Abstract
Description
Technical Field
[0001] This application relates to the field of logistics box technology, specifically a shockproof logistics box for logistics transportation. Background Technology
[0002] In the field of logistics and transportation, logistics boxes are an important tool for packaging and transporting goods, and their performance directly affects the safe transportation and integrity of goods upon arrival.
[0003] Chinese utility model patent CN220221529U discloses an anti-bump logistics box for transportation. It uses eight dampers, each with a spring on its outer surface. A storage box is placed between the eight dampers. When the box itself is subjected to vibration, the springs and dampers work together to cushion the impact, reducing the vibration experienced by the items inside. However, the cushioning force provided by the springs is fixed, which limits its use. If the cushioning force is too strong, lightweight goods may shake inside the box, increasing the risk of damage. If the cushioning force is too weak, heavier goods may not be effectively absorbed, also causing damage.
[0004] Therefore, this application provides a shockproof logistics box for logistics transportation to solve the above problems. Utility Model Content
[0005] This application provides a shockproof logistics box for logistics transportation, aiming to solve the problems mentioned in the background art, such as the fixed spring cushioning force of existing logistics boxes, which makes it difficult to adapt to the transportation needs of goods of different weights and poses a risk of goods damage.
[0006] To achieve the above objectives, this application provides the following technical solution: a shockproof logistics box for logistics transportation, comprising an outer box body, an inner box body slidably connected to the outer box body, damping rods respectively fixedly disposed on the outer sides of the inner box body, and buffer springs sleeved on the outer side of the damping rods and fixedly connected to the inner box body.
[0007] The logistics box also includes a sleeve rod sleeved on the outside of the damping rod and fixedly connected to the side of the buffer spring away from the inner box body, and a pressing member disposed in the outer box body for sliding with the inner box body and pressing the sleeve rod to change the preload of the buffer spring. Through the pressing member, when goods are placed into the inner box body, the sliding of the inner box body can synchronously drive the pressing member to press the sleeve rod, causing the buffer spring to be compressed on the outside of the damping rod, thereby changing the preload of the buffer spring. This allows the logistics box to automatically adjust the cushioning force around the inner box body according to the weight of the goods, providing appropriate elastic cushioning potential energy for goods of different weights, improving transportation flexibility and safety.
[0008] Preferably, to ensure the stability of the extrusion sleeve, a guide block is fixedly installed on the outer side of the damping rod, and a guide groove is opened on the sleeve corresponding to the position of the guide block. The guide block is slidably connected in the guide groove. By making the guide block slidably connected in the guide groove, the movement trajectory of the extrusion component when extruding the sleeve can be ensured to be stable and accurate. This design prevents the sleeve from deviating or twisting when it is extruded, thereby ensuring that the buffer spring can be compressed to achieve the change of preload.
[0009] Preferably, to facilitate the compression of the sleeve rod and change the preload of the buffer spring, the compression component includes a sloping groove formed in the outer casing at the position corresponding to the damping rod, and a sloping block slidably connected in the sloping groove and fixedly connected to the outer side of the sleeve rod away from the damping rod. The inclination angle of the sloping groove increases from top to bottom. With the combination design of the sloping groove and the sloping block, when the inner casing slides down, the sloping block slides along the sloping groove. As the angle of the sloping groove gradually increases, the heavier the goods, the farther the sloping block slides down, and the greater the compression effect on the sleeve rod, resulting in a greater preload of the buffer spring. This adaptive adjustment mechanism ensures that the logistics box can provide a suitable cushioning effect regardless of the weight of the goods.
[0010] Preferably, in order to ensure that the inclined block does not detach from the inclined groove, limit rods are fixedly installed on both sides of the inclined block, and limit grooves are opened on both sides of the inclined block corresponding to the inclined groove. The limit rods are slidably connected in the limit grooves. The combined design of the limit rods and limit grooves restricts the movement range of the inclined block, so that the inclined block will not detach from the inclined groove during the sliding process in the inclined groove, thereby ensuring the stability and reliability of the extruded part.
[0011] Preferably, in order to achieve cushioning at the bottom of the inner box and automatic reset of the inner box after the goods are removed, the logistics box further includes a spring-loaded component disposed in the outer box at a position corresponding to the bottom of the inner box for moving, resetting, and cushioning the inner box; the design of the spring-loaded component not only absorbs the impact force when the inner box slides down, providing bottom cushioning for the inner box, but also, due to its own elasticity, automatically resets the inner box, the squeezing component, and the cushioning spring to their initial positions after the goods inside the inner box are removed, ensuring the logistics box can be used again.
[0012] Preferably, to facilitate the movement, reset, and cushioning of the inner box, the rebound assembly includes a fixed rod fixedly installed inside the outer box at the corners corresponding to the bottom of the inner box; a telescopic rod slidably connected to the top of the fixed rod and fixedly connected to the bottom of the inner box; and a return spring sleeved on the telescopic rod, with both ends fixedly connected to the inside of the fixed rod and the bottom of the inner box, respectively. With this design, when the inner box slides down due to the weight of the goods, the return spring is compressed, absorbing the impact. When the goods are removed, the return spring, due to its own elasticity, pushes the telescopic rod upward along the fixed rod, causing the inner box to automatically reset to its initial position. Simultaneously, the inner box will drive the buffer spring connected to the damping rod and the compression component to return to their original position, improving ease of use and eliminating the need for manual reset.
[0013] Preferably, to further improve the cushioning effect, the cushioning spring consists of three compression springs of different thicknesses, with the thickest compression spring in the middle and the thinnest compression springs at both ends. With this design, when the logistics box is subjected to external force, the thinnest compression springs at both ends begin to compress first, providing an initial cushioning effect. As the external force increases, the thickest compression spring in the middle gradually participates in the compression, providing stronger support. This progressive cushioning force can adapt to external forces of different magnitudes, reduce the impact on the logistics box and goods, and further improve the cushioning effect.
[0014] This anti-bump logistics box for transportation uses a compression component and a sleeve rod. When goods are placed into the inner box, the inner box slides down, which simultaneously drives the compression component to squeeze the sleeve rod. This causes the buffer spring to be compressed on the outside of the damping rod, thereby changing the preload of the buffer spring. This allows the logistics box to automatically adjust the cushioning force around the inner box according to the weight of the goods, providing appropriate elastic cushioning potential energy for goods of different weights, and improving transportation flexibility and safety.
[0015] This anti-bump logistics box for transportation uses a buffer spring composed of three compression springs of different thicknesses. The thick compression spring is located in the middle, and the two ends are thin compression springs. It can provide a progressive buffer force, adapt to different external forces, reduce the impact on the logistics box and goods, and further improve the buffering effect. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0030] Example 1
[0031] This embodiment provides a shockproof logistics box for logistics transportation, such as... Figures 1-4 As shown, the logistics box includes an outer box body 1, an inner box body 2 slidably connected inside the outer box body 1, damping rods 3 fixedly installed on the outer sides of the inner box body 2, and a buffer spring 4 sleeved on the outer side of the damping rods 3 and fixedly connected to the inner box body 2; the logistics box also includes a sleeve rod 5 sleeved on the outer side of the damping rods 3 and fixedly connected to the side of the buffer spring 4 away from the inner box body 2, and a pressing member 6 installed inside the outer box body 1 for sliding with the inner box body 2 and pressing the sleeve rod 5 to change the preload of the buffer spring 4.
[0032] In use, when goods need to be placed inside, the inner box 2 slides down inside the outer box 1 under the action of the goods. As the inner box 2 slides down, the damping rod 3, the buffer spring 4, and the sleeve rod 5 move accordingly. At this time, the pressing component 6 will press the sleeve rod 5 to slide outside the damping rod 3, and the sleeve rod 5 will press the buffer spring 4. The buffer spring 4 will be compressed after being compressed. Its degree of compression is related to the weight of the goods and the pressing force of the pressing component 6 on the sleeve rod 5. The heavier the goods, the greater the pressing force of the pressing component 6 on the sleeve rod 5, and the greater the degree of compression of the buffer spring 4. The stronger the preload, the greater the stored elastic potential energy. Therefore, when the outer box 1 is impacted by an external force, this impact force will be transmitted to the inner box 2. Since the inner box 2 is fixedly connected to the buffer spring 4, the impact force will cause the inner box 2 to try to move in the direction of the impact of the outer box 1. At this time, the buffer spring 4 will be further compressed, converting its stored elastic potential energy into resistance to the inner box 2. The buffer spring 4 absorbs and disperses the energy of the impact force during the compression process, thereby reducing the direct impact of the impact force on the inner box 2 and the goods.
[0033] Specifically, a guide block 31 is fixedly installed on the outside of the damping rod 3, and a guide groove 51 is opened at the position of the sleeve rod 5 corresponding to the guide block 31, and the guide block 31 is slidably connected in the guide groove 51;
[0034] When goods need to be placed, the inner box 2 slides down inside the outer box 1 under the action of external force. As the inner box 2 slides down, the squeezing member 6 moves synchronously and squeezes the sleeve rod 5. Since the guide groove 51 on the sleeve rod 5 cooperates with the guide block 31 on the outside of the damping rod 3 and forms a sliding connection, when the squeezing member 6 squeezes the sleeve rod 5, the sleeve rod 5 can move stably along an accurate path on the outside of the damping rod 3 through the sliding cooperation of the guide block 31 and the guide groove 51. As the sleeve rod 5 moves, it will drive one end of the buffer spring 4 connected to it to move closer to the end of the buffer spring 4 connected to the inner box 2. This movement causes the buffer spring 4 to be compressed. The degree of compression is related to the distance the inner box 2 slides down and the squeezing force of the squeezing member 6. Therefore, the heavier the goods, the greater the distance the inner box 2 slides down, and the greater the squeezing force of the squeezing member 6 on the sleeve rod 5, which leads to a greater degree of compression of the buffer spring 4, a stronger preload, and thus a greater elastic buffer potential energy.
[0035] Furthermore, the extrusion part 6 includes a slanted groove 62 opened inside the outer casing 1 at the position corresponding to the damping rod 3, and a slanted block 61 slidably connected in the slanted groove 62 and fixedly connected to the outer side of the sleeve rod 5 away from the damping rod 3. The inclination angle of the slanted groove 62 increases from top to bottom.
[0036] When goods need to be placed, the inner box 2 slides down inside the outer box 1 under the action of external force. As the inner box 2 slides down, the sleeve rod 5 also slides down synchronously due to its connection with the inner box 2, the damping rod 3, and the buffer spring 4. When the sleeve rod 5 slides down, the inclined block 61 fixed on the outer side of its end away from the damping rod 3 will slide along the inclined groove 62. Since the inclination angle of the inclined groove 62 increases from top to bottom, the inclined block 61 will be subjected to a gradually increasing horizontal compressive force during the descent. Then, the horizontal compressive force on the inclined block 61 will be transmitted to the sleeve rod 5, causing the sleeve rod 5 to slide along the outer side of the damping rod 3, and driving one end of the buffer spring 4 connected to it to move towards the end of the buffer spring 4 connected to the inner box 2. As the inner box 2 moves closer, this movement compresses the buffer spring 4. The degree of compression is related to the distance the inner box 2 slides down and the inclination angle of the inclined groove 62. Since the inclination angle of the inclined groove 62 increases from top to bottom, as the inner box 2 slides down, the horizontal squeezing force on the inclined block 61 gradually increases, thereby gradually increasing the degree of compression of the buffer spring 4 and correspondingly strengthening the preload, that is, increasing the elastic buffering potential energy. Therefore, the logistics box can adapt to goods of different weights and provide a better buffering effect. Furthermore, when the outer box 1 is impacted by an external force, the buffer spring 4 will provide a certain buffering force due to its stored elastic buffering potential energy, reducing the impact of external impact on the inner box 2 and the goods.
[0037] To ensure that the inclined block 61 does not detach from the inclined groove 62, limit rods 63 are fixedly installed on both sides of the inclined block 61. Limit grooves 64 are opened on both sides of the inclined groove 62 corresponding to the inclined block 61, and the limit rods 63 are slidably connected in the limit grooves 64. The combination design of the limit rods 63 and the limit grooves 64 means that when the inclined block 61 slides in the inclined groove 62, the limit rods 63 will also slide synchronously in the limit grooves 64. Due to the sliding cooperation of the limit rods 63 and the limit grooves 64, the movement range of the inclined block 61 in the inclined groove 62 is restricted. Therefore, the inclined block 61 will not detach from the inclined groove 62 during the movement, thereby ensuring the stability and reliability of the extruded part 6.
[0038] Furthermore, the logistics box also includes a spring-loaded assembly 7 located inside the outer box 1 at the bottom position corresponding to the inner box 2 for moving, resetting and buffering the inner box 2. The spring-loaded assembly 7 includes a fixed rod 71 fixedly installed inside the outer box 1 at the four corner positions corresponding to the bottom of the inner box 2, a telescopic rod 72 slidably connected to the top of the fixed rod 71 and fixedly connected to the bottom of the inner box 2, and a reset spring 73 sleeved on the telescopic rod 72 and fixedly connected at both ends to the inside of the fixed rod 71 and the bottom of the inner box 2, respectively.
[0039] When goods need to be placed inside, the inner box 2 slides down inside the outer box 1 under the action of external force. During the sliding process, the telescopic rod 72 shortens accordingly, and the return spring 73 is compressed. Due to the elastic potential energy of the return spring 73, it generates an upward elastic force on the inner box 2, thereby slowing down the sliding speed of the inner box 2 and achieving a buffering effect. When goods need to be removed, the telescopic rod 72 extends accordingly due to the elastic force of the return spring 73, and the return spring 73 gradually returns to its original length, thereby synchronously pushing the inner box 2 upward within the outer box 1 to return to its initial position. The damping rod 3, buffer spring 4, and sleeve rod 5 are connected so that when the inner box 2 moves upward and resets, the damping rod 3, buffer spring 4, and sleeve rod 5 also move upward synchronously. At the same time, the inclined block 61 also moves upward in the inclined groove 62 along with the guide groove 51. At this time, the horizontal squeezing force on the inclined block 61 gradually decreases, and the inclined block 61 will drive the sleeve rod 5 and buffer spring 4 to move away from the inner box 2 and reset to the initial position, so that the buffer spring 4 is stretched. This allows the compression degree of the buffer spring 4 to be adjusted according to the weight of the goods put into the inner box 2 next time, thus changing its preload.
[0040] Example 2
[0041] Unlike Example 1, as Figure 5 As shown, to further improve the cushioning effect, the cushioning spring 4 consists of three compression springs of different thicknesses, with the thickest compression spring in the middle and the thinnest compression springs at both ends. With this design, when the logistics box is subjected to external force, the thinnest compression springs at both ends begin to compress first, providing an initial cushioning effect. As the external force increases, the thickest compression spring in the middle gradually participates in the compression, providing stronger support. This progressive cushioning force can adapt to external forces of different magnitudes, reduce the impact on the logistics box and goods, and further improve the cushioning effect.
