DETAILED DESCRIPTION
[0025] The present invention is further described in detail below in conjunction with the embodiments:
[0026] Example 1
[0027] like Figure 1-5 As shown, the utility model provides a rolling shutter device for a cowshed with a self-lubricating function, including a rolling shutter device 1, which is suitable for use in a cowshed. Door frame plates 2 are arranged on both sides of the rolling shutter device 1, and positioning holes 3 are opened on the front ends of the inner walls of both sides of the door frame plate 2. Lubricating units are arranged on both sides of the rolling shutter device 1, and a fixing unit is arranged on the front bottom end of the rolling shutter device 1. A buffer unit is arranged inside the bottom end of the door frame plate 2. The lubricating unit includes frame strips 11 arranged on both sides of the rolling shutter device 1, and rotating gears 12 are rotatably installed on the top ends of both sides of the door frame plate 2. The outer surface of the rotating gear 12 is meshed with the teeth behind the frame strips 11. Limiting columns 13 are fixedly connected on both sides of the bottom end of the door frame plate 2, and a sliding sleeve 14 is fixedly connected to the bottom end of the frame strip 11. The sliding sleeve 14 is movably sleeved on the outer surface of the limiting column 13. A clamp 15 is arranged on the other end of the sliding sleeve 14, and a roller 16 is rotatably installed inside the clamp 15, and the roller 16 is rotatably connected to the inner walls of both sides of the door frame plate 2.
[0028] Furthermore, the pull ring on the front bottom end of the rolling shutter device 1 makes it easy to pull the rolling shutter door downward. When the rolling shutter door moves downward, the sliding sleeves 14 on both sides of the frame slats 11 slide on the outer surfaces of the limiting columns 13, which can achieve the limiting effect, so that the rolling shutter door moves downward smoothly without shaking. At the same time, the rolling shutter door gradually moves downward by rotating the gear 12 and engaging with the teeth at the rear of the frame slats 11, and the clamp 15 drives the rollers 16 to roll on the inner walls on both sides of the door frame plate 2, thereby enhancing the smoothness of the downward movement of the rolling shutter door.
[0029] Example 2
[0030] like Figure 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the fixing unit includes a fixing sleeve 17 arranged on both sides of the front bottom end of the rolling curtain device 1, and an electric telescopic rod 18 is arranged inside the groove at the front bottom end of the rolling curtain device 1, and a push-pull plate 19 is fixedly connected to the bottom end of the electric telescopic rod 18, and a rotating plate 110 is rotatably connected to both sides of the front end of the push-pull plate 19, and a positioning rod 111 is movably connected to the other end of the rotating plate 110, and the positioning rod 111 is movably inserted into the inside of the fixing sleeve 17.
[0031] Furthermore, by starting the electric telescopic rod 18, the electric telescopic rod 18 prompts the push-pull plate 19 to move downward, and the push-pull plate 19 is used to change the inclination angle of the rotating plates 110 on both sides thereof. The rotating plates 110 push the positioning rods 111 on both sides outward, so that the other ends thereof abut against the inside of the positioning holes 3 on the inner wall of the door frame plate 2, thereby fixing the rolling door in position.
[0032] Example 3
[0033] like Figure 1-5 As shown, on the basis of Examples 1-2, the utility model provides a technical solution: preferably, the buffer unit includes a buffer plate 23 arranged on the outer surface of the limit column 13, and slide grooves 21 are opened on both sides of the inner bottom end of the door frame plate 2, and sliding rods 22 are fixedly connected to the inner walls of both sides of the slide grooves 21. A rotating shaft 24 is rotatably connected to the middle position of the bottom end of the buffer plate 23, and a buffer support plate 25 is rotatably connected inside the rotating shaft 24. A rotating shaft slider 26 is rotatably connected to the other end of the buffer support plate 25. The rotating shaft slider 26 is slidably sleeved on the outer surface of the sliding rod 22, and the outer surface of the sliding rod 22 is located on the outer side of the rotating shaft slider 26 and is movably sleeved with a return spring 27.
[0034] Furthermore, when the rolling shutter device 1 moves downward instantly, its bottom end will hit the top of the buffer plate 23, and the buffer plate 23 will move downward under the pressure, squeezing the spring bodies on both sides. The rotating shaft 24 at its bottom end will cause the buffer support plate 25 to rotate under the action of pressure, changing the inclination angle, and the other end will drive the rotating shaft slider 26 to slide on the outer surface of the sliding rod 22, squeezing the return spring 27 on the other side, and using the elastic driving force of the return spring 27 to cause the component to return to its original position, thereby achieving buffering, reducing the impact force, and protecting the rolling shutter door.
[0035] The working principle of the rolling shutter device for cattle shed with self-lubricating function is described in detail below.
[0036] like Figure 1-5As shown, when in use, the rolling door is easily pulled downward by the pull ring on the front bottom end of the rolling door device 1. When the rolling door moves downward, the sliding sleeves 14 on both sides of the frame slats 11 slide on the outer surface of the limiting column 13, which can achieve the limiting effect, so that the rolling door moves downward smoothly without shaking. At the same time, the rotating gear 12 is engaged with the teeth at the rear of the frame slats 11 and gradually moves downward. The clamp 15 drives the rollers 16 to roll on the inner walls of the door frame plate 2 on both sides, thereby enhancing the smoothness of the rolling door moving downward. When it reaches a certain height, the electric telescopic rod 18 is started, and the electric telescopic rod 18 prompts the push-pull plate 19 to move downward. The push-pull plate 19 is used to change the tilt angle of the rotating plates 110 on both sides thereof, and the rotating plate 1 10 pushes the positioning rods 111 on both sides outward so that the other end thereof contacts the inside of the positioning holes 3 on the inner wall of the door frame plate 2, thereby fixing the rolling door in position. When the rolling shutter device 1 moves downward instantly, its bottom end hits the top of the buffer plate 23. The buffer plate 23 moves downward under the pressure, squeezing the spring bodies on both sides. Under the action of the pressure, the rotating shaft 24 at the bottom end prompts the buffer support plate 25 to rotate and change the inclination angle. The other end thereof drives the rotating shaft slider 26 to slide on the outer surface of the sliding rod 22, squeezing the return spring 27 on the other side. The elastic driving force of the return spring 27 is used to prompt the component to return to its original position, thereby achieving the effect of buffering, reducing the impact force, and protecting the rolling shutter door.
[0037] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
