[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figures 1-13 As shown, the construction enclosure of this utility model includes a main board 100, a top plate 101 fixed to the top of the main board 100, a bottom plate 102 fixed to the bottom of the main board 100, and a slidable extension plate 200 on the side of the main board 100; a guide post 201 is provided at the top of the extension plate 200, and a guide groove 103 is provided on the top plate 101 to slide with the guide post 201; a pulley 202 is provided at the bottom of the extension plate 200, and a sliding groove 104 is provided on the bottom plate 102 to cooperate with the pulley 202.

[0018] The main board 100 is a vertically arranged cuboid plate. The top plate 101 and the bottom plate 102 are also cuboid plates. The top plate 101 and the bottom plate 102 are respectively vertically fixed to the top and bottom of the main board 100. The fixing method can be a fixing method commonly used in this technical field, such as adhesive fixing, bolt connection, integral molding, etc., and no specific limitation is made here.

[0019] When in use, the base plate 102 abuts against the construction ground to support the fence; the width A of the base plate 102 is greater than the width B of the main plate 100, which can increase the contact area between the fence and the construction ground and improve the stability and reliability of the fence support.

[0020] In addition, multiple anchor bolts can be connected to the base plate 102 according to usage requirements. The anchor bolts are inserted into the construction ground to enhance the firmness, so that the fence can be stably and effectively supported on the construction ground, thereby effectively preventing pedestrians from knocking down or kicking the fence.

[0021] The extension plate 200 is a vertically arranged cuboid plate. The extension plate 200 is parallel to the main plate 100, and the vertical height of the extension plate 200 is less than the vertical height of the main plate 100.

[0022] The guide post 201 is cylindrical and is arranged along the sliding direction of the extension plate 200.

[0023] The guide post 201 can be fixed to the top of the extension plate 200 by multiple connecting rods 203. The connecting rods 203 and the guide post 201 are perpendicular to each other. The connecting rods 203 are fixed vertically to the top of the extension plate 200, and the top of the connecting rods 203 is fixed to the bottom of the guide post 201. The fixing method can be a common fixing method in this technical field, such as adhesive fixing, bolt connection, integral molding, etc., and no specific limitation is made here.

[0024] The guide groove 103 has a circular cross-sectional shape and an avoidance opening 105 at the bottom. The avoidance opening 105 at the bottom of the guide groove 103 extends along the length of the guide groove 103.

[0025] The diameter of the guide post 201 is smaller than the inner diameter of the guide groove 103. The guide post 201 is slidably fitted within the guide groove 103. The connecting rod 203 is loosely fitted within the clearance opening 105 at the bottom of the guide groove 103, allowing the connecting rod 203 to pass. Through the sliding fit between the guide post 201 and the guide groove 103, the extension plate 200 can slide, and the sliding of the extension plate 200 can be guided and limited. The sliding of the extension plate 200 allows it to extend and / or retract, enabling the extension and retraction of the fence to adjust its length, improving its flexibility and allowing it to meet various fence length requirements.

[0026] Both ends of the guide groove 103 are open or at least one end is open. The guide post 201 can be easily inserted into the guide groove 103 through the end opening of the guide groove 103 to realize the installation of the extension plate 200. Alternatively, the guide post 301 can slide out from the end opening of the guide groove 103 to realize the sliding of the extension plate 200.

[0027] The top surface of the base plate 102 is provided with a recessed groove 104, which is parallel to the guide groove 103. The bottom of the extension plate 200 is connected to at least one rotatable pulley 202, which can roll along the groove 104, thereby guiding the sliding of the extension plate 200 and making the extension plate 200 slide more smoothly.

[0028] The pulley 202 can be rotatably connected to the bottom of the extension plate 200 in a manner common in the art, without any specific limitations.

[0029] Both ends of the slide 104 are open, or at least one end is open, so that the pulley 202 can enter and exit the slide 104 through the opening of the slide 104.

[0030] The extension plate 200 is provided with a locking elongated hole 204, which is a through hole and extends along the sliding direction of the extension plate 200. The main plate 100 has at least one locking groove (not shown in the figure) on the side corresponding to the extension plate 200. The locking groove can be a threaded groove recessed on the side of the main plate 100. The locking groove and the locking elongated hole 204 are at the same height and correspond to each other. After the extension plate 200 slides to the target position, a locking bolt 205 can be connected in the locking elongated hole 204 and the locking groove to lock and limit the extension plate 200, preventing it from sliding further and maintaining it in the target position. In addition, when the fence is not needed, the extension plate 200 can be slid back (the extension plate 200 and the main plate 100 overlap), and then the locking bolt 205 is connected in the locking elongated hole 204 and the locking groove to lock and limit the extension plate 200, so that the extension plate 200 can no longer slide and remains in the retracted state, reducing the overall length of the fence, reducing the space occupied by the fence, and facilitating the handling and storage of the fence.

[0031] The sides of the main board 100 and the extension board 200 are equipped with reflective film (not shown in the figure), which can serve as a reflective warning to warn unauthorized personnel not to enter the construction area of ​​the enclosure.

[0032] The top of the top plate 101 is equipped with multiple warning lights (not shown in the figure). When the warning lights are turned on at night, they can serve as a warning to unauthorized personnel not to enter the construction area of ​​the enclosure.

[0033] The side of the extension plate 200 is provided with a vertical groove 206. The vertical groove 206 is provided with a limiting member and a supporting member. The supporting member is used to support the extension plate 200, and the limiting member is used to limit the supporting member.

[0034] The support is a symmetrical integral component, which includes two parallel support rods 301. One end of the two support rods 301 is connected by a U-shaped abutment rod 302, and the two ends of the U-shaped abutment rod 302 are respectively connected to the two support rods 301.

[0035] The other ends of the two support rods 301 are respectively provided with connecting rods 303. The connecting rods 303 are perpendicular to the support rods 301, and the two connecting rods 303 are rotatably connected to the groove wall 209 of the vertical groove 206.

[0036] The vertical groove 206 is cuboid in shape and is recessed into the side of the extension plate 200. The vertical groove 206 is located below the locking elongated hole 204 and extends vertically downward to the bottom of the extension plate 200, with an opening at the bottom.

[0037] The vertical groove 206 includes two symmetrical and corresponding groove walls 209, which are arranged vertically. Each groove wall 209 has a corresponding recessed rotating groove 208. The two connecting rods 303 are rotatably inserted into the two rotating grooves 208, thereby enabling the overall rotation of the support member and allowing the support member to be rotatably connected within the vertical groove 206.

[0038] The position of the rotating groove 208 on the groove wall 209 is not specifically limited, as long as the connecting rod 303 can be rotatably connected within the rotating groove 208.

[0039] When in use, the fence is moved to the construction site, and the base plate 102 rests against the construction ground to support the fence. After the extension plate 200 is slid to the target position, the support member is rotated and opened so that the support member also rests against the construction ground, and the support member can support the extension plate 200. This can increase the overall support stability of the fence and reduce the risk of pedestrians accidentally knocking over or kicking the fence.

[0040] Since the abutment rod 302 can abut against the construction ground when the support rod 301 is rotated to an inclined or vertical state, the angle between the abutment rod 302 and the support rod 301 is designed to be an obtuse angle or a right angle, which can increase the contact length and contact area of ​​the abutment rod 302 on the construction ground and improve the support stability of the support member on the extension plate 200.

[0041] like Figure 9As shown, a closed connecting ring 304 can be welded and fixed inside the abutment rod 302. According to the usage requirements, anchor nails can be connected inside the connecting ring 304. The anchor nails are inserted into the construction ground and press against the connecting ring 304, thereby enhancing the stability of the abutment rod 302 against the construction ground and providing a stable and effective support for the extension plate 200.

[0042] The anchoring pin can be any anchoring pin commonly used in this technical field, such as a ground nail, and no specific limitation is made here.

[0043] An anti-slip pad (not shown in the figure) can be fitted onto the abutment rod 302 to enhance the friction between the abutment rod 302 and the construction ground, so that the abutment rod 302 can be stably and effectively supported on the construction ground.

[0044] When the support is not needed, the support can be rotated and retracted into the vertical groove 206. For example... Figure 6 , Figure 8 , Figure 12 , Figure 13 As shown, the vertical groove 206 also has a recessed fitting groove 207. When the support rotates and retracts into the vertical groove 206, the abutment rod 302 can fit perfectly into the fitting groove 207. Since the angle between the abutment rod 302 and the support rod 301 is a right angle or an obtuse angle, the abutment rod 302 and the support rod 301 are not in the same plane, and the abutment rod 302 is raised. By setting the recessed fitting groove 207, the abutment rod 302 can be fitted into the fitting groove 207, which allows the support to be stably and effectively retracted into the vertical groove 206. This prevents the support from protruding from the side of the extension plate 200 and prevents the support from obstructing the sliding of the extension plate 200.

[0045] The limiting component includes two arc-shaped limiting plates 401, which are symmetrically arranged on the two groove walls 209 of the vertical groove 206.

[0046] The arc-shaped limiting plate 401 is arc-shaped, and one arc-shaped edge of the arc-shaped limiting plate 401 is fixed to the groove wall 209 of the vertical groove 206. The fixing method can be a common fixing method in this technical field, and no specific limitation is made here. For example, an arc-shaped fixing plate (not shown in the figure) is provided on the edge of one arc-shaped edge of the arc-shaped limiting plate 401. The arc-shaped fixing plate can be integrally formed with the arc-shaped limiting plate 401. The arc-shaped fixing plate is an arc-shaped flat plate, and the plane where the arc-shaped fixing plate is located is parallel to the radial direction of the arc-shaped limiting plate 401. The arc-shaped fixing plate is attached to the groove wall 209 of the vertical groove 206 and is connected to the groove wall 209 by bolts, so that the arc-shaped limiting plate 401 can be fixedly connected to the groove wall 209 of the vertical groove 206.

[0047] A first limiting groove 402 is provided on another arc-shaped edge of the arc-shaped limiting plate 401, and the first limiting groove 402 is located near the bottom of the arc-shaped limiting plate 401. When the support member rotates to the point where the contact rod 302 contacts the construction ground, the support rod 302 can cooperate in the first limiting groove 402, thereby limiting the support member and keeping it in contact with the construction ground, that is, keeping the support member in a supported state.

[0048] The top of the arc-shaped limiting plate 401 is also provided with a second limiting groove 403. When the support member rotates back into the vertical groove 206, the support rod 301 can cooperate in the second limiting groove 403, thereby limiting the support member and keeping the support member in the retracted state.

[0049] Preferred, such as Figure 11 As shown, the arc-shaped limiting plate 401 is installed on the groove wall 209 of the vertical groove 206. The center of the arc-shaped limiting plate 401 can coincide with the center of the rotating groove 208 on the groove wall 209, and the central angle of the arc-shaped limiting plate 401 can be greater than or equal to 180°. The second limiting groove 403 can be set at the top of the arc-shaped limiting plate 401. The line connecting the midpoint of the second limiting groove 403 and the center of the arc-shaped limiting plate 401 is vertically arranged. When the support rod 301 is engaged in the second limiting groove 403, the support rod 301 can be set vertically or nearly vertically, so that the support can be stably and effectively retracted into the vertical groove 206. The first limiting groove 402 is located near the bottom of the arc-shaped limiting plate 401. The specific position of the first limiting groove 402 needs to ensure that when the support rod 301 is engaged in the first limiting groove 402, the abutting rod 302 can abut against the construction ground. Alternatively, there can be multiple first limiting grooves 402. The support rod 301 can be engaged in one of the first limiting grooves 402 according to the actual situation of the construction site, so that the abutting rod 302 abuts against the construction ground.

[0050] The support component is a single piece, and it can be made by bending a single iron rod.

[0051] In this application, when the support member needs to be rotated, the two support rods 301 can be squeezed together to bring them closer, thereby disengaging the two support rods 31 that are limited to the first limiting groove 402 or the second limiting groove 403, releasing the limitation on the support member, and thus allowing the support member to rotate. When the support rods 301 rotate to the position of the second limiting groove 403 or the first limiting groove 402, the two support rods 301 are released, allowing the support rods 301 to move and engage with the second limiting groove 403 or the first limiting groove 402.

[0052] Two arc-shaped limiting plates 401 are symmetrically arranged. The first limiting grooves 402 on the two arc-shaped limiting plates 401 are at the same height, and the second limiting grooves 403 on the two arc-shaped limiting plates 401 are at the same height. The distance between the two first limiting grooves 402 is equal to the distance between the two second limiting grooves 403.

[0053] When the support is not under stress, the distance between the two support rods 301 is greater than or equal to the distance between the two corresponding first limiting grooves 402 on the two arc-shaped limiting plates 401, so that when the two support rods 301 are released, the two support rods 301 can move and cooperate in the first limiting groove 402 or the second limiting groove 403.

[0054] In one embodiment of this application, as Figure 12 and Figure 13 As shown, there can be two vertical grooves 206. The two vertical grooves 206 are symmetrically arranged on the two sides of the extension plate 200. The corresponding number of support members and limiting members is also two. The two support members are symmetrically arranged on the two sides of the extension plate 200, which can provide symmetrical support for the two sides of the extension plate 200, so as to achieve stable and effective support for the extension plate 200. This allows the fence to be firmly and effectively supported on the construction ground, thereby effectively preventing pedestrians from knocking down or kicking over the fence.

[0055] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
