Description

Technical Field

[0001] The utility model relates to the technical field of hardware accessories, in particular to a ceiling and door shaft which is easy to assemble. Background Art

[0002] The top and bottom hinges, also known as the top and bottom door shafts, are commonly used on partition doors. For example, the glass partition doors of shower rooms are mostly installed with top and bottom door shafts to achieve relative rotation between the door body and the door frame. The top and bottom door shafts are upper and lower structures, respectively installed on the top and bottom of the door body. They are positioned through the axis and bear the shear force and gravity of the door body respectively. The hinges of traditional top and bottom door shafts have a small bearing capacity, and the connection between the hinges and the door and door frame is complicated. The construction and subsequent maintenance and disassembly are inconvenient. After installation, the hinges are exposed to the outside, and the overall aesthetics are low. In addition, the existing top and bottom door shafts lack a limiting mechanism. After the door body is installed, the door opening angle is not restricted. In particular, if the glass partition door is opened with too much force and causes a collision, it is very easy to cause the glass to shatter, posing a safety hazard. If a limiter is installed for the door body alone, the cost of use is increased. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a new type of limited door shaft that is easy to install and maintain. After installation, the overall aesthetics are improved, and the door shaft has its own limited structure, making it safer and more reliable to use.

[0004] The utility model is realized through the following technical solution: a ceiling door shaft that is easy to assemble, including a fixed part connected to the door frame and a movable part connected to the door body, the fixed part and the movable part are rotatably connected through a rotating shaft, and also includes a clamping part, and the fixed part is clamped to the door frame through the clamping part.

[0005] This solution's fixings connect to the door frame via snap-fits, eliminating the need for bolts. This makes assembly and maintenance easier, and the connection between the fixings and the door frame more stable, making it easier to maintain and disassemble later. The snap-fit ​​method also avoids bolt leakage and long-term rusting associated with existing bolt connections, extending the lifespan of the door hinge and improving the overall aesthetics of the door hinge after installation.

[0006] As an optimization, the engaging member includes a connecting seat connected to the fixing member and a clamping seat clamped to the door frame, and the connecting seat and the clamping seat are connected. In this optimization solution, the engaging member is clamped to the door frame through the clamping seat and connected to the fixing member through the connecting seat, thereby realizing the clamping connection between the fixing member and the door frame.

[0007] As an optimization, the base includes a vertically extending card plate, with an external boss on the side of the card plate near the connecting base. The end of the external boss, away from the card plate, is fixedly connected to the connecting base. The door frame is provided with a slot adapted for the base. The base of this optimization solution has a T-shaped structure, which facilitates the connection with the door frame. The engagement of the card plate ensures good stability after the connection.

[0008] As an optimization, the side end of the fixing member is provided with a recessed groove that engages with the connecting seat, and the connecting seat is embedded in the recessed groove. This optimization solution makes the fixing member and the connecting seat form a whole by embedding the connecting seat in the recessed groove of the fixing member, improving the overall aesthetics, and enhancing the connection strength between the fixing member and the connecting seat, making the connection between the fixing member and the connecting seat more convenient.

[0009] As an optimization, the fixing member and the engaging member are fixed by bolt connection. This optimization solution is convenient for the installation of the fixing member. When in use, the engaging member can be engaged with the door frame first and then the fixing member can be installed, which is convenient for assembly and disassembly.

[0010] As an optimization, the movable member is clamped and fixed to the door body. In this optimization solution, the movable member is clamped and fixed to the door body, making the connection between the movable member and the door body more convenient and easy to install.

[0011] As an optimization, the movable member includes a base plate, a fixed plate, and a movable plate. The fixed plate is fixed to the base plate, and the movable and fixed plates are located on either side of the door body and connected by bolts. This optimized solution uses the movable and fixed plates to clamp the door body. Because the movable plate is free, it can clamp doors of varying thicknesses, and the clamping is more secure and stable.

[0012] As an optimization, a plurality of gaskets are provided between the movable splint and the fixed splint. This optimization solution can provide a good buffering effect by placing gaskets between the door body and the splint, thereby preventing the movable parts from damaging the door body.

[0013] As an optimization, the rotating shaft and the movable part are fixedly connected, the rotating shaft is provided with an outwardly protruding limiting post, and the fixed part is provided with an assembly hole for the rotating shaft to be inserted, and the assembly hole is provided with a limiting groove that cooperates with the limiting post. In this optimized solution, the movable part rotates within the assembly hole of the fixed part via the rotating shaft, and the limiting groove in the assembly hole cooperates with the limiting post of the rotating shaft to limit the rotation angle of the rotating shaft, thereby controlling the opening and closing angle of the door body, preventing damage to the door body due to excessive opening force, and improving user safety.

[0014] As an optimization, the limiting groove is a fan-shaped groove, and the limiting column is a triangular prism. This optimization solution achieves limiting through the cooperation of the fan-shaped groove and the triangular prism. Since the end face of the triangular prism is flat, when rotating around the axis of rotation, the end face can fit with the end face of the fan-shaped groove, thereby improving the rotation angle and contact stability.

[0015] The beneficial effects of the present invention are as follows: the present invention is convenient and simple to install, the connection strength and stability between the door frame and the door body are higher, and the connection between the door frame and the door body is more beautiful and coordinated as a whole after installation. The fixing part is connected to the door frame by a snap-fit ​​part, and no bolts are required for fixing, which makes the connection between the fixing part and the door frame more convenient and stable. The movable part is connected and fixed by clamping the clamping groove and the door body, which makes the connection between the movable part and the door body more convenient and firm, and facilitates later maintenance and disassembly. The limiting groove in the assembly hole cooperates with the limiting column of the rotating shaft to limit the rotation angle of the rotating shaft, thereby controlling the opening angle of the door body and avoiding damage to the door body caused by excessive opening force, making it safer to use and saving costs.
