Description

Technical Field

[0001] The utility model relates to the technical field of corrugated paper boxes, in particular to a corrugated paper box with hidden handles. Background Art

[0002] Corrugated paper is a plate-like material made by gluing noodle paper and corrugated paper formed by corrugating rollers. Corrugated paper has the advantages of low cost, light weight, easy processing, high strength, and convenient storage and transportation. Corrugated cardboard can be made into corrugated boxes through die-cutting, creasing, nailing or gluing. Corrugated boxes are the most widely used packaging products and their usage has always been the highest among various packaging products.

[0003] After searching the Chinese patent with publication number CN218617700U, a corrugated cardboard box with a hidden extraction mechanism is disclosed. By setting a clamping block, a mounting seat and a handle, the handle is rotated and installed on the outside of the bottom end of the mounting seat during use of the cardboard box, and then the mounting seat is installed on the inner side of one end of the corrugated cardboard box body through a limit block and a clamping block, so that the handle can be turned out when the corrugated cardboard box body is transported, which not only facilitates the transportation of the corrugated cardboard box body, but also prevents dust and moisture from entering the corrugated cardboard box body.

[0004] Based on the above search and combined with the prior art, it is found that the above patent has certain defects. The handle is a whole. When multiple corrugated cardboard boxes are transported and moved, it is not convenient to place the sling or hanger inside the handle for pulling. The hidden handle is not limited and is easily moved out due to vibration during transportation. It increases the occupied space and is also easily damaged, reducing the efficiency of the use of the corrugated cardboard boxes. Utility Model Content

[0022] The utility model is described in detail below, and the technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] The utility model provides a corrugated paper box with hidden handles through improvement. The technical solution of the utility model is:

[0024] like Figure 1-Figure 4 As shown, a corrugated paper box with a hidden handle comprises a box body 1, mounting holes 2 are provided on both side outer walls of the box body 1, mounting brackets 3 are provided on the inner walls of the mounting holes 2, a mounting groove is provided on one side outer wall of the mounting bracket 3, a support rod 6 is fixedly connected to the top inner wall of the mounting groove, a damping shaft 1 is provided on one side outer wall of the support rod 6, a handle 1 4 is movably connected to the outer wall of the damping shaft 1, a damping shaft 2 is provided on the other side outer wall of the support rod 6, a handle 2 5 is movably connected to the outer wall of the damping shaft 2, the handle 1 4 and the handle 2 5 are both L-shaped, a rectangular groove 13 is provided on the bottom outer wall of the handle 1 4, a rectangular protrusion 11 is provided on the bottom outer wall of the handle 2 5, circular grooves are provided on both side outer walls of the bottom of the mounting groove, a spring 14 is fixedly connected to the inner wall of the circular groove, a limiting ball 9 is fixedly connected to the inner wall of one side of the spring 14, and a limiting groove 12 is provided on the outer walls of the handle 1 4 and the handle 2 5.

[0025] Furthermore, the limiting balls 9 are adapted to the size of the circular grooves, the rectangular protrusions 11 are adapted to the size of the rectangular grooves 13, the bottom outer walls of handle 1 4 and handle 2 5 are bonded with anti-skid pads 10, the limiting balls 9 are hemispherical, the limiting balls 9 are adapted to the size of the limiting grooves 12, and the anti-skid pads 10 arranged at the bottom of handle 1 4 and handle 2 5 increase friction.

[0026] Furthermore, the top and bottom outer walls of the mounting frame 3 are fixedly connected with a fixing plate 7, and the outer walls on both sides of one side of the fixing plate 7 are provided with fixing holes 8. The outer wall on the other side of the mounting frame 3 is bonded with a sealing gasket 15, and the sealing gasket 15 is adapted to the size of the mounting hole 2. The inner wall on the other side of the mounting frame 3 is fixedly connected with a water-absorbing plate 16, and the water-absorbing plate 16 is made of bamboo fiber and is more environmentally friendly. The sealing gasket 15 arranged on the mounting frame 3 increases the structural sealing effect, and the water-absorbing plate 16 increases the structural water absorption effect, thereby further preventing moisture from entering the interior of the box body 1 through the mounting hole 2.

[0027] Working principle: When the corrugated box is not in use, the handle structures on both sides of the box body 1 are stored and hidden, and the handle 1 4 and the handle 2 5 on the support rod 6 are rotated and stored inside the mounting frame 3 through the damping shaft 1 and the damping shaft 2. When the box body 1 needs to be transported and moved, the handle 1 4 and the handle 2 5 are pulled in turn to rotate them from the vertical state to the horizontal state in turn. The handle 1 4 and the handle 2 5 are limited by the top of the mounting groove on the mounting frame 3 and cannot rotate anymore. The handle 1 4 and the handle 2 5 are spliced ​​into a complete handle through the rectangular protrusion 11 and the rectangular groove 13, and then pulled and transported by workers. The hanger or sling can be directly placed in the gap between the handle 1 4 and the handle 2 5. When the box 1 is inserted, the hanger or sling directly applies force to the handle 2 5, and the handle 2 5 supports the handle 1 4. The handle 1 4 and the handle 2 5 are stably U-shaped to carry the box 1. The handle 1 4 and the handle 2 5 press the limiting ball 9 when they are stored. After they are completely stored into the mounting frame 3, the limiting ball 9 enters the limiting groove 12 under the action of the spring 14, and limits the handle 1 4 and the handle 2 5 to prevent shaking. The anti-slip pad 10 arranged at the bottom of the handle 1 4 and the handle 2 5 increases the friction force, the sealing pad 15 arranged on the mounting frame 3 increases the structural sealing effect, and the water absorption plate 16 increases the structural water absorption effect, so as to further prevent moisture from entering the box 1 through the mounting hole 2.

[0028] The technical means disclosed in the utility model are not limited to the technical means disclosed in the above technical means, but also include technical solutions composed of equivalent replacement of the above technical features. Matters not covered in the utility model belong to the common knowledge of those skilled in the art.
