The disclosure relates to a connector structure, particularly to a quick-lock connector.
A connection of male and female heads of a related-art quick-lock connector has a convex structure and a concave structure disposed on rotary sleeves which are engaged with each other and has a spiral spring is used for returning the rotary sleeve, so that the rotary sleeve is pulled by the spiral spring and locked at a position where the convex structure is engaged with the concave structure.
However, the spiral spring of the above-mentioned quick-lock connector is arranged and installed along the circumferential direction of the rotary sleeve, so the spiral spring must be bent to form an arc shape in advance, and a guide mechanism should be additionally used for assembling the spiral spring on the rotary sleeve. However, it can easily detach from the rotary sleeve if a slightly improper force is applied to the spiral spring, this leads to the inconvenience of assembling to operators and a waste of labor.
In view of this, the inventors have devoted themselves to the above-mentioned prior art, researched intensively and cooperated with the application of science to try to solve the above-mentioned problems. Finally, the invention which is reasonable and effective to overcome the above drawbacks is provided.
The disclosure provides a quick-lock connector, which has a clockwork spring nested between the connector body and the rotary sleeve for elastically supporting so that it is easy for assembling and labor saving.
In an embodiment of the disclosure, the disclosure provides a quick-lock connector used for a counterpart connector, the quick-lock connector includes a connector body, a rotary sleeve and a clockwork spring. The rotary sleeve is rotatably disposed around the connector body and includes a latching structure which can be engaged with the counterpart connector. The clockwork spring nested between the connector body and the rotary sleeve for elastically supporting.
Accordingly, the clockwork spring is an elastic spiral strip and therefore suitable for being installed in an annular space, so that the clockwork spring may be directly nested between the connector body and the rotary sleeve without being bent and deformed and an additional guiding mechanism. Thus, when assembling the quick-lock connector, the clockwork spring will not separate from the rotary sleeve due to an elastic return force caused by an improper force exerted on the clockwork spring, so that the assembling of the quick-lock connector is easy and labor saving.
The technical contents of this disclosure will become apparent with the detailed description of embodiments accompanied with the illustration of related drawings as follows. It is intended that the embodiments and drawings disclosed herein are to be considered illustrative rather than restrictive.

In addition, the L-shaped engaging grooves 101 is four, the stopping blocks 102 is four and the latches 211 is four. 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 regular intervals. That is, the four L-shaped engaging grooves 101 and the four stopping blocks 102 are evenly disposed at the upper, lower, left and right sides of the counterpart connector 100. The four latches 211 are arranged along the inner periphery of the rotary sleeve 2 at regular intervals. That is, the four latches 211 are evenly disposed at the upper, lower, left and right sides of the rotary sleeve 2, so that the connection of the rotary sleeve 2 and the counterpart connector 100 can be firmer and have an even force.
Further, one of the outer periphery of the connector body 1 and the inner periphery of the rotary sleeve 2 is disposed with an annular groove 4. 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. In the embodiment, the annular groove 4 is formed on the outer periphery of the connector body 1, but not limited to this, the annular groove 4 may also be formed on the inner periphery of the rotary sleeve 2.
Also, multiple engaging bumps 5 are protruded from one of the outer periphery of the connector body 1 and the inner periphery of the rotary sleeve 2, and another one of the outer periphery of the connector body 1 and the inner periphery of the rotary sleeve 2 has an annular bump 6 extended along a circumferential direction thereof. The annular bump 6 has multiple elongated trenches 61 extended along the circumferential direction and multiple inserting openings 62 at a side of the annular bump 6. The inserting openings 62 are communicated to the elongated trenches 61 respectively. The engaging bumps 5 may be moved into the elongated trenches 61 respectively through the inserting openings 62 respectively so as to be received in the elongated trenches 61 respectively and slidably along a circumferential direction of the annular bump 6.
In addition, one of the engaging bumps 5 has a first slope 51. A ramp block 63 is protruded from an inner bottom surface at one end of the elongated trenches 61 which is adjacent to the inserting opening 62. The ramp block 63 has a height thereof decreasing toward the inserting opening 62 so as to defined a second slope 631. When the engaging bump 5 is in the inserting opening 62, the first slope 51 and the second slope 631 can abut against each other to guide the engaging bump 5 to slide through the ramp block 63 first and then enter the elongated trench 61. When the engaging bump 5 is located in the elongated trench 61, the ramp block 63 stops between the elongated trench 61 and the inserting opening 62, so the engaging bump 5 and the ramp block 63 can stop each other to use the ramp block 63 to limit the engaging bump 5 to be located in the elongated trench 61.
In the embodiment, the multiple engaging bumps 5 are protruded from the inner periphery of the rotary sleeve 2, and the annular bump 6 is protruded from the outer periphery of the connector body 1, but not limited to this, the multiple engaging bumps 5 may also be protruded from the outer periphery of the connector body 1, and the annular bump 6 may also be protruded from the inner periphery of the rotary sleeve 2.
Also, in the embodiment, 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 arranged along the outer periphery of the connector body 1 and the inner periphery of the rotary sleeve 2 at regular intervals. That is, the four engaging bumps 5 and the four elongated trenches 61 are evenly disposed at the upper, lower, left and right sides of the connector body 1 and the rotary sleeve 2, so that the connection of the rotary sleeve 2 and the connector body 1 can be firmer and have an even force.

In detail, the elastic spiral strip 31 is embedded in the annular groove 4 and one end thereof is bent with a first folding end 32 embedded into the first trough 12 and the other end is bent with a second folding end 33 embedded into the second trough 22.
The multiple engaging bumps 5 and the annular bump 6 are arranged between the connecting portion 11 and the clockwork spring 3. The clockwork spring 3 drives the rotary sleeve 2 to move to a position of each latch 211 which is stopped by each stopping block 102 to return.

While this disclosure has been described by means of specific embodiments, numerous modifications and variations could be made thereto by those skilled in the art without departing from the scope and spirit of this disclosure set forth in the claims.
