[0003] Currently, doctors typically review imaging films by hand or by fixing them to a simple viewing device. However, the viewing device is often in a fixed position, which is not very convenient to use. Summary of the Invention
[0004] The purpose of this invention is to provide a film viewing device.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A film viewing device includes a mounting frame. A receiving assembly for placing the film, an illumination assembly for illumination, and an adsorption assembly for fixing the film are movably disposed on one side of the mounting frame. The receiving assembly includes several housings with openings on one side. A transparent plate for attaching the film is disposed at each opening of the housing. The illumination assembly includes a light guide plate disposed on the side of the transparent plate facing the mounting frame. Several rotating wheels are disposed on the inner wall of the housings, located on the side of the transparent plate away from the light guide plate.

[0009] Preferably, the pores are frustum-shaped and the cross-sectional area of the side facing the film is larger than the cross-sectional area of the side facing the light guide plate.
[0010] Preferably, a groove is formed at the top of the shell and the top of the transparent plate. A rotating component is rotatably disposed in the groove. A push plate that fits against the transparent plate is provided at one end of the rotating component. The other end of the rotating component passes through the groove and extends out of the top surface of the shell.

[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.
[0020] like Figures 1 to 3 As shown, a film viewing device of the present invention includes a mounting frame. A receiving component for placing film, an illumination component for illumination, and an adsorption component for fixing film are movably disposed on one side of the mounting frame. The receiving component includes several housings 2 with openings on one side. A transparent plate 24 for attaching film is disposed at the opening of the housing 2. The illumination component includes a light guide plate 23 disposed on the side of the transparent plate 24 facing the mounting frame. Several rotating wheels 25 are disposed on the inner side wall of the housing 2. The rotating wheels 25 are located on the side of the transparent plate 24 away from the light guide plate 23. The adsorption component includes an electrostatic plate disposed at the periphery of the transparent plate 24. Multiple films can be placed in multiple housings 2, facilitating comparative observation of the films. The film is inserted from above the opening between the rotating wheel 25 and the transparent plate 24. The rotating wheel 25 serves to limit and guide the film. After insertion, the film is adsorbed onto the electrostatic plate, which further fixes the film. The light emitted by the light guide plate 23 is evenly distributed and shines on the film through the transparent plate 24. The evenly distributed light makes the image on the film clearer and reduces the likelihood of shadows in localized areas due to brightness differences.
[0021] A lamp tube is provided at one end of the light guide plate 23 along its length. Several light-transmitting holes are opened on the side of the light guide plate 23 facing the film. The density of the light-transmitting holes is proportional to the distance from the light-transmitting holes to the lamp tube. A reflective layer is attached inside the light guide plate 23. The light emitted by the lamp tube is continuously reflected inside the light guide plate 23 and finally emitted through the light transmission holes to illuminate the film. However, during the reflection process inside the light guide plate 23, some of the light is emitted from the light transmission holes, resulting in less light at positions farther away from the lamp tube. Through the density design of the light transmission holes, the number of light transmission holes is increased at positions farther away from the lamp tube for the same area, and the probability of light emission is increased. This compensates for the insufficient light at positions far from the lamp tube, making the light emission of the entire light guide plate 23 more uniform and easier to observe the film.
[0022] A closed space is formed between the transparent plate 24 and the shell 2. Each shell 2 has an air groove 32 that extends through the thickness of the shell 2. Each air groove 32 is connected to an air pipe. Each air pipe is connected to the same air pump through a multi-port pipe joint. The transparent plate 24 has several air holes 36. The shell 2 is also equipped with a control component for controlling the opening and closing of the air groove 32. The film is attached to the electrostatic sticker 31. Since the electrostatic sticker 31 is distributed at the edge of the transparent plate 24, air bubbles may exist between the middle of the film and the transparent plate 24, affecting the observation of the film. By using a vacuum pump to evacuate the inside of the housing 2, the air pressure inside the housing 2 is low, and the air between the transparent plate 24 and the film is drawn away through the air hole 36, so that the middle area of the film can also be tightly attached to the transparent plate 24, making it easier to observe. Through the multi-port pipe joint, one vacuum pump can evacuate the inside of multiple housings 2. By using the control component to open and close the air groove 32, the vacuum pump can only evacuate the housing 2 containing the film, which is more efficient.
[0023] The control component includes a screw 33. The housing 2 has a threaded groove that is perpendicular to and connected to the air groove 32. The screw 33 has a through groove 34 that passes through the diameter of the screw 33. The screw 33 is threaded into the threaded groove and one end of the screw passes through the housing 2. A handle 35 is provided at the end of the screw 33 that passes through the housing 2. The threaded connection provides better airtightness. Rotating the handle 35 drives the screw 33 to rotate, which is more convenient and labor-saving. When the screw 33 rotates, when the through groove 34 is in close contact with the groove wall of the threaded groove, the screw 33 seals the air groove 32, preventing air from circulating inside and outside the housing 2. The air pump cannot evacuate the inside of the housing 2. When the screw 33 rotates to the point where the through groove 34 connects with the air groove 32, the air pump can evacuate the inside of the housing 2.
[0024] The vent 36 is frustum-shaped and its cross-sectional area facing the film is larger than its cross-sectional area facing the light guide plate 23. This design increases the contact area between the pores 36 and the film, reduces the pressure on the film, and prevents the film from deforming.
[0025] A groove 4 is formed at the top of the shell 2 and the top of the transparent plate 24. A rotating member 5 is rotatably arranged in the groove 4. A push plate 6 that fits against the transparent plate 24 is provided at one end of the rotating member 5. The other end of the rotating member 5 passes through the groove 4 and extends out of the top surface of the shell 2. Due to the adsorption of the film by the electrostatic sticker 31 and air pressure, and the fact that the film itself is thin and difficult to remove, the rotating part 5 is turned by pushing the end of the housing 2, causing the rotating part 5 to rotate and drive the push plate 6 to push the film outward, so that the film is separated from the transparent plate 24 and the film can be easily removed.
[0026] An arc-shaped plate 26 is provided at the opening of the housing 2, located above the rotating wheel 25. The top of the arc-shaped plate 26 is deflected away from the transparent plate 24; the arc-shaped plate 26 serves as a guide.
[0027] The mounting bracket includes a mounting base 11 and a rotating arm 12 rotatably mounted on the mounting base 11. The rotating arm 12 includes several sub-arms, and adjacent sub-arms are connected by a damping shaft. The housing 2 is connected to the end of the rotating arm 12 by a spherical shaft. The position of the housing 2 can be adjusted up, down, forward, and backward by rotating between several sub-arms, making it suitable for various occasions and doctors' personal habits. The deflection angle of the housing 2 can be changed by the spherical rotating shaft, with a large deflection range.
[0028] The housing 2 includes two first housings 21 and two second housings 22. The two first housings 21 are connected to the same spherical rotating shaft by a connecting frame, and the second housings 22 are connected to the outside of the first housings 21 by hinges. The entire device consists of four housings 2, which are quite long, so that the second housings 22 on both sides cannot be directly in the doctor's line of sight. They are connected by hinges, allowing the second housings 22 to rotate so that they can face the doctor directly for easy observation. When the device is not in use, the second housings 22 can be rotated so that the openings of the first housing 21 and the second housing 22 are facing each other. The first housing 21 and the second housing 22 fit together to form a relatively closed space, making it difficult for external dust and other particles to adhere to the inside of the housings 2, thus reducing the frequency of cleaning.
[0029] Working principle: During use, the mounting base 11 is installed on the workbench, the position is adjusted by rotating arm 12, the angle of the first housing 21 is adjusted by spherical rotating shaft, and the arc plate 26 acts as a guide. The film is inserted through the arc plate 26 and between the rotating wheel 25 and the transparent plate 24. The film is initially fixed by electrostatic sticker 31. Initially, the through groove 34 on the screw 33 is in contact with the groove wall of the threaded groove, and the housing 2 is in a closed state. When the film is placed into the housing 2, the screw 33 is rotated 90 degrees by the handle 35 to connect the housing 2 with the air groove 32. The air pump is started to evacuate the inside of the housing 2 to further fix the film. The air pump only performs a short evacuation. After the short evacuation, the screw 33 is rotated again to close the air groove 32, so that the inside of the housing 2 is kept in a negative pressure state. After observing the film, the top of the film is deflected by turning the rotating part 5, creating a gap between the film and the transparent plate 24, making it easier to remove the film. After removing the film, the second housing 22 can be rotated to fit into the first housing 21, reducing the entry of external impurities.
