DETAILED DESCRIPTION

[0032] In order to enable those skilled in the art to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work should fall within the scope of protection of the present application.

[0033] like Figure 1 As shown, the present application provides a trolley, comprising:

[0034] The first bracket 1 has an operating handrail 2 fixedly installed at one end of the first bracket 1, which is convenient for the operator to hold steadily during operation to control the direction and speed of the trolley. At the other end of the first bracket 1, away from the operating handrail 2 and facing the ground, a hook 3 is fixedly installed. The hook 3 is made of high-strength material and can bear a large weight to ensure the safety of materials during the lifting process.

[0035] A support portion 4 movably connected to the first bracket 1, wherein one end of the support portion 4 is away from the first bracket 1 and is rotatably connected to a wheel assembly 5;

[0036] The trolley is also equipped with a first counterweight ring 6 fixedly connected to the first bracket 1. The first counterweight ring 6 is located at an end of the first bracket 1 away from the operating handrail 2 and opposite to the hook 3.

[0037] The trolley further includes: a second counterweight ring 7, which is opposite to the operating handrail 2 and fixedly mounted on one end of the first bracket 1; in a specific implementation, the second counterweight ring 7 is fixedly mounted at a position where the operating handrail 2 and the first bracket 1 are fixed, with an angle greater than 90 degrees and facing the ground;

[0038] The third counterweight ring 8 and the fourth counterweight ring 9 are respectively fixedly mounted at the two ends of the hollow steel pipe 10. In a specific implementation, the third counterweight ring 8 and the fourth counterweight ring 9 can be arranged at the two ends of the hollow steel pipe 10 facing the ground, or can be arranged at the two ends of the hollow steel pipe 10 relative to the second bracket 11.

[0039] A first counterweight ring 6, a second counterweight ring 7, a third counterweight ring 8 and a fourth counterweight ring 9 are arranged on the lifting trolley. When there are a lot of goods, the cargo bolt can be hung on the first counterweight ring 6 to increase the transportation capacity of the lifting trolley; when there are a lot of goods and the weight is light, the goods can be hung on the third counterweight ring 8 and the fourth counterweight ring 9 to increase the transportation capacity of the lever lifting trolley. When the goods are heavy, the first bracket 1 can be partially pulled out toward the operating handrail 2 by using the lever principle to increase the distance between the operating handrail 2 and the support part 4, and the counterweight cargo can be hung at the first counterweight ring 6, thereby greatly improving the transportation efficiency.

[0040] In many practical application scenarios, the structure of the operating armrest 2 is diverse and flexible, aiming to meet the operating requirements and usage environments of different devices. In a typical embodiment, Figure 4 As shown, the operating armrest 2 includes two key components: a seventh bracket 19 and an eighth bracket 20 .

[0041] The seventh bracket 19 is one of the main supporting structures of the operating handrail, and one end of the seventh bracket 1 is fixedly connected to the first bracket 1. This connection method can be welding, bolt connection or other reliable connection methods to ensure the stability and durability of the structure. The material of the seventh bracket 19 is usually selected as high-strength steel to withstand various forces and vibrations during operation.

[0042] At the end of the seventh bracket 19 away from the first bracket 1, a hole corresponding to the thickness of the eighth bracket 20 is opened. The hole is designed very accurately to ensure that the eighth bracket 20 can pass through smoothly and to ensure a close fit between the two to transmit force and maintain the stability of the structure.

[0043] The eighth bracket 20 is another important component of the operating armrest 2. It passes through the hole on the seventh bracket 19 and is fixedly connected to the seventh bracket 19 by welding. Welding is a common metal connection method that can provide high connection strength and sealing, ensuring that the connection between the eighth bracket 20 and the seventh bracket 19 is firm and reliable.

[0044] The material of the eighth bracket 20 is the same as that of the seventh bracket 19, which is also high-strength steel to ensure the strength and stability of the entire operating armrest 2. At the same time, the shape and size of the eighth bracket 20 are customized according to actual needs to meet the requirements of different devices for the operating armrest 2.

[0045] In addition, the design of the operating armrest 2 also has certain flexibility and scalability. For example, according to actual needs, more brackets or connectors can be added between the seventh bracket 19 and the eighth bracket 20 to expand the size and function of the operating armrest. At the same time, the shape and size of the bracket can also be changed to adapt to the operating requirements of different devices. This flexibility and scalability make the design of the operating armrest 2 more diversified and personalized, and can meet the actual needs of different users.

[0046] In some embodiments, Figure 2 As shown, the support portion 4 includes:

[0047] A hollow steel tube 10, wherein the diameter of the cavity of the hollow steel tube 10 is 1-3 mm larger than the diameter of the first bracket 1, so that the first bracket 1 can slide smoothly in the cavity of the hollow steel tube 10;

[0048] The second bracket 11 is fixedly installed at the center position of the side of the hollow steel pipe 10. The solid structure of the second bracket 11 can effectively disperse and withstand pressure and loads from all directions, thereby ensuring the stability of the entire support part 4.

[0049] The third bracket 12 and the fourth bracket 13, one end of the third bracket 12 is fixedly connected to the end of the second bracket 11 away from the hollow steel pipe 10, and the other end of the third bracket 12 is fixedly connected to one end of the hollow steel pipe 10; one end of the fourth bracket 13 is opposite to the third bracket 12, and is fixedly installed on the end of the second bracket 11 away from the hollow steel pipe 10, and the other end of the fourth bracket 13 is fixedly connected to the other end of the hollow steel pipe 10, so that the support part 4 can disperse the pressure more evenly when subjected to external force, effectively preventing structural deformation and damage;

[0050] The wheel assembly 5 includes a first wheel 14 , a second wheel 15 and an axle 16 . The axle 16 is rotatably disposed and fixed at the center of the first wheel 14 and the second wheel 15 .

[0051] In specific implementation, the first wheel 14 and the second wheel 15 are usually made of strong metal materials, such as steel or aluminum alloy, to ensure sufficient strength and durability. A through hole is designed at the center of the first wheel 14 and the second wheel 15 so that the axle 16 can pass through and be fixed therein by a bearing. This design allows the wheels to rotate freely around the axle 16, thereby realizing the driving function of the vehicle.

[0052] The axle 16 is a cylindrical component that is rotatably fixed to the center of the first wheel 14 and the second wheel 15 to connect the two wheels together. Both ends of the axle 16 are usually connected to bearings and other components to reduce friction and wear and make the wheels rotate more smoothly.

[0053] The second bracket 11 is fixedly mounted on the wheel assembly 5 at one end away from the hollow steel pipe 10, and is tightly connected to the wheel assembly 5 by bolts or other fasteners. This connection method not only ensures the stability of the wheel assembly 5, but also facilitates the maintenance and replacement of the wheel assembly 5.

[0055] A fifth bracket 17, one end of which is fixedly connected to the connection between the hollow steel pipe 10 and the second bracket 11, and the other end of which is fixedly mounted on one end of the axle 16 close to the first wheel 14;

[0056] A sixth bracket 18, one end of the sixth bracket 18 is fixedly connected to the connection between the hollow steel pipe 10 and the second bracket 11 relative to the fifth bracket 17, and the other end of the sixth bracket 18 is fixedly mounted on one end of the axle 16 close to the second wheel 15;

[0057] The fifth bracket 17 and the sixth bracket 18 provide necessary support during driving to prevent the vehicle body from unnecessary shaking.

[0058] In some embodiments, corresponding through holes are provided on the side walls of the first bracket 1 and the side walls of the hollow steel pipe 10, and the first bracket 1 passes through the cavity of the hollow steel pipe 10 to achieve movement of the position of the first bracket 1 in the hollow steel pipe 10. The first bracket 1 and the hollow steel pipe 10 are fixedly connected by a pin shaft. Preferably, the pin shaft passes through the through holes on the first bracket 1 and the side walls of the hollow steel pipe 10 to achieve fixation of the relative positions of the two.

[0059] The first bracket 1 of the present application passes through the middle of the hollow steel pipe 10 and can be adjusted in distance. The four counterweight rings can increase the amount of goods transported by the lever trolley. The third bracket 12, the fourth bracket 13, the fifth bracket 17, and the sixth bracket 18 can increase the safety and stability of the lever trolley.
