Embodiment 1

[0031] combined with Figure 1-3 , the present embodiment provides a synchronous door knife, including: a door knife base plate 1, the door knife base plate 1 is installed on the car door machine; a knife arm assembly, the knife arm assembly includes a first knife arm 2, a second knife arm Arm 3, first connecting rod 4 and second connecting rod 5, the middle part of described first connecting rod 4 and described second connecting rod 5 is hinged with described door knife base plate 1, and described first connecting rod 4 and all The two ends of the second connecting rod 5 are respectively hinged with the first knife arm 2 and the second knife arm 3, and the first knife arm 2, the second knife arm 3, the first connecting rod 4 and the second The connecting rods 5 together form a parallelogram mechanism with variable spacing, the minimum spacing L between the first knife arm 2 and the second knife arm 3 is greater than the diameter D of the door ball 19; the door knife transmiss...

Embodiment 2

[0035] Such as figure 1 As shown, the synchronous door knife of this embodiment, compared with the technical solution of embodiment 1, also includes a lock hook 13, and the lock hook 13 is hinged on the door knife bottom plate 1, and the lock hook 13 is fixed on the The locks on the car door machine cooperate to realize the locking and opening of the car door. The locking hook 13 is hinged on the door knife base plate 1 by a pin shaft, so that the locking hook 13 can rotate around the pin shaft. When the locking hook 13 rotates to a horizontal position, the locking hook 13 is hung on the lock piece on the car door machine. At this time, the car door is locked, so that the car door is blocked, and the door cannot be opened. After the lock hook 13 is lifted by rotation, the lock hook 13 breaks away from the lock on the car door machine. The compartment door moves in the horizontal direction to open.

Embodiment 3

[0037] combined with Figure 1-2 , the synchronous door knife of this embodiment, compared with the technical solution of embodiment 2, a compression spring 14 is also connected between the lock hook 13 and the door knife bottom plate 1, and the compression spring 14 is used to align the lock hook 13 Apply locked spring force. By setting the compression spring 14 to apply a locking elastic force to the locking hook 13, the locking hook 13 maintains a locking tendency.

[0038] Such as figure 1 and 2 As shown, in actual use, the lock hook 13 is also provided with a positioning pin 15, and the outer sleeve of the positioning pin 15 is a rubber sleeve; the door knife bottom plate 1 is provided with a limit hole 16, and the limit hole 16 The hole diameter is larger than the positioning pin 15, and the positioning pin 15 passes through the limiting hole 16. This setting can utilize the abutment of the positioning pin 15 and the limiting hole 16 to limit the up and down swing ra...

Abstract

The invention discloses a synchronous door vane and an elevator, and relates to the technical field of elevator equipment. The synchronous door vane comprises a door vane bottom plate, a vane arm assembly and a door vane transmission assembly, the vane arm assembly comprises a first vane arm, a second vane arm, a first connecting rod and a second connecting rod, and the first vane arm, the second vane arm, the first connecting rod and the second connecting rod jointly form a parallelogram mechanism with a variable interval; the minimum distance L between the first vane arm and the second vane arm is larger than the diameter D of a landing door ball; and the door vane transmission assembly is connected with the vane arm assembly, and the door vane transmission assembly is used for driving the vane arm assembly to rotate. The synchronous door vane can achieve small-amplitude superposition of original independent actions in the vertical direction and the horizontal direction of an elevator, and when the first vane arm and the second vane arm clamp the landing door ball, vertical up-down movement of the elevator can still be achieved, so that the elevator running time is saved, the elevator running efficiency is improved, waiting time is saved when passengers take the elevator, and the experience feeling of passengers taking the elevator is further improved.

Description

technical field [0001] The invention relates to the technical field of elevator equipment, in particular to a synchronous door knife and an elevator. Background technique [0002] As a vehicle for transporting passengers, the elevator has two modes of movement, namely, the vertical movement of the car and the horizontal movement of the door system. At present, most of the door knife components on the door operator device of the door system are synchronous door knife. The door knife on the device and the door lock on the landing door device are in a coupling relationship, that is, when the elevator door system opens the door, the door knife moves so that the left and right arms of the door knife clamp the gate ball on the door lock before the door can be opened. ; and when the elevator needs to move vertically to the designated floor, the door knife is also moved first so that the left and right knife arms of the door knife are separated from the gate ball before the ladder ...
