The power supply hole 44 is electrically connected with the wire 51, and the wire 51 is telescopic wire, and the locking mechanism 45 includes
The sliding chamber 451 of locking and the monocline face tapered end 454 being arranged in the sliding chamber 451 of the locking, monocline face tapered end 454 is close to institute
State the sliding inner side of chamber 451 of locking and be provided with magnet apparatus 455, monocline face tapered end 454 is away from the lateral institute of the magnet apparatus 455 1
State and extend in locked groove 46 and stretch into the locked groove 46, the relative locking of the magnet apparatus 455 is slided in chamber 451 provided with electricity
Magnetic coil means 452, the magnet apparatus 455 is wrapped around provided with second back-moving spring with the electromagnetic spool device 452
453, the (the first back-moving spring 33 is brute spring, and the elastic force of the (the first back-moving spring 33 is more than the extension spring 52
Elastic force, when (the first back-moving spring 33 returns back to Fig. 2 left-most position, its Flexible Reset power is still greater than extension spring 52
Tensile force, grafting sliding block 31 is reset to the left-most position shown in Fig. 2.
Original state is, screw shell 23 is slided in chamber 22 first, does not extend out outside power supply first 2, and grafting sliding block 31 passes through the
One back-moving spring 33 is pushed up to the leftmost side that chamber 3 is slided second, and power supply block 43 pulls to the most right of power supply chamber 4 by extension spring 52
Side.
In use, when needing to electrically connect on power supply head and Power Block realization, passing through the second motor 25 and driving the second screw rod
24 are rotated so that screw shell 23 is stretched out outside power supply first 2, and the distance that screw shell 23 stretches out power supply first 2 is powered than the stretching of contact pin 21
Big a certain distance of distance outside first 2 so that after contact pin 21 slides chamber 3 completely into second, screw shell 23 can be by grafting
Sliding block 31 promotes to the right corresponding distance, although to ensure that now contact pin 21 has been fully located in the second cunning chamber 3, will not be with
Jack 32 is contacted, and is then driven the first screw rod 14 to rotate by the first motor 15 and is caused slider guide 13 to drive power supply first 2 to power supply
Move the side of portion 12 so that the right side of screw shell 23 is abutted against with the left side of grafting sliding block 31, because the first motor 15 drives
First screw rod 14 is rotated further, and makes grafting sliding block 31 overcome the active force of (the first back-moving spring 33 to push away grafting sliding block 31 to the right
Dynamic, now contact pin 21 is progressed into the second cunning chamber 3, but is due to that grafting sliding block 31 moves right in advance so that contact pin
21 will not contact with jack 32 all the time, while drive the double inclined plane tapered end 42 on power supply bar 34 and solid sliding block 41 to move to the right,
When double inclined plane tapered end 42 is moved in locked groove 46 and is abutted against with monocline face tapered end 454, monocline face tapered end 454 is set to overcome second to answer
The active force of position spring 453 is moved into the sliding chamber 451 of locking, when double inclined plane tapered end 42 is abutted against with the madial wall of locked groove 46, now,
Monocline face tapered end 454 is headed into monocline face tapered end 454 in locked groove 46 and and double inclined plane by the active force of second back-moving spring 453
The locking connection of tapered end 42, meanwhile, the right side of power supply first 2 is abutted against with the left side of power supply 12, in the right-hand member of the power supply first 2
When face and the left side of the power supply 12 are abutted against, the sealing strip 57 is also inserted into the seal groove 58 and engages to play
Sealedly effect, adds the sealing that the right side of the power supply first 2 and the left side of the power supply 12 are abutted against, then
By controlling the second motor 25 to invert screw shell 23 is slipped into the first cunning chamber 22, now, due to (the first back-moving spring 33
Active force cause grafting sliding block 31 while driving double inclined plane tapered end 42 and power supply block 43 on solid sliding block 41 to overcome extension spring
52 active force is moved to the left, because the elastic-restoring force of (the first back-moving spring 33 is more than the tensile force of extension spring 52, is made
Must power block 43 and double inclined plane tapered end 42 can together with to left movement, and the elastic-restoring force of spring 33 can be 31 times by grafting sliding block
The multiple high order end that chamber 3 is slided to second, meanwhile, contact pin 21 is gradually inserted in jack 32, until grafting sliding block 31 moves to the second cunning
During the high order end of chamber 3, in the fully-inserted jack 32 of contact pin 21, electric completion is now connect.
When needing out of Power Block to extract power supply head to power off, the second motor 25 of control, which is rotated, causes screw shell 23
Again stretch out to compress grafting sliding block 31 so that grafting sliding block 31 drives double inclined plane tapered end 42 and power supply block 43 on solid sliding block 41
Move right, until sliding block grafting sliding block 31, solid sliding block 41, double inclined plane tapered end 42 and the overall structure movement of the power supply formation of block 43
To the low order end for chamber 4 of powering, and in the process, contact pin 21 is gradually extracted from jack 32, until power supply block 43 moves to confession
During the low order end of electric chamber 4, contact pin 21 is extracted completely out of jack 32, and power supply first 2 is electrically connected with the separated of Power Block 1, then
By producing attraction between electricity and magnet apparatus 455 on electromagnetic spool device 452 so that monocline face tapered end 454 overcomes second
The active force of back-moving spring 453 is moved into the sliding chamber 451 of locking, until monocline face tapered end 454 is released and double inclined plane tapered end completely
42 fixing, then controls the reversion of the first motor 15 to remove power supply first 2 out of Power Block 1, completes unblock and powers off；This
Inventive structure is simple, can effectively prevent non-inserting state cause accidental shock may, and can realize and automatically control grafting, raising is slotting
Meet stability and reduction human contact and cause electric shock may.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
The change or replacement expected without creative work, should all be included within the scope of the present invention.Therefore, it is of the invention
Protection domain should be determined by the scope of protection defined in the claims.
