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...
