Description

Technical Field

[0001] This utility model relates to a medical film reading lightbox, belonging to the technical field of medical imaging film data reading instruments. Background Technology

[0002] In clinical practice, medical film reading light boxes are mainly used for reading imaging films. Their structure includes a box body, a light source, an observation panel, and a film clipping device. The light source diffuses light evenly through the observation panel, illuminating the imaging film. Some light boxes are also equipped with a brightness adjustment knob. The film clipping device is used to hold the imaging film; currently, common clipping devices include spring clips or slot-type clips.

[0003] However, both common spring clips and slotted film clips have the problem of being too tight or too loose. Spring clips lose elasticity after repeated use, making it difficult to hold the film securely. Slotted film clips, if dimensionally inaccurate, cannot fit tightly against the film, and the film will fall off with the slightest movement, affecting the continuity and efficiency of the doctor's image reading. Conversely, when forcefully inserting the CT film to prevent slippage, difficulty in removal arises, requiring the doctor to spend considerable time and effort to pull it out, and potentially damaging or deforming the film due to improper force, affecting the accuracy of subsequent diagnoses. These problems not only reduce image reading efficiency but also cause numerous inconveniences in clinical work.

[0004] Therefore, a medical film reading lightbox was designed, which uses a smoother ball bearing structure to hold the imaging film and can adjust the clamping force as needed, thereby improving the efficiency of film reading. Summary of the Invention

[0005] The technical problem to be solved by this utility model is to provide a medical film reading light box that solves the problem that the current medical film reading light boxes hold the film too tightly or too loosely.

[0006] The technical problem to be solved by this utility model is achieved by the following technical solution:

[0007] A medical film viewing light box includes a box body with a light-emitting front and a light-transmitting observation panel covering the front of the box body. A ball bearing clamping assembly for holding image films is fixed to the top of the front of the box body.

[0008] The ball bearing clamping assembly includes an upper frame, a guide strip, ball bearing bodies, and an elastic mechanism. The upper frame is fixed to the top of the front of the housing, and the guide strip is fixed to the front of the upper frame. A clamping groove for accommodating the image film is provided between the guide strip and the upper frame. The clamping groove gradually narrows from the bottom opening to the top. The upper frame has an inner cavity for installing the elastic mechanism. Multiple horizontal through holes for accommodating the ball bearing bodies are opened on the front of the upper frame. Each ball bearing body is pushed out from the horizontal through hole of the upper frame by a set of elastic mechanisms and contacts the guide strip. The image film is inserted into the clamping groove and pressed against the guide strip by the ball bearing body.

[0009] Preferably, the elastic mechanism includes a spring and an adjustable retainer for adjusting the spring compression from the inner end of the spring.

[0010] Preferably, the adjustable fixing component includes a first slider, a second slider, and an adjusting screw. The inner end of the spring is connected to the first slider. The top of the first slider is provided with a first inclined surface. The second slider is located on top of the first slider. The bottom of the second slider is provided with a second inclined surface that cooperates with the first inclined surface. The adjusting screw is screwed to the top of the upper frame. The bottom of the adjusting screw extends into the inner cavity and is rotatably mounted on the top of the second slider. When the adjusting screw rotates and drives the second slider to move downward, the second inclined surface presses against the first inclined surface, thereby driving the first slider to further press against the spring.

[0011] Preferably, one of the first inclined surface and the second inclined surface has a raised rib along the sliding direction on one surface, and a sliding groove that cooperates with the raised rib on the other surface.

[0012] Preferably, the first slider is provided with multiple guide posts parallel to the direction of the spring axis, and the inner cavity of the upper frame is provided with guide holes that cooperate with the guide posts.

[0013] Preferably, the adjusting screw has a coaxially arranged hollow hole inside, the top of the second slider is fixed with a central shaft that mates with the hollow hole, the adjusting screw is sleeved on the central shaft, and the top of the adjusting screw is limited by a retaining ring that is locked at the upper end of the central shaft.

[0014] Preferably, the top end of the adjusting screw is provided with a groove, and the retaining ring is fixed to the decorative piece at the top of the adjusting screw and hidden in the groove.

[0015] The beneficial effects of this utility model are:

[0016] (1) The upper frame and guide strip form a clamping groove that narrows from wide to narrow. It does not need to be perfectly aligned. The film can be smoothly inserted into the clamping groove by relying on the guide strip.

[0017] (2) The ball body is pressed by an elastic mechanism, which can exert pressure on the image film in the clamping slot so as to fix the upper edge of the image film. When inserting or withdrawing, the image film contacts the ball body, making the operation smoother.

[0018] (3) The elastic mechanism is adjusted by the adjusting screw. Whether it is too loose due to long-term use or too tight or too loose due to changes in the thickness of the imaging film, the clamping force can be changed by adjusting the spring pressure. Attached Figure Description

[0032] In order to make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0033] like Figures 1-5 As shown, this medical film reading light box is used for reading medical imaging film 7 data. It includes a box body 1 with a light-emitting front and a light-transmitting observation panel 2 covering the front of the box body 1. A ball bearing clamping assembly for clamping the imaging film 7 is fixed on the top of the front of the box body 1.

[0034] like Figures 1-3 As shown, the ball clamping assembly includes an upper frame 3, a guide strip 4, a ball body 5, and an elastic mechanism 6. The upper frame 3 is fixed to the top of the front of the housing 1, and the guide strip 4 is fixed to the front of the upper frame 3. A clamping groove 401 for accommodating the image film 7 is provided between the guide strip 4 and the upper frame 3. The clamping groove 401 gradually narrows from the bottom opening to the top, which facilitates the insertion of the image film 7 into the clamping groove 401 from below. The upper frame 3 has an inner cavity 301 for installing the elastic mechanism 6. Multiple horizontal through holes 302 for accommodating the ball bodies 5 are opened on the front of the upper frame 3. Each ball body 5 is pushed out from the horizontal through hole 302 of the upper frame 3 by a set of elastic mechanisms 6 and comes into contact with the guide strip 4. The image film 7 is inserted into the clamping groove 401 and pressed onto the guide strip 4 by the ball body 5.

[0035] like Figure 3 As shown, in some embodiments, the elastic mechanism 6 includes a spring 601 and an adjustable fastener for adjusting the degree of compression of the spring 601 from its inner end.

[0036] like Figure 3 , Figure 4 As shown, in some embodiments, the adjustable fixing member includes a first slider 602, a second slider 603, and an adjusting screw 604. The inner end of the spring 601 is connected to the first slider 602. The top of the first slider 602 is provided with a first inclined surface 605. The second slider 603 is provided on the top of the first slider 602. The bottom of the second slider 603 is provided with a second inclined surface 606 that cooperates with the first inclined surface 605. The adjusting screw 604 is screwed to the top of the upper frame 3. The bottom of the adjusting screw 604 extends into the inner cavity 301 and is rotatably mounted on the top of the second slider 603. When the adjusting screw 604 rotates and drives the second slider 603 to move downward, the second inclined surface 606 presses against the first inclined surface 605, thereby driving the first slider 602 to further press against the spring 601.

[0037] like Figure 5 As shown, in some embodiments, one of the first inclined surface 605 and the second inclined surface 606 is provided with a rib 607 along the sliding direction, and the other surface is provided with a groove 613 that cooperates with the rib 607.

[0038] The protruding rib 607 cooperates with the sliding groove 613 to prevent misalignment of the first inclined surface 605 and the second inclined surface 606.

[0039] like Figures 3-5 As shown, in some embodiments, the first slider 602 is provided with multiple guide posts 608 parallel to the axial direction of the spring 601, and the inner cavity 301 of the upper frame 3 is provided with guide holes 303 that cooperate with the guide posts 608.

[0040] The guide post 608 cooperates with the guide hole 303, making the operation of the first slider 602 and the second slider 603 more stable.

[0041] like Figure 5 As shown, in some embodiments, the adjusting screw 604 has a coaxially arranged hollow hole inside, and a central shaft 609 that mates with the hollow hole is fixed to the top of the second slider 603. The adjusting screw 604 is sleeved on the central shaft 609, and the top end of the adjusting screw 604 is limited by a retaining ring 610 that is locked at the upper end of the central shaft 609. Preferably, the adjusting screw 604 is hand-tightened.

[0042] Working principle:

[0043] If the spring 601 becomes loose after prolonged use, rotating the adjusting screw 604 causes the second slider 603 to move downwards. Utilizing the mating first inclined surface 605 and second inclined surface 606, this drives the first slider 602 to compress the spring 601, increasing the spring 601's clamping force on the ball bearing body 5. This prevents the ball bearing body 5 from becoming loose and failing to hold the image film 7. If the ball bearing body 5 is too tight (e.g., the inserted image film 7 is too thick), making insertion difficult, the adjusting screw 604 is rotated in the opposite direction. The second slider 603 moves upwards, and under the restoring force of the spring 601, the first slider 602 retracts, reducing the spring 601's compression. This ensures the compression force on the ball bearing body 5 is moderate, neither too tight nor too loose.

[0044] like Figure 5 As shown, in some embodiments, the top end of the adjusting screw 604 is provided with a groove 611, and the retaining ring 610 is fixed to the decorative piece 612 on the top of the adjusting screw 604, which is hidden in the groove 611.

[0045] The retaining ring 610 is hidden within the groove 611, which facilitates the installation of the adjusting screw 604 and prevents the retaining ring 610 from protruding and interfering with the hand-tightening operation. The decorative piece 612 covers the retaining ring 610 and the groove 611, which not only serves an aesthetic purpose but also prevents fingers from being scratched by the retaining ring 610 during rotation.

[0046] The advantages of this medical film reading lightbox are as follows:

[0047] The upper frame 3 and the guide strip 4 form a clamping groove 401 that narrows from wide to narrow. It is not necessary to align them perfectly. The image film 7 can be smoothly inserted into the clamping groove 401 by relying on the guide strip 4.

[0048] The ball body 5, which is pressed by the elastic mechanism 6, can exert pressure on the image film 7 in the clamping groove 401 so as to fix the upper edge of the image film 7. When inserted or withdrawn, the image film 7 contacts the ball body 5, making the operation smoother.

[0049] The elastic mechanism 6 is adjusted by the adjusting screw. Whether it is too loose due to long-term use or too tight or too loose due to changes in the thickness of the imaging film 7, the clamping force can be changed by adjusting the pressure of the spring 601.

[0050] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
