[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 , Figure 2 , Figure 4The utility model provides an embodiment: a long-life gapless viscous damper, including a damper body 1. The damper body 1 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The damper body 1 has a buffering effect. A damping rod 2 is arranged on the left surface of the damper body 1. The damping rod 2 is connected to the damper body 1. A connecting rod 3 is fixedly connected to the left surface of the damping rod 2. A ball head 4 is fixedly connected to the left surface of the connecting rod 3. The ball head 4 is set to a spherical shape and can rotate in any direction. A lubrication component is arranged on the left surface of the ball head 4. The lubrication component can apply lubricating liquid to the surface of the ball head 4 to ensure its lubrication during rotation, reduce the wear of the ball head 4 during rotation, and extend the device. The service life of the lubrication assembly includes a connecting seat 51, a concave flange 52 is fixedly connected to the right surface of the connecting seat 51, and a round tube 53 is penetrated and fixedly connected to the upper surface of the concave flange 52. Lubricating oil can be added from the round tube 53, and a one-way valve 54 is arranged in the middle section of the round tube 53. The one-way valve 54 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The one-way valve 54 can enable one-way flow of the fluid. Lubricating oil can only be added to the concave flange 52 from the round tube 53, and the lubricating oil inside the concave flange 52 cannot flow out. A quick-release assembly is arranged on the right surface of the concave flange 52. The lubrication assembly, the quick-release assembly, the damping rod 2, the connecting rod 3 and the ball head 4 are arranged in two groups, which are symmetrically arranged with the center of the damper body 1.

[0032] Reference Figure 1 , Figure 2 , Figure 4 The lubrication assembly also includes a convex flange 55, which is fitted with the concave flange 52. A sealing gasket 56 is fixedly connected to the right surface of the convex flange 55. The sealing gasket 56 can prevent the lubricating oil from leaking out of the convex flange 55. The inner wall of the concave flange 52 is provided with multiple groups of oil storage holes 501, and the inner wall of the concave flange 52 is provided with a connecting channel 502. The lubricating oil added to the concave flange 52 will stay in the oil storage hole 501 and the connecting channel 502, so as to lubricate the ball head 4.

[0033] Reference Figure 1 , Figure 3 The quick-release assembly includes a card block 62, and a rubber ring 63 is fixedly connected to the outer wall of the middle section of the card block 62. The rubber ring 63 is soft and will deform when squeezed. A card groove 601 is provided on the right surface of the concave flange 52, and the card groove 601 fits with the card block 62. The card groove 601 is slightly larger than the card block 62. An arc groove 602 is provided on the inner wall of the concave flange 52. A bolt 61 penetrates and is threadedly connected to the right surface of the convex flange 55. The bolt 61 can fix the concave flange 52 and the convex flange 55 together.

[0034] Reference Figure 1 , Figure 2 , Figure 4 The ball head 4 slides on the inner wall of the concave flange 52, and the outer wall of the ball head 4 fits with the inner wall of the concave flange 52, which can avoid the rapid leakage of lubricating oil, avoid the waste of lubricating oil, and greatly reduce the connection gap, thereby preventing the problem of large connection gap affecting the buffering effect, thereby ensuring the buffering effect of the device.

[0035] Reference Figure 1 , Figure 2 , Figure 4 The left surface of the convex flange 55 is set to be convex, and the right surface of the concave flange 52 is set to be concave. The convex flange 55 and the concave flange 52 are plugged into each other, and the two can form a seal.

[0036] Reference Figure 1 , Figure 2 , Figure 4 The sealing gasket 56 is made of rubber material. The sealing gasket 56 is in close contact with the outer wall of the ball head 4 to prevent the lubricating oil from leaking out. The oil storage hole 501 is connected to the connecting channel 502. The oil storage hole 501 passes through the upper surface of the concave flange 52 and is connected to the round tube 53. The lubricating oil added from the round tube 53 will penetrate into the oil storage hole 501. There are multiple groups of oil storage holes 501, which are evenly distributed inside the concave flange 52 and connected through the connecting channel 502.

[0037] Reference Figure 1 , Figure 3 The right surface of the clamping block 62 is fixedly connected to the left surface of the convex flange 55, and the clamping groove 601 is connected to the arc groove 602.

[0038] Reference Figure 1 , Figure 3 The block 62 is inserted into the inner wall of the slot 601, and the rubber ring 63 is inserted into the inner wall of the arc slot 602, which can align the concave flange 52 and the convex flange 55 and avoid sliding during installation, reducing the time spent on aligning the bolt 61 and improving the installation efficiency. The bolt 61 passes through and is threadedly connected to the right surface of the concave flange 52.

[0039] Working principle: When the device is used, first align and plug the block 62 and the slot 601. During the plugging, the rubber ring 63 will be squeezed and deformed, and the rubber ring 63 will move along the trajectory of the slot 601. When the block 62 and the slot 601 are plugged in, the rubber ring 63 will be aligned with the arc groove 602, and the rubber ring 63 will be plugged into the arc groove 602 due to its own elastic recovery. At this time, in the absence of external force, the concave flange 52 will not separate from the convex flange 55. At this time, the threaded holes on the concave flange 52 and the convex flange 55 will be aligned, and then the bolt 61 will be installed. After installation, the convex flange 55 and the concave flange 52 will be tightly attached, and the sealing gasket 56 will also be tightly attached to the surface of the ball head 4. In this way, the concave flange 52 and the convex flange 55 on both sides can be quickly installed together, reducing the time spent on installation work and improving installation efficiency.

[0040] Then add the lubricating oil from the circular tube 53. The lubricating oil will flow downward along the trajectory of the circular tube 53, pass through the one-way valve 54 and flow into the oil storage hole 501 and the connecting channel 502. The lubricating oil in the oil storage hole 501 will contact the ball head 4, so that the surface of the ball head 4 is coated with the lubricating oil, reducing the wear between the ball head 4 and the concave flange 52 when it rotates, which can extend the service life of the device. The lubricating oil will produce a small amount of loss during use. If it needs to be added, the lubricating oil can be directly added from the circular tube 53.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
