| 摘要 |
<p>This invention relates to a pushrod-type tent frame including a base, a frame linkage and a controlling mechanism. The frame linkage has two support sets 5 arranged in parallel, each having a supporting pole, an upper supporting pole and a lower supporting pole pivotally connected in sequence. The supporting pole has an outer end pivotally connected to a front edge of the base, and the lower supporting pole has an outer end pivotally connected to a rear edge of the base. The controlling mechanism has two rod-pushing mechanisms pivotally connected 10 to the two support sets, respectively. Each of the rod-pushing mechanisms has a driving device for driving a telescopic rod assembly to change its reach and thereby prop up or release the frame linkage, so as to expand the tent frame or allow the tent frame to be retracted.</p> |
