Self-locking folder further includes sliding shackle mechanism, and the self-locking boss engages or is detached from the sliding shackle mechanism.
The sliding shackle mechanism includes push button, buckle and spring, and the handle is equipped with installation through-hole, the push button packet
Push button ontology and the protrusion on the medial surface of the push button ontology are included, the push button ontology is located on the outside of handle, described convex
It rises and is located in installation through-hole, the buckle is located at the inside of handle, and the buckle includes buckle ontology and is set on buckle ontology
Hook, it is described buckle ontology be fixed on protrusion end face on, the spring be set to protrusion top surface and installation through-hole roof it
Between, hook and self-locking convex decometer on the buckle are closed or are detached from.
The outer end face of the self-locking boss is the first arc convex, and the outer end face of the buckle is convex with first arc
The second arc convex that face matches.
The free end of the top connection and one end of connecting rod are connected by shaft.
The self-locking boss is made of symmetrical and spaced first part and second part, and the of the self-locking boss
A part and second part are equipped with coaxial through-hole, and one end of the connecting rod is located at the first part and second of self-locking boss
Between part, the shaft be fixed on one end of connecting rod and with it is logical in the first part and second part of the self-locking boss
Hole matches.
The utility model is when being unfolded self-locking folder, it is only necessary to sliding shackle mechanism, so that self-locking boss and slide lock
It is deployable self-locking folder that buckle mechanism, which is detached from, simple to operate.

Specific embodiment
As shown in Figure 1, the self-locking folder proposed in the utility model embodiment, including top connection 10, lower contact 20,
Handle and connecting rod, top connection 10 are connect with vertical tube 30, and cross handle is installed on vertical tube 30, and lower contact 20 is connect with vehicle frame head 40.
As shown in Fig. 2, top connection 10 has connecting pin and free end, lower contact 20 has connecting pin and free end, above connects
First 10 connecting pin and the connecting pin of lower contact 20 are hinged, and the free end of lower contact 20 is connect with the lower rotational of handle 50, this
In embodiment, the free end of lower contact 20 is connect with the lower part of handle 50 by pin 80.The free end of top connection 10 and connecting rod
60 one end rotation connection, the other end of connecting rod 60 and the top of handle 50 are rotatablely connected, and the free end of top connection 10 is equipped with
Self-locking boss 11.Self-locking folder further includes sliding shackle mechanism, and self-locking boss 11 engages or is detached from sliding shackle mechanism, from
And realize that top connection is connected with lower contact and the separation of top connection and lower contact (folding and self-locking folder and is unfolded self-locking
Folder).When self-locking folder is unfolded, it is only necessary to sliding shackle mechanism, so that self-locking boss and sliding shackle mechanism are detached from
I.e. deployable self-locking folder, it is simple to operate.
As shown in Figures 3 to 6, sliding shackle mechanism includes push button 71, buckle 72 and spring 73, and handle 50 is equipped with installation
