A kind of push-pull mechanism for busway inserting case
Technical field
The present invention relates to a kind of push-pull mechanisms for busway inserting case.
Background technique
Modern high-rise building and large-scale workshop need huge electric energy, and in face of hundreds and thousands of peaces needed for this huge load
The powerful electric current of training will select safe and reliable transmission equipment, and bus-bar system is to select well.Bus duct system is one
The power distribution equipment of a efficient conveying electric current, has especially adapted to higher and higher building and large-scale plant economical rationality wiring
It needs.Bus duct is new circuit mode developed by the U.S., referred to as " Bus-Way-System ", it is with copper or aluminium
As conductor, with non-alkene insulating supporting, be then attached in metallic channel and the novel conductor that is formed.
Nowadays at indispensable wiring mode in the electrical equipments such as skyscraper, factory, electric system.Due to big
The needs of the various building electric power such as building, factory, need to take out by the electric energy in bus duct using jack box, and due to factory
Interim power-off cost is too big, generally requires in case of constant power, jack box is connected with bus duct, this just brings centainly
Security risk.
Summary of the invention
The purpose of the present invention is to solve the above the deficiencies in the prior art, propose a kind of for busway inserting case
Push-pull mechanism.
A kind of push-pull mechanism for busway inserting case, including fixing seat, fixing clip and lead screw;The fixing seat
Positioned at the top of bus duct, the fixing clip is L-shaped, and the bottom of fixing clip is connected in the protrusion of bus groove sidewall,
The top of fixing clip is connected by clamping screw with the bottom of fixing seat, and the end of the lead screw passes through fixing seat and rocking bar phase
Even, the rocking bar and fixing seat rotation connect, and feed screw nut is arranged on lead screw, and the feed screw nut passes through connecting rod and work
Movable plate is connected, and rubber pad is connected on the movable plate, the head of the rubber pad is connected on the outer wall of jack box, described
Buckle is connected on connecting rod, the head of the buckle is equipped with U-shaped bayonet, the limited post of the U-shaped bayonet and jack box end
Mutually it is clamped.
Preferably, the outer wall of the rubber pad is tapered.
Preferably, the tail portion of the buckle is connected by bolt with connecting rod.
Preferably, the material of the rubber pad is polyurethane.
Preferably, the quantity of the fixing clip is four.
The utility model has the advantages that
Entire mechanism is made of fixing seat, lead screw, movable plate, fixing clip, rocking bar.By fixing seat and fixing clamp when use
Block cooperation is fixed on bus duct upper cover plate.By shaking rocking bar clockwise, lead screw rotation drives movable plate to travel forward, pushes
Jack box advances along bus slot cover board.By shaking rocking bar counterclockwise, lead screw rotation drives movable plate to move backward, drags grafting
Case is retreated along bus slot cover board.
It is to push jack box to move forward by rubber pad when jack box being pushed to carry out grafting with bus duct forward, In
When grafting, rubber pad can play good buffer function, prevent excessive grafting damage equipment;And pulling jack box separate female
It is to be driven by buckle, movement speed is fast, easy to operate when wire casing.

Specific embodiment
In order to deepen the understanding of the present invention, below in conjunction with embodiment and attached drawing, the invention will be further described, should
The examples are only for explaining the invention, is not intended to limit the scope of the present invention..
As Figure 2-3, a kind of push-pull mechanism for busway inserting case, including fixing seat 4, fixing clip 6 and silk
Thick stick 3;The fixing seat 4 is located at the top of bus duct 2, the fixing clip 6 altogether there are four.
Fixing clip 6 is L-shaped, and the bottom of fixing clip 6 is connected in the protrusion of 2 side wall of bus duct, the top of fixing clip 6
Portion is connected by clamping screw (not shown) with the bottom of fixing seat 4, and the end of the lead screw 3 passes through fixing seat 4 and shakes
Bar 5 is connected, the rocking bar 5 and the rotatable connection of fixing seat 4, is arranged with feed screw nut, the feed screw nut on lead screw 3
It is connected by connecting rod with movable plate, rubber pad 7 is connected on the movable plate, the outer wall of the rubber pad 7 is tapered, rubber pad
7 material is polyurethane.
The head of rubber pad 7 is connected on the outer wall of jack box 1, and buckle is connected on the connecting rod, the buckle 8
Head is equipped with U-shaped bayonet, and the U-shaped bayonet and the limited post of 1 end of jack box are mutually clamped, and the tail portion of the buckle 8 is logical
Bolt is crossed to be connected with connecting rod.
As shown in Figure 1, problem to be solved is how jack box 1 moving forward the L shape being inserted on bus duct 2
In bulge-structure, or when being not necessarily to electricity consumption, jack box 1 is moved backward, is sailed out of from the L shape bulge-structure on bus duct 2.
Fixing seat 4 and the cooperation of fixing clip 6 are fixed on bus duct upper cover plate when use.Wherein, clamping screw is (in figure
Do not show) it is screwed in threaded hole 9 by screw thread.
By shaking rocking bar 5 clockwise, the rotation of lead screw 3 drives movable plate to travel forward, pushes jack box 1 along bus slot cover
Plate advances.By shaking rocking bar 5 counterclockwise, the rotation of lead screw 3 drives movable plate to move backward, drags jack box 1 along bus slot cover
Plate retreats.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
