DETAILED DESCRIPTION

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] See also Figure 1-Figure 4 , an embodiment provided by the utility model:

[0021] An aluminum profile for making a small packaging box has the same cross-section at different positions along the length direction of the profile, including a panel 1, a U-shaped plate 2, an L-shaped plate 3 and a bent plate 4. The outer side surface of the U-shaped plate 2 is aligned with the left side surface of the panel 1 in the width direction and the opening is facing the panel 1 and is fixedly connected to the panel 1. The U-shaped plate 2 and the left end of the panel 1 form a left cavity 5, which is used to insert a second connecting block 10 so as to connect the side box block 11, and also plays a reinforcing role. The bent plate 4 is provided with a straight plate 401 and an inclined plate 402. The straight plate 401 is vertically fixedly connected to the panel 1. The outer side surface of the straight plate 401 is aligned with the right side surface of the panel 1 in the width direction. The L-shaped plate 3 is provided with a long plate 301 and a short plate 302 perpendicular to each other. The long plate 301 is perpendicular to the panel 1 and has no end. It is fixedly connected to the panel 1, the long plate 301 is located on the left side of the straight plate 401, and the short plate 302 is located on the left side above the straight plate 401 and is flush with the top surface of the U-shaped plate 2. The function of the short plate 302 is mainly to form a hinge spring working space under the short plate 302 when the aluminum profile is used to make a packaging box, so as to avoid damage to the interior of the packaging box due to the hinge spring when working. Secondly, it plays a supporting role when the upper box body 7 is in a closed state, so that the upper box body 7, the lower box body 8, and the side box block 11 form a sealed space and keep the packaging box neat and beautiful. The inclined plate 402 is fixedly connected to the upper end of the straight plate 401, and the straight plate 401, the L-shaped plate 3, and the right end of the panel 1 form a right cavity 6, which is used to insert the first connecting block 9 to connect the side box block 11, and also plays a reinforcing role.

[0022] The angle α between the inclined plate 402 and the panel 1 ranges from 35 to 45 degrees. The angle α is used to control the maximum opening angle of the upper box body 7. In this embodiment, the angle α is equal to 42.5 degrees, and the maximum opening angle of the upper box body 7 is 95 degrees.

[0023] Among them, a corrugated groove area 303 is fixedly provided on the side of the long board 301 facing the straight board 401, which matches the buckling structure of the hinge and is used for buckling and fixing the hinge.

[0024] A groove 304 is provided at the intersection of the short plate 302 and the inclined plate 402 for accommodating the hinge column of the hinge.

[0025] The panel 1, the U-shaped plate 2, the L-shaped plate 3 and the bent plate 4 are made of aluminum alloy and are integrally formed by melt casting and extrusion.

[0026] When making packaging boxes, Figure 3-Figure 4As shown, firstly, two sections of the aluminum profile of the same length are cut, which are used as the upper box body 7 and the lower box body 8 respectively, and two waist-shaped grooves are opened at the groove 304 and a slot hole connected to the waist-shaped groove is opened at the long plate 301 to install the hinge. The hinge adopts a spring-type hinge. The hinge column of the hinge (not shown in the figure) is placed at the groove 304. The two leaves of the hinge pass through the waist-shaped grooves of the upper box body 7 and the lower box body 8 respectively and are buckled with the corrugated groove area 303 to complete the hinging of the upper box body 7 and the lower box body 8. When the upper box body 7 is opened or closed, when the hinge spring is working, the hinge spring will protrude into the box body and pass through the slot hole and finally be located in the hinge spring working space below the short plate 302. It will not touch the interior during work and will not cause damage to the interior. The side box block 11 is a hollow rectangular aluminum alloy tube. The first connecting block 9 and the second connecting block 10 are both purchased L-shaped hollow plastic Materials, the shape of one end of the first connecting block 9 matches the right cavity 6, and the shape of the other end matches the inner cavity of the side box block 11, the shape of one end of the second connecting block 10 matches the left cavity 5, and the shape of the other end matches the inner cavity of the side box block 11, after the first connecting block 9 and the second connecting block 10 are fully inserted into the two ends of the side box block 11, respectively, and then the other ends of the first connecting block 9 and the second connecting block 10 are fully inserted into the right cavity 6 and the left cavity 5 at one end of the lower box body 8, respectively, so that the side box block 11 is connected to one end of the lower box body 8, and at the same time, due to the extrusion of the first connecting block 9 in the right cavity 6, the spring hinge is completely fixed on the corrugated groove area 303, so that the hinge of the upper box body 7 and the lower box body 8 is firm and reliable. Similarly, the connection between the side box block 11 and the other end of the lower box body 8 and the two ends of the upper box body 7 is completed, and finally velvet is pasted on the upper box body 7 and the lower box body 8 to complete the production of the packaging box.
