Abstract
The utility model discloses a sealing device for an instrument adjusting apparatus. The utility model is characterized in that a convex rectangle rib is arranged at the periphery of an adjusting component of an instrument casing, and the inner side surface of a cover board is provided with a rectangle groove in which a rubber seal ring is arranged. The cover board is a cover turning type and is connected with the instrument casing through pins, so the cover board can be agilely opened and closed. When the cover board is opened, the adjusting component is exposed, which is convenient for adjustment and operation. When the cover board is closed, the convex rectangle rib on the instrument casing is pushed into the groove on the cover board to squeeze the seal ring in the groove to be deformed, which ensures that an adjusting device of the instrument is sealed effectively. Thereby, and the performance of the instrument is not influenced by the bad environment of a work place.
Description
Technical field
The utility model belongs to the automation instrument technology field, and the sealing configuration that relates in particular to the instrument regulating device improves.
Background technique
At present instrument is adjusted assembly surface, adopts the horizontal moving type cover plate mostly, hides rain with two screw cover plates retaining ashes at ordinary times, when instrument is adjusted, backs out one of them screw, removes cover plate and exposes the adjustment assembly and return to zero, transfer the range operation.This structure does not have seal action, the salt fog in instrumentation place, steam, acid and alkali corrosion medium are easily along the slit between cover plate and the instrument housing, enter gauge internal, corrode regulating device even corrosion gauge internal electronics chamber, cause the instrument cisco unity malfunction.
Summary of the invention
The purpose of this utility model provides a kind of easy and simple to handle, reliable sealing instrument regulating device, so that prevent that effectively various corrosive gass to adjusting the erosion of assembly, prolonging the working life of instrument.
For finishing the technological scheme that above-mentioned purpose adopts be: a kind of by instrument housing, the instrument regulating device that cover plate is formed, it is characterized in that instrument housing adjustment assembly periphery has the rectangle muscle of a projection, the cover plate inner side surface has a rectangular recess, the built-in rubber rectangular ring of groove, adjusting the rectangle muscle of assembly periphery and the size of cover plate inner side surface groove matches, during cover plate closing, the rectangle muscle of projection heads into groove, the crush seal circle makes its distortion, thereby realize effectively sealing, two screws are connected cover plate by the fixed installation hole on the cover plate respectively with the instrument housing lock ring.
Described cover plate is a hinge-lid type, and the outside, two ends of the two ends of cover plate and instrument regulating device has mounting hole respectively, passes described mounting hole with pin and is connected cover plate and transmitter housing with cover board hole.Rubber seal boundary dimension matches with groove on the cover plate, and is rectangular.
The beneficial effects of the utility model are that hinge-lid type cover plate unlatching closed procedure is flexible, expose the adjustment assembly when cover plate is dug, adjust easy to operately, the rectangle muscle of the projection during cover plate closing on the instrument housing heads into the cover plate groove, extruding makes the seal ring distortion, thereby has guaranteed effective sealing.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1, instrument regulating device decomposing schematic representation;
Fig. 2, cover plate inner side surface structural representation;
Fig. 3, the A-A sectional view of Fig. 2;
Fig. 4, rubber rectangular ring shape schematic representation.
Among the figure, 1 housing, 2,2 ' inserts pin, 3,3 ' hole, 4 adjust assembly, 5 rectangle muscle, 6 seal rings, 7,7 ' hole, 8 cover plates, 9,9 ' hole, 10 grooves.
Embodiment
By shown in Figure 1, a kind of instrument regulating device of forming by instrument housing, cover plate, it is characterized in that instrument housing 1 adjustment assembly 4 peripheries have the rectangle muscle 5 of a projection, from Fig. 2 and Fig. 3 as seen, cover plate 8 inner side surfaces have a rectangular recess 10, groove 10 built-in rubber rectangular rings 6, the size of rectangle muscle 5 and groove 10 matches, during cover plate 8 closures, the rectangle muscle 5 of projection heads into groove 10, crush seal circle 6 makes its distortion, and porose 9 and 9 ', two screws are connected cover plate 8 with 9 ' by fixed installation hole 9 respectively on the cover plate 8 with transmitter housing 1 lock ring.
Described cover plate 8 can be a hinge-lid type, and cover plate 8 two ends are respectively porose 7 and 7 ', and instrument is adjusted the outside, assembly 4 two ends has mounting hole 3 and 3 ', pin 2 to pass hole 3 and hole 7, and pin 2 ' passes hole 3 ' and is connected cover plate 8 and instrument housing 1 with hole 7 '.Seal ring 6 shown in Figure 4 is a rectangle, and boundary dimension matches with groove 10 on the cover plate 8, and certainly, seal ring 6, groove 10 also can be circular or other shape.
