Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic resonance, and particularly relates to a cable housing for ground wiring of an MR system and a magnetic resonance system. Background Art

[0002] The cables of traditional MRI (Magnetic Resonance Imaging) systems are laid out upward from the upper left rear direction of the MR (Magnetic Resonance) system and connected to external devices through the ceiling of the scanning room. The cables of the new type of "zero liquid helium" MR system can be laid out either upward or downward. When the cables of the "zero liquid helium" MR system are laid out upward, it is the same as that of the traditional MR system, that is, they are laid out upward and then connected to external devices through the ceiling of the scanning room. Currently, when the cables of the "zero liquid helium" MR system are laid out downward, the cables are completely laid under the ground, and no trace of wiring can be seen from the outside of the system.

[0003] However, since the MR system has various specifications of cables, the softness and hardness of the cables and their minimum bending radii are different. In order to avoid the continuous stress on the final shielding room floor caused by the bending degree of the underground cables, it is required that the floor of the shielding room can be constructed to a depth that can meet the maximum wire diameter and the maximum bending radius of the cables. Therefore, when the shielding room is existing or on a high floor, to achieve underground wiring, the shielding room needs to be renovated, resulting in increased costs; for some sites, due to the limited room height and the ground thickness not meeting the minimum thickness required for underground wiring, it is impossible to achieve underground wiring. Therefore, the above problems can be avoided by implementing above-ground wiring. A wire groove is set on the ground for wiring. In order not to interfere with normal work, the structure of the wire groove is designed to be relatively compact. The wire groove structure is damaged or pushed open due to the large acting force generated by the bending of the cables and the deformation of the helium pipes after wiring. At the same time, since the cables are laid on the ground, it is also necessary to prevent liquid from entering the wire groove and causing potential safety hazards. Summary of the Utility Model

[0004] In view of the above disadvantages of the prior art, the purpose of the present utility model is to provide a cable housing for ground wiring of an MR system and a magnetic resonance system, so as to improve the problem that the wire groove structure is damaged or pushed open due to the large acting force generated by the bending of the cables and the deformation of the helium pipes after wiring, and to solve the problem of potential safety hazards caused by liquid entering the wire groove.

[0030] The following uses specific specific examples to illustrate the implementation manners of the present utility model. Those skilled in the art can easily understand other advantages and effects of the present utility model from the content disclosed in this specification. The present utility model can also be implemented or applied through other different specific implementation manners. Various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present utility model.

[0031] It should be noted that the illustrations provided in this embodiment only schematically illustrate the basic concept of the present utility model. Therefore, only the components related to the present utility model are shown in the drawings, rather than being drawn according to the number, shape, and size of the components during actual implementation. The types, quantities, and proportions of the components during actual implementation can be arbitrarily changed, and the component layout type may also be more complex.

[0032] Please refer to Figures 1 to 4 As shown, the present utility model provides a cable housing and a magnetic resonance system for ground wiring of an MR system, aiming to solve the problems that when wiring on the ground, the cable housing used to protect and accommodate cables is damaged or pushed open due to the large force generated by the bending of the cables and the deformation of the helium pipes after wiring, and to solve the problems such as potential safety hazards caused by liquid entering the wire groove due to being arranged on the ground. Specifically, the cable housing 100 includes a base 10 and an upper cover 20. The base 10 is installed on the ground of the shielding room or partially located under the ground of the shielding room. The upper cover 20 covers the base 10 to form a receiving space for accommodating the cables of the magnetic resonance equipment. The upper cover 20 and the base 10 are snap-fitted and fixed through a snap structure.

[0033] Please refer to Figure 1 、 Figure 3 and Figure 4 As shown, in this embodiment, the base 10 includes a bottom wall 11 and side walls 12 provided at opposite ends of the bottom wall 11 and erected upward. First buckles 13 are also provided on both sides of the bottom wall 11. The first buckles 13 are erected upward and located inside the side walls 12. Correspondingly, second buckles 21 are provided inside the side edges of the upper cover 20, and the second buckles 21 protrude toward the base 10. The second buckles 21 correspond to the first buckles 13 one by one. When the upper cover 20 is closed on the base 10, the second buckles 21 cooperate with the first buckles 13 inside the side walls 12 of the base 10 to be snap-connected, so as to snap-fix the base 10 and the upper cover 20 to form a receiving space for accommodating the cavity cable. In this embodiment, a guiding structure is further provided on the opposite surfaces of the first buckles 13 and the second buckles 21. For example, the guiding structure is an inclined surface 101, that is, the opposite surfaces of the first buckles 13 and the second buckles 21 are provided with inclined surfaces 101 with the same inclined direction. When the upper cover 20 is closed on the base 10, the second buckles 21 and the first buckles 13 can be accurately and conveniently snap-connected under the cooperation of their inclined surfaces 101, so as to realize the fixation of the upper cover 20 and the base 10.

[0034] It can be understood that since the base 10 is installed on the ground, in order to avoid interference of the cable housing 100 located on the ground during the working process. For example, if the cable housing 100 is too high, it will cause obstacles to the users during walking and affect the aesthetics. Therefore, in order to reduce the risk of tripping during, for example, the movement of personnel and for the overall aesthetics, in this embodiment, the overall height of the cable housing 100 is relatively low. Except for the housing wall of the housing, the height of the internal accommodation space is about 55 mm. Therefore, when helium pipes, gradient cables, etc. are arranged in the cable housing 100, due to the bending of the cables and the deformation of the helium pipes, a large force will be generated on the cable housing 100. Through the snap-connection cooperation between the first buckles 13 and the second buckles 21, it can be avoided that the upper cover 20 is pushed out under the action of the force generated by the cables, and it can serve the purpose of accommodating and restricting the cables, so as to realize the ground wiring. At the same time, the snap-connection method makes the appearance of the cable housing 100 beautiful and convenient for disassembly and assembly.

[0035] Please refer to Figure 1 、 Figure 3 and Figure 4As shown, in this embodiment, grooves 111 are provided on both sides of the bottom wall 11. The grooves 111 extend along the length direction of the base 10 and are located between the first buckle 13 and the side wall 12. When the first buckle 13 and the second buckle 21 are engaged in a snap fit, a part of the second buckle 21 extends into the groove 111. It can be understood that a sufficient spacing height needs to be reserved between the first buckle 13 and the bottom surface of the base 10 to facilitate the snap connection between the second buckle 21 and the first buckle 13. In this embodiment, by providing the grooves 111 on the bottom wall 11, the design of the grooves 111 can increase the gap between the first buckle 13 and the bottom surface of the base 10. At this time, this gap is the gap between the first buckle 13 and the bottom surface of the groove 111. Compared with the case where the first buckle 13 is directly provided on a plane, the overall height after the upper cover 20 and the base 10 are closed can be effectively reduced. At the same time, when the second buckle 21 is engaged with the first buckle 13, there is still a certain gap between the bottom of the second buckle 21 and the bottom surface of the groove 111, which can eliminate the assembly stress and is beneficial to the snap connection between the first buckle 13 and the second buckle 21.

[0036] Please refer to Figure 1 and Figure 2 As shown, in this embodiment, the cable housing 100 further includes a load support member 30. The load support member 30 is provided on the surface of the upper cover 20 facing the base 10 and is arranged on both sides of the upper cover 20 along the width direction. Among them, a plurality of the load support members 30 are arranged at intervals along the length direction of the upper cover 20 on each side. When the upper cover 20 is closed on the base 10, the load support member 30 supports on the surface of the bottom wall 11 to improve the structural strength and load support capacity of the cable housing 100. It can withstand a load of more than 350 kg and can avoid damage to the cable housing 100 caused by human trampling or other objects during use. Further, in this embodiment, the load support member 30 and the second buckle 21 are arranged at intervals along the length direction of the upper cover 20, that is, the snap structure between the upper cover 20 and the base 10 is spaced apart from the load support member 30, so that the load and the clamping force can be evenly distributed, improving the reliability of the cable housing 100.

[0037] Please refer to Figure 1 and Figure 2As shown, in this embodiment, along the width direction of the cable cover 100, a plurality of supporting partitions 102 are further provided on the upper cover 20 and / or the bottom wall 11, and the two ends of the supporting partitions 102 are respectively connected to the upper cover 20 and the bottom wall 11, and the supporting partitions 102 can separate the accommodating chamber formed between the upper cover 20 and the base 10 into a plurality of independent chambers, so as to accommodate different cables. Furthermore, the supporting partitions 102 can also play a role in supporting the load, thereby improving the load supporting capacity of the cable cover 100. Furthermore, in this embodiment, the cable cover 100 is made of ABS (Acrylonitrile Butadiene Styrene) and PC (Polycarbonate) composite materials, so that it has good comprehensive mechanical properties, better strength and toughness, thereby further ensuring the reliability and structural strength of the cable cover 100.

[0038] See also Figure 1 , Figure 3 and Figure 4 As shown, in the present embodiment, when the upper cover 20 is covered with the base 10, a gap 103 is formed between the top of the side wall 12 and the side of the upper cover 20 facing the base 10. For example, the range of the gap 103 is set to 0.5 mm to 1 mm. The existence of the gap 103 can eliminate the assembly stress between the upper cover 20 and the base 10, facilitate the assembly of the upper cover 20 and the base 10, and reduce the requirements for manufacturing accuracy. In addition, the gap 103 is connected to the interior of the cable cover 100, which is beneficial to air convection, thereby facilitating the heat dissipation of the cable.

[0039] See also Figure 1 , Figure 3 and Figure 4 As shown, in the present embodiment, the width of the upper cover 20 is greater than the width of the base 10. When the upper cover 20 is covered on the base 10, the side of the upper cover 20 protrudes outward in the width direction in an eaves-like manner relative to the side wall 12 of the base 10. The protruding portion 104 is similar to an eaves structure, so that the liquid can flow along the protruding portion 104 to the bottom surface to prevent the liquid from flowing into the interior of the cable cover 100. At the same time, when it is necessary to remove the upper cover 20, the upper cover 20 can be pried from the protruding portion 104 by tools or hands to release the buckle, thereby completing the disassembly, so that the upper cover 20 of the cable cover 100 can be easily removed; at the same time, the existence of the protruding portion 104 makes it unnecessary to align the sides of the upper cover 20 and the base 10, thereby reducing the manufacturing accuracy.
