Description

Technical Field

[0001] The utility model relates to the technical field of roadblocks, in particular to an adjustable roadblock. Background Art

[0002] Roadblocks are obstacles that block road traffic and often serve to warn pedestrians and vehicles. They are usually used to warn pedestrians and vehicles during road construction and to control the entry and exit of vehicles at special intersections. Roadblocks seen in daily life are usually low in height and light in weight, and cannot play a good blocking role. Announcement No.: CN213571490U discloses a roadblock, including a base, the base is a hollow structure with an opening, the opening is located at the lower end of the base, the hollow structure of the base forms an inner cavity, a sponge for absorbing water is installed in the inner cavity, a sealing plate for closing the opening is installed on the base, a through hole for supplying water into the inner cavity is opened at the lower side of the base, the through hole is located above the sealing plate, an extrusion mechanism for squeezing the sponge is provided on the base, and a plurality of pads are fixedly connected to the lower end of the base. The utility model has the advantage that the roadblock is not easily washed away by the water on the road surface, thereby effectively reminding passing vehicles. However, when using the above technology, only the impact of road water on roadblocks is taken into account, but the impact of human factors is not taken into account. In daily life, some pedestrians choose to climb over or move roadblocks in order to take a shortcut, making the roadblocks unable to play a blocking role, posing a huge safety hazard, and therefore needs to be improved.

[0012] 1. In the utility model, by providing a heightening plate, a handle, a groove, a spring, a buckle, a round hole, and a push rod structure, the heightening plate can be raised to increase the overall height of the roadblock, effectively avoiding the potential safety hazard of pedestrians climbing over the roadblock in order to take a shortcut. By providing a counterweight groove, a cover plate, and a handle structure, the weight of the roadblock can be increased by adding a counterweight, thereby improving the stability of the roadblock and effectively preventing it from being moved by pedestrians who take a shortcut.

[0013] 2. In the utility model, by setting the main ventilation holes, auxiliary ventilation holes and drainage grooves, the influence of weather factors on the roadblocks is reduced and the stability of the roadblocks is improved. By setting the right mounting rod, the left mounting rod, the connecting holes, the bolts and the nut structures, the roadblocks can be connected according to different terrains to achieve the required length, ensuring that each roadblock can be stably connected.

[0024] Embodiment 1

[0025] See also Figure 1 , Figure 3 , Figure 4 and Figure 6The utility model provides a technical solution: an adjustable roadblock, comprising a base 1 and a heightened plate 2, and the heightened plate 2 is located inside the base 1, a handle 3 is fixedly connected to the top of the heightened plate 2, a groove 4 is provided inside the heightened plate 2, a spring 5 is fixedly installed inside the groove 4, a buckle 6 is fixedly installed at one end of the spring 5 away from the bottom of the groove 4, a round hole 7 is provided on the side of the base 1, a push rod 8 is slidably connected inside the round hole 7, the heightened plate 2 and the handle 3 are both made of aluminum alloy, while ensuring the firmness of the heightened plate 2, the weight of the heightened plate 2 is reduced, and the heightened plate 2 is convenient to lift when in use, effectively avoiding the potential safety hazard of pedestrians choosing to climb over the roadblock in order to take a shortcut, the groove The position of 4 corresponds to the position of the circular hole 7, so that the spring 5 in the groove 4 pushes the buckle 6 to insert into the circular hole 7, thereby improving the stability between the base 1 and the height-increasing plate 2. There are two groups of buckles 6, which are symmetrically distributed inside the height-increasing plate 2. There are two groups of push rods 8, which are symmetrically distributed inside the base 1, so that the push rods 8 can be used to push the buckles 6 and retract the height-increasing plate 2 into the base 1. A counterweight groove 9 is provided on the surface of the base 1, and a cover plate 10 is rotatably connected to the top of the counterweight groove 9. A handle 11 is provided on the surface of the cover plate 10, so as to add a counterweight to the roadblock, increase the weight of the roadblock, make the roadblock more stable, and effectively prevent it from being moved by pedestrians who take shortcuts.

[0026] Embodiment 2

[0027] See also Figure 2 , Figure 5 A right mounting rod 12 and a left mounting rod 13 are fixedly connected to both sides of the base 1. A connecting hole 14 is provided on the surface of the right mounting rod 12. A bolt 15 is connected inside the connecting hole 14. A nut 16 is connected to the bottom of the bolt 15, so that the roadblocks can be connected together according to different terrains to achieve the required length. Ventilation holes 17 are provided on the surface of the base 1, and a drainage groove 18 is provided at the bottom of the base 1 to increase ventilation and drainage channels, so as to reduce the influence of weather factors on the stability of the roadblock.

[0028] Working principle: When using the adjustable roadblock, first, pull up the handle 3, and the height-increasing plate 2 begins to rise. When the position of the buckle 6 coincides with the circular hole 7, the spring 5 of the buckle 6 releases the pressure, pushes the buckle 6 to insert into the circular hole 7, and pushes the push rod 8 to move outward. The buckle 6 is completely fitted with the circular hole 7. At this time, the height-increasing plate 2 is fully raised, the height of the roadblock is increased, and pedestrians are effectively prevented from choosing to climb over the roadblock in order to take a shortcut. Subsequently, the handle 11 is pulled to open the cover 10, and a counterweight is added to the counterweight slot 9, and then the cover 10 is closed. When the two roadblocks are connected, the right mounting rod 12 is aligned with the left mounting rod 13, and a suitable connecting hole 14 is selected, and the bolt 15 is tightened into the nut 16. At this time, the roadblock is completely connected. By increasing the height and weight of the roadblock, the safety hazard of some pedestrians choosing to climb over or move the roadblock in order to take a shortcut is effectively avoided. At the same time, by increasing the ventilation and drainage channels, the influence of weather factors on the stability of the roadblock is reduced.
