[0025] The utility model sets the left hanging plate 2 and the right hanging plate 3 on the bottom plate 1 for sliding left and right through the pulley assembly 4, and fixes the bottom plate 1 on the door frame 6 of the elevator floor door 7, and fixes the two floor doors 7 to the lower end of the left hanging plate 2 and the lower end of the right hanging plate 3 respectively, so that the opening and closing of the elevator floor door 7 are realized through the relative movement, separation and approach of the left hanging plate 2 and the right hanging plate 3, and the anti-detachment hook 5 is always clamped on the bottom plate 1 when the left hanging plate 2 and the right hanging plate 3 move on the bottom plate 1, so that the risk of the left hanging plate 2 and the right hanging plate 3 falling off the bottom plate 1 during the movement for opening and closing the door can be reduced through the anti-detachment hook 5, thereby improving the safety of the floor door 7 device when in use.
[0026] See also Figure 2-Figure 4The pulley assembly 4 is provided with four groups and is respectively located at the left and right ends of the rear side of the left hanging plate 2 and the left and right ends of the rear side of the right hanging plate 3. The pulley assembly 4 includes an upper groove wheel 41 and a lower guide wheel 42. The guide rail 11 is formed by bending on the bottom plate 1. The upper groove wheel 41 is rollingly arranged on the upper side of the guide rail 11 and the upper side arc surface of the guide rail 11 is in contact with the groove surface of the upper groove wheel 41. The lower guide wheel 42 is against the lower side of the guide rail 11.
[0027] The pulley assembly 4 moves on the guide rail 11 to reduce the degree of shaking of the left hanging plate 2 and the right hanging plate 3 during movement, thereby improving the stability of the floor door 7 device during operation; when the pulley assembly 4 moves on the guide rail 11, the groove surface of the upper groove wheel 41 fits with the upper arc surface of the guide rail 11, thereby reducing the shaking of the left hanging plate 2 and the right hanging plate 3 in the front and rear directions when moving through the cooperation and limiting effect between the upper groove wheel 41 and the guide rail 11, and the lower guide wheel 42 is against the lower side surface of the guide rail 11, thereby reducing the shaking of the left hanging plate 2 and the right hanging plate 3 in the upper and lower directions, and at the same time, the limiting effect of the lower guide wheel 42 reduces the risk of the upper groove wheel 41 shaking upward too much and causing it to detach from the guide rail 11.
[0028] See also Figure 3 A secondary lock 21 is fixed on the left hanging plate 2, a main lock 31 is fixed on the right hanging plate 3, and an intermediate door lock 12 is fixed on the base plate 1. The main lock 31 is connected to the intermediate door lock 12. Conductive contacts are provided on the main lock 31, the secondary lock 21 and the intermediate door lock. The conductive contacts on the main lock 31 and the secondary lock 21 are in contact with and electrically connected to the conductive contacts on the intermediate door lock 12.
[0029] When the elevator floor door 7 is closed, the left hanging plate 2 and the right hanging plate 3 approach each other and make the secondary lock 21 and the main lock 31 contact with the middle door lock 12, wherein the main lock 31 and the middle door lock 12 are snap-fitted and fixed, and the conductive contacts on the main lock 31 and the secondary lock 21 are electrically connected to the conductive contacts on the middle door lock 12. Therefore, the control detection circuit electrically connected to the conductive contacts of the middle door lock 12 can detect that the floor door 7 is closed, thereby being able to control the elevator car to move; when the elevator floor door 7 is opened, the door knife on the elevator car drives the main lock 31 to separate from the middle door lock 12, and opens the floor door 7 under the action of the door knife driving the main lock 31. At this time, the control detection circuit is disconnected, and the car cannot move, thereby ensuring the safety of the elevator during use.
[0030] In this embodiment, the control detection circuit adopts the elevator floor door 7 control detection circuit commonly used in the art, which is a conventional technical means in the art and will not be explained in detail in this specification.
[0031] See also Figure 3The bottom plate 1 is provided with two transmission wheels 13 symmetrically, the transmission wheels 13 are fixed to the bottom plate 1 by a connecting member 14, a steel wire rope 15 is wound around the two transmission wheels 13, both ends of the steel wire rope 15 are fixed to the left hanging plate 2, the right hanging plate 3 is fixedly connected to the steel wire rope 15, and the connection between the right hanging plate 3 and the steel wire rope 15 ( Figure 3 The two ends of the wire rope 15 are located at different upper and lower sides of the transmission wheel 13.
[0032] In this embodiment, the connection points between the two ends of the steel wire rope 15 and the left hanging plate 2 are located at the lower side of the transmission wheel 13 , and the connection point between the steel wire rope 15 and the right hanging plate 3 is located at the upper side of the transmission wheel 13 .
[0033] When the main lock 31 and the right hanging plate 3 move to the right as a whole under the action of the elevator car door knife, the connection between the wire rope 15 and the right hanging plate 3 moves to the right, and the wire rope 15 rotates clockwise under the action of the transmission wheel 13, so that the connection between the wire rope 15 and the left hanging plate 2 moves to the left, and the left hanging plate 2 moves to the left under the traction of the wire rope 15. Therefore, in the utility model, it is only necessary to drive the right hanging plate 3 to move to the right by the car door knife to simultaneously drive the left hanging plate 2 and the right hanging plate 3 to move toward and away from each other, thereby realizing the opening of the two floor doors 7 respectively fixed to the left hanging plate 2 and the right hanging plate 3.
[0034] See also Figure 3 A tension spring 9 is provided between the bottom plate 1 and the right hanging plate 3 to drive the right hanging plate 3 to move leftward.
[0035] The right hanging plate 3 moves to the left under the action of the tension spring 9, and at the same time, the right hanging plate 3 drives the left hanging plate 2 to move to the right through the wire rope 15 and the transmission wheel 13.

The lower end of the connecting member 14 is fixedly connected to the front side of the guide rail 11, which can limit the movement of the left hanging plate 2 and the right hanging plate 3 through the connecting member 14, avoiding the risk of the left hanging plate 2 and the right hanging plate 3 sliding off the guide rail 11.
[0038] See also Figure 6 , Figure 7Two mounting brackets 8 are symmetrically arranged on the rear side of the base plate 1. The upper and lower ends of the mounting brackets 8 are fixedly connected to the base plate 1 and the door pocket 6 of the elevator respectively by bolts. The mounting brackets 8 are provided with supporting claws 81, and the supporting claws 81 fit the arc surface of the bending position on the base plate 1.
[0039] When the base plate 1 is fixed to the elevator door frame 6 through the mounting bracket 8, the mounting bracket 8 is first fixed to the elevator door frame 6 through bolts, and then the arc surface at the bent position of the base plate 1 is placed on the supporting claw 81 so that the base plate 1 is hung on the elevator door frame 6, which is convenient for the installer to perform other operations.
