Embodiment
Now the invention will be further described by reference to the accompanying drawings, Fig. 1 is a kind of embodiment of the present invention, comprise box frame, chamber door, top cover and shaft coupling, box frame is generally the framework of rectangular shape, each of cuboid arranges opening, be provided with outwardly flange in the upper edge of opening and lower edge, chamber door to be buckled in outside flange with box frame as being flexibly connected.Arrange sealing strip between box frame and door, top cover is arranged on box frame top, and shaft coupling is arranged on top cover top, and the center that usual output shaft is positioned at top cover is stretched out, and shaft coupling is connected with the output shaft stretching out top cover.The present invention also comprises axle portion protector and door portion protector.
Axle portion protector comprises sealing ring and axle sleeve, sealing ring is v-ring, namely sealing ring is cirque structure, its cross section is V-shaped, this V-arrangement cross section is specially: sealing ring is provided with an annular groove along upper surface, and the cross section of this groove is V-shaped, and the annulus area of the lower surface of sealing ring is less than the area of upper surface, and placed in the middle, and the both sides of sealing ring are all in skewed.Described axle sleeve is cylindrical, and its hole size is corresponding to output shaft excircle dimension, and axle sleeve is fixedly connected on top cover top and is placed on output shaft then outward, the through hole that namely axle sleeve is arranged on top cover, output shaft stretches out.The lower end of described shaft coupling is placed on the outside of axle sleeve, shaft coupling lower end inner wall is provided with groove, the endoporus of this groove and shaft coupling forms stepped hole, the degree of depth of usual groove is corresponding to the height of axle sleeve, described sealing ring is arranged between axle sleeve and shaft coupling, in the groove of shaft coupling, see Fig. 2.In the present embodiment, the groove inner wall of sleeve outer circle and shaft coupling is provided with the stopper slot installing sealing ring, and sealing ring is installed in stopper slot can prevent its displacement, guarantees sealing effectiveness.
Described door protector comprises the second sealing frame and elastic packing plate, the cross section that second sealing frame is made up of vertical edge and horizontal edge is into seemingly rectangular-shaped strip structure, angle between horizontal edge and vertical edge is less than 90 degree, its vertical edge is fixedly connected with inside the flange on box frame, its horizontal edge stretches out parallel with flange and stretches out flange, from cross section, stretch out the outside of flange outside horizontal edge, usual horizontal edge stretches out outer 2 millimeters of flange.Described elastic packing plate is strip rectangular slab, and its length is corresponding to gate-width degree, and is horizontally installed on an inner side, corresponding with the horizontal edge of the second sealing frame, and namely after door and box frame snapping, elastic packing plate contacts with horizontal edge is corresponding, sees Fig. 3 and Fig. 4.Elastic packing plate thickness is greater than the thickness of sealing strip, usual elastic packing plate thickness is greater than sealing strip thickness 2 millimeter, and elastic packing plate is generally made up of foamed silastic or ethylene propylene diene rubber, therefore, elastic packing plate has good elasticity, also has certain wettability power.Sealing strip between described box frame and door is hollow sealing strip, and it is fixedly connected on the outside of flange, and sealing bar and flange form the first sealing frame.In the present invention, the flange on box frame can also be four edge settings along opening.
When mechanism's casing of isolating switch uses out of doors, those parts that sand and dust mainly may stretch out casing from output shaft enter, namely enter between top cover and output shaft, due to the present invention on top cover, the output shaft through hole of stretching out is provided with axle sleeve, be provided with again the convenient groove installing sealing ring in the lower end being placed on the shaft coupling outside axle sleeve, sealing ring is arranged on after between axle sleeve and shaft coupling and can effectively prevents moisture content and sand and dust from entering in casing from top cover; Sealing ring adopts v-shaped structure, its top elasticity is larger, after installing, its top is suitably compressed, even if the weather colded and heat succeed each other, prevent from occurring gap herein because expanding with heat and contract with cold, guarantee sealing property, simultaneously also prevent from pursuing simply frictional force when sealing property occurs that excessive interference fit causes shaft coupling to rotate excessive and affect its rotation.In addition have the stop of axle sleeve, sand and dust more can not enter box house along the through hole of output shaft and top cover, effectively anti-dust, simultaneously also can waterproof.
The present invention is also provided with portion's protector, namely on the flange of box frame, be provided with the second sealing frame of approximate right angle shape, its horizontal edge is protruding in flange, inside door, corresponding to the position of horizontal edge, be provided with elastic packing plate, simultaneously at flange arranged outside hollow seal bar.After knocker is connected on box frame, hollow seal bar on flange is extruded by door, the good springiness of hollow seal bar, contact with door forming surface after extruding, improve sealing property, first sealing protection is formed after sealing strip on flange contacts with door, meanwhile, the outer side edges of above-mentioned horizontal edge and the elastic packing plate on door are also extrude to contact, horizontal edge and elastic packing plate are linear contact lay, horizontal edge stretches out outside flange, therefore the contact of horizontal edge and elastic packing plate is tightr, it forms second sealing protection, first protection has effectively intercepted most of moisture content and has entered in casing, the moisture content entered on a small quantity or sand and dust stop by the second sealing protection of more close contact, sand and dust and moisture content is avoided to enter in casing the normal operation of the equipment that affects.Second sealing frame is fixedly connected on inside flange by its vertical edge, as being welded to connect or riveted joint etc., easily manufacturing, can having transformed on existing product basis, without the need to the box frame more renewed, reducing costs; In addition, because the vertical edge of the second sealing frame and the angle of horizontal edge are less than 90 degree, particularly with the second sealing frame being positioned at top flange and carrying out being connected, see Fig. 4, its horizontal edge is inclined plane low after front height, this structure can make the moisture content that enters from first sealing protection or sand and dust fall in the rear side of horizontal edge and the angle of vertical edge, and can not along entering casing between horizontal edge and elastic packing plate, in order to prevent moisture content or sand and dust from falling in casing from the two ends of the second sealing frame, baffle plate can also be set at the two ends of the second sealing frame.
The present invention is rational in infrastructure, easily manufactures, and having can effective waterproof, feature that again can be anti-dust.
