Description

Technical Field

[0001] This utility model relates to the field of door opener technology, specifically a top-mounted door opener. Background Technology

[0002] In modern life, door openers are widely used, covering residential, commercial, and industrial plants. Traditional door opener installation methods are diverse, such as underground and wall-mounted types, but these methods have revealed many problems in actual use. Underground door openers are installed below ground, which is relatively concealed in appearance, but the installation process is complex and requires a lot of ground excavation work. This not only results in high construction costs and long construction periods, but also makes subsequent maintenance difficult. Once a malfunction occurs, repairs require a lot of manpower and resources to excavate the ground, which has a significant impact on the surrounding environment. Wall-mounted door openers are usually installed on the wall on the side of the door, occupying a lot of space, which is not suitable for some space-constrained places, and may also affect the aesthetics of the door area. Therefore, a top-mounted door opener is needed, which is installed above the door frame for use.

[0003] However, due to the poor adjustability of the existing top-mounted door opener, it is not convenient to adjust the length of the connecting rod according to the needs of use. In actual use, a fixed length connecting rod is often used for installation or adjustment by bolt tightening. The adjustment is not convenient enough. When it is necessary to open door panels of different widths, it is necessary to install connecting rods of matching length one by one or adjust them by bolts, which affects the convenience of installation and use. Utility Model Content

[0004] The purpose of this utility model is to provide a top-mounted door opener to solve the problem mentioned in the background art that the existing technology is not convenient to adjust the length of the connecting rod according to the usage needs.

[0021] 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.

[0022] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A top-mounted door opener includes a protective housing 1. Mounting brackets 2 are fixedly installed on the inner walls of both sides of the protective housing 1. A drive motor 3 is fixedly installed in the middle of the mounting brackets 2. A coupling 4 is fixedly installed on the output shaft end of the drive motor 3, extending to the top of the protective housing 1. A connecting rod 5 is fixedly installed on the top of the coupling 4. A support sleeve 6 is fixedly installed on one side of the connecting rod 5. An adjusting bracket 7 is sleeved on one side of the support sleeve 6, extending into the interior of the support sleeve 6. Several positioning through holes 8 are evenly distributed at the top of the adjusting bracket 7. A connecting through hole 9 is formed at the top of the support sleeve 6. Connecting springs 10 are fixedly installed on both sides of the connecting through hole 9 at the top of the support sleeve 6. A support connecting plate 11 is fixedly installed at the top of the connecting spring 10, and a positioning rod 12 is fixedly installed at the bottom of the support connecting plate 11. The positioning rod 12 passes through the connecting through hole 9 and is movably connected inside the positioning through hole 8. When the support connecting plate 11 is pulled upward, the support connecting plate 11 drives the positioning rod 12 to overcome the elastic force of the connecting spring 10, so that the positioning rod 12 is disengaged from the positioning through hole 8 on the adjusting bracket 7. At this time, the adjusting bracket 7 can freely extend and retract within the support sleeve rod 6. The drive motor 3 starts to work, and its output shaft generates rotational power. This power is transmitted to the connecting rotating rod 5 through the coupling 4. The connecting rotating rod 5 drives the support sleeve rod 6 and the adjusting bracket 7 to move, and then pulls or pushes the door panel through the support movable rod 13 and the connecting bracket 14.

[0024] The bottom end of the adjusting bracket 7, away from the supporting sleeve rod 6, is connected to a supporting movable rod 13 by a pin. A connecting bracket 14 is fixedly installed on the side of the supporting movable rod 13 away from the adjusting bracket 7. A mounting positioning block 15 is connected to one side of the connecting bracket 14 by a pin. Two mounting through holes 16 are opened on one side of the mounting positioning block 15. Mounting lugs 17 are fixedly installed on both sides of the protective shell 1. Two mounting screw holes 18 are opened on one side of the mounting lugs 17 and penetrate through the mounting lugs 17. Two connecting wire holes 19 are opened on one side of the protective shell 1.

[0025] In this embodiment, a top-mounted door opener is used by first screwing bolts into the mounting screw holes 18 on the mounting lug 17 to install the protective housing 1 on the top of the door frame. Then, the mounting positioning block 15 is connected to the back of the door panel by screwing bolts into the mounting through hole 16. Subsequently, an external power supply is connected through the connecting wire hole 19 to power the drive motor 3, and the drive motor 3 is electrically connected to the access control system for easy control. When dealing with door panels of different widths, if the length of the connecting rod needs to be adjusted, the support connecting plate 11 is pulled upwards. The support connecting plate 11 drives the positioning rod 12 to overcome the elastic force of the connecting spring 10, causing the positioning rod 12 to disengage from the positioning through hole 8 on the adjusting bracket 7. At this time, the adjusting bracket 7 can freely extend and retract within the support sleeve 6. After adjusting the adjusting bracket 7 to a suitable length to match the door panel width, the support connecting plate 11 is released. When the connecting plate 11 and the connecting spring 10 return to their original deformation, the supporting connecting plate 11 moves downward. The positioning rod 12 is re-inserted into the corresponding positioning through hole 8, completing the rapid positioning and fixing of the connecting rod length. This ensures that the door opener can stably drive door panels of different widths to open and close. When the door opener is needed to open or close the door panel, the drive motor 3 starts to work, and its output shaft generates rotational power. This power is transmitted to the connecting rotating rod 5 through the coupling 4. The connecting rotating rod 5 drives the supporting sleeve rod 6 to rotate. Since the adjusting bracket 7 is sleeved and connected to the supporting sleeve rod 6, and the adjusting bracket 7 is connected to the mounting positioning block 15 through the supporting movable rod 13 and the connecting bracket 14, and the mounting positioning block 15 is fixed to the door panel, the rotation of the supporting sleeve rod 6 will drive the adjusting bracket 7 to move. In turn, the supporting movable rod 13 and the connecting bracket 14 will pull or push the door panel to realize the opening and closing action of the door panel.
