Abstract
The utility model discloses a stable combined piston rod electroplating thread connection device which comprises a joint. An external thread is arranged at the upper end of the joint, and an insert slot and a thread hole which are respectively used for insertion and thread connection of the end of the piston rod are arranged at the lower end of the joint. The thread hole is formed of multiple stages of step holes, the diameters of the step holes are reduced gradually from bottom to top, matching positioning rings are respectively arranged on the inner walls of the step holes except the step hole with smallest diameter, and outer walls of the positioning rings are detachably connected with the inner walls of the corresponding step holes, while inner walls of the positioning rings are flush with the inner wall of the step hole with the smallest diameter. The stable combined piston rod electroplating thread connection device is adaptable to piston rods different in outer diameter and length. Since the matching positioning rings which are respectively arranged on the inner walls of the step holes except the step hole with the smallest diameter can retain and fix the piston rods, problems of insufficient connection and swaying and the like can be avoided.
Description
Technical field
Coupling device when the utility model relates to a kind of piston rod electroplating frock relates in particular to a kind of stable combination piston bar threaded connection device for electroplating.
Background technology
Add man-hour in the plating of vehicular shock absorber component of rod category, its piston rod electroplating frock is to utilize its screw connection conduction, because the piston rod thread of different varieties varies in size, length is different, need the different conductive contact of the many covers of design to realize electroplating, so knockdown threaded connection device for electroplating occurred, this knockdown threaded connection device for electroplating inside is provided with the different hole of a plurality of diameters, connect respectively different sizes, the piston rod of length, and the hole of diameter minimum is positioned at penetralia, so just there is a problem, when the less piston rod of connection diameter, piston rod is a bit of to be connected with coupling device is inner, and all the other positions are unsettled, make the junction easily occur connecting unreal, the problem such as rock.
Summary of the invention
The purpose of this utility model just is that providing a kind of addresses the above problem, and is fit to the piston rod of a plurality of sizes, and connects the stable combination piston bar threaded connection device for electroplating of can be in fact, rocking.
To achieve these goals, the technical solution adopted in the utility model is such: a kind of stable combination piston bar threaded connection device for electroplating, comprise joint, upper end of joint is provided with outside screw, the lower end is provided with patchhole and the threaded hole that inserts and be threaded for the piston rod end, described threaded hole is made of the multi-stage stairs hole, described stepped hole from top to bottom diameter reduces successively, except the stepped hole of diameter minimum, all the other stepped hole inwalls are equipped with the retaining ring of coupling, described retaining ring outer wall removably connects with corresponding stepped hole inwall, and inwall is concordant with the stepped hole inwall of diameter minimum.
As preferably: described threaded hole is made of three grades of stepped holes, and is respectively from top to bottom one-level stepped hole, two stage steps hole and three grades of stepped holes.
As preferably: described joint and the coaxial setting of threaded hole.
Compared with prior art, the utility model has the advantage of: threaded hole is designed to be made of the multi-stage stairs hole, be fit to the various outer diameter size, the piston rod of different length, stepped hole from top to bottom diameter reduces successively, can not influence each other, and reduced the manufacturing cost of frock, not only saving of labor but also save time, enhance productivity, simultaneously greatly reduce again cost of manufacture, and except the stepped hole of diameter minimum, all the other stepped hole inwalls are equipped with the retaining ring of coupling, the retaining ring outer wall removably connects with corresponding stepped hole inwall, inwall is concordant with the stepped hole inwall of diameter minimum, when inserting the less piston rod of diameter, connects retaining ring, retaining ring is had to be held, the effect of firm piston rod, can not produce and virtually connect, the problem such as rock, use this device versatility good, install, it is all comparatively convenient to dismantle, effect is remarkable, has to promote widely practical value.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation that disassembles retaining ring among Fig. 1.
Among the figure: 1, joint; 2, patchhole; 3, one-level stepped hole; 4, two stage steps hole; 5, three grades of stepped holes; 6, retaining ring.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment 1: referring to Fig. 1, Fig. 2, a kind of stable combination piston bar threaded connection device for electroplating, comprise joint 1, joint 1 upper end is provided with outside screw, the lower end is provided with patchhole 2 and the threaded hole that inserts and be threaded for the piston rod end, described threaded hole is made of the multi-stage stairs hole, described stepped hole from top to bottom diameter reduces successively, except the stepped hole of diameter minimum, all the other stepped hole inwalls are equipped with the retaining ring 6 of coupling, described retaining ring 6 outer walls removably connect with corresponding stepped hole inwall, inwall is concordant with the stepped hole inwall of diameter minimum, described threaded hole is made of three grades of stepped holes 5, and is respectively from top to bottom one-level stepped hole 3, two stage steps hole 4 and three grades of stepped holes 5, described joint 1 and the coaxial setting of threaded hole.
Threaded hole is designed to be made of the multi-stage stairs hole, be fit to the various outer diameter size, the piston rod of different length, stepped hole from top to bottom diameter reduces successively, can not influence each other, and reduced the manufacturing cost of frock, not only saving of labor but also save time, enhance productivity, greatly reduce again simultaneously cost of manufacture, and except the stepped hole of diameter minimum, all the other stepped hole inwalls are equipped with the retaining ring 6 of coupling, and retaining ring 6 outer walls removably connect with corresponding stepped hole inwall, and inwall is concordant with the stepped hole inwall of diameter minimum, when inserting the less piston rod of diameter, connect retaining ring 6, retaining ring 6 is had hold, the effect of firm piston rod can not produce and virtually connects, the problem such as rock.
