Abstract

A joint spindle for scissors or pliers is disclosed. An active connection structure through the coupling of a bolt and a nut is applied on the joint spindle. A washer, which couples exactly with the bolt and couldn't rotate radially, is provided between the bolt and the nut, and it is locked by the nut. When blades rotating, the washer coupled exactly with the bolt doesn't rotate. So the nut for locking blades doesn't rotate. The structure in the invention could assemble the two blades suitably and conveniently. It avails to advance the quality and lengthen the life of the tool.

Description

用于剪、 钳类工具的新型轴芯 技术领域  New shaft core for shearing and pliers tools
本发明涉及一种用于剪刀、 钳子、 裁刀、 铡刀之类的二刃体连接组装时 用的轴芯结构的改进。 背景技术  The present invention relates to an improvement in a core structure for use in a two-blade connection assembly such as scissors, pliers, a cutter, or a file. Background technique
所有剪刀、 钳子、 裁刀、 铡刀之类的五金工具都有一对具有剪、 切、 钳 等各种功能刃口的刃体。 把二刃体组装联接在一起的结构装置， 在这里称之 为轴芯。 传统的刀剪轴芯采用冷锻铆工艺， 以使相对二刃口的平面绝对保持 吻合。 采用冷锻铆工艺加工轴芯， 把握好铆时的力度十分重要， 因为下力的 轻重都会使生产出来的产品出现病疵。 然而冷锻铆的缺点就在于力度不易把 握 o  All hardware tools such as scissors, pliers, cutters, and boring tools have a pair of blades with various cutting edges, such as scissors, cutters, and nippers. The structural device that couples the two-blade assembly together is referred to herein as the core. The traditional knife-cutting core is cold forged and riveted so that the plane of the two cutting edges is absolutely consistent. It is very important to use the cold forging riveting process to machine the shaft core, and it is very important to grasp the strength of the riveting, because the weight of the lower force will make the produced products appear sick. However, the disadvantage of cold forging is that the strength is not easy to hold.
发明的公开  Disclosure of invention
本发明的主要目的是： 克服现有技术的不足， 从而开发一种能十分方便 地将相对二刃体恰到好处地组装在一起， 用于剪、 钳类工具的新型轴芯。  SUMMARY OF THE INVENTION The main object of the present invention is to overcome the deficiencies of the prior art and to develop a new type of shaft core which can be easily assembled with relatively two-blade bodies for shearing and pliers tools.
本发明的上述技术问题主要是通过下述技术方案得以解决的： 用于剪、 钳类工具的新型轴芯， 具有一对刃体及将刃体组装在一起的轴芯， 其特征在 于： 所述的轴芯是由穿过刃体轴孔的螺栓， 装在螺栓上与螺栓连成一体的垫 圈， 以及位于垫圈外面、 拧在螺栓上的螺帽组成； 所述的螺栓与垫圈之间在 配合段的截面形状是除圆形以外的任一几何形状； 所述垫圈的内孔是与螺栓 上配合段的几何形状相吻合的形状。  The above technical problems of the present invention are mainly solved by the following technical solutions: a new type of shaft core for a shearing and pliers tool, a pair of blade bodies and a shaft core for assembling the blade body, wherein: The shaft core is composed of a bolt passing through the shaft hole of the blade body, a washer integrally attached to the bolt on the bolt, and a nut which is located outside the washer and screwed on the bolt; the bolt is interposed between the bolt and the washer The cross-sectional shape of the mating segment is any geometric shape other than a circle; the inner bore of the washer is shaped to conform to the geometry of the mating segment on the bolt.
所述的螺栓可以是双头螺栓， 也可以是单头螺栓。  The bolt may be a stud bolt or a single stud bolt.
所述的垫圈与螺栓连成一体是指安装完成后， 垫圈与螺栓没有径向方向 的相对运动， 即垫圈与螺栓同步。  The fact that the washer and the bolt are integrally connected means that the washer and the bolt have no relative movement in the radial direction after the installation is completed, that is, the washer is synchronized with the bolt.
所述的任一几何形状如三角形、 六角形、 梯形等。  Any of the geometric shapes described are triangular, hexagonal, trapezoidal, and the like.
所述的配合段是指螺栓安装垫圈的距离范围， 即螺栓与垫圈相配合的那 一段距离范围。 所述的垫圈的内孔是与螺栓配合段几何形状相吻合（包括部分吻合与全 部吻合)， 以螺栓与垫圈不会产生径向转动为准。 实践证明螺栓与垫圈即使因 为活动配合的间隙而产生很小的径向转动， 也不会使螺帽产生松动， 因此可 以忽略不计。 The mating section refers to the distance range of the bolt mounting washer, that is, the distance range between the bolt and the washer. The inner hole of the washer is matched with the geometry of the bolt mating section (including partial anastomosis and full fit), and the bolt and the washer are not subject to radial rotation. Practice has proved that bolts and washers, even if they have little radial rotation due to the clearance of the active fit, do not loosen the nut and can therefore be ignored.
作为优选方案， 螺栓在配合段的截面形状是方形， 垫圈的内孔与螺栓上 配合段的方形截面相吻合， 以螺栓与垫圈不会产生径向转动， 最终保证螺帽 不会松动为准。  Preferably, the cross-sectional shape of the bolt in the mating section is square, and the inner hole of the washer coincides with the square cross section of the mating section of the bolt, so that the bolt and the washer do not cause radial rotation, and finally the nut is not loosened.
因此， 本发明由于采用螺栓与螺帽相配合的活动连接结构， 中间设有与 螺栓配合的垫圈， 而刃口因工作而转动时， 垫圈不会转动， 因此锁紧刃体的 螺帽也不会受影响而产生松动。 本发明能十分方便地将相对二刃体恰到好处 地组装在一起， 有利于提高工具质量， 延长使用寿命。 附图说明  Therefore, the present invention adopts a movable connecting structure in which a bolt and a nut are matched, and a washer which is matched with a bolt is arranged in the middle, and when the cutting edge is rotated by the work, the washer does not rotate, and therefore the nut of the locking blade body is not Will be affected and loosened. The invention can conveniently assemble the relatively two-blade body just rightly, which is beneficial to improving the quality of the tool and prolonging the service life. DRAWINGS

实现本发明的最佳方式 The best way to implement the invention
下面通过实施例， 并结合附图， 对本发明的技术方案作进一步具体的说 明。  The technical solutions of the present invention will be further specifically described below by way of embodiments and with reference to the accompanying drawings.
实施例：  Example:
如图 1所示， 在一对刃体 1的轴孔中装有螺栓 3， 实施例采用双头螺栓， 也可以是单头螺栓， 不过效果不及双头螺栓； 二刃体 1 的外侧， 紧贴装有二 垫圈 2， 二垫圈 2的内孔 21的几何形状可以是除圆形外的任一几何形状， 在 垫圈 2外面用螺帽 4锁紧。如图 2、 图 3所示垫圈 2的内孔采用方孔， 依靠垫 圈 2内孔 21的几何形状与螺栓 3上配合段 5形状的相吻合及精密配合， 垫圈 2在螺栓 3上不会沿径向转动，因此保持了垫圈 2外面用于锁紧的二螺帽 4不 会松动。  As shown in Fig. 1, a bolt 3 is arranged in the shaft hole of the pair of blade bodies 1. The embodiment uses a stud bolt or a single-head bolt, but the effect is inferior to the stud bolt; the outer side of the second blade body 1 is tight. The geometry of the inner bore 21 to which the two washers 2 are attached, the two washers 2 may be any geometric shape other than a circular shape, and is locked with a nut 4 outside the gasket 2. As shown in Fig. 2 and Fig. 3, the inner hole of the washer 2 adopts a square hole, and the geometry of the inner hole 21 of the washer 2 is matched with the shape of the matching section 5 on the bolt 3, and the precision fits, the washer 2 does not follow the bolt 3 The rotation is radial, so that the two nuts 4 for locking the outside of the gasket 2 are kept loose.
