[0022] Example:

[0023] like Figure 1-3As shown, a safety fence for construction includes a bottom plate 1, a fixing groove 2 is provided at the top of the bottom plate 1, grooves 3 are provided on the inner walls on both sides of the fixing groove 2, the same fixing rod 4 is fixedly installed on the top inner wall and the bottom inner wall of the groove 3, the same lifting plate 6 is slidably installed on the two fixing rods 4, one end of a first spring 5 is fixedly installed at the bottom of the lifting plate 6, the other end of the first spring 5 is fixedly installed on the bottom inner wall of the fixing groove 2, a mounting plate 7 is provided on the top of the lifting plate 6, the top of the mounting plate 7 extends to the outside of the fixing groove 2 and is fixedly installed with a fence 8, and the inner walls on both sides of the fixing groove 2 are provided with a fixing plate 7. A slide groove is provided, a connecting groove 16 is provided on the inner wall at the bottom of the slide groove, the same fixing column 17 is fixedly installed on the inner walls on both sides of the connecting groove 16, a sliding seat 18 is slidably installed on the fixing column 17, one end of a second spring 19 is fixedly installed on one side of the sliding seat 18, and the other end of the second spring 19 is fixedly installed on the inner wall of the connecting groove 16, the top of the sliding seat 18 extends into the slide groove and a wedge block 13 is fixedly installed, and a handle 15 is fixedly installed on the top of the wedge block 13, and two symmetrically arranged fixing holes are provided on the top of the base plate 1, and the top of the handle 15 extends to the outside of the fixing hole.

[0024] In the present invention, the number of the first springs 5 ​​is five to ten, and the five to ten first springs 5 ​​are arranged at equal intervals. The arrangement of the plurality of first springs 5 ​​enables the mounting plate 7 to be installed more stably.

[0025] In the utility model, a sliding hole is opened on the top of the lifting plate 6, and a sealing ring is provided on the side wall of the sliding hole. The lifting plate 6 is sealed and connected to the sliding hole through the sealing ring. The setting of the sealing ring can reduce the friction force on the lifting plate 6 when it is lifted or lowered, thereby facilitating the lifting of the lifting plate 6.

[0026] In the utility model, both sides of the mounting plate 7 are provided with a card slot 12, and one side of the wedge block 13 extends to the card slot 12 and is clamped with the card slot 12. Through the clamping arrangement of the card slot 12 and the wedge block 13, when the wedge block 13 is clamped into the card slot 12, the mounting plate 7 can be well limited.

[0027] In the utility model, connecting seats 9 are fixedly installed on both sides of the fence 8, and screws 10 are provided on the connecting seats 9. A threaded groove 11 is opened on the top of the bottom plate 1. The bottom end of the screw 10 extends into the threaded groove 11 and cooperates with the threaded groove 11.

Through the coordinated setting of the screw rod 10 and the thread groove 11, when the screw rod 10 is inserted into the thread groove 11, the connecting seat 9 can be well limited.

[0029] Working principle: during installation, the fence net 8 is pushed, and the fence net 8 can drive the mounting plate 7 to move up and down. The lifting and lowering of the mounting plate 7 can squeeze the lifting plate 6, so that the lifting plate 6 squeezes the first spring 5, so that the first spring 5 is in a compressed state, and when the mounting plate 7 moves, the mounting plate 7 squeezes the wedge block 13 in return, so that the wedge block 13 moves, and the movement of the wedge block 13 can compress the second spring 19, so that the second spring 19 is in a compressed state. When the wedge block 13 is inserted into the card slot 12, the wedge block 13 can be locked under the elastic force of the second spring 19. The screw rod 10 is inserted into the card slot 12, thereby completing the limitation of the mounting plate 7, and through the coordinated arrangement of the screw rod 10 and the threaded groove 11, when the screw rod 10 is inserted into the threaded groove 11, the connecting seat 9 can be well limited, thereby completing the installation of the fence 8. When disassembling, the screw rod 10 is rotated to move the screw rod 10 to the outside of the threaded groove 11. At this time, the handle 15 is pulled to move the wedge block 13 to the outside of the card slot 12. At this time, the limitation of the mounting plate 7 can be released, thereby completing the disassembly of the fence 8, which is convenient for people to use.

[0030] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
