[0024] Compared with the prior art, the present invention has the following advantages: the structure is scientific and reasonable, and the use is safe and convenient.

[0025] 1. A blocking folding rod slot seat, a folding rod slide slot, a folding rod arm slot, a folding rod slot, a spring base, a folding rod spring, a folding rod slide seat, a folding rod arm, a folding rod, a folding rod clip, a limit clip slot, a folding rod clip slot, a reset spring and a limit clip. The folding rod is fixed by clamping the limit clip at one end of the folding rod inside the limit clip slot. After the limit clip is clamped in the limit clip slot and removed, the reset spring will push the limit clip upward, and the limit clip will then drive the clip hidden in the folding rod slot. When the folding rod on the side is pushed upward, the stretched folding rod spring will shrink due to the loss of restraint and its own elastic reset ability. At that time, because the spring base is fixed, the folding rod spring will drive the folding rod slide to slide inside the folding rod slide groove. When the folding rod and the folding rod arm are kept vertical, the folding rod spring will be in a reset state. At that time, the folding frame will pop out from the top of the guardrail, so that the guardrail can increase the height. During use, the guardrail can be changed according to the height of the blocked object, which can increase the versatility of use of the device.

[0026] 2. A blocking rod, a guardrail vertical rod, a guardrail horizontal rod, a connecting rod, a lifting rod, a limiting block, a height-limiting guardrail horizontal rod, a height-limiting guardrail vertical rod, a height-limiting rod, an anti-collision rotating shaft and an anti-collision shaft slot seat are provided. The blocking rod and the height-limiting rod are connected to each other through the setting of the connecting rod. When the guardrail vertical rod and the guardrail horizontal rod are folded, the lifting rod will drive the height-limiting guardrail horizontal rod and the height-limiting guardrail vertical rod to fold together, and the setting of the limiting block can ensure that the lifting rod will not rotate in the opposite direction and can fix the lifting rod. One end of the blocking rod is embedded in the inner side of the anti-collision rotating shaft through the anti-collision rotating shaft, which can prevent people and vehicles passing by on the inside or outside of the railing from causing damage to the guardrail, thereby causing damage to the guardrail. Replacement will require a large amount of money investment, which reduces the practicality of the guardrail.

[0027] 3. A motor slide, a motor fixing seat, a flip motor, a motor limit frame, and a motor clamp are provided. The motor is fixed by embedding the flip motor into the inner side of the motor fixing seat, and then the motor fixing seat is slid and embedded into the inner side of the motor slide to complete the fixed installation of the motor. The installation position of the guardrail determines that it will inevitably face the possibility of being collided. The advantage of such installation is that when the support box is collided, the motor can be quickly taken out. If only the motor is damaged, only the motor needs to be replaced to complete the repair of the device, which can greatly improve the safety attributes of the device and greatly facilitate the maintenance and repair efficiency of the device. At the same time, the transmission end of the flip motor is also fixed by embedding it into the inner side of the motor clamp, which also facilitates the connection of the flip motor. The setting of the motor limit frame ensures the operating stability of the device and does not cause the guardrail to shake.

[0028] In summary, the present invention adds a heightened guardrail that can be quickly opened and folded to the structure of the traditional guardrail, making the guardrail applicable to a wider range of people and increasing the versatility of use of the device. At the same time, the device adopts a folding opening method to open, which makes the guardrail occupy a smaller area and makes the guardrail applicable to a wider range of places. It can also be used in some narrow places without wasting space. At the same time, considering the role of the guardrail, it is bound to encounter collisions. In order to avoid frequent replacement of the guardrail, an anti-collision mechanism is also provided, so that the guardrail can be protected to the maximum extent when encountering collisions on the inside and outside of the guardrail, reducing capital investment and increasing the practicality of the guardrail. Taking into account that the support box will be collided, the motor and the transmission mechanism are installed in an embedded connection manner, so that the guardrail can be quickly repaired and maintained.

A plurality of spring bases 206 and folding rod slides 208 are installed at the inner bottom end, one end of the spring base 206 is connected to a folding rod spring 207, and a folding rod support arm 209 is clamped on the top of the folding rod slide 208. The spacing between the plurality of spring bases 206 is the same, and the spacing between the plurality of spring bases 206 is the same as the height of the folding rod support arm 209. One end of the folding rod spring 207 is connected to the spring base 206, and a folding rod 210 is clamped on the top of the folding rod support arm 209. The two folding rods 210 have different shapes and sizes, and the two folding rods 210 are respectively embedded in the blocking folding rod slot 202 and the height-limiting folding rod slot 224;

[0046] In order to enable the height-increasing mechanism of the guardrail to be quickly fixed and unfolded, one end of the folding rod 210 is connected to a folding rod clip 211, and one end of the blocking folding rod slot 202 and the height-limiting folding rod slot 224 are both provided with a limit clip groove 212, and the outer surface of one end of the folding rod clip 211 is also provided with a limit clip groove 212, and a limit clip 215 is embedded in the inner side of the limit clip groove 212. One end of the blocking folding rod slot 202 and the height-limiting folding rod slot 224 are both provided with a folding rod clip groove 213, and a return spring 214 is installed inside the folding rod clip groove 213. One end of the guardrail cross bar 217 and the blocking rod 201 are both connected to the anti-collision rotating shaft 227;

[0047] The inner side of the support box 1 is connected to a support detection mechanism 3;

[0048] The support detection mechanism 3 includes a camera 301, a magnetic stripe induction coil 302, a flip box 303, a flip window 304, an anti-collision shaft slot seat 305, a blocking rod gear disc 306, a folding crossbar gear disc 307, a motor slide 308, a motor fixing seat 309, a flip motor 310, a motor limit frame 311, a motor snap ring 312, a driving gear pulley 313, a driving gear 314, a driven gear 315, a driven gear pulley 316, a belt 317, a gear disc fixing shaft 318, a gear fixing shaft 319 and a closing plate 320;

[0049] In order to realize intelligent recognition of the guardrail, two cameras 301 are installed on the top of the support box 1, the bottom end of the support box 1 is connected to the magnetic strip induction coil 302, and one end of the support box 1 is connected to the flip box 303. The flip end and the top of the flip box 303 are provided with a flip window 304. The inside of the flip box 303 is fixed with a blocking rod gear disc 306 and a folding cross bar gear disc 307 through a gear disc fixing shaft 318. One end of the blocking rod gear disc 306 and the folding cross bar gear disc 307 are connected to an anti-collision shaft slot seat 305, and the two anti-collision shaft slot seats 305 are both engaged with the anti-collision rotating shaft 227. Motor slide grooves 308 are provided at both ends of the inner side of the support box 1, and a motor fixing seat 309 is slidably embedded in the inner side of the motor slide groove 308, and a flip motor 310 is embedded in the inner side of the motor fixing seat 309;

[0050] In order to facilitate the assembly of the transmission mechanism of the guardrail, a motor limit frame 311 is installed on the driving end of the flip motor 310 on the inner side of the support box 1. One end of the inner side of the support box 1 is connected to a driving gear 314 and a driven gear 315 through a gear fixing shaft 319. The driven gear 315 is meshed with the folding cross bar toothed disc 307, and the driving gear 314 is meshed with the blocking rod toothed disc 306. The driving gear 314 is connected to the driving gear pulley 313 on one end surface, and the driven gear 315 is connected to the driven gear pulley 316 on one end surface. The driving gear 314 and the driven gear pulley 316 are both sleeved with a belt 317 on the inside. A closing plate 320 is installed at one end of the support box 1. The driving end of the flip motor 310 is embedded in the inner side of the motor retaining ring 312. The power input end of the flip motor 310 is connected to the power output end of the external control terminal. The two cameras 301 are facing opposite directions. The signal output ends of the cameras 301 and the magnetic stripe induction coil 302 are connected to the signal input end of the control terminal.

[0051] The working principle and usage process of the present invention are as follows: the operator first needs to collect the image information of people or vehicles that do not need to be blocked through the camera 301 and store it in the control terminal. Then, when the people or vehicles that have been collected pass through the guardrail, the information will first be collected by the camera 301 and then distinguished by the image acquisition card inside the control terminal. When the similarity rate reaches more than 85%, the motor controller will control the flip motor 310 to operate, so that the guardrail opens. When the similarity rate is less than 85%, the motor controller will not send a signal to the flip motor 310. In addition, a magnetic stripe induction coil 302 is installed at the bottom of the guardrail. When there is an object under the guardrail, the magnetic stripe induction coil 302 will send a normally open command to the motor controller, so that the guardrail will not be lowered when no people or vehicles pass by.

[0052] At the same time, the guardrail itself also has an increasing mechanism. The folding rod 210 is fixed by the limit card strip 215 at one end of the folding rod 210 being stuck in the inner side of the limit card strip groove 212. After the limit card strip 215 is stuck in the inner side of the limit card strip groove 212 and removed, the return spring 214 will push the limit card strip 215 upward. At this time, the limit card strip 215 will drive the folding rod 210 hidden in the inner side of the folding rod groove 205 to be pushed upward. Then, the straightened folding rod spring 207 will be pushed upward due to the loss of restraint and its own elastic return ability. At the same time, because the spring base 206 is fixed to the bottom end of the inner side of the folding rod slide groove 203, the folding rod spring 207 will pull the folding rod slide 208 to slide inside the folding rod slide groove 203 until the folding rod 210 and the folding rod support arm 209 are kept vertical. The folding rod spring 207 will be in a reset state, and the top of the guardrail will pop out of the folding frame, so that the guardrail can be increased in height. During use, the guardrail can be changed according to the height of the object being blocked, which can increase the versatility of use of the device.

[0053] The motor 310 is fixed by being embedded in the inner side of the motor fixing seat 309, and the motor fixing seat 309 is then slidably embedded in the inner side of the motor slide groove 308 to complete the fixed installation of the motor. The installation position of the guardrail determines that it will inevitably face the possibility of being collided. The advantage of such installation is that when the support box 1 is collided, the motor can be quickly taken out. If only the motor is damaged, only the motor needs to be replaced to complete the repair of the device, which can greatly improve the safety of the device and greatly facilitate the maintenance and repair efficiency of the device. At the same time, the transmission end of the flip motor 310 is also fixed by being embedded in the inner side of the motor clamping ring 312, which is more convenient for the connection of the flip motor 310. The setting of the motor limit frame 311 ensures the operating stability of the device and does not cause the guardrail to shake.

[0054] When the flip motor 310 rotates, it will drive the meshing blocking rod gear disc 306 and the driven gear 315 connected by the belt 317 to rotate together, and then the driven gear 315 will drive the meshing folding crossbar gear disc 307 to rotate. At this time, the blocking rod gear disc 306 and the folding crossbar gear disc 307 will drive the anti-collision shaft slot seat 305 to rotate upward, and then the anti-collision shaft slot seat 305 will drive the embedded anti-collision rotating shaft 227 to rotate together. When the anti-collision rotating shaft 227 rotates, the blocking rod 201 and the guardrail crossbar 217 connected to the anti-collision rotating shaft 227 rotate upward together, and at the same time drive the guardrail vertical bar 21 6 and the guardrail cross bar 217 are folded. When the guardrail vertical bar 216 and the guardrail cross bar 217 are folded, the lifting rod 219 will drive the height-limiting guardrail cross bar 221 and the height-limiting guardrail vertical bar 222 to fold together. The setting of the limit block 220 can ensure that the lifting rod 219 will not rotate in the opposite direction, and can fix the lifting rod 219. One end of the blocking rod 201 is embedded in the inner side of the anti-collision shaft slot seat 305 through the anti-collision rotating shaft 227, which can prevent people and vehicles passing by on the inside or outside of the guardrail from causing damage to the guardrail, thereby causing damage to the guardrail. Replacing it will cost a lot of money, which reduces the practicality of the guardrail.

[0055] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or substitute equivalents for some of the technical features. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
