Preferably, the inner side of the protective shell is provided with an arc-shaped groove for accommodating the roller.

Preferably, the rollers are respectively provided at positions corresponding to the ends of the handrail belt and the middle of the upper surface inside the protective case.

Preferably, the protective shell is a rubber shell.

Preferably, the clearance between the protective shell and the hand strap is 3-4 mm.

Preferably, the length of the protective shell sleeved on the handrail belt is 120 mm.

Preferably, the protection devices are four groups and are respectively arranged at the turning positions of the handrail belts at the two sides of the entrance and the exit of the escalator.

Compared with the prior art, the utility model has the beneficial effects that:

according to the utility model, the protective shell is arranged on the handrail belt and is connected with the protective shell through the spring fixed on the handrail device, and the protective shell drives the spring to deform when deforming so as to enable the protective shell to contact the electrical switch to turn off the power supply of the elevator, so that the device is sensitive in action; the device is connected with the elevator power supply control circuit through the electric switch, so that the elevator power supply is quickly controlled to be disconnected, and a protection effect is achieved; meanwhile, the gap between the protective shell and the hand strap is small, so that fingers are not easy to clamp, and the elevator accident caused by insensitivity of the protective device is effectively prevented.

fig. 2 is a transverse cross-sectional view of the novel escalator handrail belt inlet protection device.

Detailed Description

In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the handrail belt 5 of the escalator is sleeved on the handrail device 6 and runs up and down along the handrail device 6, and the handrail belt entrance protecting devices of the escalator have four groups, are respectively arranged at the turning positions of the handrail belts at two sides of the entrance and exit of the escalator, and mainly comprise a protecting shell 1, an electric switch 2, a spring 3 and a roller 4. Protective housing 1 is for having the rubber shell of certain hardness, and one end is laminated with handrail 5's shape, and the other end is equipped with the chimb, and protective housing 1 overlaps on handrail 5, and the bottom compresses tightly with handrail device 6's both sides face contact, and the bottom of chimb is connected fixedly through spring 3 and handrail device 6, and spring 3 has two sets ofly, installs respectively in handrail device 6's the left and right sides.

The inner side surface of the protective shell 1 is provided with arc-shaped grooves 8 for accommodating the rollers 4, and the rollers 4 are provided with a plurality of groups and are respectively arranged at the corresponding positions in the middle of the inner side of the protective shell 1 and the end part and the upper surface of the handrail 5.
