Description

Technical Field

[0001] This utility model belongs to the field of electric guardrail technology, specifically relating to a telescopic electric guardrail. Background Technology

[0002] In the field of road traffic, retractable electric guardrails are widely used in scenarios such as road separation, lane marking, and temporary traffic control. They can be adjusted in length according to the actual needs of the road, effectively separating vehicles and pedestrians, improving traffic safety, and are also widely used at parking lot entrances and exits.

[0003] Chinese patent CN216194326U discloses a telescopic electric guardrail, comprising a chassis, a bracket mounted on the top of the chassis, a connecting frame mounted on the inner side of the bracket, a guardrail mounted on one side of the bracket, a longitudinal plate mounted on the inner side of the guardrail, and a fitting frame mounted on the inner side of the guardrail. This invention utilizes a movable groove to support a connecting rod. Workers can pull the rod out of the through hole to release the fixing plate, and then push the gate frame, causing the gate frame to rotate around the connecting rod within the movable groove. This allows the gate frame to rotate along with the inner fence, creating an opening for pedestrians to pass through without opening the entire device, providing convenience.

[0004] Although the aforementioned device can create a gap in the guardrail for pedestrians to pass through by having workers pull out the bolts, the guardrail cannot rotate or rise while pedestrians are crossing. This means that vehicles must wait for pedestrians to pass by, making it very inconvenient in actual use. Utility Model Content

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figures 1-4 As shown, this utility model provides a telescopic electric guardrail, including a gate body 1, a guardrail mechanism 2 installed on one side of the gate body 1, and auxiliary mechanisms 3 evenly arranged on both sides of the guardrail mechanism 2.

[0024] The guardrail mechanism 2 includes an upper horizontal bar 21 and a lower horizontal bar 25, as well as a connecting component 29 located between the upper horizontal bar 21 and the lower horizontal bar 25. Both sides of the upper horizontal bar 21 and the lower horizontal bar 25 are fixedly connected with evenly distributed convex shafts 28. The guardrail mechanism 2 is used to allow vehicles and pedestrians to pass.

[0025] The auxiliary mechanism 3 includes a column 31, a linkage column 33, and an auxiliary plate 32. One end of the auxiliary plate 32 is rotatably connected to the bottom end of the column 31. The linkage column 33 is inserted into the bottom of the column 31. A transmission plate 38 is movably connected above the auxiliary plate 32. The column 31 is penetrated by a protruding shaft 28. The auxiliary mechanism 3 is used to provide auxiliary support and enhance the strength against impact. The protruding shaft 28 penetrates the column 31, causing the gate body 1 to fold together when the entire guardrail mechanism 2 rotates up or down. This is existing technology.

[0026] In a further embodiment, a drive motor 23 is installed inside the upper crossbar 21, an upper telescopic rod 22 is slidably connected to the lower part of the upper crossbar 21, a lower telescopic rod 26 is slidably connected to the upper part of the lower crossbar 25, a lead screw 24 is rotatably connected inside the upper crossbar 21, the lead screw 24 passes through and is threaded to one end of the upper telescopic rod 22, and one end of the lead screw 24 is connected to the output end of the drive motor 23 via a belt, and the connecting assembly 29 is located between the upper telescopic rod 22 and the lower telescopic rod 26.

[0027] In this embodiment, a limiting plate is fixed to one end of the upper telescopic rod 22. The plate is threaded through by the lead screw 24 and the plate also limits the telescopic range of the upper telescopic rod 22. In addition, there are limit rods inside the upper crossbar 21 and the lower crossbar 25. The limit rods pass through one end of the upper telescopic rod 22 and one end of the lower telescopic rod 26, respectively, to limit the sliding direction and the strength after sliding. The upper crossbar 21 and the lower crossbar 25 are provided with grooves corresponding to the upper telescopic rod 22 and the lower telescopic rod 26. The lead screw 24 and the limit rods mentioned above are located in the grooves.

[0028] In a further embodiment, the connecting component 29 includes an upper connecting post 291 and a lower connecting post 294. The upper end of the upper connecting post 291 is movably connected to the interior of the upper telescopic rod 22, and the lower end of the lower connecting post 294 is movably connected to the interior of the lower telescopic rod 26. A through groove 293 is provided at the lower end of the upper connecting post 291, and a protrusion 295 is fixedly connected to one side of the upper end of the lower connecting post 294. The protrusion 295 is slidably connected inside the through groove 293.

[0029] In this embodiment, the lower end of the upper telescopic rod 22 and the upper end of the lower telescopic rod 26 have grooves at the corresponding positions of the upper connecting post 291 and the lower connecting post 294, so that the upper connecting post 291 and the lower connecting post 294 can be movably connected; the upper end of the upper connecting post 291 and the lower end of the lower connecting post 294 are movably connected to the same insertion shaft, so they can both rotate around the insertion shaft.

[0030] In a further embodiment, a lower connecting block 296 is fixedly connected to the top of the lower connecting post 294, and an upper connecting block 292 is fixedly connected to the bottom of the upper connecting post 291. The upper connecting block 292 is inserted into the interior of the lower connecting post 294, and the lower connecting block 296 is inserted into the interior of the upper connecting post 291.

[0031] In this embodiment, when the entire guardrail mechanism 2 is rotated and raised by the gate body 1, the upper connecting block 292 will be pulled out from the inside of the lower connecting column 294, and the lower connecting block 296 will be pulled out from the inside of the upper connecting column 291. This allows the upper connecting column 291 and the lower connecting column 294 to be extended, thereby adapting to the rotated upper crossbar 21 and lower crossbar 25. When the entire guardrail mechanism 2 is rotated and lowered by the gate body 1, the upper connecting block 292 will be reinserted into the inside of the lower connecting column 294, and the lower connecting block 296 will be reinserted into the inside of the upper connecting column 291. This allows the upper telescopic rod 22, the lower crossbar 25, and the connecting assembly 29 to form the guardrail.

[0032] In a further embodiment, the end of the upper telescopic rod 22 away from the upper crossbar 21 is fixedly connected to an inclined linkage 27, and the end of the lower telescopic rod 26 away from the lower crossbar 25 is slidably connected inside the linkage 27.

[0033] In this embodiment, the linkage 27 is composed of two plates and a roller. The roller rotates between the two plates via an axle and is in contact with the ground. One end of the lower telescopic rod 26 is slidably connected between the two plates of the linkage 27 via a protrusion, so that the entire protective plate will not be misaligned when it is rotated and folded. In addition, the roller facilitates the retraction of the upper telescopic rod 22 and the lower telescopic rod 26 between the upper crossbar 21 and the lower crossbar 25.

[0034] In a further embodiment, a rack 34 is fixedly connected above the linkage column 33, a spring 35 is fixedly connected above the rack 34, the top end of the spring 35 is fixedly connected inside the column 31, a gear 36 is meshed with one side of the rack 34, a rack 37 is meshed with the side of the gear 36 away from the rack 34, the upper end of the transmission plate 38 is movably connected to the bottom end of the rack 37, and the gear 36 is rotatably connected inside the column 31.

[0035] In this embodiment, the column 31 has mounting cavities at the corresponding linkage column 33, rack 34, spring 35, gear 36, and rack 37. Both ends of the transmission plate 38 and one end of the auxiliary plate 32 are movably connected to the convex shaft, and can rotate around the convex shaft to perform transmission. When the transmission plate 38 is not passively in contact with the ground, that is, when the guardrail mechanism 2 is rotated and lifted, the spring 35 will rebound and push rack 34 and linkage column 33 out of the interior of the column 31. During this process, rack 37 will move upward, thereby preventing the auxiliary plate 32 from unfolding.

[0036] In a further embodiment, the upper crossbar 21 and the lower crossbar 25 are installed at the output end of a rotary motor inside the gate body 1, near the gate body 1, to drive the entire guardrail mechanism 2 to rotate and lift.

[0037] In this embodiment, the gate body 1 is the body of a parking lot gate in the prior art, which has a drive motor inside that can rotate through the guardrail to allow pedestrians or vehicles to pass.

[0038] The working principle of this utility model is as follows: When pedestrians need to pass, the drive motor 23 inside the upper crossbar 21 can be operated by an external control device. At this time, the lead screw 24 will rotate, thereby causing the upper telescopic rod 22 to retract into the interior of the upper crossbar 21. At this time, the roller at the bottom of the linkage 27 will roll, and since the upper connecting block 292 at the bottom of the upper connecting column 291 is inserted into the interior of the lower connecting column 294, and the lower connecting block 296 at the top of the lower connecting column 294 is inserted into the interior of the upper connecting column 291, the upper connecting column 291 and the lower connecting column 294 become an integral column, thereby driving the lower telescopic rod 26 below the connecting assembly 29 to retract into the interior of the lower crossbar 25.

[0039] When a vehicle needs to pass, the motor inside the gate body 1 will rotate, thereby rotating one end of the upper crossbar 21 and the lower crossbar 25. At this time, because the upper telescopic bar 22 and the lower telescopic bar 26 have a certain height difference and their rotation centers are not aligned, the upper crossbar 21 will first rotate and move upward a certain distance along with the upper telescopic bar 22 and the lower upper connecting column 291. At this time, the lower connecting block 296 will disengage from the interior of the upper connecting column 291. Only then will the lower crossbar 25 rotate. When the entire guardrail mechanism 2 rotates to the highest point, the column 31 and the connecting component 29 are in a folded state.

[0040] When the vehicle is no longer moving in the opposite direction, the motor inside the gate body 1 will rotate in the opposite direction, and during the rotation and descent of the guardrail mechanism 2, since the column 31 is connected to the guardrail mechanism 2 through the convex shaft 28, after rotation, the linkage column 33 at the bottom of the column 31 will contact the ground, thereby inserting into the interior of the column 31. This will cause the gear 36 to rotate through the rack 34, and the rotation of the gear 36 will cause the rack 37 to be transported downward in the opposite direction. At this time, the auxiliary plate 32 will be unfolded from one side of the column 31 through the transmission plate 38, finally expanding the contact area between the column 31 and the ground and increasing the impact resistance.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
