Abstract
The utility model discloses one to pull strings device, comprise base, shield, bearing, collar, upper bolt, lower bolt, nut, unwrapping wire bar and hexagonal swivel nut, base is provided with axially extending bore, axially extending bore perisporium is provided with ring-shaped step and annular slot, bearing and axially extending bore interference fit, bearing is close on ring-shaped step, collar is stuck in annular slot, hexagonal swivel nut is by the inner ring upper end of lower bolt presses at bearing, shield is enclosed within the hexagonal swivel nut above axially extending bore, hexagonal swivel nut is provided with a radial circular hole, unwrapping wire bar right part is inserted in radial circular hole, and by upper bolt and lower bolt-locking, upper bolt top is connected with a conductor rod by nut, unwrapping wire bar left end and conductor rod upper end are all connected with a loop.The utility model has the advantage of: when using enamel wire, wire spool without the need to rotation and deployable around the enamel wire on wire spool, thus can reduce pulling force suffered by enamel wire greatly, and then can effectively avoid enamel wire impaired.
Description
Technical field
The utility model relates to a kind of actinobacillus device, particularly a kind of device of pulling strings that can will launch gradually around the enamel wire on wire spool.
Background technology
Enamel wire is all deposited usually on wire spool, when enamel wire need be used, the wire spool being wound with enamel wire is enclosed within a rotating shaft by staff, then pullling enamel wire one end with equipment makes enamel wire drive wire spool to rotate, thus reach the object launched and use enamel wire, but because the wire spool being wound with enamel wire is heavier, therefore when pullling enamel wire, wire spool is driven to rotate in order to enable enamel wire, pulling force suffered by enamel wire will be larger, and this very easily can cause enamel wire impaired, particularly when enamel wire wire diameter is less, enamel wire damage situations more easily occurs.
Utility model content
The technical problems to be solved in the utility model is, there is provided a kind of when using enamel wire, wire spool without the need to rotation and deployable around the enamel wire on wire spool, thus can reduce pulling force suffered by enamel wire greatly, and then the device of pulling strings can effectively avoiding enamel wire impaired.
For solving the problems of the technologies described above, the utility model provides and a kind ofly adopts the device of pulling strings of following structure: comprise base, shield, bearing, collar, upper bolt, lower bolt, nut, unwrapping wire bar and hexagonal swivel nut, base is provided with axially extending bore, axially extending bore perisporium is provided with a ring-shaped step and an annular slot, the outer ring of bearing and axially extending bore inwall interference fit, and the lower end, outer ring of bearing is close on ring-shaped step, collar to be positioned at above bearing and to be stuck in annular slot, hexagonal swivel nut bottom is positioned at axially extending bore, and by the inner ring upper end of lower bolt presses at bearing, shield is enclosed within the hexagonal swivel nut above axially extending bore, hexagonal swivel nut is provided with a radial circular hole, unwrapping wire bar right part is inserted in radial circular hole, and by upper bolt and lower bolt-locking, upper bolt top is connected with a conductor rod by nut, unwrapping wire bar left end and conductor rod upper end are all connected with a loop.
Device of pulling strings described in the utility model, wherein, unwrapping wire bar left part is provided with a downward bending.
Device of pulling strings described in the utility model, wherein, base bottom is provided with positioning boss.
After adopting said structure, the utility model has the following advantages: the utility model pull strings device use time, base only need be placed on the upper end of wire spool by staff, then by enamel wire one end from bottom to up successively through being connected to the loop of unwrapping wire bar left end and be connected to the loop of conductor rod upper end, now, after enamel wire is pullled, enamel wire will drive unwrapping wire bar respect thereto to rotate, and along with the rotation of unwrapping wire bar, will Automatic-expanding gradually around the enamel wire on wire spool.As from the foregoing, pull strings after device at use the utility model, wire spool without the need to rotations and deployable around the enamel wire on wire spool, thus makes the pulling force suffered by enamel wire greatly be reduced, and then effectively prevent the impaired situation generation of enamel wire.
The utility model pull strings the downward bending that is arranged on unwrapping wire bar left part in device not only can make around the enamel wire on wire spool launch more smooth and easy, and the pulling force suffered by enamel wire can also be reduced further.
The utility model effect being arranged on the positioning boss of base bottom in device of pulling strings is: positioning boss can be inserted in the axis hole of wire spool, thus can effectively prevent the utility model pull strings device in use relative to wire spool produce move, be convenient to the utility model pull strings device locate.
