Technical Field

[0001] The invention relates to the technical field of packaging limiting structures, and in particular to a rotation limiting mechanism. Background Art

[0002] When loading equipment into an equipment packaging box, the gap between the equipment and the packaging box is small due to the small space of the packaging box. If a general wrap-around clamp is used for limiting, the gap between the equipment and the packaging box will be further reduced. In order to prevent the packaging box wall from colliding with the equipment, the installation will rely entirely on manpower. For equipment with irregular shapes, it is not convenient to limit the equipment after it is placed in the box. Summary of the invention

DETAILED DESCRIPTION

[0012] To facilitate those skilled in the art to understand the present invention, specific implementations of the present invention are described below with reference to the accompanying drawings.

[0013] like Figures 1 to 5 As shown, the present invention provides a rotation limiting mechanism, including a box body 1, a plurality of grooves 2 are provided on the inner wall of the box body 1, a rotation limiting assembly is arranged in the groove 2, the rotation limiting assembly includes two rod bodies 3, the adjacent ends of the two rod bodies 3 are fixedly installed with shafts 4, the ends of the shafts 4 are rotatably connected with the inner wall of the groove 2, first gears 5 are installed on the two shafts, the two first gears are meshed with each other, one of the shafts is connected to a power assembly, and the shaft can be driven to rotate through the power assembly, the power assembly is embedded in the inner wall of the box body, the power assembly is connected to the corresponding shaft through a sprocket assembly, an extrusion part is arranged on the other end of the rod body, the shaft is driven to rotate a certain angle through the power assembly, the rod body rotates toward the inside of the box body, and the goods 15 in the box body are limited by the extrusion part.

[0014] The extrusion part comprises an extrusion block 6, and an elastic buffer block 7 is arranged on the side of the extrusion block. When the extrusion block limits the goods, the contact surface with the goods is soft and elastic through the design of the elastic buffer block, which can protect the goods.

[0015] The extrusion block is hingedly connected to the corresponding rod body, and a through hole 8 is provided in the extrusion block. The same elastic hose 9 passes through the through hole of the two extrusion blocks of the same limiting assembly. Both ends of the elastic hose are sealed and fixedly connected to the inner wall of the box. Through this design, when limiting the position of the goods, the rotation of the rod body toward the inside of the box can drive the corresponding elastic hose to move at the same time. The elastic hose can fit the irregular surface of the goods, thereby improving the limiting effect of the goods.

[0016] A plug 10 is arranged inside the elastic hose at a position corresponding to the through hole, a plurality of strong magnetic rings 11 are embedded in the outer ring of the plug, and an attraction ring 12 which can be attracted by the strong magnetic ring is embedded in the inner wall of the through hole at the position corresponding to the strong magnetic ring. The cooperation between the strong magnetic ring and the attraction ring can realize that the plug is maintained in the position inside the through hole. When the rod body rotates toward the inside of the box body, the two extrusion blocks in the same group approach each other. Under the magnetic attraction, the plug will slide in the elastic hose. The two plugs approach each other, and the air pressure in the space between the two plugs inside the hose will increase, resulting in a certain degree of expansion. The expanded elastic hose can better fit the surface of the goods and better limit the position of the goods.

[0017] An annular airbag 13 is embedded in the through hole, and the inner circle of the annular airbag fits with the outer side surface of the elastic hose. An annular groove 14 is provided at the position of the plug corresponding to the annular airbag. The annular airbag is connected to an inflation structure, which is not shown here. When in use, the two extrusion blocks in the same group approach each other, and the plug will slide in the elastic hose under magnetic attraction. The two plugs approach each other, and the air pressure in the space between the two plugs inside the hose will increase and expand to a certain extent. Then, the annular airbag is quickly inflated through the inflation structure. The expansion of the annular airbag can press the outer wall of the elastic hose, and the elastic hose is deformed and fits with the annular groove 14. At this time, the annular airbag seals the position of the elastic hose, and the plug is also squeezed inside the through hole and cannot move, which can maintain the expansion between the two plugs inside the hose, further ensuring that the expanded elastic hose can better fit the surface of the cargo.

[0018] When in use, first place the goods inside the box, drive the shaft to rotate a certain angle through the power component, and the rod body rotates toward the inside of the box, and the goods in the box are limited by the extrusion part. The elastic hose between the two plugs can be expanded to a certain extent through the cooperation of the extrusion block, the plug, the strong magnetic ring and the attraction ring. The expanded elastic hose can fit the irregular surface of the goods to improve the limiting effect of the goods, and can hold goods of different shapes to achieve the limiting of the goods. The limiting component and the box can be integrated, and when the rod body is retracted into the groove, the inner wall of the box can still remain flat. At this time, there is a certain gap between the inner wall of the box and the goods, which is convenient for taking and putting goods. The staff can quickly and conveniently place the goods in the box and limit them through the present invention, and the goods are not easily damaged during transportation.

[0019] The above-described embodiments of the present invention do not constitute a limitation on the protection scope of the present invention. Any modification, equivalent substitution and improvement made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
