The sliding set to extend to the left, the sliding are provided with middle stomidium, are slid in the middle stomidium and be equipped with the bar that is electrically connected, the electricity in covering
Sliding is covered and is fixedly mounted in the resettlement groove right end wall described in connecting rod right end break-through, and described be electrically connected described in bar left end break-through is slided
It moves and covers and be installed with the block that is electrically connected, the sliding set left end mutually claims have the first oblique angle face up and down;By dividing in the distribution box
Partition board separate up and down be provided with it is at least more than two and with the matched data socket of the data pin, on the data socket
It is lower mutually claim to be provided with notch towards the right side and with the matched reeve slot of the block that is electrically connected, mutually claim to set in the reeve slot upper and lower ends wall
The slippage slot towards the reeve slot is equipped with, is slid in the slippage slot and slipping block is installed, slot is provided in the slipping block
Mouth spiral shell shape hole outwardly, in the spiral shell shape hole cooperation spiral shell shape bar is installed, the spiral shell shape bar and be fixedly mounted in data socket
Motor connection, the slipping block be installed with towards the end face for injecting slot abut plate and be electrically connected with city it is tactile
Block, the contact block are located at the abutting plate left end, and the plate that abuts is provided with and described first towards the end face for injecting slot
Matched second oblique angle in oblique angle face face, and it is described abut plate towards it is described inject slot end face middle-end at be provided with half arc slot,
It is additionally provided in the data socket and is spaced apart device, the device that is spaced apart includes heavy chamber and is spaced apart.
Further technical solution is also installed with the compression spring abutted with the sliding set in the resettlement groove, described
Compression spring makes the sliding set offset with the block that is electrically connected the sliding is covered top pressure to the left.
Further technical solution, described inject in slot left end wall are also equipped with the push button being connect with the motor, when
When the block that is electrically connected is inserted into the reeve slot and is contacted with the push button, the push button can control the motor running.
Further technical solution, the block left end that is electrically connected are provided with third oblique angle face, described so as to conveniently be inserted into
It injects in slot.
Further technical solution, the block that is electrically connected are equal with the sliding set shape and size.
Further technical solution, the distance for abutting plate left side to the data socket right side are electrically connected with described
The distance of block right side to the data pin left side is equal, so as to when the data pin left side and the data socket
When right side is bonded, second oblique angle face can be directed at first oblique angle face.
Further technical solution, the radius of the half arc slot are equal with the radius of the bar that is electrically connected.
Further technical solution, the heavy chamber, which is set in the data socket right end face, to be located at described in upper and lower two
It injects between slot, it is described to be spaced apart fixed setting in the heavy chamber, being spaced apart by described and circuit occur in the data socket
During failure, the data socket is automatically powered off, so as to improve Ability of emergency management, increase electrical safety.
The beneficial effects of the invention are as follows:
In original state, the slipping block is contracted in the slippage slot data socket in apparatus of the present invention completely, and institute
Abutting plate is stated to flush with the reeve slot inner wall towards described one end for injecting slot, and the contact block will not extend into reeve slot
In, it is injected in slot but during not in contact with to the push button if being at this time inserted into metal rod, metal rod will not be touched with described
Block contacts, and therefore, after will not charging artificial unexpected contact electric shock accidents will not occur for metal rod;
And when thicker metal rod is inserted into and injects in slot and contacted with the push button, it is supported described in the electronic opportunity driven
Fishplate bar is extend into the reeve slot, and abutting can not just continue to slide after plate offsets with metal rod, and therefore, the contact block is still
Old can not extend into is injected in slot, and metal rod will not be contacted with the contact block, and even if when metal rod is thinner, due to contact block
Positioned at the abutting plate left end, therefore, metal rod can not still touch contact block, therefore electric shock accidents will not occur;
In use, the block that is electrically connected is inserted into the reeve slot, when the data pin left side and the data socket
When right side is bonded, the motor can drive the slipping block to be slided towards the reeve slot, and the slipping block slip can band
The dynamic abutting plate and contact block are slided towards the reeve slot, since second oblique angle face may act on first oblique angle
Face, so as to which the abutting plate can drive the sliding set to slide to the right, when half arc slot on the abutting plate and the bar that is electrically connected
When matching, the contact block offsets with the block outer end face that is electrically connected, and thus can alternating current be transmitted to data equipment, so as to fulfill number
According to the energization of equipment;
Since when data equipment is powered, the abutting plate can prevent the block that is electrically connected from extracting to the right, therefore, the abutting plate can
The block that is electrically connected is locked in the reeve slot, when someone, which accidentally kicks, encounters data pin, data pin will not be caused
Loosening, therefore, the phenomenon that accident power-off will not occur;
Apparatus of the present invention are simple in structure, easy to use, and electrical safety is high, can substantially reduce security risk, can make powered stable.
