Description

Technical Field

[0001] This utility model relates to the field of concealed wooden door technology, and in particular to a concealed movable wooden door. Background Technology

[0002] With rapid urbanization and increasingly scarce urban land resources, small and medium-sized apartments have become the mainstream. The scarcity of living space has led to higher demands for space utilization. Traditional hinged doors require a certain amount of space when opened, while sliding doors, although space-saving, still create a visual disconnect due to the track and the door itself. These issues are particularly prominent in small living environments. For example, if a hinged door is used in a small bedroom, it will conflict with the space occupied by the bed, wardrobe, and other furniture when opened. If the partition door between the kitchen and living room is a sliding door, the track and the door itself will disrupt the integrity of the space, making the already limited space feel even more cramped. The emergence of concealed sliding wooden doors has provided a basis for the practicality of space.

[0003] However, existing hidden doors typically use a top sliding mechanism to assist the lower wooden door in sliding. Since the current top sliding module is usually a sliding sleeve structure, and the bottom of the wooden door is usually not fitted with a track for auxiliary stopping for aesthetic purposes, after long-term use, the weight of the wooden door will cause the top sliding sleeve structure to shift left and right during translation. This shift can cause the top track to fall off, creating a corresponding safety hazard.

[0004] Therefore, we provide a hidden sliding wooden door to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a concealed movable wooden door to solve the problems mentioned in the background art.

[0010] Compared with the prior art, the beneficial effects of this utility model are: As shown in the figure, the top of this utility model features a hidden sliding door panel assembly. The internal sliding slider is connected to the sliding groove via an internal rotating sleeve wheel. A rubber friction strip for auxiliary deceleration is horizontally attached inside the sliding groove, increasing the friction between the rotating sleeve wheel and the sliding groove during translation. This prevents the door from being unable to stop due to its own weight. A bottom fixing and positioning assembly is installed at the bottom of the door, along with a magnetic auxiliary positioning assembly. During use, the translation distance of the door is limited by the bottom fixing and positioning assembly. The corresponding first and second magnetic rings operate on a repulsive principle, further preventing left-right deviation during translation when the door is about to reach a critical distance.

The fixed support assembly 21 is located on the lower side of the fixed wall 1. The sliding door panel assembly 22 is located on the surface of the fixed support assembly 21. The magnetic auxiliary positioning assembly 23 is located at the lower end of the sliding door panel assembly 22. The bottom fixed positioning assembly 24 is located below the magnetic auxiliary positioning assembly 23. The fixed support assembly 21 includes a fixed connecting top rod 211, an edge limiting sleeve 212, a damping rubber pad 213, a sliding groove 214, and a rubber friction strip 215. The fixed wall... The lower ends of both sides of body 1 are threaded with fixed connecting rods 211. One side of the fixed connecting rods 211 is fixedly connected with an edge limiting sleeve 212. The inner side of the edge limiting sleeve 212 is fitted with a damping rubber pad 213. The inner side of the edge limiting sleeve 212 is fixedly connected with a translational slide 214. The inner side of the translational slide 214 is bonded and fixed with a rubber friction strip 215. As shown in the figure, damping rubber pads 213 are installed at the contact points between the translational slide 214 and the two ends of the rotating sleeve wheel 222, which can prevent the rotating sleeve wheel 222 from directly contacting the edge limiting sleeve 212, thereby preventing the edge from falling off.

[0014] Furthermore, the sliding door panel assembly 22 includes a sleeved sliding slider 221, a rotating sleeve wheel 222, and a fixed door panel 223. The sleeved sliding slider 221 is slidably sleeved on the surface of the sliding groove 214. The sleeved sliding slider 221 is slidably connected to the sliding groove 214 through the rotating sleeve wheel 222 inside. The fixed door panel 223 is fixedly connected to the bottom of the sleeved sliding slider 221. The inner sleeved sliding slider 221 is slidably connected to the sliding groove 214 through the inner rotating sleeve wheel 222. In addition, a rubber friction strip 215 for auxiliary deceleration is horizontally adhered inside the sliding groove 214 to increase the friction between the rotating sleeve wheel 222 and the sliding groove 214 during the translation process, and to prevent the wooden door from being unable to stop due to its own weight.

[0015] Furthermore, the magnetic auxiliary positioning component 23 includes a first magnetic base 231 and a first magnetic ring 232. The lower end of the fixed door panel 223 is fixedly connected to the first magnetic base 231, and the first magnetic ring 232 is fixedly connected to one side of the first magnetic base 231.
