Description

Technical Field

[0001] This utility model relates to the field of automatic doors, and in particular to an automatic door installation and lifting mechanism. Background Technology

[0002] The lifting mechanism of an automatic door refers to a mechanical device that drives the door leaf to move vertically along the guide rail through a motor and transmission system. It typically includes components such as pulleys, counterweights, and limit switches to achieve smooth lifting and lowering. It is suitable for automatic door scenarios that require vertical opening and closing, such as industrial warehouses, garages, and clean rooms.

[0003] Existing automatic door lifting mechanisms require additional drive components such as motors or cylinders for their lubricating oil spraying structure. The spraying structure cannot be linked to the lifting structure of the automatic door itself, resulting in high installation costs.

[0004] Therefore, the existing automatic door lifting mechanism's lubricating oil spraying system relies on an additional drive device and cannot be linked with the door lifting structure, resulting in high installation costs. There is an urgent need to design a new type of automatic door installation lifting mechanism. Utility Model Content

[0005] In order to overcome the problem that the existing automatic door lifting mechanism's lubricating oil spraying system requires an additional drive device and cannot be linked with the door lifting structure, resulting in high installation costs.

[0006] The technical solution of this utility model is as follows: an automatic door installation and lifting mechanism, including an installation frame; it also includes a fixing plate, a press-type sprayer, a nozzle, and a cam. Two symmetrical connecting seats are installed on the front surface of the installation frame, and a drive shaft is rotatably connected between the two connecting seats. Guide rails are provided on both the left and right sides of the bottom surface of the installation frame, and connecting components are provided on the opposite surfaces of the two guide rails. A lifting door body is connected between the two connecting components. A fixing plate is provided at the lower position of the opposite surface of the two connecting seats. A press-type sprayer is provided at the front position of the upper surface of the two fixing plates. A nozzle is connected to the bottom surface of the press-type sprayer and passes through the fixing plate. A cam is provided on the outer surface of the drive shaft corresponding to the positions of the two press-type sprayers.

[0007] Preferably, by setting a drive shaft, the drive shaft can drive the cam to rotate synchronously when rotating. With each rotation, the cam's protruding position will squeeze the button of the press-type spray bottle, so that the lubricating oil inside the press-type spray bottle can be sprayed onto the contact surface between the guide rail and the slider through the nozzle. Thus, the rotation of the drive shaft itself can achieve the spraying of lubricating oil, thereby lubricating the guide rail. This solves the problem that the existing automatic door installation and lifting mechanism requires an additional motor or cylinder or other drive component for the lubricating oil spraying structure, and cannot be linked with the automatic door's own lifting structure to the spraying structure, resulting in high installation costs.

[0008] Preferably, the connecting assembly includes a slider, a connecting plate, and fixing bolts; sliders are slidably connected to the opposite surfaces of the two guide rails, a connecting plate is installed on the side surface of the slider away from the corresponding guide rail, and two symmetrical fixing bolts are connected to the rear surface of the connecting plate, and the lifting door body is fixed to the connecting plate by the fixing bolts.

[0009] Preferably, a drive wheel is installed on the outer surface of the drive shaft at the side position of both connecting seats. One end of a belt is connected to the outer surface of the drive wheel, and the other end of the belt is connected to the rear surface of the slider.

[0010] Preferably, a speed reducer is mounted on the front surface of the mounting frame, located on the left side of the drive shaft. The output end of the speed reducer is connected to the left end of the drive shaft, and a drive motor is mounted on the front surface of the speed reducer.

[0011] Preferably, a controller is installed on the left side of the front surface of the mounting frame, a limit seat is installed at the bottom side of the left guide rail, a trigger button is installed on the upper surface of the limit seat, and the controller is electrically connected to the trigger button.

[0012] Preferably, the bottom surfaces of the two guide rails are connected to a collection chamber, and the upper surface of the collection chamber is provided with an oil leakage groove corresponding to the position of the two guide rails.

[0013] Preferably, both connectors are fixed to the mounting frame by welding.

[0014] The beneficial effects of this utility model are:

[0015] 1. By setting a drive shaft, the drive shaft can drive the cam on its outer surface to rotate. When rotating, the cam's protruding position will continuously press the button of the press-type spray bottle. When the press-type spray bottle is pressed, the lubricating oil inside can be sprayed through the nozzle onto the contact surface between the guide rail and the slider. Thus, the rotation of the drive shaft itself can achieve the spraying of lubricating oil, thereby lubricating the guide rail. This solves the problem that the existing automatic door installation and lifting mechanism requires an additional motor or cylinder or other drive component for the lubricating oil spraying structure, and cannot be linked with the automatic door's own lifting structure, resulting in high installation costs.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-4This utility model provides an embodiment of an automatic door installation and lifting mechanism, including an installation frame 1; it also includes a fixing plate 7, a press-type spray bottle 8, a nozzle 9, and a cam 10. Two symmetrical connecting seats 2 are mounted on the front surface of the installation frame 1, and a drive shaft 3 is rotatably connected between the two connecting seats 2. Guide rails 4 are provided on both the left and right sides of the bottom surface of the installation frame 1, and connecting components are provided on the opposite surfaces of the two guide rails 4. A lifting door body 6 is connected between the two connecting components. Fixing plates 7 are provided at the lower position on the opposite surfaces of the two connecting seats 2, and a cam 10 is provided at the front position on the upper surface of the two fixing plates 7. The press-type spray bottle 8 has a nozzle 9 connected to its bottom surface. The nozzle 9 passes through the fixed plate 7. The outer surface of the drive shaft 3 is provided with cams 10 corresponding to the positions of the two press-type spray bottles 8. By setting the drive shaft 3, when the drive shaft 3 rotates, it can drive the cams 10 to rotate synchronously. Each rotation of the cam 10 will cause the protruding position of the press-type spray bottle 8 to squeeze the button, so that the lubricating oil inside the press-type spray bottle 8 can be sprayed onto the contact surface between the guide rail 4 and the slider 51 through the nozzle 9. Thus, the rotation of the drive shaft 3 itself can achieve the spraying of lubricating oil, thereby lubricating the guide rail 4.

[0023] Please see Figures 1-4 In this embodiment, the connecting assembly includes a slider 51, a connecting plate 52, and fixing bolts 53. Slider 51s are slidably connected to the opposing surfaces of the two guide rails 4. A connecting plate 52 is mounted on the side surface of the slider 51 away from the corresponding guide rail 4. Two symmetrical fixing bolts 53 are connected to the rear surface of the connecting plate 52. The lifting door body 6 is fixed to the connecting plate 52 by the fixing bolts 53. By setting the fixing bolts 53, it is easy to fix the lifting door body 6 to the connecting plate 52, improving installation convenience. Drive wheels 11 are mounted on the outer surface of the drive shaft 3 at the side positions of the two connecting seats 2. Leather belts are connected to the outer surface of the drive wheels 11. One end of the belt 12 and the other end of the belt 12 are connected to the rear surface of the slider 51. By setting the transmission wheel 11, the transmission shaft 3 can drive the transmission wheel 11 to rotate synchronously when rotating, thereby winding or unwinding the belt 12, thereby pulling the lifting door body 6 to lift. The front surface of the mounting frame 1 is equipped with a reducer 13 located on the left side of the transmission shaft 3. The output end of the reducer 13 is connected to the left end of the transmission shaft 3. The front surface of the reducer 13 is equipped with a drive motor 14. By setting the drive motor 14, the transmission at its output end is transmitted to the transmission shaft 3 through the reducer 13 during operation, which can increase the rotational stability of the transmission shaft 3.

[0024] Please see Figures 1-4In this embodiment, a controller 15 is installed on the left side of the front surface of the mounting frame 1, and a limit seat 16 is installed at the bottom side of the left guide rail 4. A trigger button 17 is installed on the upper surface of the limit seat 16. The controller 15 is electrically connected to the trigger button 17. By setting the limit seat 16 and the trigger button 17, when the lifting door body 6 descends to be in contact with the trigger button 17, a signal can be sent to the controller 15 to shut down the drive motor 14. The bottom surfaces of the two guide rails 4 are connected to the collection chambers 18. The upper surface of the collection chambers 18 is provided with oil leakage grooves 19 corresponding to the positions of the two guide rails 4. By setting the collection chambers 18 and the oil leakage grooves 19, excess lubricating oil flowing down from the surface of the guide rails 4 can flow into the interior of the collection chambers 18 through the oil leakage grooves 19 for recycling. The two connecting seats 2 are fixed to the mounting frame 1 by welding. By using welding to fix the mounting frame 1 and the connecting seats 2, the fixing strength can be improved and the structure can be prevented from loosening.

[0025] During operation, the fixing bolts 53 facilitate the fixation between the lifting gate body 6 and the connecting plate 52, improving installation convenience. The transmission wheel 11, when the transmission shaft 3 rotates, drives the transmission wheel 11 to rotate synchronously, thereby winding or unwinding the belt 12 to pull the lifting gate body 6 up and down. The drive motor 14, when in operation, transmits its output transmission to the transmission shaft 3 through the reducer 13, increasing the rotational stability of the transmission shaft 3. The limit seat 16 and trigger button 17, when the lifting gate body 6 descends to be in contact with the trigger button 17, can send a signal to the controller 15 to shut off the drive motor 14. The collection chamber 18 and oil leakage trough 19 allow excess lubricating oil flowing from the surface of the guide rail 4 to flow into the collection chamber 18 through the oil leakage trough 19 for recycling. The mounting frame 1 and connecting seat 2 are fixed by welding, improving the fixing strength and preventing the structure from loosening.

[0026] Through the above steps, by setting the transmission shaft 3, the transmission shaft 3 can drive the cam 10 on its outer surface to rotate. When rotating, the protruding position of the cam 10 will continuously press the button of the press-type spray bottle 8. When the press-type spray bottle 8 is pressed, the lubricating oil inside can be sprayed onto the contact surface between the guide rail 4 and the slider 51 through the nozzle 9. Thus, the lubricating oil can be sprayed through the rotation of the transmission shaft 3 itself, thereby lubricating the guide rail 4. This solves the problem that the existing automatic door installation and lifting mechanism requires an additional motor or cylinder drive component for the lubricating oil spraying structure, and cannot be linked with the automatic door's own lifting structure to spray the structure, resulting in high installation costs.
