Detailed implementation manners

[0034] The following combines the drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0035] For the convenience of description, unless otherwise specified, the left and right directions mentioned below are Figure 1 the same as the left and right directions of itself, and the up and down directions mentioned below are Figure 1 the same as the up and down directions of itself.

[0036] As Figures 1 to 3 shown, this embodiment provides a protective net, and the protective net includes a telescopic mechanism 2 and a positioning frame 1 having an inlet / outlet 210; the telescopic mechanism 2 is arranged in the inlet / outlet 210 and can extend or contract along the opposite ends of the inlet / outlet 210 to realize the closing or opening of the inlet / outlet 210;

[0037] The telescopic mechanism 2 includes: a plurality of first folding components 203 and a plurality of partition components 201 arranged in sequence along the telescopic direction of the telescopic mechanism 2; adjacent two partition components 201 are connected by the first folding component 203. Each partition component 201 extends from top to bottom, each partition component 201 is located in the inlet and outlet 210, each partition component 201 is arranged in sequence from left to right and each partition component 201 slides left and right.

[0038] Any two adjacent partition components 201 are respectively connected by the first folding component 203; when any two adjacent partition components 201 approach each other, the first folding component 203 folds, and when any two adjacent partition components 201 move away from each other, the first folding component 203 unfolds.

[0039] The first folding component 203 switches between the unfolded position and the folded position. When the first folding component 203 is in the unfolded position, the distance between two adjacent partition components 201 increases, and all the partition components 201 jointly cover and shield the inlet and outlet 210, realizing the elongation of the telescopic mechanism 2, which can prevent people from passing through the inlet and outlet 210 and protect the safety of people. When the first folding component 203 is in the folded position, the distance between two adjacent partition components 201 decreases, realizing the contraction of the telescopic mechanism 2, which is convenient for people to enter and exit through the inlet and outlet 210.

[0040] Specifically, in one embodiment, the positioning frame 1 includes a first guide rail 103. Each partition component 201 respectively includes a first sliding seat 2011 and a railing 2013 fixed on the first sliding seat 2011; each first sliding seat 2011 is slidably arranged on the first guide rail 103 and each first sliding seat 2011 is arranged in sequence along the first guide rail 103, and the railings 2013 are arranged in sequence along the sliding direction of the first sliding seat 2011, and the first folding component 203 is connected to the first sliding seats 2011 of two adjacent partition components 201.

The second pulley 2023 in the second fixing seat 2026 on the second guide rail 104 is in transmission connection with the second pulley 2023 in the second fixing seat 2026 on the first guide rail 103 through a transmission component, so as to realize the sliding of two driving seats 2024 driven by one motor 2021.

[0063] Specifically, in one embodiment, the driving seat 2024 on the first guide rail 103 and the driving seat 2024 on the second guide rail 104 are respectively driven by different motors 2021.

[0064] Such as Figure 1 and Figure 10 As shown, specifically, in one embodiment, the second sliding seat 2012 includes a second sliding block; the second sliding block is provided with a second rod hole. The upper end of the railing 2013 is inserted into the first rod hole 20113 of the first sliding block 20111, and the lower end of the railing 2013 is inserted into the second rod hole of the second sliding block.

[0065] Specifically, in one embodiment, there is a first predetermined gap 207 between the upper end of the railing 2013 and the bottom wall of the first rod hole 20113, and there is a second predetermined gap between the lower end of the railing 2013 and the bottom wall of the second rod hole. The railing 2013 can slide up and down a certain distance in the first rod hole 20113 and the second rod hole. Both the first predetermined gap 207 and the second predetermined gap are reserved gaps for the up and down movement of the railing 2013, so as to avoid the phenomenon that the railing 2013 jams and fixes the first sliding seat 2011 and the second sliding seat 2012 when the guide rails are not parallel, and prevent jamming when the railing 2013 moves.

[0066] Such as Figures 1 to 3As shown in the figure, specifically, in one embodiment, the protective net further includes a reset switch, a controller 4, a first sensor 5 for detecting the approach of a human body, and a second sensor 6 for sensing rainwater. The reset switch, the controller 4, the first sensor 5, and the second sensor 6 are all installed on the first limit seat 101. The reset switch is installed on the first limit seat 101 and is located on the moving path of the driving seat 2024 on the first guide rail 103. The first sensor 5, the second sensor 6, the driver 202, and the reset switch are all electrically connected to the controller 4. After the protective net is powered on, the control system first controls the motor 2021 to move the driving seat 2024 to the reset switch and trigger the reset switch, so as to confirm the initial position of the driving seat 2024. Since the moving distance of the driving seat 2024 has been set in the program, when the unfolding or folding button of the controller 4 is pressed, the motor 2021 controls the driving seat 2024 to move, and the driving seat 2024 pushes and pulls the first sliding seat 2011 to move, so as to realize the movement of all the railings 2013. When the functions of detecting human body movement and raindrops are enabled by pressing the controller 4, the corresponding first sensor 5 and second sensor 6 will detect the corresponding signals, and each railing 2013 moves according to the setting.

[0067] Working principle of the present invention: Start the driver 202, and the driver 202 pushes the rightmost first sliding seat 2011 and / or the second sliding seat 2012 to slide. The first sliding seat 2011 and the second sliding seat 2012 slide synchronously to the left or right. When the first sliding seat 2011 and the second sliding seat 2012 slide synchronously to the left, each railing 2013 slides synchronously to the left at the same time and the distance between adjacent railings 2013 gradually decreases. Finally, all the railings 2013 are closely arranged at the leftmost end of the guide rail, and personnel can pass through the gap between the first limit seat 101 and all the railings 2013. When the first sliding seat 2011 and the second sliding seat 2012 slide synchronously to the right, each railing 2013 slides synchronously to the right at the same time and the distance between adjacent railings 2013 gradually increases. Finally, all the railings 2013 are equidistantly arranged between the first limit seat 101 and the second limit seat 102 from left to right, realizing the protective function of the protective net.

[0068] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present invention.
