[0002] When transporting goods, especially those that are large in size or weight, trolleys are needed for transfer. When transporting some large or long goods, trolleys often cannot fit into narrow spaces (such as elevators, corridors, or doorways) because the goods are too tall, making the transfer difficult. Summary of the Invention
[0003] This invention provides a trolley with an adjustable carrying angle to solve the problem of existing trolleys being unable to accommodate goods that are too tall, thus making goods transfer difficult.
[0004] To solve the above-mentioned technical problems, this utility model provides a trolley with an adjustable carrying angle, including a trolley body, a shelf, a locking mechanism, a telescopic mechanism, and a translation mechanism;
[0005] Both the translation mechanism and the telescopic mechanism are mounted on the vehicle body. The upper side of the shelf is rotatably connected to the telescopic mechanism, and the lower side of the shelf is connected to the translation mechanism. The telescopic mechanism can extend and retract in the vertical direction.
[0006] The locking mechanism has a specific locked state and an unlocked state. In the locked state, the locking mechanism locks the shelf to the vehicle body to temporarily maintain the relative fixation between the shelf and the vehicle body. In the unlocked state, the shelf slides relative to the vehicle body along a first direction via the translation mechanism.
[0007] Optionally, the telescopic mechanism includes a crossbar and two telescopic rods, the two telescopic rods being spaced apart on the vehicle body, one end of the crossbar being connected to the upper end of one of the telescopic rods, and the other end of the crossbar being connected to the upper end of the other telescopic rod;
[0008] The shelf and the crossbar are rotatably connected so that the shelf can rotate around the crossbar.
[0009] Optionally, the telescopic rod includes a plug rod, a first cylinder, and a second cylinder. The first cylinder is fixed to the vehicle body, and the second cylinder is inserted into the first cylinder. The first cylinder is provided with a first through hole that extends radially through it, and the second cylinder is provided with a plurality of second through holes that extend radially through it. The plurality of second through holes are spaced apart along the axial direction of the second cylinder, and the plug rod can be inserted into the coaxial first through hole and second through hole.
[0010] The two ends of the crossbar are respectively connected to the second cylinders of the two telescopic rods.
[0011] Optionally, the translation mechanism includes a first slide rail assembly and a second slide rail assembly. The first slide rail assembly includes a first slide rail and a first slider. The first slide rail and the first slider are slidably engaged. The first slide rail is fixed to the vehicle body, and the shelf is fixed to the first slider.
[0012] The second slide rail assembly includes a second slide rail and a second slider, which slide in cooperation with each other. The second slide rail is fixed to the vehicle body, and the shelf is fixed to the second slider. The first slide rail and the second slide rail are spaced apart.
[0013] Optionally, the shelf includes a mounting plate, a rotating cylinder, and a bracket. The two ends of the mounting plate are respectively fixed to the first slider and the second slider, the lower end of the bracket is fixed to the mounting plate, and the rotating cylinder is disposed at the upper end of the bracket.
[0014] The crossbar is a round bar, and the rotating cylinder is sleeved on the crossbar.
[0015] Optionally, the bracket is provided with a groove for accommodating an object.
[0016] Optionally, the locking mechanism includes a limiting plate, a limiting rod, and a limiting rope. The limiting plate is fixed to the vehicle body and has a through hole. One end of the limiting rope is fixed to the mounting plate, and the other end of the limiting rope passes through the through hole. The limiting rope is tied to the limiting rod, and the limiting rod is located on the side of the limiting plate away from the mounting plate.
[0017] In the locked state, the limiting rod abuts against the limiting plate, and the length of the limiting rope between the limiting rod and the mounting plate is equal to the shortest distance between the limiting rod and the mounting plate, so that the limiting rope between the limiting rod and the mounting plate is taut.
[0018] In the unlocked state, the length of the limiting rope between the limiting rod and the mounting plate is greater than the shortest distance between the limiting rod and the mounting plate, and the limiting rope between the limiting rod and the mounting plate is slack.
[0019] Optionally, the vehicle body includes a platform, a handle, and multiple wheels. The multiple wheels are fixed below the platform, the handle is fixed to the platform, the telescopic rod is fixed to the platform, and the first slide rail and the second slide rail are disposed on the platform.
[0020] Optionally, the shelf is provided with a binding rope, one end of which is fixed to the shelf, and the other end of which is wrapped around the object and tied to the shelf or the binding rope.
[0021] Optionally, the translation mechanism is one of a double-speed chain, a belt conveyor, and a chain conveyor.
[0022] This utility model provides a trolley with an adjustable carrying angle. The height of the upper part of the shelf is adjusted via a telescopic rod, thereby adjusting the tilt of the goods on the shelf and lowering the overall height of the goods. Simultaneously, due to the weight of the goods, as the upper part of the shelf rises or falls, the lower part of the shelf moves freely along a second direction on the translation mechanism under its guidance, thus adjusting the center of gravity of the goods to a suitable position. Therefore, the translation mechanism, capable of continuous displacement and guidance, ensures that the trolley can freely adjust its tilt even when carrying goods. Furthermore, during tilt adjustment, the weight of the goods affects the translation distance of the lower part of the shelf on the translation mechanism, ensuring the stability of the center of gravity.

[0029] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0030] In the description of this utility model, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and 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 should not be construed as a limitation of this utility model. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] Reference Figure 1 and Figure 2This utility model discloses a trolley with an adjustable carrying angle, comprising a trolley body 1, a shelf 3, a locking mechanism, a telescopic mechanism, and a translating mechanism 2. The translating mechanism 2 and the telescopic mechanism are both mounted on the trolley body 1. The upper side of the shelf 3 is rotatably connected to the telescopic mechanism, and the lower side of the shelf 3 is connected to the translating mechanism 2. The telescopic mechanism is capable of extending and retracting in the vertical direction. The locking mechanism has a locked state and an unlocked state. In the locked state, the locking mechanism locks the shelf 3 onto the trolley body 1 to temporarily maintain the relative fixation of the shelf 3 and the trolley body 1. In the unlocked state, the shelf 3 slides relative to the trolley body 1 in a first direction via the translating mechanism 2.
[0033] In this embodiment, an object is placed on the shelf 3. The person adjusts the length of the telescopic rod 5 up or down, thereby causing the shelf 3 to rotate around the upper end of the telescopic rod 5. This causes the lower end of the shelf 3 to move on the translation mechanism 2, thereby changing the center of gravity of the shelf 3. This allows the height of the object and the vehicle body 1 to be adjusted, making it easier for the vehicle body 1 and the object on it to enter the elevator or pass through low doors.
[0034] The height of the upper part of the shelf 3 is adjusted by the telescopic rod 5, thereby adjusting the tilt of the goods on the shelf 3 and reducing the overall height of the goods. Simultaneously, due to the weight of the goods, after the upper part of the shelf 3 is raised or lowered, the lower part of the shelf 3 will freely move along the second direction on the translation mechanism 2 under the guidance of the translation mechanism 2, thus adjusting the center of gravity of the goods to a suitable position. Therefore, the translation mechanism 2, which can continuously move and guide, ensures that the tilt of the trolley can be freely adjusted even when carrying goods. Furthermore, during the tilt adjustment process, the weight of the goods affects the translation distance of the lower part of the shelf 3 on the translation mechanism 2, also ensuring the stability of the center of gravity.
[0035] Reference Figure 1 As an example, the telescopic mechanism includes a crossbar 54 and two telescopic rods 5, which are spaced apart on the vehicle body 1. One end of the crossbar 54 is connected to the upper end of one of the telescopic rods 5, and the other end of the crossbar 54 is connected to the upper end of the other telescopic rod 5. The shelf 3 is rotatably connected to the crossbar 54 so that the shelf 3 rotates around the crossbar 54.
[0036] Reference Figure 2More specifically, the telescopic rod 5 includes a plug rod 53, a first cylinder 51, and a second cylinder 52. The first cylinder 51 is fixed to the vehicle body 1 and extends upward. The second cylinder 52 is inserted into the first cylinder 51. The first cylinder 51 is provided with a first through hole 511 that extends radially through it. The second cylinder 52 is provided with a plurality of second through holes 521 that extend radially through it. The plurality of second through holes 521 are spaced apart along the axial direction of the second cylinder 52. When the first through hole 511 and one of the second through holes 521 are coaxial, the plug rod 53 is inserted into the first through hole 511 and the second through hole 521. The two ends of the crossbar 54 are respectively connected to the second cylinders 52 of the two telescopic rods 5.
[0037] In this embodiment, when adjusting the height, the plug rod 53 is first removed from the first through hole 511 and the second through hole 521. Then, the second cylinder 52 is lifted upward. After the second cylinder 52 reaches the appropriate height, the plug rod 53 is inserted into the first through hole 511 and the second through hole 521 after the second through hole 521 on the second cylinder 52 and the first through hole 511 on the first cylinder 51 are aligned.
[0038] In this embodiment, if the object is not heavy, it can be operated by one person. The plug rod 53 is taken out with one hand, and the crossbar 54 is lifted upward with the other hand, so that the second cylinder 52 rises. At this time, the end of the plug rod 53 can be inserted into the first through hole 511. The end of the plug rod 53 abuts against the outer wall of the second cylinder 52. After the crossbar 54 is raised to a suitable height and the first through hole 511 and the second through hole 521 are aligned, the plug rod 53 is pushed with one hand, and the plug rod 53 directly enters the second through hole 521.
[0039] If the object is heavy, multiple people are needed to operate it. One person is responsible for inserting the rod 53, while others are responsible for lifting the horizontal bar 54. After the horizontal bar 54 is at a suitable height and the first through hole 511 and the second through hole 521 are aligned, the rod 53 is inserted into the rod 53.
[0040] Reference Figure 2 As an example, the translation mechanism 2 includes a first slide rail 21 assembly and a second slide rail 21 assembly. The first slide rail 21 assembly includes a first slide rail 21 and a first slider 22, which are slidably engaged. The first slide rail 21 is fixed to the vehicle body 1, and the shelf 3 is fixed to the first slider 22. The second slide rail 21 assembly includes a second slide rail 21 and a second slider 22, which are slidably engaged. The second slide rail 21 is fixed to the vehicle body 1, and the shelf 3 is fixed to the second slider 22. The first slide rail 21 and the second slide rail 21 are spaced apart.
[0041] In this embodiment, the displacement mechanism uses slide rail 21 and slider 22 for movement. Slide rail 21 and slider 22 are common mechanical displacement components that are easy to obtain and inexpensive.
[0042] As an example, the shelf 3 includes a mounting plate 34, a rotating cylinder 35, and a bracket. The two ends of the mounting plate 34 are respectively fixed to the first slider 22 and the second slider 22. The lower end of the bracket is fixed to the mounting plate 34. The rotating cylinder 35 is disposed at the upper end of the bracket. The crossbar 54 is a round rod, and the rotating cylinder 35 is sleeved on the crossbar 54.
[0043] In other embodiments, the crossbar 54 may be square, and the bracket is rotatably connected to the crossbar 54 via a hinge.
[0044] As an example, the bracket is provided with a groove for accommodating objects. In this embodiment, the bracket includes a shelf 31, a bent plate 32, and a baffle 33. The upper end of the shelf 31 is connected to the rotating cylinder 35, and the lower end of the shelf 31 is connected to the bent plate 32. The end of the bent plate 32 away from the shelf 31 is connected to the baffle 33, so that the shelf 31, the bent plate 32, and the baffle 33 together form a groove for accommodating objects. The upper side of the mounting plate 34 is connected to the bent plate 32, and the lower side of the mounting plate 34 is connected to the slider 22.
[0045] As an example, the vehicle body 1 includes a platform 12, a handle 11, and a plurality of wheels 13. The plurality of wheels 13 are fixed below the platform 12, the handle 11 is fixed to the platform 12, the telescopic rod 5 is fixed to the platform 12, and the first slide rail 21 and the second slide rail 21 are disposed on the platform 12. In this embodiment, the platform 12 is preferably made of metal to improve its strength and load-bearing capacity.
[0046] As an example, the locking mechanism includes a limiting plate 41, a limiting rod 43, and a limiting rope 42. The limiting plate 41 is fixed to the vehicle body 1 and has a through hole 411. One end of the limiting rope 42 is fixed to the mounting plate 34, and the other end of the limiting rope 42 passes through the through hole 411. The limiting rope 42 is tied to the limiting rod 43.
[0047] In this embodiment, the limiting plate 41 is fixed to the handle 11 of the vehicle body 1. A through hole 411 is provided on the limiting plate 41. The inner diameter of the through hole 411 is generally larger than the diameter of the limiting rope 42. When the weight of the object is large, while one person is lifting the crossbar 54, another person can also pull the limiting rope 42 to move the object upward, thereby assisting in lifting the crossbar 54. Due to the existence of the limiting rope 42, the lifting of the crossbar 54 by one person is changed to two people lifting the crossbar 54 at the same time, which is more labor-saving. After lifting to a suitable height, the section of the limiting rope 42 away from the shelf 3 is tied to the limiting rod 43. The length of the limiting rod 43 is much larger than the diameter of the through hole 411. That is, the limiting rod 43 is on the side of the limiting plate 41 away from the translation mechanism 2. The limiting rod 43 is used to prevent the limiting rope 42 from moving towards the translation mechanism 2, thereby limiting the translation mechanism 2 from moving the highest point of the shelf 3 downward.
[0048] In this embodiment, the limiting rod 43 is independent of the limiting plate 41 and is not connected to the limiting plate 41. In other embodiments, the limiting rod 43 may be fixed to the limiting plate 41.
[0049] The use of the limiting rope 42 has the advantages of simple structure and low cost.
[0050] As an example, the shelf 3 is provided with a binding rope 6. One end of the binding rope 6 is fixed to the shelf 3, and the other end of the binding rope 6 is wrapped around an object and tied to the shelf 3 or the binding rope 6. In this embodiment, at least one binding rope 6 is provided. If multiple binding ropes 6 are provided, the binding ropes 6 are spaced apart from the lower end to the upper end of the shelf 3 to bind longer objects on the shelf 3.
[0051] Reference Figure 3 As an example, the translation mechanism 2 is one of the double-speed chain 23, belt conveyor 24 and chain conveyor, the translation mechanism 2 is disposed on the vehicle body 1, and the shelf 3 is disposed on the translation mechanism 2.
[0052] Reference Figure 3 When the translation mechanism 2 is a double-speed chain 23, the lower end of the shelf 3 is placed directly on the conveyor wheel on the double-speed chain 23.
[0053] Reference Figure 4 When the translation mechanism 2 is a belt conveyor 24 or a chain conveyor, the lower end of the shelf 3 is fixed on the belt of the belt conveyor 24 or the chain of the chain conveyor.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
