[0008] Further, the inner side angle of the first positioning hole is in the form of a rounded structure to reduce stress concentration.

[0009] Further, the outer side opening of the first positioning hole is in the form of an outward guiding structure inclined to both sides to improve the assembly performance.

[0010] Further, the second positioning hole is formed by transition connection of an oblong hole A and an oblong hole B together, the width of the oblong hole A is greater than that of the oblong hole B, and the length of the oblong hole B is greater than that of the oblong hole A, so that the size and performance of the ring are not affected by the segmented design.

[0011] The utility model discloses the beneficial effect that:

[0012] The utility model discloses two positioning holes are added on the ring main part, make when the ring is assembled to the rubber pipe, assemble to the corresponding boss position department of rubber pipe, make the position of the ring shell and the direction of fixed bolt fixed, thereby increase the consistency of ring assembly position, also realize the consistency of fixed bolt and the tightening tool when the ring is tightened, thereby improve the assembly efficiency, and the position of ring main body is positioned when being tightened equivalent to rubber pipe, avoid the problem that the ring will produce left and right deflection when being tightened, and need not manual adjustment ring direction, greatly improve assembly efficiency and quality.

[0013] The utility model discloses the first positioning hole is set to the structure of the notch, like this more benefit fast ring is assembled to the corresponding position of rubber pipe, improve assembly efficiency. DRAWINGS

[0021] Embodiment 1

[0022] As shown in the figure, one end of the hoop body 1 is fixedly provided with a fixed plate 2, one side of the fixed plate 2 is provided with a hoop shell 3, a fixed bolt 4 is installed in the hoop shell 3, a plurality of locking grooves 11 are arranged on the hoop body 1 away from the connecting fixed plate, the end of the hoop body 1 provided with the locking groove 11 passes through the hoop shell 3 and the locking groove 11 on the hoop body 1 is connected with the fixed bolt 4,

[0023] As Figure 1 , a first positioning hole 12 and a second positioning hole 13 are arranged in sequence on the hoop body 1 at the position beside the connecting fixed plate 2.

[0024] As Figure 2 , the first positioning hole 12 is provided in a notch structure, and the inner side angle of the first positioning hole 12 is provided in a rounded structure, so that the contact position is more smooth, thereby reducing stress concentration. And the outer side opening of the first positioning hole 12 is provided as an outer guide structure inclined to both sides, so that the outer shell opening end is larger than the inner side of the hole, which is more conducive to quickly assembling the hoop to the corresponding position of the rubber pipe, improving the assembly efficiency.

[0025] As Figure 3The second positioning hole 13 is formed by a long hole A (131) and a long hole B (132) being connected together, wherein the long hole A (131) has a larger width than the long hole B (132), and the long hole B (132) has a larger length than the long hole A (131). The long hole A (131) with a larger width is used to be quickly assembled to the boss of the rubber tube, and then the long hole B (132) is used for fine adjustment. The segmented design improves the assembly rate and provides a larger adjustment range in a limited space without affecting the size and performance of the hoop.

[0026] The two positioning holes added on the hoop body 1 can be obtained by stamping. Through the two positioning holes, the hoop is assembled to the corresponding boss position on the rubber tube. After assembly, the position of the hoop shell 3 and the direction of the fixing bolt 4 are fixed, so that the hoop is prevented from being left and right inclined when the tool is tightened. The direction of the fixing bolt 4 is fixed, which improves the consistency with the tool, thereby improving the assembly efficiency.
