Technical Field

The invention relates to the technical field of coil frameworks, in particular to a coil framework.

Background

Coils generally refer to a winding of wire in the shape of a loop, the most common coil applications being: motors, inductors, transformers, loop antennas, and the like.

The coil needs the skeleton to support when winding, but, has some coil to use together without the skeleton when using, and current coil skeleton integrated into one piece often has the inconvenience when taking off the coil after winding.

Aiming at the problems, the coil framework is designed.

Disclosure of Invention

The present invention is directed to a coil bobbin to solve the above-mentioned problems.

In order to solve the technical problems, the invention adopts the following technical scheme:

a coil framework comprises a first arc-shaped plate and a second arc-shaped plate, wherein the first arc-shaped plate is connected with a first screw, a first nut is in threaded connection with the first screw, a second nut is connected with the first nut through a pull rod, a second screw is in threaded connection with the second nut, and thread sections of the first screw and the second screw are arranged in opposite directions;

the second arc is connected with the movable rod, the sleeve has been cup jointed in the movable rod activity, threaded connection has first locking screw in the screw hole of seting up on the sleeve, and first locking screw is located the inside one end of sleeve and offsets with the movable rod, two the one end that the sleeve is close to each other, two the one end that the second screw rod is close to each other is connected with same center pin.

Preferably, the both ends of second arc all are connected with the attachment strap, and the attachment strap is located the inside of first arc, and the attachment strap offsets with first arc, and help second arc is fixed a position fast.

Preferably, the movable ends of the first screw and the second screw are connected with spheres to limit the moving distance of the first screw cap and the second screw cap.

Preferably, the locating grooves are formed in the two ends of the central shaft, and therefore the device can be conveniently clamped and located by the external clamping device.

Preferably, T-shaped grooves are formed in the first arc-shaped plate and the second arc-shaped plate, an inner connecting plate is inserted into the T-shaped grooves, a first supporting plate or a second supporting plate is connected onto the inner connecting plate, second locking screws are connected into threaded holes formed in the first arc-shaped plate and the second arc-shaped plate in a threaded mode, and one ends, located inside the T-shaped grooves, of the second locking screws are abutted to the inner connecting plate.

Preferably, the movable end of the first supporting plate is arc-shaped, and the movable end of the second supporting plate is conical.

The invention has the beneficial effects that:

when the wound coil needs to be taken down, the whole length of the movable rod and the sleeve is shortened to drive the second arc-shaped plate to move, the length between the first screw rod and the second screw rod is shortened to drive the first arc-shaped plate to move, so that a gap is generated between the coil and the circular framework, and the coil is convenient to take down;

the combined structure of the first screw, the first nut, the pull rod, the second nut and the second screw enables the moving distance of the first arc-shaped plate to be more accurate, and the combined structure of the movable rod, the sleeve and the first locking screw enables the second arc-shaped plate to be fast in place after the first arc-shaped plate is accurately in place, so that the installation time is saved.
