The specific embodiment

Below in conjunction with accompanying drawing and concrete preferred embodiment, the utility model is elaborated, so that advantage of the present utility model and feature can be easier to be understood by those skilled in the art, these embodiment are only illustrative objects, are not intended to scope of the present utility model to limit.

Refer to Fig. 1, paying-off fixture of the present utility model comprises tool left end cap 1, tool bobbin 2 and tool right end cap 4, described tool left end cap 1 and tool right end cap 4 lay respectively at described tool bobbin 2 two ends and with described vertical connection of tool bobbin 2, described tool left end cap 1 is discoid with tool right end cap 4, the outer rim of described tool right end cap 4 is provided with runner 5, described runner 5 is connected by bearing 9 with the outer rim of described tool right end cap 4, described runner 5 is coaxial with described tool right end cap 4, on the outer side plane 16 of described runner 5 and described tool right end cap 4, be provided with and control between described runner 5 and described tool right end cap 4 rotary locking device 100 in relative rotation, on described runner 5, be provided with a conical through-hole 13.

Preferably, as shown in Fig. 1, Fig. 3, Fig. 4 and Fig. 5, described rotary locking device 100 comprise with described runner 5 column 6 connected vertically, with active connecting rod 7 and at least two latch 8 that are connected in the outer end of described column 6, described latch 8 is arranged at respectively on the outer side plane 16 of described runner 5 and described tool right end cap 4, has the groove 14 matching with described connecting rod 7 on described latch 8.Between the outer end of described column 6 and described connecting rod 7, preferably by bearing pin or movable balls, being connected, can be also other movable connection modes, and connecting rod 7 can be rotated around bearing pin.The other end of depressing connecting rod 7 enters in the groove 14 of the latch 8 on tool right end cap 4 this end, because groove 14 has certain length, equals by connecting 7, runner 5 and tool right end cap 4 to be locked together, and runner 5 just can not relatively rotate with tool right end cap 4.When the other end of connecting rod 7 being pressed into runner 5 when the groove 14 of latch 8 is with it interior, now runner 5, with tool right end cap 4 in non-lockup state, can relatively rotate between runner 5 and tool right end cap 4.

Preferably, as shown in Figure 2, described conical through-hole 13 is less than the bore dia in the relative side plane one end of the outer side plane 16 with described runner 5 at the bore dia of outer side plane 16 one end of described runner 5.

Preferably, on the inwall of the large end of diameter of described conical through-hole 13, be provided with circular arc chamfering 15.

Further, paying-off fixture of the present utility model is when unwrapping wire, and the conical through-hole 13 first enamel wire exit 10 being passed runner 5 from tool right end cap inside region 11, arrives tool right end cap exterior lateral area 12, then guides to target ground.On large end inwall due to conical through-hole 13, be provided with circular arc chamfering 15, at enamel wire exit 10, from the large end of conical through-hole 13 during through conical through-hole 13, circular arc chamfering 15 makes the enamel wire 2 can be not injured.

Further, the protruding end of connecting rod 7 is pressed in the groove 14 of runner 5 oneself latch 8 with it, now runner 5, with tool right end cap 4 in non-lockup state, can relatively rotate between runner 5 and tool right end cap 4.By enamel wire 3 ceaselessly when tool bobbin 2 is pulled out, enamel wire 3 relatively rotates with tool bobbin 2, owing to now also relatively rotating between runner 5 and tool right end cap 4, be that runner 5 can keep relative static with enamel wire 3, make enamel wire 3 all the time in stabilized conditions, can not tangle winding, can not tie a knot.

Be different from prior art, paying-off fixture of the present utility model can be realized the continous-stable unwrapping wire of enamel wire, there will not be the abnormalities such as winding, knotting or random line of enamel wire, and unwrapping wire is effective.

The foregoing is only embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model specification sheets and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
