Description

Technical Field

[0001] This utility model relates to the field of partition wall technology, and in particular to a partition wall frame that can be adjusted laterally. Background Technology

[0002] As the construction industry increasingly prioritizes efficiency and sustainability, prefabricated buildings have gained widespread popularity due to their advantages such as rapid construction, low waste, and high precision. Prefabricated partition walls, as a crucial component of prefabricated buildings, offer significant advantages in standardized design and mass production due to their modular and standardized characteristics. However, this characteristic also presents a significant challenge—prefabricated partition walls are typically designed to specific dimensions, limiting their application in non-standard spaces.

[0003] In traditional prefabricated building construction, finished partitions are often prefabricated in a factory and then transported to the site for installation. When encountering spaces with non-modular dimensions, such as irregularly shaped rooms or specific partition requirements, the following two situations arise:

[0004] Customized solutions: Customizing prefabricated partitions to match the dimensions in the factory can solve the problem, but it adds extra costs and time, which contradicts the high-efficiency concept pursued by prefabricated buildings.

[0005] On-site adjustments: Using traditional keel and board materials to build partition walls on-site is not only time-consuming and labor-intensive, but may also damage the uniformity and aesthetics of the finished partition walls, reducing the overall assembly rate and construction speed of the project. Utility Model Content

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, this utility model provides a partition wall frame that can be adjusted laterally, which solves the problems of fixed size and poor adaptability of traditional partition wall frames. The design of the telescopic mechanism realizes the flexible adjustment of the width of the partition wall frame, thereby improving construction efficiency.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0010] A laterally adjustable partition frame includes a fixed frame, a movable frame, and a telescopic mechanism. The movable frame and the fixed frame are slidably and telescopically connected and together form the main structure of the partition frame, which is a rectangular frame. The telescopic mechanism is located inside the rectangular frame and is fixedly connected to the opposite sides of the fixed frame and the movable frame. The telescopic mechanism drives the fixed frame and the movable frame to move towards or away from each other through its own extension and contraction, so that the partition frame can extend and contract laterally.

[0011] This partition wall frame features an adjustable width via a telescopic mechanism, making it suitable for spaces of varying sizes and enhancing its versatility and adaptability. No additional on-site cutting or customization is required; the width can be adjusted simply by operating the telescopic mechanism, significantly saving construction time and labor costs, and improving construction efficiency. It avoids additional costs arising from size mismatches, such as customization fees, material waste, and additional costs due to construction delays. The reduced need for on-site processing lowers potential errors and rework costs. The carefully designed combination of fixed and movable frames, along with the rational layout of the telescopic mechanism, ensures the partition wall frame maintains excellent structural stability and load-bearing capacity in any adjustment state, guaranteeing the safety and lifespan of the partition. The gear-adjustable device makes adjusting the width of the partition wall frame simple and easy; simply rotating a lever achieves the telescopic action, further simplifying the installation process. The ability to adjust the size of the partition wall frame according to actual needs allows for better utilization of indoor space and meets diverse functional requirements.

[0012] In summary, the partition wall frame provided by this utility model not only improves construction efficiency and cost-effectiveness, but also enhances the flexibility and durability of the product, making it very suitable for use in prefabricated buildings.

[0013] Furthermore, the fixed frame is a positive C-shape, including a first vertical beam and fixed crossbeams located at its top and bottom. The movable frame is an inverted C-shape, including a second vertical beam and movable crossbeams located at its top and bottom. The movable frame and the fixed frame are arranged opposite to each other. The fixed crossbeams have a cavity structure to accommodate the sliding and telescoping of the movable crossbeams along the length of the fixed crossbeams.

[0014] The combination of a fixed C-shaped frame and a movable C-shaped frame, arranged in a relative configuration, creates a stable structure, enhancing the overall strength and rigidity of the partition wall frame. The fixed beam is designed as a cavity structure, accommodating the sliding and telescoping of the movable beam along its length, ensuring smooth sliding between the movable and fixed beams and enabling smooth adjustment of the partition wall frame width. Limiting protrusions inside the fixed beam cooperate with limiting grooves along the length of the movable beam, effectively preventing the movable beam from completely detaching from the fixed beam during adjustment, improving safety and reliability. A pulley mechanism at the bottom of the fixed beam, with the bottom edge of the movable beam rolling against it, reduces frictional resistance during telescoping, making the adjustment process easier and smoother.

[0015] The C-shaped and inverted C-shaped designs make the fixed and movable frames more compact, improving space utilization and facilitating transportation and storage. The simple structural design of the fixed and movable frames also makes installation and disassembly easier, reducing installation difficulty and time.

[0016] Furthermore, the telescopic mechanism includes a base beam and a telescopic beam. One end of the base beam is fixedly connected to the first vertical beam, and one end of the telescopic beam is fixedly connected to the second vertical beam. The opposite ends of the base beam and the telescopic beam are telescopically connected to allow free expansion and contraction between the base beam and the telescopic beam.

[0017] The telescopic connection between the base beam and the telescopic beam allows for easy width adjustment of the partition frame, making it suitable for spaces of different sizes and improving the product's versatility and adaptability. The design of the base beam and telescopic beam ensures the structural stability and strength of the partition frame during expansion and contraction, guaranteeing good load-bearing capacity even at maximum extension. The telescopic connection between the base beam and the telescopic beam ensures a smooth expansion and contraction process, reducing friction and resistance during operation and making adjustments easier. The simple connection between the base beam and the telescopic beam makes installing and adjusting the width of the partition frame simple and easy, reducing installation difficulty and time. The telescopic mechanism design avoids additional costs caused by size mismatches, such as customization fees, material waste costs, and additional costs due to construction delays. The precise connection of the base beam and the telescopic beam reduces potential errors and rework costs, ensuring the accuracy and reliability of the partition frame during installation and use. The ability to adjust the size of the partition frame according to actual needs allows for better utilization of interior space and meets different functional requirements.

[0018] Furthermore, the telescopic mechanism also includes a gear adjustment device, which is installed on the base beam and the telescopic beam.

[0019] The gear adjustment device includes a rack structure, a first gear, and a second gear. The rack structure is provided on the top and / or bottom of the telescopic beam. The first gear and the second gear mesh with each other on the base beam. The thickness of the second gear is greater than the thickness of the first gear. The first gear serves as the driving gear, and the second gear serves as the driven gear. The second gear meshes with the rack structure.

[0020] The use of a gear adjustment device ensures precise telescopic adjustment, allowing users to control the width of the partition frame more accurately to meet the requirements of different space dimensions. The meshing mechanism of gears and racks makes the telescopic process smoother, reducing friction and resistance during operation and making adjustment easier. The design of the gear adjustment device enhances the structural stability of the telescopic mechanism, ensuring that the partition frame maintains good load-bearing capacity and structural strength even in its maximum extension state. Through the connection between the rocker arm and the first gear, users can drive the telescopic mechanism with a simple rotation, reducing operational difficulty and time required. The precise meshing of the gears and racks reduces wear between components, extending the service life of the telescopic mechanism. The design of the limit wheels and guide rails ensures the stability and safety of the telescopic beam during telescopic operation, preventing accidental disengagement. The precise gear adjustment device reduces potential errors and rework costs, ensuring the accuracy and reliability of the partition frame during installation and use.

[0021] Furthermore, the gear adjustment device also includes a support device, a guide rail, and a limiting wheel. The support device supports the first gear and the second gear respectively, and the side wall of the support device near the first gear is provided with a guide rail. The movable end of the telescopic beam is provided with a limiting wheel that can move along the guide rail.

[0022] The support device design ensures the stability of the first and second gears during operation, preventing gear wobbling during rotation and improving the smoothness of the adjustment process. The guide rail provides a precise guiding path for the limit wheel, ensuring the linear movement of the telescopic beam during extension and retraction, improving the accuracy and smoothness of the process. The cooperation between the limit wheel and the guide rail effectively prevents the telescopic beam from deviating from the predetermined track during extension and retraction, providing limit protection and avoiding the risk of damage to the telescopic mechanism. The cooperation between the limit wheel and the guide rail ensures the stability and safety of the telescopic beam during extension and retraction, preventing accidental disengagement. The design of the support device and guide rail makes the operation of the gear adjustment device smoother, reducing operational difficulty and time required.

[0023] Furthermore, the base beam is provided with a through hole, which corresponds to the axis of the first gear. A rocker arm can pass through the through hole so that the rocker arm can be detachably connected to the axis of the first gear. After the rocker arm is removed, a detachable cover can be installed at the through hole.

[0024] The detachable connection between the joystick and the first gear allows users to easily adjust the width of the partition frame, making operation simple and convenient. The detachable design of the joystick allows it to be removed when adjustment is not needed, facilitating other operations and also making it easy to store and transport. After removal, the through-hole can be sealed with a snap-on cover, which is both aesthetically pleasing and reduces unnecessary space occupation. The snap-on cover design prevents potential safety hazards caused by the through-hole being exposed when the joystick is not in use, such as clothing or tools accidentally getting stuck in the through-hole.

[0025] Furthermore, a limiting groove is provided along the length of the movable crossbeam, and a limiting protrusion is provided inside the fixed crossbeam. The limiting protrusion and the limiting groove cooperate to limit the movable crossbeam to completely detach from the fixed crossbeam.

[0026] The combined use of the limiting protrusions and limiting grooves effectively prevents the movable crossbeam from completely detaching from the fixed crossbeam during extension and retraction, improving the structural stability of the partition frame. The limiting design ensures the safety of the movable crossbeam during adjustment, avoiding safety hazards caused by accidental detachment. The tight fit between the limiting protrusions and limiting grooves enhances the connection strength between the movable and fixed crossbeams, ensuring the partition frame maintains good structural stability even in its maximum extension state. The precise fit of the limiting protrusions and limiting grooves reduces direct contact between the movable and fixed crossbeams, thereby reducing wear and extending the service life of the partition frame. The limiting design reduces potential errors and rework costs, ensuring the accuracy and reliability of the partition frame during installation and use. The design of the limiting protrusions and limiting grooves makes the adjustment process smoother, reducing operational difficulty and time required.

[0027] Furthermore, multiple sets of pulley mechanisms are installed at the bottom of the fixed crossbeam, and there is a gap at the bottom edge of the movable crossbeam, with the bottom edge of the movable crossbeam being rolledly connected to the pulley mechanisms respectively.

[0028] The pulley mechanism design reduces friction during the extension and retraction of the movable crossbeam, making the operation smoother and reducing operational resistance. The rolling connection between the pulleys and the bottom edge of the movable crossbeam reduces wear caused by direct contact, extending the service life of the partition frame. The pulley mechanism also makes the adjustment process smoother, reducing operational difficulty and time. Furthermore, the pulley mechanism ensures the safety of the movable crossbeam during extension and retraction adjustments, preventing safety hazards caused by accidental jamming of the crossbeam.

[0029] Furthermore, the pulley mechanism includes a mounting base, a support rod, and a roller. The mounting base is located at the middle of the bottom end of the fixed crossbeam and in the gap between the bottom edge of the movable crossbeam. One end of the support rod is fixedly connected to the mounting base, and the other end is equipped with a roller, which is in rolling connection with the bottom edge of the movable crossbeam. The support rod is shaped like an oblique "7" and is set at an angle to the length direction of the fixed crossbeam.

[0030] The design of the slanted "7"-shaped support rod ensures stable rolling of the rollers on the bottom edge of the movable crossbeam, improving the stability of the movable crossbeam during its extension and retraction. The support rod is angled relative to the length of the crossbeam to ensure a rolling connection between the rollers and the movable crossbeam.

[0031] Furthermore, there is at least one set of partition wall frames, and multiple sets of partition wall frames are connected by overlapping connecting blocks.

[0032] The modular partition wall frames are connected by overlapping connecting blocks, enhancing the overall structural stability and ensuring the robustness and reliability of multiple partition wall frames when used together. The connecting block design helps to distribute the load, improving the overall load-bearing capacity of the partition wall frame and ensuring its structural stability and safety when bearing weight.

[0033] (III) Beneficial Effects

[0034] The beneficial effects of this utility model are as follows: It provides a horizontally adjustable partition frame. Because the width of the partition frame can be adjusted via a telescopic mechanism, it can adapt to various space sizes, providing suitable partition solutions for both standard and non-standard spaces. This avoids the problem of traditional partitions being unable to adapt to changing environments due to fixed dimensions. No additional cutting or customization work is required on-site; the width of the partition frame can be adjusted simply by operating the telescopic mechanism, greatly saving construction time and labor costs and improving construction efficiency. It avoids additional costs caused by size mismatches, such as customization fees, material waste costs, and additional costs due to construction delays. At the same time, reducing the need for on-site processing also reduces potential errors and rework costs. Through the carefully designed combination of fixed and movable frames, and the reasonable layout of the telescopic mechanism, the partition frame maintains good structural stability and load-bearing capacity in any adjustment state, ensuring the safety and service life of the partition.

In this document, directional terms such as "upper," "lower," etc., are used interchangeably with other directional terms. Figure 2 The orientation is used as a reference.

[0058] To better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present invention can be understood more clearly and thoroughly, and that the scope of the present invention can be fully conveyed to those skilled in the art.

[0059] Example 1:

[0060] See Figure 1 and Figure 2 A laterally adjustable partition wall frame is disclosed. The partition wall frame includes a fixed frame, a movable frame, and a telescopic mechanism. The movable frame and the fixed frame are slidably and telescopically connected and together form the main structure of the partition wall frame, which is a rectangular frame. The telescopic mechanism is located inside the rectangular frame and is fixedly connected to the opposite sides of the fixed frame and the movable frame. The telescopic mechanism, through its own extension and retraction, drives the fixed frame and the movable frame to move towards or away from each other, thereby enabling the partition wall frame to extend and retract laterally.

[0061] When moving in opposite directions, the crossbeams of the movable frame extend from the crossbeam section of the fixed frame, widening the partition wall frame. When moving towards each other, the crossbeams of the movable frame move into the crossbeam cavity of the fixed frame, narrowing the partition wall frame.

[0062] The partition frame is installed at the location of the partition to be installed, such as between two parallel walls. A fixed frame is attached to one wall, and a movable frame is stretched to attach to the other wall to complete the partition. Alternatively, the partition frame can be used to form the four walls of a partitioned room, and the size of the partitioned room can be changed by adjusting the distance between the movable and fixed frames. After adjusting the distance, the partition frame is fixed using either a wet or dry method. The wet method involves pouring cement to shape the frame, while the dry method includes bolting or welding.

[0063] See Figure 1 and Figure 2 The fixed frame is a positive C-shape, including a first vertical beam and fixed horizontal beams located at its top and bottom. The movable frame is an inverted C-shape, including a second vertical beam and movable horizontal beams located at its top and bottom.

The fixed horizontal beam has a cavity structure to accommodate the movable horizontal beam sliding and extending along the length of the fixed horizontal beam.

The thickness of the second gear is greater than that of the first gear. The first gear acts as the driving gear, and the second gear acts as the driven gear. The second gear meshes with the rack structure. The additional thickness of the second gear is used for meshing with the rack structure.

[0067] See Figure 5 The gear adjustment device also includes a support device, a guide rail, and a limiting wheel. The support device supports the first gear and the second gear respectively, and the guide rail is provided on the side wall of the support device near the first gear. The movable end of the telescopic beam is provided with a limiting wheel that can move along the guide rail.

[0068] See Figure 1 and Figure 2 The base beam is provided with a through hole, which corresponds to the axis of the first gear. A rocker arm can pass through the through hole so that the rocker arm can be detachably connected to the axis of the first gear. After the rocker arm is removed, a cover can be provided at the through hole to prevent the first gear from rotating.

[0069] See Figure 2 , Figure 7 and Figure 8 A limiting groove is provided along the length of the movable crossbeam, and a limiting protrusion is provided inside the fixed crossbeam. The limiting protrusion and the limiting groove cooperate to limit the movable crossbeam to completely detach from the fixed crossbeam.

[0070] See Figure 9 and Figure 10 Multiple sets of pulley mechanisms are installed at the bottom of the fixed crossbeam, and there is a gap at the bottom edge of the movable crossbeam. The bottom edge of the movable crossbeam is rolledly connected to the pulley mechanisms respectively.

[0071] See Figure 10 and Figure 11 The pulley mechanism includes a mounting base, a support rod, and rollers. The mounting base is located at the middle of the bottom end of the fixed crossbeam and in the gap between the bottom edge of the movable crossbeam. One end of the support rod is fixedly connected to the mounting base, and the other end is equipped with a roller, which is in rolling connection with the bottom edge of the movable crossbeam.

[0072] The support rod is shaped like a slanted "7" and is set at an angle to the length of the fixed crossbeam.

[0073] See Figure 1 and Figure 2There is at least one set of partition wall frames, and multiple sets of partition wall frames are connected by overlapping connecting blocks.
