Abstract
The invention discloses an electroplated threaded connection device of a stable combined piston rod. The electroplated threaded connection device comprises a connector, wherein an outer thread is arranged at the upper end of the connector; the lower end of the connector is provided with an inserting hole and a threaded hole, trough which the end part of the piston rod is inserted into and in threaded connection with the connector; the threaded hole is composed of a plurality of grades of step holes; the diameters of the step holes are reduced sequentially from bottom to top; matched positioning rings are arranged on the inner walls of the step holes except for the step hole with the smallest diameter; the outer walls of the positioning rings are detachably connected with the inner walls of the corresponding step holes; the inner walls of the positioning rings are leveled with the inner wall of the step hole with the smallest diameter. The electroplated threaded connection device of the stable combined piston rod is applicable to piston rods with different outer diameters and different lengths; the matched positioning rings are arranged on the inner walls of the step holes except for the step hole with the smallest diameter so as to have the effect of pulling and stabilizing the piston rods; problems of virtual connection, shaking and the like are not generated.
Description
Technical field
Coupling device while the present invention 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
At vehicular shock absorber component of rod category, electroplate and add man-hour, 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 plating, so there is knockdown threaded connection device for electroplating, 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, all the other positions are unsettled, make junction easily occur connecting unreal, the problem such as rock.
Summary of the invention
Object of the present invention is just that providing a kind of addresses the above problem, and is applicable 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 used in the present invention 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, lower end is provided with patchhole and the threaded hole that inserts and be threaded for piston rod end, described threaded hole consists of 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, inwall is concordant with the stepped hole inwall of diameter minimum.
As preferably: described threaded hole consists 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 threaded hole coaxially arrange.
Compared with prior art, the invention has the advantages that: threaded hole is designed to consist of multi-stage stairs hole, be applicable to 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 cost of manufacture simultaneously, and except the stepped hole of diameter minimum, all the other stepped hole inwalls are equipped with the retaining ring of coupling, 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, connect 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, dismounting all more for convenience, effect is remarkable, have and promote widely practical value.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 disassembles the structural representation of retaining ring in Fig. 1.
In 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
Below in conjunction with accompanying drawing, the invention will be further described.
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, lower end is provided with patchhole 2 and the threaded hole that inserts and be threaded for piston rod end, described threaded hole consists of 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 consists of three grades of stepped holes 5, and be 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 coaxially arranges with threaded hole.
Threaded hole is designed to consist of multi-stage stairs hole, be applicable to 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 cost of manufacture simultaneously, and except the stepped hole of diameter minimum, all the other stepped hole inwalls are equipped with the retaining ring 6 of coupling, retaining ring 6 outer walls removably connect with corresponding stepped hole inwall, 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 to be held, the effect of firm piston rod, can not produce and virtually connect, the problem such as rock.
Claims (3)
1. a stable combination piston bar threaded connection device for electroplating, comprise joint, upper end of joint is provided with outside screw, lower end is provided with patchhole and the threaded hole that inserts and be threaded for piston rod end, it is characterized in that: described threaded hole consists of 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.
