 to move downwards. At this time, the third spring 25 will deform.

[0026] Furthermore, such as Figures 1-5 As shown, the transmission mechanism includes two fixed plates 12, both of which are fixedly connected to the upper surface of the locking block 5, and a contact rod 13 is rotatably connected between the two fixed plates 12.

[0027] Thus, when the second L-shaped connecting plate 8 and trapezoidal block 9 move downwards, trapezoidal block 9 will naturally come into contact with contact rod 13. Guided by the inclined surface of trapezoidal block 9, contact rod 13, fixing plate 12 and locking block 5 will be forced to move outwards. When the placement plate 4 moves to the lower side of the horizontal height of locking block 5, the other inclined surface of trapezoidal block 9 will come into contact with contact rod 13, thereby causing locking block 5 to reset. At this time, locking block 5 will be locked on the upper side of placement plate 4, thereby restricting placement plate 4.

[0028] Furthermore, such as Figures 1-5 As shown, the reset mechanism includes a guide rod 10, which is fixedly connected to the upper surface of the placement frame 3. A second L-shaped connecting plate 8 is slidably sleeved on the outside of the guide rod 10. A first spring 11 is fixedly connected between the lower surface of the second L-shaped connecting plate 8 and the upper surface of the placement frame 3.

[0029] Thus, when the second L-shaped connecting plate 8 moves downward, the first spring 11 will deform, so that after the air conditioner outdoor unit is removed, the first L-shaped connecting plate 7 will no longer be pressed down. Therefore, under the action of the first spring 11, the first L-shaped connecting plate 7 will be driven to reset. At this time, the first L-shaped connecting plate 7, the second L-shaped connecting plate 8, and the trapezoidal block 9 will all move upward. At this time, with the cooperation of the trapezoidal block 9, the contact rod 13, and the fixing plate 12, the locking block 5 will first be driven to slide outward a certain distance. At this time, the locking block 5 will no longer be located on the upper side of the placement plate 4. Then, under the action of the third spring 25, the placement plate 4 will reset, and the staff will no longer need to pull the locking block 5 through the external handle, thus realizing the automatic reset of the placement plate 4.

[0030] Furthermore, such as Figures 1-5As shown, a first connecting ear 14 is fixedly connected to the lower surface of the card block 5, and a second spring 15 is fixedly connected between the first connecting ear 14 and the surface of the placement frame 3.

[0031] Thus, when the locking block 5 slides outward, the second spring 15 will produce a corresponding elastic deformation, so as to assist the locking block 5 in resetting under the action of the second spring 15.

[0032] Furthermore, such as Figures 1-5 As shown, the positioning mechanism includes a fixed column 16, an inclined plate 17 is hinged between the fixed column 16 and the placement plate 4, a telescopic column 18 is slidably sleeved inside the fixed column 16, and the surface of the telescopic column 18 is provided with scale markings, one end of the telescopic column 18 is fixedly connected to a pressing plate 19, and the surface of the pressing plate 19 is provided with a rubber pad, a threaded rod 20 is rotatably connected inside the fixed column 16, and the telescopic column 18 is threadedly sleeved on the outside of the threaded rod 20.

[0033] Furthermore, such as Figures 1-5 As shown, a through groove 22 is provided on the surface of the fixed post 16, and a knob 21 is fixedly sleeved on the smooth section of the threaded rod 20. The knob 21 extends out of the outside of the fixed post 16 through the through groove 22.

[0034] Thus, by turning the knob 21 with the operator's finger, the threaded rod 20 can be rotated. The rotation of the threaded rod 20 can cause the telescopic column 18 to slide inside the fixed column 16, thereby changing the initial position of the clamping plate 19. This allows the operator to adjust the position of each clamping plate 19 according to the specifications of the air conditioner outdoor unit, thereby improving the flexibility and versatility of the device.

[0035] Furthermore, such as Figures 1-5 As shown, the two sides of the fixed column 16 are fixedly connected with second connecting ears 23, and the inside of the second connecting ears 23 is slidably fitted with a limiting rod 24, which is fixedly connected to the inner wall of the placement frame 3.

[0036] Thus, when the placement plate 4 moves downward under force, since the fixed column 16 is fixed in position and the fixed column 16 and the placement plate 4 are hinged by the inclined plate 17, the fixed column 16, the telescopic column 18 and the clamping plate 19 will be pulled to move, and finally the positioning and clamping of the air conditioner outdoor unit will be achieved.

[0037] The usage process of the air conditioner testing workbench provided by this utility model is as follows: First, according to the specifications and dimensions of the outdoor unit of the air conditioner to be tested, the extension length of the telescopic column 18 is adjusted by the knob 21 in each positioning mechanism. The operator rotates the knob 21 with their finger, and the knob 21 drives the threaded rod 20 to rotate. Since the telescopic column 18 is threaded on the outside of the threaded rod 20, the rotation of the threaded rod 20 forces the telescopic column 18 to slide along the inside of the fixed column 16, thereby changing the initial radial position of the clamping plate 19. With the help of the scale markings on the surface of the telescopic column 18, the clamping range in four directions can be precisely adjusted to adapt to outdoor units of different widths.

[0038] After pre-adjustment, the outdoor unit of the air conditioner is placed into the placement frame 3 from top to bottom. The bottom of the outdoor unit first contacts the four first L-shaped connecting plates 7 and presses the first L-shaped connecting plates 7 downward into the groove 6. At the same time, the placement plate 4 begins to slide downward under the weight of the outdoor unit, and the third spring 25 is compressed. When the first L-shaped connecting plate 7 moves down, it drives the second L-shaped connecting plate 8 and the trapezoidal block 9 fixed to it to move downward synchronously. The second L-shaped connecting plate 8 slides along the guide rod 10 and causes the first spring 11 to deform. During the downward movement of the trapezoidal block 9, its inclined surface first contacts the contact rod 13. Under the guidance of the inclined surface, the contact rod 13 drives the fixing plate 12 and the locking block 5 to slide outward. The second spring 15 is stretched through the first connecting ear 14. When the placement plate 4 continues to move down to the horizontal height of the locking block 5, the other inclined surface of the trapezoidal block 9 disengages from the contact rod 13. At this time, under the reset action of the second spring 15, the locking block 5 resets inward and locks onto the upper surface of the placement plate 4, thereby locking the placement plate 4 and preventing it from moving upward.

[0039] Meanwhile, when the placement plate 4 moves down, the fixed column 16 (slidably constrained by the second connecting ear 23 and the limiting rod 24) is relatively fixed, and the fixed column 16 and the placement plate 4 are respectively hinged at both ends of the inclined plate 17. Therefore, the downward movement of the placement plate 4 will pull the four fixed columns 16 and the telescopic columns 18 and the clamping plate 19 on them to move synchronously towards the center through the inclined plate 17. Finally, the clamping plate 19 clamps the air conditioner outdoor unit from four directions, completing the rapid positioning. Then, the bottom drive mechanism can be started to drive the moving frame 2 to move laterally back and forth, or the angle of the placement frame 3 can be adjusted by the tilting mechanism to detect abnormal noise.

[0040] After the inspection is completed, the staff lifts the outdoor unit of the air conditioner upwards. As the bottom of the outdoor unit leaves the placement plate 4, it continues to press down on the first L-shaped connecting plate 7 for a period of time. However, as the outdoor unit is lifted, the pressure on the first L-shaped connecting plate 7 gradually decreases. At this time, the first spring 11 begins to reset, driving the second L-shaped connecting plate 8, the trapezoidal block 9, and the first L-shaped connecting plate 7 to move upwards. During the upward movement of the trapezoidal block 9, its inclined surface contacts the contact rod 13 again, pushing the locking block 5 to slide outwards, causing the locking block 5 to disengage from the upper surface of the placement plate 4. After the locking block 5 is unlocked, the compressed third spring 25 releases its elasticity, pushing the placement plate 4 to reset upwards. At the same time, the inclined plate 17 pulls the clamping plate 19 to release the outdoor unit outwards. When the first L-shaped connecting plate 7 is completely reset, the locking block 5 resets inwards again under the action of the second spring 15, waiting for the next working cycle. The entire removal process does not require manual operation of any unlocking handle, realizing the automatic reset of the placement plate 4 and each clamping plate 19.
