Specific embodiment one
Automobile door lock of the present utility model please refer to Fig. 1, Fig. 2 and Fig. 3, and it includes lock body shell, left latch hook 7, right latch hook 6, opens driving lever 10, gear driving lever 8 and locking limit body.In Fig. 1, Fig. 2 and Fig. 3, what the top of distance map was nearest is each upper parts of components, upper end and top, and the nearest distance in the left side of distance map is the left end and the right-hand member of each parts.Wherein the left end of gear driving lever 8 is called the tail end of gear driving lever 8 again, and the right-hand member of gear driving lever 8 is called the front end of gear driving lever 8 again.The lock body shell is the housing that is formed by connecting by base 4 and cover plate 2.Upper spring seat 3 and lower spring cup 1 are arranged in the housing of lock body shell, and upper spring seat 3 is positioned at the top of lock body shell, and about respectively have one, lower spring cup 1 is positioned at the lower left side of lock body shell.Respectively with fixing left latch hook 7 of torsion spring and right latch hook 6,, make that left latch hook 7 and right latch hook 6 axle with upper spring seat 3 under the effect of the elastic-restoring force of torsion spring is the axle center rotation on two upper spring seats 3 because torsion spring is flexible.Use torsion spring flexible fastening gear driving lever 8 on the lower spring cup 1 on the left of being positioned at, the tail end of gear driving lever 8 is positioned at lock body enclosure left side, the front end of gear driving lever 8 contacts with the bottom of left latch hook 7 and right latch hook 6, and gear driving lever 8 can be the axle rotation with the axle of lower spring cup 1.Tail end at gear driving lever 8 connects a unlatching driving lever 10, stirs and opens the tail end rotation that driving lever 10 can drive gear driving lever 8.The locking limit body comprises locking limit pull bar 11 and stop screw 5, there is spring the inside of stop screw 5, there is the steel ball that can roll the lower end of stop screw 5, press steel ball, the spring pressurized, in the steel ball retraction stop screw 5, remove pressure, steel ball ejects the lower end of stop screw 5 under the effect of spring force.The part of locking gag lever post 11 is positioned at the lock body enclosure, and other parts are stretched out the outside of lock body shell.The part that locking gag lever post 11 stretches out the lock body housing exterior is provided with locating slot 9, and locating hole 13 is arranged at the bottom of locating slot 9.During use, stir clockwise and open driving lever 10, the tail end of gear driving lever 8 turns clockwise, because gear driving lever 8 is the axle center rotation with 1 of lower spring cup, then the front end of gear driving lever 8 also turns clockwise, make the front end of gear driving lever 8 and the bottom of left latch hook 7 and right latch hook 6 disengage, because left latch hook 7 and right latch hook 6 do not have under the elastic acting force of the active force of gear driving lever 8 and each comfortable torsion spring, make left latch hook 7 be rotated counterclockwise, right latch hook 6 turns clockwise, the top lock tooth of the top lock tooth of left side latch hook 7 and right latch hook 6 deviates from mutually, makes door lock be in enable possition as shown in Figure 1.Push to automotive door this moment, make the center lock shaft of automotive door enter the opening part of left latch hook 7 and 6 formation of right latch hook, a left side latch hook 7 and right latch hook 6 are under the effect of the thrust of the lock shaft of automotive door and torsion spring, head end rotation along gear driving lever 8, left side latch hook 7 turns clockwise, right latch hook 6 is rotated counterclockwise, make that the top lock tooth of the top lock tooth of left latch hook 7 and right latch hook 6 is close mutually, the center lock shaft that is in the automotive door in the lock tooth opening is blocked, and door lock is in fastening position as shown in Figure 2.When automobile door lock is in the position of unlatching, as shown in Figure 3, advance locking gag lever post 11 to the lock body enclosure, make the steel ball of the stop screw 5 lower ends back of in locating slot 9, sliding under the effect of stop screw 5 contained springs, be stuck in the locating hole 13, make locking gag lever post 11 left ends be positioned at the below of gear driving lever 8 front ends.The closing automobile door lock needs left latch hook 7 and right latch hook 6 promotion gear driving levers 8 to turn clockwise, because the below that has locking gag lever post 11 to insert gear driving lever 8 heads, make gear driving lever 8 to rotate, and then the assurance automobile door lock can not closed under the situation that the car owner does not have to note.Equally, when automobile door lock is in the closed position, locking gag lever post 11 left ends are pushed the front end below of gear driving lever 8, when wanting the opening automobile door lock, torsion spring acts on left latch hook 7 and the right latch hook 6, left side latch hook 6 must promote gear driving lever 8 with right latch hook 7 and turn clockwise, because locking gag lever post 11 stops the front end of gear driving lever 8 to turn clockwise, and then makes automobile door lock not open.All make automobile door lock have good theftproof performance.
