Or spray painting damages internal screw thread from nut lower end surface.
Utility model content
The purpose of this utility model is to provide a kind of elastic internal thread protection devices, to solve plastic-spraying in the prior art
Or spray painting is from nut lower end surface damage internal screw thread, the length that can not adjust long thin bar, wearability is poor and dismantles inconvenient problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of elasticity internal thread protection device, including
Guard column and protection cap, the protection outer surface of column are provided with wearing layer, and the guard column upper end is provided with protection cap, the guarantor
Guard post and protection cap are structure as a whole, and the protection cap upper surface is provided with knob, and guard circle, institute are provided on the guard column
It states guard column and is internally provided with cavity, the guard column bottom end is provided with through-hole, long thin bar is penetrated in the cavity of the guard column,
One end that the long thin bar is located at cavity inside is equipped with spacing collar, and the long thin bar other end is provided with spacing block set.
Preferably, the wearing layer is layer of polyurethane.
Preferably, the guard circle is socketed on guard column.
Preferably, the diameter of the spacing collar is slightly larger than the diameter of through-hole.
Preferably, the knob and protection cap are structure as a whole.
Compared with prior art, the utility model has the beneficial effects that the utility model is layer of polyurethane by wearing layer,
The service life that can be good at extending guard column, is socketed on guard column by guard circle, can be good at avoiding spray painting or
Person's plastic-spraying damages internal screw thread from the lower end surface of nut, and the diameter of through-hole is slightly larger than by the diameter of spacing collar, can be good at pair
Long thin bar position is adjusted, so that convenient be socketed in nut interior for guard column as needed, is by knob and protection cap
Integral structure, it is convenient that the equipment is dismantled.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the cross-sectional view of the utility model.
Fig. 3 is the structural schematic diagram of the utility model guard column and through-hole.
In figure: 1- guard column, 2- guard circle, 3- wearing layer, 4- long thin bar, 5- spacing block set, 6- knob, 7- protection cap,
8- spacing collar, 9- cavity, 10- through-hole.
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. 1~3, in the utility model embodiment, a kind of elasticity internal thread protection device, including 1 He of guard column
Protection cap 7,1 outer surface of guard column are provided with wearing layer 3, and 1 upper end of guard column is provided with protection cap 7, guard column 1 and protection cap 7
It is structure as a whole, 7 upper surface of protection cap is provided with knob 6, and guard circle 2 is provided on guard column 1, and guard column 1 is internally provided with
Cavity 9,1 bottom end of guard column are provided with through-hole 10, and long thin bar 4 is penetrated in the cavity 9 of guard column 1, and long thin bar 4 is located in cavity 9
The one end in portion is equipped with spacing collar 8, and long 4 other end of thin bar is provided with spacing block set 5, and guard column 1 and protection cap 7 are silica gel material
It is made, long thin bar 4 is made of rigid plastics, pulls long thin bar 4 according to the depth of nut, holds long thin bar 4 to facilitate, will grow
Thin bar 4 penetrates nut, and then long 4 one end of thin bar is pierced by nut, pulls long thin bar 4, and guard column 1 is socketed in spiral shell to facilitate
Female internal, then the upper surface of protection cap 7 and nut is adapted, and adjusts the position of spacing collar 8, is close to spacing collar 8 under nut
End face, so that spray painting or plastic-spraying be avoided to damage internal screw thread from the lower end surface of nut well, wearing layer 3 can be good at extending
The service life of guard column 1, wearing layer 3 are layer of polyurethane, and guard circle 2 is socketed on guard column 1, and the diameter of spacing collar 8 is bigger
