However, the position of the pallet is relatively low, which is inconvenient when placing materials on the pallet or taking materials off the pallet.

[0040] Based on this, the embodiment of the present application provides a material transportation device, which is connected to the vehicle body through a flipping member so that the flipping member can rotate relative to the vehicle body, and the storage plate and the flipping member are connected through a lifting assembly so that when the flipping member rotates relative to the vehicle body, the storage plate can be lifted or lowered relative to the vehicle body, thereby adjusting the height of the storage plate relative to the vehicle body. The limiting assembly slides relative to the flipping member so that the flipping member is located in a fixed position or a rotating position, thereby fixing the flipping member at the current position, or rotating the flipping member relative to the vehicle body, thereby fixing the storage plate at the current position, or lifting or lowering the storage plate relative to the vehicle body. Thus, when unloading materials from the storage plate or placing materials on the storage plate, the storage plate can be lifted to adjust the height of the storage plate, thereby bringing the storage plate close to the materials or the platform where the materials need to be placed, and placing the materials on the storage plate or unloading the materials onto the platform is more labor-saving and convenient.

[0041] The following describes the embodiments of the present utility model in conjunction with the accompanying drawings.

[0042] Reference Figures 1 to 5 As shown, an embodiment of the present application provides a material transport device, including: a vehicle body 100, a flip member 300, a lifting assembly 400 and a limiting assembly 500, and a storage plate 200 is arranged on the vehicle body 100.

[0043] The flip member 300 is rotatably connected to the vehicle body 100 , and the flip member 300 is connected to the storage plate 200 via a lifting assembly 400 . The flip member 300 is configured to rotate relative to the vehicle body 100 to lift or lower the storage plate 200 relative to the vehicle body 100 via the lifting assembly 400 .

[0044] The limit assembly 500 is slidably disposed on the flip member 300, and the limit assembly 500 slides relative to the flip member 300 to switch the flip member 300 between a fixed position and a rotating position. When in the fixed position, the flip member 300 is fixed at the current position, and when in the rotating position, the flip member 300 rotates relative to the vehicle body 100.

[0045] The storage plate 200 is used for placing supplies.

[0046] In some embodiments, the storage plate 200 is rectangular in shape, and has four elastic gaskets 220 on the storage plate 200 . The four elastic gaskets 220 are respectively disposed at the four corners of the storage plate 200 .

[0047] Specifically, at least two wheels 130 are also provided on the vehicle body 100, and a fixing plate 131 is provided on the wheel 130, and the fixing plate 131 is connected to the wheel 130, and the fixing plate 131 is connected to the vehicle body 100. Exemplarily, the number of wheels 130 is four, wherein the two wheels 130 on the side close to the flip member 300 are provided with brakes, and the wheels 130 are controlled to roll or stop rolling by the brakes, thereby controlling the transport device to move or stop moving; the two wheels 130 on the side away from the flip member 300 are universal wheels, so that the wheels 130 can roll in different directions, thereby allowing the transport device to move in multiple directions. In some embodiments, a hydraulic lifting member is provided on the wheel 130, so that the vehicle body 100 and the storage plate 200 can rise or fall at the same time.

[0048] In a specific implementation, the position limiting assembly 500 is slid relative to the flip member 300 so that the flip member 300 is located at the rotation position. At this time, the flip member 300 can be rotated relative to the vehicle body 100, and the lifting assembly 400 connects the flip member 300 and the storage plate 200, so that the flip member 300 can drive the storage plate 200 to be lifted or lowered relative to the vehicle body 100 through the lifting assembly 400, thereby changing the height of the storage plate 200 relative to the vehicle body 100. After the storage plate 200 is lifted or lowered to a desired position, the position limiting assembly 500 is slid relative to the flip member 300 so that the flip member 300 is located at a fixed position, thereby fixing the flip member 300 at the current position, thereby fixing the storage plate 200 at the current position.

[0049] In some embodiments, at least one pedal part 120 is provided on the vehicle body 100, and the pedal part 120 is located below the flip member 300. When operating the transport device, the operator steps on the pedal part 120 to rotate the flip member 300 relative to the vehicle body 100, thereby driving the flip member 300 to rotate relative to the vehicle body 100 is more convenient and labor-saving. The exemplary number of the pedal parts 120 is two, and the two pedal parts 120 are respectively located on both sides of the flip member 300.

[0050] The material transport device provided in the embodiment of the present application is connected to the vehicle body 100 by a flip member 300, so that the flip member 300 can rotate relative to the vehicle body 100, and the storage plate 200 is connected to the flip member 300 by a lifting assembly 400, so that when the flip member 300 rotates relative to the vehicle body 100, the storage plate 200 can be lifted or lowered relative to the vehicle body 100, thereby adjusting the height of the storage plate 200 relative to the vehicle body. The limit assembly 500 slides relative to the flip member 300, so that the flip member 300 is located at a fixed position or a rotating position, thereby fixing the flip member 300 at the current position, or rotating the flip member 300 relative to the vehicle body 100, thereby fixing the storage plate 200 at the current position, or lifting or lowering the storage plate 200 relative to the vehicle body 100. Therefore, when unloading materials from the storage board 200 or placing materials on the storage board 200, the storage board 200 can be lifted to adjust the height of the storage board 200, so that the storage board 200 is close to the materials or the platform where the materials need to be placed, and it is more labor-saving and convenient to place the materials on the storage board 200 or unload the materials onto the platform.

[0051] Reference Figure 3 and Figure 4 As shown, in some embodiments, the lifting assembly 400 includes a connecting arm 410 , which connects the flip member 300 and the storage plate 200 , and the connecting arm 410 is rotationally connected to at least one of the flip member 300 or the storage plate 200 .

[0052] The connecting arm 410 is rotatably connected to at least one of the flip member 300 and the storage plate 200, so that when the flip member 300 drives the storage plate 200 to rise or fall relative to the vehicle body 100 through the connecting arm 410, the storage plate 200 is relatively horizontal, thereby preventing the storage plate 200 from tilting significantly and causing the goods to fall. Exemplarily, the connecting arm 410 is rotatably connected to both the flip member 300 and the storage plate 200.

[0053] Specifically, the flip member 300 is rotatably connected to one side of the vehicle body 100. When the flip member 300 rotates toward the side away from the vehicle body 100, the flip member 300 drives the storage plate 200 to be lifted through the connecting arm 410. When the flip member 300 rotates toward the vehicle body 100, the flip member 300 drives the storage plate 200 to be lowered through the connecting arm 410. In this way, when operating the transport device, the operator can put his hand on the flip member 300, and by controlling the flip member 300 to rotate relative to the vehicle body 100, the storage plate 200 can be lifted or lowered relative to the vehicle body 100, which is relatively simple and convenient to operate.

[0054] In some embodiments, when the flip member 300 is perpendicular to the vehicle body 100, the storage plate 200 is located on the vehicle body 100 and abuts against the vehicle body 100. When using the transportation device, the flip member 300 is rotated toward the side away from the vehicle body 100 so that the angle between the flip member 300 and the vehicle body 100 is an obtuse angle. At this time, it is easier for the operator to pull the flip member 300.

[0055] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the lifting assembly 400 also includes at least one lifting rod 420 and at least one mounting member 430, the mounting member 430 is fixedly connected to the storage plate 200, the lifting rod 420 is inserted into the connecting arm 410 and the mounting member 430, and the connecting arm 410 drives the storage plate 200 to be lifted or lowered relative to the vehicle body 100 through the lifting rod 420 and the mounting member 430.

[0056] The top surface of the storage plate 200 is a bearing surface for placing materials, and the mounting member 430 is located below the storage plate 200 and connected to the bottom surface of the storage plate 200. The lifting rod 420 is disposed below the storage plate 200. The vehicle body 100 is in a rectangular frame shape, and when the storage plate 200 abuts against the vehicle body 100, the lifting rod 420 and the mounting member 430 are both located in the vehicle body 100.

[0057] Exemplarily, the lifting rod 420 is perpendicular to the flip member 300 , the number of the mounting member 430 is one, and the mounting member 430 is perpendicular to the lifting rod 420 .

[0058] Specifically, the flip member 300 rotates relative to the vehicle body 100 to drive the lifting rod 420 to rise or fall through the connecting arm 410. The mounting member 430 connects the storage plate 200 and the lifting rod 420, and the storage plate 200 can be lifted or lowered through the mounting member 430.

[0059] Reference Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments, the lifting assembly 400 also includes at least one limiting rod 440 and at least one connecting member 450, the limiting rod 440 is connected to the vehicle body 100, the connecting member 450 connects the limiting rod 440 and the lifting rod 420, and the lifting rod 420 rotates around the limiting rod 440 to drive the storage plate 200 to be lifted or lowered relative to the vehicle body 100.

[0060] Specifically, the lifting rod 420 and the limiting rod 440 corresponding to the lifting rod 420 are connected by the connecting member 450, so that when the flip member 300 drives the connecting arm 410 to move, the connecting arm 410 drives the lifting rod 420 to rotate around the limiting rod 440, thereby driving the storage plate 200 to rise or fall horizontally. At the same time, the connecting member 450 can limit the distance between the lifting rod 420 and the corresponding limiting rod 440, that is, the rotation radius of the lifting rod 420, thereby limiting the height of the storage plate 200 relative to the vehicle body 100.

[0061] It should be noted that the limiting rod 440 is rotatably connected to at least one of the vehicle body 100 and the connecting member 450 , so that the lifting rod 420 can rotate around the limiting rod 440 .

[0062] Exemplarily, the lifting rod 420 is parallel to the limiting rod 440, and the number of the lifting rod 420 and the limiting rod 440 are both two, and both ends of the limiting rod 440 are connected to the inner side of the vehicle body 100. The number of the connecting members 450 is four, and the connecting members 450 are connected to the ends of the lifting rod 420, and the limiting rod 440 is inserted into the connecting members 450.

[0063] In a specific implementation, the number of the lifting rods 420 is at least two, and the two lifting rods 420 are arranged below the storage plate 200 at an interval.

[0064] The mounting member 430 connects the lifting rods 420, wherein one lifting rod 420 is connected to the connecting arm 410, so that the connecting arm 410 can drive the lifting rod 420 to rise or fall. By providing at least two lifting rods 420 and at least one mounting member 430, the lifting rods 420 are arranged below the storage board 200 at intervals, and the mounting member 430 connects the lifting rods 420, so that the lifting rods 420 can rise or fall synchronously, and the lifting rods 420 drive the storage board 200 to rise or fall through the mounting member 430, so that the storage board 200 can rise or fall more smoothly.

[0065] There are at least two limit rods 440, and there are at least two connecting pieces 450. Each lifting rod 420 corresponds to each limit rod 440 one by one. The lifting rod 420 is connected to the corresponding limit rod 440 through the connecting piece 450. The distances between each lifting rod 420 and the corresponding limit rod 440 are the same, so that the angles of rotation of each lifting rod 420 around the corresponding limit rod 440 are the same, and the heights of rising or falling of each lifting rod 420 relative to the vehicle body 100 are the same, thereby ensuring the stability of the rising or falling of the storage plate 200, and preventing the storage plate 200 from tilting when rising or falling, which may cause the materials placed on the storage plate 200 to fall off.

[0066] Specifically, a connection plate 210 is provided on the bottom surface of the storage plate 200, and a connection hole 211 is provided on the connection plate 210, and the lifting rod 420 is inserted into the connection hole 211. By providing the connection plate 210, the stability of the connection between the lifting rod 420 and the storage plate 200 is increased.

[0067] Exemplarily, there are two lifting rods 420 , and four connecting plates 210 . Two connecting plates 210 are connected to one lifting rod 420 , and the connecting holes 211 on the two connecting plates 210 are respectively close to two ends of the lifting rod 420 .

[0068] Reference Figure 3 and Figure 5 As shown, in some embodiments, at least one mounting seat 110 is provided on the vehicle body 100, and the mounting seat 110 has a mounting hole 111, and the inner wall of the mounting hole 111 has a plurality of sequentially spaced clamping grooves 112. The flip member 300 is provided with a connecting seat 310, and the connecting seat 310 has at least one rotating seat 311, and the rotating seat 311 is at least partially located in the mounting hole 111, and the rotating seat 311 has a plug-in groove 313 and a plurality of sequentially spaced access holes 312, and the access holes 312 are provided on the groove wall of the plug-in groove 313.

[0069] The limiting assembly 500 includes a limiting member, which includes a plurality of wedge blocks 510 arranged in sequence and spaced apart from each other. The wedge blocks 510 are located in the insertion grooves 313. The wedge blocks 510 are configured to be engaged with the engaging grooves 112 through the entry and exit holes 312 so that the flipping member 300 is located in a fixed position, or to be disengaged from the engaging grooves 112 so that the flipping member 300 is located in a rotating position.

[0070] The limiting member is located in the inserting groove 313 , and each wedge block 510 corresponds to each access hole 312 one by one. Meanwhile, each wedge block 510 corresponds to each clamping groove 112 one by one.

[0071] Specifically, the wedge block 510 extends out of the insertion slot 313 through the access hole 312 and is partially located in the clamping slot 112. At the same time, the wedge block 510 is partially located in the access hole 312, so that the wedge block 510 is clamped with the clamping slot 112. At this time, the flip member 300 is located in a fixed position, and the rotating seat 311 cannot rotate relative to the mounting hole 111, thereby making the flip member 300 unable to rotate relative to the vehicle body 100. The wedge block 510 returns to the insertion slot 313 through the access hole 312, so that the wedge block 510 is disengaged from the clamping slot 112. At this time, the flip member 300 is located in a rotating position, and the rotating seat 311 can rotate relative to the mounting hole 111, thereby making the flip member 300 rotate relative to the vehicle body 100.

[0072] Reference Figure 3 and Figure 5As shown, in a specific implementation, the limiting assembly 500 also includes a driving member 520, which is at least partially located in the plug-in slot 313. The driving member 520 is configured to slide along the plug-in slot 313 to drive the wedge block 510 to engage with the engaging slot 112 through the entry and exit hole 312, or to disengage from the engaging slot 112.

[0073] By providing the driving member 520, the driving member 520 can slide along the insertion groove 313 to engage or disengage the wedge block 510 with the engaging groove 112, so that the driving wedge block 510 and the engaging groove 112 can be engaged or disengaged relatively simply and conveniently.

[0074] Specifically, the driving member 520 slides along the insertion groove 313 toward the groove bottom of the insertion groove 313, so that the driving member 520 is partially inserted into each wedge block 510, thereby driving each wedge block 510 to move toward the clamping groove 112, so that the wedge block 510 is clamped with the clamping groove 112. The driving member 520 slides along the insertion groove 313 toward the side away from the groove bottom of the insertion groove 313, so that the driving member 520 is disconnected from each wedge block 510, and then the wedge block 510 is returned to the insertion groove 313, so that the wedge block 510 is disconnected from the clamping groove 112.

[0075] Reference Figure 5 As shown, in a specific implementation, the driving member 520 includes a connecting section 521 and an operating section 522 . The connecting section 521 is conical, the small diameter end of the connecting section 521 is connected to the operating section 522 , and the large diameter end of the connecting section 521 is located in the plug-in slot 313 .

[0076] The operating section 522 is located outside the first plug hole 112 , so that an operator can operate the operating section 522 to move, thereby driving the connecting section 521 to slide along the plug slot 313 .

[0077] The large diameter end of the connecting section 521 is located in the plug-in groove 313, and the wedge blocks 510 are arranged at intervals on the side of the connecting section 521 and connected to the side of the connecting section 521. The connecting section 521 slides along the plug-in groove 313 to drive the wedge blocks 510 to move toward the clamping groove 112 through the large diameter end of the connecting section 521.

[0078] Exemplarily, the rotating seat 311 has a baffle 314 with a limiting hole on it, which is connected to the plug-in slot 313 . The diameter of the limiting hole is smaller than the diameter of the large diameter end of the connecting section 521 to prevent the connecting section 521 from detaching from the plug-in slot 313 .

[0079] In a specific implementation, the wedge block 510 has a first magnetic attraction portion, the connecting section 521 has a second magnetic attraction portion, and the first magnetic attraction portion is magnetically connected to the second magnetic attraction portion.

[0080] The first magnetic attraction portion is located on the side of the wedge block 510 away from the clamping groove 112, and the second magnetic attraction portion is located on the outer surface of the connecting section 521. The first magnetic attraction portion is magnetically connected to the second magnetic attraction portion, so that the connecting section 521 slides along the plug-in groove 313, and the first magnetic attraction portion is connected or disconnected with the second magnetic attraction portion, thereby enabling the connecting section to drive the wedge block 510 to move.

[0081] Reference Figure 5 As shown, in some embodiments, the limiting assembly 500 further includes an elastic member 530 , one end of the elastic member 530 is connected to a side of the wedge block 510 away from the driving member 520 , and the other end of the elastic member 530 is connected to the bottom of the insertion slot 313 .

[0082] The elastic member 530 is provided to connect the wedge blocks 510 to ensure the position of the wedge blocks 510 , so that the wedge blocks 510 always correspond to the clamping grooves 112 one by one.

[0083] Specifically, one side of the wedge block 510 is connected to the elastic member 530. When the driving member 520 slides toward the elastic member 530, the driving member 520 drives the other side of the wedge block 510 to move toward the snap-in groove 112. When the driving member 520 slides toward the side away from the elastic member 530 to disconnect from the wedge block 510, the other side of the wedge block 510 moves toward the axis of the plug-in groove 313.
