Detailed Description

Example 1:

referring to fig. 1, fig. 2, fig. 3 and fig. 4, the present invention provides a technical solution:

the utility model provides an electric automatization laboratory is with binding post, including binding post body 1 and set screw 2, the inside equal screwed connection of 1 up end of binding post body has set screw 2, the equal fixedly connected with pivot 5 of terminal surface before binding post body 1, the equal fixedly connected with torsion spring 6 in the 5 outside of pivot, the equal fixedly connected with baffle 3 of the 6 other ends of torsion spring, catching groove 4 has all been seted up to the terminal surface before baffle 3, the equal fixedly connected with fixed axle 8 in 3 rear end face left sides of baffle, the 8 outside of fixed axle all is equipped with expanding spring 9, the equal sliding connection of the 8 other ends of fixed axle has slider.

One end of an expansion spring 9 is fixedly connected with a baffle 3, the other end of the expansion spring 9 is slidably connected with a sliding block 7, the outer side of the sliding block 7 is slidably connected with the baffle 3, the arrangement of the expansion spring 9 ensures that the sliding block 7 slides out under the action of the expansion spring 9 and a fixed shaft 8 when the baffle 3 rotates, at the moment, the sliding block 7 can be contacted with a connecting terminal body 1 to realize a blocking effect and avoid resetting, and ensure normal use of the baffle 3, the left side of the sliding block 7 is arranged in an arc shape, the rear end surface of the sliding block 7 is level with the rear end surface of the baffle 3, the sliding block 7 is extruded, and is convenient to be accommodated into the baffle 3 due to the arc arrangement of the left side of the sliding block 7 to realize the accommodating work, the rear end surface of the baffle 3 is fixedly connected with clamping rings 10 which are distributed up and down, the clamping rings 10 are formed by, make its connecting wire neatly arranged, the connecting wire can be fixed to snap ring 10, even the connecting wire receives outside power of dragging, its connecting wire is difficult for separating with binding post, guarantee binding post normal use, 3 front sides of baffle and binding post body 1 preceding terminal surface parallel and level, 3 outsides of baffle and binding post body 1 block, this kind of setting guarantees binding post body 1's wholeness, baffle 3 plays and blocks the effect, avoid the foreign matter to get into inside, fine guard action has.
