There is screw thread, the two sides of the screw hole are evenly arranged with radiating area, and the inside of the radiating area is evenly arranged with radiating fin, described
The two sides of nut interior are provided with enhancement layer, and the inside of the enhancement layer is evenly arranged with the second reinforcing rib.
Preferably, the side wall of the nut is evenly arranged with reset spring, and the nut is connected by reset spring and shell
It connects, stretching structure is constituted by reset spring between the shell and nut.
Preferably, the side wall of the nut is provided with Vinylidene Chloride corrosion-resistant coating.
Preferably, the welding hole is symmetrical about the vertical center line of nut.
Preferably, the waterproof pad and screw hole are distributed in concentric circles.
Preferably, second reinforcing rib is equally distributed.
Compared with prior art, the utility model has the beneficial effects that the captive nut is structurally reasonable, have following excellent
Point:
It 1,, can be effective when bolts and nuts are mutually tightened by being internally provided with the first reinforcing rib in shell
The intensity of shell is improved, outdoor class is not likely to produce deformation, while by being provided with enhancement layer in nut, uniformly setting in enhancement layer
It is equipped with the second reinforcing rib, further improves the structural strength of this captive nut, it is steady when cooperating with each other bolt and nut
It is qualitative higher.
2, by being provided with reset spring between shell and nut, when bolt is not to timing, squeeze screw hole make nut into
Row fine tuning, after removing bolt, nut can't restore to original position, and reset spring can help nut to keep in the center at this time.
3, by being provided with stabilizer blade, stabilizer blade is internally provided with welding hole, can be welded by welding hole, facilitate fixation
The position of shell, so that bolt be facilitated to carry out to the stability just, also improved after fixing.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Please refer to Fig. 1-4, a kind of embodiment provided by the utility model: a kind of captive nut, including shell 1, nut 2,
Screw hole 3 and stabilizer blade 12, the middle position inside the shell 1 are provided with nut 2, and the side wall of the nut 2 was provided with chlorine
Ethylene corrosion-resistant coating, the service life of hoisting nut 2, the side wall of the nut 2 are evenly arranged with reset spring 7, the nut 2
It is connect by reset spring 7 with shell 1, stretching structure is constituted by reset spring 7 between the shell 1 and nut 2, facilitates spiral shell
