Double-opening two-section slide rail

Abstract

This utility model relates to a double-opening, two-section slide rail, comprising a slide rail assembly, a first slide rail, and a second slide rail. The first slide rail is slidably disposed within the inner cavity of the slide rail assembly, and the second slide rail is slidably disposed within the inner cavity of the first slide rail. A buffer mechanism is connected to the right side of the second slide rail. The buffer mechanism includes a hollow shell, with a first trapezoidal block slidably connected to the right side of the hollow shell. Second trapezoidal blocks are slidably connected to both ends of the inner cavity of the hollow shell. A rubber plate is connected to the ends of the two second trapezoidal blocks that are furthest apart. A first spring connects the first trapezoidal block to the hollow shell, and a T-shaped block is connected to the other end of the first trapezoidal block. A locking groove is formed at the top of the second slide rail, and a bolt is threaded into the inner cavity of the locking groove. When the T-shaped block is impacted, the double-opening, two-section slide rail automatically decelerates the sliding speed of the second slide rail, thereby preventing the second slide rail from colliding with external objects and causing damage.

Description

Technical Field

[0001] This utility model relates to the field of slide rails, specifically to a double-opening two-section slide rail. Background Technology

[0002] Double-section, two-part slide rails, also known as guide rails or slide tracks, are mechanical components used to achieve linear motion. They allow one component to move smoothly along a straight line on top of another through rolling, sliding, or other methods. Slide rails are widely used in various mechanical equipment, furniture, electronic products, and transportation vehicles, and are an indispensable basic component in modern industry and daily life.

[0003] When sliding rails are used on the exterior of doors and windows, after the doors and windows are closed forcefully, the track blocks inside the sliding rail will slide rapidly in the inner cavity of the sliding rail due to inertia. Eventually, the outermost end of the sliding rail will impact the track blocks, which will damage the track blocks, ultimately reducing the overall service life of the sliding rail and increasing the noise of the device during use. Utility Model Content

[0004] The purpose of this utility model is to solve the above defects and provide a double-opening two-section slide rail, which solves the technical problems of existing technology where impact force will damage the track block, ultimately reducing the overall service life of the slide rail, and increasing the noise hazards caused by the device during use.

[0005] The purpose of this utility model is achieved through the following method: a double-opening two-section slide rail, including a slide rail assembly, a first slide rail, and a second slide rail. The first slide rail is slidably disposed in the inner cavity of the slide rail assembly, and the second slide rail is slidably disposed in the inner cavity of the first slide rail. A buffer mechanism is connected to the right side of the second slide rail. The buffer mechanism includes a hollow shell. A first trapezoidal block is slidably connected to the right side of the hollow shell. Second trapezoidal blocks are slidably connected to both ends of the inner cavity of the hollow shell. A rubber plate is connected to one end of the two second trapezoidal blocks that are far apart from each other. A first spring is connected between the first trapezoidal block and the hollow shell, and a T-shaped block is connected to the other end of the first trapezoidal block.

[0006] Furthermore, the inner cavity of the slide rail assembly is evenly distributed with balls on both sides, and the inner cavity of the slide rail assembly is provided with ball grooves that are adapted to the balls. The balls can reduce the coefficient of friction between the first slide rail and the slide rail assembly, thereby improving the smoothness of the first slide rail movement.

[0007] Furthermore, the slide rail assembly is connected to both the left and right ends of its bottom with an assembly frame. The bottom of the assembly frame has an installation groove, which can be used to install and fix the slide rail assembly, thereby improving the installation speed of the slide rail assembly.

[0008] Furthermore, a locking groove is provided on the top of the second slide rail, and a bolt is threaded into the inner cavity of the locking groove. The locking groove facilitates locking the second slide rail into the inner cavity of the first slide rail.

[0009] Furthermore, guide blocks are connected to both outer sides of the second slide rail. The guide blocks are slidably disposed in the inner cavity of the first slide rail. The guide blocks can reduce the coefficient of friction between the second slide rail and the first slide rail, thereby improving the smoothness of the movement of the second slide rail.

[0010] Furthermore, a second spring is externally connected to the second trapezoidal block, and the other end of the second spring is connected to the inner cavity of the hollow shell. The second spring can drive the second trapezoidal block to return to its original position after the movement is completed, thereby improving the overall smoothness of the movement of the device.

[0011] The beneficial effects of this utility model are as follows: by adding a T-shaped block, a first spring, and a first trapezoidal block, the impact force generated by the collision of the second slide rail is buffered when the second slide rail slides in the inner cavity of the slide rail assembly and the first slide rail, thereby avoiding noise and reduced service life of the second slide rail due to impact force. At the same time, by adding a second trapezoidal block, a second spring, and a rubber plate, the sliding speed of the second slide rail is automatically reduced when the T-shaped block is impacted, thereby avoiding damage caused by collision between the second slide rail and external objects, and reducing noise generation.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] In this embodiment, refer to Figure 1 and Figure 2The specific implementation of the double-opening two-section slide rail includes a slide rail assembly 1, a first slide rail 2, and a second slide rail 3. The first slide rail 2 is slidably disposed in the inner cavity of the slide rail assembly 1, and the second slide rail 3 is slidably disposed in the inner cavity of the first slide rail 2. A buffer mechanism 4 is connected to the right side of the second slide rail 3. The buffer mechanism 4 includes a hollow shell 41. A first trapezoidal block 42 is slidably connected to the right side of the hollow shell 41. A second trapezoidal block 44 is slidably connected to both ends of the inner cavity of the hollow shell 41. A rubber plate 47 is connected to one end of the two second trapezoidal blocks 44 that is far apart from each other. A first spring 45 is connected between the first trapezoidal block 42 and the hollow shell 41, and a T-shaped block 43 is connected to the other end of the first trapezoidal block 42.

[0019] The slide rail assembly 1, the first slide rail 2, and the second slide rail 3 are common slide rails in the prior art, and the instruction manual is attached. Figure 1 The length of the slide rail assembly 1 can be changed so that the length of the slide rail assembly 1 is consistent with the length of the second slide rail 3 after full movement, so that the second slide rail 3 can slide in the inner cavity of the slide rail assembly 1. The hollow shell 41 is connected to the second slide rail 3. The first trapezoidal block 42 can slide inside the hollow shell 41. The first trapezoidal block 42 can drive the second trapezoidal block 44 to move. The first spring 45 can drive the first trapezoidal block 42 to return to its original position after the first trapezoidal block 42 has finished moving. The inner cavities of the first spring 45 and the second spring 46 are equipped with damping rods to reduce the rebound force.

[0020] Please see Figure 3 and Figure 4 The inner cavity of the slide rail assembly 1 is evenly distributed with balls 11 on both sides, and the inner cavity of the slide rail assembly 1 is provided with ball grooves that are compatible with the balls 11. The balls 11 can reduce the coefficient of friction between the first slide rail 2 and the slide rail assembly 1, thereby improving the smoothness of the movement of the first slide rail 2.

[0021] The bottom left and right ends of the slide rail assembly 1 are connected to the assembly frame 12. The bottom of the assembly frame 12 is provided with an installation groove. The assembly frame 12 can install and fix the slide rail assembly 1, thereby improving the installation speed of the slide rail assembly 1. The top of the second slide rail 3 is provided with a locking groove 32. The inner cavity of the locking groove 32 is threaded with a bolt. The locking groove 32 facilitates locking the second slide rail 3 into the inner cavity of the first slide rail 2.

[0022] Guide blocks 31 are connected to both sides of the second slide rail 3. The guide blocks 31 are slidably disposed in the inner cavity of the first slide rail 2. The guide blocks 31 can reduce the friction coefficient between the second slide rail 3 and the first slide rail 2 and improve the smoothness of the movement of the second slide rail 3. The second trapezoidal block 44 is externally connected to a second spring 46. The other end of the second spring 46 is connected to the inner cavity of the hollow shell 41. The second spring 46 can drive the second trapezoidal block 44 to return to its original position after the movement is completed, thereby improving the overall smoothness of the movement of the device.

[0023] First, the position of slide rail assembly 1 is fixed, so that the first slide rail 2 slides in the inner cavity of slide rail assembly 1, and the second slide rail 3 slides in the inner cavity of the first slide rail 2. When the second slide rail 3 slides in the inner cavity of the first slide rail 2 or slide rail assembly 1, the T-shaped block 43 on the right side of the second slide rail 3 will hit the obstacle, and finally the T-shaped block 43 will retract into the inner cavity of the hollow shell 41. Then, the T-shaped block 43 will abut against the two second trapezoidal blocks 44, so that the rubber plate 47 will adhere to the inner cavity of the first slide rail 2 or slide rail assembly 1, thereby reducing the movement speed of the second slide rail 3 and reducing the impact force generated by the buffer mechanism 4 and the second slide rail 3 when sliding in the inner cavity of slide rail assembly 1 and the first slide rail 2.

[0024] By adding a T-shaped block 43, a first spring 45, and a first trapezoidal block 42, the impact force generated by the second slide rail 3 when sliding in the inner cavity of the slide rail assembly 1 and the first slide rail 2 is buffered, thereby preventing the second slide rail 3 from causing noise and reducing its service life due to impact. At the same time, by adding a second trapezoidal block 44, a second spring 46, and a rubber plate 47, when the T-shaped block 43 is impacted, the sliding speed of the second slide rail 3 is automatically reduced, thereby preventing the second slide rail 3 from colliding with external objects and causing damage and noise.

[0025] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the scope of protection of the present invention.
