Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application.

[0028] Embodiment:

[0029] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Figures 1-8 The steel ball sliding rail buffer comprises an outer rail 3, a middle rail 2 and an inner rail 1 which are sequentially and slidingly connected, and further comprises:

[0030] A main body 7 is fixedly connected to the outer rail 3.

[0031] A sliding block 4 is slidingly connected to the main body 7.

[0032] A tooth hook 101 is fixedly connected to the inner rail 1.

[0033] A positioning rotary piece 6 having a first positioning pin 601 fixedly connected thereto is rotationally connected to the sliding block 4.

[0034] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Figure 7 First and second tooth grooves 1011 and 1012 are sequentially formed in the tooth hook 101, and the first and second tooth grooves 1011 and 1012 are matched with the first positioning pin 601.

[0035] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Figure 7 When the sliding rail is installed for the first time and the drawer is installed with the sliding rail for the first time, the installer may mistakenly place the positioning rotary piece 6 out of the positioning angle. In order to solve the functional failure, the first and second tooth grooves 1011 and 1012 formed in the tooth hook 101 can be used to buckle the first positioning pin 601 on the positioning rotary piece 6 after the drawer is closed. At this time, the function can be restored by pulling out the drawer, and in the subsequent use process, the second tooth groove 1012 can be used to hook the first positioning pin 601.

[0036] A limiting groove 701 is formed in the main body 7, and a second positioning pin 602 is fixedly connected to the bottom of the positioning rotary piece 6 and matched with the limiting groove 701.

[0037] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Figure 6 It should be noted that the limiting groove 701 is provided with a positioning point.

[0038] A damping rod 8 is fixedly connected to the main body 7, and a driving end of the damping rod 8 is fixedly connected to the sliding block 4.

[0039] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Figure 4When the sliding block 4 slides to close, the damping rod 8 arranged on the main body 7 can slow down the sliding speed of the sliding block 4, thereby solving the problem that the drawer is easily impacted and makes noise due to the too fast sliding of the sliding block 4.

[0040] The main body 7 is fixedly connected with a tension spring 5, and one end of the tension spring 5 away from the main body 7 is fixedly connected to the sliding block 4.

[0041] Referring to Figures 1-8 When closing, the drawer is pushed inwards, and the drawer will drive the inner rail 1 to slide to close, and the inner rail 1 slides for a distance, and then the tooth hook 101 on the inner rail 1 will hook the first positioning pin 601 on the positioning flap 6, at this time, the inwards sliding inner rail 1 will push the second positioning pin 602 on the positioning flap 6 out of the positioning point of the limiting groove 701, at this time, under the restoring force of the tension spring 5, the sliding block 4 will slide inwards to reset, and the damping rod 8 makes the tension spring 5 slowly close, and the positioning flap 6 drives the tooth hook 101 and the inner rail 1 to slowly close, when the sliding block 4 slides to the maximum range, at this time, the drawer is in a closed state.

[0042] Referring to Figures 1-8 When opening, the drawer is pulled, and the drawer will drive the inner rail 1 to slide, and the sliding inner rail 1 will drive the tooth hook 101 to slide, at this time, the sliding inner rail 1 will synchronously pull the sliding block 4 to move outwards, and the outward sliding of the sliding block 4 will synchronously pull the positioning flap 6, and the positioning flap 6 slides in the limiting groove 701 for a distance, and then the second positioning pin 602 at the bottom of the positioning flap 6 will abut against the positioning point of the limiting groove 701, at this time, the tooth hook 101 is disengaged from the positioning flap 6, and the positions of the sliding block 4, the tension spring 5 and the damping rod 8 are also positioned with the positioning flap 6, at this time, the drawer is in an open state.

[0043] The tension spring 5, the positioning flap 6 and the sliding block 4 arranged in the device are used in cooperation, when closing the drawer, the drawer can be automatically reset under the action force of the tension spring 5, and the damping rod 8 arranged in the device can slow down the resetting speed of the sliding block 4 when closing the drawer, thereby achieving the effect of silent closing, and the tooth hook 101 with the double-tooth groove is arranged, which is convenient for hooking the positioning flap 6 during initial installation, and effectively solves the problem that the positioning flap 6 may be deviated from the positioning angle during initial installation, thereby causing the drawer to be unable to be automatically reset.

[0044] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
