Abstract

Claims (14)

1 . A quick-lock connector used for a counterpart connector ( 100 ), the quick-lock connector ( 10 ) comprising:

a connector body ( 1 );

a rotary sleeve ( 2 ), rotatably disposed around the connector body ( 1 ), and the rotary sleeve ( 2 ) comprising a latching structure ( 21 ) capable of latching the counterpart connector ( 100 ); and

a clockwork spring ( 3 ), nested between the connector body ( 1 ) and the rotary sleeve ( 2 ) for elastically supporting, which is an elastic spiral strip ( 31 ) coiled from inner a first end fixed to the connector body ( 1 ) to outer a second end fixed to the rotary sleeve ( 2 ) on a same plane;

wherein multiple engaging bumps ( 5 ) extend from one of an outer periphery of the connector body ( 1 ) and an inner periphery of the rotary sleeve ( 2 ), and an annular bump ( 6 ) circumferentially extends on another one of the outer periphery of the connector body ( 1 ) and the inner periphery of the rotary sleeve ( 2 ), the annular bump ( 6 ) comprises multiple elongated trenches ( 61 ) extending circumferentially and multiple inserting openings ( 62 ) disposed at a side thereof and respectively communicating with the elongated trenches ( 61 ), the engaging bumps ( 5 ) are allowed to move into the elongated trenches ( 61 ) through the inserting openings ( 62 ) respectively so as to be received in the elongated trenches ( 61 ) respectively and slidable along a circumferential direction of the annular bump ( 6 );

wherein one engaging bump ( 5 ) comprises a first slope ( 51 ), a ramp block ( 63 ) protrudes from an inner bottom surface at one end of one elongated trench ( 61 ) adjacent to one inserting opening ( 62 ), the ramp block ( 63 ) comprises a height thereof decreasing toward the one inserting opening ( 62 ) so as to define a second slope ( 631 );

wherein when the one engaging bump ( 5 ) is in the one inserting opening ( 62 ), the first slope ( 51 ) and the second slope ( 631 ) abut against with each other to guide the one engaging bump ( 5 ) to slide through the ramp block ( 63 ) first and then enter the one elongated trench ( 61 );

wherein when the one engaging bump ( 5 ) is located in the one elongated trench ( 61 ), the ramp block ( 63 ) stops between the one elongated trench ( 61 ) and the one inserting opening ( 62 ), so the one engaging bump ( 5 ) and the ramp block ( 63 ) stop each other to use the ramp block ( 63 ) to limit the one engaging bump ( 5 ) to be located in the one elongated trench ( 61 ).

2 . The quick-lock connector of claim 1 , wherein an annular groove ( 4 ) is defined on one of the outer periphery of the connector body ( 1 ) and the inner periphery of the rotary sleeve ( 2 ), the outer periphery of the connector body ( 1 ) is disposed with a first trough ( 12 ), the inner periphery of the rotary sleeve ( 2 ) is disposed with a second trough ( 22 ), and the elastic spiral strip ( 31 ) is embedded in the annular groove ( 4 ) to have the first end bent to form a first folding end ( 32 ) embedded into the first trough ( 12 ) and-the second end bent to form a second folding end ( 33 ) embedded into the second trough ( 22 ).

3 . The quick-lock connector of claim 1 , wherein the engaging bumps ( 5 ) are four in number and the elongated trenches ( 61 ) are four in number, the four engaging bumps ( 5 ) and the four elongated trenches ( 61 ) are respectively arranged along the outer periphery of the connector body ( 1 ) and the inner periphery of the rotary sleeve ( 2 ) at intervals.

4 . The quick-lock connector of claim 1 , wherein the connector body ( 1 ) comprises a connecting portion ( 11 ) at an end thereof, and the multiple engaging bumps ( 5 ) and the annular bump ( 6 ) are arranged between the connecting portion ( 11 ) and the clockwork spring ( 3 ).

5 . The quick-lock connector of claim 1 , wherein the counterpart connector ( 100 ) comprises multiple L-shaped engaging grooves ( 101 ) and multiple stopping blocks ( 102 ) disposed corresponding to the L-shaped engaging grooves ( 101 ) respectively, the latching structure ( 21 ) comprises multiple latches ( 211 ) extending from an inner periphery of the rotary sleeve ( 2 ), the latches ( 211 ) are allowed to move into the L-shaped engaging grooves ( 101 ) respectively and stopped by the stopping blocks ( 102 ) respectively.

6 . The quick-lock connector of claim 5 , wherein the clockwork spring ( 3 ) returns the rotary sleeve ( 2 ) to a position to stop the latches ( 211 ) by the stopping blocks ( 102 ) respectively.

7 . The quick-lock connector of claim 5 , wherein the L-shaped engaging grooves ( 101 ) are four in number, the stopping blocks ( 102 ) are four in number and the latches ( 211 ) are four in number, the four L-shaped engaging grooves ( 101 ) and the four stopping blocks ( 102 ) are arranged along a circumferential direction of the counterpart connector ( 100 ) at intervals, and the four latches ( 211 ) are arranged along an inner periphery of the rotary sleeve ( 2 ) at intervals.
