DETAILED DESCRIPTION

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1 and Figure 2 The present invention provides a technical solution: an elevator floor door lock with adjustable oblique travel angle, comprising a hanging upper sill plate 1, in which an active door slide 3 and a passive door slide 4 are symmetrically arranged through a door guide rail 2, the active door slide 3 and the passive door slide 4 are connected through a linkage wire rope 5, and the linkage wire rope 5 ensures that the active door slide 3 and the passive door slide 4 move simultaneously, and a floor door lock mechanism 6 is arranged on the top of the active door slide 3 and the passive door slide 4, and a door knife 7 is inserted in the floor door lock mechanism 6.

[0014] The layer door lock mechanism 6 includes a door lock plate 6-1 and a mounting frame 6-2. The door lock plate 6-1 is fixedly mounted on the top of the passive door slide 4. The mounting frame 6-2 is rotatably connected to the top of the active door slide 3 through the first rotating shaft 6-3. The mounting frame 6-2 is rotatably connected to the adjusting plate 6-4 through the first rotating shaft 6-3. The left end of the mounting frame 6-2 is fixedly mounted with a lock hook 6-6 through a fixing bolt 6-5. A positioning mechanism 8 is installed between the adjusting plate 6-4 and the mounting frame 6-2. The front side wall of the adjusting plate 6-4 is equipped with two door balls 6-7. A door knife 7 is inserted between the two door balls 6-7. The two door balls 6-7 are fitted with the door knife 7. The door knife 7 is the door knife of the elevator car door. The opening and closing of the door knife 7 drives the mounting frame 6-2 to rotate around the first rotating shaft 6-3, so that the lock hook 6-6 and the door lock plate 6-1 are locked and opened.

[0015] The positioning mechanism 8 includes an arc-shaped adjustment hole 8-1 opened on the side wall of the adjustment plate 6-4. There are four arc-shaped adjustment holes 8-1, which are evenly distributed with the first rotating shaft 6-3 as the center. The four arc-shaped adjustment holes 8-1 are all screwed with a first positioning bolt 8-2 that penetrates into the mounting frame 6-2. The position of the adjustment plate 6-4 can be fixed by the first positioning bolt 8-2. The adjustment plate 6-4 can be rotated around the first rotating shaft 6-3 through the arc-shaped adjustment hole 8-1, so as to adjust the angle, so that the adjustment plate 6-4 can adapt to the oblique angle of the door knife 7.

[0016] The side wall of the adjustment plate 6-4 is provided with a slide groove 6-10, and the gate ball 6-7 is slidably engaged in the slide groove 6-10. The gate ball 6-7 is sleeved on the outside of the connecting rod, and the connecting rod is engaged in the slide groove 6-10, so as to realize the sliding engagement between the gate ball 6-7 and the slide groove 6-10. The four corners of the side wall of the adjustment plate 6-4 are provided with strip adjustment holes 6-8, and the four strip adjustment holes 6-8 are all screwed with second positioning bolts 6-9. The four second positioning bolts 6-9 are respectively fitted with two gate balls 6-7 in a group of two. Figure 2 As shown in , the position of the door ball 6-7 can be fixed by the second positioning bolt 6-9 to ensure the cooperation between the door ball 6-7 and the door knife 7.

[0017] Working principle: During operation, the opening and closing of the door knife 7 drives the mounting frame 6-2 through the door ball 6-7, and rotates around the first rotating shaft 6-3, so that the lock hook 6-6 and the door lock plate 6-1 are locked and opened. When the elevator car changes its oblique angle, the angle of the adjustment plate 6-4 is adjusted according to the change in the angle of the door knife 7, and the position of the adjustment plate 6-4 is fixed by the positioning mechanism 8. The position of the door ball 6-7 is fixed by the second positioning bolt 6-9 to ensure the coordination between the door ball 6-7 and the door knife 7.
