TECHNICAL FIELD
[0001] The present invention pertains to the field of outdoor supplies and specifically relates to a tent with a center-driven long louver canopy opening and closing structure.
BACKGROUND ART
[0002] The louver boards of the tents with a louver canopy on the present market are fixed by the following methods: In the first method, louver boards are assembled on a rotating part, and the rotating part is mounted on the inner side face of a ring beam of the tent by means of hinge pin screws; in the second method, a small tube is arranged on a louver board profile, one end of a hinge pin is fit and assembled with the small tube and the other end of the hinge pin is inserted into the inner side face of a ring beam of the tent, or a fixing part is mounted on the inner side face of the tent, and the hinge pin is fit and assembled with this fixing part in a rotatable manner. Such assembly methods all require perforating the inner side face of the ring beam. As the tent canopy needs a certain number of louver boards, a certain number of holes need to be opened on the ring beam (the holes are at the same spacing) and rivet nuts matched with the hinge pin screws or fixing parts need to be assembled on the holes. Such processes have the following defects: 1. The required production precision is high. For example, if there are 30 holes and the error of the spacing between the holes is 0.1 mm, the accumulated error of the last hole will be 3 mm; 2. A rivet nut needs to be assembled on each hole; the louver board rotating parts or the fixing parts are assembled on the ring beam by means of hinge pin screws or screws. This process is tedious, resulting in a high labor cost; 3. After the product has been used for a long time, the hinge pin screws are at risk of falling off after the louver boards have rotated many times, thereby affecting the normal use of the product.
[0003] Next, for an existing tent with a louver canopy, a driving mechanism is arranged on one side of the louver boards in general, the end of each louver board adjacent to a worm gear mechanism is relatively flat in a closed state, while the closure at the other end relies on the drive of the closure of the left end. Due to process limitations, when the length of the pipe reaches a certain amount, it is prone to distortions and other problems, thereby causing failure of complete closure of the right end of the louver board in a closed state and other functional failures.
SUMMARY OF THE INVENTION
[0004] In order to make up for the defects of the prior art, the present invention provides the following technical solution.
