Description
Technical field
The present invention relates to a kind of special check bolt, belong 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, anti-loosing effect is bad, when bolt uses
Very big occasion is being vibrated, security just cannot be guaranteed.Therefore, it should a kind of new technical scheme is provided and solves above-mentioned ask
Topic.
The content of the invention
It is an object of the invention to provide a kind of simple in construction, good check bolt of using effect.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of special check bolt, including bolt head and screw rod, the screw rod include threaded portion and unthreaded sections,
Unthreaded sections in screw rod and the position close to bolt head, at least three fins are provided with along the circumferencial direction of screw rod, should
Check bolt also includes a cannulated sleeve, and the cannulated sleeve is provided with the groove being engaged with fin, institute along its circumferencial direction
The unthreaded sections that cannulated sleeve is set in screw rod are stated, and fin is embedded into groove, the rear end of the screw flight part
Extension is provided with, through hole is provided with the extension, is also associated with covering on one on the bolt head, the upper lid and bolt head
It is adapted, upper lid is fastened on bolt head, and is hinged between upper lid and bolt head.
Further technical scheme：
Fastening cap is additionally provided with screw rod below the bolt head, the fastening cap is welded and fixed with screw rod, the fastening
Cap is taper, and is stretched out to screw rod outside.
The lower end of the fastening cap is provided with wave linear shape anti-slop serrations.
Due to the application of above-mentioned technical proposal, the present invention has the following advantages that compared with prior art：
1st, after the threaded portion of check bolt of the invention screws in screwed hole, the fin on screw rod outside screwed hole, and with
Workpiece surface contact, cannulated sleeve is inserted in non-threaded section of screw rod from the end of screw rod, by the groove on cannulated sleeve with it is convex
Rib coordinates, then cannulated sleeve is fixed in connection surface with holding screw can complete the locking of bolt.Due to after screw rod
End is provided with extension, is provided with through hole on extension, the rear end of screw rod can be positioned through through hole by determining holding screw, locking
Effect is more preferable.
2nd, check bolt of the invention, is connected with one on bolt head and covers, and covers upper lid after bolt is installed into fixed
Close, it can protect bolt head, avoid its corrosion, when disassembly is desired, as long as being covered on opening.
Brief description of the drawings
Accompanying drawing 1 is schematic structural view of the invention.
Accompanying drawing 2 is the bolt arrangement schematic diagram with upper lid.
Accompanying drawing 3 is cannulated sleeve top view.
In the figures above：1st, bolt head, 2, screw rod, 3, fin, 4, groove, 5, extension, 6, through hole, 7, upper lid, 8, tight
Gu cap, 9, anti-slop serrations, 10, cannulated sleeve.
Embodiment
Below in conjunction with the accompanying drawings and embodiment the invention will be further described：
Embodiment one：
As Figure 1-3, a kind of special check bolt of the present invention, including bolt head 1 and screw rod 2, the screw rod 2 include
Threaded portion and unthreaded sections, the unthreaded sections in screw rod 2 and the position close to bolt head 1, along the circumference side of screw rod 2
To being provided with least three fins 3, the check bolt also includes a cannulated sleeve 10, and the cannulated sleeve 10 is along its circumferencial direction
The groove 4 being engaged with fin 3 is provided with, the cannulated sleeve 10 is set in the unthreaded sections of screw rod 2, and fin 3 is embedded in
Into groove 4, the rear end of the threaded portion of the screw rod 2 is provided with extension 5, and through hole 6 is provided with the extension 5, described
Lid 7 on one are also associated with bolt head 1, the upper lid 7 is adapted with bolt head 1, and upper lid 7 is fastened on bolt head 1, and upper lid
It is hinged between 7 and bolt head 1.
Preferably, second embodiment as the present invention, the present embodiment is the further restriction to embodiment one, described
Fastening cap 8 is additionally provided with the screw rod 2 of the lower section of bolt head 1, the fastening cap 8 is welded and fixed with screw rod 2, and the fastening cap 8 is cone
Shape, and stretched out to the outside of screw rod 2, fastening, 8 lower end is provided with wave linear shape anti-slop serrations 9.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
