DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an embodiment of the present invention provides a construction safety protection device, comprising two safety guardrails 1 and two positioning shells 2. The right side of the positioning shell 2 is fixedly connected to the left side of the safety guardrail 1. The right side of the safety guardrail 1 is fixedly connected to a positioning frame 3 used in conjunction with the positioning shell 2. The surface of the positioning shell 2 is in contact with the inner cavity of the positioning frame 3. The inner cavity of the positioning shell 2 is movably connected to a control rotating rod 4. The top of the control rotating rod 4 passes through the positioning shell 2 and extends to the outside of the inner cavity of the positioning shell 2. A positioning device 5 is provided inside the positioning shell 2.

[0022] refer to Figure 4 The positioning device 5 includes two positioning boxes 501. The opposite sides of the two positioning boxes 501 pass through the positioning shell 2 and extend to the outside of the inner cavity of the positioning shell 2. The inner cavity of the positioning box 501 is fixedly connected with a spring 502. The bottom of the inner cavity of the positioning shell 2 is fixedly connected with two positioning blocks 503 used in conjunction with the positioning boxes 501. The surface of the positioning block 503 is movably connected to the inner cavity of the positioning box 501, and the surface of the spring 502 is fixedly connected to the surface of the positioning block 503.

[0023] With the above solution, by providing the positioning device 5 , when two safety guardrails 1 need to be connected, the positioning device 5 has a connecting effect on the position of the safety guardrails 1 .

[0024] refer to Figure 4 The surface of the positioning box 501 is fixedly connected to the extrusion plate 6, and the inner cavity of the positioning shell 2 is movably connected to the mobile extrusion block 7 used in conjunction with the extrusion plate 6, and the surface of the mobile extrusion block 7 contacts the surface of the extrusion plate 6.

[0025] The above solution is adopted: by providing the extrusion plate 6 and the movable extrusion block 7, when the movable extrusion block 7 moves, an extrusion force can be generated on the extrusion plate 6, and the extrusion plate 6 subjected to the extrusion force can drive the positioning frame 501 to move.

[0026] refer to Figure 4 The surface of the movable extrusion block 7 is fixedly connected to the outer auxiliary shell 8, the inner cavity of the outer auxiliary shell 8 is movably connected to the inner auxiliary shell 9, and the surface of the inner auxiliary shell 9 is fixedly connected to the inner cavity of the positioning shell 2.

[0027] The above solution is adopted: by setting an external auxiliary shell 8 and an internal auxiliary shell 9, when the movable extrusion block 7 moves, the external auxiliary shell 8 will be driven to move along the surface of the internal auxiliary shell 9. The coordinated use of the external auxiliary shell 8 and the internal auxiliary shell 9 has a limiting effect on the moving position of the movable extrusion block 7.

[0028] refer to Figure 4 The surface of the control rotating rod 4 is fixedly connected with an extrusion rotating plate 10 used in conjunction with the mobile extrusion block 7, and the surface of the extrusion rotating plate 10 contacts the surface of the mobile extrusion block 7.

[0029] The above solution is adopted: by setting the extrusion rotating plate 10, when the extrusion rotating plate 10 rotates, it can generate pressure on the mobile extrusion block 7, and the extrusion force generated by the extrusion rotating plate 10 on the mobile extrusion block 7 can drive the mobile extrusion block 7 to move.

[0030] refer to Figure 3 The front and rear sides of the inner cavity of the positioning frame 3 are both provided with positioning grooves 11 for use with the positioning square frame 501 , and the surface of the positioning square frame 501 contacts the inner cavity of the positioning grooves 11 .

[0031] The above solution is adopted: by setting the positioning groove 11, when the positioning shell 2 moves to the inner cavity of the positioning frame 3, the control lever 4 is released, and the restoring force generated by the spring 502 restoring its shape will drive the positioning frame 501 to be stuck into the inner cavity of the positioning groove 11. The coordinated use of the positioning frame 501 and the positioning groove 11 has a limiting effect on the position of the positioning shell 2 and the safety guardrail 1.

[0032] refer to Figure 2 The left side of the safety fence 1 is fixedly connected to a plug rod 12, and the right side of the safety fence 1 is fixedly connected to a plug shell 13 used in conjunction with the plug rod 12. The surface of the plug rod 12 contacts the inner cavity of the plug shell 13.

[0033] The above solution is adopted: by setting the plug-in rod 12 and the plug-in shell 13, when the plug-in rod 12 moves to the inner cavity of the plug-in shell 13, the positioning shell 2 moves into the inner cavity of the positioning frame 3. The coordinated use of the plug-in rod 12 and the plug-in shell 13 increases the stability of the connection between the two safety guardrails 1.

[0034] The working principle of this utility model:

[0035] During use, when the safety guardrail 1 for construction needs to be connected more stably, the user first rotates the control lever 4 to the front side. When the control lever 4 rotates, the extrusion rotating plate 10 will be driven to rotate along the surface of the movable extrusion block 7. The movable extrusion block 7 subjected to the extrusion force will move along the surface of the extrusion plate 6. When the movable extrusion block 7 moves, the outer auxiliary shell 8 will be driven to move along the surface of the inner auxiliary shell 9. At the same time, the extrusion force generated by the movable extrusion block 7 on the extrusion plate 6 will drive the two extrusion plates 6 to move toward each other. When the extrusion plate 6 moves, the two positioning boxes 501 will be driven along the surface of the positioning block 503. When the positioning box 501 is completely moved to the inner cavity of the positioning shell 2, the plug-in rod 12 is moved to the inner cavity of the plug-in shell 13, and the positioning shell 2 is driven to move into the inner cavity of the positioning frame 3. Then the control lever 4 is released, and the restoring force generated by the spring 502 restoring its shape will drive the positioning box 501 to be stuck in the inner cavity of the positioning groove 11. The coordinated use of the positioning box 501 and the positioning groove 11 has a limiting effect on the position of the positioning shell 2 and the safety guardrail 1. At this time, the safety guardrail 1 for construction completes a more stable connection.

[0036] In summary: the construction safety protection device solves the problem that the existing construction safety guardrail is a safety protection device used for construction sites by setting a positioning device 5, a positioning box 501, a spring 502, a positioning block 503 and a positioning groove 11. When used, multiple guardrails are usually connected with bolts, and then the connected guardrails are used to enclose the construction area. One of the main defects of the bolt connection is loose bolts. The loose bolts may be caused by improper installation, too long use time or load exceeding the design range. The loose bolts reduce the stiffness and strength of the connection part, thereby causing the safety guardrail connection to be unstable. However, the existing construction safety guardrail does not have a component for more stable connection.
