Detailed Description

Referring to fig. 1 to 4, the present embodiment provides an electric lower rail-less moving door, which includes a driving assembly 1, an upper rail 2, a moving door body 3, door posts 4, and a cross member 5. The movable door body 3 is rectangular in shape and two in number.

The two door posts 4 are symmetrically arranged on two sides of the door opening 6, and the cross beam 5 is welded and fixed at the upper ends of the two door posts 4. In particular, the cross beam 5 is a rectangular frame, and a cross bar 41 is welded horizontally at the lower position of the frame, and the cross bar 41 is used for installing functional components.

The driving assembly 1 comprises a motor 11, a driving wheel 12, a driven wheel 13, a transmission belt 14 and two linkage frames 15, and the upper rail 2 is mounted on the cross rod 41 through screws. Four sliding blocks capable of sliding freely on the upper rail 2 are arranged on the upper rail 2, the four sliding blocks are divided into two groups, the two sliding blocks are installed corresponding to the two linkage frames 15 through screws, and the two linkage frames 15 are movably arranged on the upper rail 2 through the sliding blocks. In particular, the method comprises the steps of,

the linkage frame 15 comprises angle irons and a frame body, wherein the sliding blocks are fixed on the inner side of the vertical wall of the angle irons through screws, and the frame body is fixed on the bottom surface of the horizontal wall of the angle irons.

The two movable door bodies 3 can be fixedly arranged on the frame body by welding or screws. Because the weight of the movable door body 3 is borne by the frame body, a reinforcing plate can be arranged on the frame body, so that the structural strength is effectively enhanced.

The two movable door bodies 3 are respectively arranged on the corresponding linkage frames 15, the motor 11 is arranged at one end of the cross bar 41 through the machine base, the driven wheel 13 is arranged at the other end of the cross bar 41 through the wheel frame, the driving wheel 12 is arranged on the driving shaft of the motor 11, the driving belt 14 is wound on the driving wheel 12 and the driven wheel 13, an upper straight part and a lower straight part are formed on the driving belt 14, one linkage frame 15 is connected with the upper straight part, and the other linkage frame 15 is connected with the lower straight part. Preferably, a supporting wheel 15 capable of supporting the driving belt 14 is arranged on the cross beam 5 corresponding to the middle position of the driving wheel 12 and the driven wheel 13, so that the sagging amplitude of the driving belt 14 is reduced, and the running stability is improved. When the driving belt 14 runs, the two movable door bodies 3 can be correspondingly driven to relatively close or open by the two linkage frames 15.

Preferably, the roller bearings 7 may be disposed on the ground 9 corresponding to the moving track of the moving door 3, specifically, long strips 8 are mounted on two sides of the doorway 6, that is, on the outer sides of the door post 4, by screws, and the long edges of the long strips 8 run in line with the moving track of the moving door 3, and just conceal the shadows of the lower edge of the moving door 3, so as to ensure the aesthetic property. The two ends of the long strip plate 8 are vertically provided with rollers, and the roller bearings 7 are arranged on the rollers. Correspondingly, a channel steel 31 matched with the roller bearing 7 is arranged on the bottom surface of the movable door body 3. The roller bearing 7 can slide in the channel steel 31, and the stability of the movement of the movable door body 3 can be further improved by guiding the roller bearing 7. In addition, if the moving range of the moving door body 3 is to be increased, the length of the channel steel 31 may be lengthened. Namely, the tail end of the channel steel 31 extends out of the moving door body 3 for a certain distance to form an extension part 32, so as to enlarge the moving range of the moving door body 3.

When the door is used, a thermal infrared human body sensor can be arranged at the position of the door opening 6 for convenient use, when the thermal infrared human body sensor senses that a person comes, a door opening signal is automatically fed back to the controller, the controller controls the motor 11 to drive the driving belt 14 to operate, and the driving belt 14 correspondingly drives the two movable door bodies 3 to open relatively through the two linkage frames 15. When no person is sensed through the back of the gate 6 or the thermal infrared human body sensor, the controller controls the motor 11 to reversely drive the driving belt 14 to operate so as to drive the two movable gate bodies 3 to relatively perform closing motion. Or a push button switch is directly installed, and the push button switch is manually pressed to control the opening and closing actions of the two movable door bodies 3. Because the two movable door bodies 3 are hung on the upper rail 2 through the linkage frame 15, the traditional lower rail component is omitted, dirt is not easy to collect, sanitation is easy to clean, the ground flatness of the door opening 6 is further ensured, and the overall attractiveness of the door is good.
