Description

Technical Field

[0001] The utility model relates to the technical field of guide slide rails, and more specifically to a guide slide rail for a folding door. Background Art

[0002] Folding doors are beautiful, novel, and effectively save the space they occupy. Folding doors generally consist of door leaves, door frames, guide rails, etc. In folding doors, the guide rails are mainly fixed to the cabinet, floor or wall of the furniture to install the roller components, so as to realize the folding of the door leaves.

[0003] At present, during the installation of the guide rails of folding doors, in order to improve their aesthetics, the guide rails are often hoisted in installation grooves on the top of the cabinet or the top of the wall, and then connected to multiple door leaves through the installation components below them. During the hoisting process, although the multiple door leaves move along the bottom of the cabinet or the ground plane, the roller components in the guide rails are still pulled downward by the gravity of the door leaves. Moreover, the guide rails in the prior art are mostly single-layer designs, which are easily deformed under long-term force, thereby affecting the sliding of the roller components and further affecting the folding activities of the door leaves. Therefore, there is an urgent need to improve the technology of the guide rail structure to perfect this equipment.

[0004] Therefore, the utility model provides a guide slide rail for a folding door. Utility Model Content

[0024] Example:

[0025] See also Figure 1-3 A folding door guide rail comprises a lower rail 1 and an upper rail 2, the lower rail 1 and the upper rail 2 are connected to each other, a pair of reinforcing blocks 3 are fixedly connected between the inner walls of the upper rail 2, a moving block 4 is provided between the lower rail 1 and the upper rail 2, and a moving plate 5 is fixedly connected to the upper end of the moving block 4, a sliding mechanism 7 is installed between the moving block 4 and the moving plate 5 and the lower rail 1 and the reinforcing block 3, a connecting rod 6 is installed on the upper end of the moving plate 5, and a mounting plate 8 is installed on the upper end of the connecting rod 6.

[0026] During use of the present solution, firstly, the moving block 4 and the moving plate 5 are taken to drive the sliding mechanism 7 to penetrate into the gap between the lower track 1 and the upper track 2 along the gap between the lower track 1 and the upper track 2, so that the pair of hanging wheels 702 are located inside the lower track 1 and contact its inner wall, and at the same time, the pair of sliders 704 are respectively extended into the pair of slide grooves 705 and slidably connected therewith, and then the guide slide rails are driven to be installed in the reserved installation grooves, so that the lower track 1 and the upper track 2 are located in the installation grooves, and then the door leaf is taken to make the reserved holes on the door leaf correspond to the installation holes 801 on the installation plate 8 for installation, and then the door leaf is driven to enter through the connecting rod 6 and the external thread 9. When the door leaf is locked and fixed, and the door leaf is pulled to fold, a pair of hanging wheels 702 roll along the lower track 1, and at the same time a pair of sliders 704 slide in a pair of slide grooves 705 respectively, to achieve double motion assistance for the folding activity of the door leaf, thereby ensuring the stability of its folding activity and enhancing the use effect. In addition, the double-layer design guide slide rail composed of the lower track 1 and the upper track 2, combined with the connection reinforcement of a pair of reinforcement blocks 3, makes the overall structure of the guide slide rail more firm and stable. Compared with the single-layer design, it has better stability and is not easy to deform under the force of lifting, thereby ensuring the stable sliding of the sliding mechanism 7, thereby ensuring the stability of the door leaf folding activity.

[0027] See also Figure 1 and Figure 3The sliding mechanism 7 includes a mounting seat 701 fixedly connected to the lower end of the moving block 4, and the left and right ends of the mounting seat 701 are rotatably connected with hanging wheels 702.

The ends of a pair of reinforcement blocks 3 that are close to each other are each opened with a slide groove 705, and the slider 704 is located in the slide groove 705 and is slidably connected thereto.

[0028] During use of this solution, during the folding activity of the door leaf, the mounting plate 8 and the connecting rod 6 are driven to move, the connecting rod 6 drives the movable plate 5 and the movable block 4 to move, the movable plate 5 drives a pair of sliders 704 through a pair of side plates 703 to slide in a pair of slide grooves 705 respectively, to achieve movement inside the upper track 2, and at the same time the movable block 4 drives a pair of hanging wheels 702 to move inside the lower track 1 through the mounting seat 701, thereby achieving the dual movement inside the lower track 1 and the upper track 2 to assist and guide the folding activity of the door leaf, thereby ensuring the stability of its folding activity and enhancing the use effect.

[0029] See also Figure 3 The outer ends of a pair of hanging wheels 702 are provided with a high-strength wear-resistant layer.

[0031] See also Figure 1 and Figure 3 The outer end of the connecting rod 6 is provided with an external thread 9, and the external thread 9 is located on the upper side of the moving plate 5.

[0032] During use of this solution, the external thread 9 can be used to lock and fix the door leaf during installation.
