Embodiment 1

[0028] Such as Figure 1~4 As shown, a foldable car toe guard includes a first toe guard 107 fixed to the car platform, a second toe guard 108 hinged with the first toe guard 107 through a main hinge 109, and a second toe guard 108 fixed to the car bed platform. A fixing frame 101, a second fixing frame 102 fixed on the second toe guard 107, and a link mechanism are also included.

[0029] Wherein, the link mechanism includes: the first base 103 connected on the first fixed frame 101, the first connecting rod 105 hinged on the first base 103, the second base 104 connected on the second fixed frame 102, the second base 104 hinged on the The second connecting rod 106 of the second base 104 and the air spring 110 whose two ends are respectively hinged to the first connecting rod 105 and the first toe guard 107 . The first connecting rod 105 and the second connecting rod 106 are connected by a bearing 112, and the bearing 112 can also be replaced by a pin or a hinge. The second ...

Embodiment 2

[0038] refer to Figure 7 and Figure 8As shown, it is another embodiment of the present invention. The difference between this embodiment and Embodiment 1 is that the air spring 110 in Embodiment 1 is replaced by a compression spring, and the compression spring includes a screw rod 301 and a spring 302. To the same effect as the air spring 110. When the elevator needs maintenance, the triangular lock 201 is rotated, and the second toe guard 108 is fully expanded under the drive of the compression spring. At the same time, the compression spring can strengthen the stability of the foldable toe guard when the elevator is running, prevent the foldable toe guard from shaking, and reduce noise.

Abstract

The invention discloses a foldable car foot guard board. The foldable car toe guard comprises a first toe guard body, a second toe guard body, a foldable connecting rod mechanism and a locking mechanism, wherein the first toe guard body is fixed to a car bottom platform, the second toe guard body is hinged to the first toe guard body, and the locking mechanism is used for fixing the two folded toeguard bodies. The connecting rod mechanism comprises a first connecting rod and a second connecting rod, wherein the first connecting rod is movably connected to the bottom of the car bottom platform, the second connecting rod is movably connected to the second toe guard body, the first connecting rod is movably connected with the second connecting rod, and the connecting part between the first connecting rod and the second connecting rod is provided with a limiting device for limiting the reverse folding of the first protecting plate and the second protecting plate; and elastic supports forsupporting the two folded toe guard bodies are arranged between the first connecting rod and the first toe guard body. The foldable car toe guard is suitable for a shallow bottom pit well, high in strength and not prone to damage, effectively solves the problem that a maintainer or a passenger falls into the well, meanwhile meets the requirements of related standards, and improves the safety of anelevator.

Description

technical field [0001] The present invention relates to an elevator car, in particular to a foldable car toe guard for an elevator car. Background technique [0002] At present, to install an elevator in an existing building, it is necessary to excavate the elevator pit separately, but there are often many water pipes and wires around the existing building, and the excavation of a deeper pit requires additional modification of the water pipes and wires, which is costly. Therefore, the installation of ladders generally adopts a shallow pit well structure. [0003] In order to adapt to the shallow pit shaft, the invention patent document with the publication number CN103896142A discloses a rotatable car toe guard, which can be folded by the rotation of the torsion spring, but the strength of this structure is poor when it is fully unfolded. It will become a folded state when the force is applied, and the function of the toe guard cannot be realized; in the invention patent do...
