Description

Wire winding adjust apparatus

The present invention relates to a wire take-up control device, and more particularly, to a wire take-up control device with improved product assembly convenience and productivity.

In general, shoes such as sports shoes are provided with shoelaces that can be tightened so as to be in close contact with the size of the wearer's feet, and by pulling and tightening these shoelaces, the adhesion between the shoes and the feet is increased to enable comfortable walking.

At this time, the conventional shoelace is connected in a zigzag form to the upper side of the shoe, so that the wearer must directly tie or untie it and adjust it, and there is a problem that such manipulation is difficult for children or the elderly. Accordingly, in some cases, devices having a structure capable of quickly and conveniently tightening and loosening shoelaces by rotating in a dial form have been disclosed.

On the other hand, Figure 1 is an exploded perspective view showing a device for tightening a shoelace in the related art.

As shown in FIG. 1, the conventional device 10 for tightening the shoelace is rotated together by combining the intermediate member 53 and the winding member 55 when rotating the rotating cover 51. At this time, while the wire (L) replacing the shoelace is wound around the winding member 55, the shoe may be tightened according to the size of the foot. Here, since the mating constraining portion 53z formed on the intermediate member 53 is bitten and constrained by the ratchet gear 57c of the housing 57, the wire L is released due to the winding member 55 being rotated in the reverse direction. Can be prevented.

In addition, when the rotation cover 51 is pulled upward, the intermediate member 53 is moved upward together with the rotation cover 51. Through this, when the coupling state between the intermediate member 53 and the winding member 55 is released and the winding member 55 is freely rotated, the wire L can be pulled and released.

On the other hand, the wire (L) is wound on the outer circumferential surface of the winding member 55 when the rotation cover 51 is rotated in a state where both ends are bound to the winding member 55. At this time, both ends of the wire (L) may be forcibly fitted into a binding hole formed in the winding member 55, sandwiched between a divided winding member, or bound through a separate fixing part.

Here, when the both ends of the wire (L) are double-folded and forcibly fitted through the binding holes formed in the winding member (55), the size of the binding hole is more than twice the cross-sectional area of the wire (L), There was a problem that they could not be bound together. In addition, since the size of the binding hole must be differently manufactured according to the diameter of the wire L, there is a problem in that productivity is lowered.

In addition, when the winding member is dividedly manufactured or bonded through a separate fixing part, the shape of the mold becomes complicated, and the assembly man-hours and assembly time increase, thereby reducing productivity and economy.

The paper can be firmly bonded by increasing the pressing force and the frictional area between them.

Third, through the guide protrusion protruding toward the front side, the inlet direction is the same, and the first binding hole and the third binding hole penetrated adjacently are partitioned, so that the end of the wire is continuously formed on the front side of each binding hole. Since it is accurately guided and moved to the transit/bonding space, accuracy and convenience can be remarkably improved when assembling the product.

Fourth, as the fastening guide mark part is indicated by numbers or arrows on the outer surface of the reel part corresponding to each fastening hole, it is possible to intuitively check not only the penetrating position of each fastening hole, but also the fastening sequence, even for beginners with insufficient work experience. Since the wire can be easily bound, productivity can be remarkably improved.

As shown in Figures 2 to 3, the wire winding adjustment device 100 according to an embodiment of the present invention includes a housing unit 130, a rotation operation means, and a reel unit 140.

In detail, the wire winding adjustment device 100 is fixed to a fastening object such as a shoe, and a wire L disposed to pass through the circumference or one surface of the fastening target during rotation operation is wound inside to reduce the size of the fastening target. It is provided to adjust.

Here, the housing unit 130 is coupled to the upper side of the coupling base unit 160 fixed to the fastening object, and a ratchet type gear 133 is formed along the inner circumferential surface. In addition, the reel unit 140 is accommodated in the housing unit 130, and the rotation operation means and the reel unit 140 are configured to be selectively interlocked and rotated so that the wire L is rotated to the reel unit. It is wound on the outer peripheral surface of (140). In addition, a guide protrusion 138 in which an inlet hole 138a is formed may be protruded in the housing unit 130 so that the end Lb of the wire L is drawn from the outside toward the reel unit 140.

At this time, the rotation operation means is rotated around the driving protrusion 115 provided in the central portion, and is provided including a rotation cover 110 and a gear portion 120. In detail, the rotation cover 110 is rotatably coupled to the upper end of the housing unit 130 by an external force, and mutually engaging and engaging surfaces of the rotation cover 110 and each side of the housing unit 130 are coupled to each other.

It is desirable to understand. In addition, it is preferable that the front side, the front side, or the other side to be described later be understood as a direction corresponding to a direction in which the wire L is drawn into the fastening groove 144. In addition, it is preferable that the rear, rear side or one side be understood as a direction corresponding to a direction in which the wire L is drawn outward from the fastening groove 144.

As shown in FIGS. 4A to 5, the reel part 140 includes a winding body part 141 and a flange part 142. Here, the winding body portion 141 is provided in a cylindrical shape, and the flange portion 142 protrudes radially outward along the upper and lower edges of the outer circumferential surface of the winding body portion 141. And, the wire (L) is wound in the wire winding groove (142d) formed between the inner surface facing the flange portion 142 when rotating the wire winding adjustment device 100.

Here, it is preferable that the winding body part 141 is provided including a fastening groove 144 and a wire fastening part 145.

In detail, the gear coupling portion (G2) protrudes upward on the upper surface side of the winding body portion 141, and the receiving groove 143 in which the end of the driving protrusion 115 is accommodated in the central portion of the gear coupling portion (G2). Is formed. In addition, the fastening groove 144 is recessed in front of the lower surface side of the winding body 141, and is formed as a via/binding space in which the end Lb of the wire L is moved or bound through mutual pressure. . In addition, the wire binding portion 145 is formed as a solid body portion at the rear side of the fastening groove portion 144, and a plurality of binding holes are formed through the front and rear directions.

Here, it is preferable that the fastening groove 144 is formed in one of a continuous linear shape and a forward convex shape in which one side inner wall 144b formed by depression is formed. That is, the fastening groove 144 may be formed as a semicircular groove in a cross section. On the other hand, in one embodiment of the present invention, the one side inner wall (144b) is described and shown as an example that is formed in a continuous straight line.

In front of the one inner wall 144b, a pressure communication part 144a disposed via a part La of the wire L bound to the reel part 140 through a series of steps to be described later is provided with the fastening groove 144 ) Is preferably formed continuously in correspondence with both directions of.

At this time, the means that the pressing communication part 144a is continuously formed means that the plurality of the binding holes are formed to cross the front side of the first binding hole 145a and the second binding hole 145b, which will be described later, as a whole. It is desirable to understand that. In addition, it is preferable to understand that the via/binding space is the other side of the fastening groove 144 corresponding to the front side of the pressing communication part 144a.

That is, it is preferable to understand that the fastening groove 144 covers the pressure communication part 144a and the gas oil/binding space. In detail, it is preferable to understand that the pressure communication part 144a is a part through which a part La of the wire L passes through a series of processes to be described later. And, the via / binding space is a via space that is moved so that the end (Lb) of the wire (L) through the first binding hole (145a) or withdrawn through the second binding hole (145b) and will be described later. It is re-entered through the third binding hole (145c), but it is preferable to understand that it encompasses a binding space in which the end (Lb) of the wire (L) pressed to the portion (La) of the wire (L) is accommodated. As described above, in the present invention, the portion to which the wire (L) is bound is received in the fastening groove portion 144 which is recessed on one side of the reel portion 140 and there is substantially no portion protruding to the outside. This can prevent damage to the product in advance.

On the other hand, it is preferable that the wire binding portion 145 includes a plurality of binding holes which penetrate from the one inner wall 144b to one side of the outer peripheral surface of the winding body 141. Here, the plurality of the binding holes are adjacent to the bottom surface of the pressure communication part (144a) so that a portion (La) of the wire (L) is passed through, but the first binding holes (145a) and the It includes a second binding hole (145b). And, the end (Lb) of the wire (L) re-entered toward the fastening groove (144) is a portion of the wire (L) passing through the first fastening hole (145a) and the second fastening hole (145b) It includes the third binding hole (145c) disposed between the first binding hole (145a) and the second binding hole (145b) so as to be pressed and fixed to (La).

In this case, the third binding hole (145c) is preferably formed to be spaced downward from the bottom surface of the pressure communication portion (144a) toward the lower surface side of the reel portion (140). Accordingly, the third binding hole 145c forms a pressing step of a predetermined height corresponding to a space spaced apart from the first binding hole 145a and the second binding hole 145b in the vertical direction. Accordingly, a portion (La) of the wire (L) passing through the first binding hole (145a) and the second binding hole (145b) through the third binding hole (145c) the fastening groove (144) The pressure of pressing the end (Lb) of the wire (L) drawn into the bottom surface side of the pressure communication portion (144a) increases in response to the pressure level difference.

In addition, as the third binding hole (145c) is formed stepped from the first binding hole (145a) and the second binding hole (145b), the end (Lb) of the wire (L) is the wire (L) It is bent and bound while being pressed toward the bottom surface of the pressing communication part (144a) by a portion (La) of. Through this, even if there is no separate fixing member or pressing member, the wire L can be maintained in a state that is firmly bound to the reel unit 140.

Moreover, when the one side inner wall 144b is formed in one of a continuous linear shape and a forward convex shape as described above, the pressing step is more than the conventional one in which each binding hole is formed to be stepped diagonally or the portion where each binding hole is formed is concave. Increases. At the same time, a portion (La) of the wire (L) is wrapped along the outer circumference of the end (Lb) of the wire (L) may increase the friction area in contact with each other. Accordingly, a fixed state may be stably maintained while a portion La of the wire L presses the end Lb of the wire L more firmly.

At this time, it is preferable that a protrusion 149 on which the end portion Lb of the wire L is aligned and supported is protruded stepwise on the pressure communication part 144a.

In detail, the protrusion 149 is formed as a stepped protruding from the bottom surface of the pressing communication part 144a corresponding to the third binding hole 145c, Through this, the outer surfaces of the pressure communication part 144 and the protrusion part 149 are formed to be stepped at a predetermined protrusion height. In this case, the height of the protrusion 149 is preferably set to a point between the bottom surface of the pressing communication part 144a and the bottom end of the third fastening hole 145c. Accordingly, the bottom surface of the pressing communication part 144a, the protrusion 149, and the third fastening hole 145c may be stepped in multiple stages. In addition, the protrusion 149 may be protruded at an interval corresponding to a range of 30 to 70% of the interval between the bottom surface of the pressing communication unit 144a and the bottom surface side end of the third fastening hole 145c. In addition, a seating bone 149a on which the end Lb of the wire L is seated may be formed.

Through this, the end (Lb) of the wire (L) re-entered into the inner side of the fastening groove (144) through the third fastening hole (145c) is stepped downward than the bottom surface of the pressure communication part (144a). As it is disposed, the pressure step further increases. Through this, a force for pressing the end portion Lb of the wire L by a portion La of the wire L may be further increased. At the same time, since the protrusion 149 also forms a predetermined step with the third fastening hole 145c, the end Lb of the wire L is bent while being pressed against a portion La of the wire L. Can be maintained and bonded more firmly.

Moreover, while the end (Lb) of the wire (L) is seated on the seating bone (149a) and the binding position is fixed, the end (Lb) of the wire (L) and a portion (La) of the wire (L) are mutually The area to be contacted by pressure may be relatively increased. Through this, since the area where the end (Lb) of the wire (L) rubs against not only the portion (La) of the wire (L) but also the seating bone (149a) is increased, it can be fixed more firmly, so that assembly stability is remarkable. It can be improved. In addition, as the seating bone 149a is formed, both sides thereof are formed as stepped jaws, so that the position where the end portion Lb of the wire L is inserted is automatically aligned, so that the binding operation is easier.

In addition, it is preferable that a guide protrusion 144e protruding forward from the one inner wall 144b is formed between the first binding hole 145a and the third binding hole 145c. In addition, it is preferable that the first fastening hole 145a has a gradient guide surface 147a inclined toward the outer edge toward the front of the fastening groove 144. That is, the gradient guide surface 147a is formed to be inclined from the pressing communication part 144a toward the outer edge of the other inner wall 144c, which is a surface opposite to the one inner wall 144b.

In detail, between the first and third binding holes 145a and 145c having the same lead-in direction of the wire L and formed adjacent to each other is partitioned by the guide protrusion 144e. That is, when the end (Lb) of the wire (L) is drawn into the inner side of the fastening groove 144 through the first fastening hole (145a), the movement path is formed to face continuously on the front side thereof It can be accurately guided to the space, that is, the gradient guide surface 147a. In addition, even when the end (Lb) of the wire (L) is re-entered into the fastening groove (144) through the third fastening hole (145c), the moving path is easily accommodated in the via / fastening space on the front side thereof. Can be.

Accordingly, a plurality of the binding holes (145a, 145b, 145c) are formed to be spaced apart at a predetermined interval in the limited area of the inner wall (144b) of the fastening groove (144), so that the first binding hole (145a) is obliquely penetrated. Even if it is, since the retracting direction is guided regardless of the angle at which the end Lb of the wire L is retracted through the guide protrusion 144e, convenience and accuracy in assembling the product can be further improved.

On the other hand, the gradient guide surface 147a is preferably formed in the front and rear directions on the front side of the fastening groove 144 corresponding to the first fastening hole 145a. Through this, the end (Lb) of the wire (L) introduced through the first fastening hole (145a) slides along the slope guide surface (147a) and can be naturally moved to the lower surface side of the reel part (140). have.

In addition, an auxiliary gradient guide surface 147b inclined toward the second fastening hole 145b may be formed on the front side of the fastening groove 144 corresponding to the first fastening hole 145b. In detail, the auxiliary gradient guide surface 147b may be formed to be inclined from the other inner wall 144c to the bottom surface of the pressing communication part 144a corresponding to the second fastening hole 145b. That is, the present invention is accurate and easy by simply sliding the end (Lb) of the wire (L) along the gradient guide surface (147a) and the auxiliary gradient guide surface (147b) when binding the wire (L). Can penetrate.

At this time, although not shown in the drawing, a pair of fitting partition walls may further protrude along the longitudinal inner end of the gradient guide surface 147a and the longitudinal outer end of the auxiliary gradient guide surface 147b. The pair of fitting partition walls may be provided with inner surfaces facing each other, and an end portion Lb of the wire L may be fitted and fixed to the inner side facing each other. In addition, as a portion (La) of the wire (L) passing through the first binding hole (145a) and the second binding hole (145b) is disposed in a state that spans the pair of fitting partition walls, the third binding hole The end (Lb) of the wire (L) re-introduced through (145c) may be easily disposed between a portion (La) of the wire (L) and the bottom surface of the pressure communication part (144a).

Meanwhile, the fastening groove 144 is preferably divided into both sides by a central partition wall 146 extending orthogonal to the one side inner wall 144b and crossing the central portion. In addition, the first to the third binding hole (145a) to the third binding hole (145c) is configured as a set, it is preferable that each is provided in a pair symmetrically left and right with respect to the central partition wall (146).

Here, it is preferable that both ends of the wire (L) are respectively bound to a plurality of binding holes formed symmetrically on both sides of the wire binding portion 145, but the central portion is disposed so as to pass through the circumference or one surface of the fastening object. Of course, in some cases, each end of the wire (L) is bound to a plurality of the fastening holes formed symmetrically on both sides of the wire fastening part 145, but each other end separates the circumference or one side of the fastening object. It can also be arranged to pass through symmetrically.

At this time, the present invention is directly coupled so that the driving protrusion (115 in FIG. 3) protrudes downward from the rotation cover (110 in FIG. 3), but only the gear part (120 in FIG. 3) can be lifted and rotated. It is extended only to the length that can be achieved. Accordingly, the winding body part 141 may be formed in a structure in which the receiving groove 143 and the fastening groove 144 are not communicated and are divided up and down through the transverse partition wall 140h.

That is, the reel part 140 applied to the present invention may be provided in a structure in which a separate through part is not formed in the central part. Accordingly, the fastening groove 144 may be formed entirely on the lower surface of the winding body 141, and a space in which the wire L is bound while passing through the plurality of fastening holes may be sufficiently secured.

Moreover, since the fastening groove 144 may be formed to correspond to the cross-sectional area of the winding body 141, a pair of the wire fastening parts 145 may be provided symmetrically to the left and right as described above. Through this, the conventional inconvenience of rotating the reel 140 to assemble both ends or each end of the wire L can be fundamentally eliminated.

That is, unlike the conventional reel portion in which the pair of wire binding portions 145 are provided with rotational symmetry due to the through portion formed in the center, the present invention is provided in a left-right symmetric manner, so that the wire ( L) can be easily bound.

In addition, the space in which the gradient guide surface 147a, the auxiliary gradient guide surface 147b, and the end Lb of the wire L are fixed is substantially at the front side of each of the binding holes 145a, 145b, and 145c. Is formed on the same line. Therefore, as long as the end (Lb) of the wire (L) passes through each of the binding holes (145a, 145b, 145c), it can be naturally moved to a desirable position for movement and binding. Through this, convenience in assembling the product is improved, and since the time required for binding the wire L is shortened, productivity may be remarkably improved.

Moreover, the pulling directions to bind both ends or each end of the wire L are substantially the same. Accordingly, it is possible to simultaneously grasp and pull the pair of wire binding portions 145 in a state in which both ends or ends of each of the wires L are passed. Accordingly, the both ends or each end of the wire L to each of the wire binding portions 145 can be simultaneously bound and fixed only by pulling once, so assembly convenience is remarkably improved and the assembly time is remarkably shortened, thereby improving productivity. Can be.

In addition, as the fastening groove 144 is recessed in a semicircular shape on the front side of the winding body 141, a semicircular solid body portion may be formed on the rear side thereof. Accordingly, even if a plurality of the binding holes 145a, 145b, and 145c are penetrated in a plurality in both directions, the durability of the reel unit 140 may be remarkably improved. Through this, even if the wire L passing through each of the binding holes 145a, 145b, and 145c is strongly pulled so as to be rigidly bound, it can be prevented from being damaged by an external force. In addition, as the contact area between the wire L and the inner circumferential surfaces of each of the binding holes 145a, 145b, and 145c increases, the fixing force due to friction may be further improved.

On the other hand, a fastening guide marking part (142c) is formed on the outer surface of the reel part 140 corresponding to the first fastening hole (145a) to the third fastening hole (145c) to guide the binding step of the wire (L). This is desirable.

In detail, the fastening guide marking part 142c may include a number corresponding to each of the binding holes and a mark such as an arrow guiding a direction through which the wire L passes through each of the binding holes. Moreover, each mark of the fastening guide mark part 142c is preferably displayed on the outer surface of the reel part 140 corresponding to the position of each of the fastening holes, preferably on the lower surface side where the fastening groove part 144 is formed.

Through this, even if the outer ends of each of the binding holes 145a, 145b, and 145c are covered by the flange portion 142, the through position can be intuitively and accurately recognized. In addition, if the wire (L) is passed through the number indicated on the fastening guide mark portion (142c) or the direction of the arrow, it can be accurately bound via the fastening position. Therefore, even for a beginner who lacks assembly experience, the wire L can be easily bound along the fastening guide marking part 142c, and thus productivity can be remarkably improved.

The fastening guide marking part 142c may be formed to be integrally displayed on the reel part 140 by embossing or intaglio, and may be printed or manufactured as a sticker and attached thereto.

On the other hand, FIGS. 6A and 6D are partial projections of a process in which a wire is bound to a reel portion applied to a wire winding adjustment device according to an embodiment of the present invention, as viewed from the lower side. At this time, it is preferable to understand that the part marked in bold on the drawing is for distinguishing the binding hole/groove part from the solid body.

As shown in FIGS. 6A to 6D, the process of binding the wire L to the reel 140 is as follows. At this time, the wire (L) is preferably understood that both ends are bound to the wire binding portion 145 formed symmetrically left and right by the central partition wall (146).

6A, the end Lb of the wire L is introduced into the fastening groove 144 through the first fastening hole 145a. At this time, since the guide protrusion 144e protrudes between the first binding hole 145a and the third binding hole 145c, the end of the wire L drawn through the first binding hole 145a (Lb) may be accurately guided to the gradient guide surface 147a. And, when the end (Lb) of the wire (L) slides to the front side along the gradient guide surface (147a) and is exposed to the outside of the fastening groove (144), the operator is exposed to the end (Lb) of the wire (L). ) Can be easily gripped.

6B, the end (Lb) of the wire (L) moved along the gradient guide surface (147a) is drawn out to one side of the outer peripheral surface of the winding body part (141) through the second binding hole (145b). However, a portion (La) of the wire (L) is disposed in a state that spans the lower surface side of the winding body (141). This means that the end (Lb) of the wire (L) re-entered into the fastening groove (144) through the third fastening hole (145c) is a portion (La) of the wire (L) and the pressure communication part (144a). It is intended to be placed between the bottom of ).

Here, the end (Lb) of the wire (L) slides along the auxiliary gradient guide surface (147b) formed to be inclined in the front side of the second binding hole (145b), and the second binding hole (145b) It can be easily withdrawn through.

6C, the end (Lb) of the wire (L) drawn out through the second fastening hole (145b) is re-entered into the fastening groove (144) through the third fastening hole (145c), and the It is disposed between a portion (La) of the wire (L) and the bottom surface of the pressure communication portion (144a). At this time, by the guide protrusion 144e, the end Lb of the wire L may be prevented from being erroneously introduced into the gradient guide surface 147a.

Here, it is preferable that the second binding hole 145b and the third binding hole 145c are separated by a partition wall 145d having at least one edge portion 145e on the outer surface side.

In detail, the wire (L) passes through the first binding hole (145a), the second binding hole (145b), and the third binding hole (145c) sequentially while the second binding hole (145b) and the It is bound to surround the partition wall (145d) separating the three binding holes (145c). At this time, the partition wall 145d is rapidly bent while the wire L surrounding the partition wall 145d is supported by the edge portion 145e as at least one edge portion 145e is formed on the outer surface side. Part is formed. Through this, the wire (L) surrounding the partition wall (145e) can be more firmly bound because it prevents loosening in the opposite direction moved while passing through the plurality of binding holes during binding.

In this case, the drawing shows that the cross-sectional shape of the partition wall 145d has a triangular shape as the edge portion 145e is formed singly on the outer surface side, but the edge portion 145e is formed in two so as to be rectangular. It may be formed in a cross-sectional shape of, and this modification is within the scope of the present invention.

Referring to FIG. 6D, when the wire L extending outwardly of the first binding hole 145a is pulled, a portion La of the wire L is outside the end Lb of the wire L. Bonding is completed by pressing.

At this time, as the wire (L) is pulled, the guide protrusion (144e), each edge portion (145e) formed in the partition wall (145d), the second binding hole (145b) and the third binding hole (145e) As the wire (L) is in contact with the stepped edge of each inner end of the sharply bent portion is formed. Accordingly, the wire (L), which has been bound, may be fixed in a solid state, and a malfunction due to the wire (L) being released and separated even when used for a long period of time may be prevented in advance.

In addition, the present invention is inconvenient such as rotating the reel unit 140 to bind both ends of the wire L since the wire binding unit 145 is symmetrically arranged horizontally with respect to the central partition wall 146 Is minimized. That is, it is possible to easily bind both ends of the wire L to the left and right wire binding portions 145 in a state in which the fastening guide marking portions 142c are disposed toward the operator.

In addition, when the operator simultaneously grips and pulls the wire L with the other hand while holding the front side of the reel 140 with one hand, the binding of both ends of the wire L may be achieved at the same time. In this case, a grip groove 140g may be formed at the front side of the reel unit 140 to facilitate the gripping of the operator.

On the other hand, Figure 7 is a partial projection example viewed from the upper side of a modified example of the reel portion applied to the wire winding adjustment device according to an embodiment of the present invention. In this modified example, the basic configuration except for the one side inner wall 144r of the fastening groove 144 is the same as that of the above-described embodiment, so a detailed description of the same configuration will be omitted. At this time, it is preferable to understand that the part marked in bold on the drawing is for distinguishing the binding hole/groove part from the solid body.

As shown in FIG. 7, the one inner wall 144r may be formed in a convex shape toward the front side. That is, the inner end of the third fastening hole 145c may be stepped forward than the inner end of the first fastening hole 145a and the second fastening hole 145b. Accordingly, the third fastening hole 145c is formed with a predetermined pressing step in the front and rear direction with each inner end portion of the first fastening hole 145a and the second fastening hole 145b.

Accordingly, a portion (La) of the wire (L) passing through the first binding hole (145a) and the second binding hole (145b) is toward the fastening groove (144) through the third binding hole (145c). The force to press the end (Lb) of the wire (L) that is drawn may be transmitted more strongly. Through this, the wire (L) can be more rigidly bound to the reel unit (140A), and the wire (L) when rotating the product in a state fixed to the tightening object or the assembly process of the wire winding control device Can be prevented from being arbitrarily separated from the reel unit 140A.

In this case, in the drawing, the one side inner wall 144r is shown in a convex shape to be rounded to the front side, but the central side of the one inner wall through which the third fastening hole 145c penetrates is the first fastening hole 145a and the second The binding hole 145b may be protruded stepwise in a stepped manner so as to be disposed more forward than both ends of the inner wall on which the binding hole 145b is formed. That is, if the inner end of the third fastening hole 145c is a structure that can be formed in front of the inner end of the first fastening hole 145a and the second fastening hole 145b, the inner wall of one side is various It can be formed convex to the front side in a shape.

Through this, the wire winding adjustment device 100 according to the present invention has a central portion through which the both ends of the wire are bound in a rotationally symmetrical form in a narrow space on the outer circumference side, unlike the conventional one, the reel portion 140 is the driving protrusion ( 115) does not have a penetrating configuration.

Therefore, it can be used as a whole as a via/binding space for binding the wire L to the central portion of the reel unit 140. In addition, as each of the binding holes 145a, 145b, and 145c is formed in a pair symmetrically with respect to the central partition wall 146, the binding direction is constant, so that it is easy to install and bind.

In addition, one side inner wall 144b of the fastening groove 144 is formed in a straight or convex shape, and the protrusion is formed on the bottom surface of the pressing communication part 144a corresponding to the third fastening hole 145c. 149) is established. Accordingly, as the pressing step increases, the end (Lb) of the wire (L) is pressed by a portion (La) of the wire (L) and the frictional area between each other increases, so that it can be firmly bound. .

In addition, through the guide protrusion 144e protruding toward the front side, the inlet direction is the same, and a partition between the first binding hole 145a and the third binding hole 145b penetrated adjacently is divided. Through this, since the end (Lb) of the wire (L) is accurately guided and moved to the via/binding space continuously formed in the front side of each of the binding holes (145a, 145b, 145c), accuracy and convenience when assembling the product This can be significantly improved.

In addition, the fastening guide marking part 142c is indicated by numbers or arrows on the outer surface of the reel part 140 corresponding to each of the fastening holes 145a, 145b, and 145c. Accordingly, since it is possible to intuitively check not only the penetrating position of each of the binding holes 145a, 145b, and 145c, but also the binding sequence, even a beginner who lacks work experience can easily bind the wires, thereby remarkably improving productivity. have.
