This rigid design makes installation and disassembly complex, especially in situations with limited space or complex pipeline layouts. Furthermore, rigid pipe clamps cannot effectively absorb vibrations, which may cause noise in the hydraulic system connected to the pipeline, affecting the system's stability and service life.

[0031] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0032] like Figure 1-Figure 5 As shown, the flexible clamping assembly of this embodiment of the invention includes a sleeve 1 and a plurality of clamping members 2.

[0033] The sleeve 1 is used to fit onto the pipe 100. Multiple clamping members 2 are arranged at intervals along the circumference of the sleeve 1. In the direction from the clamping member 2 to the sleeve 1, the clamping member 2 includes a fixed base 21, a flexible part 22 and a clamping part 23 connected in sequence. The clamping part 23 is located on the side of the clamping member 2 adjacent to the sleeve 1. The multiple clamping parts 23 define a clamping area. The sleeve 1 is placed in the clamping area, and the outer peripheral wall of the sleeve 1 abuts against the clamping part 23. The flexible part 22 includes a first segment 221, a second segment 222 and a third segment 223 connected in sequence in the direction from the clamping member 2 to the sleeve 1. The first segment 221 is flexible in a first direction, the second segment 222 is flexible in a second direction, and the third segment 223 is flexible in a third direction. The first direction, the second direction and the third direction are orthogonal to each other.

[0034] Specifically, such as Figures 1-3As shown, the sleeve 1 is fixedly fitted onto the pipe 100 to protect and secure the pipe 100. Multiple clamping elements 2 are arranged around the sleeve so that the pipe 100 can pass through the middle of the assembly formed by the multiple clamping elements 2, thereby firmly fixing the pipe 100 within the clamping area. This not only maintains the stability of the pipe 100 but also makes the stress distribution around the pipe 100 more uniform.

[0035] like Figures 1-3 As shown, the clamping member 2 comprises three parts: a fixed base 21, a flexible part 22, and a clamping part 23. The flexible part 22 connects the fixed base 21 and the clamping part 23, and can provide slight displacement or adjustment for the clamping part 23 as a whole. The first segment 221, the second segment 222, and the third segment 223 are arranged between the fixed base 21 and the clamping part 23, allowing the clamping part 23 to deflect to a certain extent in the first, second, and third directions, respectively, thereby ensuring the flexibility of the pipeline 100. The first clamping part 23 and the second clamping part 23 can be connected by screws or bolts, that is, the pipeline 100 can be placed in the gap between the first clamping part 23 and the second clamping part 23, and the pipeline 100 can be fixed on the clamping part 23 by the connection of screws or bolts.

[0036] It should be noted that, as Figures 1-3 As shown, the first direction, the second direction, and the third direction are the X-axis direction, the Y-axis direction, and the Z-axis direction, respectively. Therefore, the length direction, thickness direction, and height direction of the clamping member 2 are parallel to the Y-axis direction, the X-axis direction, and the Z-axis direction, respectively.

[0037] Optionally, the arrangement order of the first segment 221, the second segment 222, and the third segment 223 can be determined according to the usage environment or installation position of the clamping device. That is, along the extension direction of the Z-axis, the first segment 221, the second segment 222, and the third segment 223 can be connected sequentially, or the first segment 221, the third segment 223, and the second segment 222 can be connected sequentially; or the second segment 222, the first segment 221, and the third segment 223 can be connected sequentially; or the second segment 222, the third segment 223, and the first segment 221 can be connected sequentially; or the third segment 223, the second segment 222, and the first segment 221 can be connected sequentially; or the third segment 223, the first segment 221, and the second segment 222 can be connected sequentially. In addition, the fixed base 21, the first segment 221, the second segment 222, the third segment 223, and the clamping part 23 can be connected by threaded connection, plug-in connection, or snap-fit ​​connection to facilitate the assembly and disassembly of each component.

[0038] In other words, the flexible clamping component 22 of this embodiment can absorb vibration along multiple bending directions, reducing noise and impact caused by vibration, thereby improving the stability and service life of the system connected to the pipeline 100. Furthermore, by utilizing the bendability of the clamping member 2, installation and disassembly can be completed without damaging the pipeline 100, especially in environments with confined spaces or complex pipe layouts.

[0039] In some embodiments, the sleeve 1 is rotatable about the center of the sleeve 1 relative to the clamping portion 23. It is understood that, as Figures 1-3 As shown, the sleeve 1 and the clamping part 23 are connected by a ball joint, that is, the outer peripheral wall of the sleeve 1 is spherical, and the clamping part 23 is provided with an arc-shaped groove on the side adjacent to the sleeve 1. The arc-shaped grooves on multiple clamping parts 23 form a spherical groove that matches the outer peripheral wall of the sleeve 1, so that the sleeve 1 can fit in the spherical groove.

[0040] Preferably, the sleeve 1 is provided with barriers 11 at both ends. The barriers 11 and the sleeve 1 can be detachably connected by screws, plugs, or snaps to facilitate installation and disassembly. In addition, the radial dimension of the barrier 11 is larger than the port dimension of the arc-shaped groove adjacent to the barrier end, so as to further improve the stability of the sleeve 1 in restricting the pipeline 100.

[0041] In some embodiments, the thickness of the first segment 221 is less than the thickness of the fixed base 21 in the thickness direction of the clamping member 2. It is understood that, as Figures 1-3 As shown, the thickness of the first segment 221 is less than the thickness of the fixed base 21, which enables the clamping member 2 to bend relative to the fixed base 21 after being subjected to a force in the X-axis, thereby realizing the bending function of the clamping assembly in the X-axis.

[0042] Preferably, there are multiple first segments 221, and the multiple first segments 221 are arranged at intervals along the thickness direction of the clamping member 2. For example... Figures 1-3 As shown, multiple first segments 221 are arranged sequentially and at intervals along the X-axis to ensure the overall strength of the clamping member 2.

[0043] Optionally, such as Figures 1-3 As shown, there are two first segments 221. The two first segments 221 are placed on both sides of the clamping member 2 with the plane parallel to the Y and Z axes as the plane of symmetry. This ensures the flatness between the clamping member 2 and the first segment 221 and avoids the first segment 221 from protruding too much and making it unusable in narrow spaces.

[0044] In some embodiments, the length of the second segment 222 is less than the length of the fixed base 21 in the longitudinal direction of the clamping member 2. It is understood that, as Figures 1-3As shown, the length of the second segment 222 is less than the length of the clamping member 2, which enables the clamping member 2 to bend relative to the clamping member 2 after being subjected to a force along the Y-axis, thereby realizing the bending function of the clamping assembly in the Y-axis.

[0045] Preferably, there are multiple second segments 222, which are arranged at intervals along the length of the clamping member 2. It can be understood that the multiple second segments 222 are arranged sequentially at intervals along the Y-axis to ensure the overall strength of the clamping member 2.

[0046] Optionally, such as Figures 1-3 As shown, there are two second segments 222. The two second segments 222 are placed on both sides of the clamping member 2 with the plane parallel to the X and Z axes as the plane of symmetry. This ensures the flatness between the clamping member 2 and the second segment 222, and avoids the second segment 222 from protruding too much, which would make it unusable in narrow spaces.

[0047] In some embodiments, the third segment 223 includes a first flexible portion 2231, a connecting portion 2232, and a second flexible portion 2233 connected sequentially along the height direction of the clamping member 2. The first flexible portion 2231 is located between the connecting portion 2232 and the second segment 222, and the second flexible portion 2233 is located between the connecting portion 2232 and the clamping portion 23. There are multiple third segments 223, and the multiple third segments 223 are arranged opposite to each other in the length direction of the fixed base.

[0048] Specifically, such as Figures 1-3 As shown, the two ends of the first flexible part 2231 are connected to the connecting part 2232 and the second segment 222, respectively, and the two ends of the second flexible part 2233 are connected to the connecting part 2232 and the clamping part 23, respectively. That is, the first flexible part 2231 and the second flexible part 2233 are arranged on both sides of the connecting part 2232, and a deformable space is formed between the first flexible part 2231 and the second flexible part 2233 so that the third segment 223 can undergo slight displacement and adjustment when subjected to a force along the Z-axis.

[0049] Optionally, such as Figures 1-3 As shown, there can be multiple first flexible portions 2231 and multiple second flexible portions 2233, and multiple first flexible portions 2231 and multiple second flexible portions 2233 are arranged sequentially at intervals along the extension direction of the connecting portion 2232.

[0050] In some embodiments, the connecting portion 2232 is spaced apart from the sidewall of the clamping member 2 in a plane orthogonal to the thickness direction of the fixed base 21. It is understood that, as Figures 1-3As shown, the first flexible part 2231, the connecting part 2232, and the second flexible part 2233 are connected in sequence to form a "ji" - shaped structure, so that after the third segment 223 is subjected to a force in the Z - axis direction, it bends relative to the fixed base 21, thereby realizing the adjustment of the clamping device in the Z - axis direction.

[0051] In the plane where the Y - axis and the Z - axis are located, the first flexible part 2231, the connecting part 2232, and the second flexible part 2233 form a "ji" - shaped structure. Of course, in the plane where the X - axis and the Z - axis are located, the first flexible part 2231, the connecting part 2232, and the second flexible part 2233 can also be configured to form a "ji" - shaped structure. That is to say, with the center line of the clamping device as the axis, the "ji" - shaped structure formed by the first flexible part 2231, the connecting part 2232, and the second flexible part 2233 can be arranged in any direction, so as to be applicable to different scenarios.

[0052] Preferably, the fixed base 21, the first segment 221, the second segment 222, the third segment 223, and the clamping part 23 are integrally formed. It can be understood that, as Figures 1-3 shown, in the Z - axis direction, the fixed base 21, the first segment 221, the second segment 222, the third segment 223, and the clamping part 23 are arranged in sequence, and according to different use environments, materials with certain elasticity, flexibility, and strength can be used, such as: stainless steel, aluminum alloy, copper alloy, silica gel, rubber, polyurethane, polyethylene, polypropylene, nylon, and carbon fiber composite materials, etc.

[0053] It should be noted that, as Figures 1-3 shown, if a part of the clamping member 2 is integrally formed, a through - hole penetrating the clamping member 2 is opened along the Y - axis direction on the side of the clamping member 2 adjacent to the fixed base 21, and the side wall of the through - hole forms the clamping part 23; similarly, a through - hole penetrating the clamping member 2 is opened along the X - axis direction, and the side wall of the through - hole forms the second segment 222; the third segment 223 of the clamping member 2 between the clamping part 23 and the second segment 222 can be cut and formed by using a cutting device.

[0054] Preferably, multiple clamping members 2 are integrally formed. It can be understood that, as Figure 4 shown, using the integral - forming method not only makes the connection between multiple clamping members 2 more firm, the overall structure more stable, not easy to loosen or fall off, but also reduces the number of parts that need to be separately processed and assembled, simplifying the structural design.

[0055] In some other embodiments, the clamping member 2 further includes a first limiting protrusion 24 and a second limiting protrusion 25. The first limiting protrusion 24 is connected to the fixed base 21, and there is a gap between the side wall of the first limiting protrusion 24 and the first segment 221 and the second segment 222.

[0056] Specifically, as Figure 5 As shown, the first limiting protrusion 24 is placed in the space enclosed by the fixed base 21, the first segment 221 and the second segment 222, and one end of the first limiting protrusion 24 is connected to the fixed base 21. There is a certain gap between the side wall of the first limiting protrusion 24 adjacent to the first segment 221 and the first segment 221, and there is a certain gap between the side wall of the first limiting protrusion 24 adjacent to the second segment 222 and the second segment 222.

[0057] Understandably, during the bending process of the first segment 221, due to the presence of the first limiting protrusion 24, the first segment 221 will abut against the first limiting protrusion 24 after bending to a certain extent. Thus, the first limiting protrusion 24 can be used to support the first segment 221, preventing the displacement of the first segment 221 from being too large, thereby ensuring the support strength and overall stability of the clamping member 2.

[0058] like Figure 5 As shown, the second limiting protrusion 25 is placed within the space enclosed by the first segment 221, the second segment 222 and the third segment 223, and one end of the second limiting protrusion 25 is connected to the first segment 221. There is a certain gap between the side wall of the second limiting protrusion 25 adjacent to the second segment 222 and the second segment 222, and there is a certain gap between the side wall of the second limiting protrusion 25 adjacent to the third segment 223 and the third segment 223.

[0059] Understandably, during the bending process of the second segment 222, due to the presence of the second limiting protrusion 25, the second segment 222 will abut against the second limiting protrusion 25 after bending to a certain extent. Thus, the second limiting protrusion 25 can be used to support the second segment 222, preventing the displacement of the second segment 222 from being too large, thereby ensuring the support strength and overall stability of the clamping member 2.

[0060] like Figure 2 and Figure 6 As shown, the distance between the first flexible part 2231 and the second segment 222 is a1, the distance between the second flexible part 2232 and the clamping part 23 is a2, and the distance between the first flexible part 2231 and the second flexible part 2232 is b. Then a1+a2≥b.

[0061] It is understandable that, as shown in the figure, when the third segment 223 is subjected to compressive force, the ends of the first flexible part 2231 and the second flexible part 2232 away from the connecting part 2233 abut against each other, and the clamping part 23 moves toward the second segment 222, so that the gap between the clamping part 23 and the second segment 222 is compressed. Since a1+a2≥b, interference between the connecting part 2233 and the clamping part 23 and the second segment 222 can be avoided.

[0062] Optionally, In other words, a1 = a2, which ensures that the bending effect of the first flexible part 2231 and the second flexible part 2232 is consistent when they bend, resulting in more coordinated bending movements. Preferably,

[0063] Optionally, such as Figure 7 As shown, there are two clamping members 2, which are symmetrically arranged on both sides of the pipeline 100 along the extension direction orthogonal to the pipeline 100.

[0064] In some embodiments, the flexible clamping assembly of the present invention further includes a fixing member 3, the plurality of clamping members 2 are divided into a plurality of clamping groups, a clamping group includes a plurality of clamping members 2, the clamping group is detachably connected to the fixing member 3, and the plurality of clamping groups are arranged at intervals along the extension direction of the fixing member 3.

[0065] It is understandable that, such as Figure 7 As shown, taking two clamping members 2 as an example, the fixing member 3 and the fixing base 21 can be detachably connected by bolts or the like. The multiple clamping groups of fixing members 3 are arranged at intervals in their extending directions so that multiple clamping groups can fix multiple pipes 100, thereby improving the application flexibility of the flexible clamping assembly of this embodiment of the invention.
