Description

Technical Field

[0001] This utility model belongs to the field of pull-out table technology, and in particular relates to a square 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 a square 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 square pull-out guide rail of the pull-out table of this utility model is as follows:

[0006] A square pull-out guide rail for a pull-out table includes a table frame one and a table frame two, which are respectively fixedly connected to two tabletops. The table frame one and table frame two are arranged side by side opposite each other. The table frame one and table frame two are characterized in that each of the opposite sides of the table frame one and table frame two is provided with a slide rail and a pulley, and the pulley on one side cooperates with the slide rail on the other side, and the two sets of slide rails and pulleys are nested together.

[0007] Furthermore, a slide rail is provided on the upper end of the side of the table frame facing the second side of the table frame. The slide rail is an embedded groove with raised guide strips at both ends. The upper end of the side of the second side of the table frame facing the first side of the table frame has multiple pulley mounting holes arranged at the same height. Multiple pulleys are rotatably installed in the pulley mounting holes. The pulleys are nested in the slide rail and limited by the guide strips. The pulleys can slide back and forth in the slide rail.

[0008] Furthermore, the first guide bar is semi-circular, and the first pulley is semi-concave, which matches the shape of the first guide bar.

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

[0010] Furthermore, the lower end of the side of the table frame facing the second table frame is provided with a plurality of pulley mounting holes of equal height, and a plurality of pulleys are rotatably installed in the pulley mounting holes. The lower end of the side of the second table frame facing the first table frame is provided with a slide rail, which is an embedded groove with protruding guide strips at both ends of the groove. The pulleys are nested in the slide rail and are limited by the guide strips, allowing the pulleys to slide back and forth within the slide rail.

[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.

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

[0013] Furthermore, the first and second table frame frames are square frames with a hollow interior and one or more reinforcing ribs inside to increase the frame's sturdiness.

[0014] Furthermore, the table frame one and table frame two achieve relative sliding through a nested structure of slide rails and pulleys, thereby realizing the telescopic function between the two tabletops.

[0015] The square pull-out guide rail of the pull-out table of this utility model has the following advantages:

[0016] Strong structural stability: By setting slide rails and pulleys on opposite sides of table frame one and table frame two, and with the two sets of slide rails and pulleys nested together, the connection stability of the guide rails is enhanced, avoiding the problem of traditional single-sided pulleys easily slipping off.

[0017] Smooth pull-out: The combined design of the slide rails and pulleys makes the pull-out process smoother, reducing jamming or sticking and improving the user experience.

[0018] To prevent slippage: The guide bar of the slide rail is designed in a semi-circular arc shape, and the circumference of the pulley is a semi-concave arc shape. The two shapes are matched to each other, which can effectively prevent the pulley from slipping off the slide rail during the sliding process, ensuring the reliability and durability of the guide rail.

[0019] Uniform force distribution: The number of pulleys and slide rails is set to multiple (e.g., multiple), and they are evenly distributed, which makes the force distribution more uniform during the pulling process, reduces local wear, and extends the service life of the guide rails.

[0020] Sturdy frame: The first and second table frame frames adopt a square frame design with internal reinforcing ribs, which increases the sturdiness of the frame. At the same time, the hollow internal design reduces the overall weight and lowers the cost.

[0021] Wide applicability: This square pull-out rail has a simple structure and is suitable for various scenarios, such as small apartments, offices, and conference rooms. It can flexibly adjust the desktop size according to needs, saving space.

[0022] Easy to maintain: Due to the reasonable design of the pulleys and rails, maintenance and replacement are relatively convenient, reducing the difficulty and cost of later maintenance.

[0023] In summary, the square pull-out guide rail of this utility model has the advantages of stable structure, smooth pull-out, anti-slip, uniform force distribution, sturdy frame, wide applicability and easy maintenance. It can effectively solve the problems of easy jamming and slippage of traditional pull-out table guide rails, and improve the performance and user experience of pull-out tables.
