In the figure: the novel handrail comprises a handrail 1, a baffle plate 2, a chassis 3, a main board 4, a bottom wheel 5, a universal wheel 6, a lock head 7, a bolt hole 8, a push-pull rod 9 and a spring 10.
Detailed Description
The invention is further described below with reference to the accompanying drawings:
referring to fig. 1-5, an adjustable tilt angle unfolding trolley comprises a locking device, a main board 4, a bottom frame 3 and a baffle 2; one end of the main board 4 is hinged with one end of the underframe 3, and the main board 4 can rotate around the underframe 3; the other end of the main board 4 is provided with a locking device, the other end of the underframe 3 is provided with a baffle plate 2, and the locking device can be clamped on the baffle plate 2;
the locking device comprises a lock 7 and a push-pull rod 9, lock grooves matched with the lock 7 in size are formed in two sides of the end face of the main board 4 provided with the locking device, and the two locks 7 are respectively arranged in the lock grooves; the push-pull rod 9 is fixedly connected to the lock head 7 and can pull the lock head 7 to move in the lock head groove.
