Description

Technical Field

[0001] This utility model relates to the field of radiation protection door technology, specifically to a sliding radiation protection door with anti-collision strips. Background Technology

[0002] Sliding radiation shielding doors (also known as sliding lead doors) are high-security doors that open and close by horizontal sliding. They are widely used in scenarios with high requirements for protection levels, airtightness, and space utilization, and are standard equipment in CT and DR rooms. Most existing sliding radiation shielding doors use 99.9% pure lead plates as the core protective layer, with the lead equivalent customized according to requirements (e.g., 2-5 mmPb for medical X-ray rooms). The door leaf is filled with fire-resistant honeycomb paper core boards, and the surface is covered with galvanized steel or stainless steel, providing both impact resistance and fire resistance. The sliding movement is driven by a DC brushless servo motor (such as the MA-HG series), combined with aluminum alloy or high-strength steel guide rails, and an auxiliary roller design (for heights > 4000mm) to ensure smooth operation. EPDM sealing strips are embedded on three sides of the door frame, and some high-end models use an automatic lifting sweeping strip that presses against the ground when closed, reducing air leakage.

[0003] Sliding radiation shielding doors are mainly divided into two types: single-leaf and double-leaf. Single-leaf sliding radiation shielding doors are high-security doors specifically designed for high-radiation environments, opening and closing through horizontal sliding. The main problem with existing single-leaf sliding radiation shielding doors is that a strong impact can easily occur between the door and the frame when closing. This not only negatively affects the sealing performance but also easily causes the lead plates inside the door to move, affecting its radiation shielding performance and causing excessive radiation leakage, thus posing a safety hazard. Utility Model Content

[0004] The sliding radiation shielding door with anti-collision strips provided by this utility model can reduce the impact intensity between the door and the frame when closing, which helps to ensure the stability and reliability of the fixed position of the lead plate inside the door.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a sliding radiation-proof door with anti-collision strips, including a radiation-proof door body, a track matching the radiation-proof door body, a door frame fixed to the wall and matching the radiation-proof door body, and an anti-collision strip assembly. The anti-collision strip assembly includes a frame fixedly connected to the door frame and a bladder fixedly disposed on the frame.

[0006] The bladder is filled with air, and multiple vertically spaced bulges are formed on the side of the bladder facing the radiation shield. The outer surfaces of these bulges are all curved. The vertically spaced bulges create a wavy, undulating bladder wall on the outer end face, providing excellent elastic shock absorption.

[0007] Optionally, an edge strip is formed at the edge of the capsule, and a edging structure is formed at the edge of the frame, with the edge strip extending into the edging structure and fixed together with the frame.

[0008] Optionally, an elastic pad is fixedly provided on the outer end face of the edging structure. The apex of the raised portion protrudes outward relative to the outer end face of the elastic pad.

[0009] Optionally, the outer side of the elastic pad is formed as a slope extending in the vertical direction, with the outer end of the slope facing away from the frame relative to the inner end.

[0010] Optionally, an edge plate is formed at the edge of the frame and the edge plate is fixed to the door frame.

[0011] Optionally, it also includes an air pump unit and a control unit. The air pump unit is matched with the bladder body and can selectively inflate and depress air into the bladder cavity. The control unit is matched with the air pump unit and can control the inflation and deflation (i.e., inflation and depressurization) actions of the air pump unit. At that time, the bulge formed on the side of the bladder body facing the radiation shielding door will gradually increase in amplitude as the amount of air injected increases after sufficient air is inflated into the bladder cavity, but will still retain a certain elastic expansion and contraction margin, so that it can easily undergo elastic deformation when compressed, forming a buffer / shock-absorbing bladder structure.

[0012] An arm plate extending laterally inward is formed at the upper and / or lower edge of the frame. A limit switch, which is connected to the control unit and can control the inflation and deflation actions of the air pump unit, is fixed on the arm plate.

[0013] The radiation shielding door can simultaneously contact the limit switch and the protruding tip of the raised part, and the control unit can immediately control the air pump unit to gradually extract the air from the bag, so that the protrusion of the raised part gradually decreases while maintaining contact with the radiation shielding door.

[0014] This utility model also relates to a sliding radiation shielding door with anti-collision strips. Compared to the aforementioned sliding radiation shielding door, its difference lies in the fact that multiple raised portions are formed alternately in the front-to-back direction on the end face of the bladder facing the radiation shielding door body, and the length of the raised portions extends vertically. It should be emphasized that this type of sliding radiation shielding door can also be equipped with technical features such as an air pump unit, control unit, and limit switches.

[0015] The beneficial effects of this utility model are: when the sliding radiation shielding door is closed, the impact intensity between the door body and the frame is significantly reduced, thereby reducing the impact on the door body and helping to ensure the stability and reliability of the fixed position of the lead plate inside the door, so that the sliding radiation shielding door maintains good radiation protection and safety.

Detailed Implementation

[0021] 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.

[0022] like Figures 1 to 4 The illustrated sliding radiation shielding door with anti-collision strips includes a radiation shielding door body 10, a slide rail 20 matching the radiation shielding door body 10, and a door frame 30 fixed to a wall 100 and matching the radiation shielding door body 10. The slide rail 20 guides the radiation shielding door body 10 to slide horizontally, thereby blocking or opening the doorway. The foregoing technical content can be found in existing technology and, since it is not part of the technical innovation of this application, will not be elaborated further.

[0023] This application also includes a crash barrier assembly 40, which includes a frame 41 fixedly connected to the door frame 30 and a bladder 42 fixedly mounted on the frame 41. (See figure...) Figure 1As shown, the radiation-proof door 10 slides in the left-right direction. Sliding to the left gradually opens the doorway, while sliding to the right gradually closes it. Correspondingly, the anti-collision strip assembly 40 needs to be fixed to the right side plate of the door frame 30, with the length of the anti-collision strip assembly 40 extending vertically and the width extending front-back. A recessed groove for accommodating the frame 41 can be provided on the door frame 30, with the outer end face of the frame 41 flush with the groove opening. The bladder 42 is fixed inside the frame 41 and protrudes outward relative to the outer end face of the frame 41.

[0024] An air pump unit and a control unit that are associated with and matched with the bladder 42 can be set simultaneously. It should be noted that when the air pump unit and control unit are not set, the cavity of the bladder 42 is pre-filled with a certain amount of air, and this part of the air can always remain in the bladder 42 during normal use.

[0025] The air pump unit is matched with the bladder 42 and can selectively inflate and depress air into the cavity of the bladder 42. An inflation / deflation port 421 is provided on the right side of the bladder 42 and is connected to the air pump in the air pump unit via a pipe. This allows air to be inflated into the cavity of the bladder 42, causing the bladder 42 to expand, gradually increasing the thickness of its outer side (left side) protruding beyond the frame 41 to form a cushioning pad. Conversely, air is depressed from the cavity of the bladder 42, causing the bladder 42 to gradually shrink, gradually reducing the thickness of its outer side protruding beyond the frame 41, ultimately returning to its initial state.

[0026] The control unit is matched with the air pump unit and can control the air pump unit's inflation and deflation actions.

[0027] The main body of the control unit and the air pump unit can be located on the periphery of the radiation-proof door 10, door frame 30, etc., so that they do not need to be embedded in the wall 100.

[0028] On the left end face of the bladder 42 facing the radiation shielding door 10, and when sufficient air is filled into the cavity of the bladder 42, raised portions 422 are formed in alternating vertical directions. That is, when sufficient air is filled into the cavity of the bladder 42, the left end face of the bladder 42 can gradually protrude and form a wavy bladder wall surface with gradually increasing protrusion amplitude. It should be noted that, even without an air pump unit, after air is pre-filled into the left side of the bladder 42, multiple vertically spaced protrusions 422 can be formed. When these protrusions 422 are squeezed by the radiation shielding door 10, they can undergo elastic deformation, reducing the protrusion amplitude. Ultimately, the entire protruding surface of the bladder 42 can fully contact the right end face of the radiation shielding door 10. The elastic deformation of the bladder 42 can buffer the impact on the radiation shielding door 10 when it is closed, making the impact relatively mild.

[0029] Figures 1 to 4 The length of the raised portion 422 shown extends in the front-to-back direction, forming a front-to-back extending protrusion structure. In a specific implementation, the length of the raised portion 422 can also extend in the vertical direction, in which case the multiple raised portions 422 are distributed alternately in the front-to-back direction.

[0030] like Figure 4 As shown, arm plates 413 extending laterally inward (to the left) are formed at both the upper and lower edges of the frame 41. Limit switches 414, connected to the control unit and capable of controlling the inflation and deflation actions of the air pump unit, are fixedly mounted on the arm plates 413. The following configuration can be made: when the radiation shielding door 10 contacts the limit switch 414, the right end face of the radiation shielding door 10 can simultaneously contact the outer protruding tip of the bulge 422 (in a fully inflated state). That is, when the radiation shielding door 10 moves to the right, it can simultaneously contact the limit switch 414 and the outer protruding tip of the bulge 422. Therefore, at the instant the limit switch 414 is triggered, the control unit can immediately control the air pump unit to gradually... By gradually extracting the air from the bladder 42, the protrusion of the raised portion 422 gradually decreases. While the radiation shielding door 10 remains in contact with the bladder 42 / raised portion 422, the protrusion of the raised portion 422 gradually decreases / retracts, allowing the right end face of the radiation shielding door 10 to gradually press against the raised surface of the bladder 42. This makes the entire mating and pressing action smoother and reduces the impact intensity on the radiation shielding door 10.

[0031] An edge strip 423 is formed at the edge of the bladder 42, and a corresponding edging structure is formed at the edge of the frame 41. The edge strip 423 extends into the edging structure and is fixed together with the frame 41, so that the bladder 42 and the frame 41 are connected as a whole, making it less likely to fall off the frame 41 due to elastic tension when the bladder 42 is inflated.

[0032] An elastic pad 411 is fixedly provided on the outer end face of the edging structure. The raised portion 422, when fully inflated / protruding, can protrude / project outward relative to the outer end face of the elastic pad 411. (See attached image.) Figure 2 Thus, when the radiation shielding door 10 moves in the direction close to the bladder 42 (i.e., along...), Figure 1 When moving in the direction of velocity V (as shown), it can first contact the raised portion 422, and as the protrusion of the raised portion 422 gradually decreases, it approaches and eventually contacts the elastic pad 411, thus forming a good seal on the right end face of the radiation shielding door 10. To improve the contact between the radiation shielding door 10 and the elastic pad 411, the outer surface of the elastic pad 411 can be formed as a slope extending in the vertical direction, and the outer end of the slope can be further away from the frame 41 than the inner end.

[0033] An edge plate 412 is formed at the edge of the frame 41 and the edge plate 412 is fixed together with the door frame 30, thereby fixing the frame 41 or the anti-collision strip assembly 40 to the door frame 30 as a whole.

[0034] 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.
