Description

Technical Field

[0001] The utility model relates to the field of hinges, in particular to a novel bolt hinge. Background Art

[0002] Most hinges currently used are hinges or cylindrical hinges. Cylindrical hinges need to be paired with the door leaf and numbered, and they cannot be interchanged. Furthermore, they cannot adjust the width and verticality of the door. Hinges or cylindrical hinges must be shipped as a set. Mixing them up can lead to installation errors, as the hinge's mounting holes won't align, and the cylindrical hinge won't fit. Hinges rely on balls and bearings to open and close. Over time, with frequent opening and closing, the bearings and balls wear out, causing the door leaf to wobble, become loose, and lose stability. Cylindrical hinges, with frequent opening and closing, also wear out the inside of the hinge sleeve, which can also cause wobble and loosening. Therefore, a hinge that is adjustable and easy to install is needed to meet these requirements. Utility Model Content

[0003] The technical problem to be solved by the utility model is: in order to solve the problem of high installation precision and easy wear of hinges in the prior art, the utility model provides a novel bolt hinge.

[0004] The technical solution adopted by the utility model to solve its technical problems is: a new type of bolt hinge, including a movable bolt group, a connecting plate and a C-shaped plate; the movable bolt group includes a first bolt and a second bolt, the bolt head of the first bolt is connected to the middle of the C-shaped plate, the bolt column of the second bolt vertically passes through the bolt head of the first bolt and is connected to the C-shaped plate, and the connecting plate is connected to the bolt column of the first bolt.

[0005] Furthermore, the bolt head of the first bolt is annular, and the bolt column of the first bolt passes through the connecting plate and is fixed to the connecting plate by nuts on both sides. The two doors can be connected by connecting the bolt column to the connecting plate.

[0006] Furthermore, a first through hole and a second through hole are respectively provided at the upper and lower ends of the C-shaped plate, the first through hole and the second through hole are coaxial, and the apertures of the first through hole and the second through hole match the diameter of the bolt column of the second bolt.

[0007] Furthermore, a third through hole is provided on the connecting plate, and the third through hole is a waist-shaped hole. The bolt column of the first bolt passes through the waist-shaped hole, and the two ends are fixed by nuts, which can facilitate the adjustment of the position of the hinge. The waist-shaped hole can facilitate the bolt column of the first bolt to adjust the left and right positions of the connection.

[0008] Furthermore, the bolt head of the first bolt rotates around the bolt column of the second bolt, and the bolt head of the first bolt rotates around the bolt column of the second bolt to drive the connected door to rotate, thereby realizing the opening and closing of the door.

[0009] Furthermore, the material used for the movable bolt group is 304 stainless steel, which is not easy to rust, has a longer service life and is more beautiful.

[0010] Furthermore, the first bolt and the second bolt are both fully threaded bolts. The use of fully threaded bolts can be applicable to different types of doors and is convenient for adjustment.

[0019] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "horizontal", "top", "inside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can mean mechanical connection or electrical connection; it can mean direct connection or indirect connection through an intermediary. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0022] like Figure 1-4 As shown, a new type of bolt hinge includes a movable bolt group 1, a connecting plate 2 and a C-shaped plate 3; the movable bolt group 1 includes a first bolt 1-1 and a second bolt 1-2, the bolt head of the first bolt 1-1 is connected to the middle of the C-shaped plate 3, the bolt column of the second bolt 1-2 vertically passes through the bolt head of the first bolt 1-1 and is connected to the C-shaped plate 3, and the connecting plate 2 is connected to the bolt column of the first bolt 1-1.

[0023] The first bolt 1-1 has a circular bolt head. The bolt stud of the first bolt 1-1 passes through the connecting plate 2 and is fixed to the connecting plate 2 on both sides with nuts. The bolt stud is connected to the connecting plate 2 to connect the two doors. The C-shaped plate 3 has a first through hole 4 and a second through hole 5 at the upper and lower ends, respectively. The first through hole 4 and the second through hole 5 are coaxial, and the diameters of the first through hole 4 and the second through hole 5 match the diameters of the bolt stud of the second bolt 1-2.
