134 top of plate, the rotation drive of reversed column 120 are stirred flat axis 111 and are rotated so that unlocking board 134 moves up locking lock bolt 131, or makes
It obtains unlocking board 134 and moves down disengaging lock bolt 131.
By taking the side of double-sided lock 100 is opened the door as an example, rotated clockwise in use, key 20 is inserted into the first lock core 141, the
Reversed column 120 is driven to rotate for one tongue piece 142 so that stirring flat axis 111 pushes plectrum 135, and plectrum 135 then drives unlocking board 134 simultaneously
It moves downward, then the abutting of script unlocking board lock bolt more than 134 131 releases, and manually pulls the first handle 160 at this time so that double
Face lock 100 is opened.Similarly, when key 20 is inserted into the second lock core 151, unlock principle is same as described above.
Further, connection bump 136, one end and the connection bump 136 of plectrum 135 are provided on the shell of lock body 130
Rotation connection, the other end of plectrum 135 are provided with loose slot 137 along the length direction of plectrum 135, stir 111 activities of flat axis
In slot 137, the outer wall of plectrum 135 is arranged with the first spring 138, and the first spring 138 is located at the company of plectrum 135 and unlocking board 134
Contact is to stirring between flat axis 111.
When key 20 is inserted into lock core, key 20 is rotationally clockwise so that and it stirs flat axis 111 and is pressed downward plectrum 135,
The sliding in loose slot 137 of flat axis 111 is stirred at this time, and compresses the first spring 138, and plectrum 135 is whole to be moved down, and drives solution at this time
Jam plate 134 also moves down, lock release of the unlocking board 134 to lock bolt 131.After taking out key 20, bullet is being replied in the first spring 138
Under the action of power, unlocking board 134 is popped into position and continues to lock lock bolt 131.
Further, the shell of lock body 130 corresponds to the position on 134 top of unlocking board and is provided with positioning column 124, unlocking board
The length direction that unlocking board 134 is prolonged on 134 top is provided with locating slot 125, and positioning column 124 is located in locating slot 125.
Setting positioning column 124 and locating slot 125 enable unlocking board 134 move up or folding process do not generate it is crooked,
It positions more acurrate.
Further, double-sided lock 100 further includes first connecting rod 161 and second connecting rod 171, has gear in lock body 130
132, the center of gear 132 is provided with the mating groove 126 that shape is polygon, and one end of first connecting rod 161 is set to the
In one handle 160, the rotation of the first handle 160 can drive first connecting rod 161 to rotate synchronously, the other end of first connecting rod 161
It is set in mating groove 126, first connecting rod 161 is set to the shape of one end of mating groove 126 and the shape phase of mating groove 126
Match.One end of second connecting rod 171 is set in the second handle 170, and the rotation of the second handle 170 can drive second connecting rod
171 rotate synchronously, and the other end of second connecting rod 171 is set in mating groove 126, and second connecting rod 171 is set to mating groove 126
The shape of one end and the shape of mating groove 126 match.The connection type of connecting rod and handle can be welding.Can also be will even
