Abstract

The utility model belongs to low-voltage equipment for power transmission and distribution, relating to an advancing mechanism of a bus plugging box used for plugging and connecting the bus plugging box and a busway, which comprises a housing combined by mutually buckled bottom plates and a front end plate; wherein, the front end plate is provided with a rotary shaft, one end of the rotary shaft is positioned outside the front end plate and used as a rotary head for an operator to carry out rotation operation, while the other end of the rotary shaft is positioned in a empty cavity inside the front end plate and connected with a driving disc; the outer edge of the driving disc is hinged with one end of a connecting rod, and the other end of the connecting rod is hinged on a sliding plate; the sliding plate is provided with a sliding groove on the vertical direction, the sliding groove is fixed on and matched with a pintle on the housing so as to limit the sliding plate to move in the vertical direction, the lower end of the sliding plate extends from an opening on the lower end of the housing and is connected with a link press span, and the link press span is provided with a solid component used for fixedly connecting the bus groove. The equipment has simple structure and convenient and labor-saving operation, which can improve plugging reliability and prevent misoperation.

Description

Bus jack box propulsive mechanism

Technical field

The utility model belongs to the low pressure equipment for power transmission and distribution, relates to a kind of bus jack box propulsive mechanism that bus jack box and bus duct are carried out socket connection of being used for.

Background technology

In the low pressure electric line, the tap of carrying out the branch road circuit need adopt the bus jack box to peg graft on bus duct when drawing.The grafting of existing bus jack box and bus duct generally is to be undertaken by the mode that manually directly pushes, because the frictional resistance between contact and other plug components, not only make the grafting process extremely require great effort, and can't guarantee that jack box and bus are pegged graft reliably puts in place, in addition, also can't show the residing service position of bus jack box intuitively, thereby increase the probability of misoperation.

Summary of the invention

Technical problem to be solved in the utility model is, provide a kind of simple in structure, rapid operation convenient, can improve the grafting reliability, prevent the bus jack box propulsive mechanism of misoperation.

Bus jack box propulsive mechanism of the present utility model includes a housing of being made up of the base plate and the front shroud of mutual fastening, a rotating shaft is installed on front shroud, rotating shaft one end is positioned at the front shroud outside as the swivel head for operator's rotary manipulation, the other end of rotating shaft is arranged in the cavity of front shroud inboard and connects a driving-disc, one end of the outer rim of driving-disc and a connecting rod is hinged, the other end of connecting rod is hinged on the slide plate, have the chute of vertical direction on this slide plate, described chute cooperates with pin on being fixed on housing and the limited in the vertical direction of slide plate is moved, the lower end of slide plate is stretched out and is connected with a link from the opening of housing lower end, and link is provided with firm that is used for fixedlying connected with bus duct.

Described shell rim is provided with and is used for it is installed in installing hole on the bus jack box.

The swivel head in the described front shroud outside is a hexagonal section.

Also be provided with the pointer that is connected with rotating shaft in the front shroud outside.

The utility model is simple in structure, the operator rotates swivel head by spanner or specific purpose tool and can finish the insertion of jack box or withdraw from when using, and it is easy to operate, laborsaving, reliability is high; In addition, can also show the service position intuitively by the pointer of outside, to avoid taking place misoperation.

Fig. 2 is the planar structure schematic diagram of inboard each parts of front shroud of the present utility model;

Fig. 3 is the planar structure schematic diagram in the front shroud of the present utility model outside.

Embodiment

As shown in the figure, the housing of this bus jack box propulsive mechanism is fastened by base plate 1 and front shroud 2 and forms, be provided with the driving-disc 4 that is installed in the rotating shaft 3 in its inner chamber, driving-disc outer rim and connecting rod 5 one ends are hinged, connecting rod 5 other ends and slide plate 6 are hinged, and slide plate is spacing by vertical chute 7 and the pin 8 that is fixed on the housing, and it can vertically be moved under the drive of driving-disc and connecting rod, housing is stretched out in the lower end of slide plate 6, and fixedlys connected with a link 9.

When this mechanism uses, housing is fixedly mounted on the bus jack box by the installing hole 10 at its edge, the link of lower end is connected with bus duct external stability by firm 11, at this moment use spanner or specific purpose tool to rotate the hexagon swivel head 12 in the front shroud outside, make slide plate flexible, jack box can be furthered or push away bus duct, finish the process of plugging and unplugging.The service position of jack box can be indicated by the pointer 13 that the front shroud outside is connected with rotating shaft.
