Description

Technical Field

[0001] The utility model relates to the technical field of slide rail devices, in particular to a ball slide rail rebounder. Background Art

[0002] A slide rail is a hardware connecting component fixed on the cabinet body of furniture for the drawer or cabinet board of the furniture to move in and out. The slide rail is applicable to the drawer connection of furniture such as cabinets, furniture, document cabinets, bathroom cabinets, etc., made of wood and steel. Among them, the ball slide rail is a relatively commonly used installation track.

[0003] However, generally only two springs are installed in the existing ball slide rails. When the drawer needs to be fully popped open, the springs need to be adjusted to a very large elastic force value, and the feeling of pressing the drawer is not gentle enough. At the same time, when the existing ball slide rails are closed, the middle rail is prone to produce a certain impact noise with the slider, and the mute effect during closing needs to be further improved. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the problems put forward in the above background art, and a ball slide rail rebounder is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] The ball slide rail rebounder includes:

[0007] A first rail;

[0008] A second rail, slidably connected to the first rail;

[0009] A third rail, slidably connected to the second rail;

[0010] A main body, fixedly connected to the first rail;

[0011] A slider, slidably connected to the main body;

[0012] A tooth hook, fixedly connected to the third rail;

[0013] A rotating piece, rotatably connected to the slider;

[0014] A limiting piece, rotatably connected to the slider;

[0015] A limiting groove is opened on the main body, and the limiting piece and the limiting groove are matched.

[0016] Preferably, a ball holder is connected to the second rail, a ball bar is connected inside the first rail, and steel balls are connected to both the ball holder and the ball bar.

[0017] Furthermore, a compression spring is fixedly connected to the slider, and the end of the compression spring away from the slider is fixedly connected to the main body.

[0018] Preferably, a push block is slidably connected to the main body, a tension spring is fixedly connected to the push block, and one end of the tension spring away from the push block is fixedly connected to the slider.

[0019] Furthermore, a buffer head is fixedly connected to the slider.

[0020] Preferably, a positioning seat is fixedly connected to the third track.

[0021] With the present utility model, when opening the drawer through this device, the compression spring 6 can initially eject the third track, and during the ejection process, the tension spring and the push block can bounce back a second time to push the third track, and then bounce back a second time to push the drawer.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0030] Example 1:

[0031] Referring to Figures 1 - 6 , a steel ball slide rail rebounder, comprising:

[0032] A first rail 1;

[0033] A second rail 2, slidably connected to the first rail 1;

[0034] A third rail 3, slidably connected to the second rail 2;

[0035] A main body 5, fixedly connected to the first rail 1;

[0036] A slider 7, slidably connected to the main body 5;

[0037] A tooth hook 4, fixedly connected to the third rail 3;

[0038] A rotating vane 11, rotatably connected to the slider 7;

[0039] A limiting piece 10, rotatably connected to the slider 7;

[0040] A limiting groove 501 is formed in the main body 5, and the limiting piece 10 and the limiting groove 501 are matched.

[0041] A ball bearing holder 14 is connected to the second rail 2, a ball bearing strip 13 is connected inside the first rail 1, and steel balls 12 are connected to both the ball bearing holder 14 and the ball bearing strip 13.

[0042] It should be noted that the steel ball 12 on the ball bearing strip 13 abuts against the outer wall of the second rail 2;

[0043] The steel ball 12 on the ball bearing holder 14 abuts against the outer wall of the third rail 3.

[0044] A compression spring 6 is fixedly connected to the slider 7, and one end of the compression spring 6 away from the slider 7 is fixedly connected to the main body 5.

[0045] A push block 8 is slidably connected to the main body 5, a tension spring 9 is fixedly connected to the push block 8, and one end of the tension spring 9 away from the push block 8 is fixedly connected to the slider 7.

[0046] A buffer head 701 is fixedly connected to the slider 7.

[0047] Referring to Figure 4 , by means of the buffer head 701 provided on the slider 7, the impact sound between the second rail 2 and the slider 7 can be reduced, and the sound when the drawer is closed can be further reduced.

[0048] A positioning seat 15 is fixedly connected to the third rail 3.

[0049] When in the closed state, pushing the third track 3 will drive the tooth hook 4 to move. After the third track 3 moves a certain distance, the third track 3 abuts against the push block 8, and the rotating vane 11 will rotate and engage into the rotating groove of the tooth hook 4. At this time, the tooth hook 4 will hook the rotating vane 11. Then the third track 3 will drive the push block 8 to slide inward. The sliding of the push block 8 will pull the tension spring 9 and the slider 7 to move. When the push block 8 slides to the bottom, stop pushing the third track 3 inward. At this time, under the elastic force of the compression spring 6, the iron nail on the limit piece 10 hooks the positioning angle on the limit groove 501. At this time, the slider 7 and the tension spring 9 stop moving, and the whole slide rail is in the closed state.

[0050] When in the open state, the operator pushes the third track 3 inward. At this time, the tooth hook 4 drives the rotating vane 11 to move inward. At the same time, the slider 7 and the compression spring 6 also move inward together with the rotating vane 11 to the bottom. Then the iron nail on the limit piece 10 disengages from the positioning angle of the limit groove 501. At this time, the compression spring 6 rebounds and resets. Under the reset force of the compression spring 6, the slider 7 slides outward. At the same time, the rotating vane 11 drives the tooth hook 4 to slide outward, and the tooth hook 4 will drive the third track 3 to slide out. At this time, the push block 8 is under the action of the tension spring 9 and will push the cross section of the third track 3. At this time, it will bounce back in two stages and push out. After the third track 3 is pushed out in the first stage by the compression spring 6 and bounced back in the second stage by the tension spring 9 and the push block 8, it will open under the inertia of sliding outward. At this time, the slide rail is in the open state.

[0051] By using this device to open the drawer, the compression spring 6 can initially eject the third track 3. During the ejection process, the tension spring 9 and the push block 8 can bounce back in the second stage to push the third track 3, and then bounce back in the second stage to push the drawer. Under the action of the two-stage pushing force to open the drawer, the elastic force value of the spring does not need to be set very large to completely open the drawer body, which improves the use effect of opening the drawer.

[0052] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, makes equivalent replacement or change, and should be covered by the protection scope of the present utility model.
