[0020] See also Figure 1-6 The utility model provides the following technical solutions: a construction protection net for construction engineering, including a shell 1, a rotating rod 2 and a drum 5, and also includes a connecting block 3 and a protective net 4. The top of the shell 1 is installed with a top plate 11 by screws, and the rotating rod 2 is rotatably installed at both ends of the shell 1. The end surface of the rotating rod 2 is provided with a cross-shaped protrusion, and the end surface of the drum 5 is installed with a mounting frame 51 by a spring. The end surface of the mounting frame 51 is provided with a groove that cooperates with the end surface protrusion of the rotating rod 2.

[0021] The housing 1 is used to place the reel 5 and the protective net 4, and the top plate 11 is used to seal the top opening of the housing 1. When the device is in use, the reel 5 is connected to the rotating rod 2 through the cooperation of the end face protrusion of the rotating rod 2 and the end face groove of the mounting frame 51. When the device is in use, the user can rotate the reel 5 by rotating the rotating rod 2. The rotating reel 5 is convenient for the user to release and reel the protective net 4. The mounting frame 51 is installed on the end face groove of the reel 5 by a spring. When the device is in use, the spring will apply pressure to the mounting frame 51, thereby improving the stability of the cooperation between the mounting frame 51 and the rotating rod 2. The diameter of the mounting frame 51 is larger than the diameter of the rotating rod 2, which is convenient for the user to push The mounting frame 51 has a protrusion on its side wall, and the side wall of the groove for mounting the mounting frame 51 is provided with a protrusion that cooperates with the protrusion on the side wall of the mounting frame 51. The groove for mounting the mounting frame 51 and the side wall protrusion provided on the mounting frame 51 cooperate to limit the position, ensuring that the mounting frame 51 will not separate from the groove for mounting the mounting frame 51 during movement, thereby ensuring the stability of the mounting frame 51 during use of the device. When the device is in use, the two shells 1 are connected together by the connection block 3 provided on the protective net 4 on one device and the connection frame 31 provided on the other device, thereby ensuring the stability of the connection between the devices during use. The side of the connection block 3 The wall is provided with a protrusion with a T-shaped cross-section, and the connecting frame 31 is provided with a groove that cooperates with the protrusion of the side wall of the connecting block 3. The shape of the protrusion of the side wall of the connecting block 3 ensures the stability of the cooperation between the connecting block 3 and the connecting frame 31, thereby ensuring the stability of the connection between the devices during the use of the devices. After the connecting block 3 is installed on the connecting frame 31, screws are installed on the threaded grooves 32 that cooperate with the connecting block 3 and the connecting frame 31 to ensure that the connecting block 3 will not slide on the connecting frame 31 during the use of the device, thereby ensuring the stability of the cooperation between the connecting block 3 and the connecting frame 31. When the net 41 is damaged, the composition of the protective net 4 is convenient for the user to repair the single piece The component net 41 can be replaced, which is convenient for users to repair damaged protective net 4 and ensures the working effect of protective net 4. The component method of protective net 4 ensures that the protective net 4 will not be obstructed in the process of winding onto the reel 5. When the component nets 41 are hinged together, the limit screw 42 is installed on the hinge shaft of the component net 41 through a thread. The difference between the diameter of the end face protrusion of the limit screw 42 and the diameter of the component net 41 ensures that the end face protrusion of the limit screw 42 plays a limiting role, ensuring that the component net 41 will not be separated from the hinge shaft of the component net 41 during the use of the device, thereby ensuring the stability of the connection between the component nets 41 during the use of the device.

[0022] Specifically, a rotating frame 43 is provided on the component net 41 at a position outside the limiting screw 42 , and the rotating frame 43 is rotatably mounted on the component net 41 .

[0023] When the protective net 4 is wound onto the reel 5, adjacent component nets 41 rotate, and the rotating frame 43 can separate the component nets 41 and the limit screws 42. The rotating frame 43 is rotatably installed on the component net 41. When the component net 41 rotates, the rotating frame 43 rotates on the component net 41. The limit screws 42 and the rotating frame 43 are in a relatively static state, ensuring that the limit screws 42 will not be rotated by the component net 41 during the rotation of the component net 41, ensuring the stability of the limit screws 42 after being installed on the rotating axis of the component net 41. The rotating frame 43 also increases the friction force on the limit screws 42, ensuring the stability of the limit screws 42 during the use of the device.

[0024] Specifically, the connecting block 3 is provided with a plurality of protrusions with a T-shaped cross-section, and the distance between the protrusions of the connecting block 3 is greater than the length of the protrusions of the connecting block 3 .

[0025] The shape of the side wall protrusion of the connecting block 3 reduces the distance that the connecting block 3 needs to be moved when the user installs the connecting block 3 on the connecting frame 31, making it easier for the user to install the connecting block 3 on the connecting frame 31. The side wall of the connecting frame 31 is provided with a groove that cooperates with the side wall protrusion of the connecting block 3, and a section of the groove that cooperates with the side wall protrusion of the connecting block 3 is provided on the groove that cooperates with the side wall protrusion of the connecting block 3, making it easier for the user to install the connecting block 3 on the connecting frame 31. The distance between the side wall protrusions of the connecting block 3 ensures that one end of the groove that cooperates with the side wall protrusion of the connecting block 3 is in a closed state, and the closed end of the side wall groove of the connecting frame 31 plays a limiting role, making it easier for the user to install the connecting block 3 on the connecting frame 31.

[0026] Specifically, a gear sleeve 22 is installed on the rotating rod 2 located inside the side wall sleeve of the shell 1, a threaded rod 21 is installed on the side wall sleeve of the shell 1, a pressure block 24 is rotatably installed at the bottom of the threaded rod 21, and a rack that cooperates with the gear sleeve 22 is provided on the bottom surface of the pressure block 24.

[0027] When the device is in use, the rotating rod 2 is fixed by the cooperation of the gear sleeve 22 and the pressure block 24, which ensures the stability of the rotating rod 2 during the use of the device, and further ensures the stability of the protective net 4 during the use of the device. When the device is in use, the length of the part of the protective net 4 extending out of the shell 1 can be adjusted according to actual use conditions through the cooperation of the gear sleeve 22 and the pressure block 24. When the protective net 4 is not fully unfolded, when the protective net 4 is impacted, the protective net 4 will not rotate with the reel 5, thereby ensuring the working effect of the protective net 4. The threaded rod 21 is installed on the protective net 4 through a thread. On the housing 1, when the user rotates the threaded rod 21, the threaded rod 21 moves with the pressure block 24 under the action of the thread. The moving pressure block 24 makes it easy for the user to control the fixation and release of the reel 5. The pressure block 24 is rotatably installed on the threaded rod 21. The cooperation between the pressure block 24 and the groove for installing the pressure block 24 plays a limiting role, ensuring that the threaded rod 21 will not be rotated by the threaded rod 21 during the rotation process, thereby ensuring the stability of the pressure block 24 during the movement process. The shape of the bottom rack of the pressure block 24 cooperates with the gear part of the gear sleeve 22, thereby ensuring the fixing effect of the pressure block 24 on the gear sleeve 22.

[0028] Specifically, a telescopic rod 23 connected to a pressing block 24 is provided on the side wall of the housing 1 where the threaded rod 21 is installed.

[0029] The telescopic rod 23 plays a role of limiting, further improving the stability of the pressing block 24 during movement. The pressing block 24 is fixed by the telescopic rod 23, which reduces the wear of the pressing block 24 during movement and extends the service life of the pressing block 24.

[0030] Specifically, matching thread grooves 32 are provided on the side walls of the connecting block 3 and the housing 1 penetrated by the protective net 4 , and screws are installed on the matching thread grooves 32 provided on the connecting block 3 and the housing 1 .

[0031] When the device is in the storage state, the connecting block 3 is fixed to the housing 1 by means of the matching thread grooves 32 and screws provided on the housing 1 and the connecting block 3, thereby ensuring the stability of the connecting block 3 when the device is in the storage state.

[0032] Specifically, a support frame 12 is provided on the inner wall of the housing 1 , and a groove that cooperates with the support frame 12 is provided on the side wall of the reel 5 .

[0033] The support frame 12 supports the reel 5 and ensures the stability of the reel 5 during rotation. The cooperation between the support frame 12 and the side wall groove of the reel 5 plays a limiting role, preventing the reel 5 from moving along the direction of the rotation axis of the reel 5 during the use of the device, thereby ensuring the stability of the cooperation between the mounting frame 51 and the rotating rod 2 during the use of the device.

[0034] The working principle and use process of the present invention are as follows: when unfolding the device, remove the connecting block 3 from the housing 1, unfold the protective net 4, connect the devices together through the cooperation of the connecting block 3 and the connecting frame 31, install the screws on the threaded groove 32 that cooperates with the connecting block 3 and the connecting frame 31, rotate the threaded rod 21, the threaded rod 21 moves down with the pressure block 24, the downward pressure block 24 cooperates with the gear part of the gear sleeve 22, and the rotating rod 2 is fixed. When the protective net 4 is damaged, remove the limit screws 42 installed on the hinge shafts at both ends of the damaged net 41, and the limit screws The fixation of the component net 41 by the nail 42 is released, the damaged component net 41 is removed, and the new component net 41 is installed on the protective net 4. When the protective net 4 is replaced as a whole, the top plate 11 is removed from the outer shell 1, and the installation frame 51 is pushed. The fit between the end face groove of the installation frame 51 and the end face protrusion of the rotating rod 2 is released, and the reel 5 is removed from the top plate 11. Then, the reel 5 wrapped with the new protective net 4 is installed on the support frame 12, and the new reel 5 is installed on the rotating rod 2 through the fit between the end face groove of the installation frame 51 and the end face protrusion of the rotating rod 2.
