Description
Technical Field
The utility model relates to the technical field of locks, in particular to a clutch transmission device which is arranged in a handle of an electronic lock.
Background
The door handle is an important component of the door lock, and the door lock can be opened by controlling the door handle to drive the door lock transmission piece to rotate. In the prior art, the handle of the electronic door lock is only a component for transmitting the twisting unlocking force of people, and is generally solid, and even if the handle is of a hollow structure, the built-in space is very narrow, so that people usually design a complex clutch control mechanism and electronic components of the electronic door lock in a lock body instead of the handle, and because the lock body has enough space to accommodate all detection and automatic control mechanisms, the lock body structure is generally large in size, high in price and inconvenient to install and maintain.
The clutch control mechanisms of the electronic door locks currently on the market are divided into two types. The clutch is arranged on the electronic lock panel, the clutch controls the disconnection and connection of the electronic lock handle and the square rod, so that the square rod can transmit the rotation of the handle to the lock body when the clutch is closed, and the door is opened. The lock has the advantages that the lock body is a pure mechanical part, the reliability is relatively good, and the cost is relatively low. However, the problem of large adaptability exists, the mechanical lock body on the market is various at present, the various dimensions of the square rod position are not unified, more trouble is that some mechanical lock bodies can only open one inclined tongue for the square rod connecting hole outside the door, and the requirement of opening all lock tongue functions of the electronic lock cannot be met. Therefore, when the electronic lock is installed, the original lock body on the door needs to be removed, and the normal operation of the electronic lock can be ensured only by replacing the mechanical lock body matched with the electronic lock. The other type is that the clutch is arranged in the lock body, the door handle is connected with the square rod hole on the lock body in the door through the square rod, the electronic module controls the clutch in the lock body to enable the square rod hole of the lock body to be connected and closed with the actuating mechanism of the lock body after authentication is passed, and therefore the square rod can convert the force on the handle into the force of the lock tongue for controlling the lock body, and accordingly door opening is achieved. The mechanical lock body on the door of the electronic lock in the lock body of the clutch must be replaced in the process of installing the electronic lock, and the process of disassembling the lock body is faced by the same type of electronic lock. Since the opening of a new lock body in a door may be different from the position of the lock body during the replacement of the lock body, a new opening in the door is required. Even worse, the position and size of the insertion hole of the bolt on the door frame also need to be adjusted according to different lock bodies. The original structure of the door and the door frame is damaged by the installation mode, which is called as destructive installation in industry, the original door and the door frame of a user are damaged directly, and the replacement of the door and the door frame is caused by the working errors of an installer, so that great trouble is brought to the user. More troublesome, because the lock bodies selected by the electronic locks are different from one another, the door and the door frame are likely to be damaged again when the user replaces other electronic locks.
On the one hand, how to solve the non-destructive installation will be an important issue for the electronic lock aftermarket. On the other hand, in order to reduce the cost and the volume of the electronic door lock and realize the function of electronic unlocking, technicians have made an effort to search whether all the functions of electronic control of the door lock can be realized in the rear handle, and a clutch driving mechanism provided in the rear handle is a key component.
