Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, reasonable in design, easy to operate hand barrow seat locking and relief structure.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of hand barrow seat locking and relief structure, comprise seat segmentation seat and supporting base of seat, it is characterized in that: supporting base of seat is provided with key hole, key hole is provided with button, is fixed with button permanent seat in supporting base of seat, and button is located in button permanent seat, button cover has by key spring, and button can move in button spring travel; Seat segmentation seat bottom is provided with bayonet lock fixed orifice, in bayonet lock fixed orifice, be provided with hold-open catch, porose in hold-open catch, hold-open catch by bayonet lock fixedly iron prop up and be installed in seat segmentation seat, bayonet lock fixedly iron props up the hole through hold-open catch, and the aperture in this hole is greater than the bayonet lock diameter that fixedly iron props up; Between hold-open catch and seat segmentation seat, be provided with bayonet lock spring, hold-open catch is withstood in bayonet lock spring one end, and the other end withstands on seat segmentation seat, and hold-open catch can move within the scope of bayonet lock spring travel; On button permanent seat, there is the bayonet lock knock hole with bayonet lock fixed orifice with formed objects and shape; The top of supporting base of seat is stretched in the bottom of seat segmentation seat, alignment mutually between button, bayonet lock knock hole, bayonet lock fixed orifice, hold-open catch and bayonet lock spring; Button inner end is provided with the button grab that can fasten supporting base of seat or seat segmentation seat.
Further, in described seat segmentation seat, be provided with hook in the seat segmentation seat matching with button grab, under seat lock-out state, button grab leaves hook in seat segmentation seat and is stuck in inside supporting base of seat, and hold-open catch snaps in the bayonet lock knock hole of button permanent seat; Under seat released state, button grab leaves supporting base of seat and fastens hook in seat segmentation seat, and hold-open catch leaves bayonet lock knock hole and enters completely in bayonet lock fixed orifice and by bayonet lock spring-compressed, and button is by button spring-compressed simultaneously.
Further, described button permanent seat is screwed in supporting base of seat, and seat segmentation seat inserts after supporting base of seat, and button permanent seat is inserted in the inside, seat segmentation seat bottom.
Under normal circumstances, seat is in the lock state, and now, button is in down state not, and hold-open catch ejects, and enters in the bayonet lock knock hole of button permanent seat, and seat segmentation seat is locked; While unlocking, push button, button grab leaves supporting base of seat and then fastens hook in seat segmentation seat, and hold-open catch leaves bayonet lock knock hole and enters completely in bayonet lock fixed orifice and by bayonet lock spring-compressed, button, by button spring-compressed, now can take out seat segmentation seat simultaneously.After seat takes out, in button grab and seat segmentation seat, hook departs from, and button is owing to getting back to again original state under the effect of button spring force.
The utlity model has following advantage: simple in structure, cause cost lower, during operation, operator does not need seat both sides to be operated simultaneously, can complete on one side and operate again another side after operation, operate humanizedly, meanwhile, also lowered the operation easier of taking out seat.
