[0020] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0021] Please refer to Figure 1-3 As shown, a quick positioning device for a door frame includes an upper shaft seat 2 arranged on an upper rail 1 and a fixed seat 4 arranged on an upper frame 3, and also includes an axis body 5 slidably connected to the upper shaft seat 2 and capable of extending into the fixed seat 4. The upper shaft seat 2 is also provided with a driving component for driving the axis body 5 to move.

[0022] The present application uses a driving component to drive the shaft body downward and insert it into a fixing seat to achieve positioning and rapid transfer, replacing the original screw assembly, with higher assembly efficiency and greatly reduced operating difficulty.

[0023] As a preferred embodiment of the driving assembly, the driving assembly includes an articulated block 6 disposed on the upper shaft seat 2, a driving component 61 located on one side of the articulated block 6 and movable up and down along the upper shaft seat 2, and a lever 62, wherein one end of the lever 62 is connected to the driving component 61, the rod body is hinged to the articulated block 6, and the other end is connected to the shaft body 5;

[0024] refer to Figure 2 The present application adopts the lever principle. If the driving component is moved upward so that one side of the lever rises and the other side sinks, the shaft body is driven to move toward the fixing hole of the fixing seat, and vice versa. In this way, not only quick assembly but also quick disassembly can be achieved. The lengths of the levers on both sides of the hinge seat are different, and the side close to the shaft body is obviously longer. This is to utilize the principle of labor-saving lever, which saves more effort during disassembly and assembly.

[0025] As a preferred embodiment of the operation, the driving component 61 is threadedly connected to the upper shaft seat 2, and the driving component is driven to move up and down by spirally rotating the driving component.

[0026] Preferably, the driving component 61 is provided with an annular cavity 63, and the end of the lever 62 is arc-shaped and extends into the annular cavity 63. This contact driving method is intended to reduce production time, and the shape design reduces friction, so that the driving component can rotate better and drive the lever to move at the same time.

[0027] Preferably, the upper shaft seat 2 is provided with a limiting portion 64 for the movement of the shaft body 5, and the upper shaft seat 2 is also provided with a limiting groove 65. The shaft body 5 is provided with a hole for the insertion of the lever 62. Firstly, the limiting portion limits the movement of the shaft body for precise positioning, and secondly, the limiting groove is to prevent the lever from excessively flipping. Finally, the end of the lever can drive the shaft body to move up and down after being inserted into the hole of the shaft body.

[0028] Preferably, the fixing seat 4 is provided with a shaft sleeve 7, and the shaft sleeve is used to ensure a certain friction between the shaft and the shaft body to prevent loosening.

[0029] The present application also provides a door frame, comprising a fixed door frame 8 and a folding door frame 9 hinged to each other, wherein the fixed door frame comprises an upper rail 1, an upper frame 3 and a quick positioning device for a door frame as described above, and further comprises a lower base plate 10 located below the quick positioning device;

[0030] Specifically, the upper rail is fixed on the door opening, and then the door frame is positioned and assembled to fix it. The upper side of the door glass is fixed below the fixed door frame, and the lower side of the door glass is fixedly connected to the lower base plate, so that the door glass is assembled. In the above embodiment, a lower shaft seat 101 is provided in the lower base plate 10, and the lower base plate 10 is also provided with an adjustment screw 102 that can move the lower shaft seat 101. Since the lower shaft seat may not be completely aligned with the door glass, the present application provides adjustment screws in two directions. By rotating the adjustment screws, the lower shaft seat can be adjusted differently in two axial directions to align with the door glass.

[0031] Reference Figure 4-5 A new hinge for a door frame, comprising a first mounting portion 1001 for mounting on a folding door frame 9 and a second mounting portion 1002 for mounting on a fixed door frame 8, wherein a first flip portion 1003 is provided at the inner lower end of the first mounting portion 1001, a second flip portion 1004 is provided at the inner upper end of the second mounting portion 1002, a hinge shaft 1005 is provided between the first flip portion 1003 and the second flip portion 1004, a ring-shaped recess 1006 is provided around one side of the hinge shaft 1005, and a flip through hole 1007 for inserting a latch is provided on the first flip portion 1003 relative to the ring-shaped recess 1006;

[0032] Specifically, first, the first mounting part and the second mounting part are respectively placed in the corresponding door frames and fixed from the inside to ensure that the fixing structure is built-in, and then the first flipping part is sleeved on the lower end of the hinge shaft, and the second flipping part is sleeved on the upper end of the hinge shaft, and finally the pin is inserted into the annular recess through the flip through hole, which not only realizes the fixing function, but also can be flipped in the space of the annular recess, and the flipping angle is larger.

[0033] In this embodiment, the first mounting portion 1001 and the second mounting portion 1002 are in a plane and are arranged in parallel in the folding door frame 9 and the fixed door frame 8. This plane just fits the space in the frame and can play a certain load-bearing role, thereby increasing the stability of the hinge.

[0034] In this embodiment, a spacer 1008 is provided in the middle of the hinge shaft 1005 for positioning and installing the two flip parts.

[0035] In this embodiment, a plurality of fixing holes 1009 are provided on the first mounting portion 1001 and the second mounting portion 1002, and internal screws are provided for fixing the mounting.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
