Description

Technical Field

[0002] With the combination of radiology and high technology, the position of radiology in diagnosis and treatment is becoming increasingly irreplaceable. While radiation benefits mankind, it also has a certain impact on human health. When the human body is exposed to radiation, as the radiation dose increases, certain harmful effects may occur randomly, which may induce malignant tumors such as leukemia, thyroid cancer, and bone tumors, and may also cause gene mutations and chromosomal aberrations in human genetic material. When the body is exposed to radiation that exceeds the dose limit for a long time, it may cause chronic radiation sickness, resulting in systemic chronic radiation damage mainly in hematopoietic tissue damage, which is harmful to health.

[0003] According to the application number 201921372853.2, a portable radiation protection monitoring device is disclosed, which includes a monitoring device body, a fixing plate is fixedly installed on one side of the monitoring device body, an L-shaped clamp is fixedly installed on one side of the fixing plate, a first groove is opened on one side of the fixing plate, a clamp is slidably installed in the first groove, a plurality of second grooves are opened on the side of the clamp close to the monitoring device body, one end of a reset spring is fixedly installed on the inner wall of the second groove away from the opening, and the other end of the reset spring is fixedly installed on the inner wall of the first groove.

[0004] The above scheme is used to hang the monitoring device body firmly on the clothes, so that it is easy to carry. However, the above scheme has certain limitations in actual use. In the above scheme, the rotating plate is exposed to the outside and there is no anti-rotation component on the side. When the device is hung on the clothes, if the human body performs other actions or collides with others, the vibration and friction generated at this time and the auxiliary pulling of the return spring cause the rotating plate to rotate, causing the L-shaped clamp and the clip to gradually loosen, resulting in the device being unable to be stably hung on the pocket and falling off. Therefore, there are certain shortcomings in use. Utility Model Content

[0026] The outer surfaces of the two moving frames 505 are hinged with two hinge plates 506, and one end of the two hinge plates 506 away from the outer surface of the moving frame 505 is hinged with a clamping plate 507. In this embodiment, the hinge plate 506 can push the clamping plate 507 to move in the direction of the L-shaped clamping plate 7 under the push of the moving frame 505, and the movement of the clamping plate 507 is limited and guided by the second guide groove 503, so that it moves stably, and the outer surface of the clamping plate 507 is slidably connected to the inner wall of the second guide groove 503, and the outer surface of the clamping plate 507 is fixedly connected with a plurality of anti-slip strips. In this embodiment, the anti-slip strips on the clamping plate 507 are engaged with the rubber strip 8, thereby increasing the friction and stability when clamping the pocket.

[0027] An anti-reversal mechanism 6 is provided inside the component block 2 .

[0028] See also Figure 2 , Figure 4 The anti-reversal mechanism 6 includes a second component groove 601 and a gear 606. The inner wall of the second component groove 601 is opened on the inner wall of the component block 2. The inner wall of the gear 606 is fixedly connected to the outer surface of the rotating shaft 3. The inner wall of the second component groove 601 is opened with two first sliding grooves 602, and the inner wall of the second component groove 601 is opened with an L-shaped sliding groove 603.

[0029] The inner wall of the second component groove 601 is slidably connected with a moving block 604, and the outer surface of the moving block 604 is slidably connected to the inner wall of the first slide groove 602. In this embodiment, the movement of the moving block 604 is guided by the first slide groove 602, so that the moving block 604 can move stably and directional. A side of the moving block 604 is fixedly connected with a tooth block 605, and the tooth block 605 is meshed with the gear 606. In this embodiment, the meshing teeth of the gear 606 are of a special tooth shape, one side is an inclined surface and the other side is a vertical surface, and the tooth block 605 is fixedly connected to the inner wall of the first slide groove 602.

During the movement of the moving frame 505, the clamping plate 507 can be pushed to move in the direction of the L-shaped clamping plate 7 through the connection of the hinge plate 506 to clamp and fix the pocket. Then, during the rotation of the gear 606, the meshing block 605 can be pushed to move outward. After the pushing mechanism 5 is fixed to the L-shaped clamping plate 7, the shaft 3 stops rotating. Under the special meshing engagement of the meshing block 605 and the gear 606, The gear 606 cannot rotate, and the teeth of the tooth block 605 are stably inserted into the gear 606 under the push of the spring 607, so that the pushing mechanism 5 and the L-shaped clamp 7 can stably clamp and fix the pocket. Finally, when the bite needs to be released, the sliding slider 609 drives the moving block 604 to move, so that the tooth block 605 moves away from the gear 606 to release the mesh, so that it can rotate to release the clamping of the pocket. When the slider 609 slides to the other slot of the L-shaped slot 603, the slider 609 can limit the moving block 604, and under the push of the spring 607, the slider 609 squeezes the inner wall of the L-shaped slot 603, so that the slider 609 drives the moving block 604 to always be away from the gear 606.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
