[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Embodiment 1

[0029] See also Figure 1-4, a protective device for municipal engineering, comprising a main body component 1; the main body component 1 comprises a column 11, and a protective plate 12 is arranged on the opposite surface of the column; a disassembly component 2 is arranged on the protective plate 12, and the disassembly component 2 comprises: a pressing block 21, which is inserted into the interior of the protective plate 12 and is slidably connected to the interior of the protective plate 12; a moving block 22, which is fixedly connected to the interior of the protective plate 12 and is slidably connected to the interior of the protective plate 12; an L-shaped rod 23, which is arranged on the outside of the moving block 22, and two are symmetrically arranged; a slider 24, one end of each of the L-shaped rods 23 is fixedly connected to the slider 24, and each of the sliders 24 is slidably connected to the interior of the moving block 22; a limit block 25, each of the outer sides of the L-shaped rods 23 is fixedly connected to the limit block 25; a limit groove 26, a limit groove 26 is provided inside each of the columns 11; a spring 26 is arranged inside the protective plate 12, and the two ends of the spring 26 are respectively fixedly connected to the bottom of the moving block 22 and the interior of the protective plate 12.

[0030] When ready for use, the operator places the column 11 at the designated position. When the protective net on the protective plate 12 needs to be replaced or cleaned, the operator pulls the pressing block 21 upward, and the movement of the pressing block 21 drives the moving block 22 to move upward at the same time. The movement of the moving block 22 drives the slider 24 to slide in the slide groove of the moving block 22, and the movement of the slider 24 drives the L-shaped rod 23 to move at the same time, so that the L-shaped rod 23 drives the limit block 25 to slide into the protective plate 12, and then the operator pulls the protective plate 12 upward to separate the protective plate 12 from the column 11, thereby fixing the protective plate 12. The protective net on the protective plate 12 needs to be replaced or cleaned. When installing it again, the operator places the protective plate 12 between the two columns 11, and then presses the pressing block 21 downward. The pressing block 21 drives the limiting block 25 to enter the limiting groove 26, thereby completing the installation. The operation is simple and the work efficiency of the operator is improved. A spring 26 is arranged inside the protective plate 12, so that when the operator installs the protective plate 12, he only needs to loosen the pressing block 21. Under the action of the spring 26, the spring 26 automatically pulls the pressing block 21 down, and the operator does not need to press it manually, thereby improving the convenience of the device.

[0031] Embodiment 2

[0032] See also Figure 1-4 , based on the first embodiment, a fixed function is added;

[0033] A fixing assembly 3 is provided on the protective plate 12, and the fixing assembly 3 includes: a fixing plate 31, fixedly connected to the top of the protective plate 12; a pull rod 32, penetrating the fixing plate 31, and slidably connected to the fixing plate 31; a fixing sleeve 33, fixedly connected to the outer wall of the pull rod 32; a spring 34, provided on the fixing sleeve 33, and fixedly connected to the outer wall of the fixing sleeve 33 and the outer wall of the fixing plate 31 on both sides; a fixing groove 35, opened on the outer wall of the pressure block 21; a groove 5 is opened on the outer wall of the pull rod 32, and a plurality of grooves are evenly arranged; each of the limit blocks 25 is provided with an arc surface; the outer wall of the column 11 on one side is symmetrically fixedly connected with a positioning plate 4.

[0034] When in use, when the pressure block 21 moves downward, the pull rod 32 always slides on the surface of the pressure block 21. When the limit block 25 enters the limit groove 26, under the pull of the spring 34, the fixing sleeve 33 moves toward the pressure block 21, and drives the pull rod 32 to move toward the inside of the fixing groove 35 on the fixing plate 31 at the same time, so that the pull rod 32 is inserted into the fixing groove 35, thereby preventing the user from accidentally touching the pressure block 21 when the device is in use, resulting in an unstable connection between the protective plate 12 and the column 11, thereby causing the protective plate 12 to fall off and injure the user, thereby improving the safety of the device; a groove 5 is provided on the outer wall of the pull rod 32. When the operator removes the protective plate 12, the operator needs to pull the pull rod 32 out of the fixing groove 35 first. When pulling, the operator can increase the friction between the pull rod 32 and the operator's fingers through the groove 5, thereby preventing the elastic potential energy of the spring 34 from The protective plate 12 is relatively large, and the surface of the pull rod 32 is too smooth, which causes the pull rod 32 to detach, and the operator needs to pull it again, thereby providing convenience for the device; each limit block 25 is provided with an arc surface, so that when the operator installs the protective plate 12 from top to bottom, the edge of the column 11 squeezes one side of the arc surface of the limit block 25, and squeezes the limit block 25 into the interior of the protective plate 12 to prevent the operator from pulling the pressure block 21 with one hand and pulling the protective plate 12 downward with the other hand during installation, which is inconvenient; the outer wall of the column 11 is symmetrically provided with a positioning plate 4, and the operator can put the protective plate 12 into the correct position through the positioning plate 4, so that the limit block 25 is aligned with the limit groove 26, to prevent the protective plate 12 from blocking the limit groove 26 on the column 11 during installation, and the operator needs to rely on experience to align, thereby improving the work efficiency of the operator.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
