DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0022] It should be noted that similar reference numerals and letters represent similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings. In addition, the terms "first," "second," etc. are used only to distinguish the descriptions and are not to be understood as indicating or implying relative importance.

[0023] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0024] In the description of the embodiments of the present invention, it should be noted that the terms "inside", "outside", "upper", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of the present invention is usually placed when in use.

Therefore, they cannot be understood as a limitation on the present invention.

[0025] like Figures 1 to 4 As shown, a central air conditioner maintenance tool mounting device includes a tool box 1. Two connecting rods 2 are movably connected to the surface of the tool box 1. A docking assembly 3 is provided on the top of the tool box 1 for limiting the position of the connecting rods 2. A storage mechanism 6 is provided inside the tool box 1 for easily storing maintenance tools. A sleeve 4 is movably connected to the end of the connecting rod 2. The surface of the sleeve 4 is provided with a locking assembly 5 for connecting to the surface of the central air conditioner. More specifically, the locking assembly 5 is clamped and fixed to the protruding position on the top of the central air conditioner outdoor unit, and the connecting rod 2 is pulled to slide along the surface of the sleeve 4 so that the left side of the tool box 1 is in contact with the surface of the air conditioner outdoor unit. After the tool box 1 is moved up and down to the appropriate height, the connecting rod 2 is positioned using the docking assembly 3 to keep the tool box 1 stable. The maintenance personnel can then take maintenance tools or store small parts from the storage mechanism 6 at the appropriate height.

[0026] The docking assembly 3 includes a fixed frame 301, which is fixedly connected to the top surface of the toolbox 1. A spring 302 is fixedly connected to the inner wall of the fixed frame 301, and a lever 303 is fixedly connected to the free end of the spring 302. An insertion rod 304 is fixedly connected to the left side of the lever 303. A positioning hole 305 is formed through the surface of the connecting rod 2, and the inner wall of the positioning hole 305 is movably connected to the insertion rod 304. It should be noted that by pressing the lever 303, the spring 302 is stretched, causing the insertion rod 304 to disengage from the interior of the positioning hole 305, thereby releasing the restriction on the connecting rod 2. After adjusting the height of the toolbox 1 up or down, the lever 303 is released. The elastic force of the spring 302 will push the lever 303 and the insertion rod 304 to move, so that the insertion rod 304 is inserted into the inner wall of the positioning hole 305, and the toolbox 1 can be repositioned, thereby adjusting the toolbox 1 to the appropriate height.

[0027] There are multiple positioning holes 305, and the multiple positioning holes 305 are evenly spaced on the surface of the connecting rod 2. More specifically, by arranging multiple positioning holes 305 at equal intervals, the tool box 1 can be matched with the insertion rod 304 at different positions to adjust the height of the tool box 1.

[0028] The locking assembly 5 includes a mounting frame 501, which is fixedly connected to the sleeve 4. A stud screw 502 is rotatably connected to the inner wall of the mounting frame 501, and a knob 503 is fixedly connected to the end of the stud screw 502. A slide bar 504 is fixedly connected to the inner wall of the mounting frame 501. A clamping plate 505 is threadedly connected to the surface of the stud screw 502, and the clamping plate 505 is slidably connected to the slide bar 504. It should be noted that by rotating the knob 503, the stud screw 502 is rotated, and the action of the threads drives the clamping plate 505 to slide along the surface of the slide bar 504, thereby clamping and fixing the protruding portion of the top of the central air conditioner outdoor unit.

[0029] The storage mechanism 6 includes a storage box 601 that is movably connected to the left side of the toolbox 1. A ridge 602 is fixedly connected to the surface of the storage box 601. More specifically, by providing multiple storage boxes 601, they can be used to store repair tools and small parts for disassembly and cutting. The ridge 602 facilitates the pulling and pulling of the storage boxes 601. In practice, the storage boxes 601 can be locked to the toolbox 1 using conventional locks, such as a hasp lock, to prevent the storage boxes 601 from accidentally slipping out of the toolbox 1.

[0030] The bottom of the tool box 1 is provided with rollers 7 at the four corners, and a grip 8 is fixedly connected between the two sleeves 4. It should be noted that when carrying, the grip 8 can be grasped by hand and rolled with the rollers 7 to move and carry quickly.

[0031] In summary: clamp and fix the locking component 5 to the protruding position on the top of the central air-conditioning outdoor unit, pull the connecting rod 2 to slide along the surface of the sleeve 4, so that the left side of the tool box 1 fits the surface of the air-conditioning outdoor unit. After moving the tool box 1 up and down to the appropriate height, use the docking component 3 to position the connecting rod 2 so that the tool box 1 remains stable. Maintenance personnel can take maintenance tools or store small parts from the storage mechanism 6 at a suitable height. During use, it is easy to take and switch tools during the maintenance of the central air-conditioning outdoor unit. The tool box can be placed at a suitable height, so that maintenance personnel do not need to repeatedly bend over to use the tool box, making the maintenance process more convenient.

[0032] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions merely illustrate the principles of the present invention. Various changes and improvements are possible without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention. The scope of protection claimed for the present invention is defined by the appended claims and their equivalents.
