The product of the utility model is simple in structure rationally, through setting up the transition fluted disc, can realize when drawing the heavy object, it is laborsaving greatly.

Description

Hand winch

Technical field

The utility model belongs to jacking equipment technical field, is related to a kind of hand winch.

Background technology

Hand winch, also known as hand winch, is a kind of mechanical appliance, and it is pulling goods by shaking with hands niggerhead Thing.The winch cable reel driven by gear pulls goods by rotating the steel wire rope that is wound on above it.It is light and firm Gu, steel construction is suppressed in plating, and wirerope pulls the unit of pulley propulsion by two default jaws.These jaws capstan winch to Cable is pulled when premode, while an and automatic brake system.Jaw can be locked when grip increases automatically Firmly.Hand winch can also be used to be lifted（Lifting force for dilatory force 65% or so）.Existing capstan winch adopts two radius differences Gear be meshed, this capstan winch extract some heavier-weights object when, still cause high effort for.

The content of the invention

The utility model is directed to the problems referred to above, there is provided a kind of hand winch, when the capstan winch extracts weight, very laborsaving.

According to the technical solution of the utility model：A kind of hand winch, it is characterised in that：Including support, rotate on support First axle, the second axle, the 3rd axle are set, and block plate is fixed in first axle one end, and the other end is fixed driven fluted disc, fixed on the second axle Disk is crossed, driving gear disc on the 3rd axle, is fixed, second axle is placed between first axle and the 3rd axle, transition fluted disc and driven fluted disc And driving gear disc is engaged simultaneously.

Used as further improvement of the utility model, the 3rd axle outer end is fixedly connected handle.

Used as further improvement of the utility model, the radius of the driven fluted disc is more than the radius of transition fluted disc, transition Radius of the radius of fluted disc more than driving gear disc.

It is of the present utility model to have technical effect that：The utility model product structure advantages of simple, by arranging transition fluted disc, Can realize when weight is extracted, it is significantly laborsaving.

Description of the drawings

Fig. 1 is structural representation of the present utility model.

Left views of the Fig. 2 for Fig. 1.

Specific embodiment

Below in conjunction with the accompanying drawings specific embodiment of the present utility model is further described.

In Fig. 1, including support 1, first axle 2, the second axle 3, the 3rd axle 4, block plate 5, driven fluted disc 6, transition fluted disc 7, master Active toothed disk 8, handle 9 etc..

As shown in figure 1, the utility model is a kind of hand winch, including support 1, rotate on support 1 arrange first axle 2, Second axle 3, the 3rd axle 4,2 one end of first axle fix block plate 5, and the other end is fixed driven fluted disc 6, fixes transition disc on the second axle 3 7, fix driving gear disc 8 on the 3rd axle 4, second axle 3 is placed between first axle 2 and the 3rd axle 4, transition fluted disc 7 with it is driven Fluted disc 6 and driving gear disc 8 are engaged simultaneously.

3rd axle, 4 outer end is fixedly connected handle 9, and the radius of driven fluted disc 6 is more than the radius of transition fluted disc 7, transition fluted disc 7 Radius more than driving gear disc 8 radius.

The course of work of the present utility model is as follows：When weight is extracted, weight is passed through into steel cable or chain and 2 phase of first axle Connection, and fix, handle 9 is rotated, handle 9 drives driving gear disc 8 to rotate, and driving gear disc 8 drives transition in rotation process Fluted disc 7 is rotated, and transition fluted disc 7 drives driven fluted disc 6 to rotate, and driven fluted disc 6 drives first axle 2 to rotate, due to driven fluted disc 6 Radius of the radius more than transition fluted disc 7, the radius of transition fluted disc 7 are more than the radius of driving gear disc 8, in initial rotation handle 9, The power for only needing to very little can just pull very heavy weight.
