Description

Synchronous hidden slide rail

technical field

The invention belongs to the technical field of slide rails, and relates to a synchronous hidden slide rail.

Background technique

The slide rail is generally used to be fixed on the cabinet body of the furniture. It is a hardware connection part for the drawer or cabinet board of the furniture to move in and out. The slide rail is suitable for the drawer connection of wooden and steel drawer furniture such as cabinets, furniture, office cabinets, and bathroom cabinets. When the existing three-section slide rails are in use, when the upper and outer rails are pulled out for nearly half of the stroke, it should be that when the upper and outer rails hit the middle rail, there will be a loud noise; for some drawers with larger widths, when the drawers are pulled out , there will be shaking problems.

Contents of the invention

In view of the above problems, the present invention provides a synchronous hidden slide rail, which can effectively avoid the sound of hitting the middle rail when the upper and outer rails are pulled out.

According to the technical solution of the present invention: a synchronously concealed slide rail, including a middle rail, the upper part of the middle rail is slidably provided with an upper outer rail, and the lower part is slidably provided with a lower outer rail. Synchronous pulley, the other end rotates to set the second synchronous pulley, the first synchronous pulley and the second synchronous pulley are tensioned and set the synchronous belt; the rear side of the upper outer rail is fixed with the first synchronous belt fastener , the first synchronous belt fastener is tightly connected with the synchronous belt; the front side of the lower outer rail is fixed with a second synchronous belt fastener, and the second synchronous belt fastener is tightly connected with the synchronous belt.

As a further improvement of the present invention, the circumferential surfaces of both the first synchronous pulley and the second synchronous pulley are tooth-shaped structures, and the circular arc tooth shape uniformly distributed on the inner ring of the synchronous belt is the same as that of the first synchronous pulley and the second synchronous pulley. Timing pulley meshes.

The hidden slide rail realizes the function that the upper outer rail and the middle rail move together, eliminates the sound of the upper outer rail hitting the middle rail when it is pulled out for nearly half the stroke, and realizes the upper outer rail, the middle rail and the lower outer rail of a single slide rail. synchronous movement of the rails.

The second object of the present invention is to provide a slide rail set to realize the synchronous movement of the left and right slide rails, which greatly reduces the problem that the drawer shakes when pulled out due to the wide drawer, and also avoids the upper outer rail when pulled out The sound of hitting the middle rail.

The technical solution to solve the above-mentioned second technical problem is to include two synchronous hidden slide rails as claimed in claim 1, the two synchronous hidden slide rails are connected by connecting rods, and the two ends of the connecting rods are respectively arranged on the corresponding first In the center hole of a synchronous pulley.

The slide rail set not only realizes the synchronous movement of a single slide rail, but also realizes the synchronous movement of the left and right slide rails, which greatly reduces the problem that the drawer shakes when it is pulled out due to the wide drawer, and also avoids the The sound of the upper outer rail hitting the middle rail.

detailed description

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

1 to 5, including the lower outer rail 1, the middle rail 2, the upper outer rail 3, the first synchronous belt fastener 4, the second synchronous belt fastener 5, the synchronous belt 6, the first synchronous pulley 7, Second synchronous pulley 8, connecting rod 9 etc.

As shown in Figures 1 to 3, the present invention is a synchronous hidden slide rail, comprising a middle rail 2, the upper outer rail 3 is slidably arranged on the upper part of the middle rail 2, the lower outer rail 1 is slidably arranged on the lower part, and the side of the middle rail 2 One end rotates to set the first synchronous pulley 7, and the other end rotates to set the second synchronous pulley 8, and the first synchronous pulley 7 and the second synchronous pulley 8 are tensioned to set the synchronous belt 6; The first synchronous belt fastener 4 is fixed on the side of the upper part, and the first synchronous belt fastener 4 is tightly connected with the synchronous belt 6; the front side of the lower outer rail 1 is fixed with the second synchronous belt fastener 5, and the first Two synchronous belt fasteners 5 are tightly connected with the synchronous belt 6.

Both the circumferential surfaces of the first synchronous pulley 7 and the second synchronous pulley 8 are tooth-shaped structures, and the evenly distributed arc tooth shape of the inner ring of the synchronous belt 6 is in phase with the first synchronous pulley 7 and the second synchronous pulley 8. engage.

Realize the function that the upper outer rail 3 and the middle rail 2 move together, eliminate the sound of the upper outer rail 3 hitting the middle rail when it is pulled out for nearly half of the stroke, and realize the upper outer rail 3, the middle rail 2 and the lower rail of a single slide rail. Synchronous movement of outer rail 1

As shown in Figures 4 and 5, a slide rail group includes two synchronously hidden slide rails as claimed in claim 1, the two synchronously hidden slide rails are connected by a connecting rod 9, and the two ends of the connecting rod 9 are respectively Set in the central hole of the corresponding first synchronous pulley 7.

The slide rail set not only realizes the synchronous movement of a single slide rail, but also realizes the synchronous movement of the left and right slide rails, which greatly reduces the problem that the drawer shakes when it is pulled out due to the wide drawer, and also avoids the The sound of upper outer rail 3 hitting middle rail 2.
