The energy folding top supporting mechanism of tent
Technical field
The utility model relates to the energy folding top supporting mechanism of tent.
Background technology
Existing tent top supporting mechanism is mainly divided into two kinds:
The first, as CN2550449Y, the CN201972449U of Chinese patent database bulletin, comprise upper top cover, lower top cover, coil tension spring, some support bars and some hack levers, upper top cover and lower top cover arrange up and down and form can be up and down away from or approaching connection, this coil tension spring connects upper top cover and lower top cover, this support bar pivot joint upper top cover, top cover under this hack lever pivot joint, this hack lever is pivot joint support bar also.Because this mechanism need apply hack lever, therefore there is following shortcoming: 1, cost is high, 2, complex structure, 3, can increase the operating range of upper top cover and lower top cover, cause mechanism's increase that takes up room.
The second, as CN202249141U, the CN103075045A of Chinese patent database bulletin, comprise upper top cover, lower top cover and some support bars, this upper top cover can be flexibly connected lower top cover, top cover under this support bar pivot joint, when upper top cover interlocking is during at lower top cover, upper top cover can cover and connect support bar so that support bar remains on deployed condition, movable upper top cover after pine oil interlocking, can rotary supporting rod with folding.Though this mechanism has saved hack lever, when operation, need first pine oil interlocking, ability closing-folding mechanism after movable upper top cover, operation inconvenience.
