Description

Housing assembly

Technical field

The utility model relates to a kind of housing assembly, relates in particular to a kind of housing assembly with good sealing property.

Background technology

Fig. 1 is the synoptic diagram of existing a kind of housing assembly.Please refer to Fig. 1; First housing 110 of existing housing assembly 100 and the material of second housing 120 are all plastic cement; And be provided with assembling raised line 112 on the avris of first housing 110, and the corresponding position of second housing 120 is provided with assembling groove 122, and can cause poor air-tightness because of assembling tolerance when preventing that first housing 110 and second housing 120 from fitting together; Reducing the waterproof rate, is the water proof rubber circle 130 of annular so can in assembling groove 122, place one in addition usually.

Yet water proof rubber circle 130 also is difficult for inserting in the assembling groove 122 of second housing 120, has the assembling difficulty.In addition, existing housing assembly 100 has first housing 110,

second housing

120 and 130 at least three kinds of materials and parts of water proof rubber circle and need manage and deposit.

Fig. 2 is the synoptic diagram of existing another kind of housing assembly.Please refer to Fig. 2; Existing another kind of housing assembly 200 is the cross section to be set be circular water proof rubber bar 220 on the avris of first housing 210; Then first housing 210 is pressed together on second housing 230, behind rubber-like water proof rubber bar 220 pressurizeds distortion and the space between first housing 210 and second housing 230 is sealed.Yet, damage is also arranged after water proof rubber bar 220 pressurizeds easily, or, causes the sealing effectiveness variation because get off for a long time and can harden.

The utility model content

The utility model provides a kind of housing assembly with good sealing property.

The utility model proposes a kind of housing assembly; Comprise one first housing and one second housing; First housing has one first assembling surface and second housing has one second an assembling surface and a spine, and wherein first hardness of first housing is less than second hardness of second housing, and first housing and second housing are when fitting together; The first assembling surface and the second assembling surface lean, and spine heads into the first assembling surface and the first assembling surface and spine driving fit.

In an embodiment of the housing assembly of the utility model, the cross sectional shape of above-mentioned spine is triangular pyramidal.

In an embodiment of the housing assembly of the utility model; The first above-mentioned housing has one first one and one second one, and first one is double-material jet formation with second one, and first one has first hardness; And second one have one the 3rd hardness, and the 3rd hardness is greater than first hardness.

In an embodiment of the housing assembly of the utility model, one of them of first housing and second housing has a plurality of fixedly trips, and first housing and second housing wherein another has a plurality of openings, and fixedly the trip correspondence is fastened on opening.

In an embodiment of the housing assembly of the utility model, also comprise and pass a plurality of screws that first housing is locked second housing.

Based on above-mentioned; In the housing assembly of the utility model, because second housing is provided with spine, and the part that first housing contacts with second housing is used softer material; So when first housing and second housing fit together; Spine can head in the first assembling surface of first housing, and first housing can be because of heading into of spine be out of shape adapting to the shape of spine, and with the second housing driving fit.

For letting the above-mentioned feature and advantage of the utility model can be more obviously understandable, hereinafter is special lifts embodiment, and conjunction with figs. elaborates as follows.

Embodiment

Fig. 3 is the synoptic diagram of the housing assembly of the utility model one embodiment.Housing assembly 300 comprises one first housing 310 and one second housing 320; First housing 310 has one first assembling surface 312; And second housing 320 has one second assembling surface, 322 and one spine 324; Wherein first hardness of first housing 310 is relatively less than second hardness of second housing 320; And first housing 310 and second housing 320 be when fitting together, and the 312 and second assembling surface 322, the first assembling surface leans, and spine 324 heads into the first assembling surface 312 and the first assembling surface 312 and spine 324 driving fits.

Please continue with reference to figure 3, with present embodiment, first housing 310 has one first one 314 and 1 second one 316; And first one 314 and second ones 316 is to form first housing 310 with double-material jet formation; Wherein first one 314 material can be relative softer materials such as rubber, and has the first above-mentioned hardness, and second one 316 material is relative harder materials such as plastic cement; And have one the 3rd hardness, and second one 316 the 3rd hardness is greater than first one 314 first hardness.In addition, the first assembling surface 312 promptly is to be positioned at first one 314, and the cross sectional shape of spine 324 is triangular pyramidal.Again, the material of second housing 320 can be identical with second one 316 of first housing 310, and meaning i.e. second hardness can be same as the 3rd hardness.Certainly, the material of second housing 320 also can be to be different from second one 316 of first housing 310, and meaning i.e. second hardness is different from the 3rd hardness, and second housing 320 and first housing 310 second one 316 who hard who softly determine according to the actual design demand.

In detail, when first housing 310 and second housing 320 were fitted together, assembler placed first housing 310 on second housing 320; So that the 312 and second assembling surface 322, the first assembling surface leans; And because first one 314 first hardness is minimum, under first one 314 situation of exerting pressure each other with spine 324, spine 324 heads in the first assembling surface 312; And first one 314 be out of shape meeting the shape of spine 324 gradually, and the first assembling surface 312 and spine 324 driving fits.By the setting of spine 324 and first one 314 distortion, can reach and let the effect of the first assembling surface 312 and spine 324 complete driving fits and then the waterproof ability of enhancement housing assembly 100.

Hold above-mentioned; First housing 310 also can have a plurality of fixedly trips 318, and second housing 320 also can have a plurality of openings 326 accordingly, and fixedly trip 318 correspondences are fastened on opening 326; So that the relative position of first housing 310 and second housing 320 is fastened to each other, show like Fig. 4.

With reference to figure 4, in order to increase the assembling steadiness of first housing 310 and second housing 320, housing assembly 300 also can comprise a plurality of screws 330 equally, and these screws 330 pass first housing 310 and lock in second housing 320.

The first above-mentioned housing 310 and the fixed form of second housing 320 are by the corresponding manner of fixing trip 318 and opening 326; Or the mode that locks with screw 330; Can select wherein a kind ofly, perhaps fasten and lock dual mode and all use like present embodiment.

In sum; In the housing assembly of the utility model; Because be arranged on the first assembling surface that spine on second housing can head into first housing; And the first assembling surface can corresponding spine shape and be out of shape so that the surperficial driving fit of first assembling is in spine, and do not have the space between the first assembling surface and the spine.So, first housing and second housing be complete driving fit together, housing assembly has good driving fit and waterproof effect.

Though the utility model discloses as above with embodiment, so it is not in order to limiting the utility model, any under the those of ordinary skill of technical field, when can doing a little change and retouching, and do not break away from the spirit and the scope of the utility model.
