Embodiment
The structural principle and operation principle of the present invention are described in detail below in conjunction with the accompanying drawings：As shown in Figures 1 to 3, originally
Invent a kind of toe guard of elevator car of automatic controlled height, including parallel fixation backplate 1 and sliding shelling plate 2, the fixed both sides of backplate 1
Provided with vertical guide plate 3, sliding shelling plate 2 is embedded in guide plate 3；Guide plate 3 includes bottom plate 4 and pressing plate 5, the inner side of bottom plate 4 with
The fixed outside of backplate 1 is fixedly connected, and the outside of bottom plate 5 is fixedly connected with the outside of pressing plate 4, and guide groove 6 is provided between bottom plate and pressing plate,
The middle part of bottom plate 4 is additionally provided with the first vertical groove, and pressing plate 5 is provided with the second vertical groove accordingly, and the both sides of sliding shelling plate 2 are provided with
L-shaped flanging 21, L-shaped flanging 21 are embedded in the first groove 41, and the first ball 42 is provided between the groove 41 of L-shaped flanging 21 and first,
The second ball 52 is provided with second groove 51, the sliding shelling plate 2 of L-shaped flanging 21 can slide up and down in guide groove 6.
The L-shaped flanging 21 of the both sides of sliding shelling plate 2, on the one hand with the first ball 42 in guide groove 6 and the second ball 52
Coordinate, effectively control the active strokes of sliding shelling plate 2；On the other hand coordinate with the first ball 41, effectively limit sliding shelling plate 2
Move left and right, avoid sliding shelling plate 2 and the side sliding friction of guide groove 6 and produce noise；It is furnished with ball in guide groove 6, may be used also
To reduce the frictional force and noise when sliding shelling plate 2 moves up and down.
Guide groove 6 also enhances the intensity of sliding shelling plate 2, can preferably realize the function of its security protection.
Spacer 7 is provided between bottom plate 4 and pressing plate 5, the size of guide groove 6 can be adjusted by spacer 7, to adapt to not
The sliding shelling plate 2 of stack pile, while the gap between the first ball 42 and the second ball 51 can also be adjusted, ensure sliding shelling plate
2 activity it is unobstructed.
First groove 41 and the both ends of the second groove 51 are designed with ball baffle plate（It is not drawn into figure）, prevent the He of the first ball 42
Second ball 51 comes off.
The bottom of sliding shelling plate 2 is provided with flanging 22.Sliding shelling plate 2 is set to play a cushioning effect when touching pit ground,
Sliding shelling plate 2 can preferably be protected.
Pressing plate inside lower end is provided with block 8, and the upper end of sliding shelling plate 2 is provided with boss 9 corresponding to block 8.Prevent sliding shelling plate 2
It is separated from guide groove 6.
Embodiment is as follows：
As shown in figure 4, after the toe guard of elevator car of the automatic controlled height installs, when elevator pit depth is insufficient or shallow pit
When, car runs to bottom, sliding shelling plate 2 and contacts pit ground, sliding by the automatic contraction upwards of sliding shelling plate after resistance 2
Dynamic backplate 2 is overlapping with fixed backplate 1, and the overall effective vertical range of toeguard reduces, and avoids toeguard and hits pit ground
Cause the risk of device damage.
If the situation at crouching bottom occurs in elevator, during compression buffer, sliding shelling plate 2 also continues to be compressed car,
When buffer is compressed complete, sliding shelling plate 2 also levels off to complete contraction.
When elevator travels away from pit, sliding shelling plate 2 is automatic to slide downwards in the presence of by gravity itself, now solid
The effective vertical height of vertical component for determining backplate 1 and sliding shelling plate 2 is not less than 750mm.
Sliding shelling plate 2 leaves pit region, is extended automatically using own wt, reaches the security protection work(of elevator requirement
Can, and after sliding shelling plate 2 is less than first floor entrance height, without its safeguard function, now then start to shrink automatically, it is anti-to meet
The only safety requirements of pit extruding.
Certainly, the present invention can also have other various embodiments, ripe in the case of without departing substantially from spirit of the invention and its essence
Know those skilled in the art when can be made according to the present invention it is various it is corresponding change and deformation, but these corresponding change and become
Shape should all belong to the protection domain of appended claims of the invention.
