The invention discloses a connecting structure of a front forklift head tube, a lower steel bowl and a lower stopper and a manufacturing process, the connecting structure comprises the front forklift head tube, the lower steel bowl, a lower bearing and the lower stopper, the front forklift head tube is connected with the lower steel bowl, the lower bearing is arranged in the lower steel bowl, the lower stopper is arranged below the lower bearing, the lower steel bowl is provided with a tube head, a bearing seat and a step, and the step is connected with the lower steel bowl. The front fork truck head tube is characterized in that 1-N convex blocks are arranged on a round opening at one end of the front fork truck head tube; 1-N notches are formed in the tube head of the lower steel bowl; two convex clamping sheets are arranged outside the opening plane of the lower steel bowl bearing seat; the front fork truck vertical pipe connecting structure has the advantages that the protruding blocks are completely inserted into the notches, so that the front fork truck vertical pipe is in fixed connection with the lower steel bowl, the plane displacement phenomenon is avoided, and the relative position of the handle and the front wheel is always kept in the original state; the convex clamping piece of the lower steel bowl and the convex blocking piece of the lower blocking piece are located on the same plane, so that the rotating direction of the front wheel is limited within a certain rotating angle range.

    本发明公开了一种前叉车头管与下钢碗和下档的连接结构和制造工艺,由前叉车头管、下钢碗、下轴承和下档组成,前叉车头管与下钢碗连接,下钢碗内有下轴承,下轴承下有下档,所述的下钢碗有管头、轴承座和台阶,其特征在于:所述的前叉车头管的一端圆口上有1∽N个凸块;所述下钢碗的管头有1∽N个缺口;下钢碗轴承座的口平面外有2个凸卡片;所述的下档的底盘圆周外有2个凸档片,所述的凸块、缺口、和凸卡片用冲压工艺完成的,有益效果是:所述的凸块完全插入缺口内,使前叉车立管与下钢碗成为死连接,不会出现平面位移现象,始终保持把手与前车轮相对位置的原状;所述的下钢碗的凸卡片和下档的凸挡片在同一平面上,使前轮转动方向被限制在一定转角范围。
