Description
Technical field
The utility model is related to railway machinery fields more particularly to a kind of bolt looseness to inhibit structure.
Background technology
Current locking locking plate is a rectangle steel plate, and length is more than braking rail and caliper in braking rail (pincers)
The maximum width of the bolt head (hexagonal) for two pitchs of bolts tightened up+tightened up, width are more than fixing bolt
The maximum width of head (hexagonal)；
The turret head of two fastening bolts is washed out according to the pitch-row in braking rail (pincers) on locking plate, is fastened in two bolts
Afterwards, locking locking plate is sleeved on two bolt heads, plays the purpose for preventing bolt rotation (loosening).
It has the following disadvantages：
1. being frequently not the relative position of the bolt head on locking plate after bolt fastening, need to one angle of back rotation,
Locking plate can be put on；
2. after set upper collet, to prevent locking plate from scurrying out, needing to be inserted into a split pin in such as figure position；Fastening braking rail,
The bolt of caliper is substantially about needed to unclamp, adjustment, be tightened up again every two weeks because of jaw size to be adjusted.Due to opening
It sells yielding, is difficult to dismantle, and split pin will be fractureed with 3-4 times after deformation, scene is difficult to use.
Utility model content
The utility model is mainly solving the technical problems that provide a kind of bolt looseness inhibition structure, in adjustment jaw size
After bolt fastening, it may be convenient to locking locking plate is sleeved on two bolt heads, play locking effect, while will using clamp spring
Locking locking plate is fixed on bolt head, easy disassembly.
In order to solve the above technical problems, the technical solution that the utility model uses is：A kind of bolt looseness suppression is provided
Structure processed, including special shaped screw bolt, special-shaped locking plate, clamp spring and abnormity nut in braking rail are configured, the abnormity locking plate is set
It is equipped with the regular polygon lockhole to match with the special shaped screw bolt, special shaped screw bolt, the special shaped screw bolt packet are penetrated in the lockhole
The bolt stem to match containing the bolt head to match with lockhole and with braking rail, the bolt head loins level offer clamp spring
Slot, is arranged a through-hole in the jump-ring slot, and the bolt head loins level height is higher than special-shaped locking plate thickness, in the jump-ring slot
It is provided with clamp spring, the clamp spring has loosening that gap, the bolt stem is inhibited to be pierced by from braking rail bottom with special-shaped locking plate retention, institute
Abnormity nut is stated by bolt stem screw threads for fastening in braking rail bottom surface.
In one preferred embodiment of the utility model, the abnormity nut is integrally formed, including barrel nut ontology
And rectangle tabletting, the barrel nut inner body wall are provided with and the matched fastening thread of the bolt stem, the braking
Flange of rail face and rectangle tabletting are seamless applying.
In one preferred embodiment of the utility model, the regular polygon lockhole is positive nine, 12,15 or 18 sides
Shape.
The utility model has the beneficial effects that：A kind of bolt looseness provided by the utility model inhibits structure, is clamped in adjustment
After mouth size bolt fastening, it may be convenient to locking locking plate is sleeved on two bolt heads, locking effect is played, utilize simultaneously
Locking locking plate is fixed on bolt head by clamp spring, easy disassembly.
