Description

Mechanical door lock that can recognize the locked state

technical field

The utility model relates to a mechanical door lock, in particular to a mechanical door lock capable of identifying a locked state, and belongs to the technical field of mechanical door locks.

Background technique

A door lock is a device used to lock the door to prevent others from opening the door. This device may be mechanical or electric, and electric power requires electric energy.

At present, mechanical door locks are widely used in external door locks. After the door is closed, the mechanical door lock cannot tell whether the door is locked or not. It is necessary to try to open the door to see if the door is locked, which increases the repeatability of the operation.

Contents of the invention

The technical problem to be solved by the utility model is: to provide a mechanical door lock with high control accuracy and identifiable locked state, which overcomes the disadvantage that the appearance of the existing mechanical door lock cannot distinguish whether the door is locked or not.

In order to solve the above-mentioned technical problems, the technical solution of the utility model is to provide a mechanical door lock that can identify the locked state, which is characterized in that it includes a combination of a door handle and a door plug, and the middle of the combination of the door handle and the door plug With lock cylinder.

Preferably, the combination of the door handle and the door plug is composed of a door handle and a door plug, and a door plug is provided at both ends of the door handle.

Preferably, each of the door plugs is provided with at least two card slots.

The door lock of the utility model has a simple structure, provides door lock state recognition, and retro operation mode, and improves people's sense of security after locking the door. The state of the door lock is determined by the position of the door handle, rather than the degree of rotation of the key, which improves the accuracy of control. The mechanical door lock can not only distinguish whether the door is locked, but also has a simple structure and high safety.

Description of drawings

Fig. 1 is a structural schematic diagram of a mechanical door lock that can identify the locked state in the locked state;

Fig. 2 is a structural schematic diagram of a mechanical door lock that can identify a locked state in an open state.

In the figure, 1 is a combination of a door handle and a door plug, 1-1 is a door handle, 1-2 is a door plug, 1-3 is a card slot, 2 is a lock cylinder, 3 is a door, and 4 is a wall.

Detailed ways

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

The utility model is a mechanical door lock that can identify the locked state, as shown in Figure 1, which is a structural schematic diagram of a mechanical door lock that can identify the locked state in the locked state. A combination body 1 of a door handle and a door plug and a lock core 2 are installed on the door 3, and the lock core 2 is located in the middle of the combination body 1 of the door handle and the door plug.

The combination 1 of the door handle and the door plug is composed of a door handle 1-1 and a door plug 1-2, and a door plug 1-2 is welded at both ends of the door handle 1-1. Each door plug 1-2 is provided with at least two card slots 1-3. When the door 3 is locked, the position of the door plug 1-2 changes, and the change of the position of the door plug 1-2 causes the change of the position of the door handle 1-1. Turn the lock cylinder 2 with a key and pull the door handle 1-1, the door handle 1-1 can drive the door plug 1-2 to move laterally, and complete the locking and opening functions of the door lock. The position of the door handle 1-1 on the door 3 shows the locked state of the door lock, and the position of the door handle 1-1 can identify whether the door is locked.

In FIG. 1 , the lock cylinder 2 is stuck in the slot 1-3 on the combined body 1 of the door handle and the door plug, and the part of the door plug 1-2 enters the wall 4 . When the door 3 needs to be opened, the key turns the lock cylinder 2, the combination 1 of the door handle and the door plug is in a free state, the combination 1 of the door handle and the door plug is pulled out to the right, and the door 3 is opened, as shown in Figure 2 It is shown that when the door lock is opened, the combination 1 of the door handle and the door insert is exposed outside the door lock structure, and is recognized by the user as an open state.

Claims (1)

1. the mechanical door lock that can identify locking states, it is characterized in that, comprise door handle and the slotting combination (1) of door, the middle lock core (2) that is provided with of combination (1) that door handle and door are slotting, the slotting combination (1) of described door handle and door is inserted (1-2) by door handle (1-1) and door and is formed, the two ends of door handle (1-1) are equipped with a door and insert (1-2), and each door is inserted (1-2) and is provided with at least 2 draw-in grooves (1-3).
