[0029] In the prior art, the lifting frame widely used in the household industry relies on the guide rail structure to maintain stability and adjust the height. Such traditional structure has obvious defects, the introduction of guide rail makes it difficult to reduce the overall volume, which limits the adaptability in compact space, and the processing, installation and maintenance cost of guide rail is high, which is not conducive to the popularization of products. For example, in a small kitchen or bathroom environment, it is necessary to flexibly adjust the height of the storage rack to adapt to different use requirements, but the cumbersome and high cost of the existing structure makes it difficult to meet such scenarios.

[0030] To solve the above problems, the inventors noticed that the complex structure of the guide rail is the root cause of the volume and cost problems, and tried to explore the possibility of removing the guide rail. Through analysis, it was found that the core of stable lifting is the effective combination of power transmission and movement guidance, rather than relying on the physical constraints of the guide rail. After further thinking, it is proposed to directly drive the moving part with the driving part to perform linear motion, and to combine the moving frame with the moving part through detachable connection, which simplifies the structure and retains the function.

[0031] Therefore, referring to Figure 1 and Figure 2 , the present application proposes a lifting frame comprising a frame body 10, a driving part 20, a moving part 30 and a moving frame 40. The frame body 10 is used to be installed at a predetermined position; the driving part 20 is installed on the frame body 10; the moving part 30 is movably connected to the frame body 10 and in driving connection with the driving part 20; the moving frame 40 is detachably connected with the moving part 30, and is used to be detachably connected with a product to be lifted.

[0032] The frame body 10 refers to a support structure that carries other components, which can be realized by a metal frame or a plate assembly, and its installation method can be completed by bolt fixation or welding, and its function is to provide a stable basis for lifting movement. The driving part 20 refers to a power generating device, for example, an electric motor, which is connected to the moving part 30 through a transmission shaft or a gear, and its function is to provide controllable power output for lifting. The moving part 30 refers to a component that moves along a predetermined path, for example, a structure that cooperates with a screw 12 through a nut, which converts rotary motion into linear motion, and its function is to transmit the power of the driving part 20 to the moving frame 40. The moving frame 40 refers to a platform that carries products, for example, a metal frame with buckles or slots, which is connected to the moving part 30 through a quick release interface, and its function is to adapt to different sizes or types of products to be lifted.

[0033] After the frame body 10 is fixed to the wall or the floor, the driving part 20 is started and drives the moving part 30 to move linearly along the frame body 10. The moving part 30 and the moving frame 40 are connected through a plug-in or lock structure, and when the moving part 30 moves, the moving frame 40 is lifted synchronously. The product to be lifted is fixed on the moving frame 40 by hooks, clamping parts or magnetic attraction devices, which can be quickly disassembled according to the needs. During the whole process, the movable connection of the moving part 30 and the frame body 10 replaces the guiding function of the traditional guide rail, and precise control is achieved through the direct transmission of the driving part 20 and the moving part 30, without the need for additional guiding structure.

[0034] The application replaces the heavy guide rail system through the transmission mode of the driving member 20 and the moving member 30, so that the overall structure is more compact, suitable for narrow space, thereby reducing the size of the lifting frame 10 and reducing the cost. The detachable connection design improves the product versatility, can quickly adapt to different sizes or types of articles, while reducing the processing and installation cost, which is beneficial to wide application in the home environment.

[0035] Please refer to Figure 1 and Figure 2 The application further proposes that the frame 10 comprises a lower fixed plate 11 and a lead screw 12, the lower fixed plate 11 is used to be installed at a predetermined position, one end of the lead screw 12 is connected with the lower fixed plate 11, the moving member 30 is a nut, the nut is slidingly connected on the lead screw 12, and the driving member 20 is connected with one end of the lead screw 12, so that the nut is drivingly connected with the driving member 20 through the lead screw 12.

[0036] The lower fixed plate 11 refers to the installation base of the overall structure of the lifting frame, which can be formed by processing a metal plate to form a fixed support surface, and is fixed at a predetermined position by bolts or welding, for ensuring the stable installation of the lead screw 12 and the driving member 20. The lead screw 12 refers to a driving component with a threaded structure, which can be a metal rod with trapezoidal thread or ball screw, and the rotary motion can be converted into the linear motion of the nut, for transmitting the power of the driving member 20 and controlling the lifting trajectory of the moving member 30. The nut refers to a sliding component matched with the lead screw 12, which can be an internal threaded structure made of copper alloy or engineering plastic, and realizes the linear displacement along the axial direction through the rotation of the lead screw 12, for converting the rotary power of the driving member 20 into the linear lifting action of the moving frame 40.

[0037] The driving member 20 is coaxially connected with one end of the lead screw 12 through the output shaft, when the driving member 20 is started, the lead screw 12 rotates around its own axis, and the nut moves along the axial direction of the lead screw 12 under the meshing action of the thread. The moving frame 40 moves synchronously with the nut through the detachable connection structure, thereby driving the product to be lifted to realize the height adjustment in the vertical direction. Since the transmission structure of the lead screw 12 and the nut directly replaces the traditional guide rail, the frame 10 does not need to set an additional guide rail, and the compactness of the overall structure is improved.

[0038] Compared with the prior art, the traditional lifting frame relies on the guide rail to maintain the motion trajectory of the moving member 30, and the guide rail needs to occupy a large space and has a high processing cost. The linear guiding function of the moving member 30 is realized through the thread cooperation of the lead screw 12 and the nut in the present scheme, which not only saves the installation space and material consumption of the guide rail, but also simplifies the assembly process of the transmission structure.

[0039] By the technical scheme, the overall volume of the lifting frame is effectively reduced, the structural complexity is reduced, the machining and assembly costs of parts are reduced, the lifting frame can adapt to a limited space of a home environment, and the use and maintenance difficulty is reduced.

[0040] Please refer to Figure 1 and Figure 2 The present application further proposes that the frame body 10 further comprises an upper fixing plate 13 connected with the other end of the lead screw 12, used for installation at a preset position.

[0041] The upper fixing plate 13 refers to a support component fixed at the top end of the lead screw 12 and having a mounting structure, which can be realized by a metal plate with a through hole, and is fixed with the end of the lead screw 12 by bolt connection or welding, which functions to form a top fixed fulcrum of the lead screw 12 to avoid lateral deviation of the lead screw 12 during movement. The other end connection of the lead screw 12 refers to a rigid connection relationship between the top end of the lead screw 12 and the upper fixing plate 13, which can be realized by thread cooperation or interference assembly, for example, external threads are machined at the top end of the lead screw 12 and are screwed with the threaded holes of the upper fixing plate 13, which functions to establish a bidirectional constraint to ensure the axial positioning accuracy of the lead screw 12 during rotation. The preset position refers to a bearing plane where the lifting frame needs to be installed, which can be a wall surface or a support frame, for example, the upper fixing plate 13 is fixed to the surface of a concrete wall by expansion bolts, which functions to form a stable double-end fixed structure of the entire frame body 10.

[0042] When the driving member 20 drives the lead screw 12 to rotate, the nut moves along the axis direction of the lead screw 12, at this time, the upper fixing plate 13 forms a fixed constraint through the connection relationship with the top end of the lead screw 12, and together with the lower fixing plate 11, restricts the axial degree of freedom of the lead screw 12. In this process, the moving frame 40 realizes lifting through the linear displacement of the nut, and the existence of the upper fixing plate 13 makes the top end of the lead screw 12 always in a fixed state, thereby eliminating the swinging phenomenon caused by the top end of the lead screw 12 being suspended, and ensuring the stable movement of the moving frame 40 in the vertical direction. When the lifting frame needs to be installed in different scenes, the upper fixing plate 13 can adapt to the installation interfaces of different preset positions, for example, by providing multiple groups of mounting holes on the plate to adapt to wall embedded parts of different spacings.

[0043] Compared with the prior art, the traditional guide rail type lifting frame only relies on single side fixing, the top end of the lead screw 12 lacks constraint, and is prone to lateral vibration when the load changes, while the present scheme forms a double-end fixed structure by adding the upper fixing plate 13, so that the rotational movement of the lead screw 12 is completely restricted on the axis. The prior art needs to additionally set a guide rail to control the shaking, resulting in a complex structure and occupying space, while the present scheme uses the cooperative action of the upper fixing plate 13 and the lower fixing plate 11 to replace the function of the guide rail, simplifying the structure while realizing the same stability.

[0044] By the technical scheme, the transverse displacement of the lead screw 12 during operation is effectively eliminated, and the lifting track of the moving frame 40 is kept vertical precision; the double-end fixing mode is used to replace the traditional guide rail structure, the number of parts is reduced, and the overall volume is reduced, so that the lifting frame can be installed in a narrow space; the connection mode of the upper fixed plate 13 and the preset position is expandable, and can match various installation environments without redesigning the frame body 10 structure.

[0045] Please refer to Figure 1 and Figure 2 , the lower fixed plate 11 further comprises a vertical plate 11a and a horizontal plate 11b, the vertical plate 11a and the horizontal plate 11b are vertically arranged; the vertical plate 11a is used to be installed at a preset position, and the horizontal plate 11b is connected with the driving member 20.

[0046] The vertical plate 11a refers to a plate-shaped structure perpendicular to the mounting surface, which can be realized by cutting a metal plate, and its function is to enhance the connection stability of the lower fixed plate 11 and the wall or support through the vertical mounting surface. The horizontal plate 11b refers to a horizontally extending plate-shaped structure, which can be realized by welding or bolt fixing, and its function is to provide a stable installation basis for the driving member 20 through the horizontally extending support surface, and at the same time, the transmission direction of the driving member 20 is separated from the installation direction of the vertical plate 11a in space.

[0047] During installation, the vertical plate 11a is fixed to the surface of the wall or support frame to ensure the positioning accuracy of the lower fixed plate 11 in the vertical direction. The horizontal plate 11b and the vertical plate 11a form an overall structure through a right-angle connection, and the driving member 20 is installed on the surface of the horizontal plate 11b, so that the power output axis of the driving member 20 and the installation plane of the vertical plate 11a form an orthogonal relationship. This split structure design enables the lower fixed plate 11 to disperse the horizontal stress when bearing the working load of the driving member 20 through the horizontal plate 11b, and at the same time, absorbs the vertical vibration through the vertical plate 11a, thereby avoiding the problem of additional reinforcement measures required by the traditional integrated base.

[0048] Compared with the prior art, the lower fixed structure of the traditional guide rail type lifting frame usually adopts single plate welding or casting forming, which needs to reserve guide rail installation space, resulting in increased volume. The present application separates the installation position of the driving member 20 from the fixed base through the right-angle split design of the vertical plate 11a and the horizontal plate 11b, which not only saves longitudinal space but also simplifies the processing procedure. This design does not need to process guide rail grooves on the base, but can be directly assembled by plate combination, which significantly reduces the production complexity.

[0049] By the technical scheme, the overall thickness of the lower fixing structure is effectively reduced, so that the lower fixing structure can adapt to the installation requirement in a narrow space. The split plate structure reduces the material cost and processing loss while ensuring the bearing strength, facilitates adjustment of the length of the transverse plate 11b according to the size of the driving member 20, and enhances the adaptability of the product.

[0050] Please refer to Figure 1 and Figure 2 The upper fixing plate 13 further includes a main plate 13a and a top plate 13b. The top plate 13b is connected to the top of the main plate 13a, and the top plate 13b is connected to the other end of the screw rod 12. The main plate 13a is connected to the moving frame 40.

[0051] The main plate 13a is a main force component of the upper fixing plate 13, which can be realized by a stamping formed metal plate, and is used to provide a plane support function. The top plate 13b is a plate-shaped structure perpendicular to the main plate 13a, which can be connected to the main plate 13a by welding or bolt fixing, and is used to disperse the axial load transmitted by the screw rod 12. The main plate 13a is connected to the moving frame 40, which means that the two form a detachable mechanical connection, which can be realized by a buckle or bolt fastening method, and facilitates the disassembly and maintenance of the moving frame 40.

[0052] After the top plate 13b is connected to the end of the screw rod 12, the rotational movement of the screw rod 12 can be converted into the vertical displacement of the moving frame 40. At the same time, a stable triangular support structure is formed by the vertical connection of the top plate 13b and the main plate 13a, which effectively disperses the load transmitted by the screw rod 12. The detachable connection between the main plate 13a and the moving frame 40 allows the moving frame 40 to be replaced without disassembling the entire lifting frame. The planar structure of the main plate 13a can provide a uniform bearing surface for the moving frame 40, avoiding local stress concentration. During operation, the rigid connection between the top plate 13b and the main plate 13a can suppress the vibration transmission generated during the rotation of the screw rod 12, thereby improving the stability of the lifting process.

[0053] Compared with the prior art, the upper fixing plate 13 of the traditional lifting frame usually adopts an integral casting structure, which not only has a large weight but also has low installation positioning accuracy. The split main plate 13a and top plate 13b structure of the present application not only ensures the connection accuracy but also reduces the overall weight. In the prior art, the moving frame 40 and the fixing plate are usually fixed by welding, which makes maintenance difficult. The detachable connection method of the present application significantly improves the convenience of equipment maintenance.

[0054] By the technical scheme, the lightweight and modular design of the top support structure of the lifting frame is realized, the assembly process is simplified while the bearing capacity is ensured, and the production manufacturing cost is effectively reduced. The combined structure of the top plate 13b and the main plate 13a can adapt to the installation requirements of different specifications of the lead screw 12, and the flexibility of equipment assembly is enhanced. The detachable connection mode of the moving frame 40 and the main plate 13a facilitates quick replacement of adaptive components for different sizes of products, and improves the utilization rate of the equipment.

[0055] Please refer to Figure 1 and Figure 2 , the application further proposes that the two sides of the moving frame 40 are each provided with a U-shaped groove, and the U-shaped groove and the main plate 13a form an installation site.

[0056] Among them, the U-shaped groove refers to a groove structure with an opening facing upward, which can be cut and processed from metal or plastic materials, and is used to cooperate with the main plate 13a to form a closed installation space. The installation site refers to a fixed area enclosed by the U-shaped groove and the main plate 13a, which can be realized by adjusting the size of the U-shaped groove and the positional relationship of the main plate 13a, and is used to accommodate and fix the retaining block 50. The retaining block 50 refers to a support component arranged in the installation site, which can be molded from rubber or nylon material, and is connected to the moving frame 40 by being embedded in the installation site, and is used to provide limiting and buffering effects.

[0057] Specifically, the opening direction of the U-shaped groove on both sides of the moving frame 40 is perpendicular to the extension direction of the main plate 13a. When the moving frame 40 is assembled with the main plate 13a, the inner wall of the U-shaped groove is attached to the outer surface of the main plate 13a to form an annular installation space. The retaining block 50 is fixed in the installation site by pressing or clamping, and its outer contour matches the shape of the installation site, thereby limiting the transverse displacement of the moving frame 40 relative to the main plate 13a. During lifting, the moving frame 40 moves in the vertical direction, and the retaining block 50 resists the shaking of external load through the friction generated by the contact surface with the main plate 13a, and at the same time absorbs vibration energy through elastic deformation.

[0058] Compared with the prior art, the existing lifting frame usually relies on the cooperation of guide rails and sliding blocks to realize guiding and limiting, which requires additional installation of guide rail structures and regular lubrication and maintenance, resulting in increased volume and cost. The present scheme directly encloses the installation site by the U-shaped groove and the main plate 13a, and uses the retaining block 50 to realize the limiting function, which eliminates the guide rail structure and simplifies the assembly steps, while the elastic material properties of the retaining block 50 reduce the maintenance frequency.

[0059] By the technical scheme, the stable lifting of the moving frame 40 can be realized without relying on a guide rail, the overall volume and the number of parts of the lifting frame are reduced, the production and maintenance costs are reduced, the stability and the anti-vibration capability of the lifting process are improved through the elastic contact of the retaining block 50.

[0060] Please refer to Figure 1 and Figure 2 The application further provides a lifting frame, which comprises an outer frame 41 and at least two hanging bars 42, the two hanging bars 42 are detachably connected to the outer frame 41, the outer frame 41 is detachably connected to the moving piece 30, the hanging bar 42 is used for mounting electronic products, and the hanging bar 42 is provided with a plurality of waist-shaped holes.

[0061] The outer frame 41 refers to a basic frame structure for bearing the hanging bar 42, which can be formed by welding metal profiles and is detachably connected to the moving piece 30 through bolts. This structure is convenient for disassembly and maintenance and is suitable for different installation scenes. The hanging bar 42 refers to a linear supporting part for bearing electronic products, which can be processed by using aluminum alloy profiles and is fixed on the outer frame 41 through T-shaped grooves and locking bolts. The spacing can be adjusted to adapt to electronic products of different sizes. The waist-shaped hole refers to a through hole structure with a semicircular shape at both ends in the length direction, which can be processed by using a numerical control punching process. The mounting bolt can be adjusted within a certain range, and the position of the electronic product can be finely adjusted.

[0062] Specifically, when the installation layout of the electronic product needs to be adjusted, the outer frame 41 can be first detached from the moving piece 30, the connecting bolts of the hanging bar 42 and the outer frame 41 are loosened, and then the spacing of the hanging bar 42 is repositioned. The waist-shaped hole on the hanging bar 42 allows the electronic product to be fixed by bolts with washers in multiple points, for example, when a liquid crystal display screen is installed, the suspension position can be adjusted according to the size of the screen by selecting adjacent waist-shaped holes. The detachable connection between the outer frame 41 and the moving piece 30 eliminates the traditional guide rail structure, effectively reducing the overall thickness of the lifting frame.

[0063] Compared with the prior art, the traditional guide rail type lifting frame needs to set a complex guide rail to maintain the stability of the moving frame 40, while the present application realizes the installation mode without a guide rail through the modular combination of the outer frame 41 and the hanging bar 42. In the prior art, the fixed position of the electronic product is not adjustable, and the present application uses the sliding characteristics of the waist-shaped hole to make the installation position adjustable, solving the problem of poor adaptability of the traditional structure.

[0064] Through the above technical scheme, the present application realizes the flexible adjustment of the installation position of the electronic product, can adapt to the fixing requirements of products of different specifications, and reduces the equipment maintenance difficulty through the detachable modular design. The separated structure of the hanging bar 42 and the outer frame 41 avoids the space occupation problem of the traditional integral support, so that the lifting frame can be detached and stored in the non-use state to save space.

[0065] Referring to Figure 1 and Figure 2 , the application further proposes that the hanging strip 42 is provided with a plurality of waist-shaped holes for detachable connection with the electronic product.

[0066] Among them, the waist-shaped hole refers to an elliptical through hole opened along the length direction of the hanging strip 42, which can be realized by stamping process or laser cutting process, and the long axis direction is consistent with the extension direction of the hanging strip 42, which is used to accommodate fasteners of different sizes. Among them, detachable connection refers to assembly through the cooperation of bolts and waist-shaped holes, which can be realized by bolt assembly with locking nuts, and by adjusting the installation position of the bolt in the waist-shaped hole, it can adapt to the installation requirements of electronic products of different specifications.

[0067] Specifically, when it is necessary to fix the electronic product, the bolt assembly can be inserted into the waist-shaped hole by selecting the appropriate position, and the mounting hole of the electronic product is aligned with the waist-shaped hole to complete the locking. Due to the length direction extension characteristic of the waist-shaped hole, the bolt can be continuously adjusted in the hole, and it is not necessary to pre-set fixed pitch mounting hole positions on the hanging strip 42. When the electronic product needs to be replaced or maintained, it only needs to loosen the locking nut to release the connection, and the assembly relationship between the hanging strip 42 and the outer frame 41 remains stable.

[0068] Compared with the prior art, the traditional lifting frame usually adopts fixed-pitch circular mounting holes, which limits the installation position of the electronic product to the hole distribution, and additional adaptive support or adjustment of the overall structure is required. The continuous installation channel formed by the waist-shaped hole enables the same hanging strip 42 to be compatible with electronic products of different specifications, without the need to change the main structure of the lifting frame to complete the adaptive installation of various products.

[0069] Through the above technical scheme, the application realizes the adjustability of the installation position of the electronic product, effectively reduces the frequency of replacement of parts due to changes in product specifications, and at the same time, through the standardized structure of the hanging strip 42, the production cost is reduced, and the stable running state of the lifting frame when carrying the electronic product is ensured.

[0070] Referring to Figure 1 and Figure 2 , the application further proposes that the mobile frame 40 comprises an outer frame 41 and at least two hanging strips 42, the two hanging strips 42 are detachably connected to the outer frame 41, the outer frame 41 is detachably connected to the moving piece 30, the hanging strip 42 is used to install the electronic product, the hanging strip 42 is provided with a plurality of waist-shaped holes, the waist-shaped holes are used for detachable connection with the electronic product, wherein the hanging strip 42 is also provided with a plurality of positioning holes, the positioning holes are distributed at intervals along the length direction of the hanging strip 42, the positioning holes are arranged in a staggered manner with the waist-shaped holes, the outer frame 41 is provided with an adjusting bolt at a position corresponding to the positioning hole, and the adjusting bolt is threadedly connected with the outer frame 41 after penetrating through the positioning hole.

[0071] Specifically, the hanging strip 42 is in sliding fit with the mounting boss at the bottom of the electronic product through the waist-shaped hole, allowing the electronic product to adjust the mounting position along the length direction of the waist-shaped hole. When it is necessary to fix the electronic product, the adjusting bolt passes through the positioning hole and is in threaded connection with the outer frame 41, and the hanging strip 42 is pressed against the surface of the outer frame 41 by screwing the bolt, so as to limit the relative displacement of the hanging strip 42 and the electronic product. The detachable connection of the hanging strip 42 and the outer frame 41 can be realized through a buckle structure, for example, the elastic clamping jaws are arranged at the edge of the outer frame 41, and the corresponding clamping grooves are arranged at the end of the hanging strip 42.

[0072] In some specific embodiments, the positioning holes and the waist-shaped holes can be arranged in an interleaved manner, for example, one positioning hole is arranged every two waist-shaped holes. The head of the adjusting bolt can be configured with a hexagonal groove, facilitating the fastening operation by using a hexagonal wrench. The contact surface of the hanging strip 42 and the outer frame 41 can be additionally provided with anti-skid lines, such as knurling or rubber pads, to enhance the friction locking effect.

[0073] Compared with the prior art, the hanging strip 42 of the existing lifting frame is usually fixed by welding or single bolt locking, which cannot realize multi-position adjustment and has low disassembly and assembly efficiency. The present scheme realizes the discrete positioning capability of the hanging strip 42 through the cooperation of the positioning hole and the adjusting bolt, while retaining the continuous adjustment function of the waist-shaped hole, thereby expanding the installation adaptability on the premise of ensuring stability. Compared with the way of adding guide rails, this structure does not need complex guide components, but directly realizes rigid fixation by using threaded fastening.

[0074] Through the above technical scheme, the present application can realize both continuous adjustment of the mounting position of the electronic product within the range of the waist-shaped hole and discrete precise positioning at the position of the positioning hole, thereby solving the problem that the adjustment accuracy and operation convenience of the traditional lifting frame are difficult to be considered simultaneously. The cooperation of the adjusting bolt and the positioning hole forms a double locking mechanism, avoiding the displacement of the electronic product in a vibrating environment, and simplifying the disassembly and assembly process, so that the operator can only tighten or loosen the bolt to complete the position adjustment.

[0075] Please refer to Figure 1 and Figure 2 The present application further proposes that the hanging strip 42 is provided with a plurality of waist-shaped holes, and the waist-shaped holes are used for detachable connection with the electronic product.

[0076] The hanging strip 42 is detachably connected to the outer frame 41 and can be made of metal or high-strength plastic material, and has mounting holes on the surface to fix the electronic product. The structure can adapt to electronic products of different sizes by adjusting the relative position of the hanging strip 42 and the outer frame 41, and reduces the structural complexity. The waist-shaped hole is a long circular through hole extending along the length direction, which can be formed by stamping or cutting process, and the long axis direction is consistent with the extension direction of the hanging strip 42. The design allows the mounting bolt to slide in the hole and then be locked, realizing the horizontal position adjustment of the electronic product, and avoiding the structural interference caused by the size difference of the product.

[0077] Specifically, the hanging strip 42 is adjustably fixed by the waist-shaped hole and the connecting piece of the electronic product. The connecting piece can be moved to the target position along the length direction of the waist-shaped hole and then locked. After the outer frame 41 is connected with the moving piece 30, the driving piece 20 drives the moving frame 40 to rise and fall as a whole through the lead screw 12, and the electronic product on the hanging strip 42 moves synchronously in the rising and falling process. Since the waist-shaped hole provides a horizontal adjustment space, the same hanging strip 42 can adapt to electronic products of different widths without the need to replace special hanging pieces for different products.

[0078] Compared with the prior art, the traditional guide rail type lifting frame needs to set a horizontal guide rail adjustment mechanism to realize product adaptation, which increases the overall thickness and the number of parts. The present scheme replaces the horizontal guide rail mechanism with the waist-shaped hole, which eliminates the space occupied by the guide rail while ensuring the adjustability of the mounting position.

[0079] Through the above technical scheme, the present application can simplify the horizontal adjustment structure while maintaining the lifting function, reduce the material cost and assembly difficulty. The multiple mounting points provided by the waist-shaped hole enable a single hanging strip 42 to adapt to electronic products of multiple specifications, reducing the replacement frequency of special accessories and improving the utilization rate of the equipment. At the same time, after removing the guide rail structure, the overall size of the lifting frame is more compact, which is convenient for installation and use in a small space.

[0080] The above is only an exemplary embodiment of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
