Technical Field

[0001] This utility model belongs to the field of tent technology, and in particular relates to a louvered tent louver rotation locking device. Background Technology

[0002] Most existing tents use a frame structure to support the tarpaulin. There are also louvered tents designed to facilitate the opening and closing of louvers. However, the opening and closing of these louvered tents is basically a manual push-pull structure. Since large tents have many louvers, pushing and pulling requires a lot of force, which is inconvenient for users. Summary of the Invention

[0003] The purpose of this invention is to provide a louver rotation locking device for a louvered tent.

[0004] The purpose of this utility model is to solve the following problem:

[0005] A louvered tent louver rotation locking device includes a rectangular frame formed by two longitudinal beams and two transverse beams fixedly connected, and uprights fixed at the four corners of the rectangular frame and extending downwards. Hinges spaced apart on the two opposite transverse beams of the rectangular frame are hinged to first hinge holes in the center of rotating components. A louver is fixed to the top of each pair of rotating components on the two transverse beams. Second hinge holes at the tail of the first rocker arm extending downwards from the rotating component on each transverse beam are hinged to the same transverse linkage rod. The linkage rod on the two transverse beams is driven to swing synchronously by a longitudinally arranged synchronizing rod, thereby driving the rotation and opening / closing of the louvers through the rotating components. A gearbox is fixed on the longitudinal beams. The synchronizing rod passes through the gearbox, and a worm gear is fixed on the synchronizing rod inside the gearbox. A vertically arranged worm gear, meshing with the worm gear, is hinged inside the gearbox. A rotating handle extending out of the gearbox is connected to the shaft of the worm gear.

[0006] As a further optimization of the above technical solution, a limit block is provided on the gearbox, and a stop block is provided on the synchronizing rod to cooperate with the limit block for limiting.

[0013] The advantages of this invention compared to the prior art are:

[0014] 1. This utility model utilizes a worm gear mechanism to drive the rotation of the louvers, which not only reduces the external force applied when opening and closing the louvers, but also utilizes the self-locking principle of the worm gear mechanism to open the louvers to any permissible position and lock them in order to control the air intake or the brightness inside the tent.

[0015] 2. The rotating handle of this utility model uses a hook and hanging ring connection method to facilitate disassembly, transportation and storage. An anti-slip sleeve or sleeve is provided on the hand grip part of the S-shaped crank handle to facilitate operation.

[0016] 3. The synchronizing rod of this utility model is hinged to the connecting rod and the linkage rod in sequence through the second rocker arm, thereby driving the linkage rod to swing. The transmission structure is simple and convenient.
