[0024] The following specific embodiments are used to describe the technical solution of the utility model in detail. The following specific embodiments can be combined or replaced with each other according to actual conditions, and the same or similar concepts or processes may not be described in detail in some embodiments.

[0025] The utility model provides a louver tent which is easy to open and close, comprising a tent surface 3, a column 1 and a plurality of supporting beams 2 installed above the column to form a mounting frame, the tent surface 3 being installed in the mounting frame, the tent surface 3 being composed of a plurality of sunshades 302 arranged side by side, each sunshade 302 being hinged to the supporting beam 2, a first transmission rod 201 being further provided on the supporting beam 2, the sunshades 302 being transmission connected via the first transmission rod 201, the column 1 being provided with a second transmission rod 101, the first sunshade 301 close to the column being transmission connected to the front end of the second transmission rod 101, a worm gear 102 and a worm 103 transmission connected to the worm gear 102 being provided at the rear end of the second transmission rod 101, the worm 103 being externally connected to the worm gear 102, and a crank 104 being externally connected to the worm 103.

[0026] like Figures 1 to 2As shown in the figure, the utility model transfers the opening device of the awning to the column 1 by designing a second transmission rod 101 on the column 1 and drivingly connecting the first sunshade 301 close to the column 1 to the front end of the second transmission rod 101, making it easier for users to open the awning and reducing the occupation of the space inside the awning so that more items can be placed inside the awning; the worm gear 102 and the worm 103 have self-locking property, and a worm gear 102 and a worm 103 drivingly connected to the worm gear 102 are provided at the rear end of the second transmission rod 101, which can prevent the awning from loosening and suddenly closing after it is opened; and the crank 104 externally connected to the worm 103 can facilitate the user to open the awning with less force.

[0027] It can be understood that the crank 104 and the worm 103 are detachably connected. After the user opens the awning, the crank 104 can be removed to prevent children from being injured by hitting the crank 104 when entering and exiting, and the overall aesthetic appearance of the awning can be improved after the crank 104 is stored. When it is necessary to use, the crank 104 can be installed. Specifically, a special-shaped hole is provided at one end of the worm close to the crank, and a special-shaped column adapted to the special-shaped hole is provided on the crank.

[0028] Specifically, an arc-shaped hook rod 106 is provided at the front end of the second transmission rod 101, and the second transmission rod 101 is drivingly connected to the first sunshade through the arc-shaped hook rod 106. When the user rotates the crank 104, the worm 103 drives the worm gear 102 to move the second transmission rod 101 downward. Then, the second transmission rod 101 drives the arc-shaped hook rod 106 downward, and the arc-shaped hook rod 106 drives the first sunshade 301 to rotate, so that the first transmission rod 201 drives all the sunshades 302 to rotate to form a complete sunshade surface. Since the second transmission rod 101 is located on the column 1 and is not perpendicular to the first sunshade 301, by providing an arc-shaped hook rod 106 at the front end of the second transmission rod 101 and drivingly connecting the second transmission rod 101 to the first sunshade 301 through the arc-shaped hook rod 106, it can ensure that the force of the second transmission rod 101 can be effectively transmitted to the first sunshade 301. It can be understood that the second transmission rod 101 and the first sunshade 301 may not be drivingly connected by the arc-shaped hook rod 106, and the second transmission rod 101 can be directly connected to the first sunshade 301 obliquely.

[0029] Specifically, as Figure 3 shown in the figure, a rocker arm 105 is provided on the worm gear 102, and the worm gear 102 is drivingly connected to the second transmission rod 101 through the rocker arm 105. The worm gear 102 can rotate the rocker arm 105, thereby driving the second transmission rod 101 to move up and down. Of course, the rocker arm 105 can also be cancelled, and the second transmission rod 101 can be hinged on the disk of the worm gear 102, not coinciding with the center of the disk, and the above effect can also be achieved.

[0030] Specifically, as Figure 4As shown in the figure, water baffle plates are provided at the left and right ends of the sunshade panel 302. When the sunshade panel 302 is opened, the water baffle plates 303 of two adjacent sunshade panels 302 are in contact with each other. Water baffle plates 303 are provided at the left and right ends of the sunshade panel 302, which can prevent water from accumulating at the top of the sunshade panel 302 when it rains. When the sunshade panel 302 is opened, the water baffle plates 303 of two adjacent sunshade panels 302 are in contact with each other, which can effectively prevent rainwater from flowing into the louver awning and avoid disturbing the users inside the louver awning.

[0031] Specifically, a drainage groove 202 is provided on the support beam 2, and the port of the water baffle plate 303 is located above the drainage groove 202. Since the sunshade panel 302 is located in the middle of the frame formed by the support beams 3, a drainage groove 202 is provided on the support beam 2, and the port of the water baffle plate 303 is located above the drainage groove 202, which can effectively drain the rainwater at the top of the louver awning and form a complete drainage system. It can be understood that drainage holes can also be added at both ends of the support beam 2 to facilitate the drainage of rainwater more.

[0032] Specifically, an installation groove 107 is provided in the column 1, and the second transmission rod 101 and the worm 103 are installed in the installation groove 107. By providing an installation groove 107 in the column and installing the second transmission rod 101 and the worm 103 in the installation groove 107, the second transmission rod 101 and the worm 103 can be prevented from being eroded by rainwater, and the second transmission rod 101 and the worm 103 can be prevented from being damaged, resulting in the failure of the mechanical structure to operate.

[0033] In this embodiment, the support beam 2 forms a square frame, and columns 1 are respectively provided at the four corners of the square frame. The second transmission rod 101 is arranged in one of the columns 1, and the first transmission rod 201 is arranged in the support beam 2 connected to the column 1. The support beam 2 forms a square frame, which can make the interior of the louver awning have a larger space and can accommodate more users or place more items.

[0034] Specifically, the sunshade panels 302 have the same length. When opened, the sunshade panels 302 are in contact with each other to form a complete sunshade surface. This increases the uniformity of the sunshade panels 302, reduces the manufacturing difficulty, and reduces the manufacturing cost of the sunshade panels 302.

[0035] In another embodiment, the support beam 2 forms a triangular frame, and columns 1 are respectively provided at the three corners of the triangular frame. The second transmission rod 101 is arranged in one of the columns 1, and the first transmission rod 201 is arranged in the support beam 2 connected to the column 1. Since a triangle is the most stable geometric shape, the louver awning with a triangular frame can remain stable under the action of wind or other external forces and is not easily blown over or damaged.

[0036] It can be understood that in addition to the above two shapes of louver awnings, this design can also be applied to louver awnings with polygonal frames such as parallelogram frames and pentagonal frames.

[0037] In addition to the above preferred embodiments, the present utility model has other implementation manners. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the scope protected by the present utility model.
