Abstract

The utility model discloses a lock body of a vertically-mounted anti-misoperation lock; an electromagnetic lock slot in which an electromagnetic lock body can be placed, and a sensor slot in which a sensor can be placed are machined on the lateral surface of a lock base, vertical holes used for the placement of a lock pin and a lock pin spring are machined from the top surface to the bottom surface of the lock base, an annular concave groove is machined on the lateral wall of the lower part of the lock pin, the lock pin spring nested on the lock pin is clamped between the axial joint of the lock pin and the inner wall of the lock base, the top end of the lock pin is threaded through the vertical holes and the lock pin handle to be buckled on the top surface of the lock pin handle; when the lock is locked, the lock tongue of the electromagnetic lock is extended out of the electromagnetic lock body to run through the electromagnetic lock slot and be clamped in the concave groove. The lock body coordinates with the electromagnetic lock and the sensor mounted on the lock body to detect the equipment state and locking and unlocking states, so the lock body of the vertically-mounted anti-misoperation lock has the advantages of convenient use, firm locking and accurate detection.

Description

A kind of anti-misoperation locking lock body of vertical installation

Technical field

The utility model relates to a kind of anti-misoperation locking lock body that is used for preventing faulty operation of electric power system, especially can electromagnetic lock be installed thereon, itself can adopt the lock body that vertically is installed on the substation equipment.

Background technology

At present microcomputer anti-error operating system has been widely used in the transformer station, power plant of power system.Lockset in the anti-misoperation system mostly is mechanical lock greatly, can be by equipment such as electric or mechanical system locking switch, disconnecting link (cutter), pile and net doors.But mechanical lock can only simply lock, virtual condition that can not checkout equipment, switching lock state that can not detection itself.Because this type of deficiency uses the microcomputer anti-error operating system of this lockset just to have a serious deficiency, that is: when carrying out on-the-spot switch operation, device physical status is not known by system, does not know the open and-shut mode of lockset yet.All states can only rely on artificial judgement, and the very big possibility of makeing mistakes is arranged, as: just only release and do not have operation carry out next step operation of current device, this situation is become " do-nothing operation ", and consequence is device damage, personal injury often; Current device operation back is non-latching, and this situation is become " empty locking ", causes equipment to be in no blocking, in case by malfunction, consequence is also very serious.Use can not checkout equipment virtual condition, the anti-misoperation system of the lockset of switching lock state that can not detection itself can only be finished " five is anti-" function of discounting.

Summary of the invention

Can not the checkout equipment state and open and close the problem of lock state for the lockset that solves present anti-misoperation system, the utility model provides a kind of anti-misoperation locking lock body of vertical installation, and its technical scheme of taking is:

This lock body comprises lock, lock pin, lock pin spring and lock pin handgrip, the side of lock has the electromagnetism locked groove that can place the electromagnetic lock lock body and can place the sensing tank of sensor, lock has the vertical core of placing lock pin and lock pin spring from the end face to the bottom surface, vertical core near the aperture of upper port part less than other parts and be a bit larger tham the diameter of axle of lock pin, the diameter of axle on lock pin top is less than the diameter of axle of its underpart, have annular recess on the sidewall of lock pin lower part, being enclosed within lock pin spring on the lock pin is connected between the inwall of be coupling place and lock of lock pin, the top of lock pin is passed vertical core and lock pin handgrip and is snapped onto the end face of lock pin handgrip, the lock end face be shaped as the circular ring structure that radial position has projection, the bottom shape of lock pin handgrip is the circular ring structure that radial position has prominent groove, when the lockset locking, the electromagnetic lock dead bolt stretches out from the electromagnetic lock lock body and passes the electromagnetism locked groove and is stuck in the groove, this moment, lock was entrenched in the lock pin handgrip, when lockset is unblanked, the electromagnetic lock dead bolt is withdrawn in groove, handgrip is raised and rotates to an angle, the annulus bottom surface that makes the projection on the lock end face withstand the lock pin handgrip.

At blocking, to mention the lock pin handgrip and rotate to an angle, handgrip can be lived by the support structure on the lock, and lock pin also can withdraw and maintain, and lock body is finished and is unblanked; At unlocking condition, to mention the lock pin handgrip and rotate to an angle, handgrip can reset under the effect of lock pin spring, and lock pin also stretches out and maintains, and lock body is finished locking.

This lock body cooperates with electromagnetic lock and the sensor installed thereon, can the checkout equipment state.Lock body adopts fixed form to be installed on the equipment, such as lock body is fixed on the substation equipment, realizes the locking to substation equipment.That this lock body has is easy to use, locking firmly, detect characteristic of accurate.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail:

As shown in Figure 1, the side of lock 3 has the electromagnetism locked groove 8 that can place electromagnetic lock lock body 13 and the sensing tank 9 that can place sensor 10, by electromagnetic lock fixed screw holes 4 magnetic padlock lock body 13 is fixed in the electromagnetism locked groove 8,, can be fixed on lock 3 on the equipment in the sensor 10 sensing tanks 9 by sensor fixed screw holes 6 by lock body fixing hole 5.

As shown in Figure 3 and Figure 4, lock 3 has vertical core 15 from the end face to the bottom surface, vertical core 15 near the apertures of upper port part less than other parts and be a bit larger tham the diameter of axle of lock pin 7, the diameter of axle on lock pin 7 tops is less than the diameter of axle of its underpart, is enclosed within lock pin spring 14 on the lock pin 7 and is connected between the inwall of be coupling place and lock 3 of lock pin 7.Have annular recess 16 on the sidewall of lock pin 7 lower parts, the top of lock pin 7 is passed vertical core 15 and lock pin handgrip 2 and is snapped onto the end face of lock pin handgrip 2 by clasp, and lock pin handgrip 2 can be with respect to lock pin 7 independent rotation.Lock 3 end faces be shaped as the circular ring structure that radial position has projection, the bottom shape of lock pin handgrip 2 is the circular ring structure that radial position has prominent groove.When lock body was in blocking, electromagnetic lock dead bolt 12 stretched out from electromagnetic lock dead bolt lid 11, is stuck in the annular groove 16 of lock pin 7, stopped the vertical axial motion of lock pin 7 in lock 3.This moment, lock pin 7 can not be raised, and lock 3 is entrenched in the lock pin handgrip 2, and under the effect of lock pin spring 14, lock pin 7 can remain on the state of stretching out.

As shown in Figure 2, when electromagnetic lock was unblanked, electromagnetic lock dead bolt 12 was withdrawn from the annular groove 16 of lock pin 7, and lock pin 7 can be done the vertical axial motion in lock 3.Mention lock pin handgrip 2 this moment, and lock pin 7 is raised simultaneously, and lock body is in unlocking condition.At this moment, lock pin handgrip 7 is rotated to an angle, the projection on lock 3 end faces is withstood the annulus bottom surface of lock pin handgrip 2, and lock pin handgrip 2 is lived by the support structure on the lock 3, and lock pin 7 can remain on retracted mode.
