Abstract
The utility model discloses a kind of chain block with rotational shell, including major axis, the lifting assembly and bangle wheel being placed on the major axis, is placed on the bangle wheel and pulls chain, and the rotational shell covered on the outside of the bangle wheel；The rotational shell rotationally with the lifting assembly or long axis connection；Offered on the rotational shell into chain hole and go out chain hole.The shell of rotational shell and lifting assembly is not integrative-structure in the utility model, but Split type structure, both can not separate, but it can relatively rotate, pull chain and pass through into chain hole and go out chain hole by pulling drive bangle wheel to rotate, so as to drive lifting assembly to lift by crane, when pulling chain oblique pull, rotational shell can also rotate, and be not in card chain phenomenon, will not more cause rotational shell to damage；The scope of application is wider, and service life is longer.
Description
Technical field
It the utility model is related to chain block field, more particularly to a kind of chain block with rotational shell.
Background technology
Chain block is a kind of simple, portable Manual hoisting instrument, mainly by pulling chain-driving hand wheel rotating, hand
Sprocket wheel drives major axis to rotate again, and major axis drives lifting assemblies to rotate again, so as to drive goods to lift by hoisting chain, completes
Weight.
Existing chain block is only used for just hanging use, i.e., the fixed hook of chain block is fixed aloft, passes through work
Dynamic lifting hook hangs up weight, completes the lifting to weight.Existing chain block chain case and chain only have one
Direction vertically pulls, once oblique pull occur card chain or damage case, so as to cause chain block can not normal use, it is right
When goods is laterally or diagonally drawn, existing chain block can not be then applicable.
Utility model content
The purpose of this utility model is to provide a kind of chain block with rotational shell, and it is once oblique to solve existing chain block
The problem of card chain or damage case occurs in drawing.
In order to solve the above technical problems, the utility model adopts the following technical scheme that：
A kind of chain block with rotational shell of the utility model, including major axis, the lifting assembly being placed on the major axis
With bangle wheel, it is placed on the bangle wheel and pulls chain, and the rotational shell covered on the outside of the bangle wheel；The rotation
Shell rotationally with the lifting assembly or long axis connection；Offered on the rotational shell into chain hole and go out chain hole.
Further, the case of the lifting assembly is straight with rotational shell with being provided with the rotational shell link position
The annular groove that footpath matches, annular nib is provided with the opening excircle of the rotational shell；The chimb nests into institute
State in groove, completion rotational shell is rotatably connected with lifting assembly.
Further, through hole is offered on the outer face of the rotational shell；The major axis end thread is connected with pressure
Set, the gland include circular platen；The diameter of the platen is more than the diameter of the through hole.
Further, it is described enter chain hole with it is described go out chain hole vertical range be equal to the bangle wheel diameter.
Further, standby chain hole is offered on the rotational shell.
Compared with prior art, advantageous effects of the present utility model are as follows：
The shell of rotational shell and lifting assembly is not integrative-structure in the utility model, but Split type structure, and both are not
It can separate, but can relatively rotate, pull chain and pass through into chain hole and go out chain hole by pulling drive bangle wheel to rotate, so as to drive
Dynamic lifting assembly lifting, when pulling chain oblique pull, rotational shell can also rotate, and be not in card chain phenomenon, will not more cause
Rotational shell damages；The scope of application is wider, and service life is longer.

Embodiment
As shown in Figure 1-2, a kind of one of which specific embodiment of the chain block with rotational shell, including major axis 1, set
In lifting assembly 2 and bangle wheel 3 on the major axis 1, it is placed on the bangle wheel 3 and pulls chain 4, and cover on the hand
The rotational shell 5 in the outside of sprocket wheel 3.The case of the lifting assembly 2 is with being provided with and rotating on the link position of rotational shell 5
The annular groove 8 that the diameter of shell 5 matches, annular nib 9 is provided with the opening excircle of the rotational shell 5；It is described convex
Side 9 is nested into the groove 8, and completion rotational shell 5 is rotatably connected with lifting assembly 2, makes rotational shell total with lifting
Into shell be connected, without departing from and can rotating.Symmetrically offered on the rotational shell 5 into chain hole 6 and go out chain hole
7, it is described enter chain hole 6 with it is described go out chain hole 7 vertical range be equal to the bangle wheel 3 diameter, make to pull the parallel pulling of chain,
Entering chain hole and go out chain hole can be by pulling " ten " byte of chain.As further optimization of the present utility model, the rotation
Shell 5 is offering two with entering chain hole and going out the standby chain hole of chain hole site relation identical, standby chain hole and it is original enter chain hole
It is the position that rotates to an angle with chain hole is gone out, when in use, enters chain hole and to go out chain hole because use for a long time causes when original
After serious wear, rotational shell 5 can be rotated, chain will be pulled and penetrated in two standby holes, be continuing with, it is outer due to rotating
The rotatability of shell 5, standby chain hole can also any rotation position, do not influence to use completely, can be significantly using such a mode
Degree ground extends service life of the present utility model.
As shown in Figure 1,3, a kind of another specific embodiment of the chain block with rotational shell, including major axis 1, are placed on
Lifting assembly 2 and bangle wheel 3 on the major axis 1, it is placed on the bangle wheel 3 and pulls chain 4, and covers on the bangle
The rotational shell 5 in the outside of wheel 3.Through hole 10 is offered on the outer face of the rotational shell 5, the rotational shell is fastened on institute
State on lifting assembly, with gland 11 through the through hole on rotational shell 5, be threadedly attached in the end of major axis 1.The pressure
Set 11 includes circular platen 12, and after gland is threaded on major axis, platen is pressed in rotational shell outside, the platen 12 it is straight
Footpath is more than the diameter of the through hole 10, fixes rotational shell and is fastened on lifting assembly, without departing from, and can turn
It is dynamic.Symmetrically offered on the rotational shell 5 into chain hole 6 and go out chain hole 7, it is described enter chain hole 6 with it is described go out chain hole 7 it is vertical
Distance be equal to the bangle wheel 3 diameter, make to pull the parallel pulling of chain, enter chain hole and go out chain hole can be by pulling chain
" ten " byte.As further optimization of the present utility model, the rotational shell 5 is offering two with entering chain hole and going out chain hole
The standby chain hole of position relationship identical, standby chain hole with it is original enter chain hole and to go out chain hole be the position to rotate to an angle, make
Used time, when it is original enter chain hole and go out chain hole due to for a long time use cause serious wear after, rotational shell 5 can be rotated, by hand
Zip strip is penetrated in two standby holes, is continuing with, and due to the rotatability of rotational shell 5, standby chain hole can also be any
Rotation position, does not influence to use completely, can significantly extend service life of the present utility model using such a mode.
Embodiment described above is only that preferred embodiment of the present utility model is described, not to of the present utility model
Scope is defined, and on the premise of the utility model design spirit is not departed from, those of ordinary skill in the art are new to this practicality
The various modifications and improvement that the technical scheme of type is made, the protection domain of the utility model claims book determination all should be fallen into
It is interior.
