Description

Technical Field

[0001] This utility model relates to the field of cardboard box technology, and in particular to a pressure-resistant cardboard box. Background Technology

[0002] Cardboard boxes are commonly used as wrapping materials for goods or as protective outer layers for items. The size of a cardboard box varies depending on the size of the goods. Cardboard boxes usually have various graphic or textual warnings such as "Handle with care," "Keep dry," "Head up," "Stacking limit," "Keep away from sunlight," "Moisture-proof," "Quality and safety," "Do not roll," "Do not trample," "Fire prevention," "Fragile," "Environmentally friendly," "Keep away from heat," "Food," and "Odor prevention" to remind users to pay attention and protect the contents from damage.

[0003] However, existing cardboard boxes generally do not have anti-compression devices installed inside, causing the cardboard box to deform under the pressure of heavy objects, thereby reducing the service life of the cardboard box. Furthermore, some devices that support the cardboard box cannot be removed according to the actual situation, reducing the adaptability of the device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies. By utilizing the cooperation of a worm gear and a worm wheel, two rotating rods are made to rotate, thus causing the two rotating rods to move at opposite speeds. This causes the two rotating rods to drive multiple connecting seats to rotate, making the support rods gradually move from the horizontal direction to the vertical direction. The multiple support rods support the box body, thereby improving the box body's pressure resistance. This invention provides a pressure-resistant cardboard box.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pressure-resistant cardboard box includes a box body, a fixing plate inside the box body, through slots at the four corners of the fixing plate, connecting seats in multiple through slots, support rods on opposite sides of multiple connecting seats, grooves on both sides of the fixing plate, a rotating mechanism for rotating the connecting seats between the groove and two through slots on the same side, and limiting mechanisms for limiting the support rods on both inner walls of the box body.

[0007] Preferably, the rotating mechanism is rotatably connected to a rotating rod between a groove on the same side and two through slots. The rotating rod passes through two connecting seats and is fixedly connected to them. A worm gear is provided on the outer wall of the rotating rod within the groove.

[0008] Preferably, the limiting mechanism includes a locking block disposed on the inner wall of the box, the locking block and the through groove being on the same horizontal plane, the locking block having a locking groove, and limiting blocks being elastically connected through both sides of the locking groove, the side wall of the limiting block having an inclined surface, and the inclined surface being slidably connected to the outer wall of the support rod.

[0009] Preferably, the lower end of the fixing plate is provided with a bottom groove, and a transmission rod is rotatably connected between the two grooves and the bottom groove. Both ends of the transmission rod are provided with worm gears, and the worm gears on the same side cooperate with worm wheels. The two pairs of worm gears and worm wheels have opposite helical directions.

[0010] Preferably, the upper end of the fixing plate is provided with a placement groove, and an operating rod is rotatably connected between the placement groove and the bottom groove.

[0011] Preferably, both the lower end of the operating lever and the outer wall of the transmission rod are provided with bevel gears, and the two bevel gears mesh with each other.

[0012] The beneficial effects of this utility model are:

[0013] 1. By utilizing the cooperation of the worm and worm wheel, the two rotating rods rotate, thus causing them to move at opposite speeds. This drives multiple connecting seats to rotate, making the support rods gradually move from the horizontal direction to the vertical direction. The multiple support rods support the box body, thereby improving the box body's compressive strength.

[0014] 2. By moving the support rods out of the slots, the multiple support rods return to their initial positions due to the tilt of the support rods and the action of gravity, thereby contacting the support rods to support the box and improving the adaptability of the device.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] Reference Figure 1-4 A pressure-resistant cardboard box includes a box body 1. A fixing plate 2 is provided inside the box body 1. Each of the four corners of the fixing plate 2 has a through groove 3. Each through groove 3 has a connecting seat 6. Each connecting seat 6 has a support rod 7 on its opposite side. Each side of the fixing plate 2 has a groove 4. A rotating mechanism for rotating the connecting seat 6 is provided between the groove 4 on the same side and the two through grooves 3. The rotating mechanism passes through and is rotatably connected to a rotating rod 5 between the groove 4 on the same side and the two through grooves 3. The rotating rod 5 passes through the two connecting seats 6 and is fixedly connected to them. A worm gear 11 is provided on the outer wall of the rotating rod 5 inside the groove 4.

[0023] Both sides of the inner wall of the housing 1 are provided with limiting mechanisms for limiting the support rods 7. The limiting mechanisms include a locking block 12 set on the inner wall of the housing 1. The locking block 12 is on the same horizontal plane as the through groove 3. A locking groove 13 is opened on the locking block 12. Limiting blocks 14 are elastically connected through both sides of the locking groove 13. An inclined surface 15 is opened on the side wall of the limiting block 14. The inclined surface 15 is slidably connected to the outer wall of the support rod 7. By moving the support rod 7 out of the locking groove 13, due to the inclination of the support rod 7 and the action of gravity, multiple support rods 7 return to the starting position, thereby contacting the support rod 7 to support the housing 1, thereby improving the adaptability of the device.

[0024] The lower end of the fixed plate 2 has a bottom groove 8. A transmission rod 9 is rotatably connected between the two grooves 4 and the bottom groove 8. Both ends of the transmission rod 9 are provided with worm gears 10. The worm gears 10 on the same side cooperate with the worm wheel 11. The two pairs of worm gears 10 and worm wheel 11 have opposite spiral directions. By utilizing the cooperation of the worm gears 10 and worm wheel 11, the two rotating rods 5 are rotated, thus causing the two rotating rods 5 to move at opposite speeds. Therefore, the two rotating rods 5 drive multiple connecting seats 6 to rotate, so that the support rods 7 gradually tend to be vertical from the horizontal direction, and the multiple support rods 7 support the box 1, thereby improving the pressure resistance of the box 1.

[0025] The upper end of the fixed plate 2 is provided with a placement groove, and an operating rod 16 is rotatably connected between the placement groove and the bottom groove 8.

[0026] Both the lower end of the operating lever 16 and the outer wall of the transmission rod 9 are provided with bevel gears 17, and the two bevel gears 17 mesh with each other.

[0027] In use, when supporting the housing 1, rotating the operating lever 16 causes the transmission rod 9 to rotate due to the meshing of the two bevel gears 17 between the operating lever 16 and the transmission rod 9. This, in turn, causes the two worm gears 10 on the outer wall of the transmission rod 9 to rotate. The worm gears 10, in conjunction with the worm wheel 11, cause the two rotating rods 5 to rotate (the two pairs of worm gears 10 and worm wheel 11 rotate in opposite directions). This results in the two rotating rods 5 moving at opposite speeds, thus causing the two rotating rods 5 to drive the multiple connecting seats 6 to rotate, causing the support rod 7 to gradually move from the horizontal direction towards the vertical. When the support rod 7 contacts the two inclined planes 15, the operating rod 16 is rotated continuously. The through elastic connection between the limiting block 14 and the side wall of the slot 13 causes the support rod 7 to press the limiting block 14 to move, thereby increasing the distance between the two limiting blocks 14. As a result, the support rod 7 enters the slot 13 and returns to the starting position under the elastic action of the limiting block 14 (this part is prior art, so its related structure is not described in detail in this figure). This achieves the restriction of the position of the support rod 7, so that multiple support rods 7 support the box 1 and improve the compressive strength of the box 1.

[0028] When it is necessary to release multiple support rods 7, push the two limiting blocks 14 to release the limitation blocks 14 from the support rods 7, and move the support rods 7 out of the slot 13. Due to the tilt of the support rods 7 and the action of gravity, the multiple support rods 7 return to the starting position, thereby contacting the support rods 7 to support the box 1, thereby improving the adaptability of the device.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
