Description

连弩 技术领域
本发明公开了一种连弩。
背景技术
弩也被称作“窝弓”、“十字弓”。是用来射箭的一种武器。弩是一种装有臂的弓，主要由弩臂、弩弓、弓弦和弩机等部分组成，弩弓横于弩臂前端；弩臂上设有箭槽，弩机设置在箭槽尾端，弓弦位于弩臂的上方，其两端栓挂在两片弩弓上，弦体挂在弩机中的挂钩上，发射时，将箭矢放在箭槽中，扳开挂钩，利用张开的弩弓带动弓弦形成急速回弹的动能，将箭高速射出，在历史上记载有诸葛连弩，能够一次发射十支箭矢，由于诸葛连弩处于失传状态，许多人都想复制诸葛连弩，但现有仿制的诸葛连弩，区别仅在于弩臂上的箭槽数量的多少，其余结构与普通弩的结构大致相同，由于挂弦后位于挂钩两侧的弓弦呈倾斜角度，在击发时，多箭槽中两侧箭槽的箭矢被先击发，位于中间箭槽的箭矢被后击发，期间弓弦的动能有所衰减，导致箭矢的散布半径大，命中精度低。现有连弩为了保证箭矢的射击初速，通常采用磅数较大的弓弦用来击打多支箭矢，上弦较为困难，并且箭矢需要逐根布置在箭槽内，射击间隔很长，重复射击的速度很慢。
发明内容
本发明的目的是提供一种连弩，能够同时发射多支箭矢，命中精度高、射击速度快。
本发明的技术方案1是：连弩，包括弩臂(1)、弓弦(9)、弩机，其 特征在于：弩臂上装有滑块(6)，滑块沿弩臂的纵向与弩臂滑动连接，弩臂的顶部固装有箭舱(4)，箭舱设有多个纵向贯通的箭孔(3)，每个箭孔设有一个滑动连接的击锤(5)，各击锤与滑块固连，所述的弓弦位于弩臂的下方，弓弦的弦体与滑块挂接，当滑块位于后止点时滑块活动挂接在弩机上。
基于技术方案1的结构，本发明的技术方案2是：所述的弩机具有扳把(20)、勾板(16)、弹簧(14)，扳把的上部和勾板的中部各通过轴销铰接在弩臂上，弹簧的一弹力端与弩臂压接、另一弹力端与位于轴销下方的扳把压接，勾板的后端与扳把的中部活动钩接，所述的滑块位于后止点时滑块活动挂接在勾板的前端。
基于技术方案1的结构，本发明的技术方案3是：弩臂沿纵向设有长条通孔(22)，所述的滑块限位于长条通孔内与弩臂滑动连接。
基于技术方案1的结构，本发明的技术方案4是：滑块通过滑道(2)与弩臂滑动连接，所述的滑道固装在弩臂上。
基于技术方案1的结构，本发明的技术方案5是：所述的箭舱具有基座(26)，基座上设有多条纵向贯通的箭槽(25)，各箭槽的上方依次叠摞有多个截面为U形的箭鞘(27)，各箭鞘的宽度大于对应箭槽槽口的宽度，最下面一层的箭鞘其底面与对应的箭槽构成所述的箭孔，各箭鞘前端的底面设有凸起部(33)，各击锤或滑块的后端装有轴杆(30)，各轴杆上装有铰接的顶板(29)，常态下各顶板的后端翘起与对应箭鞘底面的凸起部相对；各箭槽收纳在底部开口的盒体(28)中，盒体固装在基座或弩臂上，盒体的后立面上设有与最下面一层各箭鞘截面位置对应的多个U形豁口(32)。
基于技术方案1的结构，本发明的技术方案6是：弩臂底部的前端装有 自动收线器(38)、后端装有卷线器(34)，自动收线器和卷线器之间装有拉线(35)，拉线上栓有挂钩(37)，该挂钩活动挂接在所述的滑块上。
基于技术方案6的结构，本发明的技术方案7是：所述的卷线器是电动卷线器。
基于技术方案1至7中的任一结构，本发明的技术方案8是：所述的箭孔数量为十个。
基于技术方案1至7中的任一结构，本发明的技术方案8是：所述的击锤前端装有可拆卸的击锤头(39)。
本发明的优点是：箭孔中装有箭矢，通过弓弦带动滑块移动，将弓弦的动能通过滑块和击锤击发箭矢，能够同时发射多支箭矢，由于击锤可并排布置，能够同时击发所有箭矢，使所有箭矢受力均匀，击发出的箭矢散布半径小，命中精度高。本申请的弩机结构简单，工作稳定。通过长条通孔限位滑块，能消除滑块在击发时的震颤，使击锤击打箭矢稳定，进一步提高连弩的命中精度。滑道能降低滑块与弩臂的间的摩擦力，不仅能够提高连弩的命中精度，还能够省力。设置多个箭鞘，每个箭鞘中装有箭矢，滑块后端的顶板顶在对应箭鞘的凸起部上，滑块上弦时，能将箭鞘从盒体后立面的豁口退出，箭鞘中的箭矢掉落在箭槽中，击发后，重复上述动作，能快速向箭槽中补充箭矢，重复射击速度极快。将挂钩挂在滑块上，使用卷线器开弓，能够省力，采用电动卷线器，能进一步节省体力，提高重复射击的速度。

为了进一步提高张弓效率，节省人力，在弩臂底部的前端装有自动收线器38、后端装有卷线器34，自动收线器和卷线器之间装有拉线35，拉线上栓有挂钩37，该挂钩活动挂接在所述的滑块上；根据此结构，本实施例中，滑块上固连有滑块挂杆36，该挂杆用于使挂钩活动挂接在滑块上，挂钩上的钩开口冲向后方，以便在上弦后，能利用自动收线器回卷的功能自动与滑块挂杆脱钩进行复位，避免其影响滑块的移动。所述的自动收线器和卷线器为市售产品，自动收线器的工作原理与卷尺的工作原理类似，通过螺旋板簧蓄力来回收拉线，卷线器一般具有线卷，拉线的一端固定在线卷上，通过转动线卷缠绕拉线，起到卷线的目的，本实施例列举了两种卷线器，一种为手摇式卷线器另一种为电动卷线器，手摇式卷线器是将线卷装在弩臂上，在线卷的两侧设有摇把，通过摇动摇把31驱动线卷转动用于卷线；如图14所示，所述电动卷线器包括线卷、减速电机40和电池42，减速电机的输出轴与线卷的卷轴动力联接，电机的壳体固定在弩臂上，电池采用锂电池，安装在后握把中，电池通过电线41与减速电机电连接，电池的电输出端或电线上或减速电机上设有电开关，用于控制减速电机工作，通过电动卷线能够进一步提高张弓效率，节约人力。
本申请的连弩，所述的箭孔数量限定为十个，用于实现诸葛连弩“一弩十矢具发”的技术效果；各击锤的前端装有可拆卸的击锤头39，该结构能方便的对击锤头进行更换，便于维护维修。
