Detailed Description

It should be noted that the embodiments and features of the embodiments of the present invention may be combined with each other without conflict.

In the description of the present invention, it is to be understood that the terms "central," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like are used in the orientation or positional relationship indicated in the drawings, which are merely for convenience in describing the invention and to simplify the description, and are not intended to indicate or imply that the referenced device or element must have a particular orientation, be constructed and operated in a particular orientation, and are therefore not to be construed as limiting the invention. In the description of the invention, the meaning of "a plurality" is two or more unless otherwise specified.

In the description of the invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted", "connected" and "connected" are to be construed broadly, e.g. as being fixed or detachable or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the creation of the present invention can be understood by those of ordinary skill in the art through specific situations.

The invention will be described in detail with reference to the following embodiments with reference to the attached drawings.

An elevator buffer with high buffer performance is disclosed, as shown in fig. 1 to 4, and comprises a base 1 and a top plate 2, wherein a buffer structure 3 is arranged at the upper part of the top plate, and a supporting mechanism 4 is arranged between the top plate and the base;

the buffer structure comprises a plurality of split bodies 5 which are arranged side by side, the two adjacent split bodies are connected with each other through a connecting body 6, a buffer reinforcing piece 7 is arranged in each split body, and a connecting piece 8 for connecting the buffer reinforcing pieces in the split bodies on the two sides is arranged in the connecting body; in an optional embodiment, the split body and the connecting body are integrally formed, specifically, the split body and the connecting body in the buffer structure are formed by vulcanization of a rubber material, and the structural stability is good.

The connector height is less than the components of a whole that can function independently height, forms deformation clearance 9 between two adjacent components of a whole that can function independently, promptly, the recess that forms between two components of a whole that can function independently receives the space of extrusion deformation, such structural design both can effectively guarantee components of a whole that can function independently bearing capacity, allows its compressive deformation under great load again, and shock-absorbing capacity is better, components of a whole that can function independently and connector lower surface all are equipped with buffering cavity 17, and the pressure that the air compression in the buffering cavity brought when utilizing the pressurized provides the supporting force, and compression degree is bigger, and buffering cavity internal pressure is bigger, and is more obvious to the "support" effect that the components of a whole that can. The buffer concave cavity is also used as a space for deformation of the split body or the connecting body after being pressed. In an optional embodiment, the buffering cavity can be vertically provided with a spring, and when the spring is pressed, the spring can play a role in buffering, so that the buffering performance is further improved.

The buffering reinforcing part comprises a horizontal bearing part 10, and two ends of the bearing part are respectively provided with a downward inclined supporting part 11; the two ends of the connecting piece are respectively connected with the tail ends of the supporting parts on the corresponding sides.

In an alternative embodiment, the supporting mechanism comprises a cylinder 12 with an opening at the lower end, a spring 13 is arranged in the cylinder, the upper end of the spring is propped against the cylinder, and the lower end of the spring is propped against the base; the outer wall of the barrel is symmetrically provided with edge blocks 14, and the base is provided with guide columns 15 matched with the guide holes in the edge blocks. The cylinder is generally fixed to the lower end surface of the top plate. The guide column is utilized to guide the cylinder body, so that the cylinder body can always move in the vertical direction.

In order to further improve the buffering capacity and avoid the direct collision of the base or the top plate with the cylinder, a buffering block 16 is arranged at the lower end of the cylinder, and a through hole avoiding the spring is arranged on the buffering block. The buffer block can be a rubber block or a nylon block.

Of course, the support mechanism described above comprises several sets of spring cylinders arranged vertically, as shown in fig. 1. The cylinder end of the spring cylinder can be fixed on the base, and the cylinder rod end is fixed on the top plate.
