Description
Technical field
The invention belongs to fastening bolt technical fields, and in particular to a kind of Self-locking fasterning bolt.
Background technique
Bolt be two or more components or component are fastenedly connected it is integral frequently with fastener.?
When being bolted two components or component, it is necessary first to bolt be passed through mounting hole from the side to connector, act against nut
To on connector and keep bolt motionless, it is fastened on screw rod from the other side to connector using bolt nut.When wait connect
When part area is larger, people can not complete independently, need two people to complete operation in the two sides to connector respectively, make to install
Process is cumbersome, time-consuming.
Authorization Notice No. is that the Chinese utility model patent of CN207470555U discloses " self-locking fixing bolt ".The spiral shell
Bolt includes the nut that one end is equipped with externally threaded stud and is threadedly engaged with the stud, is offered in the other end of the stud
Open slot is equipped with the radial activity template for rotating shaft direction of stud in the open slot, and the activity template is turned by pin shaft
Dynamic to be connected in the open slot, described activity template one end is equipped with complementary inclined-plane, the weight of the activity template with open slot inner end
The heart is between rotation axis and the square toes of activity template.When stud penetrates bolt hole, activity template is made to be completely in the open slot
It is interior；After completion penetrates, stud is rotated 180 °, under gravity, the activity template rotation is stretched out in radial direction and is open
The activity template of slot is bonded to form block relationship with wall, and fastening nut completes the fastening of bolt.However it lives during the fastening process
Power between movable plate and stud is transmitted by rotation axis, and rotation axis is be easy to cause rotation shaft distortion or fracture, make by shearing force
Activity template is stuck or falls off.
Summary of the invention
The present invention provides a kind of Self-locking fasterning bolt, to solve in fastening bolt use process, rotation axis it is easily-deformable or
Fracture, the problem of causing loose piece stuck or fall off.To achieve the above object, the technical solution of the present invention is as follows:
