The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
Referring to Fig. 3 to Fig. 6.
A kind of door lock assembly is provided, and it comprises lock body, lock core 22, securing rod (comprising label 27 and 28) and is located at door-plate connecting hole 24 on the door-plate 23 that lock body comprises the lock body connecting hole; Described lock core 22 comprises lock core arm 26, and lock core arm 26 comprises lock core arm connecting hole (comprising label 29 and 30) again; Securing rod is plugged in door-plate connecting hole 24, lock core arm connecting hole and the lock body connecting hole; Securing rod comprises that the last securing rod 27 of two-part reaches securing rod 28 down, and securing rod 27 plugs and connects door-plate connecting hole 24 and lock core arm 26 on this, and following securing rod 28 plugs and connects lock core arm 26 and lock body connecting hole.Lock core arm connecting hole correspondence comprise the first lock core arm connecting hole 29 and the second lock core arm connecting hole 30.Last securing rod 27 plugs and is connected in the described door-plate connecting hole 24 and the first lock core arm connecting hole 29, and following securing rod 28 plugs and is connected in the second lock core arm connecting hole 30 and the lock body connecting hole.
The utility model one preferred embodiment is that securing rod 27 is the elongate rod of a bending on this, comprises first connecting portion 31 and second connecting portion 32; First connecting portion 31 is plugged in the described door-plate connecting hole 24, and described second connecting portion 32 is plugged in the described first lock core arm connecting hole 29; The straightway of first connecting portion, 31 ends is greater than the straightway of second connecting portion, 32 ends.Following securing rod 28 is the elongate rod of a bending, comprises the 3rd connecting portion 33 and the 4th connecting portion 34; The 3rd connecting portion 33 is plugged in the second lock core arm connecting hole 30, and the 4th connecting portion 34 is plugged in the lock body connecting hole; The end of the 3rd connecting portion 33 and the 4th connecting portion 34 includes a straightway.Second connecting portion 32 can drive lock core arm 26 and rotate, and drives the 3rd connecting portion 33 by lock core arm 26 again and rotates; The 3rd connecting portion 33 can drive lock core arm 26 and rotate, and drives second connecting portion 32 by lock core arm 26 again and rotates.
The operating principle of the utility model door lock assembly is: securing rod is designed to two sections, and the hole that the lock core arm connects securing rod is designed to two holes, and last securing rod is connected with the second lock core arm connecting hole by the first lock core arm connecting hole respectively with following securing rod.After last securing rod presses down, last securing rod drives the lock core arm and rotates, the lock core arm rotates and drives securing rod promotion lockplate down, lockplate drive brace moves upward and makes brace can not block the connecting shaft piece, this moment lock body be in locked state, if not pull-up securing rod from interior from outside all can not open door lock.After pressing down, securing rod closes the door, dead bolt rotates the connecting shaft piece that drives on the pawl axis, the connecting shaft piece promotes the brace on the lock body, brace promotes lockplate, lockplate promotes down, and securing rod moves upward, following securing rod promotes the lock core arm, and the lock core arm rotates that driving locks to be decided bar and spring back to the origin-location, and whole anti-error lock function is realized.
By adopting last securing rod and the following securing rod of securing rod being made two-part, and the corresponding with it first lock core arm connecting hole and the second lock core arm connecting hole of on the lock core arm, being provided with, thus with former lock body, lock core, it is fixing that the door-plate connecting hole fixedly is improved to 2 of present two-parts to 3 of securing rod, one section is to go up securing rod to connect the door-plate connecting hole and the first lock core arm connecting hole, another section is the second lock core arm connecting hole and the lock body connecting hole of securing rod connection down, this mode has realized increasing the free scope of activities of securing rod, thereby reduce the accuracy of manufacture requirement of door-plate, the inefficacy that solves anti-error lock function simultaneously.If use the locking means of the utility model door lock assembly, it is more convenient to use during the door lock of locking vehicle, and is difficult for taking place the phenomenon of anti-error lock, simultaneously the inefficacy of using false-locking prevention method also can solve anti-error lock function.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
