DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are 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 creative work are within the scope of protection of the present invention.

Thus, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0021] In the description of the present invention, it should be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "horizontal, vertical, vertical, horizontal" and "top, bottom" are usually based on Figure 1The orientation and position of a transport box shown in a normal placement are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention; the directional words "inside and outside" refer to the inside and outside relative to the contour of each component itself.

[0022] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0023] The present invention provides a transport box, see Figure 1 , including: a box body 100, including a rotatable door 110 and a movable door 120; a telescopic assembly 200, installed at the bottom of the box body 100, including a plurality of telescopic parts 210 and a transmission part 220, the telescopic parts 210 are fixedly connected to the movable door 120, and the telescopic parts 210 are transmission-connected to the transmission part 220; a lane changing mechanism 300, installed at the bottom of the box body 100, and used to drive the telescopic assembly 200.

[0024] In this design, the telescopic assembly 200 includes a plurality of telescopic members 210, and the transport box includes a movable door 120, which is fixedly connected to the telescopic member 210. The telescopic member 210 can be moved by the telescopic member 210. When the transport box needs to carry goods, the telescopic member 210 is extended, and the movable door 120 in the transport box is away from the rotatable door 110. The extended telescopic member 210 can be used to carry more goods, thereby improving transportation efficiency. In addition, the telescopic member 210 can play a role similar to a forklift, and the goods are forked onto the telescopic member 210, without the need for personnel to manually carry the goods onto the telescopic member 210. When the goods in the transport box and the telescopic member 210 need to be unloaded, the goods on the telescopic member 210 are bound by a fixing device (such as a traction guide wheel group and a traction rope, etc.) near the top of the carrying frame body, and the goods on the telescopic member 210 can be automatically detached from the telescopic member 210 by contracting the telescopic member 210. At the same time, the rotatable door 110 of the transport box can also be opened. When the telescopic member 210 contracts, the movable door 120 follows the contracting member to move toward one end close to the rotatable door 110, pushing out the goods in the transport box, thereby unloading the goods in the transport box. The degree of automation is high, which can reduce the labor intensity of the operator.

[0025] In one embodiment, see Figure 1-Figure 2,,The lane changing mechanism 300 includes a first driving unit 310, a second driving unit 320 and a driving shaft 330; the first driving unit 310 is used to apply power to the transmission member 220 to control the extension or retraction of the telescopic member 210; the driving shaft 330 includes a first state and a second state, the second driving unit 320 is used to control the driving shaft 330 to switch between the first state and the second state, the driving shaft 330 is simultaneously connected to the telescopic member 210 and the rotatable door 110 in the first state, and the driving shaft 330 is separated from the telescopic member 210 in the second state.

[0026] The lane changing mechanism 300 includes a first driving unit 310, a second driving unit 320 and a driving shaft 330. The first driving unit 310 is used to apply power to the transmission member 220 to control the extension or retraction of the telescopic member 210, and the second driving unit 320 is used to switch the state of the driving shaft 330. When the driving shaft 330 is in the first state, the driving shaft 330 is simultaneously connected to the telescopic member 210 and the rotatable door 110. That is, when the telescopic member 210 is retracted, the power can be transmitted to the rotatable door 110 through the driving shaft 330 to drive the rotatable door 110 to rotate and open the rotatable door 110. Or when the telescopic member 210 is extended, the power can be transmitted to the rotatable door 110 through the driving shaft 330 to drive the rotatable door 110 to rotate and close the rotatable door 110, thereby realizing the opening and closing of the rotatable door 110. By controlling the driving shaft 330 to switch between the first state and the second state through the first driving unit 310, excessive rotation of the rotatable door 110 can be avoided, damage to the mechanical structure can be avoided, and reliability can be improved.

[0027] In one embodiment, a movable groove 130 is formed at the bottom of the box body 100 , and the movable door 120 passes through the movable groove 130 and is fixedly connected to a telescopic member 210 disposed at the bottom of the box body 100 .

[0028] When the telescopic member 210 moves, the movable groove 130 can provide a moving space for the movable door 120 .

[0029] In one embodiment, see Figure 3 The telescopic assembly 200 further includes a plurality of moving rail boxes 230, and the moving rail boxes 230 are arranged one by one corresponding to the telescopic member 210. The telescopic member 210 has a rack 211 at the bottom, and the moving rail box 230 has a first transmission gear 231 inside. The transmission member 220 sequentially penetrates the plurality of moving rail boxes 230 and is fixedly connected to the first transmission gear 231 inside the moving rail box 230, and the first transmission gear 231 is meshed with the rack 211 at the bottom of the telescopic member 210.

[0030] In this design, the telescopic member 210 has a rack 211 at the bottom, and the rack 211 is engaged with the first transmission gear 231 to achieve power transmission, and the first transmission gear 231 inside each mobile rail box 230 is fixedly connected to the transmission member 220. By controlling the rotation of the transmission member 220, the first transmission gears 231 inside multiple mobile rail boxes 230 can be controlled to rotate, thereby synchronously controlling multiple telescopic members 210 to extend and retract.

[0031] Exemplarily, the number of the movable rail boxes 230 and the telescopic members 210 is not limited, and may be 2, 3, 4, 5, and so on.

[0032] Exemplarily, a rubber foot pad 232 is fixed to the bottom of the movable rail box 230 to contact with the ground for support. When the transport box is lowered to the ground, the rubber foot pad 232 contacts with the ground for shock absorption and buffering.

[0033] In one embodiment, a rotatable shaft 140 is further provided at the bottom of the box body 100, and the rotatable door 110 is fixedly connected to the rotatable shaft 140 through a connecting ear 111. A rotatable gear 141 is provided on the rotatable shaft 140. By driving the rotatable gear 141 to rotate, the rotatable door 110 can be controlled to rotate.

[0034] In the disclosed embodiment, Figure 3 The first driving unit 310 and the transmission member 220 are also shown.

[0035] Figure 4 This is a schematic diagram of the structure of another transport box provided by an embodiment of the present disclosure. Figure 4 A cross-section of a shipping box.

[0036] Figure 5 This is a schematic diagram of the structure of a second transmission gear 233 provided in an embodiment of the present disclosure. Figure 5 for Figure 4 A partial enlarged view of area A in the middle.

[0037] See also Figure 4-Figure 5 In one embodiment, a second transmission gear 233 is movably provided inside the mobile rail box 230, the second transmission gear 233 is meshed with the telescopic member 210, and the second transmission gear 233 has a clamping hole 234; the driving shaft 330 passes through the plurality of mobile rail boxes 230 in sequence, and the driving shaft 330 passes through the clamping hole 234, the mobile rail box 230 also has a clamping member 331, and the driving shaft 330 is fixedly connected to the clamping members 331 in the plurality of mobile rail boxes 230 respectively; when the driving shaft 330 is in the first state, the clamping member 331 is clamped in the clamping hole 234, and when the driving shaft 330 is in the second state, the clamping member 331 is separated from the clamping hole 234.

[0038] Exemplarily, the clamping member 331 is a gear.

[0039] A clamping member 331 is provided on the driving shaft 330 , and a clamping hole 234 is provided on the second transmission gear 233 . When the clamping member 331 is clamped in the clamping hole 234 , transmission can be realized to convert the movement of the telescopic member 210 into the rotation of the driving shaft 330 , thereby realizing the rotation of the rotatable door 110 .

[0040] See again Figure 1 In one embodiment, the lane changing mechanism 300 further includes a power-on unit (not shown in the figure), which is disposed on a side of the box body 100 having the rotatable door 110. The power-on unit is used to sense whether the rotatable door 110 is closed. When the rotatable door 110 is in a closed state, the power-on unit sends a power-on signal to the second driving unit 320. After receiving the power-on signal, the second driving unit 320 drives the driving shaft 330 to convert to the second state.

[0041] The power-on unit may automatically control the second driving unit 320 to convert the driving shaft 330 to the second state, thereby preventing the rotatable door 110 from over-rotating and improving reliability.

[0042] Exemplarily, the power-on unit is a pressure sensor. When the rotatable door 110 is closed, pressure is applied to the pressure sensor, and the pressure sensor can send a power-on signal to the second driving unit 320 .

[0043] Exemplarily, the second driving unit 320 is an electromagnet device or other mechanical device that can achieve reciprocating transportation.

[0044] In one embodiment, see Figure 6 A plurality of clamping members 331 and a third transmission gear 332 are provided on the driving shaft 330. In the first state of the driving shaft 330, the clamping member 331 is clamped in the clamping hole 234, and the driving shaft 330 can obtain the power of the telescopic member 210; in the second state, the clamping member 331 on the driving shaft 330 is disengaged from the clamping hole 234, and the driving shaft 330 cannot obtain the power of the telescopic member 210.

[0045] When the second driving unit 320 is powered on, the second driving unit 320 can control the driving shaft 330 to extend, and when the second driving unit 320 is powered off, the driving shaft 330 is in a retracted state. By controlling the power on and off of the second driving unit 320, the extension and retraction of the driving shaft 330 can be controlled. When the driving shaft 330 is extended, it is in the first state, and when the driving shaft 330 is retracted, it is in the second state.

[0046] In one embodiment, see Figure 1 , Figure 2 and Figure 7The transport box also includes a limiting assembly 400, including a first connecting rope 410, a movable part 420 and a first limiting part 430; a movable groove 440 is arranged on the side of the telescopic part 210, and the movable part 420 is movably arranged in the movable groove 440. The first limiting part 430 is used to limit the moving range of the movable part 420 in the movable groove 440. A first hanging part 150 is also arranged on the side of the box body 100, one end of the first connecting rope 410 is connected to the movable part 420, and the other end of the first connecting rope 410 is connected to the first hanging part 150.

[0047] The first connecting rope 410 can further ensure the reliability of the telescopic member 210 . When the telescopic member 210 carries goods, the pressure on the telescopic member 210 can be shared by the first connecting rope 410 .

[0048] In one embodiment, the first limiting member 430 includes a limiting spring 431 and a limiting block 432. A limiting hole 212 is opened on the surface of the telescopic member 210 adjacent to the movable groove 440. One end of the limiting spring 431 is fixedly arranged in the limiting hole 212, and the other end is fixedly connected to the limiting block 432.

[0049] The first limiting member 430 having the above-mentioned structure is provided to ensure the limiting effect of the first limiting member 430 , and at the same time, to ensure that the movable member 420 can be easily taken out.

[0050] In one embodiment, there are multiple first connecting cables 410 , and the lengths of the multiple first connecting cables 410 decrease sequentially.

[0051] In one embodiment, the lengths of the plurality of connecting cables decrease sequentially from the side away from the box body 100 to the side close to the box body 100 . Providing a plurality of first connecting cables 410 can further ensure the reliability of the retractable member 210 .

[0052] In one embodiment, when there are multiple first connecting cables 410 and the lengths of the first connecting cables 410 decrease in sequence, at this time, the connection positions of the multiple first connecting cables 410 on the telescopic member 210 are different. When the first connecting cable 410 is fixedly connected to the movable member 420 and the first hanging member 150, in order to ensure that the first connecting cable 410 does not affect the telescopic movement of the telescopic member 210, it is necessary to determine the length of the shortest first connecting cable 410. The length of the shortest first connecting cable 410 can be determined as follows: a first connecting cable 410 is set, and when the telescopic member 210 is fully retracted, the first connecting cable 410 is just in a taut state, and at this time, the length of the first connecting cable 410 is the minimum length. According to the length of the telescopic member 210 actually set, the setting position of the limit assembly 400, and the setting position of the first hanging member 150, the actual minimum length of the first connecting cable 410 may be different.

[0053] Of course, the above configuration of the first connecting rope 410 is a configuration when the first connecting rope 410 is fixedly connected. If the first connecting rope 410 is configured as a detachable connecting rope, there is no need to determine the minimum length of the first connecting rope 410.

[0054] In one embodiment, see Figure 8 The limiting assembly 400 further includes a second limiting member 450, a second connecting cable 460 and a second hanging member 470; the second limiting member 450 is disposed at one end of the telescopic member 210 away from the movable door 120, the second connecting cable 460 is disposed in the moving groove 440, and one end of the second connecting cable 460 is connected to one side of the second limiting member 450, and the other end of the second connecting cable 460 is connected to the movable member 420; the second hanging member 470 is disposed in the moving groove 440, and the height of the second hanging member 470 is less than or equal to the height of the bottom of the second limiting member 450, and the second connecting cable 460 is located at the bottom of the second hanging member 470; The size of the second limit member 450 in the first direction 480 is greater than the size of the second limit member 450 in the second direction 490, and the second limit member 450 has a third state and a fourth state; in the third state, the first direction 480 of the second limit member 450 is parallel to the surface of the telescopic member 210, and the second direction 490 is perpendicular to the surface of the telescopic member 210; in the fourth state, the first direction 480 is perpendicular to the surface of the telescopic member 210, and the second direction 490 is parallel to the surface of the telescopic member 210; when the second connecting rope 460 applies tension to the second limit member 450, the second limit member 450 switches from the third state to the fourth state.

[0055] The second limiting member 450 is rotatably disposed in the receiving groove 213 on the telescopic member 210 . The second limiting member 450 is a right-angle limiting plate. Of course, the second limiting member 450 may also be a limiting member of other shapes.

[0056] In one embodiment, the second limiting member 450, the second connecting cable 460 and the second hanging member 470 are provided to achieve the limiting effect of the goods on the telescopic member 210. When the telescopic member 210 is extended to the moving length, the first connecting cable 410 applies a pulling force to the movable member 420, and the movable member 420 applies a pulling force to the second connecting cable 460, driving the second limiting member 450 to switch to the fourth state, thereby achieving the limiting effect on the goods.

[0057] The specific method of use is as follows: 1. Drive the telescopic component 200 to extend the telescopic member 210, and control the first drive unit 310 to drive the telescopic member 210 to extend through the console. In the process of controlling the first drive unit 310 to drive the telescopic member 210 to extend, if the rotatable door 110 is in an open state (such as a horizontal state), the second drive unit 320 can be controlled to switch the drive shaft 330 to the first state. At this time, in the process of extending the telescopic member 210, the rotatable door 110 can obtain the power when the telescopic member 210 is extended, and rotate with the extension of the telescopic member 210. When the rotatable door 110 contacts the side of the box body 100 (that is, when the rotatable door 110 is in a closed state), the power-on unit senses that the rotatable door 110 is closed (the power-on unit (such as a pressure sensor) senses the pressure of the rotatable door 110), thereby energizing the second drive unit 320, and converting the drive shaft 330 from the first state to the second state. After the drive shaft 330 is converted to the second state, the drive shaft 330 cannot obtain the power transmitted by the telescopic member 210. 2. Place the object to be transported in the box 100 and on the telescopic member 210. When the telescopic member 210 is not extended, the movable door 120 of the box 100 is adjacent to the rotatable door 110. When carrying the object to be transported, the telescopic member 210 can be extended first, so that the movable door 120 is away from the rotatable door 110, so as to form a storage space between the movable door 120 and the rotatable door 110. When the telescopic member 210 is extended, the telescopic member 210 can also be used as a forklift to fork the object to be transported onto the telescopic member 210. After the telescopic member 210 is fully extended, the movable door 120 moves to the side of the box 100 away from the rotatable door 110, and then other objects to be transported can be transported into the box 100. At the same time, when the telescopic member 210 is extended, the first connecting rope 410 will pull the movable member 420 until the movable member 420 is stuck at the first limit member 430. When the first connecting rope 410 pulls the movable member 420, since the other end of the movable member 420 is connected to the second connecting rope 460, the second connecting rope 460 will pull the second limiting member 450. After the telescopic member 210 is fully extended, the first connecting rope 410 in the limiting assembly 400 will be in a tense state, and the second limiting member 450 will be converted to the fourth state, which will limit the cargo on the telescopic member 210. At the same time, due to the gravity of the cargo itself, the first connecting rope 410 and the second connecting rope 460 will continue to be in a tense state during the transportation of the cargo. Therefore, the second limiting member 450 can continue to obtain the pulling force applied by the first connecting rope 410 and the second connecting rope 460, ensuring the limiting effect of the second limiting member 450.When the cargo on the telescopic member 210 needs to be unloaded, the telescopic member 210 contracts, the first connecting rope 410 and the second connecting rope 460 gradually change from a taut state to a non-taut state, and the tension on the second stopper 450 gradually decreases, so that when the cargo is pulled off the telescopic member 210, the second stopper 450 will not block the cargo. 3. Move the transport box to the platform of the building, control the telescopic member 210 to retract, unload the object to be transported from the box body 100 and the telescopic member 210, and manually open the rotatable door 110. After the rotatable door 110 rotates, it contacts the platform of the building, so that the rotatable door 110 can serve as a guide plate between the box body 100 and the platform of the building. Then, the object to be transported on the telescopic member 210 is bound to a fixed device on the building (such as a traction guide wheel set and a traction rope, etc.), and the telescopic member 210 is retracted. The object to be transported on the telescopic member 210 will be moved to the fixed device and then moved to the building through the fixed device. The object to be transported in the box 100 will be pushed out by the movable door 120 and moved to the building along the rotatable door 110.
