[0026] The present invention will be further described below with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it. However, the embodiments are not intended to limit the present invention.

[0027] Reference Figures 1-6 As shown, a clamp for a supercharger volute of the utility model includes a clamp shell 1, and arc-shaped movable grooves 5 are provided on both sides of the clamp shell 1. Two connecting screws 17 are slidably connected in the arc-shaped movable grooves 5, and one end of the connecting screw 17 is fixedly connected to an adjusting block 15, and an arc-shaped sliding rod 14 is slidably connected between the adjacent sides of the connecting screw 17 close to the adjusting block 15, and both ends of the arc-shaped sliding rod 14 are fixedly connected to end limit blocks 13, and an arc-shaped limit plate 2 is provided on the side of the adjusting block 15 away from the connecting screw 17, and the arc-shaped limit plate 2 is slidably connected to the clamp shell 1.

[0028] During operation, first open the clamp by using a tool, then pry open the clamp shell 1 to both sides, and buckle the clamp on the connection between the supercharger volute and the connecting pipe of the vehicle, and then tighten and close the clamp with a tool, so that the clamp, supercharger volute and connecting pipe are precisely combined, wherein the arc-shaped limit plates 2 on both sides contact and squeeze the connection between the supercharger volute and the connecting pipe of the vehicle, and the inner side of the arc-shaped limit plate 2 is set to a slope shape, which can increase the pressure on the supercharger volute and the connecting pipe when the clamp is closed.

[0029] Further, such as Figure 2 As shown, a support block 12 is provided on the side of the adjustment block 15 away from the connecting screw 17 , and the support block 12 is fixedly connected to the clamp housing 1 .

[0030] During operation, in the initial state, the arc-shaped limiting plate 2 is supported by the support blocks 12 at both ends.

[0031] Further, such as Figure 2 As shown, the clamp housing 1 is provided with equally spaced positioning grooves 10 on both sides close to the arc-shaped movable groove 5 .

[0032] During operation, the moving position of the connecting screw 17 is determined by the positioning grooves 10. The two positioning grooves 10 in the middle are the initial positions of the connecting screw 17, and the positioning grooves 10 at both ends are the positions of the connecting screw 17 after adjustment.

[0033] Further, such as Figure 5 As shown, the other end of the connecting screw 17 is threadedly connected to the knob 11 , and the end of the knob 11 close to the adjustment block 15 is rotatably connected to the positioning block 19 , and the positioning block 19 corresponds to the positioning slot 10 .

[0034] During operation, the positioning block 19 is driven to move forward and backward by turning the knob 11 in conjunction with the threaded portion of the connecting screw 17 , and the positioning block 19 is further rotationally connected to the knob 11 , so the rotation of the connecting screw 17 does not affect the angle of the positioning block 19 .

[0035] Further, such as Figure 3 As shown, an arc-shaped sliding groove 16 is provided on one side of the arc-shaped limiting plate 2 close to the adjustment block 15 , and two arc-shaped sliders 18 are slidably connected to the inner side of the arc-shaped sliding groove 16 , and the two arc-shaped sliders 18 are fixedly connected to the two adjustment blocks 15 respectively.

[0036] During operation, the arc-shaped limiting plate 2 and the adjusting block 15 are connected via the arc-shaped sliding block 18 , and further via the arc-shaped sliding groove 16 , the adjusting block 15 and the arc-shaped sliding block 18 can slide relative to the arc-shaped limiting plate 2 .

[0037] Further, such as Figure 1 As shown, one end of the upper clamp shell 1 is fixedly connected to a first fixing plate 7, and one end of the lower clamp shell 1 is fixedly connected to a second fixing plate 8. A fixing bolt 6 is provided between the inner sides of the first fixing plate 7 and the second fixing plate 8.

[0038] During operation, one side of the clamp is fixed and disassembled by the second fixing plate 8 and the first fixing plate 7 in cooperation with the fixing bolts 6 .

[0039] Further, such as Figure 6 As shown, a nut limiting groove 20 is provided at the bottom of the second fixing plate 8 , and a fixing nut 9 is threadedly connected to the lower end of the fixing bolt 6 , and the fixing nut 9 cooperates with the nut limiting groove 20 .

[0040] During operation, a blocking block is provided on the upper side of the fixing nut 9, corresponding to the nut limiting groove 20 at the bottom of the second fixing plate 8. When installing the fixing bolt 6 and the fixing nut 9, the upper end of the fixing nut 9 is aligned with the nut limiting groove 20 to prevent the fixing nut 9 from shaking during installation.

[0041] Further, such as Figure 1 As shown, the other ends of the two clamp shells 1 are fixedly connected to hook-shaped connecting blocks 3, and an annular lock buckle 4 is sleeved between the outer circles of the two hook-shaped connecting blocks 3.

[0042] During operation, the hook-shaped connecting blocks 3 on the two clamp shells 1 cooperate with the annular lock buckle 4 to limit the other side of the clamp, so that it has a certain range of motion and is not easy to separate the two parts of the clamp.

[0043] Working principle: When using the clamp for the supercharger volute, first use a tool to unscrew the fixing bolt 6 to disengage the fixing nut 9 and contact the position limit of the first fixing plate 7 and the second fixing plate 8, then pry the clamp housing 1 apart to both sides and buckle the clamp on the connection between the supercharger volute and the connecting pipe of the vehicle, then align the upper part of the fixing nut 9 with the nut limiting groove 20 on the second fixing plate 8 and insert it, and screw on the fixing bolt 6 again with the tool, and the threaded connection between the fixing bolt 6 and the fixing nut 9 cooperates with each other to make the clamp, the supercharger volute and the connecting pipe precisely combined. When the interval between the arc-shaped limiting plates 2 in the default state is too large to meet the installation requirements, first unscrew the knob 11, and use the knob 11 to drive the positioning block 19 away from the clamp housing 1 The adjusting block 15 is moved to the opposite side until the positioning block 19 is disengaged from the positioning groove 10 and the restriction on the connecting screw 17 is released. Then, the connecting screw 17 is pushed forward by the knob 11, so that the adjusting block 15 moves inward and is not in the same longitudinal plane as the support block 12. The knob 11 is further turned to both sides, driving the connecting screw 17 and the adjusting block 15 to move to both sides until the positioning block 19 moves to the position of the positioning groove 10 at the far end. By tightening the knob 11, the positioning block 19 is driven to fit into the positioning groove 10 to limit the relative movement of the adjusting block 15. At this time, the adjusting block 15 moves to coincide with the support block 12. The same operation is performed on one side or both sides to reduce the gap between the two arc-shaped limit plates 2 on the same clamp housing 1, and then the above-mentioned clamp installation steps are repeated to install the clamp to the appropriate position.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
