[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] like Figure 1-4 As shown, the utility model provides a railway toilet door and shutter for disabled persons, which is installed on an accessible toilet door 1 and a partition wall 2. An opener and closer mechanism 3 is arranged on one side of the accessible toilet door 1 and near the upper edge. The opener and closer mechanism 3 comprises a mounting box 31, a motor 36 and a limit strip 310. A fixing member 35 is arranged inside the mounting box 31. A drawstring belt 37 is arranged inside the fixing member 35. A fixing block 32 is fixedly installed on the other end of the drawstring belt 37. Through holes 34 are penetrated at both upper and lower ends of the fixing member 35. A rotating shaft 39 is arranged inside the through hole 34. A clockwork spring 38 is fixedly connected to the side wall of the rotating shaft 39 and near the upper end. A mounting plate 33 is fixedly installed on the upper end of the fixing member 35.

[0025] The following is a detailed description of the specific settings and functions of this embodiment. When the drawstring 37 is extended to the maximum length, the motor 36 stops working. At this time, the deformation of the clockwork spring 38 caused by the rotation of the shaft 39 slowly recovers, driving the shaft 39 to rotate in the opposite direction, thereby tightening the drawstring 37. Since the other end of the drawstring 37 is fixed to the barrier-free toilet door 1 through the fixing block 32, when the drawstring 37 is tightened, it will drive the barrier-free toilet door 1 to slide and close, greatly facilitating the door closing operation for disabled people.

[0026] Embodiment 2

[0027] like Figure 1-4As shown, a handrail 4 is fixedly installed on one side of the barrier-free toilet door 1 and near the edge, and door opening buttons 5 are fixedly installed on both sides of the partition wall 2. One side of the installation box 31 is fixed to one side of the partition wall 2, one side of the fixing block 32 is fixed to one side of the barrier-free toilet door 1, the other end of the clockwork spring 38 is fixed to the mounting plate 33, the upper and lower ends of the limit strip 310 are respectively fixed to the inside of the fixing member 35 and are located at the upper and lower surface positions, the lower end of the rotating shaft 39 is transmission-connected to the output end of the motor 36 through the through hole 34, the lower end of the motor 36 is fixed to the inner wall of the installation box 31, one end of the drawstring 37 is fixed to the outer wall of the rotating shaft 39, and the distance between one side of the limit strip 310 and the side closer to the inside of the fixing member 35 is twice the thickness of the drawstring 37, and the maximum stretching length of the drawstring 37 is the same as the width of the barrier-free toilet door 1.

[0028] The effect achieved by the entire embodiment is that by pressing the door opening button 5 on the outside, the motor 36 and the sliding opening system of the barrier-free toilet door 1 are started at the same time. When the barrier-free toilet door 1 slides open, the motor 36 drives the rotating shaft 39 to rotate. When the rotating shaft 39 rotates, it drives one end of the drawer belt 37 to continuously stretch and drives the elastic end of the clockwork spring 38 to expand outward, so that the barrier-free toilet door 1 can be opened and closed freely, allowing disabled people to enter the toilet.

[0029] The usage and working principle of this device are as follows: first, the disabled person presses the door opening button 5 outside, and at the same time starts the motor 36 and the sliding opening system of the barrier-free toilet door 1. While the barrier-free toilet door 1 slides open, the motor 36 drives the rotating shaft 39 to rotate. When the rotating shaft 39 rotates, it drives one end of the drawstring 37 to continuously stretch out, and drives the elastic end of the spring spring 38 to expand outward, so that the barrier-free toilet door 1 can be opened and closed freely, allowing the disabled person to enter the toilet. When the drawstring 37 is stretched to the maximum length, the motor 36 stops working. At this time, the deformation of the spring spring 38 caused by the rotation of the rotating shaft 39 slowly recovers, driving the rotating shaft 39 to rotate in the opposite direction, and then tightening the drawstring 37. Since the other end of the drawstring 37 is fixed to the barrier-free toilet door 1 through the fixing block 32, when the drawstring 37 is tightened, it will drive the barrier-free toilet door 1 to slide and close, which greatly facilitates the door closing operation of the disabled person.

[0030] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
