Abstract

The utility model relates to a U-shaped force saving lever with a backward hook made of metal material. The utility model is characterized in that a segment of backward hook shaped resistance force arm is arranged on one end of the resistance force arm of the lever, a first buttonhole is arranged on the backward hook shaped resistance force arm and is connected with a U-shaped pulling rod, a second buttonhole is arranged at the front end of a U-shaped driving force arm positioned at on end of the driving force arm of the force saving lever, and is used for the fixation of the central shaft of the force saving lever; a third buttonhole is arranged at the back end of a U-shaped driving force arm positioned at on end of the driving force arm of the force saving lever, and is used for the fixation of a rolling bear; the backward hook U-shaped force saving lever is applicable for making circular movement on circular objects.

Description

Return the laborsaving lever of hook U-shaped

Affiliated technical field

The utility model relates to the laborsaving lever of hook U-shaped a kind of time.

Background technique

At present, people in live and work for convenience, the laborsaving lever of laborsaving use is varied, but according to the active force and the reaction force principle of circular object self gravitation, the special special pattern that returns the laborsaving lever of hook U-shaped that uses for the anodontia many tops of pulling band ear flywheel on circular shaft does not really exist.

Summary of the invention

In order to overcome the deficiency that the conventional laborsaving lever that uses when the circus movement object exists, the utility model a kind ofly returns the laborsaving lever of hook U-shaped by what metallic material was made for the anodontia many tops of pulling band ear flywheel is custom-designed.It is characterized in that: resistance arm one end at lever has one section resistance arm that returns hook-type, on the resistance arm head of time hook-type an eyelet is arranged, and is connected with the U-shaped pull bar; At laborsaving lever moving arm one end is the U-shaped power arm, at its front end individual eyelet is arranged, and is used for fixing laborsaving lever central shaft, and end has individual eyelet, is used for fixing rolling bearing; Returning the laborsaving lever of hook U-shaped is adapted at moving in a circle on the circular object, return the laborsaving lever of hook U-shaped under the self gravitation of circular object, the anodontia many tops of the reaction force pulling band ear flywheel that active force by when motion produces rotates, this reaction force along with the variation of the running speed of circular object in the constantly effect of expansion power.

The beneficial effects of the utility model are: according to the principle of object active force and reaction force, by the rotation of circular object, the U-shaped pull bar of resistance arm one end is connected with the anodontia many tops of band ear flywheel; Can produce active force to the power arm that returns the laborsaving lever of hook U-shaped when the circular shaft object rotates and resistance arm one end is produced reaction force acts, the resistance arm that returns the laborsaving lever of hook U-shaped can rotate by the anodontia many tops of reaction force pulling band ear flywheel, the anodontia many tops of band ear flywheel rotates the pulling axle and rotates, and axle is outwards exported power when rotating.

Below in conjunction with drawings and Examples the utility model is further specified:

Fig. 1 is a structural drawing of the present utility model

Fig. 2 is a connection diagram of the present utility model

1. times laborsaving levers of hook U-shaped among the figure, 2. time hook resistance arm, 3. balance pivot eyelet, 4. time hook resistance arm eyelet, 5. power arm eyelet, 6.U shape pull bar, 7.U shape pull bar eyelet, 8. eyelet.

Embodiment:

In Fig. 1, return the laborsaving lever of hook U-shaped (1), time hook resistance arm (2), balance pivot eyelet (3), return hook resistance arm eyelet (4), power arm eyelet (5), U-shaped pull bar (6), U-shaped pull bar eyelet (7), eyelet (8).

In the embodiment shown in Figure 2, the hook resistance arm eyelet (4) that returns that returns on the laborsaving lever of hook U-shaped (1) is connected with U-shaped pull bar eyelet (7); Eyelet (8) is connected with the anodontia many tops of band ear flywheel; Balance pivot eyelet (3) is used for fixing back the laborsaving lever of hook U-shaped.

Claims

A kind of time laborsaving lever of making by metallic material of hook U-shaped, it is characterized in that: resistance arm one end at lever has one section resistance arm that returns hook-type, on the resistance arm head that returns hook-type, an eyelet is arranged, be connected with the U-shaped pull bar, U-shaped power arm at laborsaving lever moving arm one end, its front end has individual eyelet, is used for fixing laborsaving lever central shaft; End has individual eyelet, is used for fixing rolling bearing; Returning the laborsaving lever of hook U-shaped is adapted at moving in a circle on the circular object.
