Description

A kind of lorry car door theftproof lock

Technical field

The utility model relates to a kind of lorry car door theftproof lock, belongs to lock technology field, is particularly useful for the antitheft of high capacity waggon, container, the great door of warehouse uniform thickness.

Background technology

The locking mechanism of railway freight-car car door mainly contains two purposes, and the one, in normal operation, guarantee reliable closure under the various again external force effects, the 2nd, prevent artificial unlatching, the theft goods.

At present lorry locking mode mainly contains 1, the lock of lock ring and pin with lock forms, and behind the closing of the door, the lock ring returning buckle is on lock, and lock pin falls, and realizes locking.2, compress bail and hold-down ring and form, this device can make the car door tight closure, but the handle in the hold-down ring device also will be fixed by the detent configuration in first kind.3, hasp lock.These several structures all can not prevent artificial unlatching, and the key strange land of haulage vehicle is transmitted very inconvenient, often will adopt the way of solid welding to more important goods, has no doubt played antitheft effect, but the goods yard staff opens difficulty equally, influences operating efficiency.On the other hand, various in the market theftproof locks substantially all are at small-sized door, lock core is directly controlled dead bolt with door locked, for large-scale thick and heavy iron gate, it is obviously unable to do what one wishes to only depend on key or dial directly to stir keeper, so market presses for a kind of firm, antitheft and door latch structure that the goods yard staff can conveniently open.

Summary of the invention

The purpose of this utility model is to provide a kind of high capacity waggon car door theftproof lock that dial control is combined with manual keeper, and is both firm antitheft, convenient again the unlatching.

The technical solution of the utility model is achieved in that this lorry car door theftproof lock, basic structure comprises: lock housing, lock core, the encoder of keyhole is set, it is characterized in that: the lock body internal upper part is provided with dead bolt, and the bottom is provided with encoder, the dial gap of encoder cooperates with the dead bolt pin, with the dead bolt correspondence position keeper slideway is set in the lock body, the protruding dogging of keeper one end is on dead bolt, and other end frame is held on the keeper seat.

The lock housing external surface of described lorry car door theftproof lock is provided with manual dead bolt and promotes the hole.

In the lock housing of described lorry car door theftproof lock the dead bolt slideway is set.

In the lock housing of described lorry car door theftproof lock and the keeper seat keeper slideway is set, keeper is inserted in the slideway.

The basic structure of the encoder of described lorry car door theftproof lock comprises the number dial, and the lock core of dial is set, and a plurality of dials are set on the lock core, and keyhole is established at the lock core center.

The keyhole of described lorry car door theftproof lock is triangle, square or other polygon.

The keyhole of described lorry car door theftproof lock constitutes by inside and outside two sections, and outer section is a cylinder, and inner segment is the polygon of circumscribed circle diameter greater than outer section internal diameter.

The encoder of described lorry car door theftproof lock is equipped with the private dialup key with lock core endoporus form fit.

The private dialup Key structure of described lorry car door theftproof lock comprises control handle, be arranged at key bar and sleeve pipe in the middle of the handle, and the key bar end is provided with telescopic polygon key, and is flexible by being arranged between the handle control of the spring on the key bar.

The polygon cylinder of the private dialup key of described lorry car door theftproof lock is provided with the elasticity spreading mechanism.

Lorry car door theftproof lock provided by the utility model utilizes dial control dead bolt, and manually the heavy keeper of push-and-pull can play the effect that art is good for strength, and private key is solid and reliable, and the thief uses the structure that general purpose tool is pounded, the sled activity all can not destroy lock; The utility model is easy for installation, operation and convenient management.

The specific embodiment

Fig. 1, Fig. 2, Fig. 3 are the schematic diagram and the sectional views of the structure of the utility model lorry car door theftproof lock locking state, among the figure as can be seen, the novel invention thought of this use is with the moving up and down of dial control dead bolt 6, and makes it to realize the locking to heavier relatively keeper.The basic functional principle of unblanking comprises: insert lockhole 9-4 rotary dial with key 11, gap 9-1 and dead bolt pin 6-1 on the dish are coincide, dead bolt 6 relies on gravity to fall, and keeper 3 can be extracted car door opening out from slideway 2.Need manually dead bolt to be carried knob 6-2 when locking a door and lift, rotary dial makes it dead bolt 3 and is stuck on the keeper hook.Fig. 4 Fig. 5 has provided the structure of dead bolt respectively, and Fig. 6 and Fig. 7 have then provided the location diagram of inner keeper slideway of lock housing and dead bolt.

The basic structure of encoder 9 comprises dial 9-2, dial 9-3, and lock core 9-5 establishes gap 9-1 on the dial 9-2, and keyhole 9-4 is established at the lock core center.For further antitheft, keyhole 9-4 constitutes by inside and outside two sections, and outer section is interior cylinder, and inner segment is the polygonized structure of circumscribed circle diameter greater than outer section internal diameter; Encoder 9 can be equipped with private key or general with the railcar door key.

The technical scheme that the utility model extends also comprises and has designed the private key 11 that cooperates with theftproof lock, Fig. 8 shows that this key is to rely on the polygon cylinder to cooperate with lockhole 9-4, when unblanking sleeve pipe 11-7 is inserted in the encoder keyhole 9-4, the key handle of holding with a firm grip 11-1 and 11-3 are by guide pillar 12, spring 11-9 presses down key bar 11-4 is released from sleeve pipe 11-7, the polygon post part 11-6 of key end struts, and cooperates with the keyhole polygonal hole, and rotation gets final product.
