Description

Technical Field

[0001] This utility model relates to the field of traffic facility technology, and in particular to a foldable mobile road barrier. Background Technology

[0002] Mobile roadblocks in existing technology are mainly divided into two categories: fixed roadblocks and simple movable roadblocks. 1. Fixed road barriers (such as concrete barriers): The structure is a monolithic solid concrete pouring, which has the advantages of large weight and good stability, but the volume is fixed and cannot be folded, it occupies a lot of space during transportation, the quantity transported at one time is small, and the handling requires large machinery, which is not flexible. 2. Simple movable road barriers (such as plastic warning road barriers): These are mostly hollow plastic structures that can be stacked but lack a folding design, limiting their stacking height. They also have low structural strength and are easily damaged by external impacts, failing to meet the isolation requirements for areas with heavy-duty vehicles. The core technical problems of existing technologies are: ① Large space occupation during transportation / storage, resulting in high logistics and warehousing costs; ② Inability to balance structural stability and portability; ③ Cumbersome folding / storage operations and lack of suitable folding structure designs. Utility Model Content

[0003] To address the aforementioned problems, this utility model aims to provide a foldable mobile roadblock to solve the problem that existing roadblocks cannot be folded, achieving the goals of lightweight, low cost, rapid assembly and folding storage, while maintaining structural stability.

[0004] The technical problem solved by this utility model can be achieved by the following technical solution: A foldable mobile roadblock includes a base, a middle support, and a folding rod. The middle support is located above the base, and an insert block is provided on the upper part of the base. The middle support has an arc-shaped groove and an insert block moving groove. The upper end of the insert block moving groove is connected to the arc-shaped groove, and the insert block is located in the insert block moving groove. Each end of the arc-shaped groove has a lug, and the lug is fixedly connected to a fixing screw by a thread. The lower end of the folding rod has a cylindrical rotating shaft, which is located in the arc-shaped groove and between the two lugs.

[0016] Combined with appendix Figures 1 to 9 As shown, this embodiment discloses a foldable mobile roadblock, including a base 1, a middle support 2, and a folding rod 3. The middle support 2 is disposed above the base 1. An insert 11 is disposed on the upper part of the base 1. The middle support 2 is provided with an arc-shaped groove 22 and an insert moving groove 21. The upper end of the insert moving groove 21 is connected to the arc-shaped groove 22. The insert 11 is located in the insert moving groove 21. Each end of the arc-shaped groove 22 is provided with a lug 23. The lug 23 is fixedly connected to the fixing screw 4 by threads. The lower end of the folding rod 3 is provided with a cylindrical rotating shaft 31. The rotating shaft 31 is disposed in the arc-shaped groove 22 and is located between the two lugs 23. Both ends of the rotating shaft 31 are provided with rotating grooves 33. The inner end of the fixing screw 4 extends into the rotating groove 33. The rotating shaft 31 is provided with a slot, and the insert 11 is inserted into the slot.

[0017] The slot includes a vertical slot 34, a locking groove 35, and a horizontal slot 36. The vertical slot 34 and the horizontal slot 36 are perpendicular to each other. The locking groove 35 is located between the vertical slot 34 and the horizontal slot 36. The vertical slot 34, the locking groove 35, and the horizontal slot 36 are interconnected. The upper end of the insert 11 is provided with a locking hook. The insert 11 is in the shape of an inverted L. When the folding rod 3 is in the folded state, the locking hook of the inverted L-shaped insert 11 is engaged with the locking groove 35.

[0018] A rotary spring 32 is installed within the rotating groove 33. One end of the rotary spring 32 is connected to the rotating groove 33 of the rotating shaft, and the other end is connected to the fixing screw 4. The rotation of the rotary springs 32 at both ends of the rotating shaft is controlled by the rotation. A spring 12 is installed between the base 1 and the intermediate support 2. The spring 12 is sleeved on the outside of the insert block 11. The lower end of the spring 12 is fixedly connected to the base 1, and the upper end contacts the lower surface of the intermediate support 2. The width of the insert block moving groove 21 is greater than the width of the insert block 11 to ensure that the insert block 11 can move.

[0019] A side groove 37 is provided on one side of the connection between the folding rod 3 and the pivot 31. When the folding rod is in the folded state, the side groove 37 is connected to one side of the arc groove 22 of the middle support seat 2, so that the folding rod 3 does not squeeze or collide with the arc groove 22 in the horizontal state.

[0020] The base 1 has three parallel inserts 11, and the rotating shaft 31 has three parallel slots. The middle insert is a raised inverted L-shaped insert, which locks the folded shape. The two sides of the inverted L-shaped insert 11 are cuboid inserts without locking hooks at the ends, which serve to position and fix the inserts 11. The inserts 11 are fitted and locked to the corresponding slots on the rotating shaft 31. The locking hooks of the inverted L-shaped inserts have beveled surfaces to ensure a secure lock. The width of the insert moving groove 21 is greater than the overall width of the insert 11, ensuring that the insert 11 can move within the groove during the unfolding of the folding rod.

[0021] The bottom of the base 1 is provided with anti-slip texture, and a counterweight is installed inside the base 1 to prevent tipping and increase stability. The folding rod 3 is covered with reflective stickers to enhance nighttime warning effect.

[0022] When folding, first pull the folding rod 3 and the intermediate support 2 upwards together, causing the insert 11 to disengage from the vertical slot 34. Rotate the folding rod 3 90 degrees to make it parallel to the ground. At this time, the return spring 32 is compressed. Then, the intermediate support 2 and the folding rod 3 move downwards together, causing the insert 11 to insert into the horizontal slot 36. Then, move the intermediate support 2 horizontally, causing the locking hook at the upper end of the insert 11 to insert into the locking groove 35. At this time, the spring between the base 1 and the intermediate support 2 is compressed. After releasing, a small portion of the spring at the rear of the intermediate support 2 returns to its original position. Under the action of the spring, the locking hook of the insert 11 locks with the locking groove 35, preventing the insert 11 from disengaging from the slot, thus locking the folding rod 3. In the locked state, under the action of the return spring 32, the folding rod 3 can only rotate 5 degrees.

[0023] When unfolding, first press down on the middle support 2, then move the middle support 2 horizontally to disengage the locking hook at the upper end of the insert 11 from the locking groove 35 (e.g., Figure 8(As shown), then lift the folding rod 3 and the middle support 2 upwards to separate the insert 11 from the horizontal slot 36, releasing the locking state of the folding rod 3. At this time, the rotary spring 32 returns to its original position. Under the action of the rotary spring 32, the folding rod 3 automatically changes from the horizontal state to the vertical state. Then insert the insert 11 into the vertical slot 34 to fix the folding rod 3.

[0024] The base 1 is made of HDPE through one-piece injection molding, and the bottom is a disc-shaped counterweight structure (filled with quartz sand, weighing 5kg); the middle support 2 is made of ABS+20% glass fiber reinforced plastic; the folding rod 3 is made of ABS+15% glass fiber reinforced plastic.

[0025] This utility model has the following features: 1. Significant weight reduction effect The overall weight is reduced to 35-40kg, which is more than 50% lighter than the original steel structure solution (over 80kg) and 80% lighter than traditional concrete roadblocks (over 200kg). It can be directly transported and deployed by a single person without any auxiliary equipment, further reducing labor costs.

[0026] 2. Manufacturing costs have been significantly reduced. Material costs: The unit price of engineering plastics (HDPE / ABS / PP) is only 1 / 3 to 1 / 2 of that of steel, and the cost of silica sand for weighting is 1 / 5 of that of polyurethane, resulting in an overall material cost reduction of 60%. Processing costs: One-piece injection molding replaces welding and multi-part assembly, reducing processing steps by 40%, increasing mold production efficiency by 3 times, and reducing the processing cost per piece by 55%; Overall cost: The total cost is reduced by 58%-65% compared to the steel structure solution and by more than 70% compared to traditional roadblocks, demonstrating a significant cost-performance advantage.

[0027] 3. Maintains advantages in space utilization and ease of operation. When folded, its volume remains 20% of its unfolded state, and a single light truck can transport up to 80 units (a 60% increase compared to the original steel structure solution of 50 units), reducing storage space usage by 80%. Folding / unfolding operations require no tools and can be completed by a single person within 40 seconds, increasing deployment efficiency by 4 times compared to traditional roadblocks.

[0028] 4. Balancing practicality and durability Engineering plastics are weather-resistant, corrosion-resistant, and anti-aging (service life ≥ 5 years). The built-in metal core strengthens key stress-bearing parts. When unfolded, it resists side impact force ≥ 600N and can withstand impacts from common scenarios such as low-speed collisions of small vehicles and pedestrian congestion without deformation or damage. The reflective design enhances the nighttime warning effect and is suitable for use in multiple scenarios.

[0029] This utility model is suitable for various scenarios: (1) Transportation After folding, 10 units can be stacked in a single layer, and 8 layers can be stacked in a light truck compartment, with 80 units transported at a time. No additional fixing is required during transportation (the plastic surface is non-slip and the stacking is stable), and the transportation cost is reduced by 40% compared to the original steel structure solution.

[0030] (2) On-site deployment phase A single person can carry a folding roadblock (5kg) from the carriage to the edge of the construction area, unfold it and lock the wheel set within 40 seconds, and place it continuously along the construction area to form a barrier. No hoisting equipment is required, and one person can complete the deployment within a 50-meter range in 0.5 hours, which is 5 times more efficient than traditional roadblocks.

[0031] (3) Usage process The "H"-shaped protective surface, combined with reflective stickers, provides a clear warning effect at night and can effectively prevent pedestrians and non-motorized vehicles from accidentally entering the construction area. When the folding pole 3 is unfolded, it forms a stable protective structure with a side impact resistance of ≥600N. It can withstand low-speed collisions (≤5km / h) with electric vehicles without damage, meeting the needs of conventional construction isolation.

[0032] (4) Recycling and storage After construction, it can be quickly folded and recycled by a single person. Its volume is 20% of the unfolded state, and its weight is only 5kg. It can be stacked directly, taking up little space and saving 90% of storage area compared to traditional roadblocks.

[0033] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the utility model. Any simple modifications, equivalent changes, or alterations made to the above embodiments based on the technical principles of the present utility model shall still fall within the scope of the technical solution of the present utility model.
