The various shapes such as locking supporting plate 11 square, rectangle, ellipse.
Bearing 13 has a supporting plane 131, and a holder through-hole 132 is opened on supporting plane 131,
The aperture of block hole 132 more than the external diameter of nut body 121, and holder through-hole 132 be dimensioned to block
Base plate 123 and locking supporting plate 11.
Supporting plane 131 at least a pair opposite side is downwardly extending two sides, and the height of two sides is more than
The thickness of base plate 123, so that nut 11 can carry out the movement of vertical direction in bearing 13.Each
The lower end of side is at least provided with a pedestal 134, and when thereby may be ensured that welding, captive nut assembly is flat
Face degree, makes captive nut assembly be easily installed simultaneously.
Holder through-hole 132 periphery is provided with at least one antiseized agnail 133, in case electrophoresis liquid adhesion.It is preferred that
Holder through-hole 132 periphery is provided with the antiseized agnail 133 that even number is uniformly arranged, the wherein antiseized agnail of half 133
Protruding upward, to prevent the electrophoresis liquid between locking supporting plate 11 lower surface and bearing 13 outer surface bonding, another
Half antiseized agnail 133 is downwardly projecting, to prevent the electrophoresis between bearing 13 inner surface and base plate 123 upper surface
Liquid is bonding.
Nut body 121 passes from the lower section of holder through-hole 132, the supporting plate through hole 111 of nut supporting plate 11 and spiral shell
Locking supporting plate tooth 122 interference fit that parent 121 upper end is peripheral, thus by nut body 121 and nut supporting plate
11 lockings are integrated.Owing to having interval between locking supporting plate tooth 122 lower end and base plate 123 upper surface, and
The height of side is more than the thickness of base plate 123, such that it is able to make nut 12 vertical together with nut supporting plate 11
Move on direction.Again owing to the aperture of holder through-hole 132 is more than the external diameter of nut body 121, spiral shell can be made
Female 11 move together with nut supporting plate 11 in the horizontal direction.Nut supporting plate 11 is by holder through-hole simultaneously
132 block so that nut 12 can not come off from the lower section of bearing 13；Base plate 123 is blocked by holder through-hole 132
Live so that nut 12 can not come off from the top of bearing 13.It is to say, nut 12 can in level and
Vertical direction moves without coming off.
In preferred embodiment of the present utility model, nut 12 is T-nut, three of supporting plane 131
Extend separately down and form two long side faces 135 and a short side 136, the welding of short side 136
Salient point 134 is positioned in the middle of the lower end of short side 136, and the pedestal 134 in long side face 135 lays respectively at
The lower end in long side face 135 close minor face opening part.Holder through-hole 132 periphery is provided with four uniform arrangements
Antiseized agnail 133, two relative antiseized agnails 133 raise up, and other two antiseized agnail 133 is downward
Protruding.
The captive nut assembly 1 of locking supporting plate provided by the utility model, nut 12 is reprocessed conveniently, when
When bearing 13 is easy to open, can directly be reprocessed by replacing nut 12；When bearing 13 is inconvenient to open,
Owing to nut 12 sidewall is thicker, can return to attack by screw thread and reprocess.
