DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

[0023] Please refer to Figures 1-4 In the present application, a high-viscosity silicone oil damper comprises a sealed housing 1, a piston column 2, a moving piston block 3, a fixed piston block 4 and a connecting piece 5. The right end of the piston column 2 penetrates and is sealed to slide into the inside of the sealed housing 1. The moving piston block 3 is integrally formed with the piston column 2. The outside of the moving piston block 3 is slidably connected to the inside of the sealed housing 1. The fixed piston block 4 is fixedly installed to the inside of the sealed housing 1. High-viscosity silicone oil is injected into the cavity between the left side of the fixed piston block 4 and the sealed housing 1. The right end of the piston column 2 penetrates and is sealed to slide to the right side of the fixed piston block 4. The connecting piece 5 is fixedly connected with the left end of the piston column 2 through bolts.

[0024] The inside of the moving piston block 3 is provided with through holes 31 distributed in a ring shape for silicone oil flow. The inside of the moving piston block 3 is provided with an inner ring groove 6. The inner ring groove 6 is in communication with half of the through holes 31. The inside of the inner ring groove 6 is installed with an adjusting piece 7. The adjusting piece 7 is used to adjust the passing sectional area of the through holes 31.

[0025] The adjusting piece 7 comprises an adjusting column 71, a rotating block 72, a rotating disc 73 and a plurality of half-moon teeth 74. The right end of the adjusting column 71 penetrates and is resistively rotated to the inside of the piston column 2 and is fixedly connected with the rotating block 72. The outside of the rotating block 72 is rotatably connected to the inside of the adjusting column 71. The other side of the rotating block 72 is fixedly connected with the rotating disc 73. The rotating disc 73 is rotatably connected to the inside of the inner ring groove 6. The plurality of half-moon teeth 74 are fixedly connected to the outside of the rotating disc 73 at equal distances. The half-moon teeth 74 are correspondingly matched with the through holes 31.

[0026] In this invention, the right end of the sealing housing 1 is mounted on the support end, and the piston rod 2 is connected to the equipment end via the connector 5. When the piston rod 2 is subjected to force, the piston rod 2 causes the moving piston block 3 to slide along the inside of the sealing housing 1, squeezing the silicone oil on one side and causing it to flow to the other side through the through hole 31. The high viscosity of the silicone oil generates flow resistance, providing damping and realizing the function of a damper. When it is necessary to adjust the damping force, firstly, the adjusting column 71 is rotated to drive the rotating block 72 and the rotating disk 73 to rotate. The rotating disk 73 drives the crescent tooth 74 to rotate inside the inner ring groove 6. 74 As it rotates, the through hole 31 is gradually blocked, changing its cross-sectional area, thereby adjusting the flow rate of the silicone oil. This allows the device to flexibly adjust the damping value of the silicone oil damper, making it more adaptable to different usage needs and more convenient and flexible to use. It solves the problem that in the prior art, the damping effect is generally achieved by opening through holes in the internal piston and using different hole diameters to generate different flow resistances. However, the resistance value of a single silicone oil damper is fixed and difficult to adjust, and different models are required for different usage scenarios.

[0027] Please see Figure 1 The connecting component 5 includes a first connecting ring 51, a T-shaped rod 52 and two pads 53. The right side of the first connecting ring 51 is fixedly connected to the T-shaped rod 52, and the other end of the T-shaped rod 52 is fixedly connected to the two pads 53. The T-shaped rod 52 and the pads 53 are fixedly connected to the piston column 2 by bolts.

[0028] In this utility model, the first connecting ring 51 serves as the connection to the equipment end. The T-shaped rod 52, together with the pad block 53, is connected to the piston column 2 with bolts, while creating a gap between the T-shaped rod 52 and the piston column 2. This gap allows the tool to be inserted to drive the adjusting column 71 to adjust the damping, making operation convenient.

[0029] Please see Figure 1 Among them, a dustproof elastic sleeve 8 is fitted between the left end of the sealed housing 1 and the T-shaped rod 52.

[0030] In this utility model, the dustproof elastic sleeve 8 is used to protect the outer side of the connecting piece 5 and the piston column 2 from dust. Taking advantage of the stretchable nature of the dustproof elastic sleeve 8, when adjustment is needed, the dustproof elastic sleeve 8 can be compressed to expose the adjustment gap for operation.

[0031] Please see Figure 1 The sealing housing 1 is a metal shell, and an aluminum heat sink 9 is fixedly connected to the outside of the sealing housing 1.

[0032] In this invention, the heat dissipation efficiency of the entire damper is enhanced by the aluminum heat dissipation sleeve 9 on the outside of the sealed housing 1, thereby improving its service life and stability.

[0033] Please see Figure 1 The left end of the adjusting column 71 extends into the gap between the T-shaped rod 52 and the piston column 2, and the left end of the adjusting column 71 is fixedly connected to the drive head 711 of the wrench tool.

[0034] In this invention, the gap between the T-shaped rod 52 and the piston rod 2 is used to insert a tool to adjust the drive head 711, thereby achieving flexible adjustment.

[0035] Please see Figure 1 The right end of the sealed housing 1 is fixedly connected to a second connecting ring 10.

[0036] In this invention, the second connecting ring 10 facilitates the connection between the sealing housing 1 and the supporting end.

[0037] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
