DETAILED DESCRIPTION

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0020] For example, see Figure 2 Combined with Figure 3 , Figure 2 A three-dimensional diagram of a preferred embodiment of a connecting tube of the present invention; Figure 3 For the present invention Figure 2 The enlarged structural diagram at A in the figure. Figures 2 to 3 As shown, at least one embodiment provides a connecting cylinder, including: a cylinder body 101 and a plurality of connecting parts 102, the cylinder body 101 is used to load the center hole position of the cam 200, and the connecting part 102 is used to connect the connecting cylinder 100 with the cam 200. It should be further explained that the connecting part 102 is a long strip or a long wave shape, which not only plays a connecting effect, but also can strengthen the rib effect. Specifically, the connecting cylinder 100 has an external leakage surface 103 and an internal surface 104 corresponding to the external leakage surface 103. The connecting part 102 is arranged on the side wall of the cylinder body 101, and one side of the connecting part 102 can be flush with the external leakage surface 103. In order to relatively fix the connecting cylinder 100 and the cam 200, it is necessary to connect them by bolts. Specifically, a plurality of assembly holes 105 are arranged on the connecting part 102. The assembly hole 105 is provided with a settling groove 106 in the direction toward the external leakage surface 103 . The bolt is inserted into the assembly hole 105 from the direction toward the external leakage surface 103 , and the nut is positioned at the position of the settling groove 106 .

[0021] Embodiment 2, at least one embodiment provides a connecting cylinder, comprising: a cylinder body 101 and a plurality of connecting parts 102, the connecting cylinder 100 having an external leakage surface 103 and an internal surface 104 corresponding to the external leakage surface 103, the connecting part 102 is arranged on the side wall of the cylinder body 101, and one side of the connecting part 102 can be flush with the external leakage surface 103. The connecting part 102 is provided with a plurality of assembly holes 105. The assembly hole 105 is provided with a settling groove 106 in the direction toward the external leakage surface 103, and the settling groove 106 is used to accommodate a nut.

[0022] Please continue reading Figure 2 Combined with Figure 3 to Figure 4 , Figure 4 FIG. 1 is a schematic diagram of the structure of the optimal embodiment of the bottom pressure ring of the present invention. Figures 2 to 4As shown, a rotation-blocking member is provided in the sedimentation tank 106. The rotation-blocking member includes an outer pressure ring 107 and a bottom pressure ring 108. The outer pressure ring 107 and the bottom pressure ring 108 are both elastic capsules. The wall thickness of the capsule of the outer pressure ring 107 is smaller than that of the capsule of the bottom pressure ring 108. In a natural state, the outer pressure ring 107 bulges. After it is squeezed, the internal gas rushes to the bottom pressure ring 108 to make it bulge slightly upward. The outer pressure ring 107 is arranged on the side of the sedimentation tank 106, and the bottom pressure ring 108 is arranged on the bottom surface of the sedimentation tank 106. The outer pressure ring 107 and the bottom pressure ring 108 are connected to each other. The bottom pressure ring 108 includes a plurality of first sections 109, and two adjacent first sections 109 are connected by a second section 1010. The thickness of the second section 1010 is greater than that of the first section 109. When the internal gas rushes toward the bottom pressure ring 108, the bulge of the first section 109 is greater than that of the second section 1010, forming a high and low staggered annular surface. Therefore, when the nut is pressed against and squeezed against it, it has the effect of preventing rotation. In this way, the purpose of enhancing the sealing effect while preventing the nut from rotating and preventing the connection from loosening can be achieved.

[0023] On the other hand, see Figure 5 Combined with Figure 6 , Figure 5 A three-dimensional diagram of a preferred embodiment of a cam of the present invention; Figure 6 1 is a stereogram of the best embodiment of a connecting cylinder and a cam assembly of the present invention. Figure 5 to Figure 6 The present invention further provides a cam assembly, comprising: a cam 200 and the above-mentioned connecting tube 100. The cam 200 comprises a wheel disc 201 and a thickened edge 202, wherein the thickened edge 202 is centrally arranged on the side wall of the wheel disc 201, and the thickness of the thickened edge 202 is three times the thickness of the wheel disc 201. A group of reinforcing ribs 203 are arranged on the wheel disc 201, and each two reinforcing ribs 203 form a group. A calibration groove 204 is formed on the wheel disc 201 between a group of reinforcing ribs 203, and the connecting portion 102 is suitable for being embedded in the calibration groove 204. The cam is arranged in a structural form with different thicknesses, which can reduce the overall weight of the cam assembly while enhancing the stability of power transmission.

[0024] In summary, by providing the connecting portion 102 and the reinforcing ribs 203, the load-bearing strength of the cam assembly during operation is enhanced, and deformation during operation is effectively avoided; by providing the outer pressure ring 107 and the bottom pressure ring 108, the sealing strength of the installation gap position is enhanced while the loosening of the locking member during rotation is avoided, thereby ensuring the stability of the cam assembly operation; by providing the thickened edge 202, the overall weight of the cam assembly is reduced while the stability of power transmission is enhanced.
