Description

Technical Field

[0001] The utility model relates to the technical field of trolleys, in particular to a pedal-operated braking trolley. Background Art

[0002] In modern logistics, medical and other fields, trolleys, as a common transportation tool, are widely used in work scenarios such as the handling, transfer and distribution of items. With the continuous increase in usage requirements, the design of trolleys is also constantly improved to meet the needs of different environments and tasks. However, during the use process, the safety and controllability of trolleys have always been one of the key issues that designers focus on.

[0003] Traditional trolleys usually rely on manual operation to achieve braking. Users need to manually pull or press certain components to slow down or stop the trolley. Although this design is simple, it has certain limitations in actual use. Especially when transporting heavy objects or using on uneven ground, manual braking not only requires a large amount of force, but also is prone to getting out of control due to inconvenient operation, increasing the workload and safety risks of users.

[0004] In addition, with the wide application of trolleys in the medical environment, especially in environments such as wards and operating rooms that require high safety and precise control, the traditional manual braking method seems inadequate. For example, when pushing medical devices or patients, operators need to ensure smooth movement while quickly and accurately controlling the speed and position of the trolley, and the traditional manual braking method is difficult to meet this requirement.

[0005] Therefore, it is very necessary to invent a pedal-operated braking trolley. Content of the Utility Model

[0006] In order to solve the above technical problems, the utility model provides a pedal-operated braking trolley to solve the problems that the existing braking structure of the trolley still requires manual braking, which requires a large amount of force and has a poor braking effect.

The top of the conduction guide post is fixedly installed with a foot pedal.

[0011] The brake shoe inside the rear wheel is a long strip-shaped steel metal plate, and a rubber sleeve with anti-slip patterns is wrapped on the outside of the brake shoe. The brake shoe can be bent by the downward movement of the conduction guide post and finally contact the tire of the rear wheel body; the guide tube is a metal tube that enables the conduction guide post to slide inside it, and the return spring can push the conduction guide post upward after the external force is removed. It has the following functions: ① Support and movement: The rear wheel is one of the key support points of the handcart, and together with the front universal wheel, it supports the weight of the entire cart, ensuring that the handcart can move smoothly; ② Braking function: The rear wheel is closely related to the braking system.

Through the transmission of this force, the effective operation of the braking brake pads is realized. The design of the pedal enables the applied force to be evenly distributed, ensuring the stability and reliability of the braking force; ③ Returning to the original position: When the user releases the pedal, the return spring will push the conduction guide columns upward, and the pedal will also return to its original position, making the braking brake pads leave the tires and releasing the brake. This function ensures that the trolley can move smoothly in the non-braking state; ④ Safety and convenience: The position and design of the pedal enable the user to conveniently operate at the rear of the trolley, ensuring the quickness and safety of the braking action, avoiding the complexity of manual braking operation, and improving the usability of the trolley.

[0022] As shown in the attached Figure 1 to the attached Figure 3 figure.

[0023] A pedal-operated braking handcart provided by the utility model comprises a cart body 1, a universal front wheel 3, a rear wheel 4 and a push handle 5, wherein: the universal front wheel 3 is fixedly installed at the front end of the cart body 1, the rear wheel 4 is installed behind the cart body 1, and the push handle 5 is installed behind the cart body 1.

[0025] A foot pedal 6 is fixedly installed above the rear wheel 4.

[0026] The rear wheel 4 comprises a rear wheel main body 41, a mounting block 43 and a braking brake pad 44, and the rear wheel main body 41 is fixedly installed below the reinforcing frame 2, and the mounting block 43 is fixedly installed below the reinforcing frame 2; the braking brake pad 44 is fixedly installed below the mounting block 43.

[0027] An extension bracket 42 is fixedly installed behind the rear wheel main body 41, and a guide tube 45 is fixedly installed above the extension bracket 42 behind the rear wheel main body 41, and a conduction guide post 46 is slidably installed inside the guide tube 45; the rear end of the braking brake pad 44 is rotatably connected to the conduction guide post 46 through a shaft, and a return spring 47 is connected between the guide tube 45 and the conduction guide post 46, and the top of the conduction guide post 46 is fixedly installed with the foot pedal 6.

[0028] The braking brake pad 44 inside the rear wheel 4 is a long strip-shaped steel metal plate, and a rubber sleeve with anti-slip patterns is wrapped outside the braking brake pad 44, and the braking brake pad 44 can be bent by the downward movement of the conduction guide post 46 and finally contact the tire of the rear wheel main body 41; the guide tube 45 is a metal tube that can enable the conduction guide post 46 to slide inside it, and the return spring 47 can push the conduction guide post 46 upward to return after the external force on the conduction guide post 46 is removed.

[0029] The foot pedal 6 is a steel metal plate, and both ends of the foot pedal 6 are respectively connected to two groups of conduction guide posts 46, and the middle position of the foot pedal 6 is bent downward; a steel metal plate with a certain width is arranged at the bent position in the middle of the foot pedal 6, and the distance between the bent position in the middle of the foot pedal 6 and the ground is 20 to 30 centimeters.

[0030] The pedal-operated braking handcart is a device that controls the braking system by stepping on the foot pedal to control the moving state of the handcart. Its working principle mainly includes the following steps:

[0031] 1. Initial state:

[0032] When the trolley is in its initial state, the rear wheels 4 are in a free rotation state, and the trolley can move freely. At this time, the pedal 6 is in the raised position, the conduction guide post 46 is at the highest point within the guide tube 45, there is no contact between the brake friction pads 44 and the tire of the rear wheel main body 41, and the return spring 47 maintains its normal elasticity.

[0033] 2. Apply braking force:

[0034] When it is necessary to decelerate or stop the trolley, the user steps on the pedal 6 with their foot. As the pedal 6 moves downward, the conduction guide posts 46 connected to both ends thereof also slide downward accordingly.

[0035] During the process of the conduction guide post 46 moving downward, under the guidance of the guide tube 45, it drives the brake friction pads 44 to move downward and gradually approach the tire surface of the rear wheel main body 41.

[0036] 3. Achieve braking:

[0037] When the brake friction pads 44 come into contact with the tire surface of the rear wheel main body 41, friction force begins to act on the tire, generating a braking force, which slows down the moving speed of the trolley until it completely stops. At this time, the brake friction pads 44 are bent due to the downward pressure of the conduction guide post 46 and closely adhere to the tire surface, thereby effectively braking the trolley.

[0038] 4. Release braking:

[0039] When the user releases the pedal 6, the pedal 6 loses the external force, and the return spring 47 starts to function, pushing the conduction guide post 46 upward back to its original position.

[0040] As the conduction guide post 46 rises, the brake friction pads 44 gradually leave the tire surface of the rear wheel main body 41, and the braking state of the trolley is released, restoring free movement.

[0041] 5. Restore the initial state:

[0042] The pedal 6 returns to its initial position under the action of the return spring 47, and the brake friction pads 44 are completely separated from the tire. At this time, the trolley can continue to move freely without obstacles, ready for the next operation.

[0043] Conclusion

[0044] The foot-operated braking trolley controls the working process of the braking system through the pedal 6, enabling the user to easily and effectively control the movement and stop of the trolley. The design of this system combines functions such as force conduction, friction braking, and automatic reset, ensuring the safety and operational convenience of the trolley during use. Through this mechanism, the trolley is not only suitable for daily handling tasks but also can provide a reliable braking function when needed, improving the safety of operation.
