Abstract

The utility model relates to a drawer buffer, which comprises a buffer component, a slider, a slider seat and a spring, wherein the buffer component comprises a cylinder body, a piston and a piston bar, the piston comprises a piston body 1, a Y-shaped seal ring, a seal sleeve and a piston body 2, the Y-shaped seal ring and the seal sleeve are arranged between the piston body 1 and the piston body 2, a gas vent is arranged on an interface of the Y-shaped seal ring and the seal sleeve, and a gas guiding groove is arranged on the outer edge of the seal sleeve. When using, the utility model is arranged on a fixed guide of a drawer, when being acted by an external tension, the flow resistance of the air in the cylinder body is small, and the drawing is easy. When the drawer is closed and is acted by a thrust, because being pressed by the piston, the pressure of the air in a cavity of the rear portion of the cylinder body is increased, a reaction force is acted on the poison, thereby preventing the spring from releasing the thrust, slowing down a reset speed of a tension spring, and achieving a buffer effect of pushing the drawer.

Description

A kind of drawer buffer
Technical field
The utility model relates to the buffer unit that a kind of drawer pushes return automatically.
Background technology
Existing drawer pushes returning device automatically and realizes with single spring convergent force, when drawer is extracted out, finger stretches the coil spring that is in the normal state, when being stretched to the limit, positioner is located the spring extended state, when drawer is pushed into certain depth, finger is removed the spring positioning states, the spring convergent force just rapidly haul finger and drawer pushes return automatically, there is the shortcoming that vibration is strong and collision is loud in this device, and long-term fierce collision can cause each connector loosening, so its work is unreliable, product is not durable, thereby makes the class of product seem lower.
In order to reduce the collision between drawer and the cabinet, on some drawer buffer has been installed now, it is provided with a cylinder body on the slide rail of drawer, be provided with piston in the cylinder body, in piston, inject oil, by to the flow velocity that the circulate control of oil in cylinder body inner carrier both sides, make drawer when return, produce resistance, reach the collision of avoiding between drawer and the cabinet.But because when producing, when injecting oil in the cylinder body, inevitably can in cylinder body, leave some minute bubbles, bubble be mixed in the oil and when circulating, can produce " " the sound, can allow the user not feel well during use.
Summary of the invention
The purpose of this utility model is to provide a kind of Stability Analysis of Structures, the drawer buffer of silent in the use.
The utility model achieves the above object by following structure:
It includes Buffer Unit, slide block, take-up housing and spring, Buffer Unit one side is provided with U-lag, one end is provided with pipe joint, Buffer Unit connects a piston rod, piston-rod end is provided with joint, slide block top has U-shaped to dial hook, a hook is arranged at the bottom, there is guide finger at two ends, the take-up housing joint is connected with the Buffer Unit end fittings, has gathering sill, slide block to be installed in the take-up housing cannelure in the middle of the take-up housing, the two ends guide finger is inserted in the gathering sill of take-up housing, slide block is connected with joint with the piston rod end, and spring is installed in the U-lag of Buffer Unit, and an end is fixed in the bayonet socket of U-lag outer end, the other end is fixed in the take-up housing hook, and its improvement is: Buffer Unit includes cylinder body, piston, piston rod; Piston includes piston body one, y-shaped ring, sealing shroud, piston body two, and y-shaped ring and sealing shroud are installed between piston body one and the piston body two, and the contact-making surface of y-shaped ring and sealing shroud is provided with air slot, and the sealing shroud outer rim is provided with the air guide groove.
Owing to adopted said structure, the utility model is installed on the fixed guide of drawer when using, do the time spent being subjected to external tensile force, piston one, sealing shroud, y-shaped ring, piston two are together to the motion of pulling direction, in this process, y-shaped ring and sealing shroud are in released state all the time, air in the cylinder body strong point groove that enters piston two of air guide groove and the gap between y-shaped ring and the sealing shroud by the sealing shroud outer rim swimmingly flows into the cylinder body back cavity, air flow resistance in cylinder body is little, is easy to pull; When closing drawers is subjected to thrust, piston, sealing shroud, piston move along thrust direction, moment is that sealing shroud contacts the generation sealing function with y-shaped ring, at this moment, form negative pressure in the cylinder body front end chamber piston is produced pulling force, air in the cylinder body back side chamber is because of being subjected to the compression of piston, air pressure increases, piston is produced reaction force, stop spring to discharge the reset speed that pulling force slows down tension spring, slowly exit by the thin channel that the air guide groove of air slot on the y-shaped ring and sealing shroud outer rim is formed, reach the buffering effect that drawer pushes.
