Description

Technical Field

[0001] The utility model belongs to the technical field of louver air outlet equipment, and specifically relates to a louver air outlet suitable for atmospheric airflow conditions. Background Art

[0002] In the existing air conditioning and ventilation systems, louver vents play an important role as decorative components of air inlets and outlets. Such louver vents are usually composed of multiple vent blades arranged in parallel, aiming to provide visual shielding effects while ensuring air circulation. However, due to the special design of louver vents, there are a series of technical problems in practical applications. First, in order to achieve the effect of visual shielding, conventional louver vent baffles are often arranged in an inclined manner. Although this arrangement is effective, in order to improve the strength of the vent baffle, it is usually necessary to increase the thickness of the baffle. However, the increase in thickness not only increases the material cost, but also leads to an increase in the vent resistance coefficient, thereby affecting the efficiency of the air conditioning and ventilation system. Secondly, for louver vents with a long length, due to the weight of the baffle itself and the influence of aerodynamics, the baffle is prone to vibrate under the blowing of atmospheric airflow, thereby generating noise. Under long-term action, this vibration not only affects the user's comfort experience, but may also cause damage and deformation of the baffle, thereby reducing its service life.

[0003] Therefore, developing a new type of louver air outlet structure that can not only ensure the visual shielding effect, but also reduce the resistance coefficient, reduce noise and vibration, while simplifying the system structure and reducing maintenance costs has become an urgent problem to be solved in the current air-conditioning and ventilation system field. Utility Model Content

[0004] The purpose of the utility model is to provide a louver vent suitable for large airflow conditions in view of the above shortcomings, so as to solve the problems that the blade thickness of the louver vent in the prior art is relatively large, resulting in a large resistance coefficient of the leaf vent, which is not suitable for large airflow conditions; for louver vents with longer lengths, it is necessary to set fixing rods between the vent blades of each layer, which makes the structure complicated and affects the ventilation effect; the vent blades are prone to vibration and noise under the blowing of large airflow for a long time, and even damage and deformation. In order to achieve the above purpose, the utility model provides the following technical solutions:

[0024] Example:

[0025] See attached Figures 1 to 3 . The present embodiment provides a louver vent suitable for large airflow conditions, including an vent frame 1, a plurality of blades, a tensioning device and a clamping device. A plurality of mounting holes are evenly spaced from top to bottom on both sides of the vent frame 1, and a plurality of single blades 2 are evenly arranged in the vent frame 1. The tensioning device is arranged on both sides of the vent frame 1. Compared with the prior art, the single blades 2 of the specific vent blades are selected to have a thinner thickness and a longer width (such as more than 100 mm). The blades are fixed inside the vent frame 1 through the clamping device of the vent blades, and the clamping device is fixedly connected to the tensioning device through the mounting holes on both sides of the vent frame 1. Preferably, the single blade 2 of the vent blade of the utility model has a longer width, and the single blade 2 can be arranged horizontally in the vent frame 1. It can only be seen through when looking at the single blade 2 horizontally. At other multiple angles, due to the longer width of the single blade 2, a better visual shielding effect can be guaranteed.

[0026] The clamping device of the utility model comprises an upper mounting seat 3 and a lower mounting seat 4. Bolt mounting holes are provided at corresponding positions of the upper mounting seat 3 and the lower mounting seat 4. A fastening structure in which a bolt 5 cooperates with a nut is provided through the bolt mounting hole. Meanwhile, corresponding through holes are also provided on both sides of the single blade 2. During specific installation, the through holes on both sides of the single blade 2 are respectively corresponded to the lower mounting seats 4 of the clamping device on both sides of the air outlet frame 1, so that the through holes are aligned with the bolt mounting holes. Then, the bolt mounting holes of the upper mounting seat 3 are also aligned with the through holes of the single blade 2. The fastening structure in which the bolt 5 cooperates with the nut is matched to clamp the single blade 2 between the upper mounting seat 3 and the lower mounting seat 4. Since the width of the single blade 2 is relatively long, it is preferred that a plurality of bolt 5 nut matching fastening structures are evenly arranged along the width direction of the single blade 2, preferably four. Four through holes are also correspondingly arranged on one side of the single blade 2, and the bolt mounting holes on the upper and lower mounting seats 4 are matched to ensure that the clamping force on each part of the single blade 2 is uniform.

[0027] The tensioning device specifically includes a screw 6 and a nut matching structure, one end of the screw 6 passes through the mounting hole on the side of the air outlet frame 1 and is fixedly connected to the clamping device on the inner side of the air outlet frame 1, and the other end of the screw 6 is located on the outer side of the air outlet frame 1 and connected by a nut. The tensioning device of each layer of single blades 2 of the preferred air outlet blades is composed of two screws 6 and a nut matching structure, which are evenly arranged along the width direction of the single blade 2. During the working process of the tensioning device, the nuts on both sides of the air outlet frame 1 are screwed so that the screw 6 moves toward the outside of the air outlet frame 1 relative to the air outlet frame 1, and the movement of the screw 6 drives the clamping device to move toward the side of the air outlet frame 1, thereby realizing the movement of the two ends of the single blade 2 toward the side of the air outlet frame 1 respectively, and then tightening the single blade 2. When the tightened single blade 2 is blown by the airflow, the resistance coefficient is small, and it is not easy to shake, which reduces the generation of noise, and the structural bearing capacity of the tightened single blade 2 is also stronger, more durable, thereby extending the service life of the single blade 2. At the same time, in order to prevent the tuyere frame 1 from being easily deformed when subjected to force, reinforcing ribs are provided on the tuyere frame 1.

[0028] Preferably, when the louver air outlet is arranged in different positions, a corresponding appropriate angle is required, and the upper and lower mounting seats 4 of the clamping device are arranged horizontally, and the single blade 2 is also arranged horizontally. The upper and lower mounting seats 4 are arranged tilted, and the single blade 2 is also tilted together with the clamping device. In order to adapt to the needs of the angle setting of the single blade 2 in different scenarios, the mounting holes on both sides of the air outlet frame 1 are replaced with a vertically arranged waist hole structure. The width of the waist hole is larger than the diameter of the tensioning device screw 6, and the nut cannot be completely passed through. Such a setting can change the angle of the single blade 2 by adjusting the angle of the clamping device. The setting of the waist hole can facilitate the up and down movement of the screw 6 when adjusting the angle, and the width of the waist hole is larger than the diameter of the screw 6. It can compensate that when the two screws 6 are adjusted to an inclined position, the two screws 6 can still pass through the waist hole and cooperate with the nut to achieve the tensioning effect.

[0029] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
