Technical Field

[0001] The utility model relates to the field of sliding doors, in particular to an underground automatic door. Background Art

[0002] Theoretically, automatic sliding doors should be understood as an extension of the concept of automatic doors, which are developed and improved according to human needs. Automatic doors refer to control units that can recognize the action of a person approaching the door (or some kind of entry authorization) as a door opening signal, open the door through a drive system, and automatically close the door after the person leaves, and control the opening and closing process.

[0003] When assembling traditional embedded automatic doors, the embedded chassis is usually installed in the embedded space on the ground after it is produced in the factory. However, during the installation of the embedded chassis, it is necessary to ensure the flatness of the embedded chassis and conduct multiple debugging. Since the embedded chassis is relatively bulky, the assembly process of the embedded chassis is very inconvenient, which affects the assembly efficiency and needs to be improved.

[0030] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0031] like Figure 1 , Figure 2 As shown, an underground automatic door includes a chemical anchor bolt 1, a support seat 2, an adjustment plate 3, a press-fit nut 4, an embedded chassis 5, a driving mechanism 6, a sliding plate 7, a movable door leaf 8 and a fixed door leaf 9.

[0032] like Figure 1 , Figure 2 As shown, the chemical anchor 1 is vertically embedded and fixed in the embedded space on the ground, the support seat 2 is sleeved on the upper end of the chemical anchor 1, and the adjustment disk 3 is threadedly connected to the upper end of the chemical anchor 1 and is used to support the support seat 2 and realize the adjustment of the height position of the support seat 2.

[0033] like Figure 1 , Figure 2As shown, the press-fit nut 4 is threadedly connected to the upper end of the chemical anchor 1 and is used to compress the support base 2. The embedded chassis 5 is made of stainless steel sealing material and is fixed to the support base 2 by bolts. A drainage pipe 51 is provided at the lower end of the embedded chassis 5. The other end of the drainage pipe 51 is bent and extended to the outside of the ground to achieve timely drainage of internal water.

[0034] like Figure 1 , Figure 2 As shown, an upper end of one side of the embedded chassis 5 is provided with an elongated mounting hole 52 in an open shape, a driving mechanism 6 is provided inside the embedded chassis 5, a sliding plate 7 is connected to the driving mechanism 6, and vertically passes through the mounting hole 52, and the driving mechanism 6 is used to control the sliding plate 7 to slide stably along the length direction of the mounting hole 52. A triangular stabilizing frame is provided inside the embedded chassis 5 to increase the structural strength and stability of the top of the embedded chassis 5.

[0035] like Figure 1 , Figure 2 As shown, the movable door leaf 8 is located on the ground, and the lower end is connected to the sliding plate 7. The fixed door leaf 9 is located on the ground, and is located behind the movable door leaf 8, and extends into the mounting hole 52, and is fixed to the inner side of the embedded chassis 5.

[0036] When assembling, the support seat 2 is sleeved on the upper end of the chemical anchor 1, and the adjustment disk 3 supports the support seat 2, then the levelness of the support seat 2 is measured, and the adjustment disk 3 is rotated to adjust the levelness of the support seat 2. When the support seat 2 meets the levelness requirement, the embedded chassis 5 is directly embedded in the embedded space on the ground, and the embedded chassis 5 is fixed to the support seat 2 with bolts to achieve assembly.

[0037] Therefore, by providing an independently arranged and height-adjustable support base 2, convenient installation and easy adjustment of the horizontality of the support base 2 are achieved, so that the embedded chassis 5 can be easily placed and installed without moving or lifting the heavy embedded chassis 5, thereby making the assembly process more convenient and improving assembly efficiency.

[0038] like Figure 1 , Figure 2 As shown, the sliding plate 7 includes a bottom plate 71, a vertical plate 72 and a horizontal plate 73. The bottom plate 71 is connected to the driving mechanism 6 by bolts. The bottom plate 71 has a long strip notch to achieve the adjustment and installation of the bottom plate 71 in the horizontal direction. The vertical plate 72 is vertically arranged on the bottom plate 71 and passes through the installation hole 52. The horizontal plate 73 is horizontally arranged on the upper side wall of the vertical plate 72 away from the fixed door leaf 9, and is connected to the lower end of the movable door leaf 8.

[0039] Therefore, by setting the sliding plate 7 with a unique structure, the mounting hole 52 on the embedded chassis 5 can be set to a narrow strip, thereby reducing the probability of rainwater entering the chassis, thereby preventing the components in the embedded chassis 5 from short-circuiting or burning, and reducing the burden on maintenance workers.

[0040] like Figure 1 , Figure 2 As shown, a detachably mounted cover 53 is provided on the embedded chassis 5, and the cover 53 extends to the bottom of the movable door leaf 8. The cover 53 can be a floor mat, a marble slab or a tile. When installing the heavier cover 53, a suspension needs to be installed above the chassis to achieve stable support of the cover 53.

[0041] like Figure 1 , Figure 2 As shown, sealing brush strips 81 are provided on both sides of the lower end of the movable door leaf 8, and the outer sealing brush strips 81 abut against the surface of the cover 53. Therefore, by providing the sealing brush strips 81, rainwater from the outside is blocked and isolated, preventing rainwater on the ground from entering the embedded chassis 5.

[0042] like Figure 1 , Figure 2 As shown, the driving mechanism 6 includes a slide rail 61, a wheel frame 62, a guide wheel 63, a driving source 64 and a pulley set 65. The slide rail 61 is horizontally arranged on the bottom wall of the embedded chassis 5, the wheel frame 62 is arranged above the slide rail 61, and is connected to the lower end of the sliding plate 7. The position of the connecting sliding plate 7 is fixed by bolts, and the height direction of the connecting position can be adjusted, thereby realizing the height adjustment of the sliding plate 7. The guide wheel 63 is a double wheel set, and is rotatably connected to the wheel frame 62, and is slidably connected to the slide rail 61.

[0043] like Figure 1 , Figure 2 As shown, the driving source 64 is arranged in the embedded chassis 5, and the driving source 64 is a waterproof motor to prevent rainwater from eroding and affecting the driving source 64. The pulley group 65 connects the driving source 64 and the wheel frame 62. When the movable door leaf 8 is heavy, the pulley group 65 can be replaced with a sprocket group.

[0044] When controlling the movable door leaf 8 to slide, the driving source 64 works and controls the pulley set 65 to operate. At this time, the pulley set 65 drives the wheel frame 62 to slide. The wheel frame 62 slides on the slide rail 61 through the guide wheel 63 and drives the sliding plate 7 to move synchronously, thereby realizing the opening and closing control of the movable door leaf 8.

[0045] like Figure 1 , Figure 2As shown, cleaning rods 66 are provided on both the front and rear sides of the wheel frame 62, and the cleaning rods 66 abut against the surface of the slide rail 61, and the two ends are bent downward to abut against the two sides of the slide rail 61. Therefore, by providing the cleaning rods 66, the surface of the slide rail 61 can be automatically cleaned when the movable door leaf 8 moves, ensuring the cleanliness of the surface of the slide rail 61 and preventing jamming or derailment due to foreign matter.
