Description
本創作係涉及一種具有收放線結構的延長線。 This creative department relates to an extension cord with a retractable line structure.
傳統的具有收放線結構的延長線包含有一第一轉盤及一第二轉盤。第一轉盤與第二轉盤面向彼此可相互轉動地結合，且第一轉盤與第二轉盤之間夾設形成一收線空間。使用者透過旋轉第一轉盤與第二轉盤來將線材捲收於收線空間中。 The conventional extension cord with a retractable line structure includes a first turntable and a second turntable. The first turntable and the second turntable face each other and are rotatably combined with each other, and a wire take-up space is sandwiched between the first turntable and the second turntable. The user winds the wire in the wire take-up space by rotating the first turntable and the second turntable.
為了避免過度旋轉而使線材在收線過程中受到拉扯損壞，現有技術的手動具有收放線結構的延長線在第一轉盤上形成有一弧形滑槽，弧形滑槽上的任一點與第一轉盤的轉動中心的距離相同，即弧形滑槽是沿著以該轉動中心為圓心的圓延伸。相對地，在第二轉盤上形成有一凸柱，凸柱與第二轉盤的轉動中心之距離等於弧形滑槽上的任一點與第一轉盤的轉動中心的距離，且組裝後第二轉盤的轉動中心與第一轉盤的轉動中心相重合，因此於第二轉盤相對於第一轉盤轉動時，凸柱可沿著弧形滑槽移動地設於弧形滑槽中，藉此弧形滑槽的兩端便形成止擋點。於是，當凸柱因第一轉盤與第二轉盤相互轉動而沿著弧形滑槽移動至弧形滑槽的其中一端時，第一轉盤與第二轉盤便會因為弧形滑槽止擋凸柱而停止進一步沿著同一方向繼續轉動，藉此即可避免過度旋轉而使線材損壞。 In order to avoid excessive rotation and damage to the wire during the take-up process, the prior art manual extension cord with take-up and take-up structure is formed with an arc-shaped chute on the first turntable, and any point on the arc-shaped chute is connected to the first The distance between the rotation centers of the turntable is the same, that is, the arc-shaped sliding groove extends along a circle centered on the rotation center. In contrast, a convex post is formed on the second turntable, and the distance between the convex post and the center of rotation of the second turntable is equal to the distance between any point on the arc chute and the center of rotation of the first turntable. The center of rotation coincides with the center of rotation of the first turntable. Therefore, when the second turntable rotates relative to the first turntable, the protruding column is movably arranged in the arc chute along the arc chute, whereby the arc chute The two ends of it form a stop point. Therefore, when the convex post moves along the arc-shaped chute to one end of the arc-shaped chute due to the mutual rotation of the first turntable and the second turntable, the first and second turntables will stop convexly because of the arc-shaped chute. The column stops further rotating in the same direction, thereby avoiding excessive rotation and damage to the wire.
然而，現有技術的具有收放線結構的延長線由於凸柱是固定於第二轉盤上，第二轉盤轉動時凸柱僅能與轉動中心保持相同距離，因此所對應 的弧形滑槽最多只能延伸將近一周。而受到弧形滑槽兩端的限制，使得第一轉盤與第二轉盤至多僅能相對於彼此旋轉一圈，因此其所能捲收的線材長度也同樣會受到限制。 However, in the prior art extension cord with a retractable wire structure, because the convex post is fixed on the second turntable, the convex post can only keep the same distance from the center of rotation when the second turntable rotates. The arc chute can only extend for nearly one week at most. However, due to the limitation of the two ends of the arc-shaped sliding groove, the first turntable and the second turntable can only rotate one circle relative to each other at most, so the length of the wire that can be wound is also limited.
為了要增加具有收放線結構的延長線所能捲收的線材長度，故如何在形成止擋點藉以避免過度旋轉的同時，還能使第一轉盤與第二轉盤可以相對於彼此旋轉超過一圈，則成為具有收放線結構的延長線技術領域中必須克服的問題。 In order to increase the length of the wire that can be rolled up by the extension cord with the take-up and pay-off structure, how to form a stop point to avoid excessive rotation, and at the same time make the first and second turntables rotate more than one turn relative to each other , It becomes a problem that must be overcome in the technical field of extension cords with retractable wire structure.
有鑑於前述之現有技術的缺點及不足，本創作提供一種具有收放線結構的延長線，其同樣能夠形成止擋點藉以避免過度旋轉，並且同時還能使第一轉盤與第二轉盤可以相對於彼此旋轉超過一圈，進而增加其能捲收的線材長度。 In view of the aforementioned shortcomings and deficiencies of the prior art, this creation provides an extension cord with a retractable line structure, which can also form a stop point to avoid excessive rotation, and at the same time, it can also enable the first and second turntables to be relatively Rotate each other more than one circle, thereby increasing the length of the wire that can be wound.
為達到上述的創作目的，本創作所採用的技術手段為設計一種具有收放線結構的延長線，其中包含：一第一轉盤，其包含有一第一結合面；一第一滑軌，其設於該第一結合面且沿著該第一轉盤的徑向方向延伸；一第二轉盤，其能轉動地與該第一轉盤相互結合且包含有一第二結合面，其面向該第一轉盤的該第一結合面，且與該第一結合面夾設形成有一收線空間；一第二滑軌，其設於該第二結合面且呈螺旋狀延伸； 一滑動件，其能移動地設於該第一轉盤的該第一滑軌，且同時能移動地設於該第二轉盤的該第二滑軌；一線材，其選擇性地容置於該收線空間內。 In order to achieve the above creative purposes, the technical means used in this creation is to design an extension cord with a retractable line structure, which includes: a first turntable, which includes a first joint surface; and a first slide rail, which is set at The first coupling surface extends along the radial direction of the first turntable; a second turntable is rotatably coupled with the first turntable and includes a second coupling surface facing the first turntable A first joint surface, and a wire take-up space is formed between the first joint surface; a second slide rail is arranged on the second joint surface and extends in a spiral shape; A sliding member movably provided on the first slide rail of the first turntable, and at the same time movably provided on the second slide rail of the second turntable; a wire, which is selectively accommodated in the In the take-up space.
本創作的優點在於，藉由在第一轉盤上設有沿著徑向方向延伸的第一滑軌，並且在第二轉盤上將第二滑軌設計成螺旋狀延伸，且使滑動件同時能移動地設於第一滑軌與第二滑軌內。藉此，第二滑軌的兩端點同樣能形成止擋點，使滑動件移動至第二滑軌的其中一端點後便無法再朝同一方向前進，可以避免過度旋轉；同時，由於滑動件設於第一轉盤的第一滑軌內，於是當滑動件在第二轉盤上沿著螺旋狀的第二滑軌移動時，滑動件同時能夠相對於第一轉盤沿著第一轉盤的徑向移動，藉此滑動件便能朝向或者遠離螺旋狀的中心移動而不會受到第一轉盤的限位。換言之，第一轉盤與第二轉盤在旋轉時，滑動件與旋轉中心的距離非固定，也就是說在第一轉盤上能夠藉由第一滑軌接近或者遠離旋轉中心，且在第二轉盤上能夠藉由第二滑軌接近或者遠離旋轉中心。如此一來，螺旋狀的第二滑軌便能使第一轉盤相對於第二轉盤旋轉超過一圈。綜上所述，本創作夠形成止擋點藉以避免過度旋轉，並且同時還能使第一轉盤與第二轉盤可以相對於彼此旋轉超過一圈，進而增加其能捲收的線材長度。 The advantage of this creation is that by providing a first slide rail extending in the radial direction on the first turntable, and designing the second slide rail on the second turntable to extend in a spiral shape, the slide can be simultaneously It is movably arranged in the first slide rail and the second slide rail. In this way, the two end points of the second slide rail can also form stop points, so that the slide member cannot move in the same direction after moving to one of the end points of the second slide rail, which can avoid excessive rotation; at the same time, because the slide member Set in the first slide rail of the first turntable, so when the sliding member moves along the spiral second slide rail on the second turntable, the slide member can also be relative to the first turntable along the radial direction of the first turntable As a result, the sliding member can move toward or away from the spiral center without being restricted by the first turntable. In other words, when the first turntable and the second turntable are rotating, the distance between the sliding member and the center of rotation is not fixed, that is to say, on the first turntable, the first slide rail can approach or move away from the center of rotation, and on the second turntable The second slide rail can be used to approach or move away from the center of rotation. In this way, the spiral second slide rail can make the first turntable rotate more than one revolution relative to the second turntable. To sum up, this creation can form a stopping point to avoid excessive rotation, and at the same time, it can also make the first and second turntables rotate more than one turn relative to each other, thereby increasing the length of the wire that can be wound.
