Abstract
The utility model relates to a car lock mechanism with a link mechanism. A handle (19) on the outside of a car door is connected with one end of a link I (11) on the inner side of the car door, the other end of the link I (11) is connected with a locking pull rod (13), the locking pull rod (13) controls a locking link III (14) connected with a locking mechanism, a key on the outer side of the car door (18) drives an indirect link II (12) to rotate through rotation in a keyhole, the indirect link II (12) controls the rotation of the link I (11), the link I (11) opens or closes the locking mechanism by controlling the locking pull rod (13) and the locking link III (14), and the locking pull rod (13) and the indirect link II (12) are respectively disposed on the two sides of the link I (11). The car lock mechanism reduces one link mechanism, not only enables transmission to be more reliable, but also simplifies the structure, reduces the cost and prolongs the service life, and further brings convenience for installation.
Description
Technical field
The utility model relates to car door lock mechanism, particularly the car door lock mechanism of linkage.
Background technology
In construction machinery, because door lock control separates with lockable mechanism, generally adopt two linkages to connect control between two mechanisms, i.e. the motion that the handle of door lock control and key come the control lock locking mechanism by a linkage respectively separately, complex structure.As Fig. 1, shown in Figure 3, when key 18 was opening, pull handle 19 behind pull bar one 3 pulling connecting rods 34, was pressed lockable mechanism connecting rod 57 by connecting rod 34 again, realizes the unlatching of door lock.When needs are locked, after key 18 rotations, as shown in Figure 2, drive pull bar 25 by connecting rod 22, pull bar 25 drivening rod 46 again rotates, and connecting rod 46 is pushed connecting rod 34 open, passes through handle 19, pull bar 1 again this moment, spurs connecting rod 34 o'clock, the rotation of connecting rod 34 can not pressed lockable mechanism connecting rod 57 again, realizes locking a door.From its structure, the interaction that switch is always met together through a plurality of connecting rods, pull bar could realize switching function, and not only complex structure, cost height, installation are difficult, and has increased the unreliability of transmission.
The utility model content
The utility model provides a kind of car door lock mechanism that only adopts a linkage between door lock, handle and lockable mechanism at the above-mentioned drawback of common door lock, and the variation by structure of the locking mode of original lock machine part is moved on to the key handle place.
As Fig. 3, shown in Figure 5, a kind of car door lock mechanism, described car door lock mechanism is made up of a linkage and a connective pole two; This linkage is made up of connecting rod one, locking pull bar, locking connecting rod three, one end of the connecting rod one that the outer handle of car door and car door are interior is connected, the other end of connecting rod one is connected with the locking pull bar, and locking pull bar one end links to each other with locking connecting rod three, and locking connecting rod three is connected with lockable mechanism; A locking pull bar and a connective pole are respectively in the both sides of connecting rod one.
The outer key of car door drives indirect connecting rod two rotations by the rotation in lockhole, the rotation of a connective pole two control links one, and connecting rod one makes lockable mechanism open or close by control locking pull bar, locking connecting rod three; A locking pull bar and a connective pole two are respectively in the both sides of connecting rod one.
Like this, no matter be to open car door, or key open, lock door with handle, all come the control lock locking mechanism to realize by connecting rod one, this linkage of locking pull bar.
The utility model has reduced by a linkage, not only makes transmission more reliable, and simplifies the structure, reduced cost, improved application life, is convenient to install.

The specific embodiment
As Fig. 3, shown in Figure 5, the utility model door lock mechanism is made up of connecting rod 1, a connective pole 2 12, locking pull bar 13, locking connecting rod 3 14, handle 19 and key 18.One end of the connecting rod 1 in the outer handle 19 of car door and the car door is connected, and the other end of connecting rod 1 is connected with locking pull bar 13, and locking pull bar 13 is controlled locking connecting rods 3 14, and locking connecting rod 3 14 is connected with lockable mechanism.The outer key 18 of car door drives indirect connecting rod 2 12 by the rotation in lockhole and rotates, the rotation of a connective pole 2 12 control links 1, and connecting rod 1 makes lockable mechanism open or close by control locking pull bar 13, locking connecting rod 3 14; A locking pull bar 13 and a connective pole 2 12 are respectively in the both sides of connecting rod 1.
As shown in Figure 3, the connecting rod in the car door lock mechanism 1 is to drive 13 motions of locking pull bar by self rotation.
The utility model is not limited to the foregoing description; in design scope of the present utility model; the description of book according to the above description, those of ordinary skill in the art also can make some conspicuous changes, but these changes all should fall within the protection domain of the utility model claim.
