DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION

(12) With reference to FIGS. 13, the fence 1 is shown on an embodiment of the present invention and each fence unit comprises two side posts 10, at least two cross bars 20 connected between the left and right side posts 10, and a plurality of vertical bars 30 connected between the cross bars 20 arranged up and down.

(13) Each side post 10 (as shown in FIG. 2) comprises a square side post tube 11 and a reinforcing post 12 defined inside the side post tube 11. The side post tube 11 is a hollow shape, and the tube wall 110 at the position where connecting to the cross bars 20 is configured with the connecting holes 111 to provide the end portion of the cross bar 20 to pass into the side post tube 11 through the connecting holes 111. The four sides of the reinforcing post 12 facing the side post tube 11 are respectively configured with three longitudinal boards 120 and a connecting board 121 extending coaxially with the side post tube 11 and arranged radially, wherein a gap with 90 degrees is defined between the adjacent three longitudinal boards 120 and the connecting board 121. The outside end of the connecting board 121 is connected with an abutting board 122, wherein the abutting board 122 and the connecting board 121 are in a vertical connection, and the lateral board edges 1200 of the three longitudinal boards 120 and the outside board surface of the abutting board 122 contact with the inner walls of the side post tube 11 (as shown in FIG. 4), thereby reinforcing the rigidity of the side post tube 11. The board edges of each longitudinal board 120 at the position facing the connecting holes on the each side post wall 110 of the side post tube 11 (excluding the connecting hole 111 located on the uppermost position of the side post tube 11) is configured with a notch 123 longer than the hole height of the connecting hole 111 and a gap 124 of the notch 123 faces the connecting hole 111. The bottom end of the reinforcing post 12 is configured with a cone part 125 exposed out of the bottom end of the side post tube 11, which can be hammered into the soils and fixed while installing the fence 1.

(14) When installing and assembling the fence 1, firstly the cone part 125 at the bottom end of the reinforcing post 12 is hammered into the soils, the side post tube 11 is further sleeved outside the reinforcing post 12 and configured in a manner of the notch 123 corresponding to the connecting hole 111, afterwards, the two ends of the cross bar 20 located below (defined as a lower cross bar 20a) are respectively passing into the notch 122 through the connecting hole 111 and the gap 123, and then, a fixing component 40 (such as a screw) is utilized to pass through the abutting board 122 and lower cross bar 20a from the outside of the side post tube 11 to fix and combine the reinforcing post 12 and the side post tube 11 to be a complete side post 10, and meanwhile fixing the lower cross bar 20a. Furthermore, another fixing component 41 is utilized to fix the cross bar 20 located above (defined as an upper cross bar 20b) with the side post tube 11 from the outside of the side post tube 11, thereby connecting the upper cross bar 20b, the lower cross bar 20a and the side post 10, as shown in FIGS. 3 and 4. The multiple fences 1 are in a linear arrangement combination as shown in FIGS. 5 and 6, and thus, the two longitudinal boards 120 at an interval of 180 degrees can be used to connect and assemble to become a linear arrangement fences 1. When the installation site of the fence 1 is a slope, the end of the cross bar 20 will bend inside the notch 122 according to the change of ground surface and the upper and lower angles of the cross bar 20 will be changed (as shown in FIG. 7) because the internal height of the notch 122 is higher than the height of the connecting hole 111, thereby enabling the installation of the fence 1 not to be affected by the surface condition of the ground.

(15) Further as shown in FIGS. 8 and 9, the structural views are related to the fences 1 arranged and installed at right angle. In the embodiment of the present invention, the three longitudinal boards 120 of the reinforcing post 12 are respectively adjacent and spaced at 90 degrees and respectively configured with a notch 123, and thus the two longitudinal boards 120 spaced at 90 degrees can be used for the connection of the lower cross bar 20a to enable the two fences 1 to be in a right-angle bending arrangement, as shown in FIGS. 8 and 9 and further, as shown in FIGS. 10 and 11. The three longitudinal boards 120 are respectively connected with a lower cross bar 20a to enable the fence 1 to be assembled in a T-shaped and the fence 1 are allowed to be assembled according to the demands.

(16) It can be seen from the foregoing description that the present invention has the following advantages and effects in application. 1. The reinforcing post 12 are provided with the three longitudinal boards 120 and an abutting board 122 and the lateral board edges 1200 of the longitudinal boards 120 and the outside board surface of the abutting board 122 contact with the internal wall of the side post tube 11, and the abutting board 122 is fixed with the side post tube 11 via the fixing components 40, thereby reinforcing the rigidity of the side post tube 11 to enable the structural strength of the side post tube 10 to be good. 2. The three longitudinal boards 120 of the reinforcing post 12 of the present invention are respectively spaced at 90 degrees, and the board edge 1200 of each longitudinal board 120 is respectively configured with a notch 123, and thus, the side post 10 can be used to connect the fences 1 in the linear, right-angle or T-shaped arrangement.

(17) In summary, the present invention meets the requirements of novelty, inventiveness and practical applicability, and therefore an application for patent is hereby filed according to the law. Your examination and approval will be highly appreciated.
