The advantages that facilitating.Threaded connection typically has self-locking performance, and the frictional force on the supporting surface of nut and bolt head also has locking in addition
Effect, thus nut tighten it is latter as will not release.In real work, under shock and vibration or varying load effect, and in high temperature
Or temperature change it is larger when, normal pressure is in a certain pop-off, frictional force zero in screw thread pair so that threaded connection loosens,
Such as through repeated action, threaded connection will be loose and fail, have impact on the normal operation of equipment, it is necessary to usually repeat locking behaviour
Make, so as to add labor intensity, and certain potential safety hazard be present.
Utility model content
The utility model is in order to solve the above problems, there is provided a kind of reasonable in design, convenience quick for installation, stability
It is good, effectively can reduce or avoid in use fastener there is the check bolt of loose or dislocation phenomenon.
The utility model adopts the following technical scheme that：
A kind of check bolt, including bolt body, the bolt body include screw rod and are arranged at the screw rod of screw rod one end
Head, the outer surface of the screw rod are provided with external screw thread, and corresponding to externally threaded opening position on the screw rod is provided with through screw rod
Groove, for the groove along the length direction setting perpendicular to screw rod, the groove is interior to be provided with two cunnings being symmetrically set
Block, is provided with spring between described two sliding blocks, and the first inclined-plane, the screw head are provided with close to one end of screw head on the sliding block
On be provided with along the axis direction of screw rod and what groove communicated pushes away groove, it is described to push away that be provided with groove be along pushing away pushing away for groove slip
Block, is provided with the second inclined-plane mutually agreed with the first inclined-plane on the pushing block close to one end of sliding block, the other end of the pushing block with
Push away and be provided with clamping mechanism between groove.
As a kind of optimal technical scheme of the present utility model, the clamping mechanism, which includes being arranged at, to be pushed away in groove close to screw rod
The catch at first end and the locating piece for being arranged at close screw head one end on the outer wall of pushing block, the catch is provided with and locating piece
Corresponding locating slot, the locating piece can block and in locating slots.
As a kind of optimal technical scheme of the present utility model, one end away from sliding block is provided with and is easy to push away on the pushing block
The cross recess of block rotational positioning.
The beneficial effects of the utility model are：
1st, the utility model is reasonable in design, can be outside using the setting of externally threaded opening position is corresponded on screw rod
The sliding block of slip, sliding block is connected in nut after screw bolt and nut connects, loosened so as to effectively avoid threaded connection
Phenomenon；
2nd, it is of the present utility model in pushing block and to push away the stabilization that the clamping mechanism set between groove can effectively ensure that pushing block
Property, so as to strengthen bolted stability, meanwhile, the cross recess set on pushing block so that the slip and clamping of pushing block are more
The convenience added, enhance the using effect of bolt.
