Description
Technical field
It the utility model is related to a kind of spanner, specifically a kind of moment of torsion Novel socket wrench provided with alarm function.
Background technology
At present, spanner is existing in use often because the situation for causing bolt head to be twisted into two parts that overexerts occurs
Spanner with alarm function is mostly electronic alarming device, and this spanner price is relatively expensive.
The purpose of this utility model is to provide a kind of moment of torsion Novel socket wrench provided with alarm function.
The utility model will solve spanner existing for prior art often to be caused because overexerting in use
The situation that bolt head is twisted into two parts occurs, the existing relatively expensive problem of spanner price with alarm function.
Utility model content
The technical solution of the utility model is:A kind of moment of torsion Novel socket wrench provided with alarm function, including wrench body,
For double offset ring spanner at hand, described double offset ring spanner includes a mounting hole and accommodating cavity, described mounting hole at hand for described spanner one end
Connected with accommodating cavity, torsion circle is provided with described mounting hole, described torsion circle includes circle body and connection push rod, described circle
Body is placed in mounting hole, and described connection push rod is placed in accommodating cavity, and described connection push rod bottom is provided with jacking block, described top
Block bottom is provided with spring, and described double offset ring spanner is outside at hand to be provided with holddown plate, and described holddown plate is transparent holddown plate.
Described torsion circle can relatively rotate in mounting hole, and described circle body is formed in one structure with being connected push rod.
Described jacking block top is provided with an inclined-plane, and described inclined-plane is that left side is high, and right side is low, when connection push rod bottom is located at
When inclined-plane minimum point, in a state of nature, when push rod bottom is connected in not least, its spring is compressed spring,
When connection push rod is in inclined-plane peak, spring is maximum by compression, and spring is in and is effectively compressed scope, so as to prevent bullet
Spring is overly compressed and failed.
Described torsion circle inwall engages mouth for the polygon of fitted bolt head.
The beneficial effects of the utility model are：The utility model is simple in construction, can play alarm function, easy to use, and
Cost is low；Inside is provided with link stopper, effectively prevents part from overloading, while avoids spring-compressed of the present utility model excessive, causes bullet
Spring fails.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation that the utility model decomposes.
Fig. 3 is the structural representation of the utility model jacking block.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the utility model is described in further detail.
As illustrated, the utility model includes wrench body, it is characterised in that described spanner one end be double offset ring spanner at hand
2, described double offset ring spanner includes a mounting hole 10 and accommodating cavity 11 at hand, and described mounting hole 10 connects with accommodating cavity 11, described
Mounting hole 10 in be provided with torsion circle, described torsion circle includes circle body 1 and connects push rod 4, and described circle body 1 is placed in mounting hole
In 10, described connection push rod 4 is placed in accommodating cavity 11, and the described bottom of connection push rod 4 is provided with jacking block 8, under described jacking block 8
Portion is provided with spring 7.Described double offset ring spanner is outside at hand to be provided with holddown plate 12, described holddown plate is transparent holddown plate,
Therefore the displacement of connection push rod 4 can intuitively be seen.
Described torsion circle can relatively rotate in mounting hole, and described circle body is formed in one structure with being connected push rod.
The described top of jacking block 8 is provided with an inclined-plane, and described inclined-plane is that left side 5 is high, and right side 6 is low, when connection push rod 4 bottom
Positioned at when inclined-plane minimum point, spring 7 in a state of nature, when connecting the bottom of push rod 4 and being at not least, its spring quilt
Compression, when connecting push rod 4 and be in inclined-plane peak, spring 7 is by compression maximum, but spring 7 is still in being effectively compressed model
Enclose, so as to prevent that spring 7 is overly compressed and is failed.
Described torsion circle inwall engages mouth for the polygon of fitted bolt head.
Embodiment 1：The utility model patent is, for example, that bolt specification is M10*1.5P, and bolt grade is 8.8 grades, minimum
Breakdown torque is set to 66N.m, when the double offset ring spanner headgear on bolt when being exerted a force, due to the effect of power be it is mutual,
When being exerted a force from left to right to spanner, bolt can be to torsion circle from the right power that turn left, so as to drive torsion circle from right toward left-handed
Turn, the rotation of torsion circle drives connection push rod rotation, so as to which jacking block is by spring-compressed, when the power to spanner gradually increases, top
For block to spring-compressed is bigger, the swing offset of its torsion circle is bigger, because described holddown plate is transparent holddown plate, because
This can intuitively see the displacement of connection push rod, it is necessary to stop exerting oneself after connecting push rod and peaking at the peak on inclined-plane, if
Continue to exert oneself, now, bolt torque may be destroyed, because the utility model there is provided jacking block is ramp structure, so this reality
Even if not stopping applying external force with new, after connection push rod peaks at the peak on inclined-plane, its circle body would not be subjected to displacement, from
And prevent spring to be overly compressed and fail.
