Abstract
The utility model discloses a kind of bolt protective lids of metal material, it is sealed including top, the hollow lid of bottom opening, the hollow lid is integrally formed by metal material, the top of the hollow lid is bolt receiving portion, lower part is nut accommodating portion, the inner wall of the bolt receiving portion and nut accommodating portion is cylinder, and the internal diameter of bolt receiving portion matches with the diameter of bolt, there is internal thread on the inner wall of bolt receiving portion, the screw thread of the internal thread and bolt head cooperates, the internal diameter of nut accommodating portion matches with nut outer diameter, the height of nut accommodating portion and the height of nut match.The bolt protective lid of the utility model uses metal cap body, not only waterproof antirust, but also UV resistant irradiation, and there is high intensity, it will not crack because of the expansion of bolt and nut, and be tightly combined with bolt, be not easy to loosen, it can also be stuck in nut top surface, prevent nut from loosening.
Description
Technical field
The utility model is related to a kind of bolt protective lids of metal material, belong to fastener protection field.
Background technology
Bolt as a kind of most commonly seen fastener being detachably connected, be widely used in electronic product, digital product,
The fields such as mechanical equipment, ship, vehicle, bridge, road, municipal administration, hydraulic engineering, wherein be used in mechanical equipment, ship, vehicle,
Bolt in the large products such as bridge, road, municipal administration, hydraulic engineering is often exposed to vibration, friction, humidity, exposes to the weather
In environment, bolt is easy to loosen, corrosion, needs periodic inspection, gently then influences working efficiency, heavy then bring security risk, therefore,
The anti-corrosion of bolt, locking protection work are particularly important.
Generally the leakage part of screw bolt and nut is covered using bolt protective cover in the prior art, to protect it from by
Corrosion, however existing bolt protective cover is made of plastic material mostly, although certain waterproof, anti-rust action can be played,
But intensity difference is easy aging, especially in the summer of high temperature, bolt of the different plastic safety cover of the coefficient of expansion in metal material
Expansion with unable to bear in the state of nut expanded by heating bolt and nut and crack.In addition, existing bolt protective cover
All it is to be covered on bolt by way of clamping, it is vibrated to be easy to fall off in conjunction with defective tightness.
Utility model content
The purpose of the utility model is to overcome deficiencies in the prior art, provide a kind of not only waterproof antirust, but also with height
Intensity, and with the compact bolt protective lid of bolt.
To achieve the above object, the technical solution that the utility model is taken is as follows：
A kind of bolt protective lid of metal material includes the hollow lid of top sealing, bottom opening, the hollow lid
It is integrally formed by metal material, the top of the hollow lid is bolt receiving portion, lower part is nut accommodating portion, and the bolt holds
The inner wall of portion and nut accommodating portion received is cylinder, and the internal diameter of bolt receiving portion matches with the diameter of bolt, and bolt holds
Receiving has internal thread on the inner wall in portion, and the screw thread of the internal thread and bolt head cooperates, the internal diameter of nut accommodating portion with
Nut outer diameter matches, and the height of nut accommodating portion and the height of nut match.
As further preferred, the metal material is aluminium or titanium, and aluminium and titanium itself are not easy to get rusty, and protection effect is more
It is good.
As further preferred, the hollow lid is by metal material integrally casting shaping.
As further preferred, anodized is passed through in the outer surface of the hollow lid, not only beautiful but also anti-corrosion, also
It is resistant to 400 DEG C or more of high temperature.
As further preferred, there is non-slip texture, further functioning as prevents nut on the inner wall of the nut accommodating portion
The effect loosened.
The beneficial effects of the utility model are as follows：
（1）The bolt protective lid of the utility model uses metal cap body, not only waterproof antirust, but also UV resistant irradiation, and
And there is high intensity, it will not crack because of the expansion of bolt and nut.
（2）The bolt protective lid of the utility model has on the inner wall of bolt receiving portion mutual with the screw thread of bolt head
The internal thread of cooperation, the mode that can be connected through a screw thread are assembled on bolt, are tightly combined, are not easy to loosen.
（3）The bolt protective lid of the utility model, the height of nut accommodating portion and the height of nut match so that nut
The inner wall top surface of receiving portion can be stuck in nut top surface, play the role of preventing nut from loosening.
Description of the drawings：
Fig. 1：The stereogram of the bolt protective lid of the utility model；
Fig. 2：The bolt protective lid of the utility model is assemblied in the schematic cross-sectional view on bolt.
Specific implementation mode：
The utility model is described further in the following with reference to the drawings and specific embodiments.
As illustrated in fig. 1 and 2, the bolt protective lid of the metal material of the utility model, including top sealing, bottom opening
Hollow lid, the hollow lid are integrally formed by metal material, and the top of the hollow lid is bolt receiving portion 1, lower part
For nut accommodating portion 2, the inner wall of the bolt receiving portion 1 and nut accommodating portion 2 is cylinder, and bolt receiving portion 1
The diameter of internal diameter and bolt 3 matches, and has internal thread, the internal thread and 1 head of bolt on the inner wall of bolt receiving portion 1
Screw thread cooperates, and thread connecting mode is tightly combined, is not easy to loosen, the internal diameter of nut accommodating portion 2 and the outer diameter phase of nut 4
Match, the height and the height of nut 4 of nut accommodating portion 2 match so that the inner wall top surface of nut accommodating portion 2 can be stuck in nut
4 top surface plays the role of preventing nut 4 from loosening, and the metal material is aluminium or titanium, and the hollow lid is by metal material one
Anodized is passed through in the outer surface of body casting and forming, the hollow lid, not only beautiful but also anti-corrosion, moreover it is possible to resistance to 400 DEG C or more
High temperature, there is on the inner wall of the nut accommodating portion 2 non-slip texture.
Only the utility model and embodiments thereof are described above, description is not limiting, shown in attached drawing
Also be the utility model one of embodiment, actual structure is not limited to this, if those skilled in the art by
It is enlightened, and without deviating from the purpose of the present invention, is designed and the technical solution phase without creative
As structure and embodiments thereof, the scope of protection of the utility model should all be belonged to.
