Description

Technical Field

[0001] This utility model relates to the field of vibration damping bed technology, and in particular to a sliding force-dissipating vibration damping bed. Background Technology

[0002] In modern high-rise buildings, floors typically collapse entirely or fragment during strong earthquakes. Due to gravitational potential energy, the impact force generated when a floor falls is dozens of times its original weight. Furniture is unlikely to survive intact under such impact, and human survival space is extremely limited, making people vulnerable to injury from beams, columns, floor slabs, and broken bricks, significantly complicating rescue efforts. Existing earthquake-resistant beds with their quadrilateral structures are unstable, and even triangular designs cannot create large survival spaces and are unable to withstand the collapse of stacked floors. Other electrically powered, box-type earthquake-resistant beds are expensive, require ideal conditions to function effectively, and are inconvenient for daily living, hindering widespread adoption. This invention solves the problems of structural stability, insufficient survival space for rescue, and high cost. Moreover, its completely mechanical structure ensures it will not fail and can function normally even without electricity. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a sliding force-dissipating shock-absorbing bed.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0005] This utility model is a sliding shock-absorbing bed, including a shock-absorbing bed top, a shock-absorbing bed column, and a shock-absorbing bed storage chamber. A fixed axis is provided between the shock-absorbing bed top and the shock-absorbing bed column. The shock-absorbing bed storage chamber is fixedly connected to the bottom of the shock-absorbing bed column. A viscous damper is provided at the bottom end of the shock-absorbing bed top and on one side of the shock-absorbing bed column. The shock-absorbing bed top has a barbed anti-detachment buckle. The height of the shock-absorbing bed column is the same as the floor slab.

[0006] As a preferred embodiment of this utility model, the fixed shaft is provided with a fixed shaft bolt inside.

[0007] As a preferred embodiment of this utility model, the side of the top of the shockproof bed is equipped with a barbed anti-detachment buckle.

[0008] As a preferred technical solution of this utility model, the anti-vibration bed column is provided with a column anti-detachment buckle protrusion on one side, which is adapted to the barbed anti-detachment buckle.

[0009] As a preferred technical solution of this utility model, the top of the anti-vibration bed and the anti-vibration bed column form a 90° angle before the anti-vibration bed is started under force, and the top of the anti-vibration bed and the anti-vibration bed column form a 45° angle after the anti-vibration bed is started under force.

[0010] As a preferred embodiment of this utility model, a viscous damper is connected between the top of the anti-vibration bed and the uprights of the anti-vibration bed.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows: By attaching the top to the floor slab, this utility model effectively reduces the distance between the floor slab and the structure, thereby reducing the gravitational potential energy between them. When the floor slab collapses and strikes the structure, the impact force is greatly reduced. Under the action of mechanical fixed-axis friction and viscous damping, when the floor slab collapses, the downward gravity causes the top of the earthquake-resistant bed to compress the viscous damping device while the fixed axis undergoes slow mechanical friction rotation. The top slowly rotates along the fixed axis to form a 45° angle, finally touching the ground to form a stable triangle. This allows the floor slab and building debris to slide down the slope formed by the top, using the slope to dissipate the force of the floor slab impacting the structure. This reduces the impact of the floor slab's gravitational potential energy on the structure, significantly reducing the impact force and improving the structure's survivability. Since the structure's height is the same as the floor level, the resulting triangular space provides a larger survival space, effectively avoiding injury from building debris. It also facilitates self-rescue when the earthquake subsides and provides more operational space for rescue operations. Compared to other roof-mounted earthquake-resistant beds, the improvement lies in raising the structure to the same height as the floor slab. It utilizes viscous dampers and the mechanical friction of fixed-axis rotation to allow the floor slab falling on the structure to slowly press the top of the structure to the ground, forming a stable 45° angle. The top of the structure and the columns are secured by barbs to prevent the structure from opening up, making the structure more stable and stronger, greatly reducing the damage caused by the floor slab falling, and achieving the purpose of stress relief.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0018] In the attached diagram, all identical reference numerals refer to the same components.

[0019] Example 1

[0020] As shown in Figures 1-3, this utility model provides a sliding shock-absorbing bed, including a shock-absorbing bed top 1, a shock-absorbing bed column 6, and a shock-absorbing bed storage chamber 7. The feature is that a fixed shaft 2 is provided between the shock-absorbing bed top 1 and the shock-absorbing bed column 6, the shock-absorbing bed storage chamber 7 is fixedly connected to the bottom of the shock-absorbing bed column 6, and a viscous damper 4 is provided at the bottom end of the shock-absorbing bed top 1 and one side of the shock-absorbing bed column 6.

[0021] Furthermore, the fixed shaft 2 is equipped with a fixed shaft bolt 3 inside. By tightening the fixed shaft bolt 3, the friction between the top 1 of the anti-vibration bed and the fixed shaft 2 is increased.

[0022] The top of the vibration-damping bed 1 is equipped with a top hook anti-detachment buckle 5 on its side. The top hook anti-detachment buckle 5 rotates with the top of the vibration-damping bed 1. When the top hook anti-detachment buckle 5 comes into contact with the upright of the vibration-damping bed 6, it is locked with the anti-detachment buckle protrusion 8 of the upright. The top of the vibration-damping bed 1 and the upright of the vibration-damping bed 6 form a 45° angle.

[0023] Before the vibration isolation bed top 1 and the vibration isolation bed column 6 are put into use, they form a 90° angle. After the vibration isolation bed top 1 and the vibration isolation bed column 6 are put into use, they form a 45° angle. After the 45° angle is formed, the whole body is in a triangular state. Triangles have better stability, thus improving stability.

[0024] The top of the anti-vibration bed 1 and the top column 6 of the anti-vibration bed are locked by the fixed axis bolt 3. The height of the top column 6 of the anti-vibration bed is the same as that of the floor slab. The ratio of the height of the top column 6 of the anti-vibration bed to the length of the top of the anti-vibration bed 1 satisfies the triangle cosine theorem.

[0025] The materials of the anti-vibration bed top 1, fixed axis 2, fixed axis bolt 3, viscous damper 4, top barb anti-detachment buckle 5, anti-vibration bed column 6, and anti-vibration bed column 7 can be made of iron, iron alloy, stainless steel, titanium alloy, or carbon fiber, depending on the actual situation; at the same time, according to... Figure 1 It is known to be rectangular, but in actual use, the cross-section can be square or polygonal.

[0026] Specifically, in terms of usage, when the floor slab collapses and impacts the structure, the top 1 of the shock-absorbing bed, after receiving gravitational potential energy, rotates under the action of the fixed-axis bolt 3. Simultaneously, the top hook anti-detachment buckle 5 rotates synchronously. Under the pressure of the viscous damper 4 and the fixed-axis bolt 3, which increases the friction between the top 1 and the fixed axis 2, the top 1 of the shock-absorbing bed can buffer the gravitational potential energy applied to it by the floor slab. When the top 1 of the shock-absorbing bed rotates to a certain angle, the viscous damper is compressed to its limit, one side of the top 1 of the shock-absorbing bed touches the ground and stops rotating. The top hook anti-detachment buckle 5 engages with the anti-detachment buckle protrusion 8 on one side of the shock-absorbing bed column 6. At the same time, the top 1 of the shock-absorbing bed and the shock-absorbing bed column 6 form a 45° angle. After the top hook anti-detachment buckle 5 engages with the anti-detachment buckle protrusion 8, a relatively stable triangular structure is formed. The resulting slope can change the direction of force, dissipating the force of the floor slab impacting the structure, thereby improving the structure's survivability and providing greater space for survival. In normal times, mosquito nets can be hung on the top of the earthquake-resistant bed, combining practicality and decoration to meet people's daily needs.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
