[0031] like Figure 1As shown in Figure 8, the utility model provides a full-paper carton lock, which includes a blocking plate 1 with a square structure and a square through hole in the middle, adhesive plates 3 arranged on both sides of the blocking plate 1, which are in a concave shape and connected to the blocking plate 1 through a folding plate 2, folding lock units 4 arranged on the adhesive plates 3 on both sides and placed in the concave surface of the adhesive plates 3, locking plates 6 arranged on the blocking plate 1, placed on the opposite sides of the square through hole, and in a right angle structure with the adhesive plates 3 on both sides on the plane, with locking grooves 5, and a support frame 7 with a square structure mounted on the locking plates 6 on both sides; the folding lock unit 4 includes a side support plate 8 connected to the adhesive plates 3, an inner locking plate 9 connected to the side support plate 8, an inner support plate 10 connected to the inner locking plate 9, and a lock / unlock plate 12 connected to the inner support plate 10 and with locking protrusions 11 on both sides. When the carton lock is folded, the pasting plate 3 is pasted on the blocking plate 1 by water-based glue, and the folding lock unit 4 is folded accordingly to form the entire carton lock, and the support frame 7 is folded into a square structure by pasting with water-based glue, and finally the support frame 7 is pasted on the locking plates 6 on both sides by water-based glue. When in use, the support frame 7 is partially placed in the first lock mounting hole 24 and the second lock mounting hole 27 of the outer box body 26 and the inner bottom support 28, and the side support plate 8 is made to conflict with the support frame 7 by squeezing the lock / unlock plate 12 inward, so that the support frame 7 blocks the movement of the side support plate 8, and at the same time, the side support plate 8 also plays a role in supporting the support frame 7 to a certain extent. The locking protrusions 11 on both sides of the unlocking plate 12 enter the locking grooves 5 of the locking plate 6, so that the locking / unlocking plate 12 moves along the groove shape of the locking groove 5, and then the inner locking plate 9 will continue to move inward. Under the action of the inner support plate 8, the inner locking plate 9 will flip outward and conflict with the inner bottom bracket 28. At this time, the two inner support plates 9 are in a planar structure, and the locking / unlocking plate 12 is also pushed to the corresponding position, so that the locking protrusions 11 are stuck in the locking grooves 5, that is, the locking of the outer box body 26 and the inner bottom bracket 28 is achieved. Unlocking is the reverse engineering of locking, that is, the folding lock unit 4 is pulled out by sliding the locking / unlocking plate 12 along the locking groove 5, that is, the unlocking of the outer box body 26 and the inner bottom bracket 28 is achieved. This kind of carton lock can be used repeatedly.

[0032] The locking groove 5 includes an oblique locking groove 13 and a vertical locking groove 14 connected to the oblique locking groove 13 at the top side. The oblique locking groove 13 is stepped. The locking groove 5 is designed to be divided into two sections in order to better lock the lock / unlock plate 12. The oblique locking groove 13 plays a guiding role, while the vertical locking groove 14 plays a role in finally locking the lock / unlock plate 12, so that the lock / unlock plate 12 will not be separated from the locking groove 5.

[0033] The blocking plate 1 is provided with a first avoidance groove 15 used in conjunction with the oblique locking groove 13. The adhesive plate 3 on one side is provided with a second avoidance groove 16 used in conjunction with the oblique locking groove 13. The first avoidance groove 15 and the second avoidance groove 16 are provided to facilitate the locking / unlocking plate 12 with the locking protrusion 11 to enter the locking groove 5.

[0034] The two sides of the connection between the folding plate 2 and the blocking plate 1 are respectively provided with a first avoidance slope 17 that is oblique and avoids each other; the two sides of the connection between the folding plate 2 and the side support plate 8 are respectively provided with a second avoidance slope 18 that is oblique and avoids each other; the two sides of the connection between the locking plate 6 and the blocking plate 1 are respectively provided with a third avoidance slope 19 that is oblique and avoids each other; the two sides of the connection between the side support plate 8 and the inner locking plate 9 are respectively provided with a fourth avoidance slope 20 that is oblique and avoids each other; the two sides of the connection between the inner locking plate 9 and the inner support plate 10 are respectively provided with a fifth avoidance slope 21 that is oblique and avoids each other; the two sides of the connection between the inner support plate 10 and the lock / unlock plate 12 are respectively provided with a sixth avoidance slope 22 that is oblique and avoids each other; the two sides of the connection between the pasting plate 3 and the side support plate 8 are respectively provided with a seventh avoidance slope 23 that is oblique and avoids each other. The avoidance slopes are set at each folding point to reduce the mutual stress and also make the lock of the folded carton more beautiful.

[0035] The angle between the first avoidance slope 17, the second avoidance slope 18, the third avoidance slope 19, the fourth avoidance slope 20, the fifth avoidance slope 21, the sixth avoidance slope 22 and the seventh avoidance slope 23 and the horizontal plane is 30°-60°; the angle between the first avoidance slope 17, the second avoidance slope 18, the third avoidance slope 19, the fourth avoidance slope 20, the fifth avoidance slope 21, the sixth avoidance slope 22 and the seventh avoidance slope 23 and the horizontal plane is 45°. The avoidance slopes on both sides of each folding part are in a complementary state of 90°, and different angles can be selected for complementation according to the states of different positions, and the optimal one is 45°, which is convenient for production and does not require production at different angles, so that production efficiency is improved.

[0036] The blocking plate 1, the folding plate 2, the pasting plate 3, the folding lock unit 4, the locking plate 6 and the supporting frame 7 are all made of corrugated cardboard material. The corrugated cardboard material is green and environmentally friendly, can be reused many times, and can also be recycled for secondary processing without wasting resources.

[0037] like Fig. 9As shown in Figure 15, a carton includes the all-paper carton lock, and the carton also includes an outer box body 26 with first lock mounting holes 24 at both ends of the bottom side of two opposite front faces, and hand holes 25 at the top ends of two opposite side faces, and an inner bottom support 28 arranged in the outer box body 26 and with second lock mounting holes 27 at the bottom of two opposite sides, and opposite to the first lock mounting holes 24. This type of carton separates the inner bottom support 28 from the outer box body 26 and is suitable for packaging heavy products. When in use, the heavy products are placed in the inner bottom support 28, and the outer box body 26 is put over the heavy products and the inner bottom support 28. The carton lock is installed on the outer box body 26 and the inner bottom support 28 through the first lock mounting hole 24 on the outer box body 26 and the second lock mounting hole 27 on the inner bottom support 28. The outer box body 26 and the inner bottom support 28 are further locked together through the folding lock unit 4, that is, the locking connection between the outer box body 26 and the inner bottom support 28 is realized. The buckle hole 25 is set on the outer box body 26 to facilitate the movement of the carton and the heavy products inside.

[0038] This all-paper carton has a firm lock and is relatively simple to assemble and disassemble. It is easy to operate and can cover the holes on the package to prevent dust. It is made of corrugated cardboard, which is green and environmentally friendly. It is produced using white latex, which is also an environmentally friendly material. The size of the lock support frame, folding lock unit and locking plate, as well as the material of the cardboard can be adjusted to match the load-bearing requirements and the thickness of the outer box. The lock can clamp the two layers of cardboard of the outer box and the inner bottom support as needed to prevent the outer box from bulging and the lock from breaking free.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
