The present embodiment for ease of description, rather than the device or element of indication or suggestion meaning must have a particular orientation, with
Specific orientation construction and operation.
In addition, the connection or fixed form between component if not otherwise specified in this embodiment, connection or solid
Determine mode can for fixed by bolt commonly used in the prior art or pin fix or bearing connection etc. modes, therefore, this
It is not described in detail in embodiment.
Embodiment
As shown in Figure 1-3, a kind of no cold bridge closed type overhauls door lock, 1 lock body for being provided with inner cavity including one, and setting
Lock core 2 inside 1 lock body, and the keyhole 3 being arranged on 1 lock body leading flank, and the handle hand below keyhole 3 is set
Handle 4, has been wholely set handle connecting rod 41 on the handle handle 4, the handle connecting rod 41 through lock body 1 and with lock core 2
It is flexibly connected, the keyhole 3 also extends through lock body 1 and connect with lock core 2, and the surface of the keyhole 3 is provided with logical with lock body 1
The first sealing device 5 that screw is fixed is crossed, is provided with the second sealing device 6 on the handle connecting rod 41；Described first
The hinged seat 51 that sealing device 5 is fixed using screw by one with lock body 1, and be arranged on hinged seat 51 and L-shaped set
