Beneficial effect:

The new type of tent in the invention does not need to be assembled, and the structure is unfolded and fixed to the ground well, and the tent cloth is fastened, which is completed, and the operation is simple; the canopy in the form of double-slope drainage is formed by using the cable to find the slope, and it can still be used safely in rainy and snowy weather; through The design of the asymmetrical scissor unit at the top converts the force of the cables on the structure from horizontal to vertical, avoiding the closure of the structure after the cables are stressed.

The structure tent of the utility model can not only meet the needs of people for temporary rest and entertainment, but also has the advantages of no need for assembly, small volume after folding, portability, stability, etc., and is a must-have product for outdoor activities.
