Description

Technical Field

[0001] The utility model relates to a manual unlocking mechanical device for an electric lock configured for a unit Chinese medicine cabinet, in particular to an unlocking device for manually opening the electric locks of corresponding medicine adding doors and / or inspection doors when the electric locks of several unit Chinese medicine cabinets constituting an intelligent Chinese medicine cabinet system malfunction due to a fault. Background Art

[0002] A Chinese patent document (CN208966156) discloses an unmanned vending machine unlocking device. Upper and lower emergency unlocking devices are located above and below the upper and lower electric locks, respectively. The unlocking device comprises a central lock cylinder mounted on the cabinet door, a lock handle, and a central lock cylinder connected to a transmission. A steel cable is connected to a locking plate at one end and to one end of a lever at the other end. The other end of the lever is movably linked to the unlocking lever of the electric lock. This unlocking device has the following problems: it takes up a lot of space, is complex in structure, and the cable transmission lacks reliability.

[0003] The inventor's <Smart Chinese Medicine Pharmacy Intelligent Automatic Dispensing and Dispensing System for Chinese Herbal Medicine Slices> consists of an intelligent Chinese medicine pharmacy system, a rail trolley system, a dispatching system, a medicine shortage replenishment system, a medicine inspection system and a mobile terminal; the intelligent Chinese medicine pharmacy system is composed of several unit medicine cabinets. According to the different properties of Chinese medicine, each unit medicine cabinet is equipped with a hopper built-in stirring terminal device, a special conveying device for Chinese herbal medicine slices, a metering pushing and flipping device and a metering correction device, etc., so as to realize the intelligence of the entire process of adding, delivering and dispensing medicine. An electric lock is installed on the dosing door and / or maintenance door on each unit medicine cabinet. However, when the electric lock fails due to a malfunction, manual unlocking is required to solve the problem of immediate dosing or maintenance, otherwise it can only be unlocked violently and destructively. Utility Model Content

[0004] The utility model aims to provide a manual unlocking device which can be attached to an electric control lock and has a compact structure and is convenient for opening the electric control lock.

[0005] The manual unlocking device that can be attached to the electric lock is realized as follows: a manual unlocking device that can be attached to the electric lock includes an electric lock with a manual switch, the fixing seat is a bent plate, and is composed of a horizontal plate and a vertical downward plate; the tongue fixing seat and the lock body are respectively arranged on the rear bottom surface and the front bottom surface of the horizontal plate of the fixing seat, and the tongue structure is: the arc-shaped protrusion used to trigger the manual switch of the electric lock is fixedly connected to the cylinder, and together with the front part of the cylinder, it forms a keyhole that matches the key rod and bar teeth of the key; the rear cylinder and the front cylinder of the tongue are respectively mounted between the opening of the tongue fixing seat and the rear opening of the lock body, and form a rotational fit with the tongue fixing seat and the rear of the lock body, and a reset spring is provided on the rear part of the tongue; the above-mentioned lock body is provided with a lock body keyhole that matches the key rod and bar teeth of the key, and the electric lock is mounted on the inner surface of the vertical downward plate of the fixing seat.

[0006] The utility model also has a key, which is composed of a key rod with one end fixedly connected to a handle and the other end fixedly connected to a bar-shaped tooth.

[0007] The arc-shaped convex head is integrally fixed on the cylinder; the tongue fixing seat, the lock body and the electric control lock are respectively fixed on the fixing seat via screws.

[0008] When the key is inserted into the cam keyhole from front to back through the keyhole of the lock body, and the key is twisted clockwise, the bar teeth on the key overcome the torsional force of the return spring to deflect the cam. During the deflection of the cam, the arc-shaped convex head on the cam generates a downward pressing force on the manual switch on the electric lock, thereby enabling the electric lock to be manually unlocked.

[0009] The beneficial effects of the utility model are:

[0010] The lock mouth and mechanical opening device of the electric lock are respectively arranged at the two ends of the electric lock. When the device is powered off or the electric lock fails, it is not operable when manual unlocking operation needs to be performed at the same end. To solve this problem, the usual practice is to open a hole on the side and use a probe to press the mechanical opening device of the electric lock to unlock it; or to open a hole on the front and use a probe to press the mechanical opening device of the electric lock to unlock it. However, both methods have usage limitations: the first method is not feasible when the side is blocked; because the probe has to penetrate to a greater depth in the second method, coupled with the obstruction of the electric lock, manual operation is more difficult. The function of this unlocking device is to effectively solve the problem of manual unlocking of the electric lock from the front in the event of a power outage or electric lock failure.

[0011] The structure is compact, suitable for installation in the narrow space of the unit medicine cabinet, and is easy to unlock. BRIEF DESCRIPTION OF THE DRAWINGS
