Description

Tent with center-driven long louver canopy opening and closing structure

Technical field

The invention belongs to the field of outdoor products, and in particular relates to a tent with a centrally driven long louvered roof opening and closing structure.

Background technique

There are several ways to fix the louver of the louver top tent on the market: 1. The louver is assembled on a rotating part, and the rotating part is installed on the inner side of the tent ring beam by a pin screw; 2. On the louver profile There is a small tube, one end of the pin shaft is assembled with this small tube, and the other end is inserted into the inner side of the tent ring beam, or a fixing part is installed on the inner side of the tent. The pin shaft and the fixing part can be rotated and assembled; Holes are punched on the inner side of the ring beam. Since a certain number of louvers are required on the top of the tent, a certain number of rows of holes must be punched on the ring beam (the distance between the holes and the holes is the same), and the rows of holes need to be assembled with pin screws or fixing parts. The blind rivet nut; this kind of process has the following drawbacks: 1. High production accuracy requirements, for example, there are 30 rows of holes, if the error of each hole distance is 0.1 mm, the cumulative error of the last hole will be 3 mm; 2. , Each hole needs to be assembled with a blind rivet nut, and the louver rotating part or fixed part is assembled on the ring beam by pin screws or screws.
