Description

Slide rail with double bouncer Technical Field

[0001] This utility model relates to the field of slide rails, specifically to a slide rail with double rebounders. Background Technology

[0002] A slide rail with double rebound mechanism is a type of furniture hardware that combines the functions of a slide rail and a double rebound mechanism. It is mainly used in furniture components such as drawers to achieve smooth sliding and automatic closing.

[0003] Typically composed of components such as rails, sliders, ball bearings, or rollers, it provides stable sliding support, ensuring that the drawer can open and close smoothly; a double rebound mechanism has two springs. When the drawer is closed, both springs are compressed simultaneously to store energy. At the end of the closing process, the springs release energy in stages, providing a gentle damping effect to ensure that the drawer closes slowly. If one spring fails, the other can still provide basic rebound force, improving reliability.

[0004] The common way to connect the rebound mechanism to the drawer slide is by using screws. After long-term use, the spring elasticity decreases, affecting the rebound of the drawer. As a result, it is necessary to disassemble the rebound mechanism and replace the spring or the rebound mechanism. Due to the small space inside the table, it is necessary for people to climb in and use a screwdriver to unscrew the screws in order to disassemble the rebound mechanism. Installing the rebound mechanism is also troublesome. Therefore, a drawer slide with a double rebound mechanism was proposed. Summary of the Invention

[0005] The purpose of this utility model is to solve the above defects and provide a slide rail with double rebounders. When installing the rebounders, the limiting groove and the L-shaped limiting frame are combined with the adjusting screw to control the limiting block to abut against the baffle, which makes the double rebounders easy and quick to install and remove. This solves the technical problem that the rebounders are inconvenient to install and remove due to space constraints in the prior art.

[0006] The objective of this utility model is achieved through the following means:

[0007] A slide rail with double rebounders includes an outer rail shell, a middle rail shell, an inner rail shell, and double rebounders. The middle rail shell is slidably installed on the inner left side of the outer rail shell, and the inner rail shell is slidably installed on the inner left side of the middle rail shell. The double rebounders are installed on the inner right side of the outer rail shell. Each double rebounder includes a base plate. A vertical plate is welded and fixed to the right end of the base plate. An adjusting screw is threadedly installed on the inner right end of the vertical plate. An adjusting disc is provided on the outer side of the right end of the adjusting screw. A limit block is rotatably installed on the right end of the adjusting screw. Limit grooves are provided on both the upper and lower sides of the left end of the base plate. An L-shaped limit frame is provided on the inner left side of the limit groove inside the outer rail shell. A baffle is provided on the inner right end of the outer rail shell. Fixed seats are provided on both the upper and lower sides of the front end of the base plate.

[0008] Furthermore, the adjusting disc is welded and fixed to the adjusting screw, and the L-shaped limiting frame is welded and fixed to the outer rail shell. The adjusting disc 12 is used to control the rotation of the adjusting screw 11.

[0009] Furthermore, the baffle is welded and fixed to the outer rail shell, and the fixing seat is welded and fixed to the base plate.

[0010] Furthermore, a telescopic rod is installed on the inner left end of the fixed base, and the telescopic rod is fixedly connected to the fixed base. The telescopic rod 9 makes the compression and release stroke of the spring 8 more stable.

[0011] Furthermore, a spring is installed inside the fixed base outside the telescopic rod, and a rebound block is fixed to the left end of the telescopic rod. The spring 8 enables the rebound block 16 to have a rebound force.

[0012] Furthermore, side stops are provided on both the upper and lower sides of the front end of the limiting groove, and the side stops are welded and fixed to the bottom plate. The side stops 6 limit the upper and lower sides of the L-shaped limiting frame 3 after it is combined with the limiting groove 5.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a limiting groove on one side of the base plate, which, in conjunction with an L-shaped limiting frame on one side of the outer track, allows for quick fixing or disassembly of the base plate. The position of the limiting block is changed by rotating the adjusting screw, so that the limiting block abuts against or moves away from the baffle. This makes it convenient and quick to assemble and disassemble the double rebounder inside the slide rail without tools, and facilitates blind operation, thus solving the problems mentioned in the background art.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Referring to Figures 1, 2, and 3, the slide rail with double rebounders in this embodiment includes an outer rail shell 1, a middle rail shell 14, an inner rail shell 15, and double rebounders. The middle rail shell 14 is slidably installed on the inner left side of the outer rail shell 1, and the inner rail shell 15 is slidably installed on the inner left side of the middle rail shell 14. The double rebounders are installed on the inner right side of the outer rail shell 1. The double rebounders include a base plate 4. A vertical plate 10 is welded and fixed to the right end of the base plate 4. An adjusting screw 11 is installed on the inner right end of the vertical plate 10 through a threaded connection. An adjusting disc 12 is provided on the outer side of the right end of the adjusting screw 11. A limit block 13 is rotatably installed on the right end of the adjusting screw 11. Limit grooves 5 are opened on the upper and lower sides of the left end of the base plate 4. An L-shaped limit frame 3 is provided on the inner left side of the limit groove 5 inside the outer rail shell 1. A baffle 2 is provided on the inner right end of the outer rail shell 1. Fixed seats 7 are provided on the upper and lower sides of the front end of the base plate 4.

[0021] The double bouncer has a buffer structure and other structures inside, but since it does not involve structural improvements, it will not be described in detail.

[0022] As shown in Figures 2 and 3, the adjusting disc 12 is welded and fixed to the adjusting screw 11, and the L-shaped limit frame 3 is welded and fixed to the outer rail shell 1. The adjusting disc 12 is used to control the rotation of the adjusting screw 11.

[0023] As shown in Figures 1, 2 and 3, the baffle 2 is welded and fixed to the outer rail shell 1, and the fixing seat 7 is welded and fixed to the base plate 4.

[0024] As shown in Figures 1, 2 and 3, a telescopic rod 9 is installed on the left end of the interior of the fixed base 7, and the telescopic rod 9 is fixedly connected to the fixed base 7. The telescopic rod 9 makes the compression and release stroke of the spring 8 more stable.

[0025] As shown in Figures 2 and 3, a spring 8 is installed inside the fixed base 7 outside the telescopic rod 9, and a rebound block 16 is fixed to the left end of the telescopic rod 9. The spring 8 enables the rebound block 16 to have a rebound force.

[0026] As shown in Figures 2 and 3, side stops 6 are provided on both the upper and lower sides of the front end of the limiting groove 5, and the side stops 6 are welded and fixed to the base plate 4. The side stops 6 limit the upper and lower sides of the L-shaped limiting frame 3 after it is combined with the limiting groove 5.

[0027] The disassembly and assembly process of the slide rail with double rebounders in this embodiment is as follows: When disassembling the double rebounders, rotating the adjusting disc 12 causes the adjusting screw 11 to rotate. Under the threaded engagement of the adjusting screw 11 and the vertical plate 10, the rotational motion of the adjusting screw 11 is converted into linear motion, thereby causing the limiting block 13 to move away from the baffle 2 to cancel the limiting. Then, the bottom plate 4 is pulled towards one side of the baffle 2, causing the limiting groove 5 to separate from the L-shaped limiting frame 3. The rebounders are then removed, and the spring 8 is replaced. Alternatively, after replacing the rebounders, the rebounders can be removed. The base plate 4 is attached to the inside of the right end of the outer rail shell 1. The limiting groove 5 is aligned with the L-shaped limiting frame 3. The base plate 4 is moved toward the L-shaped limiting frame 3 so that the L-shaped limiting frame 3 is engaged with the limiting groove 5. Then, the adjusting plate 12 is rotated. The adjusting screw 11 and the vertical plate 10 are engaged by the thread, which converts the rotational motion of the adjusting screw 11 into the linear motion of the adjusting screw 11 until the limiting block 13 and the baffle 2 abut against each other. This one-step process makes the installation of the rebounder convenient and quick. It can be disassembled and assembled without tools and supports one-handed operation and blind operation.

[0028] 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.
