[0028] According to an embodiment of the present utility model, a position limiting connection mechanism for a sliding door without a lower rail is provided.
[0029] Example 1
[0030] like Figure 1-5As shown, according to an embodiment of the present invention, a limit connection mechanism for a sliding door without a lower rail comprises a door frame profile 1, a guide member 2 and a pulley assembly 3. The door frame profile 1 is provided with a limit block 11 and a guide groove 12. The guide groove 12 is located on the side of the limit block 11. The pulley assembly 3 is installed in the limit block 11 and connected to the top profile. The guide member 2 is set on the ground. The guide member 2 is provided with a positioning plate 21. The positioning plate 21 is connected to a guide wheel 22. The guide wheel 22 is connected to the guide groove 12 in a rolling manner. The bottom of the guide wheel 22 is connected to a screw rod. The guide wheel 22 is connected to the upper end of the screw rod in a rolling manner. The other end of the screw rod is fixedly connected to the positioning plate 21. In this way, the sliding connection of the two sets of sliding doors is achieved, and the guide wheel 22 on the guide member 2 corresponds to the guide groove 12.
[0031] like Figure 1-5 As shown, the door frame profile 1 is further provided with a limit block and a mounting hole. The limit block is located above the limit block 11 , and the mounting hole is located above the guide groove 12 .
[0032] like Figure 1-5 As shown, the pulley assembly 3 includes a rail bracket 31, a load-bearing wheel assembly 32, an annular groove 33, a positioning bar 34, and a protrusion 36. The positioning bar 34 is arranged on the inner side of the rail bracket 31. A positioning pin 35 is connected to the middle of the positioning bar 34. The positioning pin 35 is inserted into the annular groove 33. The annular groove 33 is arranged on the rail bracket 31. The protrusion 36 is fixedly connected to the inner side of the positioning bar 34. An adjustment block 37 is clamped in the protrusion 36. The load-bearing wheel assembly 32 is respectively mounted on both ends of the positioning bar 34. This solves the problem of the door body not easily falling, and also allows the height of the load-bearing wheel assembly 32 to be adjusted, realizing the height and angle adjustment of the door body.
[0033] like Figure 1-5 As shown, the load-bearing wheel group 32 is provided with at least two load-bearing wheels, the number of which is determined by the width of the sliding groove of the door frame profile 1, and a connecting rod is provided between the load-bearing wheels. The load-bearing wheels are connected by the connecting rod, thereby improving the stability of the sliding door.
[0034] like Figure 1-5 As shown, two sets of limit plates are provided on both sides of the guide groove 12, and the side limit plates are shorter than the other set of limit plates, thereby preventing the limit plates from contacting and scraping the ground positioning plates 21.
[0035] like Figure 1-5 As shown, the bottom of the positioning plate 21 is fixed to the ground by strong posts or screws. By the positioning plate 21 being firmly installed on the ground, the stable movement of the sliding door can be achieved.
[0036] Example 2
[0037] like Figure 6-9As shown, this embodiment differs from Example 1 in that the door frame profiles 1 are provided in three groups. Connectors 4 are connected to the door frame profiles 1, which are screwed to the outside or inside of the door frame profiles 1. The connectors 4 are provided with second adjustment holes 42 and rollers 43. The second adjustment holes 42 are located on the longitudinal block surface of the connector 4. The rollers 43 are provided on the underside of the connecting block 4 and are rotatably connected within the guide grooves 12. This solves the problem of shaking and allows for smooth movement between the movable sash profiles 1. The bottom rollers 43 extend into the guide grooves 12 within the second group of door frame profiles 1, thereby enabling movement of the three groups of sliding doors.
[0038] Working principle: Install the pulley group 3 in the limit block 11 of the door frame profile 1, and the guide part 2 can be attached to the ground by screws and strong glue. The guide grooves 12 of the two groups of door frame profiles 1 are close to the guide part 2. The guide part 2 is equipped with a positioning plate 21 and a guide wheel 22. The guide wheel 22 rolls in the guide groove 12, thereby realizing the sliding of two groups of sliding doors. When three groups of sliding doors are needed, install the connecting part 4 on one group of door frame profiles 1. The setting of the second adjustment hole 42 and the roller 43 can fix the pulley group 3 and the door frame profile 1, and extend to the guide groove 12 in the second group of door frame profiles 1 through the bottom roller 43, thereby realizing the movement of three groups of sliding doors.
[0039] In the present invention, unless otherwise clearly stipulated and limited, the terms "install", "set", "connect", "fix", "screw" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.
[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
