Description

Technical Field

[0001] This utility model relates to the field of revolving door technology, and in particular to an eccentric door frame. Background Technology

[0002] With the continuous advancement of modern building technology, the market has placed higher demands on the design and functionality of doors. Eccentric door frames, as a specially designed door frame structure, have been widely used in commercial buildings, residential projects, and public facilities due to their unique aesthetic style and practicality. Eccentric door frames typically achieve the rotational opening of the door leaf relative to the door frame through a combination of a top pivot (or upper pivot) and a bottom pivot.

[0003] However, in practical applications, it has been found that most existing traditional hinges on the market rely solely on simple fixing plates to connect to the door leaf. This is insufficient for door leaves with embedded glass or other heavy materials. Especially when the door leaf contains a large area of ​​glass, traditional hinges are prone to deformation or even breakage and detachment. Utility Model Content

[0004] To address the problems mentioned above in the background art, this utility model provides an eccentric door frame.

[0005] The solution adopted by this utility model to solve its technical problem is: an eccentric door frame, including a door frame, door leaf, top pivot, and bottom pivot. The door leaf is installed inside the door frame, and the door leaf includes a top corner door leaf and a bottom corner door leaf. The top pivot is installed on the top corner door leaf to support the upper part of the door leaf and allow the door leaf to rotate relative to the door frame. The bottom pivot is installed on the bottom corner door leaf to cooperate with the top pivot to allow the door leaf to rotate relative to the door frame. The top pivot includes a bushing seat disposed in the door frame and a load-bearing seat fixedly embedded in the top corner door leaf to enhance the load-bearing capacity. The load-bearing seat is provided with a shaft core extending upward and inserted into the bushing seat. The shaft core can rotate relative to the bushing seat around its axis.

[0006] By adopting the above technical solution, the contact area between the door panel and the load-bearing base is increased by adding a load-bearing base, so as to evenly distribute the weight of the lower door panel on the load-bearing base fixedly embedded in the door panel, thereby reducing the phenomenon of local stress concentration and effectively preventing the door panel and the top hinge from sinking and detaching due to excessive weight of the lower door panel.

[0007] Furthermore, the top corner door leaf includes a first frame and a second frame, and a receiving cavity for accommodating a load-bearing seat is formed between the first frame and the second frame. Multiple fasteners for fastening to the first frame and the second frame are arranged on both sides of the load-bearing seat.

[0008] By adopting the above technical solution, multiple fasteners are installed on both sides of the load-bearing base, which are fixedly connected to the first frame and the second frame on both sides, respectively, to ensure that the connection between the load-bearing base and the door leaf is more secure.

[0009] Furthermore, the top of the load-bearing base is also provided with an integrally formed fixing plate, which is fixedly installed on the top corner door leaf.

[0010] By adopting the above technical solutions, the area of ​​the top hinge and the door leaf is increased, ensuring that the load-bearing seat is not displaced by external forces.

[0011] Furthermore, each corner of the fixing plate is provided with countersunk screw holes, which are used to fix the fixing plate to the top corner door leaf by setting bolts in the countersunk screw holes.

[0012] By adopting the above technical solution, it can be ensured that the fixing plate can be firmly installed on the top corner door leaf. Furthermore, the bolt heads can be inserted into the countersunk screw holes, avoiding any interference with the rotation and opening / closing of the door leaf.

[0013] Furthermore, a thermal expansion sealing strip is fixedly installed between the door leaf and the door frame.

[0014] By adopting the above technical solutions, the sealing performance can be improved.

[0015] In summary, the beneficial effects of this utility model are as follows: By adding a top bearing support and embedding it inside the door leaf and tightly fixing it to the top corner area of ​​the door leaf, the contact area between the support and the door leaf is increased. This allows the weight transmitted from the inner door panel to be evenly distributed across the entire support and diffused towards the side frames, thereby reducing local stress concentration and improving the load-bearing capacity of the top bearing and the stability of the overall structure.

[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] like Figures 1 to 4 As shown, an eccentric door frame includes a door frame 1, a door leaf, a top pivot 3, and a bottom pivot 4. The door leaf is installed inside the door frame 1, and a door panel is provided inside the door leaf. The door leaf mainly includes a top corner door leaf 21 and a bottom corner door leaf 22. The top pivot 3 is installed inside the top corner door leaf 21, which is responsible for supporting the upper end of the door leaf and allowing the door leaf to rotate relative to the door frame 1. The bottom pivot 4 is installed inside the bottom corner door leaf 22 to cooperate with the top pivot 3 so that the door leaf can rotate relative to the door frame 1. In this embodiment, the top pivot 3 includes a bushing seat 31 set in the door frame 1 and a load-bearing seat 32 fixedly embedded in the top corner door leaf 21 to enhance the load-bearing capacity. The load-bearing seat 32 is provided with a shaft core 321 that extends upward and is inserted into the bushing seat 31, and the shaft core 321 can rotate relative to the bushing seat 31 around its axis.

[0026] The top pivot 3 in this embodiment mainly comprises two parts: a bushing seat 31 disposed within the door frame 1; and a load-bearing seat 32 fixedly embedded within the top corner door leaf 21. The load-bearing seat 32 has an upwardly extending shaft core 321 inserted into the bushing seat 31, which can rotate relative to the bushing seat 31 around its axis. When the door leaf rotates, the shaft core 321 rotates within the bushing seat 31, allowing the door leaf to rotate smoothly within the door frame 1 without generating additional resistance. And as... Figure 2 As shown, a load-bearing base 32, made of high-strength material and embedded in the door leaf, is added. Grooves on both sides allow the door leaf structure to be embedded and tightly integrated with the top corner area of ​​the door leaf. This not only increases the contact area between the load-bearing base 32 and the door leaf but also more effectively disperses the weight transmitted from the inner door panel. By increasing the contact area, the force can be more evenly distributed across the entire load-bearing base 32, thereby reducing localized stress concentration and enhancing the overall load-bearing capacity of the system.

[0027] like Figure 2 As shown, the corner door leaf 21 in this embodiment specifically includes a first frame 211 and a second frame 212. A receiving cavity 213 for accommodating the load-bearing seat 32 is formed between the first frame 211 and the second frame 212. Multiple fasteners 322 are arranged on both sides of the load-bearing seat 32 for respectively securing it to the first frame 211 and the second frame 212. The corner door leaf 21 is composed of the first frame 211 and the second frame 212, forming a receiving cavity 213 for installing the load-bearing seat 32. Multiple fastening bolts are provided on both sides of the load-bearing seat 32 to securely connect it to the first frame 211 and the second frame 212 on both sides, ensuring a more secure connection between the load-bearing seat 32 and the door leaf. This multi-point fixing design effectively distributes the pressure borne by the load-bearing seat 32, thereby improving the stability of the overall structure.

[0028] like Figure 2 and Figure 4 As shown, the top of the load-bearing base 32 in this embodiment is also provided with an integrally formed fixing plate 33, which is fixedly installed on the top of the corner door leaf 21. The integrally formed fixing plate 33 at the top of the load-bearing base 32 forms a whole with the load-bearing base 32 itself. The fixing plate 33 is directly fixedly installed on the top of the corner door leaf 21 and is tightly connected to the first frame 211 and the second frame 212 of the corner door leaf 21 by fasteners 322, thereby increasing the area between the top pivot 3 and the door leaf and ensuring that the load-bearing base 32 is not displaced due to external forces.

[0029] like Figure 4As shown, each corner of the fixing plate 33 in this embodiment is provided with countersunk screw holes 331, which are used to fix the fixing plate 33 to the top corner door leaf 21 by bolts installed in the countersunk screw holes 331. The countersunk screw holes 331 at each corner of the fixing plate 33 are used in conjunction with the bolts to ensure that the fixing plate 33 can be firmly installed on the top corner door leaf 21. In addition, the countersunk screw holes 331 allow the bolt head to be fully embedded in the fixing plate 33, avoiding the bolt head protruding and affecting the flatness of the door leaf, thus affecting the rotation and opening of the door leaf.

[0030] like Figure 3 As shown, a thermal expansion sealing strip 5 is fixedly installed between the door leaf and the door frame 1 in this embodiment. It can fill the gap between the door leaf and the door frame 1, thereby improving the airtightness of the door.

[0031] In summary, the beneficial effects of this embodiment are as follows: By adding a load-bearing seat 32 to the top of the door leaf and embedding it tightly in the top corner area of ​​the door leaf, the contact area between the load-bearing seat 32 and the door leaf is increased. The weight transmitted from the inner door panel can be evenly distributed to the entire load-bearing seat 32 and diffused to the side frames to reduce local stress concentration. A fixing plate 33 is integrally formed above the load-bearing seat 32, which can be tightly connected to the top of the first frame 211 and the second frame 212 by bolts, further preventing the top of the top of the door leaf from shifting or deforming due to force, thereby improving the load-bearing capacity of the top of the door leaf and the stability of the overall structure.

[0032] The embodiments described above are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and modifications made by those skilled in the art based on this utility model shall fall within the scope of protection of this utility model.
