Example one

Referring to fig. 1-3, an anti-drop indoor high-voltage grounding switch includes a cabinet 1, a control rod 2, a sliding rod 3, and an anti-loose mechanism disposed on a side surface of the cabinet 1, wherein the control rod 2 is rotatably connected to an inner wall of the cabinet 1, and the anti-loose mechanism includes a transmission assembly and a limit assembly;

the transmission assembly comprises a rotary disc 4, a connecting plate 5, a connecting rod 6 and a sliding block 7, the rotary disc 4 is rotatably connected to the inner wall of the cabinet body 1, the connecting plate 5 is rotatably connected to the surface of the rotary disc 4, the connecting rod 6 is rotatably connected to the surface of the connecting plate 5, and the sliding block 7 is fixedly connected to the bottom of the connecting rod 6;

the limiting assembly comprises a movable plate 8, an embedded rod 9, a transmission plate 10 and a limiting ring 11, the movable plate 8 is rotatably connected to the surface of the sliding block 7, the embedded rod 9 is fixedly connected to the surface of the movable plate 8, the transmission plate 10 is slidably connected to the surface of the embedded rod 9, and the limiting ring 11 is fixedly connected to the surface of the transmission plate 10.

Furthermore, two groups of connecting joint plates 5 are symmetrically arranged around the circle center of the rotary table 4, and the two groups of connecting joint plates 5 are arranged on the central axis of the rotary table 4; rotating the rotary disc 4, the rotary disc 4 can apply tension to the two groups of connecting plates 5 to the circle center of the rotary disc, so that the rotary disc drives the connecting rods 6 and the sliding blocks 7 to be close to the central point of the cabinet body 1.

Furthermore, the connection points of the connection plates 5 and the connection rods 6 are positioned at the end points of the connection plates, and two groups of V-shaped movable plates 8 are symmetrically arranged on the central axis of the sliding block 7; by providing the movable plates 8, when the angles of the two sets of movable plates 8 change, the driving plate 10 is driven to slide along the cabinet 1.

Further, the embedded rod 9 and the movable plate 8 are arranged vertically to each other; because the two sets of movable plates 8 are arranged in a V shape, when the slider 7 moves, the two sets of movable plates 8 are driven to open, and the embedded rod 9 is driven to slide along the surface of the transmission plate 10, and then the transmission plate 10 drives the limiting ring 11 to be out of contact with the sliding rod 3.

Furthermore, the surface of the limiting ring 11 is provided with a slideway matched with the slide rod 3, and the slide rod 3 is embedded into the slideway on the surface of the limiting ring 11 and is connected with the slideway in a sliding way; through the slide way arrangement on the surface of the limiting ring 11, the sliding rod 3 slides on the inner wall of the sliding rod, the limiting effect is realized, and the control rod 2 is prevented from loosening.

Example two

Referring to fig. 1-4, in a first comparative embodiment, as another embodiment of the present invention, a movable rod 12 is slidably connected to an inner wall of a cabinet 1, a nut 13 is engaged with a surface of the movable rod 12, a control board 14 is fixedly connected to a rear portion of the movable rod 12, a fixed board 15 is slidably connected to a surface of the control board 14, and a contact 16 is embedded in an inner wall of the cabinet 1 at a bottom of the fixed board 15.

Furthermore, the surface of the fixed plate 15 is provided with a chute which is obliquely arranged, and the fixed plate 15 forms a lifting structure through the control panel 14; since the control plate 14 is embedded inside the inclined groove on the surface of the fixed plate 15, when the control plate 14 is moved to the left, the fixed plate 15 is caused to move upward.

Furthermore, concave holes matched with the size of a convex plate at the bottom of the fixed plate 15 are formed in the surface of the contact 16; by providing the recess, the fixing plate 15 can be easily inserted into the recess to fix the contact 16 and prevent the contact from being loosened.

Working principle, during the use, through setting up spacing ring 11, can make control lever 2 when rotatory, drive the slide bar 3 with self fixed connection and remove in the inside of spacing ring 11, block in the inside of spacing ring 11 through slide bar 3 card, can prevent when control lever 2 frequently rotates and contact 16 contacts, the problem that leads to the pine of control lever 2 to take off, when needing to take off spacing ring 11 from slide bar 3, rotatory carousel 4, carousel 4 can exert pulling force to the centre of a circle of oneself to two sets of linkage plate 5, make it drive linkage rod 6 and slider 7 draw close to the central point of the cabinet body 1, because two sets of fly leaf 8 are "V" shape setting, when slider 7 removes, can drive two sets of fly leaf 8 and open, and drive embedded bar 9 along the surperficial slip of driving plate 10, drive plate 10 can drive spacing ring 11 and slide bar 3 break away from the contact afterwards.

Because the contact 16 is embedded in the cabinet 1, when the bottom of the fixing plate 15 is clamped on the surface of the contact 16, the contact 16 is fixed to prevent the contact 16 from being loosened, when the contact 16 needs to be replaced, only the moving rod 12 needs to be slid along the cabinet 1, and the control plate 14 moves along with the moving rod, because the control plate 14 is embedded in the inclined groove on the surface of the fixing plate 15, when the control plate 14 moves to the left side, the fixing plate 15 can be moved upwards and separated from the contact of the contact 16, and the purpose of detaching the contact is achieved.
