DETAILED DESCRIPTION

[0030] The following is combined with Figure 1-3 This application is described in further detail.

[0031] The present application embodiment discloses a double lateral support structure for heating and ventilation ducts. Figure 1 and Figure 2 , which comprises a first vertical rod 1, a second vertical rod 2, a first transverse rod 3 and a second transverse rod 4. The first vertical rod 1 and the second vertical rod 2 can be installed on the wall by bolts. The second transverse rod 4 is fixedly arranged vertically between the first vertical rod 1 and the second vertical rod 2. The first transverse rod 3 is arranged below the second transverse rod 4. The side wall of the first vertical rod 1 is provided with a first rotation groove 11, and the side wall of the second vertical rod 2 is provided with a second rotation groove 21. The first transverse rod 3 is arranged in the first rotation groove 11 by a rotating shaft, and the first transverse rod 3 can be inserted into the second rotation groove 21. The second vertical rod 2 is provided with an assembly component 5 for assembling the first transverse rod 3 and the second vertical rod 2. Insert the air duct between the first vertical rod 1 and the second vertical rod 2, rotate the first transverse rod 3 to fit into the second rotation groove 21, and then assemble the first transverse rod 3 and the second vertical rod 2 together through the assembly component 5 to complete the assembly. When disassembly is required, release the assembly of the first transverse rod 3 and the second vertical rod 2 through the assembly component 5, and rotate the first vertical rod 1 to disengage from the second rotation groove 21, thereby improving the convenience of assembly and disassembly of the supporting structure and facilitating the installation and disassembly of the air duct.

[0032] To further enhance the ease of assembly, refer to Figure 1 and Figure 2The assembly assembly 5 includes a first assembly rod 51, a second assembly rod 52 and an assembly spring 53. The second vertical rod 2 is provided with a first assembly groove 22 communicating with the second rotation groove 21 along the length direction. The first assembly rod 51 is adapted and slidably arranged in the first assembly groove 22. The bottom wall of the second vertical rod 2 is provided with a second assembly groove 23 along the length direction. The assembly spring 53 is fixedly arranged in the second assembly groove 23. The second assembly rod 52 is adapted and slidably arranged in the second assembly groove 23. The assembly spring 53 connects the inner wall of the second assembly groove 23 and the top wall of the second assembly rod 52. The top wall of the first transverse rod 3 is provided with an assembly hole 31 for the first assembly rod 51 to fit through. A transmission assembly 6 for driving the first assembly rod 51 to move is provided between the first assembly rod 51 and the second assembly rod 52. A connecting rope 25 is fixedly arranged on the bottom wall of the second vertical rod 2. An auxiliary rod 251 is fixedly arranged at one end of the connecting rope 25 away from the second vertical rod 2. The auxiliary rod 251 can be inserted into the second assembly groove 23 and abut against the second assembly rod 52. During assembly, the second assembly rod 52 is pushed upward to slide and compress the assembly spring 53 through the auxiliary rod 251, and the first assembly rod 51 is driven to slide upward through the transmission component 6. Then, the first transverse rod 3 is rotated to insert into the second rotation groove 21, and the auxiliary rod 251 is released. The assembly spring 53 restores and pushes the second assembly rod 52 to slide down. The first assembly rod 51 is driven down through the transmission component 6 and passes through the assembly hole 31 to complete the assembly. The operation is simple and convenient.

[0033] To further enhance the ease of assembly, refer to Figure 1 and Figure 2 The transmission assembly 6 includes a first transmission rack 63, a second transmission rack 64, a first transmission gear 61 and a second transmission gear 62. A transmission groove 24 connecting the first assembly groove 22 and the second assembly groove 23 is provided in the second vertical rod 2. The first transmission gear 61 and the second transmission gear 62 are meshed with each other and are both rotatably arranged in the transmission groove 24.

The second transmission rack 64 is integrally fixedly arranged on the side wall of the second assembly rod 52 and meshes with the second transmission gear 62. When the second assembly rod 52 rises, the second transmission rack 64 drives the second transmission gear 62 to rotate, drives the first transmission gear 61 to rotate, and drives the first assembly rod 51 to rise through the first transmission rack 63. Similarly, when the second assembly rod 52 descends, the first assembly rod 51 also descends synchronously, thereby realizing transmission and being easy and convenient to operate.

[0034] In order to improve the stability of the duct installation, refer to Figure 1 and Figure 3The top wall of the second transverse rod 4 is provided with a sliding groove 41, and a sliding rod 42 is slidably provided in the sliding groove 41. A sliding spring 43 connected to the sliding rod 42 is fixedly provided on the side wall of the sliding groove 41. A block 421 is provided on the top wall of the sliding rod 42 to abut against the top wall of the second transverse rod 4. A connecting groove 32 is provided on the side wall of the first transverse rod 3, and a connecting block 422 that can be adapted to be inserted into the connecting groove 32 is fixedly provided on the bottom wall of the sliding rod 42. An installation rope 26 is provided on the side of the second transverse rod 4, and a connecting bolt 261 that can be mounted on the wall is fixedly provided at one end of the installation rope 26 away from the second transverse rod 4. The first transverse rod 3 and the second transverse rod 4 press against the air duct from the upper and lower directions, and the sliding rod 42 presses against the air duct from the left and right directions under the push of the sliding spring 43, thereby improving the stability of the air duct installation.

[0035] The implementation principle of the double lateral support structure of the heating and ventilation duct in the embodiment of the present application is as follows: when installing the duct, the duct is passed through the first assembly rod 51 and the second assembly rod 52 through other lifting devices, and the second assembly rod 52 is pushed upward and the assembly spring 53 is compressed through the auxiliary rod 251. In this process, the second transmission rack 64 moves upward to drive the second transmission gear 62 to rotate, and the second transmission gear 62 rotates to drive the first transmission gear 61 to rotate, and the first transmission gear 61 rotates to drive the first assembly rod 51 to rise through the first transmission rack 63. Then the first transverse rod 3 is rotated to insert into the second rotation groove 21, and then the auxiliary rod 251 is released, and the assembly spring 53 is restored to push the second assembly rod 52 downward. In this process, the second assembly rod 52 moves downward to drive the first assembly rod 51 downward through the transmission assembly 6 and passes through the assembly hole 31 on the first transverse rod 3, so that the first transverse rod 3 and the second vertical rod 2 are assembled together, thereby completing the installation of the duct.

[0036] When disassembly is required, first use other equipment to support the bottom of the air duct, push the second assembly rod 52 through the auxiliary rod 251 to compress the assembly spring 53, and drive the first assembly rod 51 to move up and disengage from the assembly hole 31 through the transmission assembly 6. At this time, the first horizontal rod 3 can be rotated to disengage from the second rotation groove 21, and then the air duct can be taken out from between the first vertical rod 1 and the second vertical rod 2 to complete the disassembly.

[0037] Compared with the common support structure in which the vertical bars and longitudinal bars are assembled by bolts and nuts, this support structure realizes convenient assembly and disassembly between the first transverse bar 3 and the second vertical bar 2 by rotating the first transverse bar 3 to cooperate with the assembly component 5 and the transmission component 6, thereby improving the convenience of assembly and disassembly.

[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
