Description

Technical Field

[0001] The utility model relates to the field of cartons, in particular to a compression-resistant and shock-absorbing carton. Background Art

[0002] Cartons are the most widely used packaging products, usually used as wrapping for goods or as outer protective layers for items. The volume of a carton changes with the size of the goods. As an indispensable part of modern logistics, packaging cartons bear the important responsibilities of containing, protecting products, and being beautiful. There are also compression-resistant and shock-absorbing cartons that provide better bearing capacity. Its specific structure is like the compression-resistant carton proposed by CN220164426U. By inserting the bearing plate into the through groove, the bearing plate supports the heavy objects, and the support plate at the bottom of the bearing plate supports the bearing plate. The corrugated paper at the bottom of the bearing plate is light in weight and strong in strength, which further supports the heavy objects. A protective cover is attached at the connection of the side panels through the first adhesive. The protective sleeve enhances the pressure resistance of the connection to prevent the side panels from being damaged when subjected to force. The pressure-resistant component solves the problem that the carton is damaged because its own material cannot provide good bearing capacity when carrying heavy objects. When transporting heavy objects, the first shock-absorbing pad and the second shock-absorbing pad bonded to the inside of the carton body can perform shock-absorbing treatment. When liquid leaks, the waterproof membrane arranged between the first shock-absorbing pad and the second shock-absorbing pad blocks the liquid to prevent the carton from becoming soft after contacting water and being unable to carry heavy objects. The auxiliary components enhance the waterproof and shock-absorbing function of the carton and enhance the practicality of the carton.

[0003] The existing technology has solved the problem that the carton is not able to provide a good bearing capacity when carrying heavy objects due to its own material, which leads to damage to the carton by setting a bearing plate and a pressure-resistant component. However, the existing technology solution has the following defects in operation:

[0004] When the carton is being transported, the weight of the heavy objects in the carton acts on the lower side wall of the carton through the load-bearing plate, which may cause damage or even rupture of the lower side wall of the carton, causing the heavy objects in the carton to fall. Utility Model Content

[0005] The utility model aims to provide a pressure-resistant and shock-absorbing carton, which solves the technical problem that when the carton is being transported, the lower side wall of the carton may be damaged or even broken, causing heavy objects in the carton to fall.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] A pressure-resistant and shock-absorbing cardboard box includes a box body, and a reinforcing plate is installed on the lower side wall inside the box body. The characterised in that rope holes are symmetrically opened on the left and right sides of the box body, a pulling rope is passed through the rope holes, a conical cavity is symmetrically opened on the upper end surface of the reinforcing plate, a fixing component for fixing the pulling rope is inside the conical cavity and is slidably connected to the conical cavity, and one end of the pulling rope passes through the inner hole of the fixing component disc and is fixed with a fixing buckle.

[0008] The working principle and beneficial effects of this utility model:

[0009] 1. Working principle: When the box needs to be moved, the gravity of the heavy object in the box acts on the reinforcing plate, and the pulling rope that is slidably connected to the rope hole is pulled up. After the pulling rope is pulled, the box is moved up. Since the heavy object is placed on the reinforcing plate, and the stretched end is connected to the reinforcing plate through a fixed component, when the tension of the pulling rope pulls the reinforcing plate, the weight of the heavy object acts on the reinforcing plate and the pulling rope, thereby completing the transportation of the box.

[0010] 2.Beneficial effects:

[0011] The existing technology has solved the problem that the carton is damaged because its own material cannot provide good bearing capacity when carrying heavy objects by setting load-bearing plates and pressure-resistant components. However, when the box is being transported, the gravity of the heavy objects in the carton acts on the lower side wall of the carton through the load-bearing plate, which will further cause the lower side wall of the carton to be damaged or even ruptured, causing the heavy objects in the carton to fall. This solution provides a lifting rope and a fixing component. When the box is transported, the gravity of the heavy objects in the box acts on the reinforcing plate. Through the conical cavity opened on the reinforcing plate and the fixing component for fixing the lifting rope, the gravity of the heavy objects acting on the reinforcing plate is transmitted to the lifting rope, thereby avoiding the gravity of the heavy objects squeezing the lower side wall of the box, reducing the damage or even rupture of the lower side wall of the carton, and ensuring that the heavy objects in the box will not fall.

[0012] Preferably, the fixing assembly includes a disc slidably connected in the conical cavity, the top of the disc is fixedly connected to a buckle strip, the inner side of the lower end of the conical cavity is fixedly connected to a rubber ring, the rubber ring is located below the disc, the upper end surface of the disc is penetrated by a disc inner hole, one end of the pulling rope passes through the disc inner hole and is slidably connected to the disc inner hole; when the pulling rope is lifted, the fixing buckle fixedly connected to the end of the pulling rope passing through the disc inner hole moves upward along the axis direction of the conical cavity through the inner ring of the rubber ring until it contacts the bottom end of the disc, transmitting the pulling force to the disc. The tension drives the disc and the buckle strip fixedly connected to the top of the disc to move upward along the axial direction of the conical cavity until the buckle strip is against the upper inner wall of the conical cavity. At this time, the buckle strip is deformed and bent toward the outer wall of the pulling rope under the combined action of the tension and the extrusion of the upper inner wall of the conical cavity. The claw at the top of the buckle strip is stuck in the pulling rope to fix the pulling rope, reducing the tension borne by the fixing buckle and ensuring the stability of the pulling rope. At the same time, when the fixing buckle is subjected to excessive force and the pulling rope is detached, the buckle strip can also fix the pulling rope to prevent the pulling rope from falling off the box.

[0013] Preferably, there are multiple snap strips, which are evenly distributed in a circular array on the top of the disc. By setting up multiple snap strips, the total tension borne by the snap strips can be increased, and the tension borne by the fixing buckle can be reduced. When the fixing buckle is separated from the pulling rope due to excessive force, the pulling rope can be fixed by the snap strip to prevent the box from falling off.

[0014] Preferably, a claw is fixedly connected to one side of the upper end surface of the buckle strip; the claw can be tightly clamped into the rope to increase the fixation of the rope.

[0015] Preferably, the inner diameter of the rubber ring is not larger than the diameter of the disc; when the pulling rope is not in use, the disc and the buckle strip move downward along the axis of the conical cavity, and the rubber ring can prevent the disc and the buckle strip from moving down and out of the conical cavity. When used again, the disc and the buckle strip will not be unable to move upward along the axis of the cavity due to the disc and the buckle strip being no longer in the conical cavity.

[0016] Preferably, the interior of the box is slidably connected with a paper baffle, a slide groove is provided at the bottom end of the paper baffle, and a slide rail compatible with the slide groove is fixedly installed on the upper end surface of the reinforcement plate; multiple paper baffles can move along the slide rail in the box through the slide groove provided at the bottom, thereby changing the size of the storage space of the box, so that the box can load goods of different sizes, increasing the practicality of the box; when the box only needs to load one item, the paper baffle is moved through the slide groove and the slide rail to fit the internal side panel of the carton, thereby increasing the pressure resistance and shock absorption capacity of the side panel of the carton.

[0017] Preferably, jacks are symmetrically provided on both sides of the top cover of the box body, and sealing strips are inserted into the jacks. The top plate of the box body can be fixed by the sealing strips and the jacks, making it convenient for staff to seal the top plate of the box body with tape. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figure 1-Figure 5As shown, a reinforcing plate 12 is installed on the lower side wall inside the box body 1, which is characterized in that rope holes are symmetrically opened on the left and right sides of the box body 1, and a pulling rope 2 is passed through the rope holes. A conical cavity 8 is symmetrically opened on the upper end surface of the reinforcing plate 12, and a fixing component for fixing the pulling rope 2 is provided inside the conical cavity 8 and in sliding connection with the conical cavity 8. The fixing component includes a disc 6 that is slidably connected in the conical cavity 8, and a buckle strip 7 is fixedly connected to the top of the disc 6. There are multiple buckle strips 7, which are evenly distributed in a circular array at the top of the disc 6. A claw 15 is fixed to one side of the upper end surface of the buckle strip 7. A rubber ring 13 is fixed to the inner side of the lower end of the conical cavity 8. The rubber ring 13 is located below the disc 6. The inner diameter of the rubber ring 13 is not greater than the diameter of the disc 6. A disc inner hole 14 is opened on the upper end surface of the disc 6. One end of the pulling rope 2 passes through the disc inner hole 14 and is slidably connected to the disc inner hole 14. One end of the pulling rope 2 passes through the disc inner hole 14. The inner hole 14 of the fixed component disc is fixed with a fixing buckle 9. When the pulling rope 2 is lifted, the fixing buckle 9 fixedly connected to one end of the pulling rope 2 passing through the inner hole 14 of the disc moves upward along the axis direction of the conical cavity 8 through the inner ring of the rubber ring 13 until it contacts the bottom end of the disc 6, transmitting the pulling force to the disc 6. The pulling force drives the disc 6 and the buckle strip 7 fixedly connected to the top of the disc 6 to move upward along the axis direction of the conical cavity until the buckle strip 7 contacts the conical cavity 8. The upper inner walls are against each other. At this time, the buckle strip 7 is deformed and bent toward the outer wall of the pulling rope 2 under the combined action of tension and the extrusion of the upper inner wall of the conical cavity 8. The claw 15 at the top of the buckle strip 7 is clamped into the pulling rope 2 to fix the pulling rope 2, reducing the tension on the fixing buckle 9 and ensuring the stability of the pulling rope 2. At the same time, when the fixing buckle 9 is subjected to excessive force and the pulling rope 2 is detached, the buckle strip 7 can also fix the pulling rope 2 to prevent the pulling rope 2 from falling off the box body 1.

[0027] like Figure 2-Figure 3 As shown, the interior of the box body 1 is slidably connected with a paper baffle 4, and a slide groove 11 is provided at the bottom end of the paper baffle 4. A slide rail 5 adapted to the slide groove 11 is fixedly installed on the upper end surface of the reinforcing plate 12. Multiple paper baffles 4 can move along the slide rail 5 in the box body 1 through the slide groove 11 provided at the bottom, thereby changing the size of the storage space of the box body 1, so that the box body 1 can be loaded with goods of different sizes, thereby increasing the practicality of the box body 1. When the box body 1 only needs to be loaded with one item, the paper baffle 4 is moved through the slide groove 11 and the slide rail 5 to fit the inner side panel of the carton 1, thereby increasing the pressure resistance and shock absorption capacity of the side panel of the carton 1.

[0028] like Figure 6 As shown, jacks 10 are symmetrically provided on both sides of the top cover of the box body 1, and sealing strips 3 are inserted into the jacks 10. The top plate of the box body 1 can be fixed by the sealing strips 3 and the jacks 10, making it convenient for the staff to seal the top plate of the box body 1 with tape.

[0029] From the above, it can be seen that the specific implementation of the present utility model is as follows:

[0030] When the box needs to be moved, the gravity of the heavy object in the box 1 acts on the reinforcing plate 12, and the pulling rope 2 connected to the rope hole is pulled up. After the pulling rope 2 is pulled, the box 1 moves up. Since the heavy object is prevented from being on the reinforcing plate 12, the pulling rope 2 passes through the fixing buckle 9 fixedly connected at one end of the inner hole of the disc 6 and moves upward along the axis direction of the conical cavity 8 through the inner ring of the rubber ring 13 until it contacts the bottom end of the disc 6, transmitting the pulling force to the disc 6, and the pulling force drives the disc 6 to be fixedly connected to the top of the disc The buckle strip 7 moves upward along the axial direction of the conical cavity 8 until the buckle strip 7 is against the upper inner wall of the conical cavity 8. At this time, the buckle strip 7 is deformed and bent toward the outer wall of the lifting rope 2 under the combined action of tension and the extrusion of the upper inner wall of the conical cavity 8. The buckle at the top of the buckle strip 7 is inserted into the lifting rope 2 to fix the lifting rope 2. Therefore, when the tension on the lifting rope 2 pulls the reinforcing plate 12, the weight of the heavy object acts on the reinforcing plate 12 and the lifting rope 2, thereby completing the transportation of the box 1.

[0031] When heavy objects are placed in the carton, the multiple paper baffles 4 can move along the slide rails 5 in the box body 1 through the slide grooves 11 provided at the bottom to protect the outer wall of the heavy objects.

[0032] When the box body 1 needs to be sealed, the sealing strip 3 is inserted into the insertion hole 10 to fix the top plate of the box body 1, and then the staff seals the box body 1 with tape.

[0033] The above is only an embodiment of the present invention, and the commonly known specific structures and characteristics of the scheme are not described in detail here. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, and these should also be regarded as the scope of protection of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection claimed by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
