Description

Technical Field

[0001] This invention relates to the technical field of air conditioners, and more specifically, to a lifting mechanism, a base, and an air conditioner. Background Technology

[0002] As air conditioners become increasingly common, people's demands for them are also rising. In existing technology, the upper part of the air conditioner's base is fixedly fitted with the front panel and rear panel, resulting in a fixed overall height of the air conditioner. This means that the height of the air outlet cannot be adjusted, which limits the application scenarios of the air conditioner. Summary of the Invention

[0003] The first objective of this invention is to provide a lifting mechanism to solve the technical problem in the prior art where the overall height of the air conditioner is fixed, resulting in the inability to adjust the height of the air outlet.

[0004] The lifting mechanism provided by the present invention includes a support base, a threaded rod, and a knob. The support base is rotatably connected to the bottom end of the threaded rod, and the knob is fixedly connected to the top end of the threaded rod. The threaded rod can be installed on a base, and when the knob is rotated, the threaded rod can drive the base to rise or fall.

[0005] The lifting mechanism provided by this invention can produce the following beneficial effects:

[0006] The lifting mechanism provided by this invention can be installed on a base, with the support seat located below the base and the knob located above the base. Taking the base as the base of an air conditioner as an example, when the knob is turned, it drives the threaded rod to rotate, which in turn raises or lowers the base of the air conditioner. This makes the overall height of the air conditioner and the height of the air outlet adjustable, thereby increasing the application scenarios and expanding the application range of the air conditioner.

[0007] Furthermore, the lifting mechanism also includes a mounting plate with a threaded hole, the threaded rod being matched and connected to the threaded hole, and the threaded rod being mounted on the base through the mounting plate.

[0008] Under this technical solution, if the threads inside the threaded hole are damaged, maintenance can be performed by replacing the mounting plate. Moreover, when the base is provided with a through hole for the threaded rod to pass through, the through hole can be a smooth hole, making the processing simple and efficient.

[0009] Furthermore, the lifting mechanism also includes an upper limit sleeve, which is sleeved on the threaded rod and located between the mounting plate and the knob, for limiting the rising height of the base.

[0010] Under this technical solution, when using the lifting mechanism, the mounting plate is positioned below the base and the upper limit sleeve is positioned above the base, that is, the base is positioned between the mounting plate and the upper limit sleeve. When the knob is rotated to raise the base, the distance between the base and the knob becomes smaller and smaller. When the upper end of the upper limit sleeve abuts against the knob and the lower end abuts against the base, the base reaches its highest position.

[0011] Furthermore, the lifting mechanism also includes a protective sleeve, which is sleeved outside the threaded rod, with its top end fixedly connected to the knob and its bottom end movably sleeved inside the upper limit sleeve.

[0012] Under this technical solution, the protective sleeve covers the threaded rod, which not only protects the threaded rod but also improves its aesthetics.

[0013] Furthermore, the lifting mechanism also includes a bearing, which is disposed between the support base and the threaded rod. The outer ring of the bearing is fixedly connected to the support base, and the inner ring of the bearing is fixedly connected to the bottom end of the threaded rod.

[0014] In this technical solution, the bottom end of the threaded rod is rotatably mounted on the support seat via a bearing. The threaded rod and the support seat have rolling friction, which is relatively small, greatly reducing the difficulty of adjustment and ensuring the smooth rotation of the threaded rod. Moreover, the support seat remains stationary when the threaded rod rotates, making it easy to maintain the position of the base.

[0015] Furthermore, the lifting mechanism also includes a lower limit member, which is disposed between the support base and the mounting plate. When the lower surface of the base abuts against the lower limit member, the base descends to its lowest position.

[0016] Under this technical solution, the lower limit component can restrict the lowest position of the substrate.

[0017] Furthermore, the lower limiting component includes a bushing and a limiting block disposed on the outer circumferential surface of the bushing. The inner side of the bushing is fixedly connected to the bottom end of the threaded rod, and the outer side of the bushing is fixedly connected to the inner ring of the bearing. When the lower surface of the base abuts against the limiting block, the base descends to the lowest position.

[0018] In this technical solution, the bushing connects the threaded rod and the bearing, serving as a connection; the limiting block is positioned at a height relative to the support base, thus limiting the lowest position of the base.

[0019] Furthermore, the outer surface of the knob is provided with a scale along its circumference, the scale being used to indicate the rotation angle of the knob and the threaded rod.

[0020] Under this technical solution, the rotation angle of the threaded rod can be intuitively obtained by observing the scale on the knob, thereby understanding the height adjustment of the base and making the adjustment more precise.

[0021] The second objective of this invention is to provide a base that solves the technical problem in the prior art where the overall height of the air conditioner is fixed, resulting in the inability to adjust the height of the air outlet.

[0022] The base provided by the present invention includes a body and the above-mentioned lifting mechanism. The threaded rod is installed on the body, and when the knob is rotated, the threaded rod can drive the body to rise or fall.

[0023] The base provided by this invention allows for adjustment of the overall height of the air conditioner and the height of the air outlet when the knob is turned. This increases the application scenarios and expands the application range of the air conditioner.

[0024] Furthermore, the lifting mechanism also includes a mounting plate with a threaded hole, and the threaded rod is matched and connected to the threaded hole; the body has a through hole, the threaded rod passes through the through hole, the mounting plate is fixedly installed on the body, and the body is supported by the support base.

[0025] Under this technical solution, the through hole can be a smooth hole or a threaded hole. When the through hole is a smooth hole, the processing is simple and efficient; when the through hole is a threaded hole, the connection area between the threaded rod and the base increases, which can increase the support force of the threaded rod on the base.

[0026] Furthermore, the outer edge of the main body is provided with a plurality of receiving cylinders, and a fixing plate is provided inside the receiving cylinders. The mounting plate is fixedly installed on the bottom of the fixing plate. When the main body is in the lowest position, the bottom end of the receiving cylinder abuts against the support base.

[0027] Under this technical solution, the accommodating cylinder houses the threaded rod and mounting plate, etc., and provides shielding and protection for them.

[0028] Furthermore, the lifting mechanism also includes an upper limit sleeve, which is sleeved outside the threaded rod, located between the fixed plate and the knob, and movably sleeved inside the receiving cylinder. When the body is in the lowest position, the top end of the receiving cylinder is connected to the bottom end of the upper limit sleeve.

[0029] Under this technical solution, the upper limit sleeve can provide shielding and protection for the threaded rod throughout the entire height adjustment range.

[0030] The third objective of this invention is to provide an air conditioner that solves the technical problem in the prior art where the overall height of the air conditioner is fixed, resulting in the inability to adjust the height of the air outlet.

[0031] The air conditioner provided by the present invention includes the aforementioned base, as well as a front panel and a rear panel, both of which are fixedly mounted on the base.

[0032] The air conditioner provided by this invention has a lifting mechanism in the base that can drive the main body to rise and fall, thereby making the overall height of the air conditioner and the height of the air outlet adjustable, which can increase the application scenarios and expand the application range.

[0042] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

[0043] This embodiment provides a lifting mechanism 100, such as Figure 3 and Figure 4 As shown, the lifting mechanism 100 includes a support base 110, a threaded rod 130, and a knob 170. The support base 110 is rotatably connected to the bottom end of the threaded rod 130, and the knob 170 is fixedly connected to the top end of the threaded rod 130. The threaded rod 130 can be installed on the base, and when the knob 170 is rotated, the threaded rod 130 can drive the base to rise or fall.

[0044] In this embodiment, the base is the body 200 of the air conditioner's base 010. During use, the lifting mechanism 100 is installed on the body 200, with the support base 110 positioned below the body 200 and the knob 170 positioned above it. When the knob 170 is turned, it drives the threaded rod 130 to rotate, causing the body 200 to rise or fall. This allows the overall height of the air conditioner and the height of the air outlet to be adjusted, thereby increasing the application scenarios and expanding the application range of the air conditioner.

[0045] It should be noted that in this embodiment, the base is the body 200 of the air conditioner base 010. However, in other embodiments of this application, the base can also be other products that require height adjustment.

[0046] Specifically, in this embodiment, as Figure 3 and Figure 4 As shown, the lifting mechanism 100 also includes a mounting plate 140, which has a threaded hole. A threaded rod 130 is matched and connected to the threaded hole, and the threaded rod 130 is mounted on the base through the mounting plate 140. In this configuration, if the threads in the threaded hole are damaged, maintenance can be performed by replacing the mounting plate 140. Moreover, when the base has a through hole for the threaded rod 130 to pass through, the through hole can be a smooth hole, making processing simple and efficient.

[0047] More specifically, in this embodiment, the lifting mechanism 100 is fixedly installed on the body 200 of the air conditioner base 010 by screws.

[0048] Specifically, in this embodiment, as Figure 3 and Figure 4As shown, the lifting mechanism 100 also includes an upper limit sleeve 150, which is sleeved outside the threaded rod 130 and located between the mounting plate 140 and the knob 170, used to limit the rising height of the base. When using the lifting mechanism 100, the mounting plate 140 is positioned below the base and the upper limit sleeve 150 is positioned above the base, that is, the base is positioned between the mounting plate 140 and the upper limit sleeve 150; when the knob 170 is rotated to raise the base, the distance between the base and the knob 170 becomes smaller and smaller. When the upper end of the upper limit sleeve 150 abuts against the knob 170 and the lower end abuts against the base, the base reaches its highest position.

[0049] Specifically, in this embodiment, the following continues... Figure 3 and Figure 4 As shown, the lifting mechanism 100 also includes a protective sleeve 160, which is sleeved around the threaded rod 130, with its top end fixedly connected to the knob 170 and its bottom end movably sleeved inside the upper limit sleeve 150. In this configuration, the protective sleeve 160 covers the threaded rod 130, providing protection for the threaded rod 130 and also improving its aesthetics.

[0050] It should be noted that the structure of the telescopic sleeve in the prior art, such as the telescopic umbrella handle structure, can be used between the protective sleeve 160 and the upper limit sleeve 150, which will not be elaborated here.

[0051] Specifically, in this embodiment, the lifting mechanism 100 further includes a bearing, which is disposed between the support base 110 and the threaded rod 130. The outer ring of the bearing is fixedly connected to the support base 110, and the inner ring of the bearing is fixedly connected to the bottom end of the threaded rod 130. In this configuration, the bottom end of the threaded rod 130 is rotatably mounted on the support base 110 via the bearing. The friction between the threaded rod 130 and the support base 110 is rolling friction, which is relatively small, greatly reducing the difficulty of adjustment and ensuring the smooth rotation of the threaded rod 130. Moreover, the support base 110 remains stationary when the threaded rod 130 rotates, making it easier to maintain the position of the base.

[0052] Specifically, in this embodiment, the lifting mechanism 100 further includes a lower limit member, which is disposed between the support base 110 and the mounting plate 140. When the lower surface of the base abuts against the lower limit member, the base descends to its lowest position. In other words, the lower limit member can limit the lowest position of the base.

[0053] Specifically, in this embodiment, as Figure 3As shown, the lower limiting component includes a bushing 120 and a limiting block 121 disposed on the outer circumferential surface of the bushing 120. The inner side of the bushing 120 is fixedly connected to the bottom end of the threaded rod 130, and the outer side of the bushing 120 is fixedly connected to the inner ring of the bearing. When the lower surface of the base abuts against the limiting block 121, the base descends to its lowest position. In this technical solution, the bushing 120 connects the threaded rod 130 and the bearing, serving a connecting function; the limiting block 121, with its height relative to the support base 110, is used to limit the lowest position of the base.

[0054] It should be noted that in other embodiments of this application, the lower limit member is not limited to the above-described structural form. For example, the lower limit member can also be a sleeve structure, that is, the lower limit member is a lower limit sleeve, which is sleeved outside the threaded rod 130 and located between the support base 110 and the mounting plate 140, and can abut against the lower surface of the base; or, the lower limit member only includes a limiting block, which is fixedly disposed on the top of the support base 110 and can abut against the base.

[0055] Specifically, in this embodiment, as Figure 3 and Figure 4 As shown, two limiting blocks 121 are symmetrically arranged on both sides of the bushing 120. This arrangement provides more balanced support to the substrate when the limiting blocks 121 abut against it. Of course, in other embodiments of this application, the number of limiting blocks 121 is not limited to two. For example, three limiting blocks 121 are evenly distributed along the circumference of the bushing 120, and all three can abut against the substrate.

[0056] Specifically, in this embodiment, the following continues... Figure 3 and Figure 4 As shown, the outer surface of the knob 170 is provided with a scale 171 along its circumference. The scale 171 is used to indicate the rotation angle of the knob 170 and the threaded rod 130. With this arrangement, by looking at the scale 171 on the knob 170, the rotation angle of the threaded rod 130 can be obtained intuitively, thereby understanding the height adjustment of the base and making the adjustment more precise.

[0057] Specifically, in this embodiment, the following continues... Figure 3 and Figure 4 As shown, an anti-slip pad 111 is provided at the bottom of the support base 110. The anti-slip pad 111 serves to prevent slippage, which helps to keep the support base 110 and the structure above it in a stable position.

[0058] This embodiment also provides a base 010, such as Figure 2As shown, the base 010 includes a main body 200 and the aforementioned lifting mechanism 100. A threaded rod 130 is installed on the main body 200, and when the knob 170 is rotated, the threaded rod 130 can drive the main body 200 to rise or fall. In use, when the knob 170 is rotated, the knob 170 drives the threaded rod 130 to rotate, and the threaded rod 130 drives the main body 200 to rise or fall, making the overall height of the air conditioner adjustable and the height of the air outlet adjustable, thereby increasing the application scenarios and expanding the application range of the air conditioner.

[0059] Specifically, in this embodiment, the lifting mechanism 100 further includes a mounting plate 140, which has a threaded hole, and the threaded rod 130 is matched and connected to the threaded hole; the body 200 has a through hole, through which the threaded rod 130 passes. The mounting plate 140 is fixedly installed on the body 200, and the body 200 is supported by the support base 110. In this configuration, the through hole can be a smooth hole or a threaded hole. When the through hole is a smooth hole, the processing is simple and efficient; when the through hole is a threaded hole, the connection area between the threaded rod 130 and the base increases, which can increase the supporting force of the threaded rod 130 on the base.

[0060] Specifically, in this embodiment, as Figure 2 As shown, the outer edge of the main body 200 is provided with multiple receiving cylinders 210, and a fixing plate is provided inside the receiving cylinder 210. The mounting plate 140 is fixedly installed on the bottom of the fixing plate. When the main body 200 is in the lowest position, the bottom end of the receiving cylinder 210 abuts against the support base 110. The receiving cylinder 210 accommodates the threaded rod 130 and the mounting plate 140, etc., and plays a role in shielding and protecting them.

[0061] More specifically, in this embodiment, continuing as follows Figure 2 As shown, there are four accommodating cylinders 210, which are evenly distributed along the circumference of the body 200. However, it should be noted that in other embodiments of this application, the number of accommodating cylinders 210 is not limited to this, for example, five accommodating cylinders 210 are evenly distributed along the circumference of the body 200.

[0062] Specifically, in this embodiment, the lifting mechanism 100 further includes an upper limit sleeve 150. The upper limit sleeve 150 is sleeved outside the threaded rod 130, located between the fixed plate and the knob 170, and movably sleeved within the receiving cylinder 210. When the main body 200 is in the lowest position, the top end of the receiving cylinder 210 is connected to the bottom end of the upper limit sleeve 150. With this arrangement, the upper limit sleeve 150 can provide protection for the threaded rod 130 throughout the entire height adjustment range.

[0063] This embodiment also provides an air conditioner, such as Figure 1As shown, the air conditioner includes the aforementioned base 010, as well as a front panel 020 and a rear panel 030, both of which are fixedly mounted on the base 010. Because the lifting mechanism 100 in the base 010 can lift the main body 200, the overall height of the air conditioner and the height of the air outlet are adjustable, thus making it suitable for a wide range of applications.

[0064] Finally, it should be noted that in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0065] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to the embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
