On 82.First driver 81 drives master arm 82 and coupled arm 83 to rotate, and after switching mechanism is closed completely, master arm 82 can band
Dynamic side rod bearing 5 is moved to the upper end of limiting slot 4.Since the one side of lock tongue 32 is inclined-plane, master arm 82 will drive side rod
When bearing 5 is moved at lock tongue 32, lock tongue 32 can be retracted in lock box 33, when side rod bearing 5 continues to move up, and move past lock
When tongue 32, lock tongue 32 can stretch out under the elastic force effect of spring, and side rod bearing 5 is withstood on to one end of limiting slot 4, side rod bearing
5 are fastened in rotating mechanism, to be latched to rotating mechanism.And unlocking state is wanted, rod assembly 31 only need to be pulled,
It is retracted to lock tongue 32 in lock box 33, then drives the first driver 81, master arm 82 is made to drive dynamic side rod bearing 5 along limiting slot 4
It is rotated to lower end.
Embodiment three
It is to be latched when being fully opened to switching mechanism as shown in Fig. 5, Fig. 6 and Fig. 7, in the present embodiment.Rotating mechanism
Including including master arm 82 and coupled arm 83.Driving mechanism is spring catch 6, and spring catch 6 includes handle 61, shank 62, pin boss 63
With pin shaft 64.Handle 61 is connect with shank 62, is equipped with spring, shank 62 and pin shaft 64 in pin boss 63, spring respectively with shank 62
With 63 phase top of pin boss, shank 62 is connect with pin shaft 64, and pin shaft 64 passes through pin boss 63.Perforation master arm 82 is provided on master arm 82
Mounting hole, and pin shaft 64 can pass through mounting hole.Lockable mechanism is boss 7, and boss 7 includes stage body 71, lockhole 72 and skewed slot 73, lock
Hole 72 is located at the front of skewed slot 73, and lockhole 72 has run through stage body 71.
As shown in Figure 5 and Figure 8, since spring catch 6 is mounted on master arm 82, and boss 7 is installation, is fixed on gearing
On arm 83.When first driver 81 drives master arm 82 and coupled arm 83 to rotate, master arm 82 and coupled arm 83 can be drawn close by side.
So that master arm 82 drives spring catch 6 to rotate, and during this, the pin shaft 64 of spring catch 6 can be from the skewed slot 73 of boss 7 to lock
72 direction of hole is mobile.When switching mechanism fully opens, the pin shaft 64 of spring catch 6 can be inserted in the lockhole 72 of boss 7, thus right
Master arm 82 and coupled arm 83 are limited, that is, are latched to rotating mechanism.
It will be apparent that several improvement or modification made should all regard under the premise of not departing from principle described in the utility model
For the protection scope of the utility model.
