In addition, the terms such as "upper", "lower", "left", "right" and "middle" used in the present specification are for convenience of description only, and are not intended to limit the scope of the present invention, and changes or modifications of the relative relationship thereof may be regarded as the scope of the present invention without substantial changes in the technical contents.
In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "connected" and "connected" are to be interpreted broadly, e.g., as being fixed or detachable or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.
The first embodiment is as follows:
as shown in fig. 1 and 2, the two rotary hinges capable of bearing a large load according to the present invention are used to connect a box body 1 and a box door 2 (the box door 1 is a box door 1 that is opened by rotating from top to bottom), and are respectively and symmetrically installed on the left and right sidewalls inside the box body 1 to stably support the box door 2, thereby ensuring stability and smoothness of opening and closing the box door 2.
Each rotary hinge comprises a hinge fixing plate 3, a hinge baffle plate 4, a hinge fixing strip 5, a hinge movable strip 6 and a hinge movable sheet 7.
Hinge fixed plate 3 transversely fixes on 1 left side wall of box or right side wall (through the screw), is equipped with the spout on hinge fixed plate 3 lateral wall, spout both ends opening and its front end mouth are towards the case mouth of box 1. The hinge fixing plate 3 is vertical to the plane of the box opening of the box body 1.
The hinge baffle 4 is fixed on the side wall of the hinge fixing plate 3 (through screws) and covers the sliding groove. The two hinge baffles 4 are vertically fixed on two sides of the side wall of the hinge fixing plate 3 respectively and used for limiting the transverse sections of the hinge movable strips 6, so that the transverse sections of the hinge movable strips 6 can only slide along the sliding grooves or the length direction of the hinge fixing plate 3.
The hinge fixing strip 5 is arranged on the box door 2 corresponding to the hinge fixing plate 3 (fixed on the inner wall of the box door 2 through a screw).
The hinge movable strip 6 is in a 7-shaped structure, a transverse section (from a front port of the sliding chute) of the hinge movable strip extends into the sliding chute and can slide back and forth in the sliding chute (namely can shuttle in the sliding chute), and the lower end of a vertical section of the hinge movable strip (after being matched by a movable nut, a gasket and a screw) is hinged to one end, close to the box body 1, of the hinge fixing strip 5. The transverse section and the vertical section of the hinge movable strip 6 are mutually perpendicular, the transverse section (the hinge fixing plate 3 and the sliding groove) of the hinge movable strip 6 is perpendicular to the plane of the box opening, and the optimized structure can ensure that the box door 2 is more smooth and flexible.
The hinge movable piece 7 is composed of two strip-shaped pieces which can be overlapped together in a rotating mode, one ends of the two strip-shaped pieces are hinged to each other through a hinge movable pin shaft 8, and the other ends of the two strip-shaped pieces are hinged to one end, away from the box body 1, of the vertical section of the hinge movable strip 6 and one end, away from the box body 1, of the hinge fixed strip 5 respectively (after being matched through a movable nut, a gasket and a screw) after being unfolded towards two sides. The two strip-shaped pieces can rotate along with the rotation of the box door 2, and can be overlapped together after the box door 2 is closed. The hinge movable pin shaft 8 is sleeved with a gasket positioned between the two strip-shaped pieces, and the gasket can prevent the two pieces from being clamped when the two pieces are overlapped in a rotating way.
As shown in fig. 2, when the door 2 is closed, the door 2 is first rotated and lifted from bottom to top, and the two strip-shaped pieces of the hinge movable piece 7 gradually approach and overlap with each other with the hinge movable pin 8 as the center until the door 2 is parallel to the plane of the door opening, and then the two strip-shaped pieces completely overlap with each other; and then, the box door 2 is transversely pushed towards the box opening to be close to and attached to the box opening, the hinge movable strip 6 is pushed to transversely move through the hinge fixing strip 5 in the process that the box door 2 moves towards the box opening, the transverse section of the hinge movable strip 6 is retracted into the sliding groove until the box door 2 is completely closed, and finally the box door 2 is locked on the box body 1.
When opening the chamber door, earlier outwards stimulate chamber door 2 lateral shifting certain distance, make one section distance after the outside roll-off spout of horizontal section of hinge movable strip 6, again from the top down rotation open chamber door 2, 2 in-process of chamber door, two rectangular shape pieces of hinge movable sheet 7 use hinge activity round pin axle 8 slowly outwards to expand as the center, open until chamber door 2 completely, chamber door 2 receives the tractive of hinge movable sheet 7, can hang fixedly for a long time and can not lead to dropping because of hang the time overlength.
Example two:
the difference between this embodiment and the first embodiment is:
in order to enhance the bearing capacity of the hinge during rotation, the rear end of the transverse section of the hinge movable strip 6 extends out of the sliding groove and is provided with a limit screw 9 for preventing the rear end of the hinge movable strip 6 from sliding into the sliding groove, and the limit screw 9 can limit the position (the limit screw 9 is blocked by the hinge baffle plate 4 and is difficult to slide into the sliding groove, so that the transverse section of the hinge movable strip 6 can be limited from sliding out of the sliding groove excessively) and bear the weight (the weight of the bearing box door 2). When the box door 2 is opened, the existence of the limit screw 9 can avoid the box door 2 from being excessively pulled open (the transverse section of the limit hinge movable strip 6 excessively slides out), and meanwhile, the box door 2 can be supported by the auxiliary hinge movable sheet 7 after the box door 2 is completely opened.
Other parts of the utility model not described in detail are conventional techniques known to the person skilled in the art.
It is to be noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
The scope of the present invention is not limited to the technical solutions disclosed in the embodiments, and any modifications, equivalent substitutions, improvements, etc. made to the above embodiments according to the technical spirit of the present invention fall within the scope of the present invention.
