Description

Technical Field

[0001] This utility model belongs to the field of road guardrail technology, and in particular relates to an adjustable road guardrail. Background Technology

[0002] Road guardrails (also called traffic guardrails or barriers) are facilities used to protect traffic safety and prevent vehicles, pedestrians, or other vehicles from entering dangerous areas or deviating from their normal driving routes. They are usually installed on both sides or in the middle of roads, especially on highways, bridges, tunnels, and curves. The design and materials of guardrails depend on the application and the required safety standards.

[0003] A common type of guardrail installed in the middle of the road. Some guardrails are set at a certain height to prevent pedestrians from climbing over, but they can also affect the left front view of drivers of vehicles on the left side of the road, especially at intersections. In order to increase the field of vision at intersections, a customized inclined guardrail structure is usually used to ensure the openness of the field of vision at intersections.

[0004] However, since the guardrail needs to be customized in size or use a fixed model, the tilt angle of the guardrail will also change according to the traffic volume at the intersection. For example, the visibility at intersections with high traffic volume will be set to be wider, while the length of the tilted guardrail at the end can be appropriately reduced to control the laying cost. Traditional fixed guardrails cannot adapt flexibly.

[0005] To address the aforementioned issues, this application proposes an adjustable road guardrail. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable road guardrail that solves the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is an adjustable road guardrail, comprising a lower horizontal bar horizontally arranged on the main body and a long side bar vertically arranged on the upper end of one side of the lower horizontal bar. The other upper end of the lower horizontal bar has vertically distributed short side bars. The guardrail body also includes guardrail posts. It further includes: an upper horizontal bar rotatably hinged to the long side bar, allowing the upper end of the guardrail to form slopes of different angles by changing the angle of the upper horizontal bar; a support rod movably connected between the upper horizontal bar's hinged end and the lower horizontal bar, allowing the tilt angle of the upper horizontal bar to be changed when the support rod moves; an upper track fixed to the upper horizontal bar and allowing the upper end of the support rod to slide; and a lower track fixed in an inclined state between the top of the short side bars and the lower horizontal bar and allowing the lower end of the support rod to slide.

[0009] Furthermore, both ends of the support rod on the same side are fixed with adjusting rods, and the two adjusting rods slide through the upper and lower tracks in a detachable manner.

[0010] Furthermore, the front end of the adjusting rod that passes through the upper and lower rails is provided with a threaded structure that mates with the locking sleeve. A screw wheel is fixed on the locking sleeve. The locking sleeve, through its mate with the threaded structure, presses the upper and lower ends of the support rod onto the upper and lower rails respectively.

[0011] Furthermore, the support rod is in a vertical position and moves along the inclined path of the lower track.

[0012] Furthermore, the support rod is provided with a positioning plate that slides against the upper part of the lower track on one side of the adjusting rod, and a positioning block is provided between the upper adjusting rod and the locking sleeve.

[0013] Furthermore, the positioning block includes a protrusion that slides against the lower part of the upper track and a through hole that passes through and is sleeved on the outside of the adjusting rod.

[0014] Furthermore, a rubber pad is provided at the contact position between the positioning block and the side of the upper track to increase the clamping friction.

[0015] This utility model has the following beneficial effects:

[0016] This utility model has one side of the short side bar facing the intersection, and the tilt angle of the entire guardrail can be adjusted by the rotation angle of the upper crossbar hinged on the long side bar, so as to adapt to the tilt angle requirements of different intersections, and the adaptability and flexibility are effectively improved.

[0017] In this utility model, the adjustment and use are ensured by the movement of the support rod on the upper and lower rails, and the locking sleeve is used to tighten it.

[0018] The positioning plate integrally formed at the front end of the support rod and cooperating with the lower rail, and the positioning block pressed by the locking sleeve and cooperating with the upper rail, both of these in this utility model improve the stability between the support rod and the upper and lower rails, while not affecting the ease of use of the locking sleeve.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0031] Please see Figure 1-6As shown, this utility model is an adjustable road guardrail, including a lower horizontal bar 11 horizontally arranged on the main body and a long side bar 12 vertically arranged on the upper end of one side of the lower horizontal bar 11. A short side bar 14 is vertically distributed on the upper end of the other side of the lower horizontal bar 11. The guardrail body also has guardrail bars 15. It further includes: an upper horizontal bar 13 rotatably hinged to the long side bar 12, allowing the upper end of the guardrail to form slopes of different angles by changing the angle of the upper horizontal bar 13; a support rod 2 movably connected between the lower horizontal bar 11 and the end of the upper horizontal bar 13 furthest from the hinge, allowing the support rod 2 to change the tilt angle of the upper horizontal bar 13 when it moves; an upper track 3 fixed to the upper horizontal bar 13 and allowing the upper end of the support rod 2 to slide; and a lower track 4 fixed in an inclined state between the top of the short side bar 14 and the lower horizontal bar 11 and allowing the lower end of the support rod 2 to slide. In this embodiment, the angle formed by the hinge of the upper horizontal bar 13 is adjustable to meet diverse needs.

[0032] In this embodiment, the support rod 2 has two adjustable rods 21 fixed at both ends on the same side. The two adjustable rods 21 slide through the upper rail 3 and the lower rail 4 in a detachable manner. In this embodiment, the end of the adjustable rod 21 near the support rod 2 has a smooth part that slides with the upper rail 3 and the lower rail 4 to ensure the flexibility of the support rod 2 in moving between the upper rail 3 and the lower rail 4 after the locking sleeve 5 is released.

[0033] The adjusting rod 21 has a threaded structure at the front end that passes through the upper rail 3 and the lower rail 4 and cooperates with the locking sleeve 5. The locking sleeve 5 is fixed with a screw wheel 51. The upper and lower ends of the support rod 2 are pressed onto the upper rail 3 and the lower rail 4 respectively by the locking sleeve 5 cooperating with the threaded structure. In this embodiment, the screw wheel 51 at the rear end of the locking sleeve 5 can also be a hexagonal head, an internal hexagonal head, etc.

[0034] In this embodiment, the support rod 2 is in a vertical state and moves along the inclined path of the lower track 4. By moving the support rod 2 along the inclined path of the lower track 4, one end of the upper crossbar 13 can be hinged and rotated, so that the structures can be connected to each other and the adjustment purpose can be achieved.

[0035] Among them, the support rod 2 is provided with a positioning plate 22 that slides and fits against the upper part of the lower track 4 on one side of the adjusting rod 21. A positioning block 6 is provided between the upper adjusting rod 21 and the locking sleeve 5. In this embodiment, the lower track 4 is always kept in a vertical state by the sliding of the positioning plate 22 against the lower track 4, which also improves the connection stability between the lower end of the support rod 2 and the lower track 4.

[0036] The positioning block 6 includes a protrusion 61 that slides against the lower part of the upper track 3 and a through hole 62 that passes through and is sleeved on the outside of the adjusting rod 21. In this embodiment, the positioning block 6 is provided with a through hole 62 to cooperate with the upper track 3, and can rotate freely when the positioning block 6 is not locked, so that it can rotate adaptively after the positions of the support rod 2 and the upper track 3 change. When the positioning block 6 is pressed, it can provide good stability.

[0037] The positioning block 6 is provided with a rubber pad 63 at the contact position with the side of the upper rail 3 to increase the pressing friction. In this embodiment, the rubber pad 63 can be pressed against the side of the upper rail 3 after the locking sleeve 5 and the adjusting rod 21 are screwed together. Then, through the through hole 62 and the support of the upper rail 3, the stability between the upper end of the support rod 2 and the upper rail 3 is ensured after the locking sleeve 5 is locked.

[0038] Understandably, by making the upper crossbar a rotatable structure, the tilt angle of the upper end of the guardrail can be changed, which increases the flexibility and adaptability in practical applications. Secondly, the use of locking sleeves for clamping can ensure stability while facilitating adjustment. Finally, the positioning plates and positioning blocks play a stabilizing role at the connection between the support rod and the upper and lower rails, thus ensuring the structural stability of the entire guardrail while making it adjustable.

[0039] One specific application of this embodiment is: to... Figure 1-3 The status shown has been adjusted to Figure 4 In this state: simultaneously loosen both locking sleeves 5 so that the positioning block 6 can rotate outside the adjusting rod 21. By moving the support rod 2 to the right, the adjusting rods 21 at the upper and lower ends of the support rod 2 slide inside the upper rail 3 and the lower rail 4 respectively. The positioning plate 22 slides against the lower rail 4, and the protrusion 61 slides against the lower end of the upper rail 3. The positioning block 6 rotates adaptively outside the adjusting rod 21 following the displacement of the upper rail 3.

[0040] After the support rod 2 is adjusted to the appropriate position, the locking sleeve 5 is tightened by the screw wheel 51. The lower end of the support rod 2 is pressed against the side of the lower rail 4, and the upper end of the support rod 2 and the positioning block 6 are pressed against the upper rail 3.

[0041] The presence of positioning block 6 and adjusting rod 21 ensures the stability of the guardrail structure while allowing for adjustment.
