DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] Example 1: Refer to the attached instructions Figure 1-3 The utility model is a protective device for municipal engineering construction, including a support rod 1, see Figure 3 The support rod 1 is inserted with an insertion rod 2, and the interior of the insertion rod 2 is rotatably connected to a hinge 3. The outer wall of the hinge 3 is rotatably connected to multiple first vertical rods 4 and second vertical rods 5. Multiple first vertical rods 4 and second vertical rods 5 are staggered in sequence. A slide groove 6 is opened inside the insertion rod 2 and the second vertical rod 5. A scissor-type connector 7 is inserted inside the slide groove 6. The scissor-type connector 7 is rotatably connected to the interior of the first vertical rod 4;

[0019] The support rod 1 is internally plugged with a connector 8, a threaded groove 9 is provided inside the support rod 1, a positioning slot 10 is provided at the top of the support rod 1, a fixing member 11 is inserted inside the positioning slot 10, the fixing member 11 is provided at the top of the support rod 1, the top of the fixing member 11 is rotatably connected to a knob 12, the bottom of the knob 12 is fixedly connected to a threaded rod 13, and the threaded rod 13 is threadedly connected to the inside of the threaded groove 9, see Figure 2 A fixing plate 14 is fixedly installed on one side of the support rod 1.

[0020] When the staff needs to fence off the construction area of ​​the municipal project, first one staff member places the support rod 1 in the appropriate position, and then another staff member pulls the other support rod 1 to make the two support rods 1 move away from each other, and then the inserted rod 2 inside the support rod 1 moves away from each other, and the inserted rod 2 pulls the scissor-type connector 7 through the slide 6 to deform and expand the scissor-type connector 7. The expansion of the scissor-type connector 7 drives the support rod 1, the first vertical rod 4, and the second vertical rod 5 to all expand synchronously until the length of the protective device reaches the required length and stops. At this time, the staff can insert the fastener into the interior of the fixing plate 14 to fix the protective device to achieve the effect of quickly adjusting the overall length of the protective device to adapt to different situations. This can effectively prevent the traditional fence from being uniform in size, resulting in the situation that if one more piece is put, the protection range will be exceeded, and if one less piece is put, the place that needs protection cannot be protected. In addition, the protective device is in a retracted state and occupies a small area, which is convenient for the staff to carry, convenient for the staff to carry and transport the protective device, and improves the user experience of the protective device.

[0021] Furthermore, the worker can turn the knob 12 so that the knob 12 drives the threaded rod 13 to rotate and disengage from the interior of the support rod 1, thereby causing the threaded rod 13 to push the fixing piece 11 out of the interior of the positioning slot 10. At this time, the worker can insert the connecting piece 8 on another protective device into the interior of the support rod 1 of this protective device, and align and insert the fixing piece 11 into the positioning slot 10 at the top of the support rod 1. Then, the worker turns the knob 12 so that the knob 12 drives the threaded rod 13 to be connected to the interior of the support rod 1 through threads, thereby causing the threaded rod 13 to drive the fixing piece 11 to be pressed into the interior of the positioning slot 10 at the top of the support rod 1, so that the two protective devices are fixed together through the connecting piece 8, so as to achieve quick connection and fixation of the protective devices, which is convenient for the worker to protect the construction area according to needs and prevent people from entering the dangerous area without paying attention.

[0022] Furthermore, when the staff needs to remove the protective device, they can remove the fasteners from the inside of the fixing plate 14 and the ground to stop fixing the protective device, and then turn the knob 12 to finally stop the fixing part 11 from being fixed on the top of the support rod 1, so that multiple protective devices can be separated in sequence. Then the staff can gradually retract the protective device until the support rod 1, the first vertical pole 4, and the second vertical pole 5 are retracted to a certain extent and then stop, so that the protective device is retracted to reduce the footprint, making it easier for the staff to carry.
