The course of work of access door, locking bar and multiple switch etc. is:

1. access door is opened

Anti-theft panel moves ahead, and the push rod on right side is firstly inserted into below roller group, and locking bar is synchronous to be risen, and lower end is from protrusion Abjection in lockhole, the locking bar status switch of touching top when locking bar rises to highest order, at this point, the idler wheel on the push rod in left side pushes away Rotation block is pushed up, the shaft of rotation block drives the upward rotation of rotation bar, due to rotation bar lower end and access door middle side edge place on the upper side Hinge dress, so access door upper end is to door-plate interior direction rotation, and access door lower end is to door-plate lateral direction rotation, in access door When just having started rotation, protrusion leaves the access door status switch of top, which indicates that access door to be ready opening, under access door Two idler wheels 99 of end two sides installation scroll up along track interior, until the idler wheel on right side touches the picking door state of lower section Switch, the switch indicate access door rotation to the top, and access door fully opens.

2. access door is closed

Anti-theft panel retreats, and for two push rods respectively away from rotation bar and locking bar, the push rod in left side is shorter, so first leaving rotation Block, access door rotation reset, and then the push rod on right side and roller group disengage, and locking bar is under the action of tension spring gradually along under lock road Drop, the idler wheel of picking plate lower end is moved downward along track, and gradually when returning to closed position under the effect of gravity, locking bar is just It falls into the lockhole of protrusion, access door is closed and lockked.

Two locking bar status switches are made to generate state change, the idler wheel on the right side of access door lower end during the decline of locking bar The access door status switch of protrusion touching top when leaving lower section access door status switch and access door closing makes two Access door status switch generates state change.

In the utility model, to the mounting structure of the lift itself of vending machine, weighing structure, guiding slide construction and Balanced structure is improved, and solves and problems exist in the prior art, and the access door of vending machine can be set Any one position of door body and access door and anti-theft panel link, and facilitate the I& M of producer, also facilitate people's It uses.
