Description

Technical Field

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

[0002] At present, when the drawers of general furniture or office equipment are pulled out or pushed in, a slide rail structure is used on the friction surface between the drawer and the furniture or office equipment.

[0003] In the prior art, two sets of steel ball slide rails are generally arranged on the drawer side panels to realize the opening and closing of the drawer. However, during the drawer closing process, the slide rails in the prior art still have certain shortcomings. During the drawer closing process, the slide rails in the prior art generally need to be manually pushed inward to fully reset the drawer and close it. In addition, some users may close the drawer quickly when closing the drawer, which may cause the drawer to hit the cabinet body and produce certain noise. Utility Model Content

[0004] The utility model aims to solve the problems raised in the above-mentioned background technology and proposes a steel ball rail buffer.

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

[0006] Ball rail buffers, including:

[0007] Track 1;

[0008] a second track, slidably connected to the first track;

[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 rotary vane, rotatably connected to the slider;

[0013] A tooth hook, fixedly connected to the third rail;

[0014] The tooth hook hooks the rotary piece, and when the third track slides, it pushes the slider to slide, and when the slider slides, the rotary piece slides in the slide groove on the main body to be positioned and locked.

[0015] Preferably, buckle grooves are symmetrically provided on the first track, and an elastic buckle is fixedly connected to the main body, and the elastic buckle is engaged in the buckle groove.

[0016] Furthermore, an elastic part is fixedly connected to the sliding block.

[0017] Preferably, a lock buckle is fixedly connected to the third rail, and the lock buckle is fixedly connected to the tooth hook.

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

[0019] Furthermore, a damping rod is fixedly connected to the main body, and a driving end of the damping rod is fixedly connected to the sliding block.

[0020] Compared with the prior art, the utility model provides a steel ball rail buffer, which has the following beneficial effects:

[0021] The parts not involved in the device are the same as the prior art or can be implemented by the prior art. When closing the drawer, the utility model can use the spring in the device to pull the slider, so that the drawer can automatically reset and close. At the same time, the damping rod in the device can absorb the impact force during closing and slowly close the slider, thereby effectively preventing the slider from sliding too fast and causing the drawer to collide and be damaged, and reducing the noise generated by the rapid impact of the drawer.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Embodiment 1:

[0030] Reference Figure 1-Figure 5 , ball rail buffer, comprising:

[0031] First track 1;

[0032] A second track 2, slidably connected to the first track 1;

[0033] A third rail 3, slidably connected to the second rail 2;

[0034] A main body 4 is fixedly connected to the first track 1;

[0035] A slider 5 is slidably connected to the main body 4;

[0036] A rotary vane 7 is rotatably connected to the slider 5;

[0037] A tooth hook 6 is fixedly connected to the third rail 3;

[0038] The tooth hook 6 hooks the rotary piece 7 , and when the third track 3 slides, it pushes the slider 5 to slide. When the slider 5 slides, the rotary piece 7 slides in the slide groove on the main body 4 to be positioned and locked.

[0039] It should be noted that the drawer side panel and the third track 3 are fixedly connected.

[0040] Buckle grooves 101 are symmetrically formed on the first track 1 , and an elastic buckle 403 is fixedly connected to the main body 4 , and the elastic buckle 403 is engaged in the buckle groove 101 .

[0041] Reference Figure 5 By closing the two sets of elastic buckles 403 and the buckle grooves 101, the fixing effect of the main body 4 can be improved.

[0042] An elastic portion 501 is fixedly connected to the slider 5 .

[0043] Reference Figure 5 By setting the elastic part 501 on the slide block 5, when the drawer is closed, the second rail 2 is effectively prevented from hitting the slide block 5 to generate noise.

[0044] Furthermore, the elastic portion 501 is a wave-shaped elastic sheet.

[0045] A lock buckle 301 is fixedly connected to the third track 3 , and the lock buckle 301 is fixedly connected to the tooth hook 6 .

[0046] A spring 402 is fixedly connected to the main body 4 , and one end of the spring 402 away from the main body 4 is fixedly connected to the slider 5 .

[0047] A damping rod 401 is fixedly connected to the main body 4 , and a driving end of the damping rod 401 is fixedly connected to the slider 5 .

[0048] Reference Figure 1-Figure 4 When the drawer is in the open state and needs to be closed, the staff can manually push the drawer body, and the drawer will drive the third track 3 to slide. After the third track 3 slides for a distance, the tooth hook 6 on the third track 3 will hook the rotary piece 7. At this time, the rotary piece 7 turns out, and the third track 3 continues to slide to push the slider 5 to slide. After the slider 5 slides for a distance on the main body 4, the slider 5 will slide to the rear end of the main body 4. At this time, the rotary piece 7 will hook the positioning point of the slide groove on the main body 4. At this time, the slider 5 will be hooked and fixed. At this time, the third track 3 is synchronously fixed, and the drawer will be in a closed state.

[0049] Reference Figure 1-Figure 4 The drawer is in a closed state, and when the drawer needs to be opened, the staff can pull the drawer body outward, the drawer will pull the third track 3, the third track 3 will synchronously pull the tooth hook 6 to move, the movement of the tooth hook 6 will pull the rotary piece 7 out of the positioning point of the slide groove, at this time the spring 402 is pulled to store energy, when the third track 3 slides a certain distance, the slider 5 slides to the maximum limit, at this time the drawer is completely opened.

[0050] It should be noted that during the drawer closing process, when the rotary piece 7 is turned out, the staff does not need to push the drawer. At this time, the slider 5 will slide inward under the pulling force of the spring 402, and the pulling force of the spring 402 can fully enable the slider 5 to slide closed.

[0051] It should also be noted that when the slider 5 slides to close the drawer, the damping rod 401 on the main body 4 absorbs the impact force during closing and causes the slider 5 to close slowly, thereby effectively preventing the slider 5 from sliding too fast and causing the drawer to collide and be damaged, while reducing the noise generated by the rapid collision of the drawer.

[0052] When closing the drawer, the utility model can use the spring 402 in the device to pull the slider 5, so that the drawer can automatically return to its original position and close. At the same time, the damping rod 402 in the device can absorb the impact force during closing and slowly close the slider 5, so as to effectively prevent the slider 5 from sliding too fast and causing the drawer to collide and be damaged, and at the same time reduce the noise generated by the rapid collision of the drawer.

[0053] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
