Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, be locking Anti-extrusion device of the present utility model, comprise overcoat 1, inner sleeve 2, limit element 1, limit element 24, latch 5, fixed block 6 and resisting part 7.Inner sleeve 2 is set on the main shaft 11 of winder, main shaft 11 be axially arranged with draw-in groove 12, inner sleeve 2 be axially arranged with the holding hole 9 corresponding with draw-in groove 12 position.Axial one end away from holding hole 9 of inner sleeve 2 is provided with holding cavity 8, and limit element 1 elasticity is contained in holding cavity 8.In present embodiment, limit element 1 comprises elastic element 31 and steel ball 32, elastic element 31 and steel ball 32 are all contained in holding cavity 8, one end of elastic element 31 is fixedly connected with the bottom of holding cavity 8, its the other end is fixedly connected with steel ball 32, and when elastic element 31 is in free state, steel ball 32 part protrudes from holding cavity 8.Overcoat 1 is set in inner sleeve 2, and limit element 1 is for supporting the left end of overcoat 1, thus restriction overcoat 1 is moved to the left in inner sleeve 2.In inner sleeve 2, between holding cavity 8 and holding hole 9, position is provided with chute 10, latch 5 is fixedly mounted on overcoat 1, the afterbody of latch 5 protrudes from the inner side of overcoat 1, the ultimate range moved left and right relative to inner sleeve 2 for limiting overcoat 1 that cooperatively interacts of latch 5 and chute 10.Resisting part 7 is socketed on main shaft 11, is positioned at the side of inner sleeve 2 near holding hole 9, and inner sleeve 2 and resisting part 7 support, and fixed block 6 is fixedly connected with resisting part 7 with inner sleeve 2 respectively, and operationally, resisting part 7 is for supporting I-beam wheel.
Fixed block 6 is roughly triangular in shape, and the drift angle of fixed block 6 is fixedly connected with resisting part 7, and the limit that fixed block 6 is relative with described drift angle is fixedly connected with inner sleeve 2, because of the feature of triangle stability, and fixed block 6 triangular shaped more firm, long service life.
The both ends of the surface that overcoat 1 contacts with inner sleeve 2 are that chamfering is arranged, and in the sliding process of overcoat 1 in inner sleeve 2, two chamferings of overcoat 1 constantly can extrude limit element 1 and limit element 24, and this kind of chamfering arranges and make slip more smooth and easy.
Latch 5 comprises screw 51 and nut 52, and nut 52 is screwed onto on screw 51, and the afterbody of screw 51 protrudes from the inner side of overcoat 1.
Elastic element 31 is metal spring, and metal spring is conventional machinery component, wide material sources.Be appreciated that elastic element 31 can also be elastic caoutchouc, also can realize the function compressed and reset.
Limit element 24 is steel ball.A part for described steel ball is embedded in draw-in groove 12, and another part is embedded in holding hole 9, and limit element 24 is for limiting the movement of inner sleeve 2 on main shaft 11.
During use, the first high order end of sliding outer cover 1 to inner sleeve 2, now, latch 5 is in the high order end of chute 10, and limit element 1 is pressed into holding cavity 8 by overcoat 1, and holding hole 9 is exposed, and limit element 24 can be taken out or put into arbitrarily in holding hole 9.Then inner sleeve 2 is set on main shaft 11, now holding hole 9 is corresponding with draw-in groove 12 position on main shaft 11, limit element 24 is put into from holding hole 9, a part for limit element 24 is positioned at holding hole 9, another part is positioned at draw-in groove 12, limit element 24 limits the movement of inner sleeve 2, makes inner sleeve 2 relative main 11 static, prevents inner sleeve 2 from deviating from from main shaft 11.Further, move right past relative to inner sleeve 2 for overcoat 1, latch 5 is turned right and is slided in chute 10, and when latch 5 moves to the right-hand member of chute 10, overcoat 1 stops mobile.Now overcoat 1 covers holding hole 9, thus prevents limit element 24 from deviating from from holding hole 9.Holding cavity 8 is exposed simultaneously, and steel ball 32 ejects under the effect of elastic element 31 elastic force from holding cavity 8, thus supports the left end of overcoat 1.Steel ball 32 limit overcoat 1 toward moving left, latch 5 limits overcoat 1 toward moving right, both cooperations make overcoat 1, and inner sleeve 2 is static relatively.
I-beam wheel is in rotation process, and inner sleeve 2 gives resisting part 7 one resist force, thus effectively supports I-beam wheel.When needing to change I-beam wheel, described locking Anti-extrusion device is needed to take off from main shaft 11, only need by overcoat 1 toward moving left, steel ball 32 is pressed into holding cavity 8 by overcoat 1, holding hole 9 is exposed, take out limit element 24, inner sleeve 2 is taken off from main shaft 11, easily can take off described locking Anti-extrusion device.
To one skilled in the art, according to technological scheme described above and design, other various corresponding change and deformation can be made, and all these change and deformation all should belong within the protection domain that the utility model requires.
