Abstract
The utility model relates to a control lever for testing the service life of a switch. The control lever mainly comprises a reciprocating movement device, a reciprocating movement rod extends from one side of the reciprocating movement device, and the head of the reciprocating movement rod is connected with the control lever. The control lever is characterized in that the control lever comprises a base, a screw rod, an idler wheel and a pin shaft; one side of the base is forked and divided into two support plates; a U-shaped through hole is arranged in the middle of the two support plates; the through hole is internally provided with a slide block, and a reciprocating mechanism is arranged above the slide block; the screw rod is disposed at the other side of the base; the idler wheel is arranged in the forked support plate at one side of the base; and the slide block and the idler wheel are connected in series by the pin shaft and are arranged in each support plate. When the control lever is used for testing the service life of the switch, the switch drives the control lever to horizontally move in a reciprocating way, the idler wheel can be supported by a pressure spring to move up and down, and the idler wheel is wholly contacted with the surface of the switch, so that the test accuracy is improved.
Description
Technical field
The utility model relates to a kind of Test Switchboard life-span device, especially relates to a kind of operating rod that improves test accuracy.
Background technology
At present, being applied to test the equipment body in seesaw type power switch life-span is a reciprocator, head at reciprocator one lateral movement bar is equipped with an operating rod, as shown in Figure 7, existing operating rod is mainly by roller 8, bearing pin 9 and connecting rod 10 are formed, roller 8 directly is fixed on an end of connecting rod 10 by bearing pin 9, this device connects the rolling of directly roller 8 being fixed on the horizontal direction, when test, as shown in Figure 8, connecting rod 10 along continuous straight runs move forward and backward, from three actions of same switch, the one, disconnect, at this moment the operating rod on the left side, along with operating rod moved right position two during to position three, switch conduction.The operating rod back moves from three mistakes two to the position for the moment, and switch disconnects once more, finishes a working cycle.Supreme mobile down when horizontal direction moves back and forth, cause roller 8 and switch 11 surfaces can't in test process, reach full contact condition, be easy to cause switch motion to slip up as the position debugging is inaccurate.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of operating rod that improves test accuracy.
The technical scheme in the invention for solving the technical problem is: a kind of operating rod that is used for the Test Switchboard life-span, main body is a reciprocator, side at reciprocator is extended a reciprocating movement rod, head at reciprocating movement rod connects operating rod, and described operating rod comprises a pedestal, screw rod, roller and bearing pin; One side of described pedestal is forked, is divided into two support plates; Offer U type through hole in the centre of support plate; Be provided with slide block in the through hole, the top of slide block is provided with a reciprocator; Described screw rod is arranged on the opposite side of pedestal; Described roller is placed in the inside of the forked support plate of pedestal one side; Described bearing pin strings slide block and roller and is placed in the support plate.
In order to make roller can produce the state that moves up and down when testing, described reciprocator mainly comprises fore-set, stage clip and the screw that is successively set on the slide block top; Stage clip is pushed down fore-set, and screw retention is at the upper surface of support plate, and the screw lower end compresses stage clip.Described slide block cooperates through hole to be set to the U type, slides up and down along through-hole wall.
For operating rod is fastenedly connected on the movable connecting rod, be equipped with a nut on the described screw rod.
The beneficial effects of the utility model are: add a reciprocator on pedestal, slide block moves up and down, and gives roller by bearing pin transmitting movement state, drive moving up and down of roller, when test, guaranteed that roller contacts with the complete of switch upper surface, has improved test accuracy.

Embodiment
Fig. 1～shown in Figure 5 is a kind of to be used for the operating rod in Test Switchboard life-span, main body is a reciprocator, side at reciprocator is extended a reciprocating movement rod, head at reciprocating movement rod connects operating rod, and it is characterized in that: described operating rod comprises a pedestal 5, screw rod 6, roller 8 and bearing pin 9; One side of described pedestal 5 is forked, is divided into two support plate 5-1; Offer U type through hole 5-2 in the centre of support plate 5-1; Be provided with slide block 4 in the through hole 5-2, the top of slide block 4 is provided with a reciprocator; Described screw rod 6 is arranged on the opposite side of pedestal 5; Described roller 8 is placed in the inside of the forked support plate of pedestal 5 one sides; Described bearing pin 9 strings slide block 4 and roller 8 and is placed in the support plate 5-1.: be equipped with a nut 7 on the described screw rod 6, effect is that operating rod is fastenedly connected on the movable connecting rod.
Fig. 4, reciprocator shown in Figure 5 mainly comprise fore-set 3, stage clip 2 and the screw 1 that is successively set on slide block 4 tops; Stage clip 2 is pushed down fore-set 3, and screw 1 is fixed on the upper surface of support plate 5-1, and screw 1 lower end compresses stage clip 2; Slide block 4 cooperates through hole 5-2 to be set to the U type, slides up and down along through hole 5-2 inwall.By slide block 4 slidably, drive roller 8 and when test, can produce the state that moves up and down.
Screw rod 6 along continuous straight runs shown in Figure 6 move forward and backward, from three actions of same switch, the one, disconnect, this moment the operating rod on the left side, along with operating rod moved right position two during to position three, switch conduction.The operating rod back moves from three mistakes two to the position for the moment, and switch disconnects once more, finishes a working cycle.The reciprocator that adds on the pedestal 5, slide block 4 moves up and down, and gives roller 8 by bearing pin 9 transmitting movement states, drives moving up and down of roller 8, when test, has guaranteed complete the contacting of roller 8 with switch 11 upper surfaces, has improved test accuracy.
