Abstract

The utility model provides a special key for a gate lock of a front gate of a high-voltage switch cabinet, comprising a lock handle, a lock body and a handle shaft which are hinged in sequence, wherein a lock key is further connected at the lower end of the lock handle; the handle shaft is further sleeved with a handle sleeve; and the handle sleeve can rotate around the handle shaft. The special key provided by the utility model has the beneficial effects that: with the adoption of the technical scheme, the operation time of locking and unlocking the gate lock of the front gate of the high-voltage switch cabinet is greatly shortened; the output force is greatly reduced when an operator operates; sliding friction caused by contacting the operating handle with hands of the operator is effectively avoided; two sets of movement pairs which are rotated by a second pin and a third pin, so that the locking and unlocking of the gate lock of the cabinet body, which is arranged at the right end and is close to a wall, can be effectively solved; and the problem that the hands of the operator are injured can be effectively solved.

Description

A kind of high-tension switch cabinet Qianmen door lock private key

Technical field

The utility model belongs to power distribution high-tension switch cabinet technical field, especially relates to a kind of high-tension switch cabinet Qianmen door lock private key.

Background technology

One type of Qianmen door lock key of switchboard use at present is to adopt the simple structure of whole cast iron moulding to form.This type key is low especially to the locked of Qianmen door lock and release efficient in cabinet assembling and setting and on-the-spot use; Time spent is long especially: 8 door locks are arranged on the general cabinet; Every have door lock 11 to buckle screw thread, can not carry out the continuity operation during operation, and general Rotate 180 degree need be changed hands operation once; The separate unit cabinet realizes that a switch door approximately needs to fall 176 hands, and can't carry out the continuity hitless operation.This type key makes operating personnel can't stand the destructive effect of powerful pressure to hand because the effective arm of force of effect very short (approximately 45mm) thereby the operation power output that needs need be very big through regular meeting; This type key is easy to when operating physical force is big, rupture suddenly owing to adopt cast iron materials, and operator's hand is caused great injury.This type key human oriented design parameter in the process of whole use is low especially.

Summary of the invention

The problem that the utility model will solve is when unblanking, can't carry out the continuity hitless operation thereby a kind of high-tension switch cabinet Qianmen door lock private key is provided, and especially is fit to a kind of high-tension switch cabinet Qianmen door lock private key of power distribution high-tension switch cabinet.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high-tension switch cabinet Qianmen door lock private key is characterized in that: comprise hinged shank of the key, lock body and the Handle axis of order successively,

Said shank of the key lower end also is connected with a locking key.

Further, carry out pin joint together through first pin between said shank of the key and the locking key.

Further, said Handle axis also is with taper knob, and taper knob can thorny arbor rotation.

Further, said Handle axis respectively is provided with the back-up ring of a restriction taper knob axial float in the rear and front end of taper knob.

Further, said shank of the key is having keyway in the end that is connected that links to each other with the lock body, and the end that is connected that links to each other with shank of the key of lock body is stretched in the keyway, and is connected the end with shank of the key and is hinged.

Further, said lock has keyway in the end that is connected that links to each other with Handle axis, and the end that is connected that links to each other with the lock body of Handle axis is stretched in the keyway, and is connected the end with the lock body and is hinged.

Advantage and the good effect that the utlity model has are: because this programme adopts the mode of operation of rotating continuously, the operating time when making the locked and release of high-tension switch cabinet Qianmen door lock shortens greatly, thereby improves operator's efficiency; Adopted the mode that strengthens the operation brachium, the power output the when operator is operated reduces greatly; The form that has adopted taper knob to cooperate with Handle axis has effectively been avoided operating grip and the sliding friction that operator's hand contacts, and is more comfortable when the operator is operated; Adopted two cover kinematic pairs, effectively solved right-hand member and leaned on wall that the locked and release of cabinet door lock is installed with second pin and the 3rd pin rotation; Efficiently solve the injured problem of operating personnel's hand; Its design concept is advantage such as hommization more.
