Description

Technical Field

[0001] This utility model relates to the field of furniture technology, and in particular to a bed position adjustment mechanism and a position-adjustable bed. Background Technology

[0002] In the field of bed design, the connection between the bed frame and the headboard has evolved from "completely fixed" to "limitedly adjustable." Early beds mostly adopted an integrated structure, with the bed frame and headboard rigidly connected by bolts, and their position could not be adjusted. Although this design was structurally stable, it had obvious limitations: when movable functions were added to the bed frame, the fixed position could easily cause the moving parts to collide and interfere with the headboard, shortening the lifespan of the bed and even posing safety hazards.

[0003] As user needs evolve, the existing fixed bed frame and headboard installation structure has the following problems:

[0004] First, the adjustment dimensions are limited, resulting in insufficient adaptability. Most existing adjustment mechanisms can only achieve adjustment in a single dimension: the distance between the bed frame and the headboard (e.g., sliding back and forth via rails at the bottom of the bed). They cannot adjust the relative position of the two in the parallel direction (aligned with the extension direction of the headboard). This single-dimensional adjustment cannot accommodate distances such as between bedside tables, limiting the flexibility of bed placement.

[0005] Secondly, it cannot accommodate the functional requirements of movable bed boards. With the increasing popularity of electric beds, the bed frame is often equipped with a flip-up backrest (for supporting users to sit up for reading or resting). The existing bed frame installation did not consider the space requirements when the backrest is flipped up. With a fixed bed frame structure, if the distance between the bed frame and the headboard is fixed or the adjustment precision is insufficient, the top of the backrest is prone to colliding with the headboard. At the same time, for different bed models with different sizes of backrests, the installation structure of the bed frame and headboard also needs to be redesigned accordingly to accommodate the movement space required for the backrest to flip up. Utility Model Content

[0006] In view of the shortcomings of the prior art described above, the technical problem to be solved by this utility model is to provide a bed position adjustment mechanism and a position adjustment bed, so as to solve the problems of the single adjustment dimension and incompatibility with the functional requirements of movable bed boards in the existing bed and headboard installation structure.

[0007] To solve the above-mentioned technical problems, this utility model provides a bed position adjustment mechanism for adjusting the relative position between the bed and the headboard, including:

[0008] A vertical fixing frame is vertically mounted on the headboard;

[0009] A transverse fixing frame, wherein the transverse fixing frame is a frame-shaped structure formed by a web and two wing plates vertically fixed to both sides of the web, one end of the web is fixed to the vertical fixing frame, and the transverse fixing frame is horizontally arranged and extends in a direction parallel to the headboard;

[0010] A radial fixing frame is provided, with a sleeve structure adapted to the frame structure at one end and a sliding groove at the other end. The radial fixing frame is horizontally positioned and extends perpendicularly to the headboard. One end of the radial fixing frame is fitted onto the frame structure through the sleeve structure. The bed body is slidably connected to the sliding groove. The relative position of the bed body and the headboard in the parallel direction is adjusted by sliding the sleeve structure along the frame structure. The distance between the bed body and the headboard is adjusted by sliding the bed body along the sliding groove.

[0011] As a more preferred method, the vertical fixing frame is provided with fixing holes, and one end of the web plate is provided with mounting holes that match the fixing holes. Locking elements are used to pass through the mounting holes and positioning holes to fix the horizontal fixing frame and the vertical fixing frame. The advantages are that fixing the horizontal and vertical fixing frames through the mounting holes and fixing holes with locking elements ensures a firm and reliable connection, capable of withstanding long-term stress from the weight of the bed and preventing loosening or shifting during use. Furthermore, it is easy to assemble and disassemble; if adjustments or maintenance are needed later, only the locking elements need to be removed without damaging the overall structure, reducing maintenance costs and operational difficulty.

[0012] As a more preferred approach, the vertical fixing frame is provided with multiple fixing holes, which are arranged vertically at even intervals. The web plate is fixed to the fixing holes at different positions to adjust the vertical height of the transverse fixing member. The advantage is that the multiple vertically spaced fixing holes on the vertical fixing frame can flexibly adjust the vertical installation position of the transverse fixing frame according to the height of the bed or the size of the headboard, so that the adjustment mechanism can be adapted to different specifications of bed and headboard, breaking the limitation of a single size, greatly improving the versatility and adaptability of the mechanism, and eliminating the need to design a separate adjustment mechanism for different bed types.

[0013] As a more preferred embodiment, the vertical fixing frame includes a mounting plate and a fixing plate vertically fixed to one side of the mounting plate, with fixing holes provided on the fixing plate. Its advantage lies in the fact that the vertical fixing frame adopts a split structure of "mounting plate + fixing plate." The mounting plate is responsible for fixing to the headboard, while the fixing plate is specifically used to create fixing holes for connecting the horizontal fixing frame, clearly defining their functions. This design allows for more precise positioning of the fixing holes, facilitates alignment of the horizontal and vertical fixing frames during installation, enhances the structural strength of the vertical fixing frame, prevents deformation due to concentrated stress, and improves support stability.

[0014] As a more preferred method, the mounting plate is provided with a vertically extending mounting slot. A mounting component passes through this slot and is fixed to the headboard. Simultaneously, the vertical height of the mounting plate can be adjusted by adjusting the position of the mounting component within the slot. The advantage is that the vertical mounting slot allows for fine-tuning of the vertical mounting bracket itself, further expanding the height adaptability range. During installation, there is no need for precise alignment with the mounting holes on the headboard; fixing is achieved simply by adjusting the position of the mounting component within the slot, reducing installation precision requirements and operational difficulty, and improving installation flexibility.

[0015] As a more preferred embodiment, the radial fixing frame includes an upper connecting plate, a front side plate perpendicularly fixed to one side of the upper connecting plate, and a rear side plate perpendicularly fixed to the other side of the upper connecting plate. The sliding groove is formed on the upper connecting plate. Its advantages are that the "upper connecting plate + front side plate + rear side plate" structure of the radial fixing frame forms a semi-frame support. The upper connecting plate provides a stable carrier for the sliding groove, ensuring uniform force distribution when the bed slides. The front and rear side plates enhance the structural rigidity of the upper connecting plate, preventing bending and deformation caused by long-term bearing of the bed's weight, extending the service life of the mechanism, and ensuring smooth bed sliding adjustment.

[0016] As a more preferred embodiment, the sleeve structure includes a front through hole and a rear through hole at one end of the front and rear side plates. The frame structure passes through the front and rear through holes and is then inserted into the sleeve structure. Its advantages lie in the fact that the sleeve structure uses a through-hole design on the front and rear side plates, allowing the lateral fixing bracket to directly insert into the through holes. This results in a simple structure with low sliding resistance, smoother adjustment of the radial fixing bracket position without any jamming. Simultaneously, the front and rear through holes provide bidirectional restraint for the lateral fixing bracket, preventing lateral displacement of the radial fixing bracket during adjustment, ensuring precise adjustment direction, and improving operational convenience.

[0017] As a more preferred method, the upper connecting plate is provided with threaded holes and fasteners threaded into the threaded holes. Tightening the fasteners presses one end against the wing plate, locking the sleeve structure to the frame structure. Tightening the fasteners in the opposite direction disengages them from the wing plate. The position of the radial fixing frame is adjusted by sliding the sleeve structure along the extension direction of the frame structure. The advantage is that locking / unlocking the sleeve structure and the transverse fixing frame is achieved by tightening the fasteners; the operation is simple and intuitive, requiring no complex tools, and the user can manually complete the adjustment and locking. When locked, the fasteners and wing plate form a rigid constraint, effectively preventing accidental slippage of the radial fixing frame during use and ensuring the stability of the bed position. Unlocking simply requires reverse tightening, making adjustment flexible and efficient.

[0018] To address the aforementioned problems, this utility model also provides a position-adjustable bed, comprising: a bed frame and a headboard; and the aforementioned bed frame position-adjusting mechanism.

[0019] As a more preferred embodiment, the bed frame includes a bed frame, a front drive unit, and a back panel hinged at one end to the front of the bed frame. The front drive unit drives the back panel to rotate, and the bed position adjustment mechanism fine-tunes the gap between the bed frame and the headboard to prevent interference between the back panel and the headboard when the bed frame is rotated. The advantage is that the bed position adjustment mechanism can fine-tune the gap between the bed frame and the headboard, effectively preventing the back panel from colliding and interfering with the headboard when it rotates under the drive of the front drive unit, protecting the structural integrity of the back panel and headboard, and preventing component damage. Simultaneously, there is no need to limit the adjustment angle of the back panel due to concerns about interference, ensuring that the back panel can normally rotate at multiple angles to meet the needs of users in different usage scenarios such as sitting and lying down, thus improving the functional completeness and user experience of the adjustable bed.

[0020] As a more preferred approach, the position-adjustable bed includes two or more bed position-adjusting mechanisms to make the bed position adjustment smoother.

[0021] As described above, the bed position adjustment mechanism and the position-adjustable bed of this utility model have the following beneficial effects:

[0022] This utility model's bed position adjustment mechanism, through the coordinated operation of vertical, horizontal, and radial fixing frames, achieves two-way functions: "parallel position adjustment" and "distance adjustment" between the bed and headboard. The sleeve structure slides along the horizontal fixing frame, flexibly adjusting the position of both sides of the bed to suit room layout or user habits. The bed slides along the radial fixing frame's sliding groove, precisely controlling the distance between the bed and headboard to meet the space requirements of users of different heights. The overall structural design is simple and stable, preventing bed wobbling during adjustment and improving safety and convenience.

[0023] This utility model of a position-adjustable bed integrates the aforementioned bed position adjustment mechanism, enabling multi-directional adjustment of the bed and headboard to meet users' personalized needs: such as adjusting the position of the sides of the bed according to room space, and adjusting the distance between the bed and headboard according to sleeping habits, thereby improving comfort and space utilization.

[0024] In summary, the bed position adjustment mechanism and position-adjustable bed of this utility model, through the coordinated operation of the vertical fixing frame, the horizontal fixing frame and the radial fixing frame, realize the gap adjustment in two dimensions between the bed and the headboard, solving the problems of the existing bed and headboard installation structure having a single adjustment dimension and being unable to meet the functional requirements of movable bed boards.

[0034] like Figure 2 as well as Figure 3 As shown, this utility model provides a bed position adjustment mechanism for adjusting the relative position between the bed body 4 and the headboard 5, including:

[0035] A vertical fixing frame 1 is vertically mounted on the headboard 5;

[0036] The transverse fixing frame 2 is a frame structure formed by a web plate 21 and two wing plates 22 vertically fixed to both sides of the web plate 21. One end of the web plate 21 is fixed to the vertical fixing frame 1. The transverse fixing frame 2 is horizontally arranged and its extension direction is parallel to the headboard 5.

[0037] A radial fixing frame 3 is provided at one end with a sleeve structure adapted to the frame structure, and at the other end with a sliding groove 311. The radial fixing frame 3 is horizontally positioned and extends perpendicularly to the headboard 5. One end of the radial fixing frame 3 is fitted onto the frame structure through the sleeve structure. The bed body 4 is slidably connected to the sliding groove 311. The relative position of the bed body 4 and the headboard 5 in the parallel direction is adjusted by sliding along the frame structure through the sleeve structure. The distance between the bed body 4 and the headboard 5 is adjusted by sliding the bed body 4 along the sliding groove 311.

[0038] To better illustrate the bed position adjustment mechanism of this utility model, the following specific application will be used as an example: The bed position adjustment mechanism of this utility model, through the coordinated operation of the vertical fixing frame 1, the horizontal fixing frame 2, and the radial fixing frame 3, achieves two-way functions of "parallel position adjustment" and "distance adjustment" between the bed frame 4 and the headboard 5: the sleeve structure slides along the horizontal fixing frame 2 to flexibly adjust the position of both sides of the bed frame 4, adapting to room layout or user habits; the bed frame 4 slides along the sliding groove 311 of the radial fixing frame 3 to precisely control the distance between the bed frame 4 and the headboard 5, meeting the space requirements of users of different heights. The overall structural design is simple and stable, preventing the bed frame 4 from shaking during adjustment, thus improving safety and convenience.

[0039] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the vertical fixing frame 1 is provided with fixing holes 121, and one end of the web plate 21 is provided with mounting holes adapted to the fixing holes 121. A locking member passes through the mounting holes and positioning holes to fix the horizontal fixing frame 2 and the vertical fixing frame 1. The advantages are that fixing the horizontal fixing frame 2 and the vertical fixing frame 1 through the mounting holes and fixing holes 121 with locking members ensures a firm and reliable connection, capable of withstanding long-term stress from the weight of the bed frame 4 and preventing loosening or displacement during use. Furthermore, it is easy to assemble and disassemble; if adjustments or maintenance are needed later, only the locking members need to be removed without damaging the overall structure, reducing maintenance costs and operational difficulty.

[0040] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the locking components include bolts and screws. The advantage of using standard parts such as bolts and screws is that they are highly versatile and readily available, eliminating the need for customized special accessories and reducing procurement and replacement costs. Furthermore, the threaded connections of the bolts and screws are self-locking, preventing loosening due to vibration or force after locking, further ensuring the stability of the connection between the horizontal fixing frame 2 and the vertical fixing frame 1, and improving the overall reliability of the mechanism.

[0041] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3As shown, the vertical fixing frame 1 is provided with multiple fixing holes 121, which are arranged vertically at uniform intervals. The web plate 21 is fixed with the fixing holes 121 at different positions to adjust the vertical height of the transverse fixing member. The beneficial effect is that the multiple vertically spaced fixing holes 121 on the vertical fixing frame 1 can flexibly adjust the vertical installation position of the transverse fixing frame 2 according to the height of the bed frame 4 or the size of the headboard 5, so that the adjustment mechanism can be adapted to different specifications of bed frame 4 and headboard 5, breaking the single size limitation, greatly improving the versatility and adaptability of the mechanism, and eliminating the need to design a separate adjustment mechanism for different bed types.

[0042] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the vertical fixing frame 1 includes a mounting plate 11 and a fixing plate 12 vertically fixed to one side of the mounting plate 11, with fixing holes 121 provided on the fixing plate 12. Its advantage lies in the fact that the vertical fixing frame 1 adopts a split structure of "mounting plate 11 + fixing plate 12". The mounting plate 11 is responsible for fixing to the headboard 5, while the fixing plate 12 is specifically used to create fixing holes 121 to connect to the horizontal fixing frame 2, clearly defining the division of labor. This design allows for more precise positioning of the fixing holes 121, facilitating alignment between the horizontal fixing frame 2 and the vertical fixing frame 1 during installation. It also enhances the structural strength of the vertical fixing frame 1, preventing deformation due to concentrated stress and improving support stability.

[0043] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the mounting plate 11 is provided with a vertically extending mounting slot 111. A mounting component passes through the mounting slot 111 and is fixed to the headboard 5. Simultaneously, the vertical height of the mounting plate 11 can be adjusted by adjusting the position of the mounting component within the mounting slot 111. The advantage is that the vertical mounting slot 111 of the mounting plate 11 allows for fine-tuning of the height of the vertical fixing frame 1 itself, further expanding the height adaptability range. During installation, there is no need to strictly align the mounting holes of the headboard 5; fixing can be completed simply by adjusting the position of the mounting component within the slot, reducing installation accuracy requirements and operational difficulty, and improving installation flexibility.

[0044] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3As shown, the radial fixing frame 3 includes an upper connecting plate 31, a front side plate 32 perpendicularly fixed to one side of the upper connecting plate 31, and a rear side plate 33 perpendicularly fixed to the other side of the upper connecting plate 31. The sliding groove 311 is formed on the upper connecting plate 31. Its beneficial effect is that the "upper connecting plate 31 + front side plate 32 + rear side plate 33" structure of the radial fixing frame 3 forms a semi-frame support. The upper connecting plate 31 provides a stable carrier for the sliding groove 311, ensuring that the force is even when the bed 4 slides. The front and rear side plates 33 can strengthen the structural rigidity of the upper connecting plate 31, avoid bending and deformation of the upper connecting plate 31 due to long-term bearing of the weight of the bed 4, extend the service life of the mechanism, and at the same time ensure the smoothness of the sliding adjustment of the bed 4.

[0045] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the radial fixing frame 3 also includes a lower connecting plate 34, the two sides of which are perpendicularly fixed to the lower edges of the front side plate 32 and the rear side plate 33, respectively. The beneficial effect is that, with the addition of the lower connecting plate 34, the radial fixing frame 3 forms a complete frame structure, significantly improving overall rigidity and deformation resistance. This better distributes the pressure from the weight of the bed frame 4, preventing damage to the side plates or connecting plates due to excessive force. The frame structure also protects the internal space, preventing dust and debris accumulation from affecting sliding adjustment and improving the durability of the mechanism.

[0046] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the sleeve structure includes a front through hole 321 and a rear through hole 331 at one end of the front side plate 32 and the rear side plate 33, respectively. The frame structure passes through the front through hole 321 and the rear through hole 331 and is then inserted into the sleeve structure. Its advantages are that the sleeve structure uses a through hole design on the front and rear side plates 33, allowing the transverse fixing bracket 2 to directly insert into the through holes. This results in a simple structure with low sliding resistance, making the adjustment of the radial fixing bracket 3 smoother and eliminating jamming. Simultaneously, the front and rear through holes 331 provide bidirectional restraint for the transverse fixing bracket 2, preventing the radial fixing bracket 3 from shifting left or right during adjustment, ensuring accurate adjustment direction, and improving operational convenience.

[0047] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3As shown, the upper connecting plate 31 is provided with threaded holes and fasteners 35 threadedly connected to the threaded holes. Tightening the fasteners 35 tightens one end of the fasteners 35 against the wing plate 22, locking the sleeve structure to the frame structure. Tightening the fasteners 35 in the opposite direction disengages the fasteners 35 from the wing plate 22. The position of the radial fixing frame 3 can be adjusted by sliding the sleeve structure along the extension direction of the frame structure. The advantage is that locking / unlocking the sleeve structure and the transverse fixing frame 2 is achieved by tightening the fasteners 35. The operation is simple and intuitive, requiring no complex tools, and the user can manually complete the adjustment and locking. When locked, the fasteners 35 and the wing plate 22 form a rigid constraint, which can effectively prevent the radial fixing frame 3 from sliding accidentally during use and ensure the stability of the bed body 4. Unlocking only requires tightening in the opposite direction, making the adjustment flexible and efficient.

[0048] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the fastener 35 is a bolt; its advantages are that the bolt fastener 35 has a strong locking force due to its threaded connection, which can withstand a large lateral force and prevent gap loosening between the sleeve structure and the lateral fixing bracket 2. At the same time, the bolt has a high degree of standardization and the model is easy to identify. If replacement is needed later, a suitable part can be quickly found, reducing maintenance difficulty and cost; furthermore, there are two fasteners 35.

[0049] In some possible embodiments of this utility model, such as Figure 2 as well as Figure 3 As shown, the web plate 21 has weight-reducing holes 211. The beneficial effect is that, without affecting the load-bearing strength of the web plate 21, the weight-reducing holes 211 effectively reduce the overall weight of the transverse fixing frame 2, facilitating handling and positioning during installation and reducing labor costs. Simultaneously, the weight-reducing design saves material usage, reduces production costs, and promotes air circulation, preventing dust accumulation on the back of the web plate 21 and facilitating cleaning and maintenance.

[0050] To solve the above problems, this utility model also provides a position-adjustable bed, including: a bed body 4 and a headboard 5; and the aforementioned bed body position adjustment mechanism.

[0051] To better illustrate the position-adjustable bed of this utility model, the following specific application will be used as an example: The position-adjustable bed of this utility model integrates the aforementioned bed position adjustment mechanism, enabling multi-directional adjustment of the bed body 4 and headboard 5 to meet the personalized needs of users: such as adjusting the position of both sides of the bed body 4 according to room space, and adjusting the distance between the bed body 4 and headboard 5 according to sleeping habits, thereby improving comfort and space utilization. It can be seen that the bed position adjustment mechanism and position-adjustable bed of this utility model, through the coordinated cooperation of the vertical fixing frame 1, the horizontal fixing frame 2 and the radial fixing frame 3, realize the two-dimensional gap adjustment of the bed body 4 and headboard 5, solving the problems of the single adjustment dimension and incompatibility with the functional requirements of movable bed boards in the existing installation structure of the bed body 4 and headboard 5.

[0052] As a more preferred embodiment, the bed frame 4 includes a bed frame 41, a front drive unit 43, and a back panel 42 hinged at one end to the front of the bed frame 41. The front drive unit 43 drives the back panel 42 to rotate, and the bed position adjustment mechanism fine-tunes the gap between the bed frame 41 and the headboard 5 to prevent the back panel 42 from interfering with the headboard 5 when it flips over. The advantage is that the bed position adjustment mechanism can fine-tune the gap between the bed frame 41 and the headboard 5, effectively preventing the back panel 42 from colliding and interfering with the headboard 5 when it flips over under the drive of the front drive unit 43, protecting the structural integrity of the back panel 42 and the headboard 5, and preventing component damage. At the same time, there is no need to limit the adjustment angle of the back panel 42 due to concerns about interference, ensuring that the back panel 42 can normally achieve multi-angle flipping, meeting the needs of users in different usage scenarios such as sitting and lying down, and improving the functional completeness and user experience of the adjustable bed.

[0053] As a more preferred approach, the position-adjustable bed includes two or more bed position-adjusting mechanisms to make the position adjustment of the bed 4 smoother.

[0054] As described above, the bed position adjustment mechanism and the position-adjustable bed of this utility model have the following beneficial effects:

[0055] 1. Enables bidirectional position adjustment of the bed frame 4 and headboard 5 to meet personalized usage needs.

[0056] The relative position of the bed frame 4 and headboard 5 in the parallel direction can be flexibly adjusted by sliding the sleeve structure along the transverse fixing frame 2 to adapt to different room layouts or user habits. The distance between the bed frame 4 and headboard 5 can be precisely controlled by sliding the bed frame 4 along the radial fixing frame 3 sliding groove 311 to meet the space requirements of users of different heights. The overall structure provides stable support, preventing the bed frame 4 from shaking during adjustment and improving safety and convenience.

[0057] 2. The vertical fixing frame 1 and the horizontal fixing frame 2 are reliably connected, and are easy to disassemble, assemble, and maintain, with strong versatility.

[0058] The connection is secured by standard locking components such as bolts and screws passing through the mounting holes and fixing holes 121, ensuring a firm and self-locking connection that can withstand long-term stress on the bed frame 4 and prevent loosening or displacement. The standard components are highly versatile and readily available, reducing procurement and replacement costs, and subsequent disassembly and maintenance do not require damage to the overall structure. Simultaneously, the multiple vertically evenly arranged fixing holes 121 on the vertical fixing frame 1 allow adjustment of the vertical height of the horizontal fixing frame 2 according to the height of the bed frame 4 or the size of the headboard 5, breaking the limitation of a single size and significantly improving the mechanism's adaptability to different specifications of bed frames 4 and headboards 5.

[0059] 3. The vertical fixing frame 1 has been structurally optimized to improve installation flexibility and structural strength.

[0060] The vertical fixing frame 1 adopts a split structure of "mounting plate 11 + fixing plate 12". The mounting plate 11 is responsible for fixing to the headboard 5, and the fixing plate 12 is specifically used to connect the horizontal fixing frame 2. The division of labor is clear and the positioning is precise, which facilitates installation and alignment, while enhancing the overall structural strength and avoiding stress concentration deformation. In addition, the vertical mounting slot 111 on the mounting plate 11 can realize the fine adjustment of the height of the vertical fixing frame 1 itself, without the need for strict alignment with the mounting holes of the headboard 5, reducing the installation accuracy requirements and improving the flexibility of installation operation.

[0061] 4. The radial fixing bracket 3 has a stable structure, ensuring smooth sliding adjustment and extending service life.

[0062] The semi-frame structure of the radial fixing frame 3, consisting of "upper connecting plate 31 + front side plate 32 + rear side plate 33", provides a stable carrier for the sliding long groove 311, ensuring uniform force distribution when the bed 4 slides. The addition of the lower connecting plate 34 forms a complete frame structure, which can significantly improve the overall rigidity and deformation resistance, better distribute the pressure brought by the weight of the bed 4, avoid damage to components due to excessive force, and prevent the accumulation of dust and debris from affecting the sliding adjustment, thus extending the service life of the mechanism.

[0063] 5. The sleeve structure and locking design improve adjustment accuracy and ease of operation.

[0064] The sleeve structure features a perforated design on the front side plate 32 and the rear side plate 33, allowing the transverse fixing bracket 2 to be directly inserted into the perforations. This minimizes sliding resistance and facilitates smoother adjustment of the radial fixing bracket 3. The front and rear perforations 331 also provide bidirectional limiting for the transverse fixing bracket 2, preventing lateral displacement of the radial fixing bracket 3 during adjustment and ensuring precise adjustment direction. Furthermore, the sleeve structure and the transverse fixing bracket 2 can be locked / unlocked by tightening bolt-like fasteners 35. This simple operation requires no complex tools, and locking effectively prevents accidental sliding of the radial fixing bracket 3 during use, ensuring the stability of the bed frame 4.

[0065] 6. The 21-inch weight-reduction design of the web plate balances practicality and economy.

[0066] The weight-reducing holes 211 on the web plate 21 can effectively reduce the overall weight of the transverse fixing frame 2 without affecting the strength, making it convenient for handling and positioning during installation; at the same time, it reduces the amount of material used, lowers production costs, and facilitates air circulation, preventing dust from accumulating on the back of the web plate 21, making it easier for later cleaning and maintenance.

[0067] 7. The integrated mechanism of the position-adjustable bed offers advantages, adapting to movable bed boards and enhancing the user experience.

[0068] After integrating the bed frame position adjustment mechanism, the position-adjustable bed 4 can achieve multi-directional adjustment, improving user sleep comfort and room space utilization. For the backrest 42 and front drive unit 43 of the bed frame 4, the adjustment mechanism can fine-tune the gap between the bed frame 41 and the headboard 5, preventing collisions and interference between the backrest 42 and the headboard 5 when flipping, protecting the structural integrity of the components, and ensuring that the backrest 42 can be flipped at multiple angles to meet the needs of users in different usage scenarios such as sitting and lying down. Furthermore, setting two or more bed frame position adjustment mechanisms makes the position adjustment of the bed frame 4 smoother.

[0069] The bed position adjustment mechanism and position adjustment bed of this patent, through the coordinated cooperation of the vertical fixing frame 1, the horizontal fixing frame 2 and the radial fixing frame 3, not only realizes the multi-directional adjustment of the bed body 4 and the headboard 5, but also improves the versatility, structural strength and ease of operation of the mechanism through structural optimization. At the same time, it adapts to the functional requirements of movable bed boards, effectively solving the problem of the single adjustment dimension of the installation structure of the bed body 4 and the headboard 5 in the prior art and the inability to be compatible with movable bed boards. The overall structure is simple and stable, which can comprehensively improve the user experience and the practicality of the equipment.

[0070] Therefore, this utility model effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0071] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
