Abstract
The invention provides a precision fastening nut. The precision fastening nut comprises an outer ring column, wherein the contour line of the cross section of the outer ring column is polygon shaped. The inner side of the outer ring column comprises an inner ring column, wherein the cross section of the inner ring column is circle shaped. The inner ring face of the inner ring column is provided with a thread. A radial plate of the inner ring column extends outside in the radial direction. The surface of the radial plate is provided with a piezoelectric patch in an adhered mode. The radial plate and the piezoelectric patch are arranged into a radial groove of the outer ring column in a clamped mode. The piezoelectric patch is electrically connected with a light emitting diode of the outer ring column. According to the precision fastening nut, during the fastening process, the precision tightness degree is achieved.
Description
Technical field
The present invention relates to hardware field, especially, relate to a kind of tightening nut.
Background technique
Nut is the basic part in hardware, is mainly used in carrying out fastening to link; In the actual using process of tightening nut, user usually can be screwed to stubborn motionless till; But in some occasion, the degree of tightening for tightening nut limits to some extent, if too pine can cause it to come off, and if too tight, then likely damage link; Moreover, at the link of some regular dismounting, if twist too tight, also will be unfavorable for very much that the later stage dismantles; Therefore, these occasions all need the elasticity of nut to be screwed to lucky benefit, and current nut, for new hand, obviously more difficult assurance sense of propriety.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide a kind of accurate tightening nut, this accurate tightening nut in fastener cycle, can realize accurate elasticity.
The technical solution adopted for the present invention to solve the technical problems is: it is polygonal outer annulated column that this accurate tightening nut comprises cross section outer profile; Comprising a cross section inside described outer annulated column is circular interior annulated column; The inner ring surface of described interior annulated column is shaped with screw thread, and on interior annulated column radially side extend one piece of radial plate, described radial plate surface has been sticked one piece of piezo-electric sheet; Described radial plate is fastened in the radial groove of described outer annulated column together with piezo-electric sheet; Described piezo-electric sheet is electrically connected the light emitting diode on described outer annulated column.
As preferably, in the electrical connection path of described piezo-electric sheet and light emitting diode, be connected in series a slot, described slot comprises two jacks that can insert for Zener diode; After Zener diode inserts this slot, described piezo-electric sheet, Zener diode, light emitting diode form series loop.
As preferably, described interior annulated column is made up of metal, and described outer annulated column is made up of vitreous humor, and described light emitting diode is located in the hole slot of vitreous humor inside.
Beneficial effect of the present invention is: this accurate tightening nut is in rundown process, dynamics of tightening directly reacts in the compression degree of described piezo-electric sheet, screwing force is larger, then the instantaneous output voltage of piezo-electric sheet is higher, after output voltage exceedes the blanking voltage of light emitting diode, namely light emitting diode is lit; Therefore, Proper Match light emitting diode, when light emitting diode can be made just to be lit, screwing force is just right, and namely now the elasticity of tightening nut is just right.
Accompanying drawing explanation
Fig. 1 is embodiment one schematic diagram of this accurate tightening nut.
Fig. 2 is embodiment two schematic diagram of this accurate tightening nut.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment one shown in Fig. 1, it is polygonal outer annulated column 1 that this accurate tightening nut comprises cross section outer profile; Comprising a cross section inside described outer annulated column 1 is circular interior annulated column 2; The inner ring surface of described interior annulated column 2 is shaped with screw thread, and on interior annulated column 2 radially side extend one piece of radial plate 21, described radial plate 21 surface has been sticked one piece of piezo-electric sheet 3; Described radial plate 21 is fastened in the radial groove 10 of described outer annulated column 1 together with piezo-electric sheet 3; Described piezo-electric sheet 3 is electrically connected the light emitting diode 4 on described outer annulated column 1.
Above-mentioned accurate tightening nut, in order to make external structure bright and clean brief, described interior annulated column 2 is made up of metal, and described outer annulated column 1 is made up of vitreous humor, and described light emitting diode 4 is located in the hole slot of vitreous humor inside.
This accurate tightening nut is in rundown process, dynamics of tightening directly reacts in the compression degree of described piezo-electric sheet 3, and screwing force is larger, then the instantaneous output voltage of piezo-electric sheet 3 is higher, after output voltage exceedes the blanking voltage of light emitting diode 4, namely light emitting diode 4 is lit; Therefore, Proper Match light emitting diode 4, when light emitting diode 4 can be made just to be lit, screwing force is just right, and namely now the elasticity of tightening nut is just right.
For the embodiment two shown in Fig. 2, the difference of itself and embodiment one is: described piezo-electric sheet 3 is with the electrical connection path of light emitting diode 4, also be connected in series a slot 5, described slot 5 comprises two jacks that Zener diode (not shown) can be supplied to insert; After Zener diode inserts this slot 5, described piezo-electric sheet 3, Zener diode, light emitting diode 4 form series loop.
Wherein, described Zener diode reversal connection is in described series loop, when the output voltage of piezo-electric sheet 3 is below the breakdown reverse voltage of Zener diode, all the time electric current is not had in series loop, and output voltage is when reaching the breakdown reverse voltage of Zener diode, series loop is switched on instantaneously, light emitting diode 4 instant igniting, is easier to the critical fastening force distinguishing nut; Meanwhile, the Zener diode of grafting different model in described slot 5, can be used for this nut in the operating mode of different fastening force.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, all should be included within protection scope of the present invention.
