Description
Technical field
The utility model is related to nut for automobile fields, and in particular to a kind of acorn nut.
Background technology
Acorn nut is exactly hex nut with a lid as its name suggests, its effect of this lid is exactly that fastening outside is exposed
Part covers, and prevents moisture or some other corrosive substance from entering the inside to play the role of antirust, and then improve it
The usage time of body and connector.
But in actual use, still there can be certain gap between traditional acorn nut and work piece interface,
Have no stopping function simultaneously.
Utility model content
Based on the above issues, the utility model aim is that providing one kind having sealing performance, prevents dirt from entering screw thread,
And the acorn nut with retaining effect.
In view of the above problems, providing following technical solution：A kind of acorn nut, including nut, the nut are in hexagonal
Shape, described nut one end are equipped with hemispherical end cap, and the nut is equipped with internal thread relative to one end of hemispherical end cap, described interior
Glue bead is equipped in screw thread, the glue bead is spherical in shape and boring, the glue bead are equipped with gum-injecting port, have in the glue bead close
Sealing, the gum-injecting port are equipped with sealing cover, and the gum-injecting port passes through towards hemispherical end cap between the glue bead and internal thread
Transition cooperation is fixed and is located at internal thread hole bottom, the internal thread that the distance between the glue bead and internal thread aperture are 0.5 to 1 times
Major diameter.
In above structure, by the way that glue bead is arranged in internal thread, squeezed by bolt end when nut is threaded onto on bolt
Glue bead makes its broken release fluid sealant, as the screw-in of nut makes fluid sealant squeeze to entire screw-thread fit face and nut and zero
On part contact surface, to realize sealed waterproof effect, while there is certain retaining effect.
The utility model is further arranged to, and the glue bead is brittle plastic material.
In above structure, brittle plastic material is crushed convenient for glue bead when being squeezed.
The utility model is further arranged to, and the fluid sealant is 704 fluid sealants.
The utility model is further arranged to, and the nut is equipped with the support turned up relative to one end of hemispherical end cap
Edge.
In above structure, support edge can increase the contact area between nut and parts, reduce contact stress.
The utility model is further arranged to, if the support edge end face is evenly equipped with arterial highway locking tooth.
In above structure, locking tooth can not only realize the retaining of nut, but also can enter adjacent stop when fluid sealant is squeezed
The gap blocked between tooth between locking tooth is moved back, dirt is avoided to enter locking tooth.
The beneficial effects of the utility model：By the way that glue bead is arranged in internal thread, pass through spiral shell when nut is threaded onto on bolt
Bolt end, which squeezes glue bead, makes its broken release fluid sealant, with the screw-in of nut make fluid sealant squeeze to entire screw-thread fit face and
Nut to realize sealed waterproof effect, while having certain retaining effect on parts contact surface.

Specific implementation mode
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below
Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
With reference to figure 1 and Fig. 2, a kind of acorn nut as shown in Figures 1 and 2, including nut 10, the nut 10 are in hexagonal
Shape, 10 one end of the nut are equipped with hemispherical end cap 11, and the nut 10 is equipped with interior spiral shell relative to one end of hemispherical end cap 11
Line 101, the internal thread 101 is interior to be equipped with glue bead 12, and the glue bead 12 is spherical in shape and boring, the glue bead 12 are equipped with note
Glue mouth 121, has fluid sealant 122 in the glue bead 12, and the gum-injecting port 121 is equipped with sealing cover 123, the gum-injecting port 121
Towards hemispherical end cap 11, coordinates fixed by transition between the glue bead 12 and internal thread 101 and be located at 101 hole of internal thread
Bottom, 101 major diameter of internal thread that the distance between the glue bead 12 and 101 aperture of internal thread are 0.5 to 1 times.
In above structure, by the way that glue bead 12 is arranged in internal thread 101, pass through bolt end when nut 10 is threaded onto on bolt
Portion, which squeezes glue bead 12, makes its broken release fluid sealant 122, matches as the screw-in of nut 10 makes fluid sealant 122 squeeze to entire screw thread
Conjunction face and nut 10 to realize sealed waterproof effect, while having certain retaining effect on parts contact surface.
