[0023] Example

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, an embodiment of this utility model proposes an industrial sliding door guide rail, including a guide rail body 1 and a track groove 2 formed along the length of the guide rail body 1. A sliding block 5 is slidably connected to the track groove 2 of the guide rail body 1. The sliding block 5 includes: a slider body 501 adapted to the track groove 2; two positioning rods 508, both of which are slidably connected to the corresponding telescopic holes 5013 formed in the slider body 501, and a limiting hole 5014 coaxially formed on one side of the telescopic hole 5013 of the slider body 501; and a limiting rod 5010 fixed to the end of the positioning rod 508, the limiting rod 5010 being slidably connected to the limiting hole 5014 of the slider body 501, and a spring 509 sleeved on the positioning rod 508, the two ends of the spring 509 abutting against the slider body 501 and the limiting rod 5010 respectively.

[0025] It should be noted that a track groove 2 is provided on the guide rail body 1 to realize the sliding limit of the sliding block 5. In actual use, the sliding door is connected and fixed to the sliding block 5, driving the sliding door to rise and fall. The main body of the sliding block 5 is the slider body 501. By sliding the positioning rod 508 at the telescopic hole 5013 of the slider body 501, the emergency braking of the sliding block 5 can be realized to avoid safety accidents. By setting the limiting hole 5014 on the slider body 501, the sliding limit of the limiting rod 5010 is realized. The limiting rod 5010 is connected and fixed to the positioning rod 508, so that the positioning rod 508 and the limiting rod 5010 extend and retract synchronously. By sleeved on the positioning rod 508, the two ends of the spring 509 abut against the slider body 501 and the limiting rod 5010 respectively, the positioning rod 508 and the limiting rod 5010 can be automatically reset. This method can realize the emergency braking of the sliding block 5 and the sliding door, ensuring the safety of the device.

[0026] like Figure 1 and Figure 2 As shown, in some embodiments, the guide rail body 1 has equidistantly distributed positioning holes 3, which are adapted to the positioning rod 508.

[0027] It should be noted that by opening equidistantly distributed positioning holes 3 on the guide rail body 1, when the positioning rod 508 slides outward, it will slide and close to the corresponding positioning hole 3, thereby realizing the braking effect of the sliding block 5 and the sliding door.

[0028] like Figure 2 and Figure 3 As shown, in some embodiments, an electric push rod 505 is installed on the slider body 501, and a wedge block 506 is fixedly connected to one side of the electric push rod 505. The wedge block 506 is slidably connected to the limiting cavity groove 5012 correspondingly opened in the slider body 501, and a wedge surface 507 is opened on the side wall of the wedge block 506. A inclined groove 5011 is provided on one side of the limiting rod 5010, and the wedge surface 507 is adapted to the inclined groove 5011.

[0029] It should be noted that by installing an electric push rod 505 on the slider body 501, the electric push rod 505 can drive the wedge block 506 to extend and retract. A wedge surface 507 is provided on the side wall of the wedge block 506, and a groove 5011 is provided on one side of the limiting rod 5010. The wedge surface 507 and the groove 5011 are adapted to each other. When the wedge block 506 moves, it can guide the limiting rod 5010 to move outward. The spring 509 is compressed, causing the positioning rod 508 to move outward. The positioning rod 508 moves and closes to the corresponding positioning hole 3, realizing the emergency braking of the sliding block 5 and the sliding door.

[0030] like Figure 2 and Figure 3 As shown, in some embodiments, a protective cover 504 is fixedly connected to one side of the slider body 501, and the protective cover 504 covers the outside of the electric push rod 505.

[0031] It should be noted that the protective cover 504 is designed to provide safety protection for the electric push rod 505 and prevent accidental contact.

[0032] like Figure 1 and Figure 2 As shown, in some embodiments, a support platform 503 is integrally formed on one side of the slider body 501, and an arc-shaped groove 502 is formed between the slider body 501 and the support platform 503. An arc-shaped protrusion 4 is formed on the guide rail body 1, and the arc-shaped groove 502 is adapted to the arc-shaped protrusion 4.

[0033] It should be noted that by setting an arc-shaped groove 502 between the slider body 501 and the support platform 503, the arc-shaped groove 502 is adapted to the arc-shaped protrusion 4, so that the slider 5 can slide stably in the track groove 2 of the guide rail body 1, and the support platform 503 is used for fixing external components.

[0034] It should also be noted that in actual use, a controller can be installed on the frame outside the guide rail body 1, and an infrared sensor and a photoelectric sensor can be installed at the bottom of the outer frame of the guide rail body 1. The controller model is S7-400, the infrared sensor model is D6T-8L-09, and the photoelectric sensor model is MV100-RT. The photoelectric sensor can detect whether there is an object in front based on the change of light signal, and the infrared sensor can detect human body signals. Both the photoelectric sensor and the infrared sensor are electrically connected to the controller, and the controller is electrically connected to the electric push rod 505. When there is an object or person under the sliding door, the controller can control the electric push rod 505 to work and realize the emergency braking of the device.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
