Abstract
The utility model discloses an one -way gear, comprising a gear body, be equipped with the blind hole in the middle of the gear body, be equipped with a plurality of screens grooves along the circumference on the pore wall of blind hole, install ratchet in the blind hole, ratchet includes two parallels and spaced's cylinder body, be equipped with a plurality of movable ratchets that match with the screens groove along the circumference between two cylinder bodies, the activity ratchet passes through the articulated shaft and articulated fixing is realized to two cylinder bodies, and it has the arc hole to open on the activity ratchet, the arc hole uses the articulated shaft as the centre of a circle, still is equipped with spacing axle between two cylinder bodies, spacing axle passes the arc hole, the cylinder body is equipped with the shaft hole along the axis. The utility model discloses an one -way gear, the structure of adoption activity ratchet, when anticlockwise rotation, owing to during the activity ratchet is in the interval between two cylinder bodies, do not have the effort with the blind hole inner wall, so the noise of production is little, it is also little to wear and tear.
Description
Technical field
The utility model relates to a kind of ratchet.
Background technology
At present, ratchet has all obtained vast application in all trades and professions. Existing ratchet, in the time that driven wheel does not rotate, the noise that its internal structure produces is large, and wearing and tearing are large, and maintenance cost is high.
Summary of the invention
It is large that the utility model will solve existing ratchet operation noise, the technical problem that maintenance cost is high.
The technical scheme in the invention for solving the above technical problem is:
A kind of ratchet, comprises gear body, in the middle of described gear body, is provided with blind hole, on the hole wall of described blind hole, is provided with multiple screens grooves along circumference; In described blind hole, ratchet mechanism is installed, described ratchet mechanism comprises two cylindrical bodies parallel and place at interval, between described two cylindrical bodies, be provided with multiple movable ratchets that mate with screens groove along circumference, described movable ratchet is realized hinged fixing by jointed shaft and two cylindrical bodies, on movable ratchet, have arcuate socket, described arcuate socket, taking jointed shaft as the center of circle, is also provided with limit shaft between two cylindrical bodies, and described limit shaft is through arcuate socket; Described cylindrical body is provided with axis hole along axis.
The outer wall of described cylindrical body is provided with multiple oil storage tanks.
Described cylindrical body diameter is less than blind hole diameter.
The technique effect that the utility model can reach is:
Compared with prior art, ratchet of the present utility model, the structure of employing activity ratchet, while clockwise rotating cylindrical body, due to the effect of centrifugal force, movable ratchet and the intrinsic screens groove of gear are realized clamping and are driven, while rotating counterclockwise, movable ratchet is subject to the restriction of blind hole, rotates rotation to the interval between two cylindrical bodies around jointed shaft, simultaneously, be subject to the effect of limit shaft, movable ratchet remains on rational position, while having ensured to turn clockwise, can at once be rotated in place along with the effect of centrifugal force, with the screens of screens groove; In the time rotating counterclockwise, in the interval of movable ratchet between two cylindrical bodies, there is not active force with blind hole inwall, so the noise of generation is little, wear and tear also little.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model ratchet.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, the utility model provides a kind of ratchet, comprises gear body 1, in the middle of described gear body 1, is provided with blind hole 2, on the hole wall of described blind hole 2, is provided with multiple screens grooves 3 along circumference; In described blind hole 2, ratchet mechanism is installed, described ratchet mechanism comprises two cylindrical bodies 4 parallel and place at interval, between described two cylindrical bodies 4, be provided with multiple movable ratchets 5 that mate with screens groove 3 along circumference, described movable ratchet 5 is realized hinged fixing by jointed shaft 6 and two cylindrical bodies 4, on movable ratchet 5, have arcuate socket 7, described arcuate socket 7, taking jointed shaft 6 as the center of circle, is also provided with limit shaft 8 between two cylindrical bodies 4, and described limit shaft 8 is through arcuate socket 7; Described cylindrical body 4 is provided with axis hole 9 along axis.
The outer wall of described cylindrical body 4 is provided with multiple oil storage tanks 10.
Described cylindrical body 4 diameters are less than blind hole 2 diameters.
Operation principle of the present utility model is as follows:
Ratchet of the present utility model, be applicable to any field that needs one-way operation, while clockwise rotating cylindrical body 4, owing to being subject to the effect of centrifugal force, movable ratchet 5 rotates around jointed shaft 6, and scatter with gear body 1 in screens groove 3 realize clamping, like this, just can rotate by driven wheel body 1, in the time rotating counterclockwise cylindrical body 4, movable ratchet 5 is subject to the effect of the hole wall of blind hole 2, rotate and rotate to the interval between two cylindrical bodies 4 around jointed shaft 6, lose the driving effect to gear body 1, simultaneously, be subject to the effect of limit shaft 8, movable ratchet 5 remains on rational position, while having ensured to turn clockwise, can at once be rotated in place along with the effect of centrifugal force, with 3 screens of screens groove.
The ratchet above the utility model embodiment being provided is described in detail, applied specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment is just for helping to understand the technical scheme that the utility model discloses; , for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model meanwhile.
Claims (3)
