Description

Technical Field

[0001] This utility model belongs to the field of pull-out table technology, and in particular relates to a pull-out table that extends and retracts on both sides. Background Technology

[0002] Existing pull-out desks typically use a single-sided extension structure, extending the desktop via guide rails. However, their functionality is relatively limited and cannot meet users' needs for more desktop space. While some double-sided pull-out desks can extend to both sides, their structural design has the following problems:

[0003] Insufficient stability: The guide rails of traditional pull-out desks are mostly designed in a straight line, which makes them prone to wobbling during extension and retraction. Especially when fully extended, the load-bearing capacity and stability of the desktop are poor.

[0004] Complex operation: Some double-sided telescopic tables have complex structures, are cumbersome to operate, and provide a poor user experience.

[0005] Inconvenient storage: When the extended section is retracted, it often takes up extra space or cannot be completely hidden under the main tabletop, affecting aesthetics and space utilization.

[0006] Furthermore, existing technologies lack a dual-sided telescopic pull-out table that can simultaneously achieve smooth pull-out, stable support, and convenient storage. Therefore, there is an urgent need for a dual-sided telescopic pull-out table with a reasonable structure, simple operation, and strong stability to solve the aforementioned technical problems. Utility Model Content

[0007] The purpose of this utility model is to provide a pull-out table that extends and retracts on both sides to solve the above-mentioned technical problems.

[0008] To achieve the above objectives, the specific technical solution of this utility model for a pull-out table with retractable sides is as follows:

[0009] A pull-out table with retractable sides includes a main body, a telescopic part, and an extension part. The main body includes a main tabletop, a main table frame, and table legs. The main tabletop is mounted on the main table frame, and the table legs are mounted below the main table frame. The telescopic part is located at both ends of the main tabletop and can extend and retract along both ends of the main tabletop. The telescopic part includes a telescopic tabletop and a telescopic table frame. The telescopic tabletop is fixedly mounted on the upper front end of the telescopic table frame, and the telescopic table frame and the two sides of the main table frame are slidably connected via guide rails. The extension part is connected to the telescopic part and includes an extension tabletop and an extension frame. One end of the extension frame is fixedly connected to the front end of the telescopic table frame, and the other end is slidably connected to the inner sides of the main table frame. The extension tabletop is fixedly mounted on the extension frame and is positioned below the main tabletop when retracted. When the telescopic part extends, it can flip out and connect with the main tabletop.

[0010] Furthermore, the guide rail is an arc-shaped pull-out guide rail, including a first guide rail and a second guide rail. The second guide rail is nested inside the first guide rail and slides within the first guide rail. The first guide rail serves as the side frame of the main table frame and is fixedly connected to the main tabletop. The second guide rail serves as the side frame of the telescopic table frame.

[0011] Furthermore, the inner sides of the first and second guide rails are right-angled and both are equipped with pulleys and rails, with the pulley on one side cooperating with the rail on the other side, and the two sets of rails and pulleys nested together; the outer sides of the first and second guide rails are arc-shaped.

[0012] Furthermore, the upper inner side of the first guide rail tube wall has a first slide rail, which is an embedded groove with protruding first guide bars at both ends of the groove; the side of the second guide rail facing the first slide rail has multiple first pulley mounting holes arranged at equal heights, and multiple first pulleys are rotatably installed in the first pulley mounting holes. The first pulleys are nested in the first slide rail and are limited by the first guide bars.

[0013] Furthermore, the first pulley comprises multiple pulleys, each distributed at equal intervals.

[0014] Furthermore, the lower inner side of the first guide rail tube wall has an embedded fixing groove, in which a fixing strip is fixedly installed. The fixing strip has one or more second pulley mounting holes, and a second pulley is rotatably installed in the second pulley mounting holes. The side of the second guide rail facing the fixing groove has a second slide rail, which is an embedded groove. The upper and lower ends of the groove have protruding second guide strips. The second pulley is nested in the second slide rail and is limited by the second guide strips.

[0015] Furthermore, the second pulley comprises multiple pulleys, each distributed at equal intervals.

[0016] Furthermore, a third slide rail is installed on the outer side of the first guide rail, and the extension frame is a square frame with third pulleys on both ends. The extension frame slides within the third slide rail via the third pulleys.

[0017] Furthermore, the extension frame is fixedly mounted with bearing seats at the front and rear, and a rotating shaft is mounted on the bearing seats. The extension table includes two folding panels: a first folding panel and a second folding panel, which are hinged together. The bottom of the first folding panel is rotatably connected to the rotating shaft through an L-shaped connector. The extension frame has a support rod for supporting the folding panels in the retracted state.

[0018] Furthermore, during retraction, the second folding plate flips and folds onto the first folding plate, and the two folding plates flip along the pivot, so that the bottom of the first folding plate faces upward and is below the plane of the main tabletop; during extension, the telescopic part is pulled to drive the extension part to extend from the bottom of the main tabletop, flips the folding plate and lays it flat above the telescopic table frame, and pushes the telescopic part to align the extension part with the main tabletop.

[0019] The pull-out table that extends and retracts on both sides according to this utility model has the following advantages:

[0020] 1. Flexible retractable design on both sides, significantly improving space utilization.

[0021] With its symmetrical telescopic structure, users can flexibly adjust the desktop length according to their actual needs, achieving the dual functions of small-size storage and large-area expansion, perfectly adapting to different usage scenarios.

[0022] 2. The arc-shaped guide rail system ensures smooth and stable sliding.

[0023] The nested arc-shaped pull-out guide rails (guide rail one and guide rail two) combined with multiple sets of pulley-rail structures not only ensure the smoothness of the extension and retraction process, but also effectively prevent derailment through the precise matching of the semi-circular arc guide strips and grooves, significantly improving load-bearing stability.

[0024] 3. Concealed extension design for convenient and aesthetically pleasing storage.

[0025] The extension section features a foldable tabletop structure. When retracted, it flips over via a hinge and is completely hidden under the main tabletop, requiring no disassembly or additional space occupation, keeping the desktop appearance clean. Meanwhile, the support rod design ensures stability when folded.

[0026] 4. Integrated linkage structure, simple and efficient operation.

[0027] The telescopic and extension sections are linked by the frame and guide rails, allowing the telescopic and extension panels to be unfolded simultaneously with a single pull. After flipping, they automatically align with the desktop, enabling rapid expansion with a simple "pull and flip," significantly improving ease of use.

[0028] 5. Modular component design, low maintenance cost

[0029] The pulleys, rails and other vulnerable parts adopt a standardized modular design, which can be replaced independently, extending the product's service life and reducing maintenance difficulty and cost.

[0030] 6. Optimized structural strength, suitable for a wide range of scenarios

[0031] The main table frame and the telescopic table frame are supported at multiple points by a double pulley system (pulley one and pulley two), and are further fixed by the slide rail three of the extension frame, so that the unfolded table has excellent torsional resistance and load-bearing capacity, meeting the needs of multiple scenarios such as office and catering.

[0032] In summary, this utility model, through its innovative mechanical structure and user-friendly design, significantly outperforms traditional pull-out table products in terms of functionality, stability, and user experience. Attached Figure Description

[0044] The inner sides of guide rail 1 (21) and guide rail 2 (51) are right-angled and both are equipped with pulleys and rails. The pulleys on one side cooperate with the rails on the other side, and the two sets of rails and pulleys are nested together. The outer sides of guide rail 1 (21) and guide rail 2 (51) are arc-shaped. The arc-shaped design makes the entire pull-out process smoother.

[0045] The upper inner side of the inner wall of guide rail 21 has a slide rail 211, which is an embedded groove. The upper and lower ends of the groove have protruding guide bars 2111. The side of guide rail 2 51 facing slide rail 211 has multiple pulley mounting holes 511 of equal height. Multiple pulleys 512 are rotatably installed in the pulley mounting holes 511. The pulleys 512 are nested in slide rail 211 and are limited by the guide bars 2111. The guide bars 2111 are semi-circular arc-shaped, and the circumference of the pulleys 512 is semi-concave arc-shaped, which matches the shape of the guide bars 2111. The pulleys 512 can slide back and forth in slide rail 211 to prevent them from falling out.

[0046] Preferably, pulley 512 comprises a plurality of pulleys, each distributed at equal intervals.

[0047] The lower inner wall of guide rail 21 has an embedded fixing groove 212. A fixing strip 213 is fixedly installed in the fixing groove 212. The fixing strip 213 has one or more pulley mounting holes 2131. A pulley 214 is rotatably installed on the pulley mounting hole 2131. The side of guide rail 51 facing the fixing groove 212 has a slide rail 513. The slide rail 513 is an embedded groove. The upper and lower ends of the groove have protruding guide strips 5131. The pulley 214 is nested in the slide rail 513 and is limited by the guide strips 5131. The guide strips 5131 are semi-circular arc-shaped, and the circumference of the pulley 214 is semi-concave arc-shaped, which matches the shape of the guide strips 5131. The pulley 214 can slide back and forth in the slide rail 513 to prevent it from falling out.

[0048] Preferably, pulley 214 comprises multiple pulleys, each distributed at equal intervals.

[0049] The extension section includes an extension tabletop 6 and an extension frame 7. One end of the extension frame 7 is fixedly connected to the front end of the telescopic table frame 5, and the other end is slidably connected to the inner sides of the main table frame 2 on both sides, extending and retracting with the telescopic section. The extension tabletop 6 is fixedly installed on the extension frame 7 and moves with the extension frame 7.

[0050] like Figure 5 As shown, a slide rail 215 is installed on the outer side of the guide rail 21. The extension frame 7 is a square frame with pulleys 71 on both sides of its ends. The extension frame 7 slides within the slide rail 215 via the pulleys 71.

[0051] like Figure 6 As shown, the extension frame 7 is fixedly installed with bearing seats 72 at the front and rear, and a rotating shaft 73 is installed on the bearing seats 72. The extension table 6 includes two folding plates: folding plate one 61 and folding plate two 62. Folding plate one 61 and folding plate two 62 are hinged together and can be flipped and folded. The bottom of folding plate one 61 is rotatably connected to the rotating shaft 73 through an L-shaped connector 63. The extension frame 7 has a support rod 74 for supporting the folding plate in the retracted state.

[0052] When retracting, folding plate 2 62 is flipped and folded onto folding plate 1 61. Then, the two folding plates are flipped together along the pivot 73, so that the bottom of folding plate 1 61 faces upward, reducing its height and placing it below the plane of the main table 1. Support rod 74 is used to support the folded plates. At this time, pushing the telescopic part can retract the extension part under the main table 1.

[0053] When extending, first pull the telescopic part to extend the extension part from the bottom of the main tabletop 1. Then flip the entire folding board and open the two folding boards, laying them flat on top of the telescopic table frame 5. Then push the telescopic part inward to align the extension part with the main tabletop 1, thus extending the tabletop.
