Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-5 , an embodiment provided by the utility model:

[0023] A heat insulation board for a fuel evaporation closed chamber includes a heat insulation board body 1, a metal shell 2 is provided on the surface of the heat insulation board body 1, a mounting groove 3 is provided on the surface of the metal shell 2, a first connecting plate 4 and a second connecting plate 5 are fixedly connected to the surface of the mounting groove 3, an insertion groove 6 is provided inside the first connecting plate 4, a storage groove 7 is provided inside the second connecting plate 5, a plug-in rod 8 and a support spring 10 are installed on the surface of the storage groove 7, a connection groove 9 is provided on the surface of the plug-in rod 8, a moving groove 11 and a card groove 12 are provided on the surface of the second connecting plate 5, a push block 13 is fixedly connected to the side of the plug-in rod 8, a fixed plate 14 is fixedly connected to the surface of the push block 13, a mounting plate 15 and a side plate 16 are provided inside the heat insulation board body 1, the metal shell 2 is completely wrapped and covered on the outer surface of the heat insulation board body 1, and then the splicing effect of multiple groups of heat insulation board bodies 1 can be achieved by splicing the metal shell 2.

[0024] Furthermore, the size of the metal shell 2 is larger than the size of the insulation board body 1, and four groups of mounting grooves 3 are provided. The four groups of mounting grooves 3 are arranged on both sides of the metal shell 2, and the number of each group of mounting grooves 3 is two. Two groups of mounting grooves 3 are installed on the surface of the first connecting plate 4, and the other two groups of mounting grooves 3 are installed on the surface of the second connecting plate 5. The four groups of mounting grooves 3 are distributed on both sides with one of the diagonals of the insulation board body 1 as the boundary, and the first connecting plate 4 or the second connecting plate 5 on each group of mounting grooves 3 are placed opposite to each other. By arranging mounting grooves 3 on all four sides of the metal shell 2, the metal shell 2 can achieve horizontal and vertical splicing effects to meet the different size requirements of the fuel evaporation closed chamber.

[0025] Furthermore, the size of the first connecting plate 4 is smaller than that of the second connecting plate 5, and two groups of insertion grooves 6 and storage grooves 7 are provided. The two groups of insertion grooves 6 are opened on both sides of the first connecting plate 4, and the two groups of storage grooves 7 are opened on both sides of the second connecting plate 5. The diameter of the insertion groove 6 is the same as the diameter of the storage groove 7, the spacing between the two groups of insertion grooves 6 is the same as the spacing between the two groups of storage grooves 7, the length of the storage groove 7 is greater than the length of the insertion groove 6, and when the first connecting plate 4 and the second connecting plate 5 are connected, both are plugged into each other's mounting groove 3.

[0026] Furthermore, one side of the plug-in rod 8 is movably connected to the surface of the storage groove 7, and the other side of the plug-in rod 8 is plugged into the surface of the plug-in groove 6. The diameter of the connecting groove 9 is larger than the outer diameter of the support spring 10. The plug-in rod 8 can limit the connection between the first connecting plate 4 and the second connecting plate 5 on the installation groove 3, thereby achieving the splicing effect of adjacent insulation boards, and the installation of the support spring 10 can be achieved through the connecting groove 9.

[0027] Furthermore, one end of the support spring 10 is connected to the surface of the storage slot 7, and the other end of the support spring 10 is connected to the surface of the connecting slot 9. The length of the movable slot 11 is smaller than the length of the storage slot 7. There are two groups of card slots 12. Under the action of the support spring 10, a supporting force can be applied to the plug-in rod 8, so that the plug-in rod 8 is inserted away from one end of the support spring 10 and abuts against the surface of the plug-in slot 6, thereby making the connection between the first connecting plate 4 and the second connecting plate 5 on the mounting slot 3 more secure.

[0028] Furthermore, two groups of slots 12 are arranged on both sides of the movable slot 11, and the size of the slot 12 is larger than the size of the pushing block 13. The pushing block 13 is slidably connected to the surface of the movable slot 11, and the pushing block 13 is engaged and connected to the surface of the slot 12. The fixed plate 14 is movably connected to the surface of the slot 12. Under the action of the movable slot 11 and the slot 12, the pushing block 13 can be moved on its surface. Under the connection between the pushing block 13 and the slot 12, the limiting effect of the plug-in rod 8 can be achieved, and when the pushing block 13 is engaged in the slot 12, the fixed plate 14 can be placed on the surface of the slot 12. At the same time, the pushing block 13 can be moved out of the slot 12 more conveniently through the fixed plate 14, and the plug-in rod 8 can be driven to move by moving the pushing block 13, thereby realizing the telescopic transformation of the support spring 10.

[0029] Furthermore, the cross-section of the side panels 16 is "L"-shaped, and two groups of side panels 16 are provided. The two groups of side panels 16 are fixedly connected to both sides of the mounting plate 15. The connection between the side panels 16 and the mounting plate 15 can form a triangular structure with strong stability. The side panels 16 are distributed in a linear array on the mounting plate 15. At the same time, the mounting plate 15 and the side panels 16 on both sides form an assembly arranged in the insulation board body 1.

[0030] Working principle: When splicing the insulation panels, first align the side of the second connecting plate 5 installed on one set of metal shells 2 with the side of the first connecting plate 4 installed on the other set of metal shells 2, and align the length and width of the two sets of spliced ​​insulation panels. Then, the first connecting plate 4 and the second connecting plate 5 can be inserted into the installation groove 3 on the opposite side. At the same time, the fixing plate 14 is pulled out from the card slot 12 on the side away from the insertion groove 6 to drive the push block 13 and the plug rod 8 to rotate, and the push block 13 is canceled from the plug-in state of the card slot 12 of the group. At this time, under the action of the supporting force exerted by the support spring 10 on the plug-in rod 8 through the connecting groove 9, the plug-in rod 8 can slide in the storage groove 7 and insert the end away from the support spring 10 into and engage with the plug-in groove 6, while the pushing block 13 slides along the surface of the movable groove 11. Finally, the pushing block 13 is rotated again to engage with the slot 12 close to the side of the plug-in groove 6, so as to drive the plug-in rod 8 to rotate on the surface of the storage groove 7, and the fixing plate 14 moves to the slot 12 on this side, thereby completing the splicing effect of adjacent insulation boards.

[0031] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
