in the following description, directional terms such as front and rear are used for better illustrating the technical solution of the present invention, so as to facilitate understanding, and are not considered to be limitations of the claims.

The nested gate capable of opening and closing in the same direction comprises an outer door 1 and an inner door 2 nested in the outer door 1, wherein the inner door 2 can move relative to the outer door 1, a first gear 4 at the output end of a motor 3 and a speed reducer is meshed with a first rack 7 on the outer door 1, so that the outer door 1 is driven to move, the bottom parts of two ends of the outer door 1 and the inner door 2 are respectively provided with a traveling device 5, the traveling devices are devices for ensuring the inner door 2 and the outer door 1 to move on the ground, a traveling device 5A at the front end of the inner door 2 is positioned outside a traveling device 5C at the front end of the outer door 1, so that the inner door 2 can move conveniently, if the inner door 2 is wholly sleeved in the outer door 1, the traveling device 5C at the front end of the outer door 1 can block the inner door 2 when the inner door moves, a second gear 6 synchronously rotating with the traveling device 5C at the front end of the outer door 1 is arranged on the outer door 1, and the second gear 6 is meshed with a second rack 8 on the, when the traveling device 5C at the front end of the outer door 1 travels, the second gear 6 rotates therewith, and the inner door 2 is driven to move forward.

The diameter of the second gear 6 is larger than that of the first gear 4 or the roller 9 of the traveling device 5C at the front end of the outer door 1, so that the speed of the inner door 2 is not lower than that of the outer door 1 when the inner door 2 moves, that is, the moving speed of the inner door 2 is higher than that of the outer door 1, and the diameter and the number of teeth of the second gear 6 and the first gear 4 are determined according to the width of the door, the length of the inner door 2 and the length of the outer door 1.

The outer door guide device 13 is arranged on two sides of the upper end of the outer door 1, the outer door can be guaranteed to stably move and cannot topple over, the outer door guide device 13 is fixed on the upright post 12, the number of the upright posts 12 is generally two, the upright post 12 is located on two sides of the door, the upright post 12 can also be a wall body according to specific design, the upright post is only a substitute term and plays a role in supporting the outer door guide device 13, as shown in fig. 2, the upright post 12 is divided into an upright post 12A and an upright post 12B, the motor 3 is located at one end of the upright post 12A, the door is not in contact with the upright post 12B in an opening state, the door can be in contact with the upright post 12B only when the door is completely closed, the guide device is also arranged on one side of the upright post 12B, and the guide device. Outer door guider 13 specifically includes fixed bolster 14, is fixed with two pulleys 15 through the bolt on the fixed bolster 14, and two pulleys 15 are located outer 1 top both sides for carry on spacingly to outer door 1, prevent that outer door 1 from inclining.

A plurality of inner door guiding devices 16 are arranged on two sides of the top of the inner door 2, and the inner door guiding devices 16 are positioned on the top of the outer door 1. The inner door guide device 16 comprises an upper pulley 17 and a lower pulley 18, the upper pulley 17 is fixed on the top inner side panel of the outer door 1 through a bolt, and the lower pulley 18 is fixed on a connecting piece 19 between the vertical rods of the outer door 1 through a bolt. The door guide 16 is to limit the inner door 2 so that it does not tilt in a moving or stationary state.

As shown in fig. 3, the traveling device 5 includes a support 11 symmetrically arranged on both sides of the bottom of the door body, a bearing seat is arranged in the support 11, a bearing is arranged in the bearing seat, a transmission shaft 10 is arranged in a hole in the bearing, and the roller 9 and the second gear 6 are both arranged on the transmission shaft 10.

As shown in fig. 4, another

walking device

5A and 5B of the inner door 2 is provided, specifically, a bearing and a bearing seat are arranged inside the roller, and a transmission shaft penetrates through the bearing and is in interference fit with or welded with the bracket.

It should be emphasized that the running gear 5 of this structure is used only with the inner door 2 and the rear end of the outer door 1, and since the second gear 6 is provided on the transmission shaft 10 of the running gear 5C at the front end of the outer door 1, the second gear 6 needs to be synchronized with the transmission shaft 10, so that a bearing is provided in the bracket 11.

The rollers 9 on the inner door 2 and the outer door 1 share a rail.

As shown in fig. 1, only the upright post 12A is shown, and the upright post 12B on the other side of the door is not shown, at this time, the door is in a fully opened state, the inner door 2 is inside the outer door 1, the door body is tightly attached to the enclosing wall, and no extra space is occupied, compared with the existing retractable door, the door of the present invention does not occupy the original width of the door, but is placed along the wall, so that the original width of the door is fully displayed. In addition, the inner and outer double-layer nested structure ensures that the width of the door body is only half of the width of the door.

When the door needs to be closed, the motor 3 moves to drive the outer door 1 to move, the roller 9 of the outer door 1 rotates along with the rotation, the second gear is synchronous with the roller 9, the second gear 6 drives the inner door 2 to move, the diameter of the second gear 6 is larger than that of the roller 9 or the first gear 4, the moving speed of the inner door 2 is larger than that of the outer door 1 under the condition of the same angular speed, when the inner door 2 reaches the upright post 12B, the motor 3 stops rotating to complete the door closing, and the specific method of how the motor 3 stops rotating belongs to the prior art and does not need to be described redundantly again.

As shown in fig. 2, in the state where the lower door is completely closed, when the door needs to be opened, the motor 3 may be rotated in reverse.

The details of the above are not described in detail since they are prior art.
