Description

Technical Field

[0001] The utility model relates to the technical field of glass doors, in particular to an independently movable and linked glass door. Background Art

[0002] A sliding door is a door structure that relies on a guide rail to achieve sliding connection with the door. In existing sliding door structures, the bottom guide rail is generally a U-shaped frame structure, and multiple guide rails are provided in the U-shaped frame structure to limit the door. The bottom guide rail of this U-shaped structure is prone to water and dust accumulation, which is difficult to clean. Once the amount of dust is large, the sliding door will be stuck and not slide smoothly, affecting the use of the sliding door. Utility Model Content

[0024] The utility model is further described below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 9 As shown, the utility model discloses an independent mutually movable and linked glass door, which comprises a door frame assembly; a sliding door is arranged in the door frame assembly; an upper guide rail 8 and a lower guide rail 5 are arranged on the upper and lower sides of the door frame assembly respectively; an upper guide rail groove 801 with an opening facing upward is arranged on the inner side surface of the upper guide rail 8; the number of the sliding doors is three; the three sliding doors are respectively a first side sliding door 2, a middle sliding door 6 and a second side sliding door 14; an upper roller bracket 11 is fixed to the top of the first side sliding door 2 and the middle sliding door 6; an upper roller 10 is rotatably connected to the upper roller bracket 11; the upper roller 10 is rollingly connected to the upper guide rail groove 801; the first side A lower roller bracket 13 is fixed to the bottom of the sliding door 2 and the middle sliding door 6; a limiting wheel 4 is fixed on the lower roller bracket 13; a guide rail groove 501 with an opening facing downward is provided on the lower guide rail 5; the width of the guide rail groove 501 is equal to the diameter of the limiting wheel 4; the limiting wheel 4 is embedded in the guide rail groove 501; a grooved roller 12 is provided at the bottom of the second side sliding door 14; a lower supporting guide rail 502 is fixed to the top of the lower guide rail 5; the cross section of the lower supporting guide rail 502 is in an arc shape; the grooved roller 12 is slidably connected to the lower supporting guide rail 502; the inner top wall of the door frame assembly is provided with a sliding groove slidably connected to the second side sliding door 14;

[0026] The width of the sliding groove is slightly smaller than the thickness of the second side sliding door 14, ensuring that the second side sliding door 14 can still slide smoothly after being inserted into the sliding groove; the grooved roller 12 is essentially the same as the prior art, so it is not described in detail;

[0027] The first side sliding door 2 and the middle sliding door 6 are both buckled on the upper guide groove 801 through the upper roller 10 to form a hanging structure, and a rolling connection is formed between the upper roller 10 and the upper guide groove 801, and the entire sliding door is supported by the upper guide groove 801; in addition, after the limiting wheel 4 is embedded in the guide groove 501, the bottom of the sliding door can slide along the guide groove 501 in a directional manner, so that the bottom of the sliding door will not shake; a notch is opened on the side surface of the lower guide rail 5, so that the limiting wheel 4 is inserted into the guide groove 501 after passing through the notch;

[0028] The second side sliding door 14 is guided by the sliding groove provided at the bottom of the upper wall material 9, and the grooved roller 12 is in rolling connection with the lower support rail 502, so that the second side sliding door 14 can slide independently in the door frame assembly;

[0029] In this structure, the guide groove structure of the lower guide rail of the glass door opens downward to prevent dust or water from accumulating at the sliding position of the sliding door, making the sliding door slide more smoothly.

[0030] As a preferred embodiment of the present invention, a magnet strip 7 is fixed on the side surface of the door frame assembly; a magnetic strip that can be adsorbed and fixed by the magnet strip (7) is fixed on the side surfaces of the first side sliding door 2 and the second side sliding door 14;

[0031] The magnetic strip is made of magnetic material and has no essential difference from the prior art, so it is not described in detail here; the first side sliding door 2 is fixed on the door frame assembly through the adsorption of the magnet bar 7 to the magnetic strip to prevent the sliding door from opening automatically; when the first side sliding door 2 needs to be opened, the adsorption force of the magnet bar 7 on the magnetic strip needs to be overcome.

[0032] As a preferred embodiment of the utility model, a sealing strip 3 is fixed on the door frame assembly; the magnet strip 7 is fixed inside the sealing strip 3; in addition to being used to prevent wind, water and dust from entering the door gap, the sealing strip 3 also utilizes the elasticity of the sealing strip 3 to buffer the impact of the sliding door on the magnet strip 7, thereby reducing the risk of the magnet strip 7 being smashed by the sliding door.

[0033] As a preferred embodiment of the present invention, the lower roller brackets 13 are all arranged on the same horizontal plane;

[0034] The two ends of the bottom of each sliding door are fixed with lower roller brackets 13; and the lower roller bracket 13 of the front door is arranged between the two lower roller brackets 13 of the rear sliding door;

[0035] When one of the sliding doors is pulled, the lower roller bracket 13 of the sliding door can be pulled to move together with the lower roller bracket 13 of the adjacent sliding door, and after pulling the last door, the remaining doors can be driven to move together, thereby achieving a linkage effect.

[0036] The above description is only a preferred embodiment of the present utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the present utility model patent application are included in the scope of the present utility model patent application.
