Abstract

The utility model discloses a double-track sliding door which comprises an upper border, a lower border, two upper door frames and two lower door frames, wherein two guides are arranged below the upper border; the upper edges of the two upper door frames are located in the guides respectively; two tracks are fixed on the lower border; two slide grooves located on the tracks are formed below the lower door frames; vibration dampers are arranged between the slide grooves and the lower door frames; an internal clamp groove and an external clamp groove are formed at contact places between the upper door frames and the guides respectively; clamp grooves are formed at contact places between the upper border and the upper door frames; ethylene-propylene diene copolymer strips are clamped in the clamp grooves respectively. The double-track sliding door is good in sealability, the vibration dampers are arranged between the lower door frames and the slide grooves, so that a swing prevention effect can be exerted on sliding between the tracks and the slide grooves, and the noise is low.

Description

A kind of double-track sliding door

[technical field]

The utility model relates to window technology field, relates in particular to a kind of double-track sliding door.

[background technology]

Double-track sliding door of the prior art comprises frame and doorframe, is provided with two rails on lower frame, and the chute that these two doorframes are established below is positioned on this rail, but there is no seal approach between this doorframe and frame, poor sealing; And the rail push-and-pull between doorframe and frame is rocked, noise is large.

[utility model content]

The utility model provides a kind of double-track sliding door, and its good airproof performance is provided with vibration absorber between doorframe and chute, and push-and-pull is stable, noise is little.

The technical solution of the utility model is:

A kind of double-track sliding door comprises upper side frame, lower frame, two upper door frames and two lower door frames, on top is provided with two guide rails below frame, and the upper edge of these two upper door frames lays respectively in this guide rail, is fixed with two rails on lower frame;

Be provided with two chutes that are positioned on rail below lower door frame, also be provided with vibration absorber between this chute and lower door frame, and be respectively equipped with inside and outside two draw-in grooves in the place that upper door frame contacts with guide rail, on top the place that contacts with upper door frame of frame also is provided with draw-in groove, is arranged with respectively the Ethylene Propylene Terpolymer adhesive tape in this draw-in groove.

Double-track sliding door of the present utility model, be respectively equipped with inside and outside two draw-in grooves in the place that upper door frame contacts with guide rail, on top the place that contacts with upper door frame of frame also is provided with draw-in groove, be arranged with respectively the Ethylene Propylene Terpolymer adhesive tape in this draw-in groove, adopt the sealing of Ethylene Propylene Terpolymer adhesive tape, good seal performance between upper door frame and upper side frame; Also be provided with in addition vibration absorber between lower door frame and chute, can play the anti-shake effect to the slip between rail and chute, noise is little.
