Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Please refer to Figure 1 and Figure 4, the present utility model provides a technical solution: a protective net for construction engineering, including a U-shaped column 1. On one side of the U-shaped column 1, there is a slot 2. The inner wall of the slot 2 is provided with an insertion plate 3. On the side where the two insertion plates 3 are close to each other, a protective net body 4 is fixedly connected. At the front end of the U-shaped column 1, a disassembly mechanism 5 is fixedly connected. At the lower end of the U-shaped column 1, a base 6 is fixedly connected. At the rear end of the U-shaped column 1, a support mechanism 7 is fixedly connected. The disassembly mechanism 5 includes an unlocking box 51. The rear end of the unlocking box 51 is fixedly connected to the front end of the U-shaped column 1. The inner wall of the unlocking box 51 is provided with a push plate 52. At the front end of the push plate 52, there is a pressing block 53. At the rear end of the push plate 52, a pressing rod 54 is fixedly connected. A first spring 55 is sleeved on the outer wall of the pressing rod 54. One end of the pressing rod 54 contacts an insertion block 56. At the rear end of the insertion block 56, a second spring 57 is fixedly connected. The outer wall of the insertion block 56 is sleeved with a fixing box 58. The outer wall of the slot 2 is embedded and connected to one side of the U-shaped column 1. The inner wall of the slot 2 is slidably connected to the outer wall of the insertion plate 3;

[0024] On both sides of the protective net body 4, insertion plates 3 adapted to the slots 2 are fixedly connected. On the side of the insertion plate 3 away from the protective net body 4, there are two fixing boxes 58. In the inner cavity of the fixing box 58, there is a second spring 57. One end of the second spring 57 is fixedly connected to the inner wall of the fixing box 58, and the other end of the second spring 57 is fixedly connected to an insertion block 56. The shape of the insertion block 56 is a triangular trapezoidal structure and is adapted to the corresponding end of the pressing rod 54.

[0025] Please refer to Figure 2 , in order to quickly install and fix the protective net body 4 in the U-shaped column 1, the inner wall of the unlocking box 51 is slidably connected to the outer wall of the push plate 52. The front end of the push plate 52 is fixedly connected to the rear end of the pressing block 53. One side of the fixing box 58 is fixedly connected to one side of the insertion plate 3 and is slidably arranged in the slot 2;

[0026] When it is necessary to install the protective net body 4, the user only needs to insert the protective net body 4 into the slot 2 of the U-shaped column 1 under the arrangement of the two insertion plates 3. Under the elastic action of the second spring 57, the insertion block 56 is clamped with the U-shaped column 1. When it is necessary to disassemble the protective net body 4, the user only needs to press the pressing block 53. The pressing block 53 drives the push plate 52 to move along the inner wall of the unlocking box 51. The movement of the push plate 52 causes the pressing rod 54 to press the insertion block 56 into the fixing box 58, so that the insertion block 56 is separated from the U-shaped column 1, achieving the purpose of facilitating the disassembly of the protective net body 4. The operation is convenient, without the need for additional bolts and nuts for fixation, saving a large amount of time and manpower, and improving work efficiency.

[0027] Please refer to Figure 3, in order to quickly assist in supporting the U-shaped column 1 and the protection net body 4, the support mechanism 7 includes a first support 71. The front end of the first support 71 is fixedly connected to the rear end of the U-shaped column 1. The inner side wall of the first support 71 is provided with a sleeve 72. The upper end of the sleeve 72 is provided with a rectangular hole 73. A sleeve rod 74 is inserted into the inner wall of the sleeve 72. The upper end of the sleeve rod 74 is fixedly connected to a locking rod 75. The outer wall of the locking rod 75 is threadedly connected to a locking nut 76. One end of the sleeve rod 74 is hinged to a second support 77. One side of the second support 77 is fixedly connected to a support base 78. The inner side wall of the first support 71 and one end of the sleeve 72 are rotatably connected through a rotating shaft. The upper end of the sleeve 72 is connected through the outer wall of the rectangular hole 73. The bottom of the support base 78 is fixedly connected with a number of metal bumps;

[0028] When it is necessary to assist in supporting the protection net body 4, the user takes out the sleeve rod 74 from the sleeve 72. By pulling the sleeve rod 74, the sleeve rod 74 moves along the inside of the sleeve 72, so that the bottom support base 78 contacts the ground. Then the locking nut 76 is tightened, so that the locking nut 76 is screwed tightly with the outer wall of the locking rod 75, and the locking nut 76 firmly abuts against the upper end surface of the sleeve 72. Thus, the U-shaped column 1, the sleeve 72, the sleeve rod 74 and the ground form a triangle, so that the protection net body 4 is more stable during use, improving the force stability of the protection net during use, and avoiding the protection net from being easily toppled backward after being subjected to a certain impact, causing damage to the overall protection net. When it is necessary to disassemble, the user rotates the locking nut 76 in the opposite direction, so that the locking nut 76 no longer abuts against the sleeve 72. Then the sleeve rod 74 is retracted into the sleeve 72, and the locking nut 76 is tightened to complete the storage.

[0029] Working principle: First, both sides of the protection net body 4 are fixedly connected with insertion plates 3 adapted to the slots 2. And two fixed boxes 58 are arranged on the side of the insertion plate 3 away from the protection net body 4. A second spring 57 is arranged in the inner cavity of the fixed box 58. One end of the second spring 57 is fixedly connected to the inner wall of the fixed box 58, and the other end of the second spring 57 is fixedly connected to a plug 56. The shape of the plug 56 is a triangular trapezoid structure and is adapted to the corresponding end of the pressing rod 54. When it is necessary to install the protection net body 4, the user only needs to insert the protection net body 4 into the slot 2 of the U-shaped column 1 under the arrangement of the two insertion plates 3. Under the elastic action of the second spring 57, the plug 56 is clamped with the U-shaped column 1. When it is necessary to disassemble the protection net body 4, the user only needs to press the pressing block 53, and the pressing block 53 drives the push plate 52 to move along the inner wall of the unlocking box 51. The movement of the push plate 52 causes the pressing rod 54 to press the plug 56 into the fixed box 58, so that the plug 56 is separated from the U-shaped column 1, achieving the purpose of facilitating the disassembly of the protection net body 4. The operation is convenient, without the need for additional bolts and nuts for fixation, saving a large amount of time and manpower and improving work efficiency;

[0030] Then, when auxiliary support for the protection net body 4 is required, the user takes out the sleeve rod 74 from the sleeve 72. By pulling the sleeve rod 74, the sleeve rod 74 moves along the inside of the sleeve 72, making the bottom support base 78 contact the ground. Then, the locking nut 76 is tightened so that the locking nut 76 is screwed tightly on the outer wall of the locking rod 75, and the locking nut 76 firmly abuts against the upper end face of the sleeve 72. Thus, the U-shaped column 1, the sleeve 72, the sleeve rod 74, and the ground form a triangle, making the protection net body 4 more stable during use, improving the force stability of the protection net during use, and preventing the protection net from easily tipping backward after being subjected to a certain impact, which may cause damage to the entire protection net. When disassembly is required, the user rotates the locking nut 76 in the reverse direction so that the locking nut 76 no longer abuts against the sleeve 72. Then, the sleeve rod 74 is retracted into the sleeve 72, and the locking nut 76 is tightened to complete the storage. The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
