Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0025] Refer to Figures 1 - 7, an embodiment provided by the present utility model: a reinforced elevator toe guard, including a toe guard body 1, a first fixing rod 2 is fixedly connected to the toe guard body 1, a first chute 3 is provided on the first fixing rod 2, a first rack 4 is slidably connected to the first chute 3, one end of the first rack 4 is fixedly connected to a first foot pad 5, a second fixing rod 6 is fixedly connected to the toe guard body 1, a second chute 7 is provided on the second fixing rod 6, a second rack 8 is slidably connected to the second chute 7, one end of the second rack 8 is fixedly connected to a second foot pad 9, a groove 10 is provided on the toe guard body 1, a third chute 11 is provided on the toe guard body 1, a fourth chute 12 is provided on the toe guard body 1, a cylinder 13 is rotatably connected to the toe guard body 1, a circular gear 14 is fixedly connected to one end of the cylinder 13, the circular gear 14 is meshed with the first rack 4, the circular gear 14 is meshed with the second rack 8, a wedge block 15 is slidably connected to the third chute 11, one end of the wedge block 15 is fixedly connected to a spring 16, one end of the spring 16 is fixedly connected to the toe guard body 1, a connecting rod 17 is fixedly connected to the wedge block 15, the connecting rod 17 is slidably connected to the fourth chute 12, a locking tooth 18 is fixedly connected to the connecting rod 17, the locking tooth 18 is meshed with the circular gear 14. When using the reinforced elevator toe guard, by rotating the cylinder 13 with a hex wrench, the positions of the first foot pad 5 and the second foot pad 9 on the inner wall of the hoistway can be quickly adjusted, so as to flexibly adjust the supporting position of the toe guard body 1, enabling the staff to adjust the most suitable maintenance space according to needs, and improving the flexibility and comfort of the maintenance operation.
[0026] A transverse reinforcing rod 19 is fixedly connected to one side of the toe guard body 1, a vertical reinforcing rod 20 is fixedly connected to one side of the toe guard body 1, a bottom plate 21 is provided at the bottom of the toe guard body 1, a fixing plate 22 is fixedly connected to the toe guard body 1, a connecting hole 23 is provided on the fixing plate 22, the first foot pad 5 and the second foot pad 9 are respectively arranged on the sides of the first rack 4 and the second rack 8 in opposite directions, the fourth chute 12 is communicated with the third chute 11, the groove 10 is communicated with the third chute 11, the spring 16 is arranged in the third chute 11, one end of the wedge block 15 is arranged in the groove 10, there are several groups of transverse reinforcing rods 19, there are several groups of vertical reinforcing rods 20, and the transverse reinforcing rods 19 and the vertical reinforcing rods 20 are arranged in a cross pattern. When using the reinforced elevator toe guard, through the cross layout of the transverse reinforcing rod 19 and the vertical reinforcing rod 20 provided on the toe guard body 1, the overall structural strength of the toe guard body 1 is significantly enhanced, enabling the toe guard to withstand greater weight and pressure, effectively preventing deformation or damage caused by elevator overload or other external factors, thereby extending the service life of the toe guard and improving the safety of elevator operation.
[0027] Working principle: When using the reinforced elevator toe guard, the staff first installs the toe guard body 1 at the bottom of the car with bolts through the connection holes 23 on the fixing plate 22. The cross - setting of several groups of horizontal reinforcing bars 19 and several groups of vertical reinforcing bars 20 on the toe guard body 1 strengthens the toe guard body 1. The addition of the horizontal reinforcing bars 19 and the vertical reinforcing bars 20 makes the overall structure of the toe guard body 1 more stable, capable of withstanding greater weight and pressure, effectively preventing deformation or damage caused by overloading or other external factors. When maintenance is required at the bottom of the car, the staff inserts a hexagonal wrench into the hexagonal groove 10 on the cylinder 13. When the hexagonal wrench is inserted, it drives the wedge - shaped block 15 to slide into the third chute 11 and simultaneously compresses the third chute 11. At the same time, the wedge - shaped block 15 drives the connecting rod 17 to slide on the fourth chute 12, and the connecting rod 17 drives the tooth 18 to disengage from the meshing with the circular gear 14. When the hexagonal wrench is engaged into the hexagonal groove 10 on the cylinder 13, the hexagonal wrench is turned. The hexagonal wrench drives the cylinder 13 to rotate on the toe guard body 1, and the cylinder 13 drives the circular gear 14 to rotate. The circular gear 14 simultaneously drives the first rack 4 and the second rack 8 to slide in opposite directions on the first chute 3 and the second chute 7. When the foot pad 1 5 at one end of the first rack 4 and the foot pad 2 9 at one end of the second rack 8 are in contact with the inner wall of the hoistway, they support the toe guard body 1. Then the staff unscrews the bolts connected to the connection holes 23 from the car, and then slightly turns the cylinder 13 in the reverse direction with the hexagonal wrench so that the foot pad 1 5 and the foot pad 2 9 slide downward while being in contact with the hoistway. When the toe guard body 1 moves to a space where the staff can conveniently maintain the car, the hexagonal wrench is turned in the reverse direction to make the foot pad 1 5 and the foot pad 2 9 closely fit against the inner wall of the hoistway to fixedly support the toe guard body 1. Thus, there is no need to separately retain bolts to support the toe guard body 1, and the staff can adjust a suitable maintenance space as required, which not only improves the comfort of the staff during maintenance but also improves the maintenance efficiency of the car.
[0028] Finally, it should be noted that the above - mentioned are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
