Description

Combined structure of fence

The invention relates to a combined fence structure, especially a fence structure formed by interweaving metal mesh wires to form a metal mesh and supporting pipes.

According to the conventional erection of the fence, generally the vertical pipe fittings are first fixed to the ground, and then the horizontal pipe fittings are combined and fixed between the two vertical pipe fittings to be supported by the vertical and horizontal pipe fittings The structure is used as a frame body, and the metal mesh is fixed in the frame body by welding, binding or clamping to complete the construction of the fence.

The common metal mesh generally forms a sheet metal mesh by interweaving a plurality of metal mesh wires, so that the sheet metal mesh can be wound up to facilitate storage and transportation. In addition, when the metal mesh is to be assembled into the frame of the fence, the two ends of the metal mesh are usually directly fixed on the hollow round pipe of the fence frame by binding or welding, however, fixing the metal mesh by binding has complicated procedures 1. The lack of labor and time. In addition, if the metal mesh is fixed by welding, the metal mesh needs to be cut and disassembled before it can be used repeatedly, lacking flexibility in assembly and use. In addition, when the metal mesh is used for winding, transportation, or assembly, the two ends of the metal mesh are sharp, so it is easy to cause stab wounds to the handling or assembly personnel during the operation process, so there is a lack of improvement.

In order to solve the above deficiencies, the Republic of China Announcement No. M448539 patent discloses a "diamond network structure", which is formed by winding the ends of each unit of a number of units into a diamond network in a closed manner. 1. There is no sharp-angled winding part, and a hollow perforation is formed inside the winding, so that after the outer cable group passes through several perforations of the winding part, the outer cable is fixed on the fence bracket and the diamond-shaped net is erected at the same time. However, although the uncovered technology can achieve the effect of diamond-shaped mesh edge-closing and improve the safety of operation, when the outer cable is broken, the diamond-shaped mesh monomer will hang down due to the loss of support, deforming the diamond-shaped mesh, and when it is to be replaced, It is also necessary to remove and re-fix the entire set of rhombic meshes, so there is clearly a lack of improvement.

In view of the sharp structure at the ends of the conventional metal mesh, it is easy to cause injuries to personnel during the operation, so there is still a need for improvement.

Therefore, the purpose of the present invention is to form a spiral portion at the end of the metal mesh to prevent the sharp structure at the end of the metal mesh from causing injury to the operator.

Another object of the present invention is to form a gap with an abutment portion in the hollow circular tube, so that the metal mesh can be placed in the hollow circular tube from the gap in the form of a slide rail, and the metal mesh support is provided by the abutment portion.

In order to achieve the foregoing object, the present invention provides a combined structure of a fence, including: at least one hollow circular tube, the hollow circular tube is assembled with other hollow circular tubes through a pivoting device, and the hollow circular tube has a gap, and The two edges of the notch extend toward the inside of the hollow circular tube respectively; a metal mesh, the end of the metal mesh forms a plurality of spiral portions in the form of a circle, and the diameter of the spiral portion is greater than the distance between the two resisting portions, so that the metal mesh is formed by When the gap of the hollow round pipe is inserted into the pipe fitting, it can be supported by the abutting portion by the spiral portion; and at least one cable for passing through the spiral portion and binding and fixing the two ends of the cable to the pivoting device respectively.

Based on the above, the metal mesh can be directly inserted into the hollow circular tube from the notch through the plural spiral portions while being supported by the resisting portion, and the cable passing through the spiral portion is tied to the pivoting device for fixing the hollow circular tube, thereby improving the metal mesh The stability of the assembly, and to achieve the effect of improving the operating efficiency, easy maintenance and replacement, and preventing injury to the operator.
