Description

Technical Field

[0001] This utility model relates to the field of counterbalance forklift manufacturing, specifically to a lever-type traction pin for a counterbalance forklift. Background Technology

[0002] In the design and application of counterbalance forklifts, the tow pin, as a core component, directly affects the forklift's ease of operation, stability, and overall performance. However, existing tow pin designs have many limitations, making it difficult to meet the modern forklift industry's demands for high efficiency, low cost, and wide applicability.

[0003] Traditional counterbalance forklifts typically use a lead pin that is either welded directly to the pin shaft or has a handle attached. This design requires the operator to lift the entire lead pin during use, placing high demands on the structural design of the lead pin hole. If the lead pin hole is positioned too high, it results in an excessively long and heavy pin shaft, significantly increasing manufacturing costs. For heavy-duty counterbalance forklifts, this traditional lead pin design not only increases material usage and manufacturing complexity but also makes operation cumbersome and laborious.

[0004] Furthermore, the existing tow pin design has significant shortcomings in terms of space utilization. Due to the limitations of the tow pin hole position and structure, it is difficult to achieve higher space optimization in the design of counterbalance forklifts, thus affecting the overall layout and performance of the forklift. This limitation is particularly prominent under varying working conditions, restricting the forklift's applicability and operational flexibility.

[0005] To overcome the aforementioned shortcomings, the industry urgently needs a new type of counterbalanced tow pin design. This design should be widely applicable, adaptable to the needs of forklifts of different tonnages and structures; simultaneously, it should simplify the manufacturing process, reduce production costs, and improve ease and labor-saving operation. Furthermore, the new tow pin should also consider aesthetics and practicality to enhance the overall user experience. Utility Model Content

[0006] The purpose of this invention is to provide a lever-type towing pin for counterbalance forklifts. Utilizing the lever principle, the towing pin can be raised to a usable position simply by pulling up the handle at a certain angle. This makes operation simple and labor-saving, requires less operating space at the counterbalance towing pin hole, and allows for higher space utilization in counterbalance design. The length and specifications of the chain can be freely adjusted according to different tonnages and structures of counterbalances, making it widely applicable, low in manufacturing cost, and maximizing the user experience.

[0007] To achieve the above objectives, the present invention provides a lever-type traction pin for a counterbalance forklift, comprising a lever-type traction pin for installation at the traction pin hole of the counterbalance. The lever-type traction pin includes an upper cover plate, an iron chain located below the upper cover plate, and a pin located below the iron chain. Both the iron chain and the pin are vertically arranged. The upper and lower ends of the iron chain are respectively connected to the bottom surface of the upper cover plate and the upper end surface of the pin. The pin forms a lever structure with the upper cover plate through the iron chain, and the pin can be lifted using the lever principle.

[0008] Preferably, one end of the upper cover plate is bent upwards at an angle to form a bent section of the upper cover plate.

[0009] Preferably, the bend of the upper cover plate bending section is located at 4 / 5 of the length of the straight section on the bottom surface of the upper cover plate.

[0010] Preferably, the bending angle at the bend of the upper cover plate bending section is 135 degrees.

[0011] Preferably, the straight section of the bottom surface of the upper cover plate acts as a fulcrum to support the lever movement.

[0012] Preferably, the upper cover plate has a waist-shaped hole in the middle of the bent section to facilitate lifting.

[0013] Preferably, the two end corners at the top of the bent section of the upper cover plate are rounded.

[0014] Preferably, the bottom surface of the upper cover plate is provided with a round steel a for connecting the iron chain, and the top of the pin is provided with a round steel b for connecting the iron chain.

[0015] Preferably, along the width direction, the round steel a is located at 1 / 2 of the straight section of the bottom surface of the upper cover plate.

[0016] Preferably, the round steel a is welded to the bottom surface of the upper cover plate, and the round steel b is welded to the upper end surface of the pin.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention cleverly utilizes the lever principle, allowing operators to easily raise the tow pin to a usable position by applying only a small force to the handle and pulling it up at a certain angle. This design greatly simplifies the operation process, making it easier and less strenuous, and effectively reducing the operator's workload. The tow pin requires less operating space at the counterweight tow pin hole, providing greater flexibility in counterweight design and enabling higher space utilization. This is significant for optimizing the overall layout of the forklift and improving its stability and operational performance.

[0019] The length and specifications of the chain can be freely adjusted according to different tonnages and counterbalanced structures, making this tow pin widely applicable. Whether it's a small-tonnage or large-tonnage counterbalanced forklift, it can be adapted by adjusting the chain parameters to meet the needs of different working conditions. The design of this tow pin significantly reduces production costs by reducing material usage and simplifying the manufacturing process. This not only enhances the product's market competitiveness but also provides users with a more cost-effective option.

[0020] This utility model's lever-type towing pin for counterbalance forklifts improves operational convenience and reduces costs while also considering aesthetics and practicality, maximizing the user experience. Through these combined advantages, this utility model provides an innovative and practical solution for the development of counterbalance forklift towing pin technology. Attached Figure Description

[0028] In the design of counterbalance forklifts, the counterbalance unit 1 is a core component, and its structure directly affects the stability and ease of operation of the forklift. To improve the performance and applicability of the towing pin, this utility model discloses a lever-type towing pin structural design for counterbalance forklifts. This design, through ingenious construction and the application of the lever principle, achieves ease of operation, labor-saving operation, and cost reduction, while also considering aesthetics and practicality.

[0029] The lever-type traction pin 2 is installed at the traction pin hole of the counterweight 1. It mainly consists of an upper cover plate 21, round steel a22, iron chain 23, round steel b24, and pin 25. The upper cover plate 21, as the core structural component of the lever-type traction pin 2, has its bottom straight section (the straight section L of the bottom surface of the upper cover plate) acting as a fulcrum to support the lever movement of the entire lever-type traction pin 2. Along the width direction, at halfway point of the straight section L of the bottom surface of the upper cover plate, the round steel a22 is welded to the bottom surface of the upper cover plate 21. The round steel a22 and round steel b24 are connected by the iron chain 23, while the round steel b24 is welded to the upper end face of the pin 25. This invention utilizes the iron chain 23 and the straight section L of the bottom surface of the upper cover plate as a fulcrum to lift the pin 25 using the lever principle, reducing the material usage of the pin 25 and lowering costs.

[0030] The design of the top cover 21 not only meets functional requirements but also fully considers ease of operation and safety. Along its length, at 4 / 5 of the distance from the end of the straight section L on the bottom surface of the top cover 21, a 135-degree bend is made to form the handle portion (bent section A of the top cover). The two corners of the upper edge of the bent section A are rounded to avoid potential injury to the operator from sharp right angles. Furthermore, a waist-shaped hole is provided in the middle of the bent section A to facilitate lifting the lever-type traction pin 2, further enhancing ease of use.

[0031] The length and specifications of the chain 23 can be flexibly adjusted according to the counterweight 1 of different tonnages and structures, making the lever-type towing pin 2 widely applicable, low in manufacturing cost, and maximizing the user experience. By adjusting the length of the chain 23, it can be adapted to the structural requirements of various counterweight forklifts, ensuring that the lever-type towing pin 2 maintains good performance under different working conditions.

[0032] In practical implementation, the operation of the lever-type traction pin 2 is as follows: When it is necessary to lift the lever-type traction pin 2, the operator only needs to apply a certain force to the handle. Utilizing the lever principle, the pin 25 can be lifted to the usable position, making the operation simple and labor-saving. This design requires less operating space at the traction pin hole of the counterweight 1, allowing the counterweight 1 to achieve a higher space utilization rate in its design.

[0033] This utility model's lever-type towing pin for counterbalance forklifts achieves ease of operation and labor-saving performance through its unique structural design and the application of the lever principle. The bending design of the upper cover plate 21 not only improves space utilization but also enhances operational safety and comfort. The flexible adjustment capability of the chain 23 further expands the applicability of the lever-type towing pin 2, reduces manufacturing costs, and improves the user experience. This design not only meets the needs of large-tonnage forklifts but also provides new ideas for the future development of counterbalance towing pins. By adjusting the length of the chain 23, the lever-type towing pin 2 can adapt to the structure of various counterbalance forklifts, featuring simple manufacturing process, low cost, and aesthetic appeal. Simultaneously, the lever principle enables quick and convenient use of the towing pin.

[0034] This utility model can be adapted to various counterbalance forklift structures by adjusting the length of the iron chain 23. It has a wide range of applications, simple process, low cost, and is aesthetically pleasing and practical. Through the lever principle, the counterbalance forklift towing pin can be used quickly and conveniently.
