Description

Technical Field

[0001] The utility model relates to the technical field of central air conditioning systems, and in particular to a quick installation structure for a new return air distribution network. Background Art

[0002] In the air conditioning ventilation and fire smoke exhaust systems, when installing air vents, the method of drilling holes inside the inner side of the air vent frame and connecting them to the flexible connection and the secondary keel frame is generally adopted; this traditional installation method mainly has the following problems:

[0003] 1. The installation speed is relatively slow, and the labor cost is relatively high.

[0004] 2. Sometimes due to tight construction schedules, the air vents are often not connected to the flexible connection, but the galvanized steel plate frame of the flexible connection is directly sleeved behind the air vent, resulting in air leakage from the air vent and affecting the construction quality.

[0005] 3. When the traditional return air vent is equipped with a filter screen, in order to facilitate the disassembly and cleaning of the filter screen, the inner and outer frame form needs to be adopted. Just like our door, a door hinge is installed on one side to rotate the inner frame to open, and a locking part is installed on the other side to lock the inner frame; by opening the locking part and rotating the inner frame, the inner frame can be rotated out to disassemble the filter screen; however, because the inner frame has a certain thickness, the diagonal dimension of the inner frame is larger than the dimension of the outer side of the inner frame. When the air vent is relatively narrow, when the inner frame door hinge (installed on the side close to the surface of the inner frame) rotates, the inner side of the inner frame (at the diagonal position of the door hinge) will touch the inner side of the outer frame (when the gap is large, the outer side of the inner frame cannot cover the locking part, which will seriously affect the aesthetics of the air vent). Therefore, generally, when the width is less than 150 mm, the hinged return air vent cannot be used, and on the project, it can only be changed to a fixed air vent with a filter screen (in this way, only the air vent can be disassembled to clean the filter screen, but with the traditional installation method, it is extremely difficult to disassemble and assemble the air vent) or increase the size of the air vent (affecting the decoration effect).

[0006] 4. When the construction period is relatively tight, due to the slow construction speed, after the decoration specialty or other relevant specialties occupy the position, it is difficult to relocate the flexible connection or the air vent, resulting in increased costs.

[0007] Therefore, exploring an efficient, fast and quality-guaranteed air vent method can better meet the market demand. Summary of the Utility Model

[0032] Next, the technical solutions in the embodiments of the utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments.

[0033] As Figure 1 shown, the utility model provides a rapid installation structure for a new type of return air distribution network, which includes a flexible connection 12. The flexible connection 12 is connected by biting a thin steel plate at both ends of a hose through a machine. The hose is made of fiberglass cloth, aluminum foil cloth or silicon titanium cloth, etc. The two ends of the flexible connection 12 are respectively connected to the air duct and the air outlet 3.

[0034] A support leg 4 is installed on the outer side of the thin steel plate at the lower end of the flexible connection 12. The support leg 4 abuts against the top of the ceiling board 2, and the support leg 4 serves to support the flexible connection 12. In this embodiment, the ceiling board 2 is a gypsum board or an aluminum alloy board.

[0035] An opening corresponding to the air outlet 3 is formed in the ceiling board 2, and the air outlet 3 is installed at the opening of the ceiling board 2. A tension spring 8 is hung inside the air outlet 3, and the other end of the tension spring 8 is hung inside the thin steel plate at the lower end of the flexible connection 12. Through the pulling force of the tension spring 8, the lower end surface of the air outlet 3 is attached to the ceiling board 2, realizing the rapid installation of the air outlet 3. A sealing strip 5 is installed between the air outlet 3 and the thin steel plate at the lower end of the flexible connection 12, and the sealing strip 5 seals the gap between the two to prevent air leakage.

[0036] In a possible embodiment, the supporting legs 4 are arranged to diffract outward along the thin steel plate at the lower end of the flexible connection 12, and a horizontal end plate is formed at the end of the supporting legs 4 to increase the contact area with the ceiling board 2. Optionally, the supporting legs 4 are made of galvanized steel plates.

[0037] A plurality of support members are arranged in the thin steel plate at the lower end of the flexible connection 12, and a filter net 11 adapted to the thin steel plate at the lower end of the flexible connection 12 is installed on the support members. The filter net 11 is provided with a wire frame. Preferably, the support members are through wires 6, and a plurality of through wires 6 pass through the thin steel plate at the lower end of the flexible connection 12 in parallel, and the filter net 11 is placed on top of the through wires 6. The tension spring 8 is hung on the wire frame of the filter net 11, and the filter net 11 is fixed on the through wires 6 by the elastic tension of the tension spring 8. At the same time, the through wires 6 can pass through the supporting legs 4, and nuts 7 are fixed at the ends of the through wires 6 to fix the supporting legs 4 outside the thin steel plate at the lower end of the flexible connection 12. In this embodiment, the through wires 6 not only fix the supporting legs 4 but also fix the filter net 11.

[0038] The air outlet 3 is made of metal, and a hanging part extending inward is formed at the top of the air outlet 3. The two ends of the tension spring 8 are respectively hung on the wire frame of the filter net 11 and the hanging part of the air outlet 3. The tension of the tension spring 8 makes the installation end face of the air outlet 3 closely fit on the ceiling board 2.

[0039] The application of the tension spring 8 in installing the air outlet 3 plays a role in fixing the air outlet 3 to a proper position and effectively solves the problem of improper installation of the air outlet 3 under complex on-site conditions.

[0040] In a possible embodiment, a light keel is fixed on the top of the ceiling board 2. The light steel keel 1 is a galvanized C-shaped steel, and the light keel is arranged along the through holes on the ceiling board 2.

A short pipe with a flange can be connected at the opening of the air duct to facilitate the connection between the short pipe and the air duct. The short pipe is made of galvanized steel plate, the short pipe is arranged vertically downward, and the short pipe is hermetically connected to the air duct to prevent air leakage.

[0043] The thin steel plate of the flexible connection 12 is sleeved on the short pipe and fixedly connected to the short pipe. Specifically, a pressing strip 10 is installed on the outer side of the thin steel plate of the flexible connection 12. The pressing strip 10 is made of galvanized steel plate. The pressing strip 10 presses the thin steel plate of the flexible connection 12 on the short pipe, and the pressing strip 10 is fixed on the short pipe through self-tapping screws 9 to realize the fixation of the flexible connection 12 and the short pipe. At the same time, the flexible connection 12 and the short pipe can also be connected in other ways, such as flanges are provided at the connection parts of both, and they are fixed by bolts. Of course, there can be other connection methods, which will not be elaborated too much here.

[0044] In addition, a flange structure can be directly provided at the thin steel plate of the flexible connection 12, and the flange structure is directly fixedly connected to the opening of the air duct, such as being fixed by bolts; at the same time, a quick-release structure can be provided between the two to realize quick detachable connection through the quick-release structure.
