[0025] This specific implementation is a smart door and window locking worm mechanism, and its structural diagram is as follows Figure 1-Figure 6As shown, the worm mechanism includes a door lock device box 1, one end of the door lock device box 1 is slidably connected with a rectangular lock block 2, the other end of the door lock device box 1 is provided with a vertical worm gear 6, the inside of the door lock device box 1 is slidably connected with a circular knob 3, one side of the circular knob 3 is fixed with a longitudinal sliding column 12, the outer side of the longitudinal sliding column 12 is slidably connected with a longitudinal lifting column 11, the outer side of the longitudinal lifting column 11 is fixed with a longitudinal worm 10, and the inside of the door lock device box 1 is provided with a lifting mechanism for lifting the longitudinal worm 10.
[0026] Among them, an arc-shaped fixing block 4 is fixed to the bottom end of the door lock device box 1, and a driving motor 5 is fixed to one end of the arc-shaped fixing block 4 by bolts. The output end of the driving motor 5 passes through the outer side of the vertical worm gear 6 and is fixedly connected to the vertical worm gear 6. A transverse threaded rod 7 is fixed to the output end of the driving motor 5. A transverse circular column 9 is threadedly connected to the outer side of the transverse threaded rod 7. An arc-shaped supporting plate 8 is slidably connected to the outer side of the transverse circular column 9. The bottom of the arc-shaped supporting plate 8 is fixedly connected to the door lock device box 1, and the transverse circular column 9 is close to one end of the rectangular lock block 2 and is fixedly connected to the rectangular lock block 2;
[0027] A plurality of transverse rectangular sliders are fixed to the outside of the transverse circular column 9, and a transverse rectangular slide groove adapted to the transverse rectangular slider is provided inside the arc-shaped support plate 8. The transverse circular column 9 and the arc-shaped support plate 8 are slidably connected by the transverse rectangular slider and the transverse rectangular slide groove. The transverse circular column 9 can slide inside the arc-shaped support plate 8 by setting the transverse rectangular slider and the transverse rectangular slide groove.
[0028] Here, the operation of the driving motor 5 enables the vertical worm gear 6 and the transverse threaded rod 7 to rotate, and the rotation of the transverse threaded rod 7 enables the transverse circular column 9 to slide on the outside of the arc-shaped support plate 8, thereby enabling the rectangular lock block 2 to move into the door lock device box 1, thereby releasing the restriction of the rectangular lock block 2 on the door and window;
[0029] In addition, the lifting mechanism includes a vertical component, the outer side of one end of the circular knob 3 is sleeved with the vertical component, one end of the vertical component is provided with a vertical rotating column 14, the bottom of the vertical rotating column 14 is rotatably connected with a circular collar 13 through a pin, and the circular collar 13 is sleeved on the outer side of the longitudinal lifting column 11 and is rotatably connected with the longitudinal lifting column 11 through a bearing;
[0030] The vertical assembly includes a longitudinal sliding plate 15, one end of the longitudinal sliding plate 15 is rotatably connected to the vertical rotating column 14 via a pin shaft, a vertical sliding column 21 is fixed to the bottom of the longitudinal sliding plate 15, and a vertical support plate 20 is slidably connected to the outer side of the bottom of the vertical sliding column 21, and the vertical support plate 20 is sleeved on the outer side of the circular knob 3 and is rotatably connected to the circular knob 3 via a bearing, so that the vertical sliding column 21 can be vertically lifted and lowered inside the vertical support plate 20, and the rotation of the circular knob 3 can drive the longitudinal sliding column 12 to rotate, so that the circular knob 3 can rotate inside the vertical support plate 20;
[0031] The longitudinal sliding plate 15 is internally slidably connected with a longitudinal light rod 16, the longitudinal light rod 16 is close to one end of the door lock device box 1 and is fixedly connected to the door lock device box 1, and an arc block is fixedly connected to the door lock device box 1 at the other end of the longitudinal light rod 16, and a rigid spring 17 is arranged between the arc block and the longitudinal sliding plate 15 and on the outside of the longitudinal light rod 16, so that the longitudinal sliding plate 15 can slide on the outside of the longitudinal light rod 16, and the sliding of the longitudinal sliding plate 15 causes the rigid spring 17 to be deformed by force;
[0032] One end of the outer side of the longitudinal lifting column 11 is rotatably connected to a vertical sliding rod 19 through a bearing, and the outer side of the vertical sliding rod 19 is slidably connected to a vertical circular column 18. The top of the vertical circular column 18 is fixedly connected to the door lock device box 1, so that when the longitudinal worm gear 10 is lifted or lowered, the vertical sliding rod 19 can slide vertically on the outer side of the vertical circular column 18. Through the arrangement of the vertical sliding rod 19 and the vertical circular column 18, the lifting and lowering trajectory of the longitudinal worm gear 10 can be limited.
[0033] Here, when the driving motor 5 cannot operate, the circular knob 3 is pressed, and the pressing of the circular knob 3 enables the longitudinal sliding plate 15 to slide on the outside of the longitudinal light rod 16, thereby causing the rigid spring 17 to contract under force, and the movement of the longitudinal sliding plate 15 passes through the vertical rotating column 14 and the longitudinal sliding column 12, so that the longitudinal lifting column 11 can be vertically lowered, thereby causing the vertical sliding rod 19 to slide vertically on the outside of the vertical sliding rod 19. In this process, the vertical sliding column 21 can slide vertically inside the vertical support plate 20, so that the circular knob 3 can be lowered while moving close to the longitudinal worm 10, and the longitudinal sliding column 12 can slide inside the longitudinal lifting column 11. When the longitudinal worm 10 is engaged with the vertical worm wheel 6, the circular knob 3 is rotated so that the circular knob 3 can rotate inside the vertical support plate 20. The rotation of the circular knob 3 drives the longitudinal sliding column 12 so that the longitudinal lifting column 11 and the longitudinal worm 10 can rotate. The rotation of the longitudinal worm 10 enables the vertical worm wheel 6 to rotate, thereby enabling the rectangular lock block 2 to move inside the door lock device box 1.
[0034] Working principle: When the worm mechanism of the present technical solution is used, the operation of the driving motor 5 enables the vertical worm wheel 6 and the transverse threaded rod 7 to rotate, and the rotation of the transverse threaded rod 7 enables the transverse circular column 9 to slide on the outside of the arc-shaped support plate 8, thereby enabling the rectangular lock block 2 to move into the door lock device box 1, thereby releasing the restriction of the rectangular lock block 2 on the door and window;
[0035] When the driving motor 5 cannot operate, the circular knob 3 is pressed, and the pressing of the circular knob 3 enables the longitudinal sliding plate 15 to slide on the outside of the longitudinal light rod 16, thereby causing the rigid spring 17 to contract under force, and the movement of the longitudinal sliding plate 15 passes through the vertical rotating column 14 and the longitudinal sliding column 12, so that the longitudinal lifting column 11 can be vertically lowered, thereby allowing the vertical sliding rod 19 to slide vertically on the outside of the vertical sliding rod 19. In this process, the vertical sliding column 21 can slide vertically inside the vertical support plate 20, so that the circular knob 3 It can be lowered while moving close to the longitudinal worm 10, and the longitudinal sliding column 12 can slide inside the longitudinal lifting column 11. When the longitudinal worm 10 is engaged with the vertical worm wheel 6, the circular knob 3 is rotated so that the circular knob 3 can rotate inside the vertical support plate 20. The rotation of the circular knob 3 drives the longitudinal sliding column 12 to rotate the longitudinal lifting column 11 and the longitudinal worm 10. The rotation of the longitudinal worm 10 allows the vertical worm wheel 6 to rotate, thereby allowing the rectangular lock block 2 to move inside the door lock device box 1.
[0036] All technical features in this embodiment can be freely combined according to actual needs.
[0037] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
