Description

Technical Field

[0001] The utility model relates to the technical field of foldable safety boxes, in particular to a portable foldable safety box. Background Art

[0002] A safety box is a device used to prevent the storage of valuables. It can protect the items from damage or external force. This type of box is usually used in industry to store fragile items or valuable instruments and equipment, and the quality and workmanship of the box are very high. Industrial-grade safety boxes need to have multiple characteristics, among which pressure resistance and impact resistance are indispensable to ensure that precision instruments can maintain their normal use state in the safety box and realize their value. In order to facilitate carrying and storage, portable foldable safety boxes are applied. Existing portable foldable safety boxes are mostly hinged folding plates, which are folded or unfolded to achieve the folding and portability of the safety box. When the folding plates of traditional portable foldable safety boxes are unfolded, they are fixed by buckles, and the fixing effect is poor and the impact resistance is low. When a bump occurs, the box body is prone to collapse, which is not conducive to protecting the items in the box. For this reason, we propose a portable foldable safety box. Utility Model Content

[0008] Furthermore, the folding storage mechanism also includes an arc-shaped opening and a protruding column. The arc-shaped openings are opened in the middle of the opposite outer sides of the upper folding plate and the lower folding plate, and the protruding columns are arranged at the lower ends of the opposite outer sides of the fixing rod. The outer surfaces of the protruding columns are installed in cooperation with the inner sides of the laterally adjacent arc-shaped openings to facilitate the rotation of the fixing rod.

[0013] Compared with the prior art, the utility model has the following advantages:

[0014] 1. Lift the installation frame upwards, slowly unfold the upper folding plate and the lower folding plate, deflect the upper folding plate outward 90 degrees with hinge 3 as the center, and deflect the lower folding plate outward 90 degrees with hinge 1 as the center, until the upper folding plate and the lower folding plate are flat, open the box cover, deflect the side plate outward 90 degrees with hinge 5 as the center, until the upper end protrusion of the side plate is engaged with the inner wall of the card slot, at this time, the safety box is initially unfolded, in order to increase the strength of the safety box structure, hard support is required, release the limit first, and the safety box can be quickly unfolded and closed, and the small size is convenient for carrying.

[0015] 2. Lift the limit plate to the right, and move the slider to the right synchronously. The tension spring is expanded under force. At this time, the limit plate loses its limit. Deflect the limit plate 90 degrees, and the limiting effect disappears. Move the raised column downward 90 degrees through the arc-shaped opening, and the fixed rod is also deflected downward 90 degrees. The torsion spring is elastically deformed under force until the lower end of the fixed rod contacts the locking head. As the fixed rod continues to deflect, the locking head is forced to move downward, driving the locking block to move downward synchronously. The spring is compressed under force until the fixed rod passes the upper end of the locking head and reaches the appropriate position. The upper end of the stop head is not under force, and the spring brings the locking block and the locking head back to their original position. Then the limit plate is pulled to the right again, and the limit plate is rotated 90 degrees to return the limit plate to its original position. Then let go, and the tension spring shrinks without force, so that the limit plate is close to the inner wall of the avoidance opening to form a limit. At this time, the structural strength of the safety box reaches the highest. After unfolding, the upper and lower folding plates are supported and fixed by hardware, which maintains the foldable performance while improving the impact resistance. A limit device is also provided to prevent the box from collapsing due to bumps and loosening, which can effectively protect the items in the box. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The working principle of a portable foldable safety box provided by the utility model is as follows: when using the portable foldable safety box, the installation frame 3 is lifted upward, the upper foldable plate 5 and the lower foldable plate 6 are slowly unfolded, the upper foldable plate 5 is deflected outward by 90 degrees with the hinge 3 as the center of the circle, and the lower foldable plate 6 is deflected outward by 90 degrees with the lower hinge 1 as the center of the circle, until the upper foldable plate 5 and the lower foldable plate 6 are flat, the box cover 4 is opened, and the side plate 2 is deflected outward by 90 degrees with the hinge 5 as the center of the circle, until the upper foldable plate 5 and the lower foldable plate 6 are flat, The end protrusion is engaged with the inner wall of the card slot 8. At this time, the safety box is initially unfolded. In order to increase the strength of the safety box structure, hard support is required. First, the limit is released, and the limit piece 784 is lifted to the right, and the slider 782 moves to the right synchronously. The tension spring 783 is expanded under force. At this time, the limit piece 784 loses its restriction, and the limit piece 784 is deflected ninety degrees. The limiting effect disappears, and the protruding column 76 is pushed downward ninety degrees through the arc-shaped opening 75, and the fixing rod 74 is also deflected ninety degrees downward. When the locking cam 771 is in the closed position, the torsion spring 773 is elastically deformed under the force until the lower end of the fixing rod 74 contacts the locking head 772. As the fixing rod 74 continues to deflect, the locking head 772 is forced to move downward, driving the locking block 771 to move downward synchronously. The spring 775 is compressed under the force until the fixing rod 74 passes the upper end of the locking head 772 and reaches the appropriate position. The upper end of the locking head 772 is not forced, and the spring 775 brings the locking block 771 and the locking head 772 back to their original positions, and then the limit is pulled right again. The limit piece 784 is rotated 90 degrees to return the limit piece 784 to its original position, and then the tension spring 783 is contracted without force, so that the limit piece 784 is close to the inner wall of the avoidance opening 9 to form a limit. At this time, the structural strength of the safety box reaches the highest level. After unfolding, the upper and lower folding plates are supported and fixed by hardware, which maintains the foldable performance while improving the impact resistance. A limit device is also provided to prevent the box from collapsing due to bumps and loosening, which can effectively protect the items in the box.
