Description

Technical Field

[0001] The utility model relates to the technical field of HVAC ventilation, in particular to an air outlet operation device. Background Art

[0002] As an important component of the HVAC ventilation system, air outlets have various structures and forms and are widely used in large public places such as theaters, hotel lobbies, restaurants, aisles, shopping malls, and waiting lounges for passengers and airplanes. The air outlet operation devices in the prior art usually have only one set of travel switches, which can open the ventilation opening, but cannot display whether the current state of the air outlet is open or closed, making it inconvenient to use. Summary of the Invention

[0003] The purpose of the utility model is to solve the above technical problems and provide an air outlet operation device with a simple structure, which is convenient for installation, debugging, and daily operation.

[0004] In order to achieve the above technical purpose and meet the above technical requirements, the technical solution adopted by the utility model is: an air outlet operation device, including a panel, a cover plate, and a mounting plate fixed in a box formed by the panel and the cover plate through a bracket. A first travel switch bracket and a second travel switch bracket are arranged on the mounting plate. A travel switch assembly is arranged between the first travel switch bracket and the second travel switch bracket. An operation button is arranged on the travel switch assembly through a hole on the mounting plate. Notches are arranged on both sides of the operation button, corresponding to the contacts on the travel switches on both sides respectively.

[0005] Preferably: a gap matching with the operation button is arranged on the travel switch assembly.

[0006] Preferably: the second travel bracket is connected to the housing through screws, and the housing is arranged on the mounting plate through the bracket.

[0007] Preferably: the mounting plate is connected to the cover plate, the bracket is connected to the panel, and the mounting plate is connected to the bracket through screws.

[0008] Compared with the traditional structure, the beneficial effects of the utility model are: compact structure, small volume, reliable performance. By setting two sets of travel switches, not only can the ventilation opening be opened and closed, but also the state of the air outlet can be directly displayed, which is convenient for operation. It can be directly installed on the wall near the air outlet, facilitating installation, debugging, and daily operation. Description of the Drawings

[0011] The present utility model will be further described below.

[0012] Referring to the attached Figure 1 , an air outlet operating device includes a panel 1, a cover plate 3. An installation plate 4 is fixed in a box body formed by the panel 1 and the cover plate 3 through a bracket 2. A first travel switch bracket 7 and a second travel switch bracket 8 are arranged on the installation plate 4. A travel switch assembly 6 is arranged between the first travel switch bracket 7 and the second travel switch bracket 8. An operation button 5 is arranged on the travel switch assembly 6 through a hole on the installation plate 4. Notches are arranged on both sides of the operation button 5, corresponding to the contacts on the travel switches on both sides respectively.

[0013] In this preferred embodiment, a gap matching with the operation button 5 is arranged on the travel switch assembly 6.

[0014] In this preferred embodiment, the second travel bracket 8 is connected to a housing 9 through a screw, and the housing 9 is arranged on the installation plate 4 through the bracket 2.

[0015] In this preferred embodiment, the installation plate 4 and the cover plate 3, the bracket 2 and the panel 1, and the installation plate 4 and the bracket 2 are all connected through screws.

[0016] During specific implementation, by operating the operation button, the notches on both sides thereof are respectively brought into contact with the contacts on the travel switches on both sides to control the opening and closing of the air vent, and the current state of the air vent, whether it is open or closed, can be displayed, which is convenient to use. This device can be directly arranged on the wall near the air vent, facilitating installation, debugging and daily operation.

[0017] The above embodiments of the present utility model are merely examples clearly illustrating the present utility model, but are not used to limit the protection scope of the present utility model. All equivalent technical solutions also belong to the scope of the present utility model. The patent protection scope of the present utility model shall be defined by each claim.
