Description
Technical field
This utility model relates to the chain-type Lever Blocks of a kind of band ratchet fixing device, is a kind of lifting appliance, is mainly used in power construction repairing.
Background technology
For work high above the ground, common Lever Blocks and chain-type chain block weight lay particular stress on, and operator carry the shortcoming of difficulty, we have developed a kind of portable chain-type aluminium alloy chain block；Particularly easy to operate when power construction repairing adjusts conducting wire sag, lightweight, the more traditional calabash of folding and unfolding chain is fast；Traditional chain-type chain block during using, single direction ratchet all the time will spacing by unidirectional ratchet, therefore the most laborsaving during folding and unfolding chain, the most smooth and easy.
Utility model content
This utility model purpose is to provide one to can solve the problem that the above-mentioned problems in the prior art, and provides a kind of Stability Analysis of Structures, and safety is laborsaving, the chain-type Lever Blocks of folding and unfolding band ratchet fixing device smoothly.
This utility model purpose is achieved through the following technical solutions:
A kind of chain-type Lever Blocks of band ratchet fixing device, including ratchet spanner assembly, gear-driven assembly, chain, fixation hook, main body cover and suspension hook holder assembly, ratchet spanner assembly includes single direction ratchet and unidirectional ratchet, single direction ratchet is followed handle under the effect of unidirectional ratchet and is kept one direction clockwise to rotate, unidirectional ratchet includes card increment and locking end, in unidirectional ratchet, reduction torsion spring is installed, unidirectional ratchet remains that under the effect of reduction torsion spring its card increment and single direction ratchet fit, it is characterized in that, also include ratchet stator and fixing screw, described ratchet stator is fixed on main body cover by fixing screw, ratchet stator is flexure strip, the locking end position of unidirectional ratchet can be blocked by the card convex that ratchet stator front end folds, card increment is made to depart from single direction ratchet.
As preferably, also including sprocket shaft end cap, pad and split pin, described sprocket shaft end cap is solid on main body cover, and sprocket shaft end cap upper end cylinder is equipped with unidirectional ratchet, pad and split pin.
As preferably, described reduction torsion spring one end is contained in sprocket shaft end cap, and the other end is contained in unidirectional ratchet front end.
As preferably, described ratchet stator is fixed screw by interior hexagonal cylindrical head and is fixed on sprocket shaft end cap by certain angle.
Compared with prior art, this product has the advantage that this product limits the position of unidirectional ratchet by ratchet stator, and single direction ratchet is spacing without unidirectional ratchet, eliminates the restriction of external force, and folding and unfolding chain is quick, laborsaving.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present embodiment.
Fig. 2 is single direction ratchet in Fig. 1, unidirectional ratchet, reduction torsion spring, sprocket shaft end cap, pad and the partial exploded view of split pin.
Label declaration: ratchet spanner assembly 1, single direction ratchet 11, unidirectional ratchet 12, card increment 121, locking end 122, reduction torsion spring 13, sprocket shaft end cap 14, pad 15, split pin 16, gear-driven assembly 2, chain 3, fixation hook 4, main body cover 5, suspension hook holder assembly 6, ratchet stator 7, card convex 71, fixing screw 8, two-way ratchet 9, handle 10.
Detailed description of the invention
Illustrate that this utility model, the following example are merely to illustrate the technical solution of the utility model below in conjunction with specific embodiment, do not limit protection domain of the present utility model.
Embodiment:
nullAs illustrated in fig. 1 and 2，The product of the present embodiment includes ratchet spanner assembly 1、Gear-driven assembly 2、Chain 3、Fixation hook 4、Main body cover 5 and suspension hook holder assembly 6，The annexation of said structure belongs to the technology being disclosed，Therefore do not launch to say，Ratchet spanner assembly 1 includes single direction ratchet 11 and unidirectional ratchet 12，Single direction ratchet 11 is followed handle 10 under the effect of unidirectional ratchet 12 and is kept one direction clockwise to rotate，Unidirectional ratchet 12 includes card increment 121 and locking end 122，In unidirectional ratchet 12, reduction torsion spring 13 is installed，Unidirectional ratchet 12 remains that under the effect of reduction torsion spring 13 its card increment 121 and single direction ratchet 11 fit，The present embodiment also includes ratchet stator 7 and fixing screw 8，Ratchet stator 7 is fixed on main body cover 5 by fixing screw 8，Ratchet stator 7 is flexure strip，Locking end 122 position of unidirectional ratchet 12 can be blocked by the card convex 71 that ratchet stator 7 front end folds，Card increment 121 is made to depart from single direction ratchet 11.
The present embodiment also includes sprocket shaft end cap 14, pad 15 and split pin 16, sprocket shaft end cap 14 is solid on main body cover 5, it is equipped with unidirectional ratchet 12, pad 15 and split pin 16 on the cylinder of sprocket shaft end cap 14 upper end, wherein reduction torsion spring 13 one end is contained in sprocket shaft end cap 14, and the other end is contained in unidirectional ratchet 12 front end；And ratchet stator 7 fixed screw 8 by interior hexagonal cylindrical head and is fixed on sprocket shaft end cap 14 by certain angle.
During actually used, when needs quickly retracting chain 3, pressing ratchet stator 7, then pulling the unidirectional ratchet 12 of rotation makes itself and single direction ratchet 11 depart from, and make its afterbody locking end 122 be fully rotated into above the ratchet stator 7 being pressed, unclamping the ratchet stator 7 of pressurized, it upwards resets under the effect of elastic force, ratchet stator 7 front end the card convex 71 folded is by the position locking of unidirectional ratchet 12；After two-way ratchet 9 is transferred to central idle, now single direction ratchet 11 be no longer influenced by unidirectional ratchet 12 unidirectional force constraint, the two-way ratchet 9 being connected on handle also becomes disengaged position with bidirectional ratchet；Chain 3, chain 3 meeting band movable sprocket and gear sheet, bidirectional ratchet and single direction ratchet 11 is now pulled quickly to rotate together with gear shaft.Pulling suspension hook holder assembly 6 end chain 3 for putting chain, pull the chain 3 in safety collar direction for receiving chains, operation now, due to spacing without unidirectional ratchet 12 of single direction ratchet 11, eliminates the restriction of external force, and folding and unfolding chain 3 is quickly, laborsaving.
The several specific embodiments being only the application disclosed above, but the application is not limited to this, the changes that any person skilled in the art can think of, all should fall in the protection domain of the application.
