Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Example 1. An automatic expansion type isolation fence in a fixed area is shown in figures 1-6 and comprises a head post 1 and a tail post 2, a plurality of upright posts 4 connected through a telescopic frame 3 are arranged between the head post 1 and the tail post 2, a movable trolley 5 is arranged at the front end of the head post 1, a guide rail 6 corresponding to the movable trolley 5 is arranged below the movable trolley 5, a locking post 7 is arranged at one end of the guide rail 6, and a clamping groove 8 corresponding to the movable trolley 5 is arranged in the locking post 7.

The two sides of the guide rail 6 are provided with wheel grooves 11, and racks 12 are arranged between the wheel grooves 11.

The movable trolley 5 comprises a trolley body 10, wherein the two sides of the trolley body 10 are provided with idler wheels 9 corresponding to wheel grooves 11, the middle part of the trolley body 10 is provided with a gear 13 driven by a motor 14, the upper end of the trolley body 10 is provided with a fixing groove 18 in the vertical direction, and the front side of the fixing groove 18 is provided with a sliding groove 21.

The front end of the head post 1 is provided with a travel switch 15 for controlling the movement of the motor 14.
