Abstract

The utility model discloses a door lock for auto vending machine, which consists of an outer slide slot positioned on the opening side of the door, an inner slide plate positioned out of the outer slide slot and a lock hook positioned on the auto vending machine; the inner slide plate and the outer slide slot are connected by an axis; lateral plates on both sides of the inner slide plate are provided with vertical bar-shaped holes; the inner slide plate can slide up and down within the length scope limited by the bar shape; the inner slide plate releases the lock hook after sliding upwards and is rising, and closes the lock hood after sliding downwards and resetting; a position limiting mechanism is positioned between the inner slide plate and the outer slide groove, which stops the inner slide plate at a position after sliding upwards and elevation when the door is opened, releases the inner slide plate when the door is closed, and makes the inner slider plate self sliding downwards and reset. The inner slide plate is unnecessary to be elevated upon door locking, which provides great convenience.

Description

The door of vendor lock

Technical field

The utility model relates to a kind of door lock, relates in particular to a kind of door of vendor lock.

Background technology

Automatic vending machine door lock of the prior art is mainly formed by being located at an external chute of body open side, placing the inner slider in the external chute and being located at the latch hook that cooperates with above-mentioned inner slider on the automatic vending box body; Inner slider can slide up and down in the certain limit in external chute.When lock-out state, the inner slider bottom is stuck in the latch hook on the casing, when opening the door, by the key drive transmission device will be on the inner slider sliding the lifting, thereby make it to break away from latch hook, realize that the door body opens.Its defective is: after the door body was opened, inner slider glided because of action of gravity, needed by external force inner slider to be promoted once more when locking a door, and glide after making it to reach a certain height reset of card and latch hook are realized the locking of door body again.Increased operation easier, wasted time and energy.

Summary of the invention

Artificially external force just can be with the automatic vending machine door lock of door locked with the inner slider lifting when the purpose of this utility model just was a kind of locking a door is provided.

The utility model door of vendor lock, it is mainly by being located at an external chute of body open side, placing the inner slider in the external chute, and is located at the latch hook that matches with inner slider on the automatic vending box body and forms; Inner slider is connected by axle with external chute, and the both sides side plate of inner slider is provided with the vertical strip hole that matches with described axle, slides up and down in the length range that inner slider can be limited in described strip hole in external chute; The sliding back that promotes discharges latch hook on the inner slider, engaging latch hook after its downslide resets; Be characterised in that: be provided with the position that makes after inner slider stops at sliding the lifting between inner slider and the external chute when the door body is opened, discharge inner slider when closing body, the position that inner slider is glided voluntarily reset limits mechanism.The utility model is because the position limits the effect of mechanism, and the position after the door body unblanks to make inner slider stop at lifting when promptly opening is closed once more when a body is promptly locked a door and discharged inner slider, makes its downslide engaging latch hook that resets realize the locking of door body; Promote inner slider when need not to lock a door, easy to operate.

Above-mentioned position limits mechanism and can realize like this, is provided with the inner slider hook between the side plate of inner slider both sides, and the base portion of inner slider hook is fixed on the described axle; Above-mentioned inner slider hook is made up of L-shaped hook section and the base portion of a cardinal principle, and its base portion is provided with a hole of passing for axle, and the ledge of its hook section is towards inner slider one side; Between inner slider hook and external chute, be provided with spring; Slide the lower surface that the ledge that promotes back inner slider hook hook section leans out inner slider when opening the door on the inner slider, with the position after the inner slider holding is on promoting, described at closing time latch hook compresses the hook section ledge of inner slider hook in external chute, make inner slider lose holding and glide voluntarily and reset.It is easy to be easy to realize.

Above-mentioned spring can realize like this that the spring main body is on the axle between the above-mentioned inner slider biside plate, and its two ends are against respectively on above-mentioned outer slide plate inwall and the inner slider hook.
