Abstract

The utility model discloses a push-and-pull institution for bus duct jack box, including fixing base, lead screw, fly leaf, fixed clamp splice, rocker. When in use, the fixed seat and the fixed clamping block are matched and fixed on the bus duct upper cover plate. By rocking the rocker clockwise, the lead screw rotates to drive the movable plate to move forward, and the jack box is pushed to move forward along the bus duct cover plate. By shaking the rocker counterclockwise, the screw rotates to drive the movable plate to move backwards, and the jack box is dragged to retreat along the bus duct cover plate. When the jack box is pushed forwards to be plugged with the bus duct, the jack box is pushed to move forwards through the rubber pad, and the rubber pad can play a good buffering role during plugging so as to prevent equipment from being damaged by excessive plugging; and when the jack box is pulled to be away from the bus duct, the jack box is driven by the buckle, so that the moving speed is high, and the operation is convenient.

Description

Push-pull mechanism for bus duct jack box

Technical Field

The utility model relates to a push-and-pull institution for bus duct jack box.

Background

Modern high-rise buildings and large workshops need huge electric energy, and safe and reliable conduction equipment needs to be selected in the face of the huge load needing hundreds of thousands of amperes of strong current, so that a bus system is a good choice. The bus duct system is a power distribution device for efficiently transmitting current, and particularly meets the requirements of economic and reasonable wiring of higher and higher buildings and large-scale factories. The Bus duct is a new circuit type developed by the united states and called "Bus-Way-System" and is a new conductor formed by using copper or aluminum as a conductor, using a non-olefinic insulating support, and then being installed in a metal groove.

Nowadays, the wiring system is indispensable for electrical equipment and power systems in high-rise buildings, factories, and the like. Because the needs of various building electric powers such as building, mill, etc. need use the jack box to take out the electric energy in the bus duct, and because the interim outage cost of mill is too big, often need be under the circumstances of not cutting off the power supply, link to each other jack box and bus duct, this has just brought certain potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims at solving the defects of the prior art, and providing a push-pull mechanism for a bus duct jack box.

A push-pull mechanism for a bus duct jack box comprises a fixed seat, a fixed clamping block and a lead screw; the fixing base be located the top of bus duct, the fixed clamp splice be L shape, the bottom joint of fixed clamp splice is on the arch of bus duct lateral wall, the top of fixed clamp splice links to each other through the bottom of locking bolt with the fixing base, the end of lead screw passes the fixing base and links to each other with the rocker, rocker and fixing base swivelling joint, the cover is equipped with screw nut on the lead screw, screw nut pass through the connecting rod and link to each other with the fly leaf, the fly leaf on even have the rubber pad, the head butt of rubber pad is on the outer wall of jack box, the connecting rod on all even have the buckle, the head of buckle is equipped with the U-shaped bayonet socket, the spacing post looks joint of U-shaped bayonet socket and jack box tip.

Preferably, the outer wall of the rubber pad is conical.

Preferably, the tail part of the buckle is connected with the connecting rod through a bolt.

Preferably, the rubber pad is made of polyurethane.

Preferably, the number of the fixing clamping blocks is four.

Has the advantages that:

the whole mechanism consists of a fixed seat, a screw rod, a movable plate, a fixed clamping block and a rocker. When in use, the fixed seat and the fixed clamping block are matched and fixed on the bus duct upper cover plate. By rocking the rocker clockwise, the lead screw rotates to drive the movable plate to move forward, and the jack box is pushed to move forward along the bus duct cover plate. By shaking the rocker counterclockwise, the screw rotates to drive the movable plate to move backwards, and the jack box is dragged to retreat along the bus duct cover plate.

When the jack box is pushed forwards to be plugged with the bus duct, the jack box is pushed to move forwards through the rubber pad, and the rubber pad can play a good buffering role during plugging so as to prevent equipment from being damaged by excessive plugging; and when the jack box is pulled to be away from the bus duct, the jack box is driven by the buckle, so that the moving speed is high, and the operation is convenient.

Detailed Description

In order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.

As shown in fig. 2-3, a push-pull mechanism for a bus duct jack box comprises a fixed seat 4, a fixed clamping block 6 and a screw rod 3; the fixing seat 4 is positioned above the bus duct 2, and the number of the fixing clamping blocks 6 is four.

Fixed clamp splice 6 is L shape, and the bottom joint of fixed clamp splice 6 is on the arch of bus duct 2 lateral wall, and locking bolt (not shown in the figure) is passed through at the top of fixed clamp splice 6 and is linked to each other with the bottom of fixing base 4, the end of lead screw 3 passes fixing base 4 and links to each other with rocker 5, rocker 5 and the rotatable connection of fixing base 4, the cover is equipped with screw nut on the lead screw 3, screw nut pass through the connecting rod and link to each other with the fly leaf, the fly leaf on even have rubber pad 7, the outer wall of rubber pad 7 is the toper, and the material of rubber pad 7 is polyurethane.

The head of rubber pad 7 butt on the outer wall of jack box 1, the connecting rod on all link and have the buckle, the head of buckle 8 is equipped with the U-shaped bayonet socket, the spacing post looks joint of U-shaped bayonet socket and jack box 1 tip, the afterbody of buckle 8 pass through the bolt and link to each other with the connecting rod.

As shown in fig. 1, the problem to be solved is how to move the jack box 1 forward to insert into the L-shaped protrusion structure on the bus duct 2, or move the jack box 1 backward to drive away from the L-shaped protrusion structure on the bus duct 2 when no electricity is needed.

When in use, the fixed seat 4 and the fixed clamping block 6 are matched and fixed on the bus duct upper cover plate. Wherein a locking bolt (not shown) is screwed into the threaded hole 9.

By shaking the rocker 5 clockwise, the screw 3 rotates to drive the movable plate to move forward, and the jack box 1 is pushed to move forward along the bus duct cover plate.
