Description

Technical Field

[0001] This utility model belongs to the field of door hinges, and in particular relates to a large door hinge with a bearing. Background Technology

[0002] In scenarios involving large doors, such as industrial plants, warehouses, and large venues, existing door locks present numerous problems. Traditional door locks typically have simple structures and lack effective measures to cope with the significant friction and impact forces generated by the frequent opening and closing of large doors. This leads to severe wear and tear after prolonged use, not only shortening the lock's lifespan but also potentially affecting the door's normal opening and closing function, increasing maintenance costs and safety hazards. Furthermore, when installing and adapting ordinary door locks to large doors, the large size and weight of these doors demand higher installation precision and stability. Existing door locks are inadequate in terms of installation convenience and compatibility with large doors, failing to meet practical needs. Simultaneously, traditional door locks require considerable operating force due to the lack of effective buffering and assist structures, which is extremely inconvenient for users, especially in work environments requiring frequent opening and closing of large doors, increasing the workload of workers. Therefore, developing a bearing-integrated large door hinge that can solve the above problems is of significant practical importance. Utility Model Content

[0003] The purpose of this utility model is to provide a large door hinge with a bearing, aiming to solve the problems existing in the background art. To achieve this purpose, the technical solution adopted by this utility model is:

[0004] A large door hinge with bearings includes a fixed component, a movable blade, screws and nuts. The movable blade is movably connected to the fixed component by the screws and nuts, and the fixed component has bearings inside.

[0005] Preferably, the movable blade is provided with reinforcing ribs, and the reinforcing ribs are integrated with the movable blade.

[0006] Preferably, the fastener is provided with a plurality of first mounting holes, which are used to install the fastener on the wall.

[0007] Preferably, the movable blade is provided with a plurality of second mounting holes, which are used to install the movable blade on the door.

[0008] The beneficial effects of this utility model are:

[0009] Extended service life: This invention incorporates a bearing within the fixing component. During the opening and closing of large doors, the relative rotation between the moving blade and the fixing component is achieved through the bearing. The rolling friction of the bearing is far less than that of traditional sliding friction, greatly reducing wear between the moving blade and the fixing component, thereby significantly extending the service life of the door hinge and reducing the frequency and cost of replacing the door lock.

[0010] Improved ease of operation: Thanks to the bearings, the rotation of the moving blades is smoother, significantly reducing the force required by the user when opening and closing the door. This effectively reduces the workload of staff and improves work efficiency in scenarios involving frequent operation of large doors.

[0011] Enhanced installation stability: Multiple primary mounting holes on the fastener allow for secure installation onto the wall using multiple screws; multiple secondary mounting holes on the movable blade ensure stable installation on the door. This multi-mounting-hole design increases the connection points between the lock and the door / wall, distributing the stress and making the lock more stable when bearing the weight of large doors and the impact of opening and closing, preventing loosening or displacement, and ensuring the normal use and security of the door.

[0012] Enhanced structural strength: The integrated reinforcing ribs on the moving blades enhance their structural strength. Large doors generate significant stress during opening and closing; the reinforcing ribs effectively disperse this stress, preventing deformation of the moving blades that could affect the normal function of the lock, thus further improving the reliability and durability of the lock.

The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0019] It should be noted that when an element is referred to as being "fixed to" another element, it can be directly on the other element or there may be an intermediate element. When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element present. Conversely, when an element is referred to as being "directly on" another element, there is no intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations. The terms "upper end," "lower end," "left side," "right side," "front end," "rear end," and similar expressions used herein refer to the positional relationship with reference to the accompanying drawings.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-3 As shown, this utility model embodiment provides a large door hinge with a bearing, including a fixing part 1, a movable blade 2, a screw 3 and a nut 4. The movable blade 2 is movably connected to the fixing part 1 by the screw 3 and the nut 4. The fixing part 1 is provided with a bearing 5 inside.

[0023] In this embodiment, the movable blade 2 is provided with a reinforcing rib 6, and the reinforcing rib 6 is integrated with the movable blade 2.

[0024] In this embodiment, the fastener 1 is provided with a plurality of first mounting holes 7, which are used to install the fastener 1 on the wall.

[0025] In this embodiment, the movable blade 2 is provided with a plurality of second mounting holes 8, which are used to install the movable blade 2 on the door.

[0026] Working principle:

[0027] When a large door needs to be opened or closed, the movement of the door drives the movement of movable blades mounted on it. Since the movable blades are movably connected to a fixed component via screws and nuts, and the fixed component contains bearings, the rotation of the movable blades is achieved through these bearings. In this process, the bearings convert the sliding friction between the movable blades and the fixed component into rolling friction, greatly reducing frictional force. For example, when the door rotates around its hinge, the movable blades rotate relative to the fixed component as the door rotates. The balls or rollers inside the bearings roll between the inner and outer rings, making the rotation of the movable blades smoother and reducing wear.

[0028] Meanwhile, the reinforcing ribs on the movable blades enhance their resistance to deformation during door opening and closing. Large doors generate significant stress during movement; the reinforcing ribs disperse this stress, ensuring the movable blades maintain structural stability even under frequent stress. The first mounting hole on the fastener and the second mounting hole on the movable blades securely mount the door lock to the wall and door with screws. These multiple mounting holes distribute the force on the door lock, ensuring stable operation during door opening and closing without loosening or displacement, thus enabling the normal opening and closing function of the large door.

[0029] The above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present utility model. Therefore, all equivalent technical solutions also fall within the scope of the present utility model. The patent protection scope of the present utility model should be defined by the claims.
