[0027] The structure and specifications of the support rod 100 are exactly the same on both the left and right sides. There is a crossbar 300 on the upper and lower right sides of the support rod 100, and the two sets of crossbars 300 are set in a mirror symmetrical manner.

[0028] On the opposite side of the two sets of crossbars 300, several sets of slots 320 are opened one after another from left to right. A vertical bar 400 is fitted between the two sets of slots 320 that are opposite each other. The support rod 100, the base assembly 200, the crossbars 300 and the vertical bar 400 are all provided with several sets of the same specifications.

[0029] The crossbar 300 and the sliding mounting block 310 are an integral structure. The specifications of the sliding mounting block 310 match the specifications of the sliding mounting groove 110. Each set of sliding mounting blocks 310 is fixed to the front of the support rod 100 by a set of bolts. The front of the sliding mounting block 310 has screw holes. The distance between the screw holes on the upper and lower sets of sliding mounting blocks 310 matches the height of the vertical rod 400. The support rod 100 has through holes at the top and bottom of the front. The distance between the two sets of through holes matches the distance between the two sets of screw holes. The two sets of sliding mounting blocks 310 on one side are fixed by two sets of bolts. Therefore, the two sets of crossbars 300 can be fixed by four sets of bolts.

[0030] The bottom of the connecting rod 220 is welded to the center of the top of the chassis 210. A rubber layer is glued to the bottom of the chassis 210. Four sets of ground nail holes 211 are equidistantly opened in the annular area away from the center of the top of the chassis 210. The bottom of the rubber layer is provided with anti-slip texture to increase the friction between the chassis and the ground. The ground nail holes 211 are fixed to the ground by ground nails to increase the connection stability between the base assembly 200 and the ground.

[0031] The outer side of the swivel rod 130 is threaded, and the inner side of the swivel hole 221 is provided with an internal thread groove that matches the thread specification. The radius length and height of the swivel rod 130 match the radius length and depth of the swivel hole 221.

[0032] The swivel rod 130 and the support rod 100 are an integral structure. The swivel rod 130 is a cylindrical structure, and the support rod 100 is a cuboid structure. A plug 120 is installed on the inner side of the support rod 100, and the shape of the plug 120 matches the shape of the sliding mounting groove 110.

[0033] The vertical bar 400 has a cylindrical structure, and its radius matches the radius of the slot 320. The height of the vertical bar 400 matches the distance between the two sets of horizontal bars 300.

[0034] Example 1: Please refer to Figures 1 to 4 In actual use, the support rod 100, base assembly 200, horizontal bar 300, and vertical bar 400 are all provided in several sets. Each set of support rod 100 is equipped with two plugs 120 at the top. The plugs 120 are made of rubber, and their shape matches the shape of the sliding mounting groove 110. A sliding mounting groove 110 is opened on each of the left and right sides of the support rod 100. The sliding mounting groove 110 has a U-shaped structure, and its top is connected to the top of the support rod 100. The gap between its bottom and the ground is 5cm. A screw rod 130 is provided at the bottom of the support rod 100. The base assembly 200 is located below the support rod 100. The seat assembly 200 includes a chassis 210 and a connecting rod 220. The bottom of the connecting rod 220 is welded to the center of the top of the chassis 210. The top of the connecting rod 220 is recessed downward to form a screw hole 221. Four sets of ground nail holes 211 are equidistantly opened in the annular area away from the center of the top of the chassis 210. Two sets of crossbars 300 are provided on the right side of the support rod 100. A sliding mounting block 310 is provided on both the left and right sides of the crossbar 300. The shape of the sliding mounting block 310 matches the shape of the sliding mounting groove 110. Several sets of slots 320 are opened from left to right on the opposite side of the two sets of crossbars 300. A vertical rod 400 is installed inside the upper and lower sets of slots 320.

[0035] During actual installation, first prepare two sets of base assemblies 200. Determine the distance between the two sets of support rods 100 based on the length of the crossbar 300. Then, determine the distance between the two sets of base assemblies 200 using the distance between the two sets of support rods 100. Install the base assemblies 200 on the ground using four sets of ground nails. After installing both sets of base assemblies 200, pick up one support rod 100 and insert the screw rod 130 at the bottom of the support rod 100 downwards into the screw hole 221 at the top of the left connecting rod 220. Then, rotate the support rod 100 so that it connects with the left base assembly 200. 0. Fix it. Following the steps above, pick up another support rod 100 and install it on the top of the right base assembly 200. It should be noted that both the support rod 100 and the connecting rod 220 are cuboid structures. After the support rod 100 is installed on the top of the connecting rod 220, the four sides of the support rod 100 are flush with the four sides of the connecting rod 220. The two sets of sides of the support rod 100 with sliding mounting grooves 110 are distributed on the left and right. Therefore, after the two sets of support rods 100 are installed, the sliding mounting grooves 110 on the right side of the left support rod 100 are opposite to the sliding mounting grooves 110 on the left side of the right support rod 100.

[0036] Pick up a horizontal bar 300 with the side of the horizontal bar 300 with the slot 320 facing upwards. Then, slide the sliding mounting blocks 310 on the left and right sides of the horizontal bar 300 downwards along the two sets of sliding mounting grooves 110 until the two sets of sliding mounting blocks 310 are at the bottom of the two sets of sliding mounting grooves 110. At this point, the horizontal bar 300 is installed below the two sets of support rods 100. Pick up several sets of vertical rods 400 in sequence and insert them into the slots 320 in sequence from left to right. Then, pick up another horizontal bar 300 with the side of the horizontal bar 300 with the slot 320 facing downwards, and insert the second set of horizontal bars 300 downwards in the same manner as above, so that the second set of horizontal bars 300 is located above the two sets of support rods 100, with the tops of the several sets of vertical rods 400 facing upwards. Insert the crossbars 300 into the slots 320 at the bottom of the second set of crossbars 300, so that the vertical bars 400 are fitted between the two sets of support bars 100 through the two sets of crossbars 300. After the crossbars 300 are installed, the sliding mounting block 310 is in a non-fixed state inside the sliding mounting groove 110. At this time, use bolts to fix the sliding mounting block 310, thereby fixing the two sets of crossbars 300. Finally, pick up the two sets of plugs 120 and insert the two sets of plugs 120 into the top of the two sets of sliding mounting grooves 110 respectively. Follow the above steps to install the support bars 100, base assembly 200, crossbars 300 and vertical bars 400 in sequence, and finally complete the overall installation of the building fence. Therefore, the final effect is to greatly improve the ease of disassembly and assembly of the building fence, thereby significantly improving the flexibility of use of the building fence.

[0037] Example 2: Please refer to Figure 3 When installing the base component 200 to the ground, the looseness of the ground soil must be considered first. If the ground soil is loose, a cement base can be pre-embedded under the ground to increase the stability of the base component 200. The base is also fixed by ground nails. The bottom of the chassis 210 is glued with a rubber layer with anti-slip texture. The rubber layer increases the friction between the chassis 210 and the ground, thereby increasing the friction between the base component 200 and the ground. Therefore, the final effect is that the ground nails are fixed to the ground through the nail holes 211, and the rubber layer increases the friction between the chassis 210 and the ground, which greatly increases the stability of the base component 200 installed on the ground, thus ensuring the overall stability of the building fence.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
