DETAILED DESCRIPTION

[0023] The embodiments described below are only a part of the embodiments of the utility model, and do not represent all the embodiments consistent with the utility model. Now, combining with the drawings, the exemplary embodiments are described as follows:

[0024] As Figures 1-5 The utility model construction safety protection device, it includes first stand 1, the top of first stand 1 is equipped with second stand 2, both bottom left and right sides outer walls of first stand 1 and second stand 2 are welded with fixed foot stool 3, the outside of first stand 1 is provided with connecting rod assembly 5, the top front outer wall of first stand 1 is provided with operation cavity 6, the inside of the top of first stand 1 is provided with storage cavity 7, the inside of storage cavity 7 is installed with positioning assembly 8, the bottom of second stand 2 is provided with positioning groove 9, and the length and width of positioning groove 9 and storage cavity 7 are consistent.

[0025] On the basis of the above structure, the longitudinal section of fixed foot stool 3 is triangular structure, and bolt hole 4 is arranged at the middle position of the bottom end of fixed foot stool 3.

[0026] In the embodiment, first stand 1 and second stand 2 are fixedly installed on the ground by fixed foot stool 3 and bolt hole 4.

[0027] On the basis of the above structure, connecting rod assembly 5 includes first protective rod 51 and second protective rod 52, first protective rod 51 and second protective rod 52 are both provided with two front and back symmetries, and first protective rod 51 and second protective rod 52 are respectively located at the left and right sides of first stand 1.

[0028] On the basis of the above structure, the length of first protective rod 51 and second protective rod 52 is equal, and they are always in parallel state, and the two ends of first protective rod 51 and second protective rod 52 are respectively hinged with first stand 1 and second stand 2.

[0029] In this embodiment, the first protective rod 51 and the second protective rod 52, which are of equal length and arranged in parallel with each other, facilitate the movement of the second column 2 to form a height difference with the first column 1. The height difference can be adjusted according to the actual installation environment so that the device can be used for protective installation on staircases of various sizes and on flat floors.

[0030] Based on the above structure, the positioning component 8 includes a trapezoidal lead screw 81, a handle 82, and a square rod 83. The trapezoidal lead screw 81 is bearing-mounted inside the top of the first column 1. The bottom of the trapezoidal lead screw 81 is fixedly connected to the handle 82, which is located inside the operating cavity 6. The outer thread of the threaded section of the trapezoidal lead screw 81 is threaded with the square rod 83, which is engaged and slidably located inside the storage cavity 7.

[0031] Based on the above structure, the dimensions of the square rod 83 and the positioning groove 9 are mutually compatible.

[0032] In this embodiment, by controlling the rotation of the trapezoidal lead screw 81 to raise the square rod 83 and insert it into the positioning slot 9, the first column 1 and the second column 2 can be positioned, which facilitates the folding and recycling of the device, makes the device more reusable, and enhances its practicality.

[0033] The working principle of this utility model is as follows:

[0034] In use, first hold the handle 82 to control the rotation of the trapezoidal lead screw 81, causing the square rod 83 to retract into the storage cavity 7 and disengage from the positioning groove 9, thus releasing the positioning of the second column 2. Then, using the first protective rod 51 and the second protective rod 52, which are of equal length and parallel to each other, the second column 2 can be pushed into a stable vertical position and moved diagonally downward to the right. This allows the device to be moved from... Figure 1 The state is adjusted as shown. Figure 2 As shown, there is a height difference between the first column 1 and the second column 2, and this height difference can be adjusted according to the actual installation environment so that the device can be used for installation on staircases and flat floors of various specifications, which is convenient for construction safety protection. Then, by fixing the device to the ground through the bolt hole 4 in the middle of the fixed bracket 3 and using existing means, it can provide construction safety and fall protection for workers.

[0035] After construction is completed, the device can be removed from the ground and restored to its original position. Figure 1 In the state shown, the trapezoidal screw 81 is reversed to control the square rod 83 to rise, and the top of the square rod 83 is inserted into the positioning groove 9. This allows for positioning between the first column 1 and the second column 2, facilitating the folding and recycling of the device and making it more practical for repeated use.

[0036] The above is only a preferred embodiment of the present application, and does not limit the scope of protection of the present application; any equivalent changes, modifications, replacements and variations made by logical analysis, reasoning or limited experiments on the basis of the prior art according to the concept of the present application should be within the protection scope determined by the claims.
