1. First embodiment of the rectangular frame 1: the upper side rod 9 of the frame, the bottom side rod 12 (as an implementation mode of the limit edge 49 shown in figure 2), the left side rod and the right side rod are welded into a square frame by adopting square pipes; the middle part adopts pipe and square pipe to set up two horizontal bracing pieces (first middle horizontal pole 14, second middle horizontal pole 15) both ends and left and right side pole 11 welding. The left and right side rods are welded with the upper side rod 9 and the bottom side rod 12 by beveling 45-degree notches, and the attached drawing 3 is shown in the figure.

Embodiment two of the frame: the upper side rod 9, the left side rod and the right side rod of the frame are square tubes, and the bottom frame (the bottom side rod 12) is welded into a square frame by adopting concave groove profile steel (as an implementation mode of a matching groove 48, shown in figures 2.1 and 2.2); the middle part adopts pipe and square pipe to set up two horizontal bracing pieces (first middle horizontal pole 14, second middle horizontal pole 15) both ends and left and right side pole 11 welding. The left and right side rods are welded with the corners of the upper side rod 9 by beveling 45-degree notches; the left and right side rods 11 and the bottom side rod 12 are spliced at two ends of the concave groove section steel, the plate surfaces at two ends of the concave groove section steel are provided with rectangular notches, and the rectangular notches are spliced and welded with the end parts of the left and right side rods 11 and the square tubes, and the attached drawing 3.1 is shown in the figure.

The frame adopts square pipe and angle steel, concave type channel-section steel (can form or select for use the channel-section steel with steel sheet or other shaped steel concatenations), pipe welding, and square pipe, angle steel and pipe have better intensity, rigidity and stability in shaped steel, make the frame more firm.

The middle part of the frame is provided with two transverse supporting rods, and the first middle cross rod 14 adopts a round pipe as a fixed shaft connected with a first hinge at the first end of the upper bracket 3, and also plays a role in reinforcing and stabilizing the frame, so that the frame is not deformed by external force; the second middle cross rod 15 adopts a square tube, plays a role in reinforcing and stabilizing the frame, so that the frame is not deformed by external force, and is shown in the attached drawings 3 and 3.1. Meanwhile, each rod piece of the frame and each rod piece of the second middle cross rod 15 are welded with the punched hole plate 2 in a spot welding mode, so that the punched hole plate 2, each rod piece of the frame and each rod piece of the second middle cross rod 15 inside the frame form a whole, each rod piece of the frame and each rod piece of the second middle cross rod 15 inside the frame play a role in reinforcing the punched hole plate 2, the punched hole plate 2 plays a role in reinforcing and stabilizing the frame, the frame and the punched hole plate 2 form a whole, and the rigidity, the strength and the stability of the whole safety protection folding type enclosure are improved due to the common effect.

2. Punching the pore plate 2: the air passing holes 19 of the punching hole plate 2 are arranged by adopting round holes and shutters; the size, the length, the opening width, the pressed concave-convex degree of the shutter, the pressed radian and the pressed angle of the shutter are determined through calculation and experiments; the size parameter-stability (strength, rigidity) change curve, the size parameter-overfire rate change curve and the intersection point of the two change curves determine the size parameter of the control change curve as the optimal parameter. The diameter of the round hole is 8-10mm, and the center distance is 20 mm; the optimal size parameters of the round holes and the shutters not only ensure the air passing amount, but also ensure the strength, rigidity and stability of the surfaces; see figure 5 for details.

A circle of round holes (edge holes 20) with the diameter of 8-10mm are uniformly distributed at the position 35mm away from the edge of the periphery of the punching orifice plate 2; when the enclosure is used, a plurality of enclosures are arranged, every two adjacent enclosures can be bound by iron wires 21 through edge vertical holes to be reinforced, so that the plurality of enclosures form a whole, and the stability of the whole is improved; the lower edge hole 20 plays a role in fixing and reinforcing with the ground; the round hole at upper portion edge is used for installing automatic spray device's nozzle, encloses the fender and can self-cleaning enclose the fender face in the use, guarantees that the face is clean and tidy, can also fix warning light and warning mark, gives and is close to personnel with the warning effect.

The round holes are not easy to wear and long in service life, the effective area of the round holes is the largest under the condition that the perimeters of the openings are the same, the effective air passing area is large, and the board surface is not easy to deform. The round hole has no internal and external corners, and is not easy to tear after being perforated, thereby not only ensuring the strength and stability of the board surface, but also improving the air passing rate to the maximum extent.

The concave-convex direction of the shutter blocks the external sight, and the ventilation and the blocking of the external sight to the sight in the enclosure

In the aspect of ventilation, the shutter is manufactured by a stamping process, and the shutter is designed in a concave-convex streamline manner and made of a hard material, so that the function of improving the aesthetic feeling of the product shape is realized, airflow can smoothly pass through the shutter, and the wind resistance of the surface of the enclosure is reduced; the concave-convex direction design of the louver ensures the concealment and safety of the construction in the enclosure; in addition, the sound insulation and dust insulation functions can be achieved. The stamping process makes the louver smooth and flat without pricking hands. The rigidity is the capacity of the object to resist deformation, and the larger the rigidity is, the smaller the deformation is when the object is stressed. When the enclosure is impacted by strong wind and heavy objects, if the flat thin plate is adopted, the thin plate can be certainly deformed and protruded by external force, the appearance is very influenced, concave and convex shutters are punched on the flat thin plate, the rigidity of the thin plate is also increased due to the shape change of the flat thin plate, the deformation effect after the external force is applied is obviously reduced, and the appearance is not influenced.

Enclose the fender face and pass through the unsmooth shutter of punching press preparation, have following advantage after changing the face shape: (1) a thinner plate can be used for replacing a thicker flat plate, and meanwhile, the box body can be kept not to deform, so that the production cost is greatly saved; (2) after the enclosure is impacted by strong wind and heavy objects, the enclosure can still bear the impact of the strong wind and the heavy objects without deformation; (3) during welding, a common flat plate can deform due to high temperature, so that the flat plate becomes uneven and the integral attractiveness is affected; but adopt the punching press technology at the unsmooth streamlined of panel preparation shutter, make the face just can be with the strain dispersion when welding, make panel can keep original form unchangeable, can keep elegant appearance.

The air passing holes 19 of the punching hole plate 2 are combined by round holes and shutters, so that the respective advantages of the round holes and the shutters are comprehensively highlighted; the optimal air-passing rate greatly reduces the wind resistance of the safety protection enclosure, thereby reducing the weight pressed by the support and the ground, and reducing the cost for fixing the safety protection enclosure. The shutter is formed by stamping a galvanized plate, and the rigidity, the strength and the stability of the stamped hole plate 2 can be enhanced by the concave-convex shape of the stamped shutter. Because the bottom of the punching orifice plate 2 is easy to deform due to impact, better strength and stability are needed, and in order to enhance the stability of the punching orifice plate 2 and prevent deformation, most of the shutters are arranged at the lower part to increase the rigidity, the strength and the overall stability of the lower part, prevent distortion and deformation, play a role in reinforcing ribs, ensure the air passing rate, strengthen the overall rigidity and the stability, save frame materials, reduce the support rods and the rod pieces of the frame, and achieve the purpose of saving cost. Because the air passing rate of the round holes is better than that of the shutter, when the punched hole plate 2 is subjected to wind resistance, the resistance of the upper part is large, and therefore the round holes with good air passing rate are arranged on the upper part with large wind resistance. The bottom of the punching hole plate 2 is small in wind resistance, the required strength and rigidity are high, zebra stripes and zebra stripe indication arrows need to be printed on the bottom, and therefore circular holes and shutters are not arranged on the bottom. The best shutter structural arrangement greatly enhances the strength of the punched hole plate 2, thereby reducing the structural layout of the frame, greatly reducing the structural members of the frame under the condition that the safety protection enclosure reaches the stability of the rigidity of the designed strength, and saving the cost of manufacturing and materials.
