Description

Technical Field

[0001] This invention relates to the field of manual trolley technology, and in particular to a logistics transport trolley that facilitates loading and unloading of goods. Background Technology

[0002] In logistics, transport trolleys are often used when transporting goods. Transport trolleys are small in size, easy for users to pull, and can transport goods over short distances. However, existing transport trolleys have the following disadvantages:

[0003] 1. When using existing transport trolleys, the height of the goods is limited because the upper support of the trolley cannot be adjusted. When taller goods are placed on the upper layer of the trolley, they will become unstable and shake, or even fall off. At the same time, it will be inconvenient to load and unload goods.

[0004] 2. When using existing transport trolleys, the shelves are fixedly connected and cannot be disassembled for individual use. This causes users to need to find another transport trolley when goods need to be transported in different routes, resulting in inconvenience in goods transportation.

[0005] 3. When using existing transport trolleys, the lack of auxiliary unloading tools often leads to the bottom of the stacked goods being pulled out, causing the goods above to fall down, making unloading very inconvenient. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the shortcomings of the prior art, the present invention provides a logistics transport trolley that facilitates loading and unloading of goods. It solves the technical problem that when goods are stacked at the bottom of existing multi-layer transport trolleys, the height of the upper support of the trolley cannot be adjusted, which limits the height of the goods at the bottom. When taller goods are placed on the upper layer of the trolley, instability and swaying may occur, or even falling off.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A logistics transport trolley for easy loading and unloading of goods includes a first transport trolley, four side support rods are fixedly installed on the upper end of the first transport trolley, and the four side support rods are distributed at the four corners of the first transport trolley. A second transport trolley is installed above the four side support rods, and the second transport trolley can slide outside the four side support rods.

[0011] The second transport trolley has two side slots on both the left and right sides. Each side slot has a shaft sleeve rotatably installed inside it. Each shaft sleeve has a universal wheel rotatably installed at its end. Each universal wheel has a fixing plate fixedly installed at its side end.

[0012] The second transport trolley has four screws threaded through its interior, and each screw is located above the fixing plate. When the fixing plate is in a horizontal position, each screw is inserted into the fixing plate.

[0013] Preferably, a T-shaped groove is provided through the upper ends of both the left and right sides of the first transport trolley, and a support plate is slidably installed inside each T-shaped groove;

[0014] Each of the support plates has a top plate fixedly installed at its upper end, two springs are fixedly installed between the bottom of each T-shaped slide and the top plate, and a fixing collar is fixedly installed on the circumferential surface of each side support rod.

[0015] The second transport trolley is located above four fixing collars, and the fixing collars are used to support the second transport trolley.

[0016] Preferably, an upper slide rail is provided above the second transport trolley, and an inner slider is slidably installed inside the upper slide rail;

[0017] The upper end of the inner slider is fixedly installed with a threaded rod, and the lower end of the second transport trolley is provided with a lower slide rail. The lower slide rail is slidably installed with a first slide plate and a second slide plate.

[0018] Among them, the lower end of the second transport trolley near the opening of the lower slide rail is fixedly installed with two side baffles, and the two side baffles are located on the left and right sides of the lower slide rail. A shaft is rotatably installed between the first slide plate and the second slide plate, and a lower slide wheel is rotatably installed at the lower end of both the first slide plate and the second slide plate.

[0019] Furthermore, the number of sliding wheels under the second skateboard is at least two.

[0020] Preferably, a T-shaped handle is fixedly installed on the side end of the second skateboard;

[0021] The lower end of the first slide is fixedly equipped with a lower clamping plate, which can be clamped between two side baffles. A rotating shaft is fixedly installed on the inner wall of each side groove.

[0022] Each of the shaft sleeves is rotatably sleeved on the outside of the rotating shaft, and each of the shaft sleeves has a semi-circular threaded groove at its side end, and each semi-circular threaded groove can be matched with the screw.

[0023] Preferably, each of the aforementioned axle sleeves and casters is rotatably mounted with a pivot;

[0024] Each fixed plate is horizontally distributed with the rotating shaft, and each fixed plate has a threaded hole through its side end. The upper slide rail is located in the middle of the second transport trolley, and the surface of the threaded rod is fitted with a threaded sleeve through a threaded sleeve.

[0025] A rotating shaft sleeve is rotatably mounted below the threaded sleeve, and a side slide rod is fixedly mounted at the end of the rotating shaft sleeve.

[0026] (III) Beneficial Effects

[0027] First, the second transport trolley moves away from the four side support rods. At the same time, the user can pull out the T-shaped handle at the bottom of the second transport trolley and rotate the four casters downwards to contact the ground. At this time, the second transport trolley becomes an independent trolley. By designing the first and second transport trolleys to be detachable, they can serve as two layers of sorting when not detached. The height of the second transport trolley is also variable, so goods of different heights can be placed on the first transport trolley. When detached, they can function as two independent trolleys, greatly improving the convenience of loading and unloading goods. In addition, the side sliding rods set on the second transport trolley can further improve the convenience of unloading.

[0028] Second, after the top plate is reset, it acts as a barrier to prevent the goods on the first transport trolley from falling off the sides during movement. By setting a movable top plate on the first transport trolley, the goods can slide into the first transport trolley without affecting their movement, and the goods can also be prevented from falling off the first transport trolley, which greatly improves the protection of the goods during transport.

[0029] Third, the goods will come into contact with multiple sliding wheels, which can provide good smoothness and facilitate the goods to enter the first transport trolley. At the same time, the goods can raise the height of the second transport trolley. The second transport trolley moves upward outside the four side support rods. Since the second transport trolley itself is subject to gravity, it can exert a certain squeezing effect on the goods below, which can prevent the goods from sliding during transportation and further improve the stability of the goods transportation.

[0030] 4. After the side slide bar height is adjusted, the user inserts the side slide bar between the two goods. At this time, the user can then take out the goods at the bottom. By setting a side slide bar on the second transport trolley, the side slide bar can be used to provide auxiliary support for the goods, making it easier for the user to pull out the goods at the bottom. At the same time, the height and position of the side slide bar can be adjusted, so that goods in various positions on the second transport trolley can be taken out, which greatly improves the convenience of unloading.

[0031] 5. When the user places the second transport trolley on the ground, with the four casters in contact with the ground, the casters are designed to rotate at an angle. When the second transport trolley is not used independently, the casters will not obstruct the goods on the first transport trolley. At the same time, the multiple casters located on both sides of the second transport trolley can play a certain protective role, preventing the side walls of the second transport trolley from colliding with other objects. When the second transport trolley is in use, it can also play a supporting and sliding role, greatly improving the convenience of transporting goods with the second transport trolley.

[0032] VI. The user can rotate the T-shaped handle upwards, which will cause the second slide plate to rotate. The second slide plate rotates at the end of the first slide plate via the lower rollers. At this time, the second slide plate and the T-shaped handle are combined to form the pull rod of the second transport trolley. By designing the second slide plate and the T-shaped handle to be retractable into the second transport trolley, they do not take up space when not in use. In addition, the lower rollers under the second and first slide plates can also provide a smooth sliding effect, which greatly improves the convenience of using the second transport trolley.

[0043] This application provides a logistics transport trolley that facilitates loading and unloading of goods. It effectively solves the problem that when goods are stacked at the bottom of existing multi-layer transport trolleys, the height of the upper support cannot be adjusted, which limits the height of the goods at the bottom. When taller goods are placed on the upper layer of the trolley, they will become unstable and shake, or even fall off.

[0044] Example

[0045] The technical solution in this application effectively solves the technical problem that when goods are stacked at the bottom of existing multi-layer transport carts, the height of the upper support cannot be adjusted, resulting in a limitation on the height of the goods at the bottom. When taller goods are placed on the upper layer of the cart, instability and swaying may occur, or even the goods may fall off. The overall idea is as follows:

[0046] To address the problems existing in the prior art, the present invention provides a logistics transport trolley that facilitates loading and unloading of goods, including a first transport trolley 1. Four side support rods 12 are fixedly installed on the upper end of the first transport trolley 1, and the four side support rods 12 are distributed at the four corners of the first transport trolley 1. A second transport trolley 2 is installed above the four side support rods 12. The second transport trolley 2 can slide outside the four side support rods 12. By designing the first transport trolley 1 and the second transport trolley 2 to be detachable, they can serve as two layers of classification when not detached, and can serve as two independent trolleys when detached, which greatly improves the convenience of loading and unloading goods. At the same time, the side sliding rods 27 provided on the second transport trolley 2 can further improve the convenience of unloading.

[0047] The second transport trolley 2 has two side slots 29 on both the left and right sides. Each side slot 29 has a shaft sleeve 31 rotatably installed inside. Each shaft sleeve 31 has a universal wheel 34 rotatably installed at its end. Each universal wheel 34 has a fixing plate 35 fixedly installed at its side end.

[0048] The second transport trolley 2 has four screws 28 threaded through its interior, and each screw 28 is located above the fixing plate 35. When the fixing plate 35 is in a horizontal position, each screw 28 is inserted into the fixing plate 35.

[0049] The upper ends of both sides of the first transport trolley 1 are provided with T-shaped grooves 14, and a support plate 16 is slidably installed inside each T-shaped groove 14. A top plate 17 is fixedly installed at the upper end of each support plate 16. Two springs 15 are fixedly installed between the bottom of each T-shaped groove 14 and the top plate 17. A fixing collar 13 is fixedly installed on the circumferential surface of each side support rod 12. The second transport trolley 2 is located above the four fixing collars 13, and the fixing collars 13 are used to support the second transport trolley 2. The top plate 17 moves downward, causing the support plate 16 to move downward inside the T-shaped groove 14. At the same time, the top plate 17 will cause the two springs 15 to compress and deform. When the goods are completely moved onto the first transport trolley 1 and the goods are separated from the top plate 17, the springs 15 will cause the top plate 17 to pop out through the elastic force.

[0050] The second transport trolley 2 has an upper slide rail 22, and an inner slider 23 is slidably installed inside the upper slide rail 22. A threaded rod 26 is fixedly installed at the upper end of the inner slider 23. The lower end of the second transport trolley 2 has a lower slide rail 4, and a first slide plate 42 and a second slide plate 45 are slidably installed inside the lower slide rail 4. Two side baffles 41 are fixedly installed at the lower end of the second transport trolley 2 near the opening of the lower slide rail 4, and the two side baffles 41 are located on the left and right sides of the lower slide rail 4. A shaft 44 is rotatably installed between the first slide plate 42 and the second slide plate 45. A lower slide wheel 46 is rotatably installed at the lower end of both the first slide plate 42 and the second slide plate 45. There are at least two lower slide wheels 46 under the second slide plate 45. When the goods move into the first transport trolley 1, the top of the goods will contact the bottom of the second transport trolley 2, and at the same time, the goods will contact multiple lower slide wheels 46. Multiple lower slide wheels 46 can play a good smoothing role, making it convenient for the goods to enter the first transport trolley 1.

[0051] The second slide plate 45 is fixedly equipped with a T-shaped handle 47 at its side end; the lower end of the first slide plate 42 is fixedly equipped with a lower clamping plate 43, which can be clamped between the two side baffles 41. The inner wall of each side groove 29 is fixedly equipped with a rotating shaft 3; each shaft sleeve 31 is rotatably sleeved on the outside of the rotating shaft 3, and the side end of each shaft sleeve 31 is provided with a semi-circular screw groove 32, and each semi-circular screw groove 32 can cooperate with the screw 28. When the shaft sleeve 31 is rotated ninety degrees, the universal wheel 34 and the shaft sleeve 31 are in a vertical state. At this time, the user rotates the screw 28 downward, and the screw 28 rotates downward into the semi-circular screw groove 32. At this time, the screw 28 acts as a blocking force for the shaft sleeve 31. The user places the second transport cart 2 on the ground, and the four universal wheels 34 are in contact with the ground.

[0052] A rotating shaft 33 is rotatably mounted between each shaft sleeve 31 and the universal wheel 34; each fixed plate 35 is horizontally distributed with the rotating shaft 33, and each fixed plate 35 has a threaded hole 36 through its side end. The upper slide rail 22 is located in the middle of the second transport trolley 2, and a threaded sleeve 24 is threadedly fitted onto the surface of the threaded rod 26; a rotating shaft sleeve 25 is rotatably mounted below the threaded sleeve 24, and a side slide rod 27 is fixedly mounted at the end of the rotating shaft sleeve 25. The inner slider 23 slides inside the upper slide rail 22, and the movement of the threaded rod 26 will drive the side slide rod 27 to move. When the side slide rod 27 moves to the appropriate position, the user rotates the threaded sleeve 24. The threaded sleeve 24 is engaged with the threaded rod 26 through threads, so the rotation of the threaded sleeve 24 can adjust its own height. At the same time, the height adjustment of the threaded sleeve 24 will drive the height adjustment of the rotating shaft sleeve 25.

[0053] Working principle:

[0054] In the first step, when the user uses the first transport trolley 1 to move logistics goods, the user places large items on the first transport trolley 1 and small items on the second transport trolley 2. Since there are many logistics goods, the small items on the second transport trolley 2 can be stacked. When the user needs to retrieve the items stacked at the bottom, the user can move the threaded rod 26 to the side of the goods, and then rotate the side sliding rod 27 to position it between the goods to be retrieved and the goods above it. At this point, the side sliding rod 27 provides some support, making it easier for the user to pull out the bottom goods without causing the top goods to fall out. In case of goods falling, when the user needs two independent trolleys, the user can pull the second transport trolley 2 upwards, moving it away from the four side support rods 12. At the same time, the user can pull out the T-shaped handle 47 at the bottom of the second transport trolley 2 and rotate the four casters 34 downwards to contact the ground. At this time, the second transport trolley 2 becomes an independent trolley. By designing the first transport trolley 1 and the second transport trolley 2 to be detachable, they can serve as two layers of classification when not detached, and can serve as two independent trolleys when detached, greatly improving the convenience of loading and unloading goods. At the same time, the side sliding rod 27 set on the second transport trolley 2 can further improve the convenience of unloading.

[0055] In the second step, when the user places large goods on the first transport trolley 1, the user can first lift the side of the goods onto the first transport trolley 1. Since the surface of the top plate 17 is arc-shaped, when the goods come into contact with the top plate 17, it will press the top plate 17 downward. The top plate 17 moves downward, causing the support plate 16 to move downward inside the T-shaped slide 14. At the same time, the top plate 17 will cause the two springs 15 to compress and deform. When the goods have completely moved onto the first transport trolley 1 and the goods are separated from the top plate 17, the springs 15 will cause the top plate 17 to pop out through elastic force. At this time, after the top plate 17 is reset, it will block the goods on the first transport trolley 1 and prevent the goods from falling from the sides during movement. By setting a movable top plate 17 on the first transport trolley 1, the goods can slide into the first transport trolley 1 without affecting the goods, and at the same time, it can prevent the goods from falling off the first transport trolley 1, which greatly improves the protection of the goods during transportation.

[0056] When a large item is placed on the first transport trolley 1, and the height of the item is higher than the fixed collar 13, the top of the item will contact the bottom of the second transport trolley 2 as it moves into the first transport trolley 1. At the same time, the item will contact multiple sliding wheels 46, which provide good smoothing and facilitate the item's entry into the first transport trolley 1. The item can also raise the height of the second transport trolley 2. The second transport trolley 2 moves upward outside the four side support rods 12. Since the second transport trolley 2 is subject to its own gravity, it can exert a certain squeezing effect on the item below, preventing it from sliding during transport and further improving the stability of the transport.

[0057] Thirdly, when using the side slide bar 27 to assist in unloading goods, the user can first slide the threaded rod 26. The movement of the threaded rod 26 drives the inner slider 23 to move. The inner slider 23 slides inside the upper slide rail 22. At the same time, the movement of the threaded rod 26 will drive the side slide bar 27 to move. When the side slide bar 27 moves to the appropriate position, the user rotates the threaded sleeve 24. The threaded sleeve 24 is engaged with the threaded rod 26 through the thread, so the rotation of the threaded sleeve 24 can adjust its own height. At the same time, the height adjustment of the threaded sleeve 24 will drive the height adjustment of the rotating shaft sleeve 25, which will drive the height adjustment of the side slide bar 27. After the height adjustment of the side slide bar 27 is completed, the user inserts the side slide bar 27 between two goods. At this time, the user can then take out the bottom goods. By setting a side slide bar 27 on the second transport trolley 2, the side slide bar 27 can be used to assist in supporting the goods, making it easier for the user to pull out the bottom goods. At the same time, the height and position of the side slide bar 27 can be adjusted, so that goods in various positions on the second transport trolley 2 can be taken out, which greatly improves the convenience of unloading.

[0058] When the user takes the second transport cart 2 for independent use, the user first rotates the four screws 28 upwards, disengaging them from the threaded holes 36 in the four fixing plates 35. At this point, the user can rotate the caster wheel 34 downwards. This downward rotation of the caster wheel 34 drives the axle sleeve 31 to rotate via the pivot 33. After the axle sleeve 31 rotates 90 degrees, the caster wheel 34 and the axle sleeve 31 are in a vertical position. Then, the user rotates the screws 28 downwards, causing them to enter the semi-circular threaded groove 32. At this point, the screws 28 act as a guide for the axle sleeve 31. The second transport cart 2 serves as a barrier. When the user places the second transport cart 2 on the ground, the four casters 34 are in contact with the ground. By designing the casters 34 to be able to rotate at an angle, the casters 34 will not obstruct the goods on the first transport cart 1 when the second transport cart 2 is not used independently. At the same time, the multiple casters 34 are located on both sides of the second transport cart 2, which can play a certain protective role and prevent the side wall of the second transport cart 2 from colliding with other objects. When the second transport cart 2 is in use, it can also play a supporting and sliding role, which greatly improves the convenience of transporting goods with the second transport cart 2.

[0059] When the user pulls the second transport trolley 2, the user first pulls the T-shaped handle 47 outward. The force on the T-shaped handle 47 drives the second slide plate 45 and the first slide plate 42 to move. The second slide plate 45 and the first slide plate 42 slide inside the lower slide rail 4. When the lower locking plate 43 under the first slide plate 42 engages between the two side baffles 41, it stops. At this time, the second slide plate 45 and the T-shaped handle 47 are exposed outside the second transport trolley 2. The user can rotate the T-shaped handle 47 upward. The rotation of the T-shaped handle 47 drives the second slide plate 45 to rotate. The second slide plate 45 rotates at the end of the first slide plate 42 through the lower slide wheel 46. At this time, the second slide plate 45 and the T-shaped handle 47 combine to form the pull rod of the second transport trolley 2. By designing the second slide plate 45 and the T-shaped handle 47 to be retractable into the second transport trolley 2, they do not occupy space when not in use. Moreover, the lower slide wheel 46 under the second slide plate 45 and the first slide plate 42 can also play a smooth sliding role, which greatly improves the ease of use of the second transport trolley 2.

[0060] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
