A branch type reliable connection pin

The utility model is characterized in a core nail and a main nail. The main nail is provided with a nail rod and a nail cap. The nail rod is divided into two sections of the front section of the nail rod and the rear section of the nail rod. The front end of the nail rod is provided with a nail tip. The front section of the nail rod is provided with at least two nails on the round hole nail tip from the rear to the nail tip. The axis of the rod is a penetrating hole with a circumferential equidistant distribution. The axis of the perforation is a circular hole with a thirty to 45 degree angle with the axis of the nail bar. The upper end of the perforation is open to the bottom of the circular hole, and the bottom of the perforation is open to the cone surface. The core has a vertical core that corresponds to the upper end of the perforation, and the bottom of the core has a cone tip. The core is equipped with a cone tip. The upper end of the rod is connected with the core cap that fits in the hole. The rear end of the nail rod is connected with the nail cap. The rear section of the nail rod has a core hole that runs back through the nail. The front end of the nail rod is equipped with a ring convex platform which is pressed on the core cap through the thread and the rear end of the nail rod; it is not easy to pull off and connect firmly.

【技术实现步骤摘要】
一种分头式可靠连接元钉
本技术涉及一种用于木材可靠连接的装置，特别是涉及一种分头式可靠连接元钉。
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，本技术提供了一种分头式可靠连接元钉。本技术采用的技术方案为：一种分头式可靠连接元钉，其特征在于包括芯钉和主钉，主钉设有钉杆和钉帽，钉杆分为钉杆前段和钉杆后段两段，钉杆前段前端设有钉尖，钉杆前段轴心位置设有由后向前至钉尖部位的圆孔，钉尖上设有至少两个以钉杆轴线为轴周向等距分布的贯穿孔，贯穿孔为圆孔其轴线与钉杆前段轴线呈三十至45度夹角，贯穿孔上端开放至圆孔底部，贯穿孔下端开放至钉尖锥面上，芯钉设有与各贯穿孔上端一一对应的竖向芯杆，芯杆下端设有锥形尖，芯杆上端连接有吻合在圆孔内的芯帽，钉杆后段尾端与钉帽连接，钉杆后段设有向后贯穿钉帽的芯孔，钉杆后段的前端设有通过螺纹与钉杆前段后端连接的压在芯帽上的环形凸台。进一步的，所述贯穿孔为三个本文档来自技高网...
