Abstract
The utility model provides an automobile door lock's fore shaft device, it has two clamp lamella shape locking pieces and a front end has the lever of trapezoidal kicking block, the locking piece front end has the arc notch, the rear end has the obtuse angle breach, the locking piece is installed relatively, can merge and open, the arc notch becomes the ellipse during merging, the obtuse angle breach becomes the dovetail groove, locking piece and lever all receive the effect of spring force, the arc concave door of two locking pieces can press from both sides the cylindrical hasp on the door frame during locking the door, the trapezoidal kicking block of lever front end inserts the dovetail groove because of the effect of spring force simultaneously, make the locking piece can not open, pull out trapezoidal kicking block when opening the door, the locking piece opens because of the effect of spring force, make the hasp deviate from, and open the door.
Description
The utility model relates to automobile door lock, particularly the fore shaft device of automobile door lock.
The fore shaft device of existing automobile door lock, comparatively advanced and commonly used is the forked type lock dog formulas that two forks are arranged, and glass type lock dog is porose, is positioned on axle and goes up and can rotate, and the prong that can make the forked type lock dog is outwards or make progress (or downward).When car door opening, the prong of forked type lock dog is outside, at closing time, one fork because of the garden cylindricality snap close bump fork-shaped lock dog on the car frame, the forked type lock dog rotates, and makes prong upwards (or downwards), and withstands the fork-shaped lock dog with a jacking block it can not be rotated, at this moment the garden cylindricality snap close on the car door frame is contained in the prong of fork-shaped lock dog, makes it can not deviate to make and locked because of stopping of another fork.The shortcoming of this fore shaft device is when on the car door lock, owing to latch in the prong, when vehicle ' is jolted, car door can be up and down, thereby car door closely is connected with the car frame, also causes the wearing and tearing of snap close and prong simultaneously, during serious wear, more influence door shutting, for this reason, be lined with wear resistant resin on some prong, but complex process, cost is higher, and when resin wearing, door interlock switch is not freely.
The purpose of this utility model is for overcoming a kind of car door and close-connected fore shaft device of doorframe of making that above-mentioned deficiency proposes, and jolts when travelling at vehicle, and car door also can be movable.
The utility model is realized with the following method.
The fore shaft device has two folder lobe shape lock dogs and front end that the lever of trapezoidal jacking block is arranged, they are installed on three axles of a steel plate, and can rotate around the axis, and the front end of folder lobe shape lock dog has arc-shaped notch, there is the obtuse angle breach rear end, and two folder lobe shape lock dogs are installed also relatively and can be merged or open.During merging, the arc-shaped notch of front end becomes ellipse garden shape; The obtuse angle breach of rear end is groove in echelon, the trapezoidal jacking block of lever front end can insert or withdraw from dovetail groove, two folder lobe shape lock dogs all are connected with spring and make folder lobe shape lock dog be subjected to one to make its open power, and the lever front end also is connected with spring, makes trapezoidal jacking block be subjected to the power that can insert it into dovetail groove.The fore shaft device is installed on the car door, in the time of on car door lock, two folder lobe shape lock dogs merge, the ellipse garden shape that the arc-shaped notch of front end is merged into is lived the garden cylinder locks clip on the car door frame, the trapezoidal jacking block of lever front end inserts the dovetail groove of two folder lobe shape lock dog rear ends because of the effect of spring force, make folder lobe shape lock dog can not rotate and make car door locking, transfer to trapezoidal jacking block when opening the door, two folder lobe shape lock dogs open because of the effect of spring force, garden cylindricality snap close on the car door frame is deviate from, car door can be opened, garden cylindricality snap close on the car door frame clashes into the bottom of the arc-shaped notch of open two folder lobe shape lock dogs at closing time, two folder lobe shape lock dogs are merged, clamp the garden cylindricality snap close on the car door frame, the trapezoidal jacking block of lever front end inserts in the dovetail groove of two folder lobe shape lock dog rear ends because of the effect of spring force simultaneously, two folder lobe shape lock dogs can not be rotated, and pin car door.
The utility model has the advantages that:
1, in the time of on car door lock, because the arc-shaped notch of two folder lobe shape lock dog front ends are tight the garden cylinder locks clip on the car door, car door closely is connected with doorframe, even jolt when travelling at vehicle, car door can not become flexible yet.
2, owing to use for a long time, when arc-shaped notch and garden cylindricality snap close caused wearing and tearing, trapezoidal jacking block can deeper insert in the dovetail groove because of the effect of spring force, and the wearing and tearing that automatic compensation is caused make fore shaft be in the state of clamping all the time.
The utility model is described in further detail below in conjunction with accompanying drawing.
Schematic diagram when Fig. 1 is the merging of fore shaft device.
Fig. 2 is the schematic diagram of fore shaft device when opening.
The fore shaft device is to make with steel, Fig. 1, among Fig. 2, the fore shaft device is for being fixed with three axles 3 on a block plate 14,4,6, at axle 3,4 are separately installed with two folder lobe shape lock dogs 1,2, on the axle 6 lever 5 that front end has trapezoidal jacking block 13 is installed, two folder lobe shape lock dogs 1,2 and lever 5 respectively can be around axle 3,4,6 rotate, folder lobe shape lock dog 1,2 front end has arc-shaped notch, there is the obtuse angle breach rear end, the rear end also has spring 9,10 jack, two folder lobe shape lock dogs when mounted, arc-shaped notch is relative, when two arc-shaped notch are merged into ellipse garden shape, two obtuse angle breach are merged into dovetail groove, at pin 7, spring 9 is installed on 8,10,11,12, spring 9,10 make two folder lobe shape lock dogs be subjected to resilient force to be in open position, spring 11,12 act on the front end of lever 5, make the trapezoidal jacking block of lever 5 front ends be inserted the power of dovetail groove direction.
Among Fig. 2, the fore shaft device is when opening, and two folder lobe shape lock dogs 1,2 open because of the effect of spring 9,10.
The fore shaft device is installed on the car door, when closing car door, garden cylindricality snap close bump folder lobe shape lock dog 1 on the car door frame, 2 arc-shaped notch bottom and make two folder lobe shape lock dogs 1,2 overcome spring 9,10 elastic force and around axle 3,4 rotate, make two arc-shaped notch be merged into ellipse garden clevis and live garden cylindricality snap close on the car frame, two press from both sides lobe shape lock dogs 1 simultaneously, the obtuse angle breach of 2 rear ends is merged into dovetail groove, the trapezoidal jacking block 13 that makes lever 5 front ends is because of spring 11,12 resilient force and inserting in the dovetail groove, make two folder lobe shape lock dogs 1,2 can not rotate, and on the car door lock.When driving door, with manual external force shifting lever 5, trapezoidal jacking block 13 is upwards withdrawed from from dovetail groove, two folder lobe shape lock dogs 1,2 open because of the effect of the elastic force of spring 9,10, garden cylindricality snap close on the car door frame is deviate from from the fore shaft device, car door can be opened.
