Abstract
The utility model discloses a ratchet wheel mechanism capable of changing rotation direction. A ratchet wheel tooth socket (11) on a ratchet wheel (3) is rectangular, i.e. the two side faces of the ratchet wheel tooth socket (11) are straight baffle surfaces which are parallel mutually. The front end of a pawl (5) is structured with two intersecting flat surfaces, wherein one surface is a straight baffle surface for blocking, and the other surface is an inclined surface for slipping. When the technical scheme is used, the pawl is the direct insertion pawl, the tail end of the pawl is a handle for facilitating pulling out the pawl to change the limiting direction. The limiting rotation direction of a turntable can be selected randomly, and the operation for changing the limiting direction of the pawl is simple. The pawl can rebound after 90-degree rotation when the pawl is pulled out, the pawl can not enter into the ratchet wheel tooth socket, and the free rotation of the ratchet wheel in two directions can be realized by canceling the blocking function. The ratchet wheel mechanism disclosed by the utility model is simple in structure and convenient in operation.

Embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and working principle, the manufacturing process of the mutual alignment between the shape of embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technological scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 1, Fig. 2, be a kind of ratchet mechanism that changes gyratory directions, comprise rotary disk 2, fixed tray 4 and positioning shaft 1, ratchet 3 is fixed on the described rotary disk 2, and ratchet 5 is installed on the described fixed tray 4 by ratchet positioning seat 8.
In order to solve the problem that exists at the described present known technology of this specification background technique part and to overcome its defective, realize the selection of two gyratory directions of ratchet, make its unidirectional rotation, oppositely card ends, can also realize the free rotating goal of the invention of ratchet, the technological scheme that the utility model is taked is:
The ratchet mechanism that changes gyratory directions provided by the utility model, the ratchet teeth groove 11 on the described ratchet 3 be shaped as rectangle, the bi-side of promptly described ratchet teeth groove 11 are straight block face parallel to each other; The structure of the fore paw end of described ratchet 5 is the structure of two Plane intersects, and wherein one side is ended the straight block face that acts on for card lifting, and another side has been the plane of inclination of the effect of skidding.
In order to realize the optional function that turns to, the utility model changes slat belt ratchet of the prior art into direct insertion ratchet, ratchet 5 is extracted the back Rotate 180 ° rebound, and ratchet 5 sticks into ratchet teeth groove 11 in the other direction, and ratchet 3 can rotate in the opposite direction; Ratchet 5 is extracted the back half-twist rebound, ratchet 3 does not stick into ratchet teeth groove 11, can realize cancelling the function that the card of 5 pairs of ratchets 3 of ratchet ends, and can cancel ratcher function, makes the rotating disk can forward and reverse any rotation.The rotatable direction of rotating disk can be selected arbitrarily; Ratchet is when changing the restriction sense of rotation, and cancellation restriction simple to operate when turning to.
The front end of ratchet 5 described in the utility model is cylindrical, with the pilot hole of described ratchet positioning seat 8 be Spielpassung.The front end of ratchet 5 adopts cylindrical configuration, its objective is its rotation for convenience, so that realize 180 ° or 90 ° of ratchet 5 revolutions, reaches above-mentioned effect.
The rear end of ratchet 5 described in the utility model is provided with handle 7, described handle 7 is connected with ratchet 5 by handlebar, between the endoporus of described handlebar and described ratchet positioning seat 8, be provided with spring 6, described spring 6 is a stage clip, and the direction of its elastic force is to make described ratchet 5 press to described ratchet 3.
The tail end design handle of ratchet 5 is to extract ratchet 5 for convenience, realizes changing spacing direction; Keeping elastic mechanism, is in order to make ratchet 5 can stick into ratchet teeth groove 11 well.
Handlebar on the handle 7 described in the utility model is provided with it and laterally is connected locating stud 10, described ratchet positioning seat 8 has two handle locating slots 9 towards the back end design of described handle 7, and the locating stud 10 on described handle locating slot and the handlebar forms Spielpassung.
The tail end of ratchet 5 passes spring 6 backs and is connected with handle 7.The back end design of ratchet positioning seat 8 has two handle locating slots 9, and is identical with locating stud 10 positions on the handle 7.Said structure can make ratchet 5 limit forward and reverse rotation and clockwise and anticlockwise rotates freely this two kinds of conversion of operation state at rotating disk.
Use operating method of the present utility model:
After extracting handle 7, locating stud 10 breaks away from handle locating slots 9, decontrols behind handle 7 Rotate 180s °, and under the effect of spring 6, ratchet 5 falls into ratchet teeth groove 11 again.Because the fore paw end of ratchet 5 is the structure that stop surface is spacing, skid in the another side angle of inclination on one side, so just changed the direction of the prevention rotation of rotary disk 2 behind ratchet 5 Rotate 180s °.
If will decontrol behind handle 7 half-twists, ratchet 5 will can not fall into ratchet teeth groove 11, only can skid in the outer of ratchet 3, therefore can realize cancelling the unidirectional rotation of ratchet 3, oppositely block the function of ending, and rotary disk 2 can rotate arbitrarily.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technological scheme carry out; or design of the present utility model and technological scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
