Description

Toggle shaft core of double-insertion type lock core

Technical Field

The utility model belongs to two formula lock cores fields of inserting, concretely relates to toggle axle core of two formula lock cores of inserting.

Background

At present, the commonly used lock core mainly comprises a lock body, an inner lock core part, an outer lock core part, a lock tongue shifting part and a shifting shaft core, wherein the inner lock core part and the outer lock core part are respectively positioned in lock core holes at two ends of the same lock body, key holes are respectively arranged on the inner lock core part and the outer lock core part, the existing shifting shaft core comprises a support shaft and shifting wheel cores (also called clutches), the two shifting wheel cores are respectively and movably sleeved on the support shaft, shifting blocks capable of driving the lock tongue shifting part to rotate are respectively arranged on the two shifting wheel cores, shifting block clamping grooves corresponding to the shifting blocks are respectively arranged at one ends of the inner lock core part and the outer lock core part close to the lock tongue shifting part, when the lock core is arranged on the anti-theft door, the inner lock core part and the outer lock core part are respectively positioned at two sides of the anti-theft door, and the shifting shaft core is pushed to move by inserting a key into the lock core holes on the inner lock, one side of a shifting block on a shifting wheel core inserted into one end of a key is clamped in a shifting groove of a spring bolt shifting piece, the other side of the shifting block is clamped in a shifting block clamping groove on a lock core, the shifting block is rotated by the rotation of an inner lock core part or an outer lock core part of a door under the driving of the key, and the shifting block rotates to drive the spring bolt shifting piece to rotate, so that the door opening or the door back locking is realized.

After the key is inserted into the lock cylinder on one side of the anti-theft door, the inserted key pushes the toggle shaft core to move towards the lock cylinder on the other side of the anti-theft door, so that the thumb wheel core which is not inserted into the key end moves out of the toggle groove on the lock tongue toggle piece, the inserted key rotates again to drive the lock tongue toggle piece to rotate, after the lock tongue toggle piece rotates, the toggle block on the thumb wheel core which is positioned outside the lock tongue toggle piece is staggered with the toggle groove of the lock tongue toggle piece, the toggle shaft core occupies the space which is not inserted into the lock cylinder on the key end, the length of the lock cylinder hole which is not inserted into the lock cylinder on the key end is shortened, the key is inserted into the lock cylinder on the other side of the anti-theft door under the state that the inserted key is not taken out, the inserted key cannot push the thumb wheel core which is staggered with the toggle groove of the lock tongue toggle piece to move, and the inserted key cannot be completely inserted into the lock, the key can not be rotated, so that the action of opening or locking the door can not be realized.

If a key is inserted into the key hole of the inner lock cylinder part of the door to open the door, the key can push the poking shaft core to move towards the outer lock cylinder part of the door, so that the poking wheel core matched with the lock cylinder part of the door is moved out of the poking groove on the lock tongue poking part, the door is opened by rotating the key, a person forgets to take out the key inserted into the key hole of the inner lock cylinder part of the door after going out, and the door is closed carelessly. In the same way, the method for preparing the composite material,

if a key is inserted into a key hole of a lock cylinder part at the outer side of a door to open the door, the key can push a poking shaft core to move towards the lock cylinder part at the inner side of the door, the door is opened by rotating the key, a person leaves the door and forgets to take out the key inserted into the lock cylinder part at the outer side of the door, and the door is closed carelessly. The current lock core is in daily use, forgets to take off the indoor key that inserts after opening the door when going out, and in careless closing the door, at this moment, outdoor people want to enter the room again, inserts outdoor outside door lock core portion with the same key and opens the door on, then the key can not insert outside door lock core portion completely at all in, cause the key can not rotate and can't open the door, often because of going to turn over the window and fall to die and fall to hinder, also often cause fire control officer to go to rescue and wasted manpower and materials (often there is such incident report on the TV), it is very inconvenient to use. When people in the room forget to take off the key after locking the door indoors for safety at night, people returning from the outside in the middle of the night can not insert the key from the outside to rotate to open the door, and only people who sleep in the room are waken to open the door. Similarly, when the door is unlocked from the outside and the key is forgotten to be removed when the door is taken out early, the indoor person cannot insert the key from the indoor and turn to open the door, and the indoor person cannot escape when an emergency such as a fire occurs. Therefore, the traditional mechanical lock cylinder of the anti-theft door is extremely inconvenient to use and brings troubles to daily life of people; in severe cases, the lock core can cause casualties and property loss or unexpected troubles, so that the original mechanical lock core cannot adapt to the requirements of the current life development of the door.
