The outer edge of the abutting member 34 abuts against the groove wall of the receiving groove 28. 282. The abutting member 34 has a top surface 342, a bottom surface 344, and a communication groove 346 communicating with the top surface 342 and the bottom surface 344 (as shown in FIGS. 2 and 4). Referring to FIG. 4 and FIG. 5 again, the abutting member 34 has an outer diameter (R2), and the outer diameter (R2) of the abutting member 34 is slightly larger than the inner diameter (R1) of the receiving groove 28. In this embodiment, the difference (D) between the outer diameter (R2) of the abutting member 34 and the inner diameter (R1) of the receiving groove 28 is between 0.04 and 0.22 mm, wherein When the difference (D) between the outer diameter (R2) of the joint member 34 and the inner diameter (R1) of the accommodating groove 28 is between 0.08 and 0.16 mm, the hinge unit 10 of the present invention has a better handling feel. It should be noted that the outer diameter (R2) of the abutting member 34 refers to twice the distance from the center thereof to the circumference of the non-connecting groove 346.
如第2圖至第5圖所示，於本實施例中，該桿體32概呈圓柱狀且由金屬、塑膠或複合材料所製成，該桿體32具有一限位部322鄰近於桿體32之頂端，該限位部322係可由但不限於該桿體32之外緣朝心軸22之方向凹陷形成，該抵接件34係容設於該限位部322，於其他可能的實施方式，限位部也可是在管體外周面設有複數凸點之結構（圖中未示），藉以增加限位部與抵接件之間的摩擦力。該抵接件34係由彈性體所製成，該彈性體係可為但不限於矽氧橡膠（Silicone Rubber）或丁腈橡膠（Nitrile Butadiene Rubber）等材質。此外，於本實施例中，該抵接件34之連通槽346之數量為四並呈環狀等間隔分佈，但實際上該連通槽346的數量至少為一即可，其中，當該連通槽346的數量係介於二至六之間的的正整數時，具有較佳的操作手感，此外，當該抵接件34之硬度係介於55A至65A之間時，操作手感亦較佳，該硬度的計量單位為Shore A，該硬度是透過蕭式硬度計(Shore Durometer)進行量測；再者，於本實施例中，各該連通槽346概呈平行於該心軸22之方向且彼此並未相互連通，但於其他可能的實施例中，各該連通槽346亦可呈弧形或其他形狀分佈，且不一定要平行於該心軸22（圖中未示），只要各該連通槽346均有連通該頂面342及該底面344即可，此外各該連通槽346亦可於部分區段相互連通（圖中未示）。再者，該連通槽346之各區段的槽寬與槽深可以相同也可不同（圖中未示），可依據使用或製造的需求相對應地調整。As shown in FIG. 2 to FIG. 5, in the embodiment, the rod body 32 is substantially cylindrical and is made of metal, plastic or composite material. The rod body 32 has a limiting portion 322 adjacent to the rod. The abutting portion 322 is recessed in the direction of the mandrel 22, and the abutting member 34 is received in the limiting portion 322, and other possible In the embodiment, the limiting portion may also be a structure (not shown) having a plurality of bumps on the outer surface of the tube body, thereby increasing the friction between the limiting portion and the abutting member. The abutting member 34 is made of an elastic material, which may be, but not limited to, a material such as silicone rubber or Nitrile Butadiene Rubber. In addition, in the present embodiment, the number of the communication grooves 346 of the abutting member 34 is four and is equally spaced in a ring shape, but the number of the communication grooves 346 is actually at least one, wherein the communication groove is The number of 346 is a positive integer between two and six, and has a better operational feel. Further, when the hardness of the abutting member 34 is between 55A and 65A, the operational feel is also better. The hardness is measured in Shore A, and the hardness is measured by a Shore Durometer; further, in the embodiment, each of the communication grooves 346 is substantially parallel to the direction of the mandrel 22 and In other possible embodiments, each of the communication grooves 346 may also be curved or other shapes, and need not be parallel to the mandrel 22 (not shown), as long as each The communication groove 346 may communicate with the top surface 342 and the bottom surface 344. Further, each of the communication grooves 346 may communicate with each other in a partial section (not shown). Furthermore, the groove width and the groove depth of each section of the communication groove 346 may be the same or different (not shown), and may be adjusted correspondingly according to the needs of use or manufacture.
由上述結構可知，透過該調整桿30之抵接件34抵接於該管體20之容置槽28的槽壁282的方式，使得該調整桿30與該管體20之間具有適當之摩擦力，因此當使用者依照使用需求調整該調整桿30及該管體20的相對位置與相對角度後，透過該摩擦力可使該調整桿30及該管體20固定於調整後的位置。此外，本創作更透過該抵接件34之連通槽346的設置，讓位於該連通槽346之上下兩端的空氣得以相互流動，進而避免該管體20之容置槽28與該調整桿30之間形成封閉空間，因此當使用者調整該轉軸單元10之管體20及調整桿30的相對位置時，特別是將該調整桿30沿該心軸22之方向相對該管體20滑移時，不會因為該管體20之容置槽28與該調整桿30之間的氣壓升降導致調整時具有阻礙感，故能有效提升調整桿30相對滑移的順暢性。具體而言，如第6圖所示，當該調整桿30與該管體20係相對遠離時，空氣會由外部自管體20之開口端24流入，並通過該抵接件34之連通槽346到達該管體20之封閉端26；相反地，如第7圖所示，當該調整桿30與該管體20係相對靠近時，空氣會由該管體20之封閉端26流經該抵接件34之連通槽346，最後從該管體20之開口端24流出。It can be seen from the above structure that the abutting member 34 of the adjusting rod 30 abuts against the groove wall 282 of the receiving groove 28 of the tubular body 20, so that the adjusting rod 30 and the tubular body 20 have appropriate friction. Therefore, when the user adjusts the relative position and the relative angle of the adjusting rod 30 and the tubular body 20 according to the use requirement, the adjusting rod 30 and the tubular body 20 can be fixed to the adjusted position by the frictional force. In addition, the creation of the communication groove 346 of the abutting member 34 allows the air at the lower ends of the communication groove 346 to flow with each other, thereby avoiding the receiving groove 28 of the pipe body 20 and the adjusting rod 30. A closed space is formed between the two, so that when the user adjusts the relative position of the tubular body 20 and the adjusting rod 30 of the rotating shaft unit 10, especially when the adjusting rod 30 is slid relative to the tubular body 20 in the direction of the spindle 22 Therefore, the air pressure between the accommodating groove 28 of the tubular body 20 and the adjusting rod 30 does not cause a feeling of hindrance during the adjustment, so that the smoothness of the sliding of the adjusting rod 30 can be effectively improved. Specifically, as shown in FIG. 6, when the adjusting rod 30 is relatively far from the tubular body 20, air flows from the open end 24 of the tubular body 20 from the outside and passes through the communicating groove of the abutting member 34. 346 reaches the closed end 26 of the tubular body 20; conversely, as shown in Figure 7, when the adjustment rod 30 is relatively close to the tubular body 20, air will flow through the closed end 26 of the tubular body 20 The communication groove 346 of the abutment member 34 finally flows out from the open end 24 of the pipe body 20.
