Abstract
Description
Technical Field
[0001] This utility model relates to the field of radiation shielding door technology (lead plate), specifically to profile structure for shielded rooms, where the shielded room can be understood as an inspection room, laboratory, or other place where radiation equipment is placed. Background Technology
[0002] Examination rooms equipped with CT, MIR, DR, and other radiological equipment have radiation-shielding panels on their walls and lead-plate radiation-shielding doors at the entrances and exits to prevent radiation leakage and harm to personnel. This makes the examination room a shielded room that prevents radiation leakage. Existing lead-plate radiation-shielding doors installed in shielded rooms include a door frame, a honeycomb panel, a lead plate, a pressure plate, and two panels covering both sides of the door frame. The honeycomb panel contacts the inner end face of panel one and is fixed together with a special adhesive. The lead plate is fixedly clamped between the honeycomb panel and the pressure plate, keeping it fixed relative to the door frame. The honeycomb panel provides support for one end face of the lead plate, and a special adhesive is applied between the pressure plate and the other end face of the lead plate to ensure a firm bond. See the patent document CN216894100U, entitled "A Radiation-Supported Sliding Door with Aluminum Honeycomb Panel," for more information on this technology.
[0003] Because the lead plate is thick and heavy, the adhesive between the pressure plate and the lead plate will become weaker after long-term operation, and the lead plate will inevitably sink, which will negatively affect the protective performance of the radiation-proof lead plate door. Utility Model Content
[0004] To overcome the problem that the bond between the pressure plate and the lead plate will significantly deteriorate after long-term operation, which may lead plate sinking, this utility model provides a profile structure for shielded rooms. By improving the end face structure of the pressure plate, it helps to improve the firmness of the pressure plate in fixing the lead plate, thereby effectively suppressing the sinking of the lead plate.
[0005] The technical solution adopted by this utility model to solve its technical problem is: the profile structure for shielded rooms includes lead plates and pressure plates for contact matching.
[0006] On the pressure plate, multiple grooves are formed on the end face facing the lead plate, and these grooves are distributed near the lower edge of the pressure plate. An elastic pressure arm is formed on the inner bottom surface of each groove, with the ends of the elastic pressure arms extending beyond the opening of the groove. An elastic deformation portion is formed at the root of each elastic pressure arm.
[0007] When the pressure plate and the lead plate are in contact, the elastic deformation part can cause the elastic pressure arm to undergo elastic deformation from its root, so that the end can establish a surface contact matching relationship with the lead plate.
[0008] Optionally, multiple layers of grooves are provided alternately in the vertical direction near the upper and lower edges of the pressure plate.
[0009] The number of grooves located near the upper edge of the pressure plate is greater than the number of grooves located near the lower edge of the pressure plate.
[0010] Each layer contains multiple grooves arranged horizontally in alternating patterns.
[0011] Optionally, a door frame is also included. The pressure plate is fixed to the door frame by multiple studs, so that the pressure plate can press the lead plate into the door frame and keep it fixed relative to the door frame.
[0012] Optionally, it also includes a second panel that is detachably fixed to the door frame.
[0013] Multiple vertically spaced protruding ridges are formed on the end face of panel two facing the pressure plate. Correspondingly, multiple grooves are formed on the end face of the pressure plate facing panel two, each corresponding to one of the protruding ridges.
[0014] The protruding ridge is inserted into the second groove, and a surface contact matching relationship can be formed between the two opposite surfaces.
[0015] The beneficial effects of this utility model are: by improving the end face structure of the pressure plate, this utility model helps to improve the firmness and stability of the pressure plate in fixing the lead plate, helps to suppress the sinking of the lead plate, or can significantly prolong the time before the lead plate shows significant sinking, and helps to keep the protective performance of the radiation-proof lead plate door stable and reliable.

[0020] The structures, proportions, and sizes shown in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art. They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, terms such as "upper," "lower," "front," "rear," and "middle" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.
[0021] like Figures 1 to 3 The profile structure (or profile panel assembly for shielded rooms) shown includes a panel 10 fixed to one side of a door frame 20, a honeycomb panel 30 fixedly attached to the inner end face of the panel 10, a lead plate 40 that contacts and matches the honeycomb panel 30, a pressure plate 50 that is fixed to the door frame 20 by a plurality of studs and contacts and matches the lead plate 40, and a panel 60 that is detachably fixed to the other end face of the door frame 20.
[0022] On the pressure plate 50, a plurality of grooves 51 are formed on its end face facing the lead plate 40, and the grooves 51 are distributed near the upper and lower edges of the pressure plate 50. An elastic pressure arm 52 is formed on the inner bottom surface of each groove 51, and the ends 521 of the elastic pressure arms 52 extend beyond the openings of the grooves 51. An elastic deformation portion 522 is formed at the root of each elastic pressure arm 52.
[0023] The groove 51 can be a straight groove, and its length extends in the lateral direction.
[0024] When the pressure plate 50 is pressed into contact with the lead plate 40, the elastic deformation part 522 can cause the elastic pressure arm 52 to undergo elastic deformation from its root, so that the end 521 can establish a surface contact matching relationship with the surface of the lead plate 40.
[0025] In the above solution, the elastic pressure arm 52 can apply elastic pressure to the lead plate 40, thereby establishing a stable contact between the two and improving the fixing firmness of the pressure plate 50 to the lead plate 40, suppressing the sinking of the lead plate 40, and helping to keep the protective performance of the radiation-proof lead plate door stable and reliable.
[0026] To improve the effect of the pressure plate 50 in pressing the lead plate 40 and enhance stability and reliability, multiple layers of grooves 51 are alternately provided in the vertical direction near the upper and lower edges of the pressure plate 50. Preferably, the number of grooves 51 near the upper edge of the pressure plate 50 is greater than the number of grooves 51 near the lower edge of the pressure plate 50.
[0027] To allow the elastic pressure arm 52 to deform sufficiently and for its end 521 to form a large contact surface with the lead plate 40, the lateral extension length of the elastic pressure arm 52 can be reduced. This can be achieved by including multiple laterally alternating grooves 51 in each layer, thereby reducing the lateral span of the elastic pressure arm 52. Figure 3 In the illustrated scheme, each layer has two grooves 51. Preferably, the concave surface of the elastic pressure arm 52 faces upward, which helps to improve the state / direction of the pressing force applied by the elastic pressure arm 52 on the lead plate 40, improve the pressing effect, and enhance the stability of the lead plate 40 under pressure.
[0028] Multiple vertically spaced protruding ridges 61 are formed on the end face of the second panel 60 facing the pressure plate 50; correspondingly, multiple grooves 53 are formed on the end face of the pressure plate 50 facing the second panel 60, each corresponding to one of the protruding ridges 61. The protruding ridges 61 are inserted into the grooves 53, and a surface contact matching relationship is formed between their opposing surfaces. In this way, after the second panel 60 and the door frame 20 are fixedly connected together by bolts or studs, and the protruding ridges 61 are directly matched with the pressure plate 50 through a mechanical structure, the connection between the pressure plate 50 and the door frame 20 can be significantly improved in terms of firmness and stability. This helps to improve the pressing and fixing effect of the pressure plate 50 on the lead plate 40, and both stability and reliability can be improved. Special adhesive can still be applied between the main contact surfaces of the pressure plate 50 and the lead plate 40.
[0029] like Figure 1 As shown, panel 10 is fixed to the other end face of the door frame 20, facing panel 2. The honeycomb panel 30 matches the inner end face of panel 10 and is bonded together as a whole using a special adhesive. The end face of the lead plate 40 facing away from the pressure plate 50 contacts and matches the honeycomb panel 30; a special adhesive can be applied to bond their opposing surfaces together. The honeycomb panel 30 helps achieve a lightweight design for the product (door).
[0030] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit it. Many aspects of this utility model can be improved without departing from the overall concept. Those skilled in the art can modify or change the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or changes made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
