[0027] The following is in conjunction with the appendix Figures 1-3 The present invention will be described in further detail below.

[0028] Please refer to the attached diagram in the instruction manual. Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a combined GIS shell structure, comprising a first shell 1 and a second shell 2, wherein flanges are provided at the ends of both the first shell 1 and the second shell 2, and flanges are provided at the ends of the pipes on both the first shell 1 and the second shell 2.

[0029] Two first fixing plates 3 are symmetrically arranged on the outer walls at both ends of the first housing 1, and two second fixing plates 4 are symmetrically arranged on the outer walls at both ends of the second housing 2. The first fixing plates 3 and the second fixing plates 4 are fitted together. Several bolts 5 are movably inserted into the first fixing plates 3. The lower ends of the bolts 5 pass through the first fixing plates 3 and the second fixing plates 4 and are threaded with nut sleeves 6. First, the first housing 1 and the second housing 2 are spliced ​​together, and the first fixing plates 3 and the second fixing plates 4 are brought into contact. Then, the bolts 5 are inserted into the first fixing plates 3 and the second fixing plates 4. Then, the nut sleeves 6 are threaded onto the lower ends of the bolts 5, so that the first fixing plates 3 and the second fixing plates 4 are fixed together by the cooperation of the nut sleeves 6 and the bolts 5.

[0030] The second fixing plate 4 has a circular groove 41 on its side wall. An anti-loosening component 42 is movably disposed in the circular groove 41. The lower end of the anti-loosening component 42 abuts against the outer wall of the nut sleeve 6. The circular groove 41 facilitates the assembly of the anti-loosening component 42. When the anti-loosening component 42 abuts against the nut sleeve 6, the possibility of the nut sleeve 6 loosening is reduced.

[0031] The anti-loosening component 42 is U-shaped and is connected to the side wall of the second fixing plate 4 via a tension spring 43. One end of the anti-loosening component 42 is movably inserted into the inner wall of the circular groove 41, and the other end of the anti-loosening component 42 is fixedly provided with a rubber plate 44. The rubber plate 44 abuts against the outer wall of the nut sleeve 6. The tension spring 43 facilitates the movement of the anti-loosening component 42, thereby causing the anti-loosening component 42 to pull the rubber plate 44 to move and abut against the nut sleeve 6, thus reducing the possibility of the nut sleeve 6 automatically rotating and falling off.

[0032] The inner wall of the nut sleeve 6 is fixedly provided with an abutment rod 7, the lower end of the bolt 5 is provided with a movable groove 8, the inner wall of the movable groove 8 is provided with several positioning parts 9, the inner wall of the movable groove 8 is provided with an assembly groove 81, the positioning parts 9 are movably disposed in the assembly groove 81, and the positioning parts 9 are easily assembled through the assembly groove 81.

[0033] The upper end of the abutment rod 7 is inserted into the movable groove 8 and abuts against one end of the positioning member 9. The inner wall of the nut sleeve 6 is provided with an internal thread groove 61 that matches the external thread on the bolt 5. The abutment rod 7 is fixedly installed in the internal thread groove 61. A semi-circular block 71 is fixedly installed at the upper end of the abutment rod 7. When the nut sleeve 6 is installed on the bolt 5, the abutment rod 7 is inserted into the movable groove 8 and abuts against the positioning member 9. Thus, the abutment rod 7 pushes the positioning member 9 to move and causes the positioning member 9 to extend out of the bolt 5 and insert into the positioning groove, thereby fixing the bolt 5 in the second fixing plate 4.

[0034] The other end of the positioning member 9 is movably inserted into the inner wall of the second fixing plate 4. The first fixing plate 3 and the second fixing plate 4 are provided with through holes 10 for the bolt 5 to pass through. The bolt 5 is movably inserted into the through holes 10. The inner wall of the through holes 10 in the second fixing plate 4 is provided with positioning grooves corresponding to the positioning member 9. The bolt 5 can pass through the first fixing plate 3 and the second fixing plate 4 through the through holes 10. The bolt 5 and the nut sleeve 6 are used to fix the first fixing plate 3 and the second fixing plate 4 together. When the positioning member 9 extends out of the bolt 5, it is inserted into the positioning groove, thereby fixing the bolt 5 in the second fixing plate 4 and reducing the possibility of the bolt 5 loosening.

[0035] The positioning component 9 includes a positioning plate 91. A semi-cylinder 92 is fixedly mounted on one end of the positioning plate 91 facing the abutment rod 7. The other end of the positioning plate 91 passes through the assembly groove 81 and is inserted into the positioning groove. The semi-cylinder 92 is connected to the inner wall of the assembly groove 81 by a spring 93. When the abutment rod 7 is inserted into the movable groove 8, it abuts against the semi-cylinder 92, thereby causing the semi-cylinder 92 to move the positioning plate 91. This causes the positioning plate 91 to extend out and the bolt 5 to be inserted into the positioning groove. As the semi-cylinder 92 moves, the spring 93 is compressed and deformed. When the nut sleeve 6 is removed, the abutment rod 7 separates from the semi-cylinder 92. At this time, the spring 93 pushes the semi-cylinder 92 and the positioning plate 91 to move, thereby causing the positioning plate 91 to be retracted into the assembly groove 81 and separated from the positioning groove, thus facilitating the operator to remove the bolt 5.

[0036] Working principle: When using this combined GIS shell structure, firstly, the first shell 1 and the second shell 2 are spliced ​​together, and the first fixing plate 3 and the second fixing plate 4 are brought into contact. Then, the bolt 5 is inserted into the first fixing plate 3 and the second fixing plate 4, and then the nut sleeve 6 is threaded onto the lower end of the bolt 5. Thus, the first fixing plate 3 and the second fixing plate 4 are fixed together by the cooperation of the nut sleeve 6 and the bolt 5.

[0037] As the nut sleeve 6 is connected to the bolt 5, the abutment rod 7 is inserted into the movable groove 8. At this time, the abutment rod 7 abuts against the positioning member 9 and pushes the positioning member 9 to move, thereby causing the positioning member 9 to extend out of the bolt 5 and insert into the second fixing plate 4, thus fixing the bolt 5 in the second fixing plate 4 and reducing the possibility of the bolt 5 loosening. Therefore, the connection between the first housing 1 and the second housing 2 is more secure.

[0038] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
