This turnover bolt device, when the switching of door, be connected to the front or the back side of the bolt seat part on fixed frame side by last latching projection and driven protuberance retaining, automatically turnover bolt is driven towards the lock direction or the direction revolution of unblanking, therefore touch by operability (one touch) goodly, and be used to various fields.
But, when using this kind revolving bolt lock device under the fierce environment of vibration, dead point mechanism is with the frequency of the intrinsic frequency of spring and external vibration when consistent, because accidental this spring that stretches of covibration, turnover bolt promptly towards the direction revolution of unblanking, is lost locking function sometimes.
Still can not lose locking function although therefore the object of the present invention is to provide under vibration environment, simultaneously the available plane handle device of revolving bolt lock of unblanking that touches by realization simple to operate because of the covibration of spring.
Now use the reference symbol in the accompanying drawing to be described as follows: plane handle device of revolving bolt lock of the present invention, be fixed in door 16 handgrip shell 1 holding handgrip 2 imbedding, the base end part of handgrip 2 be installed in the base end part of the top and bottom sidewall of handgrip shell with transverse pivot 3 towards the front face side stretch mode.Suppress revolution handgrip 2 with spring 4 towards the retraction direction with the retraction that is inserted between handgrip 2 and the handgrip shell 1.Hold turnover bolt 14 at the door bolt shell 6 that is based in handgrip shell 1 rear side, the pars intermedia of turnover bolt 14 is installed in the base end part of the top and bottom sidewall of door bolt shell 6 with the fixed pivot axis 9 parallel with transverse pivot 3.
To be based in the base end part front of revolving bolt lock 14 with the last latching projection 18 that fixing bolt seat part 21 back sides of pivot body 17 sides are buckled into disengaging, when door 16 was locked, the driven protuberance 19 that retaining is connected to bolt seat part 21 front face side was based in the leading section front of turnover bolt 14.Front end pars intermedia at the top and bottom sidewall of fastening shell 6 with a bolt or latch sets firmly fixing spring seat 11, sets firmly fluid spring seat 10 between latching projection 18 on the turnover bolt 14 and fixed pivot axi 9.Dead point mechanism (dead point mechanism) is installed on fixing spring seat 11 and fluid spring seat 10 with each terminal part of spring 12, with respect to the straight line that is connected and fixed pivot 9 and fixing spring seat 11, suppress turnover bolt 14 towards the lock direction or the direction revolution of unblanking according to fluid spring seat 10 residing positions.
Jam plate 8 is inserted with slidably state at the grooving 22 of door bolt shell 6 left and right directions, and make the stop recess 13 of bottom of its driven protuberance that is fastened on turnover bolt 14 19 and constraint turnover bolt 14 makes it can not be to the direction revolution of unblanking.Keep with spring 7 by the constraint that is inserted between door bolt shell 6 and the jam plate 8, jam plate 8 is slided towards the direction that can retrain turnover bolt 14 suppress.When turning round, make jam plate 8 slide into the constraint relief position with the operation semi-girder 5 that is based in the handgrip 2 base end part back sides pulling out handgrip 2.Make dead point mechanism keep different mutually with the configuration direction of spring 7 with spring 12 and constraint.
