Description

Technical Field

[0001] This utility model belongs to the field of air conditioning unit technology, specifically relating to a multi-split air conditioning unit chassis. Background Technology

[0002] Multi-split air conditioning units are widely used in commercial buildings (such as office buildings and shopping malls), residential homes, and industrial auxiliary spaces due to their advantages such as flexible adjustment and energy efficiency. As the core load-bearing component of the unit, the chassis not only needs to support heavy components such as the compressor and condenser of the outdoor unit, but also needs to cope with the continuous vibration generated during the operation of the unit, the intrusion of dust and impurities from the external environment, and the flexible adaptation requirements under different installation scenarios.

[0003] The chassis of some multi-split air conditioning units currently on the market have the following technical defects:

[0004] Insufficient structural strength: Most chassis are formed by a single sheet metal without any targeted reinforcement structure. After long-term bearing of heavy components, they are prone to bending and deformation, which affects the installation accuracy and service life of the unit.

[0005] Inconvenient connection of multiple chassis: When multiple units need to be installed or the units are large and require multiple chassis for support, the existing chassis lack standardized connection structures. Usually, on-site welding or additional connectors are required, which is cumbersome and the connection stability is poor, making it difficult to meet the support requirements of different installation methods. Utility Model Content

[0006] The purpose of this utility model is to provide a multi-split air conditioning unit chassis to solve the problems mentioned in the background art, such as insufficient structural strength and inconvenience in connecting multiple chassis in some current multi-split air conditioning unit chassis on the market.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-split air conditioning unit chassis, comprising a chassis body and an annular reinforcing edge fixed to the surface of the chassis body, wherein the annular reinforcing edge is fixed with intersecting horizontal and vertical reinforcing ribs, and the surface of the annular reinforcing edge is provided with a groove, wherein a shock-absorbing pad is fixed in the groove.

[0008] The chassis body is provided with multiple connecting mechanisms, each consisting of a connecting column and an adjusting block. The adjusting block is fixed to one end of the connecting column. The outer wall of the connecting column is provided with a threaded groove 1 and a threaded groove 2. Two threaded holes are provided on each of the four outer walls of the chassis body, and the threaded holes on the outer wall of the chassis body match the threaded groove 2 on the outer wall of the connecting column. A protective plug is inserted into the threaded hole.

[0009] In a further embodiment, a support block is externally threaded to the threaded groove on the outer wall of the connecting column, and the support block is fixedly connected to the bottom plate of the chassis body. A second support block is movably connected to the outer wall of the connecting column, and the second support block is fixedly connected to the bottom plate of the chassis body.

[0010] In a further embodiment, a limit ring is fixed to the outer wall of the connecting column, and a rectangular connecting groove is provided on the end face of the adjusting block.

[0011] In a further embodiment, mounting bosses are fixed at all four corners of the surface of the chassis body, and mounting bases are fixed on the surface of the mounting bosses.

[0012] In a further embodiment, the chassis body has multiple ventilation holes on its outer walls and surface, and metal protective mesh is installed inside the ventilation holes.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] The chassis of this multi-split air conditioning unit has a double-strength structure formed by setting an annular reinforcing edge on the surface of the chassis body and fixing horizontal and vertical reinforcing ribs inside the annular reinforcing edge. This greatly improves the overall rigidity and deformation resistance of the chassis, and can stably support the heavy components of the air conditioning unit for a long time, avoiding chassis bending and deformation caused by load, and extending the overall service life of the unit.

[0015] The connecting mechanism inside the chassis body, in conjunction with the threaded holes around the chassis, eliminates the need for additional welding or connecting parts. Simply by using a tool to rotate the adjusting block, the connecting column can be driven to extend and engage with the threaded holes of another chassis, making the connection process convenient. At the same time, support block one (threaded to the connecting column) can drive the connecting column to move and limit its radial displacement, while support block two (movably connected to the connecting column) can guide the connecting column. The two work together to prevent the connecting column from shifting during movement, ensuring the coaxiality and stability of the multi-chassis connection and meeting the support requirements of different numbers of units and different installation methods.

[0016] The shock-absorbing pads are fixed in the grooves on the surface of the annular reinforcing edge. When the air conditioning unit is connected to the chassis via the mounting base, the shock-absorbing pads can directly adhere to the bottom of the unit. They use their own elasticity to absorb the vibrations generated during the operation of the unit (such as when the compressor is working), reducing the transmission of vibrations to the mounting surface. This reduces resonance noise at the source and improves the acoustic experience of the user's environment. This multi-split air conditioning unit chassis can reduce the noise generated by vibration during the operation of the air conditioning unit, while facilitating the connection of multiple chassis bodies to meet different support requirements.

[0022] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0023] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0024] This utility model provides, for example Figure 1-3The chassis of a multi-split air conditioning unit shown includes a chassis body 1 and an annular reinforcing edge 2 fixed to the surface of the chassis body 1. The annular reinforcing edge 2 has horizontal and vertical reinforcing ribs 3 fixed inside, which can increase the strength of the annular reinforcing edge 2 and improve the stability of the support. The surface of the annular reinforcing edge 2 has a groove, and a shock-absorbing pad 4 is fixed inside the groove. Mounting bosses 5 are fixed at the four corners of the surface of the chassis body 1. Mounting seats 6 are fixed on the surface of the mounting bosses 5, and the mounting seats 6 are connected to the air conditioning unit. At the same time, the shock-absorbing pad 4 is attached to the bottom of the air conditioning unit. When the air conditioning unit is working, it can absorb the vibration generated by the air conditioning unit during operation and reduce the noise of the air conditioning unit during operation. Multiple ventilation holes are opened on the outer walls and surface of the chassis body 1. Metal protective mesh 13 is installed in the ventilation holes. The ventilation holes can ensure airflow and heat dissipation of the air conditioning unit.

[0025] The chassis body 1 is provided with multiple connecting mechanisms, which consist of connecting columns 7 and adjusting blocks 8. There are four connecting columns 7 in total. Two connecting columns 7 are set along the length direction of the chassis body 1, and the other two connecting columns 7 are set along the width direction of the chassis body 1. The height of the two transversely set connecting columns 7 is lower than the height of the two longitudinally set connecting columns 7 to avoid motion interference. The adjusting block 8 is fixed to one end of the connecting column 7. The outer wall of the connecting column 7 is provided with a threaded groove 1 and a threaded groove 2. Two threaded holes are provided on the outer walls of the chassis body 1. The threaded holes on the outer walls of the chassis body 1 match the threaded groove 2 on the outer walls of the connecting columns 7. A protective plug 12 is inserted into the threaded hole.

[0026] The outer wall of the connecting column 7 has a threaded groove connected to a support block 9, which is fixedly connected to the base plate of the chassis body 1. The outer wall of the connecting column 7 has a movably connected support block 11, which is also fixedly connected to the base plate of the chassis body 1. A limit ring 10 is fixed to the outer wall of the connecting column 7. The end face of the adjusting block 8 has a rectangular connecting groove. When the two chassis bodies 1 are connected, an external tool is inserted into the rectangular connecting groove of the adjusting block 8 to drive the connecting column 7 to rotate. The threaded groove rotates in the support block 9, causing the connecting column 7 to move, so that one end of the connecting column 7 extends to the outside of the current chassis body 1 and is screwed into the threaded hole of the other chassis body 1, ensuring a stable connection between the two chassis bodies 1. At the same time, the support block 11 supports the connecting column 7 to prevent the connecting column 7 from shifting during movement, ensuring connection accuracy. The support block 9 can restrict the position of the adjusting block 8 and the limit ring 10, preventing the threaded groove on the connecting column 7 from separating from the support block 9.

[0027] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0028] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] Working principle:

[0030] The chassis of this multi-split air conditioning unit is determined first based on the installation location and dimensions of the air conditioning unit, deciding whether to use a single chassis or a combination of multiple chassis:

[0031] Single chassis installation and unit fixing: The air conditioning unit is connected to the mounting bases 6 at the four corners of the chassis body 1 using bolts and other fasteners. After the unit is fixed, the horizontal and vertical intersecting reinforcing ribs 3 in the annular reinforcing edge 2 provide stable support for the chassis, bear the weight of the unit, and prevent the chassis from deforming.

[0032] When the unit is running, the vibration generated by the compressor and other components is transmitted to the chassis. At this time, the shock-absorbing pad 4 in the groove of the annular reinforcing edge 2 absorbs the vibration energy through its own elastic deformation, reduces the transmission of vibration to the mounting surface (ground, bracket), and avoids the generation of resonance noise.

[0033] Multi-chassis connection operation: When multiple chassis need to be combined for support, remove the protective plug 12 from the threaded hole on the outer wall of the chassis to be connected. Use an external tool to insert into the rectangular connecting groove on the end face of the adjusting block 8. Rotate the adjusting block 8 to drive the connecting column 7 to rotate synchronously. The threaded groove one on the outer wall of the connecting column 7 and the support block one 9 (fixed to the chassis base plate) form a threaded engagement. During the rotation, the connecting column 7 extends out of the chassis body 1 along the axial direction. Align the extended connecting column 7 with the threaded hole at the corresponding position of the other chassis. Continue to rotate the adjusting block 8 so that the threaded groove two of the connecting column 7 is threadedly connected to the threaded hole of the other chassis until the two chassis fit tightly together. During this process, the support block two 11 (fixed to the chassis base plate) guides the connecting column 7 to prevent it from shifting when moving, ensuring connection accuracy. The limiting ring 10 on the outer wall of the connecting column 7 cooperates with the support block one 9 to prevent the threaded groove one of the connecting column 7 from disengaging from the support block one 9 due to excessive rotation, ensuring connection stability.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
