Abstract

The utility model discloses a double safe compaction lock which effectively improves the running safety of trains. A lock core is arranged inside the body of the double safe compaction lock; the connecting piece of the lock core is arranged in a hole at the tail part of the lock core; and a screw fixing a lock bolt is arranged in the hole at the tail part of the lock core. The double safe compaction lock is characterized in that the dust-proof cover ring of an outer circle, the dust-proof cover ring of an inner circle and the end surface of the lock core are arranged in the end surface hole of the lock body in sequence; the dust-proof cover ring of the outer circle is fixed with the lock body; a slot is arranged on the outer circumference of the end part of the lock core; and a spring penetrates the end part of the lock core and is arranged in the slot. The double safe compaction lock is additionally provided with the safe dust-roof covers which not only play the roles of preventing dust, but also can effectively prevent the lock core from automatically rotating due to shaking, thus further improving the integral safety.

Description

Dual safety compresses lock

Technical field

The utility model relates to railroad train and uses the lock field, more particularly, relates to a kind of railroad train and compresses lock with dual safety.

Background technology

On the railway to the requirements of type selecting strictness of lockset, because safety factor is had relatively high expectations.Along with the continuous lifting of modern railways train speed, a series of attached component product requirement on the train is also improved accordingly.Guaranteeing to improve travel speed under the prerequisite that train safe travels, under the imagination, in the train driving process, locking is failed to realize because of lockset and causes door or cabinet to be opened that consequence will be extremely serious in its a part.

The utility model content

Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art, provides a kind of dual safety of driving safety of effective raising train to compress lock.

The dual safety of the utility model compresses lock, be achieved by following technical proposals, lock core is set in the lock body, the lock core afterbody is provided with the lock core connector in the hole, lock core connector afterbody is provided with the fixedly screw of dead bolt in the hole, it is characterized in that, set gradually the dustproof bezel ring, in outer ring in the described lock body end-face hole, dustproof bezel ring, of inner ring and lock core end face, dustproof bezel ring, in outer ring and lock body are fixed, slot at lock core end outer circumference surface, spring passes the lock core end and is positioned in the groove, and described lock core afterbody hole inner peripheral surface is provided with 90 degree skewed slots, and bearing pin passes lock core connector end and is arranged in the 90 degree skewed slots.

The utility model installs safe dust cap additional on the basis of original lock, this structure not only can play dustproof effect, and can effectively prevent to rotate voluntarily because of the lock core that vibrations cause, and has further improved whole safety.

Description of drawings

Fig. 1 is a structure sectional view of the present utility model;

Fig. 2 is the utility model sectional block diagram.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described further.

As depicted in figs. 1 and 2, lock core 2 is set in the lock body 1, the lock core afterbody is provided with lock core connector 3 in the hole, the fixedly screw 4 of dead bolt is set in the lock core connector afterbody hole, set gradually the dustproof bezel ring, 5 in outer ring, the dustproof bezel ring, 6 of inner ring and lock core end face in the described lock body end-face hole, dustproof bezel ring, in outer ring and lock body are fixed, and the pass and the lock core shape of the dustproof bezel ring, of inner ring are coincide; At lock core end outer circumference surface fluting, spring 7 passes the lock core end and is positioned in the groove; Described lock core afterbody hole inner peripheral surface is provided with 90 degree skewed slots, and bearing pin 8 passes lock core connector end and is arranged in the 90 degree skewed slots.

The utility model is by adding the riveting dust cap to the lock body nose end.Dust cap is made up of the dustproof bezel ring, in outer ring and the dustproof bezel ring, two parts of inner ring, and outer ring dust cap loop section and lock body compress; Inner ring dust cap loop section cooperates with dustproof bezel ring, in outer ring and lock core, and such structure can prevent effectively that lock core is loosening because of the accident that vibrations occur, thereby avoids the generation of contingency.Lock core can't arbitrarily rotate in the pass (can make rational lock shape according to requirement of client) of the dustproof bezel ring, of inner ring, and having only can rotational lock core when using key operated or locking.

Because realize unlatching and locking with key, the dustproof bezel ring, of inner ring should press down in the axial direction, resilience freely, here need be at lock core end outer circumference surface fluting to place spring, and just right power of up and down needs of the dustproof bezel ring, of inner ring, this just need test accordingly to spring, tests qualified spring and should satisfy above-mentioned requirements.

Illustrate that in conjunction with Fig. 1 the utility model is when the locking, lock core 2 revolves to turn 90 degrees by lock body 1, lock core 2 and axle sleeve 9 to be finished jointly, the drive dead bolt revolves and turn 90 degrees, when lock core turn 90 degrees again, because the position-limiting action of axle sleeve and lock body, bearing pin 8 is moved along 90 degree skewed slots of lock core disc, thereby drive the axially-movable of lock core connector, and then realized the axial retraction of dead bolt, dead bolt axial retraction 6mm, realize the substrate hold-down function of dead bolt, thereby reach shockproof purpose doorframe.

Embodiment recited above is described the utility model preferred implementation; be not that design of the present utility model and scope are limited; under the prerequisite that does not break away from the utility model design philosophy; common engineers and technicians make the technical solution of the utility model in this area various distortion and improvement all should belong to protection domain of the present utility model.

Claims

1. a dual safety compresses lock, lock core is set in the lock body, the lock core afterbody is provided with the lock core connector in the hole, lock core connector afterbody is provided with the fixedly screw of dead bolt in the hole, it is characterized in that set gradually the dustproof bezel ring, in outer ring, the dustproof bezel ring, of inner ring and lock core end face in the described lock body end-face hole, dustproof bezel ring, in outer ring and lock body are fixed, at lock core end outer circumference surface fluting, spring passes the lock core end and is positioned in the groove; Described lock core afterbody hole inner peripheral surface is provided with 90 degree skewed slots, and bearing pin passes lock core connector end and is arranged in the 90 degree skewed slots.
