The specific embodiment
Below in conjunction with specific embodiment, further set forth the utility model.Should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model statement, these equivalent form of values fall within the application's appended claims limited range equally.
Embodiment 1
As shown in Figure 2, a kind of automotive seat trench lock locking mechanism, is made up of handle mechanism 1 and latching device 2 two parts, and described handle mechanism 1 is fixedly mounted on cushion frame 3;
Described latching device 2 comprises the positioning housing 21 being fixedly mounted in cushion frame 3 base cross members, in described positioning housing 21, be fastenedly connected lock body by pair of bolts 261, between tapered end 221 and snap close 231, link by the hinged realization of bearing pin 251, on described tapered end 221, be also provided with retracing spring 241, in the present embodiment, retracing spring 241 is extension spring, its one end is fixedly connected on snap close 231, and retracing spring 241 other ends and tapered end 221 are fixedly linked; In the time pulling handle mechanism 1, the bracing wire 14 being attached thereto drives lock body to open and close, the concrete switching relation of lock body and bracing wire is: bracing wire 14 pulls tapered end 221, tapered end 221 drives snap close 231 to open by the spring force of retracing spring, thereby lock body completes opening process one time, remove External Force Acting otherwise unclamp bracing wire 14, under the effect of retracing spring power, snap close 231 closures, handle mechanism 1 is by the tapered end 221 in bracing wire 14 control linkage latching devices 2; In the time that handle mechanism 1 pulls tapered end 221 by bracing wire, tapered end 221 drives snap close 231 to rotate around bolt 261, realizes locking and relieving to trench;
