The pull rod of the pipe, one end of the pull rod is provided with a pull rope, the other end of the pull rod is provided with a pull hook, the pull rod is provided with a baffle located in the sleeve, and the sleeve is provided with a compression rod which is worn on the pull rod and located between the baffle and a blocking plate. spring.

The plane where the slot is located is perpendicular to the rotating shaft.

By adopting the above-mentioned technical scheme, the utility model is specially used for mounting a special phase sequence plate, which includes a phase sequence plate body inserted in a slot, and the upper end of the phase sequence plate body is riveted with a cross-section by rivets. The connecting plate is in the shape of an angle iron, and the edge of the horizontal section of the connecting plate is provided with a clamping mechanism.

The clamping mechanism includes a clamping plate connected to the lower surface of the connecting plate through a pin shaft, and a torsion spring located between the connecting plate and the clamping plate is passed through the pin shaft. The hook is connected to the lower surface of the connecting plate, and the clamping plate is provided with a hook matched with the draw hook.

When hanging the phase sequence card, place the phase sequence card body in the slot on the fixed plate, lift the lower end of the telescopic rod upwards, lift the connecting plate above the beam (angle iron) hanging the phase sequence card body, and then Pull the pull rope, the rotating shaft rotates around the fixed sleeve, one end of the pull hook of the pull rod rotates upwards to the hook, the pull hook is hooked to the hook, and the pull rope continues to pull, the pull rod overcomes the force of the compression spring and moves downward, and the pull hook at the upper end of the pull rod pulls the card through the hook. The plate overcomes the force of the torsion spring, the clamping plate opens downward, and the telescopic rod falls downward to make the connecting plate contact the upper surface of the beam, and then release the pull rope. Under the action of the torsion spring, the clamping plate is stuck on the lower surface of the beam. Then take down the telescopic rod to complete the work of the electrified phase sequence plate.

The utility model has a simple structure and a reasonable design, and is specially suitable for mounting the special phase sequence plate on the beam in the shape of an angle iron. The phase sequence plate can be mounted under the condition of not pulling the switch and power off, which is not only safe and reliable, but also does not affect the residents. and business electricity.
