[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-5 This utility model provides an adjustable protective device for covering a reserved horizontal opening, including a right-angle steel pipe sleeve 1, a fastening screw 2, a telescopic steel pipe 3, and a fixed support 4.

[0025] Four right-angle steel pipe sleeves 1 are provided, and the four right-angle steel pipe sleeves 1 are connected in sequence by telescopic steel pipes 3. There are four telescopic steel pipes 3. The two ends of the inner side of the right-angle steel pipe sleeve 1 are provided with fastening screws 2, and the two ends of the inner side of the right-angle steel pipe sleeve 1 are fitted with telescopic steel pipes 3. The top of the telescopic steel pipes 3 is welded with a fixing support 4 for limiting and fixing the cover plate of the external opening. The fixing support 4 is formed by welding two angle steels. The inner side of the fixing support 4 is provided with an L-shaped groove 401 for limiting and fixing the cover plate. The cover plate is placed on the inner transverse end surface of the L-shaped groove 401. The outer side of the fixing support 4 protrudes 20mm from the right-angle steel pipe sleeve 1.

[0026] This utility model uses components such as a right-angle steel pipe sleeve 1, fastening screws 2, telescopic steel pipe 3, fixed support 4, and L-shaped groove 401 to work together to limit and fix the cover plate placed on the horizontal opening, so as to prevent the cover plate placed on the horizontal opening from shifting; at the same time, it also improves the safety of people on the lower level inside the opening and prevents people outside from falling into the opening.

[0027] In summary, this device not only achieves simple operation and convenient installation, saving time and labor, but also can be reused multiple times, saving construction costs. It has achieved tool-like and standardized functionality, and has significant social and economic benefits.

[0028] The right-angle steel pipe sleeve 1 has threaded holes 101 at both ends on its inner side. The fastening screw 2 includes a nut and a screw rod, with the screw rod fixedly connected to one end of the nut. The thread of the fastening screw 2 passes through the threaded hole 101 inside the right-angle steel pipe sleeve 1, and one end contacts the telescopic steel pipe 3.

[0029] By pinching the nut on the fastening screw 2 with your hand, you can rotate it to loosen the screw rod so that it can disengage from the threaded hole 101 on the right-angle steel pipe sleeve 1. Then, you can move the right-angle steel pipe sleeve 1 left and right or back and forth to adjust the length and width of the telescopic steel pipe 3 placed inside it, so as to be suitable for horizontal openings of different sizes. This design of the present invention is not only simple to operate and easy to install, saving time and labor, but also can be reused multiple times, thus improving its applicability.

[0030] After adjustment, take the fastening screw 2 and tighten the screw thread through the threaded hole 101 to the adjusted telescopic steel pipe 3 inside the right-angle steel pipe sleeve 1 so that the screw can contact and fix the telescopic steel pipe 3. Finally, take the adjusted cover plate and place it into the L-shaped groove 401 set inside the fixed support 4 so as to cover the reserved horizontal opening.

[0031] In summary, by installing adjustable protective devices that are tightly fixed to the main structure, the protection of the horizontal opening is ensured to be safe, stable, and secure.

[0032] Right-angle steel pipe sleeve 1 is made of 8 sections of 200mm long, 50×50×5mm square steel pipes, and four right-angle steel pipe sleeves 1 are welded to serve as the four corners of the fixing device.

[0033] The telescopic steel pipe 3 is made of four 500mm long square steel pipes of 42×42×4mm; these are connected in sequence with the right-angle steel pipe sleeve 1 to form an adjustable telescopic steel pipe 3.

[0034] For the fixed support 4, eight 200mm long, 40×4mm angle steel pieces are selected and welded sequentially to the top of the right-angle steel pipe sleeve 1.

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