The utility model is characterized in an eccentric and reliable connection element nail, which comprises a main nail and an eccentric nail, the main nail is provided with a nail rod and a nail cap, a nail tip is provided in the front end of the nail rod, the tail end of the nail rod is connected with a nail cap, and the side wall of the nail rod is provided with a side slot extending from the nail cap to the nail tip direction. The front end of the slot is connected with an oblique hole through the nail rod. The lower end position of the inclined hole is close to the nail tip in the front of the side slot. The axis of the oblique hole is intersected with the axis of the side slot and both are more than one hundred and thirty-five degrees. The eccentric nail has a guide rod that is in line with the side groove, which is penetrated by the vertical hole. The front end of the guide rod is connected with the cross section of the guide bar smaller than the cross section of the guide rod. On the side of the side of the side slot, there is a skew tip at the front end of the position bar, and the tip of the inclined tip is on the side of the side slot. The length of the eccentric nail is more than the sum of the side slot and the length of the oblique hole; both the main nail and the eccentric nail are not easy to pull off, and the connection is strong and easy to be processed.

一种偏心式可靠连接元钉
本技术涉及一种用于木材可靠连接的装置,特别是涉及一种偏心式可靠连接元钉。
技术介绍
在生产建设木材结合连接中元钉作为五金连接件经常用到,现有元钉都是实心单杆,使用时笔直插入两连接木材中,使两木材连接在一起,由于钉尖一侧木材钉杆直插进入,受力很容易拔脱出来,连接可靠性低,如何利用元钉实现可靠连接仍有待于技术解决。
技术实现思路
为了解决上述问题,本技术提供了一种偏心式可靠连接元钉。本技术采用的技术方案为:一种偏心式可靠连接元钉,其特征在于包括主钉和偏心钉,主钉设有钉杆和钉帽,钉杆前端设有钉尖,钉杆尾端与钉帽连接,钉杆侧壁设有由钉帽外向钉尖方向伸展的侧槽,钉帽上设有与侧槽相对的竖孔,侧槽前端连接有一贯穿钉杆的斜孔,斜孔下端位置比侧槽前端靠近钉尖,斜孔轴线与侧槽轴线相交且两者呈大于一百三十五度夹角,偏心钉设有一由竖孔穿入的与侧槽吻合的导杆,导杆前端连接有横截面面积比导杆横截面面积小的靠在侧槽内侧的定位杆,定位杆前端设有斜尖,斜尖尖端靠在侧槽内侧,偏心钉长度大于侧槽与斜孔长度之和。进一步的,所述侧槽为C型槽或燕尾槽。进一步的,所述导杆和定位杆为同材质一体连接。进一步的,所述导杆和定位杆为异材质一体连接,导杆硬度大于定位杆硬度。进一步的,所述侧槽前端距离钉尖的距离为钉杆长度的二分之一至四分之一之间。进一步的,所述竖孔在钉帽边沿设有豁口。进一步的,所述导杆和侧槽上分别设有配合滑槽和凸起。本技术用于上下两木材之间的连接,使用时先将主钉钉入需要连接两木材中,然后偏心钉的定位杆和斜尖朝向侧槽内侧插入竖孔,然后用锤敲击在斜尖导向作用下挤入侧槽,使定位杆的斜尖与 ...
