Description
Technical field
The present invention relates to a kind of spanner, specifically a kind of alarm function torque wrench equipped with transparent holddown plate.
Background technique
Currently, spanner is in use often because overexert the case where causing bolt head to be twisted into two parts, it is existing
Spanner with alarm function is mostly electronic alarming device, and this spanner price is relatively expensive.
The object of the present invention is to provide a kind of alarm function torque wrenches equipped with transparent holddown plate.
The invention solves spanners of the existing technology often to lead to bolt because overexerting in use
The case where head is twisted into two parts, the existing relatively expensive problem of spanner price with alarm function.
Summary of the invention
The technical scheme is that a kind of alarm function torque wrench equipped with transparent holddown plate, including spanner sheet
Body, at hand for double offset ring spanner, the double offset ring spanner includes a mounting hole and accommodating cavity, the installation at hand for described spanner one end
Torsion circle is equipped in hole, the torsion circle lower part is equipped with jacking block, and the jacking block is placed in accommodating cavity side, the accommodating cavity
The other side is equipped with spring, and the spring one end peaks on jacking block, and the other end peaks on the inner wall of accommodating cavity；The jacking block
The torsion circle for the position that rear end is intersected with torsion circle is equipped with arrow；The double offset ring spanner is external at hand to be equipped with clamping cap
Plate；The holddown plate and double offset ring spanner uses screw connection at hand, and the holddown plate is made of transparent material.
The torsion circle can relatively rotate in mounting hole, and the torsion circle is an integral molding structure with jacking block.
The mounting hole is connected to accommodating cavity, is shelves point on the right side of the position of the connection, and the accommodating cavity is
" ﹄ " structure, " ﹄ " structure upper have certain length.
The shelves point is greater than or equal to the distance of spring maximum compression to the distance of the inner wall on the right side of accommodating cavity, thus
Prevent that spring is overly compressed and is failed.
The torsion circle inner wall is that the polygon of fitted bolt head engages mouth.
The invention has the benefit that the configuration of the present invention is simple, can play alarm function, it is easy to use and at low cost；It is interior
Portion is equipped with shelves point, effectively prevent part to overload, while avoiding spring-compressed of the invention excessive, leads to spring failure.

Specific embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described.
As shown, the present invention includes wrench body 1, described 1 one end of spanner is double offset ring spanner at hand 8, the plum blossom
Driving end 8 includes a mounting hole 6 and accommodating cavity 12, is equipped with torsion circle 7 in the mounting hole 6,7 lower part of torsion circle is set
There is jacking block 10, the jacking block 10 is placed in 12 side of accommodating cavity, and 12 other side of accommodating cavity is equipped with spring 9, the bullet
9 one end of spring peaks on jacking block 10, and the other end peaks on the inner wall of accommodating cavity 12, and the holddown plate is transparent material system
At.
The torsion circle 7 can relatively rotate in mounting hole 6, and the torsion circle 7 and jacking block 10 are integrally formed knot
Structure.
The mounting hole 6 is connected to accommodating cavity 12, is shelves point 11, the accommodating cavity on the right side of the position of the connection
12 be " ﹄ " structure, and " ﹄ " structure upper has certain length S1.
The shelves point 11 to the right side of accommodating cavity 12 inner wall distance S be greater than or equal to 12 maximum compression of spring away from
From so that spring 12 be prevented to be overly compressed and fail.After spring reaches maximum compression, due to the effect of shelves point 11, jacking block 10
It is no longer displaced, so that spring 12 be prevented to be overly compressed and fail.
The double offset ring spanner is external at hand to be equipped with holddown plate 2.
The holddown plate 2 uses screw 4 to connect at hand with double offset ring spanner.
7 inner wall of torsion circle is that the polygon of fitted bolt head engages mouth.The polygonized structure of 7 inner wall of torsion circle
As common spanner interior wall construction.
The invention patent according to the specification of bolt, special bolt wear special grade, torque spanner, for example, bolt advises
Lattice are M10*1.5P, and bolt grade is 8.8 grades, and minimum breakdown torque is set as 66N.m, when the double offset ring spanner headgear is on bolt
When force, due to the effect of power be mutually, when turn left to spanner from the right side exert a force when, bolt can be to torsion circle from a left side
The power turned right, so that torsion circle be driven to rotate from left to right, the rotation of torsion circle drives jacking block rotation, so that jacking block is by spring pressure
Contracting, when the power to spanner is gradually increased, jacking block is to bigger by spring-compressed, and the swing offset of torsion circle is bigger, indicator
Head will be moved constantly from left to right, since holddown plate is made of transparent material, can constantly see the state of spring-compressed, arrow
The movement of head position is moved to when can not exert a force range indicating area it is necessary to stop exerting oneself, such as from the range indicating area that can exert a force
Fruit continues to exert oneself, and arrow locations will be moved into limit range indicating area, at this point, bolt torque may be destroyed, due to this hair
It is bright to be provided with shelves point, although after jacking block peaks at shelves point, position would not occur for jacking block so the present invention is regardless of applying external force
It moves, due to being equipped with shelves point, so being overly compressed and failing invention prevents spring.
Since holddown plate is made of transparent material, the state of spring-compressed can be constantly seen, to prevent from destroying spiral shell
Bolt torque.
