Description

Technical Field

[0001] This utility model relates to the technical field of sliding door installation accessories, specifically to an improvement on the connection mechanism of a bottom-trackless sliding door. Background Technology

[0002] Traditional sliding doors typically include an upper track and a lower track to ensure stable sliding of the door panel. However, the lower track easily accumulates dust and debris, causing the door panel to slide obstructed and posing a tripping hazard. This is especially true in public places and homes with children or the elderly, where the safety of lower-track sliding doors is lower. However, existing trackless sliding doors, when subjected to excessive force on the upper track, are prone to sagging or even falling, causing safety issues during use. Furthermore, the lack of positioning blocks on the ground makes the sliding door prone to wobbling during movement, resulting in poor stability. Utility Model Content

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a multi-panel sliding door connection mechanism without a bottom track is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-7 As shown, a multi-panel sliding door connection mechanism without a bottom track according to an embodiment of the present utility model includes a door frame profile 1, a guide plate 2, a roller assembly 3 and a connector 4. The guide plate 2 is fixed on the ground, and the roller assembly 3 is installed inside the door frame profile 1, which is responsible for supporting the weight of the door and rolling during opening and closing to reduce friction and ensure smooth sliding of the door. The door frame profile 1 is provided with an installation area 11, a guide groove 12, and a roller mounting groove 13. The installation area 11 is located on the top of the door frame profile 1. The guide groove 12 and the roller mounting groove 13 are located on the lower side of the installation area 11. Two sets of guide grooves 12 are located on both sides of the roller mounting groove 13. The guide plate 2 is provided with a positioning plate 21. A guide wheel 22 is connected to the positioning plate 21. The guide wheel 22 is tumbling in the guide groove 12. The connector 4 is connected to the outside of the door frame profile 1 by screws. The connector 4 is provided with a second guide wheel 41 and an adjustment hole 42. The adjustment hole 42 is located on the longitudinal block surface of the connector 4. The second guide wheel 41 is located on the lower side of the connector 4. The second guide wheel 41 is tumbling in the guide groove 12.

[0028] In one embodiment, the door frame profile 1 is provided with an array of elements, with two sets of door frame profiles 1 connected by a guide plate 2, and multiple sets of door frame profiles 1 combined and connected with connectors 4 via guide plates 2. This enables the installation of two or more sliding doors, making it more versatile.

[0029] In one embodiment, the positioning plate 21 is fixedly connected to the ground, and the two sets of guide wheels 22 slide correspondingly within the guide grooves 12. This allows the door frame profile 1 to roll during opening and closing, reducing swaying and ensuring smooth sliding of the door.

[0030] In one embodiment, a gap is left between the outer side plate of the guide groove 12 and the guide plate 2 and the connector 4. This reduces the possibility of the door frame profile 1 colliding with the guide plate or connector 4 during pushing and pulling.

[0031] In one embodiment, the roller assembly 3 includes a slide rail bracket 31, a load-bearing roller assembly 32, an annular groove 33, positioning strips 34, and protrusions 36. The positioning strips 34 are disposed inside the slide rail bracket 31, and a positioning pin 35 is connected to the middle of the positioning strips 34. The positioning pin 35 is inserted into the annular groove 33, which is disposed on the slide rail bracket 31. The protrusions 36 are fixedly connected to the inner side of the array of positioning strips 34, and an adjusting block 37 is engaged within the protrusions 36. The array of load-bearing roller assemblies 32 are respectively installed at both ends of the positioning strips 34. This solves the problem of the door not easily sagging and also allows the height of the load-bearing roller assembly 32 to be adjusted, realizing the adjustment of the door's height and angle.

[0032] In one embodiment, the door frame profile 1 is further provided with mounting holes 14, which are pre-drilled holes. This allows for quick and accurate assembly during on-site installation. The door frame profile 1 is assembled to form an installation frame, and the connector 3 is installed on the door frame profile 1.

[0033] In one embodiment, metal or wooden doors and windows can be installed in the installation area 11, providing applicability and flexibility for doors and windows made of different materials.

[0034] Working principle: The roller assembly 3 is installed in the installation area 11 of the door frame profile 1. The guide plate 2 can be attached to the ground with screws and strong adhesive. Two sets of door frame profiles 1 are connected by the guide plate 2, and multiple sets of door frame profiles 1 are connected by the guide plate 2 and the connector 4. This allows for the installation of two or more sliding doors, making it more versatile. The outer side plate of the guide groove 12 is spaced from the guide plate 2 and the connector 4. This reduces the chance of the door frame profile 1 colliding with the guide plate or connector 4 during sliding, and also allows the door body formed by the door frame profiles to move smoothly without shaking.
