Description
Technical field
The invention belongs to shockproof follower link field, more particularly, to a kind of hinged bolt nut against shock knot
Structure.
Background technology
In modern industry, bolt and nut is common connector.Common standard bolt nut structure is simple, user
It just, but cannot effective locking against shock.High-speed rotating axis class, for a long time by vibrations force effect spare and accessory parts etc., to bolt
The vibration resistance of connection has higher requirement, to meet connection request, needs to design with against shock, the screw thread to fall off company
It connects.The locking dismounting of the machinery such as split pin, stop washer of generally use is inconvenient, rushes the rivetings such as point, welding and rushes and locking is broken when dismantling
Bad shank of bolt causes shank of bolt can not secondary use.While designing bolt and nut shockproof structure, structure is also considered
Detachability.
Invention content
In view of this, the invention is directed to a kind of hinged bolt nut shockproof structure.
In order to achieve the above objectives, the technical solution of the invention is realized in：
A kind of hinged bolt nut shockproof structure includes bolt, nut, against shock rubber block, elastic anchor ear, nut
Top circumferential wall is uniformly arranged that there are three straight slots for installing against shock rubber block, outer circle wall setting below the straight slot of nut top
Boss, elastic anchor ear inner wall are contacted with the extruding of against shock rubber block outer wall, and elastic anchor ear bottom surface is contacted with boss upper surface.
Against shock rubber block thickness is less than straight slot 0.5mm to the 1mm of nut top circumferential wall setting；In against shock rubber block
Side is provided with screw thread and coordinates with bolt；When against shock rubber block inside thread and bolt thread contact, nut is protruded in outside
Top periphery；Boss is respectively set in elastic anchor ear setting opening, opening both sides, is respectively set that there are one logical on boss side plane
Hole coordinates with Circlip tongs；Nut top periphery is provided with skid resistant course.
In use, filling in three pieces of against shock rubber blocks respectively in three straight slots of nut first, against shock rubber is paid attention to
Block screw thread is consistent with nut inner thread direction；Bolt and nut is respectively put into from the part two sides to be clamped respectively, tightens bolt
Nut；Elastic anchor ear boss hole is passed through using Circlip tongs binding clip, elastic anchor ear is opened into rear enclosure outside against shock rubber block, is taken
Lower circlip clamps, and so that the tight inside of elastic anchor ear is pressed on the outside of against shock rubber block, ensures against shock rubber block inside thread and spiral shell
Bolt screw thread squeezes contact, prevents bolt and nut from falling off loosening using frictional force.
High-speed rotating axis class, for a long time by vibrations force effect spare and accessory parts etc., to bolted vibration resistance have compared with
High requirement needs to design with against shock, the threaded connection to fall off to meet connection request.The split pin of generally use,
The locking dismounting of the machinery such as stop washer is inconvenient, rush the rivetings such as point, welding rush it is locking destroy shank of bolt when dismantling, cause shank of bolt without
Method secondary use.While designing bolt and nut shockproof structure, the detachability of structure is also considered.
Compared with the existing technology, a kind of hinged bolt nut shockproof structure described in the invention, it is easy to disassemble,
Disassembly process does not destroy bolt-nut connecting structure, ensures the secondary use of bolt and nut, spiral shell can be effectively prevent using frictional force
The vibrations of bolt nut fall off.
