Description

Manual high-efficient doubling ware

Technical Field

The invention relates to a manual high-efficiency doubling winder, and belongs to the field of electric power.

Background

The wires are often required to be connected in power construction and transformation. The common lead is a polyvinyl chloride insulation copper core wire, the connection modes of the lead comprise twisted connection, compression connection, welding and the like, wherein the twisted connection is the most common and the safest connection mode, but the connection needs to peel off and combine two ends, the lead is peeled off by using a vice in most prior art, the combined wire after peeling off is also performed by using the vice in most prior art, the working efficiency is low, the combined wire connection is not tight, and the hand is easy to hurt. At present, a doubling device is required to be matched with an electric drill for use, but the electric drill is required to perform operations such as punching, and the doubling device is different in specification and needs to be selected and used according to the wire diameter, so that a drill bit needs to be frequently replaced, and the efficiency is low.

Disclosure of Invention

According to the defects in the prior art, the technical problems to be solved by the invention are as follows: the utility model provides a manual high-efficient doubling winder of manual operation, the doubling is compact, and the contact is good, need not the electric drill and assists, and is efficient, with low costs.

The manual high-efficiency doubling winder comprises an outer cover, wherein the outer cover is in a flat barrel shape, the bottom surface of the outer cover is a downwards sunken conical surface, and a through hole is formed in the center of the bottom of the outer cover; comprises an inner cover, the inner cover is in the shape of an inverted flat drum, the outer edge of the inner cover is matched with the inner edge of the outer cover, and a plurality of notches are arranged on the edge of the inner cover.

The stripped electric wires extend into the outer cover from the through hole, then the inner cover is pressed in the outer cover, the electric wires are clamped in different notches (preferably opposite notches), the outer cover is fixed, and the electric wires can be twisted into strands by rotating the inner cover.

The center of the upper part of the inner cover is provided with a threaded hole, the threaded hole is matched with an adjusting screw, the lower end of the adjusting screw is coaxially fixed with a cone, the cone is matched in the inner cover, the conical surface of the cone is parallel to the bottom surface of the outer cover, and the cone tip of the cone is positioned on the axis of the through hole. The distance between the conical surface of the cone and the inner bottom surface of the outer cover is adjusted by rotating the adjusting screw rod so as to adapt to wires with different diameters. Meanwhile, the conical surface of the cone can separate the wires, and the larger the angle for separating the wires is, the tighter the wires are wound.

The tail end of the adjusting screw rod is fixed with a twisting handle, so that the adjusting screw rod can be conveniently rotated.

Two opposite handles are hinged to the outer end face of the lower portion of the outer cover, mounting seats are fixed to opposite faces of the handles respectively, rollers are mounted on the mounting seats in an axially-mounted mode, and the two rollers correspond to each other in position. The handle is gripped after threading for the gyro wheel presss from both sides tight electric wire, and tight gyro wheel can provide the resistance for the electric wire is backed down, avoids the electric wire to back down too fast, still does not influence the removal of electric wire simultaneously, makes the winding of electric wire compacter.

The rollers are gear-shaped, the rollers are made of rubber-like materials, the stranded wires are twisted, and when two teeth on each roller are in contact with the wires, the wires need to be retracted by a large retracting force to rotate the rollers; deformation can take place when the gyro wheel of gluing the material compresses tightly on the electric wire, and the area of contact of increase gyro wheel and electric wire increases frictional force, can prevent to skid between electric wire and the gyro wheel, further improves the winding degree of compactness of electric wire.

Set up the screw thread on the through-hole inner wall, through screw thread fit threading pipe in the through-hole, can select the threading pipe of different internal diameters according to the quantity of line footpath and line. Therefore, the electric wire can be more tightly wound, and the winding compactness of the electric wire is improved.

The bayonet is evenly distributed on the edge of the twisting handle, the clamping rod is hinged on the upper end face of the inner cover and matched with the bayonet, the rotating handle is vertically fixed at the top end of the clamping rod, and when the clamping rod is clamped into the bayonet, the rotating handle is parallel to the end face of the inner cover. Therefore, on one hand, the cone is fixed, the cone is prevented from rotating due to the friction force of the electric wire, on the other hand, the rotating handle is rotated by hands to rotate the inner cover, and the operation is convenient.

The conical surface of the cone and the inner end surface of the outer cover are smooth, so that the friction force between the electric wire and the cone and between the electric wire and the outer cover can be reduced.

The edge of the lower section of the inner cover is provided with a chamfer, and the chamfer is matched with the inner end face of the outer cover, so that the gap between the inner cover and the outer cover is reduced, and the electric wire is prevented from being clamped tightly.

The working principle and the process are as follows:

during operation, the electric wire of having shelled the line inserts the threading pipe, separates the electric wire around the back, then adjusts the cone according to the line footpath, and in the electric wire card goes into corresponding breach, then clenches the handle on the one hand, and the inner cup is rotated on the other hand, and bare-handed just can twist into the thigh with the electric wire.

Compared with the prior art, the invention has the beneficial effects that:

according to the manual high-efficiency doubling winder, an electric wire stripped is inserted into the threading pipe, the electric wire is separated after being wound, then the cone is adjusted according to the wire diameter, the electric wire is clamped into the corresponding notch, then the handle is held by one hand, the inner cover is rotated by the other hand, and the electric wire can be twisted into a strand by bare hand. The doubling is compact, the contact is good, the assistance of an electric drill is not needed, the efficiency is high, and the cost is low.
