Abstract
The utility model provides a disc ratchet device which comprises the following components: a supporting frame, a ratchet which is sleeved on the supporting frame, a rotating handle which is arranged above the ratchet and is sleeved on the supporting frame, and a pawl which is arranged on the rotating handle. The rotating handle is provided with a pressing block. The disc ratchet device provided by the utility model has the following advantages: reasonable design, firm structure, reliable operation, high operation efficiency, convenient operation, reduced potential safety hazard, and convenient use.
Description
Technical field
The utility model relates to mechanical engineering, especially disk ratchet unit.
Background technique
Ratchet mechanism, a kind of one-way intermittent motion mechanism being formed by ratchet and pawl, ratchet mechanism is commonly used in the transposition of various lathes and the feeding of automaton discontinuous or rotary table, is also commonly used on jack.In bicycle, ratchet mechanism is for unidirectional drive, and in hand-operated winch, ratchet mechanism is conventional in case non-return turning.On ratchet, all can be provided with the ratchet gear teeth, the ratchet gear teeth are used unidirectional tooth conventionally, and ratchet is articulated with on rocking bar, when rocking bar counterclockwise swings, drive ratchet just to insert hook tooth to promote ratchet rotating in same direction; When rocking bar clockwise direction swings, ratchet slips on ratchet, and ratchet stops operating, and current ratchet or need a ratchet be used for stirring ratchet also has a corresponding non-return ratchet to be used for preventing ratchet reversion; Need two ratchets to cooperatively interact again or exactly and stir ratchet, no matter adopting which kind of form all to need to be provided with two ratchets could normally work, will seem like this and waste a little resource, and present ratchet is all fixed by screw, although structure is more firm, screw can be aging, will easily split away off, can reduce working efficiency, use inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of disk ratchet unit easy to use, well-set.
For solving above-mentioned existing technical problem, the utility model adopts following scheme: disk ratchet unit, comprise supporting frame, be enclosed within ratchet on supporting frame, be located at the rotating handles that is enclosed within above ratchet on supporting frame, be located at the ratchet on rotating handles, described rotating handles is provided with briquetting.
As preferably, described ratchet is done corresponding rotation along with the promotion of ratchet, cooperatively interact, reasonable in design.
As preferably, described ratchet is connected on rotating handles, the unnecessary trouble that can avoid screw to get rusty coming off and bring.
As preferably, on described ratchet, be evenly provided with some and draw-in groove click-fit work, ratchet can promote ratchet by draw-in groove and rotate.
Beneficial effect:
The utility model has adopted technique scheme that disk ratchet unit is provided, and has made up the deficiencies in the prior art, reasonable in design, sound construction, and reliable operation, working efficiency is high, easy to operate, reduces potential safety hazard, uses safety.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, disk ratchet unit, comprise supporting frame 1, be enclosed within ratchet 2 on supporting frame 1, be located at ratchet 2 and be enclosed within rotating handles 3 on supporting frame 1 above, be located at the ratchet 4 on rotating handles 3, described rotating handles 3 is provided with briquetting 5, described ratchet 2 is done corresponding rotation along with the promotion of ratchet 4, described ratchet 4 is connected on rotating handles 3, is evenly provided with some and draw-in grooves 5 ratchet 4 cooperatings on described ratchet 2.
During real work, on supporting frame 1, cover has ratchet 2, above ratchet 2, be provided with a rotating handles 3, on rotating handles 3, clamping is provided with ratchet 4, reduced screw, effectively avoid coming off because screw gets rusty, on rotating handles 3, be also provided with the briquetting 5 supporting with ratchet 4, can effectively avoid in process that ratchet 4 rotates at ratchet 2 jitter amplitude excessive and ratchet 2 is caused to damage, rotating handles 3 carrys out back rotation, drive ratchet 4 rotations, ratchet 4 will promote ratchet 2 and rotate, the utility model only adopts a ratchet to drive, effectively reduced the consumption of resource, increased working efficiency, easy to use.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
