Description

Technical Field

[0001] This utility model relates to the field of air conditioning equipment technology, and in particular to an adjustment device and a ceiling-mounted air conditioning unit. Background Technology

[0002] When the motor of an existing ceiling-mounted air conditioner is running, if the motor vibration is the same as the natural frequency of the housing, resonance will occur, which will amplify the noise. Due to the poor consistency of different components (such as motor feet, chassis, and motor body), it is difficult to unify the natural frequencies of different units. It is difficult to effectively adjust the housing stiffness on site to eliminate resonance. In addition, the housing condition is prone to change during transportation or operation. Once resonance occurs, after-sales service is difficult. Existing technology lacks a structure that can adjust the housing stiffness on site, making it impossible to quickly and accurately adjust to match the actual working conditions, which makes it difficult to completely solve the noise problem. Utility Model Content

[0003] The main objective of this utility model embodiment is to provide an adjustment device and a ceiling machine, aiming to improve the technical problem that the rigidity of the housing of the ceiling machine is not easy to adjust in the prior art.

[0004] An embodiment of this utility model provides an adjustment device, disposed on the housing of a ceiling machine, comprising:

[0005] The first cover is connected to one side of the ceiling machine housing to form a first accommodating cavity;

[0006] The second cover is disposed in the first accommodating cavity and is connected and cooperated with the ceiling machine housing to form the second accommodating cavity;

[0007] The movable component passes through the second cover and the first cover in sequence and is threadedly connected to the second cover and the first cover. One end of the movable component located in the second accommodating cavity is provided with a limiting part, which is configured to abut against the second cover when it moves to the top of the second accommodating cavity.

[0008] In some embodiments, the first cover is provided with a first threaded hole, and the second cover is provided with a second threaded hole, wherein the first threaded hole and the second threaded hole are aligned.

[0009] The movable component is a lead screw, which passes through the second threaded hole and the first threaded hole in sequence. One end of the lead screw is located in the second accommodating cavity, and the other end of the lead screw protrudes from the end of the second cover away from the ceiling machine housing. The limiting part is provided at the end of the lead screw located in the second accommodating cavity, and the width of the limiting part is greater than the width of the second threaded hole.

[0010] In some embodiments of this utility model, the first cover has a protrusion on the side away from the ceiling machine housing, the first threaded hole extends from the side of the first cover near the second cover to the protrusion and passes through the protrusion, and one end of the lead screw protrudes from the protrusion.

[0011] In some embodiments of this utility model, the first cover includes a first cover portion and a first folded edge portion disposed around the edge of the first cover portion, and the first folded edge portion is connected to the ceiling machine housing.

[0012] In some embodiments of this utility model, a polygonal blind hole is provided at the end of the lead screw away from the ceiling machine housing.

[0013] In some embodiments of this utility model, the second cover includes a second cover portion and a second folded edge portion disposed around the edge of the second cover portion, and the second folded edge portion is connected to the ceiling machine housing.

[0014] In some embodiments of this utility model, the second cover portion is circular, and the width of the second folded edge portion is greater than the radius of the second cover portion and less than the diameter of the second cover portion.

[0015] In some embodiments of this utility model, the second cover is further provided with a plurality of weight-reducing grooves, and the plurality of weight-reducing grooves are distributed in a ring array along the center of the second cover.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure).

[0030] like Figures 1-5 As shown, this utility model provides an adjustment device 20, which is disposed on the ceiling machine housing 10. The adjustment device 20 includes a first cover 100, a second cover 200, and a movable member 300. The first cover 100 is connected to one side of the ceiling machine housing 10 to form a first receiving cavity. The second cover 200 is disposed in the first receiving cavity and is connected to the ceiling machine housing 10 to form a second receiving cavity. The movable member 300 passes through the second cover 200 and the first cover 100 in sequence and is threadedly connected to the second cover 200 and the first cover 100. A limiting part 310 is provided at one end of the movable member 300 located in the second receiving cavity. The limiting part 310 is configured to abut against the second cover 200 when it moves to the top of the second receiving cavity.

[0031] It should be noted that the limiting part 310 is configured to abut against the second cover 200 when it moves to the top of the second accommodating cavity. That is, the limiting part 310 moves toward the first cover 100 along with the movable member 300, but the width of the limiting part 310 is greater than the through hole of the movable member 300, so that it abuts against the top wall of the second cover 200 when it moves to the top of the second accommodating cavity.

[0032] Since both the first cover 100 and the second cover 200 are connected to the ceiling machine housing 10, the movable part 300, which is threadedly connected to the first cover 100 and the second cover 200, can rotate and move along its axial direction. When the movable part 300 rotates in the first direction, it moves toward the ceiling machine housing 10 until it abuts against the ceiling machine housing 10. When the movable part 300 continues to rotate in the first direction, it will press against the ceiling machine housing 10, thereby causing... The ceiling housing 10 deforms, thereby changing its rigidity. When the movable part 300 rotates in the second direction (the second direction is opposite to the first direction), the movable part 300 moves toward the first cover 100 until the limiting part 310 abuts against the top wall of the second cover 200. The movable part 300 continues to rotate in the second direction, and the limiting part 310 will cause the ceiling housing 10 to deform through the second cover 200, thereby changing its rigidity.

[0033] It is understood that the adjustment device 20 is threadedly connected to the first cover 100 and the second cover 200 via the movable part 300. By rotating the movable part 300, it can move relative to the first cover 100 toward the ceiling machine housing 10 until it presses against the ceiling machine housing 10 and deforms it, thereby changing its stiffness. Alternatively, it can move relative to the first cover 100 away from the ceiling machine housing 10, causing the first cover 100 to drive the ceiling machine housing 10 to deform and change its stiffness. That is, this utility model can change the stiffness of the ceiling machine housing 10 through the movement of the movable part 300, making it convenient for installers to adjust the stiffness of the ceiling machine and eliminate resonance.

[0034] In some embodiments, the first cover 100 is connected to the ceiling machine housing 10 by screws, and the second cover 200 is also connected to the ceiling machine housing 10 by screws.

[0035] In some embodiments, the orthographic projection of the first cover 100 onto the ceiling housing 10 completely covers the second cover 200.

[0036] It should be noted that the orthographic projection of the first cover 100 completely covers the second cover 200, which ensures that the second cover 200 can be completely contained in the first accommodating cavity formed by the first cover 100 and the ceiling machine housing 10. On the one hand, this ensures that the second cover 200 is not affected by external factors, and on the other hand, it avoids the protruding part of the second cover 200 from affecting the overall aesthetics of the ceiling machine.

[0037] In some embodiments, a first threaded hole 101 is provided on the first cover 100, and a second threaded hole 201 is provided on the second cover 200. The first threaded hole 101 and the second threaded hole 201 are aligned. The movable part 300 is a lead screw, which passes through the second threaded hole 201 and the first threaded hole 101 in sequence. One end of the lead screw is located in the second accommodating cavity, and the other end of the lead screw protrudes from the end of the second cover 200 away from the ceiling housing 10. A limiting part 310 is provided at the end of the lead screw located in the second accommodating cavity. The width of the limiting part 310 is greater than the width of the second threaded hole 201.

[0038] It is understandable that the first threaded hole 101 and the second threaded hole 201 are aligned, that is, the two are aligned, which can avoid the misalignment of the two and increase the resistance of the screw rotation; the width of the limiting part 310 is greater than the width of the second threaded hole 201, that is, the limiting part 310 cannot pass through the second cover 200, but can only abut against the top of the second cover 200, thereby causing the second cover 200 to drive the ceiling machine housing 10 to deform.

[0039] In some embodiments, the first cover 100 has a protrusion 130 on the side away from the ceiling housing 10, and a first threaded hole 101 extends from the side of the first cover 100 near the second cover 200 to the protrusion 130 and passes through the protrusion 130, and one end of the lead screw protrudes from the protrusion 130.

[0040] It is understandable that a protrusion 130 is provided on the first cover 100 and the first threaded hole 101 passes through the protrusion 130 to leave enough length for the rotation of the lead screw, so as to ensure that the movable part 300 can have sufficient movement distance along its axial direction, thereby changing the rigidity of the ceiling machine housing 10.

[0041] For example, the height of the protrusion 130 is greater than or equal to the distance between the top wall of the second cover 200 and the ceiling machine housing 10, so as to ensure that the limiting part 310 moves from the position abutting against the ceiling machine housing 10 to the position abutting against the top wall of the second cover 200, thereby allowing the lead screw to be rotated in two directions to increase or decrease the rigidity of the ceiling machine housing 10.

[0042] In some embodiments, the first cover 100 includes a first cover portion 110 and a first folded edge portion 120 disposed around the edge of the first cover portion 110, the first folded edge portion 120 being connected to the ceiling housing 10.

[0043] For example, the first cover portion 110 has a rectangular structure, and each of the four edges of the first cover portion 110 is provided with a first folded edge portion 120, which is connected to the ceiling housing 10 by screws.

[0044] It should be noted that the first cover part 110 has a rectangular structure, that is, the orthographic projection of the first cover part 110 on the ceiling machine housing 10 is a rectangle.

[0045] In some embodiments, a polygonal blind hole is provided at the end of the lead screw away from the ceiling machine housing 10.

[0046] For example, the polygonal blind hole is generally a regular hexagonal blind hole, which facilitates the adjustment of the position of the limiting part 310 by rotating the lead screw with a hexagonal wrench.

[0047] In some embodiments, the second cover 200 includes a second cover portion 210 and a second folded edge portion 220 disposed around the edge of the second cover portion 210, the second folded edge portion 220 being connected to the ceiling housing 10.

[0048] For example, the second folded edge 220 is connected to the ceiling housing 10 by screws.

[0049] Alternatively, if the second cover portion 210 is a circular structure, then the second folded edge portion 220 is an annular structure. If the second cover portion 210 is a circular structure, then the orthographic projection of the second cover portion 210 on the ceiling housing 10 is a circle.

[0050] In some embodiments, the second cover portion 210 is circular, and the width of the second folded edge portion 220 is greater than the radius of the second cover portion 210 and less than the diameter of the second cover portion 210.

[0051] It should be noted that when the second cover portion 210 is circular, in order to ensure the lifting force of the second cover 200 lead screw (i.e., the limiting portion 310 abuts against the top of the second cover 200, and the lead screw continues to rotate in the second direction, the second cover 200 is subjected to the force of the limiting portion 310), if the width of the second folded edge portion 220 is too small, there will not be enough rigidity to pull the ceiling machine housing 10 to deform. If the width of the second folded edge portion 220 is too large, the lifting force of the lead screw will not be effectively transmitted to the ceiling housing.

[0052] In some embodiments, the second cover 200 is further provided with a plurality of weight-reducing grooves 230, which are arranged in a ring array along the center of the second cover 200.

[0053] It is understandable that by setting vibration damping grooves on the second cover 200, the weight of the second cover 200 is reduced, making it easier to install, disassemble, and transport the second cover 200.

[0054] In some embodiments, the present invention also provides a ceiling machine that includes the aforementioned adjustment device 20. Since the ceiling machine has the aforementioned adjustment device 20, that is, includes some or all of the embodiments of the aforementioned adjustment device 20, the corresponding ceiling machine has the beneficial effects of some or all of the embodiments of the aforementioned adjustment device 20.

[0055] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made based on the contents of the present utility model specification and drawings under the application concept of the present utility model, or direct / indirect applications in other related technical fields, are included in the patent protection scope of the present utility model.
