Abstract

A top support structure of tent frame includes a top pivoted holder (1), to which a plurality of support poles (10) are pivotally coupled. A flexible body (9) is set between each support pole and the top pivoted holder. The flexible body folds and stores elasticity energy when the tent frame is folded and automatically shoots the support poles when the elasticity energy is released. A control holder (2) is pivotally coupled to the bottom of the top pivoted holder, and the cotrol holder has lock pieces (211) which can prop the support poles up to limit their rotation and release grooves (212) adjacent to the lock pieces which can release the limitation. On the top of pivoted grooves (12) of the pivoted holder are set position-limited devices (D) to prevent the support poles from rotating upwards.

Description

Top support structure of tent frame

Specification top support structure of tent frame

# Fine or

[1] the present invention relates to a kind of tent member, a kind of top support structure of tent frame is particularly related to.

[2] tent rack of existing a kind of Automatic-expanding, it is mainly at top provided with the pivot connected slot that pivot joint each support bar of tent is distributed with a pin joint seat, the connection pin joint seat, and the Flexible element with the radical such as support bar, make each support bar that there is screen resilience with respect to the downward folding inch of pin joint seat, relatively turnable activity relationship is constituted between every support bar unit and pin joint seat, each Flexible element one end connects the support bar unit, other end connection pin joint seat.Folding the tent inch needs to force in each support bar concentration closing；And deploy tent inch and only need to release to exert a force, will upwards it be deployed with respect to pin joint seat to support bar using the restoring force of elastomer unit, with up to the function of Automatic-expanding tent.The tent top support frame of the structure mainly leans on each elastomer unit resilient support as can be seen here, easily makes support bar produce folding downwards if tent top stress, thus can there are the not enough defect of support strength；Other support bar is acted on by the elastic force of elastomer, is understood and is upturned with respect to pin joint seat is unconfined, is only limited by tent cloth, influenceed inch by wind-force or other external force in tent, tent bracket is easily rocked, and makes tent lack the stability of support.

[3] it is a primary object of the present invention to provide one kind to make after tent expansion, the downward folding of tent top stress inch support bar is prevented, it is ensured that the top support structure of tent frame of tent support intensity.

[4] secondary objective of the invention is that providing one kind makes after tent expansion, and tool preferably positioning support bar upwarps angle, it is ensured that the top support structure of tent frame of tent support steadiness.

[5] to achieve the above object, technical solution of the invention is：
