Description

A kind of sliding door without suspension rail and bottom rail

technical field

The invention belongs to the technical field of door and window manufacturing, and relates to a sliding door structure, in particular to a sliding door without hanging rails and bottom rails.

Background technique

The four-door type sliding door currently used, structurally, the sliding door is respectively that the upper part of the door frame adopts a suspension rail, or the lower part of the door frame adopts a guide rail to realize the movement and closing of the sliding door. Due to the large structure and heavy weight of the door body, the upper part of the door frame adopts a sliding door with hanging rails. After a period of use, the connected rolling wheel shaft on the sliding door tends to loosen or even fall off during the load-bearing movement, so it is extremely unlikely. Safety; while the lower part of the door frame adopts guide rails, and the lower part of the door body is equipped with frames and guide rails. When the sliding door is opened, whether it is higher than the ground or lower than the ground, the frame and guide rails under the door will catch people passing by if they are not careful. To stumble and become an unsafe obstacle.

Contents of the invention

The object of the present invention is to provide a sliding door without suspension rails with simple and reasonable structure, convenient assembly and safety, which solves the above-mentioned problems existing in the existing sliding doors.

The technical scheme adopted in the present invention is a sliding door without hanging rail and lower rail, including a door frame, two fixed doors and two sliding doors, the door frame is composed of an upper horizontal frame and two side frames, the Two sets of sliding guide rails are formed in the groove of the upper horizontal frame, and two sets of door seals are protruded on the inner surface of the two sides of the frame; under the two fixed doors of the door frame, there is a corresponding section with two tracks on the surface. The slide rail is installed in the door frame through the groove provided on the fixed door frame. There are two inner and outer rollers on the side, the inner roller is installed in contact with the slide rail, and the outer roller is installed in contact with the ground.

The sliding door without suspension rail and without lower rail according to the present invention is also characterized in that:

The inner side of the frame of the fixed door and the sliding door is also provided with a glass installation groove, and the installation groove is equipped with double-layer vacuum glass.

The inside of the frame of the fixed door and the sliding door is provided with a glass installation groove, and the glass installation groove is equipped with a transition groove, and a single layer of glass is installed in the transition groove.

Butt bars are also installed in the groove of the sliding door-frame.

When the fixed door and the sliding door are closed, the butt joint parts are provided with protruding snap-in bodies.

The present invention has no suspension rail and no lower rail sliding door. Through two sets of sliding guide rails in the horizontal frame groove on the door frame, two sets of door seals are protruded on the inner surface of the frame on both sides, and the slide rails installed under the door frame fix the two doors. The door and two sliding doors are installed in it. Since the moving track of the two sliding doors is only installed at the position below the fixed door, the rollers on the inner side of the lower end of the sliding door fall on the slide rail under the fixed door of the door frame, and the outer rollers directly It falls on the ground, so when opening or closing the sliding door, the sliding door is guided by the sliding guide rail of the upper horizontal frame of the door frame and the sliding rail below the fixed door, and is supported by the rollers on the inner and outer sides of the lower end of the sliding door to move smoothly.

The bottom of the door frame of the present invention has only some rails on both sides. When the door is opened, there is no track obstacle on the ground in the middle of the sliding door, and there are no unsafe factors. Therefore, unexpected dangers will not be caused when people pass the sliding door.

Detailed ways

The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

A sliding door without hanging rail and lower rail, as shown in Fig. 1, Fig. 2 and Fig. 3, comprises a door frame 1, two fixed doors 2 and two sliding doors 3, and the door frame 1 is composed of an upper horizontal frame 11 and two side frames 12, two sets of sliding guide rails 4 are formed in the groove of the upper horizontal frame 11, and two sets of door seals 5 are protruded on the inner surface of the two side frames 12; two fixed doors 2 on the door frame 1 The bottom of each section is equipped with slide rails 6 with two tracks on the surface, and the fixed door 2 is installed in the door frame 1 through the groove 7 provided by the frame of the fixed door 2, and the two sliding doors 3 The groove 7 provided on the upper frame is installed on the sliding guide rail 4 in the upper horizontal frame 11 of the door frame 1, and the left and right sides of the lower frame are equipped with two inner and outer rollers 8, 9, wherein the inner roller 8 and the sliding rail 6 form a Contact installation, the rollers 9 on the outside are installed in contact with the ground; the inside of the frame of the fixed door 2 and the sliding door 3 is also provided with a glass installation groove 10, and the installation groove 10 is equipped with double-layer vacuum glass 13.

For the environment that does not need heat preservation and sound insulation, the double-layer vacuum glass 13 can not be installed in the installation groove 10, as long as the transition groove 14 is loaded onto in the glass installation groove 10, then the single layer glass 17 is installed in the transition groove 14 and gets final product.

The present invention has no suspension rail and no lower rail sliding door, through two sets of sliding guide rails 4 in the upper horizontal frame 11 of the door frame 1, two sets of door seals 5 are protruded on the inner surface of the two sides of the frame, and the slide rails 6 installed under the door frame , two fixed doors 2 and two sliding doors 3 are installed therein, since the moving track 6 of the two sliding doors 2 is only installed at the position below the fixed door 2, the roller 8 on the inner side of the lower end of the sliding door 3 falls on the door frame 1 On the slide rail 6 below the fixed door 2, the rollers 9 on the outside of it directly fall on the ground, so when the sliding door 3 is opened or closed, the sliding door 3 is guided by the sliding guide rail 4 of the upper horizontal frame 11 of the door frame and the sliding guide rail 4 of the lower horizontal frame 11 of the fixed door. The slide rail 6 is used as a guide, and the rollers 8 and 9 on both sides inside and outside the lower end of the sliding door 3 move as a support.
