[0016] 1. This utility model provides an adjustable road median barrier device, which employs a combination of a vertical rod, a connecting mechanism, an insert rod, a rotating rod, a mounting base, a guide cylinder, a rotating motor, a first gear, a mounting plate, a spring, a second gear, an electric push rod, and a rack. The rotating motor drives the insert rod to move up and down, thereby controlling whether the rotating rod is fixed in the mounting base.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-6 As shown, an adjustable road center guardrail device includes a central frame 1, two linkage mechanisms 2 are movably installed on the left and right sides of the central frame 1, vertical rods 3 are movably installed on the side of the two linkage mechanisms 2 that are far apart from each other, a support mechanism 4 is fixedly connected to the lower side of the two vertical rods 3, and a connecting mechanism 5 is movably sleeved on the inner side of the vertical rods 3.

[0027] The connecting mechanism 5 includes a plug rod 51. The outer side of the plug rod 51 is movably sleeved on the inner side of the left vertical rod 3. The inner side of the right vertical rod 3 is rotatably connected to two rotating rods 52 that are symmetrically distributed vertically. The inner side of the left vertical rod 3 is fixedly connected to two card seats 53 that are distributed vertically near the upper and lower sides. The outer sides of the two plug rods 51 are movably sleeved on each other at positions close to each other. The middle of the inner side of the left vertical rod 3 is fixedly connected to a rotating motor 55. The output end of the rotating motor 55 and the middle of the outer sides of the two guide cylinders 54 are fixedly connected to a first gear 56, and the two first gears 56 on the same side are meshed together.

[0028] It should be noted that the vertical rod 3 is equipped with a power storage component, a solar energy component, a remote control component, etc., for remote control. The rotating motor 55 drives the first gear 56 to rotate, and the rotation of the first gear 56 drives the guide cylinder 54 to rotate. The guide cylinder 54 is equipped with a spiral groove, and the outside of the insertion rod 51 is equipped with a slider that is slidably connected in the spiral groove, so that the insertion rod 51 moves up and down when the guide cylinder 54 rotates, so that the insertion rod 51 can be inserted into or disengaged from the inside of the rotating rod 52, thereby allowing multiple devices to be connected or disconnected. At the same time, the rotating rod 52 is made with a certain elastic structure, or a small part of it, so that the rotating rod 52 can remain straight, while bending at a certain point in the middle when force is applied to both sides. Therefore, when adjusting the spacing of the vertical rods 3, not all of the vertical rods 3 need to be raised.

[0029] like Figure 6 As shown, the support mechanism 4 includes a base 41, the upper side of which is fixedly connected to the lower side of the vertical rod 3. A telescopic motor 42 is fixedly connected to the middle of the inner side of the base 41. Four rectangularly distributed movable components 43 are movably installed on the inner side of the base 41 near the four corners.

[0030] It should be noted that the telescopic motor 42 can drive the base 41 to move up and down. The moving component 43 is equipped with rollers that can adjust the height, so that the telescopic motor 42 drives the base 41 to move up and down, and the moving component 43 lowers the rollers, causing the moving component 43 to drive the vertical rod 3 to move.

[0031] like Figure 6 As shown, a cleaning cylinder 44 is movably mounted on the underside of each of the four movable components 43.

[0032] It should be noted that the sweeping cylinder 44 is made of flexible material to protect the rollers on the moving component 43 and prevent garbage from affecting the operation of the rollers.

[0033] like Figure 6 As shown, a rubber pad is fixedly connected to the lower side of the telescopic motor 42.

[0034] It should be noted that the rubber pad is used to protect the telescopic motor 42, reduce the wear and tear on the telescopic motor 42 from the ground, and the rubber pad can be quickly replaced, resulting in low maintenance costs.

[0035] like Figure 5 As shown, the two rotating rods 52 are fixedly connected to the second gear 59 at positions far apart from each other. The inner side of the vertical rod 3 on the right side is fixedly connected to two electric push rods 510 that are symmetrically distributed vertically. The ends of the two electric push rods 510 that are far apart from each other are fixedly connected to racks 511. The right side of the rack 511 is meshed with the left side of the second gear 59.

[0036] It should be noted that the electric push rod 510 can drive the rack 511 to move up and down, causing the rack 511 to drive the second gear 59 to rotate, which in turn causes the second gear 59 to drive the rotating rod 52 to rotate.

[0037] like Figure 4 As shown, each of the two insert rods 51 is fixedly connected to a locking plate 57 on the side that is close to each other. The outer locking block of the locking plate 57 is slidably connected to the vertical groove opened on the inner side of the left vertical rod 3.

[0038] It should be noted that the clamping plate 57 is used to restrict the insertion rod 51, so that when the guide cylinder 54 rotates, the guide cylinder 54 cannot drive the insertion rod 51 to rotate synchronously.

[0039] like Figure 3 As shown, springs 58 are movably installed on the side of the two plates 57 that are close to each other.

[0040] It should be noted that the spring 58 is used to support the insertion rod 51, so that when multiple of these devices are connected together, the rotating motor 55 can be directly de-energized without maintaining the state of the guide cylinder 54. The spring 58 is used to push the insertion rod 51 to maintain its stable position.

[0041] The working principle of this utility model is as follows: First, the vertical rod 3 is equipped with a power storage component, a solar energy component, and a remote control component for remote control. The rotating motor 55 drives the first gear 56 to rotate, which in turn drives the guide cylinder 54 to rotate. The guide cylinder 54 has a spiral groove, and the outer side of the insertion rod 51 has a slider slidably connected to the spiral groove. This allows the insertion rod 51 to move up and down when the guide cylinder 54 rotates, enabling it to insert into or disengage from the inner side of the rotating rod 52. This allows multiple devices to be connected or disconnected. The electric push rod 510 drives the rack 511 to move up and down, causing the rack 511 to drive the second gear 59 to rotate, which in turn drives the rotating rod 52 to rotate. The rotating motor 55 drives the insertion rod 51 to move up and down, thus controlling whether the rotating rod 52 is fixed in the holder 53. Relying on the remote control system, it is possible to disconnect the device at any time along the central median barrier of an entire road, to cope with various emergencies, and to avoid the slow adjustment caused by the simultaneous movement of multiple devices required for tidal flow lanes. Finally, the telescopic motor 42 can drive the base 41 to move up and down. The moving component 43 is equipped with rollers that can adjust the height, so that the telescopic motor 42 drives the base 41 to move up and down. The moving component 43 lowers the rollers, causing the moving component 43 to move the vertical rod 3. The sweeping cylinder 44 is made of flexible material to protect the rollers on the moving component 43 and prevent garbage from affecting the operation of the rollers. The rotating rod 52 is made of a certain elastic structure, which allows the rotating rod 52 to remain straight while bending at a certain point in the middle when force is applied to both sides. This means that when adjusting the spacing of the vertical rods 3, not all of the vertical rods 3 need to be raised. The moving component 43 drives the vertical rods 3 to move, thereby adjusting the spacing between the two vertical rods 3. This allows the barrier to move directly to both sides after it is broken at a certain point in the road center. By compressing the length of a single device, the opening at the broken opening can be achieved, avoiding the problem of encroachment on the lanes on both sides caused by the difficulty in adjusting the overall length and the need for rotation.
