Description

Technical Field

[0001] This utility model relates to the technical field of revolving door accessories, specifically to a vertically adjustable rotating mechanism for revolving doors and a revolving door. Background Technology

[0002] In commercial and public spaces such as retail stores, hotels, and restaurants, revolving doors serve as entrance facilities, combining efficient two-way passage for people with spatial aesthetics. Their 360-degree rotation enhances the practicality and design of the space. Traditional revolving door installations generally employ a fixed pivot structure, which rigidly connects the door directly to the wall, relying on the pivot for rotation. However, during construction, wall height deviations or structural deformations often occur, making precise alignment between the door frame and the wall difficult. Existing pivot systems lack vertical adjustment capabilities, requiring repeated disassembly and adjustment during installation to accommodate height differences, significantly extending the construction period and increasing labor costs. Furthermore, after the building is put into use, foundation settlement or material aging can easily cause height misalignment between the door and the wall, resulting in increased rotational resistance, operational stagnation, and even structural damage, seriously affecting the long-term stability of the revolving door and user safety. This lack of height adjustment makes the installation process rigid, unable to flexibly respond to dynamic changes in actual projects, and restricts the adaptability and maintenance efficiency of the revolving door system. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a vertically adjustable rotating mechanism and a revolving door for revolving doors, so as to solve the problem that the existing revolving doors have poor flexibility due to the inability to flexibly adjust their installation height during the installation process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: In a first aspect, this application provides a vertically adjustable rotating mechanism for a revolving door, including a door frame connector, a door leaf connector, a connecting bolt, a first positioning nut, and a second positioning nut. The door frame connector has a first connecting hole, and the door leaf connector has a second connecting hole. The threaded end of the connecting bolt passes vertically through the first connecting hole and the second connecting hole in sequence and extends downward from the second connecting hole. A locking nut is provided on the bottom end surface of the door leaf connector, which is concentrically arranged with the second connecting hole. The threaded end of the connecting bolt is fixed to the locking nut, and the head of the connecting bolt is located at the upper end of the first connecting hole. The first positioning nut is fixedly installed on the connecting bolt at a position adjacent to the threaded end of the connecting bolt. The first positioning nut is used to press and fix the door leaf connector to the locking nut. The second positioning nut is fixedly installed on the connecting bolt and fits against the first positioning nut. The second positioning nut is used to press and fit the first positioning nut against the door leaf connector. The portion of the connecting bolt adjacent to the head is rotatably installed in the first connecting hole, and the connecting bolt can move up and down relative to the first connecting hole.

[0005] Furthermore, a smooth mounting portion is provided on the connecting bolt near the threaded end, and a bearing is mounted on the mounting portion. The bearing is installed in the first connecting hole, and the mounting portion can slide up and down relative to the bearing.

[0006] Furthermore, the door frame connector includes a flat lower connecting part and an upper connecting part extending vertically upward from the inner side of the lower connecting part. The upper connecting part and the lower connecting part form an "L" shaped external structure. The first connecting hole is opened on the lower connecting part, and the upper connecting part is provided with upper waist-shaped mounting holes around its perimeter for fixing the door frame connector to the door frame.

[0007] Furthermore, the second connecting hole is located at the center of the door panel connector, and the door panel connector is provided with waist-shaped mounting holes around its perimeter for fixing it to the top of the door panel.

[0008] Secondly, embodiments of this application also provide a revolving door, including a revolving door body and a vertically adjustable rotating mechanism for the revolving door as described above, wherein the vertically adjustable rotating mechanism is installed at the top of the revolving door body.

[0009] The beneficial effects of this utility model are as follows: By adopting the aforementioned vertically adjustable rotating mechanism and rotating door for revolving doors, and through the rotation and sliding installation design of the connecting bolts, the vertical height adjustment function is realized, effectively compensating for the influence of wall height deviation or structural deformation.

Detailed Implementation

[0016] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] Traditionally, revolving doors used in commercial or public spaces such as retail stores, showrooms, hotels, and restaurants typically achieve their rotation on the wall by installing a hinge. However, in actual installation, the hinge in existing technology cannot provide effective adjustment functionality to facilitate height adjustment, resulting in poor installation flexibility and difficulty in adapting to different installation environments and height requirements.

[0018] Reference Figures 1 to 5As shown, this application proposes a vertically adjustable rotating mechanism 10 for a revolving door. The vertically adjustable rotating mechanism 10 includes a door frame connector 100, a door leaf connector 200, a connecting bolt 300, a first positioning nut 400, and a second positioning nut 500. The door frame connector 100 has a first connecting hole 103, and the door leaf connector 200 has a second connecting hole 201. The threaded end 302 of the connecting bolt 300 passes vertically through the first connecting hole 103 and the second connecting hole 201, and extends downward from the second connecting hole 201. A locking nut, concentrically arranged with the second connecting hole 201, is provided on the bottom surface of the door leaf connector 200, and the threaded end 302 of the connecting bolt 300 is fixed within the locking nut. Understandably, the locking nut can be fixed to the bottom surface of the door panel connector 200 by welding. This way, when the threaded end 302 of the connecting bolt 300 extends downwards from the second connecting hole 201, the threaded end 302 is fixed inside the locking nut. The head 301 of the connecting bolt 300 is located at the upper end of the first connecting hole 103. The first positioning nut 400 is fixedly installed on the connecting bolt 300 near the threaded end 302 of the connecting bolt 300. The second positioning nut 500 is fixedly installed on the connecting bolt 300, and simultaneously, the second positioning nut 500 is in contact with the first positioning nut 400. The first positioning nut 400 is used to fix and press the door leaf connector 200 onto the locking nut, and the second positioning nut 500 is used to press the first positioning nut 400 tightly against the door leaf connector 200. This ensures the connection and fixation between the door leaf connector 200 and the threaded end 302 of the connecting bolt 300, allowing the door leaf connector 200 to rotate synchronously with the connecting bolt 300. The first positioning nut 400 and the second positioning nut 500 provide a double fixing effect, preventing relative rotation between the door leaf connector 200 and the connecting bolt 300. The connecting bolt 300 is rotatably installed in the first connecting hole 103 near the head 301. This allows the connecting bolt 300 to rotate relative to the stationary door frame connector 100, and simultaneously allows it to move vertically relative to the first connecting hole 103. When adjusting the installation height of the connecting bolt 300, it can be adjusted by rotating it in both directions relative to the first connecting hole 103. Once the installation position of the connecting bolt 300 is adjusted to the appropriate height, the first positioning nut 400 and the second positioning nut 500 are then tightened. This mechanism aims to solve the problem of difficult installation height adjustment in existing revolving doors while ensuring smooth rotation.

[0019] The vertically adjustable rotating mechanism in this embodiment comprises a door frame connector 100, a door leaf connector 200, a connecting bolt 300, a first positioning nut 400, and a second positioning nut 500. The door frame connector 100 and the door leaf connector 200 can be made of metal materials (e.g., steel, aluminum alloy) through processes such as stamping, casting, or welding to provide structural strength. The connecting bolt 300 can be a standard bolt, with its threaded end 302 and head 301 matching the dimensions of the connecting hole. The first positioning nut 400 and the second positioning nut 500 can be standard hexagonal nuts or flange nuts.

[0020] The door frame connector 100 has a first connecting hole 103. This first connecting hole 103 can be a circular through hole, formed by drilling or laser cutting. Its diameter can be slightly larger than the diameter of the shank of the connecting bolt 300 to allow the connecting bolt 300 to pass through smoothly. For example, the first connecting hole 103 can be designed as a simple circular hole through which the connecting bolt 300 passes directly.

[0021] The door panel connector 200 has a second connecting hole 201. This second connecting hole 201 can also be a circular through hole, formed by drilling or punching. Its diameter can match the diameter of the shank of the connecting bolt 300, or be slightly larger than the diameter of the shank of the connecting bolt 300. For example, the second connecting hole 201 can be designed as a circular hole with a diameter similar to that of the shank of the connecting bolt 300.

[0022] The threaded end 302 of the connecting bolt 300 passes vertically through the first connecting hole 103 and the second connecting hole 201 in sequence, and extends vertically downward from the second connecting hole 201. During installation, the connecting bolt 300 can pass vertically downward from above the first connecting hole 103 of the door frame connector 100, and then continue downward through the second connecting hole 201 on the door leaf connector 200. Its threaded end 302 extends to the bottom of the door leaf connector 200 and is fixedly installed in the lock nut 700 by thread engagement.

[0023] During the process of the connecting bolt 300 passing vertically downward through the first connecting hole 103 and the lower second connecting hole 201, the second positioning nut 500 and the first positioning nut 400 are pre-screwed into the connecting bolt 300. In this way, when the threaded end 302 of the connecting bolt 300 is fixed in the locking nut 700, the door leaf connector 200 can be locked by tightening the first positioning nut 400 and the second positioning nut 500.

[0024] After the threaded end 302 of the connecting bolt 300 is screwed into the locking nut 700, the vertical height of the connecting bolt 300 relative to the door frame connector 100 can be adjusted by adjusting the length of the threaded end 302 extending beyond the locking nut 700, thereby realizing the adjustment of the installation height of the entire vertically adjustable rotating mechanism.

[0025] After determining the length by which the threaded end 302 of the connecting bolt 300 extends beyond the locking nut 700, the first positioning nut 400 is rotated downwards so that its lower end face contacts the upper end face of the door leaf connector 200, pressing the door leaf connector 200 tightly against the locking nut 700 below. Simultaneously, to better ensure the installation stability of the door leaf connector 200 on the connecting bolt 300—that is, during use, the door leaf connector 200 can rotate synchronously with the connecting bolt 300—after the first positioning nut 400 is tightened downwards, the second positioning nut 500 is rotated downwards so that its lower end face presses against the upper end face of the first positioning nut 400. This double-nut tightening method better ensures that the door leaf connector 200 can rotate synchronously with the connecting bolt 300.

[0026] This application provides a vertically adjustable rotating mechanism. Through the coordinated operation of the door frame connector 100, door leaf connector 200, connecting bolt 300, first positioning nut 400, and second positioning nut 500, the installation height of the revolving door can be flexibly adjusted. The threaded end 302 of the connecting bolt 300 passes through the first connecting hole 103 and the second connecting hole 201 and engages with the locking nut 700, allowing the vertical position of the connecting bolt 300 to be precisely adjusted. Simultaneously, the connecting bolt 300 is rotatably installed within the first connecting hole 103, and can slide up and down relative to the first connecting hole 103, ensuring smooth rotation of the revolving door body. This solves the problem of traditional revolving doors lacking height adjustment and flexibility when installed in commercial or public spaces such as retail stores, showrooms, hotels, and restaurants, significantly improving installation convenience and adaptability to different installation environments.

[0027] In some embodiments described above in this application, the connecting bolt 300 is rotatably installed in the first connecting hole 103 near the head 301 to enable the rotation of the revolving door, while ensuring that the connecting bolt 300 can slide vertically relative to the first connecting hole 103.

[0028] In this regard, this application further proposes that a smooth mounting portion 303 is provided on the connecting bolt 300 near the head 301, and a bearing 600 is mounted on the mounting portion 303. The bearing 600 is installed in the first connecting hole 103, and the smooth mounting portion 303 on the connecting bolt 300 can slide up and down relative to the bearing 600.

[0029] Specifically, the smooth mounting portion 303 refers to the area on the connecting bolt 300 specifically designed for mounting the bearing 600, whose surface is finely machined to have a low surface roughness. For example, a high surface finish can be achieved in this area of ​​the connecting bolt 300 through machining processes such as precision turning, grinding, or polishing, thereby providing a flat, low-friction mounting base for the bearing 600. Furthermore, surface treatments can be applied to this area, such as chrome plating, carburizing and quenching, or applying an anti-friction coating, to further improve its hardness and smoothness, ensuring that the bearing 600 can be installed and operated stably and smoothly.

[0030] A bearing 600 is a mechanical component used to support a rotating shaft or reciprocating motion parts and significantly reduce their kinetic friction. In this embodiment, the bearing 600 is mounted on a smooth mounting portion 303. Its function is to reduce the rotational resistance between the connecting bolt 300 and the first connecting hole 103, thereby improving rotational efficiency and stability. Simultaneously, the smooth mounting portion 303 can move up and down relative to the bearing 600 to accommodate adjustments in the mounting height of the connecting bolt 300. Specifically, a rolling bearing 600 can be used, such as a deep groove ball bearing, angular contact ball bearing, or tapered roller bearing, with its inner ring tightly fitted to the mounting portion 303 and its outer ring fitted to the first connecting hole 103. Alternatively, a sliding bearing can be used, such as an oil-impregnated bearing, a composite bearing, or a plastic bearing, with its inner surface slidingly fitted to the mounting portion 303 and its outer surface fixedly fitted to the first connecting hole 103.

[0031] The bearing 600 is installed in the first connecting hole 103 to provide a stable installation space and support for the bearing 600, ensuring the stability of the rotation center of the connecting bolt 300 within the first connecting hole 103, thereby guaranteeing the smooth rotation of the revolving door. Specifically, the outer ring of the bearing 600 can be pressed into or slid into the first connecting hole 103 by interference fit or clearance fit, and axial fixation can be achieved by means of retaining rings, glands, etc., to prevent the bearing 600 from shifting during rotation.

[0032] In some of the embodiments described above in this application, a door frame connector 100 is proposed for connecting a door frame. However, in its implementation, the structure of the door frame connector 100 may not be stable enough or the installation may be inconvenient, resulting in low efficiency and easy loosening of the revolving door when the door frame is fixed.

[0033] In response, this application further proposes a vertically adjustable rotating mechanism for a revolving door, wherein the door frame connector 100 includes a flat lower connecting part 102 and an upper connecting part 101 extending vertically upward from the inner side of the lower connecting part 102. The upper connecting part 101 and the lower connecting part 102 form an "L" shaped external structure. A first connecting hole 103 is opened on the lower connecting part 102, and upper waist-shaped mounting holes 104 for fixing the door frame connector 100 to the door frame are respectively opened around the upper connecting part 101.

[0034] Specifically, the lower connecting portion 102 in the door frame connector 100 is designed as a flat plate, its main function being to provide a horizontal support surface for supporting and connecting other components. This lower connecting portion 102 can be made from, for example, rectangular or square metal sheets, formed through machining processes such as stamping and cutting; alternatively, it can be cast, for example, from aluminum alloy or steel, to achieve higher strength and precision. The upper connecting portion 101 extends vertically upward from the inner edge of the lower connecting portion 102, forming a vertical connecting surface. Its main function is to provide an interface for connection with the wall and enhance the overall structural rigidity of the door frame connector 100. This upper connecting portion 101 can be integrally formed with the lower connecting portion 102, for example, by bending a metal sheet; alternatively, it can be manufactured separately and then fixed to the inner side of the lower connecting portion 102 by welding, bolting, or other methods. The upper connecting portion 101 and the lower connecting portion 102 together form an "L"-shaped structure. This geometry aims to optimize the fit with the wall and provide structural stability. This L-shaped structure can be formed by bending a metal sheet at a 90-degree angle, such as through cold bending or hot bending processes; alternatively, it can be formed by welding or bolting two separate sheets (lower connecting part 102 and upper connecting part 101) together at a 90-degree angle. A first connecting hole 103 is formed on the lower connecting part 102 to accommodate the mounting portion 303 of the connecting bolt 300, ensuring that the connecting bolt 300 can pass through vertically and reliably connect with the door frame connector 100. This first connecting hole 103 can be formed on the lower connecting part 102 through machining methods such as drilling or punching; alternatively, the hole can be pre-drilled during the casting or molding of the lower connecting part 102. Furthermore, upper connecting parts 101 have waist-shaped mounting holes 104 around their perimeter for fixing the door frame connector 100 to the wall. These upper mounting holes 104 allow fasteners (such as expansion bolts, self-tapping screws, etc.) to pass through, thereby firmly anchoring the door frame connector 100 to the door frame. These waist-shaped mounting holes 104 can be formed on the upper connecting part 101 by drilling, laser cutting or other methods; or, multiple evenly distributed waist-shaped mounting holes 104 can be reserved when casting or molding the upper connecting part 101. The reason for adopting the waist-shaped mounting hole structure is that when the door frame connector 100 is installed on the door frame, its installation position can be flexibly adjusted as needed.

[0035] Through the above technical solution, the door frame connector 100 adopts an L-shaped structure. Its flat lower connecting part 102 provides a stable horizontal support surface, ensuring the foundation balance when connecting the door frame. The upper connecting part 101, which extends vertically upward from the inner side of the lower connecting part 102, not only enhances the overall structural strength of the door frame connector 100 and effectively prevents uneven stress, but its vertical surface also facilitates a tight fit with the wall. The first connecting hole 103 is opened on the lower connecting part 102, ensuring the precise positioning and reliable connection of the connecting bolt 300. Furthermore, the evenly distributed upper waist-shaped mounting holes 104 around the upper connecting part 101 allow the door frame connector 100 to be firmly anchored to the door frame through multiple fixing points, and the installation position can be finely adjusted as needed, thereby significantly improving the stability and ease of installation of the connection between the door frame connector 100 and the door frame. This structural design effectively solves the technical problems in the existing technology where the door frame connector 100 is not stable enough or is inconvenient to install, resulting in low efficiency and easy loosening and falling of the revolving door body when it is fixed in the door frame, thus ensuring the long-term stability and safety of the revolving door operation.

[0036] In some of the solutions described above in this application, a door leaf connector 200 is proposed to connect the revolving door body. However, in this process, if the position of the second connecting hole 201 is not centered or the distribution of the lower waist-shaped mounting holes 202 is uneven, it may cause uneven force on the connection point, affecting the installation stability and smooth operation of the revolving door.

[0037] In this regard, this application further proposes that the second connecting hole 201 is opened at the center of the door leaf connector 200, and the door leaf connector 200 is provided with waist-shaped mounting holes 202 around its perimeter for fixing it to the top of the door frame.

[0038] Specifically, the second connecting hole 201 is located at the center of the door leaf connector 200, meaning that the geometric center of this connecting hole coincides with the geometric center of the door leaf connector 200. This can be achieved in several ways. For example, during the manufacturing process of the door leaf connector 200, a high-precision CNC machine tool can be used to drill or punch according to the preset geometric center coordinates; or, during the design phase, computer-aided design (CAD) software can be used to accurately calculate and position the center of the door leaf connector 200, ensuring that the second connecting hole 201 is formed at this central position. This center-positioning design aims to ensure that the connecting bolt 300 is centered during installation, thereby providing a balanced connection point for the subsequent revolving door body.

[0039] Meanwhile, the door leaf connector 200 has recessed mounting holes 202 on all four sides for fixing it to the top of the door frame. "Recessed on all four sides" means that these mounting holes are not concentrated in a specific area of ​​the door leaf connector 200, but are evenly distributed around its perimeter. For example, elliptical recessed mounting holes 202 can be symmetrically provided at the four corners or the midpoints of the four sides of the door leaf connector 200. Similarly, the recessed mounting holes 202 allow the installation position of the door leaf connector 200 to be flexibly adjusted as needed when it is fixed to the door leaf. Another implementation is to design multiple mounting holes evenly distributed along the edge of the door leaf connector 200 to ensure that the fixing force is evenly transmitted to the top of the door frame. These recessed mounting holes 202 are used to firmly fix the door leaf connector 200 to the top of the door frame using fasteners such as screws and bolts, providing stable support for the entire vertically adjustable rotating mechanism.

[0040] By employing the aforementioned technical solution, the second connecting hole 201 is positioned at the center of the door leaf connector 200, ensuring the centered installation of the connecting bolt 300. This allows the weight and rotational force of the revolving door body to be evenly distributed across the door leaf connector 200, effectively preventing vibration or imbalance caused by uneven loading. Simultaneously, evenly spaced waist-shaped mounting holes 202 are provided around the door leaf connector 200, enabling the fixing force between the door leaf connector 200 and the top of the door leaf to be transmitted through multiple distributed fixing points. This enhances the overall strength and stability of the connection, effectively preventing structural deformation or loosening due to excessive localized stress, and allows for fine-tuning of the installation position as needed. These synergistic design features significantly improve the balance, robustness, and smoothness of the revolving door installation, extend the service life of the mechanism, and reduce maintenance costs.

[0041] In some of the solutions described above in this application, a vertically adjustable rotating mechanism is proposed to realize the rotation of the revolving door and the adjustment of its installation height. However, when directly applied to the revolving door body, it is necessary to ensure the correct integration and functional realization of the mechanism with the revolving door body in order to solve the problem that the existing revolving door cannot adjust its height due to the fixed pivot, resulting in poor installation flexibility.

[0042] In this regard, this application proposes a revolving door, including a revolving door body and a vertically adjustable rotating mechanism for the revolving door, the vertically adjustable rotating mechanism being installed at the top of the revolving door body.

[0043] The revolving door body is the core component of a revolving door, typically comprising door panels, a central axis, and an outer frame structure, serving as the foundation for pedestrian passage and spatial partitioning. This revolving door body can be a traditional three-wing or four-wing structure, with its main frame constructed of metal profiles (such as aluminum alloy or stainless steel) and fitted with glass door panels; alternatively, it can be a custom-designed revolving door with special features (such as curved door panels or irregularly shaped structures) tailored to specific architectural requirements. The revolving door body provides a support platform for the installation of the vertically adjustable rotating mechanism, ensuring the structural integrity and operational stability of the entire revolving door system.

[0044] A vertically adjustable rotating mechanism for revolving doors is a device specifically designed to connect the top of a revolving door to a fixed building structure (such as a ceiling or door frame). It not only supports the weight of the revolving door body but also enables the door to rotate and provides adjustable installation height. This mechanism can be a mechanical structure implemented using components such as a door frame connector 100, a door leaf connector 200, connecting bolts 300, a first positioning nut 400, and a second positioning nut 500, as described in the foregoing embodiments of this application; alternatively, it can be a connecting mechanism including a hydraulic or electric adjustment unit, using a drive device to achieve the lifting and rotating of the revolving door body.

[0045] The vertically adjustable rotating mechanism is installed at the top of the revolving door body, meaning that the lower structure of the vertically adjustable rotating mechanism (e.g., the door leaf connector 200) is physically connected to the top frame or the extension of the central shaft of the revolving door body. This installation method can be achieved through various means, such as welding, bolting, riveting, or snap-fit ​​connections, ensuring the stability and reliability of the connection. Alternatively, the vertically adjustable rotating mechanism can be integrated into a pre-reserved mounting slot or interface in the revolving door body to ensure a tight connection and overall aesthetic integrity. This top-mounted positioning allows the vertically adjustable rotating mechanism to effectively support the entire revolving door body and to adjust its height and control its rotation.

[0046] Through the above technical solution, the revolving door proposed in this application can effectively solve the problem of poor installation flexibility caused by the fixed pivot of existing revolving doors, which prevents height adjustment. Specifically, by integrating and installing a vertically adjustable rotating mechanism with height adjustment and rotation functions at the top of the revolving door body, the entire revolving door system has significant flexibility during installation.

[0047] This vertically adjustable rotating mechanism may include, for example, a door frame connector 100, a door leaf connector 200, a connecting bolt 300, a first positioning nut 400, and a second positioning nut 500. The threaded end 302 of the connecting bolt 300 passes vertically through the first connecting hole 103 of the door frame connector 100 and the second connecting hole 201 of the door leaf connector 200. Through the cooperation of the first positioning nut 400 and the second positioning nut 500, the door leaf connector 200 is clamped and fixed, and the vertical height of the rotating door body is adjusted. When it is necessary to adjust the installation height of the revolving door body, the installation height of the connecting bolt 300 can be adjusted by rotating the threaded end 302 of the connecting bolt 300 into the locking nut 700. The door leaf connector 200 is fixed to the connecting bolt 300 by tightening the first positioning nut 400 and the second positioning nut 500, ensuring that the door leaf connector 200 and the connecting bolt 300 are in a state of synchronous rotation, that is, there will be no relative rotation between the door leaf connector 200 and the connecting bolt 300, thereby achieving precise lifting and lowering of the revolving door body.

[0048] In summary, the revolving door of this application cleverly integrates a vertically adjustable rotating mechanism at the top of the revolving door body, forming a compact and fully functional whole. This not only simplifies the installation process of the revolving door, enabling it to adapt to the height requirements of different architectural spaces, but also enhances the adaptability and convenience of the revolving door in practical applications, thereby significantly improving the overall installation flexibility and practicality of the revolving door.

[0049] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
