Abstract
The invention discloses a kind of ratchet mechanisms, including ratchet, mandrel and pawl, the inner ring of the ratchet is evenly arranged with the ratchet of odd number trace, the mandrel and coaxial ratchet are arranged, the pawl extends radially through along mandrel and is slidably connected to mandrel, when the root of pawl one end fitting ratchet, the length of the other end is less than or equal to mandrel to the distance of the tip of ratchet, greater than the distance of the root of mandrel to ratchet.Also disclose transmission mechanism, the breaker using the ratchet mechanism.Detent slide of the invention is connected to mandrel, is pushed by ratchet flexible, does not need elastic element, and structure is simplified, and is not easy stuck, improves reliability effectively.
Description
Technical field
The present invention relates to ratchet fields, and in particular to a kind of ratchet mechanism also relates to the transmission using the ratchet mechanism
Mechanism further relates to the breaker using the ratchet mechanism.
Background technique
A kind of one-way intermittent motion mechanism being made of ratchet and pawl, by engagement system be divided into external toothing ratchet mechanism and
Internal messing ratchet mechanism, wherein the basic structure of internal messing ratchet mechanism includes ratchet, mandrel and pawl, the inner ring of the ratchet
It is evenly arranged with several ratchet, the mandrel and coaxial ratchet are arranged, and pawl passes through the elastic mechanisms quilts such as spring or elastic piece
It overlays in ratchet, when the reverse ratchet direction of pawl rotates, meeting driving pawl rotation, the meeting when pawl is rotated along ratchet direction
It is streaked from ratchet, ratchet is stationary.
Due to increasing elastic mechanism so that the structure of pawl is more complicated, and the stability of elastic mechanism movement compared with
Low, pawl when being applied to the products such as breaker, will cause breaker to be failure to actuate there are stuck risk once pawl is stuck,
It may cause serious safety accident.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of ratchet mechanism, and using the ratchet mechanism transmission mechanism,
Breaker can solve the pawl of existing ratchet and be overlayed on ratchet using elastic mechanism, lead to that structure is complicated, and there are stuck wind
The problem of danger.
The invention is realized by the following technical scheme：
The inner ring of a kind of ratchet mechanism, including ratchet, mandrel and pawl, the ratchet is evenly arranged with the ratchet of odd number trace, institute
It states mandrel and coaxial ratchet is arranged, the pawl extends radially through and be slidably connected to mandrel along mandrel, when pawl one end is bonded
When the root of ratchet, the length of the other end is less than or equal to mandrel to the distance of the tip of ratchet, greater than the root of mandrel to ratchet
The distance in portion.
A kind of transmission mechanism using above-mentioned ratchet mechanism, the ratchet wheel are connected to pedestal front, and the mandrel passes through
Pedestal is worn, the pedestal back side is equipped with the rotary drive mechanism with mandrel transmission, is rotatably connected to rocking bar on the ratchet.
A kind of breaker using above-mentioned ratchet mechanism, the mandrel and electric-motor drive, the ratchet are connected by rocking bar
Connect the actuating mechanism of breaker.
A kind of breaker using above-mentioned transmission mechanism.
The advantages of the present invention over the prior art are that：
Detent slide is connected to mandrel, is pushed by ratchet flexible, does not need elastic element, and structure is simplified, and is not easy stuck, has
Effect improves reliability.
Detailed description of the invention
Fig. 1 is ratchet mechanism schematic diagram.
Fig. 2 is transmission mechanism schematic diagram.
