Wherein: 1-door cutter base plate, the left blade of 2-, the right blade of 3-, 4-rocker, 5-rocking bar, the upper connecting rod of 6-, 7-lower link, 8-arm-tie, 9-extension spring, 10-is anti-takes off blade, 11-arm-tie shifting shaft, the upper bank of 12-, 13-gate link plate, 14-is anti-takes off latch hook, and pin stirred by 15-latch hook, 16-is anti-takes off positioning plate, the upper connecting rod limiting stopper of 17-, 18-deep groove ball bearing.

Detailed description of the invention

Fig. 1 to Fig. 4 illustrates this anti-specific embodiment taking off type door opening machine for elevator of the utility model, identically with traditional door opener be, this door opening machine for elevator also comprises bank 12, the motor (not shown in FIG.) be fixed on bank, the motor transmission belt (not shown in FIG.) be connected with motor and be slidably arranged in gate link plate on upper bank 13 (gate link plate is generally two pieces, left and right, for drawing conveniently, in Fig. 1, illustrate only a piece wherein).Described gate link plate 13 has been bolted a cutter base plate 1, and the front of this cutter base plate 1 is provided with left blade 2, right blade 3, prevents taking off blade 10, rocker 4, rocking bar 5, upper connecting rod 6 and lower link 7.Wherein, rocker 4 and rocking bar 5 are all hinged on a cutter base plate 1, and rocker 4 is positioned at the top of rocking bar 5, rocker 4 has three coupling ends of distribution triangular in shape, one of them coupling end is connected with described motor transmission belt, all the other two coupling ends are hinged on left blade 2 and right blade 3 respectively, and the two ends of rocking bar 5 are hinged on left blade 2 and right blade 3 respectively, describedly anti-take off blade 10 and are positioned at the left side of left blade 2 and are hinged on a cutter base plate 1 by described upper connecting rod 6 and lower link 7.Described upper bank 12 is provided with one to prevent taking off positioning plate 16, described gate link plate 13 is hinged with an energy flip-flop movement and anti-ly take off anti-that positioning plate matches with described and take off latch hook 14, so-called " cooperatively interacting ", refer to: when anti-take off latch hook 14 be turned to the first control position time, anti-latch hook 14 of taking off is hooked on anti-taking off on positioning plate 16 and makes the two be fixed together; When preventing that taking off latch hook 14 is turned to the second control position, anti-latch hook of taking off from preventing that taking off positioning plate 16 disengaging comes, and makes the two be separated from each other.Described anti-taking off on latch hook 14 forms slanted bar hole (bar hole of inclination), described anti-taking off blade 10 is provided with the latch hook stretched in described slanted bar hole is stirred pin 15, when preventing taking off blade 10 action, its band moveable lock hook stirs pin 15 action, and then make latch hook stir pin 15 to drive and anti-take off latch hook 14 and make rotary movement, thus anti-latch hook 14 of taking off optionally is made to take off positioning plate 16 and mutually lock with anti-or be separated from each other.

The key improvements of the present embodiment is: this door opening machine for elevator also comprises arm-tie 8 and an extension spring 9, wherein, extension spring 9 has the upper end be connected with door cutter base plate 1 and the bottom be connected with arm-tie 8, arm-tie 8 has takes off the left part that blade 10 is hinged, the right part be connected with extension spring 9 bottom and the pars intermedia be hinged with door cutter base plate 1 with anti-, and described left blade 2 is fixed with the arm-tie shifting shaft 11 contacting with arm-tie 8 and coordinate.

The two structure is caused to be damaged for avoiding arm-tie shifting shaft 11 and arm-tie 8 because of Long Term Contact friction, this example has installed a deep groove ball bearing 18 on arm-tie shifting shaft 11, and this deep groove ball bearing 18 is contacted with arm-tie 8 coordinate, and no longer allow arm-tie shifting shaft 11 and arm-tie 8 directly contact.

In order to strengthen the fitment stability between deep groove ball bearing 12 and arm-tie 8, the present embodiment additionally uses following structure: the part between the pars intermedia of described arm-tie 8 and right part is arc-shaped structure, and described deep groove ball bearing 18 is positioned at the top of this arc-shaped structure.As Fig. 4.

Again shown in composition graphs 1 ~ Fig. 4, now the principle of work of the present embodiment is simply described below:

1, when elevator enters flat bed and door machine controller receives enabling signal, motor action, motor transmission belt drives rocker 4 to rotate counterclockwise in fig. 2.Rocker 4 drive left blade 2 and right blade 3 close to each other, wherein left blade 2 also can move down while moving right, the arm-tie shifting shaft 11 be fixed on left blade 2 will move down with left blade 2, deep groove ball bearing 18 fixing on arm-tie shifting shaft 11 arm-tie 8 of conflicting in the process moved down rotates clockwise (extension spring 9 tension is elongated) in fig. 2, the left part of arm-tie 8 is upwards lifted and provokes and anti-take off blade 10 and move up, be fixed on and prevent that the latch hook taking off blade 10 is stirred pin 15 and moved up together thereupon, thus drive prevents that taking off latch hook 14 makes rotary movement, make to prevent taking off latch hook 14 and preventing that taking off positioning plate 16 is separated from each other, gate can normally be opened.

2, when car is in non-level position, car door is closed, motor action, and motor transmission belt drives rocker 4 to rotate clockwise in fig. 2.Rocker 4 drive left blade 2 and right blade 3 mutually away from, wherein left blade 2 also can move up while being moved to the left, the arm-tie shifting shaft 11 be fixed on left blade 2 will move up with left blade 2, deep groove ball bearing 18 fixing on arm-tie shifting shaft 11 moves up and departs from arm-tie 8, under the pulling force effect of extension spring 9, arm-tie 8 rotates counterclockwise in fig. 2, the left part of arm-tie 8 moves down and drives and anti-take off blade 10 and move down, be fixed on and prevent that the latch hook taking off blade 10 is stirred pin 15 and moved down together thereupon, thus drive prevents that taking off latch hook 14 does reverse flip action, make to prevent taking off latch hook 14 and preventing that taking off positioning plate 16 locks mutually, gate cannot be opened.Effectively stop when elevator enters non-level position passenger to push gate aside, completely eliminate potential safety hazard.

In addition, this example be fixed with on door cutter base plate 1 with described on connecting rod 6 contact the upper connecting rod limiting stopper 17 coordinated.When being in non-level position to prevent car, anti-take off blade 10 to move down stroke excessive, cause arm-tie 8 and deep groove ball bearing 18 that serious dislocation and cannot cooperating occurs.

Certainly, above-described embodiment, only for technical conceive of the present utility model and feature are described, its object is to people can be understood content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations of doing according to the Spirit Essence of the utility model main technical schemes or modification, all should be encompassed within protection domain of the present utility model.
