Description

Technical Field

[0001] The utility model relates to the field of construction enclosures, in particular to a road construction enclosure. Background Art

[0002] With the rapid development of urbanization, roads, bridges, water supply and drainage, electricity, telecommunications, gas facilities, landscaping, industrial buildings and residential construction sites are spread all over the country. In order to maintain road quality, beautify the construction environment and ensure construction safety, when repairing roads, fences need to be placed at the construction site to separate the construction area from the personnel activity area and pedestrian area.

[0003] Existing road construction fences, if they want to implement all-round shielding of the construction site, mostly use a fence method composed of multiple baffles to ensure that pedestrians at different positions on the road can see the fence structure. However, during the long-term operation of the baffles used to implement the fence, if one of the baffles is offset or tilted to a certain extent under the action of external force, since the multiple baffles are located close to each other, it is easy to affect the baffles at other positions, causing the baffles at other positions to also offset or tilt, thereby affecting the stability of the entire fence structure, making it inconvenient for the normal progress of road construction. Utility Model Content

[0004] In response to the above problems, the present application provides a road construction fence.

[0005] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a road construction fence, comprising a plurality of baffles connected by hinges and a plurality of bases arranged under the baffles, wherein the plurality of baffles form a hexagonal structure, and the bases can move synchronously with the baffles.

[0006] Both ends of the base are provided with accommodating areas, and the bottom walls of the accommodating areas at both ends of the same base are respectively connected with a first limit arm and a second limit arm through a rotating shaft, and the surface of the first limit arm is embedded with a positioning screw sleeve, and a supporting structure is arranged on the positioning screw sleeve. When the multiple baffles and the base are distributed in a hexagonal shape, the ends of the first limit arm and the second limit arm of the connecting ends of two adjacent baffles are slidably connected, and the supporting structure longitudinally penetrates the first limit arm and the second limit arm, and the outer surface of the supporting structure is provided with a limiting structure that can limit the displacement of the second limit arm.

[0007] Furthermore, the supporting structure includes a linkage screw rod adapted to the positioning screw sleeve, the bottom end of the linkage screw rod is fixedly connected to a pressure plate that can contact the ground, and the end of the second limiting arm is provided with a receiving notch for accommodating the linkage screw rod. When the ends of the first limiting arm and the second limiting arm are slidably docked, the linkage screw rod is inserted into the inner side of the receiving notch.

[0008] Furthermore, the limiting structure includes a positioning sleeve fixed to the outer surface of the linkage screw. When the ends of the first limiting arm and the second limiting arm are connected, the positioning sleeve is located below the second limiting arm. The lower surface of the second limiting arm is provided with alignment holes symmetrically distributed on both sides of the accommodating notch.

[0009] The outer surface of the positioning sleeve protrudes outward to form symmetrically distributed extension protrusions, and the upper surfaces of the extension protrusions are connected to limiting balls that are compatible with the alignment holes through pressure springs. When the end of the second limiting arm slides over the limiting ball to below the end of the first limiting arm, the limiting ball drops, squeezing the pressure spring to contract until the alignment hole corresponds to the limiting ball.

[0010] Furthermore, the upper surfaces of the extending protrusions are fixedly connected with guide rods, the guide rods are located directly below the limiting balls, and the guide rods are coaxially distributed with the pressure springs.

[0011] Furthermore, a plurality of cross bars are fixed on the surface of the baffle from top to bottom, and handles are embedded in positions on the surface of the baffle above the cross bars.

[0012] Furthermore, universal wheels are symmetrically installed on the bottom of the base.

[0013] In summary, the technical effects and advantages of the utility model are:

[0014] In the utility model, when multiple baffles and bases are distributed in a hexagonal shape to form an enclosure structure, the ends of the first limiting arm and the second limiting arm at the connecting ends of two adjacent baffles are connected through a supporting structure, which can maintain the stability of the first limiting arm, the second limiting arm and their mounting ends, so as to achieve the purpose of maintaining the stability of the base, avoid the base itself from tipping over, and ensure the stability of the baffle and the base in the enclosure state. The limiting structure on the supporting structure can tightly position the first limiting arm and the second limiting arm, avoid the shaking and offset of the baffle and the base affecting the stability of the connection between the first limiting arm and the second limiting arm, and maintain the stability of the two in a long-term connection state.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: Reference Figure 1 , Figure 2 A road construction fence shown in the figure includes a plurality of baffles 1 connected by hinges and a plurality of bases 2 arranged under the baffles 1. The plurality of baffles 1 form a hexagonal structure. The base 2 can move synchronously with the baffles 1 to reach a designated position to implement the fence operation. Construction workers can carry out road construction in the fence space, which has a warning effect on pedestrians and vehicles and ensures the safety of construction workers.

[0024] Both ends of the base 2 are provided with a receiving area 21, and the bottom walls of the receiving areas 21 provided at both ends of the same base 2 are respectively connected with the first limiting arm 3 and the second limiting arm 4 through a rotating shaft, and the surface of the first limiting arm 3 is embedded with a positioning screw sleeve 31, and a supporting structure is arranged on the positioning screw sleeve 31. When multiple baffles 1 and bases 2 are distributed in a hexagonal shape, the ends of the first limiting arm 3 and the second limiting arm 4 at the connecting ends of two adjacent baffles 1 can be controlled to slide and dock. After the two are slid and docked, the supporting structure longitudinally penetrates the first limiting arm 3 and the second limiting arm 4 to maintain the stability of the first limiting arm 3, the second limiting arm 4 and their installation ends, avoid the base 2 itself from tipping over, and ensure the stability of the baffle 1 and the base 2 in the enclosure state.

[0025] The outer surface of the supporting structure is provided with a limiting structure which can limit the displacement of the second limiting arm 4, thereby preventing the second limiting arm 4 from detaching from the supporting structure and the first limiting arm 3. The first limiting arm 3 and the second limiting arm 4 can be tightly positioned to prevent the shaking and displacement of the baffle 1 and the base 2 from affecting the stability of the connection between the first limiting arm 3 and the second limiting arm 4, thereby maintaining the stability of the two when connected for a long time.

[0026] like Figure 4 , Figure 5 As shown, the support structure includes a linkage screw 5 matched with the alignment screw sleeve 31, the bottom end of the linkage screw 5 is fixedly connected with a pressure plate 6 that can contact the ground, and the end of the second limit arm 4 is provided with a receiving notch 41 for accommodating the linkage screw 5. When the ends of the first limit arm 3 and the second limit arm 4 are slidably docked, the linkage screw 5 is inserted into the inner side of the receiving notch 41 to achieve the purpose of simultaneously connecting the first limit arm 3 and the second limit arm 4. Subsequently, the linkage screw 5 can be rotated, and the pressure plate 6 is pressed tightly against the ground to maintain the stability of the connecting ends of the two adjacent bases 2 and prevent the baffle 1 from tipping over.

[0027] like Figure 3 , Figure 4 As shown, the limiting structure includes a positioning sleeve 51 fixed to the outer surface of the linkage screw 5. When the ends of the first limiting arm 3 and the second limiting arm 4 are connected, the positioning sleeve 51 is located below the second limiting arm 4. The lower surface of the second limiting arm 4 is provided with alignment holes 42 symmetrically distributed on both sides of the accommodating notch 41.

[0028] The outer surface of the positioning sleeve 51 protrudes outward to form symmetrically distributed extension protrusions 52, and the upper surfaces of the extension protrusions 52 are connected to the limiting balls 8 that match the alignment holes 42 through the pressure springs 7. When the first limiting arm 3 and the second limiting arm 4 are slidably docked, the end of the second limiting arm 4 passes over the limiting balls 8 and slides to the bottom of the end of the first limiting arm 3, and the limiting balls 8 descend, squeezing the pressure springs 7 to contract. When the alignment holes 42 correspond to the limiting balls 8, the pressure springs 7 are reset, driving the limiting balls 8 to be smoothly placed into the alignment holes 42.

[0029] By limiting the connection between the ball 8 and the alignment hole 42, the tightness of the connection between the second limiting arm 4, the first limiting arm 3 and the supporting structure can be maintained, and the second limiting arm 4 can be prevented from being separated from the first limiting arm 3. Therefore, the supporting structure composed of the linkage screw 5 and the pressure plate 6 can achieve the purpose of tightly positioning the first limiting arm 3 and the second limiting arm 4 through the limiting structure on its surface, and maintain the stability of the two in a long-term connection state.

[0030] The arrangement of the supporting structure and the limiting structure at the six points improves the stability of each baffle 1, avoids the shaking of one baffle 1 in the hexagonal enclosure structure and affects the entire enclosure structure, and effectively improves the overall stability of the enclosure structure.

[0031] like Figure 4 As shown, the upper surface of the extended protrusion 52 is fixedly connected with a guide rod 53, which is located directly below the limiting ball 8, and the guide rod 53 is coaxially distributed with the pressure spring 7. The purpose of adding the guide rod 53 is to prevent the limiting ball 8 from swinging excessively under the pressure of the second limiting arm 4, thereby preventing the limiting ball 8 from being able to be smoothly connected with the alignment hole 42, thereby improving the accuracy of the connection process between the limiting ball 8 and the alignment hole 42.

[0032] like Figure 2 As shown, a plurality of cross bars 11 are fixed on the surface of the baffle 1 from top to bottom. The cross bars 11 ensure the structural strength of the baffle 1 and facilitate the workers to observe the environment outside the baffle 1 during the construction process. A handle 12 is embedded on the surface of the baffle 1 above the cross bars 11. After the construction operation is completed, the baffle 1 and the base 2 below it can be moved by controlling the handle 12.

[0033] like Figure 2 As shown, universal wheels 22 are symmetrically installed at the bottom of the base 2. The purpose of adding the universal wheels 22 is to facilitate the control of the synchronous movement of the baffle 1 and the base 2, thereby improving the portability of the entire enclosure structure during movement.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
