Description

Technical Field

[0001] The utility model relates to the technical field of radiation protection doors, in particular to a medical manual radiation protection door. Background Art

[0002] The radiation-proof door of the hospital's radiology department is a specially designed door used to prevent radiation from leaking to other areas. The radiation-proof door of the radiology department is usually made of materials such as lead plates or lead glass, because lead can effectively block or absorb most of the radiation. The sealing performance of the door is also very important to ensure that radiation does not leak out through the door gap.

[0003] Ordinary manual radiation proof doors are very heavy, with a door leaf weighing approximately 200-400ka or more. The traditional hinge mode, due to the hinge gap problem, will lead to inconsistent door gap width after installation, and the door leaf will fall after long-term use, and the door will not be closed tightly. In the conventional top and bottom axis system, the ground axis has weak bearing capacity and the top axis has insufficient self-locking force. Therefore, relatively high requirements are placed on the reliability of the door axis of the manual radiation proof door. The top and bottom door axes must have strong bearing capacity and firm locking. In the case of frequent opening and closing, the door axis will not sink due to pitting corrosion caused by excessive pressure, and the door leaf will not be off-axis. Therefore, we proposed a medical manual radiation proof door to solve the above problems. Utility Model Content

[0007] A first connecting component, which is fixedly disposed in the first groove and is used to connect the front door panel to the overall door frame and serves as the opening and closing rotation center of the radiation-proof door;

[0008] The second connecting component is fixedly arranged on one side of the front door panel and is located on the same side as the first groove, and is used for connecting the front door panel with the overall door frame to realize the opening and closing and load-bearing of the radiation-proof door.

[0009] In one possible design, the first connecting component includes an axle box, which is embedded in the first groove, and two first threaded holes are equidistantly arranged on one side of the axle box, and bolts are threadedly connected in the two first threaded holes. The axle box is threadedly connected to the front door panel via the bolts in the two first threaded holes, and a rotating arm is rotatably connected in the axle box, and a connecting arm is rotatably connected to the top of the rotating arm, and a connecting column is rotatably connected to one end of the connecting arm, and an axle pin is fixedly connected to the top of the connecting column, and the axle pin passes through the axle box and the front door panel respectively and is slidably connected to the axle box and the front door panel, and an L-shaped axle bracket is fixedly connected to the top of the axle box, and an axle sleeve is embedded and fixedly connected to the axle bracket, and the axle pin passes through the axle sleeve and is inserted into the door frame sleeve.

[0010] In a possible design, the second connecting component includes an L-shaped ground axis bracket, which is fixedly arranged at the bottom of one side of the front door panel, and a ground axis sleeve is fixedly connected to the ground axis bracket, and the ground axis pin is inserted into the ground axis sleeve.

[0011] In a possible design, a clearance groove is provided on the rotating arm, a hexagon socket pull rod screw is threadedly connected to one side of the axis box, and one end of the hexagon socket pull rod screw passes through the clearance hole and is slidably connected to the inner wall of the clearance groove.

[0012] In a possible design, a third groove is opened on one side of the front door panel, an inner wall on one side of the third groove is fixedly connected with an aluminum honeycomb, the inner walls on four sides of the third groove are fixedly connected with the same lead plate, and the aluminum honeycomb is located between the front door panel and the lead plate, one side of the front door panel is connected to the rear door panel, and the rear door panel is located at the opening of the third groove, a plurality of card slots are fixedly provided at equal intervals on one side of the rear door panel close to the front door panel, a plurality of card blocks corresponding to the card slots are fixedly provided in the third groove, and the card blocks are carded with the corresponding card slots.

[0013] In a possible design, the inner walls on the four sides of the integral door frame are provided with mounting holes for convenient fixing to the wall.

[0014] In a possible design, one side of the inner wall of the axis box is threadedly connected with a limiting bolt for limiting the position of the hexagon socket pull rod screw.

[0017] In the present application, the stable load-bearing and convenient opening and closing of the radiation-proof door are achieved through the coordinated use of the ground axis bracket and the ground axis sleeve in the first connecting component and the sky axis box, rotating arm, connecting arm, connecting column and sky axis pin in the second connecting component. When the ground axis pin is inserted into the ground axis sleeve, the sky axis pin passes through the sky axis sleeve and is inserted into the door frame sleeve, the front door panel is firmly connected to the overall door frame, ensuring the load-bearing capacity of the door. The hexagonal pull rod screw is rotated to cause the displacement, so that the connected sky axis pin extends upward and is inserted into the door frame sleeve on the overall door frame. The sky axis pin serves as the upper rotation center of the manual radiation-proof door leaf. At the same time, the self-locking of the inner rotating hexagonal pull rod screw can ensure that the sky axis pin does not fall. The tapered roller bearing can withstand axial and radial forces well, so that the rotational friction is greatly reduced when the radiation-proof door leaf is opened and closed.

[0018] The interior of the front door panel is equipped with a radiation protection structure composed of aluminum honeycomb and lead plate. The aluminum honeycomb has good sound insulation and heat insulation properties, and can also reduce the weight of the door. The lead plate is a highly efficient radiation protection material that can effectively block radiation penetration. The aluminum honeycomb is located between the front door panel and the lead plate, which supports and fixes the lead plate, while enhancing the overall strength of the door.

[0019] A radiation detector is installed on the top inner wall of the integral door frame, which can monitor the radiation level of the surrounding environment in real time. When the radiation level exceeds the safety threshold, the radiation detector will sound an alarm to remind medical staff and patients to take corresponding protective measures. Fixing holes are opened on the inner walls on all four sides of the integral door frame to facilitate fixing to the wall.

[0020] Beneficial effects:

[0021] In the utility model, the manual medical radiation-proof door realizes stable load-bearing and convenient opening and closing of the radiation-proof door through the cooperation of the first connecting component and the second connecting component, thereby improving the use efficiency;
