Referring to Fig. 1, a kind of auto-tensioning central spindle, comprising: beam barrel 100, slide assemblies 200 and tension assembly 300 need
Illustrate, the beam barrel 100 is for being clamped the slide assemblies and fixed tension assembly；The slide assemblies 200 be used for
Tension assembly abuts, so that tension assembly realizes the operation opened or shunk；After the tension assembly 300 opens, it may be implemented
Coiling can then separate central spindle and coiled wire rod when deflated.
Referring to Fig. 2, the first limiting slot 110 is offered on one end of the beam barrel 100, the other end of the beam barrel 100
On offer the second limiting slot 120；It should be noted that first limiting slot 110 is used to be clamped the first circlip, so that
Upper end sliding block is limited on beam barrel.Similarly, second limiting slot 120 is for being clamped the second circlip, so that lower end
Sliding block is limited on beam barrel.
Referring again to Fig. 1, the slide assemblies 200 include upper end sliding block 210, lower end sliding block 220, the first circlip
230 and second circlip 240, for first circlip 230 in first limiting slot 110, the upper end sliding block 210 is sliding
Dynamic to be placed on one end of the beam barrel 100, second circlip 240 is in second limiting slot 120, the lower end
The sliding of portion's sliding block 220 is placed on the other end of the beam barrel 100.It should be noted that upper end sliding block 210 and lower end are sliding
Block 220 facilitates the effect for carrying out coiling and taking out coiled wire rod for driving each axis block to open or shrink；Institute
The first circlip 230 is stated for blocking upper end sliding block 210；Second circlip 240 does not allow for blocking lower end sliding block 220
It is detached from beam barrel 100 in sliding process.
Referring to Fig. 1, the tension assembly 300 includes multiple axis blocks 310 and multiple locating parts 320, each axis block 310
Upper to offer limiting through hole 311 respectively, each locating part 320 wears a limiting through hole 311, and each limit
Part 320 is respectively arranged on the beam barrel 100, the first side of each axis block 310 respectively with 210 phase of upper end sliding block
It abuts, the second side of each axis block 310 is abutted against with the lower end sliding block 220 respectively.It should be noted that the axis
Block 310 can carry out coiling and take-up operation, and the locating part 320 is used to axis block 310 being limited to the beam barrel 100.
In this way, when needing to carry out coiling, then it is upper end sliding block and lower end sliding block is sliding to beam barrel center
It is dynamic, so that each axis block is mobile to the direction far from beam barrel center, so that the outer diameter of central spindle becomes larger, when increasing coiling
The size of coiling radius；After the completion of coiling, when needing to take out central spindle from coiled wire rod, then by upper end sliding block under
End sliding block is slided to the direction far from beam barrel center, so that each axis block is mobile to beam barrel center, so that axis
The outer diameter of core becomes smaller, and facilitates taking-up central spindle, easily separates central spindle and coiled wire rod.
It should be noted that offering first through hole on the upper end sliding block, the beam barrel wears the first through hole,
And the upper end sliding block is abutted against with first circlip.In this way, by setting first through hole, it can be by upper end sliding block
It is nested on beam barrel.
It should be noted that offering the second through-hole on the lower end sliding block, the beam barrel wears second through-hole,
And the lower end sliding block is abutted against with second circlip.In this way, by the second through-hole of setting, it can be by lower end sliding block
It is nested on beam barrel.
It should be noted that the locating part is screw.Multiple screw holes 130 are offered on the beam barrel 100, it is each described
Locating part is bolted in a screw hole.In this way, each locating part can be fixed on beam barrel.
It should be noted that the aperture of the limiting through hole is greater than the diameter of the locating part.So, it is ensured that upper
When end sliding block and lower end sliding block are slided to beam barrel center, i.e., so that each axis block will not be limited when being displaced outwardly
Through-hole hinders, and facilitates and open each axis block；And when axis block is shunk, axis block will not be stopped and moved
It is dynamic.
In the present embodiment, the upper end sliding block is frustum cone structure.The lower end sliding block is frustum cone structure.The axis
It is provided with the upper sliding surface being bonded with the upper end sliding block on block, is provided on the axis block and is bonded with the lower end sliding block
Lower slider face.In this way, the side of upper end sliding block can be with the upper sliding surface phase of the axis block when carrying out flaring operation
It abuts, while the side of lower end sliding block can be abutted against with the axis block lower slider face, to work as upper end sliding block and lower end
When sliding block is slided to beam barrel center, since the upper sliding surface of axis block and lower slider face receive the effect of power, each axis can be made
Block is displaced outwardly, so that the diameter of axle of central spindle becomes larger, is facilitated and is carried out take-up and winding operation；When upper end sliding block and lower end
When sliding is not by the effect of external force, then make each axis block mobile to beam barrel center, so that central spindle is outer
Diameter becomes smaller, and facilitates taking-up central spindle, easily separates central spindle and coiled wire rod.
In the present embodiment, there are four the axis block settings, interval is respectively arranged between four axis blocks.It needs
It is bright, by four axis blocks of setting, the outer diameter of central spindle can be made to become larger more effectively, so that take-up is more efficient,
Facilitate carry out coiling, reduces labour, further increase production efficiency.
The utility model compared with the prior art the advantages of and have the beneficial effect that:
The utility model is a kind of auto-tensioning central spindle, when needing to carry out coiling, then by upper end sliding block under
End sliding block is slided to beam barrel center, so that each axis block is mobile to the direction far from beam barrel center, so that axis
The outer diameter of core becomes larger, and increases the size of coiling radius when coiling；After the completion of coiling, need central spindle from coiled wire rod
When taking-up, then upper end sliding block and lower end sliding block are slided to the direction far from beam barrel center, so that each axis block is into beam barrel
Heart position is mobile, so that the outer diameter of central spindle becomes smaller, facilitates taking-up central spindle, easily by central spindle and coiled wire rod point
From reduction labor intensity improves production efficiency.
Embodiment described above only expresses the several embodiments of the utility model, and description is more specific and detailed
Carefully, but it should not be understood as limiting the scope of the patent of the utility model.It should be pointed out that for the general of this field
For logical technical staff, without departing from the concept of the premise utility, various modifications and improvements can be made, these are all
Belong to the protection scope of the utility model.Therefore, the scope of protection shall be subject to the appended claims for the utility model patent.
