Description

Technical Field

[0001] The utility model belongs to the field of vent protection, in particular to a refrigeration and air conditioning vent protection device. Background Art

[0002] Central air conditioning is a type of refrigeration air conditioning system, consisting of one or more cold and heat source systems and multiple air conditioning systems. Unlike traditional refrigerant air conditioners, such as stand-alone units, VRV centrally processes air to meet comfort requirements and uses the principle of liquid vaporization refrigeration to provide the required cooling capacity for the air conditioning system. In restaurants, a central air conditioner is usually equipped with multiple vents. Existing vents cannot be closed individually. When the temperature in a certain location is relatively low, the corresponding vent cannot be closed, resulting in a poor dining experience for customers in that location. Therefore, we designed a refrigeration air conditioning vent protection device that can seal the vents. Utility Model Content

The two sides of the air guide plates 4 are arc-shaped. The front and rear sides of the air guide plates 4 are in sliding contact with the inner side of the fixed frame 1. Several air guide plates 4 can close the fixed frame 1. When the several air guide plates 4 are in a horizontal state, the adjacent air guide plates 4 are in contact, and the air guide plates 4 on both sides are in contact with the inner side of the fixed frame 1. Touch, close the fixed frame 1, the air guide plate 4 is fixedly installed on the rotating shaft 5, the rotating shaft 5 is rotatably installed on the fixed frame 1, one end of the rotating shaft 5 extends out of the fixed frame 1, and several reserved holes are provided on the fixed frame 1. The rotating shaft 5 is rotatably installed in the corresponding reserved holes through bearings and extends out of the reserved holes. One end of the rotating shaft 5 extending out of the fixed frame 1 is fixedly installed with a coaxial worm gear 6, and one side of several worm gears 6 is meshed and matched with the same worm 7, which is rotatably installed on the fixed frame 1. The outer periphery of both ends of the worm 7 is rotatably connected to the inner hole of the shaft seat through bearings, and the shaft seat is fixedly installed on the fixed frame 1. The utility model has a simple structure and an ingenious design. It does not require any improvement to the existing vents and can be directly installed at the existing vents. It can close the vents and guide the wind discharged from the vents. It is simple to operate, can meet actual needs, and is suitable for promotion. When using the utility model, first hang the hook 3 on the horizontal plate or vertical plate at the vent, control the clamping device to clamp it, at this time the clamping device cooperates with the hook 3 to install the fixed frame 1 to the vent, rotate the worm 7, the worm 7 drives the worm wheel 6 to rotate, the worm wheel 6 drives the corresponding rotating shaft 5 to rotate, the rotating shaft 5 drives the corresponding air guide plate 4 to rotate, and changes the angle of the air guide plate 4. When the vent needs to be closed, the air guide plate 4 is rotated to the horizontal. At this time, several air guide plates 4 can cooperate to close the vent; when it is necessary to guide the wind to the side, the air guide plate 4 is rotated to the left or right. When it is rotated to the appropriate angle, stop rotating the worm 7. When it is necessary to blow air vertically downward, the air guide plate 4 is placed in a vertical state.

[0017] Specifically, as shown in the figure, the motor 20 is fixedly mounted on the fixed frame 1 in this embodiment, and the output shaft of the motor 20 is fixedly connected to one end of the worm 7. The output shaft of the motor 20 is coaxially arranged with the worm 7. When the worm 7 needs to be rotated, the motor 20 is started, and the output shaft of the motor 20 drives the worm 7 to rotate.

[0018] Specifically, as shown in the figure, the clamping device of this embodiment includes a threaded rod 30. A threaded hole 31 is provided in each of the fixing plates 2. The threaded rod 30 is threadedly mounted in the threaded hole 31. A clamping plate 32 is rotatably mounted on the threaded rod 30. The clamping plate 32 can only move up and down. After the hook 3 is hung on the horizontal or vertical plate at the refrigeration and air conditioning vent, the threaded rod 30 is twisted, which drives the clamping plate 32 upward, so that the clamping plate 32 engages with the hook 3 and clamps the horizontal or vertical plate, completing the installation.

[0019] Furthermore, as shown in the figure, one end of the threaded rod 30 of this embodiment is fixedly mounted with a hand wheel 40. Rotating the threaded rod 30 by the hand wheel 40 is more convenient and labor-saving.

[0020] Furthermore, as shown in the figure, a battery 50, a controller 51, and a signal receiver 52 are fixedly mounted on the fixed plate 2 of this embodiment. The battery 50, the signal receiver 52, and the motor 20 are all electrically connected to the controller 51, and the signal receiver 52 is coupled to a remote control. The battery 50 provides power to the controller 51, the signal receiver 52, and the motor 20. When the motor 20 needs to be started, the remote control is pressed. The signal receiver 52 receives the information and feeds it back to the controller 51, which then starts the motor 20.

[0021] Furthermore, as shown in the figure, slide bars 60 are fixedly mounted on both sides of the clamping plate 32 in this embodiment, and sliding grooves 61 are formed on the fixed plate 2 corresponding to the clamping plate 32, and the slide bars 60 are slidably mounted in the corresponding sliding grooves 61. When the clamping plate 32 moves up and down, the slide bars 60 slide in the corresponding sliding grooves 61, preventing the clamping plate 32 from rotating with the threaded rod 30, thereby limiting the position of the clamping plate 32.

[0022] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
