Embodiment

Two embodiment that below enumerate now in the utility model preferred embodiment implement according to this for affiliated technical field those of ordinary skill.

See also Fig. 1, it is among first embodiment of the utility model preferred embodiment, the three-dimensional structure diagram of casing fastening structure.As shown in the figure, casing fastening structure of the present utility model is applicable to snapping one first housing 1 and one second housing 2, and having a removal hole 11 on first housing 1 stretches out for an actuator of inside (showing among Fig. 1), perhaps the rigid object 200 that supplies a size can enter removal hole 11 stretches into removal hole 11, in order to second housing 2 is removed from first housing 1.Wherein, rigid object 200 can be a yi word pattern screwdriver.In the utility model preferred embodiment, first housing 1 is a plate object, and a triangle plate body is extended at the plate object two ends separately, and removal hole 11 is opened in the central authorities of plate object.2 of second housings are a ridge moulding, are engaged in the below of first housing 1.

See also Fig. 2, and see also Fig. 3.Fig. 2 and Fig. 3 are respectively among first embodiment of the utility model preferred embodiment, the schematic diagram of the decomposing schematic representation of casing fastening structure and second housing.As among Fig. 2 up and down in contrast to shown in the visual angle of Fig. 1, casing fastening structure of the present utility model comprises three pliability trips 12, four fairleads 13, a catch element 3, and one from catch element 3 extended actuators 34.As shown in Figure 3, casing fastening structure of the present utility model also comprises three snapping trips 21, and these a plurality of snapping trips 21 are that the medial surface by second housing 2 extends downwards.

Pliability trip 12 and fairlead 13 are that the medial surface from first housing 1 extends upward and is staggered, and are adjacent to removal hole 11 one of in the pliability trip 12.Catch element 3 is a plate object, offers three first draw-in grooves 31, three second draw-in grooves 32 and four spacing guide channels 33 on it.Wherein, on the position, first draw-in groove 31 is that to correspond respectively to pliability trip 12, the second draw-in grooves 32 be to correspond respectively to snapping trip 21, and spacing guide channel 33 corresponds respectively to fairlead 13.Actuator 34 extends towards removal hole 11, can be a plate object vertical with catch element 3, and the side that is close to removal holes 11 from catch element 3 extends and be one-body molded with catch element 3.

See also Fig. 4, it is among first embodiment of the utility model preferred embodiment, and the generalized section of casing fastening structure is the AA sectional schematic diagram among Fig. 1 simultaneously.As shown in Figure 4, first housing 1 and second housing 2 under the state of snapping combination, first draw-in groove 31 of pliability trip 12 towards a first direction I1 trip in catch element 3, and second draw-in groove 32 of snapping trip 21 towards a second direction I2 trip in catch element 3.Wherein, second direction I2 is opposite with the direction of first direction I1.Simultaneously, in the present embodiment, actuator 34 extends to contiguous removal hole 11 places.

Then, see also Fig. 5, it is among first embodiment of the utility model preferred embodiment, the illustrative view of casing fastening structure.As shown in Figure 5, second housing 2 is dismantled from first housing 1, rigid object 200 can be inserted removal holes 11, utilize rigid object 200, also move towards second direction I2 so as to driving catch element 3 towards this actuator 34 of second direction I2 pushing tow when desire.

See also Fig. 6, it is the fairlead of casing fastening structure of the utility model preferred embodiment and the schematic diagram of spacing guide channel.As shown in Figure 6, spacing guide channel 33 is to offer along the path RW that trips, be placed through in the spacing guide channel 33 from first housing, 1 extended fairlead 13, and offer a fixed card slot 131 on the fairlead 13, to be sticked in an end of spacing guide channel 33 by fixed card slot 131.When catch element 3 is driven by actuator 34 and when second direction I2 moved, fairlead 13 can move on the catch element 3 spacing spacing strokes in the path RW that trips, and makes mobile route be unlikely to oblique distortion.

Please later consult Fig. 5.When catch element 3 moves along the path RW that trips towards second direction I2, because pliability trip 12 tool pliabilities can not hinder moving of catch element 3 to second direction I2 bending along catch element 3.At this moment, because snapping trip 21 is buckled in second draw-in groove 32 towards second direction I2, when second draw-in groove 32 moves towards second direction I2, snapping trip 21 can get loose from second draw-in groove 32.So, second housing 2 upwards can be removed from first housing 1.

Then, see also Fig. 7 and Fig. 8, it is respectively among second embodiment of the utility model preferred embodiment, the generalized section of casing fastening structure and illustrative view.As shown in Figure 7, in the present embodiment, actuator 34 ' extends towards removal hole 11 ' from catch element 3, and one the tunnel extends removal hole 11 ' outside.Because actuator 34 ' exposes to first housing 1, so when user's desire is triped casing fastening structure of the present utility model, can directly utilize finger to promote actuator 34 ' towards second direction I2.As shown in Figure 8,, also can drive catch element 3 and move, produce, second housing 2 is upwards removed from first housing 1 as the start process among first embodiment along the path RW that trips when actuator 34 ' moves towards second direction I2.

After first housing 1 and second housing 2 are assembled by the mode of screw lock or traditional snapping in the prior art, can have and be difficult to the problem dismantling even can't dismantle, above-mentioned effect by casing fastening structure of the present utility model, but the doubt that first housing 1 and second housing, 2 disassembled simplies and avoiding damage benefits to product manufacturing and maintenance aspect.

Certainly; the utility model also can have other various embodiments; under the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection range of the appended claim of the utility model.
