DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0030] Please refer to Figures 1-6 As shown in the figure, a hidden sliding assembly of sliding door comprises a lower frame 6 laid under the ground and a movable frame 1 laid on the ground, the inside of the lower frame 6 is fixedly connected with a guide rail 5, the top end of the lower frame 6 is assembled with a plurality of top frames 3 flush with the ground, a gap is arranged between the adjacent two top frames 3, the bottom end of the movable frame 1 extends to the inside of the lower frame 6 through the gap and is slidably connected with the guide rail 5 through a pulley 4, and a drainage hole 8 is arranged on the frame body of the lower frame 6.

[0031] By fixing the guide rail 5 in the lower frame 6 buried under the ground and extending the bottom end of the movable frame 1 below the ground to be slidably connected with the guide rail 5 through the pulley 4, the problem that the lower frame 6 is easy to trip is avoided, and by arranging the drainage hole 8, the water entering the inside of the lower frame 6 can be drained, so as to avoid water accumulation in the lower frame 6. The liquid entering the lower frame 6 enters the drainage pipeline through the drainage hole 8.

[0032] A chain plate 7 is arranged at the gap between the two top frames 3, and a supporting groove 31 for limiting and supporting the chain plate 7 is arranged on one side of the adjacent two top frames 3, a plurality of supporting wheels 11 are arranged on the middle part of the bottom end of the movable frame 1 along the length direction thereof, and a pressing wheel 14 is arranged at each end of the movable frame 1, the chain plate 7 penetrates through the movable frame 1 and is slidably connected with the movable frame 1 through the supporting wheels 11, and the pressing wheel 14 is located above the chain plate 7 for limiting the height of the chain plate 7. Preferably, the upper surface of the chain plate 7 is flush with the ground.

[0033] By arranging the chain plate 7 at the gap between the two top frames 3, the sundries are prevented from entering the lower frame 6 and piling up at the guide rail 5 to affect the sliding of the movable frame 1. Meanwhile, the chain plate 7 penetrates the movable frame 1 and is connected with the movable frame 1 through the plurality of supporting wheels 11. During the sliding of the movable frame 1 along the guide rail 5, the chain plate 7 is separated from the supporting groove 31 under the action of the supporting wheel 11, and the pressing wheel 14 at the two ends of the movable frame 1 limits the chain plate 7, so that only the chain plate 7 directly below the movable frame 1 is separated from the supporting groove 31. In order to prevent the chain plate 7 from sliding in the supporting groove 31, the two ends of the chain plate 7 are fixedly connected with the top frame 3.

[0034] In the chain plate 7, a plurality of plates are arranged in a chain shape, and adjacent two plates are hingedly connected.

[0035] In some embodiments, in order to facilitate the assembly of the movable frame 1, the movable frame 1 comprises two symmetrical positioning frames 13, and the two positioning frames 13 are fixedly connected through the plurality of connecting plates 10. The supporting wheel 11 and the pressing wheel 14 are clamped and limited by the two positioning frames 13. By clamping and positioning the supporting wheel 11 and the pressing wheel 14 through the two movable frames 1, the supporting wheel 11 and the pressing wheel 14 can be limited by inserting the two ends of the supporting wheel 11 and the pressing wheel 14 into the corresponding through holes when the lower frame 6 is installed.

[0036] Since the chain plate 7 at the position of the movable frame 1 is lifted by the supporting wheel 11, in order to prevent sundries from entering the lower frame 6 through the gap at this position, the sealing strips 12 are fixedly connected at the two sides of the bottom end of the movable frame 1, which blocks the sundries and improves the sealing effect between the movable frame 1 and the ground.

[0037] In some embodiments, in order to improve the positioning effect of the chain plate 7, the inner side of the supporting groove 31 is fixedly connected with a magnet 32, and the chain plate 7 is made of ferromagnetic material. When the chain plate 7 falls into the supporting groove 31, the magnet 32 attracts the chain plate 7, thereby improving the limiting effect of the chain plate 7.

[0038] In order to prevent the position of the chain plate 7 from deviating and to accurately fall into the supporting groove 31, the bottom end of the chain plate 7 is fixedly connected with a limiting plate 71, and the two ends of the supporting wheel 11 are provided with a limiting wheel groove at the corresponding position. Under the action of the limiting wheel groove, the chain plate 7 is limited by the limiting plate 71 to prevent the position from deviating.

[0039] In some embodiments, in order to improve the aesthetic appearance, the top end of the top frame 3 is provided with a mounting groove for mounting the decorative plate 2. By mounting a wooden plate, a ceramic tile or other decorative material in the mounting groove to match the nearby ground decoration, the overall aesthetic appearance is improved.

[0040] Specifically, the movable frame 1, the top frame 3 and the lower frame 6 are all aluminum profiles, copper-zinc alloy profiles or stainless steel profiles. They have the advantages of light weight and convenient installation. Obviously, those skilled in the art can also use other metal profiles according to actual needs, not limited to the embodiments.

[0041] In order to facilitate processing and assembly, the lower frame 6 is divided into an outer frame 61 and an inner frame 62, the inner frame 62 is located inside the outer frame 61, and the inner side of the outer frame 61 is fixedly connected with a limiting strip 63 for limiting the inner frame 62. The inner frame 62 is limited by the limiting strip 63, so that the outer frame 61 and the inner frame 62 are assembled.

[0042] Working principle: in the process of sliding the movable frame 1, the chain plate 7 located in front of the sliding direction of the movable frame 1 enters the movable frame 1 and is lifted by the carrier wheel 11, so that it is separated from the supporting groove 31, so that the bottom end of the movable frame 1 extends to the part of the lower frame 6 connected with the pulley 4 through the gap between the two top frames 3, the chain plate 7 lifted by the carrier wheel 11 is connected with the movable frame 1 through the carrier wheel 11, the chain plate 7 located behind the sliding direction of the movable frame 1 loses the lifting of the carrier wheel 11 and falls into the supporting groove 31, at the same time, under the action of the pressing wheel 14 at both ends of the movable frame 1, the chain plate 7 can be limited to avoid the chain plate 7 out of the range of the movable frame 1 from separating from the supporting groove 31;

[0043] The sundries are blocked by the chain plate 7, so that they cannot enter the lower frame 6, thereby avoiding the influence of sundries on the sliding of the movable frame 1, and when water enters the inside of the lower frame 6 through the gap of the chain plate 7, the water can be discharged through the drain hole 8, avoiding water accumulation in the lower frame 6.

[0044] Although the embodiments of the present application have been shown and described, those skilled in the art can understand that various changes, modifications, replacements and variations can be made to the embodiments without departing from the principles and spirits of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
