The logical head of a kind of tent and cross bar limiting locking mechanism
Technical field
The present invention relates to tent frame field, specifically the logical head of a kind of tent and cross bar limiting locking mechanism.
Background technique
Tent is a kind of portable equipment, and tent of a great variety is mainly used in field work, tourism, the anti-dangerous disaster relief, military etc.Existing tent is mainly made up of paulin frame and paulin body, and the erection process of tent is to set up the last tarpaulin of tarpaulin again and support together with paulin frame after first paulin frame being set up to a part.The paulin frame of existing large-scale tent sets up that step is many, and erection process is that paulin hack lever part is pegged graft piecemeal, operates loaded down with trivial detailsly, sets up inconvenience, and the speed of setting up is slow; And the parts of existing tent frame are more, volume is large, installation, maintenance difficulty.
Summary of the invention
The object of the invention is to overcome existing tent rod member and connects the problem existing, and the logical head of a kind of tent and cross bar limiting locking mechanism are provided, and is specifically realized by following technological scheme.
The logical head of a kind of tent and cross bar limiting locking mechanism, this structure comprises cross bar sleeve pipe, clamping block, connection block and a logical plate, connection block is fixedly installed on a logical plate, described connection block is plugged in described cross bar sleeve pipe, described connection block outside is provided with ring-type draw-in groove, described clamping block is arranged on rotationally on a logical plate by torsion spring and is corresponding with described ring-type draw-in groove, the end of described cross bar sleeve pipe is provided with clamping block jack, described clamping block end is plugged in described clamping block jack, described clamping block middle part is provided with bayonet socket, described cross bar sleeve pipe is provided with the longitudinal screens muscle corresponding with described bayonet socket.
The logical head of described tent further designs and is with cross bar limiting locking mechanism, described clamping block is provided with twist lock hole, on a described logical plate, be fixedly installed twist lock cover, described twist lock is provided with twist lock screw in hole, described twist lock screw is connected with described twist lock thread die cutting, and described torsion spring set is located on twist lock screw and connects clamping block and twist lock cover.
The present invention is rational in infrastructure, esy to use, safe and reliable.
