[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0027] like Figure 1-6 As shown, an expandable turbocharger diffuser plate comprises a diffuser plate 1, a sealing groove 2 is provided on the side of the diffuser plate 1, an integrally formed positioning block 3 is provided inside the sealing groove 2, a first expansion plate 4 and a second expansion plate 5 are provided on the outer side of the diffuser plate 1, a sealing convex ring 6 is provided on the inner side surface of the first expansion plate 4 and the second expansion plate 5, a positioning groove 7 is provided on the sealing convex ring 6, a docking groove 8 is provided at one end of the first expansion plate 4, a docking plate 9 is provided at one end of the second expansion plate 5, a screw hole 10 is penetrated between the docking groove 8 and the top of the first expansion plate 4, a screw hole 10 is also penetrated between the top surface of the docking plate 9 and the ground, and the screw holes 10 of the docking groove 8 and the docking plate 9 are screwed and fixed by countersunk screws 11.

[0028] The pressure diffuser plate 1 of the device can be quickly expanded by assembling with the first expansion plate 4 and the second expansion plate 5 , and has good sealing and stability, effectively meeting the expansion requirements of the pressure diffuser plate 1 .

[0029] The positions of the positioning groove 7 and the positioning block 3 form an angle of ninety degrees with the connection between the first expansion board 4 and the second expansion board 5 .

[0030] The positions of the positioning grooves 7 and the positioning blocks 3 form a ninety-degree angle with the connection between the first expansion board 4 and the second expansion board 5, so that when the positioning grooves 7 and the positioning blocks 3 are inserted into each other, the docking grooves 8 and the docking board 9 can also be inserted synchronously, and the situation where the docking grooves 8 and the docking boards 9 cannot be inserted into each other is avoided.

[0031] The screw hole 10 between the docking groove 8 and the first expansion plate 4 is a countersunk screw hole.

[0032] The screw hole 10 between the docking groove 8 and the first expansion plate 4 is a countersunk screw hole for matching with a countersunk screw 11 .

[0033] Reinforcing ribs 12 are provided on the inner sides of the first expansion plate 4 and the second expansion plate 5 .

[0034] The reinforcing ribs 12 are used to improve the structural strength of the first expansion plate 4 and the second expansion plate 5 .

[0036] The size of the docking groove 8 is the same as that of the docking plate 9, so that the two can be firmly inserted and connected.

[0037] Working principle and use process of the utility model: When the device is used, when the area of ​​the pressure diffuser 1 needs to be expanded, the positioning grooves 7 on the first expansion plate 4 and the second expansion plate 5 are aligned with the positioning block 3 on the pressure diffuser 1, and the sealing convex ring 6 is inserted and connected with the sealing groove 2. In this process, the docking groove 8 on the first expansion plate 4 and the docking plate 9 of the second expansion plate 5 are also inserted and connected. Then, the countersunk screws 11 are used to connect the docking grooves 8 and the screw holes 10 on the docking plates 9 to complete the assembly of the device. Through the cooperation of the sealing convex ring 6 and the sealing groove 2, the first expansion plate 4 and the second expansion plate 5 are connected. The expansion panel 5 and the pressure diffuser plate 1 can maintain sealing to avoid air leakage, and the setting of the positioning block 3 and the positioning groove 7 not only facilitates the rapid positioning and assembly between the pressure diffuser plate 1 and the first expansion panel 4 and the second expansion panel 5, but also during use, the mutual limitation of the positioning block 3 and the positioning groove 7 also avoids the rotation of the first expansion panel 4 and the second expansion panel 5, thereby improving stability. In summary, the pressure diffuser plate 1 of the present device can be quickly expanded by assembly with the first expansion panel 4 and the second expansion panel 5, and at the same time has good sealing and stability, effectively meeting the expansion needs of the pressure diffuser plate 1.
