Fig. 2 is an enlarged view of a portion a of the clean room transfer window of the present invention shown in fig. 1.

Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

referring to fig. 1, a clean room transfer window includes a box body 10 with two ends communicated, two ends of the box body 10 are provided with windows 20, the windows 20 are rotatably connected with the box body 10 through a rotating shaft 12, the middle part of the rotating shaft 12 is fixedly connected with the windows 20, two ends of the rotating shaft 12 are rotatably connected with the box body 10, and an automatic door closing device 30 is arranged above the box body 10.

The number of the automatic door closing devices 30 is 2, and the automatic door closing devices 30 are correspondingly arranged above the windows 20 at the two ends of the box body 10. The automatic door closing device 30 can be used to close the doors 20 at both sides of the box 10, so as to prevent the doors 20 at one end from being in an unclosed state, and when the doors 20 at the other end are opened, the outside air directly enters the clean room through the transmission window.

Referring to fig. 2, the automatic door closing device 30 includes a take-up pulley 31 and a tension spring 32, the upper end of the rotating shaft 12 extends out of the box body 10 and is fixedly connected with the take-up pulley 31, the take-up pulley 31 and the rotating shaft 12 are located on the same axis, one end of the tension spring 32 is fixedly connected with the top of the box body 10, the tension spring 32 is connected with the take-up pulley 31 through a pulling rope 33, one end of the pulling rope 33 is fixedly connected with the other end of the tension spring 32, and the other end of the pulling rope 33 is fixedly connected with the take-up pulley 31.

When people open the window 20, the rotating shaft 12 fixedly connected with the window 20 rotates to drive the take-up pulley 31 on the rotating shaft 12 to rotate together, so that the pulling rope 33 is wound on the surface of the take-up pulley 31, and meanwhile, the other end of the pulling rope 33 stretches the tension spring 32, so that the tension spring 32 keeps a stretched state in the process of opening the window 20.

When people remove the external force of opening window and door 20, extension spring 32 restores to the original state under the condition of losing exogenic action, pull rope 33 is tensile towards extension spring 32 direction, pull rope 33 and take-up pulley 31 fixed connection one end are drawn take-up pulley 31 and are rotated towards the opposite direction, take-up pulley 31 drives pivot 12 and rotate towards the opposite direction to rotate window and door 20 towards box 10 one side, reach the purpose of automatic closing the door, avoided people to forget to close window and door 20 after opening window and door 20, the condition that leads to box 10 long-time and outside air contact takes place.

In the above solution, the window and door 20 and the box body 10 may be closed and locked by an electromagnetic lock, which is not shown in this embodiment. The interlocking function can be realized by using the electromagnetic lock, so that when the window door 20 at one end is opened, the window door 20 at the other end can not be opened, the box body 10 can not form a complete channel, the outside air can not directly enter a clean room, and the air pollution to the clean room is avoided.

The side of the box body 10 far away from the rotating shaft 12 is provided with a stop block 11, the stop block 11 is positioned in the box body 10, and the stop block 11 can prevent the window and door 20 from being excessively closed, so that the window and door 20 is sunk into the box body 10. The side of the window 20 close to the box 10 is provided with a buffer strip 21, the buffer strip 21 corresponds to the stop 11, and the buffer strip 21 is used for absorbing the impact force of the window 20 on the stop 11 when the window 20 is automatically closed, thereby preventing the window 20 from being damaged when being closed and reducing the noise generated when the window 20 is closed.

The side of the window 20 far away from the box 10 is provided with a handle 22 for opening the window 20. When the person opens the window/door 20, the person can open the window/door by holding the handle 22.

The utility model provides a toilet's pass-through box is equipped with automatic door closing device in the box top, and automatic door closing device includes take-up pulley and extension spring, and box and take-up pulley fixed connection are extended to the pivot upper end, and extension spring one end and box top fixed connection are connected through the tractive rope between extension spring and the take-up pulley. When people open the window, the rotating shaft fixedly connected with the window rotates to drive the take-up pulley on the rotating shaft to rotate together, so that the traction rope is wound on the surface of the take-up pulley, and meanwhile, the tension spring is stretched by the other end of the traction rope, so that the tension spring is kept in a stretching state in the process of opening the window; when people will open the external force of window and door and remove, the extension spring is the reconversion under the condition that loses exogenic action, and the traction rope is tensile towards the extension spring direction, and traction rope and take-up pulley fixed connection one end are drawn the take-up pulley and are turned towards the opposite direction, and the take-up pulley drives the pivot and turns towards the opposite direction to rotate window and door towards box one side, reach the automatic mesh of closing the door, avoided people to forget after opening the window and door and close the window and door, lead to the box to take place with the condition of outside air contact for a long time.

It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention, and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
