Abstract
The utility model provides an automobile door lock button rolling-ball push rod structure, and belongs to the field of automobile part equipment. The automobile door lock button rolling-ball push rod structure comprises a button (1) and is characterized in that a guide rod (2) is fixed on the inner side of the button (1), and a spherical hinge support is fixed on the other end portion of the guide rod (2). The guide rod (2) is a round hollow pipe, and the spherical hinge support is connected inside the guide rod (2) in an inserted mode. The spherical hinge support is in spherical contact with a connection board on the end portion of the automobile door lock button rolling-ball push rod structure, friction force between the spherical hinge support and the connection board is reduced, the degree of abrasion of the connection board is greatly reduced, the opening travel of an automobile door lock is not affected, and the phenomena that travels are not unified and the automobile door lock can not be opened are avoided.
Description
Technical field
A kind of automobile door lock knob spin pusher structure, belong to the auto parts and components apparatus field.
Background technology
The door lock of automobile is one of automobile very key position, is no matter driving safety at ordinary times or escape while having an accident, automobile door lock in a single day break down all can serious threat to driver and crew's personal safety.Traditional automobile door lock is easy to break down because of wearing and tearing, the thumb-button push rod of the door lock just simple plus screw that adopts serves as, between screw and bolt junction plate, be sliding friction, when knob moves, the knob guide rod promotes the junction plate motion, in whole motion process, the knob push rod contacts with junction plate as the line engagement.This structural friction power is larger, the phenomenon of card during unlatching, often occurs.Because frictional force is larger, after causing opening outside 3000 ~ 4000 times, can, because the long term wear phenomenon causes outer opening travel change, cause outer unlatching to open.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provide a kind of friction little, a kind of automobile door lock knob spin pusher structure of easily opening.
The technical scheme that its technical problem that solves the utility model adopts is: this automobile door lock knob spin pusher structure, comprise button, and it is characterized in that: described button inboard is fixed with guide rod, and the guide rod end is fixed with the spherical linkage bearing.
Described guide rod is hollow circular tube, and the spherical linkage bearing is plugged in guide rod.
Described spherical linkage bearing comprises push rod and is embedded in the ball that can freely rotate on the end face of push rod, and described push rod is comprised of bearing and the threaded rod of straight knurling, and threaded rod is assembled in screwed hole push rod and guide rod are fixed; The front end of bearing is provided with the inlaid hole of indent, and ball is embedded in inlaid hole.
The height that described ball exposes inlaid hole is 1/2nd of ball radius.
The part ball that is exposed and junction plate sphere-contact, form rolling friction between ball and junction plate while pressing button.
Compared with prior art, the beneficial effect that has of a kind of automobile door lock knob spin pusher structure of the present utility model is: in the utility model, ball is set in push rod, and ball can freely rotate in push rod, and this structure is the spherical linkage bearing.When knob moved, ball and junction plate were sphere-contact, after ball is stressed, can in push rod, rotate, thereby offset the friction of a part from junction plate.While unblanking, frictional force is little, during outer handle opening door lock, exerts oneself light and to open whole process smooth and easy.The utility model end is that spherical linkage bearing and junction plate are sphere-contact, greatly reduces the junction plate degree of wear, guarantees that opening travel is unaffected, thereby solves stroke disunity, the phenomenon that can't open.Increase driver and crew's life security guarantee.
The accompanying drawing explanation
Fig. 1 is a kind of automobile door lock knob spin pusher structure assembling schematic diagram.
Fig. 2 is that a kind of automobile door lock knob spin pusher structure splits schematic diagram.
Fig. 3 is a kind of ball of automobile door lock knob spin pusher structure and the partial cross section figure of push rod.
Wherein: 1, button 2, guide rod 3, push rod 4, ball 5, threaded rod 6, bearing 7, screwed hole.
The specific embodiment
Fig. 1 ~ 3rd, the most preferred embodiment of a kind of automobile door lock knob of the utility model spin pusher structure, be described further below in conjunction with 1 ~ 3 pair of the utility model of accompanying drawing.
With reference to accompanying drawing 1 ~ 3: automobile door lock knob spin pusher structure of the present utility model, by button 1, guide rod 2, push rod 3, ball 4, formed, button 1 inboard is fixed with guide rod 2, and guide rod 2 is hollow circular tube, and inside is screwed hole 7; The other end of guide rod 2 is fixed with push rod 3, and push rod 3 first halfs are the bearing 6 of straight knurling, and latter half of is threaded rod 5; Threaded rod 5 and screwed hole 7 couplings, it is interior that push rod 3 and guide rod 2 is fastening that threaded rod 5 all is assembled to screwed hole 7; The end of bearing 6 is the inlaid hole of indent, in inlaid hole, inlays ball 4, and it is 1/2nd of radius that ball 4 is exposed at the outer height of inlaid hole.The part ball 4 and the junction plate sphere-contact that are exposed, form rolling friction between ball 4 and junction plate while pressing button 1.
The material of button 1 and guide rod 2 is all higher plastics of metal or hardness and toughness; Push rod 3 and ball 4 material be steel.Guide rod 2 adopts screw threads for fastening with push rod 3, when a part is damaged therein, can only change this one, without whole replacements.Also can reduce the use of steel, economize on resources, reduce costs.
On push rod 3, design straight knurling, being convenient to that push rod 3 and guide rod 2 be spirally connected is that the folder of device is pinched.
Concrete using method is as follows: automobile door lock knob spin pusher structure can be made according to required stroke, directly replaces existing door lock by twisting structure.The spherical linkage seat structure that push rod 3 and ball 4 form is plugged in guide rod 2, ball 4 is against on junction plate, while pressing button 1, ball 4 is accepted the plate that is dynamically connected of trying hard to recommend of guide rod 2 and push rod 3 conduction and is controlled lock core, with junction plate generation rolling friction, under sphere-contact, use for a long time the junction plate wearing and tearing little, can not affect design runlength.
The above, it is only preferred embodiment of the present utility model, be not the utility model to be done to the restriction of other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the equivalent embodiment of equivalent variations.But every technical solutions of the utility model content that do not break away from, to any simple modification, equivalent variations and remodeling that above embodiment does, still belong to the protection domain of technical solutions of the utility model according to technical spirit of the present utility model.
