The specific embodiment

Please refer to Fig. 1, it has disclosed the utility model one preferred enforcement puts the instrument base 10 of formula, and this instrument base comprises that a permanent seat 20 and is installed on the supporting part 70 of permanent seat 20 upper ends.

Please refer to Fig. 2, Fig. 3, it has disclosed the structure of the supporting part 70 of this instrument base 10.This supporting part 70 comprises a housing 71, a pair of fixture block 80, a gear 91, at least one first elastic component 92 and a lockout mechanism 95.

Housing 71 roughly is square, comprises upper shell 72 and lower house 75, is formed with the chute 73 that holds fixture block 80 between the two side of upper shell 72.

Fixture block 80 is the L type, and it comprises a vertical component 81 and a horizontal component 82, and horizontal component 82 is being installed in the chute 73 toward each other from the both sides of upper shell 72 respectively, and vertical component 81 extends to (with reference to figure 1) on the upper shell 72.Extend a tooth bar 83 from horizontal component 82 away from an end of vertical component 81, along being distributed with some positioning grooves 84 on the lateral surface of the bearing of trend of tooth bar 83.

Gear 91 by and upper shell 72 in the cooperation of registration masts (figure does not show) be installed in the housing 71 and respectively with tooth bar 83 engagements of two fixture blocks 80.

In the present embodiment, first elastic component 92 is a torsion spring, and it is placed on the gear 91, and two ends are limited by the projection on gear 91 and the upper shell 72 (figure does not show) respectively, thereby give gear 91 1 torsion, orders about gear 91 and rotates, and makes fixture block 80 each other from motion.

Lockout mechanism 95 is used for pinning or discharging fixture block 80.When lockout mechanism 95 pinned fixture block 80, fixture block 80 can not move; When lockout mechanism 95 discharged fixture block 80, fixture block 80 can move.

In the present embodiment, lockout mechanism 95 comprises a thimble 96, one second elastic component 97 and a button 98.The thimble 96 and second elastic component 97 are installed in the housing 71, and second elastic component 97 orders about thimble 96 and enters positioning groove 84 on the tooth bar 83, thereby pin fixture block 80.Button 98 is the spring-piece type button, and it is articulated in the housing 71, and an end is positioned at 74 places, hole on the housing 71, and the other end is connected with thimble 96.The 74 places formula button 98 that pushes shrapnel can order about thimble 96 and withdraw from positioning groove 84 in the hole, thereby discharges fixture block 80.

When using, instrument (as navigating instrument) places on the housing 71 and is clamped between the L type fixture block 80, and the thimble 96 of lockout mechanism 95 is arranged in the positioning groove 84 of fixture block 80, thereby pins fixture block 80, prevents that fixture block 80 from unclamping.When desire when instrument base 10 unloads this instrument, the formula that can push shrapnel button 98 makes thimble 96 withdraw from positioning groove 84, make L type fixture block 80 be released, this moment, torsion spring 92 ordered about gear 91 rotations, make fixture block 80 each other from motion, the clamping of 80 pairs of these instruments of fixture block is unclamped, thereby this instrument can be removed.

It is disclosed that the structure of supporting part 70 is not limited to above-mentioned embodiment.For example: when the thimble 96 of this lockout mechanism is positioned at the corner of housing 72, can one can replace spring-piece type button 98 along the common key-press that thimble 96 sense of motions slide.Perhaps, this lockout mechanism 95 can be to be slidably mounted on the housing 71 and and the embedded block of gear 91 cooperations.When embedded block embeds the between cog of gear 91, gear 91 locked can not rotations; When embedded block slid off the between cog of gear 91, gear 91 was released and can rotates.

First elastic component 92 also is not limited to torsion spring, for example its can be two respectively with fixture block 80 bonded assembly springs, described spring orders about fixture block 80 respectively each other from motion.

This supporting part 70 can be connected with the permanent seat of various different structures, and is fixed on the automobile by permanent seat.In Figure 46, disclosed a kind of permanent seat 20 wherein, this permanent seat 20 is an adsorption site, and this adsorption site 20 comprises that one paste to inhale part 30, a spring 56, and is installed on and pastes the fixed mount 40 inhaled on the part 30, dead man 55, be installed on an edge type strainer 50, a rotary sleeve 57 and a locking cap 60 on the fixed mount 40 respectively.

Paste to inhale part 30 and comprise that soft flat subsides inhale sheet 31, and one inhales the sheet center and vertically stretches the column of establishing 32 from pasting.

Fixed mount 40 comprise one be used to compress paste inhale sheet 31 compress dish 41 and one sleeve 43 that is sheathed on the column 32.The lower end edge of sleeve 43 axially is formed with stroke groove 42, the upper end closed of sleeve 43.The upper surface of sleeve 43 has extended upward a boss 44.

Edge type strainer 50 is cylindrical, is formed with camb contour 51 on its upper surface, is formed with the delay tank 53 of depression at the height point of camb contour 51.

Rotary sleeve 57 is tubular, and its periphery is heaved, and forms some planes 58 that make things convenient for people's manual manipulation on the outer peripheral face.

Be formed with grab 61 on the locking cap 60, be used for being connected with supporting part 70.

When this adsorption site 20 of assembling, the first step places sleeve 43 with spring 56, sleeve 43 is enclosed within on the column 32 again, makes spring 56 between the top and column 32 of sleeve 43.Second step, edge type strainer 50 is placed on the sleeve 43, an end of some dead mans 55 is passed stroke groove 42 on the sleeve 43, enter the hole 33 on the column 32, thereby captive joint with column 32, the camb contour 51 of the other end of dead man 55 and edge type strainer 50 contacts and cooperates.The 3rd step was placed in rotary sleeve 57 on the edge type strainer 50, and the card key 52 on draw-in groove on the inside face of rotary sleeve 57 (figure does not show) and the edge type strainer 50 cooperates, and rotated thereby the rotation of rotary sleeve 57 can drive edge type strainer 50.The 4th step was installed on the top of sleeve 43 with locking cap 60, and screw (figure does not show) passes hole 62 on the locking cap 60 and the hole 45 on the boss 44, and locking cap 60 is fixed on the sleeve 43.

When using, the user can place adsorption site 20 on the flat carrier (for example glass) earlier, guarantees to paste and inhales sheet 31 and flat carrier applying, pastes to inhale sheet 31 and compress dish 41 and separates, and this moment, dead man 55 was positioned at the low spot of the camb contour 51 of edge type strainer 50.Then, rotate rotary sleeve 57, driving edge type strainer 50 rotates, edge type strainer 50 orders about the dead man 55 and column 32 upward movements of captiveing joint with dead man 55 on camb contour 51, the edge that compresses dish 41 props up to paste inhales sheet 31, column 32 pullings are pasted the middle part of inhaling sheet 31 and are made progress, thereby form vacuum, and instrument base 10 promptly is adsorbed on this flat carrier.This moment, dead man 55 was arranged in delay tank 53, prevented from not rotate under the situation of rotary sleeve 57 the user, and dead man 55 and column 32 move downward automatically and make absorption unclamp.When desiring removal, rotatable rotary sleeve 57 drives edge type strainer 50 and rotates, and the elastic force of spring 56 and gravity combined action make that the dead man 55 on camb contour 51 moves downward with the column 32 of captiveing joint with dead man 55, make and to take off this instrument base 10 by the vacuum expendable pattern that forms.
