Embodiment
Below in conjunction with 1 to 5 pair of the utility model of accompanying drawing, make and illustrating:
A kind of screw assembly of fast assembling-disassembling cover plate, this screw assembly is fixed on cover plate 6 on pedestal, described screw assembly comprises fixing column 1 and positioning block 2, described positioning block 2 is fixed on pedestal outside, described cover plate 6 is fixed on positioning block 2 outsides, described pedestal, positioning block 2 and cover plate 6 are provided with the through hole of perforation, and fixing column 1 is through described through hole.
Concrete, described fixing column 1 comprises the compressed part 10 of inner screw part 11 and outer end, described screw part 11 is through described through hole, described compressed part 10 is provided with the lug 12 outwards circumferentially protruding, described lug 12 is for compressing cover plate 6, described cover plate 6 is provided with side opening 62 in through hole outer circumferential sides, and described side opening 62 can pass through lug 12.Between described compressed part 10 and positioning block 2, be provided with and stop both counterrotating concavo-convex locking structures 7, in described screw part 11, be socketed with spring 3, the locking nut 4 that has been threaded on screw part the inner, described spring 3 is arranged between positioning block and the locking nut 4 of screw part the inner.Spring outer end is pressed in positioning block plane like this, spring the inner is pressed in locking nut plane, spring is just given middle inside axial force of fixing column, make lug 12 elastic compressions on fixing column 1 on cover plate 6, and locking and the release of concavo-convex locking structure 7 are also convenient in the setting of spring 3.
Fixing column 1 is an interior hexagonal injection moulding screw, and its one end is for establishing threaded screw part, and the other end is compressed part, and compressed part exterior edge face is provided with inner hexagonal hole, conveniently by hexagon wrench, rotates fixing column.Described compressed part 10 comprises the flange of being located at fixing column 1 outer end, and described lug 12 is located at the outer circumferential sides of flange, and two lugs are symmetricly set on the T-shaped structure in fixing column both sides.
The disc-shaped structure that positioning block 2 is made for nylon, described positioning block 2 exterior edge faces are provided with bulge loop 21 around through hole.Described concavo-convex locking structure is just arranged between flange interior edge face and positioning block exterior edge face.Bulge loop inserts in the through hole of cover plate, and also insert in the through hole of cover plate flange the inner simultaneously, and concavo-convex like this locking structure 7 is all positioned at the through hole of cover plate when locking.On positioning block 2, being also provided with 22, two screws of two screws interval 180 degree on same circumference arranges.Fixing by screw 5 between described positioning block and pedestal, screw thread is fixed in this screw 22, and screw end is provided with inner hexagonal hole, is convenient to rotate by hexagon wrench.
Wherein, above-mentioned concavo-convex locking structure 7 is arc groove and the circular arc projection that bulge loop hoop and flange are arranged circumferentially.On concrete bulge loop and flange, be respectively provided with four circular arc projections of four arc grooves, arc groove and circular arc projection are in circumferential equal intervals setting, the structural correspondence of the structure of arc groove and circular arc projection, arc groove on bulge loop and flange and circular arc projection are at once like this, both could be just in time chimeric, and the advantage of arc groove and circular arc projection is, rotation fixing column, arc groove and circular arc projection can stagger very easily.
Described cover plate is provided with to the groove 61 of substrate-side depression in through hole cylindrical side.Lug is pressed together on the bottom surface of groove 61 shroud press is fixed.This design had both been convenient to fixing column shroud press had been fixed, and had again certain aesthetic.
During use, by this screw assembly, cover plate 6 is fixed on pedestal, this pedestal also can be with replacing on frame or other parts.This pedestal provides installation position, by two screws 5, positioning block 2 is fixed on pedestal, and screw stretches into and is fixed on pedestal through the screw 22 on positioning block 2.Through hole on pedestal is used for holding fixing column 1, spring 3.
During installation, locking nut 4 is screwed to certain position, start pressing spring 3, spring 3 just moves to positioning block 2 directions, because positioning block 2 maintains static, the inner side end of positioning block 2 hinders spring 3 motions, at this time spring 3 just produces compression, due to the spring 3 length generation elastic force that changes, directive effect of elastic force is in positioning block 2 inner side ends, make positioning block 2 produce outside movement tendency, another rightabout elastic force acts on locking nut 4 end faces (at this time locking nut is screwed on fixing column), makes locking nut 4 produce outside movement tendency.Due to positioning block 2 transfixions, so spring 3 elastic force make the connecting body of locking nut 4 and fixing column 1 outwards move (positioning block produces outside movement tendency, opposite direction).Until positioning block contacts with the another side of cover plate or positioning block, fixing column is not moving axially, at this time positioning block, spring, locking nut, and fixing column position is relatively static, and camber of spring is little, and the elastic force of generation is very little.In order to make this screw assembly produce suitable pressure, locking nut continues to be screwed into a segment distance, at this time, positioning block and fixing column relative position are motionless, locking nut is with respect to fixing column change in location, be screwed into a segment distance, spring produces certain elastic force (at this moment can be considered as locking nut and fixing column is structure as a whole.Locking nut has locking effect, so just relative with fixing column fixing, the work elastic force of spring has also produced.During work, in the effect of spring force, the lug on fixing column, under the effect of spring force, is pressed on cover plate always.If fixing column is to moving away from positioning block direction, at this time, locking nut is Compress Spring further, produces larger elastic force, orders about lug and moves to cover plate direction.
Under cover plate 6 and pedestal stationary state, lug 12 is pressed on cover plate 6 and can realizes cover plate is fixed on to the object on pedestal.Now, on fixing column 1 and positioning block 2, concavo-convex locking structure 7 is in the lock state, the circular arc projection on fixing column 1 and arc groove respectively with positioning block 2 on arc groove and circular arc projection mutually chimeric.In the time of need to dismantling cover plate 6, turn fixing column, while making lug over against side opening 62 on cover plate, circular arc projection on fixing column and arc groove respectively with positioning block 2 on arc groove and circular arc projection dislocation, now lug is away from positioning block 2, cover plate, in unrestricted state, can be dismantled the action that also can adjust like this.The process of installation and removal cover plate only needs directly with hand or hexagon wrench rotation fixing column 90, to spend, simple and convenient.
