[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 two pairs of screws 11 that are formed on two sides.This casing comprises a housing 2, a support 3 and a pallet group 4.

This support 3 is to mount in this housing 2, and have the insertion end 31 and the clearing end 32 that are formed on two ends, be formed on both sides and opposed facing two conduits 33, be darted in this conduit 33 and form a reducing 34 respectively a plurality of to protuberance 35, contiguous this insertion end 31 and divide and be listed in two other fasteners 36 of this conduit 33, and contiguous this clearing end 32 and two outstanding relatively catch 37 (consulting Fig. 5) of both sides respectively.Aforementioned fastener 36 is at this

Embodiment is respectively a perforation.

This pallet group 4 is to be set on this support 3, and has two deckle boards 41, a connection piece 42, four guide grooves 43, a plurality of spigot 44.

Aforementioned deckle board 41 has formation at one end and involutory 411 of engaging with these support 3 fasteners 36, and passes a clicking section 412 of this support 3.Aforementioned involutory 411 is respectively a projection at present embodiment.

This web member 42 is to make with elastic-plastic material, and has a plurality of mouldings 421 that connect aforementioned deckle board 41.

This guide groove 43 is generally to be the L type, and has an inlet end 431 and a block end 432, and in abutting connection with a necking section 433 that this block end 432 and bore dwindle.

Aforementioned spigot 44 has an annular groove 441 respectively, is to penetrate this guide groove 43 by these guide groove 43 inlet ends 431 respectively, and is embedded in 432 at this necking section 433 and this block end with this annular groove 441, and aforementioned spigot 44 is positioned on this deckle board 41.

Ginseng Fig. 3, Fig. 4, when locating this assembly 1, need only utilize the elastoplasticity of this web member 42, pull aforementioned deckle board 41 to both sides, make aforementioned deckle board 41 drive aforementioned spigot 44 relatively away from and enlarged openings, be contained in 42 of aforementioned deckle board 41 and this web members for this assembly 1, at this moment, the web member 42 of this reinstatement be able to make aforementioned deckle board 41 abut in this assembly 1 both sides, and place in the screw 11 of this assembly 1 with aforementioned spigot 44, this assembly 1 is positioned on this pallet group 4.

When this assembly 1 is installed, this pallet group 4 need only be placed into this support 3 together with this assembly 1, make this pallet group 4 with this spigot 44 along these support guide groove 33 displacements, ginseng Fig. 4, Fig. 5, Fig. 6, when this spigot 44 is hampered by these support 3 catch 37, aforementioned spigot 44 is contained in respectively in this reducing 34 just, and involutory 411 of aforementioned deckle board 41 engages mutually with the fastener 36 of this support 3 just, at this moment, aforementioned deckle board 41 is limited by aforementioned conduit 33 respectively, aforementioned spigot 44 is limited by aforementioned protuberance 35 respectively, this pallet group 4 can't be gone up, bottom offset, and this pallet group 4 is limited by this support 3 catch 37 displacements forward, and is limited by this involutory the 411 snap-fit relationship displacement backward with this fastener 36, whereby, make this pallet group 4 obtain the location as shown in Figure 7, finish installation together with this assembly 1.

Ginseng Fig. 8, Fig. 3, in the time will unloading this assembly 1, need only upwards stir the clicking section 412 of this deckle board 41, make this involutory 411 fastener 36 that breaks away from this support 3, remove this pallet group 4 and this support 3 spacing relation backward, whereby, just can draw this clicking section 412 displacement backward, make this pallet group 4 with aforementioned deckle board 41 along aforementioned conduit 33 to this support 3 of retrolisthesis.

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 aforementioned special spacing relation, do not needing instrument Under the situation, just can utilize simple and easy smoothly action, reach and install or unload this assembly 1 Purpose, not only can simplified assembly, and convenience and simplification can promote dismounting the time
