Description

Technical Field

[0001] This utility model relates to the field of air conditioning installation technology, specifically to a ceiling-mounted air conditioning unit that is easy to maintain. Background Technology

[0002] Air conditioning units can be classified into horizontal, vertical, and suspended types according to their installation method. Suspended air conditioning units are installed on structures such as ceilings and elevated beams, and are directly fixed with bolts. This type of installation requires climbing to disassemble the unit if it needs to be inspected or replaced after installation, which is very inconvenient and makes subsequent air conditioning maintenance work difficult. Utility Model Content

[0003] To address the technical problems existing in the background art, this utility model provides a ceiling-mounted air conditioning unit that is easy to maintain.

[0004] The technical solution of this utility model is as follows:

[0005] An easy-to-maintain ceiling-mounted air conditioning unit includes an air conditioning unit and a mounting bracket;

[0006] The hoisting frame includes a ring-shaped horizontal frame and a vertical frame for suspending and fixing the horizontal frame;

[0007] The top of the horizontal frame is rotatably connected to at least one pair of support plates. The two support plates in each pair are symmetrically arranged relative to the vertical central axis of the horizontal frame. A snap-fit ​​strip is provided on the upper edge of the side of the air conditioner body corresponding to the position of the support plate, and the support plate can be snapped under the snap-fit ​​strip.

[0008] The rotating part of the support plate is provided with two positioning grooves, which are arranged circumferentially around the axis of rotation of the support plate. A locking member is slidably connected on the horizontal frame. One end of the locking member is engaged with the two positioning grooves in sequence, and the other end extends into the inner hole of the horizontal frame. An elastic member is connected between the locking member and the horizontal frame. A pushing member is provided on the side of the air conditioner body corresponding to the position of the locking member. The pushing member is located below the locking strip and its horizontal protrusion length is greater than that of the locking strip.

[0009] The engagement relationship between the locking strip, the pushing member, the support plate, and the locking member is set such that when the locking member engages with the two positioning slots, the support plate is tilted towards the vertical center axis of the horizontal frame. When the upper edge of the support plate is engaged below the locking strip, the engaging end of the locking member is located between the two positioning slots, and the pushing member is located above the horizontal frame. The upward movement of the pushing frame can push the support plate upward, causing the locking member to engage with one positioning slot, thus releasing the downward movement restriction of the air conditioner body. The downward movement of the pushing frame can push the non-engaging end of the locking member, thus releasing the engagement between the locking member and the positioning slot.

[0010] The support plate has a thickness that is smaller at the top and larger at the bottom to improve its structural strength and support capacity.

[0011] To reduce the overall weight of the hoisting equipment, several weight-reducing grooves are provided on the side of the support plate away from the vertical center axis of the horizontal frame.

[0012] In order not to compromise the supporting capacity of the support plate, several weight-reducing grooves extend vertically and are arranged horizontally.

[0013] In order to provide more stable support for the air conditioner body, the vertical tilt angle of the support plate is 20-30 degrees when the upper edge of the support plate is engaged under the snap strip.

[0014] In one embodiment, the horizontal frame is a rectangular ring frame formed by L-shaped profiles, and the support plate is rotatably connected to the inner corner of the L-shaped profile.

[0015] Preferably, the lower edge of the support plate is cylindrical and tangent to both sides of the L-shaped profile, reducing the stress load on the support plate's pivot axis.

[0016] In one embodiment, a centering frame is provided below the horizontal frame, and a centering hole is provided on the bottom surface of the centering frame for the air conditioner body to pass through, thereby playing a centering and guiding role for the air conditioner body.

[0017] Preferably, the bottom surface of the centering frame is inclined upward toward the center of the centering hole, so that the air conditioner body can be guided toward the center when it moves upward.

[0018] Preferably, the side of the lower part of the air conditioner body protrudes outward, the inner diameter of the horizontal frame is smaller than the diameter of the lower part of the air conditioner body, and the diameter of the centering hole is equal to the diameter of the lower part of the air conditioner body. When the air conditioner body moves up and down, the lower part of the air conditioner body forms a limiting fit with the horizontal frame and a guiding fit with the centering frame.

[0019] This utility model provides a convenient-to-maintain suspended air conditioning unit. Through the cooperation of the support plate and the snap-fit ​​strip, the air conditioning body can be stably installed on the hoisting frame. During disassembly, simply move the air conditioning body upward so that the pushing component pushes the support plate and contacts the downward movement restriction of the snap-fit ​​strip to remove the air conditioning body. There is no need for manual climbing to disassemble, which facilitates the maintenance and replacement of the air conditioning body. Attached Figure Description

[0026] like Figures 1 to 3 As shown, this utility model embodiment provides a ceiling-mounted air conditioning unit that is easy to maintain, including an air conditioning body 1 and a ceiling-mounted frame 2;

[0027] The hoisting frame 2 includes a ring-shaped horizontal frame 21 and a vertical frame 22 for suspending and fixing the horizontal frame 21;

[0028] The top of the horizontal frame 21 is rotatably connected to at least one pair of support plates 23. The two support plates 23 in each pair are symmetrically arranged with respect to the vertical central axis of the horizontal frame 21. A snap-fit ​​strip 11 is provided at the upper edge of the side of the air conditioner body 1 corresponding to the position of the support plate 23. The support plate 23 can be snapped under the snap-fit ​​strip 11.

[0029] The rotating part of the support plate 23 is provided with two positioning grooves 231, which are arranged circumferentially around the axis of rotation of the support plate 23. A locking member 24 is slidably connected on the horizontal frame 21. One end of the locking member 24 is engaged with the two positioning grooves 231 in sequence, and the other end extends into the inner hole of the horizontal frame 21. An elastic member is connected between the locking member 24 and the horizontal frame 21. A pushing member 12 is provided on the side of the air conditioner body 1 corresponding to the position of the locking member 24. The pushing member 12 is located below the snap-fit ​​strip 11 and its horizontal protrusion length is greater than that of the snap-fit ​​strip 11.

[0030] The cooperation relationship between the locking strip 11, the pushing member 12, the support plate 23 and the locking member 24 is set such that when the locking member 24 engages with the two positioning slots 231, the support plate 23 is inclined towards the vertical center axis of the horizontal frame 21. When the upper edge of the support plate 23 is engaged below the locking strip 11, the engaging end of the locking member 24 is located between the two positioning slots 231, and the pushing member 12 is located above the horizontal frame 21. The upward movement of the pushing member can push the support plate 23 upward, so that the locking member 24 engages with one positioning slot 231, thereby releasing the downward movement restriction of the air conditioner body 1. The downward movement of the pushing member can push the non-engaging end of the locking member 24, thereby releasing the engagement between the locking member 24 and the positioning slot 231.

[0031] The technical solution of this application will be described in detail below with reference to the embodiments shown in the accompanying drawings.

[0032] In this embodiment, the horizontal frame 21 is a rectangular ring frame formed by L-shaped profiles, and the four corners of the horizontal frame 21 are connected to the upwardly extending vertical frame 22, so that the hoisting frame 2 as a whole has a rectangular frame structure. Preferably, the hoisting frame 2 is made of angle steel.

[0033] In this embodiment, for ease of explanation, only one pair of support plates 23 are provided on the horizontal frame 21, located on the left and right crossbeams of the horizontal plate respectively. In some embodiments, two pairs of support plates 23 may also be included, located on the four crossbeams of the horizontal frame 21 respectively, to improve the stability of the support plates 23 in supporting the air conditioner body 1 and reduce the load on each support plate 23.

[0034] The support plate 23 is rotatably connected to the inner corner of the L-shaped profile of the horizontal frame 21, extends in the same direction as the L-shaped profile, and rotates left and right. The lower edge of the support plate 23 is preferably a cylindrical surface, tangent to both side plates of the L-shaped profile. The support force is provided by the side plates of the L-shaped profile and the pivot of the support plate 23, reducing the stress load on the pivot of the support plate 23.

[0035] Two positioning slots 231 on each support plate 23 are located on the cylindrical surface of the lower edge of the support plate 23, on the side opposite to the center of the horizontal frame 21. Each support plate 23 is provided with a locking element 24, which is J-shaped and slidably connected to the bottom surface of the horizontal frame 21. Its tail extends into the inner hole of the horizontal frame 21, and a telescopic spring is sleeved on it. The hook is located on the outside of the horizontal frame 21, and the horizontal frame 21 has a through hole through which the hook end of the locking element 24 passes, engaging with the positioning slot 231. Under the elastic force of the telescopic spring, the locking element 24 can be engaged into the positioning slot 231.

[0036] In this embodiment, the end face of the hook end of the locking member 24 is an upward-sloping surface, and the lateral length of the slope is greater than the depth of the positioning groove 231, thereby limiting the rotation of the support plate 23 towards the center of the horizontal frame 21 by the locking member 24. When the air conditioner body 1 is not installed with the mounting bracket 2, the locking member 24 engages with one positioning groove 231, locking the position of the support plate 23. At this time, the two support plates 23 are inclined towards each other, and the distance between their upper edges is less than the distance between the corresponding two locking strips 11. When the locking strip 11 pushes the support plate 23 upward, the positioning groove 231 can squeeze out the locking end of the locking member 24, and the other positioning groove 231 gradually approaches the locking end of the locking member 24. When the support plate 23 is pushed by the pusher 12, causing the other positioning groove 231 to engage with the locking member 24, if the air conditioner body 1 is moved downward at this time, the locking member 24 can lock the support plate 23, preventing it from rotating. At this time, the two support plates 23 are still tilted towards each other, but the distance between their upper edges is greater than the distance between the corresponding two snap-fit ​​strips 11 on their lateral outer sides, so as to avoid hindering the downward movement of the air conditioner body 1 and to release the restriction on the downward movement of the snap-fit ​​strips 11.

[0037] The air conditioner body 1 is rectangular in shape. A snap-fit ​​strip 11 is fixed to the upper edge of the left and right sides of the air conditioner body 1, corresponding to the position of the support plate 23. The snap-fit ​​strip 11 extends in the same direction as the support plate 23, and its length is preferably equal to the lateral length of the support plate 23. The protruding length of the snap-fit ​​strip 11 relative to the air conditioner body 1 is greater than the thickness of the upper edge of the support plate 23.

[0038] The pusher 12 is located on the side of the air conditioner body 1, below the snap-fit ​​strip 11, and corresponds to the locking member 24. The protrusion length of the pusher 12 relative to the air conditioner body 1 is greater than the protrusion length of the snap-fit ​​strip 11, but it can pass through the inner hole of the horizontal frame 21 as the air conditioner body 1 moves upward.

[0039] The protruding end face of the pusher 12 and / or the non-clamping end face of the locking member 24 are inclined surfaces, such as... Figure 3 As shown, this is so that when the pusher 12 moves up and down, it can push the locking member 24 horizontally outward of the horizontal frame 21.

[0040] When the upper edge of the support plate 23 is engaged below the locking strip 11, the pusher 12 is positioned above the horizontal frame 21 but not in contact with the support plate 23. At this time, when the air conditioner body 1 is moved upwards, the locking strip 11 releases its downward pressure on the support plate 23, and the pusher 12 contacts the support plate 23 and rotates it. The protrusion length of the pusher 12 is set to be sufficient to rotate the support plate 23 until the locking member 24 engages with the positioning groove 231, but not to rotate the support plate 23 to a vertical position or beyond, thus preventing the support plate 23 from failing to return when the air conditioner body 1 moves downwards. In some embodiments, a torsion spring can also be provided on the pivot of the support plate 23, using the spring force of the torsion spring to replace the weight of the support plate 23 to rotate it, reducing the design precision of the protrusion length of the pusher 12 and ensuring stable rotation of the support plate 23.

[0041] To improve the structural strength and support capacity of the support plate 23, the thickness of the support plate 23 is preferably smaller at the top and larger at the bottom.

[0042] In order to reduce the overall weight of the hoisting equipment, the support plate 23 is provided with several weight-reducing grooves 232 on the side opposite to the vertical center axis of the horizontal frame 21.

[0043] In order not to damage the supporting capacity of the support plate 23, several weight-reducing grooves 232 extend vertically and are arranged horizontally to form a rib-like structure on the support plate.

[0044] To ensure the support plate 23 provides more stable support for the air conditioner body 1, the vertical tilt angle of the support plate 23 is 20-30 degrees when its upper edge is engaged below the snap-fit ​​strip 11. This tilted setting of the support plate 23 helps to provide a clamping force for the air conditioner body 1, making the support more stable. However, an excessively small tilt angle is not conducive to stable support, while an excessively large tilt angle will generate a large bending force on the support plate 23, requiring higher strength. Therefore, in this embodiment, a tilt angle of 20-30 degrees is optimal.

[0045] In the solution described above, when moving the air conditioner body 1, any existing lifting trolley can be used to carry and lift the air conditioner body 1. During installation, the inner hole of the horizontal frame 21 is aligned by visual observation and moving the trolley. Although inconvenient, this solution can still solve the technical problems pointed out in the background of this application.

[0046] To address the inconvenience of centering, this embodiment includes a centering frame 3 below the horizontal frame 21. The bottom surface of the centering frame 3 has a centering hole for the air conditioner body 1 to pass through. The size of the centering hole matches the size between the horizontal outer surfaces of the two pushing members 12. Preferably, the upper surfaces of the locking strip 11 and the pushing members 12 are inclined surfaces facing outwards. When the air conditioner body 1 moves upwards, if it is not aligned with the inner hole of the horizontal frame 21, the edge of the centering hole will contact the inclined surfaces of the locking strip 11 and the pushing strip, pushing the air conditioner body 1, along with the lifting trolley, to move in the direction aligned with the inner hole of the horizontal frame 21, thus guiding the air conditioner body 1 towards centering.

[0047] Alternatively, the bottom surface of the centering frame 3 can be tilted upwards towards the center of the centering hole, serving the same purpose as designing an inclined surface on the upper surface of the snap-fit ​​strip 11 and the pusher 12. The inclined surface contacts the snap-fit ​​strip 11 and the pusher 12, moving the air conditioner body 1 in the direction of aligning with the inner hole of the horizontal frame 21.

[0048] Furthermore, in this embodiment, the lower side of the air conditioner body 1 is designed to protrude outwards, the inner hole size of the horizontal frame 21 is smaller than the size of the lower part of the air conditioner body 1, and the size of the centering hole is equal to the size of the lower part of the air conditioner body 1. When the air conditioner body 1 moves up and down, the lower part of the air conditioner body 1 forms a limiting fit with the horizontal frame 21 and a guiding fit with the centering frame 3.

[0049] In this embodiment, the structure of the centering frame 3 can refer to the structure of the hoisting frame 2, but the centering frame 3 is preferably made of lightweight material, such as aluminum alloy.

[0050] During installation, the suspended air conditioning unit provided in this application is installed by lifting the air conditioning body 1 using a lifting trolley. The locking strip 11 rotates the prefabricated plate until it rotates back and abuts against the bottom of the locking strip 11. Releasing the air conditioning body 1 completes the installation. For disassembly, the same method is used: the air conditioning body 1 is first moved upwards using the lifting trolley until the prefabricated plate is engaged with the locking member 24 and the positioning groove 231. Then, the air conditioning body 1 is lowered. When the pushing member 12 contacts the locking member 24, the locking strip 11 is below the upper edge of the support plate 23. As the air conditioning body 1 continues to move downwards, the pushing member 12 pushes the locking member 24, releasing the locking member 24 from the support plate 23. The support plate 23 rotates towards the center of the horizontal frame 21 and rests on the top edge of the air conditioning body 1. The air conditioning body 1 is then removed, and the support plate 23 rotates under gravity until the locking member 24 engages with another positioning groove 231.

[0051] During the above operations, real-time observation is required. During installation, the upward movement of the air conditioner body 1 should be stopped once the locking strip 11 exceeds the upper edge of the support plate 23 to prevent the pushing component 12 from contacting the support plate 23. During disassembly, the highest position of the pushing component 12 should not be higher than the upper edge of the support plate 23.

[0052] The air conditioning unit of this application does not require manual disassembly at height, which facilitates the maintenance and replacement of the air conditioning unit 1.
