[0024] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not intended to limit the scope of use of the present invention.

[0025] like Figure 1-5 As shown, the utility model proposes a retractable and movable safety fence, including a telescopic fence 7 installed between two columns 2, and the lower end of the column 2 is rotatably installed on the base 1. The column 2 is vertically installed in the middle of the base 1. Specifically, a sleeve 12 is fixedly provided on the base 1, and the lower end of the column 2 is rotatably installed on the inner bottom of the sleeve 12. A first bolt 13 is installed on the outer wall of the sleeve 12, and the end of the first bolt 13 passes through the sleeve 12 and is tightly pressed against the column 2. The first bolt 13 can be a hand-tightened bolt, which is more convenient to use. When there is an installation angle between two adjacent fences, the base 1 can be rotated to make the two adjacent bases 1 of the two fences close to each other side by side and locked and fixed by the first bolt 13, so that the connection between the two fences can be tighter and the structure can be more stable.

[0026] A universal wheel 11 is installed below the base 1, which makes it easier to move the fence. A rotating drum 3 is coaxially rotatably sleeved on the middle part of the column 2 and fixed by a first locking member. The two ends of the rotating drum 3 are coaxially rotatably mounted on the column 2 through bearings, and pin holes 20 are equidistantly provided along the circumferential direction of the column 2. The ends of the pins 31 installed on the outer wall of the rotating drum 3 penetrate the rotating drum 3 and are inserted into the pin holes 20. A tension spring 32 is sleeved on the pin 31, and the two ends of the tension spring 32 are respectively fixed to the outer end of the pin 31 and the outer wall of the rotating drum 3. Pull the pin 31 outward to stretch the tension spring 32, and rotate the rotating drums 3 on the two adjacent columns 2 according to the connection angle between the two adjacent fences. The plug-in portion of the rotating drum 3 on the column 2 corresponds to the socket 40 of the rotating drum 3 on the adjacent column 2. Under the elastic force of the tension spring 32, the pin 31 is inserted into the corresponding pin hole 20 to achieve locking of the rotating drum 3.

[0027] A plug-in portion is fixedly provided on one side of the outer wall of the rotating drum 3, and a fixed block 4 is provided on the other side. A socket 40 is vertically provided on the fixed block 4, and a clamping portion that matches the plug-in portion of the upright post 2 on the adjacent fence is provided in the socket 40. Specifically, the clamping portion includes a clamping plate 61, a spring 62, and a push rod 64. A first movable groove 41 is provided inside the socket 40, and a second movable groove 42 is provided inside the first movable groove 41, and the clamping plate 61 is slidably clamped in the first movable groove 41. The plug-in portion includes a plug-in plate 5 vertically fixed on the other side of the rotating drum 3, and the plug-in plate 5 on the corresponding upright post 2 of the adjacent fence is inserted into the socket 40, and a clamping port that matches the plug-in plate 61 is provided on the plug-in plate 5. The ends of the plug plate 5 and the card plate 61 corresponding to each other are provided with mutually matching inclined surfaces. When the plug plate 5 is pressed into the socket 40, the two inclined surfaces can push the card plate 61 into the first movable groove 41, so that the card plate 61 shrinks into the first movable groove 41, which makes it easier for the plug plate 5 to be inserted into the socket 40. The card plate 61 is fixedly connected to one end of the limit rod 63 away from the plug plate 5. The limit rod 63 is sleeved with a spring 62, and the two ends of the spring 62 are respectively abutted against the card plate 61 and the inner wall of the first movable groove 41; the other end of the limit rod 63 penetrates and extends into the second movable groove 42 and is fixedly connected to the push rod 64. The end of the push rod 64 extending out of the second movable groove 42 is provided with a pressure-applying portion 641. Among them, the push rod 64 is L-shaped, and the push rod 64 is horizontally arranged in the second movable groove 42, one end of which is vertically fixedly connected to the limit rod 63, and the other end extends to the outside of the fixed block 4 away from the first movable groove 41. The push rod 64 is arranged on the side of the fixing block 4 to avoid affecting the installation and fixation of the plug board 5.

[0028] The push rod 64 is pressed by the pressure part 641, so that the push rod 64 moves with the limit rod 63 and the card plate 61 away from the plug plate 5 and compresses the spring 62 until the card plate 61 is disengaged from the card slot on the plug plate 5, so that the card plate 61 can be pulled out from the socket 40 and contact the fixation between two adjacent columns 2. When the two adjacent columns 2 are fixedly connected, it is only necessary to insert the plug plate 5 on the rotating drum 3 on the two columns 2 that has been rotated and adjusted to an angle into the socket 40 of the fixing block 4 on the other column 2. Under the cooperation of the inclined surface, the card plate 61 will first retract into the first movable groove 41, and under the elastic force of the spring 62, the card plate 61 will be inserted into the card slot to fix the plug plate 5, thereby realizing the fixed connection between the two columns 2.

[0029] The base 1 is provided with a connecting piece connected to the base 1 of the adjacent fence. The connecting piece includes a connecting piece 8 and a hanging nail 12 provided above the base 1. A hook is provided at one end of the connecting piece 8, and the hook cooperates with the hanging nail 12 on the base 1 of the adjacent fence. A strip groove 80 is provided in the middle of the other end of the connecting piece 8. A second bolt 81 penetrates the strip groove 80 and is downwardly installed on the base 1 and is crimped and fixed with the connecting piece 8. Rotate and adjust the connecting piece 8 so that the hook of the connecting piece 8 is hung on the hanging nail 12, and then tighten the second bolt 81 to achieve a fixed connection between the two bases 1, which is very simple and convenient to use.

[0030] When using the utility model, firstly, two adjacent bases 1 of different fences are rotated and adjusted according to the angle between the two adjacent fences, so that they are aligned and close together, and the column 2 on the base 1 is locked by the first bolt 13, and then the pin 31 is used to rotate and adjust the angle of the rotating drum 3 on the adjacent column 2 of the different fences, so that the plug plate 5 on one of the rotating drums 3 is correspondingly inserted into the socket 40 of the other rotating drum 3, and locked by the structure of the clamping plate 61 and the spring 62, and finally the two adjacent bases 1 are fixedly connected by a connecting piece.
