One end elasticity of extension slot 12, at this time elastomer block 13 by the lower wall of limit hole 14 limited will not to far from loose slot 11 one
Side is mobile, to realize the connection of fixed part 8 and movable part 9.
As shown in Figure 3, Figure 4, the upper inside walls of limit hole 14 are equipped with shifting chute 15, and the downside inner wall of limit hole 14 is equipped with solid
Determine slot 16.The upper inside walls of shifting chute 15 are fixed with spring 17, and the other end of spring 17 is fixed with to be interference fitted with fixing groove 16
Movable block 18, movable block 18 takes in shifting chute 15 under the action of spring 17.Side of the shifting chute 15 far from loose slot 11
Equipped with the through-hole 19 extended along the vertical direction, the mobile bar 20 being fixedly connected with movable block 18 is slidably equipped in through-hole 19.It splits solid
When determining portion 8 and movable part 9, mobile bar 20 is moved down along through-hole 19 so that movable block 18 is embedded in fixing groove 16, movable block 18 exists
Elastomer block 13 is gradually squeezed in mobile process and make elastomer block 13 withdraw elastic groove 12 in, at this time people can by movable part 9 to
Side far from fixed part 8 is mobile to separate the two.Spring 17 can drive movable block 18 to withdraw in shifting chute 15, to avoid
Movable block 18 stretches out shifting chute 15 and influences the movement of elastomer block 13.
As shown in Figure 1 and Figure 2, a rotation slot 21, the side of rotation slot 21 are respectively equipped on the left and right inner wall of fixation hole 7
Equipped with guide groove 22, the depth of guide groove 22 is gradually increased to the side far from rotation slot 21, and rotation slot 21 and guide groove 22 are equal
On movable part 9.The left and right end face of contact platform 3 is respectively fixed with a rotating block 23, and two rotating blocks 23 are located at
In two rotation slots 21, rotating block 23 is equipped with screw hole 24, and movable part 9 is equipped with connecting hole 25, be equipped in connecting hole 25 with
The bolt 26 that screw hole 24 is threadedly coupled.Rotating block 23 can be moved in guide groove 22 by people by guide groove 22, then by twisting
Tight bolt 26 fixes the position of contact platform 3.When stationary contact 6 and the movable contact that is mounted on the moving contact on shell there are still
When small difference, people can make the position of stationary contact 6 change by rotary contact platform 3 after unscrewing bolt 26, to make
People are not necessarily to dismount connector portions 1 again when finely tuning the position of stationary contact 6, easy to operate.
As shown in Figure 1 and Figure 2, uniformly there are six locating slot 27, the left and right ends of contact platform 3 for the external circumferential of rotation slot 21
Face is respectively equipped with a sliding groove 28, and the locating rod 29 being interference fitted with locating slot 27 is slidably equipped in sliding groove 28.Sliding groove 28
End face far from connector portions 1 is equipped with the passage slot 30 being connected to sliding groove 28, elapses to be slidably equipped in slot 30 and fix with locating rod 29
The pushing block 31 of connection.When people by the angular adjustment of contact platform 3 in place after, by pushing block 31 to close to locating slot 27 a sidesway
It moves, so that the insertion of locating rod 29 is in its similar locating slot 27, locating rod 29 and the interference fit of locating slot 27 play and tentatively determine
The effect of position contact platform 3, avoids people position of stationary contact 6 during turning bolt 26 from changing.
The working principle of the present embodiment: 26 are first loosered a bolt when people need to finely tune the position of stationary contact 6, then will be pushed away
Block 31 is mobile to the side of remotely located slot 27, so that locating rod 29 is separated with locating slot 27, then people can be touched by rotation
Point platform 3 makes its tilt angle change, and then the position of stationary contact 6 is made to change.When the position of stationary contact 6 is adjusted to
When can be abutted with the movable contact being mounted on shell, by pushing block 31 by the insertion of locating rod 29 with its similar in locating slot 27,
So that the position of contact platform 3 is tentatively fixed, then fix the position of stationary contact 6 by tightening bolt 26, so that people are micro-
It adjusts without dismounting connector portions 1 again when stationary contact 6, it is easy to operate.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel design concept, any modification, equivalent replacement, improvement and so on should be included in the protection of the utility model
Within the scope of.
