DETAILED DESCRIPTION

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0032] Reference Figure 1-4, is the first embodiment of the present invention, which provides an assembled skeleton structure of a superconducting magnet, which includes a plurality of basic units 1, specifically:

[0033] A plurality of said basic units 1 are sequentially combined side by side to form a complete skeleton;

[0034] Any two adjacent basic units 1 are detachably connected via a connecting portion;

[0035] A tightening structure is connected between the plurality of basic units 1, and the plurality of basic units 1 are subjected to a squeezing force to be brought closer together due to the action of the tightening structure;

[0036] In the present invention, the tightening structure can be removed. When part of the basic units 1 in the skeleton as a whole need to be removed and replaced, the tightening structure is removed, and the basic units 1 that need to be replaced are separated through the detachable setting, so that the new basic units 1 can be set and incorporated into the original skeleton, and then the tightening structure is installed; compared with the one-piece structure in the prior art, the present invention can ensure local replacement needs through the assembled design between multiple basic units 1. The tightening structure ensures that when the skeleton as a whole encounters low temperature and shrinks, the multiple basic units 1 can still remain as a whole without being loose, thereby ensuring the assembly effect while taking into account the adaptation to the environment during actual use.

[0037] Further, see Figure 1-3 The connecting portion includes an alignment block 2 constructed on the basic unit 1, and also includes a locking block 3. Structurally, when the two basic units 1 are kept in contact with each other, a notch 4 is formed between the two adjacent alignment blocks 2, and the locking block 3 is plugged into the notch 4, so that the separation between the two alignment blocks 2 is limited by the locking block 3 to achieve the connection effect between the two basic units 1. Specifically, the structure of this connecting portion can be set to multiple, and at least three, and the multiple connection units are evenly distributed along the peripheral side of the basic unit 1, so as to maintain the stability of the connection between the two basic units 1.

[0038] Further, see Figure 2 and Figure 3 The slot 4 is also provided with an internal thread, and the locking block 3 is configured with an external thread, which is adapted to the internal thread, thereby increasing the stability of the locking block 3 when inserted in the slot 4, thereby further improving the connection stability between the two basic units 1.

[0039] Further, see Figure 2 and Figure 3The basic unit 1 is also provided with an alignment groove 5, which is used to accommodate the alignment block 2. When two basic units 1 are connected, the alignment block 2 is accommodated in the alignment groove 5 on the other basic unit 1, thereby further increasing the stability effect and the docking accuracy. Before the connection, it can also play the role of alignment between the two basic units 1.

[0040] Further, see Figure 1 and Figure 2 The base unit 1 is provided with a fitting surface 6, and the alignment block 2 is provided with a cover plate 7. When the locking block 3 is assembled in the slot 4, one side of the cover plate 7 contacts the fitting surface 6, so that the edge of the slot 4 can be covered to protect the slot 4. The cover plate 7 can better cooperate with the locking block 3 to apply force when twisting.

[0041] Further, see Figure 1 and Figure 4 The tightening structure includes a first pressing portion 8 and a second pressing portion 9, which are respectively attached to the two basic units 1 at the end of the entire skeleton, and a tightening force is configured between the first pressing portion 8 and the second pressing portion 9 to achieve the effect of gathering multiple basic units 1 together.

[0042] Further, see Figure 4 and Figure 5 Regarding the setting of the tightening force, a connecting rod 10 is also connected to the first pressing portion 8, and the second pressing portion 9 includes a connecting block 901, an expansion block 902 and a force block 903 which are arranged in an overlapping manner. The expansion block 902 is an elastic structure, and the expansion block 902 can be made of rubber. The force block 903 contacts the basic unit 1, and the connecting block 901 is threadedly matched with the connecting rod. When the connecting block 901 and the connecting rod are threadedly connected and tightened, the expansion block 902 is squeezed, and the force block 903 is pressed against the basic unit 1, thereby maintaining the mutual squeezing between the multiple basic units 1. When the whole is cold and shrinks, the squeezing of the expansion block 902 can still maintain the squeezing state of the force block 903 to the basic unit 1, thereby maintaining the tightening effect between the multiple basic units 1.

[0043] Further, see Figure 4 One side of the basic units 1 is provided with a receiving groove 11, which is used to receive the first pressing portion 8. The receiving groove 11 can be used to position the first pressing portion 8 and prevent the first pressing portion 8 from rotating to cooperate with the screwing process between the connecting rod and the connecting block 901.

[0044] Further, see Figure 6The connecting rod is also penetrated with a liquid inlet channel 12 along its length direction, which is used for the passage of refrigerant. Specifically, in actual use, liquid helium can pass through the liquid inlet channel 12 first, so that the connecting rod is cooled and contracted first, thereby increasing the pressure between the connecting units, so that when the multiple basic units 1 are contracted, it is not easy to form a loose effect between each other, thereby further increasing the effect of increasing the stability of the connection.

[0045] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
