[0002] Door openers play an important role in modern life and are commonly used in various areas where doors need to open and close automatically after receiving a signal. Among them, sliding door openers are a type of door opener that uses signal components such as infrared sensors to receive external signals to determine whether there are people or objects, and then controls the opening and closing of the door by a motor.

[0003] Patent publication number CN222501433U discloses a centrally located electronically controlled industrial door opener, including a top plate. Above the top plate are two lead screws arranged side-by-side with opposite rotation directions. The opposite ends of the two lead screws are respectively fixedly connected to a first bevel gear. The two first bevel gears mesh with a second bevel gear, which is fixedly connected to one end of a rotating shaft. The other end of the rotating shaft passes through an electronic limiting mechanism and is fixedly connected to the output end of a reduction motor. Each of the two lead screws is threadedly connected to a moving block. A connecting plate is fixedly connected to the bottom of each moving block, and a door mounting bracket is fixedly connected to the bottom of the connecting plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1 to 5 This utility model provides a limiting structure for an industrial door servo opening machine: It includes a top plate 2, with two side plates 1 symmetrically fixed to the bottom surface of the top plate 2. Each side plate 1 has an inner cavity, and a door panel 11 is slidably connected within each cavity. A guide groove 8 extends through the top surface of the top plate 2, and the two door panels 11 are slidably connected within the guide groove 8. Two horizontally symmetrical toothed grooves are provided on the inner wall of the guide groove 8, each groove meshing with a gear. An arc-shaped groove is horizontally formed on the front and rear sides of each door panel 11, and a gear is rotatably connected within each arc-shaped groove. A driving component is connected to the top surface of the two door panels 11, and the driving component is fixedly connected to the top surface of the top plate 2. The inner wall of the groove 8 is symmetrically telescopically connected to two first buffer plates 10. The inner wall of the guide groove 8 is horizontally opened with multiple equidistant array blind holes 20. Each blind hole 20 is slidably connected to a buffer member. The ends of multiple buffer members are jointly fixed to a first buffer plate 10. The inner side of one of the door panels 11 is provided with a groove 13. The groove 13 abuts against a second buffer plate 12. The second buffer plate 12 is telescopically connected to the other door panel 11. The side of the first buffer plate 10 is horizontally fixed with multiple equidistant array first damping rods 18. Each first damping rod 18 is fitted with a second spring 17 on its outer edge. The ends of multiple first damping rods 18 are all fixed to the side of the other door panel 11.

[0024] The buffer includes a second damping rod 23 horizontally fixed in the blind hole 20, a third spring 22 sleeved on the outer edge of the second damping rod 23, a fixing plate 21 fixedly connected to the end of the third spring 22, the fixing plate 21 fixedly connected to the end of the second damping rod 23, a support shaft 19 fixedly connected to the end of the fixing plate 21, and the support shaft 19 fixedly connected to the first buffer plate 10.

[0025] The driving component includes a drive motor 3 horizontally fixed to the top surface of the top plate 2. The output end of the drive motor 3 is connected to a threaded rod 4. The end of the threaded rod 4 is rotatably connected to a support plate 9. The support plate 9 is fixed to the top surface of the top plate 2. Two screw sleeves 6 are symmetrically threaded on the outside of the threaded rod 4. The threads of the two screw sleeves 6 have opposite directions. Pressure sensors 5 are fixedly connected to both sides of each screw sleeve 6. A limiting block 7 is rotatably fitted on the outer edge of the threaded rod 4. The limiting block 7 is fixed to the top surface of the top plate 2 and is located between the two screw sleeves 6. The two screw sleeves 6 are slidably connected to the top surfaces of the two door panels 11. The top surface of the door panel 11 is provided with a sliding groove 14. A slider 16 is slidably connected in the sliding groove 14. The slider 16 is fixedly connected to the bottom surface of the screw sleeve 6. A first spring 15 is fixed together with the inner wall of the sliding groove 14 and the slider 16.

[0026] By telescopically connecting the second buffer plate 12 within the guide groove 8 via a buffer member, setting a groove 13 and a first buffer plate 10 between the two door panels 11, and setting pressure sensors 5 at both ends of the two screw sleeves 6, the screw sleeves 6 are slidably connected to the door panels 11. When the door opener is opening and closing, it plays a limiting role on the door panels 11, and at the same time plays a buffering role on the impact force of the door panels 11 when opening and closing, preventing the door panels 11 from colliding and causing damage to the door panels 11, thereby improving the service life of the door opener.

[0027] Working principle: When the door panel 11 is opened, the drive motor 3 drives the threaded rod 4 to rotate. The threaded rod 4 drives the two screw sleeves 6 with opposite thread directions to move in opposite directions. The two screw sleeves 6 drive the two door panels 11 to move in opposite directions within the guide groove 8, so that the door panels 11 are retracted into the storage cavity of the side panel 1. When the door panel 11 moves to the edge of the guide groove 8, the side of the door panel 11 will first contact the second buffer plate 12. The second buffer plate 12 buffers the impact force of the door panel 11 through the second damping rod 23 and the third spring 22. The second damping rod 23 is compressed by the force and the third spring 22 is compressed, blocking the door panel 11 and stopping it. The screw sleeve 6 continues to move under the action of the first spring 15 in the slide groove 14. At the same time, the speed of movement will be reduced by the resistance of the first spring 15. When the pressure sensor 5 on the outside of the screw sleeve 6 contacts the support plate... When the screw sleeve 6 contacts the inner side of the drive motor 3, the drive motor 3 stops, causing the screw sleeve 6 to stop moving. When the door panel 11 needs to be closed, the drive motor 3 drives the two door panels 11 to move relative to each other in the guide groove 8. Before the two door panels 11 come into contact, the first buffer plate 10 on one of the door panels 11 will first abut against the groove 13 in the other door panel 11. At the same time, the first damping rod 18 and the second spring 17 are compressed by force to buffer the impact force of the two door panels 11 when they are closed, and slow down the speed at which the two door panels 11 come into contact with each other until the two door panels 11 come into contact with each other. When the two door panels 11 come into contact with each other, the pressure sensor 5 on the inner side of the screw sleeve 6 slowly comes into contact with the limit block 7 under the blocking action of the first spring 15, the second spring 17 and the first damping rod 18. After the pressure sensor 5 detects the pressure, the drive motor 3 stops, thus completing the closing of the door panel 11.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
