The first spiral shell shape bar stretches to both sides to be set, symmetrical on two pack supports on the right side of the gliding member to be provided with clamping chamber, institute
State two groups of clamping chamber opposite sides and be provided with clamping apparatus, the peace socket part inwall on the right side of the lock chambers is provided with and the locking
The introducing port that chamber is connected, the enforcement division lower section are provided with billboard An Jie areas, and the enforcement division bottom right side is provided with gear fishplate bar,
The first slide slot is provided with the enforcement division between the gear fishplate bar and peace socket part, is provided with and slides in first slide slot
Block, whorl is connected with the second spiral shell shape bar in the sliding block, and the second spiral shell shape bar stretches to both sides to be set, the sliding block
Inside be provided with the second slide slot, be provided with second slide slot and lead shifting bar, it is described lead to move slidably connect peace on bar and connect frame, it is described
Peace connects frame and stretches setting downwards, and the peace connects frame stretch section in the billboard An Jie areas, in the billboard An Jie areas
The peace connect frame rear end face and be provided with card chute, is provided with card sliding block in the card chute, the card sliding block, which is provided with, or so stretches
The check lock lever of exhibition, check lock lever left side stretch section are oppositely arranged with the introducing port, the check lock lever left distal end edge
Provided with the ramp-like face convex portion being slidably matched with the clamping apparatus, stretching, extension end is provided with advertisement peace and connects board on the right side of the check lock lever,
The gear fishplate bar end face outside is provided with the first flashing lamp and the second flashing lamp, and the peace moved below bar of leading connects frame or so
The first touch sensor and the second touch sensor, first touch sensor and are respectively equipped with the outer wall of both sides
Two touch sensors are electrically connected with first flashing lamp and second flashing lamp respectively.
Preferably technical scheme, extended end is rotatably connected to the first motor on the left of the first spiral shell shape bar, and described the
One motor is embedded in the peace socket part inwall and is fixedly connected, and extended end is rotated with the fixed block and connected on the right side of the first spiral shell shape bar
Connect.
Preferably technical scheme, the second spiral shell shape bar left side extended end and the peace socket part rotation connection, it is described
Extended end is provided with the second motor on the right side of second spiral shell shape bar, and second motor is in gear fishplate bar and is fixedly connected.
Preferably technical scheme, the clamping apparatus include the support on the gliding member and to the locks
Ramp-like face clamping convex portion that tight intracavitary stretches into, it is arranged on the magnetic patch device of ramp-like face clamping convex portion bottom and is arranged on the card
Connect the electric coil production magnetic device of intracavitary, wrapping around provided with bearing down on one between the magnetic patch device and electric coil production magnetic device
Spring element.
The beneficial effects of the invention are as follows：Snap fit onto peace by card sliding block first to connect in card chute on frame, then by the
Two motor controls the second spiral shell shape bar to rotate while drives sliding block and peace to connect frame and move to the left, when check lock lever is inserted by introducing port
Enter in lock chambers, and ramp-like face convex portion is offseted with ramp-like face clamping convex portion and be connected, move bar due to leading and connect frame with peace and be slidably connected,
Now, sliding block continues to move to the left so that the sliding block inwall of the second slide slot inner right side connects frame right flank phase with peace
Abut, meanwhile, drive ramp-like face convex portion inwardly to extrude so that ramp-like face clamping convex portion overcome the active force for the spring element that bears down on one and to
Clamping intracavitary move, when ramp-like face convex portion is moved fully to ramp-like face clamping convex portion backwards to side, now, sliding block left surface with
Peace socket part abuts against, and ramp-like face clamping convex portion is stretched out by the active force for the spring element that bears down on one into lock chambers, then passes through first
Motor control the first spiral shell shape bar, which rotates, drives gliding member to move to the left, at the same clamping apparatus drive ramp-like face convex portion and with
The peace of check lock lever connection connects frame and is moved to the left, and now, the leading shifting bar that peace is connect in frame and the second slide slot is slidably matched and to the left
Slide, because the length of the first spiral shell shape bar immobilizes, position of the fixed block in lock chambers also immobilizes, but due to this
When gliding member drive check lock lever and peace to connect frame and be moved to the left so that fixed block slides to the right relative to gliding member, therefore
Check lock lever is driven in gliding member and peace is connect during frame is moved to the left, and the bullet connection pad that fixed block its right end face is set is gradual
Ground abuts with check lock lever left end surface elastic, until peace connects sliding block inwall phase of the left surface with the second slide slot inside left of frame
Abut so that gliding member, check lock lever and peace connect frame and can not be further continued for moving to the left, and it is left with check lock lever now to play connection pad
Realize between end face and be tightly engaged into completely simultaneously, after check lock lever left side is tightly engaged into completely with playing connection pad, control the first horse
Up to stopping operating, complete to be fastenedly connected；When needing to extract, electricity on magnetic device is produced by electric coil and coupled with magnetic patch device, is made
Ramp-like face clamping convex portion overcomes the active force for the spring element that bears down on one and moved to clamping intracavitary, then pass through the second motor control the
Two spiral shell shape bars are rotated and remove check lock lever, and electric coil production magnetic device and the power-off of the second motor are controlled after the completion of removal.This hair
It is bright simple in construction, it can be realized by electric motor drive and be tightly engaged between bullet connection pad and check lock lever left side, reduce people
Work working strength, operating efficiency is improved, and can keep playing the elasticity between connection pad and check lock lever left side after such insertion
Locking is compressed, prevents peace from connecing unstable, steadiness is high, and when needing to extract, can easily unlock, be easy to later maintenance
And replacing.
