Description

Technical Field

[0001] The utility model belongs to the field of air conditioner maintenance, in particular to a portable air conditioner maintenance device. Background Art

[0002] Air conditioning, or air conditioner, refers to equipment that uses manual means to adjust and control parameters such as the temperature, humidity, and flow rate of the ambient air in a building or structure. When the air conditioner needs to be inspected and repaired, staff are required to bring tools to the site to inspect the lines and machines. Since they need to carry more tools, they generally carry a special toolbox, and the maintenance tools are placed in the toolbox. The China Patent Office issued an authorization announcement on July 27, 2021, with the authorization announcement number CN213796422U, a patent entitled "A Portable Central Air Conditioner Inspection and Maintenance Device". The patent discloses a device for classifying maintenance tools, but the device can only be used as a toolbox for storing tools when in use. Considering that there are too many parts to be disassembled and replaced when repairing the air conditioner, they are easy to lose if they are not placed properly, so we designed a portable air conditioner maintenance device.

The utility model has a simple structure and an ingenious design. It can be used not only as a tool box but also as an operating table. When in use, the first fixing plate 6 and the second fixing plate 7 are unfolded to form an operating table, which is convenient for placing tools needed for repairing the air conditioner and parts for disassembly and replacement, and is easy to find and improve work efficiency. When not in use, the first fixing plate 6 and the second fixing plate 7 can be stored on the box body 1 to save space, facilitate transportation, meet market demand, and be suitable for promotion. When using the utility model, first place one side of the box body 1 with the support block 4 flat on a horizontal plane, release the limiting mechanism, open the first fixing plate 6 and the fixing frame 8 in turn, and rotate the second fixing plate 7 to place it above the fixing frame 8. At this time, the first fixing plate 6 and the second fixing plate 7 form an operating table, release the locking mechanism to open the box door 3, take out the required tools from the box body 1, place them on the operating table and work, and also place the disassembled parts on the operating table for convenience of later work. When the maintenance is completed, put the tools back into the box body 1 and lock it with the locking mechanism, rotate the second fixing plate 7 to overlap with the first fixing plate 6, and move the first fixing plate 6 to make the fixing frame 8 accommodated in the box body 1, the first fixing plate 6 abuts against the top side of the box body 1, and is limited by the limiting mechanism. At this time, the box body 1 is rotated so that the side with the rolling wheel 2 touches the ground, and the box body 1 can be easily moved.

[0017] Specifically, as shown in the figure, in this embodiment, two first reinforcing plates 20 are symmetrically fixedly installed on the bottom of the first fixing plate 6, two first fixing blocks 21 are correspondingly fixedly installed on the top of the box body 1, two second reinforcing plates 22 are symmetrically fixedly installed on the inner periphery of the fixing frame 8, and two second fixing blocks 23 are correspondingly fixedly installed on the top of the box body 1. One end of two first connecting rods 24 are respectively hinged on the first reinforcing plate 20, and the other end of the first connecting rod 24 is respectively hinged on the corresponding first fixing block 21, and one end of two second connecting rods 25 are respectively hinged on the second reinforcing plate 22. The other ends of the connecting rods 25 are hinged on the corresponding second fixed blocks 23, and the corresponding inner first connecting rods 24 and the second connecting rods 25 are rotatably connected through the third connecting rods 26, and the other ends of the outer first connecting rods 24 are elastically connected to the corresponding first fixed blocks 21 through spring rods 27. The fixed ends of the spring rods 27 are hinged on the first fixed blocks 21, and the movable ends of the spring rods 27 are hinged on the outer first connecting rods 24. The first fixed blocks 21 and the second fixed blocks 23 are respectively provided with limit blocks 28 for limiting the rotation of the first connecting rods 24 and the second connecting rods 25. When it is necessary to open the first fixing plate 6, the first fixing plate 6 is lifted to the upper right, the first fixing plate 6 drives the first connecting rod 24 to rotate, the spring rod 27 is stretched, the first connecting rod 24 on the inside drives the third connecting rod 26 to rotate, the third connecting rod 26 can drive the second connecting rod 25 on the inside to rotate, so that the second connecting rod 25 can lift the fixing frame 8, when the first connecting rod 24 and the second connecting rod 25 are respectively rotated to abut against the corresponding limit blocks 28, they cannot continue to rotate, and at this time the first fixing plate 6 cannot continue to move outward, the second fixing plate 7 is rotated to the top of the fixing frame 8, and it is in a stable state at this time, and the maintenance tools or disassembled parts can be placed on the top of the first fixing plate 6 and the second fixing plate 7, which is more convenient to use; when use is finished, first rotate the second fixing plate 7 to overlap with the first fixing plate 6, and move the first fixing plate 6 to the lower left to drive the fixing frame 8 to move, and finally the fixing frame 8 is stored in the box body 1, and the first fixing plate 6 abuts against the top side of the box body 1.

[0018] Specifically, as shown in the figure, two second partitions 30 are fixedly provided in the box body 1 in left and right symmetry, the top side of the second partition 30 is in contact with the first partition 5, and the bottom side of the second partition 30 is in contact with the inner wall of the box body 1. The second partition 30 divides the box body 1 into three cavities, which is convenient for classifying maintenance tools and is more convenient to use.

[0019] Further, as shown in the figure, the locking mechanism of this embodiment includes a door lock 40, which is fixedly mounted on the box door 3, and a corresponding groove 41 is provided on the box body 1. The box door 3 can be locked by rotating the paddle of the door lock 40 into the groove 41 using a key to prevent the tool from falling out of the box body 1 when moving.

[0020] Furthermore, as shown in the figure, the limiting mechanism of this embodiment includes a threaded rod 50, and a slide groove 51 is respectively provided on the first fixing plate 6 and the second fixing plate 7. The threaded rod 50 is slidably installed in the slide groove 51. The box body 1 is provided with a threaded hole 52, and the threaded rod 50 is threadedly engaged with the threaded hole 52. A stopper 53 is fixedly installed at one end of the threaded rod 50. The second fixing plate 7 is rotated to overlap with the first fixing plate 6, and the threaded rod 50 is inserted into the slide groove 51 and is tightened on the box body 1 through threaded engagement, so that the stopper 53 is in contact with the second fixing plate 7, and the first fixing plate 6 and the second fixing plate 7 can be limited at this time.

[0021] Furthermore, as shown in the figure, in this embodiment, a handle 60 is fixedly installed on one side of the box body 1 and the box door 3. Pulling the box body 1 or opening the box door 3 through the handle 60 is more convenient and labor-saving.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the utility model.
