Description

Technical Field

[0001] The utility model relates to a fence, in particular to a foldable combined fence. Background Art

[0002] At the scene of a traffic accident or a criminal case, in order to prevent people from destroying the scene, a cordon is usually set up to separate the area. However, the cordon only serves to separate the crowd, and people can still see what is within the cordon. Therefore, people invented fences. The existing fences are mainly composed of a fence body made of tarpaulin material and a frame supporting the fence body. A fixed seat is set in the middle of the fence body, and slots are formed around the fixed seat. Rod sleeves are set at the four corners of the fence body. When in use, one end of the multiple skeletons is inserted into the slot of the fixed seat, and the other end of the skeleton is inserted into the rod sleeve (similar to the structure of the skeleton in a kite), which supports the entire fence body. However, the disadvantages of this structure are: 1. The skeleton cannot be folded. When not in use, each supporting skeleton needs to be disassembled to fold the fence body made of tarpaulin material, which is very troublesome to operate; 2. The skeleton and the fence body are not combined after folding, and the parts are scattered and easy to lose. Summary of the invention
