The most convenient and safe way to unlock

The existing ordinary core door lock mainly uses the lock tongue limit method, the lock core is usually exposed, and a key corresponds to open a lock. While running on the railway, the railway equipment is very large, when used will carry a very large number of keys, while the railway equipment operation range is extensive, all over the country is possible to stay, the key transfer is very difficult, while the use of natural rain and dust easy to make door locks difficult to open, and can not prevent man-made damage, abnormal opening of the door lock.The most convenient and safe way to unlock

Technology implementation elements:

The purpose of the utility model is to provide a container door lock that is energy-efficient and anti-theft and can use the special railway key.

In order to achieve the above purposes, the container door lock designed by the utility model includes the locking body fastened to the container door plate and the lock box welded to the container lock rod; The locking rod that is articulated with the other end of the upper articulation rod and the lower locking rod that is articulated with the other end of the lower hinger rod, as well as the lock cover fastened to the door plate; The bottom of the lock core passes through the lock core hole of the lock cap until the lock head of the lock core is attached to the outer side of the lock cover, and the bottom of the lock core is connected to the lock seat;

The lock box comprises a lock box body, a locking plate set on the side plate on the body of the lock box and a lower locking plate set on the lower side panel of the lock box body, and the locking plate is opened with a cap hole for the head insertion of the locking rod, and the lower locking plate is opened with a lower-limit hole for the lower locking rod head insertion, The cover plate of the lock box body is opened with a key hole for special key insertion, and the lock box hides all the lock body inside the lock box.

1. The lock head of the lock core extends outwards with an extension shaft, and the head of the protruding shaft passes through the keyhole.

2. The lock head of the lock core is an asymmetrical outer five-party structure or heterostructure, which matches the asymmetric inner five-party structure or the opposite-sex structure of the special key;

3. The gap between the extended shaft and the keyhole is 3 to 5 mm.

4. The top of the lock base and the articulation point of the upper articulation rod, the articulation point of the upper articulation rod, the hinge bottom end of the lock base and the articulation point of the lower hinge rod, and the articulation point of the lower hinge rod and the articulation point of the lower locking rod.

Compared with the existing technology, the utility model has the following advantages:

1, the use of two ends fixed lock body, the form of the lower locking rod, so that welded on the container lock rod lock box to limit the rotation of the container lock rod, so as to achieve the locking of the door plate, and also prevent the door plate abnormal opening;

2, the lock core of the lock head extended outward through the keyhole out of the outstretched shaft, and the gap between the outstretched shaft and the keyhole is 3 to 5mm, in the process of application, on the one hand, the lock body can play an effective rain and dust protection role, on the other hand can avoid man-made damage to open the container door panel;

3, the lock core of the lock head for the asymmetric outer five-party structure or the opposite-sex structure, with the special key asymmetric inside the five-party structure or the opposite-sex structure to match, in addition, the special key is also set with the lock core outofing shaft matching the inner round hole, a special key can open all door locks, the use of maintenance railway equipment does not need to carry a large number of keys;

4, because the lock core is hidden in the cover, not using a special key is difficult to open the door lock of the utility model, therefore, anti-theft performance is good.
