Description

Technical Field

[0001] This utility model belongs to the field of electric sliding door technology, and in particular relates to a 90-degree right-angle mounting component for an electric sliding door. Background Technology

[0002] Electric sliding doors (also called electric sliding doors, automatic sliding doors, or electric push-pull doors) are a common type of automated door, widely used in commercial buildings, office buildings, shopping malls, hospitals, hotels, and other places. Their main feature is that an electric drive system enables the door to automatically slide open and close, providing convenience, energy efficiency, and security.

[0003] Existing technologies make it difficult to achieve a 90-degree right-angle rotation of electric sliding doors. Therefore, we propose a 90-degree right-angle mounting component for electric sliding doors. Utility Model Content

[0004] The purpose of this invention is to provide a 90-degree right-angle mounting assembly for an electric sliding door. This is achieved through the coordinated operation of a bidirectional motor, a threaded rod, threaded sleeves, and extension rods. When the bidirectional motor is activated, it drives the threaded rod to rotate. This rotation causes two threaded sleeves to move horizontally under the constraint of the rotating door. The horizontal movement of the two threaded sleeves then drives two extension rods to move horizontally, which in turn drives a rotating shaft to move horizontally. This horizontal movement of the rotating shaft, in turn, drives the rotating door to move horizontally within a sliding groove. The coordinated operation of these components allows the rotating door to open by a 90-degree angle. This overall structure ensures the efficiency and stability of the device, making it suitable for automatic door systems requiring frequent opening and closing, and solving existing problems.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a 90-degree right-angle mounting component for an electric sliding door, including a door frame, and an automatic door opening and closing device is provided on the top of the door frame;

[0007] The automatic door opening and closing device includes a fixed plate, the top of which is fixedly connected to the top of the door frame. A bidirectional motor is fixedly connected to the side of the fixed plate, and a threaded rod is fixedly connected to the output shaft of the bidirectional motor. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod, and an extension rod is fixedly connected to the circumferential surface of the threaded sleeve. A rotating shaft is rotatably connected to the bottom of the extension rod, and a rotating door is fixedly connected to one end of the rotating shaft. A rotating shaft is fixedly connected to the bottom of the rotating door, and a sliding groove box is slidably connected to one end of the rotating shaft. The main function of this automatic door opening and closing device is to drive the threaded rod with the bidirectional motor, thereby achieving the automatic opening and closing function of the rotating door through the extension rod, rotating shaft, and other components. The design of the sliding groove box allows the rotating door to slide smoothly, and the overall structure ensures the high efficiency and stability of the device, making it suitable for automatic door systems that require frequent opening and closing.

[0008] Furthermore, two threaded sleeves are provided, symmetrical about the longitudinal axis of the bidirectional motor. This symmetrical arrangement of the two threaded sleeves is primarily to ensure the balance, stability, and uniformity of the automatic door opening and closing device. In high-frequency and high-load operating environments, this effectively improves the device's service life and performance stability, and ensures smooth door opening and closing.

[0009] Furthermore, a spring is fixedly connected to the inner side of the sliding box, with one end of the spring located on the displacement trajectory of the rotating shaft. The spring improves the performance and service life of the entire automatic door opening and closing device by providing restoring force, mitigating vibration, ensuring stable door closure, and reducing wear. It helps the door move more smoothly and flexibly, and reduces potential mechanical shocks and abnormalities during opening and closing.

[0010] Furthermore, two versions of the rotating door, rotating shaft, sliding box, extension rod, and spring are provided, with each of these components corresponding to one of the two threaded sleeves. By providing two versions of each component, corresponding to two threaded sleeves, bidirectional balanced and symmetrical door opening and closing movements can be achieved. This design ensures smooth and balanced door movement, extends the service life of the equipment, reduces uneven loads, jamming, and vibration, and improves the overall system stability and durability.

[0011] Furthermore, a maintenance device is provided on the side of the door frame. This device includes an oil pump housing, which is fixedly connected to the side of the door frame. A piston at one end of the oil pump housing is slidably connected to a force-bearing rod, and an oil supply pipe is connected through the other end of the oil pump housing. A connecting rod is fixedly connected to the side of the extension rod, and a rotating column is rotatably connected to one end of the connecting rod. A striker is fixedly connected to the circumferential surface of the rotating column, and a nozzle is connected through the circumferential surface of the oil supply pipe. The function of this maintenance device is to provide lubrication and pressure through the oil pump system to ensure the long-term stable operation of all moving parts of the automatic door opening and closing device, reduce wear, and potentially increase service life and operating efficiency.

[0012] Furthermore, a return spring is fixedly connected to the circumferential surface of the force-bearing rod, and one end of the return spring is fixedly connected to one end of the oil pump housing. This return spring design helps to provide restoring force, buffering effect, and ensure the stable operation of the mechanical system.

[0013] Furthermore, a return torsion spring is fixedly connected to the circumferential surface of the rotating column, with one end of the return torsion spring fixedly connected to the side of the connecting rod, and one end of the force-bearing rod located on the displacement trajectory of the impact rod. These designs enhance the stability, resilience, and reliability of the system, ensuring that each component can accurately reset and maintain coordinated operation when subjected to external forces.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model achieves its functionality through the coordinated operation of components such as a bidirectional motor, a threaded rod, threaded sleeves, and extension rods. When the bidirectional motor is activated, it drives the threaded rod to rotate. This rotation causes two threaded sleeves to move horizontally under the constraint of the revolving door. The horizontal movement of the two threaded sleeves then drives two extension rods to move horizontally, which in turn drives a rotating shaft to move horizontally. This horizontal movement of the rotating shaft, in turn, drives the revolving door to move horizontally within a sliding box. The coordinated operation of these components allows the revolving door to rotate and open by 90 degrees. This overall structure ensures the high efficiency and stability of the device, making it suitable for automatic door systems requiring frequent opening and closing.

[0016] 2. This utility model achieves its effect through the coordinated operation of components such as a bidirectional motor, a threaded rod, a threaded sleeve, and a connecting rod. When the bidirectional motor is started, it drives the threaded rod to rotate. The rotation of the threaded rod causes the threaded sleeve to move horizontally, which in turn causes the connecting rod to move horizontally. The horizontal movement of the connecting rod causes the rotating column to move horizontally, which in turn causes the impact rod to move horizontally. The horizontal movement of the impact rod pushes the force-bearing rod in a piston-like motion within the oil pump box, thereby delivering lubricating oil to the oil supply pipe. The lubricant is then sprayed onto the surface of the threaded rod through a nozzle for lubrication. This reduces wear and may increase service life and operating efficiency.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

The design of the sliding groove box 29 allows the rotating door 27 to slide smoothly. The overall structure ensures the high efficiency and stability of the device, making it suitable for automatic door systems that require frequent opening and closing.

[0031] Two threaded sleeves 24 are provided, symmetrical about the longitudinal axis of the bidirectional motor 22.

By setting two of these components and having them correspond to two threaded sleeves 24, bidirectional balanced and symmetrical opening and closing movements can be achieved. This design ensures smooth and balanced door movement, extends the service life of the equipment, reduces uneven loads, jamming, and vibration, and improves the overall system stability and durability.

[0034] A maintenance device 3 is provided on the side of the door frame 1. The maintenance device 3 includes an oil pump box 31, which is fixedly connected to the side of the door frame 1. One end of the oil pump box 31 is slidably connected to a force-bearing rod 32, and the other end of the oil pump box 31 is connected through an oil supply pipe 33.

These designs enhance the stability, resilience, and reliability of the system, ensuring that each component can accurately reset and maintain coordinated operation when subjected to external forces.

[0037] A specific application of this embodiment is as follows: the bidirectional motor 22 is started, and the bidirectional motor 22 drives the threaded rod 23 to rotate. The rotation of the threaded rod 23 causes the two threaded sleeves 24 to move horizontally under the restriction of the rotating door 27. The horizontal movement of the two threaded sleeves 24 causes the two extension rods 25 to move horizontally. The horizontal movement of the two extension rods 25 causes the rotating shaft 26 to move horizontally. The horizontal movement of the rotating shaft 26 causes the rotating door 27 to move horizontally. The rotating door 27 causes the rotating shaft 28 to move horizontally in the sliding box 29. The two cooperate with each other to realize the rotation of the rotating door 27 by 90 degrees.

[0038] The bidirectional motor 22 is started, driving the threaded rod 23 to rotate. The rotation of the threaded rod 23 causes the threaded sleeve 24 to move horizontally. The horizontal movement of the threaded sleeve 24 causes the connecting rod 34 to move horizontally. The horizontal movement of the connecting rod 34 causes the rotating column 35 to move horizontally. The horizontal movement of the rotating column 35 causes the impact rod 36 to move horizontally. The horizontal movement of the impact rod 36 pushes the force-bearing rod 32 to move like a piston in the oil pump box 31, thereby delivering lubricating oil to the oil supply pipe 33. The lubricant is sprayed onto the surface of the threaded rod 23 through the nozzle 37 for lubrication. When the impact rod 36 encounters strong resistance, the rotating column 35 rotates, and the impact rod 36 folds. When the force-bearing rod 32 loses its thrust, the return spring 38 uses its own elasticity to drive the force-bearing rod 32 to return to its original position. When the impact rod 36 loses resistance, the return torsion spring 39 drives the rotating column 35 to rotate and return to its original position. The return of the rotating column 35 drives the impact rod 36 to return to its original position.
