Problems solved by technology

But this unlocking mechanism still has its own disadvantages: 1. The unlocking torque of the mechanism (the product of the active force applied by the human body and the radius of the handwheel of the unlocking mechanism) is small, and the finger force is small; 2. The handwheel is inconvenient to operate (large shape , need the thumb, index finger, and middle finger to act at the same time); 3. Due to the large shape and volume of the unlocking mechanism, the entire computer key has a large shape

Embodiment Construction

[0010] see figure 2 , an unlocking mechanism used in computer keys for anti-misoperation locking in power systems, which includes a push button 10 (only the shaft of the push button can be seen in this figure), a rack 17, a gear-type electrode shaft 11, an electromagnet 20, Mechanism state detection unit, the rack 17 meshes with the geared electrode shaft 11 to realize torque transmission, the push torsion 10 is located at the bottom of the rack 17 and rigidly connected with it, of course, the two can also be an integrated structure; the mechanism state detection unit includes Detection wheel 16, detection plate and light control hole.

[0011] see figure 2 , a computer key using the above-mentioned unlocking mechanism, also includes a casing (not shown in the figure), a coding head 12, a control unit (not shown in the figure); the casing is composed of an upper cover assembly and a base assembly 13; the The control unit and the unlocking mechanism are located in the housi...

Abstract

The invention is especially related to guiding against error operation of blocking devices and assemblies for microcomputer in order to prevent error operation to plant and station for power distribution and delivery. The push button type unlock mechanism includes electromagnet, unit for detecting state of mechanism, and moment transmission mechanism of gear wheel. The mechanism includes rack and gear wheel typed electrode axis, which are engaged each other to implement moment transmission. Being located at bottom of the rack, the push button is connected to the bottom rigidly. Being installed inside guide groove of case, the rack can be moved up and down. Force of acting on the push button is transferred to the mechanism directly. Under precondition of not increasing transmission rate, using mode of applying force by thumb and through computer key held by hand increases enforceable maximum moment by human body so as to increase maximum unlocking moment for mechanism greatly.

Description

technical field [0001] The invention relates to the technical field of anti-misoperation locking of power systems, in particular to a microcomputer anti-misoperation locking device and its components used in power plants or distribution power stations such as power stations to prevent misoperations. Background technique [0002] At present, in the existing microcomputer anti-misoperation locking device, a computer key with a code recognition function and a mechanical lockset are generally used to cooperate to complete the anti-misoperation locking function. The computer key has a coding head located on the casing and an unlocking mechanism contained in the casing as the most important actuator of the computer key. Currently commonly used unlocking mechanisms include push-button and rotary wheel types, and the unlocking mechanism generally includes a torque transmission mechanism, a mechanism state detection unit, and an electromagnet; figure 1 Shown is a schematic diagram o...
