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.

[0004] In order to make up for the defects of the prior art, the present invention provides
the following technical solution.
