Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Examples

Referring to fig. 1-4, a temporary fence includes a telescopic frame 1, a fixed support frame 3 and a movable support frame 2 are respectively disposed at two ends of the telescopic frame 1, a lead screw 4 is disposed inside the fixed support frame 3, one end of the lead screw 4 penetrates through an inner wall of the fixed support frame 3 and extends to an outer wall, the lead screw 4 is rotatably connected with a screw sleeve 5, one end of the lead screw 4, which is far away from the screw sleeve 5, is rotatably connected with a first fixed block 6, a side wall of the first fixed block 6 is fixedly connected with a side wall of the fixed support frame 3, a lower end of the movable support frame 2 is fixedly connected with a second fixed block 8, and an upper end of the movable support frame 2 is slidably connected with a sliding block 7;

the inside fixedly connected with guide bar 9 that a set of symmetry of fixed stay frame 3 set up, the lateral wall of scroll casing 5 has been seted up guide bar 9 assorted and has been led to the groove, scroll casing 5 is sliding connection with guide bar 9, through being provided with guide bar 9, can play a fine guide effect to scroll casing 5 gliding in-process from top to bottom.

The surface of fixed stay frame 3, removal support frame 2 and expansion bracket 1 all scribbles anticorrosive paint, all scribbles anticorrosive paint through setting up the surface to fixed stay frame 3, removal support frame 2 and expansion bracket 1, because anticorrosive paint has fine anticorrosion effect, avoids the rail to receive the corruption in abominable road environment for a long time, and then has reduced the life of rail.

The rotatory handle 10 of one end fixedly connected with that first fixed block 6 was kept away from to lead screw 4, the lateral wall cover of rotatory handle 10 is equipped with rubber sleeve 11, and through being provided with rotatory handle 10, the staff of being convenient for rotates lead screw 4, avoids influencing 5 lifts of scroll cover owing to rotate lead screw 4 difficulty, through setting up rubber sleeve 11, improves the staff hand and grips the travelling comfort that rotates rotatory handle 10.

The equal fixedly connected with walking wheel 12 in bottom of fixed stay frame 3 and removal support frame 2, walking wheel 12 is the universal wheel, and through setting up the equal fixedly connected with walking wheel 12 in bottom of fixed stay frame 3 and removal support frame 2, the staff of being convenient for removes this kind of rail temporarily, and through setting up walking wheel 12, the staff of being convenient for can arbitrary direction remove this kind of rail temporarily.

The working principle is as follows: before use, the temporary fence is moved to a designated position by the traveling wheels 12, and when it is required to use the temporary fence, the temporary fence is moved to a designated position by rotating the rotating handle 10, thereby driving the screw rod 4 to rotate, the screw rod 4 can drive the screw sleeve 5 to descend while rotating, further driving the telescopic frame 1 to extend, avoiding the traditional telescopic fence, when the expansion bracket 1 is expanded, one person alone is inconvenient to expand, and the expansion bracket can be opened only by the cooperation of two persons at the same time, by controlling the descending height of the screw sleeve 5, further, the telescopic length of the telescopic frame 1 can be controlled, thereby achieving the width required by adapting to different roads, greatly improving the practicability of the temporary fence, when the temporary fence is not needed, the handle 10 is rotated in the reverse direction to drive the spiral sleeve 5 to ascend, and the spiral sleeve 5 can drive the expansion bracket 1 to retract while ascending.
