The present invention relates to a bobbin structure for winding wires with improved mobility. Specifically, the bobbin structure is provided with a moving member to ensure mobility in transporting the bobbin structure, and the moving member is rotated through a simple operation. The purpose is to provide a bobbin structure for winding wires that can improve mobility by allowing users to easily transport the bobbin structure by facilitating movement on and off the ground with a moving member.

For a more detailed description, the present invention will be described below with reference to the accompanying drawings, and multiple drawings may be referred to simultaneously to explain one technical feature and the components constituting the invention.

It would be natural to understand that the scope is not limited.

Additionally, in the following description, multiple drawings will be simultaneously referred to and described in order to explain components constituting one technical feature or invention.

Looking at the drawings attached as a description of the present invention, FIG. 1 shows an example of the schematic shape of a bobbin structure for winding wire with improved mobility, and FIG. 2 shows an example of the shape of the spool and rotation axis on which the wire is wound. An example of the shape of the plate is shown in Figure 3, and an example of the schematic shape of the fixing part is shown in Figure 4. In addition, Figure 5 shows examples of the shapes of the plate, fixed part, and moving member, Figures 6 and 7 show examples of rotation of the moving member hinged to the fixed part, and Figure 8 shows another embodiment of the present invention. An example of rotation of the moving member according to is shown, and Figures 9 and 10 show an example of length extension through the combination of a plurality of spools and a rotation shaft.

Referring to FIG. 1, which shows an example of the schematic shape of a bobbin structure for winding wires with improved mobility according to an embodiment of the present invention, the bobbin structure for winding wires with improved mobility in the present invention largely consists of a spool 110. , it may include a plate 120, a rotating shaft 130, a fixing part 140, a support member 150, and a moving member 160.

First, the spool 110 is a wire wound on the outer surface, and is formed in a cylindrical shape as shown in Figures 1 and 2. A first hole 111 is formed inside along the longitudinal direction, and a first hole 111 is formed on the outer surface. A screw thread 112 may be formed.

At this time, the screw thread 112 formed on the outer surface of the spool 110 serves as a guide to ensure that the wire is wound according to the rotation direction of the screw thread 112 when the wire is wound around the spool 110. It is desirable to understand that it is formed so as to be wound without being tangled with each other.

Meanwhile, the plate 120 is coupled to both ends of the spool 110 to fix the spool 110, and is provided as a pair, and is formed in the shape of a disk having a diameter larger than the diameter of the spool 110. , a second hole of the same size as the first hole 111 formed in the spool 110 may be formed in the center.

At this time, by making the diameter of the plate 120 larger than the diameter of the spool 110, the effect of preventing the wire wound around the spool 110 from being separated can be achieved.

Additionally, the plate 120 can be combined with the spool 110 to form a single bobbin structure. In this case, as an embodiment of the present invention, a fitting coupling method using a coupling protrusion and a coupling groove may be used.

Specifically, as shown in FIG. 3, the plate 120 may be formed with a first coupling protrusion 122 for coupling to the spool 110.

The first coupling protrusion 122 protrudes and extends outward from a region of the inner surface of the plate 120, and is preferably formed in the shape of a polyhedron.

Meanwhile, the second hole is formed inside the first coupling protrusion 122, and the second hole is a circular shape that penetrates from the outer surface of the plate 120 to the first coupling protrusion 122. It is preferable to understand that it is a hole.

Meanwhile, as shown in FIGS. 1 and 2, the spool 110 has a first coupling groove 113 at one area at both ends corresponding to the shape of the first coupling protrusion 122 formed on the plate 120. It may be formed in a concave shape.

Therefore, the plate 120 on which the first coupling protrusion 122 is formed is fitted into each of the first coupling grooves 113 formed at both ends of the spool 110 and assembled to form a bobbin structure. It becomes possible.

Meanwhile, in one embodiment of the present invention, the plate 120 is fixed by fitting the first coupling protrusion 122 into the first coupling groove 113 formed on the spool 110, but is not required. It may also be possible to separate according to , and the present invention is not limited thereto.

In addition, as an embodiment of the present invention, the first coupling protrusion 122 is formed as a polyhedron so that the spool 110 and the plate 120 are unwound at the same time as the wire wound around the spool 110 is unwound. It would be desirable to understand that this is to prevent the spool 110 and the plate 120 from being rotated in different directions or separated from each other due to rotational force generated while rotating.

Meanwhile, in Figure 3, an embodiment in which the shape of the first coupling protrusion 122 formed on the plate 120 is a pentagonal polyhedron is shown limitedly, but the first coupling protrusion 122 is formed on the spool 110. If it is coupled and fixed and does not rotate separately, but can rotate simultaneously with the spool 110, it is natural that it can be modified and changed into various polyhedral shapes, including tetrahedrons, pentahedrons, and hexahedrons. And the present invention is not limited thereto.

Continuing the description with reference to FIGS. 1 and 2 again, the rotation axis 130 is formed in a rod shape, and is formed in the first hole 111 and the plate 120 formed in the spool 110. It may be understood that the bobbin structure, which is inserted into the second hole 121 and formed by combining the spool 110 and the plate 120, serves as an axis during rotation.

That is, the first hole 111 formed in the spool 110 as the plate 120 is coupled to both ends of the spool 110, and the second hole formed in the plate 120 ( 121) are combined to form one through hole, and it is preferable to understand that the rotation axis 130 is inserted into the through holes 111 and 121.

In addition, as an embodiment of the present invention, the bobbin structure formed by combining the spool 110 and the plate 120 is coupled to a rod-shaped rotation axis 130, and rotates about the rotation axis 130 to form the bobbin. It can be understood that the wire can be wound around the outer surface of the spool 110, which constitutes the structure, or the wound wire can be unwound and used.

Meanwhile, as shown in FIG. 1, it is preferable that fixing parts 140 are coupled to both ends of the rotating shaft 130 to fix the rotating shaft 130.

At this time, the rotation axis 130 has a polyhedral third coupling protrusion 131 extending from one end, and a third coupling groove 132 corresponding to the shape of the third coupling protrusion 131 is concavely formed at the other end. It can be formed into a shape.

Therefore, the third coupling protrusion 131 formed at one end of the rotation shaft 130 and the third coupling groove 132 formed at the other end, that is, the fixing portion 140 at both ends of the rotation shaft 130. is combined to fix the rotation axis 130.

Specifically, the fixing part 140 is understood to fix both ends of the rotating shaft 130 inserted through the first hole 111 and the second hole 121 formed in the bobbin structure. It would be desirable.

As described above, by fixing both ends of the rotating shaft 130 with the fixing part 140, the bobbin structure coupled to the rotating shaft 130 can be prevented from being separated from the rotating shaft 130. This has the effect of enabling rotation along the rotation axis 130.

Meanwhile, as an embodiment of the present invention, the fixing part 140 may include a first fixing part 141 and a second fixing part 143, as shown in FIG. 4.

The first fixing part 141 is coupled to the third coupling protrusion 131 formed on the rotation shaft 130 by forming a fourth coupling groove 142 of a shape corresponding to the third coupling protrusion 131. The third coupling groove ( 132), the first fixing part 141 and the second fixing part 143 are coupled to both ends of the rotating shaft 130, so that the rotating shaft 130 can be fixed.

In addition, as an embodiment of the present invention, the third coupling protrusion 131 and the third coupling groove 132 are formed in a polyhedron by rotation of the bobbin structure coupled to the rotation axis 130. It may be understood that this is to prevent the rotation shaft 130 from being easily separated from the fixing part 140 while preventing the rotation shaft 130 from rotating.

Meanwhile, if the third coupling protrusion 131 and the third coupling groove 132 are coupled to the fixing part 140 and have a shape that prevents them from rotating separately in a fixed state, they can be formed in various shapes including a tetrahedron, pentahedron, and hexahedron. It is natural that the shape of a polyhedron can be modified and implemented as many times as desired, but the present invention is not limited thereto.

Next, a support member 150, a wheel 162, and a handle 163 are formed in one area of the fixing part 140 to support the bobbin structure by separating it from the ground, so as to move the bobbin structure. Members 160 may be coupled.

Referring to FIGS. 4 and 6, the support member 150 is formed in a trapezoidal shape and is coupled to one area of the fixing part 140, and its height is formed to be larger than the radius of the plate 120. , It can be understood that the bobbin structure is supported by being separated from the ground.

Meanwhile, in one embodiment of the present invention, the support member 150, which performs the function of supporting the bobbin structure by separating it from the ground, is provided by the fixing part 140 to support the bobbin structure from falling or moving. It would be desirable to fix and combine it in one area.

In addition, as another embodiment of the present invention, the lower part of the support member 150, that is, the part directly in contact with the ground, is formed to have a certain thickness or more to stably support the bobbin structure and increase contact force with the ground. It would be desirable for the thickness to be adjustable, but the present invention is not limited thereto.

Meanwhile, although not explicitly shown in the attached drawing, the lower part of the support member 150 is made of natural rubber (NR), butadiene rubber (BR), styrene/butadiene rubber (SBR), and nitrile rubber to increase grip with the ground. (NBR) may further include a support portion (not shown) using a mixture of at least one rubber, and in addition to the above-mentioned rubber, any material that can increase grip can be used, and the present invention provides this. Not limited.

Next, referring to FIGS. 4 and 5 where the shape of the moving member 160 can be seen, the moving member 160 in the present invention consists of a frame 161, a wheel 162, and a handle 163. Consists of.

The frame 161 constitutes the basic shape of the moving member 160 and may be formed in a trapezoidal shape according to an embodiment of the present invention.

Meanwhile, a wheel 162 may be coupled to an area at the bottom of the frame 161, and the wheel 162 is coupled to an area at the bottom of the frame 161 to move the bobbin structure on the ground. Understanding is desirable.

Meanwhile, as a preferred embodiment of the present invention, as shown in FIGS. 4 and 5, a plurality of wheels 162 are provided at both ends of the lower part of the frame 161, so that the bobbin structure can be easily lifted from the ground by being level with the ground. It is desirable to keep it moving.

In addition, the wheel 162 is preferably coupled to the bottom of the frame 161 so that it can rotate 360 degrees, and the bobbin structure can be easily moved in the direction desired by the user through the wheel 162 that can rotate 360 degrees. This is possible, and can have the effect of improving mobility when moving the bobbin structure on the ground.

Meanwhile, although not explicitly shown in the attached drawings, in the present invention, the wheel 162 may be provided with a brake (not shown).

At this time, the brake is a component that controls the movement of the wheel 162, and when moving the bobbin structure on the ground, it controls the movement of the wheel 162 by operating the brake as necessary to keep the bobbin structure from the ground. It can have a fixing effect.

Next, the handle 163 is formed at the bottom of the frame 161 and can perform the function of lifting and moving the bobbin structure.

Specifically, the handle 163 is formed at the bottom of the frame 161 and connects the left and right sides of the frame 161, thereby dispersing the external force transmitted to the frame 161, By preventing the frame 161 from being twisted or deformed, it can be effective in maintaining the shape of the frame 161.

Meanwhile, although not explicitly shown in the attached drawings, as another embodiment of the present invention, a guide groove (not shown) is formed in one area of the handle 163 in a shape that allows the user to rest his or her fingers easily so that the user can easily hold it with his or her hand. ) may be formed.

When the user holds the handle 163 and moves the bobbin structure through the guide groove, the handle 163 can be held more stably and is formed into a shape where the finger can rest, thereby improving the grip. It can be effective.

Additionally, the handle 163 may be made of a material that improves traction so that it does not slip when touched by the user's hand, but the present invention is not limited thereto.

Meanwhile, as shown in FIGS. 5 to 7, the moving member 160 is hinged at an upper end of the frame 161 to one area of the fixing part 140, so that the moving member 160 moves relative to the fixing part 140. It can be rotated up and down.

As an embodiment of the present invention, when the bobbin structure needs to be moved on the ground, the wheel 162 is brought into contact with the ground, and when the bobbin structure needs to be lifted and moved, the hinge is used as shown in FIG. 7. It is preferable to rotate the coupled moving member 160 so that the handle 163 is located at the upper end of the bobbin structure.

That is, as shown in FIG. 6, when the handle 163 is located at the upper end of the bobbin structure, it is easy for the user to move while holding the handle 163, which has the effect of improving mobility. will be.

In addition, when the moving member 160 is rotated to lift and move the bobbin structure so that the handle 163 is located at the upper end of the bobbin structure, the support member 150 is attached to the moving member 160. Instead of the formed wheel 162, it would be possible to support the bobbin structure away from the ground.

Meanwhile, after lifting and moving the bobbin structure, when it is necessary to move it again on the ground, rotate the moving member 160 so that the handle 163 is located at the upper end of the bobbin structure and then lift the handle 163. By holding and moving the bobbin structure and then rotating the moving member 160 so that the wheel 162 touches the ground, the bobbin structure can be easily moved on the ground.

On the other hand, as another embodiment of the present invention, the frame 161 of the moving member 160 may be formed in an A shape as shown in FIG. 8, and one of the fixing parts 140 In the method of coupling the moving member 160 to the region, the outer surface of the plate 120 is fixed by rotatably 360 degrees at the upper end of the frame 161 of the moving member 160, rather than by hinge coupling. Accordingly, the moving member 160 may be able to rotate 360 degrees.

Meanwhile, the shape of the frame 161 can be changed to any shape as long as it can be rotated by fixing one area at the top and the wheel 162 can be coupled to one area at the bottom, according to the present invention. is not limited to this.

As such, the bobbin structure of the present invention with improved mobility includes the spool 110, the plate 120, the rotation shaft 130, the fixing part 140, the support member 150, and the moving member 160. Since each component can be combined and separated, even if one of the components is damaged, the damaged component can be easily separated and replaced.

Meanwhile, the spool 110 described above can be extended in length in the axial direction by assembling one or more spools 110 connected to each other.

Specifically, the spool 110 has a second coupling protrusion 115 of a predetermined thickness extending along the outer peripheral surface of the first coupling groove 113 formed at one end, as shown in FIGS. 1 and 2. , A second coupling groove 114 corresponding to the shape of the second coupling protrusion 115 may be formed in a concave shape along the outer peripheral surface of the first coupling groove 113 formed at the other end.

At this time, the second coupling protrusion 115 is assembled by fitting into the second coupling groove 114 formed on the other spool 110 located adjacent to the spool 110. It can be understood that the two spools 110 are assembled so that the length can be extended.

Additionally, the preset thickness of the second coupling protrusion 115 may be changed depending on the diameter of the spool 110 and the size of the first coupling groove 113, etc., but the present invention is not limited thereto.

Meanwhile, as an embodiment of the present invention, referring to FIGS. 9 to 10 showing an example in which a plurality of spools (110a, 110b) are combined to extend the length, the second spool (110a, 110b) formed on the spool (110a, 110b) The coupling protrusion 115 and the second coupling groove 114 are such that, when two or more spools 110a and 110b are coupled in the axial direction, the second coupling protrusion 115 formed at one end of one spool 110a is adjacent to each other. By entering and engaging the second coupling groove 114 formed on the other spool 110b, which is positioned in a similar manner, the fastening force between two or more spools 110a and 110b is increased and at the same time, when the spools 110a and 110b rotate, This can be understood as preventing them from being separated from each other.

In addition, after two or more spools (110a, 110b) are combined in the axial direction to extend the length, the first coupling grooves (113) formed at both ends of the extended spools (110a, 110b) are connected to each other. It may be understood that the first coupling protrusion 122 of the plate 120 is inserted and coupled to form a bobbin structure with an extended length of the spool.

Therefore, as described above, a plurality of spools are combined to extend the length, thereby achieving the effect of winding a large amount of wire.

Meanwhile, according to an embodiment of the present invention, when a plurality of spools are combined to extend the length, the rotation shaft 130, which is inserted into the first hole 111 of the spool and serves as an axis, is also combined with each other to extend the length. It is desirable to do so.

Specifically, as shown in FIGS. 9 and 10, a third coupling protrusion 131 formed on the other rotation axis 130b located adjacent to the third coupling groove 132 of one rotation axis 130a is fitted. It can be understood that the length can be extended by combining and assembling a plurality of rotation axes 130a and 130b.
