This structure has the following defects: 1. The door leaf or window sash 71 is easy to be removed from the outside of the sliding door, and the anti-theft performance is poor; , lower door frame 72 causes thickness larger in order to accommodate door leaf or window sash 71, especially when door leaf or window sash 71 is installed composite glass, hollow glass, thickness is larger, causes upper and lower door frame 72 to be extremely heavy. The purpose of the present invention is to overcome the above disadvantages, and develop an attractive and reliable double-layer structure of sliding doors and windows.

Contents of the invention

In order to overcome the deficiencies of the prior art, the utility model provides a double-layer structure of a sliding door, which is small in size, reliable and durable, and more elegant in appearance.

The technical scheme that the utility model solves its technical problem adopts is:

A double-layer structure of a sliding door, including a movable door leaf, the upper and lower sides of the movable door leaf are provided with installation grooves, the installation grooves are connected with detachable guide aluminum grooves, and the guide aluminum grooves Rollers are connected to connect the door frame, the guide aluminum groove is snapped into the groove of the door frame, and the width of the movable door leaf is greater than the width of the groove of the door frame.

As an improvement of the above technical solution, the installation groove is set in a rectangular shape and L-shaped or T-shaped clips are provided on the two side walls, and the guide aluminum groove is provided with lugs that match the clips. The rear guide aluminum groove abuts against the bottom surface of the installation groove and its lugs are engaged with the clamping plate.

As a further improvement of the above technical solution, multiple sets of clamping plates are arranged along the height direction of the installation groove.

As a further improvement, the roller is connected with a roller seat, the guide aluminum groove is provided with a T-shaped slot for installing the roller seat, and the roller seat is provided with a block matching the T-shaped slot.

As a further improvement, the roller seat is fixedly connected to the guide aluminum groove through screws.

The beneficial effects of the utility model are: the guide aluminum groove of the movable door leaf is stuck in the groove of the door frame, the movable door leaf can be exposed as a whole, the appearance is complete and beautiful, and the decoration is improved; the movable door leaf is connected to the door frame through the detachable guide aluminum groove, and The width of the guide aluminum groove is smaller than that of the movable door leaf, which is beneficial to reduce the width of the door frame, simplify the structure and reduce the cost; the width of the movable door leaf is larger than the width of the groove of the door frame, and the detachable guide aluminum groove is used as the guide, which cannot be lifted upwards The movable door leaf cannot be disassembled from the outside, which eliminates the defect of the existing sliding door that the movable door leaf can be removed from the outside, and greatly improves the anti-theft performance.

detailed description

Referring to Figures 1 to 3, a double-layer structure of a sliding door includes a movable door leaf 1, the upper and lower sides of the movable door leaf are provided with installation grooves 11, and a detachable door is connected to the installation groove 11. The guide aluminum groove 2, the roller 3 is connected to the guide aluminum groove 2 to connect the door frame 4, the guide aluminum groove 2 is stuck in the groove 41 of the door frame 4, and the width of the movable door leaf 1 is larger than the groove of the door frame 4 41 width. Preferably, the installation groove 11 is set in a rectangular shape and L-shaped or T-shaped clamping plates 12 are arranged on both side walls, and the guide aluminum groove 2 is provided with lugs 21 matching the clamping plates 12, After assembly, the guide aluminum groove 2 abuts against the bottom surface of the installation groove 11 and its lug 21 engages with the clamping plate 12 to be fixed. In order to adapt to guide aluminum grooves 2 of different specifications, preferably, the clamping plates 12 are provided in multiple groups and arranged along the height direction of the installation groove 11 . Preferably, the roller 3 is connected with a roller seat 31, the guide aluminum groove 2 is provided with a T-shaped groove for installing the roller seat 31, and the roller seat 31 is provided with a block matching the T-shaped groove, and the The cooperating positioning roller seat 31 of the block and the T-shaped groove, the roller seat 31 is fixedly connected with the guide aluminum groove by screws. With the above structure, the movable door leaf is only inserted into the groove 41 of the door frame 4 by the guide aluminum groove 2, and the movable door leaf is exposed as a whole, with a complete and beautiful appearance, which improves decoration; the movable door leaf is connected to the door frame 4 through the detachable guide aluminum groove 2, And the width of the guide aluminum groove 2 is less than the width of the movable door leaf, which is beneficial to reduce the width of the door frame 4, simplifies the structure, and reduces the cost; Therefore, the movable door leaf 1 cannot be lifted upwards for disassembly, and the movable door leaf 1 cannot be disassembled from the outside, which eliminates the defect that the existing sliding door can disassemble the movable door leaf from the outside, and greatly improves the anti-theft performance.

The above is only a preferred embodiment of the utility model, but the utility model is not limited to the above-mentioned embodiment, as long as it achieves the technical effect of the utility model by any same or similar means, it should fall into the scope of the utility model within the scope of protection.
