Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and more specifically, it relates to a protective device for reserved holes in building construction. Background Technology

[0002] In building construction, pre-reserved holes refer to openings made in the building structure before construction begins, according to design requirements. These holes are typically used for the later installation of building equipment, pipes, wires, cables, ventilation openings, drainage outlets, and other facilities, or for structural needs such as providing passageways for support points or cooling systems. If these pre-reserved holes are not sealed or protected in a timely manner, construction workers or materials can easily fall into them, leading to safety accidents.

[0003] Based on the above, the inventors have discovered the following problems: In the current construction hole protection devices, when workers need to enter some large holes, the hole protection devices are not easy to open and close, require frequent movement, are inconvenient for site construction, reduce construction convenience, and reduce work efficiency.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a protective device for reserved holes in building construction, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose and effect of this utility model's protective device for reserved holes in building construction are achieved by the following specific technical means: A protective device for pre-reserved holes in building construction includes a protective base with a through groove inside. A protective cover is movably installed on the protective base at the top of the through groove. An installation block is installed on one side of the protective cover, and a pin is movably installed on the installation block. An installation plate is installed on the top periphery of the protective base, and the installation plate has a slot. The pin engages with the slot. A pair of support plates are movably installed on both sides of the protective base at the installation plate, and a pair of rollers are installed at the bottom end of each support plate.

[0006] Furthermore, the pin is slidably connected to the mounting block.

[0007] Furthermore, the mounting block has a groove on the periphery of the pin, and a slider is installed on the pin at the bottom of the groove. A spring is installed on the top of the slider, and the top of the spring is connected to the top of the groove.

[0008] Furthermore, the spring is fitted around the periphery of the pin.

[0009] Furthermore, a pull ring is installed at the top of the pin on the outside of the mounting block.

[0010] Furthermore, a pair of threaded rods are screwed onto both sides of the mounting plate, the bottom ends of the pair of threaded rods extend to the bottom end of the mounting plate and connect with the surface of the support plate, and a limit rod is installed on the support plate, the top of the limit rod penetrating the mounting plate and extending to the outside.

[0011] Furthermore, one end of the protective cover has a protrusion that is hinged to the mounting plate via a rotating rod.

[0012] Compared with the prior art, the present invention has the following beneficial effects: The protective cover is placed around the hole by the protective base. Pulling the pin upwards disengages it from the slot, allowing the protective cover to rotate and expose the through slot, making it easy for construction workers to enter the hole. After the work is finished, rotating the protective cover again and engaging it with the slot with the pin secures it. This eliminates the need to frequently move the protective cover, improving work efficiency and providing convenience for construction.

[0013] The pull ring facilitates the pulling of the pin, the slider compresses the spring, and the pull ring is released. The spring returns the slider to its original position through its elastic force, which in turn pulls the pin to its original position, allowing the pin to engage with the slot. This makes it easy for construction workers to operate and provides convenience.

[0014] By rotating the threaded rod, the support plate can be lowered, causing the rollers to contact the ground and lifting the protective base. This facilitates the movement of the protective base, eliminating the need to repeatedly move it and saving physical effort. The limit rod is slidably connected to the mounting plate, limiting the lifting path of the support plate and allowing it to rise and fall vertically, thus improving its practicality.
