A double-locking color box structure to prevent accidental opening

Abstract

This utility model discloses a double-locking color box structure to prevent accidental opening, including a box body, a lid hinged to the top of the box body, and hinge seats fixedly provided on both sides of the lid. Each of the two hinge seats has a limiting buckle hinged to its surface. This double-locking color box structure allows the lid to be initially positioned on the box body by engaging with two locking blocks. Then, the two locking blocks move downwards under the action of two telescopic springs, engaging with two limiting grooves to further limit the two limiting buckles, thus preventing the lid from falling off and causing the contents of the box to spill out. By sliding two sliders upwards, the two limiting blocks retract into two placement grooves, separating them from the two limiting grooves and no longer limiting the two limiting buckles, thus facilitating the removal of the two limiting buckles and the disassembly of the lid.

[0009] Preferably, a first reinforcing ring is fixedly provided at the bottom of the inner side of the box, a plurality of first reinforcing rods are fixedly provided on the inner side of the first reinforcing ring, and a plurality of second reinforcing rods are fixedly provided at the top of the first reinforcing ring. The plurality of first reinforcing rods and the plurality of second reinforcing rods are all fixedly connected to the box body. The structural strength of the box body can be improved by the cooperation of the first reinforcing ring, the plurality of first reinforcing rods and the plurality of second reinforcing rods.

[0010] Preferably, a second reinforcing ring is fixedly provided at the top of the inner side of the cover body, a plurality of first reinforcing ribs are fixedly provided on the inner side of the second reinforcing ring, and a plurality of second reinforcing ribs are fixedly provided at the bottom end of the second reinforcing ring. The plurality of first reinforcing ribs and the plurality of second reinforcing ribs are all fixedly connected to the cover body. The structural strength of the cover body can be improved by the combination of the second reinforcing ring, the plurality of first reinforcing ribs and the plurality of second reinforcing ribs.

[0011] Preferably, an auxiliary handle is fixedly provided on the front of the cover, which facilitates opening the cover.

[0012] Preferably, both the box body and the lid body include a base layer, the surface of which is provided with a waterproof layer, and the surface of which is provided with a decorative coating. The waterproof layer can improve the waterproof performance of the color box.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The lid is initially positioned on the box by engaging with two locking blocks using two limiting buckles. Then, the two limiting blocks move downwards under the action of two telescopic springs, engaging with two limiting grooves to further restrict the lid and prevent it from falling off and causing items inside the box to spill out. By sliding the two sliders upwards, the two limiting blocks retract into the two placement grooves, separating them from the limiting grooves and no longer restricting the two limiting buckles. This allows the two limiting buckles to be removed, facilitating the disassembly of the lid. Attached Figure Description

[0021] Please see Figure 1-4 This utility model provides a double-locking color box structure to prevent accidental opening, including a box body 1, a cover 2 hinged to the top of the box body 1, hinge seats 3 fixedly provided on both sides of the cover 2, limit buckles 4 hinged to the surface of each of the two hinge seats 3, and through holes 12 opened in the middle of each of the two limit buckles 4, locking blocks 5 fixedly provided on the top of both sides of the box body 1, mounting grooves 6 opened at the bottom of each of the two locking blocks 5, telescopic springs 7 fixedly provided on the top of the inner side of each of the two mounting grooves 6, and limit blocks 8 fixedly connected to the bottom of each of the two telescopic springs 7, and limit grooves 13 opened at the bottom of the inner side of each of the two through holes 12, the two limit blocks 8 respectively engaging with the two limit grooves 13, and the two through holes 12 respectively engaging with the two limit blocks 8. Each locking block 5 is correspondingly set, and the two limiting buckles 4 respectively engage with the two locking blocks 5 to initially limit the cover 2 on the box body 1. Then, the two limiting blocks 8 move downward under the action of the two telescopic springs 7, so that they engage with the two limiting grooves 13, thereby limiting the two limiting buckles 4, which facilitates further limiting of the cover 2 and can prevent the cover 2 from falling off and causing the items in the box body 1 to be thrown out. By sliding the two sliders 10 upward, the two limiting blocks 8 retract into the two placement grooves 6, so that they separate from the two limiting grooves 13 and no longer limit the two limiting buckles 4, thus making it easy to remove the two limiting buckles 4 and thus making it easy to disassemble the cover 2.

[0022] The bottom ends of the two limiting blocks 8 are provided with auxiliary inclined grooves 9, and the sides of the two limiting blocks 8 are fixedly connected with sliders 10. The sides of the inner walls of the two placement grooves 6 are provided with sliding grooves 11. The two sliders 10 are slidably connected to the two sliding grooves 11 respectively. The bottom of the inner side of the box body 1 is fixedly provided with a first reinforcing ring 14. The inner side of the first reinforcing ring 14 is fixedly provided with several first reinforcing rods 15. The top of the first reinforcing ring 14 is fixedly provided with several second reinforcing rods 16. The several first reinforcing rods 15 and the several second reinforcing rods 16 are all fixedly connected to the box body 1.

[0023] In use, the auxiliary inclined groove 9 facilitates the retraction of the two limiting blocks 8 into the two placement grooves 6 when they are squeezed. By sliding the two sliders 10 upward, the two limiting blocks 8 are retracted into the two placement grooves 6, separating them from the two limiting grooves 13 and no longer limiting the two limiting buckles 4. The structural strength of the box body 1 can be improved by the cooperation of the first reinforcing ring 14, several first reinforcing rods 15 and several second reinforcing rods 16.

[0024] A second reinforcing ring 17 is fixedly installed on the top of the inner side of the cover 2. Several first reinforcing ribs 18 are fixedly installed on the inner side of the second reinforcing ring 17. Several second reinforcing ribs 19 are fixedly installed at the bottom of the second reinforcing ring 17. Several first reinforcing ribs 18 and several second reinforcing ribs 19 are fixedly connected to the cover 2. An auxiliary handle 20 is fixedly installed on the front of the cover 2. Both the box body 1 and the cover 2 include a base layer 101. A waterproof layer 102 is provided on the surface of the base layer 101. A decorative coating 103 is provided on the surface of the waterproof layer 102.

[0025] In use, the structural strength of the cover 2 can be improved by the combination of the second reinforcing ring 17, several first reinforcing ribs 18 and several second reinforcing ribs 19, the cover 2 can be opened easily by the auxiliary handle 20, and the waterproof performance of the color box can be improved by the waterproof layer 102.

[0026] In this embodiment, the lid 2 is initially positioned on the box 1 by engaging with the two locking blocks 5 using the two limiting buckles 4. Then, the two limiting blocks 8 move downwards under the action of the two telescopic springs 7, engaging with the two limiting grooves 13, thereby further limiting the lid 2 and preventing it from falling off and causing the contents of the box 1 to spill out. When it is necessary to open the lid 2, the two sliders 10 are slid upwards to open the lid. The limiting block 8 retracts into the two placement grooves 6, separating it from the two limiting grooves 13, thus no longer limiting the two limiting buckles 4, making it easier to remove the two limiting buckles 4 and thus facilitating the disassembly of the cover 2. The structural strength of the box 1 is improved by the cooperation of the first reinforcing ring 14, several first reinforcing rods 15 and several second reinforcing rods 16, and the structural strength of the cover 2 is improved by the cooperation of the second reinforcing ring 17, several first reinforcing ribs 18 and several second reinforcing ribs 19.
