Detailed Description

The following description will explain embodiments of the present invention with reference to the drawings. As shown in fig. 1 to 8: a rotary socket with locking function comprises a rotary socket body 1, a first positioning block 3 and a second positioning block 4 are arranged on the outer circumference of the rotating part of the rotary socket body 1, a locking mechanism is matched with the rotary socket body 1,

The utility model discloses rotation type socket with locking function's working process as follows: in the initial state, under the action of the spring 7, the driving rod 6 is jacked up by the spring 7, at the moment, the driving pin 11 is positioned at the top end of the upper sliding chute 12, since the rectangular portion of the lower half of the drive rod 6 is attached to the square hole in the partition, the drive rod 6 can only move along the length of the housing 5, but can not rotate, at the moment, under the limit action of the driving pin 11, the upper sleeve 8 can not rotate, the two locking blocks 10 on the rotary socket body 1 can not rotate, at the moment, the first locating block 3 on the rotary disc 2 of the rotary socket body 1 is just positioned between the two locking blocks 10, namely the two locking blocks 10 limit the first locating block 3 in the front and back directions to ensure that the rotary disc 2 can not rotate, at the moment, the rotary socket is not electrified, even if external force acts on the rotary disc 2, the rotary socket body 1 cannot rotate to the power-on state due to the existence of the locking mechanism; (as shown in FIG. 3)

When the rotary socket body 1 needs to be switched to a power-on state, the driving rod 6 is pressed downwards, the driving rod 6 can drive the driving pin 11 to slide in the upper chute 12 when moving downwards, and after the driving pin 11 slides out of an opening at the bottom of the upper chute 12 and enters the lower chute, the driving pin can firstly slide in the inclined section 13 in the lower chute, because the driving pin 11 can only do longitudinal movement, the lower sleeve 9 can move downwards (relative to the upper sleeve 8) while rotating, in the process, the upper sleeve 8 cannot rotate (because the upper sleeve does not bear torque), and in the process that the lower sleeve 9 moves downwards, the positioning wedge 15 is separated from the first limiting groove 16 and gradually moves to the lower part of the second limiting groove 17 along with the rotation of the lower sleeve 9; (as shown in FIG. 4)

After the driving pin 11 enters the vertical section 14 from the channel at the bottom end of the inclined section 13, because the spring 7 at the bottom end of the driving rod 6 always provides upward force in one direction, the driving pin 11 will move upward from the bottom end of the vertical section 14 until contacting with the inclined surface at the top of the vertical section 14, and will be limited by the inclined surface, will not move reversely and will return to the inclined section 13 again, and the lower sleeve 9 will also rise relative to the upper sleeve 8 in the above process, at this time, the positioning wedge 15 enters the second limiting groove 17; in this state, since the driving pin 11 is disengaged from the upper sliding groove 12 formed in the upper sleeve 8, the upper sleeve 8 is restored to the degree of freedom in the circumferential direction and can rotate; (as shown in FIG. 5)

At the moment, a plug can be plugged into the rotary socket body 1, the rotary table 2 is rotated, and the upper sleeve 8 where the two locking blocks 10 are located can rotate, so that the locking blocks 10 can be shifted to act when the first positioning block 3 on the rotary table 2 rotates, the upper sleeve 8 is finally driven to rotate, and after the rotary table 2 rotates in place, the rotary socket body 1 is electrified and can work normally; when the upper sleeve 8 rotates, because the direction of the rotation of the upper sleeve 8 is consistent with the direction of the upper inclined surface of the positioning wedge 15, under the action of the inclined surfaces matched with the positioning wedge 15 and the second limiting groove 17, the lower sleeve 9 rotates while moving downwards relative to the upper sleeve 8 again, then under the action of the spring 7, the upper sleeve and the lower sleeve are contacted again, in the process, the positioning wedge 15 returns to the first limiting groove 16 from the second limiting groove 17 again, the relative position between the upper sleeve 8 and the lower sleeve 9 returns to the initial state again, the upper sliding groove 12 is communicated with the lower sliding groove again, and the difference between the initial state and the initial state is that the driving pin 11 is not in the upper sliding groove 12 but in the vertical section 14 at the bottom of the lower sliding groove; while the relative angles between the upper and

lower sleeves

8, 9 and the drive pin 11 are also different (as shown in fig. 6);

after the rotary socket body 1 is used, the rotary table 2 is rotated reversely, the locking block 10 is shifted to move reversely in the moving process of the first positioning block 3 on the rotary table 2, the upper sleeve 8 is finally driven to rotate reversely, because the rotating direction of the upper sleeve 8 is the same as the vertical face direction of the positioning wedge 15, under the action of the vertical face matched with the positioning wedge 15 and the first limiting groove 16, the upper sleeve 8 drives the lower sleeve 9 to rotate reversely together, because the driving pin 11 cannot rotate, the rotating effect of the lower sleeve 9 relative to the driving pin 11 is formed, so the driving pin 11 slides on the inclined face at the top of the vertical section 14 and enters the inclined section 13 again, then moves upwards along the inclined section 13 under the action of the spring 7 and finally enters the upper sliding groove 12, and at this time, the locking mechanism returns to the state shown in fig. 3 again, at this time, the first limiting block 3 returns to between the two locking blocks 10 again, the turntable 2 is locked.
