Abstract
The invention discloses an embedding structure of the rear border and a kickplate of an escalator step. The embedding structure comprises the kickplate and the rear border which has the lower end embedded with the upper end of the kickplate; the surface of the kickplate is evenly provided with a plurality of kickplate convex teeth in parallel; the rear side of the rear border is provided with rear convex teeth corresponding to the kickplate convex teeth; the outer side surface of kickplate convex teeth is provided with a kickplate groove; the lower part of the rear convex tooth is provided with a rear border groove; the lower end of the rear border groove has the same shape as the kickplate groove and is butted with the kickplate groove; and the rear border groove is gradually transited to the surface on the upper part of the rear convex teeth upward from the lower end of the groove. The embedding structure has the advantages that the embedding structure can improve a gap between adjacent steps during the operation of an escalator, particularly the operation from an inclined section to an horizontal section, prevent clothes and objects from being clamped, improve the safety of the operation of the escalator, and effectively strengthen the rigidity of the kickplate at the same time.
Description
Technical field
The present invention relates to behind a kind of escalator step border and kickplate edge and close structure.
Background technology
Escalator is that public places such as market, airport transport one of main transportation device of passenger at floor gap.During escalator operation, step is a main motion parts, prevents between adjacent step that clothing, thing clamping stagnation from being important safety measure.By changing the profile of tooth of step riser, the gap when improving the adjacent step operation, the safety when improving escalator operation.Patent announcement CN2573463 " bayonet-type corrosion-resistant steel step ": propose by between pedal and kickplate, setting up a side set attaching parts, realize that staircase is meshed with the trailing edge of adjacent step in its leading edge of step of horizontal segment operation up and down.Patent CN3297318 " delimits behind the escalator step pedal ": delimit after having expressed a kind of and side set that kickplate engages.Patent CN3486168 " escalator step kickplate ": the kickplate flute profile of having expressed a kind of rectilinear form.Above technology, the flute profile that does not all relate to the border, back is consistent with the kickplate flute profile, and edge closes connection, adjacent step gap when not improving staircase oblique line section in service to horizontal segment.
Summary of the invention
The object of the invention provides behind a kind of escalator step border and kickplate edge and closes structure, when it can improve escalator operation especially by the gap of tilting section adjacent step when horizontal segment moves, prevent the clamping stagnation of clothing, thing, improve the safety of escalator operation; Kickplate rigidity has also obtained strengthening effectively simultaneously.
Technical scheme of the present invention is: border and kickplate edge closes structure behind a kind of escalator step, comprise the back border that kickplate and lower end and kickplate upper end edge closes, described kickplate surface evenly is provided with some kickplate double wedges that are parallel to each other, border, described back rear side is provided with and the cooresponding back of kickplate double wedge double wedge, described kickplate double wedge lateral surface is provided with the kickplate groove, double wedge bottom, described back is provided with the back boundary groove, described boundary groove lower end, back and corresponding joint consistent with the kickplate groove shapes, back boundary groove is upwards carried out the transition to the plane on double wedge top, back gradually by the lower end.
The further technical scheme of the present invention is: border and kickplate edge closes structure behind a kind of escalator step, comprise the back border that kickplate and lower end and kickplate upper end edge closes, described kickplate surface evenly is provided with some kickplate double wedges that are parallel to each other, border, described back rear side is provided with and the cooresponding back of kickplate double wedge double wedge, described kickplate double wedge lateral surface is provided with the kickplate groove, double wedge bottom, described back is provided with the back boundary groove, described boundary groove lower end, back and corresponding joint consistent with the kickplate groove shapes, back boundary groove is upwards carried out the transition to the plane on double wedge top, back gradually by the lower end.
At the bottom of the described kickplate groove crosscut pit is straight line, is connected by circumscribed two sections circular arcs that join between the side of bottom land and kickplate double wedge, and described circular arc one end is connected with the side of kickplate double wedge is tangent, the other end and tangent connection of bottom land one end.
The back double wedge lower end on border, described back is provided with downward positioning boss, and described positioning boss cooperation is embedded in kickplate double wedge inboard.
Advantage of the present invention is:
1. the present invention's corresponding groove on the kickplate double wedge of setting and kickplate on the back double wedge on border, back can be improved the gap of escalator by tilting section adjacent step when horizontal segment moves, and prevents the clamping stagnation of clothing, thing, improves the safety of escalator operation.
2. the shape of kickplate groove of the present invention is compared with general linear groove, can strengthen kickplate rigidity effectively.

The specific embodiment
Below in conjunction with drawings and Examples the present invention is further described:
Embodiment: extremely shown in Figure 6 as Fig. 1, border and kickplate edge closes structure behind a kind of escalator step, comprise the back border 2 that kickplate 1 and lower end and kickplate 1 upper end edge closes, described kickplate 1 surface evenly is provided with some kickplate double wedges 3 that are parallel to each other, border, described back 2 rear sides are provided with and kickplate double wedge 3 cooresponding back double wedges 4, the shape of double wedge 4 lower ends, described back and the consistent and corresponding joint of shape of kickplate double wedge 3.Described kickplate double wedge 3 lateral surfaces are provided with kickplate groove 5, double wedge 4 bottoms, described back are provided with back boundary groove 6, described boundary groove 6 lower ends, back and corresponding joint consistent with kickplate groove 5 shapes, back boundary groove 6 is upwards carried out the transition to the plane 13 on double wedge 4 tops, back gradually by the lower end.
7 is straight line at the bottom of the described kickplate groove 5 crosscut pits, is connected by circumscribed two sections circular arcs 8 that join between the side of bottom land 7 and kickplate double wedge 3, and described circular arc 8 one ends are connected with the side of kickplate double wedge 3 is tangent, the other end and tangent connection of bottom land 7 one ends.Such structure has improved the rigidity of kickplate, makes it more firm.
