Abstract
An automatic lubrication device for an outdoor switch is arranged beside one contact of an outdoor switch. The automatic lubrication device for the outdoor switch comprises a shell; a spring, a pressure plate and lubrication grease are arranged in the shell. The contact has an oil infiltration port. When the switch is closed, the other contact closes the oil infiltration port on the contact, the lubrication grease can not infiltrate. When the switch is opened, the two contacts are separated, the oil infiltration port is opened simultaneously, and the lubrication grease infiltrates from the oil infiltration port under the effect of an elastic force pressure, thus the effect of reducing the friction is obtained.
Description
Technical field
The utility model belongs to the high-voltage appliance switch field, specifically a kind of outdoor switch automatic lubrication installation.
Background technology
Outdoor switch has increased branch, has run the frictional force when closing jointly because environment badly causes the oxidation of contact easily, in maintenance or maintain the time-division, run relatively difficulty of pass jointly.
Summary of the invention
The purpose of this utility model is at dividing, run jointly the defective of closing the frictional force increase after the existing outdoor switch contact surface oxidation, propose a kind of simple in structure, switch branch, fashionable out of doors, penetrating oil automatically, the outdoor switch automatic lubrication installation that reduces friction.
The purpose of this utility model is achieved in that outdoor switch automatic lubrication installation of the present utility model is arranged on the side of a contact of outdoor switch, the outdoor switch automatic lubrication installation comprises shell, spring, pressing plate and lubricant grease are arranged in the shell, on the above-mentioned contact oil seepage port is arranged.
Outdoor switch automatic lubrication installation of the present utility model is owing to be arranged on the side of a contact, and another contact is airtight with the oil seepage port on the above-mentioned contact during switch closure, and lubricant grease can not ooze out.When switch open, two contacts separate, and oil seepage port is opened simultaneously, and lubricant grease oozes out from oil seepage port elastic force pressure, reaches the effect that reduces friction.
Description of drawings
Fig. 1 is the structural representation of outdoor switch automatic lubrication installation of the present utility model.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing:
As shown in Figure 1, a kind of outdoor switch automatic lubrication installation of the present utility model is arranged on the side of the moving contact 1 of outdoor switch, and the outdoor switch automatic lubrication installation comprises shell 3, and spring 4, pressing plate 5 and lubricant grease 6 are arranged in the shell 3, and oil seepage port 7 is arranged on the moving contact 1.
Fixed contact 2 is airtight with the oil seepage port on the moving contact 17 during switch closure, and lubricant grease 6 can not ooze out.When switch open, fixed contact 2 separates with moving contact 1, and oil seepage port 7 is opened simultaneously, and lubricant grease 6 oozes out from oil seepage port 7 under the effect of elastic force pressure, reaches the effect that reduces friction.
