Specific embodiment
As shown in figure 1, doll carriage locking device, the doll carriage includes handle 20, foreleg 60 and back leg 10, as schemed
Shown in 2, the locking device includes upper joint 2, front joint 6, posterior joint 1 and latch fitting 3, the upper joint and the handle end
Connection, the front joint is connected with the foreleg end, and the posterior joint is connected with the back leg end, the posterior joint and institute
The both sides that front joint is rotatably connected at respectively the upper joint are stated, specifically forward and backward joint Jing rivets are hinged rotation and install
In the both sides of upper joint 2, therefore forward and backward joint can be rotated by being hinged relative to upper joint 2.
The middle inside in the front joint 6 is provided with rivet post 62 with holes, and the middle part of the posterior joint 1 is provided with rivet hole
12, the lock gear 4, latch fitting 3, upper joint 2 are sheathed on the rivet post 62, and the posterior joint engages with the upper joint
Afterwards the rivet hole is just to the rivet post, through there is rivet among the rivet hole and the rivet post.By rivet
Realize that forward and backward joint Jing rivets are hinged and rotate the both sides for being installed on upper joint 2.
The latch fitting is located between the front joint and the upper joint, as shown in figure 4, the side of the upper joint 2 sets
There is the first unidirectional angle 21, as shown in figure 3, the inner side of the posterior joint 1 is provided with locked groove 11, as shown in figure 5, the latch fitting one
Side is provided with the angle 31 of lock pin 32 and second, and second angle matches with first angle, first angle, described
Two angles are the groove-like structure with straight slope or curvilinear plane.Pulling side of first angle towards the draught line
To inclination, to realize the pulling of draught line.The lock pin is circular or square, and lock pin can rear pass described in locking with during locked groove grafting
The rotation of section, the afterbody of the latch fitting is connected with draught line 8, and the latch fitting is by the draught line and is located at the handle top
Regulation switch connection, press regulation switch can pull draught line, be provided with lock gear between the latch fitting and the front joint
4, the lock gear is provided with cannelure towards the side in the front joint, and spring 5, the work of spring 5 are provided with the cannelure
Lock gear 4 and front joint 6 are firmly put on, as shown in fig. 6, the inner side in the front joint 6 is provided with and the lock gear phase
The teeth groove of matching, the upper joint is provided with the teeth groove matched with the lock gear in the periphery of first angle.
Latch fitting 3 lock simultaneously or while release posterior joint 1, front joint 6 relative to upper joint 2 rotation, so as to realize joint
Folded state and deployed condition between conversion.As shown in figs, posterior joint 1 and front joint 6 are relative to upper joint 2
It is in released state to rotate simultaneously, and lock pin 32 departs from the locked groove 11 inside posterior joint 1, and lock gear 4 departs from inside upper joint 2；Such as
