Abstract
The present invention discloses a kind of Chain wrench with tie-rod；The technical problem of solution：It is regular length that the chain of existing Chain wrench for being referred in background technology, which often saves, the circumferential size of different cylinder-like parts is not of uniform size, a certain distance be present in the chain section length of integer and the circumferential length of cylinder part, if both gaps are larger, chain just diminishes with cylinder part frictional force, and part is difficult the technical problem pulled down.The technical scheme of use：A kind of Chain wrench with tie-rod, including wrenching bar, chain, screw rod, nut, eave tile, sleeve and rubber sheet gasket.Nut and sleeve weld are on wrenching bar, and screw rod and eave tile hinge, chain one end are fixed on spanner boom end, and the other end passes through sleeve, hung on eave tile, rubber sheet gasket is fixed on wrenching bar.Advantage：This Chain wrench, the pulling force of screw acting is larger, and the frictional force of chain and part is big；By the fine setting of screw rod, spanner is set to be applied to the part of different circumferences.
Description
Technical field
The present invention relates to a kind of Chain wrench with tie-rod.
Background technology
Chain wrench is widely used in the dismounting and fastening work of cylinder-like part, and conventional Chain wrench relies on chain
The axle for often saving protrusion hangs tag on spanner, drives part to rotate using the frictional force between chain and part, but because chain often saves
It is regular length, the circumferential size of different cylinder-like parts is not of uniform size, the chain section length of integer and cylinder part
There is a certain distance in circumferential length, if both gaps are larger, chain just diminishes with cylinder part frictional force, and part is difficult to tear open
Under.
The content of the invention
The technical problems to be solved by the invention are：The chain of existing Chain wrench for being referred in background technology often saves
It is regular length, the circumferential size of different cylinder-like parts is not of uniform size, the chain section length of integer and cylinder part
There is a certain distance in circumferential length, if both gaps are larger, chain just diminishes with cylinder part frictional force, and part is difficult to pull down
Technical problem.
In order to solve the above technical problems, the technical solution adopted by the present invention is：
A kind of Chain wrench with tie-rod, including wrenching bar, chain, screw rod, nut, eave tile and sleeve,
Sleeve and nut are arranged on the outer surface of wrenching bar, set interval between sleeve and nut and sleeve is located at spiral shell
Female top；Screw rod is connected with nut thread, and eave tile is hinged on screw tip；One end of chain is arranged on the top of wrenching bar,
The other end of chain penetrates hub internal bore and hung on eave tile when in use.
Improvement to technical solution of the present invention, the rubber of frictional force is arranged to add on the upper end outer surface of wrenching bar
Pad.The further increasing friction force of rubber sheet gasket, the especially suitable and smooth part in surface.
Improvement to technical solution of the present invention, on the outer surface of wrenching bar, hub internal bore is vertically arranged sleeve weld.
Improvement to technical solution of the present invention, on the outer surface of wrenching bar, nut inner hole is vertically arranged nut-welding.
Compared with prior art, its advantage is the present invention：
1st, the Chain wrench with tie-rod of the invention, the pulling force of screw acting is larger, the frictional force of chain and part
Greatly.
2nd, the Chain wrench with tie-rod of the invention, by the fine setting of screw rod, makes spanner be applied to different circumferences
Part.
Brief description of the drawings
Fig. 1 is the structural representation with the Chain wrench of tie-rod.
Embodiment
Technical solution of the present invention is described in detail below, but protection scope of the present invention is not limited to the implementation
Example.
To make present disclosure more obvious understandable, further retouched below in conjunction with accompanying drawing 1 and embodiment
State.
In order to make the purpose , technical scheme and advantage of the present invention be clearer, it is right below in conjunction with drawings and Examples
The present invention is further elaborated.It should be appreciated that specific embodiment described herein is only to explain the present invention, not
For limiting the present invention.
Embodiment：
As shown in figure 1, be the Chain wrench with tie-rod of the present embodiment, including wrenching bar 1, chain 2, screw rod 3, spiral shell
Mother 4, eave tile 5 and sleeve 6.
Sleeve 6 and nut 4 are arranged on the outer surface of wrenching bar 1, and sleeve 6 is welded on the outer surface of wrenching bar 1, set
6 endoporus of cylinder are vertically arranged.Nut 4 is welded on the outer surface of wrenching bar 1, and the endoporus of nut 4 is vertically arranged.Sleeve 6 and nut 4 it
Between interval is set and sleeve 6 is located at the top of nut 4；Screw rod 3 is threadedly coupled with nut 4, and eave tile 5 is hinged on the top of screw rod 3；Chain
One end of bar 2 is arranged on the top of wrenching bar 1, and the other end of chain 2 penetrates the endoporus of sleeve 6 and hangs over eave tile 5 when in use
On.The rubber sheet gasket 7 of frictional force is arranged to add on the upper end outer surface of wrenching bar 1.Further increase rubs rubber sheet gasket
Wipe power, the especially suitable and smooth part in surface.
The application method of this Chain wrench：
By chain 2 around part one week, the free end of chain 2 passes through the endoporus of sleeve 6, and tension is articulated on eave tile 5, turns screw rod
3 further tense chain 2, the frictional force of increase chain 2 and part, and rotary spanner bar 1 is detachable block.
This uses the Chain wrench of tie-rod, and the pulling force of screw acting is larger, and the frictional force of chain and part is big；Pass through spiral shell
The fine setting of bar, spanner is set to be applied to the part of different circumferences.
Part that the present invention does not relate to is same as the prior art or can be realized using prior art.
As described above, although the present invention has been represented and described with reference to specific preferred embodiment, but it must not be explained
For to the limitation of itself of the invention., can be right under the premise of the spirit and scope of the present invention that appended claims define are not departed from
Various changes can be made in the form and details for it.
