Technical Field
The utility model relates to a protection device of fastening member especially relates to a bolt protective cap.
Background
Although the bolt is a common fastening component, the parts connected by the bolt can achieve the purpose of fastening, the connected nut and the screw rod protruding out of the nut are exposed to the atmosphere, so that the threads on the threaded connection part and the protruding screw rod are polluted by rainwater and dust, and are easily corroded in the atmospheric environment; the corroded bolt is difficult to loosen, and inconvenience is brought to replacement of parts.
Therefore, the prior art provides a bolt protection cap, which is a hollow cap structure, the inner wall surface of which is provided with a clamping convex point, when in use, the cap is clamped on the outer side of the nut, and the cap is fixed on the nut by the friction force of the convex point and the slight elasticity of the cap. However, since the protective cap is fixed to the nut only by friction or elastic force, the protective cap is not firmly fixed and can be easily detached from the nut by a small external force. In particular, wind power generation equipment is often installed in wide areas where wind resources are abundant, such as: grassland, desert edge etc. place, these places have livestock such as ox, horse, sheep of crowd, the current bolt protective cap of installation on the wind power generation equipment is very easily passed through the rubbing of health and is dropped by these livestock, causes certain economic loss and equipment operation hidden danger. On the other hand, the wind and sand in grassland, desert and other places are large, the ultraviolet intensity is also large, the existing bolt protective cap does not have the functions of weathering resistance and ultraviolet resistance, the service life is short, and the bolt protective cap needs to be replaced frequently.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a bolt protective cap which can be firmly connected to a nut and a screw rod protruding out of the nut, and can effectively protect exposed threads; meanwhile, the bolt protective cap can resist weathering and ultraviolet rays, and the service life can be prolonged, so that the use cost is reduced.
The utility model aims at realizing the protection cap of the bolt, which is a hollow step-shaped shell with a small top and a big bottom, and comprises a lower shell covering the nut and an upper shell connected with the head of the bolt; the inner parts of the upper shell and the lower shell are through stepped round holes; the aperture of the lower shell is larger than or equal to the maximum outer diameter of the nut; the upper shell is provided with an internal thread which can be screwed with the bolt; the outer part of the upper shell is prism-shaped; the upper shell and the lower shell are integrally formed by ultraviolet-resistant and weathering-resistant plastics.
In a preferred embodiment of the present invention, the anti-ultraviolet and anti-weathering plastic is formed by mixing linear low density polyethylene, high density polyethylene and ultraviolet absorber.
In a preferred embodiment of the present invention, the ultraviolet absorber is an ultraviolet resistant complexing agent.
In a preferred embodiment of the present invention, the outer portion of the upper housing is a triangular prism, a quadrangular prism, a pentagonal prism, a hexagonal prism, or an octagonal prism.
In a preferred embodiment of the present invention, the height of the lower housing is greater than or equal to the thickness of the nut.
From the above, the bolt protective cap of the present invention has internal threads inside, and the outer part of the upper shell is prismatic, so that the bolt protective cap can be screwed on the head of the bolt directly by hand or by using a wrench, so that the lower shell covers the nut to protect the exposed threads; because the bolt protective cap is screwed on the bolt, the bolt protective cap can be firmly fixed on the bolt and cannot fall off under the action of external force such as strong wind or scratching of cattle and sheep, so that the economic loss can be reduced, and the hidden danger of operation of related equipment can be avoided. Meanwhile, the bolt protective cap is made of ultraviolet-resistant and weather-resistant plastics, so that the bolt protective cap can resist the invasion of ultraviolet rays and wind sand, the service life can be prolonged, and the use cost can be reduced.

Detailed Description
In order to clearly understand the technical features, objects, and effects of the present invention, embodiments of the present invention will be described with reference to the accompanying drawings.
As shown in fig. 1 to 4, the bolt protection cap 1 of the present invention is a hollow stepped housing with a small top and a large bottom, and is composed of a lower housing 12 covering the nut 3 and an upper housing 11 connected to the head of the bolt 2; the upper shell 11 and the lower shell 12 are internally provided with through stepped round holes (as shown in fig. 3); the aperture of the lower shell 12 is larger than or equal to the maximum outer diameter of the nut 3, so that the lower shell 12 can be smoothly covered on the nut 3; the upper shell 11 is provided with an internal thread 111, the internal thread 111 has the same parameters as the external thread on the bolt 2, and the bolt protective cap 1 can be screwed on the head of the bolt 2 through the internal thread (namely, the bolt protrudes out of a partial screw rod of the nut 3); in the present embodiment, as shown in fig. 1 and 2, the outer portion of the upper case 11 is prism-shaped; the upper shell 11 and the lower shell 12 are made of ultraviolet-resistant and weathering-resistant plastics by integral molding.
As described above, the bolt protection cap 1 of the present invention has internal threads inside, and the upper shell 11 is prism-shaped outside, so that the bolt protection cap 1 can be directly screwed on the head of the bolt 2 by hand or using a wrench, and the lower shell 12 covers the nut 3 to protect the exposed threads; because the bolt protective cap 1 is screwed on the bolt, the bolt protective cap 1 can be firmly fixed on the bolt and cannot fall off under the action of external force such as strong wind or scratching of cattle and sheep, so that the economic loss can be reduced, and the hidden danger of operation of related equipment can be avoided. Meanwhile, the bolt protective cap 1 is made of ultraviolet-resistant and weather-resistant plastics, so that the bolt protective cap can resist the invasion of ultraviolet rays and wind sand, the service life can be prolonged, and the use cost can be reduced.
Further, in the present embodiment, the ultraviolet and weathering resistant plastic is formed by mixing linear low density polyethylene (LLPE), High Density Polyethylene (HDPE), and an ultraviolet absorber, and the ultraviolet absorber is an ultraviolet resistant composite agent.
As shown in fig. 1 and 2, in the present embodiment, the outer portion of the upper case 11 has an octagonal prism shape to facilitate screwing the bolt protection cap 1 to the bolt 2 using a wrench, but the outer portion of the upper case 11 may have a quadrangular prism or a hexagonal prism; the outer portion of the upper case 11 may have a triangular prism shape, a quadrangular prism shape, or the like without using a wrench, as long as it can be directly screwed by hand.
Further, as shown in fig. 4, in the present embodiment, the height of the lower case 12 is equal to or greater than the thickness of the nut 3 so that the lower case 12 can completely cover the nut 3.
The above description is only exemplary of the present invention, and is not intended to limit the scope of the present invention. Any person skilled in the art should also realize that such equivalent changes and modifications can be made without departing from the spirit and principles of the present invention.
