Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a simple hinge door closer. Background Art

[0002] Existing hinges are widely used in furniture and electrical appliances, especially refrigerators. A hinge connects the cabinet and door. To ensure the door automatically closes when slightly opened, a door closer is installed on the hinge. These door closers generally come in the following configurations: 1. Magnetic strip; 2. Plastic hook; 3. Vertical spring-driven. However, regardless of which of these power mechanisms is used, hinged door closers have the following drawbacks in practical applications:

[0003] 1) Complex structure and high manufacturing cost;

[0004] 2) Hinges are generally assembled with ordinary steel plates, which are complicated to assemble, have poor flexibility, and are prone to breakage, affecting the service life of the product.

[0005] 3) The door opening range is small, and it is difficult to open it at a wide angle, which has great limitations in use. If a wide-angle opening can be achieved, in order to avoid interference between the door body and the cabinet body, the gap between the door body and the cabinet body will be increased, which will reduce the use effect of the product.

[0022] The present invention will be further described below in conjunction with the accompanying drawings.

[0023] According to the attached Figures 1 to 5 As shown in the figure, the simplified hinged door closer of this utility model comprises a mounting plate 1 mounted on the cabinet body and a rotating device mounted on the door body. The mounting plate 1 is provided with a main shaft 2, which is integrally formed with the mounting plate 1 and is die-cast from a zinc-aluminum-copper alloy. This simple structure allows for easy assembly and high flexibility, ensuring product quality.

[0024] Reference Figures 1 to 5 As shown, the rotating device includes a guide block 3 and a connecting rod 4. The guide block 3 is mounted on the door body, the positioning end of the connecting rod 4 is rotatably connected to the mounting plate 1, and the connecting end of the connecting rod 4 is connected to the connecting end of the guide block 3. The guide block 3 is provided with a guide special-shaped groove 5 that is slidably connected to the main shaft 2.

[0025] The positioning end of the connecting rod 4 is rotatably connected to the mounting plate 1 via a positioning shaft 6 , and the connecting end of the connecting rod 4 is connected to the connecting end of the guide block 3 via a connecting shaft 7 .

[0026] In actual application, the positioning shaft 6 is fixedly mounted on the mounting plate 1 , and the connecting shaft 7 is fixedly mounted on the connecting rod 4 .

[0027] By coordinating the structures of the mounting plate 1 with the main shaft 2, the guide block 3 and the connecting rod 4, and utilizing the transmission relationship between the main shaft 2, the connecting rod 4 and the guide block 3, the use of gaskets is reduced, the structure is simplified, and the door body rotates stably and smoothly during opening and closing, thereby ensuring the use effect of the product.

[0028] Reference Figures 1 to 5 As shown in the figure, the shape of the guide special-shaped groove 5 is consistent with the opening and closing path of the door body. The guide special-shaped groove 5 includes a fixed-point opening and closing groove 51, a small-amplitude opening and closing groove 52, and a large-amplitude opening and closing groove 53. The small-amplitude opening and closing groove 52 and the large-amplitude opening and closing groove 53 are respectively located on both sides of the fixed-point opening and closing groove 51. The main shaft 2 slides between the fixed-point opening and closing groove 51, the small-amplitude opening and closing groove 52, and the large-amplitude opening and closing groove 53 as the door body opens and closes.

[0029] When the door body is closed, the main shaft 2 is relatively clamped in the fixed opening and closing slot 51, which helps the door body to close on the cabinet body, and has a certain locking force to ensure the use effect of the product. When the door body is opened, the guide block 3 rotates accordingly, pushing the main shaft 2 to move away from the fixed opening and closing slot 51 and slide into the small opening and closing slot 52; thereby increasing the gap between the door body and the cabinet body. As the door body is relatively opened to 90 degrees, the main shaft 2 slides away from the small opening and closing slot 52 and is clamped on the fixed opening and closing slot 51; the door body is kept hovering during opening, which improves the stability of use. At this time, the door body is opened outward again, and the main shaft 2 moves away from the fixed opening and closing slot 51 and slides into the large opening and closing slot 53, realizing a wide-angle opening of the door body, which is convenient to use, and achieves non-interference between the door body and the cabinet body during opening, and reduces the gap, ensuring the use quality of the product.

[0030] Reference Figures 1 to 5 As shown, in further detail, the mounting plate 1 is provided with a step 11 for reinforcing the structural strength while limiting the swing amplitude of the linkage rod 4, the main shaft 2 is provided on the step 11, and the linkage rod 4 is connected to the side wall of the step 11 as the door body opens.

[0031] Under the action of the step 11, the structural strength of the mounting plate 1 is enhanced, and the swing amplitude of the linkage rod 4 is limited, thereby limiting the opening angle of the door body, making it easy to use and ensuring the use of the product.

[0032] The above specific embodiments are only specific implementation methods with better effects of the present invention. Any structure that is the same or equivalent to the simple hinge door closer of the present invention is within the protection scope of the present invention.
