Title:
TELESCOPIC SUPPORT MECHANISM
Document Type and Number:
WIPO Patent Application WO/2022/217743
Kind Code:
A1
Abstract:
Disclosed is a telescopic support mechanism, comprising: a support member, a sliding passage being provided on the support member; a sliding member, the tail end of the sliding member being inserted into the sliding passage, and the head end of the sliding member being exposed outside the sliding passage; a screw hole formed in the sliding member; a helical core located in the sliding passage, the head end of the helical core being inserted into the screw hole and helically fitted with the screw hole, the tail end of the helical core being connected to the support member, the helical core being able to circumferentially rotate along its own axis, and the helical core remaining fixed with respect to the support member along the length direction of the support member; a plurality of grooves arranged along the circumferential direction of the helical core; and a locking member that is movable with respect to the support member and is inserted into or exits from the slots. When the locking member exits from the slots, the sliding member is slidable with respect to the support member; and when the locking member is inserted into the slots, the locking member forces the helical core to remain fixed with respect to the support member, such that the support member remains fixed with respect to the sliding member. The unlocking and the pulling of the sliding member for adjustment can be completed merely by pushing the locking member to exit from the slots. The present invention is convenient and quick.
