Description

Technical Field

[0001] This utility model belongs to the field of safety production technology, specifically relating to a foldable safety cover device for protecting openings in building construction. Background Technology

[0002] In recent years, the country has attached increasing importance to safety management in production. Construction openings are a major source of danger, and countless safety accidents are caused by inadequate opening protection every year. Therefore, during construction, edge and opening protection is an important indicator of a safe and civilized construction site and a key focus of safety supervision and inspection. The "Technical Specification for Safety of High-Altitude Operations in Building Construction" issued by the General Office of the Ministry of Housing and Urban-Rural Development has clear regulations on opening protection. Currently, the opening protection devices installed on construction sites are generally made of ordinary formwork constructed from wooden boards and timber. However, the safety of such protective formwork is far from meeting the requirements, and it has the following problems: it is merely decorative and serves to pass inspections, without any actual protective significance, and it easily leads to accidents.

[0003] Currently, existing safety covers for openings are usually made of wood or metal. Wooden covers are difficult to reuse, have low strength, and are prone to causing safety hazards and endangering the personal safety of construction workers. While customized steel protective devices are stronger, metal covers require a lot of space during transportation, have high production costs, and are not very practical. Utility Model Content

[0004] To address the problems mentioned in the background art, this utility model provides a foldable safety cover device for protecting construction openings. It solves the problems that wooden covers are difficult to reuse, have low strength, are prone to causing safety hazards and endangering the personal safety of construction workers, and that metal covers require a lot of space during transportation, have high production costs, and are not very practical.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable safety cover device for protecting construction openings, comprising a base plate, a second damping shaft connected to one side of the surface of the base plate, a second safety cover connected to one side of the surface of the second damping shaft, a first damping shaft connected to one side of the surface of the second safety cover, a first safety cover connected to one side of the surface of the first damping shaft, and an insertion groove provided on one side of the surface of the base plate, wherein the surface of the insertion groove engages with one side of the surface of the first safety cover.

[0006] Preferably, left limiting grooves are provided on both sides of the lower surface of the first safety cover.

[0007] Preferably, the lower surface of the second safety cover is provided with right limiting grooves on both sides, and the positions of the right limiting grooves and the left limiting grooves correspond to each other.

[0008] Preferably, the surface of the base plate is provided with four sets of support blocks, the surface of the support blocks is fixedly connected to limit blocks, and the surface of the limit blocks is slidably connected to the surface of the left limit groove and the right limit groove, respectively.

[0009] Preferably, both sides of the base plate surface are provided with lower limit grooves, and the bottom of the support block is slidably connected to the surface of the lower limit grooves.

[0010] Preferably, the upper surface of the first safety cover is provided with multiple sets of first anti-slip grooves, and the upper surface of the second safety cover is provided with multiple sets of second anti-slip grooves.

[0011] Preferably, the base plate, the first damping shaft, the first safety cover, the second damping shaft, and the second safety cover form a triangular positional relationship, and the triangle has stability.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The support block, first rotating shaft, second rotating shaft, first safety cover plate, second safety cover plate, and base plate work together to form an isosceles triangle structure. The support plate supports the first and second safety cover plates, increasing the strength of the safety cover device. The base plate also provides double protection, preventing safety hazards caused by low cover plate strength and better protecting the personal safety of workers. The first and second rotating shafts work together to allow the support block to be removed and the first, second, and base plates folded when not in use, saving space, reducing production costs, and increasing practicality.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a foldable safety cover device for protecting construction openings, comprising a base plate 1, a second damping shaft 9 connected to one side of the surface of the base plate 1, a second safety cover 3 connected to one side of the surface of the second damping shaft 9, a first damping shaft 7 connected to one side of the surface of the second safety cover 3, a first safety cover 2 connected to one side of the surface of the first damping shaft 7, and an insertion groove 10 provided on one side of the surface of the base plate 1, wherein the surface of the insertion groove 10 is engaged with one side of the surface of the first safety cover 2.

[0023] In this embodiment, the hinged design of the first damping shaft 7 and the second damping shaft 9 enables the flexible folding and unfolding of the first safety cover 2 and the second safety cover 3. The first damping shaft 7 and the second damping shaft 9 can fix the angle between the base plate 1 and the first safety cover 2 and the second safety cover 3, preventing accidental closure or shaking during construction and ensuring operational safety and stability.

[0024] In this embodiment, multiple sets of first anti-slip grooves 4 and second anti-slip grooves 8 cooperate with each other, which can significantly increase the friction when workers walk on them, effectively preventing construction workers or tools from slipping and avoiding slipping that could endanger the personal safety of construction workers.

[0025] In this embodiment, the left limiting groove 11 and the right limiting groove 12 restrict the position of the support block 6, thereby improving the stability of the support block 6. At the same time, the support block 6 can support the angle between the first safety cover plate 2 and the second safety cover plate 3 and the base plate 1, reducing the pressure at the angle between the first safety cover plate 2 and the second safety cover plate 3 and the base plate 1. This allows the device to withstand more weight and also prevents the first safety cover plate 2 and the second safety cover plate 3 from deforming during use, thus improving the service life of the device.

[0026] In this embodiment, the base plate 1, the first safety cover plate 2, and the second safety cover plate 3 form a stable triangular frame structure through the first damping shaft 7 and the second damping shaft 9. By utilizing the principle of triangular mechanical stability, the compressive strength, bending strength, and deformation resistance are significantly improved. The triangular structure disperses the load stress and prevents the cover plate from collapsing locally due to concentrated loads. Under dynamic impact, the triangular frame can quickly transmit and buffer the impact force, reducing the risk of structural damage.

[0027] In this embodiment, the sliding connection design between the left limiting groove 11, the right limiting groove 12 and the limiting block 13 ensures that the cover plate can be accurately aligned when it is unfolded, prevents lateral displacement and improves the stability when supported.

[0028] The working principle and usage process of this utility model are as follows: After the utility model is installed, the device is placed over the opening that needs protection. Then, the second safety cover 3 is rotated to the corresponding angle by the second damping shaft 9. Next, the angle of the first safety cover 2 is adjusted by the first damping shaft 7. One end of the first safety cover 2 is inserted into the insertion groove 10. Then, the bottom of the four sets of support blocks 6 is inserted into the surface of the lower limit groove 5. The support blocks 6 are pushed forward so that they move forward along the lower limit groove 5 until the angle between the support blocks 6 and the base plate 1, the first safety cover 2 and the second safety cover 3 are completely fitted. The opening is protected by the triangular structure. After the construction is completed, the device can be folded. The four sets of support blocks 6 are removed. Then, the first safety cover 2 is pulled backward so that it is detached from the inside of the insertion groove 10. The first safety cover 2 and the second safety cover 3 are pressed down until the lower surface of the first safety cover 2 and the second safety cover 3 are fitted with the upper surface of the base plate 1. The device can then be folded.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
