Description

Technical Field

[0001] This utility model relates to the field of engineering construction protection technology, and in particular to a protective device for construction engineering. Background Technology

[0002] In the process of engineering construction, in order to separate the work area and the activity area and avoid the two areas from being connected and causing construction safety hazards, workers usually set up protective fences around the construction area or dangerous construction equipment. These fences can be widely used in urban road construction, building construction, accident sites and other places.

[0003] However, existing construction safety fences are bulky, making them difficult and time-consuming to move and store. Furthermore, they require bolts and other accessories for assembly, making the entire assembly and disassembly process cumbersome and inconvenient for practical use. Therefore, it is necessary to propose a protective device for construction projects to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for construction projects, which is convenient to store and transport, and easy to assemble and disassemble.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a protective device for construction engineering, comprising two protective main plates hinged to each other, with protective secondary plates slidably arranged in the inner cavities of both protective main plates. Each protective secondary plate has a limiting plug and an installation assembly for connecting the other protective secondary plate on one side extending outside the protective main plate. Each protective secondary plate has a connector at one end located within the inner cavity of the protective main plate. The installation assembly includes a connecting frame mounted on one protective secondary plate. A bidirectional lead screw and a guide rod are vertically arranged within the connecting frame. Two sliding blocks that are slidably adapted to the guide rod are arranged on the external threads of the bidirectional lead screw. Two mating blocks are installed on the other protective secondary plate. Insert rods inserted into the mating blocks are installed on opposite sides of the two sliding blocks. A linkage for controlling the rotation of the bidirectional lead screw is provided on the connecting frame.

[0006] By adopting the above technical solution, during transportation, the protective sub-plate is incorporated into the protective main plate and fixed by the limiting plug. The two protective main plates are then rotated and folded, which greatly reduces the volume of the entire protective device, making it easier for construction personnel to transport. After reaching the installation position, it is unfolded and the two protective sub-plates are joined together. By rotating the bidirectional screw through the linkage, the relative displacement of the two sliding blocks is controlled under the guidance and limiting of the guide rod, so that the end plug is inserted into the two docking blocks on the side of the other protective sub-plate, making the two protective sub-plates on the side installed stably. The entire installation process is very simple and convenient, making the device more convenient to use.

[0007] A further feature of this invention is that the linkage includes a worm gear rotatably mounted on a connecting frame, a worm wheel adapted to the worm gear is sleeved at the middle of the outer side of the bidirectional lead screw, and a handle is installed at one end of the worm gear extending to the outside of the connecting frame.

[0008] By adopting the above technical solution, the worm gear is rotated by holding the handle, which causes the worm wheel to rotate and drive the bidirectional lead screw to rotate, thereby achieving rapid docking of the two protective sub-plates.

[0009] A further feature of this invention is that the connecting member includes two vertical rods installed inside the protective main plate, and each of the two vertical rods is fitted with a sliding block and a first spring that abuts against the sliding block. The sliding block is provided with a rotating rod that is rotatably connected to the protective sub-plate.

[0010] By adopting the above technical solution, when the protective subplate slides outward, the rotating rod gradually turns to a vertical state, and the sliding block always slides on the vertical rod. The extension and retraction of the first spring makes its movement more convenient, so that the protective subplate will not detach from the protective main plate when it slides.

[0011] A further feature of this invention is that the limiting plug includes two movable blocks, one upper and one lower, slidably disposed on one side of the protective sub-plate. A second spring is installed on the opposite side of each of the two movable blocks, and a post is installed on the opposite side of each of the two movable blocks. Through holes adapted to the posts are provided on both the upper and lower sides of the protective main plate. A handle that is movably connected to the protective sub-plate is installed on the side of each movable block.

[0012] By adopting the above technical solution, the push-pull handle drives the movable block to compress the second spring, so that when the protective sub-plate is retracted into the protective main plate, the insert pin is inserted into the through hole of the protective main plate to fix the protective sub-plate.

[0013] A further feature of this invention is that magnetic blocks are installed on one side of the front of each of the two protective motherboards, and the front sides of the two magnetic blocks attract each other.

[0014] By adopting the above technical solution, when the two protective main boards are rotated, they are stacked together and held in place by magnetic blocks, reducing the overall size of the device and making it easier for construction personnel to move.

[0015] The beneficial effects of this utility model are:

[0016] 1. This utility model, by pushing the protective sub-plate into the protective main plate, pushing and pulling the handle, drives the movable block to squeeze the second spring, inserting the insertion post into the through hole of the protective main plate, storing and fixing the protective sub-plate, then rotating the two protective main plates to stack them together, and attracting them with magnetic blocks, can greatly reduce the overall size of the device, making it convenient for construction personnel to move and install.

[0017] 2. During installation, the entire device is unfolded and the bidirectional lead screw is rotated through the linkage. Under the guidance and limit of the guide rod, the relative displacement of the two sliding blocks is controlled, so that the end plug is inserted into the two mating blocks on the side of the other protective sub-plate, making the two protective sub-plates on the side installed stably. The entire installation process is very simple and convenient. Attached Figure Description

Protective auxiliary plates 2 are slidably disposed within the inner cavities of both protective main plates 1. Each auxiliary plate 2 has a limiting insert 3 and an installation assembly 4 connecting to the other auxiliary plate 2 on one side extending outside the protective main plate 1. A connector 5 is disposed at one end of each auxiliary plate 2 located within the inner cavity of the protective main plate 1. The installation assembly 4 includes a connecting frame 41 mounted on one auxiliary plate 2. A bidirectional lead screw 42 and a guide rod 43 are vertically disposed within the connecting frame 41. Two sliding blocks 44, which are slidably adapted to the guide rod 43, are disposed on the external threads of the bidirectional lead screw 42. Two mating blocks 45 are mounted on the other auxiliary plate 2. Insert rods 46, which are inserted into the mating blocks 45, are disposed on the opposite sides of the two sliding blocks 44. A linkage component for controlling the rotation of the bidirectional lead screw 42 is disposed on the connecting frame 41.

[0026] Furthermore, the linkage includes a worm gear 47 rotatably mounted on the connecting frame 41, a worm wheel 48 adapted to the worm gear 47 is sleeved at the middle of the outer side of the bidirectional lead screw 42, and a handle 49 is installed at one end of the worm gear 47 extending to the outside of the connecting frame 41.

[0027] Furthermore, the connector 5 includes two vertical rods 51 vertically installed inside the protective main plate 1. Each of the two vertical rods 51 is fitted with a sliding block 52 and a first spring 53 that abuts against the sliding block 52. The sliding block 52 is provided with a rotating rod 54 that is rotatably connected to the protective sub-plate 2.

[0028] Furthermore, the limiting plug 3 includes two movable blocks 31 that are slidably disposed on one side of the protective sub-plate 2.
