[0008] Preferably, a corner guard is fixedly installed on the side of the tool carrying box away from the material receiving box, and the dual-axis motor and the connecting shaft are both located in the inner wall of the corner guard.

[0009] Preferably, a longitudinal slide groove is provided through the top of the adjustment frame, and the bottom ends of the two groups of mounting rods are T-shaped structures.

[0010] Preferably, the bottom ends of the two groups of mounting rods slide in the inner walls of the longitudinal sliding grooves respectively.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0022] See also Figure 1-4 The utility model provides a technical solution: a tool mounting device for central air conditioning maintenance, comprising a tool carrying box 1 and a mounting rod 4. A material receiving box 2 is rotatably connected to one side of the top of the tool carrying box 1 through a damping shaft. An adjustment frame 3 is movably installed on the top of the tool carrying box 1. One end of the adjustment frame 3 is rotatably connected to a longitudinal screw rod 32. The bottom ends of two sets of mounting rods 4 are respectively connected to the outside of the longitudinal screw rod 32 through threaded cooperation.

[0023] The front and back sides of the tool carrier box 1 are rotatably connected with transverse screw rods 5, respectively. The ends of the adjustment frame 3 are threadedly mounted on the outside of the transverse screw rods 5 on the same side. One end of the two sets of transverse screw rods 5 is fixedly mounted with first bevel gears 51. A dual-axis motor 7 is fixedly mounted on the side of the tool carrier box 1 away from the receiving box 2. A connecting shaft 71 is fixedly connected to the output end of the dual-axis motor 7. Second bevel gears 72 are fixedly mounted on both ends of the connecting shaft 71. The outer edges of the two sets of second bevel gears 72 are respectively meshed with the outer edges of the first bevel gears 51 on the same side.

[0024] The tool carrying box 1 can be mounted on the built-in square inspection port of the central air conditioner through two sets of L-shaped mounting rods 4. The inclined surface on one side of the tool carrying box 1 can reduce the area occupied by the tool carrying box 1. The two sets of L-shaped mounting rods 4 can adjust the spacing through the transverse screw rods 5, so that the two sets of mounting rods 4 can be hung on square inspection ports of different sizes. The use of the central air conditioner maintenance tool mounting rod 4 is a prior art and will not be described in detail here.

[0025] The second bevel gears 72 at both ends of the connecting shaft 71 are driven by the dual-axis motor 7 to drive the first bevel gear 51 meshed at the end, so that the two sets of transverse screw rods 5 can rotate synchronously in the transverse slide groove 11, so that the bottom ends of the two sets of mounting rods 4 can slide to the other side along the transverse slide groove 11. In this way, when the tool box is mounted at the inspection port, the mounting rod 4 can be adjusted to the side of the inspection port away from the maintenance personnel, thereby avoiding the mounting rod 4 from blocking the tool taking position, which makes it inconvenient for the maintenance personnel to take the tools inside the tool box;

[0026] The receiving box 2 which rotates through the damping shaft on the top of the tool carrier box 1 close to the maintenance personnel can collect the maintenance residues at the maintenance opening on the maintenance personnel's side to prevent them from falling below and into the tool box.

[0027] Among them, a corner guard bar 6 is fixedly installed on the side of the tool carrying box 1 away from the material receiving box 2, the dual-axis motor 7 and the connecting shaft 71 are both located in the inner wall of the corner guard bar 6, the two ends of the adjusting frame 3 are L-shaped structures, and the bottom ends of the two groups of adjusting frames 3 slide in the corresponding inner walls of the horizontal slide groove 11 respectively, and the second bevel gear 72 at both ends of the connecting shaft 71 is driven by the dual-axis motor 7 to drive the first bevel gear 51 engaged at the transmission end, so that the two groups of horizontal screw rods 5 can rotate synchronously in the horizontal slide groove 11, so that the bottom ends of the two groups of mounting rods 4 can slide to the other side along the horizontal slide groove 11. In this way, when the tool box is mounted at the inspection port, the mounting rod 4 can be adjusted to the side of the inspection port away from the maintenance personnel, thereby avoiding the mounting rod 4 from blocking the tool picking position.

[0028] Among them, a longitudinal slide groove 31 is opened through the top of the adjustment frame 3, and the bottom ends of the two groups of mounting rods 4 are T-shaped structures. The bottom ends of the two groups of mounting rods 4 slide in the inner walls of the longitudinal slide groove 31 respectively, and transverse slide grooves 11 are opened on the front and back of the tool carrying box 1 respectively. The two groups of L-shaped mounting rods 4 can adjust the spacing through the transverse screw rod 5, so that the two groups of mounting rods 4 can be hung on square inspection ports of different sizes.

[0029] Working principle: When in use, the distance between the two sets of L-shaped mounting rods 4 can be adjusted according to the size of the inspection opening, and the distance can be adjusted by the transverse screw rod 5, so that the two sets of mounting rods 4 can be hung at square inspection openings of different sizes;

[0030] Then, the double-axis motor 7 can be controlled by the control switch on the back of the tool carrier box 1, and the double-axis motor 7 drives the second bevel gears 72 at both ends of the connecting shaft 71 to drive the first bevel gear 51 that is meshed at the end, so that the two sets of transverse screw rods 5 can rotate synchronously in the transverse slide groove 11, so that the bottom ends of the two sets of mounting rods 4 can slide to the other side along the transverse slide groove 11, so that when the tool box is mounted at the inspection port, the mounting rods 4 can be adjusted to the side of the inspection port away from the maintenance personnel;

[0031] Then hang the tool carrying box 1 on the square inspection opening through two sets of L-shaped mounting rods 4;

[0032] When inspecting the central air-conditioning inspection port, the receiving box 2 which rotates through the damping shaft at the top of the tool carrier box 1 close to the inspector's side can collect the maintenance residues at the inspection port on the inspector's side to prevent them from falling below and into the tool box.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
