The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further illustrated.
As Fig. 1～shown in Figure 10, rod member joint of the present utility model comprises joint body 1, one end of joint body 1 is forked standard 2 or jaw 3, the other end of joint body 1 is tip side 4, tip side 4 is provided with the blind hole that is connected with the end of rod member 11 coupling as nipple orifice 5, be evenly equipped with at least two weld seam grooves 7,9 on the outer peripheral face of tip side 4, weld seam groove 7,9 the degree of depth reach to being communicated with nipple orifice 5.Rod member joint of the present utility model is mainly the structure that has increased nipple orifice 5 with respect to existing rod member joint, be used for holding, coordinating and connect the rod member termination that is complementary with it, thereby the operation of will be originally holing in the rod member termination is changed into and is carried out on the rod member joint, the relatively general rod member much shorter of length due to the rod member joint, process more convenient, simultaneously, can not weaken rod member intensity.
as Fig. 1～shown in Figure 10, the syndeton of the utility model rod member joint and rod member comprises the rod member joint 12 that at least one end of rod member 11 and described rod member 11 arranges, 13, rod member joint 12, 13 comprise joint body 1, one end of joint body 1 is forked standard 2 or jaw 3, the other end of joint body 1 is tip side 4, tip side 4 is provided with the blind hole that is connected with the end of rod member 11 coupling as nipple orifice 5, be evenly equipped with at least two weld seam grooves 7 on the outer peripheral face of tip side 4, 9, weld seam groove 7, 9 the degree of depth reaches to being communicated with nipple orifice 5, rod member 11 be plugged in described nipple orifice 5 and with described rod member joint 12, 13 at weld seam groove 7, 9 position full welds connect, and be provided with the ring plug weld seam 8 of arranging along the outer peripheral face of rod member 11 on tip side end face 6, thereby rod member 11 and rod member joint 12, be firmly connected to each other between 13, be not shifted.
After perforate on rod member joint 12,13, on rod member 11 just without perforate, thereby the intensity without detriment to rod member 11, because rod member joint 12,13 length dimension are shorter than rod member 11, processing weld seam groove and nipple orifice are more convenient on rod member joint 12,13, rod member joint 12,13 can check by size and guarantee its intensity, and simultaneously, rod member joint 12,13 can guarantee bonding strength by the optimization welding procedure with rod member 11 welding positions.
As Fig. 1～shown in Figure 10, preferred described weld seam groove 7,9 is straight trough, and its length direction is parallel with nipple orifice axis 50, is convenient to processing and welding.
As Fig. 1～shown in Figure 10, maintain distance between the cell wall of preferred described weld seam groove 7,9 close tip side end face 6 one sides and tip side end face 6, thereby avoid axial weld seam and girth seam to form the welding of T shape, reduce welding stress, improve the welding one-time success rate, reduce weld defect.
Be generally round cross section or square cross section according to rod member 11, corresponding nipple orifice 5 can be circular hole or square hole.When described nipple orifice 5 was square hole, usually designing weld seam groove 7,9 was four, and weld seam groove 7,9 is positioned at the position that the inscribed circle of nipple orifice 5 and nipple orifice 5 intersect, and after being convenient to control welding, nipple orifice axis 50 is as far as possible coaxial with center line of the bar.
Fig. 1～Figure 3 shows that an end is the rod member joint 12 of the connection forked standard formula of forked standard 2, Fig. 4～Figure 6 shows that an end is the rod member joint 13 of the yoke hair style of jaw 3.
