Brief description
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of locking system in Fig. 1；
Fig. 3 is the structural representation of door handle device in Fig. 1.
Specific embodiment
As shown in figure 1, a kind of classroom door finger pinch device, including the locking system 1 being loaded on a upper limb be loaded on a middle part
The door handle device 2 of position and the steel wire line component 3 connecting locking system 1 and door handle device 2, door handle device 2 passes through wire
Assembly 3 controls locking system 1.
As shown in Fig. 2 locking system 1 includes the base 1-1 being fixed on a upper limb, base 1-1 is vertically arranged with latch
1-2.The bottom of latch 1-2 is arranged on plug housing 1-3, and the top of latch 1-2 is provided with positioning sleeve 1-4.Rocker-arm link 1-6's
One end and base 1-1 chain connection, can be rotated centered on junction point, and the other end passes through latch 1-2 to arrange.Back-moving spring 1-
5 are nested with outside latch 1-2, and its one end is located in plug housing 1-3, and the other end is contacted with rocker-arm link 1-6.
As shown in figure 3, door handle device 2 includes being arranged on a handle base 2-1 for middle part handling position, handle base 2-1 sets
It is equipped with rotor 2-2, the eccentric position of rotor 2-2 has grip hole 2-3, and the installed part of handle is arranged in grip hole 2-3
(in figure is not given), rotor 2-2 can be rotated centered on grip hole 2-3.
Steel wire line component 3 includes being driven steel wire 3-1 and supporting sleeve 3-2；One end of transmission steel wire 3-1 and rocker-arm link 1-
