Description

Technical Field

[0001] The utility model relates to the technical field of logistics distribution, and more specifically, to a logistics box and a logistics transport component. Background Art

[0002] With the development of the times, people are paying more and more attention to health, and the number of chain drugstores is also increasing. Compared with traditional pharmacies, chain drugstores are limited by area, cost and market, and the drugs in them are of many types and small quantities. Single drugstores cannot purchase large quantities from pharmaceutical factories. Therefore, today's pharmacy distribution model often also has a drug storage and distribution center, which is used for large-scale purchase and storage, and sorts small quantities of drugs from large quantities of drugs according to the needs of each store, and then packs them separately and delivers them to the corresponding stores. In this process, a large number of logistics boxes are required, and improving the structure of logistics boxes is very helpful to improve the drug distribution efficiency of drug storage and distribution centers.

[0003] Chinese patent CN109867012A discloses a movable logistics box. By opening mounting holes at the four corners of the bottom end of the box body, and then setting fixing bolts in all the mounting holes, the wheels can be fixed to the bottom end of the box body by connecting the connecting pipes at the top ends of the wheels with the fixing bolts. When it is necessary to transport heavy goods, the box body can be pulled to move, reducing manpower consumption; positioning holes are set at the four corners of the box cover. When it is necessary to stack boxes, the wheels of the bottom box body are removed, and then the remaining boxes are fixed on top of the box body, and the wheels at the bottom end of the upper box body are fixed in the positioning holes, which not only does not take up more space, but also does not affect stacking; a pull rod is set on one side of the box body. When it is necessary to pull the box body, the connecting bolt at the end of the pull rod is fixed in the hole at the top end of the connecting hole. When it is necessary to stack the boxes, the connecting bolt is fixed in the hole at the bottom end of the connection, which is more convenient to use. However, there is a problem with this type of logistics box. Its limiting method is to limit the position through vertical connecting bolts. When passing through uneven roads during transportation, vertical jumping occurs between the boxes, which can easily cause them to fall off and collapse. Therefore, a logistics box with a more stable connection when stacked is needed. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and provide a logistics box and a logistics transport component, which can ensure that the connections between the various logistics boxes are firm and not prone to collapse.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A logistics box is provided, comprising a main box body and a cover plate, wherein a plug-in portion extending in a vertical direction is provided at the bottom of the main box body, a movable pin extending and retracting in a horizontal direction is provided on the plug-in portion, the movable pin is slidably connected to the plug-in portion, the cover plate is movably connected to the top of the main box body, a first plug-in groove cooperating with the plug-in portion is provided on the top of the cover plate, a first plug-in hole cooperating with the movable pin is provided in the first plug-in groove, and a control component for controlling the extension and retraction of the movable pin is also provided on the main box body.

[0007] With this arrangement, when multiple logistics boxes need to be stacked, transported or stacked, the plug-in portion of the upper logistics box is inserted into the first plug-in slot of the lower logistics box along the vertical direction. Through the cooperation between the plug-in portion and the first plug-in slot, the horizontal displacement of the two logistics boxes relative to each other is limited. In addition, during the insertion process, the control component controls the movable pin to retract. After the insertion is completed, the control component controls the movable pin to extend horizontally and insert into the first plug-in hole, thereby limiting the vertical displacement of the two logistics boxes relative to each other. Under the joint action of the plug-in portion and the movable pin, the connection between the logistics boxes is ensured to be firm and will not separate or collapse during transportation.

[0008] Preferably, a holding boss for easy carrying is further provided on the top of the main box body, the holding boss is protruding in the horizontal direction, and the cover plate is rotatably connected to the top of the holding boss.

[0009] With this arrangement, the user can grasp the holding boss to carry the logistics box, making it easier for the user to move the logistics box or stack the logistics boxes.

[0010] Preferably, a handle is provided on the holding boss, and the handle is slidably connected to the holding boss. A cavity is also provided in the box wall of the main box body, and the cavity communicates with the holding boss and the plug-in part. The control component is arranged in the cavity, and the control component connects the handle and the movable pin. The handle controls the extension and retraction of the movable pin through the control component.

[0011] With this arrangement, when the user is carrying the logistics box, the user grasps the handle with his hand, the handle is subjected to force and the control component controls the movable pin to retract, thereby preventing the movable pin from affecting the connection between the plug-in part and the first plug-in slot during the stacking process. When the stacking is completed, the plug-in part is plugged into the first plug-in slot, the user releases the handle, and the movable pin extends into the first plug-in hole, thereby completing a stable connection between different logistics boxes.

[0012] Preferably, the control assembly includes a rotating rod, a transmission rod, a connecting piece and an elastic piece. The handle is slidingly connected to the bottom of the holding boss, the middle part of the rotating rod is rotationally connected to the main box body, and both ends of the rotating rod are rotationally connected to the top of the handle and the top of the transmission rod respectively. A sloped platform is provided at the bottom end of the transmission rod, and a sloped groove corresponding to the sloped platform is provided in the middle part of the connecting piece. One end of the connecting piece is fixedly connected to a movable pin, and the other end of the connecting piece is connected to the plug-in part through an elastic piece. The elastic piece is in a compressed state, and the inclined surface of the sloped platform is arranged toward the elastic piece.

[0013] With this arrangement, when the user lifts the box, the hand is located at the bottom of the gripping boss, and the handle is forced to move upward, driving the rotating rod to rotate, and the other end of the rotating rod moves downward, driving the transmission rod to be pressed down, and the inclined platform at the bottom end of the transmission rod is inserted into the inclined groove, causing the connecting piece to move in the direction of the elastic piece, and the elastic piece is further compressed, and the movable pin is retracted into the plug-in part. At this time, the connection between the plug-in part and the first plug-in slot is not affected; when the plug-in part of the logistics box is connected with the first plug-in slot of the other logistics box, the user releases the handle, and the transmission rod is not subjected to the downward force. Under the action of the elastic piece, the connecting piece moves in the direction of the movable pin, the transmission rod is lifted up, and the movable pin is extended and plugged into the first plug-in hole, thereby completing the limit fixation between the two logistics boxes.

[0014] Preferably, a centralizing groove with a chamfered pyramid structure is provided at the bottom of the inner side of the main box body, the centralizing groove is concave in the middle, and the side walls of the centralizing groove are inclined.

[0015] With this arrangement, when the main box is loaded with goods, the goods will be concentrated in the concave middle part of the central groove under the action of gravity due to the chamfered terrace structure of the central groove, preventing the goods from gathering to one side due to inertia during the distribution process. This is conducive to making the center of gravity of the logistics box located in the middle of the main box, thereby improving the stability of the logistics box during stacking and transportation.

[0016] Preferably, the plug-in portion is a boss with a "mouth"-shaped structure, and the movable pin is slidably arranged inside the plug-in portion.

[0017] Through this arrangement, the force between the plug-in part and the first plug-in groove is evenly distributed, avoiding stress concentration caused by unilateral force, which is beneficial to improving the life of the logistics box; and the plug-in part can also protect the movable pin to avoid failure of the movable pin due to external collision.

[0018] Furthermore, the bottom of the movable pin is a wedge structure, and the top of the movable pin is a flat plate structure.

[0019] Through this arrangement, when multiple logistics boxes are stacked, when the plug-in part of the upper logistics box is inserted into the first plug-in slot, the wedge surface of the movable pin abuts against the first plug-in slot. Because the pressure applied is perpendicular to the slope, the movable pin will automatically retract and will not affect the connection between the plug-in part and the first plug-in slot. After the movable pin is inserted into the first plug-in hole, the wedge surface loses the pressure brought by the abutment, and the movable pin automatically extends out. When a vertical movement trend occurs between the logistics boxes, the flat surface on the top of the movable pin can still ensure that the movable pin provides a stable limiting effect.

[0020] Preferably, the cover plate includes a first plate and a second plate, the first plate and the second plate are hinged to two opposite sides of the top of the main box body respectively, the first plug-in slot portion is arranged at the top of the first plate, and the remaining portion of the first plug-in slot is arranged at the top of the second plate.

[0021] Through this arrangement, the first plate and the second plate can be rotated and opened to both sides of the main box body respectively, which is convenient for taking and placing goods, and when the logistics boxes are stacked, the rotation direction of the first plate and the second plate can be limited by the upper logistics box, and the first plate and the second plate limit the horizontal and vertical movement of the upper logistics box. The first plate and the second plate of the upper logistics box and the lower logistics box restrict and restrain each other, which is conducive to improving the stability of the connection between the logistics boxes.

[0022] A logistics transport component comprises a plurality of logistics boxes as described in any one of the above items and a plurality of mobile bases, wherein a plurality of universal wheels are provided at the bottom of the mobile base, a second plug-in slot cooperating with a plug-in portion is provided at the top of the mobile base, a second plug-in hole cooperating with a movable pin is also provided in the second plug-in slot, and the plurality of logistics boxes are stacked in sequence along the vertical direction, the plug-in portion of the bottom logistics box is plugged into the second plug-in slot of the mobile base, and the movable pin is plugged into the second plug-in hole.

[0023] Through this arrangement, a mobile base can be installed at the bottom of the logistics box to facilitate the movement of the logistics box. The plug-in part is connected to the second plug-in slot of the mobile base, and the movable pin is connected to the second plug-in hole. This can also ensure that the logistics box and the mobile base are firmly connected, avoiding the logistics box and the mobile base from being separated due to inertia or bumps when the logistics transport component is moved.

[0024] Preferably, a first connecting platform is provided on the side of the mobile base, a second connecting platform is provided on the opposite side of the first connecting platform, the first connecting platform and the second connecting platform are detachably connected, and a plurality of mobile bases are connected through the cooperation between the first connecting platform and the second connecting platform.

[0025] Through this arrangement, multiple mobile bases can be connected to each other in the horizontal direction through the cooperation between the first connecting platform and the second connecting platform, so that the user can move multiple groups of logistics boxes at one time.

[0026] Preferably, the first connecting platform and the second connecting platform are both L-shaped structures, the first connecting platform is fixedly installed above the side of the mobile base, and the second connecting platform is fixedly installed below the side of the mobile base, the first connecting platform is provided with a plurality of connecting blocks, and the second connecting platform is provided with a plurality of connecting grooves, and the plurality of connecting blocks correspond to and are plugged into the plurality of connecting grooves one by one.

[0028] Compared with the prior art, the beneficial effects of the utility model are:

[0029] (1) Through the cooperation between the plug-in part, the movable pin and the first plug-in part and the first plug-in hole, the limiting in multiple directions is achieved, so that the stacked connection between each logistics box is stable, and the separation of the logistics boxes during transportation is avoided.

[0030] (2) By setting the handle and the control component, the movable pin will automatically retract during transportation, which will not affect the coordination between the logistics boxes and improve work efficiency.

[0055] With this arrangement, when the main box body 1 is loaded with goods, due to the chamfered terrace structure of the central groove 16, the goods will be concentrated in the concave middle part of the central groove 16 under the action of gravity, preventing the goods from gathering to one side due to inertia during the distribution process. This is beneficial for making the center of gravity of the logistics box in the middle of the main box body 1, thereby improving the stability of the logistics box during stacking and transportation.

Because the pressure applied is perpendicular to the slope, the movable pin 12 will automatically retract and will not affect the connection between the plug-in portion 11 and the first plug-in slot 21. After the movable pin 12 is inserted into the first plug-in hole 22, the wedge surface loses the pressure brought by the abutment, and the movable pin 12 automatically extends out.
