[0026] When the slider 2 is in use, the slider body 2 slides along the track of the slide rail main body 1. At this time, the ball 3 rolls and pushes the ball contact locking control structure 7 between the two adjacent balls 3 outward, so that the ball contact locking control structure 7 drives the metal connecting piece 8 and the adjustable opening and closing component 6 to be pushed outward synchronously. The metal connecting piece 8 will contact the electromagnet 9 and fix the metal connecting piece 8 through magnetic attraction to prevent the ball contact locking control structure 7, the metal connecting piece 8 and the adjustable opening and closing component 6 from resetting. The stability is strong, thereby opening the opening of the auxiliary heat dissipation channel 5, facilitating the rapid heat dissipation during the sliding of the guide rail, avoiding heat accumulation at the sliding point, and improving the service life of components. When the slider body 2 is notified to slide, the electromagnet 9 is powered off and pushed inward to drive the ball contact locking control structure 7, the metal connecting piece 8 and the adjustable opening and closing component 6 to reset. The ball contact locking control structure 7 can abut against the ball 3 to achieve a locked state, preventing the slider body 2 and the slide rail main body 1 from sliding freely and avoiding excessive wear.

[0027] Combine Figure 1 、 Figure 3As shown, the ball contact locking control structure 7 includes a plurality of locking sliders 10 arranged in the slider body 2. The locking sliders 10 are made of rubber material and the heads of the locking sliders 10 are in the shape of an arc cone. The locking sliders 10 are located in the gap between two adjacent balls 3. The locking sliders 10 are connected to the metal connector 8 through a connecting plate 11.

[0028] Specifically, when in a stationary state, the locking slider 10 abuts against the ball 3 to achieve a locked state, preventing the slider body 2 and the slide rail body 1 from sliding freely and avoiding excessive wear. During use, the slider body 2 slides along the track of the slide rail body 1. At this time, the ball 3 rolls and pushes the locking slider 10 located between two adjacent balls 3 outward, so that the locking slider 10 drives the metal connector 8 and the adjustable opening and closing component 6 to be pushed outward synchronously. The metal connector 8 will contact the electromagnet 9 and fix the metal connector 8 through magnetic attraction to avoid the locking slider 10, the metal connector 8 and the adjustable opening and closing component 6 from resetting. The stability is strong, thereby opening the opening of the auxiliary heat dissipation channel 5, facilitating the rapid dissipation of heat during the sliding of the guide rail, avoiding heat accumulation at the sliding point, and improving the service life of components.

[0029] Combine Figure 2 、 Figure 3 As shown, the metal connector 8 includes a metal plate 12 arranged at the tail of the connecting plate 11. One end of the connecting plate 11 is connected to a plurality of locking sliders 10, and the other end is connected to the metal plate 12.

[0031] The adjustable opening and closing component 6 includes a heat dissipation opening and closing slide plate 13 disposed in the slider body 2 . The heat dissipation opening and closing slide plate 13 extends into the auxiliary heat dissipation channel 5 and is adapted to the shape of the auxiliary heat dissipation channel 5 .

[0032] In this embodiment, in the sliding state, the heat dissipation opening and closing slide 13 withdraws from the auxiliary heat dissipation channel 5, opening the opening of the auxiliary heat dissipation channel 5, facilitating the rapid heat dissipation of the heat during the sliding process of the guide rail, avoiding heat accumulation at the sliding point, and improving the service life of components.

[0033] Combine Figure 2 As shown, the heat dissipation opening and closing slide plate 13 is fixed to the metal plate 12 , and a first spring 14 is provided at the tail of the heat dissipation opening and closing slide plate 13 .

[0034] In this embodiment, the heat dissipation opening and closing slide plate 13 can be elastically reset by the elastic force of the first spring 14 after the electromagnet 9 pushes the metal plate 12 back to its original position.

[0035] The electromagnet 9 is provided with a plurality of limit sliders 15 , and a second spring 16 is provided at the tail of the limit slider 15 . One end of the second spring 16 is fixedly connected to the limit slider 15 , and the other end is fixedly connected to the inner wall of the slider body 2 .

[0036] In this embodiment, during the sliding process of the electromagnet 9, the limiting slider 15 plays a limiting role, and the second spring 16 can achieve elastic reset.

[0037] The electromagnet 9 is provided with a slide rod 17 extending out of the slider body 2 , and the slide rod 17 is in sliding engagement with the slider body 2 .

[0038] In this embodiment, the slide bar 17 can control the electromagnet 9 to slide.

[0039] Combine Figure 2 As shown, the electromagnet 9 is provided with a power switch 18, and the slide bar 17 is provided with a switch button rod 19 that can move toward or away from one end of the power switch 18.

[0040] In this embodiment, when the electromagnet 9 needs to be powered on or off, the switch button rod 19 is moved toward one end close to the power switch 18, and the power switch 18 is pressed to achieve power on or off.

[0041] Combine Figure 1 、 Figure 2 As shown, a plurality of third springs 20 are provided on the switch button rod 19 .

[0042] In this embodiment, the third spring 20 can automatically reset the switch button rod 19 after the switch button rod 19 is pressed.

[0043] Combine Figure 2 As shown, the width of the auxiliary heat dissipation channel 5 gradually increases from the side close to the ball channel 4 to the side away from the ball channel 4.

[0044] In this embodiment, the width of the auxiliary heat dissipation channel 5 gradually increases from the side close to the ball channel 4 to the side away from the ball channel 4, so as to avoid affecting the rolling of the balls 3.

[0045] The working principle of this utility model is:

[0046] When the cam 12 is in a stationary state, the locking slider 10 abuts against the ball bearings 3 to achieve a locked state, preventing the slider body 2 and the slide rail body 1 from sliding freely and avoiding excessive wear. During use, the slider body 2 slides along the track of the slide rail body 1, and at this time, the ball bearings 3 roll and push the locking slider 10 located between the two adjacent ball bearings 3 outward, so that the locking slider 10 and the connecting plate 11 drive the metal plate 12 and the heat dissipation opening and closing slide plate 13 to be pushed outward synchronously, and the metal plate 12 will contact the electromagnet 9 and fix the metal plate 12 through magnetic attraction to prevent the locking slider 10, the connecting plate 11, the metal plate 12 and the heat dissipation opening and closing slide plate 13 from resetting. The stability is strong, thereby opening the opening of the auxiliary heat dissipation channel 5, facilitating the rapid heat dissipation of the heat during the sliding process of the guide rail, avoiding heat accumulation at the sliding part, and improving the service life of the components. The metal plate 12 can contact the electromagnet 9 and be attracted by magnetism.

[0047] The heat dissipation opening and closing slide 13 can realize elastic reset by the elastic force of the first spring 14 after the electromagnet 9 pushes the metal plate 12 back to its original position. During the sliding process of the electromagnet 9, the limit slider 15 plays a role of limiting, and the second spring 16 can realize elastic reset.

[0048] The slide bar 17 can control the sliding of the electromagnet 9. When the electromagnet 9 needs to be powered on or off, the switch button rod 19 is moved toward the end close to the power switch 18, and the power switch 18 is pressed to turn the power on and off. The third spring 20 can automatically reset the switch button rod 19 after pressing the switch button rod 19, and the width of the auxiliary heat dissipation channel 5 gradually increases from the side close to the ball channel 4 to the side away from the ball channel 4, so as to avoid affecting the rolling of the ball 3.
