Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0026] See also Figures 1 to 3 The present invention provides a technical solution: an adjustable modular self-locking vibration dual-control support, comprising an upper rotating connector 1, a lower fixed connector base 2 and a locking adjustment mechanism 8, an upper fixed collar 5 is placed on the outer side of the upper rotating connector 1, and the upper end surface of the lower fixed connector base 2 is fixed with a lower fixed connector upper extension tube 3 and a lower fixed collar 4, the lower fixed collar 4 is fixed to the inner wall of the lower fixed connector upper extension tube 3, the bottom of the upper rotating connector 1 is threadedly connected with an upper damper mechanism 6, the upper damper mechanism 6 rests on the bottom of the upper fixed collar 5, and the bottom of the upper damper mechanism 6 is connected to the lower damper mechanism 7 through a spring 10, the types of spring 10 include but are not limited to disc springs, wave springs, steel coil springs and rubber blocks, and the lower damper mechanism 7 is placed on the top of the lower fixed collar 4.

[0027] In this embodiment, Figure 2 and Figure 3 As shown, the upper damper mechanism 6 includes an upper damper outer cylinder 601, and the upper damper outer cylinder 601 is filled with damping fluid, an upper damper damping plate 602 is slidably connected to the upper damper outer cylinder 601, and an upper damper guide rod 603 is fixed on the upper damper damping plate 602. When the support is in a tension state, the upper rotating connection 1 drives the lower damper mechanism 7 and the upper damper guide rod 603 to move upward together, and the upper damper damping plate 602 and the upper damper outer cylinder 601 undergo relative displacement, and the shearing and extrusion effects of the damping fluid are consumed during the movement.

[0028] In this embodiment, Figure 2 and Figure 3 As shown in the drawings, the upper damper guide rod 603 penetrates the upper damper outer cylinder 601, and the top of the upper damper guide rod 603 is threadedly connected to the bottom of the upper rotary connecting piece 1. When the static displacement of the support changes due to the change of the load on the upper part of the support, and the overall height of the support needs to be adjusted, the upper rotary connecting piece 1 can be rotated, and the relative rotation between the upper rotary connecting piece 1 and the upper damper guide rod 603 can realize the adjustment of the overall height of the support.

[0029] In this embodiment, as shown in Figure 2 and Figure 3 , the lower damper mechanism 7 includes a lower damper outer cylinder 701, and the lower damper outer cylinder 701 is filled with damping liquid. A lower damper damping plate 702 is slidably connected in the lower damper outer cylinder 701, and a lower damper guide rod 703 is fixed to the lower damper damping plate 702. When the support is in a compression state, the upper rotary connecting piece 1 drives the upper damper mechanism 6 and the lower damper guide rod 703 to move downward together, and the lower damper damping plate 702 and the lower damper outer cylinder 701 are relatively displaced, and the shear and extrusion of the damping liquid during the movement can dissipate energy.

[0030] In this embodiment, as shown in Figure 2 and Figure 3 , the lower damper guide rod 703 penetrates the lower damper outer cylinder 701, and the top of the lower damper guide rod 703 is connected to the upper damper guide rod 603 through a guide rod fixing cylinder 11. The guide rod fixing cylinder 11 serves to connect the upper damper guide rod 603 and the lower damper guide rod 703.

[0031] In this embodiment, as shown in Figure 2 and Figure 3 , the bottom of the lower damper guide rod 703 is fixed with a fixed plate 9, and a through hole is formed in the fixed plate 9. The bottom of the lower damper outer cylinder 701 is fixed with a lower damper limiting protruding rod 704, and the lower damper limiting protruding rod 704 penetrates the through hole. The upper damper guide rod 603, the guide rod fixing cylinder 11, the lower damper guide rod 703 and the fixed plate 9 are fixedly connected to form an integral whole, and the fixed plate 9 is rotationally locked by the lower damper limiting protruding rod 704.

[0032] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3 , vertical slots are symmetrically formed on both sides of the lower fixed connecting piece upper extension cylinder 3, which provide a certain space for the upward and downward movement of the locking upper sliding plate 801.

[0033] In this embodiment, as shown in Figure 1 , Figure 2 and Figure 3As shown, the locking adjustment mechanism 8 includes a locking upper slide 801, and the locking upper slide 801 passes through the vertical slot and is connected to the upper fixed ring 5. A locking upper screw 802 is fixed to the bottom of the locking upper slide 801. The locking upper slide 801, the locking upper screw 802 and the upper fixed ring 5 can move up and down as a whole.

[0034] In this embodiment, Figure 1 、 Figure 2 and Figure 3 As shown, a locking lower screw 804 is fixed on the base 2 of the lower fixed connector, and the top of the locking lower screw 804 is connected to the bottom of the locking upper screw 802 through a locking threaded outer cylinder 803. The locking threaded outer cylinder 803 is threadedly connected to the outside of the locking upper screw 802 and the locking lower screw 804. The overall length of the locking adjustment mechanism 8 is adjusted by rotating the locking threaded outer cylinder 803, thereby realizing convenient adjustment of the support preload or the compression change caused by the change of the load on the upper part of the support.

[0035] The use method and advantages of the present invention: The adjustable modular self-locking vibration dual-control support has the following working process:

[0036] like Figures 1 to 3 As shown: the overall length of the locking adjustment mechanism 8 is adjusted by rotating the locking threaded outer cylinder 803, so as to realize convenient adjustment of the support preload or the compression caused by the change of the load on the upper part of the support. When the support is in a compressed state, the upper rotating connector 1 drives the upper damper mechanism 6 as a whole and the lower damper guide rod 703 to move downward together, and the lower damper damping plate 702 is fixedly connected to the lower damper guide rod 703 and is relatively displaced with the lower damper outer cylinder 701. During the movement, the shearing and squeezing effects on the damping fluid are exerted. The upper damper mechanism 6 and the lower damper mechanism 7 consume energy. During the compression process, the relative distance between the upper damper mechanism 6 and the lower damper mechanism 7 becomes smaller, which produces a squeezing effect on the spring 10, providing the support with bearing capacity and vibration isolation / vibration capacity. When the support is compressed and deformed beyond a preset value, the lower end surface of the guide rod fixing cylinder 11 abuts against the upper end surface of the lower damper outer cylinder 701, so that the support as a whole cannot continue to deform, and is in a locked state to protect the spring 10 from excessive compression and damage. When the support is compressed and then changes to a tensile state, the spring 10 can push the lower damper outer cylinder 701 to reset.

[0037] When the support is in a tension state, the upper rotating connector 1 drives the lower damper mechanism 7 as a whole and the upper damper guide rod 603 to move upward together. The upper damper damping plate 602 is fixedly connected to the upper damper guide rod 603 and is relatively displaced with the upper damper outer tube 601. During the movement, the shearing and squeezing effects of the damping fluid are consumed. During the tension process, the relative distance between the upper damper mechanism 6 and the lower damper mechanism 7 becomes smaller, which produces a squeezing effect on the spring 10, providing the support with bearing capacity, vibration isolation / vibration capacity and tensile and anti-lifting capacity. When the tensile deformation of the support exceeds the preset value, the upper end surface of the guide rod fixing tube 11 abuts against the lower end surface of the upper damper outer tube 601, so that the support as a whole cannot continue to deform and is in a locked state to protect the spring 10 from excessive compression and damage, and at the same time prevent lift-off from overturning the upper structure. When the support is pulled and then changes to a compressed state, the spring 10 can push the upper damper outer tube 601 to reset;

[0038] The upper damper guide rod 603, the guide rod fixing tube 11, the lower damper guide rod 703 and the fixing plate 9 are fixedly connected to form a whole. The fixing plate 9 is rotationally locked by the lower damper limiting protrusion 704. When the load on the upper part of the support changes, resulting in a change in the static displacement of the support, and the overall height of the support needs to be adjusted, the upper rotating connector 1 can be rotated, and the upper rotating connector 1 and the upper damper guide rod 603 rotate relative to each other to achieve the adjustment of the overall height of the support.
