Example one

As shown in Figure 1 and Figure 2,

This kind of safety box for preventing children from opening includes:

The pulp outer box 1 and the pulp outer box 1 are rectangular in shape, one end of the pulp outer box 1 has an inner box inlet and outlet opening 10, and the pulp outer box 1 is made of pulp plant fiber materials. Environmentally friendly and biodegradable.

The two sides of the pulp outer box 1 are respectively buckled with holes 11; the buckling holes 11 are square holes.

The inner pulp box 2 is made of pulp plant fiber material. Environmentally friendly and biodegradable.

The inner pulp box 2 enters the outer pulp box 1 from the inner box inlet and outlet opening 10, and both sides of the pulp outer box 1 are respectively provided with a convex buckle 20 that is buckled in the buckle hole 11, and The wall thickness of the convex buckle 20 is equal to the wall thickness of the pulp inner box 2.

The wall thickness is equal to facilitate processing and manufacturing, and at the same time, a more beautiful inner box can be produced.

As shown in Figure 3,

The two convex buckles 20 deform toward each other under the action of external force to force the convex buckle 20 to escape from the buckle hole 11 and push out the pulp inner box 2. The convex buckle 20 is buckled in the buckle hole 11 to realize the pulp outer The mutual locking of the box and the pulp inner box can also prevent the infant from accidentally opening the pulp inner box and thereby accidentally ingesting the food or medicine in the pulp inner box.

The structure is optimized, and the snap holes 11 provided on one side of the pulp outer box 1 and the snap holes 11 provided on the other side of the pulp outer box 1 are distributed in front and rear positions;

The outer convex buckles 20 arranged on one side of the pulp outer box 1 and the outer convex buckles 20 arranged on the other side of the pulp outer box 1 are distributed in front and rear positions. When the pulp inner box 2 enters the pulp outer box 1 The convex buckle 20 described later is buckled in the buckle hole 11.

Dislocation distribution can form multiple blocking and opening effects, including the asymmetrical position of the left and right sides of the convex buckle 20 and the easy-to-enter and anti-pull-out convex buckle 20, and the pulp inner box Once pushed in to the end, the convex buckles on the left and right sides automatically buckle the outer pulp box, and the inner pulp box will be completely submerged in the outer box to prevent children from digging out with their fingers or biting out with their teeth.

Furthermore, because the convex buckles on the left and right sides are not in a straight line, they are specially set to have a longer distance, so that the baby cannot press the buckles at the same time when the palm is small, so it can prevent the baby from pulling out.

As shown in Figure 1, Figure 2 and Figure 4,

The convex buckle 20 is a convex buckle inclined inward from the opening of the pulp inner box 2 to the bottom thereof, and an inclined groove 21 is formed on the inner side of the convex buckle 20 and the inclined direction is the same as the inclination direction of the convex buckle 20 .

The design of the inclined groove can realize the release of the deformation pressure and the free rebound after release, and the inclined outer convex buckle 20 can facilitate the pressing inward to quickly extract the pulp inner box.

The upper end of the outer convex buckle 20 protrudes from the outer opening of the buckle hole 11, and the upper end of the inclined groove 21 communicates with the outside. This structure can achieve locking and avoid the phenomenon of free fall off. Secondly, the communication of the outside can realize the air communication between the inside and the outside, which can prevent the inside of the pulp inner box from being difficult to withdraw due to sealing.

Secondly, there is a gap between the inner top of the outer pulp box 1 and the upper open end surface of the inner pulp box 2. Similarly, the gap can also prevent the inner pulp from being difficult to withdraw from the inner box due to the sealing.

The second convex side portion 202 is at such an angle, which can facilitate the insertion of the inner pulp box into the outer pulp box, that is, the second convex side portion 202 serves as a guide during insertion.

The width of the convex side 201 gradually decreases from the upper opening of the inner pulp box 2 to the bottom, and the width of the second convex side 202 gradually decreases from the upper opening of the pulp inner box 2 to the bottom. The width of the structural design can facilitate the improvement of the structural strength of the convex buckle without losing the deformability of the convex buckle. In addition, the above-mentioned structure can not only achieve the self-locking effect, but also reduce The main function of reducing the contact area between the convex side 201 and the corresponding hole wall surface of the buckle hole is to facilitate the subsequent extraction of the pulp inner box.

The width of the second convex side portion 202 gradually decreases from the upper opening of the pulp inner box 2 to its bottom. The corresponding hole wall surface of the snap hole and the second convex side portion 202 form a line contact, which can facilitate the pulp inner box 2 Pull out the pulp shell.

That is, the deformation of the convex side 201 is the largest, and the convex side The deformation of the second side 202 is smaller than the deformation of the first side 201 of the convex side.

Secondly, the groove depth of the inclined groove 21 is designed to facilitate the insertion of the inner pulp box into the outer pulp box for quick assembly.

The outer surface of the inclined portion 203 is an arc-shaped concave surface, and the inner surface of the inclined portion 203 is an arc-shaped convex surface. This design can facilitate the pressing of the convex buckle 20, that is, prevent the inaccurate pressing position due to the absence of pressing points and fail to smoothly The pulp inner box is drawn out.

The inner surface of the convex side portion 201 and the inner surface of the inclined portion 203 form an included angle of less than 90°; the inner surface of the convex side portion 202 and the inner surface of the inclined portion 203 form an angle greater than 90° four.

As shown in Figure 5,

The angle design can facilitate the deformation, and at the same time, it can also facilitate the reset after the deformation.

A closed portion 12 is provided at one end of the outer pulp box 1 away from the inlet and outlet opening 10 of the inner box, and an inner box ejection hole 13 provided on the closed portion 12. The inner box ejection hole 13 is a semicircular hole, which can facilitate the pulp inner box.
