[embodiment]

Consult Fig. 1, Fig. 2, the preferred embodiment that the utility model does not have the casing of screw positioning component mainly is to be used for locating an assembly 1, and this assembly 1 has the several screws 11 (as Fig. 5) that are formed on a side.This casing comprises a housing 2, a support 3 and a clamping piece 4.

This housing 2 has a upper and lower loam cake 22 and a base 23 that covers and define an accommodation space 21, be formed on an opening 24 of this loam cake 22 and these base 23 1 sides, and is formed on these loam cake 22 1 inner faces and towards the outstanding locking plate 25 of this base 23.

This support 3 has a tray 31, an on-slip part 32, one first side plate 33 and one second side plate 34, a panel 35, and two displacement aperture 36,37.This tray 31 is to be extended to this accommodation space 21 by these housing 2 openings 24.This on-slip part 32 is formed in the end 311 away from this opening 24.This first, second side plate the 33, the 34th is formed on this tray 31 both sides relatively.This panel 35 is to be formed on this first side plate 33 and contiguous these tray 31 1 ends 311 towards this tray 31.These displacement aperture the 36, the 37th are arranged, are extended along parallel this first side plate bearing of trend, and this displacement aperture 37 is towards these second side plate, 34 skews.

Ginseng Fig. 2, Fig. 3, this clamping piece 4 have lead moving plate 41, pass this

displacement aperture

36,37 and lead two spigots 42 that moving plate 41 links, be formed on this this lead moving plate 41 1 sides and towards a side pressure sheet 43 of these support 3 first side plates 33, be formed on this side pressure sheet 43 and towards a hitching post 44 of these support 3 second side plates 34, be formed on this and lead moving plate 41 opposite sides and drive sheet 45 towards one of these housing 2 openings 24, and be formed on this and lead on the moving plate 41 and be in reverse to this tray 31 upwardly extending one group of control sheets 46.

Ginseng Fig. 1, Fig. 2, when this assembly 1 is installed, need only lift and open this loam cake 22, and insert this assembly 1 by these housing 2 openings 24, this assembly 1 is slipped into towards these housing 2 accommodation spaces 21 along these support 3 trays 31, ginseng Fig. 4, Fig. 5, when this assembly 1 touches the drive sheet 46 of this clamping piece 4, can push this clamping piece 4 simultaneously and follow this

displacement aperture

36,37 displacements with this spigot 42, the deviation angle that makes this clamping piece 4 follow this displacement aperture 37, press close to this assembly 1, and place in this assembly 1 corresponding screw 11, be hampered by this on-slip part 32 to this assembly 1 with this hitching post 44.

At this moment, this assembly 1 be subject to these support 3 first,

second side plates

33,34 respectively and can't a left side, a left side rocks, be subject to this panel 35 can't upper and lowerly to rock, and be subject to this hitching post 44 and can't forward and backward slippage with this tray 31.

Ginseng Fig. 1, when covering this loam cake 22 and this base 23, this locking plate 25 can stop this group control sheet 46 just, and making this clamping piece 4 be subject to these

displacement aperture

36,37 can can't move for the stroke of displacement and this locking plate 25, whereby, reach the purpose of fixing this clamping piece 4 and locating this assembly 1.

Ginseng Fig. 1, in the time will unloading this assembly 1, need only lift and open this loam cake 22, make this locking plate 25 break away from this group control sheet 46, to remove the spacing relation of this clamping piece 4, ginseng Fig. 6, Fig. 7, at this moment, just can stir this group control sheet 46 towards these housing 2 openings 24 directions, make this clamping piece 4 follow this displacement aperture 36 with this

spigot

42,37 displacements, and push this assembly 1 with this drive sheet 45 and partly give prominence to this housing 2, at this moment, this clamping piece 4 can be followed the deviation angle skew of this displacement aperture 37 equally, make hitching post 44 break away from this assembly 1, whereby, this assembly 1 no longer is subjected to this hitching post 44 spacing, and partly outstanding this housing 2, and can make things convenient for the user that this assembly 1 is detached this support 3.

According to the above as can be known, the casing of no screwed positioning component of the present utility model () has following advantages and effect:

The utility model is by aforesaid fastening relation, in the situation that does not need instrument Lower, just can utilize simple and easy smoothly action, reach the order of installing or unloading this assembly 1 , and the element of aforementioned fastening, mostly be made of one piece, so, can simplify Fabrication schedule reduces cost, and reduces part, mould, to promote economic benefit.
