Description
Technical field
The step that the utility model relates to a kind of staircase fender guard, the particularly a kind of staircase fender guard that subsides.
Background technology
The step of the existing escalator fender guard that subsides is provided with limit switch below terraced pole plate; when the stepboard of escalator breaks down when subsiding; the action of triggering limit switch, limit switch makes the staircase auto-stop by control circuit, enlarges to prevent fault.Fender guard breaks down and can protect though existing step subsides, because limit switch is installed in the stepboard below, inconvenience resets behind trouble removal.
The utility model content
The purpose of this utility model is, a kind of step of the staircase fender guard that subsides is provided, behind trouble removal so that reset.
The technical solution of the utility model: a kind of step of staircase fender guard that subsides; comprise adapter plate that is located at fishback one side and the lever that is located at the stepboard below; lever middle part via pins is hinged on the adapter plate; lever one end is positioned at the stepboard below; the lever other end is provided with limit switch, and the contact of limit switch is positioned at the lever top.
Compared with prior art; the utility model is that lever is set below stepboard; lever middle part via pins is hinged on the adapter plate, and lever one end is positioned at the stepboard below, when stepboard subsides; to depress lever; the other end of lever is upturned, withstands the contact on the limit switch that is installed in the lever other end, make the limit switch action; limit switch cuts off the staircase power supply by control circuit, plays a protective role.The utility model is that the limit switch that will be installed in the stepboard below at present moves to fishback one side, so that the staff can directly reset outside behind the trouble removal.This device is simple and practical, easy to use, transforms easily, and cost is low.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Being labeled as in the accompanying drawing: 1-fishback, 2-adapter plate, 3-stepboard, 4-lever, 5-pin, 6-limit switch, 7-contact.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment.A kind of step of staircase fender guard that subsides, as shown in Figure 1, it is that limit switch originally is mounted in stepboard 3 belows to the subside improvement of fender guard of original step, inconvenience resets behind the trouble removal.This example is in fishback 1 one sides adapter plate 2 to be set, limit switch 6 is installed on the adapter plate 2, via pins 5 hinged levers 4 on adapter plate 2, and an end of lever 4 reaches stepboard 3 belows, lever 4 other ends are provided with a limit switch 6, and the contact 7 of limit switch 6 is positioned at the top of lever 4 ends.When stepboard 3 subsided, stepboard 3 was pressed in lever 4 one ends that reach stepboard 3 belows, the other end meeting perk of lever 4; withstand the contact 7 of limit switch 6, make limit switch 6 actions, limit switch 6 cuts off the staircase power supply by control circuit; the staircase auto-stop plays a protective role.Because limit switch 6 is located at fishback 1 one sides, institute is so that carry out reset operation.
Concrete structure as shown in Figure 1, comprise adapter plate 2 that is located at fishback 1 one sides and the lever 4 that is located at stepboard 3 belows, lever 4 middle part via pins 5 are hinged on the adapter plate 2, lever 4 one ends are positioned at stepboard 3 belows, lever 4 other ends are provided with limit switch 6, and the contact 7 of limit switch 6 is positioned at lever 4 tops.
Claims (1)
1. the step of the staircase fender guard that subsides; it is characterized in that: comprise the adapter plate (2) that is located at fishback (1) one side and be located at the lever (4) of stepboard (3) below; lever (4) middle part via pins (5) is hinged on the adapter plate (2); lever (4) one ends are positioned at stepboard (3) below; lever (4) other end is provided with limit switch (6), and the contact (7) of limit switch (6) is positioned at lever (4) top.
