所述卡制单元可釆用多种结构方式， 以下通过三个实施例分别详述该卡制 单元的结构： 实施例一  The card unit can adopt various structural modes. The structure of the card unit is described in detail in the following three embodiments: Embodiment 1
如图 3至图 5所示， 所述卡制单元包括： 活动杆 71、 卡制片 72、 活动压 片 73、 扭簧 74、 锁定件 75、 压缩弹簧 76和弹片 77。 其中，  As shown in FIGS. 3 to 5, the card unit includes: a movable lever 71, a card piece 72, a movable pressing piece 73, a torsion spring 74, a locking member 75, a compression spring 76, and a resilient piece 77. among them,
所述活动杆 71竖向设置于按座体 22内， 一压缩弹簧 714向上作用于该活 动杆 71使之具有保持上移的趋势， 活动杆 71顶部设有一顶压面 711而下部向 外设有突出部 71 3，所述顶压面 711位于中棒 1折叠时其外管 11可触及的位置。 所述卡制片 72位于活动杆 71 外侧下部的位置， 其上端铰接于按座体 22 上， 其上部往内设有弧形凸起 722， 其下部向内设有卡钩 721。 所述弹片 77— 端固定在按座体 22上， 另一端往内作用于所述卡制片 72使之保持向内转动并 与所述棘轮 6相抵的趋势。 The movable rod 71 is vertically disposed in the pressing body 22, and a compression spring 714 acts upward on the movable rod 71 to maintain a tendency to move upward. The top of the movable rod 71 is provided with a pressing surface 711 and a lower peripheral portion. There is a protruding portion 71 3 which is located at a position where the outer tube 11 can be accessed when the middle rod 1 is folded. The card piece 72 is located at a lower portion of the outer side of the movable rod 71, and its upper end is hinged to the base body 22, the upper portion of which is provided with an arcuate projection 722, and the lower portion thereof is provided with a hook 721 inward. The elastic piece 77 is fixed at the end of the seat body 22, and the other end acts inwardly on the card piece 72 to keep it inwardly rotated and abut against the ratchet 6.
所述锁定件 75水平设置在按座体 22内且可前后滑动， 其上开设有可供所 述活动杆 71穿过的缺口 751 ,所述压缩弹簧 76朝活动压片 73的方向推抵所述 锁定件 75使其上的缺口 751具有与所述活动压片 73的位置错开的趋势。  The locking member 75 is horizontally disposed in the seat body 22 and is slidable back and forth, and has a notch 751 through which the movable rod 71 passes, and the compression spring 76 is pushed toward the movable pressing piece 73. The locking member 75 has a notch 751 thereon that has a tendency to be displaced from the position of the movable pressing piece 73.
所述活动压片 73铰接于所述开收伞按钮 21 的内侧， 所述扭簧 74的一边 与开收伞按钮 21相抵， 另一边与所述活动压片 73自由端相抵， 使所述活动压 片 73具有向上转动至水平位置的趋势， 且该活动压片 73位于水平位置时的高 度正好可与所述锁定件 75相对， 此时， 活动压片 73的自由端处于所述中管 12 折叠时可触及的位置。  The movable pressing piece 73 is hinged to the inner side of the open umbrella button 21, one side of the torsion spring 74 is opposite to the open umbrella button 21, and the other side is opposite to the free end of the movable pressing piece 73, so that the activity The pressing piece 73 has a tendency to rotate upward to a horizontal position, and the height of the movable pressing piece 73 in the horizontal position is just opposite to the locking piece 75, and at this time, the free end of the movable pressing piece 73 is in the middle tube 12 The position that is accessible when folded.
在中棒 1处于完全折叠状态时， 如图 6所示， 所述中棒 1的外管 11和中 管 12折叠于按座体 22内， U型件 23上的凸块被压缩弹簧 24向前推至卡入外 管 11 的缺口内从而将中棒锁定， 活动压片 73的自由端被中管 12压下， 所述 活动杆 71的顶压面 711被中棒 1的外管 11向下压至锁定件 75以下的位置， 此时， 压缩弹簧 76将锁定件 75向前推使得其上的缺口 751与活动杆 71的位 置错开， 这样活动杆 71 即被锁定件 75阻挡而不能上移， 这时， 活动杆 71下 部的突出部 713推抵卡制片 72上的弧形凸起 722使卡制片 72的下部外翘脱离 所述棘轮 6 , 此时， 所述拉索收纳转轴 4可以自由转动以放松安全拉索 3。  When the middle rod 1 is in the fully folded state, as shown in FIG. 6, the outer tube 11 and the middle tube 12 of the middle rod 1 are folded in the pressing body 22, and the projections on the U-shaped member 23 are pressed by the compression spring 24 Pushing into the notch of the outer tube 11 to lock the middle rod, the free end of the movable pressing piece 73 is depressed by the middle tube 12, and the pressing surface 711 of the movable rod 71 is directed by the outer tube 11 of the middle rod 1 Pressing down to the position below the locking member 75, at this time, the compression spring 76 pushes the locking member 75 forward so that the notch 751 thereon is displaced from the position of the movable lever 71, so that the movable lever 71 is blocked by the locking member 75 and cannot be moved. At this time, the protruding portion 713 of the lower portion of the movable rod 71 pushes against the curved protrusion 722 on the clamping piece 72 to cause the lower portion of the locking piece 72 to be pivoted out of the ratchet 6 . At this time, the cable accommodates the rotating shaft. 4 can be free to rotate to relax the safety cable 3.
当第一次按压开收伞按钮 21时， 如图 7所示， 开收伞按钮 21推动 U型件 23抵抗弹簧 24的推力后移， 其上的凸块脱离中棒外管 11上的缺口， 中棒 1被 释放并在开伞弹簧的作用下向上伸展， 外管 11和中管 12逐步脱离按座体 22 , 但此时， 活动杆 71仍然被锁定件 75 阻挡不能上移， 卡制片 72保持与棘轮 6 脱离的状态， 棘轮 6及拉索收纳转轴 4得以自由转动以释放绕在其上的安全拉 索 3以配合中棒 1的伸展。 在松开开收伞按钮 21后， 所述活动压片 73在扭簧 74的作用下向上抬起至水平位置并与所述锁定件 75的位置相对。 当第二次按压开收伞按钮 21收伞时， 如图 8所示， 所述活动压片 7 3向内 推动锁定件 75使得其上的缺口 751与活动杆 71的位置对应， 此时， 所述活动 杆 71被释放并在压缩弹簧 714 的作用下向上伸出锁定件 75上方， 活动杆 71 下部的突出部 71 3移至卡制片 72上弧形凸起 722的上方， 所述卡制片 72的下 部卡钩 721在弹片 77的作用下向内转动并与棘轮 6的制动面 61卡扣， 此时， 该棘轮 6及拉索收纳转轴 4只能单向转动以卷绕安全拉索 3而不能放松安全拉 索 3 , 这样一来， 在向下压缩中棒 1 的过程中， 即使不小心松手， 上巢或其联 动部件仍然会被安全拉索 3拉住使中棒不能向上反弹， 使用起来很安全。 实施例二 When the umbrella button 21 is pressed for the first time, as shown in FIG. 7, the open umbrella button 21 pushes the U-shaped member 23 back against the thrust of the spring 24, and the bump thereon is disengaged from the gap on the outer tube 11 of the middle rod. The middle rod 1 is released and extended upward by the opening spring, and the outer tube 11 and the middle tube 12 are gradually separated from the pressing body 22, but at this time, the movable rod 71 is still blocked by the locking member 75 and cannot be moved up, and the locking is performed. The blade 72 is kept in a state of being disengaged from the ratchet 6, and the ratchet 6 and the cable accommodating shaft 4 are freely rotated to release the safety cable 3 wound thereon to fit the extension of the middle bar 1. After the open/close button button 21 is released, the movable pressing piece 73 is lifted up to the horizontal position by the torsion spring 74 and is opposed to the position of the locking piece 75. When the umbrella button 21 is pressed for the second time, as shown in FIG. 8, the movable pressing piece 73 pushes the locking member 75 inwardly so that the notch 751 thereon corresponds to the position of the movable rod 71. The movable lever 71 is released and protrudes upwardly above the locking member 75 by the compression spring 714, and the protruding portion 71 3 of the lower portion of the movable lever 71 is moved over the arcuate projection 722 on the locking piece 72, the card The lower hook 721 of the tablet 72 is rotated inwardly by the elastic piece 77 and is engaged with the braking surface 61 of the ratchet 6. At this time, the ratchet 6 and the cable receiving shaft 4 can only be rotated in one direction for winding safety. Cable 3 can not relax the safety cable 3, so that in the process of compressing the rod 1 downward, even if it is accidentally released, the upper nest or its linkage parts will still be pulled by the safety cable 3 so that the middle rod cannot Bounce up and it is safe to use. Embodiment 2
如图 9和图 10所示， 所述卡制单元包括： 活动杆 71、 卡制片 72、 活动压 片 73、 扭簧 74、 弹片 77和挡止凸块 76。 其中，  As shown in Figs. 9 and 10, the card unit includes: a movable lever 71, a card piece 72, a movable pressing piece 73, a torsion spring 74, a spring piece 77, and a stopper projection 76. among them,
所述卡制片 72、 弹片 77、 活动压片 7 3和扭簧 74的结构与实施例一相同， 所述活动杆 71的结构也与实施例一基本相同， 所不同的是， 活动杆 71上部还 固设有一个具有可向内收弹性的弹性体 712 , 该弹性体 712外侧下部为一个越 向下越往内收的导向斜面或弧面。 所述挡止凸块 76固设在按座体 22内并凸设 于所述弹性体 712的导向斜面或弧面下方， 由此该弹性体 712只在内收时才能 越过该挡止凸块 76。 所述活动压片 73的自由端在转至水平位置时其高度低于 所述挡止凸台 76底面的高度并处于所述中管 12折叠时可触及的位置。  The structure of the clamping piece 72, the elastic piece 77, the movable pressing piece 73 and the torsion spring 74 is the same as that of the first embodiment. The structure of the movable rod 71 is also basically the same as that of the first embodiment, except that the movable rod 71 is different. The upper portion is also fixed with an elastic body 712 having an inwardly retractable elasticity, and the outer lower portion of the elastic body 712 is a guiding inclined surface or a curved surface which is more downwardly and inwardly received. The blocking protrusion 76 is fixed in the seat body 22 and protrudes from the guiding slope or the curved surface of the elastic body 712, so that the elastic body 712 can pass over the blocking protrusion only when it is received. 76. The free end of the movable pressing piece 73 has a height lower than the height of the bottom surface of the blocking boss 76 when it is turned to the horizontal position and is in a position accessible when the middle tube 12 is folded.
在中棒 1处于完全折叠状态时， 如图 11所示， 所述中棒 1的外管 1 1和中 管 12被折叠于按座体 22内锁定， 活动压片 73的自由端被中管 12压下， 所述 活动杆 71的顶压面 7 1 1被中棒 1的外管 1 1向下压至挡止凸块 76以下的位置， 活动杆 71上的弹性体 712先内收通过挡止凸块 76后再恢复原位并顶在挡止凸 块 76底面， 这样活动杆 71 即被挡止凸块 76阻挡而不能上移， 这时， 活动杆 71下部的突出部 71 3推抵卡制片 72上的弧形凸起 722使卡制片 72的下部卡钩 721 外翘脱离所述棘轮 6， 此时， 所述拉索收纳转轴 4可以自由转动以放松安 全拉索 3。 当第一次按压开收伞按钮 21时， 如图 12所示， 中棒 1被释放并在开伞弹 簧的作用下向上伸展， 外管 11和中管 12逐步脱离按座体 22， 但此时， 活动杆 71仍然被挡止凸块 76阻挡不能上移， 卡制片 72保持与棘轮 6脱离的状态， 棘 轮 6及拉索收纳转轴 4得以自由转动以释放绕在其上的安全拉索 3以配合中棒 1的伸展。 在松开开收伞按钮 21后， 所述活动压片 73在扭簧 74的作用下向上 抬起至水平位置， 其自由端与挡止凸块 76下方弹性体 712的位置相对。 When the middle rod 1 is in the fully folded state, as shown in Fig. 11, the outer tube 1 1 and the middle tube 12 of the middle rod 1 are folded and locked in the seat body 22, and the free end of the movable pressing piece 73 is in the middle tube. 12 is pressed, the pressing surface 71 1 of the movable rod 71 is pressed downward by the outer tube 1 1 of the middle rod 1 to a position below the blocking projection 76, and the elastic body 712 on the movable rod 71 is firstly received. After the blocking block 76 is restored to the original position and is placed on the bottom surface of the blocking projection 76, the movable lever 71 is blocked by the blocking projection 76 and cannot be moved upward. At this time, the protruding portion 71 3 of the lower portion of the movable lever 71 is pushed. The arcuate projection 722 on the carding piece 72 causes the lower hook 721 of the carding piece 72 to be pivoted out of the ratchet wheel 6. At this time, the cable receiving reel 4 can be freely rotated to relax the safety cable 3. When the umbrella button 21 is pressed for the first time, as shown in Fig. 12, the middle rod 1 is released and extended upward by the opening spring, and the outer tube 11 and the middle tube 12 are gradually separated from the seat body 22, but this When the movable lever 7 1 is still blocked by the blocking projections 7 and cannot be moved up, the clamping piece 7 2 is kept out of the ratchet 6 , and the ratchet 6 and the cable receiving rotating shaft 4 are freely rotated to release the winding thereon.
