Description
Technical field:
The utility model relates to the technical field of lock, refers in particular to a kind of tapered end pole socket that is used for the automobile central authorities control door lock of various vehicles such as car, truck and improves structure.
Background technology:
Automobile is development by leaps and bounds along with science and technology development; Through the times short by one, two a century, from initial very simple and crude carriage, develop into nowadays, various, multiple functional automobile all can buy on market; Nowadays, it is used by increasing people as people's traffic by land, vehicle.Automobile central authorities control door lock as an automobile part though its composition that occupies in the value of automobile is very little, waits the very important effect of bringing into play for the safety of protecting automobile; But, just still there is structural defective in automobile central authorities control door lock in the market, as its tapered end pole socket that links to each other with the tapered end bar, by be set in screw rod on slide block fixedly connected, the motor in the housing rotates by the gear driven screw rod, when screw rod rotates, screw thread on the screw rod makes the slide block that cooperates with it move along screw axis, the tapered end pole socket is realized the control to the door lock open and close along with slide block moves up and down, after the control of unblanking that realizes door lock, and the motor outage; Because the inertia of motor can not stop operating immediately, also can continue to drive screw rod and rotate, make slide block drive the tapered end pole socket and continue the pushing housing; So, be easy to housing to be pushed bad, and make control door lock lose its function; Like this, make troubles to the user on the one hand, also increased user's use cost on the other hand.In addition, when motor breaks down when stopping not change, because the tooth on the motor output shaft meshes with the tooth on the gear, screw rod can not rotate, and the tapered end pole socket of fixedlying connected with slide block can not move up and down, and causes deadlock phenomenon, may produce the locked situation of car door, make troubles to the user.
Summary of the invention:
But the purpose of this utility model is exactly the tapered end pole socket of the automobile central authorities control door lock of a kind of clutch of providing at the deficiencies in the prior art part improves structure.
For achieving the above object, the utility model comprises: screw rod, supporting base, screw bolt seat, gear, motor, slide block, the tapered end pole socket, housing, screw bolt seat is fastened in the groove of housing, screw rod one end is fixed on the housing by screw bolt seat, its other end is fixedlyed connected with gear, screw rod one end has the projection on the interior supporting base of a circular hole and the draw-in groove that is installed in housing to socket-connect, the cylinder of the other end matches with circular hole on the screw bolt seat, the tooth of gear is meshed with tooth on the motor output shaft that is fixed in the housing, slide block matches with thread segment on the screw rod, is arranged in the mutual inlay card of two projections of the inboard symmetrical molding of two projections on the slide block in the guide groove of housing and tapered end pole socket.Screw rod is threadless cylindric away from gear one end.Be installed with the buffering block on the end that screw rod is fixedlyed connected with gear.
After adopting said structure, but the utility model adopts the tapered end pole socket that has the projection clutch to realize open and close control to door lock, and when slide block will move on to screw tip on the screw thread on the screw rod, the lateral margin of tapered end bar was withstood no longer mobile by housing; At this moment, the tapered end bar that links to each other with the tapered end screw rod is opened lock; Projection on the slide block backs down the projection on the tapered end pole socket, and move to the opposite side of the projection on the tapered end pole socket, can not push housing bad, in addition, when breaking down, motor stops not change when causing deadlock phenomenon, it being separated for pressure of tapered end pole socket of clutch can freely move up and down, drive the tapered end bar lock is opened with slide block.Use the utility model make the reliability of automobile central authorities control door lock improve greatly, durable in use.

Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is the part figure of the utility model screw rod;
Fig. 3 is the utility model screw bolt seat stereogram;
Fig. 4 is the three-dimensional exploded view of the utility model tapered end pole socket and slide block;
Fig. 5 is a three-dimensional assembling drawing of the present utility model.
The specific embodiment:
Shown in Fig. 1～5: the utility model comprises: screw rod 1, supporting base 2, screw bolt seat 3, gear 4, motor 5, slide block 6, tapered end pole socket 7, housing 8, screw bolt seat 3 is fastened in the groove 82 of housing 8, screw rod 1 one ends are fixed on the housing 8 by screw bolt seat 3, its other end is fixedlyed connected with gear 4, screw rod 1 one ends have the projection 21 on the supporting base 2 in a circular hole 11 and the draw-in groove 83 that is installed in housing 8 to socket-connect, the cylinder of the other end matches with circular hole 31 on the screw bolt seat 3, the tooth of gear 4 be fixed on housing 8 in motor 5 output shafts on tooth be meshed, slide block 6 matches with thread segment on the screw rod 1, is arranged in two projections, the 71 mutual inlay cards of two projections 61 and the inboard symmetrical molding of tapered end pole socket 7 on the slide block 6 in the guide groove 81 of housing 8.Screw rod 1 is threadless cylindric away from gear 4 one ends.Be installed with buffering block 9 on screw rod 1 and the end that gear 4 is fixedlyed connected.
When using the utility model, rotate by switch control motor 5, because the gear on the tooth of gear 4 motor 5 output shafts interior with being fixed on housing 8 is meshed; Therefore, gear 4 is being driven by motor 5 and is rotating; Because screw rod 1 is fixedlyed connected with gear 4; So when gear 4 rotated, screw rod 1 also can be along with rotation, the slide block 6 that matches with thread segment on the screw rod 1 is along with the rotation of screw rod 1 is moved along screw rod 1 axis; Two projections 61 on the slide block 6 withstand the projection 71 on the tapered end pole socket 7, and tapered end screw rod 7 is moved thereupon; When motor 5 was just changeing, slide block 6 moved to the direction away from gear 4, and drove tapered end pole socket 7 and move thereupon, and when slide block 6 will move on to screw tip on the screw rod 1, the lateral margin of tapered end screw rod 7 was withstood no longer mobile by housing 8; At this moment, the tapered end bar that links to each other with tapered end screw rod 7 is opened lock; Projection 61 on the slide block 6 backs down the projection on the tapered end pole socket 7 71, and moves to the opposite side of the projection 71 on the tapered end pole socket 7, can not cause tapered end pole socket 7 that housing 1 pushing is bad; The switch of control motor 5 cuts out; But because the inertia of motor 5, slide block 6 continues to move to screw tip on the screw rod 1 along screw rod 1 axis by original direction; But because screw rod 1 is cylindric away from gear 4 one ends; Like this, although motor 5 may be rotated further, because slide block 6 has moved to the screw tip on the screw rod 1, screw rod 1 forms idle running, and slide block 6 is no longer mobile; When motor 5 counter-rotatings, slide block 6 also oppositely moves, because when motor 5 is just changeing, projection 61 on the slide block 6 has moved to the opposite side of the projection 71 on the tapered end pole socket 7, making slide block 6 drive tapered end pole socket 7 also oppositely moves, thereby will pin, in addition, when motor 5 breaks down when stopping not change, with meshed gears 4 on motor 5 output shafts and on screw rod 1 can not rotate, when causing deadlock phenomenon, because the tapered end pole socket 7 that is connected with slide block 6 is structures of clutch, when giving its pressure, projection 71 on the tapered end pole socket 7 moves to the opposite side of the projection 61 on the slide block 6, tapered end pole socket 7 separates with slide block 6, can freely move up and down, and drives the tapered end bar lock is opened.
