Description

Padlock

A kind of padlock is a kind of improvement that it is carried out uniformly for the presentation quality of improving padlock by the electrodeposited coating covering on structure design.

Padlock outward appearance of the prior art is beautified generally and is sprayed paint, and lacquer easily comes off, influence lock attractive in appearance.The purpose of this utility model is that the surface lacquer that becomes traditional covers a kind of novel pad lock structure that provides into electroplating.

The utility model design philosophy is that Fastener and control member are packed into from lock core hole after lock body is electroplated.

The purpose of this utility model can reach by following measure: mainly in the padlock of being made up of lock body, lock bridge, steel ball, control position piece, return spring and lock bridge spring, lock core radially offers slot, and control strip is housed respectively in its hole.With slot side by side corresponding setting circular port is arranged, place the control strip spring in the hole respectively.Control strip be with lock core on the slot size match and be incorporated in a rectangle body that equates with lock core diameter on the length, have the slot that passes for key on it, the position in hole and size adapt with the thickness of key on width, be on being stuck in the corresponding tooth of key the time in the longitudinal direction, the two ends of control strip do not exceed lock core diameter.Control strip has a little tooth that protrudes on every limit, direction both sides of its width.The control strip spring withstands on wherein the little tooth, and a shutoff pressure ring is arranged on the lock core hole of lock body bottom surface.

Accompanying drawing 1 is overall structure master's sectional view of padlock.

Accompanying drawing 2 is left views of padlock.

Accompanying drawing 3 is structure charts of control strip.

Below in conjunction with accompanying drawing embodiment of the present utility model is described further: offer two holes above the lock body (1) for putting into lock bridge (2).Long and short opposed inside symmetry of lock bridge (2) respectively open an arc notch, the diameter of the size of its breach and steel ball (3) adapts.On drawing money on credit, open an arc-shaped ring groove, a lock bridge spring (9) is arranged below drawing money on credit near head.Vertical with the bottom surface lock core hole of opening in the bottom of lock body (1) is placed lock core (5) in the lock core hole.Lock core (5) radially has slot, control strip (6) is housed in its hole, with slot side by side corresponding setting circular port is arranged, place control strip spring (10) in the hole, control strip (6) be with lock core on the slot size match and be incorporated on the length a cuboid with lock core (5) equal diameters, have the slot that passes for key on it, the position in hole and size adapt at width and key thickness; The two ends that are control strip (6) on being stuck in the corresponding tooth of key the time in the longitudinal direction do not exceed lock core (5) diameter.There is a little tooth that protrudes on every limit on the both sides of control strip (6) width, and control strip spring (10) withstands on wherein on the little tooth.On the lock core hole of lock body (1) bottom surface shutoff pressure ring (8) is arranged.Steel ball (3), control position piece (4), lock core (5) and return spring (7) are put into by lock core hole.Steel ball (3) enters the transverse holes of lock body (1) after lock core hole is put into, and the control position piece (4) that is placed into separate to about each one.Protrusion cylinder on lock core (5) top cooperates with hole on piece (4) bottom surface, control position.Control strip (6) and control strip spring (10) are pre-assembled on the lock core (5) and lock core (5) is together put into lock core hole.Shutoff pressure ring (8) is in the end to press solidly on lock core hole.

The utility model padlock is work like this: press down lock bridge, lock bridge spring retraction, when steel ball is just in time aimed at arc notch on the lock bridge, control position piece is owing to lost the restraint forces of steel ball, under the effect of return spring and lock core, turn to locked position of coupler (the corresponding steel ball in the face of cylinder of control position piece), steel ball blocks lock bridge, and lock core resets simultaneously, and lock is in closed condition.When key inserts lock body, the slot of key extruding control strip, and the cooperation of the position by shaped as key bit and control film perforation to adjust the termination and the lock core diameter of control strip consistent, make lock core be in rotatable state, when rotational lock core drive control position piece turns to lockset position of coupler (the groove location correspondence steel ball of control position piece), steel ball partly enters in the groove, removed the power that holds of lock bridge, lock bridge is upspring under the lock bridge spring action, when upspringing to being blocked by steel ball when contacting, thereby make lock bridge can not eject lock body with the draw money on credit arc-shaped ring groove of termination portion of lock bridge.The back opened by lock because steel ball enters the groove of control position piece, and beam control position piece rotates approximately, and then the rotation that has limited lock core can not reset it, and this moment, key was stuck on the lock body by control strip.

The utility model has replaced pellet shot from a slingshot with control strip, removed corresponding pilot hole on the lock body from, and all control members of lock can be electroplated the back in surface of lock body and pack at last from lock core hole, make the surfacing of lock body, adapt to and electroplate, improved the presentation quality of lock, compare with padlock in the prior art and to have: be specious, easily processing, the tensile strength height of lock, advantage such as safe and reliable.

Claims (1)
