Embodiment
As shown in Figures 1 to 12,
A kind of disconnecting link closes a floodgate and operates a switch assistor, has connecting portion 6 and operate portions,
Operate portions is the rectangular block 1 of a stainless steel, and on rectangular block 1, mill out a C connected in star 11, two arc-shaped slots 12 are formed by the mode removing entity in the two sides of C connected in star 11, two quadrant blocks 2 are slidably matched with C connected in star 11 by the arc-shaped slot 12 of both sides, be arc buckle 22 in quadrant block 2 both sides, and between rectangular block 1 and quadrant block 2, be provided with the first preloading spring 31, first preloading spring 31 is arranged in arc-shaped slot 12 and both ends of the spring contacts with quadrant block 2 with rectangular block 1 respectively, form preliminary pretension, it is a pretension back-moving spring.Wherein quadrant block 2 internal diameter size identical with the connecting rod diameter in disconnecting link, good cooperation can be realized like this.
The rectangular block 1 of C connected in star 11 centre is provided with one second spring mountings 13, and by the second spring 32, a wedge 4 is installed in the second spring mountings, in order to coordinate the installation of spring, second spring mountings 13 bottom is circular hole, the first half side of being taper hole shape, wedge-shaped indentation 21 is provided with at the corresponding position of quadrant block 2, such wedge 4 both sides and quadrant block 2 carry out wedge-like engagement 41, easy understand, by the motion of wedge 4, two quadrant blocks 2 are synchronous to two Slideslips in C connected in star 11, have two kinds of extreme positions:
As Fig. 5, when wedge 4 is positioned at peak, two quadrant blocks 2 form the semi arch that is less than or equal to 90 degree; For initial condition, connecting rod carry out very easily card and.
As Fig. 6, when wedge 4 is positioned at minimum point, two quadrant blocks 2 form the major arc that is greater than 90 degree, are operating state, and this is because quadrant block 2 tightly can embrace connecting rod, prevents connecting rod from coming off in groove.
Also comprise a pull bar 5, pull bar 5 one end is articulated in rectangular block 1 side by rotating shaft 51, for improving the compactness of instrument, the rectangular block 1 folding position at pull bar 5 establishes a square groove 14, make pull bar 5 folded state more hidden, and the other end of pull bar 5 is provided with second groove 52 contrary with C connected in star 11 opening, use during for operating a switch; Described pull bar 5 has folding and launches two states, is respectively used to close a floodgate and two kinds of working conditions of operating a switch.
The top of existing insulating bar 7 is mostly internal thread, and connecting portion 6 is designed to screw thread, and connecting portion 6 is threaded with insulating bar 7.
Use procedure is as follows:
Combined floodgate work: first pull bar 5 is broken folded state, and whole device is screwed at the top of insulating bar 7, with reference to Figure 12, then the connecting rod of disconnecting link is aimed at C connected in star 11 position by hand-held insulating bar 7, firmly under top, connecting rod contacts with wedge 4 gradually, continues firmly, connecting rod compressing wedge 4 moves down, in wedge 4 folding process, wedge 4 promotes quadrant block 2 to two Slideslips, in the process of sliding, gradually embrace connecting rod, until wedge 4 arrives minimum point.After combined floodgate puts in place, remove external force, quadrant block 2, wedge 4 automatically reset.
To operate a switch work: with reference to figure 4, first pull bar 5 is broken deployed condition, catch on connecting rod with the second groove 52 on pull bar 5, pull at down.
As another one embodiment,
Top for existing insulating bar 7 is the present situation of fast connecting fastener, and connecting portion is designed to buckle structure, and connecting portion carries out fast fastening with insulating bar 7 and is connected.
Be simplified design in addition, pull bar 5 be directly vertically fixed on rectangular block 1 side, and the other end of pull bar 5 is provided with second groove 52 contrary with C connected in star 11 opening, can play the function of operating a switch equally.
