Embodiment

Please refer to Fig. 1, it has disclosed the instrument base 10 of the utility model one preferred implementation, and this instrument base 10 comprises that an adsorption site 20, is installed on adjusting portion 60 and on the adsorption site 20 and is installed on bearing part 80 on the adjusting portion 60.

Please refer to Fig. 2, Fig. 3, this adsorption site 20 comprises that one paste to inhale part 30, and is installed on to paste and inhales the fixing frame 40 on the part 30 and be installed on a rotary sleeve 50 and a packing ring 52 on the fixing frame 40.

Paste suction part 30 and comprise a soft flat subsides suction sheet 31, and one vertically stretch the column of establishing 32 from paste inhaling the sheet central position, be formed with outstanding outside thread 33 on the outer circumferential face of the upper end of column 32 vertically, outside thread 33 is strip along outer circumferential face and distributes, and is the depression of strip (figure does not show) between the outside thread of strip.

Fixing frame 40 comprise one be used to compress paste inhale sheet 31 compress dish 41 and one sleeve 42 that is sheathed on the column 32.The top of sleeve 42 extends upward step-like attachment post 44, axially is formed with stroke groove 43 along sleeve 42, and the screw thread 33 of column 32 is outside stroke groove 43 is projected into sleeve 42.

Rotary sleeve 50 is sheathed on the sleeve 42, and the inner peripheral surface of rotary sleeve 50 is formed with internal thread 51, and rotary sleeve 50 is rotated in outside thread 33 engagements on internal thread 51 and the column 32, can drive the column 32 that is engaged with and move axially.Be formed with the depression (with reference to figure 1) of the some people's of being convenient to handlings on the outer circumferential face of rotary sleeve 50.

Packing ring 52 is installed on the attachment post 44 of sleeve 42, and by adequate measures, for example blocks key, stops packing ring 52 to rotate around attachment post 44.

When using, the user can place adsorption site 20 on the flat carrier (for example glass) earlier, guarantees to paste suction sheet 31 and flat carrier applying.Rotate rotary sleeve 50 and make column 32 move up, the edge that compresses dish 41 props up subsides and inhales sheet 31, and column 32 pullings are pasted the middle part of inhaling sheet 31 and made progress, thereby form vacuum, and adsorption site 20 promptly is adsorbed on this flat carrier.When desiring removal, rotatable rotary sleeve 50 makes column 32 move downward, and makes and can take off this adsorption site 20 by the vacuum expendable pattern that forms.

With reference to figure 1, Fig. 3, adjusting portion 60 comprises a rotatable swivel mount 61 and a rotatable gear rack device 64 that is installed on the swivel mount 61 that is installed on the fixing frame 40.

This swivel mount 61 comprises a

chassis

62 and 62 two walls 63 upwardly extending, respect to one another from the chassis.Have the hole on the chassis 62, be placed on the attachment post 44, and be connected with sleeve 42 by a screw 53.Swivel mount 61 can rotate around attachment post 44.At the upper surface of packing ring 52 and the lower surface on chassis 62, be formed with at least one elastic protrusion and a plurality of rule along the circumferential direction depression that distribute, that be used to hold this elastic protrusion (figure does not show) respectively, when swivel mount 61 rotates, elastic protrusion constantly goes to another depression from a depression, and after rotation stops, resting in the depression, thereby swivel mount 61 can be around the axial rhythmical rotation of sleeve 42.

This gear rack device 64 comprises a gear-box 68, a gear 69, a tooth bar 70, a knob 73 and a latch 72.The bottom of gear-box 68 is extended with raised line 67 downwards, and raised line 67 stretches between two walls 63, and a screw 65 passes raised line 66 and two walls 63, and cooperates with nut 66, thereby gear rack device 64 is installed on the swivel mount 61.Adjusting screw 65 makes to connect to be become flexible, and gear rack device 64 is rotated around the axle of screw 65, and adjusting screw 65 makes and connects closely, gear rack device 64 can be fixed on a certain pivotal position.

Gear 69 is installed in the gear-box 68, tooth bar 70 and gear 69 engagements.In the present embodiment, tooth bar 70 extends on vertical direction, and tooth bar 70 tops are the horizontally extending flat boards 71 that are connected with bearing part 80 of being used for.The position (with reference to figure 1) of knob 73 outside gear-box 68 is installed on the axle of gear 69, and rotary knob 73 drives tooth bar 70 liftings, i.e. the height of can regulate bearing part 80.Latch 72 is installed on the gear-box 68, is used for locking or discharges tooth bar 70.

Sleeve 42 rotations relatively of the swivel mount 61 of adjusting portion 60, gear rack device 64 swivel mount 61 rotations relatively, and both sense of rotation are perpendicular to one another, therefore, within slewing area, be positioned at bearing part 80 on the adjusting portion 60 and the instrument that is positioned on the bearing part 80 and can be adjusted to multiple attitude.Because the effect of gear rack device 64 also can be adjusted the distance between this instrument and user.

Please refer to Fig. 1, Fig. 4, Fig. 5, bearing part 80 comprises a housing 81, a pair of fixture block 90, a voussoir 95 and plurality of

elastic part

88,89.

Housing 81 roughly is square, and is formed with the slideway 82 that holds fixture block 90, and the slideway that hold voussoir 95 83 vertical with slideway 82 in housing 81.In the present embodiment, slideway the 82, the 83rd forms by corresponding opening acting in conjunction on the slide rail in housing 81 86, limiting stopper 87 and the sidewall.Also be formed with some

U-shaped pieces

84,85 that are used to hold

elastic component

88,89 in the housing 81.

Fixture block 90 is L-shaped, comprises a vertical component 91 and a horizontal component 92.Horizontal component 92 is installed in the slideway 82, and vertical component 91 extends to the top (with reference to figure 1) of housing 81.Horizontal component 92 comprise be positioned at away from an inclined-plane 93 of vertical component 91 ends and and the baffle plate (figure does not show) that extends downwards by the bottom surface, after installing, baffle plate is positioned at the opening of U-shaped piece 85, elastic component 88 1 ends are positioned at U-shaped piece 86, this baffle plate of the other end contact orders about fixture block 90 and clamps toward each other.

Voussoir 95 is used to accept user's operation, thereby order about this fixture block 88 is separated from each other.Being installed in the slideway 83 of voussoir 95 parts, the one end stretches out outside the housing 81, and to accept user's operation, the other end comprises inclined-plane 96 and inserts between two fixture blocks 90 that the inclined-plane 93 of inclined-plane 96 and fixture block 90 cooperates.Voussoir 95 includes the baffle plate (figure does not show) that extends from the bottom surface downwards, after installing, the baffle plate of voussoir 95 is positioned at the opening of U-shaped piece 84, and elastic component 89 1 ends are positioned at U-shaped piece 84, the baffle plate of the other end contact voussoir 95, thus voussoir 95 ordered about away from fixture block 90.

When using, at first, order about fixture block 90 to housing 81 directions promotion voussoir 95 and be separated from each other, vehicle-mounted instrument is placed on the housing 81 of bearing part 80, unclamp voussoir 95 then, elastic component 88 orders about fixture block 90 and contacts and clamp this instrument with instrument.When desiring to unload this instrument, promote voussoir 95 to housing 81 directions and order about fixture block 90 separately, unload this instrument then.
