Background technique
Make the fastening anti-loose problem of member with bolt,, do not reach optimal effect all the time through test of many times.
Especially No. 200520121903.1 patents of in September, 2005 application " in establish the locking release screw bolt of taper pin friction lock compact form ", through authoritative department anti-loosening property check remnants/primitive axis power minimum 86%, the highest by 94.2%, average 88.8%, still do not reach the optimum efficiency more than 96%.And lock pin is thin, very easily damages, so require further improvement.
02209486.5 " supporting the locking release screw bolt of the friction type " of application before this, disclosed is to concentrate the position punching at stress, and shortcoming is that the little pin in hole does not return frangibility.02238327.1 " tightening the locking release screw bolt of friction type, " is disclosed to be grooving on screw rod, has destroyed the stress of screw rod.
Summary of the invention
The purpose of this utility model is to allow member after use this " the locking release screw bolt of self-bring in type " is fastening, can reach best anti-loosing effect, and release is easy to processing freely, and cost is low.
Main technical schemes, measure: by external screw rod (1), outside thread (2), bolt head (3), inner screw (4), lock pin (5), screw head (6), loose-proof sleeve (8), ball (9), spring (10), spring clip (11), form the locking release screw bolt overall structure of self-bring in type.
Feature is that its hollow part connects by the inner screw (4) that is followed successively by screw head (6), inner screw (4), screw thread (19), top (20), formation one by the hollow bolt that is followed successively by outer bolt (3), external screw rod (1), outside thread (2), lockpin hole (12) formation one.The end of bolt is provided with the locking release mechanism that is made of lock pin (5), ball (9), spring (10), spring clip (11).
Locking release mechanism be on outside thread (2), radially connect 2 or 3 or 4 lock pins (5), be the bolt side end face at outside thread (2) again, axially connect and lock pin corresponding 2 groups or 3 groups or 4 groups of balls (9), spring (10), spring clip (11).
Form best configuration by 3 lock pins (5) and 3 groups of balls (9), spring (10), spring clip (11) in the locking release mechanism, it is that 120 degree are divided equally that angle is set.
Form the interior shape of bolt successively by the hole of bead (13), draw-in groove (14), through hole (15), slide opening (16), internal thread (17), pilot hole (18) from the B apparent direction.
The C apparent direction is formed the structure shape of inner screw (4) successively by top (20), screw rod (4), screw thread (19), screw rod (6), interior hexagonal hole (7), the angle of its top (20) is that ∠ 1 is 35～38 degree.
Lock pin (5) one end flat, an end is top shape, its ∠ 2 is 142～145 degree, best 144 degree.Lock pin footpath portion establishes semicircle orifice (21).
At the ∠ 1 of top (20) and the top ∠ 2 of lock pin (5), when being complementary, angle is in the sliding engaged state.
Between the screw head (6) of inner screw (4) and the pilot hole (18) of bolt, connect loose-proof sleeve (8).The multiple shape of lock pin 5 design, comprise cylindrical, square, rectangular, triangle etc.
In sum, the utlity model has simple in structurely, anti-loosing effect is real to go out characteristics such as convenient for unlocking.Initial survey: remnants/primitive axis power is minimum 96%, and is the highest by 99%.
