Description

Technical Field

[0001] This utility model belongs to the field of pull-out table technology, and in particular relates to an arc-shaped pull-out guide rail for a pull-out table. Background Technology

[0002] A pull-out table is a type of furniture with an extendable function, typically used to save space or adapt to different usage needs. The design of a pull-out table aims to solve the problems of traditional tables being space-consuming and having limited functionality. Through its extendable structure, users can adjust the desktop size as needed, making it suitable for various scenarios such as small apartments, offices, and meeting rooms. The core design of a pull-out table includes the extension mechanism: it typically uses slide rails and gears to achieve the extension and retraction of the desktop. Gear structures are not smooth during the pull-out process and are prone to jamming, while slide rail structures generally have pulleys on only one side, which can easily disengage during the pull-out process, rendering the table unusable.

[0003] Designing a guide rail that allows for smooth sliding and prevents slippage or jamming is a problem that needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to provide an arc-shaped pull-out guide rail for a pull-out table to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the specific technical solution of the arc-shaped pull-out guide rail of the pull-out table of this utility model is as follows:

[0006] An arc-shaped pull-out guide rail for a pull-out table includes a guide rail one and a guide rail two. The guide rail two is nested within the guide rail one and can slide telescopically within the guide rail one. The guide rail one serves as the table frame of the main desktop and is fixedly connected to the main desktop. The guide rail two serves as the table frame of the extendable desktop and can act as a support frame for the extended desktop when it is extended. The inner sides of the guide rail one and the guide rail two are right-angled and are both 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 the guide rail one and the guide rail two are arc-shaped.

[0007] Furthermore, the upper inner side of the inner wall of the first guide rail has a slide rail, which is an embedded groove with protruding guide bars at both ends of the groove; the side of the second guide rail facing the slide rail has multiple pulley mounting holes of equal height, and multiple pulleys are rotatably installed in the pulley mounting holes. The pulleys are nested in the slide rail and are limited by the guide bars.

[0008] Furthermore, the guide bar is semi-circular, and the pulley is semi-concave, which matches the shape of the guide bar. The pulley can slide back and forth within the slide rail.

[0009] Furthermore, the pulleys include multiple pulleys, each distributed at equal intervals.

[0010] Furthermore, the lower inner wall of the guide rail has an embedded fixing groove, in which a fixing strip is fixedly installed. The fixing strip has one or more pulley mounting holes, on which a pulley is rotatably installed. The side of the guide rail facing the fixing groove has a slide rail, which is an embedded groove. The upper and lower ends of the groove have protruding guide strips. The pulley is nested in the slide rail and is limited by the guide strips.

[0011] Furthermore, the second guide bar is semi-circular, and the second pulley is semi-concave, which matches the shape of the second guide bar. The second pulley can slide back and forth within the second slide rail to prevent it from coming off.

[0012] Furthermore, the second pulley comprises multiple pulleys, each distributed at equal intervals.

[0013] Furthermore, the first and second guide rails are hollow frames with one or more reinforcing ribs inside to enhance the frame's sturdiness.

[0014] The pull-out guide rail of the pull-out table of this utility model has the following advantages:

[0015] 1. Smooth pull-out and easy operation: The nested design of guide rail one and guide rail two, combined with the cooperation of pulleys and rails, makes the pull-out process smoother and reduces the phenomenon of jamming and stuck. Users can easily realize the extension and retraction operation of the desktop.

[0016] 2. Stable structure to prevent slippage: Multiple sets of pulleys and rails are provided on the inner side of guide rail one and guide rail two, and the shapes of the pulleys and rails are compatible with each other (semi-circular arc and semi-concave arc), which effectively prevents the pulleys from coming off during sliding and enhances the stability and durability of the guide rails.

[0017] 3. Rounded design for smoother sliding: The outer sides of guide rails one and two feature a rounded design, which not only improves the streamlined shape of the table frame but also makes the sliding process smoother, reduces frictional resistance, and further enhances the user experience.

[0018] 4. Multiple pulleys distributed for uniform force: Both pulley one and pulley two adopt a design with multiple equally spaced pulleys, which makes the force more uniform during the pulling process, reduces local wear, and extends the service life of the guide rail.

[0019] 5. Lightweight design to reduce costs: Guide rail one and guide rail two adopt a hollow frame structure with internal reinforcing ribs, which not only ensures the frame's sturdiness but also reduces the overall weight, lowers material costs, and facilitates production and transportation.

[0020] 6. Easy to maintain and replace: The modular design of the pulleys and rails makes maintenance and replacement more convenient. Users can easily replace damaged parts as needed, extending the product's service life.

[0021] In summary, the arc-shaped pull-out guide rail of this utility model not only improves the user experience of the pull-out table, but also enhances the stability and durability of the structure, and has broad application prospects and market value. Attached Figure Description
