Problems solved by technology

[0002] Embedded hinges are mainly used for embedded refrigerators or built-in cabinets. Embedded refrigerators generally embed the refrigerator into a customized cabinet. In order to embed precisely, the gap between the outer wall of the refrigerator and the inner wall of the customized cabinet is generally set very small. When the door is opened, the hinged vertical edge of the rotating door can easily hit the inner wall of the external custom cabinet. Therefore, on the premise of ensuring the fit between the refrigerator and the custom cabinet, how to open the door smoothly becomes a problem. question
[0003] Aiming at the problem of forgetting to close the door after the refrigerator is opened, a spring mechanism is generally added between the door and the cabinet body, and the opened and closed door is closed by spring tension, but the deformation of the spring used for reset during the door opening process is generally relatively small Large, the mechanical wear of the spring is large, and the large displacement and deformation of the return lead to a low service life of the spring, which leads to the following two problems. First: when the door is newly purchased, the automatic closing action of the door is large, and the closing action of the door is loud. ;Second: the box door automatically closes after a period of time because the spring loses its elasticity and cannot be closed and tightly attached to the cabinet

Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] see Figure 1~6 , in an embodiment of the present invention, a single-track embedded hinge automatic door closing mechanism includes a door mounting block 1 for mounting on a rotating door body and a cabinet mounting plate 2 for mounting on a matching cabinet body of the door body. The cabinet mounting plate 2 drives the door mounting block 1 to rotate through a horizontally rotating linkage mechanism, and a single guide rail mechanism for guiding the d...

Abstract

A single-rail embedded hinge automatic door closing mechanism comprises a door mounting block single-guide-rail mechanism, a connecting rod and a cabinet mounting plate, a spring mounting rod is fixed to a door mounting block, an angle keeping block is rotationally fixed to the portion, on the opposite side of the spring mounting rod, of a panel of the door mounting block, and the outer wall of the angle keeping block is slidably connected with the top end of a sliding groove rod; when the sliding groove rod moves in the guide sliding groove, the top end of the sliding groove rod drives the angle keeping block to rotate, and a reset spring is installed between the angle keeping block and the spring installation rod. The angle keeping block and the sliding groove rod used for guiding rail transfer act in a matched mode, under the condition that other components are reduced, the automatic door closing action can be achieved, the overall elastic reset state is well combined with the rail transfer action, the spring stretching amount is reduced, the reset spring is evenly stressed in the automatic door closing process, the door closing action is smoother and quieter, the service life of the spring is prolonged.

Description

technical field [0001] The invention specifically relates to a hinge mechanism, in particular to a monorail embedded hinge automatic door closing mechanism. Background technique [0002] Embedded hinges are mainly used for embedded refrigerators or built-in cabinets. Embedded refrigerators generally embed the refrigerator into a customized cabinet. In order to embed precisely, the gap between the outer wall of the refrigerator and the inner wall of the customized cabinet is generally set very small. When the door is opened, the hinged vertical edge of the rotating door can easily hit the inner wall of the external custom cabinet. Therefore, on the premise of ensuring the fit between the refrigerator and the custom cabinet, how to open the door smoothly becomes a problem. question. [0003] Aiming at the problem of forgetting to close the door after the refrigerator is opened, a spring mechanism is generally added between the door and the cabinet body, and the opened and clo...
