In addition, the technical features involved in the different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0041] Example 1

[0042] This embodiment provides a medical door, such as Figure 1 As shown, it includes a shell 1, a driving member 2, a transmission assembly and a door body 3. The transmission assembly includes a driving wheel 4, a driven wheel 5, a driving belt 6, two load-bearing hanging wheels 7, two driving hanging wheels 8 and a medical door status detection device.

[0043] The driving member 2 is fixed in the housing 1, the driving wheel 4 and the driven wheel 5 are both hinged to the housing 1, the driving belt 6 is sleeved on the driving wheel 4 and the driven wheel 5, the driving wheel 4 is connected to the driving member 2, and the driving wheel 4 can be driven by the driving member 2 to rotate and drive the driving belt 6. The driving member 2 is preferably a motor.

[0044] In this embodiment, two load-bearing hanging wheels 7 are connected to two door bodies 3 respectively, and any load-bearing hanging wheel 7 is slidably connected to the shell 1 or the door body 3. Specifically, the bottom of the load-bearing hanging wheel 7 is fixedly connected to the door body 3, and the upper part of the load-bearing hanging wheel 7 is slidably connected to the shell 1. For example, the upper part of the load-bearing hanging wheel 7 is provided with a groove, and the side of the shell 1 is slidably arranged inside the groove. Therefore, when the door body 3 moves, the load-bearing hanging wheel 7 can pull the door body 3 connected thereto without hindering the movement of the door body 3. As an alternative, the upper part of the load-bearing hanging wheel 7 is fixed to the shell 1, and the lower part of the load-bearing hanging wheel 7 is provided with a groove, and a component slidably arranged inside the groove is correspondingly provided on the door body 3, and the side wall of the groove can apply an upward force to the door body 3 through this component.

[0045] In this embodiment, the two driving hanging wheels 8 are respectively connected to the two door bodies 3, and the two driving hanging wheels 8 are respectively connected to the driving belts 6 on both sides of the driving wheel 4 and the driven wheel 5 to drive the two door bodies 3 to move in different directions.

[0046] Specific as Figure 1 As shown, in Figure 1The driving hanging wheel 8 on the left side is connected to the left door body 3 and the driving belt 6 is connected to the upper part of the driving wheel 4 and the driven wheel 5. Figure 1 The driving hanging wheel 8 on the middle side is connected to the right door body 3 and the driving belt 6 is connected to the lower part of the driving wheel 4 and the driven wheel 5. Therefore, when the driving belt 6 moves, the two driving hanging wheels 8 can drive the two door bodies 3 to be closed or opened.

[0047] Medical automatic doors are used dozens of times more frequently than ordinary household doors. Hardware is very easy to be damaged. In addition, since they are located in public places, they cannot avoid various damages such as collision with hospital beds and corrosion from cleaning agents. At present, when an accident occurs, users can only be asked to stop using them and urgently dispatch professional maintenance personnel to the site for maintenance. The focus of maintenance is mainly on the working condition of the belt: generally, the distance between the ground wheel and the three-side frame is adjusted, or the hanger wheel is adjusted to raise the door body 3 positions, or a small-sized silicone seal is replaced, etc. This maintenance method is too complicated and inefficient.

[0048] Therefore, in this embodiment, a medical door state detection device is also provided, which includes a grating fixed on the driven wheel 5 in the medical door transmission assembly. The grating is configured to receive external laser light, and the degree of the shaft deviation of the driven wheel 5 is determined by judging the color state of the grating being illuminated.

[0049] The device uses a grating to roughly measure the displacement of the rotating shaft of the driven wheel 5, so as to judge abnormal working conditions such as belt aging and increased resistance due to foreign matter, thereby improving maintenance quality and extending product life.

[0050] Example 2

[0051] This embodiment provides a medical door state detection device, which is used for the medical door in Embodiment 1. The medical door state detection device includes a grating, which is fixed on the driven wheel 5 in the medical door transmission assembly. When in use, the grating is configured to receive external laser light, and the degree of deviation of the rotating shaft of the driven wheel 5 is determined by judging the color state of the grating being illuminated.

[0052] In this embodiment, in order to facilitate observation of the color state of the illuminated grating, different colors are used for the odd-numbered sequence and the even-numbered sequence on the grating.

[0053] As an implementation, the gratings at odd-numbered sequences on the gratings use red stripes, and the gratings at even-numbered sequences on the gratings use green stripes. Alternatively, the gratings at odd-numbered sequences on the gratings use green stripes, and the gratings at even-numbered sequences on the gratings use red stripes.

[0054] When in use, a white laser beam is irradiated onto the grating surface through a laser pen. We use pure red to create the left image ( Figure 2 In the middle label c), use pure green to make the right image ( Figure 2d), by observing from the direction parallel to the grating whether the illuminated color is mainly red or green, the deviation of the rotation axis of the driven wheel 5 can be determined. During this process, the laser pen keeps its position unchanged.

[0055] Specifically, red appears when white light is irradiated on a red object, and green appears when irradiated on a green object. Therefore, when printing gratings, odd-numbered sequence gratings are red stripes, and even-numbered sequence gratings are green stripes. If the driven wheel 5 deflects the rotation axis and causes the grating position on it to deflect, since the incident light is fixed, the white light will irradiate on the red strip or the green strip according to the different deflection angles. At the edge of the grating lens, it can be determined which color strip is illuminated, and then the offset of the driven wheel 5 can be determined.

[0056] For example, taking the image observed after the laser is irradiated on the grating when the grating is in the normal position as the reference, if the grating position on the grating is deflected due to the deflection of the shaft of the driven wheel 5, the position of the laser irradiation on the grating changes, and then the image observed on the grating also changes accordingly. Through comparative analysis, the deviation of the shaft of the driven wheel 5 can be obtained. Specifically, this comparative analysis process is not the focus of the present application. The present application intends to provide a detection device capable of detecting the state of a medical door, so its analysis process will not be repeated here.

[0057] In this embodiment, the grating is made of 200 lines and 0.8 mm thin glass. Irradiation perpendicular to the grating direction can achieve a resolution of 2.5 degrees, and the angular resolution can be less than 1 degree when irradiated at an angle of 20 degrees, so the deviation of the rotation axis of the driven wheel 5 can be roughly determined. Among them, the 20-degree inclination angle means that the angle between the grating surface and the laser it receives is 20 degrees.

[0058] Example 3

[0059] This embodiment provides a medical door status detection method, using the medical door status detection device in Embodiment 2, and comprising the following steps:

[0060] Step 1: Irradiate the grating surface with white laser;

[0061] Step 2: Observe the main color of the illuminated grating from the direction parallel to the grating to determine the offset of the rotating shaft of the moving wheel.

[0062] Specifically, the odd-numbered sequence gratings are red stripes, and the even-numbered sequence gratings are green stripes. If the driven wheel 5 rotates to drive the grating position thereon to deflect, since the incident light is fixed, the white light will shine on the red stripe or the green stripe according to the different deflection angles. At the edge of the grating lens, it can be determined which color stripe is illuminated, and then the deviation of the driven wheel 5 can be determined.

[0063] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
