Embodiment Construction

[0031] The specific embodiments of the safety locking procedure device of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] In order to facilitate the understanding of the present invention, some directional terms are used in this specification. It should be noted that the directional terms mentioned in this specification, such as "up", "down", "left", "right", etc., refer to the directions of the drawings, and the directional terms used are used to illustrate and understanding of the present invention, but not to limit the protection scope of the present invention.

[0033] see attached Figures 1 to 4 , the housing 1 of the safety locking procedure device is a cuboid structure with a lock cover 2 above it. The housing 1 can adopt a flip-cover or a closed-cover structure. It can be fixed by screws or by direct welding. A carrying handle is arranged on the outer side of the casing 1 to facilitate the handling of th...

Abstract

The invention relates to the technical field of electrical safety production and discloses a safety interlocking program device. A program board is arranged in a housing through a sliding mechanism, an incoming line lock and at least two outgoing line locks are mounted to a lock cover of the housing, a playground-shaped first elongated hole is formed in the program board and in the position corresponding to the incoming line lock, a playground-shaped second elongated hole is formed in the program board and in the position corresponding to each outgoing line lock, the path of motion of each outgoing line lock from an unlocked state to a locked state is a 90-degree arc, an arc hole is formed in the program board and in the position corresponding to the 90-degree arc, and the arc hole is communicated with the second elongated holes. After the device is assembled, a bolt of the incoming line lock is inserted into the first elongated hole, and a bolt of each outgoing line lock is inserted into the respective second elongated hole or the arc hole. According to the invention, by operating the incoming line lock and the outgoing line locks, applicationprogram of a key conforms to the requirements for electrical safety working regulations.

Description

technical field [0001] The invention relates to the technical field of electrical safety production, in particular to a safety locking procedure device. Background technique [0002] Power plants, substations, substations, isolating switches, and grounding switches have strict operating procedures for the switch-off operation. If this procedure is only followed by humans, mistakes will inevitably occur, resulting in misoperation, short circuit, equipment damage or electric shock. Personal accident. Therefore, the blocking measures for preventing misoperation of power switches are mandatory requirements of national and international electrical product standards. The current anti-misoperation measures include electrical locking, mechanical linkage locking, and lock cylinder can toggle the program lock. Realization; the lock cylinder can be dialed and the program lock is also prone to misoperation due to the displacement of the lock cylinder sometimes. SUMMARY OF THE INVENTI...
