Problems solved by technology

The pedals and matching boards in this patent are designed for the entire surface and cannot be folded and stretched. When the car is not in use, the pedals are horizontally arranged at both ends of the car, which increases the overall width of the car, resulting in two adjacent Cars need to reserve a lot of space when parking, resulting in a waste of parking spaces
Moreover, after increasing the overall width of the car, the pedals are likely to cause scratches to adjacent parked cars, and the pedals are also easily damaged by adjacent parked cars.
There is also a type of pedal, which needs to be manually reduced in size. Not only does the user need to bend over to operate, but also only rely on the other hand to support the vehicle. When the vehicle is supported by one hand, the stability of the vehicle is poor. easy to dump

Embodiment 1

[0024] Embodiment 1: as figure 1 , 2 . As shown in 3, a telescopic pedal includes a pedal body 1 and a main shaft tube 2 fixedly connected with the crank connecting rod. It is rotatably connected with the pedal body. The side of the pedal body is equipped with a telescopic part 3, the two ends of the telescopic part 3 are fixed with a slide bar 4, the pedal body is provided with a slide hole that is slidably connected with the slide bar, the middle part of the telescopic part is fixed with a fixed rod 5, and on the main shaft tube There is a threaded hole 21 threadedly connected with the fixed rod, and the depth of the threaded hole is greater than the length of the fixed rod. Such as Figure 4 As shown, the slide rod is in the shape of a "T", and the slide rod includes a rod body 41 and a limit head 42. The slide hole includes a hole body 61 matching the diameter of the limit head and a limit hole 62 matching the diameter of the rod body. A return spring 8 is sleeved, and...

Embodiment 2

[0026] Embodiment 2: The structure of this embodiment is basically the same as that of Embodiment 1, the difference is that, as Figure 5 As shown, the outer surface of the main shaft tube is covered with a sleeve body 13, and the outer surface of the main shaft tube and the sleeve body are connected by bearings. There are two pedal bodies, and both sides of the sleeve body are provided with pedal bodies. The bodies are connected by a rotating shaft 9, the rotating shaft is arranged vertically to the axis of the main shaft tube, the pedal body is rotationally connected with the sleeve body through the rotating shaft, and the upper and lower edges of the sleeve body near one end of the telescopic portion are provided with arc surfaces. Fixing holes 11 are arranged on the upper and lower ends of the casing, and the diameter of the fixing holes 11 is greater than or equal to the outer diameter of the fixing rod. Such as Figure 6 As shown, a positioning hole 10 is coaxially arra...

Abstract

The invention relates to a pedal, in particular to a retractable pedal. The retractable pedal comprises a pedal body and a spindle pipe fixedly connected with a crank connecting rod, wherein the spindle pipe is rotationally connected with the pedal body, a retracting part is arranged on the side surface of the pedal body, slide rods are arranged at two ends of the retracting part, slide holes glidingly connected with the slide rods are formed in the pedal body, a fixed rod is arranged in the middle of the retracting part, and a threaded hole in threaded connection with the fixed rod is formed in the spindle pipe; the spindle pipe is rotationally connected with the pedal body and fixedly connected with the crank connecting rod; and the pedal body and the spindle pipe rotate relatively in a pedaling process. The retractable pedal has the benefits of retracting capacity, reduction of cross occupied space, convenience in retraction, non-requirement for manual adjustment and the like.

Description

technical field [0001] The invention relates to a pedal, in particular to a retractable pedal. Background technique [0002] Existing bicycle or spare foot pedals are integrally designed and fixed on the crank connecting rod through the main shaft. When the car does not need to be used, the pedals are horizontally arranged at both ends of the car, which increases the overall width of the car, causing two adjacent cars to reserve a large space when parking, resulting in a waste of parking spaces. And after increasing the overall width of the car, the pedals are likely to cause scratches to the adjacent parked cars, and the pedals are also easily damaged by the adjacent parked cars. There is also a type of pedal, which needs to be manually reduced in size. Not only does the user need to bend over to operate, but also only rely on the other hand to support the vehicle. When the vehicle is supported by one hand, the stability of the vehicle is poor. Easy to pour. [0003] For...
