Description

Technical Field

[0002] The automatic telescopic ladder for electrical installation is a tool designed specifically for the power, communications and other industries. It has retractable and insulating properties and can provide safe and reliable support for aerial operations.

[0003] The patent publication number CN113148918A discloses an automatic telescopic ladder device for electrical installation and a working method thereof. The third motor drives the two first gears to rotate, and the two first gears drive the first screw rod to rotate. The rectangular plate starts to move along with the two moving blocks, and the large automatic lifting push rod is started. The large automatic lifting push rod pushes the mounting plate until the mounting plate is at a right angle to the bottom plate. The user stands on the rising platform and starts the fourth motor. The fourth motor drives the second screw rod to rotate, and the second screw rod drives the rising platform to move up and down, so as to achieve selective height increase according to needs and facilitate the use of installers.

[0004] The above-mentioned automatic telescopic ladder device can only lift the installer to a certain installation height. Since the size of the equipment to be installed by the installer is not fixed, when it is necessary to install electrical equipment with a large volume and weight, such as air-conditioning equipment, the installer needs to carry the air-conditioning equipment with him when he stands on the ascending platform. Due to the large volume and weight of the air-conditioning equipment, the installer is prone to lose his center of gravity when carrying it up, resulting in the risk of falling during the ascending and installation process. Therefore, there is a safety risk for the installer during the operation, and the air-conditioning equipment may fall and be damaged.

[0005] In addition, when the installers install the air-conditioning equipment against the wall, due to the large mass of the air-conditioning equipment, the air-conditioning equipment will be in rigid contact with the wall, causing wear on the outer casing of the air-conditioning equipment. At the same time, due to the collision of the air-conditioning equipment, the wall plaster layer on the wall surface will be damaged, thus affecting the appearance of the wall surface.

[0016] The present invention also provides a working method of an automatic telescopic ladder device for electrical installation, the purpose of which is to replace manual work to limit the air-conditioning equipment while lifting it to a certain installation height, thereby reducing the labor burden of the installers and the risk of falling of personnel and equipment.

[0017] To achieve the above object, the present invention provides the following technical solution: a working method of an automatic telescopic ladder device for electrical installation, comprising the following steps:

[0018] First, place the air conditioner with mounting on the bearing plate. Under the action of the air conditioner's own gravity, the bearing plate will sink, and then the slider 1 will slide in the wire groove 1. As the slider 1 moves, the half tooth will rotate around the hinge point between it and the hinge groove as the axis.

[0019] When the half teeth rotate, driven by the half teeth, gear one will rotate, and then gear two will move synchronously with gear one. At this time, gear two will drive the rack to move linearly along the guide groove in the fixed block. At this time, the two racks will drive the straight rod and the push plate to approach each other, and then push the transverse moving part to contact with both sides of the air-conditioning equipment. At this time, the transverse moving part will limit the two sides of the air-conditioning equipment under the drive of the blocking part;

[0020] Then the installer stands on the working platform and starts the hydraulic rod. At this time, the piston end of the hydraulic rod extends, and then the lifting frame will be unfolded under the push of the piston end of the hydraulic rod. At this time, the working platform will be lifted to a fixed height;

[0021] At this time, the height of the air-conditioning equipment being lifted and lowered still deviates from the preset installation position. By starting the motor, the motor output shaft will drive gear four, so that gear four drives gear three to rotate, and gear three will rotate the nut synchronously during the rotation process. Since the screw rod is fixedly connected to the lifting plate, when the nut rotates, the screw rod will move linearly along the center axis of the nut, thereby making the lifting plate, the carrying plate, and the air-conditioning equipment arranged on the carrying plate move upward along the center axis of the nut under the pushing action of the screw rod, so that the air-conditioning equipment can be fine-tuned to the preset air-conditioning equipment installation position height;

[0022] When the lifting assembly lifts the air conditioner to the preset installation position, the air conditioner will drive the longitudinal moving plates in the transverse moving parts on both sides to move linearly along the second slide groove during the movement of the air conditioner. At this time, the rolling ball set in the top ball groove will be pushed to move in the direction of the installation groove, and then the installation rod will drive the driving block to move in the direction of the transverse moving plate. During the movement, the driving block will force the avoidance block to move linearly along the elastic groove and avoid the driving block. At this time, the spring 1 is compressed and deformed;

[0023] During the movement of the avoidance block, the roller arranged at one end of the push rod will slide down into the avoidance groove under the push of the second spring. At this time, the end of the push rod away from the roller will be separated from the fixed hole in the guide plate. At this time, the traverse plate can slide linearly along the first wire groove, and the air-conditioning equipment is gradually pushed to the preset installation position close to the wall by pushing the air-conditioning equipment.

[0024] When the blocking component drives the transverse moving component to limit the position of the air-conditioning device, the push plate will drive the pull rod and the plug plate to move synchronously, so that the gas inside the plug cylinder is introduced into the air cushion through the second air guide pipe under the push of the plug plate. At this time, the air cushion will be inflated and expanded. When the air-conditioning device is gradually withdrawn to be close to the wall, the air cushion will contact the wall first, so that the installer can avoid excessive thrust on the air-conditioning device when pushing the air-conditioning device, resulting in rigid contact between the air-conditioning device and the wall, thereby causing wear of the air-conditioning device shell and damage to the wall;

[0025] When the air-conditioning equipment is pushed, since the air guide pipe 1 is connected with the air outlet groove, the air cushion is squeezed when it contacts the wall, causing the gas to flow back into the plug cylinder through the air guide pipe 2. Since the plug plate cannot move under the action of the push plate at this time, the gas is guided to the air outlet groove through the air guide pipe 1. In the process of the air-conditioning equipment being pushed, with the movement of the transverse plate, the air outlet groove will gradually be exposed, causing the gas in the air cushion to be slowly discharged through the air outlet groove. At this time, the air cushion will be deflated, causing the air-conditioning equipment to contact the wall at the preset installation position stably. At this time, the air-conditioning equipment can be fixedly installed on the wall.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The load-bearing plate is sunk by the weight of the air-conditioning equipment itself, so that the half-tooth drive gear 1 and gear 2 rotate, so that the rack moves along the guide groove under the drive of gear 2, and then the two racks drive the two push plates to approach each other, so that the transverse moving component contacts the side of the air-conditioning equipment, and the air-conditioning equipment is limited, so as to avoid damage to the air-conditioning equipment caused by accidental slipping during the lifting process, further avoiding the process that the installer needs to carry the air-conditioning equipment by hand during the lifting process, and further avoiding the high-altitude fall caused by the unstable center of gravity during the high-altitude operation of the installer, thereby improving the personal safety of the installer during the high-altitude operation and reducing the occurrence of safety accidents;

[0028] 2. When the traverse component contacts the air conditioner, the traverse plate and the guide plate are in a locked state, thereby improving the stability of the air conditioner placed on the load-bearing plate and during the rising process. When the lifting assembly lifts the lifting plate and fine-tunes the installation position of the air conditioner, the locking state between the traverse plate and the guide plate will be automatically unlocked. At this time, you only need to manually push the air conditioner, and the traverse plate will slide along the linear track on the guide plate, so that the air conditioner is stably close to the wall, which improves the stability of the air conditioner during installation and improves the installation efficiency.

[0029] 3. In the process of limiting the air-conditioning equipment by the blocking component, the plug plate will move in the plug tube under the pull of the pull rod, and then compress the gas in the plug tube into the air cushion. The air cushion that is introduced with gas will expand. When pushing the air-conditioning equipment to fit the wall, the air cushion will contact the wall first. At this time, the transverse plate and the guide plate are misaligned, and the air outlet groove is exposed. After the air cushion is subjected to the extrusion force, the gas will be quantitatively discharged from the air outlet groove through the air guide pipe 1 and the air guide pipe 2, so that the air cushion can buffer the process of gradual fitting of the air-conditioning equipment and the wall, avoid rigid contact when the air-conditioning equipment and the wall are fitted, avoid wear on the outer casing of the air-conditioning equipment, and at the same time protect the wall surface from damage, thereby improving the aesthetics of the wall surface after installation.

[0048] The features and exemplary embodiments of various aspects of the present invention will be described in detail below.

In the accompanying drawings and the following description, known structures and technologies are not shown to avoid unnecessary ambiguity to the present invention. Example 1

[0050] The lifting assembly 1 includes two bottom plates 12, which are U-shaped structures. The two bottom plates 12 are symmetrically arranged up and down, a lifting frame 13 arranged between the two bottom plates 12, and a hydraulic rod 14 arranged at the lower end of the lifting frame 13. The piston end of the hydraulic rod 14 is hinged with the upper end of the lifting frame 13. The hydraulic rod 14 is used to drive the lifting frame 13 to retract and extend, thereby lifting the working platform 11 to a fixed height;

[0051] The blocking component 2 includes support plates 21 arranged on both sides of the working platform 11, a lifting plate 22 arranged between the two support plates 21, both ends of the lifting plate 22 are clamped with one end of the support plate 21 away from the working platform 11, a bearing plate 23 arranged on the side of the lifting plate 22 away from the working platform 11, and elastic sheets arranged on both sides of a side of the bearing plate 23 close to the lifting plate 22, one end of the elastic sheet away from the bearing plate 23 is connected to the lifting plate 22, and under the support of the elastic sheet, when no electrical equipment is placed on the bearing plate 23, the elastic sheet will lift the bearing plate 23, and the bearing plate 23 is provided. A wire groove 1 is arranged on both sides of one side of the load-bearing plate 23 close to the lifting plate 22, a slider 1 is slidably arranged in the wire groove 1, hinge grooves 221 are arranged at the four corners of the lifting plate 22, and a half tooth 24 is arranged in the hinge groove 221. The half tooth 24 is hingedly matched with the slider 1 at one end away from the hinged connection with the hinge groove 221. When a heavy object is placed on the load-bearing plate 23, the elastic sheet will be deformed and make the load-bearing plate descend toward the lifting plate 22. At this time, the slider 1 will slide in the wire groove 1, so that the half tooth 24 can rotate around the hinged connection with the hinge groove 221.

[0052] The blocking component 2 also includes a support arranged on both sides of the lifting plate 22 away from the bearing plate 23, and a shaft is rotatably mounted on the support, a gear 25 is arranged at both ends of the shaft, and the gear 25 is meshed with the teeth on the outer side of the half tooth 24, and a gear 26 is arranged on both sides of the shaft, and the gear 26 is located between the gear 25 and the support. The above-mentioned gear 225 and gear 26 are coaxially fixedly connected with the shaft, and fixed blocks 27 are arranged on both sides of the support, and a guide groove is penetrated on the fixed block 27, and a rack 28 is arranged in the guide groove.

The movable block on the slide moves linearly on the slide, thereby supporting the push plate 29 while limiting and guiding the movement of the push plate 29.

[0053] The lifting assembly 5 includes a fixed plate 51 and a screw rod 52. The fixed plate 51 is fixedly connected to the working platform 11, and the fixed plate 51 is located at the lower end of the lifting plate 22. The screw rod 52 passes through the middle area of ​​the fixed plate 51, and one end of the screw rod 52 is fixedly connected to the middle area of ​​the lifting plate 22. A nut is sleeved on the screw rod 52, and a gear three is fixedly installed on the outer side of the nut. The gear three is rotatably connected to the fixed plate 51. A motor is arranged on the fixed plate 51, and a gear four is coaxially connected to the motor output shaft. The gear four meshes with the gear three, and the gear three is driven to rotate by the gear four, thereby rotating the nut. Since the screw rod 52 is connected to the lifting plate 22 and is in a fixed state, the screw rod 52 moves linearly along the axis of the nut, and then the lifting of the lifting plate 22 achieved by the screw rod 52 causes the air-conditioning equipment to be pushed to an appropriate installation height.

[0054] During use, the air conditioner is first placed on the bearing plate 23. Then, under the gravity of the air conditioner, the elastic sheet is deformed and the bearing plate 23 is lowered toward the lifting plate 22. Finally, the bearing plate 23 is in contact with the lifting plate 22. During the lowering of the bearing plate 23, the slider 1 slides along the linear track 1. As the slider 1 moves, the half tooth 24 rotates around the hinge with the hinge groove 221.

[0055] During the rotation of the half tooth 24, the half tooth 24 will drive the gear 1 25 to rotate, and the shaft will rotate, thereby causing the gear 2 26 to rotate, and the gear 2 26 will rotate to drive the rack 28 to move along the guide groove, and the two push plates 29 will gradually approach each other. When the push plate 29 moves to the limit position, the transverse moving component 3 will be in close contact with the side wall of the air conditioning equipment;

[0056] Then, the piston end of the hydraulic rod 14 is controlled to extend, and the hydraulic rod 14 is used to change the lifting frame 13 from a retracted state to an expanded state. At this time, the working platform 11 will gradually move away from the ground under the push of the lifting frame 13, so that the installer and the air-conditioning equipment are lifted to a fixed height. Then, the motor is started, and the motor output shaft is used to drive the gear four to rotate, so that the gear four drives the gear three to rotate, and the gear three will drive the nut to rotate. Since the screw rod 52 is fixedly connected to the lifting plate 22, the screw rod 52 will gradually rise along the axis of the nut while the nut rotates. At this time, the lifting plate 22 will gradually rise to a suitable installation position under the lifting action of the screw rod 52. Example 2

At this time, the avoidance block 3231 will push the ejector rod 3241, so that the spring 2 is compressed and deformed, and at the same time, the end of the ejector rod 3241 close to the guide plate 31 will be inserted into the fixed hole 312. At this time, the guide plate 31 will be in a locked state with the traverse plate 32, that is, when the traverse plate 32 is pushed, the traverse plate 32 cannot move;

[0061] When the lifting assembly 5 pushes the lifting plate 22 to lift the air conditioner to the appropriate installation position, the air conditioner will drive the longitudinal plate 33 to move along the slide groove 2. At this time, the fixed groove will be misaligned with the ball 3212, causing the ball 3212 to drive the installation rod to move toward the end away from the longitudinal plate. At this time, the driving block 3213 will push the avoidance block 3231 and force the spring 1 to deform and compress. As the avoidance block 3231 moves toward the end away from the installation rod, the roller will roll into the avoidance groove 3232. At this time, the push rod 3241 will move in the direction of the transverse plate 32 under the elastic force of the spring 2. At this time, the end of the push rod 3241 inserted into the fixed hole 312 will be disengaged. At this time, the locking between the guide plate 31 and the transverse plate 32 will be released, that is, the transverse plate 32 is pushed at this time, and the transverse plate 32 will move linearly along the linear track 1;

[0062] When the limit between the traverse plate 32 and the guide plate 31 is released, the air-conditioning device can be pushed so that the air-conditioning device gradually approaches and fits the wall surface.

[0063] The remaining structures are the same as those of Example 1. Example 3

[0064] Reference Figure 1-12 , which is the third embodiment of the present invention, and this embodiment is different from the second embodiment in that:

[0065] Buffer components 4 are provided on both sides of the working platform 11, and the buffer components 4 include a plug barrel 41 and an air cushion 42. The air cushion 42 is connected to one end of the traverse plate 32. The plug barrel 41 is fixedly installed on the side wall of the working platform 11, a plug plate 43 is arranged in the plug barrel 41, and a pull rod 44 is arranged in the middle area of ​​one side of the plug plate 43. The pull rod 44 passes through one end of the plug barrel 41, and the end of the pull rod 44 away from the plug plate 43 is connected to the push plate 29, a one-way valve, an air guide pipe 1 45, and an air guide pipe 2 46 are arranged at the end of the plug barrel 41 close to the push plate 29, a through groove is opened on the push plate 29, and an air outlet groove 313 is arranged on the guide plate 31, the end of the air guide pipe 1 45 away from the plug barrel 41 passes through the through groove and is connected to the air outlet groove 313 and is internally connected, and the end of the air guide pipe 2 46 away from the plug barrel 41 is connected to the air cushion 42 and is internally connected.

[0066] During use, when the two push plates 29 approach each other and limit the position of the air conditioner, the push plate 29 will drive the plug plate 43 to move in the plug cylinder 41 through the pull rod 44, so that the gas in the plug cylinder 41 is introduced into the air cushion 42 through the second air guide pipe 46 under the pressure of the plug plate 43, and the air cushion 42 will gradually expand due to the filling of gas;

[0067] When the air-conditioning device is pushed toward the wall, the transverse plate 32 will gradually be misaligned with the guide plate 31, so that the air outlet groove 313 originally blocked by the transverse plate 32 is exposed, and when the air-conditioning device is pushed, the air cushion 42 will contact the wall surface before the air-conditioning device. As the transverse plate 32 continues to move, the gas in the air cushion 42 will return to the plug tube 41 through the air guide pipe 45, and then be discharged through the air guide pipe 45 to the air outlet groove 313, so that the air cushion 42 is used to buffer the air-conditioning device when the air-conditioning device approaches the wall, thereby avoiding rigid contact between the air-conditioning device and the wall surface, avoiding wear on the outer shell of the air-conditioning device and damage to the wall.

[0068] The remaining structure is the same as that of Example 2. Example 4

[0069] Reference Figure 1-12 , which is a fourth embodiment of the present invention, provides: a working method of an automatic telescopic ladder device for electrical installation, comprising the following steps,

[0070] S1, first, place the air conditioner with mounting on the bearing plate 23. Under the action of the air conditioner's own gravity, the bearing plate 23 will sink, and then the slider 1 will slide in the wire groove 1. As the slider 1 moves, the half tooth 24 will rotate around the hinge point between it and the hinge groove 221 as the axis.

[0071] S2, when the half tooth 24 rotates, driven by the half tooth 24, the gear 1 25 will rotate, and then the gear 2 26 will move synchronously with the gear 1 25, and the gear 2 26 will drive the rack 28 to move linearly along the guide groove in the fixed block 27, and the two racks 28 will drive the straight rod and the push plate 29 to approach each other, and then push the transverse moving part 3 to contact with both sides of the air-conditioning equipment, and the transverse moving part 3 will limit the two sides of the air-conditioning equipment under the drive of the blocking part 2;

[0072] S3, then the installer stands on the working platform 11 and starts the hydraulic rod 14, at which time the piston end of the hydraulic rod 14 extends, and then the lifting frame 13 will be unfolded under the push of the piston end of the hydraulic rod 14, and at this time the working platform 11 will be lifted to a fixed height;

[0073] S4, at this time, the height of the air-conditioning equipment being lifted and lowered still deviates from the preset installation position, and the motor is started, and then the motor output shaft will drive gear four, so that gear four drives gear three to rotate, and gear three will rotate the nut synchronously during the rotation process. Since the screw rod 52 is fixedly connected to the lifting plate 22, when the nut rotates, the screw rod 52 will move linearly along the central axis of the nut, and then the lifting plate 22, the bearing plate 23, and the air-conditioning equipment arranged on the bearing plate 23 will move upward along the central axis of the nut under the pushing action of the screw rod 52, so that the air-conditioning equipment can be fine-tuned to the preset air-conditioning equipment installation position height;

[0074] S5, when the lifting assembly 5 lifts the air conditioner to the preset installation position, the air conditioner will drive the longitudinal moving plates 33 in the transverse moving parts 3 on both sides to move linearly along the second slide groove during the movement of the air conditioner. At this time, the rolling ball 3212 set in the top ball groove will be pushed to move in the direction of the installation groove 321, and then the installation rod will drive the driving block 3213 to move in the direction of the transverse moving plate 32. During the movement, the driving block 3213 will force the avoidance block 3231 to move linearly along the elastic groove 323 and avoid the driving block 3213. At this time, the spring 1 is compressed and deformed;

[0075] S6, during the movement of the avoidance block 3231, the roller arranged at one end of the top rod 3241 will slide down into the avoidance groove under the push of the spring 2, and at this time, the end of the top rod 3241 away from the roller will be separated from the fixed hole 312 in the guide plate 31, and the traverse plate 32 can slide linearly along the wire groove 1, and the air-conditioning device is gradually pushed to the preset installation position close to the wall by pushing the air-conditioning device;

[0076] S7, when the blocking component 2 drives the traverse component to limit the air-conditioning device, the push plate 29 will drive the pull rod 44 and the plug plate 43 to move synchronously, so that the gas inside the plug cylinder 41 is introduced into the air cushion 42 through the air guide pipe 2 46 under the push of the plug plate 43. At this time, the air cushion 42 will be inflated and expanded. When the air-conditioning device is gradually withdrawn to the wall, the air cushion 42 will contact the wall first, so that the installer can avoid excessive thrust on the air-conditioning device when pushing the air-conditioning device, resulting in rigid contact between the air-conditioning device and the wall, thereby causing wear of the air-conditioning device shell and damage to the wall;

[0077] S8. When the air-conditioning device is pushed, since the air guide pipe 1 45 is connected with the air outlet groove 313, the air cushion 42 is squeezed when it contacts the wall, causing the gas to flow back into the plug tube 41 through the air guide pipe 2 46. Since the plug plate 43 cannot move under the action of the push plate 29 at this time, the gas is guided to the air outlet groove 313 through the air guide pipe 1 45. In the process of the air-conditioning device being pushed, as the transverse plate 32 moves, the air outlet groove 313 will gradually be exposed, causing the gas in the air cushion 42 to be slowly discharged through the air outlet groove 313. At this time, the air cushion 42 will be deflated, causing the air-conditioning device to contact the wall at the preset installation position stably. At this time, the air-conditioning device can be fixedly installed on the wall.

6. A method for operating an automatic telescopic ladder device for electrical installation, using an automatic telescopic ladder device for electrical installation as claimed in claim 5, characterized in that: The molding process includes the following steps: First, the air conditioning device to be installed is placed on the bearing plate (23). Under the action of the air conditioning's own gravity, the bearing plate (23) will sink, and then the slider 1 will slide in the wire groove 1. As the slider 1 moves, the half tooth (24) will rotate around the hinge point between it and the hinge groove (221) as the axis. When the half tooth (24) rotates, driven by the half tooth (24), gear one (25) will rotate, and then gear two (26) will move synchronously with gear one (25). At this time, gear two (26) will drive the rack (28) to move linearly along the guide groove in the fixed block (27). At this time, the two racks (28) will drive the straight rod and the push plate (29) to approach each other, thereby pushing the transverse moving component (3) to contact the two sides of the air-conditioning device. At this time, the transverse moving component (3) will limit the two sides of the air-conditioning device under the drive of the blocking component (2); Then the installer stands on the working platform (11) and starts the hydraulic rod (14), at which time the piston end of the hydraulic rod (14) extends, and then the lifting frame (13) is unfolded under the push of the piston end of the hydraulic rod (14), and the working platform (11) is lifted to a fixed height; At this time, the height at which the air-conditioning device is lifted still deviates from the preset installation position. By starting the motor, the motor output shaft will drive gear four, causing gear four to drive gear three to rotate. During the rotation of gear three, the nut will rotate synchronously. Since the screw rod (52) is fixedly connected to the lifting plate (22), when the nut rotates, the screw rod (52) will move linearly along the center axis of the nut, thereby causing the lifting plate (22), the supporting plate (23), and the air-conditioning device arranged on the supporting plate (23) to move upward along the center axis of the nut for fine adjustment under the pushing action of the screw rod (52), so that the air-conditioning device can be fine-tuned to the preset air-conditioning device installation position height.

7. A method for operating an automatic telescopic ladder device for electrical installation as claimed in claim 6, characterized in that: When the lifting assembly (5) lifts the air-conditioning device to the preset installation position, the air-conditioning device will drive the longitudinal moving plates (33) in the transverse moving parts (3) on both sides thereof to move linearly along the second slide groove during the movement process. At this time, the rolling ball (3212) arranged in the top ball groove will be pushed to move in the direction of the installation groove (321), and then the installation rod will drive the driving block (3213) to move in the direction of the transverse moving plate (32). During the movement process, the driving block (3213) will force the avoidance block (3231) to move linearly along the elastic groove (323) and avoid the driving block (3213). At this time, the spring 1 is compressed and deformed; During the movement of the avoidance block (3231), the roller provided at one end of the push rod (3241) will slide down into the avoidance groove under the push of the second spring, and at this time, the end of the push rod (3241) away from the roller will be separated from the fixed hole (312) in the guide plate (31), and the traverse plate (32) can slide linearly along the first wire groove, so that the air-conditioning device is gradually pushed to a preset installation position close to the wall by pushing the air-conditioning device; When the blocking component (2) drives the transverse moving component to limit the position of the air-conditioning device, the push plate (29) will drive the pull rod (44) and the plug plate (43) to move synchronously, so that the gas inside the plug cylinder (41) is introduced into the air cushion (42) through the second air guide pipe (46) under the push of the plug plate (43). At this time, the air cushion (42) will be inflated and expanded. When the air-conditioning device is gradually withdrawn to be close to the wall, the air cushion (42) will contact the wall first, so that the installer can avoid applying too much thrust to the air-conditioning device when pushing the air-conditioning device, resulting in rigid contact between the air-conditioning device and the wall, thereby causing wear of the air-conditioning device shell and damage to the wall; When the air conditioning device is pushed, since the air guide pipe 1 (45) is connected to the air outlet groove (313), when the air cushion (42) contacts the wall, the air cushion (42) is squeezed, causing the gas to flow back into the plug tube (41) through the air guide pipe 2 (46). Since the plug plate (43) cannot move under the action of the push plate (29) at this time, the gas is guided to the air outlet groove (313) through the air guide pipe 1 (45). In the process of the air conditioning device being pushed, as the traverse plate (32) moves, the air outlet groove (313) will gradually be exposed, causing the gas in the air cushion (42) to be slowly discharged through the air outlet groove (313). At this time, the air cushion (42) will be deflated, causing the air conditioning device to stably contact the wall at the preset installation position. At this time, the air conditioning device can be fixedly installed on the wall.
