[0020] Please see Figure 1-6 This utility model provides the following technical solution: a protective fence for construction projects, including a mounting base 1 and a barrier frame 3, further including a mounting frame 2 and guide rollers 4. Several threaded fixing nails 11 are installed at the bottom of the mounting base 1. Symmetrical grooves are provided on the side wall of the mounting base 1. A mounting shaft 12 is rotatably installed on the groove of the side wall of the mounting base 1. The two ends of the barrier frame 3 are installed on the mounting shaft 12 by screws. The mounting bases 1 installed at both ends of the barrier frame 3 are in a centrally symmetrical state. Several mounting rods 34 are provided on the inner wall of the barrier frame 3. Several springs 22 connected to the mounting frame 2 are installed on the side walls of the mounting rods 34. Several guide rollers 4 are installed on the opposite surface of the mounting frame 2 by torsion spring shafts. Two mounting protrusions 44 are provided on the side wall of the guide rollers 4. Baffles 43 are installed at both ends of the mounting frame 2 by torsion spring shafts. The baffles 43 and the mounting protrusions 44, as well as the opposite surfaces of adjacent mounting protrusions 44, are connected by elastic bands 41.

[0021] Mounting base 1 is used to mount the barrier frame 3. Mounting base 1 also serves as a support device, ensuring the stability of the device during use. The bottom of mounting base 1 is equipped with several casters with locking mechanisms. These casters facilitate user movement of the device, and the locking mechanisms on the casters ensure that mounting base 1 will not move during use, guaranteeing the stability of the device. Threaded fixing pins 11 are threadedly mounted on mounting base 1. When the threaded fixing pins 11 are rotated, they move along the threaded grooves under the action of the threads. As the threaded fixing pins 11 move, they penetrate into the ground, thus securing the mounting base 1 and further improving the stability of the device during use. To ensure stability during the process, the mounting shaft 12 is rotatably mounted on the side wall groove of the mounting base 1. The user can rotate the barrier frame 3 mounted on the mounting shaft 12. The position of the mounting base 1 on the barrier frame 3 ensures that multiple barrier frames 3 can be folded together. The folded barrier frames 3 reduce the space occupied by the device in the storage state, making it easier for the user to store and transport the device. The side wall of the mounting shaft 12 has a protrusion, and the side wall of the barrier frame 3 has a groove that mates with the mounting shaft 12, ensuring the stability of the barrier frame 3 after it is installed on the mounting shaft 12. The shape of the side wall groove of the barrier frame 3 ensures that the rotation angle of the barrier frame 3 is greater than 90°, making it easier for the user to store the device. The barrier frame 3 is installed on the mounting shaft 12 with screws, making it easy for the user to install the barrier frame 3. The device is easy to install and disassemble, allowing users to adjust its length according to actual usage. The barrier frame 3 is mounted on the mounting shaft 12. During use, the angle between adjacent barrier frames 3 can be adjusted, allowing users to adjust the device's position as needed. When the device is impacted, the guide roller 4 begins to rotate. The rotating guide roller 4 deflects the impact, reducing the impact on the device. The guide roller 4 is mounted on a torsion spring shaft, and its rotation is hindered by the torsion spring shaft, ensuring its effectiveness. The rotating guide roller 4 carries the mounting protrusion 44 along with it. The rotating mounting protrusion 44, via the elastic band 41, can carry the other mounting protrusions 44 and the baffle 43. As the baffle 43 and mounting protrusion 44 rotate, the elastic band 41 is stretched by the rotating baffle 43 and mounting protrusion 44. The stretched elastic band 41 and the torsion spring shafts on the driven baffle 43 and mounting protrusion 44 play a buffering role, further reducing the impact on the device. The elastic band 41 also acts as a barrier against objects impacting the device, preventing objects from passing through the device and ensuring the working effect of the device. When the impact on the device disappears, the elastic band 41, baffle 43 and mounting protrusion 44 return to their original state, ensuring the working effect of the device. When the device is impacted, the mounting frame 2 is pushed, and the pushed mounting frame 2 deforms the spring 22. The deformed spring 22 plays a buffering role.By installing several springs 22 on both side walls of the mounting rod 34, the working effect of the springs 22 is ensured. Simultaneously, the springs 22 on both sides of the mounting rod 34 also prevent the mounting frame 2 from directly impacting the mounting rod 34, reducing damage to both the mounting frame 2 and the mounting rod 34.

[0022] Specifically, mounting blocks 42 are installed at both ends of the elastic band 41, and grooves that cooperate with the elastic band 41 and mounting blocks 42 are provided on the top surface of the baffle 43 and the mounting protrusion 44.

[0023] The mounting block 42 is slidably mounted on the top surface groove of the baffle 43 and the mounting protrusion 44. The mounting method of the mounting block 42 facilitates the user's disassembly of the elastic band 41 and the replacement of the damaged elastic band 41. The side wall of the mounting block 42 is provided with a protrusion, and the side wall of the groove of the mounting block 42 is provided with a groove that matches the side wall protrusion of the mounting block 42. The cooperation between the side wall protrusion of the mounting block 42 and the matching groove plays a limiting role, preventing the elastic band 41 from detaching from the baffle 43 and the mounting protrusion 44 during the use of the device, thus ensuring the working effect of the elastic band 41.

[0024] Specifically, buffer pads are provided on the side walls of the guide roller 4, the baffle 43, and the mounting protrusion 44.

[0025] The buffer pads provided on the guide roller 4, baffle 43 and mounting protrusion 44 play a buffering role, preventing the guide roller 4, baffle 43 and mounting protrusion 44 from being damaged when subjected to impact, and extending the service life of the guide roller 4, baffle 43 and mounting protrusion 44.

[0026] Specifically, the groove through which the baffle 43 and the mounting protrusion 44 are pierced by the elastic band 41, and the edges of the baffle 43 and the mounting protrusion 44 are arc-shaped.

[0027] The shape of the edge of the groove through which the baffle 43 and the mounting protrusion 44 are penetrated by the elastic band 41 can prevent the edge of the groove through which the baffle 43 and the mounting protrusion 44 are penetrated by the elastic band 41 from causing wear on the elastic band 41, reducing the damage to the elastic band 41 during the stretching process, and extending the service life of the elastic band 41. The edge shape of the baffle 43 and the mounting protrusion 44 can also prevent outsiders from being injured when they hit the guide roller 4, the baffle 43 and the mounting protrusion 44, thus ensuring the safety of the device.

[0028] Specifically, the side wall of the mounting rod 34 is provided with several guide rods 21 that penetrate the mounting frame 2, and the guide rods 21 are positioned inside the spring 22.

[0029] The guide rod 21 serves as a guide, ensuring the stability of the mounting frame 2 during movement. The position of the guide rod 21 prevents the spring 22 from shifting during compression, ensuring the stability of the connection between the spring 22 and the mounting frame 2 and the mounting rod 34, and ensuring the working effect of the spring 22.

[0030] Specifically, the side wall of the barrier frame 3 is provided with two fixing frames 32, and fixing pins 31 are slidably installed on the fixing frames 32. The two side walls of the side wall groove of the mounting base 1 are provided with fixing grooves 33 that cooperate with the fixing pins 31.

[0031] Users can fix the barrier frame 3 by cooperating with the fixing pin 31 and the fixing groove 33, ensuring the stability of the barrier frame 3. The groove on the mounting base 1 is provided with two fixing grooves 33, which ensure that the barrier frame 3 can be fixed when the device is stored and unfolded, ensuring the working effect of the fixing pin 31. The side wall of the part of the fixing pin 31 located between the two fixing frames 32 is provided with a protrusion. The side wall protrusion of the fixing pin 31 plays a limiting role, preventing the fixing pin 31 from falling off the fixing frame 32 during movement, thus ensuring the stability of the fixing pin 31 during use.

[0032] Specifically, screws are installed on the side wall of the fixing groove 33, and the fixing pin 31 is provided with threaded holes that mate with the screws.

[0033] After the fixing pin 31 enters the fixing groove 33, the fixing pin 31 can be fixed on the fixing groove 33 by the cooperation of the screw provided on the fixing groove 33 and the threaded hole that mates with it, ensuring the stability of the fixing pin 31 and the fixing groove 33 during the use of the device. The fixing pin 31, which is fixed by the screw, also ensures the stability of the device in the storage state during transportation.

[0034] The working principle and usage process of this utility model are as follows: Move the device to a suitable position, rotate the screw on the fixing groove 33 to release the screw from fixing the fixing pin 31, release the cooperation between the fixing pin 31 and the fixing groove 33, rotate the blocking frame 3, unfold the device, after the device is unfolded, rotate the threaded fixing pin 11, the threaded fixing pin 11 enters the ground under the action of the thread, lock the universal wheel, and the device is fixed. When the guide roller 4 is impacted, the guide roller 4 rotates with the mounting protrusion 44, and the rotating mounting protrusion 44 will cause the remaining baffles 43 and mounting protrusions 44 to start rotating. As the mounting protrusion 44 rotates, the elastic band 41 is stretched. The stretched elastic band 41, along with the rotating baffle 43 and the torsion spring shaft on the mounting protrusion 44, buffer the impact on the device. When the guide roller 4 is impacted, the mounting frame 2 moves along the guide rod 21. The moving mounting frame 2 deforms the spring 22, which acts as a buffer. When the elastic band 41 is damaged, the mounting protrusion 44 or baffle 43 with the damaged elastic band 41 is rotated to move the groove of the mounting block 42 to the outside of the barrier frame 3, and then the elastic band 41 is replaced.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
