This utility model provides a highly stable shock-resistant table, relating to the field of table technology. The highly stable shock-resistant table includes table legs, with a horizontal buffer mechanism at the lower end of each leg. The horizontal buffer mechanism includes a base box, within which a movable tube is installed. At least three horizontal spring damping components are connected between the outer end of the movable tube and the inner wall of the base box. A sliding plate is connected to the lower end of the movable tube, ball bearings are installed in the bottom plate of the base box, and a sealing plate is connected to the upper end of the movable tube. This highly stable shock-resistant table, through the horizontal buffer mechanism, effectively reduces the lateral kinetic energy transmitted from the ground to the table legs. Through the vertical spring damping components, it effectively reduces the vertical kinetic energy transmitted from the table legs to the tabletop. The combined effect of the horizontal buffer mechanism and the vertical spring damping components gives the table a high degree of stability, providing users with a more stable and comfortable experience.

The invention provides a track body capable of ensuring the flexibility of the track body and preventing the up-and-down vibration of the rollers as much as possible when the rollers cross the protruding portions of the core bones. The track body is provided with core bones (10) embedded at substantially equal intervals in the track body (9) and rolling paths (12, 13) for the rollers arranged on both sides in the track width direction of the track body (9) on the side opposite the ground contact surface. The track body is provided with protruding portions (24-27) protruding from each core bone (10) to both sides in the track rotation direction and supporting each rolling path (12, 13) on both sides in the track rotation direction of each core bone (10). At least the tip end portions of each protruding portion (24-27) of each core bone (10) corresponding to each rolling path (12, 13) are arranged offset from each other in the track width direction within the width of each rolling path (12, 13). The tip end of the protruding portion (25) of one core bone (10) and the tip end of the protruding portion (26) of the other core bone (10) are arranged close to or overlapping each other in the track rotation direction.

The utility model discloses a small flange type coupler, relates to the technical field of flange type couplings, and aims to solve the problems that an elastic piece in an existing flange type coupler needs to be fixed between a connecting piece and two metal claw discs in the axial direction, and the elastic piece and an iron core also need to be connected through a rigid piece; and the radial buffering and damping effects are limited. The nylon frisbee is installed in the sealing plate and the sealing cover, a circle of the outer side of the nylon frisbee is provided with a plurality of nylon petals, the nylon petals and the nylon frisbee are integrally formed, elastic bodies are arranged between the nylon petals, a plurality of elastic bodies are arranged between the nylon petals, and the nylon petals and the nylon frisbee are integrally formed. A connecting sleeve is arranged in the middle of the elastic body.
