Description

Novel lower rail structure of sliding door and window

Technical Field

The utility model relates to a door and window structural design technical field, the concrete design is a novel rail structure under sliding door.

Background

The structure of the lower rail of the existing sliding door and window mainly comprises two types: one is a lower rail bottom surface smooth structure, the structure is simple in design, but the smooth structure has strict requirements on the installation of doors and windows and has overhigh requirements on the flatness of the contacted bottom surface, otherwise, the installed lower rail is easy to deform under the action of the gravity of a door leaf, so that the service life of the doors and windows is shortened; the other is that the bottom surface of the lower rail is provided with a convex profile supporting leg which can reduce the contact area of the whole lower rail and the ground, however, when small unevenness exists between the supporting legs of the lower rail, the lower rail is easy to vibrate in the opening and closing process of the door, so that noise is generated; nor barrier properties.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a novel rail structure under sliding door, specific technical scheme is:

the utility model provides a novel rail structure under sliding door, comprises a base plate, bottom plate both sides edge level smooth bend downwards becomes vertical form, and the tip is equipped with the first backup pad of inside extension, the bottom plate lower surface is close to smooth bending position and is equipped with the screw mounting mouth, be equipped with the reinforcing plate perpendicularly in the middle of the bottom plate lower surface, reinforcing plate one end fixed connection bottom plate, other end fixed connection second backup pad, all be equipped with the mounting groove between reinforcing plate and the both sides screw mounting mouth, the mounting groove includes upper groove and low groove, install the rail in the upper groove, install the adhesive tape in the low groove.

Furthermore, limiting strips are symmetrically arranged in the upper groove.

Furthermore, limiting plates which are bent upwards are arranged on notches on two sides of the upper groove, and the limiting plates are in contact with the steel rail.

Furthermore, the notch of the lower groove is provided with a hook protruding inwards.

Furthermore, the adhesive tape is T-shaped, the width of the bottom of the adhesive tape is the same as that of the lower groove, and the adhesive tape is provided with a through hole.

Furthermore, the top of the rubber strip is provided with a convex strip corresponding to the hook.

The utility model has the advantages that:

1. the structure of the adhesive tape arranged on the bottom surface of the lower rail can convert the vibration generated by the sliding door into the fluctuation of the adhesive tape, so that the basic functions of the sliding door are met, and the performances of shock resistance and water seepage prevention are realized;

2. the utility model discloses simple structure, the installation condition requirement is not high, can adapt to the installation ground under the different environment, very big extension sliding door's life.
