Abstract
The present invention relates to nut loosening suggestion device, including hex nut parent, rotating shaft, a pair of curved lever, spring, little steel ball, it is characterised in that：Recession plane is carried at the upper surface two of the parent, a rotating shaft is all connected with the recession plane often located, a pair of curved lever one end is enclosed within rotating shaft, the other end can rotate around the axis, curved lever connects a spring near one end of rotating shaft, a bulb-shaped recess groove is designed on another side end face of recession plane, little steel ball usually is predominantly located in the bulb-shaped recess groove of parent, and fraction is in the bulb-shaped recess groove of the movable end side of curved lever.The invention has the beneficial effects as follows：When nut loosening, spring can be pointed out on the outside of curved lever ejection nut parent edge maintenance or maintenance personnel, screw the nut of loosening, it is to avoid harm and accident occur；Due to using mechanical type prompting mode, without by external equipment and the energy, you can reach prompting function, economical and practical, generalization is strong.
Description
Technical field
The present invention relates to five metals electrical equipment, more particularly to nut loosening suggestion device.
Background technology
Nut on machine easily loosens, and if simple suggestion device, just can help keep in repair or maintenance personnel is timely
Screw the nut of loosening, it is to avoid harm and the generation of accident.
The content of the invention
The present invention adopts the following technical scheme that, a kind of nut loosening suggestion device, including hex nut parent, rotating shaft, one
To curved lever, spring, little steel ball, recession plane at the parent upper surface two, is carried, often locate to connect one on recession plane
Rotating shaft, the curved lever one end at two are enclosed within rotating shaft, and the other end can rotate around the axis, and curved lever connects near the side of rotating shaft
One spring, designs a bulb-shaped recess groove in another plane of recession plane, little steel ball usually is predominantly located in the spherical of parent
In recessed groove, fraction is in the bulb-shaped recess groove of the movable end side of curved lever.
During nut, spring will not eject curved lever on the outside of parent edge, because of the barrier effect for having little steel ball, but
When nut loosening, resistance very little of the little steel ball to curved lever, spring can eject curved lever on the outside of nut parent edge,
Prompting maintenance or maintenance personnel, screw the nut of loosening, it is to avoid harm and accident occur.
The invention has the beneficial effects as follows, due to using mechanical type prompting mode, without by external equipment and the energy, you can
Prompting function is reached, economical and practical, generalization is strong.
Description of the drawings
Fig. 1 is the structural representation of the present invention
Wherein, 1-parent, 2-rotating shaft, 3-curved lever, 4-spring, 5-little steel ball.
Specific embodiment
It is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of nut loosening suggestion device, including hex nut parent 1, rotating shaft 2, a pair of curved lever 3,
Spring 4, little steel ball 5, carry recession plane at 1 upper surface two of the parent, often locate to connect a rotating shaft 2 on recession plane, at two
3 one end of curved lever be enclosed within rotating shaft 2, the other end can be rotated around axle 2, curved lever 3 near rotating shaft side connect one
Spring 4, designs a bulb-shaped recess groove in another plane of recession plane, little steel ball 5 usually is predominantly located in the spherical female of parent 1
In sunken groove, fraction is in the bulb-shaped recess groove of the movable end side of curved lever 3.
During nut, spring 4 will not eject curved lever 3 on the outside of 1 edge of parent, because the stop for having little steel ball 5 is made
With, but when nut loosening, curved lever 3 can be ejected nut parent by resistance very little of the little steel ball 5 to curved lever 3, spring 4
On the outside of 1 edge.
The invention has the beneficial effects as follows：A kind of nut loosening suggestion device, when nut loosening, spring 4 can will bend thick stick
On the outside of 1 edge of the ejection nut of bar 3 parent, maintenance or maintenance personnel are pointed out, the nut of loosening is screwed, it is to avoid harm and accident are sent out
It is raw；Due to using mechanical type prompting mode, without by external equipment and the energy, you can reach nut loosening prompting function, Jing
Ji is practical, and generalization is strong.
