Description

Technical Field

[0001] This utility model relates to the field of fire truck pedal technology, specifically to a suspended pedal for fire trucks. Background Technology

[0002] Fire truck suspension steps are typically located below the fire truck doors to provide stable support for firefighters entering and exiting the vehicle. For example, patent document CN209581321U discloses a suspended telescopic fire truck step. This step involves pressing down on a movable plate, compressing a second spring, pulling a steel wire rope, and causing a winding wheel to rotate. The rotating wheel pulls a sliding block, compressing the spring and separating it from the extension rod. This, in turn, pushes a fixed plate downwards via the second spring. The fixed plate moves downwards, pulling the extension rod downwards, raising the first spring. When the step reaches a suitable height from the ground, the foot is moved onto the anti-slip strip. The second spring returns to its original state, pushing the movable plate upwards and stopping the tension on the steel wire rope. The spring on the sliding block returns to its original state, pushing the sliding block towards the extension rod to engage. The other foot is then placed on the support plate to enter the cab. This allows for quick entry into the cab, avoiding situations where the vehicle is too high and difficult to enter, while also preventing dangerous situations and improving safety. It is applicable to various vehicles.

[0003] However, the existing stepping board consists of multiple flat plates, and the misalignment space between adjacent steps is small. This results in firefighters not having sufficient foot space to support themselves when quickly getting on and off the vehicle, which can easily lead to accidental slippage and reduce the effectiveness of the stepping board.

[0017] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0018] This utility model discloses a fire truck suspended pedal.

[0019] This utility model provides, for example Figure 1-3 The fire truck suspended pedal shown includes a suspension bracket 1, a connecting frame 2 fixedly provided at the end of the suspension bracket 1, and multiple sets of spaced support rods 3 fixedly provided on the inner wall of the connecting frame 2. Each set of support rods 3 has 2 support rods, and the support rods 3 are L-shaped support rods. The walls of two adjacent support rods 3 are slidably fitted with a foot pedal 4, and the surface of the foot pedal 4 is fixedly provided with anti-slip stripes 5. Both sides of the pedal 4 are fixedly provided with swing rods 6, and the upper end of the inner wall of the connecting frame 2 is fixedly provided with a support shaft 7. The shaft wall of the support shaft 7 is provided with two symmetrically arranged swing plates 8. The interior of the two swing plates 8 is provided with strip holes 9, and multiple swing rods 6 are slidably arranged in the strip holes 9. The lower ends of the two swing plates 8 are jointly provided with a pushing mechanism for driving the swing plates 8 to rotate. The pushing mechanism includes an electric push rod 10. The lower sides of the two swing plates 8 are jointly fixed with a U-shaped frame 11. The lower end of the connecting frame 2 is fixed with a base plate 12. The top of the base plate 12 is fixed with a support block 13. The lower end of the electric push rod 10 is rotatably engaged with the support block 13 shaft pin. The output shaft of the electric push rod 10 is fixedly provided with a rotating ring 14, and the lower side of the U-shaped frame 11 is fixedly provided with a connecting plate 15. The connecting plate 15 has a through hole 16 that is fitted to the rotating ring 14.

[0020] In order to effectively limit the distance traveled by pressing the pedal, such as Figure 2-3 As shown, the side of the pedal 4 is provided with a sliding groove 18 for the support rod 3 to pass through. Both sides of the inner wall of the sliding groove 18 are provided with limiting grooves 19. The support rod 3 is fixed with two symmetrically arranged limiting blocks 20, which are slidably disposed in the limiting grooves 19.

[0021] Working principle: First, the entire pedal device needs to be fixedly installed at the preset position below the fire truck door by using the mounting bolt 17 at the lower end of the side of the suspension bracket 1 away from the connecting frame 2. This ensures that the suspension bracket 1 is firmly connected to the fire truck body, providing a stable foundation for the subsequent deployment and use of the pedal. When firefighters need to get on and off the fire truck, the pushing mechanism is activated to achieve the lateral deployment of the pedal 4. The lower end of the electric push rod 10 in the pushing mechanism is rotated and engaged with the shaft pin of the support block 13 at the top of the base plate 12. After the electric push rod 10 is activated, its output shaft will extend outward, driving the rotating ring 14 fixed at the end to move. The rotating ring 14 passes through the through hole 16 of the connecting plate 15 on the lower side of the U-shaped frame 11. Therefore, when the rotating ring 14 moves, it will push the connecting plate 15, thereby driving the U-shaped frame 11 and the two swing plates 8 fixedly connected to the U-shaped frame 11 to move synchronously. The swing plate 8 is rotatably mounted on the support shaft 7 at the upper end of the inner wall of the connecting frame 2. Under the push of the U-shaped frame 11, the two swing plates 8 will rotate synchronously around the axis of the support shaft 7. Since the swing rods 6 fixed on both sides of the pedal 4 are slidably mounted in the strip hole 9 inside the swing plate 8, when the swing plate 8 rotates, the inner wall of the strip hole 9 will generate a lateral thrust on the swing rod 6, pushing the swing rod 6 to drive the pedal 4 to slide along the rod wall of the two adjacent support rods 3 (the support rods 3 have an L-shaped structure, which provides stable sliding support for the pedal 4). The side of the foot pedal 4 is provided with a sliding groove 18 for the support rod 3 to pass through. The limiting grooves 19 on both sides of the inner wall of the sliding groove 18 are slidably engaged with the limiting blocks 20 fixed to the wall of the support rod 3. During the sliding of the foot pedal 4, the limiting blocks 20 move along the limiting grooves 19, which can effectively limit the sliding distance of the foot pedal 4 and prevent the foot pedal 4 from falling off due to excessive sliding and detaching from the support rod 3. As multiple foot pedals 4 are simultaneously extended laterally, the distance between adjacent foot pedals 4 increases, forming sufficient foot support space. When the foot pedal 4 is extended to the preset position, the electric push rod 10 stops working, and firefighters can step on the surface of the foot pedal 4 to get on and off the fire truck. The anti-slip stripes 5 fixed on the surface of the foot pedal 4 can increase the friction between the foot and the pedal, effectively preventing firefighters from slipping during rapid ascent and descent. When the pedals are not needed, the output shaft of the electric push rod 10 retracts, causing the rotating ring 14, connecting plate 15, and U-shaped frame 11 to move in the opposite direction. This causes the swing plate 8 to rotate in the opposite direction around the support shaft 7. The swing plate 8 pulls the pedal 4 back along the support rod 3 through the cooperation of the strip hole 9 and the swing rod 6 until the multiple pedals 4 retract to their initial state, reducing the space occupied by the pedals and avoiding affecting the movement of the fire truck.

[0022] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
