[0034] See also Figure 1 - Figure 6 A multi-channel shock absorber includes a shock absorber body 1 with a multi-channel structure 101 and a piston assembly 102. One end of the shock absorber body 1 is provided with a first connecting member 2 connected through a connecting end member 4, and the other end is provided with a second connecting member 3 connected through an assembly base 301. An inner sleeve 401 is provided in the connecting end member 4, and the first connecting member 2 is provided with a connecting tube 202 matching the inner sleeve 401.

[0035] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6The multi-channel shock absorber of the present application is mainly composed of a shock absorber body 1, a multi-channel structure 101 and a piston assembly 102. A first connecting member 2 and a second connecting member 3 are respectively provided at both ends of the shock absorber body 1, and a connecting end member 4 and an assembly base plate 301 are fixedly installed at both ends of the shock absorber body 1. The connecting end member 4 cooperates with the first connecting member 2 for installation in a planar position, and the assembly base plate 301 cooperates with the second connecting member 3 for installation in a non-planar position. While the above is suitable for installation requirements in different positions, the detachable design of the first connecting member 2 and the second connecting member 3 is also convenient for direct replacement when the installation position is different, so as to improve applicability and be more convenient in operation.

[0036] It should also be noted that the second connecting member 3 and the assembly base plate 301 are fastened by bolts, and the bolt structure arranged around it can pass through the second connecting member 3 to connect it to the position of the corresponding plane. At the same time, a notch is provided between the second connecting member 3 and the assembly base plate 301, and the position of the second connecting member 3 on the assembly base plate 301 can be changed by cooperating with bolts and nuts, thereby improving applicability.

[0037] In the present application, a connecting tube 202 and a stabilizing protrusion 402 are also provided, wherein the connecting tube 202 is provided on the first connecting member 2, and the thread provided on the outside thereof matches the internal thread of the stabilizing protrusion 402, and the stabilizing protrusion 402 is fixedly installed on the inner wall of the connecting end member 4. By rotating the connecting tube 202 to be threadedly connected to the inside of the stabilizing protrusion 402, the first connecting member 2 can be installed as a whole.

[0038] In the present application, a securing plate 201 is also provided, which is fixedly installed between the first connecting member 2 and the connecting tube 202. When the connecting tube 202 is rotated and connected to the inside of the stabilizing protrusion 402, the securing plate 201 is driven to be squeezed on the surface of the connecting end member 4, thereby performing a limiting operation on the first connecting member 2 being installed.

[0039] A sealing ring 5 is also provided in the present application. Since oil will flow in the multi-channel structure 101 inside the upper part of the shock absorber body 1, through the design of the sealing ring 5, when the securing plate 201 is squeezed against the surface of the connecting end piece 4 and contacts it, the sealing effect of the connection between the two can be improved by providing the sealing ring 5 between the two.

[0040] In the present application, a first positioning groove 6 and a second positioning groove 601 are also provided. The first positioning groove 6 is opened inside the securing plate 201, and the second positioning groove 601 is opened inside the connecting end piece 4, so that one end of the sealing ring 5 can be clamped into the second positioning groove 601, and the other end drives the other end of the sealing ring 5 to be clamped into the first positioning groove 6 when the securing plate 201 is squeezed to the surface of the connecting end piece 4, thereby improving the stability of the sealing ring 5 during application and facilitating replacement operation after long-term use.

[0041] In the present application, an installation plug 501 is also provided, and the installation plug 501 is glued to the two ends of the bottom of the sealing ring 5. When the installation plug 501 is driven to be clamped into the second positioning groove 601, the installation plug 501 is correspondingly inserted into the groove provided inside the connecting end piece 4. The insertion end of the installation plug 501 is larger and elastic, so that the stability of the connection can be further improved when the sealing ring 5 is installed.

[0042] The present application also provides a guide opening 403, which is fixedly installed at the opening of the connecting end piece 4. When the securing plate 201 is squeezed onto the connecting end piece 4, the securing plate 201 can be located inside the guide opening 403, thereby further limiting the peripheral portion of the securing plate 201. At the same time, the guide opening 403 has a curved design, which makes it convenient for the first connecting piece 2 to drive the securing plate 201 to rotate into it, thereby bringing convenience to operation.

[0043] In the present application, a preset hole 7 and a fastening bolt 701 are also provided. The preset hole 7 is opened on both sides of the guide opening 403, and its inner end can pass through the securing plate 201. When the securing plate 201 is squeezed on the opening surface of the connecting end piece 4, the fastening bolt 701 is threadedly connected to the inside of the preset hole 7, and the first connecting piece 2 being installed can be further locked to ensure stability during installation.

[0044] The present application also provides a protective sleeve 8 and a support structure 801, wherein the protective sleeve 8 and the support structure 801 are designed as an integrated structure, and the support structure 801 is installed at the upper and lower ends of the protective sleeve 8.
