Description

Technical Field

[0001] This utility model relates to the field of slide rail rebounders, and in particular to an adjustable two-stage steel ball slide rail rebounder. Background Technology

[0002] Drawer slides are hardware connection parts fixed to the cabinet body of furniture, allowing drawers or cabinet panels to move in and out. Drawer slides are suitable for connecting drawers in wooden and steel furniture such as cabinets, furniture, filing cabinets, bathroom cabinets, etc.

[0003] Existing drawers require handles to be installed on the outer wall for manual opening, which is inconvenient. Some drawers with slide rail rebound mechanisms require force to close when closed due to items inside, which can cause internal components to collide during inertial sliding, damaging the slide rails and drawers and affecting their lifespan. Furthermore, the installation dimensions of the slide rails on the left and right sides may not be consistent during the installation of existing technologies, which may prevent the drawer from popping out effectively. Utility Model Content

[0019] Furthermore, a tension spring is fixedly connected to the slider, and the end of the tension spring away from the slider is fixedly connected to the push block.

[0020] Compared with the prior art, this utility model provides an adjustable two-stage steel ball slide rail rebounder, which has the following beneficial effects:

[0021] The parts of this device not described herein are the same as or can be implemented using existing technology. The compression spring and tension spring set in this device enable the spring force value to change at a low rate. Pressing the opening rebound device requires very little force to make the drawer fully open, achieving a gentle pressing effect. At the same time, the adjusting cam set on the inner rail can be adjusted when installing the slide rail, and the front and back distance of the left and right slide rails can be adjusted to achieve the ideal size.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Example:

[0032] Reference Figures 1-7 Adjustable dual-stage ball bearing slide rail bouncer, including:

[0033] Outer rail 1;

[0034] The middle rail 3 is slidably connected to the outer rail 1;

[0035] Inner rail 2 is slidably connected to middle rail 3;

[0036] The main body 4 is fixedly connected to the outer rail 1;

[0037] Push block 5 is slidably connected to the main body 4;

[0038] Slider 6 is slidably connected to the main body 4;

[0039] Push block 5 and slider 6 abut against each other;

[0040] Toothed hook 7 is fixedly connected to inner rail 2;

[0041] The first rotary blade 8 is rotatably connected to the push block 5, and the first rotary blade 8 is matched with the toothed hook 7.

[0042] An adjusting cam 10 is rotatably connected to the outer rail 1, and the adjusting cam 10 abuts against the toothed hook 7.

[0043] Reference Figure 3 , Figure 5 , Figure 6 If the front-to-back distance between the left and right slide rails is not properly installed during drawer installation, and the two slide rails are not of the same size, the drawer will not spring back when pressed. At this time, the staff can use a screwdriver to rotate the adjusting cam 10 set on the outer rail 1. The adjusting cam 10 will press the front-to-back position of the slide rail, and the front-to-back distance between the left and right slide rails can be adjusted to the ideal size.

[0044] The push block 5 is rotatably connected to the second rotary blade 9, and the main body 4 is provided with a sliding groove 401, which matches the second rotary blade 9 with the sliding groove 401.

[0045] A compression spring 11 is fixedly connected to the main body 4, and the end of the compression spring 11 away from the main body 4 is fixedly connected to the slider 6.

[0046] A tension spring 12 is fixedly connected to the slider 6, and the end of the tension spring 12 away from the slider 6 is fixedly connected to the push block 5.

[0047] Reference Figures 1-7 When the drawer is closed, the drawer moves the inner rail 2 to close. The toothed hook 7 on the inner rail 2 slides synchronously with the inner rail 2. After the toothed hook 7 slides a certain distance, it will hook the first rotating plate 8. At this time, the movement of the inner rail 2 will push the push block 5 to slide. At this time, the tension spring 12 and the push block 5 slide inward together by 27mm. During the sliding process of the push block 5, the slider 6 and the pressure spring 11 also move inward together. When the slider 6 slides to the bottom, the inner rail 2 rebounds by 4mm under the action of the pressure spring 11. At the same time, the iron nail on the second rotating plate 9 slides to the positioning angle. The slider 6 and the tension spring 12 follow and do not move. At this time, the drawer is in the closed state.

[0048] Reference Figures 1-7 When opening the drawer, press the drawer inward, and the drawer will be pushed inward 4mm to the bottom. The toothed hook 7 will drive the first rotating plate 8 to slide. At the same time, the slider 6 and the pressure spring 11 will also slide inward with the first rotating plate 8 to the bottom. At the same time, the iron nail on the second rotating plate 9 will disengage from the positioning angle of the slide groove 401. At this time, the pressure spring 11 will return to its original position under its own elastic force. The slider 6 will slide outward under the action of the pressure spring 11. At the same time, the first rotating plate 8 will drive the toothed hook 7 to slide out. The sliding out of the toothed hook 7 will simultaneously drive the inner rail 2 to slide out. At this time, the push block 5 will receive the elastic force of the tension spring 12 and push the toothed hook 7 on the inner rail 2. The drawer will slide outward and open under the rebound force of the first pressure spring 11 and the second tension spring 12. At this time, the drawer is in the open state.

[0049] The compression spring 11 and tension spring 12 of this device enable a low rate of change in spring force, allowing the drawer to open completely with minimal force when the spring is pressed, resulting in a gentle pressing effect. At the same time, the adjusting cam 10 on the inner rail 2 allows for adjustment during the installation of the slide rails, enabling the adjustment of the front-to-back distance between the left and right slide rails to achieve the desired dimensions.

[0050] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
