detailed description

Embodiments of the utility model will be described in further detail below in conjunction with the accompanying drawings.

Referring to FIGS. 1-3 , the embodiment of the present utility model provides a safety lock cylinder with a knob, which includes a lock cylinder housing 1 , a lock cylinder inner core 2 , a cylindrical part 3 and a connector assembly 5 .

The lock cylinder housing 1 is provided with a dial 11 and a knob, and the dial 11 is provided with a connection notch. When the knob rotates, it can drive the dial 11 to rotate, thereby changing the direction of the connection notch.

The lock cylinder inner core 2 is provided with a keyhole, and the lock cylinder inner core 2 is accommodated in the lock cylinder housing 1, and the key insertion end of the lock cylinder inner core 2 is provided with a first row of pinholes for the lock cylinder inner core, and the first row of lock cylinders The pinholes of the inner core are provided with anti-drill number bullets 16 and anti-drill I-shaped bullets 17. The columnar component 3 is disposed opposite to the inner core of the lock cylinder, and the columnar component 3 is provided with a receiving hole 4 .

Also referring to FIG. 5 , the connector assembly 5 is disposed at the end of the keyhole and partially accommodated in the receiving hole 4 , which includes a connector 6 , a push rod 8 , a connector spring 9 and a connector block 12 . The connecting piece 6 is provided with connecting ribs and holes 7, wherein the holes 7 are stepped holes. The connecting rib matches the connecting notch on the dial 11, and when the connector assembly rotates, the dial can be driven to rotate, and the push rod 8 passes through the stepped hole. The connecting member spring 9 is sheathed on the push rod 8 , and its two ends respectively bear against the end of the push rod 8 close to the key hole and the step surface of the stepped hole. And the connector block 12 is fixed on the front end of the connector 6 . A lock cylinder spring 10 is also provided in the receiving hole 4 , and the lock cylinder spring 10 is sheathed on the push rod 8 , and its two ends respectively abut against the connector assembly 5 and the bottom of the receiving hole 4 . After the key is inserted into the inner core 2 of the lock cylinder, the connector assembly 5 will be pushed to move forward. When the connecting rib is aligned with the connecting notch, the lock cylinder spring 10 will be pressed; when the connecting rib is not aligned with the connecting notch, the connecting member spring will 9 is under pressure, wherein the elastic coefficient of the connector spring 9 is three times or more than three times that of the lock cylinder spring 10 .

Referring to Fig. 1 and Fig. 2, the key insertion end of the lock cylinder housing 1 is also provided with a first row of lock cylinder housing pinholes 13 and a second row of lock cylinder housing pinholes 14. Two anti-drilling pins 15 are arranged between the pinholes 13 and the pinholes 14 of the second row of lock cylinder housings to play the role of anti-drilling.

As shown in FIG. 4 , the inner core 2 of the lock cylinder is also provided with an anti-drilling, anti-pulling and anti-pull steel sheet 18 .

When the door is locked inside, the knob rotates and drives the dial 11 to rotate, and the dial 11 rotates so that the connecting notch on the dial 11 is not aligned with the connecting rib on the connector 6. When the key is inserted back into the lock cylinder, the key will Unable to push the connector assembly 5 into the dial 11, the connector spring 9 will be pushed when the key is inserted, and the rotation of the lock cylinder inner core 2 will drive the connector assembly 5 to rotate, and the dial 11 does not rotate at this time. When the connecting rib on the connector 6 is rotated to be aligned with the connection notch of the dial 11, the connector assembly 5 will enter the dial 11, thereby restoring the connection effect, realizing the anti-locking of the door, and the purpose of opening the door with a key outside.

When opening the door with a steel wire, because the elastic coefficient of the connecting piece spring 9 is three times or more than three times that of the lock cylinder spring 10, when the connecting piece assembly 5 is pushed, the lock cylinder spring 10 is pushed, and the connecting piece Spring 9 does not move, and causes steel wire to be unable to enter in the connector assembly 5, just can't rotate connector 6, thereby has played anti-steel wire opening effect, has improved antitheft ability.

Adopting the safety lock cylinder with knob in the utility model can realize the purpose of anti-locking inside the door and opening the door with a key outside, which will be more convenient in daily life, and can prevent steel wire from opening at the same time, greatly improving the anti-theft ability.

The utility model is not only limited to the above-mentioned best implementation mode, anyone can draw other various forms of products under the enlightenment of the utility model, but no matter make any changes in its shape or structure, anyone who has the same features as the utility model The same or similar technical solutions are all within the scope of protection.
