Abstract
Description
Technical Field
[0001] This utility model relates to the field of door and window accessories, specifically to door and window hinge structures. Background Technology
[0002] A hinge, also known as a hinge plate, is a mechanical device used to connect two solid objects and allow relative rotation between them. A hinge typically consists of a pair of metal blades and a pin. The two metal blades are connected by the pin and can rotate relative to each other around the pin's axis, thus enabling the opening and closing of the connected object. Hinges are commonly used in doors and windows.
[0003] There are many types of hinges available today. Hinges used on gates are further divided into standard and bearing types based on their application. Bearing types are more commonly used on gates, and they can be made of either brass or stainless steel. Although there are many types of hinges, the hinges currently used on gates still have the following problems:
[0004] Firstly, although existing hinges have been made thicker and reinforced to increase load-bearing capacity, on the one hand, thicker hinges take up more space when installed on the door, and on the other hand, even if the hinge itself is strong enough, since it only connects to one side of the door panel, only the surface of the door panel is subjected to stress, and the connection strength is not high.
[0005] Secondly, existing hinges have limited ability to withstand impacts and prying when subjected to external force or when the door is pried open with external tools. Utility Model Content
[0006] The purpose of this invention is to at least solve the current problems of small connection surface and low connection strength between hinges and door panels.
[0007] To solve the above-mentioned technical problems, the present utility model provides a door and window hinge structure, comprising:
[0008] A fixed bushing has a first fixed hinge piece and a second fixed hinge piece fixedly connected, the first fixed hinge piece and the second fixed hinge piece are at a 90-degree angle; the first fixed hinge piece and the second fixed hinge piece each have at least two first fixing holes.
[0009] A movable bushing is coaxial with the fixed bushing; the movable bushing has a first movable hinge piece and a second movable hinge piece fixedly connected, the first movable hinge piece and the second movable hinge piece are at a 90-degree angle; the first movable hinge piece and the second movable hinge piece each have at least two second fixing holes.
[0010] A connecting shaft that moves through both the fixed bushing and the movable bushing; each end of the connecting shaft has a fixedly connected limiting member; the fixed bushing and the movable bushing are located between the two limiting members;
[0011] The middle hinge is fixedly connected to the second movable hinge, and the middle hinge is at a parallel angle to the first movable hinge.
[0012] As a preferred embodiment of the door and window hinge structure of this utility model, the second fixed hinge piece has at least one anti-pry hole;
[0013] The second movable hinge has at least one anti-pry shaft fixedly connected to it; when the second movable hinge and the second fixed hinge are at a parallel angle, the anti-pry shaft is at least partially located within the anti-pry hole.
[0014] In a preferred embodiment of the door and window hinge structure of this utility model, the first movable hinge piece has at least one first reinforcing fixing hole; the second movable hinge piece has at least one second reinforcing fixing hole, and the first reinforcing fixing hole and the second reinforcing fixing hole are on the same axis.
[0015] As a preferred embodiment of the door and window hinge structure of this utility model, it includes a screw rod, one end of which has a first limiting platform fixedly connected; the other end of the screw rod passes through at least the second reinforcing fixing hole and is located near the first reinforcing fixing hole;
[0016] It includes a nut tube, one end of which has a fixedly connected second limiting platform; the other end of the nut tube passes through at least the first reinforcing fixing hole and is threadedly connected to the screw.
[0017] As a preferred embodiment of the door and window hinge structure of this utility model, it includes a pressure-bearing movable plate, which is installed on the connecting shaft and is located between the fixed bushing and the movable bushing.
[0018] Beneficial effects
[0019] This utility model solves the above-mentioned existing problems and other existing problems not mentioned above, and brings at least the following innovative advantages:
[0020] This utility model's hinge structure, through the provision of a first fixed hinge piece and a second fixed hinge piece, as well as a first movable hinge piece and a second movable hinge piece, allows for connection to two surfaces of the door frame and door panel respectively during application. This increases the contact area between the hinge and the door, thereby enhancing the connection strength. Furthermore, since the second movable hinge piece also has a fixedly connected central hinge piece, when applied to a door, the central hinge piece can be embedded within the door panel, further improving the connection surface and structural strength between the hinge and the door.
[0021] When this utility model door and window hinge structure is applied to a door, the anti-pry shaft is separated from the second fixed connecting piece when the door is open; when the door is closed, the second movable hinge piece and the second fixed hinge piece are at a parallel angle, and at this time the anti-pry shaft is inserted into the anti-pry hole. The anti-pry shaft and anti-pry hole improve the structural strength and capability in terms of impact and pry resistance.
[0022] The door and window hinge structure of this utility model, through the first and second reinforcing fixing holes provided in the first and second movable hinge pieces, can be used to install nut tubes and screws, thereby forming a solid frame structure between the first movable hinge piece, the second movable hinge piece and the middle hinge piece, further enhancing the overall stability.
