[0001] The utility model relates to the technical field of transport box unloading, in particular to a transport box provided with an auxiliary unloading mechanism for logistics cargo transportation. Background Art

[0002] Logistics cargo transport boxes mainly include cargo containers, plastic logistics boxes, wooden boxes and containers. They can load a large number of goods into a special container and realize "door-to-door" transportation directly from the shipper's warehouse to the consignee's warehouse. However, when loading and unloading goods, it is easy to cause inconvenience in handling due to the weight and volume of the goods.

[0003] Therefore, a transport box with an auxiliary unloading mechanism for international logistics cargo transportation in the prior art is disclosed as CN215945559U. The cargo is placed on a cart, and the cart is driven to move into the inner cavity of the box by driving the screw to rotate. The two clamping plates are manually rotated away from each other so that the cargo is located between the two clamping plates. The worm rotates to drive the winch roller to rotate and wrap the pull rope. The pull rope then drives one end of the supporting rod to rotate upward through the hook and the hanging ring, and the vertical section of the clamping rod drives the clamping plates to move toward each other to clamp the cargo, thereby realizing the lifting, transportation and stacking of the cargo.

[0004] However, when the prior art is used, since the motor, worm, hoisting roller and other structures are installed in the box, a part of the space in the box is occupied, and the manufacturing cost of the transport box is increased to a certain extent. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art and to propose a transport box provided with an auxiliary unloading mechanism for logistics cargo transportation.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a transport box with an auxiliary unloading mechanism for logistics cargo transportation, including a frame part and a lifting part: the frame part is mainly composed of two support rods installed along the length direction of the transport box and a slide arranged along the width direction of the transport box and sliding between the two support rods. The lifting part is mainly composed of a lifting box and a plurality of winding wheels slidably connected to the slide. The top and bottom of the lifting box are provided with mounting rails, and the mounting rails are plugged into the lifting box, and the pulley group is composed of a plurality of pulleys. The mounting rails at the top of the box are fixedly installed, the mounting rails at the bottom of the box are plugged into the lifting box, and the bottom edge is fixedly connected to a lifting rope extending outside the lifting box. The plurality of winding wheels are distributed in a ring array and are installed at the bottom end of the lifting rope. The outside of the lifting box is rotatably connected to a winding drum, and the connecting wire wound on the winding drum extends into the lifting box and passes through the pulleys on the two pulley groups in turn.

[0007] Preferably, both ends of the support rod are threadedly connected to a threaded barrel, and the outer wall of the threaded barrel is plugged with a fixing seat for fixing inside the transport box.

[0008] Preferably, an extension frame is inserted into one side of the slide, and opposite ends of the slide and the extension frame are both snap-fitted to the surface of the support rod.

[0009] Preferably, one end of the connecting line wound on the winding wheel is fixedly connected to an insert block for fixing the bottom edges of the goods.

[0010] Preferably, both sides of the pulley frame in the pulley group are connected to cards through embedded and rotatable retaining springs, and a pressing block is provided through one side. One end of the card is used to be plugged into the surface of the mounting rail, and the other side is connected to the pressing block by a connecting rope provided through the pulley frame.

[0011] Preferably, one side of the winding reel is fixedly connected to a gear group that is rotatably connected to the lifting box. The gear group is mainly composed of several spur gears of different sizes.

The driving gear is driven by a motor, and the motor is installed at the telescopic end of the electric telescopic rod.

[0013] Compared with the prior art, the advantages and positive effects of the present invention are:

[0014] 1. In the present invention, the fixing seat is installed at the corner of the transport box frame by welding or bolts. When installing the support rod, the support rod is placed between the two fixing seats, and the threaded cylinder is rotated until the threaded cylinder slides and is inserted into the fixing seat to achieve the position installation of the support rod, and then the slide and extension frame are installed. Therefore, the support rod, slide, extension frame and lifting box of this scheme are detachable from the transport box, so they will not take up the space of the transport box, and the support rod, slide, extension frame and lifting box can be recycled, which is beneficial to reduce the cost of the transport box.

[0015] 2. In the utility model, a slider is used to drive the driving gear to move to the vicinity of the corresponding spur gear, and then the electric telescopic rod is extended to enable the driving gear to rise to engage with the corresponding spur gear. By engaging with spur gears of different diameters, the speed ratio of the driving gear and the cable reel is adjusted, which is convenient for using more pulleys. The cable reel needs to release and reel a longer length of connecting wire. Therefore, by adjusting the speed ratio, the cable reel can quickly reel and release the connecting wire, thereby realizing the lifting and lowering of the goods. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0025] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

The two ends of the support rod 1 are threadedly connected with a threaded cylinder 2, and the outer wall of the threaded cylinder 2 is plugged with a fixing seat 3 for fixing inside the transport box. The fixing seat 3 is installed at the corner of the transport box frame by welding or bolts. When installing the support rod 1, the support rod 1 is placed between the two fixing seats 3, and the threaded cylinder 2 is rotated until the threaded cylinder 2 is inserted into the fixing seat 3 when sliding, so as to realize the position installation of the support rod 1. An extension frame 6 is inserted on one side of the slide 5, and the opposite ends of the slide 5 and the extension frame 6 are both clamped with the surface of the support rod 1, as shown in FIG. Figure 1 and Figure 2 As shown, the opposite ends of the slide 5 and the extension frame 6 are rotating bodies, and the cross section is H-shaped. Therefore, after the two support rods 1 are fixed in position, the slide 5 and the extension frame 6 can be installed by placing the ends on the support rods 1, and the slide 5 and the extension frame 6 can slide on the surface of the support rods 1 along the length direction of the transport box:

[0027] The lifting part is mainly composed of a lifting box 4 and a plurality of winding wheels 10 that are slidably connected to the slide 5. One end of the connecting line wound on the winding wheel 10 is fixedly connected to an insert block 11 for fixing the bottom edge of the cargo. The insert block 11 is L-shaped, and when facing heavier or larger cargo, after inserting a plurality of insert blocks 11 around the bottom edge of the cargo, a rope is passed through a plurality of insert blocks 11 to achieve a plurality of insert blocks 11 fixedly tied around the cargo, and the winding wheel 10 is rotated to release or reel the internally wound connecting line. To achieve the insertion of the plug block 11 into the bottom edge of the cargo at different heights, mounting rails 12 are provided at the top and bottom of the lifting box 4, and pulley blocks 13 are plugged into the mounting rails 12. The pulley blocks 13 are composed of a plurality of pulleys. The upper pulley block 13 is a fixed pulley, and the lower pulley block 13 is a movable pulley. By adjusting the number of pulleys in the two pulley blocks 13, force saving is achieved. The two sides of the pulley frame in the pulley block 13 are connected to the card 14 through the embedded rotation of the retaining spring, and a pressing block 15 is provided on one side. The card 1 One end of the card 14 is used to be plugged into the surface of the mounting rail 12, and the other end is connected to the pressing block 15 with a connecting rope 16 that runs through the pulley frame body. By plugging one side of the card 14 into the side wall of the mounting rail 12, the pulley is fixed on the mounting rail 12. By pushing the pressing block 15, the other side of the card 14 is swung under the traction of the connecting rope 16, and the card 14 and the mounting rail 12 are dislocated, which makes it easy to slide out the pulley or adjust the position of the pulley on the mounting rail 12, and the mounting rail 12 at the top of the box is fixed. The mounting rails 12 at the bottom of the box are plugged into the lifting box 4, and the bottom edge is fixedly connected to a lifting rope 7 extending outside the lifting box 4. A number of winding wheels 10 are distributed in a ring array and installed at the bottom end of the lifting rope 7. The outside of the lifting box 4 is rotatably connected to a winding drum 9. The connecting wire wound on the winding drum 9 extends into the lifting box 4 and passes through the pulleys on the two pulley blocks 13 in turn. The lifting rope 7 can be lifted and lowered by lifting the pulley block 13 below, and the cargo can be lifted or lowered by using the lifting rope 7. The connecting wire on the winding drum 9 is installed as shown in the figure. Figure 4 As shown, the pulleys on the two pulley sets 13 are passed through in an alternating manner, and Figure 4 As shown, the top of the lifting box 4 is also a rotating body with an H-shaped cross-section, which can be inserted into the slide 5 and the extension frame 6. Therefore, the lifting box 4 is used to lift the goods, and it can slide along the surface of the slide 5, that is, slide along the width direction of the transport box to adjust the position, and the slide 5 is used to slide along the surface of the support rod 1, which can drive the goods to slide along the length direction of the transport box to adjust the position.

[0028] In addition: one side of the winding drum 9 is fixedly connected to a gear set 17 that is rotatably connected to the lifting box 4. The gear set 17 is mainly composed of several spur gears of different sizes. The outer wall of the lifting box 4 is located at the position of the gear set 17 and is rotatably connected to a screw rod 19. A slider 18 is threadedly connected to the screw rod 19. The surface of the slider 18 is embedded with an electric telescopic rod 8, and the slider 18 is rotatably connected to a drive gear 20 for meshing with the spur gear on the gear set 17. The drive gear 20 is driven by a motor, and the motor is installed at the telescopic end of the electric telescopic rod 8. In this solution, the screw rod 19 is also driven by installing a motor, and as shown in FIG. Figure 7 As shown, the distribution position of several gears on the gear set 17 is conical, and the length direction of the screw rod 19 is parallel to the inclination setting of the surface of the gear set 17. Therefore, the slider 18 can be used to drive the driving gear 20 to move to the vicinity of each spur gear by driving the screw rod 19 by the motor, and then the driving gear 20 can be raised to engage with the corresponding spur gear by extending the electric telescopic rod 8. By engaging with spur gears of different diameters, the speed ratio of the driving gear 20 and the cable reel 9 can be adjusted, which makes it convenient for the cable reel 9 to release and reel a longer length of connecting wire when using more pulleys. Therefore, by adjusting the speed ratio, the cable reel 9 can be quickly reeled and released, thereby realizing the lifting and lowering of the goods.

[0029] Working principle: install two support rods 1 in the transport box, then install the slide 5 and the extension frame 6 between the two support rods 1, and install the lifting box 4 in the slide 5 and the extension frame 6. According to the size or weight of the goods, rotate the winding wheel 10 to adjust the distance between the plug block 11 and the lifting rope 7, and adjust the number of pulleys of the pulley group 13 on the mounting rail 12. At the same time, adjust the position of the driving gear 20 according to the number of pulleys used. When in use, use the plug block 11 to bind and fix the bottom edge of the goods, use the winding drum 9 to rotate and reel the connecting line to realize the rise of the pulley group 13 below, and under the action of the lifting rope 7, realize several plug blocks 11 to lift the goods, use the sliding of the lifting box 4 and the sliding of the slide 5 to realize the transport of the lifted goods into the transport box, or move the goods in the transport box out to realize unloading of the transport box.
