[0015] Beneficial effects

[0016] The utility model provides an auxiliary tool for central air-conditioning detection and maintenance. Compared with the prior art, the following beneficial effects are achieved:

[0017] (1). For the auxiliary tool for central air-conditioning detection and maintenance, by designing a lifting and adjusting mechanism, the detection and maintenance personnel can directly rotate the lifting screw rod through the rotating wheel. Since the lifting screw rod is threadedly connected with the workbench, the workbench will rise and fall with the rotation of the lifting screw rod. At the same time, the gears on the two coupling shafts rotate synchronously through the transmission chain, ensuring that the lifting screw rods on both sides can rise and fall synchronously and guaranteeing the stable lifting of the workbench.

[0018] (2). For the auxiliary tool for central air-conditioning detection and maintenance, by designing an auxiliary support component, the auxiliary support component is fixed to the lower surface of the workbench through the support plate, and the connecting block is movably installed through the movable shaft rod. When the workbench rises and falls, the transmission component converts the rotational movement of the coupling shaft into the rotational movement of the pushing screw rod through the meshing transmission of the first bevel gear and the second bevel gear. The pushing screw rod cooperates with the threaded block to push the threaded block to move horizontally, and then realizes the auxiliary support for the workbench through the movable support structure composed of the support plate, the movable shaft rod and the connecting block, that is, the support plate rises and falls synchronously with the workbench.

Detailed implementation manners

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0025] Please refer to Figures 1-4 , the present utility model provides a technical solution: an auxiliary tool for central air-conditioning detection and maintenance, including a bottom plate 1 and an operating table 3. A lifting and adjusting mechanism 2 is provided between the bottom plate 1 and the operating table 3. The lifting and adjusting mechanism 2 includes:

[0026] A lifting assembly 21, disposed on the upper part of the bottom plate 1, including two groups of coupling shafts 213 rotatably installed on the bottom plate 1. The upper ends of the two groups of coupling shafts 213 are welded with a lifting screw rod 211, and the top end of the lifting screw rod 211 is welded with a rotating wheel handle 212. The lower ends of the coupling shafts 213 are welded with gears 214, and a transmission chain 215 is drivenly connected to the gears 214, so that the gears 214 on the two groups of coupling shafts 213 can rotate synchronously. The lifting screw rod 211 penetrates through the operating table 3 and is threadedly connected thereto;

[0027] An auxiliary support assembly 22, disposed on the lower part of the operating table 3 and used for auxiliary support of the operating table 3;

[0028] A transmission component 23, disposed on the lower part of the auxiliary support assembly 22 and used for pushing the auxiliary support assembly 22 to move up and down.

[0029] In this embodiment, the auxiliary support assembly 22 includes a support plate 221 fixed to the lower surface of the workbench 3. At the lower ends on both sides of the support plate 221, connection blocks 223 are movably installed through movable shaft rods 222. A U-shaped rod 224 is fixed to one side of the connection block 223, and a threaded block 225 is fixed to the lower end of the U-shaped rod 224. The transmission assembly 23 includes a first bevel gear 231 welded to the outer wall of the coupling shaft 213. A base block 234 is fixed to the upper end of the bottom plate 1. A push rod 233 is rotatably installed on the base block 234 near the first bevel gear 231. The push rod 233 passes through the threaded block 225 and is threadedly connected thereto. A second bevel gear 232 that meshes and drives with the first bevel gear 231 is welded to the end of the push rod 233. Through the meshing drive of the first bevel gear 231 and the second bevel gear 232, the transmission assembly 23 converts the rotational motion of the coupling shaft 213 into the rotational motion of the push rod 233. The push rod 233 cooperates with the threaded block 225 to push the threaded block 225 to move horizontally, and then realizes the auxiliary support for the workbench 3 through the movable support structure composed of the support plate 221, the movable shaft rod 222, and the connection block 223.

[0030] In this embodiment, a pushing caster is installed at the bottom end of the bottom plate 1, and a safety guardrail is installed at the upper end of the workbench 3. The pushing caster installed at the bottom end of the bottom plate 1 facilitates the movement of the entire auxiliary tool, and the safety guardrail installed at the upper end of the workbench 3 can ensure the personal safety of the operators during inspection and maintenance.

[0031] Meanwhile, the content not described in detail in this specification belongs to the well-known prior art in the art.

[0032] During operation, the inspection and maintenance personnel first rotate the 212 rotating lifting screw 211 through a runner. Since the lifting screw 211 is threadedly connected to the operating table 3, the operating table 3 will rise and fall with the rotation of the lifting screw 211. At the same time, the gears 214 on the two groups of couplings 213 rotate synchronously through the transmission chain 215 to ensure that the lifting screws 211 on both sides can rise and fall synchronously, ensuring the stable lifting of the operating table 3. The auxiliary support assembly 22 is fixed to the lower surface of the operating table 3 through the support plate 221, and the connecting block 223 is movably installed through the movable shaft rod 222. When the operating table 3 rises and falls, the transmission assembly 23 converts the rotational movement of the coupling 213 into the rotational movement of the extension screw 233 through the meshing transmission of the first bevel gear 231 and the second bevel gear 232. The extension screw 233 cooperates with the threaded block 225 to push the threaded block 225 to move horizontally, and then realizes the auxiliary support for the operating table 3 through the movable support structure composed of the support plate 221, the movable shaft rod 222 and the connecting block 223, that is, the support plate 221 rises and falls synchronously with the operating table 3. In addition, the push casters installed at the bottom end of the bottom plate 1 facilitate the movement of the entire auxiliary tool, and the safety guardrail installed at the upper end of the operating table 3 can ensure the personal safety of the operators during inspection and maintenance.
