Description

TECHNICAL FIELD

[0001] The utility model relates to door and window section structure technical field, concretely is a hidden frame lower rail structure of heavy sliding door. BACKGROUND

[0002] In the field of building decoration, the design and structure of doors and windows play a crucial role in the overall aesthetics, practicality and functionality of the building. Heavy sliding doors are widely used in various large-scale architectural spaces, such as shopping malls, exhibition halls, villas and other places, due to their ability to withstand heavy loads and good sliding performance.

[0003] Traditional heavy sliding door rail structures have some obvious shortcomings. First, in terms of aesthetics, the common lower rail structure usually has a relatively obvious frame, which will visually destroy the coherence and integrity of the entire space, and cannot meet the pursuit of simple and smooth appearance in modern architectural design. Especially in some high-end architectural projects, owners and designers prefer door and window structures with hidden frame effects to create a more open and transparent visual experience.

[0004] Secondly, from the perspective of practicality, the sealing and stability of the traditional rail structure are not good. Due to the existence of the frame, dust and debris are easily accumulated, which not only affects the smoothness of the rail sliding, but also may cause the rail to wear out and shorten its service life. Moreover, in the long-term use process, the connecting part between the door leaf and the rail is prone to looseness, which affects the normal use of the door and may even pose a safety hazard.

[0005] In order to solve the above problems, some improved rail structures have appeared in the market, but most of them still have problems such as complex structure, difficult installation, high cost, etc., which cannot be widely promoted in practical application. INVENTION CONTENTS

[0038] The heavy-duty sliding door hidden frame lower rail structure realizes the hidden frame effect by setting the adapter profile 4 and the filling area 5, specifically, the adapter profile 4 is located between the lower rail profile 1 and the door leaf profile 3, is connected to the lower rail profile 1, and in the vertical projection, the part of the lower rail profile 1, except the slide 2, is located in the projection range of the filling area 5 of the adapter profile 4, after filling the filling material 16, such as marble or wood floor, which is consistent with the ground decoration material, in the filling area 5, from the top, the filling material 16 is integrated with the ground decoration material, and the lower rail profile 1 is shielded by the filling material 16 of the filling area 5, so that the lower rail structure presents the effect of the hidden frame (except the position of the slide 2) in the vision, meets the pursuit of simple and smooth appearance in modern architectural design, and enhances the spaciousness and permeability of the space.

[0039] Furthermore, after the filling material 16 fills the filling area 5 of the adapter profile 4, the overall structure effectively shields the traditional rail frame, not only achieves the hidden frame effect, but also builds a barrier to block foreign matters, for example, in the daily environment, dust, small gravel and other foreign matters are easy to scatter everywhere under the driving of air flow or personnel activity, at this time, the filled adapter profile 4 can greatly reduce the probability of foreign matters directly entering the inside of the rail, reduces the accumulation of foreign matters in the rail gap, and further ensures the smooth sliding of the door leaf.

[0040] In summary, after the filling area 5 is filled with marble, wood floor and other materials which are consistent with the ground decoration material (it can also be inconsistent, depending on the selection of the user), the lower rail profile 1 is effectively shielded, the protruding frame of the traditional rail is eliminated, the heavy-duty sliding door can better integrate into the surrounding environment, and an open and transparent visual feeling is brought to the architectural space, which is highly consistent with the strict requirements of modern architecture, especially high-end projects, for beauty, and greatly improves the overall color value of the building.
