Abstract
The utility model discloses a kind of assembled spanners, feature be include polygon spanner, bolt and wrenching bar, the side of polygon spanner is provided with the bayonet for grip bolt or nut, other every one side of polygon spanner is provided with the spanner bar jack for wrenching bar insertion, the upper surface of polygon spanner is provided with several wrenching bar location holes corresponding with wrenching bar jack position, wrenching bar fixation hole is provided on the front end anchor ring of wrenching bar, bolt is sequentially inserted into wrenching bar location hole and wrenching bar fixation hole, polygon spanner is mutually connected and fixed with wrenching bar, advantage is by adjusting wrenching bar position, it can get the space further tightened, and then apply prestressing force, it may be implemented in spanner at limited space to be not necessarily to re-registrate the operation that can continue to tighten nut.
Description
Technical field
The utility model relates to a kind of spanners, more particularly, to a kind of assembled spanner.
Background technique
In prestressed reinforcement of tensioning, jack and sleeve can be generally used, needs spanner protruding into sleeve after tensioning
Avris manually tightens nut, and sleeve avris opening range is fixed, and common wrench rotates nothing behind a part of space in operation
Method carries out next step operation again.Existing spanner is to be substantially to be integrally machined in the market, general spanner and to pull between body be solid
Fixed, position and angle between the two is fixed, and when use need to cover spanner on nut, and rotation pulls body to turn nut, but
When the screw that need to be fixed is in the limited position of the space angles such as crack, the space that spanner can rotate is limited, need to rotate
Spanner is taken out after certain angle, is changed after wrench position re-registrates and is continued to rotate in rotatable space, tightens a spiral shell
Above-mentioned movement need to be repeated several times in silk, and the nut after being likely to result in spanner and turning in a limited space in can not be into
Row contraposition, continues subsequent operation.
Summary of the invention
It may be implemented in spanner at limited space the technical problem to be solved by the utility model is to provide one kind to be not necessarily to again
Contraposition can continue to tighten the adjustable assembled spanner in wrenching bar position of nut.
Technical solution adopted by the utility model to solve the above technical problems is as follows: a kind of assembled spanner, including it is polygon
Shape spanner, bolt and wrenching bar, the side of the polygon spanner is provided with the bayonet for grip bolt or nut, described
Other every one side of polygon spanner be provided with the spanner bar jack being inserted into for the wrenching bar, the polygon
The upper surface of spanner is provided with several wrenching bar location holes corresponding with the wrenching bar jack position, the wrenching bar
Front end anchor ring on be provided with wrenching bar fixation hole, the bolt is sequentially inserted into the wrenching bar location hole and described pulls
In hand lever fixation hole, the polygon spanner is mutually connected and fixed with the wrenching bar.
The torus shape of the wrenching bar is identical as the inner wall shape of spanner bar jack, the ring of the bolt
The inner wall shape of face shape, the inner wall shape of the wrenching bar location hole and the wrenching bar fixation hole is identical.
The material of the polygon spanner, the bolt and the wrenching bar is steel.
Compared with the prior art, the advantages of the utility model are: a kind of adjustable dress in wrenching bar position of the utility model
With formula spanner, by the spanner bar jack of wrenching bar insertion polygon spanner side when use, rotated after being fixed with bolt
It operates, continues rotation process after bolt and wrenching bar to be inserted into new hole location after rotation certain space, be not necessarily to spanner and nut
It is relocated.In actual operation, screw up with a wrench nut, when wrenching bar is limited by jack sleeve portion, passes through tune
Whole wrenching bar position can get the space further tightened, and then apply prestressing force, it can be achieved that spanner is not necessarily at limited space
Re-registrate the operation that can continue to tighten nut.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model assembled spanner；
Fig. 2 is the separate structure schematic diagram of the utility model assembled spanner；
Fig. 3 is the schematic diagram of wrench position when the utility model assembled spanner turns nut in actual operation；
Fig. 4 is that the utility model assembled spanner adjusts the schematic diagram behind wrenching bar position in actual operation；It is wherein more
Side shape spanner -1, bolt -2, wrenching bar -3, bayonet -4, wrenching bar location hole -5, wrenching bar fixation hole -6, spanner bar jack -7,
Jack sleeve -8, nut -9.
Specific embodiment
The utility model is described in further detail below in conjunction with figure embodiment.
Specific embodiment
A kind of assembled spanner, as depicted in figs. 1 and 2, including polygon spanner 1, bolt 2 and wrenching bar 3, polygon is pulled
First 1 side is provided with the bayonet 4 for grip bolt or nut, and other every one side of polygon spanner 1 is provided with confession
The spanner bar jack 7 that wrenching bar 3 is inserted into, it is corresponding with 7 position of spanner bar jack that the upper surface of polygon spanner 1 is provided with several
Wrenching bar location hole 5, wrenching bar fixation hole 6 is provided on the front end anchor ring of wrenching bar 3, it is fixed that bolt 2 is sequentially inserted into wrenching bar
In position hole 5 and wrenching bar fixation hole 6, polygon spanner 1 is mutually connected and fixed with wrenching bar 3.
In this particular embodiment, the torus shape of wrenching bar 3 is identical as the inner wall shape of spanner bar jack 7, bolt 2
The inner wall shape of torus shape, the inner wall shape of wrenching bar location hole 5 and wrenching bar fixation hole 5 is identical.Polygon spanner 1,
The material of bolt 2 and wrenching bar 3 is steel.
Application method is as follows: wrenching bar 3 can be inserted into any one spanner bar jack 7, make the spanner on polygon spanner 1
Wrenching bar fixation hole 6 on bar location hole 5 and wrenching bar 3 is aligned, and bolt 2 is sequentially inserted into wrenching bar location hole 5 and wrenching bar
In fixation hole 6, further polygon spanner 1 is mutually connected and fixed with wrenching bar 3.Spanner is protruded into jack from side when use
In sleeve 8, bayonet 4 can be matched with nut 9, push wrenching bar 3 to turn nut 9 counterclockwise, when shifting the position that can not be operated onto
When locating (as shown in Figure 3), hole location position as shown in Figure 4 is reinserted after wrenching bar 3 is taken out, continuation carries out above-mentioned behaviour counterclockwise
Make, until nut 9 is tightened, 3 work angle of wrenching bar can not be limited by the open sided space of jack sleeve 8 in operating process
System, acquisition further tightens space, it can be achieved that spanner is without re-registrating the behaviour that can continue to tighten nut 9 at limited space
Make.
Above-described embodiment is the further explanation to the utility model, but the protection scope of the utility model is with claim
Subject to book.
