DETAILED DESCRIPTION

[0030] The following will disclose multiple embodiments of the utility model with diagrams. For the purpose of clear description, many physical details will be described together in the following description. However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0031] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0032] like Figures 1 to 5 As shown, when a traditional damper is used, the anti-seismic measures set inside it are generally single damping measures. After long-term use, the single anti-seismic measure is prone to reduced effectiveness, and the effect of the single measure is not easy to guarantee when used in high-intensity scenarios. Based on this, it needs to be improved.

[0033] The present application provides a stable and high fatigue type viscous damper, wherein the viscous damper 4 is installed between two embedded parts 3, and the two ends of the viscous damper 4 are respectively connected to the two embedded parts 3; the two embedded parts 3 are respectively arranged on two opposite cantilever walls 2, and a preset distance is maintained between the two cantilever walls 2, and the two cantilever walls 2 are arranged in a fixed frame 1.

[0034] Specifically, the viscous damper 4 includes a movable end 41 and a fixed end 44, the movable end 41 and the fixed end 44 are respectively adapted to the embedded part 3, a shell 43 is arranged between the movable end 41 and the fixed end 44, an inner cavity 49 is arranged inside the shell 43, and an accommodating cavity is opened inside the inner side of one end of the inner side of the inner cavity 49 close to the fixed end 44, and an elastic member 47 is installed at the accommodating cavity;

[0035] A piston rod 42 is provided at one end of the movable end 41, and one end of the piston rod 42 extends to the inner side of the inner cavity 49. A push rod 48 is provided at the middle of the inner cavity 49 of the piston rod 42, and one or more buffer cylinders 45 are symmetrically provided with the push rod 48. A telescopic member 46 is provided on the inner side of the buffer cylinder 45, and the distal end of the telescopic member 46 is provided on the outer side of the accommodating cavity.

[0036] When the building structure is subjected to an earthquake or other vibration, the movable end 41 and the fixed end 44 of the viscous damper 4 will move relative to each other; at this time, the piston rod 42 of the movable end 41 moves inside the inner cavity 49, the push rod 48 is pushed outward through the buffer cylinder 45, and the telescopic member 46 will expand or contract. In this process, the elastic member 47 provides elastic support in the inner cavity 49. When the push rod 48 is pushed forward, part of the energy is converted into compression energy and stored in the elastic member 47. When the vibration is reduced or stopped, the relative movement between the movable end 41 and the fixed end 44 will cause the push rod 48 and the telescopic member 46 to retract, releasing the previously stored energy. At the same time, the viscous effect also comes into play, so that the vibration amplitude of the structure is controlled and slowed down.

[0037] Through the structural design of the frame 1 and the cantilever wall 2 and the setting of the embedded parts 3, the installation stability of the viscous damper 4 is enhanced, and it can better withstand external vibrations; the internal structural design of the viscous damper 4 takes fatigue issues into consideration, and through the design of the elastic member 47 and the push rod 48, energy storage and release are achieved, thereby improving the fatigue durability of the viscous damper 4;

[0038] The combined design of the piston rod 42, the push rod 48 and the telescopic member 46 can enhance the viscous effect of the viscous damper 4, making the viscous damper 4 more effective in controlling structural vibration; the optimization of the overall design and the internal structure enables the viscous damper 4 to function better in earthquakes or other vibration environments, thereby improving the seismic resistance of the building structure.

[0039] See also Figure 5 and Figure 6 The inner side of the inner cavity 49 is filled with a medium, a fixing plate 412 is provided in the middle of the inner cavity 49 , and the middle of one side of the fixing plate 412 is adapted to one end of the push rod 48 .

[0040] An extrusion plate 410 is disposed in the middle of the other side of the fixing plate 412 . The middle of the extrusion plate 410 is concave at a preset angle for contacting with the medium to improve the damping effect.

[0041] A magnetic plate adapted to the extrusion plate 410 is disposed on the inner side of the elastic member 47 to increase the damping of the extrusion plate 410 .

[0042] The inner side of the inner cavity 49 is filled with a medium, which may be a liquid, a gas or other substances that can provide a damping effect. The selection of the filling medium needs to take into account its damping performance and stability.

[0043] When the building structure vibrates, the medium in the inner cavity 49 is acted upon by an external force, and the medium exerts pressure on the fixing plate 412 and the extrusion plate 410. The movement of the push rod 48 and the piston rod 42 causes the extrusion plate 410 to contact the medium and produce a damping effect. At the same time, the presence of the elastic member 47 can provide additional support and damping, thereby increasing the stability and durability of the viscous damper 4.

[0044] By optimizing the filling medium, the design of the extrusion plate 410 and the elastic member 47, the damping effect of the viscous damper 4 is enhanced, which can more effectively reduce the vibration amplitude of the structure. The design of the fixed plate 412 and the extrusion plate 410 can improve the stability of the viscous damper 4, making it more reliable in a vibration environment. The introduction of the magnetic plate increases the damping effect of the extrusion plate 410, further optimizing the performance of the viscous damper 4, so that it can perform well under different vibration conditions.

[0045] like Figures 5 to 9 The fixing plate 412 is located on the outer side of the extrusion plate 410 and is symmetrically provided with two penetration holes 415 , and the penetration holes 415 are adapted to the telescopic member 46 .

[0046] At least two grooves are formed in an annular array on the outer side of the fixing plate 412 . A clamping frame 414 is disposed in the groove. A ball bearing 413 is disposed inside the clamping frame 414 .

[0047] A sliding groove 411 is provided on the inner side of the inner cavity 49 at the ball 413 of the fixing plate 412 , and the sliding groove 411 is adapted to fit the ball 413 .

[0048] The fixing plate 412 is located outside the extrusion plate 410 and is symmetrically provided with two through holes 415 , which are adapted to the telescopic member 46 so that the fixing plate 412 and the telescopic member 46 can be well connected, thereby ensuring the structural stability and movement accuracy of the viscous damper 4 .

[0049] The outer side of the fixing plate 412 is provided with at least two grooves in a circular array, each groove is provided with a card frame 414, and the inner side of the card frame 414 is provided with a ball 413 to provide additional support and positioning between the fixing plate 412 and the inner cavity 49, thereby enhancing the structural stability and durability of the viscous damper 4.

[0050] A slide groove 411 is provided on the inner side of the inner cavity 49 at the ball 413 of the fixed plate 412 . The slide groove 411 is adapted to the ball 413 . The slide groove 411 enables the ball 413 to slide freely in the inner cavity 49 , thereby reducing movement resistance and improving movement efficiency of the viscous damper 4 .

[0051] When the building structure is subjected to vibration, the relative movement between the fixed plate 412 and the extrusion plate 410 will cause the telescopic member 46 to expand and contract, thereby producing a damping effect. At the same time, the through hole 415 of the fixed plate 412 is tightly connected with the telescopic member 46, ensuring the stability and reliability of the telescopic member 46. The grooves and the card frame 414 of the annular array provide additional support and positioning, making the viscous damper 4 more stable and reliable in a vibration environment. The adaptation of the slide groove 411 and the ball 413 reduces the friction between the internal components and improves the movement efficiency and durability of the viscous damper 4.

[0052] The adaptation of the through hole 415 and the telescopic member 46, the design of the annular array of grooves and the card frame 414 enhance the connection stability between the internal components of the viscous damper 4, and ensure the reliability of the viscous damper 4 in a vibration environment.

[0053] The design of the slide groove 411 and the ball 413 reduces the friction between the internal components, improves the movement efficiency of the viscous damper 4, and reduces energy loss.

[0054] The annular array of grooves and the card frame 414 provide additional positioning support, making the position of the internal components of the viscous damper 4 more stable, thereby enhancing the durability and fatigue resistance of the viscous damper 4.

[0055] It should be noted that the telescopic member 46 plays a key role in the movement of the viscous damper 4. In some embodiments, the telescopic member 46 may be in the following specific forms:

[0056] Spring expansion parts: Springs are one of the most common types of expansion parts. They can adjust the stiffness and damping effect of the damper according to the degree of compression and release. Spring expansion parts can be made of steel or alloy materials, have high elastic modulus and durability, and are suitable for most damper application scenarios.

[0057] Hydraulic telescopic parts: Hydraulic telescopic parts use the compression and release of liquid in a closed container to achieve a damping effect. The advantage of hydraulic telescopic parts is that they can provide a relatively smooth damping force, which is suitable for occasions that require fine adjustment. Common hydraulic telescopic parts include hydraulic cylinders, hydraulic valves, etc.

[0058] Pneumatic expansion joints: Pneumatic expansion joints use the compression and release of gas in a container to achieve a damping effect. It is usually lighter than hydraulic expansion joints and is suitable for occasions with high weight requirements. Common types of pneumatic expansion joints include pneumatic cylinders, pneumatic springs, etc.

[0059] Rubber expansion joints: Rubber expansion joints use the elastic deformation of rubber materials to absorb and release energy to achieve damping effect. It has good wear resistance and corrosion resistance and is suitable for damper design in some special environments.

[0060] It is understandable that the above are only some specific examples of the telescopic member 46, which does not mean that only the above components or structures can be used. Other components or structures with telescopic functions can also be used; the above specific examples cannot be used as a limitation on the protection scope of the present utility model.

[0061] The type of filling medium mainly depends on the specific design requirements and application scenarios of the damper. Common filling media include:

[0062] Liquid filling medium: Liquid filling medium can be water, oil or liquid polymer, etc. They have good fluidity and compressibility and can provide a relatively stable damping effect.

[0063] Gas filling medium: The gas filling medium can be air or other gases. They have low density and compressibility, can provide lightweight damping effect, and are suitable for some occasions with high weight requirements.

[0064] Solid filling medium: Solid filling medium can be foam plastic, rubber and other materials. They have high stability and durability, can provide lasting damping effect, and are suitable for some long-term use occasions.

[0065] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
