Abstract
The utility model relates to an automotive lock running security device used for an automotive lock running mechanism. The device comprises a cam matched with a stop shoulder of the support frame body of the lock, and the cylinder on one end of the cam is axially processed with a slotted hole. The inside of the slotted hole is assembled with an apical plate with a trapezoidal slot by a tensioning spring. The cylinder is processed radically with a rectangular hole, and the inside of the hole is assembled with a barrier chip with a hole in the centre by a return spring. The apical plate passes through the central hole of the barrier chip to make one side of the central hole of the barrier chip lean on the trapezoidal slot of the apical plate, and one end of the barrier chip ejects out of the outer surface of the cylinder. The device has simple structure, easy assemblage, convenient and reliable use.
Description
The utility model relates to a kind of automotive lock driving safety device that is used for the automotive lock mechanism of car.
The automotive lock mechanism of car is the control mechanism of automobile burglar, and automotive lock driving safety device prevents one of safety mechanism of mistake lock when being running, and this part has the effect of control ignition cam stroke, and then control ignition switch and lock lock piece.
The anti-error lock safety device that uses mainly is made up of cam, locking key, stop hook three parts at present.Cam is pushed lock dog by force open, and locking key can not be stretched out by key control lock dog, and stop hook control cam can not be got back to the initial position, and then the control lock dog can not stretch out.If make cam get back to the initial position, must utilize a button to apply a power at the stop hook other end, stop hook is lifted, free control to cam, cam can be got back to original position, and key just can be extracted, and the control of freeing lock dog is lifted in locking key at this moment, lock dog stretches out under the effect of spring, reaches the purpose of lock car.Owing to adopt the stop hook structure to make ignition lock lower bracket body structure complexity, the assembling difficulty must be moved by both hands during use simultaneously, and poor reliability.
The purpose of this utility model provides a kind of simple in structure, easy, easy to use, the failure-free automotive lock of assembling driving safety device.
The purpose of this utility model is achieved in that this device comprises the cam that matches with lock support body shoulder block, axially be processed with flat slotted eye in that cam one end is cylindrical, in slotted eye, utilize tensioning spring assembling one to have the top flat of dovetail groove, radially be processed with slot at cylinder, be with the catch of centre hole in the hole by retracing spring assembling one, top flat passes the catch centre hole, and catch centre hole one side is close in the bottom of the dovetail groove of top flat, catch one end ejects the cam circle cartridge outer surface.
Because the utility model adopts top flat, the catch that fits together, under the tensioning spring effect, top flat stretches out, and make catch one end under action of the spring, eject the cam circle cylinder to be stuck on the shoulder block of lock support body, so cam can not freely rotate, can not get back to original position, lock dog can not stretch out, thereby reaches the insurance purpose that prevents the mistake lock.This installs compared with prior art, and it is simple in structure, and assembling easily, and is easy to use, reliable.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is a kind of concrete structure scheme drawing of the present utility model.
Fig. 2 is the cutaway view of Fig. 1 along the A-A line.
Describe concrete structure of the present utility model and condition of service in detail according to Fig. 1-2.This device comprises the cam that matches with lock support body shoulder block (among Fig. 2 shown in the long and two-short dash line), its cam one end cylinder 2 axially be processed with flat slotted eye, in slotted eye, utilize tensioning spring 3 assemblings one to have the top flat 1 of dovetail groove, radially be processed with slot at cylinder 2, assemble the middle catch 4 that is processed with the oblong centre hole by retracing spring 5 in the hole, top flat 1 passes catch 4 centre holes under the tensioning spring effect, top flat 1 stretches out cylinder 2 axial flat slotted eyes, and a side that makes catch 4 centre holes is under retracing spring 5 effects, be close to bottom at top flat 1 dovetail groove, catch 4 one ends are ejected cylinder 2 outside faces, and act on the shoulder block of lock support body, make cam can not get back to the initial position, lock dog can not stretch out, thereby plays the safety effect that prevents the mistake lock.When the top to top flat 1 applied external force vertically, the inclined-plane of top flat 1 dovetail groove promoted radially square opening of catch 4 withdrawal cylinders 2 by force, and this moment, catch 4 was not subjected to the shoulder block effect, cam is free to rotate, get back to the initial position, key can be extracted, and lock dog stretches out and reaches lock car purpose.After the external force that is added in top flat 1 top is eliminated, under tensioning spring 3 effects, top flat 1 is got back to the home position again, but catch 4 can not be stretched out by the restriction of shoulder block on the lock support body, have only for the second time that forced stroke just can make catch 4 stretch out, make to prevent for the second time the safety position of mistake lock.
