Interior cooperation, bottom plate top left side are horizontally installed with the first cylinder, and the telescopic rod of the first cylinder is connect with sliding block left side lower part, bottom
Plate top left side is equipped with supporting plate, and supporting plate right side top is equipped with placing frame, and placing frame is located at plug directly to the left.
Further, further including having fixed device, fixed device includes link block, frame, fixed link, casing, bullet
Spring, pull ring, fixture block and 7 type kellies, placing frame right upper portion rotary type are equipped with link block, and the installation of link block bottom is framed
Frame, base of frame are equipped with fixed link, and fixed link lower part is cased with casing, is connected with bullet between bottom in fixed link bottom end and casing
Spring, casing outer bottom are equipped with pull ring, and face lower part is done outside casing and is equipped with 7 type kellies, is equipped with card on the right side of placing frame outer bottom
Block, fixture block and 7 type kellies cooperate.
Further, further including having 7 type bars, contact block, button and counter, top guide sleeve top center is equipped with 7
Type bar, 7 type bar right ends are equipped with contact block, and riser left side top is equipped with counter, counter left lower be equipped with by
Button, button and counter have circuit connection, and button, which is located on the right side of contact block, to be in contact with it.
Further, further including having fixed plate, the second cylinder and fixed block, frame right face lower part is equipped with fixation
Plate, fixed plate bottom right is vertically-mounted the second cylinder, and fixed block, fixed block left side are equipped on the telescopic rod of the second cylinder
Face is connect with casing external right side face top.
It is operated first personnel jack body is put into placing frame, restarts the first cylinder, the telescopic rod contracting of the first cylinder
Short strip movable slider is moved to the left, and sliding block, which is moved to the left, drives riser to be moved to the left, and then the component on riser is driven to be moved to the left,
And when plug is moved to the left on the right side of the jack of jack body, the first cylinder can be closed, operator is pinned slotting with hand
Seat ontology can start motor, and motor rotation band moving cam rotates, and cam rotation drives framework to move left and right, and framework or so is moved
Dynamic that mounting plate is driven to move left and right, mounting plate, which moves left and right, drives plug to move left and right, and plug is moved left and right to be connect with jack body
Touching, and then insertion jack body repeatedly, and resistance to slotting degree is carried out to jack body and is detected.When the resistance to slotting degree detection of jack body
After the completion, motor can be closed, the elongated movable slider for restarting the first cylinder moves right, and it is extensive to drive plug to move right
Again to original position, the first cylinder is closed, can jack body can be taken out and see and use by operator.
Because further including having fixed device, fixed device include link block, frame, fixed link, casing, spring, pull ring,
Fixture block and 7 type kellies, placing frame right upper portion rotary type are equipped with link block, and link block bottom is equipped with frame, framework bottom
Portion is equipped with fixed link, and fixed link lower part is cased with casing, is connected with spring in fixed link bottom end and casing between bottom, outside casing
Bottom is equipped with pull ring, and face lower part is done outside casing and is equipped with 7 type kellies, is equipped with fixture block, fixture block and 7 on the right side of placing frame outer bottom
The cooperation of type kelly, the personnel of being operated first pull pull ring to move down, and pull ring, which moves down, drives casing to move down, and spring is drawn
It stretches, casing, which moves down, drives 7 type kellies to move down, and 7 type kellies, which move down, not to be contacted with fixture block, i.e., openable frame,
Jack body is put into placing frame again.When jack body is located in placing frame, frame can be closed, pull ring is unclamped, because of bullet
The effect of spring, casing, which moves up 7 type kellies of drive and moves up, to be restored to original position, and then 7 type kellies and fixture block cooperate frame
Frame is fixed, can slotting degree resistance to jack body detect.It similarly, can be again after the completion of the resistance to slotting degree detection of jack body
Pull ring is pulled to move down, and then 7 type kellies are not contacted with fixture block, i.e., jack body is taken out, turns off frame by openable frame
Frame unclamps pull ring, and then 7 type kellies restore to original position.In this way, can prevent jack body from falling out out of placing frame, without
Jack body is pinned in operation, time saving and energy saving.
Because further including having 7 type bars, contact block, button and counter, top guide sleeve top center is equipped with 7 type bars, 7 types
Bar right end is equipped with contact block, and riser left side top is equipped with counter, and counter left lower is equipped with button, button with
Counter has circuit connection, and button, which is located on the right side of contact block, to be in contact with it, and when the motor is energized, plug is moved left and right to socket sheet
Body carries out resistance to slotting degree and is detected, meanwhile, framework is moved left and right drives guide sleeve to move left and right by connecting rod, and top guide sleeve or so moves
Dynamic that 7 type bars is driven to move left and right, 7 type bars, which move left and right, drives contact block to move left and right, and contact block, which moves left and right, carries out button
It presses, and then counter is made to be actuated for counting.When number of the plug to jack body reaches predetermined number of times, electricity can be closed
Machine.In this way, can more intuitively see the number that plug inserts jack body.
Because further including having fixed plate, the second cylinder and fixed block, frame right face lower part is equipped with fixed plate, fixed plate
Bottom right is vertically-mounted the second cylinder, and fixed block, fixed block left side and casing are equipped on the telescopic rod of the second cylinder
The connection of external right side face top, the personnel that are operated first start the second cylinder, and the telescopic rod elongation of the second cylinder drives fixed block downward
Mobile, fixed block, which moves down, drives casing to move down, and casing, which moves down, drives 7 type kellies to move down, and then 7 type cards
Bar is moved down not to be contacted with fixture block, closes the second cylinder, i.e., jack body is put into placing frame by openable frame.Similarly,
After jack body is located in placing frame, frame is closed, the telescopic rod for restarting the second cylinder, which shortens, drives fixed block to moving up
It is dynamic, and then drive 7 type kellies to move up and restore to original position, and frame is fixed, close the second cylinder.In this way, without operation
Personnel pull pull ring, convenient and efficient.
The present invention passes through fixed device, and jack body can be fixed, and prevents jack body from falling out of placing frame
Out, and by counter, the number that plug inserts jack body can be more intuitively known, has reached time saving and energy saving, without people couple
Jack body is detected, and the effect that work efficiency is high.
