Description

Technical Field

[0001] The invention relates to a leveling device, in particular to a leveling device for a base and a vertical air conditioner. Background Art

[0002] In today's society, people's demands for comfort, health, and personalization are constantly increasing, and home decoration and design are no longer as stereotyped as they used to be. Due to personal preferences and environmental factors, the following problems may arise during the installation of large household appliances: 1. The designated location cannot be placed due to uneven ground, or the air conditioner is unstable when placed in the designated location; 2. The air conditioner is placed in the user's desired location, but at a certain angle to the horizontal plane, affecting the appearance; 3. The leveling devices currently used are mostly adjusted from the bottom of the large household appliance base, which requires the large household appliance to be lifted during the adjustment process. Due to the large size and weight of large household appliances, moving them is very difficult, which greatly inconveniences the leveling operation. Taking vertical air conditioners as an example, these instability issues will cause the air conditioner to produce louder noise, reduce the excellent user experience, and even cause damage to the air conditioner, shortening its service life and causing user complaints.

[0003] On the other hand, since the base of a floor-standing air conditioner has a large contact area with the ground and is mostly made of plastic, it can easily scratch the floor when moving the unit. Furthermore, the base of the floor-standing air conditioner forms a closed space with the ground, increasing the chance of mold on the floor.

[0004] Based on this, the present invention proposes a new leveling device and a vertical air conditioner to solve the above problems. Summary of the Invention

[0021] To make the embodiments, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, rather than all of them. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] First refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 : is a schematic diagram of the overall structure of the embodiment 1 of the leveling device for the base of the present invention from different viewing angles. Figure 1 and Figure 2 As shown, the base 1 is used to carry the carried object, and the carried object can be a large household appliance, such as a vertical air conditioner, a refrigerator, a washing machine, etc. The leveling device for the base of the present invention includes at least one leveling mechanism 2 fixed to the lower surface 11 of the base 1. In this embodiment, there are four leveling mechanisms 2, and they are evenly distributed on the lower surface 11 of the base 1. It can be understood by those skilled in the art that the number of leveling mechanisms 2 provided on the lower surface of the base 1 can be flexibly selected according to actual design needs, such as providing one, two, three or even more, and the installation method of the leveling mechanism 2 can also be flexibly designed according to actual needs, without departing from the protection scope of the present invention. In addition, since the upper surface 12 of the base 1 can carry the carried object, the shape of the base 1 can be flexibly designed according to the size of the carried object. For example, in this embodiment, the edge of the base 1 is provided as a flange structure, so that the lower surface is recessed inward to leave space for installing the leveling mechanism 2. Moreover, those skilled in the art can also provide the base 1 and the carried object as an integral structure or a split structure according to actual needs, without departing from the protection scope of the present invention. The use of the leveling mechanism of the present invention can make the user's leveling operation simpler and more convenient. The following is combined with Figure 3 The structure of the leveling mechanism of the first embodiment is described in detail.

[0023] Reference Figure 3 , Figure 3 Schematic diagram of the structure of the embodiment 1 of the leveling mechanism of the present invention. Figure 3 As shown, the leveling mechanism 2 includes an adjusting seat 21, an adjusting rod 22 and a leveling rod 23. An adjusting through hole 210 is provided inside the adjusting seat 21. The adjusting rod 22 is provided in the adjusting through hole 210. The leveling rod 23 forms a linkage mechanism with the adjusting rod 22 through a connecting portion 24. The connecting portion 24 is configured so that when the adjusting rod 22 moves left and right along the adjusting through hole 210 under the action of external force, the connecting portion 24 drives the leveling rod 23 to move up and down to level the base 1.

[0024] In this embodiment, the outer surface of the adjustment rod 22 is provided with an external thread, and the inner surface of the adjustment hole 210 is provided with an internal thread matching the external thread on the outer surface of the adjustment rod 22. Under the action of external force, the adjustment rod 22 can move axially along the adjustment hole 23 in a rotating manner. Specifically, the other end of the adjustment seat 21 ( Figure 3An adjustment hole end cover 212 is provided at the left end of the middle adjustment seat 21. The adjustment hole end cover 212 is used to close or open the adjustment hole 210. When the adjustment hole end cover 212 is open, the user can use a suitable tool such as a screwdriver to reach into the adjustment hole 210 from the opening at the left end of the adjustment seat 21, and then rotate the adjustment rod 22 clockwise or counterclockwise. The external thread of the adjustment rod 22 interacts with the internal thread of the adjustment hole 210 to make the adjustment rod 22 move left and right in the adjustment hole 210.

[0025] Preferably, return to reference Figure 1 and Figure 2 ,like Figure 1 and Figure 2 As shown, the outer edge of the base 1 is provided with through holes 13 matching the number of the leveling mechanism 2. When the leveling mechanism 2 is fixed to the base 1, the through holes 13 are connected with the adjustment through holes 210. That is, the adjustment through holes 210 and the through holes 13 can be regarded as a whole "adjustment through hole", and the through hole 13 can be regarded as the adjustment through hole 210 at the left end ( Figure 3 At this time, the adjusting through-hole end cover 211 can be covered on the through-hole 13, that is, the adjusting through-hole 210 can be closed or opened by closing or opening the through-hole 13. Those skilled in the art will understand that the adjusting through-hole end cover 211 can not only prevent foreign matter from entering the adjusting through-hole 210, but also maintain the overall aesthetics of the base 1 after the adjusting through-hole end cover 211 is covered on the through-hole 13 on the outer edge of the base 1. In addition, when the base 1 is used to carry a carried object, since a through-hole is provided on the outer edge of the base 1, when the user needs to level the base 1, he only needs to open the adjusting through-hole end cover 211 to adjust the height of the base to achieve the purpose of leveling the base 1, and there is no need to lift the entire base 1 for adjustment (usually the carried object on the base 1 is usually heavy, and it is inconvenient to lift it up), thereby bringing great convenience to the user.

[0026] Continue to refer to Figure 3 The connecting portion 24 includes a movable slider 240 and a first connecting rod 241 and a second connecting rod 242 that are hinged to each other. The movable slider 240 is fixedly connected to the adjusting rod 22 in the axial direction in a manner that allows the adjusting rod 22 to rotate. The first end of the first connecting rod 241 ( Figure 3 The left end of the first connecting rod in the middle is hinged to the movable slider 240, and the second end of the first connecting rod 241 ( Figure 3 The right side end of the first connecting rod) and the first end of the second connecting rod 242 ( Figure 3 The left end of the second connecting rod in the middle is hinged, and the second end of the second connecting rod 242 ( Figure 3 The right side end of the second connecting rod in the middle is hinged to the adjustment seat 21, and the first end of the leveling rod 23 ( Figure 2The right end of the middle leveling rod is hinged to the moving slider 240, and the first end of the leveling rod 23 is connected to the first end of the first connecting rod 241 at the moving slider 240 through gear meshing.

[0027] Since the movable slider 240 is axially fixedly connected to the adjusting rod 22 in a manner that allows the adjusting rod 22 to rotate, when the adjusting rod 22 rotates counterclockwise or clockwise under the action of an external force, the adjusting rod 22 moves left and right along the adjusting through hole 210, and drives the movable slider 240 to move left and right in the horizontal direction. The movable slider 240 further drives the leveling rod 23 and the first connecting rod 241 to move, so that the angle between the leveling rod 23 and the first connecting rod 241 changes. In this way, the first end of the leveling rod 23 ( Figure 3 The left end of the middle leveling rod) and the second end of the leveling rod 23 will change in the vertical direction, thereby changing the relative position between the base 1 and the ground, thereby achieving the purpose of leveling the base 1. It will be understood by those skilled in the art that since the second end of the second connecting rod 242 is hinged to the adjustment base 21, and the first end of the second connecting rod 242 is hinged to the second end of the first connecting rod 241, the angle between the leveling rod 23 and the first connecting rod 241 can be limited, thereby ensuring that the leveling rod 23 can be fixed in the adjusted position after being adjusted to a certain appropriate position (the position when the base 1 is horizontal), so that the base 1 is stably in a horizontal position.

[0028] In the above embodiment, in addition to the movable slider 240 being fixedly connected axially to the adjusting rod 22 in a manner allowing the adjusting rod 22 to rotate, those skilled in the art can also adopt any other suitable connection method to form a worm gear structure between the adjusting rod 22 and the movable slider 240, etc., as long as the purpose of driving the movable slider 240 to move left and right during the rotation of the adjusting rod 22 can be achieved.

[0029] Continue to refer to Figure 3 , one end of the adjustment seat 21 ( Figure 3 A fixing portion 211 is provided at the right end of the middle adjustment seat, and the fixing portion 211 is used to fix the second end of the second connecting rod 242, that is, the second end of the second connecting rod 242 is hinged to the fixing portion 211.

[0030] As another embodiment of the present invention, refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 : is a schematic diagram of the overall structure of the second embodiment of the leveling device for the base of the present invention from different viewing angles. Figure 4 and Figure 5As shown, the difference between Example 2 and Example 1 lies in the different methods for driving the adjustment rod 22. Specifically, in Example 1, through-holes 13 are provided on the outer edge of the base 1, through which the adjustment rod 22 is rotated; in Example 2, holes are provided on the inner surface 12 of the base 1, equal to the number of holes in the adjustment mechanism 2. The fixed portion 211 is provided with a driving rod 2110. The driving rod 2110 penetrates the fixed portion 211 through the holes on the inner surface 12 of the base 1 and forms a linkage mechanism with the adjustment rod 22. The driving rod 2110 can drive the adjustment rod 22 to move left and right along the adjustment through-hole 210 under the action of an external force. In other words, in Example 2, the user lifts the object being carried on the base 1, exposing the driving rod 2110, and then adjusts the height of the base 1 to achieve the purpose of leveling the base.

[0031] In the second embodiment, the linkage mechanism between the drive rod 2110 and the adjustment rod 22 can be a worm gear linkage mechanism. This structure can be designed to be adaptable to the shape of the fixing portion 211 and will not be described in detail here. In addition, the linkage mechanism between the drive rod 2110 and the adjustment rod 22 can also be: a drive gear (not shown) is provided on the drive rod 2110, and the adjustment rod 22 is provided with saw teeth (not shown) that can mesh with the drive gear. The drive gear and the saw teeth form a linkage mechanism. When the drive rod 2110 is rotated clockwise or counterclockwise, the drive rod 2110 drives the adjustment rod 22 to move left and right along the adjustment through hole 210.

[0032] In summary, the leveling device of the present invention achieves the purpose of leveling the base through a leveling mechanism installed on the lower surface of the base, making the leveling operation simpler and more convenient for the user. Since the installation location of the supported object may have an uneven ground, it is necessary to level the supported object. Especially when a heavy supported object is placed on the base, the leveling device of the present invention can apply an external force to the adjustment rod through the through hole on the outer edge of the base without lifting the supported object. The adjustment rod then drives the leveling rod up and down through the connecting portion to adjust the height of the base, thereby achieving the purpose of leveling the base. The present invention is particularly suitable for the installation of some large household appliances. On the one hand, large household appliances are heavy and inconvenient to lift. On the other hand, some large household appliances, such as vertical air conditioners, can generate noise and vibration if improperly installed (for example, if the installation location is uneven). The present invention can further enhance the stability of large household appliances, thereby reducing the noise and vibration caused by the instability of large household appliances. In addition, the leveling device of the present invention is applicable to bases of various specifications, so there is no need to make major changes to existing equipment. It only needs to design a suitable base according to the structure of the supported object to support the supported object.

[0033] The present invention also provides a vertical air conditioner, which includes an air conditioner body and the above-mentioned leveling device. The body of the vertical air conditioner is arranged on the base. It can be an integral structure with the base or a separate structure, all of which do not deviate from the scope of protection of the present invention. It can be understood by those skilled in the art that when the vertical air conditioner adopts the leveling device of the present invention, the air conditioner body is the carried object. If the vertical air conditioner has a base, there is no need to make major changes to the base of the vertical air conditioner. An appropriate number of leveling mechanisms can be directly installed on the base of the vertical air conditioner. Moreover, the method of adjusting through the through holes on the outer edge of the base does not require lifting the air conditioner, making it easy for the user to level it, thereby ensuring that the air conditioner can be stably installed in any position, reducing the noise and vibration caused by the instability of the air conditioner, and minimizing the risk of the air conditioner tipping over.

[0034] Thus far, the technical solutions of the present invention have been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
