Background

There are many electrically operated mechanisms with remote operation function installed on electrical switches on the market today. The remote control switch has the function of remotely operating the electrical switch across the region, so that the power distribution system has complete functions. The electric operating mechanism with the remote operation function can meet the electric operation generally and can also meet the manual operation function in states of maintenance emergency and the like, so that the situation that when power is applied manually, the power is not transmitted to the electric power component reversely by the transmission mechanism and is moved in a reverse transmission ratio to damage the power component must be considered.

The traditional operating mechanism generally only adopts a ratchet mode to realize the clutch effect: the electric power is positively transmitted to drive a single direction to transmit power torque; manual power reverse motion, the ratchet skids, can not transmit manual power to electronic to realize manual and electronic each other's separation and reunion effect, but do not push down in place among the current structure and also can rotate the handle and realize manual divide-shut brake, the pressure can not the position appear easily, the separation and reunion does not break away from just rotating handle, the separation and reunion damage with higher speed.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an aim at do not push down in the structure to above-mentioned current and put in place also can the twist grip realize manual divide-shut brake, it can not the position to appear pressing easily, the separation and reunion does not break away from and damages clutch mechanism's technical defect with twist grip, a structure of clutch mechanism reliability that improves electrical switch remote operation mechanism is provided, increase separation and reunion stop gear, only push down completely when the boss of handle stops below the part, the handle just can rotate, otherwise can be blockked by the locating part, can not rotate, and then obtain the operating handle and must push down and put in place, the separation and reunion must separate completely just can the twist grip's effect.

Technical scheme

In order to realize the technical purpose, the utility model provides an improve structure of electrical switch remote operation mechanism's clutching mechanism reliability, including handle, power shaft, main support and clutch spare, the handle inserts the power shaft can drive the power shaft rotates simultaneously the handle downstream in-process can drive power shaft downstream with the clutch spare separation, its characterized in that: the clutch limiting structure is arranged between the limiting part and the handle and can limit the downward movement of the power shaft and the separation process of the clutch part to only move in the vertical direction but not rotate.

Furthermore, separation and reunion limit structure includes the boss on the handle, be equipped with on the locating part with the spacing hole that the boss corresponds, the boss is located can only move along vertical direction in the spacing hole.

Further, the height of the limiting hole is not less than the distance length of the downward movement of the power shaft and the separation of the power shaft and the clutch piece.

Further, the power shaft vertically penetrates through the first through hole in the main support and the second through hole in the limiting piece.

Further, the limiting piece is installed on the upper surface of the main support.

Furthermore, the limiting piece is a metal piece or a plastic piece.

Advantageous effects

The utility model provides a pair of improve structure of electrical switch remote operation mechanism's clutching mechanism reliability increases separation and reunion stop gear, only pushes down completely when the boss of handle blocks below the part, and the handle just can rotate, otherwise can be blockked by the locating part, can not rotate, and then obtains operating handle and must push down and target in place, and the separation and reunion must separate the effect that could the twist grip completely.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1, 2, 3 and 4, a structure for improving the reliability of a clutch mechanism of an electric switch remote operation mechanism comprises a handle 1, a power shaft 2, a main bracket 4 and a clutch piece 5, wherein a limiting piece 3 is arranged on the upper surface of the main bracket 4. The limiting piece 3 is a metal piece or a plastic piece. The handle 1 inserts power shaft 2 can drive power shaft 2 rotates simultaneously handle 1 downstream in-process can drive power shaft 2 downstream with separation of separation and reunion piece 5, wherein, be equipped with locating part 3 on the main support 4, locating part 3 with be equipped with separation and reunion limit structure between the handle 1 and can restrict power shaft 2 downstream with there is only vertical direction motion and can not rotate in the separation and reunion piece 5 separation process.

Specifically, as shown in fig. 5, the clutch limiting structure includes a boss 101 on the handle 1, a limiting hole 301 corresponding to the boss 101 is provided on the limiting member 3, and the boss 101 is located in the limiting hole 301 and can only move in the vertical direction. The power shaft 2 vertically penetrates through a first through hole 401 on the main support 4 and a second through hole 302 on the limiting piece 3. In order to ensure that the power shaft 2 and the clutch 5 cannot rotate in the separation process, the height of the limiting hole 301 is not less than the distance length of the downward movement of the power shaft 2 and the separation of the clutch 5.
