Abstract
The utility model overcomes a kind of the not enough there is provided mine explosion-proof switch two is anti-lock of prior art presence, and this two anti-lock has the characteristics of saving space, prevent destructive procedure, long service life；In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of mine explosion-proof switch two is anti-lock, including locking bar, lock core, lock and spring, the lock core is movably arranged in lock, the blocking lever passes through lock core, the spring is located inside lock core and is sleeved on blocking lever, for the reset of blocking lever, the L-type groove of two connections, locking and unblock for blocking lever are provided with the lock core；The utility model can be widely applied to mining two anti-lock fields.
Description
Technical field
A kind of mine explosion-proof switch two of the utility model is anti-lock, belongs to mining two anti-lock technical fields.
Background technology
Mine switch lock with two precautions can effectively " prevent without authorization power transmission, prevent operation of uncapping without authorization ", and this device is applied to ore deposit
With magnetic starter, mining automatic feed switch, mining hand starter, Electric drill for mine comprehensive device of transformer, mining illumination
The mining equipment such as signal synthesis protection device and leak detection protection device, it can also be used to the locking in other places.With preventing without authorization
Power transmission, prevents uncap without authorization controlling electric device element, adjustment setting value, prevents from stealing three kinds of functions of electrical equipment, can be from equipment
Nothing " two prevent " function hidden danger that Mine Switch is present is eliminated, prevents watt of " two arrogate to oneself " (power transmission, operation of uncapping without authorization without authorization) initiation
This dust explosion accident.
Utility model content
The utility model overcomes a kind of the not enough there is provided mine explosion-proof switch two is anti-lock of prior art presence, and this two
It is anti-lock that there is the characteristics of saving space, prevent destructive procedure, long service life.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is：A kind of mine explosion-proof switch two is prevented
Lock, including blocking lever, lock core, lock and spring, the lock core are movably arranged in lock, and the blocking lever passes through lock core, institute
Spring is stated inside lock core and is sleeved on blocking lever, for the reset of blocking lever, the L of two connections is provided with the lock core
Type groove, locking and unblock for blocking lever.
Described blocking lever one end end is actively plugged in guard housing.
The utility model has an advantageous effect in that compared with prior art：The utility model increases spring in lock,
Enable its automatic spring when specific purpose tool is opened, without carrying out rotating open-close lock with instruments such as hand or hand vice, in addition,
The utility model is provided with the L-type groove of two connections, locking and unblock for blocking lever on lock core.
Brief description of the drawings
The utility model is described further below in conjunction with the accompanying drawings.

The cross-sectional view that Fig. 6 is A-A in Fig. 4.
In figure：1 it is blocking lever, 2 be spring, 3 be lock, 4 is lock core.
Embodiment
As shown in Fig. 1~Fig. 6, a kind of mine explosion-proof switch two of the utility model is anti-lock, including blocking lever 1, spring 2, lock
Seat 3 and lock core 4, the lock core are movably arranged in lock, and the blocking lever passes through lock core, and the spring is located inside lock core
And be sleeved on blocking lever, for the reset of blocking lever, the L-type groove of two connections is provided with the lock core, for blocking lever
Locking and unblock.
One end end of blocking lever 1 is actively plugged in guard housing.
Use process of the present utility model：
First, uncap process（Initial position is locking closure power transmission position）.
1st, power transmission position rotates to power failure position, is promoted with specific purpose tool front -- and 90 ° of dextrorotation, is now anti-anti- send of uncapping
Electric position；
2nd, being promoted with specific purpose tool front -- 90 ° of dextrorotation, is now anti-power transmission position of uncapping.
3rd, handle of uncapping is rotated to uncap.
2nd, transmission process（Initial position is power failure position of uncapping）.
1st, Jiang Gai is shut, and is promoted with specific purpose tool front -- and left-handed 90 °, be now anti-anti- power transmission position of uncapping；
2nd, promoted with specific purpose tool front -- left-handed 90 °, be now the anti-uncapped position of power transmission.
3rd, rotate handle and carry out power transmission.
The characteristics of the utility model：
1st, increase spring in lock, enable its automatic spring when specific purpose tool is opened, without with hand or hand
The instruments such as pincers carry out rotating open-close lock；
2nd, the operation of switch side is changed into front-operated, reduces the operating space of side；
3rd, sheath and guard housing are added on exposed blocking lever, it can only be opened with specific purpose tool " two is anti-lock ",
Prevent destructive rotation.
Embodiment of the present utility model is explained in detail above in conjunction with accompanying drawing, but the utility model is not limited to
Embodiment is stated, in the knowledge that those of ordinary skill in the art possess, the utility model objective can also not departed from
On the premise of various changes can be made.
