Detailed description of the invention
As Figure 1-3, the mini Lever Blocks that a kind of gearless rotates, including body 1 and the lifting of aluminum alloy material
Axle 2；Described jack shaft 2 is erected in described body 1 rotationally.Sprocket wheel portion 201 that described jack shaft 2 includes being sequentially connected with,
Separating part 202 and major axis portion 203, these three parts are formed in one, in sprocket wheel portion coiling hoisting chain drive weight rise or
Declining, separating part is the round boss that diameter is more than pilot hole diameter, and it is described sprocket wheel portion that major axis portion is used for coordinating wrench assembly
Rotational power is provided.Described body 1 includes pilot hole 3, is penetrated by jack shaft in pilot hole, makes the jack shaft can be in pilot hole
Rotate；Described sprocket wheel portion 201 is through described pilot hole 3, and described separating part 202 is stuck on described pilot hole 3, described major axis portion
203 are positioned at described pilot hole 3 opposite side.Ratchet it is arranged with successively near described separating part 202 one end in described major axis portion 203
4 and brake disc 5, described ratchet 4 both sides are respectively provided with friction plate 6, described brake disc 5 with described major axis portion 203 for threadeding,
Arranging interior T-shaped screw thread in brake disc, the free end in major axis portion arranges outer T-shaped screw thread, and brake disc is rotated in major axis portion, completes week
To fixing, two described friction plates 6 are pressed on described separating part 202 with described ratchet 4, formally realize jack shaft,
Friction plate, ratchet and brake disc are integrated, and are synchronized with the movement.Wrench assembly 7, described major axis portion 203 it is arranged with in described brake disc 5
Free end on offer screwed hole 8, described major axis portion 203 end assemble band plain washer 9 screw 10 by described spanner
Assembly 7 is fixed in the circumference of described brake disc 5, drives disc rotation by pulling wrench assembly.Arrange on described body 1
The ratchet 11 coordinated with described ratchet 4, described ratchet 11 is had to be rotatably mounted to the installing hole 13 of body 1 by detent pin 12
In, described detent pin 12 is also arranged with ratchet spring 14, the reaction force acts of described ratchet spring 14 is at described ratchet 11
On, making ratchet 11 be stuck on described ratchet 4, ratchet has the tooth of deflection counterclockwise, ratchet is stuck on tooth, due to ratchet
Turn clockwise, then ratchet is pushed up on teeth directional, makes ratchet to rotate, but ratchet rotates counterclockwise, and ratchet props up tooth, makes ratchet
Cannot rotate, make ratchet to turn clockwise, but can not rotate counterclockwise.
The most in addition hook assembly is installed on body top, this Lever Blocks can be hanging to fixed position.
As shown in Figure 4, specifically, described brake disc 5 includes ring flange 501 and brake body 502；Described ring flange 501
Side acts on described friction plate 6, is provided with two butterfly pads 15, prevents pine between opposite side and described wrench assembly 7
Dynamic.
It is provided with spring washer 16 between described plain washer 9 and described screw 10 termination, prevents screw loosening.
Described detent pin 12 sequentially passes through the through hole of described ratchet 11, described ratchet spring 14 and described installing hole 13, separately
One end is fixed by nut, makes ratchet can rotate in detent pin, and one end of ratchet spring acts on ratchet, keeps ratchet
The normality engaged with ratchet, when ratchet rotates clockwise, ratchet is by the nib contacts of jack-up Yu the tooth of ratchet, when ratchet is counterclockwise
During rotation, ratchet inserts in tooth under the effect of elastic force, prevents ratchet from turning round.Freely turn when needing ratchet (related jack shaft)
Time dynamic, risen by pawl plate, then ratchet can be freely rotatable.
Embodiment described above is only that the optimal way to the present invention is described, and not carries out the scope of the present invention
Limiting, on the premise of designing spirit without departing from the present invention, technical scheme is made by those of ordinary skill in the art
Various deformation and improvement, all should fall in the protection domain that claims of the present invention determines.
