Description
Technical field
The utility model relates to a kind of Fastener products, is specifically related to a kind of nut and gasket assembly.
background technique
In Fastener products, having a class is assembly parts product, comprise the assembly parts that nut and shim pack are fitted together, nut is for being generally outer-hexagonal nut, and pad can be spherical pad, flat pad or flute profile pad etc., its common structure is: be made up of hexagon nut and pad, the lower end surface of hexagon nut is provided with the endoporus of thin-wall shaft sleeve through described pad, and the lower end mouth of thin-wall shaft sleeve is provided with flanging described pad is riveted.Because nut and the pad of combinations thereof part are inseparable, and pad is easy to damage, and the pad function that particularly spherical pad or flute profile pad substantially can disappear original after using once or twice, so the waste causing is also considerable.In addition, the nut of this assembly parts does not possess the locking function of screw thread, because adopt nylon spacer locking, tinsel locking all can make structure become more complicated, is not too applicable to large batch of production and application.
Summary of the invention
In view of the problem that current known technology exists, the technical problems to be solved in the utility model is to be to provide one to have assembly parts and screw-threaded coupling function concurrently, and assembly parts can for convenience detachly be beneficial to nut and the gasket assembly of pad replacing simultaneously.
The utility model is implemented by the following technical programs:
Nut and gasket assembly, formed by hexagon nut and pad, the lower end surface of hexagon nut is provided with thin-wall shaft sleeve through the endoporus of described pad; the lower end mouth of thin-wall shaft sleeve is provided with flanging described pad is blocked; it is characterized in that: described flanging is provided with some flange breach; between adjacent flange breach, form flange gear leaf; described pad endoporus is provided with some endoporus and expands grooves; it is corresponding one by one with flange gear leaf that endoporus expands groove; endoporus expansion groove and flange keep off leaf just to time, pad frees in and out the cylindrical of thin-wall shaft sleeve.Described flange gear leaf arranges three equidistant places, and described endoporus expands groove three equidistant places are set equally, and the width of flange gear leaf is slightly less than the width of endoporus expansion groove.
Nut and the gasket assembly of technique scheme are adopted, first nut and pad can fit together to use and have same combination function with conventional nut gasket assembly, secondly pad can separate with nut, endoporus expand groove and flange keep off leaf just to time, pad can free in and out the cylindrical of thin-wall shaft sleeve, realize separating of pad and nut, thereby make assembly parts can for convenience detachly be beneficial to pad replacing.
In addition, for realizing the screw-threaded coupling function of nut, also adopt following technological scheme: described hexagon nut comprises the cylindrical body of outer-hexagonal body and outer-hexagonal body upper-end surface, tapped hole runs through outer-hexagonal body and cylindrical body, cylindrical cylindrical is offered the grooving of spiral trajectory, and grooving runs through inside and outside cylindrical body.
The working principle of above-mentioned screw-threaded coupling is: the setting of grooving can make cylindrical body compressive deformation in the axial direction, cause the original identical pitch of tapped hole also can change, in the time of the nut pitch that bolt is out of shape through cylindrical body tapped hole when mounted, its screw thread will be subject to certain effect of drawing of hanging up and down, increase threads turn frictional force, thereby make nut after screwing, there is screw-threaded coupling function.
Brief description of the drawings
The utility model has following accompanying drawing:
Fig. 1 is structural representation of the present utility model,
Fig. 2 be in Fig. 1 hexagon nut look up direction view,
Fig. 3 be Fig. 1 Intermediate gasket look up direction view.
Embodiment
Describe details and the working principle of the utility model specific embodiment in detail below in conjunction with accompanying drawing:
As shown in the figure, nut of the present utility model and gasket assembly, formed by hexagon nut 1 and 2 pads, the lower end surface of hexagon nut 1 is provided with the endoporus of thin-wall shaft sleeve 6 through described pad 2; lower end mouth of thin-wall shaft sleeve 6 is provided with flanging described pad 2 is blocked; described flanging is provided with three equidistant place's flange breach 8; between adjacent flange breach 8, form flange and keep off leaf 7; described pad 2 endoporus are provided with three equidistant place's endoporus and expand grooves 9; it is corresponding one by one with flange gear leaf 7 that endoporus expands groove 9, and the width of flange gear leaf 7 is slightly less than the width of endoporus expansion groove 9; Endoporus expand groove 9 and flange gear leaf 7 just to time, pad 2 frees in and out the cylindrical of thin-wall shaft sleeve 6, realizes separating of pad 2 and hexagon nut 1, makes assembly can for convenience detachly be beneficial to pad replacing.Described hexagon nut 1 comprises the cylindrical body 3 of outer-hexagonal body and outer-hexagonal body upper-end surface, tapped hole 4 runs through outer-hexagonal body and cylindrical body 3, the cylindrical of cylindrical body 3 is offered the grooving 5 of spiral trajectory, grooving 5 runs through inside and outside cylindrical body 3, the width of grooving 5 is in 2-2.5mm left and right, the setting of grooving 5 can make cylindrical body 3 compressive deformation in the axial direction, cause the original identical pitch of tapped hole 4 at cylindrical body 3 centers also can change, in the time of the nut tapped hole 4 that bolt is out of shape through cylindrical body when mounted, its screw thread will be subject to certain effect of drawing of hanging up and down, increase threads turn frictional force, thereby make nut after screwing, there is screw-threaded coupling function.
