Description

Technical Field

[0001] The utility model relates to a guardrail, in particular to a guardrail for road construction. Background Art

[0002] During the construction process, guardrails are often needed. Guardrails can not only defend the perimeter of the construction, but also ensure the safety of construction workers. When using guardrails, it is generally necessary to connect multiple guardrails to form a circle. The current guardrails are generally rigid structures that cannot be adjusted, which makes it easy to fall when the guardrails are fixed on the slope. Therefore, how to realize a road construction guardrail that can adjust the guardrail angle according to the slope angle has become an urgent problem to be solved. Utility Model Content

[0003] Based on this, it is necessary to propose a road construction guardrail that can adjust the angle of the guardrail according to the slope angle to address the above problems.

[0004] The present application provides a guardrail for road construction, which is used to enclose a construction range on a ramp, and includes a guardrail body and a guardrail base;

[0005] A first connecting opening is provided below the guardrail body, and a second connecting opening is provided on the guardrail base. When the guardrail base is arranged below the guardrail body, the first connecting opening and the second connecting opening overlap and are inserted with a rotating shaft for fixation, thereby movably setting the guardrail base below the guardrail body, so as to achieve the effect that the guardrail base can adjust the inclination angle according to the slope of the ground.

[0006] Furthermore, a connecting shaft is connected between the guardrail base and the guardrail body;

[0007] One end of the connecting shaft is fixed to the guardrail base through a rotating shaft, and the other end of the connecting shaft is fixed to the side wall of the guardrail body through a rotating shaft. When the guardrail base needs to be tilted to match the ground slope, the connecting shaft can limit and fix the relative angle between the guardrail base and the guardrail body.

[0008] Furthermore, the connecting shaft is a telescopic screw rod, the fixed end of the telescopic screw rod is fixed to the guardrail base through a rotating shaft, and the extended end of the telescopic screw rod is fixed to the side wall of the guardrail body through a rotating shaft. When the guardrail base needs to be tilted to match the slope of the ground, the telescopic screw rod can be locked after extending the extended end of the corresponding length according to the inclination angle, thereby limiting and fixing the relative angle between the guardrail base and the guardrail body.

[0009] Furthermore, a height adjustment module is provided on the side wall of the guardrail body;

[0010] A height-adjustable connecting piece is provided in the height adjustment module, and the other end of the connecting shaft can be movably fixed to the connecting piece through a rotating shaft, so that the other end of the connecting shaft can move up and down on the side wall of the guardrail body, so that the connecting shaft can limit and fix the relative angle between the guardrail base and the guardrail body.

[0011] Further, the height adjustment module includes a rotating disk;

[0012] The connecting member is fixed to the rotating disk via a rotating shaft. When the rotating disk rotates, the other end of the connecting shaft can be driven to move up and down on the side wall of the guardrail body, thereby achieving the effect of the connecting shaft limiting and fixing the relative angle between the guardrail base and the guardrail body.

[0013] Furthermore, the rotating disk is divided into several identification areas, and an identification frame is provided in the identification area. The identification frame is used to identify the relative angle between the guardrail base and the guardrail body. An indicator arrow is provided on one side of the rotating disk. The indicator arrow is used to point to the identification frame when the rotating disk is rotated to a set position, thereby indicating the relative angle between the guardrail base and the guardrail body.

[0014] Furthermore, a locking opening is provided on the identification area;

[0015] A fixed opening is provided on the side wall of the guardrail body. When the rotating disk rotates to a set position, the fixed opening and the locking opening overlap with each other and are locked by an external plug, thereby preventing the rotating disk from continuing to rotate.

[0016] Furthermore, a water tank is provided on the guardrail base;

[0017] The water storage tank is arranged above the guardrail base, and a water inlet is provided on the side wall of the water storage tank, so as to increase the deadweight of the guardrail base after water is stored, thereby achieving the effect of improving the stability of the guardrail base.

[0018] The utility model adopts the above structure, by setting a first connecting opening below the guardrail body and a second connecting opening above the guardrail base, and fixing the guardrail base through a rotating shaft when the first connecting opening and the second connecting opening coincide with each other, thereby movably setting the guardrail base below the guardrail body, so as to achieve the effect that the guardrail base can adjust the inclination angle according to the slope of the ground, solves the problem in the prior art that the guardrail is generally a rigid structure that cannot be adjusted, which makes it easy to tip over when the guardrail is fixed on a slope, and improves the flexibility of the guardrail setting.

[0028] A first connecting opening is provided below the guardrail body 10, and a second connecting opening is provided on the guardrail base 20. When the guardrail base 20 is set below the guardrail body 10, the first connecting opening and the second connecting opening overlap and are inserted into a rotating shaft for fixation, so that the guardrail base 20 is movably set below the guardrail body 10, so as to achieve the effect that the guardrail base 20 can adjust the inclination angle according to the slope of the ground.

[0029] As described in the above embodiment, the guardrail is composed of a guardrail body 10 and a guardrail base 20. A first connecting opening is provided below the guardrail body 10, and a second connecting opening is provided on the guardrail base 20. Therefore, when the guardrail base 20 is set below the guardrail body 10, the first connecting opening and the second connecting opening overlap and are inserted into a rotating shaft for fixation, thereby achieving the effect of movably setting the guardrail base 20 below the guardrail body 10, so that the guardrail base 20 can adjust the inclination angle according to the slope of the ground.

[0030] Through the above structure, this embodiment sets the first connecting opening below the guardrail body and the second connecting opening above the guardrail base, and fixes the guardrail base through a rotating shaft when the first connecting opening and the second connecting opening coincide with each other, thereby achieving the effect that the guardrail base can adjust the inclination angle according to the ground slope, solving the problem in the prior art that the guardrail is generally a rigid structure that cannot be adjusted, resulting in the guardrail being easy to tip over when fixed on a slope, and improving the flexibility of the guardrail setting.

[0031] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , In one embodiment, a connecting shaft 30 is connected between the guardrail base 10 and the guardrail body 20;

[0032] One end of the connecting shaft 30 is fixed to the guardrail base 10 through a rotating shaft, and the other end of the connecting shaft 30 is fixed to the side wall of the guardrail body 20 through a rotating shaft. When the guardrail base 10 needs to be tilted to match the ground slope, the connecting shaft 30 can limit and fix the relative angle between the guardrail base 10 and the guardrail body 20.

[0033] As described in the above embodiment, a connecting shaft 30 is connected between the guardrail base 10 and the guardrail body 20. It can be understood that the connecting shaft 30 is used to limit and fix the relative angle between the guardrail base 10 and the guardrail body 20. Therefore, in this embodiment, the connecting shaft 30 is arranged on the side walls on both sides of the guardrail body 20, so that one end of the connecting shaft 30 is fixed to the guardrail base 10 through a rotating shaft, and the other end of the connecting shaft 30 is fixed to the side wall of the guardrail body 20 through a rotating shaft. When the guardrail base 10 needs to be tilted to match the slope of the ground, the connecting shaft 30 can limit and fix the relative angle between the guardrail base 10 and the guardrail body 20.

[0034] refer to Figure 2In one embodiment, the connecting shaft 30 is a telescopic screw rod, the fixed end of the telescopic screw rod is fixed to the guardrail base 10 through a rotating shaft, and the extended end of the telescopic screw rod is fixed to the side wall of the guardrail body 20 through a rotating shaft. When the guardrail base 10 needs to be tilted to match the slope of the ground, the telescopic screw rod can be locked after extending the extended end of the corresponding length according to the inclination angle, thereby limiting and fixing the relative angle between the guardrail base 10 and the guardrail body 20.

[0035] As described in the above embodiment, the connecting shaft 30 is a telescopic screw rod. It can be understood that the fixed end of the telescopic screw rod is fixed to the guardrail base 10 through a rotating shaft, and the extended end of the telescopic screw rod is fixed to the side wall of the guardrail body 20 through a rotating shaft. When the guardrail base 10 needs to be tilted to match the slope of the ground, the telescopic screw rod can be locked after extending the extended end of the corresponding length according to the inclination angle, thereby limiting and fixing the relative angle between the guardrail base 10 and the guardrail body 20, thereby achieving the effect of locking the relative angle between the guardrail base 10 and the guardrail body 20.

[0036] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 , In one embodiment, a height adjustment module 40 is provided on the side wall of the guardrail body 20;

[0037] A height-adjustable connecting piece 41 is provided in the height adjustment module 40, and the other end of the connecting shaft 30 can be movably fixed on the connecting piece 41 through a rotating shaft, so that the other end of the connecting shaft 30 can move up and down on the side wall of the guardrail body 20, so that the connecting shaft 30 can limit and fix the relative angle between the guardrail base 10 and the guardrail body 20.

[0038] As described in the above embodiment, a height-adjustable connecting member 41 is provided in the height adjustment module 40, and the other end of the connecting shaft 30 can be movably fixed on the connecting member 41 through a rotating shaft. Therefore, when the connecting member 41 moves up and down on the side wall of the guardrail body 20, the other end of the connecting shaft 30 can be driven to move up and down on the side wall of the guardrail body 20, so that the connecting shaft 30 can move in accordance with the relative angle between the guardrail base 10 and the guardrail body 20, and after the connecting shaft 30 locks its extended end, the relative angle between the guardrail base 10 and the guardrail body 20 is limited and fixed.

[0039] refer to Figure 4In one embodiment, the height adjustment module 40 includes a rotating disk 42; the connecting member 41 is fixed to the rotating disk 42 through a rotating shaft. When the rotating disk 42 rotates, the other end of the connecting shaft 30 can be driven to move up and down on the side wall of the guardrail body 20, thereby achieving the effect of limiting and fixing the relative angle between the guardrail base 10 and the guardrail body 20 by the connecting shaft 30.

[0040] As described in the above embodiment, the height adjustment module 40 includes a rotating disk 42. It can be understood that the connecting member 41 is fixed to the rotating disk 42 through a rotating shaft. Therefore, when the other end of the connecting shaft 30 is fixed to the connecting member 41, the rotating disk 42 can rotate to adjust the height of the connecting member 41. Therefore, the other end of the connecting shaft 30 can also follow the connecting member 41 for height adjustment. At the same time, when the rotating disk 42 is locked and no longer rotated, the connecting shaft 30 can achieve the effect of limiting and fixing the relative angle between the guardrail base 10 and the guardrail body 20.

[0041] refer to Figure 4 In one embodiment, a rotating disk 42 is divided into a plurality of identification areas 43, and an identification frame 44 is provided in the identification area 43. The identification frame 44 is used to identify the relative angle between the guardrail base 10 and the guardrail body 20. An indication arrow 45 is provided on one side of the rotating disk 42. The indication arrow 45 is used to point to the identification frame when the rotating disk is rotated to a set position, thereby indicating the relative angle between the guardrail base and the guardrail body.

[0042] As described in the above embodiment, a plurality of identification areas 43 are divided on the rotating disk 42, and an identification frame 44 is provided in the identification area 43. The identification frame 44 is used to identify the relative angle between the guardrail base 10 and the guardrail body 20. It can be understood that, since in this embodiment, the length of the connecting shaft 30 is fixed, when the rotating disk 42 is locked at a specific angle, the user can identify the relative angle between the current guardrail base 10 and the guardrail body 20 through the identification frame 44 pointed to by the indicating arrow 45.

[0043] refer to Figure 4 , In one embodiment, a locking opening 46 is provided on the identification area 43;

[0044] A fixed opening is provided on the side wall of the guardrail body 20. When the rotating disk 42 rotates to a set position, the fixed opening and the locking opening 46 overlap with each other and are locked by an external plug, thereby preventing the rotating disk 42 from continuing to rotate.

[0045] As described in the above embodiment, a fixed opening is provided on the side wall of the guardrail body 20. When the rotating disk 42 rotates to a set position and needs to be locked, the fixed opening and the locking opening 46 overlap with each other and are locked by external plugs, thereby achieving a locking effect 47 of the rotating disk 42.

[0046] refer to Figure 2 and Figure 3 In one embodiment, a water storage tank 11 is also provided on the guardrail base 10;

[0047] The water storage tank 11 is arranged above the guardrail base 10 , and a water inlet 12 is arranged on the side wall of the water storage tank 11 , so as to increase the deadweight of the guardrail base 10 after water is stored, thereby achieving the effect of improving the stability of the guardrail base 10 .

[0048] As described in the above embodiment, a water tank 11 is further provided above the guardrail base 10. The water tank 11 is used to increase the deadweight of the guardrail base 10 by storing water through a water inlet 12 provided on the side wall, thereby achieving the effect of improving the stability of the guardrail base 10.

[0049] From the above embodiments, it can be known that the greatest beneficial effect of the present invention is that by setting a first connecting opening below the guardrail body and a second connecting opening above the guardrail base, and fixing the guardrail base through a rotating shaft when the first connecting opening and the second connecting opening coincide with each other, the guardrail base is movably set below the guardrail body, so that the guardrail base can adjust the inclination angle according to the ground slope, which solves the problem in the prior art that the guardrail is generally a rigid structure that cannot be adjusted, resulting in the guardrail being easy to tip over when fixed on a slope, thereby improving the flexibility of the guardrail setting.

[0050] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
