DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides an embodiment: a DC variable frequency wall-mounted machine, comprising: a mounting sleeve 1 and a DC variable frequency wall-mounted machine body 2, a threaded rod 3 is rotatably mounted in the middle of the mounting sleeve 1 in the vertical direction, the surface of the threaded rod 3 and the inside of the mounting sleeve 1 are rotatably mounted through a bearing to improve the rotation stability of the threaded rod 3, the mounting sleeve 1 is fixedly mounted on the wall surface, and the upper end of the threaded rod 3 extends to the outside of the mounting sleeve 1, the bottom of the threaded rod 3 is flush with the bottom of the mounting sleeve 1, a servo motor 4 is fixedly mounted on the top of the mounting sleeve 1, and the output end of the servo motor 4 is fixedly connected to the top of the threaded rod 3, and a first telescopic sleeve 5 is slidably mounted on the inner wall of the mounting sleeve 1 , and the inner wall of the upper end of the first telescopic sleeve 5 is fixedly connected with an internal threaded sleeve 501, the inner ring of the internal threaded sleeve 501 is threadedly installed with the surface of the threaded rod 3, the surface of the threaded rod 3 is movably installed with a second telescopic sleeve 6, and the inner wall of the upper end of the second telescopic sleeve 6 is rotatably installed on the outer wall of the internal threaded sleeve 501, the surface of the second telescopic sleeve 6 is threadedly installed with a third telescopic sleeve 7, and the outer wall of the third telescopic sleeve 7 is slidably installed on the inner wall of the first telescopic sleeve 5, the bottom of the third telescopic sleeve 7 is fixedly installed with a mounting plate 8, and the bottom of the mounting plate 8 is fixedly installed on the top of the DC variable frequency wall-mounted machine body 2, and a drainage telescopic hose 202 is provided on one side of the DC variable frequency wall-mounted machine body 2. When it is necessary to remove the filter plate inside the DC variable frequency wall-mounted air conditioner for cleaning, the servo motor 4 is started to make the output end of the servo motor 4 drive the threaded rod 3 to rotate. At this time, the surface of the threaded rod 3 engages with the surface of the internal threaded sleeve 501 through rotation. Since the outer wall of the first telescopic sleeve 5 is slidably installed with the inner wall of the installation sleeve 1, at this time, under the engagement of the internal threaded sleeve 501 with the surface of the threaded rod 3, the lower end of the first telescopic sleeve 5 moves toward the outside of the installation sleeve 1 in the vertical direction, and during the movement of the first telescopic sleeve 5, the internal threaded sleeve 501 drives the second telescopic sleeve 6 to move downward. At the same time, since the inner wall of the second telescopic sleeve 6 is slidably installed in the guide groove 301 on the surface of the threaded rod 3 through the guide block 601, during the rotation of the threaded rod 3, the second telescopic sleeve 6 moves toward the installation sleeve 1 as the threaded rod 3 rotates. The third telescopic sleeve 7 is also moved to the outside of the mounting sleeve 1 because the outer wall of the third telescopic sleeve 7 is slidably mounted on the inner wall of the first telescopic sleeve 5. At this time, the third telescopic sleeve 7 also moves to the outside of the mounting sleeve 1. In this way, multi-stage telescopic expansion and contraction is achieved, so that the mounting plate 8 at the bottom of the third telescopic sleeve 7 drives the DC variable frequency wall-mounted machine body 2 to move to the bottom of the next wall. After the first telescopic sleeve 5 and the third telescopic sleeve 7 are completely lowered into place, the servo motor 4 stops rotating. At this time, the user can take out the filter plate inside the DC variable frequency wall-mounted machine body 2 for cleaning without climbing, which further provides convenience for cleaning and replacement of the internal filter plate of the DC variable frequency wall-mounted air conditioner, improves safety, and has a compact structure and occupies a small area.

[0019] See also Figure 1 and Figure 3In this embodiment, four guide grooves 301 are formed on the surface of the threaded rod 3 at equal intervals along the circumference, and four guide blocks 601 are fixedly connected to the inner wall of the second telescopic sleeve 6 at equal intervals along the circumference, and the four guide blocks 601 are all slidably installed inside adjacent guide grooves 301. The inner wall of the second telescopic sleeve 6 is slidably installed inside the guide grooves 301 on the surface of the threaded rod 3 through the guide blocks 601, further improving the stability of the movement of the second telescopic sleeve 6.

[0020] See also Figure 1-2 In this embodiment, a bearing is arranged on the surface of the internal thread sleeve 501, and the inner ring of the bearing is fixedly connected to the surface of the internal thread sleeve 501, and the outer ring of the bearing is fixedly connected to the inner wall of the upper end of the second telescopic sleeve 6. The bearing arrangement improves the rotation stability of the second telescopic sleeve 6.

[0021] See also Figure 1 In this embodiment, the top of the DC inverter wall-mounted machine body 2 is symmetrically fixedly connected with a connection block 201, and the inside of the mounting plate 8 is symmetrically threaded with a fastening bolt 9, and the lower end of the fastening bolt 9 is rotatably mounted inside the adjacent connection block 201. The top of the DC inverter wall-mounted machine body 2 and the mounting plate 8 are threadedly mounted, which provides convenience for disassembly and assembly between the two.

[0022] See also Figure 1 In this embodiment, an elastic rubber block is symmetrically fixedly mounted on the top wall of the installation sleeve 1, and the bottom of the elastic rubber block is placed on the top surface of the first telescopic sleeve 5. Through the arrangement of the elastic rubber block, the output end of the servo motor 4 drives the threaded rod 3 to rotate in the opposite direction, so that the first telescopic sleeve 5 is retracted and moved toward the inside of the installation sleeve 1. When the first telescopic sleeve 5 is retracted to the inside of the installation sleeve 1, the top of the first telescopic sleeve 5 is pressed against the surface of the elastic rubber pad to limit the movement of the first telescopic sleeve 5.

[0023] Working principle: Turn on the power supply. When it is necessary to remove the filter plate inside the DC variable frequency wall-mounted air conditioner for cleaning, start the servo motor 4 so that the output end of the servo motor 4 drives the threaded rod 3 to rotate. At this time, the surface of the threaded rod 3 engages with the surface of the internal threaded sleeve 501 through rotation. Since the outer wall of the first telescopic sleeve 5 is slidably installed with the inner wall of the installation sleeve 1, at this time, under the engagement of the internal threaded sleeve 501 with the surface of the threaded rod 3, the lower end of the first telescopic sleeve 5 moves vertically toward the outside of the installation sleeve 1, and during the movement of the first telescopic sleeve 5, the internal threaded sleeve 501 drives the second telescopic sleeve 6 to move downward. At the same time, since the inner wall of the second telescopic sleeve 6 is slidably installed in the guide groove 301 on the surface of the threaded rod 3 through the guide block 601 Inside, during the rotation of the threaded rod 3, the second telescopic sleeve 6 rotates and moves toward the bottom of the installation sleeve 1 as the threaded rod 3 rotates, so that the second telescopic sleeve 6 drives the third telescopic sleeve 7 installed on the outer wall thread to engage, and because the outer wall of the third telescopic sleeve 7 is slidably installed on the inner wall of the first telescopic sleeve 5, the third telescopic sleeve 7 also moves toward the outside of the installation sleeve 1. In this way, multi-stage telescopic expansion is achieved, so that the mounting plate 8 at the bottom of the third telescopic sleeve 7 drives the DC variable frequency wall-mounted machine body 2 to move to the bottom of the next wall. After the first telescopic sleeve 5 and the third telescopic sleeve 7 are completely lowered into place, the servo motor 4 stops rotating, and the user can take out the filter plate inside the DC variable frequency wall-mounted machine body 2 for cleaning.
