Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be described in detail below. It is to be understood that the embodiments described are only some embodiments of the invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The specific embodiment of the present invention provides a hinge, as shown in fig. 2 and fig. 3, including a first connecting plate 1, a second connecting plate 2, a first transmission rod 3, a second transmission rod 4, a third transmission rod 5 and a fourth transmission rod 6; the first connecting plate 1 and the second connecting plate 2 are used for connecting a window frame and a window sash to achieve the purpose of hinging the window sash; in particular, as shown in fig. 2 and 3, the first connecting plate 1 is used for connecting a window frame, the second connecting plate 2 is used for connecting a window sash, the first connecting plate 1 is connected with the second connecting plate 2 through a plurality of transmission rods, the first end 7 of the first connecting plate 1 is hinged with the tail end 10 of the second connecting plate 2 sequentially through the second transmission rod 4 and the third transmission rod 5, specifically, one end of the second transmission rod 4 is hinged with the first end 7 through the first hinge 11, the second transmission rod 4 rotates around the first hinge 11 relative to the first connecting plate 1, the other end of the second transmission rod 4 is hinged with one end of the third transmission rod 5 through the second hinge 12, the second transmission rod 4 can rotate relative to the third transmission rod 5 around the second hinge 12, the other end of the third transmission rod 5 is hinged with the tail end 10 through the third hinge 13, and the third transmission rod 5 can rotate relative to the tail end 10 around the third hinge 13.
The same sequential hinging way as above is adopted, a first transmission rod 3 and a fourth transmission rod 6 are further connected between the first connecting plate 1 and the second connecting plate 2, and a second end 8 of the first connecting plate 1 and a head end 9 of the second connecting plate 2 are sequentially hinged through the first transmission rod 3 and the fourth transmission rod 6; specifically, one end of each of the first transmission rods 3 is hinged to the second end 8 through a fourth hinge 14, so that the first transmission rods 3 and the first connecting plate 1 can rotate relatively around the fourth hinge 14, the other ends of the first transmission rods 3 are hinged to one end of the fourth transmission rod 6 through a fifth hinge 15, so that the first transmission rods 3 and the fourth transmission rods 6 can rotate relatively around the fifth hinge 15, and finally, the other ends of the fourth transmission rods 6 are hinged to the multi-head end 9 of the second connecting plate 2 through a sixth hinge 16, so that the fourth transmission rods 6 and the second connecting plate 2 can rotate relatively around the sixth hinge 16; it is worth to be noted that the first end 7 of the first connecting plate 1 is close to the head end 9 of the second connecting plate 2, the tail end 10 of the second connecting plate 2 is far away from the first end 7 of the first connecting plate 1, the length of the second transmission rod 4 is larger than that of the third transmission rod 5, the length of the fourth transmission rod 6 is larger than that of the first transmission rod 3, then the middle of the second transmission rod 4 is hinged to the middle of the fourth transmission rod 6, the hinging at the position is convenient to limit the relative rotation direction of the hinged positions between the transmission rods and the connecting plates, the situation that the hinge is blocked due to the reverse rotation of the hinged positions after the hinge is excessively unfolded is avoided, and the hinged positions can only rotate in one direction and the opposite direction according to the connection mode to correspond to the opening.
The hinge formed by the above structure can realize normal opening and closing of the window sash and only rotate at the hinge point in the opening and closing process through the hinge mode between the plurality of transmission rods and the two connecting plates, is greatly different from the structure form of the vacancy draw groove 25 used in the prior art, can avoid the defect of insufficient structural strength of the vacancy draw groove 25, and can avoid the friction noise generated when the connecting piece slides in the vacancy draw groove 25, the frequent friction also easily causes the damage of the hinge, and the connecting piece in the vacancy draw groove 25 is used by being matched with a plastic piece, so that the hinge does not have fireproof performance; the hinge that this application provided all satisfies people to its demand from all aspects, and the structure is more suitable, possesses bigger bearing capacity, and the noise is little and all metal material fire behavior is more superior.
The hinge provided in the embodiment of the present application may also be designed to have the following length relationship, which is only a simple description of the approximate length relationship, and specifically, the distance between the first hinged part 11 and the second hinged part 12 is equal to the sum of the distance between the second hinged part 12 and the third hinged part 13 plus the distance between the third hinged part 13 and the sixth hinged part 16, and a certain error exists according to actual conditions, which falls within a normal protection range; the distance between the fifth hinge 15 and the sixth hinge 16 is equal to the sum of the distance between the first hinge 11 and the fourth hinge 14 and the distance between the fourth hinge 14 and the fifth hinge 15, and as the length corresponding relationship is set, the first connecting plate 1 and the second connecting plate 2 can be vertically corresponding and completely overlapped under the condition that the hinge is completely folded, and the length relationship in the specific design can be adjusted according to the actual condition, and only the requirement that the first connecting plate 1 and the second connecting plate 2 can be overlapped is met.
