Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the B-B of Fig. 1 is to sectional view.
Embodiment
Below in conjunction with concrete drawings and Examples, the invention will be further described.
As shown in Fig. 1 ~ Fig. 2: the present invention includes reducer union 1, differential nut 2, leaded light extension tube 3, the first binding thread 4, the second binding thread 5, the 3rd binding thread 6, the 4th binding thread 7, nut positioning step 8, connect die nipple end 9, connection female coupling tap end 10, the 5th binding thread 11, joint location step 12 and light pipe connection glue groove 13.
As depicted in figs. 1 and 2: the differential linkage structure of the present invention comprise reducer union 1 and with the leaded light extension tube 3 of described reducer union 1 corresponding matching; One end of reducer union 1 forms and connects female coupling tap end 10, and the outer wall of the other end of reducer union 1 is provided with the 5th binding thread 11, and reducer union 1 can be fastenedly connected with refractive power elbow by the 5th binding thread 11; In reducer union 1, convex with joint location step 12, described joint location step 12 is in abutting connection with the 5th binding thread 11.The corresponding outer wall that forms connection female coupling tap end 10 of reducer union 1 is provided with the 3rd binding thread 6.
One end of leaded light extension tube 3 forms and connects die nipple end 9, and the corresponding one end caliber that forms connection die nipple end 9 of leaded light extension tube 3 becomes greatly gradually, forms required tapering; The outer wall of leaded light extension tube 3 is provided with the 4th binding thread 7, the four binding threads 7 in abutting connection with connecting die nipple end 9.The outer wall of leaded light extension tube 3 is provided with light pipe and connects glue groove 13, and light pipe connects glue groove 13 and distributes in the shape of a spiral in leaded light extension tube 3.
The reliability being connected with leaded light extension tube 3 in order to ensure reducer union 1, reducer union 1 is fastenedly connected with leaded light extension tube 3 by differential nut 2.Particularly, one end in differential nut 2 is provided with the first binding thread 4, the other end is provided with the second binding thread 5,5 of the first binding thread 4 and the second binding threads pass through nut positioning step 8 intervals, the first binding thread 4 can be connected with the 3rd binding thread 6 couplings, and the second binding thread 5 can be connected with the 4th binding thread 7 couplings.Leaded light extension tube 3 correspondences form the end of connection die nipple end 9 and stretch in differential nut 2, and after the second binding thread 5 corresponding matching by the 4th binding thread 7 and differential nut 2, realize being fastenedly connected of leaded light extension tube 3 and differential nut 2.After above-mentioned connection, differential nut 2 female guests are stretched into in the corresponding end that forms connection female coupling tap end 10 of reducer union 1 to be enclosed within on connection die nipple end 9, the tapering that connects die nipple end 9 matches with the tapering that is connected female coupling tap end 10, thereby can make leaded light extension tube 3 and reducer union 1 corresponding matching.Simultaneously, reducer union 1 can be fastenedly connected with the first binding thread 4 of differential nut 2 by the 3rd binding thread 6, thereby can make reducer union 1 and differential nut 2, leaded light extension tube 3 interconnect and be integral, and the axis of reducer union 1, differential nut 2 and leaded light extension tube 3 is located along the same line.
In differential nut 2, the pitch of the first binding thread 4 is twices of the second binding thread 5 pitch, can be when connecting die nipple end 9 insertion connection female coupling tap end 10, when the 3rd binding thread 6 and the first binding thread 4 corresponding matching impacts are connected 9 insertion of die nipple end, start to allow the 3rd binding thread 6 and the first binding thread 4 corresponding matching, when the 3rd binding thread 6 precession differential nuts 2 are passed through in reducer union 1, leaded light extension tube 3 outwards exits by the 4th binding thread 7, because the first binding thread 4 is different from the lead of screw thread of the second binding thread 5, when the 4th binding thread 7 outwards exits 1mm, reducer union 1 screws 2mm by the 3rd binding thread 6, thereby can be gradually by the cone tension of reducer union 1 and leaded light extension tube 3, until reducer union 1 is passed through differential nut 2 together with 3 complete combinations of leaded light extension tube, guaranteed reducer union 1, the concentricity of differential nut 2 and leaded light extension tube 3, circular runout is little, there is certain self-repair function, increased the surface of contact connecting axially, there is stronger connection rigidity, thereby can make light-conducting arm long-term stable operation, improve the performance of light-conducting arm.
