Background
The power supply lock adds a lock to the power supply switch to control the on-off of the power supply. At present, there is a power lock on the market, its structure mainly includes the circuit board, the switch, lock shell and lock core, be provided with on the lock core with switch complex lug, rotate through the control lock core, make the contact on the lug extrusion switch, and then the switching of control power, and for the ease of resetting of lock core, a draw-in groove is generally seted up on the lug, and go into this draw-in groove with the spring foot card of torsional spring, can extrude the torsional spring when the lock core rotates, later recycle the elasticity of torsional spring and drive the lock core and carry out quick reset, but discover in the in-service use, the spring foot of torsional spring is deviate from in the draw-in groove very easily, its practicality and stability are relatively poor, can't satisfy user demand.
Disclosure of Invention
In view of the not enough of background art, the utility model aims to solve the technical problem that a simple structure is provided, reasonable in design effectively improves the reliability that the lock core moved and reset, and then promotes the high stability power lock of the stability that the power lock used.
Therefore, the utility model discloses an adopt following scheme to realize:
high stability power lock, including bottom and the lock shell that links together, be provided with the circuit board in the bottom, rotationally be provided with the lock core in the lock shell, be provided with the switch on the circuit board, the bottom of lock core be provided with switch complex lug, its characterized in that: the lock comprises a lock core, and is characterized in that a torsion spring mounting groove is formed in the lock core, a torsion spring is arranged in the torsion spring mounting groove, two spring feet of the torsion spring are arranged and are led out of the opening end of the torsion spring mounting groove, and extend into a yielding groove in the lock shell, and the two sides of the yielding groove are provided with pressing surfaces for the spring feet to lean against.
The bottom of lock core has the annular arch, the torsional spring mounting groove by the annular arch encloses out, the annular arch has the opening, the protruding open-ended both ends of annular form and supply the spring foot to support the contact surface that resets that leans on.
And the circuit board is electrically connected with a plug connector.
The outer side wall of the lock shell is provided with a buckle, and the side wall of the bottom cover is provided with a buckle hole matched with the buckle.
Adopt above-mentioned technical scheme, the utility model discloses an advantage does: through setting up the torsional spring mounting groove on the lock core, with torsional spring body direct mount on the lock core, the spring foot of torsional spring stretches into the inslot of stepping down on the lock shell, and the both sides in groove of stepping down have and supply the spring foot to lean on the face of pressing by what lean on, so both can effectively guarantee the torsional spring installation back and can not deviate from, can ensure the spring foot again and lean on face complex reliability, effectively guarantee going on smoothly of lock core operation that resets, and then promote the practicality and the stability of power lock.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a view of the split structure of the present invention;
FIG. 2 is a structural diagram of the lock cylinder of the present invention;
FIG. 3 is a structural diagram of the lock core of the present invention installed on the lock case;
fig. 4 is a view of fig. 3 from another perspective after the addition of a switch.
Detailed Description
As shown in the figures, the high stability power lock disclosed by the utility model comprises a bottom cover 1 and a lock case 9 which are connected together, in the embodiment, a buckle 8 is arranged on the outer side wall of the lock case 9, a buckle hole 2 matched with the buckle 8 is arranged on the side wall of the bottom cover 1, the bottom cover 1 and the lock case 9 can be connected by clamping the buckle 8 into the buckle hole 2, the operation is very convenient, a circuit board 3 is arranged in the bottom cover 1, a lock core 11 is rotatably arranged in the lock case 9, a switch 4 is arranged on the circuit board 3, a lug 10 matched with the switch 4 is arranged at the bottom of the lock core 11, a torsion spring mounting groove 12 is arranged on the lock core 11, a torsion spring 7 is arranged in the torsion spring mounting groove 12, two spring feet 6 of the torsion spring 7 penetrate out from the opening end of the torsion spring mounting groove 12 and extend into a yielding groove 15 on the lock case 9, two sides of the yielding groove 15, further, the bottom of lock core 11 has annular bulge 16, and torsional spring mounting groove 12 is enclosed by annular bulge 16, and annular bulge 16 has the opening, and annular bulge 16 open-ended both ends form the contact surface 17 that resets that supplies spring foot 6 to support against, guarantee that the location of spring foot 6 is worn out to promote the stability and the reliability that spring foot 6 resets. In addition, a connector 5 is electrically connected to the circuit board 3, and the connector 5 may be a power lamp for displaying the on/off state of the power supply.
