Description

Technical Field

[0001] The utility model relates to the technical field of telescopic doors, in particular to an electric telescopic door. Background Art

[0002] Electric telescopic doors are also called electric doors. They are mainly composed of telescopic door bodies, machine heads, and controllers. The track modes are divided into single-track and trackless. The door bodies are generally made of high-quality aluminum alloy and ordinary square tubes. Electric telescopic doors are widely used in institutions, colleges, entertainment venues, hotels, various industrial and mining plants, workshops, warehouses, machine rooms, garages and other places, or can be used as movable fences. Most electric telescopic doors on the market today have very good performance, but compared to the night, the lack of light makes it easy for people to ignore its existence, or in windy weather, because electric telescopic doors have no fasteners, leading to some unnecessary dangerous problems.

[0003] In this regard, the utility model patent with announcement number CN218235005U proposes an electric telescopic door, which is equipped with warning lights and monitors. During night, the warning lights on the front and top of the pushing frame 2 are lit, and the lighting lights on the front of the control box are turned on to assist the monitor in monitoring the scene in front of the electric telescopic door. If any abnormality is found, the alarm and prompt can be issued by the alarm light and horn. At the same time, a ratchet, a rack and a cylinder are set. When closing the door, the staff turns on the controller, the cylinder starts, and the cylinder output shaft moves downward, driving the scissor frame connected to it to move up and down. After being restricted by the slide groove, the support rod is driven to slide inside the slide groove, driving the scissor frame above to be pushed together, thereby pushing the pushing frame horizontally to the left to push the rack into the control box, and starting the motor. The ratchet fixes the rack to fix the pushing frame.

[0004] In the above scheme, when the rack enters the control box, if the motor or cylinder is powered off or damaged, the ratchet wheel cannot rotate, making it difficult for the rack engaged with the ratchet wheel to move out of the control box, and the push frame is difficult to retract to the side of the protection box, which in turn makes it impossible for vehicles and pedestrians to pass through the electric telescopic door. It is necessary to wait for maintenance personnel to repair it, which can easily cause inconvenience to personnel travel and is time-consuming and laborious. In addition, if too much force is used to retract the push frame by human power, the thrust formed may cause damage to the bottom of the cylinder when the cylinder piston moves to the bottom.

[0005] In view of this situation, the purpose of the utility model is to provide an electric telescopic door, which is provided with a button and a card block. The staff presses the button, the card block enters the inside of the rotating shaft, and then pushes the gear to the bearing and releases the button, and the gear plate can enter and exit the operating box at will.

The button 16 is fixedly connected to the bottom of the card block 17. The top of the button 16 is slidably inserted on the side of the first gear 21 close to the rotating shaft 12. A limit plate 18 is installed on the side of the first gear 21 close to the button 16. The limit plate 18 is used to prevent the staff from using too much force when moving the first gear 21 to the card block 17 so that the first gear 21 is not stuck on the card block 17. The limit plate 18 is fixedly installed on the rotating shaft 12. A bearing 11 is fixedly installed on the side of the rotating shaft 12 close to the first gear 21. The bearing 11 is used to limit the moving range of the first gear 21 when the first gear 21 is out of the card block 17. A tooth plate 14 is installed at the bottom of the first gear 21, and the tooth plate 14 is installed through one side of the operation box 1.

[0026] Specifically, a plurality of evenly distributed springs 19 and a first limiting column 20 are fixedly installed at the bottom of the button 16 and the block 17, the other end of the spring 19 is fixedly installed on the fixed column 15, and the other end of the first limiting column 20 is slidably inserted into the fixed column 15. The spring 19 is used for resetting the button 16 and the block 17, and the first limiting column 20 is used for limiting the moving direction of the button 16 and the block 17.

[0027] In this embodiment, when the motor 10 stops working and the toothed plate 14 stays in the operating box 1, the staff opens the maintenance door 4 on the operating box 1 and presses the button 16. The spring 19 is compressed, the first limiting column 20 enters the fixing column 15, and the block 17 enters the rotating shaft 12 from the inside of the first gear 21. Then the staff pushes the first gear 21 toward the bearing 11 and releases the button 16. The button 16, the block 17 and the first limiting column 20 are reset under the elastic force of the spring 19. At this time, the first gear 21 is between the bearing 11 and the block 17. When the toothed plate 14 enters the operating box 1, the staff pushes the first gear 21 toward the limiting plate 18. Figure 5As shown, since the top of the block 17 is a triangle, the first gear 21 moves along the inclined surface from the bottom of the triangle to the top, and squeezes the block 17 into the rotating shaft 12 until the first gear 21 contacts the limit plate 18, and the block 17 is reset and enters the first gear 21. At this time, the first gear 21 is meshed with the tooth plate 14.

[0028] Specifically, a fence 2 is fixedly installed on the side of the tooth plate 14 away from the operating box 1, and a plurality of evenly distributed first slide grooves 7 are opened on one side of the fence 2. Four brackets 6 are slidably installed inside the first slide grooves 7, and two scissor racks 5 are rotatably installed on one side of the bracket 6. The sliding of the bracket 6 in the first slide groove 7 can control the opening and closing of the scissor rack 5, and then control the switch of the fence 2.

[0029] Specifically, a control box 3 is fixedly installed on the side of the fence 2 away from the tooth plate 14, and a second slide groove 9 is penetrated and opened on the side of the control box 3 close to the fence 2. A slide bar 8 is slidably installed inside the second slide groove 9, and the up and down movement of the slide bar 8 is used to control the movement of the bracket 6. The slide bar 8 is fixedly installed on the side of the bracket 6 close to the control box 3. A rack 24 is fixedly installed inside the control box 3, and second gears 22 are symmetrically installed on both sides of the rack 24. One of the second gears 22 is close to the second slide groove 9 and is rotatably installed on the slide bar 8. A third gear 23 is fixedly installed on the side of the second gear 22 away from the second slide groove 9, and a handle 29 is fixedly installed on the side of the third gear 23 close to the second slide groove 9 away from the second gear 22. When the motor 2 8 cannot work, the staff controls the upward and downward movement of the second gear 22 by turning the handle 29, and then controls the opening and closing of the fence 2. A slide plate 27 is installed on the side of the other third gear 23 away from the second gear 22. The slide plate 27 is used to fix the motor 28. The motor 28 is fixedly installed on the side of the slide plate 27 away from the third gear 23. The output end of the motor 28 passes through the slide plate 27 and is fixedly connected to the third gear 23. Second fixed plates 25 are symmetrically installed inside the control box 3. The second fixed plates 25 are used to control the moving distance of the slide plate 27. Second limiting columns 26 are symmetrically installed between the second fixed plates 25. The slide plate 27 is slidably installed on the second limiting columns 26. The second limiting columns 26 are used to control the moving direction of the slide plate 27.

[0030] Specifically, the first gear 21 is meshed with the toothed plate 14 , and when the toothed plate 14 is meshed with the first gear 21 , the fence 2 can be fixed, thereby reducing the probability of the fence 2 running off track.

[0031] Specifically, the two second gears 22 are meshed with the rack 24 , the diameters and the numbers of teeth of the two second gears 22 are equal, and the distances of the two second gears 22 when moving are equal.

[0032] Specifically, the two third gears 23 mesh with each other, and the diameters and numbers of teeth of the two third gears 23 are equal, thereby ensuring that the two second gears 22 move at the same time and at the same speed.

[0033] Specifically, a maintenance door 4 is hinged on one side of the control box 3 and the operation box 1. The maintenance door 4 is provided to facilitate manual adjustment by staff and maintenance by maintenance personnel when the motor 10 and the motor 28 are damaged.

[0034] In this embodiment, when the motor 28 works normally, when opening the door, the staff starts the motor 28, the second gear 22 and the third gear 23 rotate, and because the second gear 22 is meshed with the rack 24, the second gear 22 moves downward along the rack 24, and the slide bar 8 moves downward along the second slide slot 9, thereby driving the bracket 6 to move downward along the first slide slot 7, and the two brackets 6 approach each other, thereby causing the scissor frame 5 to open, thereby pushing the fence 2 to move toward the operating box 1 until the tooth plate 14 completely enters the operating box 1, and the motor 28 stops working. When closing the door, the staff reverses the motor 28, the second gear 22 moves downward, the slide bar 8 and the bracket 6 move downward, the scissor frame 5 resets, and the fence 2 moves to the right until it resets, and the motor 28 stops working after resetting.

[0035] When the motor 28 fails to work, the staff opens the maintenance door 4 on the control box 3 and holds the handle 29 . The staff controls the upward and downward movement of the second gear 22 by turning the handle 29 , thereby controlling the opening and closing of the fence 2 .

[0036] How it works:

[0037] When the motor 10 stops working and the toothed plate 14 stays in the operating box 1, the staff opens the maintenance door 4 on the operating box 1 and presses the button 16. The spring 19 is compressed, the first limiting column 20 enters the fixing column 15, and the block 17 enters the rotating shaft 12 from the inside of the first gear 21. Then the staff pushes the first gear 21 toward the bearing 11 and releases the button 16. The button 16, the block 17 and the first limiting column 20 are reset under the elastic force of the spring 19. At this time, the first gear 21 is between the bearing 11 and the block 17. When the toothed plate 14 enters the operating box 1, the staff pushes the first gear 21 toward the limiting plate 18. Figure 5 As shown, since the top of the block 17 is a triangle, the first gear 21 moves along the inclined surface from the bottom of the triangle to the top, and squeezes the block 17 into the rotating shaft 12 until the first gear 21 contacts the limit plate 18, and the block 17 is reset and enters the first gear 21. At this time, the first gear 21 is meshed with the tooth plate 14.

[0038] When the motor 28 works normally, when opening the door, the staff starts the motor 28, the second gear 22 and the third gear 23 rotate, and because the second gear 22 is meshed with the rack 24, the second gear 22 moves downward along the rack 24, and the slide bar 8 moves downward along the second slide slot 9, thereby driving the bracket 6 to move downward along the first slide slot 7, and the two brackets 6 approach each other, causing the scissor frame 5 to open, thereby pushing the fence 2 to move toward the operating box 1 until the tooth plate 14 completely enters the operating box 1, and the motor 28 stops working. When closing the door, the staff reverses the motor 28, the second gear 22 moves downward, the slide bar 8 and the bracket 6 move downward, the scissor frame 5 resets, and the fence 2 moves to the right until it resets, and the motor 28 stops working after resetting.

[0039] When the motor 28 fails to work, the staff opens the maintenance door 4 on the control box 3 and holds the handle 29 . The staff controls the upward and downward movement of the second gear 22 by turning the handle 29 , thereby controlling the opening and closing of the fence 2 .

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
