Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of assembled walls, in particular to a vertically adjustable partition wall system. Background Art
[0002] Prefabricated construction methods have gained widespread adoption in the modern construction industry due to their significant efficiency advantages and cost-saving potential. The use of prefabricated walls is a key component of this trend. Prefabricated walls, particularly prefabricated partition walls, are standardized and manufactured in factories, significantly reducing on-site construction time and labor costs, thereby accelerating the overall construction project process.
[0003] However, despite the advantages of standardized production, prefabricated walls have limitations when faced with non-standard installation environments. Specifically, when the height of the on-site installation area does not match the standard dimensions of the prefabricated prefabricated walls, traditional solutions include two approaches:
[0004] Factory customization: Redesigning and producing finished walls to meet the specific dimensions of the site. While this method can theoretically meet dimensional requirements, it actually adds additional production time and costs, violating the efficiency principle pursued by prefabricated construction.
[0005] On-site adjustment: Standard-sized finished walls are transported to the site, and then cut or additional materials are added to accommodate the actual height. While this method avoids the waiting time of re-production, on-site processing not only consumes more manpower and time, but may also affect the structural integrity and performance of the wall. Utility Model Content
[0006] (1) Technical issues to be solved
[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a vertically adjustable partition wall system, which solves the technical problem that the height of the partition wall cannot be adjusted vertically.
[0008] (2) Technical solution
[0009] In order to achieve the above-mentioned purpose, the main technical solutions adopted by this utility model include:
[0010] The present invention provides a vertically adjustable partition wall system, comprising a fixed keel frame, a movable keel frame, and a telescopic mechanism. The movable keel frame is liftably plugged into the fixed keel frame. The telescopic mechanism is disposed on the fixed keel frame and is in transmission connection with the movable keel frame to switch between an initial state and an extended state.
[0011] In the initial state, the bottom and top of the movable keel frame respectively abut against the bottom and top of the fixed keel frame;
[0012] The bottom and top of the movable keel frame are supported by the bottom and top of the fixed keel frame respectively, and the telescopic mechanism can also play a certain supporting role.
[0013] In the extended state, the movable keel frame moves in the vertical direction through the telescopic mechanism. The height of the movable keel frame is higher than that of the fixed keel frame, and the movable keel frame is supported by the telescopic mechanism.
[0014] The telescopic mechanism allows the partition system to quickly and flexibly adjust the wall height on-site to suit different installation environments, eliminating the need for factory customization or complex on-site fabrication. This significantly enhances the finished partition's adaptability to spaces of varying heights. In its initial state, the partition system is compact, making it easy to transport and store. This makes installation quick and easy when the installation height matches the fixed keel frame. This avoids the additional production and transportation costs associated with dimensional mismatches, reduces material waste and labor costs required for on-site fabrication, and lowers overall project costs. In the extended state, the movable keel frame is supported by the telescopic mechanism, ensuring the partition system maintains excellent structural stability and safety even after height adjustments.
[0015] Optionally, the telescopic mechanism includes a screw assembly and a drive assembly, which are respectively arranged vertically and horizontally in the fixed keel frame; the screw assembly is detachably connected to the fixed keel frame and the movable keel frame and is engaged with the drive assembly.
[0016] The lead screw assembly converts thread motion into linear motion, providing precise vertical adjustment capability and ensuring that the movable keel frame can move smoothly and accurately in the vertical direction.
[0017] By operating the driving component (such as rotating the first gear member), the lifting and lowering of the movable keel frame can be easily controlled. The operation is simple and easy for on-site workers to master.
[0018] The coordinated use of the lead screw assembly and the drive assembly ensures stable support of the movable keel frame in the extended state, and maintains good structural stability and safety even at a higher position.
[0019] Optionally, the screw assembly includes a screw device, a gear assembly and a support shaft, the screw device includes a screw shaft and a nut carrier, and the nut carrier is detachably mounted on the movable keel frame and screwed with the screw shaft;
[0020] The lower end of the screw shaft is fixedly connected to the gear assembly, the gear assembly is meshed with the drive assembly, the lower end of the gear assembly is rotatably connected to the upper end of the support shaft, and the lower end of the support shaft is fixedly connected to the bottom of the fixed keel frame.
[0021] The screw device provides precise linear motion control through the cooperation of the screw shaft and the nut carrier, which can ensure that the movable keel frame moves smoothly and accurately in the vertical direction to achieve fine adjustment of the height.
[0022] The fixed connection between the screw shaft and the gear assembly and the rotational connection between the gear assembly and the support shaft ensures stable support of the movable keel frame in the extended state, maintaining the stability and safety of the structure even at a higher position.
[0023] Optionally, the screw device further includes a threaded roller limiting layer, and the threaded roller limiting layer is arranged on the top of the screw shaft.
[0024] The threaded roller stopper prevents the nut carrier from dislodging when the screw shaft reaches its highest position, providing a physical stop and ensuring the safety and stability of the active keel frame when extended. This stopper reduces the likelihood of direct contact between the nut carrier and the top of the screw shaft, helping to reduce wear and extend the life of the screw assembly.
[0025] Optionally, the gear assembly includes a screw gear and a turntable, the screw gear is meshed with the drive assembly, the upper end of the screw gear is fixedly connected to the screw shaft, the turntable is detachably arranged at the lower end of the screw gear and rotates synchronously with the screw gear, and the turntable is rotatably connected to the support shaft.
[0026] The screw gear is meshed with the driving assembly to ensure efficient power transmission, so that the movable keel frame can move smoothly in the vertical direction.
[0027] The screw gear is fixedly connected to the screw shaft, which ensures the stability of the screw shaft during rotation and improves the working efficiency and reliability of the entire telescopic mechanism.
[0028] The turntable rotates synchronously with the lead screw gear, and the turntable is rotationally connected to the support shaft, providing the gear assembly with rotational feasibility.
[0029] Optionally, the drive assembly includes a first gear device and two second gear devices; the first gear device is arranged on the fixed keel frame, and one end of the second gear device is meshed with the first gear device and the other end is meshed with the screw gear.
[0030] The coordination of the first gear unit and the two second gear units enables efficient power transmission from the drive source to the lead screw gear, ensuring smooth and efficient vertical movement of the movable keel frame. The first gear unit, serving as the power input, is easy to operate, allowing the operator to easily control the raising and lowering of the movable keel frame using simple tools (such as a cross-knob tool).
[0031] The design of one first gear device and two second gear devices makes the entire drive assembly compact and easy to integrate into the fixed keel frame, saving space.
[0032] Through the combined use of gear devices, the partition wall system can flexibly respond to various installation height requirements, improving the product's adaptability and market competitiveness.
[0033] Optionally, the first gear device includes a first gear member and a gear support rod, the first gear member is rotatably assembled on one end of the gear support rod, and its rotation direction rotates along the axis of the gear support rod, and the other end of the gear support rod is fixed in the fixed keel frame.
[0034] The first gear member serves as the power input end and is assembled on one end of the gear support rod by rotation, ensuring that power can be smoothly transmitted from the external operating tool (such as the cross knob tool) to the gear system, thereby driving the lifting and lowering of the movable keel frame.
[0035] The other end of the gear support rod is fixed in the fixed keel frame, providing a stable support for the first gear member and ensuring the stability of the first gear member during the rotation process.
[0036] By fixing the gear support rod in the fixed keel frame, it not only ensures the stability of the structure, but also facilitates maintenance and inspection, thus extending the service life of the system.
[0037] Through precise power transmission and stable structural design, the need for on-site processing is reduced, installation costs and time consumption are lowered, and the efficiency and economy of prefabricated construction are improved.
[0038] Optionally, the second gear assembly includes second gear members at both ends, a positioning force transmission roller, and a positioning roller support member. The positioning roller support member supports the gears at both ends. The positioning force transmission roller is sleeved on the positioning roller support member and mounted on the fixed keel frame. A support plate is provided on the back of the fixed keel frame, and the positioning roller support member and the gear support rod are connected to the support plate.
[0039] The positioning force transmission roller and the positioning roller support ensure accurate transmission between the second gear components, so that power can be efficiently transmitted from the first gear device to the lead screw gear, thereby driving the lifting and lowering of the movable keel frame.
[0040] The positioning roller support member supports the second gear members at both ends, ensuring the stability and accuracy of the gears during the transmission process.
[0041] The support plate provided on the back of the fixed keel frame further enhances the structural stability of the system and ensures the firm fixation of the gear support rod and the positioning roller support.
[0042] Optionally, the fixed keel frame and the movable keel frame have the same length and width, a slot is provided on the side wall of the fixed keel frame, and the width of the slot is smaller than the width of the movable keel frame; a plug rod is provided on the side wall of the movable keel frame, and the plug rod is inserted into the slot.
[0043] By inserting the insert rods of the movable keel frame into the slots of the side walls of the fixed keel frame, a stable connection is formed, thereby ensuring the structural stability and safety of the movable keel frame in the extended state.
[0044] The width of the slot is smaller than the width of the movable keel frame. This design ensures the precise guidance of the movable keel frame in the vertical direction, avoids shaking during the lifting process, and improves the overall stability of the system.
[0045] The use of the rods and slots makes the installation of the movable keel frame simple and quick, without the need for complicated fixing devices or fasteners, reducing installation time and cost.
[0046] The design of the plug-in rods and slots allows the movable keel frame to be easily disassembled from the fixed keel frame, facilitating maintenance and inspection and extending the service life of the system.
[0047] Optionally, a damping sealing rubber pad is provided on the top of the movable keel frame; and a plurality of weight-reducing holes are provided on the side wall of the movable keel frame.
[0048] The setting of the damping sealing pad can effectively isolate external noise and improve the sound insulation effect of the partition wall system. At the same time, it can also play a certain sealing role to prevent dust and moisture from entering.
[0049] The damping sealing rubber pad contacts the top surface when the movable keel frame is raised to the highest position, which can provide a buffering effect, reduce collision noise, and improve the comfort of the living or office environment.
[0050] By opening a plurality of weight-reducing holes on the side wall of the movable keel frame, the overall weight of the movable keel frame can be effectively reduced, making the operation of the partition wall system easier and reducing the difficulty of operation.
[0051] The design of the weight-reducing holes not only reduces weight, but also maintains or improves the structural strength of the movable keel frame by optimizing the position and size of the holes, ensuring the stability and safety of the system.
[0052] (3) Beneficial effects
[0053] The beneficial effects of the present invention are as follows: the present invention provides a finished partition wall that can be telescopically adjusted longitudinally. In the initial state, the movable keel frame is at its lowest position, and its bottom and top are supported by the bottom and top of the fixed keel frame respectively. At this time, the movable keel frame fits tightly with the fixed keel frame to form a whole. The partition wall system is in the most compact state, takes up the least space, and is easy to transport and store. In this state, the entire system is stable and is suitable for occasions where the installation height matches the fixed keel frame. When the height of the partition wall system needs to be adjusted to adapt to different installation environments, the telescopic mechanism comes into play. The movable keel frame moves in the vertical direction through the telescopic mechanism, and the movable keel frame is able to extend vertically. As the movable keel frame rises, it gradually separates from the top support of the fixed keel frame until it reaches the desired height. During this process, the movable keel frame is supported by the telescopic mechanism, ensuring the stability of the structure.
[0054] The telescopic mechanism increases the adaptability of the finished wall in the longitudinal space, especially when facing the needs of continuous installation at different heights. The wall height can be adjusted quickly and flexibly without relying on factory customization or on-site processing, thereby greatly improving the efficiency and economy of prefabricated construction.

[0068] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below with reference to the accompanying drawings and through specific embodiments. Figure 1 The orientation is referenced.
[0069] This application provides a prefabricated wall that can be adjusted vertically. This allows the partition system to quickly and flexibly adjust the wall height without relying on factory customization or on-site processing, thereby greatly improving the efficiency and economy of prefabricated construction. In its initial state, the partition system is in its most compact state, which is convenient for transportation and storage and has standardized characteristics. In the extended state, the height can be adjusted according to actual installation requirements, increasing the longitudinal adaptability of standard-height prefabricated walls and solving the height difference problem encountered in the horizontal continuous installation of prefabricated walls. The application of the partition wall saves time and labor costs in on-site construction.
[0070] The telescopic mechanism increases the adaptability of the finished partition wall in the longitudinal space. Especially when facing the needs of continuous installation at different heights, the wall height can be adjusted quickly and flexibly without relying on factory customization or on-site processing, thereby greatly improving the efficiency and economy of prefabricated construction and solving the height difference problem encountered in the horizontal continuous installation of the finished partition wall.
[0071] To better understand the above technical solution, 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 accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.
[0072] Example 1:
[0073] See also Figure 1 and Figure 3A vertically adjustable partition system includes a fixed keel frame 1, a movable keel frame 2 and a telescopic mechanism 3. The movable keel frame 2 can be lifted and plugged into the fixed keel frame 1. The telescopic mechanism 3 is arranged on the fixed keel frame 1 and is transmission-connected to the movable keel frame 2 to switch between an initial state and an extended state.
[0074] In the initial state, the bottom and top of the movable keel frame 2 abut against the bottom and top of the fixed keel frame 1 respectively.
[0075] In the extended state, the movable keel frame 2 moves in the vertical direction through the telescopic mechanism 3 . The movable keel frame 2 is higher than the fixed keel frame 1 , and the movable keel frame 2 is supported by the telescopic mechanism 3 .
[0076] See also Figure 1 and Figure 2 The telescopic mechanism 3 includes a screw assembly 31 and a drive assembly 32, which are respectively arranged vertically and horizontally in the fixed keel frame 1. The screw assembly 31 is detachably connected to the fixed keel frame 1 and the movable keel frame 2 and is engaged with the drive assembly 32.
[0077] See also Figure 1 and Figure 2 The screw assembly 31 includes a screw device 311, a gear assembly 312 and a support shaft 313. The screw device 311 includes a screw shaft 3111 and a nut carrier 3112. The nut carrier 3112 can be detachably mounted on the movable keel frame 2 and screwed together with the screw shaft 3111.
[0078] The nut carrier 3112 is preferably a T-nut, because the T-nut has self-locking properties.
[0079] The lower end of the screw shaft 3111 is fixedly connected to the gear assembly 312, the gear assembly 312 is meshed with the drive assembly 32, the lower end of the gear assembly 312 is rotatably connected to the upper end of the support shaft 313, and the lower end of the support shaft 313 is fixedly connected to the bottom of the fixed keel frame 1.
[0080] See also Figure 1 The screw device 311 also includes a threaded roller limiting layer 3113, which is arranged on the top of the screw shaft 3111.
[0081] See also Figure 1 and Figure 2The gear assembly 312 includes a screw gear 3121 and a turntable 3122. The screw gear 3121 is meshed with the driving assembly 32. The upper end of the screw gear 3121 is fixedly connected to the screw shaft 3111. The turntable 3122 is detachably arranged at the lower end of the screw gear 3121 and the turntable 3122 rotates synchronously with the screw gear 3121. The turntable 3122 is rotatably connected to the support shaft 313.
[0082] See also Figure 1 and Figure 2 The driving assembly 32 includes a first gear device 321 and two second gear devices 322. The first gear device 321 is arranged on the fixed keel frame 1, and one end of the second gear device 322 is meshed with the first gear device 321 and the other end is meshed with the screw gear 3121.
[0083] See also Figure 1 and Figure 2 The first gear device 321 includes a first gear part 3211 and a gear support rod 3212. The first gear part 3211 is rotatably assembled on one end of the gear support rod 3212, and its rotation direction rotates along the axis of the gear support rod 3212. The other end of the gear support rod 3212 is fixed in the fixed keel frame 1.
[0084] See also Figure 1 and Figure 2 The second gear device 322 includes a second gear member 3221 at both ends, a positioning force transmission roller 3222 and a positioning roller support member 3223. The positioning roller support member 3223 supports the second gear member 3221 at both ends. The positioning force transmission roller 3222 is sleeved on the positioning roller support member 3223 and installed on the fixed keel frame 1.
[0085] The first gear 3211 serves as a driving wheel, and the second gear 3221 serves as a driven wheel.
[0086] A cross-shaped knob is provided at the end of the first gear member 3211, and a cross-shaped knob tool is inserted into the cross-shaped knob of the first gear member 3211 to rotate the first gear member. Of course, a limiting device can also be installed at the bottom of the fixed keel frame 1. The limiting device is configured as a telescopic rod, and a cross-shaped knob structure is provided at the end of the limiting device. When the first gear member 3211 needs to be rotated, the telescopic rod is retracted to make way for the cross-shaped knob tool. When the first gear member 3211 does not need to be rotated, the telescopic rod is extended, and the cross-shaped knob structure at the end of the limiting device is inserted into the cross-shaped knob. Because the lower end of the telescopic rod is fixed, unnecessary rotation of the first gear member can be prevented.
[0087] See also Figure 3The fixed keel frame 1 and the movable keel frame 2 have the same length and width. A slot is provided on the side wall of the fixed keel frame 1, and the width of the slot is smaller than the width of the movable keel frame 2. A plug rod 21 is provided on the side wall of the movable keel frame 2, and the plug rod 21 is inserted into the slot.
[0088] See also Figure 3 A damping sealing pad 22 is provided on the top of the movable keel frame 2; and a plurality of weight-reducing holes 23 are provided on the side wall of the movable keel frame 2.
[0089] Furthermore, to further enhance the supporting performance of the movable keel frame 2 of this application, after it is raised to the designated position, the damping sealant 22 abuts the roof. Then, welded columns 24 are fixedly connected between the lower end of the movable keel frame and the fixed keel frame 1. If the welded columns 24 are thicker, they can also serve as weld blocks. Because only a few welds are required, on-site fabrication time is shortened. Welded columns 24 are typically added to load-bearing walls; ordinary partition walls normally do not require additional welded columns 24.
[0090] How it works
[0091] Step 1: Start the telescopic mechanism 3:
[0092] The drive assembly 32 is activated by rotating the first gear member using a cross-knob tool.
[0093] Step 2: The driving component 32 works:
[0094] The rotation of the first gear member 3211 drives the second gear members 3221 on the left and right sides meshing with the first gear member 3211 to rotate.
[0095] Through the positioning force transmission roller 3222 and the positioning roller support member 3223 , the second gear member 3221 on one side drives the second gear member 3221 on the other side to rotate.
[0096] Step 3: The screw assembly 31 moves:
[0097] The second gear member 3221 meshes with the lead screw gear 3121 to drive the lead screw gear 3121 to rotate.
[0098] The rotation of the screw gear 3121 causes the screw shaft 3111 to rotate accordingly.
[0099] The nut bearing member 3112 screwed with the screw shaft 3111 moves axially along the screw shaft 3111 , thereby driving the movable keel frame 2 to rise.
[0100] Step 4: Reach the specified height:
[0101] When the movable keel frame 2 is raised to a desired height, the first gear member 3211 stops rotating.
[0102] Optionally, a welding column 24 is fixedly connected between the lower end of the movable keel frame 2 and the fixed keel frame 1 to enhance the supporting performance.
