Description
Technical field
The present invention relates to bolt assembly technical field, specially a kind of bolts convenient for locking and can be locking.
Background technology
Bolt is conventional type fastener relatively conventional in daily life, and the zero of through-hole is carried for being fastenedly connected two
Part, when use, need to coordinate with nut, and screw rod is inserted into hole in piece part, external force application means such as spanner etc. is reused and revolves nut
Tightly, though such bolt fastening is more common, consider that part has a demand property of dismounting, mistake when tightening nut or bolt
Big torque is unfavorable for the facility of dismounting, and simple thread locking structure has its limitation, under larger dynamic loading its
Self-locking reliability can reduce.
Invention content
(1) technical problems to be solved
The present invention provides a kind of bolt convenient for locking and can be locking, dismounting and locking problem primarily directed to bolt；
Using technical solution provided by the present invention, the fast assembling-disassembling of bolt can be not only realized, but also can after bolt screws
It effectively prevent its loosening.
(2) technical solution
To achieve the above object, the present invention provides following technical solution：A kind of bolt convenient for locking and can be locking, including
Camlock spanner, screw rod, nut, the camlock spanner are hinged on the non-threaded end of the screw rod, the nut installation
At the screw flight end；The screw rod includes the first screw rod, the second screw rod, inner screw, and the camlock spanner is hinged
In one end of first screw rod, the nut is mounted on second screw rod；The center of first screw rod is along axis side
It is equipped with perforative second connecting hole in the axial direction to the center equipped with perforative first connecting hole, second screw rod, it is described
Inner screw passes through second connecting hole to be mounted in first connecting hole；The second screw flight section upper edge axis side
To equipped with rotation stop grooving, the head of the inner screw is equipped with the rotation stop convex body coordinated with the rotation stop grooving；The inner screw
Head is back taper structure.
Through the above technical solutions, when this is used to be bolted part, camlock spanner is gone to put first
The state of pine suitably tightens bolt on screw rod and then rotates clockwise drive the first screw rod rotation of camlock spanner, due to
It is threadedly coupled between inner screw and the first connecting hole, and the rotation stop convex body on inner screw head is mounted on the rotation stop grooving of the second screw rod
In, therefore the first screw rod is rotated relative to inner screw, inner screw precession into the first connecting hole, turns not moving cam when clockwise manually
When locking wrench, pull camlock spanner certain angle and connect fastening parts, at the same time inner screw head fall
Wimble structure, which enters in the second connecting hole, to be strutted the thread segment of the second threaded rod, and then can be effectively prevented the loosening of nut.
When dismantling the bolt, pulling camlock spanner first loosens entire bolt, then rotates counterclockwise convex
Wheel locking wrench makes inner screw be screwed out out of first connecting hole, so that the back taper structure on inner screw head exits the second connection
Hole, convenient for users to nut is disassembled from the second screw flight section.
In further technical solution, be socketed with screw jacket on the screw rod, on first screw rod its with it is described
Rotating cylinder is installed between screw jacket；The side of the screw jacket is equipped with rectangular hangnail outlet slot, and the hangnail
The length direction of outlet slot is consistent with the axis direction of the screw jacket, the opposite side in two positions of the hangnail outlet slot
Face is equipped with slot, and the spring leaf of strip is equipped in the slot, hangnail group, the rotating cylinder are equipped on the spring leaf
Side be equipped with the protrusion of conjunction assembled with the hangnail.
In Pass through above-mentioned technical proposal, when this is used to be bolted part, rotation cam locking wrench drives the
One screw rod rotates, and for the rotating cylinder on the first screw rod also with rotation, the hangnail group on protrusions press spring leaf on rotating cylinder side will
It is released from hangnail outlet slot, is contacted with the connecting hole inner wall on part, is further improved bolted reliability；When tearing open
It is rotated further camlock spanner when unloading bolt, the protrusion on rotating cylinder side is detached with hangnail group, and hangnail group is in spring leaf
Under the action of reset, so as to facilitate realize bolt dismounting.
In further technical solution, convex body A is equipped on the side of first screw rod in the axial direction, the rotating cylinder
Inner surface is equipped with the sliding slot coordinated with the convex body A；The setting can effectively ensure that rotation by the cooperation of convex body A and sliding slot
Drum rotation is driven while first screw rod.
In further technical solution, the hangnail group includes the hangnail body of strip, and the hangnail body is equipped with and institute
The hangnail of hangnail outlet slot cooperation is stated, the hangnail body is equipped with the spliced eye coordinated with the spring leaf；The setting is by falling
Hangnail body can be mounted on spring leaf by the cooperation of spliced eye and spring leaf on nematophore.
In further technical solution, ring-shaped rubber is being installed with the camlock spanner connecting pin on the screw rod
Pad；Setting ring-shaped rubber pad facilitates the locking of camlock spanner first, next plays anti-skidding effect, prevents camlock from pulling
Hand loosens.
In further technical solution, metal gasket is being installed with the nut connecting pin on the screw rod.
(3) advantageous effect
Compared with prior art, technical scheme of the present invention has the following advantages：The screw rod is divided into the first screw rod,
Two screw rods, inner screw, and realize by the cooperation of the first screw rod, the second screw rod, inner screw the fast assembling-disassembling of bolt, and in spiral shell
Bolt can effectively prevent its loosening after screwing；Telescopic hangnail device is set outside screw rod, by controlling stretching for hangnail
Bolted reliability can further be realized by going out.
