Embodiment in new, the every other reality that those of ordinary skill in the art are obtained under the premise of creative work is not made
Example is applied, belongs to the scope of the utility model protection.
Referring to a kind of folding stand locking device up and down shown in Fig. 1 to Fig. 4, the locking device is arranged on turnover up and down
Front frame 1 and Rear frame 12 between, including be fixed on the both sides of front frame 1 first locking jaw 9, be fixed on 12 liang of Rear frame
Second locking jaw 10 of side, the first locking jaw 9 and second are provided with latch assembly, the lock between locking jaw 10
Tight component includes the rotational pin 7 being arranged in the second locking jaw 10, pin rod 4 is connected with the rotational pin 7, in the pin rod 4
On be connected with compressing structure, when pin rod 4 is pulled to the first locking jaw 9, the compressing structure compresses the first locking jaw 9.
Process is as follows when in use for the utility model, when needs beat the front frame 1 folded up and down and Rear frame 12
When opening and lock, first front frame 1 and Rear frame 12 are deployed, pin rod 4 is then turned to second from the first locking jaw 9
Jaw 10 is locked, then the first locking jaw 9 can be locked by compressing structure.When needing front frame 1 and Rear frame 12
When unlocking, operation compressing structure makes it no longer compress the first locking jaw 9, then pitches pin rod 4 from the second locking
Produced in first 10.
Compressing structure of the present utility model can take various forms, and such as coordinated by nut 8 and pin rod 4, make it
Locking jaw is compressed, but this structure operation is inconvenient, so in the utility model, the compressing structure includes be hinged connect
The spanner 2 being connected on pin rod 4, in addition to the pad 5 and spring being connected on pin rod 4, the diameter of the pad 5 are more than the first lock
The prong of tight jaw 9, the diameter of the spring are less than the prong of the first locking jaw 9, and the pad 5 is slidably connected to pin
On bar 4, the spring is arranged between the pad 5 of pin rod 4 and rotational pin 7；The initiating terminal of the pin rod 4 is provided with an articulated joint
6, the spanner 2 is arranged in the articulated joint 6 by the way that rivet 3 is be hinged, and the spanner 2 includes eccentric wheel and throw rod 11, institute
