Description

Technical Field

[0001] The utility model relates to the technical field of shock-absorbing supports, in particular to a special sleeve for high-strength building shock-absorbing supports. Background Art

[0002] In high-strength building structures, shock-absorbing bearings play a vital role, which can effectively reduce the impact of external shocks such as earthquakes on buildings and improve the seismic resistance and safety of buildings. The spring is in the sleeve, and the special sleeve can effectively transfer the force borne by the shock-absorbing bearing to the building structure or support system to ensure the normal operation of the shock-absorbing device. Since the spring will generate rebound force after being compressed by external force, and the existing sleeve has limited effect on reducing the rebound force of the spring, the additional vibration and impact caused by the rebound force generated by the spring will accelerate the wear of the sleeve and other components, thereby reducing the service life of the shock-absorbing bearing.

[0006] Preferably, the sliding ball does not contact the top wall and the bottom wall in the spiral groove when no external force is applied, and the top wall and the bottom wall in the spiral groove are respectively provided with a rough surface and a transmission surface.

[0020] 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.

[0021] A special sleeve is a tubular part used to connect and fix different parts, usually made of metal or plastic. In building structures, special sleeves are often used in the connection parts of shock-absorbing bases, playing an important role in transmitting force, shock absorption and buffering, and coordination stability.

[0022] In terms of special sleeve technology, as the requirements for seismic performance of building structures increase, the application of patented sleeves on shock-absorbing bases becomes increasingly important.

[0023] Embodiment 1:

[0024] Combination Figure 1-Figure 3 As shown, the utility model provides a special sleeve for a high-strength building shock-absorbing support, including a sliding sleeve 101 and a sliding column 102 installed on the shock-absorbing base. The sliding sleeve 101 is slidably connected to the outside of the sliding column 102. A cavity 103 for accommodating a spring is opened at the bottom of the sliding column 102. A transmission member 200 is provided in the sliding sleeve 101 for reducing the rebound force generated after the spring on the sliding column 102 is compressed. Reducing the rebound force can make the spring reset process smoother, and the stable movement state can improve safety.

[0025] When the shock-absorbing base receives external force and the spring is compressed, the spring will generate rebound force, causing the shock-absorbing base to continue to vibrate. This rebound effect may affect the shock-absorbing effect and even cause instability of the building structure. The transmission member 200 includes a spiral groove 201 provided on the inner wall of the sliding sleeve 101, and a sliding ball 202 is fixedly connected to the sliding column 102 and is slidably connected to the spiral groove 201. The friction force of the top wall in the spiral groove 201 is greater than the friction force of the bottom wall. When subjected to external force, the sliding column 102 will compress the spring that moves downward, and the sliding ball 202 moves with the sliding column 102. Due to the provision of the spiral groove 201, the sliding ball 202 will slide along the spiral groove 201, which can reduce the force on the sliding column 102 and reduce the load on the spring, which can effectively improve the shock-absorbing effect and stability of the system, and improve the reliability and durability of the system.

[0026] The shock absorbing effect of the spring usually depends on the frequency of the vibration. In certain frequency ranges, the spring may not provide sufficient shock absorbing effect, resulting in the transmission of vibration to the building structure. The sliding ball 202 does not contact the top wall and the bottom wall in the spiral groove 201 when no external force is applied. The top wall and the bottom wall in the spiral groove 201 are respectively provided with a rough surface 204 and a transmission surface 203. When the sliding column 102 descends, the sliding ball 202 contacts the transmission surface 203. When the sliding column 102 is reset and rises, the sliding ball 202 contacts the rough surface 204. By designing the characteristics of the transmission surface 203 and the rough surface 204, the motion trajectory and speed of the system can be adjusted to achieve the desired functions and effects.

[0027] According to the embodiment, the design of the spiral groove 201 can reduce the force on the sliding column 102, thereby reducing the load on the spring. This design can play a role in shock absorption and buffering, so that the system can move more smoothly when subjected to external force and reduce the impact force on the spring.

[0028] Embodiment 2:

[0029] Combination Figure 1-Figure 3 As shown, based on the first embodiment, the rough surface 204 is made of felt material, which can slow down the movement speed of the ball.

[0030] Specifically, the transmission surface 203 is made of flannel material, and the friction force of the flannel material is smaller than the friction force of the felt.

[0031] Furthermore, when the sliding column 102 moves downward, the sliding ball 202 contacts the transmission surface 203, and when the sliding column 102 is reset and moves upward, the sliding ball 202 contacts the rough surface 204, which can realize the transmission function and transfer the force to other components, thereby realizing the movement of the system. At the same time, this contact can also play a shock-absorbing role, reduce the impact force on the system, and protect the equipment and structure.

[0032] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
