Background

In the 21 st century, science and technology are rapidly developed, and people are more and more careful in mechanical research; the demand for machinery is also becoming more dependent; by a compact and smart mechanical structure; people can do many things with machines; the structure of the machine is thus greatly excavated.

At present, a ratchet device is taken as a common mechanical mechanism in life, is often applied to mechanical equipment such as bicycles and the like, and is used for preventing gears from rotating, so that unnecessary loss and faults are caused, and the research and development of the ratchet device by human beings are never stopped.

However, most ratchet devices in the market still achieve the purpose of preventing the ratchets from rotating through gravity.

Disclosure of Invention

The invention aims to solve the problem that the existing ratchet device is not stable enough, and provides a stable ratchet device.

In order to realize the purpose of the invention, the invention adopts the following technical scheme:

a stabilizing ratchet assembly, comprising: comprises a ring sleeve 1, a ratchet 2 and a rotating shaft column 3; the ring sleeve 1 is also provided with a ratchet locking buckle 11, a ratchet reset pad 12, a magnetic ring 13 and an outer frame 14; the ratchet locking buckle 11 is made of magnetic materials; a rotating shaft through hole 141 is further formed in the center of the outer frame 14; the rotating shaft column 3 is movably sleeved in the rotating shaft through hole 141;

the ratchet locking buckle 11 is matched with the ring sleeve 1 through hinge connection, the ratchet resetting pad 12 is arranged on the inner side of the ring sleeve 1 and specifically positioned between the ring sleeve 1 and the ratchet locking buckle 11, the magnetic ring 13 is arranged on the outer side and/or the inner side of the ring sleeve 1, the ratchet locking buckle 11 is attracted by the magnetic force of the magnetic ring 13 and is close to the side of the magnetic ring 13, but is blocked by the ratchet resetting pad 12, so that an angle of N degrees is stably kept between the ratchet locking buckle 11 and the ring sleeve 1;

the ratchet wheel 2 is provided with ratchet wheel teeth 21; the ratchet 2 is sleeved on the rotating shaft column 141; the ratchet teeth 21 are matched with the ratchet locking buckle 11.

As preferred in the present invention: the value of N is influenced by the height of the ratchet reset pad 12 and the distance of the ratchet reset pad 12 from the hinge point of the ratchet lock 11 and the collar 1.

As preferred in the present invention: the ratchet wheel reset pad 12 has elasticity, when the ratchet wheel locking buckle 11 reversely passes through the ratchet wheel teeth 21, because the ratchet wheel reset pad 12 has elasticity, the ratchet wheel locking buckle 11 cannot generate overlarge friction force with the ratchet wheel teeth 21, so that the ratchet wheel locking buckle 11 and the ratchet wheel teeth 21 are better protected, the service lives of the ratchet wheel locking buckle 11, the reset spring 5 and the ratchet wheel teeth 21 are prolonged, noise is reduced, the use performance is improved, and the rebound is quicker.

As further preferred in the present invention: the ratchet wheel 2 is also provided with oblique gear teeth 22; the helical gear teeth 22 are adapted to fit an external machine gear.

Compared with the prior art, after the technical scheme is adopted, the method has the following beneficial effects:

a special ratchet structure can not interfere the operation of the special ratchet structure no matter the ratchet structure is used in a side or reverse way or is interfered by external factors such as vibration and the like.

And secondly, the application scene can be improved by adding oblique gear teeth.

And thirdly, the abrasion degree of the ratchet wheel structure can be reduced to the maximum extent, and the ratchet wheel structure has super-strong stability and durability.

Fourth, under the premise of the same size, the number of the ratchet teeth and the same ratchet locking buckle, the ratchet locking buckle is adapted to larger torque force, because each ratchet assembly is more stable and is not influenced by gravity and object placement; each ratchet wheel component can play a role, so that a stronger ratchet wheel effect is provided; avoid only a small part of ratchet wheel to be stressed, resulting in structure damage.

Fifthly, the ratchet wheel assembly is enabled to be more silent, noise is reduced, and the ratchet wheel assembly can be used in quiet places.

Sixthly, different fillers are adopted, and the effects of the fillers are different, so that the actual ratchet effect is changed; such as: the slow rebound filler is adopted, so that the interference of the ratchet wheel to the rotating wheel is reduced when the rotating wheel runs at a high speed; thereby increasing the rotating speed of the rotating wheel, and the fast rebound of the filler can more quickly enable the ratchet wheel to be matched.

The invention only discloses an annular ratchet structure, but a linear ratchet structure can also adopt the structure of the invention, so that the linear ratchet structure can be stably used in any state, while the traditional ratchet mechanism adopts a linear type, can only be horizontally placed and cannot be placed upside down, otherwise, the ratchet is ineffective and must be limited at a certain angle.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Example (b):

a stabilising ratchet device as shown in figures 1 to 5, wherein: comprises a ring sleeve, a ratchet wheel and a rotating shaft column. The ring sleeve is also provided with a ratchet locking buckle, a ratchet reset pad, a magnetic ring and an outer frame. The ratchet locking buckle is made of magnetic material. The center of the outer frame is also provided with a rotating shaft through hole. The rotating shaft column is movably sleeved in the rotating shaft through hole.

The ratchet locking buckle and the ring sleeve are matched through hinge connection, the ratchet resetting pad is arranged on the inner side of the ring sleeve and is specifically positioned between the ring sleeve and the ratchet locking buckle, the magnetic ring is arranged on the outer side and/or the inner side of the ring sleeve, the ratchet locking buckle is attracted by the magnetic force of the magnetic ring and is drawn close to the side of the magnetic ring but is blocked by the ratchet resetting pad, and therefore an angle of N degrees is stably kept between the ratchet locking buckle and the ring sleeve.

The ratchet wheel is provided with ratchet wheel teeth. The ratchet wheel is sleeved on the rotating shaft column. The ratchet teeth are matched with the ratchet locking buckle.

In order to adapt to various adaptation requirements in real life, the value of the N can be adjusted according to actual requirements, and the value of the N is influenced by the height of the ratchet reset pad and the distance between the ratchet reset pad and the hinge joint of the ratchet locking buckle and the ring sleeve.

In order to better protect the ratchet locking buckle and the ratchet teeth, the service life of the ratchet locking buckle, the reset spring and the ratchet teeth is prolonged, noise is reduced, the use performance is improved, the ratchet reset pad rebounds faster and has elasticity, and when the ratchet locking buckle can reversely pass through the ratchet teeth, the ratchet reset pad has elasticity, so that overlarge friction force cannot be generated between the ratchet locking buckle and the ratchet teeth.

In order to adapt to more application scenes in life, the ratchet wheel is further provided with oblique gear teeth. The helical gear teeth are adapted to the external mechanical gear.
