[0028] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to be able to fully convey the scope of the present disclosure to those skilled in the art. It should be noted that, in the absence of conflict, the embodiments of the present invention and the features described in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] See also Figure 1 and Figure 2 , the figure shows the preferred structure of the shielding cabin provided by the embodiment of the present invention. As shown in the figure, the composite shielding device 3 is used to detect patients, and the composite shielding device 3 is movable, so that the composite shielding device 3 can be moved to different positions. The shielding cabin is arranged on one side of the composite shielding device 3, and the shielding cabin blocks the input port of the composite shielding device 3 to play a role in shielding external electromagnetic interference. The supporting device 10 is also arranged on one side of the composite shielding device 3 and supports the shielding cabin. The supporting device 10 can be a supporting bed or other devices, and this embodiment does not impose any restrictions on this. In specific implementation, the supporting device 10 can be a control cabinet.

[0030] As shown in the figure, the shielding cabin includes: a shielding cover 1 and a bottom plate 2. The bottom plate 2 is arranged on the supporting device 10. Specifically, the bottom plate 2 is arranged on the upper part of the control cabinet (relative to the Figure 1 The interior of the shielding cover 1 is hollow, and the bottom of the shielding cover 1 ( Figure 3 The bottom of the shielding cover 1 is slidably connected to the bottom plate 2, so that the shielding cover 1 can slide relative to the bottom plate 2, thereby allowing the shielding cover 1 to slide toward the composite shielding device 3 or slide away from the composite shielding device 3. The side of the shielding cover 1 facing the composite shielding device 3 ( Figure 3 The left side of the shielding cover 1 is an open end, and the open end of the shielding cover 1 is connected to the composite shielding device 3, and the open end of the shielding cover 1 corresponds to the input port of the composite shielding device 3 to block the input port of the composite shielding device 3. The side of the shielding cover 1 away from the composite shielding device 3 ( Figure 3The right side shown is a closed end, so that after the shielding cover 1 and the composite shielding device 3 are connected, the shielding cabin is in a closed state as a whole.

[0031] The bottom plate 2 is used to seal the bottom of the shielding cover 1, carry the patient, and shield the bottom of the shielding cover 1. When the shielding cover 1 blocks the input port of the composite shielding device 3, the patient is placed inside the composite shielding device 3 and the shielding cover 1 to prevent the patient from being exposed.

[0032] The shielding cover 1 and the bottom plate 2 are both made of conductive materials, so that the shielding cabin is conductive as a whole, thereby ensuring the normal operation of the shielding cabin.

[0033] In specific use, when the staff needs to operate on the patient, the shielding cover 1 can be slid away from the composite shielding device 3 to expose the patient. Alternatively, when the patient is tested, the shielding cover 1 can be slid away from the composite shielding device 3 to facilitate the patient to get off from the bottom plate 2.

[0034] It can be seen that in the present embodiment, the shielding cover 1 can slide toward the composite shielding device 3 and connect with the composite shielding device 3, and the input port of the composite shielding device 3 is blocked by the shielding cover 1, so that the shielding cover 1 and the composite shielding device 3 as a whole form a closed space to accommodate the patient. In this way, when the patient is undergoing detection, the shielding cover 1 can effectively shield the interference of external signals on the detection, avoid the influence of external interference on the detection result, and improve the accuracy of the detection. In addition, the setting of the shielding cover 1 can ensure that the composite shielding device 3 can be moved to the required position according to the needs of the patient without the need to move the patient, thereby solving the problem that the movable detection device in the prior art cannot shield external interference. In addition, the shielding cover 1 can slide relative to the bottom plate 2, thereby improving the overall flexibility of the shielding cabin, facilitating the movement of the patient and the operation of the patient by the staff, and improving the convenience of the staff's operation.

[0035] join Figures 1 to 4 In the above embodiment, the shielding cover 1 may include: a frame 11, a shielding door 12 and a plurality of shielding plates 13. The frame 11 is a hollow structure as a whole and is arranged in a skeleton. Each shielding plate 13 is arranged on the frame 11 to close the frame 11 and play a shielding role. Specifically, each shielding plate 13 may be arranged on the outside of the frame 11, or may be arranged on the inside of the frame 11, or each shielding plate 13 may be embedded in the frame 11, and this embodiment does not impose any limitation on this.

[0036] Preferably, each shielding plate 13 is detachably connected to the frame 11 , such as by screws.

[0037] The bottom of the frame 11 ( Figure 3 The lower part shown) and the two opposite side parts ( Figure 3The left and right sides shown in the figure are both open ends, so the frame 11 is U-shaped as a whole. The bottom of the frame 11 is slidably connected to the bottom plate 2, and the first side ( Figure 3 The left side of the frame 11 is connected to the composite shielding device 3, and the first side of the frame 11 corresponds to the input port of the composite shielding device 3 to block the input port of the composite shielding device 3. Figure 3 The right side of the frame 11 is rotatably connected to the shielding door 12, that is, the shielding door 12 can cover or open the second side of the frame 11, so that the second side of the frame 11 can be in a closed state or an open state.

[0038] The frame 11, the shielding door 12 and the shielding plates 13 are all made of conductive materials. Among them, the frame 11 can be made of metal conductive materials spliced ​​or welded. In specific implementation, the metal frame is heavy and inconvenient to move. It can be made of lightweight materials with a conductive layer to reduce the weight of the frame 11 and reduce the resistance when the frame 11 slides with the bottom plate 2. In specific implementation, the shielding plate 13 can be made of conductive metal plates, such as copper plates, stainless steel plates, galvanized steel plates, etc.

[0039] Each shielding plate 13 may be an opaque structure or a transparent structure, and this embodiment does not impose any restrictions on this. Preferably, each shielding plate 13 is a transparent structure to facilitate staff to observe the patient. Specifically, each shielding plate 13 is a composite plate structure, see Figure 5 , each shielding plate 13 may include: at least two layers of transparent plates 131 and at least one layer of metal mesh 132. Each layer of metal mesh 132 is sandwiched between two layers of transparent plates 131, and each layer of transparent plates 131 and each layer of metal mesh 132 are alternately overlapped. Specifically, each layer of transparent plates 131 and each layer of metal mesh 132 are arranged as follows: one layer of transparent plate 131 and one layer of metal mesh 132, which are arranged alternately in a cycle, and the two outermost layers of each shielding plate 13 are transparent plates 131 respectively. In specific implementation, each layer of transparent plate 131 can be made of glass plate or organic glass plate, and metal mesh 132 can be made of stainless steel mesh or copper mesh. In specific implementation, the number of layers of transparent plate 131 and metal mesh 132 is determined according to the shielding effect to be achieved.

[0040] It can be seen that in the present embodiment, the frame 11 acts as a skeleton, and each shielding plate 13 is arranged on the frame 11 so that the frame 11 is in a closed state as a whole, thereby effectively shielding external interference. The shielding door 12 is rotatably connected to the frame 11, which is convenient for opening or closing the shielding door 12. When the shielding door 12 is opened, it is convenient for transferring the patient to the bottom plate 2, especially for patients who cannot move, which greatly improves the comfort of the patients. When the shielding door 12 is closed, the overall shielding performance of the shielding cover 1 is effectively improved, thereby avoiding interference from external electromagnetic signals.

[0041] See also Figure 6 and Figure 7 In the above embodiments, a guide rail is provided between the bottom plate 2 and the bottom of the shielding cover 1, and the bottom of the shielding cover 1 and the bottom plate 2 are slidably connected via the guide rail.

[0042] The guide rail may include: two guide rail components. The two guide rail components correspond to the bottoms of the two opposite sides of the shielding cover 1. Specifically, since the inside of the shielding cover 1 is hollow and the bottom is open, the bottom of the shielding cover 1 is the opposite sides of the shielding cover 1 (at Figure 1 As shown in the bottom of the shielding cover 1 (both sides of the shielding cover 1 in the direction perpendicular to the paper), the bottom of one side of the shielding cover 1 corresponds to a guide rail assembly, and the bottom of the other side of the shielding cover 1 corresponds to another guide rail assembly, and the two guide rail assemblies are arranged in parallel.

[0043] See also Figure 4 , Figure 6 and Figure 7 Each guide rail assembly may include: a track 4 and a slider 5. The slider 5 is detachably arranged at the bottom of the corresponding side of the shielding cover 1. The length of the slider 5 matches the length of the shielding cover 1. The slider 5 is arranged along the length direction of the shielding cover 1 ( Figure 3 The bottom of track 4 ( Figure 7 The lower part) is detachably arranged on the bottom plate 2, and the length of the track 4 matches the length of the bottom plate 2. The track 4 is along the length direction of the bottom plate 2 ( Figure 1 The top of track 4 ( Figure 7 The upper portion is provided with a groove 41 along its length direction, and the slider 5 is slidably placed in the groove 41. The sliding of the slider 5 in the groove 41 drives the shielding cover 1 to slide relative to the bottom plate 2.

[0044] See also Figure 4 and Figure 6 , the top of slider 5 ( Figure 4 The upper part) is detachably connected to the bottom of the corresponding side of the shielding cover 1. Preferably, the top of the slider 5 is provided with a Figure 4The bottom of the corresponding side of the shielding cover 1 is accommodated in the accommodating groove, and the shielding cover 1 is detachably connected to the slider 5. The detachable connection is preferably a screw connection. Of course, it can also be other ways. This embodiment does not impose any restrictions on this.

[0045] See also Figure 4 and Figure 6 Preferably, a first conductive pad 7 is provided at the contact point between the bottom of the corresponding side of the shielding cover 1 and the side wall of the accommodating groove.

[0046] In a specific implementation, the shielding plates 13 at the two opposite sides of the frame 11 in the shielding cover 1 are both arranged outside the frame 11, and the bottoms of the shielding plates 13 at the two opposite sides of the frame 11 correspond to the two guide rail assemblies one by one. The slider 5 is detachably connected to the shielding plates 13 at the corresponding sides of the frame 11. Specifically, the shielding plates 13 at the corresponding sides of the frame 11 are accommodated in the accommodating groove of the slider 5 and are screwed to the slider 5. The first conductive pads 7 are arranged at the contact points between the two side surfaces of the shielding plate 13 and the two side walls corresponding to the accommodating groove.

[0047] See also Figure 4 and Figure 6 , the bottom of slider 5 ( Figure 4 The lower part) is provided with a connecting portion 6 along its length direction, and the length of the connecting portion 6 is the same as the length of the slider 5. Both sides of the connecting portion 6 protrude from the slider 5 in the width direction, so the slider 5 and the connecting portion 6 form a structure with a convex cross-section. Figure 4 The direction perpendicular to the paper surface, the width direction is perpendicular to the length direction, and the width direction is Figure 4 From left to right (i.e. Figure 4 In the direction indicated by a in FIG, the distance of the connecting portion 6 in the width direction is greater than the distance of the slider 5 in the width direction.

[0048] See also Figure 6 and Figure 7 The bottom wall of the groove 41 is provided with a recessed portion 42, the length of the recessed portion 42 is the same as the length of the groove 41, and the two sides of the recessed portion 42 protrude from the groove 41 in the width direction, so the groove 41 and the recessed portion 42 form a structure with a "convex" shape in cross section. Figure 7 The direction perpendicular to the paper surface, the width direction is perpendicular to the length direction, and the width direction is Figure 7 From left to right (i.e. Figure 7 In the direction indicated by a in FIG. 1 , the distance of the recessed portion 42 in the width direction is greater than the distance of the groove 41 in the width direction.

[0049] The convex structure formed by the slider 5 and the connecting portion 6 matches the convex structure formed by the groove 41 and the recessed portion 42 . The connecting portion 6 is slidably disposed in the recessed portion 42 , and the slider 5 is inserted into the groove 41 .

[0050] Preferably, the detachable connection between the rail 4 and the base plate 2 is a bolt connection. Specifically, the bolts are passed through the bottom of the recessed portion 42 and are threadedly connected to the base plate 2 .

[0051] In specific implementation, the track 4 and the slider 5 are both made of conductive materials. In specific implementation, the track 4 and the slider 5 can be made of copper material, which has good conductivity on the one hand and can reduce the friction resistance of sliding when the track 4 and the slider 5 slide together on the other hand.

[0052] It can be seen that in this embodiment, two parallel tracks 4 are arranged on the bottom plate 2, and sliders 5 are arranged at the bottom of the opposite sides of the shielding cover 1. The two sliders 5 correspond to the two tracks 4 one by one and are slidably connected, thereby realizing the sliding between the shielding cover 1 and the bottom plate 2. The structure is simple and easy to implement.

[0053] See also Figure 8 and Fig. 9 In the above embodiments, the bottom plate 2 may include: a first connecting plate 21, a second connecting plate 22 and a supporting mechanism 23. The first connecting plate 21 is disposed on the supporting device 10, and the second connecting plate 22 is rotatably connected to the first connecting plate 21, so that the second connecting plate 22 can be flipped relative to the first connecting plate 21, that is, the second connecting plate 22 can be in a straight state with the first connecting plate 21 after rotation, or can be in a bent state with the first connecting plate 21 after rotation. In this embodiment, the second connecting plate 22 is perpendicular to the first connecting plate 21 after rotation and fits with the supporting device 10. Preferably, the second connecting plate 22 is connected to the first connecting plate 21 by a hinge.

[0054] The support mechanism 23 is disposed between the side wall of the support device 10 and the second connecting plate 22, and the support mechanism 23 is disposed obliquely, and the support mechanism 23 is used to support the second connecting plate 22 when the second connecting plate 22 and the first connecting plate 21 are in a straight state, so that the second connecting plate 22 and the first connecting plate 21 remain in a straight state. In a specific implementation, the support mechanism 23 can be a retractable structure, and when the second connecting plate 22 and the first connecting plate 21 are in a straight state, the support mechanism 23 is in an extended state and obliquely supports the second connecting plate 22; when the second connecting plate 22 and the first connecting plate 21 are turned over and are perpendicular, the support mechanism 23 is in a compressed state to retract the second connecting plate 22 and no longer supports the second connecting plate 22.

[0055] When the first connecting plate 21 and the second connecting plate 22 are in a straight state, the first connecting plate 21 and the second connecting plate 22 are both slidably connected to the bottom of the shielding cover 1. Specifically, the first connecting plate 21 and the second connecting plate 22 are both provided with tracks 4, and when the second connecting plate 22 and the first connecting plate 21 are in a straight state, the tracks 4 on the first connecting plate 21 and the tracks 4 on the second connecting plate 22 are connected and tightly matched, and the slider 5 on the shielding cover 1 can be slidably connected to the tracks 4 after the connection, so as to ensure the shielding between the shielding cover 1 and the bottom plate 2.

[0056] In a specific implementation, the first connecting plate 21, the second connecting plate 22 and the supporting mechanism 23 are all made of conductive materials. Figure 7 In order to reduce the weight of the bottom plate 2, the first connecting plate 21 is made of a highly lightweight material, and the first connecting plate 21 is coated with a conductive layer 24. The track 4 is fixedly connected to the first connecting plate 21 by bolts, and the track 4 and the conductive layer 24 are tightly crimped.

[0057] It can be seen that in this embodiment, the second connecting plate 22 can be flipped relative to the first connecting plate 21, so that during scanning and detection, the second connecting plate 22 and the first connecting plate 21 are in a straight state, ensuring the stability of the overall structure of the bottom plate 2. The shielding cabin can move with the composite shielding device 3. When the shielding cabin moves, the second connecting plate 22 can be flipped to a bent state with the first connecting plate 21, reducing the overall size during movement. In addition, when moving, the shielding cover 1 can be removed from the bottom plate 2, and the shielding cover 1 can be moved alone, which improves the convenience during movement.

[0058] See also Fig.10 and Fig.11 In the above embodiments, the shielding cabin may further include: a docking device 8. The docking device 8 is made of a conductive material and is used to make the shielding cover 1 and the composite shielding device 3 closely contact each other to achieve conductive connection and shielding between the composite shielding device 3 and the shielding cover 1.

[0059] The docking device 8 may include: a docking frame 81 and a conductive connector 82. The docking frame 81 and the conductive connector 82 are both semi-annular, specifically U-shaped. The docking frame 81 is arranged at the input port of the composite shielding device 3, and the docking frame 81 is detachably connected to the composite shielding device 3. Specifically, the docking frame 81 matches the shape of the input port of the composite shielding device 3. The docking frame 81 only corresponds to the top and two sides of the input port of the composite shielding device 3, and the opening of the docking frame 81 faces the bottom plate 2. Preferably, the docking frame 81 is bolted to the composite shielding device 3 to facilitate installation and disassembly.

[0060] Preferably, a second conductive pad 9 is provided at the contact point between the docking frame 81 and the composite shielding device 3 to ensure a tight connection between the docking frame 81 and the composite shielding device 3 and to improve its conductivity. The second conductive pad 9 has a preset flexibility, which can be determined according to actual conditions, and the present embodiment does not impose any restrictions on this. In specific implementation, the second conductive pad 9 can be a metal conductive mesh or a conductive foam, or other materials, and the present embodiment does not impose any restrictions on this. In specific implementation, when the docking frame 81 is bolted to the composite shielding device 3, the bolts penetrate the composite shielding device 3 and the second conductive pad 9 and are screwed to the docking frame 81.

[0061] The shape of the conductive connector 82 matches the shape of the docking frame 81, and the conductive connector 82 has a preset flexibility so that the conductive connector 82 has a certain flexibility. The conductive connector 82 is embedded in the side of the docking frame 81 facing the shielding cover 1. Specifically, the conductive connector 82 is partially placed in the docking frame 81, and partially placed outside the docking frame 81 and in close contact with the frame 11 of the shielding cover 1 to ensure its conductivity.

[0062] In specific implementation, the conductive connector 82 can be made of conductive foam, conductive brush, etc., or other materials, and this embodiment does not impose any restrictions on this. The docking frame 81 is made of conductive material, specifically, the docking frame 81 can be made of conductive metal material. In order to reduce weight, the docking frame 81 can be made of lightweight non-metallic material and wrapped with a thin layer of conductive material.

[0063] It can be seen that in this embodiment, the docking device 8 can ensure tight docking between the shielding cover 1 and the composite shielding device 3, thereby improving the shielding performance between the shielding cover 1 and the composite shielding device 3. The docking device 8 has a simple structure and is easy to implement.

[0064] To sum up, in this embodiment, the input port of the composite shielding device 3 is blocked by the shielding cover 1, so that the shielding cover 1 and the composite shielding device 3 as a whole form a closed space to accommodate the patient. In this way, when the patient is undergoing testing, the shielding cover 1 can effectively shield the interference of external signals on the detection, avoid the influence of external interference on the detection result, and improve the accuracy of the detection. In addition, the shielding cover 1 can ensure that the composite shielding device 3 can be moved to the required position according to the needs of the patient without the need to move the patient. In addition, the shielding cover 1 can slide relative to the bottom plate 2, thereby improving the overall flexibility of the shielding cabin, facilitating the movement of the patient and the operation of the patient by the staff, and improving the convenience of the staff's operation.

[0065] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
