Description

Technical Field

[0001] This utility model relates to the field of hinge door seat technology, and in particular to a multi-end load-bearing hinge door seat assembly. Background Technology

[0002] The hinge base assembly is a crucial component connecting the door leaf and the door frame, allowing the door leaf to open and close by rotation. A typical hinge base assembly consists of several key components: a hinge seat, a hinge arm, and a hinge pin, providing support and rotation. The hinge base assembly achieves the door leaf's support and rotation functions through the cooperation of the hinge seat, hinge arm, and hinge pin. Hinges are widely used in various door applications requiring rotational opening and closing, such as heavy-duty doors in warehouses and workshops, and are capable of withstanding significant weight and impact forces.

[0003] If a slightly excessive force is applied when opening the door, the existing door hinges may push the two hinges open to an excessive angle, which can easily cause irreversible damage to the connecting components and cause great inconvenience to the user.

[0004] An existing patent (publication number: CN211369933U) discloses a door hinge, which includes a hinge base and a hinge leaf. The hinge base has protrusions on both sides. The hinge leaf includes a hinge plate, a rotating component, and a connecting component. The rotating component is rotatably connected to the center of the protrusions, and the connecting component connects the hinge plate and the rotating component, with notches on both sides. When the door is open, a limiting post abuts against the hinge leaf's connecting component, restricting the hinge's rotation space and preventing damage from collision between the hinge leaf and the hinge base, thus improving the hinge's service life. When the door is closed, the hinge plate of the hinge leaf is flush with the bottom surface of the hinge base, and the rotating component and connecting component do not protrude beyond the hinge base, reducing the possibility of injury from collision.

[0005] To address the aforementioned issues, while existing patents offer solutions where the limiting post blocks the hinge's connecting parts, restricts the hinge's rotation space, prevents the hinge from colliding and damaging the door hinge seat, and improves the hinge's lifespan, the hinge structure's load-bearing capacity is poor. In particular, the hinge shaft of the door leaf is prone to deformation when subjected to shear loads, affecting its lifespan and potentially causing safety accidents. Summary of the Invention

[0006] The purpose of this utility model is to provide a multi-end load-bearing hinge door seat assembly. Through the connecting piece on the reinforcing rod, since the connecting piece is inserted inside the door hinge reinforcing seat, the shear load force borne by the hinge shaft is distributed to the door hinge reinforcing seat, thereby achieving the effect of multi-end load bearing and effectively reducing the deformation of the hinge shaft, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a multi-end load-bearing hinge door seat assembly, including a hinge fixing seat, two hinge reinforcing seats fixed to the side wall of the hinge fixing seat, the interior of the two hinge reinforcing seats being provided with a reinforcing mechanism for multi-end load-bearing of the hinge, and the outer wall of the two hinge reinforcing seats being provided with a fixing mechanism for fixing the hinge.

[0008] The reinforcing mechanism includes a hinge shaft, which is installed inside the two door hinge reinforcing seats respectively. Two L-shaped reinforcing rods are fixed to the outer wall of the hinge shaft. A connector is installed at the end of the reinforcing rod. A fixing bolt that is threadedly connected to the connector is installed on one side of the reinforcing rod. A guide groove opened on the inner surface of the door hinge reinforcing seat is slidably connected to the outer surface of the connector.

[0009] Preferably, the connector has two movable parts internally telescopically connected, and the side walls of both movable parts are fixed with springs.

[0010] Preferably, one side of each of the two movable parts is equipped with guide balls that match the inner wall of the guide groove.

[0011] Preferably, a hinge door seat plate is fixed to one side of the hinge shaft, and the hinge door seat plate has four fixing holes inside.

[0012] Preferably, four fixing screws are symmetrically installed inside the door hinge fixing seat.

[0013] Preferably, the fixing mechanism includes two fixed bearings, which are respectively embedded at both ends of the hinge shaft, and a connecting tube is fixed inside the fixed bearing.

[0014] Preferably, the inner wall of the door hinge reinforcement seat is inlaid with a sealing gasket, and the interior of the door hinge reinforcement seat is equipped with a limiting bolt that is threadedly connected to the connecting pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. Through the reinforcement mechanism and the connector on the reinforcement rod, the shear load on the hinge shaft is distributed to the hinge reinforcement seat because the connector is inserted inside the door hinge reinforcement seat, thereby achieving the effect of multi-end load bearing, effectively reducing the deformation of the hinge shaft. In addition, the spring in the connector will push the moving part to move vertically, so that the guide ball contacts the inner wall of the guide groove, thereby achieving the guiding function and ensuring the smoothness of the door opening.

[0017] 2. By tightening the limiting bolts on the door hinge reinforcement seat through the fixed mechanism, the end of the limiting bolts is connected to the connecting pipe, and the sealing gasket on the door hinge reinforcement seat can play a sealing role, thereby reducing the entry of external dust into the fixed bearing and improving the dustproof effect.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution:

[0027] Please see Figures 1 to 4A multi-end load-bearing hinge door seat assembly includes a hinge fixing seat 1, two hinge reinforcing seats 2 are fixed to the side wall of the hinge fixing seat 1, the interior of the two hinge reinforcing seats 2 is provided with a reinforcing mechanism for reinforcing the multi-end load of the hinge, and the outer wall of the two hinge reinforcing seats 2 is provided with a fixing mechanism for fixing the hinge.

[0028] The reinforcing mechanism includes a hinge shaft 3, which is installed inside the two door hinge reinforcing seats 2. Two L-shaped reinforcing rods 31 are fixed to the outer wall of the hinge shaft 3. Connectors 32 are installed at the ends of the reinforcing rods 31. A fixing bolt 33 that is threadedly connected to the connector 32 is installed on one side of the reinforcing rod 31. A guide groove 34 that is opened on the inner surface of the door hinge reinforcing seat 2 is slidably connected to the outer surface of the connector 32. Two movable parts 35 are telescopically connected inside the connector 32. Springs 36 are fixed to the side walls of the two movable parts 35. Guide balls 37 that match the inner wall of the guide groove 34 are installed on one side of the two movable parts 35. A hinge door seat plate 4 is fixed to one side of the hinge shaft 3. Four fixing holes 5 are opened inside the hinge door seat 1. Four fixing screws 6 are symmetrically installed inside the door hinge fixing seat 1.

[0029] By adopting the above technical solution, before using the multi-end load-bearing hinge door seat assembly, the hinge fixing seat 1 is first fixed on the door frame and fixed with fixing screws 6. Then, the hinge door seat plate 4 is connected to the door. Through the fixing holes 5 opened on the hinge door seat plate 4, bolts can be used to fix the hinge door seat plate 4. In use, the hinge door seat plate 4 and the hinge fixing seat 1 can rotate through the fixing bearing 7, thereby opening or closing the door. And through the connector 32 on the reinforcing rod 31, since the connector 32 is inserted inside the door hinge reinforcing seat 2, the shear load force borne by the hinge shaft 3 is distributed to the door hinge reinforcing seat 2, thereby achieving the effect of multi-end load bearing and effectively reducing the deformation of the hinge shaft 3. The spring 36 set in the connector 32 will push the moving part 35 to move vertically, so that the guide ball 37 contacts the inner wall of the guide groove 34, thereby achieving the guiding function. By unscrewing the fixing bolts 33, the connector 32 can be disassembled, which facilitates individual replacement.

[0030] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, the fixing mechanism includes two fixed bearings 7, which are respectively embedded at both ends of the hinge shaft 3. A connecting pipe 71 is fixed inside the fixed bearing 7. A sealing gasket 72 is embedded in the inner wall of the door hinge reinforcing seat 2. A limiting bolt 73 that is threadedly connected to the connecting pipe 71 is installed inside the door hinge reinforcing seat 2.

[0031] By adopting the above technical solution, the hinge shaft 3 on the hinge door seat plate 4 is aligned with the interior of the two door hinge reinforcing seats 2, and the connecting piece 32 is inserted into the guide groove 34 in the door hinge reinforcing seat 2. After the hinge shaft 3 and the two door hinge reinforcing seats 2 are aligned, the limiting bolt 73 on the door hinge reinforcing seat 2 is tightened, so that the end of the limiting bolt 73 is connected to the connecting pipe 71, and the sealing gasket 72 provided on the door hinge reinforcing seat 2 can play a sealing role, thereby reducing the situation of external dust entering the fixed bearing 7 and improving the dustproof effect.

[0032] Working principle: Align the hinge shaft 3 on the hinge base plate 4 with the interior of the two hinge reinforcement seats 2, and insert the connector 32 into the guide groove 34 inside the hinge reinforcement seat 2. After the hinge shaft 3 and the two hinge reinforcement seats 2 are aligned, tighten the limiting bolt 73 on the hinge reinforcement seat 2, so that the end of the limiting bolt 73 is connected to the connecting pipe 71. The sealing gasket 72 on the hinge reinforcement seat 2 can play a sealing role. The hinge base plate 4 and the hinge fixing seat 1 can rotate through the fixed bearing 7, thereby opening or closing the door. Through the connector 32 on the reinforcing rod 31, since the connector 32 is inserted inside the hinge reinforcement seat 2, the shear load force borne by the hinge shaft 3 will be distributed to the hinge reinforcement seat 2, thereby achieving the effect of multi-end bearing and effectively reducing the deformation of the hinge shaft 3. The spring 36 inside the connector 32 will push the moving part 35 to move vertically, so that the guide ball 37 contacts the inner wall of the guide groove 34, thereby achieving the guiding function.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
