This utility model is achieved through the following technical solutions: the latch torsional forces assay device of a kind of plug, including a base, the upper end of described base is provided with a horizontal ruler, the adjustable jury strut of side rational height of described horizontal ruler, arranging a support seat on the opposite side base of described jury strut, the upper end activity of described support seat arranges one for hanging up the arm of force of counterweight；The other end of the described arm of force arranges a gimbal lever, it is provided with balance weight in the described gimbal lever, arranging a rotary balance axle in the middle of the described arm of force, a latch auxiliary clamp is installed in the outboard end activity of described rotary balance axle, and the upper end of described jury strut offsets with the lower surface of the arm of force.
As preferred technical scheme, described latch auxiliary clamp cylindrical form, one end of latch auxiliary clamp is offered a fixture and is installed screwed hole, described rotary balance axle and fixture are installed screwed hole and are connected, the other end of described latch auxiliary clamp arranges an implant test hole, and the single latch of tested plug is inserted in implant test hole.
As preferred technical scheme, the side in described implant test hole arranges a latch fixing screw hole, arranges a latch and fix screw in described latch fixing screw hole, and the single latch of tested plug fixes screw lock by latch.
As preferred technical scheme, described arm of force upper surface is provided with more than one groove, the arm of force hangs up counterweight, and counterweight hangs up in arm of force upper recess.
The beneficial effects of the utility model are: the 1) test instrunment of not similar two functions of latch torsional forces having gathered plug torsional forces and plug in current each equipment supplier and testing laboratory, the ingenious function being effectively improved existing test instrunment of this patent formula, widen this Instrumentation Operating Areas, save lab resources；
2) circular hole of this auxiliary device is suitable for the torsional moment test of round pin of countries in the world plug, it is only necessary to the shape of suitably modified pin hole just may be used for the latch torsional moment test of other plug shape, has extremely strong Universal and scalability；
3) this latch auxiliary clamp principle is simple, easily manufactures installation, low cost, and test operation simple.
Accompanying drawing explanation
In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in describing below is only embodiments more of the present utility model, for those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is overall structure schematic diagram of the present utility model；
Fig. 2 is the scheme of installation of latch auxiliary clamp of the present utility model and rotary balance axle.
Detailed description of the invention
All features disclosed in this specification, or disclosed all methods or during step, in addition to mutually exclusive feature and/or step, all can combine by any way.
Any feature disclosed in this specification (including any accessory claim, summary and accompanying drawing), unless specifically stated otherwise, all can be by other equivalences or there is the alternative features of similar purpose replaced.I.e., unless specifically stated otherwise, an example during each feature is a series of equivalence or similar characteristics.
As shown in Figure 1, the latch torsional forces assay device of a kind of plug of the present utility model, including a base 8, the upper end of described base 8 is provided with a horizontal ruler 2, the adjustable jury strut of side rational height 1 of described horizontal ruler 2, arranging a support seat 7 on the opposite side base of described jury strut 1, the upper end activity of described support seat 7 arranges one for hanging up the arm of force 3 of counterweight；The other end of the described arm of force 3 arranges a gimbal lever 6, it is provided with balance weight 5 in the described gimbal lever 6, arranging a rotary balance axle 9 in the middle of the described arm of force 3, a latch auxiliary clamp 12 is installed in the outboard end activity of described rotary balance axle 9, and the upper end of described jury strut 1 offsets with the lower surface of the arm of force 3.
As shown in Figure 2, latch auxiliary clamp 12 cylindrical form, one end of latch auxiliary clamp 12 is offered a fixture and is installed screwed hole 10, described rotary balance axle 9 and fixture are installed screwed hole 10 and are connected, the other end of described latch auxiliary clamp arranges an implant test hole 4, and the single latch of tested plug is inserted in implant test hole 4.
The side in implant test hole arranges a latch fixing screw hole, arranges a latch and fix screw 11 in described latch fixing screw hole, and the single latch of tested plug is fixed screw 11 by latch and locked.
The arm of force 3 upper surface is provided with more than one groove, and the arm of force 3 hangs up counterweight, and counterweight hangs up in arm of force upper recess.
At the auxiliary clamp increasing a latch on the rotary balance axle of existing plug torsional forces tester, just may be used for the torsional forces of the single latch of test plug, the most original plug torsion-testing apparatus increases the torsional forces test function of the single latch of plug.
Before test, (1) first adjustment block makes the arm of force be in level, (2) then calculate according to the weight of counterweight used and meet the arm of force of the test torque value that standard specifies, and counterweight is hung over this arm of force point, (3) the single latch of tested plug is inserted the test hole of latch auxiliary clamp, and be screwed latch and make it not rotate, (4) power contrary with counterweight force direction is applied to plug, if the arm of force hanging counterweight is promoted to horizontal level, latch does not the most rotate, then think the torsional moment test requirement that latch conformance with standard specifies, if latch begins to have rotated before the arm of force hanging counterweight is promoted to horizontal level, then explanation latch can not meet the torsional moment test of standard gauge provisioning request.
The beneficial effects of the utility model are: the 1) test instrunment of not similar two functions of latch torsional forces having gathered plug torsional forces and plug in current each equipment supplier and testing laboratory, the ingenious function being effectively improved existing test instrunment of this patent formula, widen this Instrumentation Operating Areas, save lab resources；
2) circular hole of this auxiliary device is suitable for the torsional moment test of round pin of countries in the world plug, it is only necessary to the shape of suitably modified pin hole just may be used for the latch torsional moment test of other plug shape, has extremely strong Universal and scalability；
