[0002] With the development of network information technology, more and more companies are starting to build large data centers. For the air-conditioning area of ​​the data center, ventilation is a very important issue. Traditional air-conditioning area ventilation grilles have problems such as being unable to adjust or difficult to adjust.

[0003] In order to solve the above-mentioned problems, a patent document with announcement number CN207716629U discloses a single-layer adjustable louver air outlet, including a blade guide plate fixedly mounted on an outer frame in the longitudinal direction, a plurality of evenly arranged limit grooves on the side of the blade guide plate facing the back of the outer frame, a plurality of blades arranged in parallel and rotatably connected to the outer frame in the transverse direction, and one end of the blade close to the front of the outer frame is embedded in the corresponding limit groove. When the airflow direction of the air outlet needs to be adjusted, the blade is pushed to rotate around the blade shaft in the limit groove at a certain angle, so that the airflow direction of the air outlet can be adjusted, and the steel wire wound between the plurality of blade shafts can limit the rotation of the blade shaft, so that the blade after the angle adjustment is not easy to rotate due to the wind force and its own gravity. However, the above technical solution needs to rotate the blades one by one during the blade adjustment process, and the operation process is relatively cumbersome. In addition, the rotation of the blade shaft is limited by the steel wire, which is easy to reduce the limiting effect on the blade shaft after long-term use, causing the blade to loosen.

[0004] Therefore, a louver grille with convenient blade (or louver plate) adjustment is needed to overcome the above-mentioned problems of complicated blade adjustment and loose blades. Utility Model Content

[0018] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1-Figure 3 The adjustable louver grille for the air-conditioning zone shown includes a louver grille body, a driving device, a second long connecting rod 9 and a spring 8 .

[0020] The louver grille body comprises a frame 1, a plurality of transmission plates 7 and a plurality of louver plates 2 arranged inside the frame 1; the frame 1 is a rectangular frame structure, and a plurality of louver plates 2 are arranged vertically inside the frame 1. In this embodiment, Figure 1 Three louvers 2 are arranged on the inner side of the middle frame 1 .

[0021] Two ends of each louver plate 2 are respectively fixedly connected with a transmission sheet 7 .

[0022] The middle part of the transmission plate 7 is also hinged to the frame 1, so that the transmission plate 7 can rotate relative to the frame 1 in the vertical plane; the driving device is arranged on one side of the frame 1, and the second long connecting rod 9 is arranged on the other side of the frame 1. For example, Figure 1 In the embodiment, the driving device is arranged on the right side of the frame 1, and the second long connecting rod 9 is arranged on the left side of the frame 1.

[0023] like Figure 2 As shown, the driving device includes a first long connecting rod 6, a force transmission rod 5, a driving member, a mounting box 4 and a worm gear mechanism with a self-locking property; the mounting box 4 is fixed to one side of the frame 1, and the worm gear mechanism is arranged in the mounting box 4. The worm of the worm gear mechanism is connected to the driving member, and the driving member includes a driving knob 3, and the driving knob 3 is coaxially fixedly connected to the worm. The worm wheel of the worm gear mechanism is eccentrically connected to the force transmission rod 5, and one end of the force transmission rod 5 is eccentrically fixed to the axial end of the worm wheel, so that when the worm wheel rotates, it drives the force transmission rod 5 to rotate around the axis of the worm wheel, and also has a certain displacement in the vertical direction. The force transmission rod 5 is hinged to the first long connecting rod 6, and the vertically displaced force transmission rod 5 drives the first long connecting rod 6 to move vertically synchronously. For example, Figure 2 The first long connecting rod 6 shown rises or falls; the first long connecting rod 6 is hinged to all the transmission plates 7 on one side of the frame 1.

[0024] Specifically, the transmission plate 7 is an L-shaped or 7-shaped metal sheet, and the transmission plate 7 is provided with a first hinge, a second hinge and a third fixed connection member in sequence along its length direction; the first hinge is hinged to the first long connecting rod 6, the second hinge is hinged to the frame 1, and the third fixed connection member is fixedly connected to the louver 2.

[0025] When the manual operation driving knob 3 is rotated, the worm connected to it is driven to rotate, the worm wheel matched with the worm is driven to rotate, and the horizontal force transmission rod 5 is driven to rotate around the axis of the worm wheel in the vertical plane, thereby driving the first long connecting rod 6 to move vertically, and then driving all the transmission plates 7 connected to the first long connecting rod 6 to rotate around the second hinge. If the first long connecting rod 6 rises, the height of the third fixed connecting member is reduced, and the louver 2 is closed. If the first long connecting rod 6 falls, the height of the third fixed connecting member is increased, and the louver 2 is opened. Due to the self-locking characteristics of the worm gear mechanism, the rotation operation of the driving knob 3 is released, the worm wheel cannot rotate, and the louver 2 remains at the opening angle.

[0026] like Figure 3 As shown, the second long connecting rod 9 is hinged to all the transmission plates 7 on the other side of the frame 1; one end of the spring 8 is connected to the second long connecting rod 9, and the other end is connected to the frame 1. One end of the spring 8 is connected to the middle part of the second long connecting rod 9, and the other end is connected to the upper part of the frame 1. The spring 8 and the second long connecting rod 9 can keep the louver 2 stable in the open state.

[0027] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
