Description

Technical Field

[0001] This utility model relates to the field of logistics box technology, and in particular to a logistics box for logistics freight. Background Technology

[0002] A logistics box is a container used for loading, storing, and transporting goods. It is typically made of plastic, metal, wood, or composite materials. For example, a logistics box for freight transport, with publication number CN222224819U, allows for stacking by placing the hand on the bottom protective strip along the top edge. When stacking, aligning the bottom support strip with the groove on the upper surface of the mounting cavity allows them to engage, ensuring neat stacking and increasing stability. For large-volume stacking, manually adjusting the handle to a horizontal position, combined with a spring, allows the limit pin to insert into the connection hole of adjacent logistics boxes, ensuring stacking stability. This is the method of using this logistics box for freight transport.

[0003] However, when multiple boxes are tightly packed together, the gaps on the sides are small, making it difficult for operators to reach in and operate the adjustment handles. Even if they can operate them, it may take more time and effort to adjust the position of the handles, reducing work efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a logistics box for logistics and freight.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a logistics box for freight transportation, comprising a box body and a box cover, wherein the box cover has a cavity inside and through grooves communicating with the cavity on both wide sides of the box cover; a recessed groove is formed on the upper surface of the box cover above each through groove; a slider extending into the through groove is slidably installed on one side of the bottom of the recessed groove; an external spring rod is provided between one side of the slider and the inner wall of the recessed groove; an insert rod is sleeved on the surface of the slider and slidably connected to the inside of the through groove; a gear shaft is rotatably connected to the bottom edge of the slider; a rack groove is formed at the bottom of the insert rod that meshes with the end of the gear shaft and is perpendicular to the width direction of the box cover; a slot for inserting the insert rod is formed on one side of the through groove wall; one end of the insert rod extends into the cavity and is sleeved on the bottom of the cavity.

[0006] Preferably, the external spring rod is distributed parallel to the width direction of the lid.

[0007] Preferably, the gear shaft extends upward and is rotatably connected to the bottom edge of the slider.

[0008] Preferably, inserts are inserted into the cavity near the long sides of both sides of the lid, and the two inserts are respectively connected to two grooves on the upper surface of the lid and used to connect with the support strips of the bottom of the box.

[0009] Preferably, an internal spring rod is provided between the bottom of the cavity and the two inserts, and the internal spring rod is arranged parallel to the width direction of the box cover.

[0010] Preferably, the top of the cavity has two slots parallel to the width direction of the box cover. The two slots are symmetrically distributed and a handle is inserted into the slot. The bottom ends of the handle are hinged to the two plug-in arms.

[0011] Preferably, two electric push rods are fixedly installed at the bottom of the cavity. The two electric push rods are distributed close to the two slots and fixedly connected to the bottom edge of the handle. Several blocks for abutting the opposite end faces of the two plugs are fixedly installed at the bottom of the cavity.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a recessed groove and a through groove, the sliding block set in the recessed groove moves and the gear shaft set in the sliding block meshes with the rack groove, so that the insertion rod can move along the through groove, which facilitates the insertion rod entering and exiting the through groove. The insertion rod entering the through groove will not affect the side fit of the two adjacent box covers, and the insertion rod extending out of the through groove can easily enter the slot in the through groove of the adjacent box cover, so that the relative position of the two adjacent box covers in the horizontal direction can be fixed. Because the recessed groove is located on the upper surface of the box cover, it is convenient for personnel to operate.

[0014] 2. In this utility model, the handle is lowered by retracting the electric push rod. Under the hinge action of the two connecting arms, the two plugs are pushed to overcome the tension of the internal spring rod and move away from each other, so that the plugs can pass through the support strip located in the groove on the box cover, which facilitates the fixation of the relative positions of the upper and lower boxes in the vertical, front-back and left-right directions.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figures 1-5 As shown, a logistics box for freight transport includes a box body 1 and a box cover 2. The box cover 2 has a cavity 6 inside, and through grooves 10 communicating with the cavity 6 are opened on both wide sides of the box cover 2. A recessed groove 9 is opened on the upper surface of the box cover 2 above each through groove 10. A slider 15 extending into the through groove 10 is slidably installed on one side of the bottom of the recessed groove 9. An external spring rod 14 is provided between one side of the slider 15 and the inner wall of the recessed groove 9. The external spring rod 14 is distributed parallel to the width direction of the box cover 2. Under normal circumstances, under the pushing action of the external spring rod 14, the slider 15 is in a position where Figure 1 The rear side of the middle settling tank 9 is moved forward by moving the slider 15 to overcome the thrust of the external spring rod 14;

[0024] A rod 8 is fitted onto the surface of the slider 15 and slidably connected to the inside of the through groove 10. A gear shaft 16 is rotatably connected to the bottom edge of the slider 15. The shaft of the gear shaft 16 extends upward and rotatably connects to the bottom edge of the slider 15. A rack groove 17 is formed at the bottom of the rod 8, which meshes with the end of the gear shaft 16 and is perpendicular to the width direction of the cover 2. A slot 13 for inserting the rod 8 is formed on one side wall of the through groove 10. One end of the rod 8 extends into the cavity 6 and is fitted onto the bottom of the cavity 6. Figure 1In the state shown, the lids 2 of two adjacent boxes 1 in the horizontal position are fitted together, and the insert rod 8 protruding from one of the lids 2 is inserted into the through groove 10 of the other lid 2 and into the slot 13 in the groove. The relative position of the gear shaft 16 and the slider 15 is fixed by the pin, and the block prevents the gear shaft 16 from rotating. Therefore, it is easy to fix the position of the insert rod 8 and prevent the insert rod 8 from moving. Thus, it is easy to fix the relative position of the two adjacent lids 2 in the horizontal direction in terms of vertical and vertical arrangement. When separating, simply move the slider 15 to make the slider 15 drive the insert rod 8 to move backward and disengage from the slot 13 on the other lid 2. Then, pull out the pin and rotate the gear shaft 16 to realize the meshing connection of the rack groove 17 to drive the insert rod 8 to move into the cavity 6, so that it can disengage from the through groove 10 on the other lid 2. This makes it convenient for personnel to move the box 1.

[0025] In addition, the pin used in this solution passes through the edge of the gear shaft 16 and the upper surface of the slider 15 to achieve position fixation.

[0026] Inside the cavity 6, near the long sides of the lid 2, two inserts 11 are inserted. Each insert 11 communicates with a groove on the upper surface of the lid 2 and is used to connect with the support strip at the bottom of the box body 1. An internal spring rod 12 is provided between the bottom of the cavity 6 and the two inserts 11. The internal spring rod 12 is parallel to the width direction of the lid 2. Under normal circumstances, the internal spring rod 12 keeps the inserts 11 in a certain position. Figure 4 The state shown indicates that the plug-in 11 does not enter the groove on the lid 2, and when the upper and lower boxes 1 are stacked, the support strip at the bottom of the upper box 1 inserts into the groove on the lid 2 of the lower box 1. Furthermore, the support strip and groove mentioned in this solution are already disclosed in the prior art, and the distribution positions of the support strip and groove in this solution are... Figure 2 and Figure 1 As already shown in the diagram; the top of cavity 6 has two slots 7 parallel to the width direction of the cover 2, the two slots 7 are symmetrically distributed and a handle 3 is inserted into each slot 7, the bottom ends of the handle 3 are hinged to the two plug-in 11, and two electric push rods 4 are fixedly installed at the bottom of cavity 6, the electric push rods 4 can be any model commonly available on the market; the two electric push rods 4 are respectively distributed near the two slots 7 and fixedly connected to the bottom of the handle 3, and several stops 18 are fixedly installed at the bottom of cavity 6 to abut the opposite end faces of the two plug-in 11. Under normal circumstances, the protruding handle 3 makes it convenient for personnel to move the box 1, and when the two boxes 1 are stacked, the electric push rod 4 is retracted to make the handle 3 lower, and under the hinge action of the two connecting arms 5, the two plug-in 11 are pushed to overcome the tension of the internal spring rod 12 and move away from each other, so that the plug-in 11 can pass through the support strip located in the groove on the cover 2, so as to fix the relative position of the two boxes 1 in the vertical, front-back and left-right directions. The additional stops 18 can prevent the two plug-in 11 from moving away from each other. Figure 4When the two plugs 11 are close to each other, that is, when the box 1 is lifted by the handle 3, the two plugs 11 can be prevented from getting close to each other by the connecting arm 5, thereby fixing the position of the handle 3.

[0027] The method of using this utility model is as follows: When stacking the boxes 1, the upper and lower boxes 1 are initially fixed in position by the insertion of the support bars and the grooves. Then, the electric push rod 4 retracts to lower the handle 3. Under the hinge action of the two connecting arms 5, the two plugs 11 are pushed to overcome the tension of the internal spring rod 12 and move away from each other, so that the plugs 11 pass through the support bars located in the grooves on the box cover 2. When stacking the boxes 1 in the horizontal direction, first move the slider 15 to make the slider 15 drive the plug rod 8 to move backward. Then, pull out the pin and rotate the gear. Shaft 16, the rack groove 17 that achieves meshing connection drives the insert rod 8 into the cavity 6 until it is completely housed in the through groove 10, so that the box cover 2 can fit with the side of the adjacent box cover 2. After fitting, the pin is pulled out and the rack groove 17 that achieves meshing connection drives the insert rod 8 into the through groove 10 in the adjacent box cover 2. Then, under the pushing action of the external spring rod 14, the insert rod 8 is inserted into the slot 13 of the through groove 10 in the adjacent box cover 2, and the relative position of the gear shaft 16 and the slider 15 is fixed by the pin.
