Embodiment 1

[0018] Embodiment one: see attached figure 1 And attached figure 2 shown. A two-way ratchet 4 mechanism for realizing the same or reverse rotation of the input shaft and the output shaft, including a bushing 1, an upper ratchet 2, a lower ratchet 3, a ratchet shaft 5 with a ratchet 4, and a reversing slider 6 and outer cover 7. Wherein, the shaft sleeve 1 is the input shaft of the two-way ratchet 4 mechanism, and the ratchet shaft 5 is the output shaft of the two-way ratchet 4 mechanism.

[0019] The shaft sleeve 1 is sleeved on the outside of the part of the ratchet shaft 5 that includes the ratchet 4, and has a slot on it. The upper pawl 2 and the lower pawl 3 are oppositely arranged in the slot on the shaft sleeve 1 and located at the center of the ratchet 4. sides. The upper ratchet 2 or the lower ratchet 3 respectively includes the claw tip close to the ratchet 4, the claw tail away from the ratchet 4 and the middle part between the claw tip and the claw tail, and th...

Abstract

The invention relates to a bothway ratchet mechanism. The bothway ratchet mechanism comprises a shaft sleeve, an upper pawl, a lower pawl, a ratchet shaft, a reversing sliding block and an outer cover, wherein the ratchet shaft is provided with a ratchet wheel, the shaft sleeve is provided with a slot, and the part, comprising the ratchet wheel, of the ratchet shaft is arranged in the shaft sleeve. The upper pawl and the lower pawl are oppositely arranged in the slot of the shaft sleeve and located on the two sides of the ratchet wheel. The upper pawl and the lower pawl are meshed with the ratchet wheel in the opposite directions. The reversing sliding block is arranged between the upper pawl and the lower pawl in a sliding mode and abuts against the upper pawl and the lower pawl. The outer cover is arranged outside the shaft sleeve in a sleeved mode and enables the reversing sliding block to be located between the upper pawl and the lower pawl. The outer cover is provided with a reversing groove, and part of the reversing sliding block is exposed out of the reversing groove. The shaft sleeve is an input shaft of the bothway ratchet mechanism, and the ratchet shaft is an output shaft of the bothway ratchet mechanism. According to the bothway ratchet mechanism, the input shaft and the output shaft of the bothway ratchet mechanism rotate in the same direction or the reverse directions, and the bothway ratchet mechanism is convenient and reliable to use and simple in structure .

Description

technical field [0001] The invention relates to a bidirectional ratchet mechanism for realizing the same or reverse rotation of an input shaft and an output shaft. Background technique [0002] In the application process of mechanical devices, it is often necessary to realize the mutual conversion between the input shaft and the output shaft rotating in the same direction or in the opposite direction. The structure of the existing devices for realizing the above functions is often relatively complicated, which brings a lot of inconvenience to production and use. Contents of the invention [0003] The object of the present invention is to provide a bidirectional ratchet mechanism with simple structure and convenient application to realize the same or reverse rotation of the input shaft and the output shaft. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A two-way ratchet mechanism, used to realize the same...
