Abstract
The invention relates to an anti-loosening device for a fastening piece, in particular to an anti-loosening device for a socket head cap screw. The anti-loosening device is structurally characterized by comprising a bridge frame, an external angle bolt group and an external angle anti-loosening mechanism used on the external angle bolt group. An external angle bolt head corresponds to a hexagon socket head of the socket head cap screw and is clamped in a hexagon socket groove of the socket head cap screw head. A suspension extending end of the bridge frame is fastened between a bolt head and a nut of the external angle bolt group, the external angle anti-loosening mechanism works between the external angle bolt group and the bridge frame, and a bridge frame main body is fixedly connected with an outer frame. The anti-loosening device is applicable to severe working conditions such as heavy load, variable load, impacting and large vibration and can effectively prevent loosening.
Description
Technical field
The present invention relates to a kind of fastener locking device, especially a kind of locking device of socket head screw, it is fit to be applied in and is subjected to heavy duty, varying load, temperature variation large, and shock and vibration is large, and under the operating mode such as rugged environment.
Background technique
Common in nut anti-looseness device or the anti-loosening device of bolt prior art, this locking device arranges for exterior angle (outer-hexagonal or outer four jiaos etc.) nut.Under tight space, generally can select socket head screw.Existing Large-Scale Equipment is large in heavy duty, varying load, temperature variation, shock and vibration is large, and sometimes also can't select outer corner bolt under the operating mode such as rugged environment, and must select socket head screw, so the locking locking of socket head screw proposed requirement, and existing nut anti-looseness device can't be applied on the socket head screw directly.
Summary of the invention
The object of the invention is to overcome deficiency of the prior art, a kind of to be suitable for being applied in heavy duty, varying load, shock and vibration large etc. than under the bad working environments and provide, socket head screw locking device that can be effectively locking.
The objective of the invention is to realize by following approach.
A kind of locking device of socket head screw, it forms main points and is: comprise bridge joint frame, a kind of outer corner bolt group and be applied in exterior angle locking gear on this outer corner bolt group, corresponding and the jam of the hexagon socket head of exterior angle bolt head and socket head screw is in the interior hex slot of this socket head screw head, bridge joint frame one overhangs between the distolateral bolt head and nut that is fastened on outer corner bolt group, the exterior angle locking gear acts between outer corner bolt group and the bridge joint frame, and this bridge joint frame body and outer frame are affixed.
Above-mentioned outer frame refers to by the object of the fastening locking of socket head screw or the object affixed with this object.
The bolt head of outer corner bolt group is that outer-hexagonal is corresponding with the socket head screw head, this correspondence be form responding also be that big or small correspondence can form and cooperate to connect, and by this outer corner bolt group and bridge joint frame hexagon socket head is converted to outer angle head, making locking being converted to of socket head screw is the locking of outer corner bolt or nut, like this, of the prior art all for the equal choice and application in addition of the locking device of outer corner bolt group or nut, not only be suitable for being applied in heavy duty, varying load, impact, vibration is large to be waited than under the bad working environments, but also have a unexpected effect, be: exploitativeness is good.
Purpose of the present invention can also realize by following approach.
The bridge joint frame is fastenedly connected by a kind of bolt and outer frame.
This bridge joint frame bolt is a kind of outer corner bolt with locking device.
The bridge joint frame is a kind of T shape, and its T shape both end sides is respectively by one group of outer corner bolt group and two corresponding being fastenedly connected of socket head screw.
Such bridge joint frame is finished the locking of two socket head screws simultaneously, and not only structure is more simple, and two socket head screws are bridged frame and are tightened to one, mutually pins down, and the locking anti-loosing effect is better.
Can select wherein a kind of of Tang Shi threaded connection pair, Spiralock nut, nut and locked spacer combination with the nut of the outer corner bolt group of locking gear.
As preferably.Can adopt the combination of lock washer with tongue at outside and nut.
In sum, the present invention has following advantage compared to existing technology: utilize corner bolt outside the interior hex slot of socket head screw head is installed, making locking being converted to of socket head screw is the locking of outer corner bolt or nut, like this, of the prior art all for the equal choice and application in addition of the locking device of outer corner bolt group or nut, it is large etc. than under the bad working environments not only to be suitable for being applied in heavy duty, varying load, shock and vibration, large-scale being threaded of using is particularly useful for the locking of hydraulic pressure liquid-filling valve.Owing to be just to use existing nut anti-looseness device by the structure conversion, so exploitativeness is good.
