As shown in fig. 1-3, an induction type automatic lifting guard rail comprises a base 1, wherein the base 1 is fixed on a balcony floor 2 and is in a U shape matched with a balcony, two ends of the base 1 are connected with wall boards, a plurality of vertical rods 3 are fixedly connected above the base 1, the vertical rods 3 are at the same interval, and the vertical rods 3 enclose a three-side guard rail structure. The vertical rod 3 is arranged to be a hollow structure, the top rods 4 are arranged in the vertical rods 3 in a staggered manner, namely the top rod 4 is arranged in one vertical rod 3 of two adjacent vertical rods 3, the intervals between the top rods 4 on the same plane are the same, the top ends of the top rods 4 are connected with a transverse plate 5, the transverse plate 5 is positioned above the base 1 and has the same structure with the base 1, the two ends of the transverse plate 5 are in sliding contact with the wall board, the inner parts of the top rods 4 are in threaded connection with screw rods 11, the screw rods 11 are respectively arranged in the vertical rods 3 where the top rods 4 are positioned, the screw rods 11 rotate in the vertical rods 3, the bottom ends of the screw rods 11 penetrate through the vertical rods 3 and extend into the base 1 and are connected with bevel gears A10, a servo motor 6 is arranged in the base 1, the output end of the servo motor 6 is rotatably connected with a horizontal rotating rod 9, a, below each bevel gear a10, a bevel gear B12 meshes. Set up three servo motor 6 in base 1, be connected with the transmission of 3 montants in the trilateral guardrail of balcony respectively, three servo motor 6 is connected on same circuit, but simultaneous working to electric connection is on the control mainboard, through the steerable servo motor 6 of control mainboard.

Under the balcony railing normal use condition, in ejector pin 4 inserted montant 3 completely, diaphragm 5 bottom surface and 3 top surfaces sliding contact of montant can lean on the guardrail. Be connected with inserted bar 13 on diaphragm 5 diapire, inserted bar 13 and ejector pin 4 crisscross distribution make inserted bar 13 can insert in the montant 3 that does not set up screw rod 11, make the connection between diaphragm 5 and the montant 3 more firm. Be connected with horizontally gusset plate 19 at 3 lateral walls of montant, the gusset plate 19 structure is the same with the structure of diaphragm 5, and the connection of 19 both ends of gusset plate makes montant 3 more firm on the wallboard, and gusset plate 19 connects in the balcony outside, and the people can not touch gusset plate 19 when leaning on the balcony guardrail, and gusset plate 19 is connected with montant 3 middle part, has the take the altitude between gusset plate 19 and the floor, can not suffer to trample under the normal use. The installation model is IRM-H638T TR2 infrared inductor 7 on gusset plate 19, enters into the induction zone in infrared inductor 7 top when the people, and infrared inductor 7 can send a signal and feed back the control mainboard, and control mainboard control servo motor 6 rotates, makes screw rod 11 rotate, makes montant 3 support diaphragm 5 upwards to slide, can promote the high 500mm of railing, can avoid climbing the accident that the railing caused.

The wall plate surface is provided with a groove 14, the groove 14 and one end of the transverse plate 5 are located in the same vertical plane, an alarm 8 is placed in the groove 14, supporting plates 15 are arranged at the upper end and the lower end of the alarm 8, the supporting plates 15 are located in the groove 14, a press-type switch 16 is arranged on the side wall of the alarm 8, the switch 16 is close to the outer side of the groove 14, an inclined pressing plate 17 is connected between the two supporting plates 15, the bottom end of the pressing plate 17 is hinged to the supporting plate 15 below, a spring 18 is connected between the top end of the pressing plate 17 and the supporting plate 15 above, under normal conditions, the top end of the pressing plate 17 extends out of the groove 14, the pressing plate 17 is inclined and does not contact with the switch 16, when the railing automatically ascends, the transverse plate 5 can be in sliding contact with the pressing plate 17 in the ascending process.

When the artificial climbing guardrail, trample the climbing in-process, infrared inductor 7 can sense and feed back the control mainboard in time, makes guardrail automatic lifting and sends the police dispatch newspaper, can remind dangerous action. The automatic reverse rotation interval time of the servo motor 6 can be set to be 5-10 minutes through the control main board, after the interval time, the control main board can drive the servo motor 6 to rotate reversely, the ejector rod 4 and the transverse plate 5 slide downwards to reset, and the alarm 8 is closed after the pressing plate 17 resets. When the infrared induction area or other circumstances make railing automatic lifting, the accessible is manual to be pressed the adjustment button on the control mainboard, makes servo motor 6 reversal, and ejector pin 4 gliding, can manual regulation make the guardrail reset, and siren 8 closes.

In the clearance between children's body sandwich montant 3, infrared inductor 7 can sense the signal in time and feed back the control mainboard, make guardrail automatic lifting and open siren 8, because ejector pin 4 is crisscross setting, the head of a family hears the alarm after, can upwards hold up children, pulls out children from the clearance between the ejector pin 4. When the automatic lifting guardrail is not needed, the infrared sensor 7 can be closed.

Here, it should be noted that: the infrared sensor 7 feeds back signals to the control main board, and the servo motor 6 is controlled to rotate by the control main board, which are the prior art, and have many applications in life, and are not the invention point of the present patent application, so the description is not provided in the application document.

The working principle is as follows: through infrared inductor 7, with signal feedback to the control mainboard, the control mainboard makes servo motor 6 rotate, make bull stick 9 and bevel gear B12 rotate, bevel gear B12 meshes bevel gear A10, make bevel gear A10 and screw rod 11 rotate, ejector pin 4 upwards slides along screw rod 11, ejector pin 4 upwards slides and drives top diaphragm 5 upwards to slide, improve railing height, and diaphragm 5 upwards slides in-process, diaphragm 5 tip and the one end sliding contact that clamp plate 17 stretches out recess 14, and extrude the clamp plate 17 top to the recess 14 in, make clamp plate 17 extrude siren 8 switch 16, open siren 8, send out the police dispatch newspaper. Set up the automatic reversal interval time of servo motor 6, after the interval time, the control mainboard can drive servo motor 6 antiport automatically, makes ejector pin 4 and diaphragm 5 reset. The top rod 4 and the transverse plate 5 can be manually controlled to descend by controlling an adjusting button on the main board. When the transverse plate 5 descends, the pressing plate 17 is reset by the elastic force of the spring 18, and the pressing plate 17 is far away from the switch 16 of the alarm 8, so that the alarm is stopped.

In the present invention, unless otherwise expressly stated or limited, "above" or "below" a first feature means that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact with each other via another feature therebetween. Also, the first feature being "on," "above" and "over" the second feature includes the first feature being directly on and obliquely above the second feature, or merely indicating that the first feature is at a higher level than the second feature. A first feature being "under," "below," and "beneath" a second feature includes the first feature being directly under and obliquely below the second feature, or simply meaning that the first feature is at a lesser elevation than the second feature.

The foregoing shows and describes the general principles, essential features, and advantages of the invention.
