Description

Single-rail three-shaft hinge

Technical Field

The invention particularly relates to a door opening and closing hinge, in particular to a single-rail three-axis hinge.

Background

The embedded hinge is mainly used for an embedded refrigerator or an embedded refrigerator cabinet, the embedded refrigerator generally embeds the whole refrigerator into a customized cabinet, gaps between the outer wall of the refrigerator and the inner wall of the customized cabinet are generally arranged to be small for the fit of the refrigerator embedded into an external cabinet body, and when the door of the refrigerator is opened, the hinged vertical edge of the rotating door can easily hit against the inner wall of the external customized cabinet, so that a certain gap is reserved between the outer wall of the refrigerator and the inner wall of an outer box for smoothly opening the door of the refrigerator, the gap can not influence the use of equipment with small vibration, such as the refrigerator, and the volume of the outer box is forced to be increased by the top, but for some embedded roller washing machines, the gap easily causes the washing machine not to be fitted in the outer box, and huge swinging impact can be generated due to the gap in the working process of the washing machine, so as to generate huge noise, the problem of this, only can customize one set alone in the inside device that stabilizes the washing machine of outer incasement again, the installation is very loaded down with trivial details.

Therefore, aiming at the problems, the problems are fundamentally solved by the track of the door body rotating to open and close, and the smooth opening of the box door is realized on the premise of ensuring the embedded fitting degree of the embedded box body and the customized cabinet.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 7, in the embodiment of the invention, a single-rail three-axis hinge comprises a cabinet body hinged plate 1, a door body mounting plate 2 and a cabinet body mounting plate 6, wherein the cabinet body mounting plate 6 is vertically attached and fixed on the top or bottom edge side of a cabinet body door cavity, the door body mounting plate 2 is horizontally fixed on a front panel of the cabinet body hinged plate 1, the door body mounting plate 2 is integrally embedded and fixedly mounted at the top or bottom of a door body, the cabinet body hinged plate 1 and the door body mounting plate 2 are mutually adjacent and horizontally parallel, a fixed shaft and a fixed rail are clamped between panels on opposite surfaces of the cabinet body hinged plate 1 and the door body mounting plate 2, the fixed rail is formed by a rail frame 3 and a limiting block 4 which are fixed at the same side, the limiting block 4 is fixed at the center position of an inner ring of the rail frame 3, the outer wall of the limiting block 4 and the inner frame of the rail frame 3 enclose the fixed rail, and the lengths of the fixed rail are the same, the fixed shaft comprises three rail shafts 5, each rail shaft 5 is vertically clamped in the fixed rail in a sliding mode at intervals, and the distances between every two adjacent rail shafts 5 are equal.

When the processes from the closing to the opening of the

rails

1 and 2 are anticlockwise rotated, the gravity center of a triangle formed by the three rail shafts 5 and the horizontal height end point is positioned right and right of the center of the limiting block 4, so that the gravity center moves anticlockwise towards the left side when the rails 1 are opened, the right side end of the rail 2 cannot extend outwards too much towards the right side, and the

rails

1 and 2 are ensured to meet the embedded functional requirements.

And each bent part of the fixed rail is an arc end, so that the rail shaft 5 can slide more smoothly when bypassing the adjacent inner wall of the rail frame 3, and the smoothness of the door opening action is ensured.

The cabinet body articulated slab 1 with be equipped with between the door body mounting panel 2 and be used for door body mounting panel 2 to restore to the spring of closed state by the open mode, the spring that sets up can be at door body mounting panel 2 opening in-process deformation tensile storage elastic potential energy, after loosening external force, the spring contracts back and pulls door body mounting panel 2 and resume to initial closed state again.

The cabinet body articulated slab 1 with be equipped with the spacing subassembly that is used for restricting door body mounting panel 2 and opens the angle between the door body mounting panel 2, spacing subassembly can be limiting plate or other stop gear, and main assurance door body mounting panel 2 is opening the in-process, and the door body with door body mounting panel 2 fixed mounting can not bump into outside embedded outer tank wall on, reduces the scratch on door body surface.

The working principle of the invention is as follows: when the door body mounting plate 2 rotates, when the track frame 3 and the limiting block 4 are fixed on the door body mounting plate 1, the track shaft 5 is fixed on the door body mounting plate 2, the door body mounting plate 2 rotates to drive the track shaft 5 to slide in a fixed track enclosed by the track frame 3 and the limiting block 4, the gravity center of an equilateral triangle formed by a plurality of track shafts 5 rotates around the limiting block 4 from the right side of the center of the limiting block 4 by taking the vertical axis of the limiting block 4 as a rotating shaft, and the outer side edge of the side door body mounting plate 2 is turned over at a small angle, therefore, the invention can realize the inner contracting track changing action in the opening process of the door body mounting plate 2 by the matched rotation limiting of the track shaft 5 and the track frame 3, reduce the extending amount of the door body mounting plate 2, ensure the normal opening of the door body, facilitate the embedded more close fitting of the refrigerator, and the whole hinge reduces the occupation of the mounting space by the track frame 3, the limiting block 4 and the track shaft 5, greatly reduced the cost of manufacture, the installation is also simpler, the maintenance of the later stage of also being convenient for simultaneously.
