Description
Technical field
The present invention relates to a kind of check bolt, belongs to a kind of fastener.
Background technology
Fastener is most widely used fundamental parts, is to be fastenedly connected into two or more parts or component
The general name of used a kind of machine components during one entirety.Fastener description is various, performance purposes each one, and standard
It is change, seriation, unitized strong.Wherein bolt is most common one kind in fastener.Conventional bolt generally comprises
Head and the screw rod being connected under head, the bolt of this structure, simple in construction, performance is also general, right at some
Using effect requires higher occasion, and traditional bolt can not meet use demand.Therefore, it should provide a kind of new
Technical scheme solves the above problems.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, bolt of the good improved structure of using effect.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of check bolt of special improved structure, including bolt head and screw rod, the lower surface connection of the bolt head
Screw rod, another end face are provided with central recess, and bolt head is circumferentially distributed several recesses, and the front end of the screw rod is screw thread
Section, one end close to bolt head is smooth section, hairbrush circle is equipped with the thread of the screw rod end, the smooth section tightens
It is close to be connected with mould set shell.
Further technical scheme：
The diameter of the mould set shell is less than the diameter of thread segment.
The bolt head and the edge of the lower surface of screw rod junction are provided with annular sealing strip.
The bolt head is circular bolt head.
The mould set shell is closely connected by way of fixture block and neck are engaged with smooth section.
Due to the application of above-mentioned technical proposal, the present invention has the following advantages that compared with prior art：
1st, bolt of the invention, due to being equipped with hairbrush circle on the thread of screw rod end, in bolt precession screw,
Hairbrush circle contacts with the internal thread of screw first, and hairbrush encloses the effect of the impurity on the internal thread in cleaning screwed hole.
2nd, bolt of the invention, due to being provided with mould set shell in smooth section, during the humidity of bolt installation place, mould set shell and bolt
Bar is completely embedded, and not tending to have steam and entering causes shank of bolt to get rusty, shank of bolt will not corrosion in mounting hole, it is convenient during dismounting.
3rd, bolt of the invention, bolt head and the edge of the lower surface of screw rod junction are provided with bolt described in annular sealing strip
The edge of the lower surface of head is provided with annular sealing strip, can ensure sealing without separately be added gasket during use.
Brief description of the drawings
Accompanying drawing 1 is schematic structural view of the invention.
Accompanying drawing 2 is bolt head inside structure schematic diagram.
In the figures above：1st, bolt head, 2, screw rod, 3, recess, 4, hairbrush circle, 5, mould set shell, 6, sealing strip.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment one：
As shown in figure 1, a kind of check bolt of special improved structure of the present invention, including bolt head 1 and screw rod 2, it is described
The lower surface connecting screw 2 of bolt head 1, another end face are provided with central recess 3, and bolt head 1 is circumferentially distributed to have several recessed
Mouth 3, the front end of the screw rod 2 is thread segment, and one end close to bolt head 1 is smooth section, on the thread of the end of screw rod 2
Hairbrush circle 4 is equipped with, mould set shell 5 is closely connected with the smooth section.
Preferably, second embodiment as the present invention, the present embodiment are the further restrictions to embodiment one, mould set
Shell 5 is closely connected by way of fixture block and neck are engaged with smooth section.
Preferably, the 3rd embodiment as the present invention, the present embodiment are also the further restriction to embodiment one, institute
The diameter for stating mould set shell 5 is less than the diameter of thread segment.
Preferably, the 4th embodiment as the present invention, the present embodiment are the further improvement to embodiment one, bolt
The edge of first 1 lower surface being connected with screw rod 2 is provided with annular sealing strip 6.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvement or replacement can also be made, these improve or replaced
It should be regarded as protection scope of the present invention.
