Description

Technical Field

[0001] This utility model relates to the field of door bodies, and in particular to a quick positioning device for door frames and the door frames in which it is applied. Background Technology

[0002] Currently, workers need to stabilize the upper frame of the door glass, place the upper frame on top of the door frame, and finally tighten the screws to fix the two together. This method is quite difficult to operate, requiring perfect alignment and making it difficult to insert the screwdriver, thus making it difficult to improve efficiency. Utility Model Content

[0003] To address the aforementioned issues, this technical solution provides a quick positioning device for door frames and a door frame in which it is applied. This design enables rapid positioning and assembly, significantly improving assembly efficiency.

[0004] To achieve the above objectives, the technical solution is as follows:

[0005] A quick positioning device for a door frame includes an upper shaft seat disposed on an upper rail and a fixed seat disposed on a folding upper frame, and further includes a shaft body slidably connected to the upper shaft seat and capable of extending into the fixed seat. The upper shaft seat is also provided with a drive assembly for driving the shaft body to move.

[0006] In some embodiments, the drive assembly includes a hinge block disposed on the upper shaft seat, a drive component located on one side of the hinge block and movable up and down along the upper shaft seat, and a lever, wherein one end of the lever is connected to the drive component, the lever body is hinged to the hinge block, and the other end is connected to the shaft.

[0007] In some embodiments, the drive component is threadedly connected to the upper shaft seat.

[0008] In some embodiments, the drive component has an annular cavity, and the end of the lever is arc-shaped and extends into the annular cavity.

[0009] In some embodiments, the upper shaft seat is provided with a limiting part for the shaft to move, the upper shaft seat is also provided with a limiting groove, and the shaft is provided with a hole for the lever to be inserted.

[0010] In some embodiments, the mounting base is provided with a bushing.

[0011] This application also provides a door frame, including a fixed door frame and a folding door frame that are hinged to each other. The fixed door frame includes an upper rail, an upper frame, and a quick positioning device for a door frame as described above, and also includes a lower base plate located below the quick positioning device.

[0012] In some embodiments, the lower base plate is provided with a lower shaft seat, and the lower base plate is also provided with an adjusting screw that can move the lower shaft seat.

[0013] The beneficial effects of this application are:

[0014] This application achieves rapid positioning and assembly by driving the shaft to move downward and insert into the fixed seat through a drive component, replacing the original screw assembly. This results in higher assembly efficiency, significantly reduced operation difficulty, more convenient installation and adjustment, and simpler and faster disassembly. Attached Figure Description

[0015] To more clearly illustrate the technical solutions in the embodiments of this utility model, the accompanying drawings used in the description of the embodiments will be briefly introduced below.

[0016] Figure 1 This is a structural schematic diagram of an embodiment of the present utility model;

[0017] Figure 2 This is an exploded view of an embodiment of the present utility model (partial structures omitted);

[0018] Figure 3 yes Figure 1 Enlarged view of point A. Detailed Implementation

[0019] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] Please refer to Figure 1-3 As shown, a quick positioning device for a door frame includes an upper shaft seat 2 disposed on an upper rail 1 and a fixed seat 4 disposed on an upper frame 3. It also includes a shaft 5 slidably connected to the upper shaft seat 2 and capable of extending into the fixed seat 4. The upper shaft seat 2 is further provided with a drive assembly for driving the shaft 5 to move.

[0021] This application achieves rapid positioning and assembly by driving the shaft to move downward and insert into the fixed seat through a drive component, replacing the original screw assembly, which improves assembly efficiency and greatly reduces the difficulty of operation.

[0022] As a preferred embodiment of the drive assembly, the drive assembly includes a hinge block 6 disposed on the upper shaft seat 2, a drive component 61 located on one side of the hinge 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 drive component 61, the lever body is hinged to the hinge block 6, and the other end is connected to the shaft body 5.

[0023] refer to Figure 2This application uses the lever principle. If the drive component is moved upward, so that one side of the lever rises and the other side sinks, the shaft will move towards the fixing hole of the fixing seat. Conversely, it will move away from the fixing hole. In this way, not only can quick assembly be achieved, but also quick disassembly. The length of the lever on both sides of the hinge seat is different, with the side closer to the shaft being significantly longer. This is to utilize the force-saving lever principle, making disassembly and assembly more effortless.

[0024] In a preferred embodiment of the operation, the drive component 61 is threadedly connected to the upper shaft seat 2, and is driven to move up and down by the helical rotation drive component.

[0025] Preferably, the drive 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 drive method is to reduce production time, and the shape design reduces friction, so that the drive component can rotate better and the lever can be driven to move at the same time.

[0026] Preferably, the upper shaft seat 2 is provided with a limiting part 64 for the shaft body 5 to move, 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 lever 62 to be inserted. First, the limiting part limits the movement of the shaft body for precise positioning. Second, the limiting groove prevents the lever from overturning. Finally, after the end of the lever is inserted into the hole of the shaft body, it can drive the shaft body to move up and down.

[0027] Preferably, the fixing seat 4 is provided with a bushing 7, which is used to provide a certain friction between it and the shaft to prevent loosening.

[0028] This application also provides a door frame, including a fixed door frame 8 and a folding door frame 9 that are hinged to each other. The fixed door frame includes an upper rail 1, an upper frame 3, and a quick positioning device for a door frame as described above. It also has a lower base plate 10 located below the quick positioning device.

[0029] Specifically, the upper rail is fixed to the door opening, then the door frame is positioned and fixed, 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, thus assembling the door glass.

[0030] In the above embodiment, the lower base plate 10 is provided with a lower shaft seat 101, and the lower base plate 10 is also provided with an adjusting screw 102 that can move the lower shaft seat 101. Since the lower shaft seat may not be perfectly aligned with the door glass, this application provides adjusting screws in two directions. By rotating the adjusting screws, the lower shaft seat can be adjusted in different directions in the two axial directions to align with the door glass.

[0031] The above description is only a preferred embodiment of this application and is not intended to limit the scope of implementation of this application. Any other embodiments whose principles and basic structures are the same as or similar to those of this application are within the protection scope of this application.
