[0032] The first embodiment, such as figure 1 An adapter sleeve 10 is provided between the pedal 1 and the crank 2. The adapter sleeve 10 is a cylinder with a through hole on the inside, a boss is provided at the front section, and a thread is provided at the rear section. The thread and the crank threaded hole of the crank 2 21 to match. After the adapter sleeve is installed on the crank, its front end protrudes from the crank hole for a certain distance. The adapter sleeve 10 plus the adjusting gasket 11 is screwed into the crank hole, and the bracket plate 4 plus double-sided adhesive 3 is installed into the thread of the adapter sleeve from the inner side of the crank (the slot is downward) and is pressed and fitted on the crank by the compression nut 5 Inside, the compression nut 5 is screwed and fixed with the threaded part of the rear section of the adapter sleeve 10 passing through the crank hole 21 . Install the guillotine assembly 6 on the rear side of the bracket ...

[0042] The third embodiment, such as Figure 9-10 , most of which are the same as in Embodiment 1, the difference is that the groove at the front end of the pedal shaft 12 is clamped from both sides by a torsion spring 504. on the inner end of the crank. A cover plate 501 may be provided outside the support plate and fixed by screws 502 . In this device, the torsion spring 504 has a certain elastic force. When there is no external force, the torsion spring 504 spontaneously closes to the middle, and under the external force when the pedal shaft is pushed into the crank, the torsion spring 504 is slightly separated and clamps the front end of the pedal shaft 12. Grooves for fixation.

[0043] Fourth embodiment, such as Figure 11 , the magnet adsorption type device, most of them are the same as the first embodiment, the difference is that the fixing method of the pedal shaft is different, in this program, the pedal shaft 12 does not need to be provided with a groove, and the...

[0045] Fifth embodiment, such as Figure 12 , the front end of the pedal shaft 12 is provided with a groove, the lower end of the crank 2 is provided with a through hole 301, the through hole penetrates into the crank hole, a spring 302 is arranged in the through hole 301, a ball 303 is arranged at the front end of the spring, and the front end of the through hole 301 The diameter of the hole is smaller than that of the ball 303, so that the ball 303 is lifted upwards under the action of the spring force, and part of the ball 303 protrudes from the through hole 301, but cannot run out of the through hole. A screw 304 is provided at the lower end of the through hole 301 to limit the position of the spring. In this way, when the pedal shaft 12 is inserted into the crank hole by force, the ball 303 will withstand the groove of the pedal shaft 12 under the action of the spring force, and limit the left and right movement of the pedal shaft. And when the pedal shaft is to be disas...

Abstract

The invention discloses a quick release pedal device without a tool, which comprises a pedal and a crank. A fixing device for fixing a solid crank shaft is arranged outside the crank, and the fixing device is not extended to the outside of the crank and also does not comprise an outside part of the crank. The fixing device of the quick release pedal device completely avoids the outside of the crank, so that legs or trouser legs of a rider are not touched by the pedal device, and looseness is avoided because of accidental touch. The quick release pedal device can be operated without the tool within 2 to 3 seconds, has briefness, quickness and reliable performance, and also can shorten a traverse width of a bicycle.

Description

technical field [0001] The invention relates to a quick-release pedal device, in particular to a quick-release pedal device without tools. Background technique [0002] Today, the total amount of energy in the world is decreasing day by day, oil prices are rising, and the public is increasingly favoring green and environmentally friendly means of transportation. Bicycles bear the brunt, green, environmentally friendly, and fitness. Now governments around the world have launched free public bicycles, equipped with public transportation systems, and vigorously advocated green travel. This policy can also significantly relieve pressure during peak traffic congestion. Bicycles have become the new favorite of office workers. Folding bicycles have become very popular, and there are many styles of folding bicycles on the market. The volume of bicycle has been perplexing people's two big difficult problems all the time at present and is: 1, handlebar; 2, pedal. How to reduce the ...
