The specific embodiment
For the utility model content, structure, feature are had further understanding and understanding, existing conjunction with figs. and
Embodiment is described as follows:
Be that example further specifies the utility model now with a kind of U type list padlock.
Consult Fig. 1, a kind of U type list padlock comprises a lock body 2 and a block piece 1, and this block piece 1 has first end 11 of being located at lock body 2 primary importances 21, second end 12 that reaches insertion lock body 2 second places 22, and this second end 12 has a recess 13.
Consult shown in Fig. 2,3, this locked mechanism comprises:
One lockhole 3 is located on the lock body 2, with second end 12 of ccontaining block piece 1;
One core groove 4 is located on the lock body 2, adjacent to this lockhole 3, and has first space 41 and second space 42 that is connected;
One via 5 is located on the lock body 2, to be communicated with first space 41 of this lockhole 3 and core groove 4;
One liftout attachment 6, be located in the lockhole 3, to eject second end 12 of block piece 1, this liftout attachment 6 comprises a jacking block 61, a compression spring 62, these jacking block 61 bottoms containing hole 612 that sets to the concave, should compress spring 62 with ccontaining, this jacking block 61 more is concaved with an elongated slot 611 that is parallel to these lockhole 3 center lines, be complementary with a restrictions 31, and slide onto via 5 along this restrictions 31, this restrictions 31 can be a steady pin, and an end of this steady pin is located on the hole wall of lockhole 3, and the other end penetrates in the elongated slot 611;
One projection 32 is located at the bottom in the lockhole 3, for placing this compression spring 62;
One steel ball 8 places in first space 41 versatilely;
One lock core structure 7 is arranged in this core groove 4, and it comprises a body 71 and a shifting block 72, this body 71 is clogged in second space 42, this shifting block 72 convexedly stretches in first space 41, and rotates together with key, makes this shifting block 72 turn to a lockset position of coupler from a locked position of coupler; And
One torsionspring 74, one end are fixed on this body 71, and the other end is fixed on this shifting block 72, wherein, when this shifting block 72 when a locked position of coupler goes to a lockset position of coupler, this torsionspring 74 savings one twisting resistance makes this shifting block 72 involution automatically to locked position of coupler.
As shown in Figure 3, this locked mechanism comprises that more a pad 73 pads place on the body 71 of this lock core structure 7, these pad 73 central authorities can wear a trepanning 75, shifting block 72 for lock core structure 7 passes through, this pad 73 not only can separate out first space 41 and second space 42 particularly, and this steel ball 8 is moved in first space 41 smooth-goingly.
Consult Fig. 4,5, for locked mechanism is in the figure of a snap close state, second end 12 of this block piece 1 inserts in these lockholes 3, and makes this liftout attachment 6 move down, the compression spring 62 savings one top power of this liftout attachment 6; 72 of this shifting blocks are in locked position of coupler, and this steel ball 8 is pushed against in this via 5, make these steel ball 8 parts by this via 5, and embed in the recess 13 of this block piece 1 second end 12, make second end 12 of this block piece 1 can't recess this lockhole 3.
Consult Fig. 6,7, otherwise locked mechanism of the present utility model is in a unlocking condition.This shifting block 72 is gone to lockset position of coupler by key, and this torsionspring 74 is put aside a twisting resistance because of the rotation of shifting block 72.The more important thing is that the pushing and pressing that this shifting block 72 is removed this steel ball 8 make steel ball 8 can recess the recess 13 of block piece 1 second end 12; At this moment, 62 on the compression spring of this liftout attachment 6 disengages top power, second end 12 of block piece 1 is ejected lockhole 3, make the jacking block 61 of this liftout attachment 6 be subject to this restrictions 31 and only can be moved to via 5 places, make this steel ball 8 be subjected to stopping of this jacking block 61 and can't protrudingly be exposed in the lockhole 3 along the inwall of lockhole 3; In addition, the twisting resistance of this torsionspring 74 can't make shifting block 72 involutions to locked position of coupler, and make this shifting block 72 only can push against this steel ball 8 to jacking block 61 because of this steel ball 8 is subjected to stopping of this jacking block 61.
So, second end, 12 these lockholes 3 of insertion when block piece 1, and when making this jacking block 61 leave this via 5 with moving down, 61 releasing stopping of this jacking block to this steel ball 8, make the twisting resistance of this torsionspring 74 must be, and this steel ball 8 is pushed against in this via 5, and embed in the recess 13 of block piece 1 second end 12 for this shifting block 72 involution automatically to locked position of coupler, make second end 12 can't recess lockhole 3, make this locked mechanism be in the snap close state.
In sum, more than only be a preferred embodiment of the present utility model, can not limit practical range of the present utility model with this, the equalization of doing according to the utility model changes and modifies generally, all should be encompassed in the scope of this claim.
