Abstract
The invention relates to a nut loosening prompting device. The device comprises a hexagonal nut body, rotary shafts, a pair of bending levers, a spring and small steel beads, and is characterized in that sunken planes are formed in two positions of the upper surface of the body, each sunken plane is connected with one rotary shaft, the rotary shafts are sleeved with one ends of the pair of bending levers, the other ends of the pair of rotary shafts can rotate around the shafts, one ends, close to the rotary shafts, of the bending levers are connected with the spring, a spherical sunken groove is designed in the other side end face of each sunken plane, commonly, a large part of the small steel beads are located in a spherical sunken groove of the body, and a small part of the small steel beads are located in spherical sunken grooves in one sides of the movable ends of the bending levers. The nut loosening prompting device has the advantages that when nuts loosen, the spring will eject the bending levers from the outer side of the edge of the nut body to prompt repairing or maintenance personnel to screw the nuts going loosening, and therefore harm and accidents are avoided; due to the fact that the mechanical prompting method is adopted, the prompt function can be achieved without needing external equipment and energy, and the device is economical, practical and high in generalization performance.
Description
Technical field
The present invention relates to the five metals electrical equipment, relate in particular to the nut loosening suggestion device.
Background technique
Nut on machine is easily loosening, if simple suggestion device is arranged, just can help maintenance or maintenance personnel to screw in time loosening nut, avoids the generation of harm and accident.
Summary of the invention
The present invention adopts following technological scheme, a kind of nut loosening suggestion device, comprise the hexagon nut parent, rotating shaft, the pair of curved lever, spring, little steel ball, described parent upper surface two places are with the depression plane, connect a rotating shaft on depression plane, every place, curved lever one end at two places is enclosed within rotating shaft, the other end can rotate around the axis, curved lever connects a spring near a side of rotating shaft, a bulb-shaped recess groove of design on depression another plane, plane, usual little steel ball major part is arranged in the bulb-shaped recess groove of parent, fraction is in the bulb-shaped recess groove of movable end one side of curved lever.
When nut screws, spring can not eject curved lever the outside, parent edge, because the barrier effect of little steel ball is arranged, but when nut loosening, little steel ball is very little to the resistance of curved lever, and spring can eject curved lever the outside, nut parent edge, prompting maintenance or maintenance personnel, screw loosening nut, avoid harm and accident to occur.
The invention has the beneficial effects as follows, owing to adopting the mechanical type prompting mode, need not can reach prompting function by external equipment and the energy, economical and practical, generalization is strong.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention
Wherein, 1-parent, 2-rotating shaft, 3-curved lever, 4-spring, 5-little steel ball.
Embodiment
Below in conjunction with accompanying drawing, be described in further detail.
As shown in Figure 1, a kind of nut loosening suggestion device, comprise hexagon nut parent 1, rotating shaft 2, pair of curved lever 3, spring 4, little steel ball 5, described parent 1 upper surface two places are with the depression plane, connect a rotating shaft 2 on depression plane, every place, curved lever 3 one ends at two places are enclosed within rotating shaft 2, the other end can rotate around axle 2, curved lever 3 connects a spring 4 near a side of rotating shaft, a bulb-shaped recess groove of design on depression another plane, plane, usual little steel ball 5 major parts are arranged in the bulb-shaped recess groove of parent 1, fraction is in the bulb-shaped recess groove of movable end one side of curved lever 3.
When nut screws, spring 4 can not eject curved lever 3 parent 1 outside, edge, and because the barrier effect of little steel ball 5 is arranged, but, when nut loosening, little steel ball 5 gives the resistance of curved lever 3 very little, and spring 4 can eject curved lever 3 nut parent 1 outside, edge.
The invention has the beneficial effects as follows: a kind of nut loosening suggestion device, when nut loosening, spring 4 can eject curved lever 3 nut parent 1 outside, edge, and prompting maintenance or maintenance personnel, screw loosening nut, avoids harm and accident to occur; Owing to adopting the mechanical type prompting mode, need not can reach the nut loosening prompting function by external equipment and the energy, economical and practical, generalization is strong.
