Fig. 2 is the structural representation after the part assembling of combined shell in Fig. 1, refers to Fig. 2.

Projection 222 is provided with cover body 200 on the outer surface of opening.Specifically, projection 222 is arranged on snap ring 220 Outer peripheral face on.The quantity of projection 222 is three, and projection 222 is spaced uniform arrangement.It is corresponding, the second through hole of base shell 300 The otch 330 through the second through hole 320 for projection 222 is offered on 320 inwall.

The side of cover body 200 is provided with block 340 in the second through hole 320 in base shell 300.Specifically, block 340 The lower section of otch 330 is arranged on i.e. away from the side of cover body 200, the shape of block 340 extends to the center of the second through hole 320. Cover body 200 inserted and will contradict after the second through hole 320 on block 340, to determine the position in the insertion base shell 300 of cover body 200.

The process that cover body 200 is assembled with base shell 300 is as follows：It is convex during cover body 200 inserts the second through hole 320 Block 222 is passed through from otch 330, until the edge of cover body 200 touches block 340；Then, the rotation of opposite base shell 300 cover body 200, projection 222 is then held in the inside of base shell 300, prevents cover body 200 from departing from from base shell 300.When cover body 200 it is relative When base shell 300 rotates to an angle, locking mechanism 400 is just fastened in the hole clipping 221 of cover body 200, with prevent cover body 200 with Base shell 300 relatively rotates again, so as to ensure that cover body 200 is securely attached in base shell 300.

Fig. 3 is the structural decomposition diagram of locking mechanism, refers to Fig. 3.

Locking mechanism 400 includes press section 410, driving section 420, buckle 430 and elastic component.Elastic component includes that first is elastic The elastic component 450 of part 440 and second, the first elastic component 440 and the second elastic component 450 are spring.One end of driving section 420 with press Splenium 410 connects, and the other end of driving section 420 is fixedly connected with buckle 430, and pressing press section 410 drives driving section 420 to move Dynamic, the first elastic component 440 and the second elastic component 450 be arranged on driving section 420, for making driving section 420 reset.

Stretch out in first through hole 310 (as shown in Figure 1) of the press section 410 from base shell 300, in order to control buckle 430 locus.The geomery of buckle 430 is consistent with the geomery of hole clipping 221 (as shown in Figure 1), to ensure buckle 430 can be fastened in hole clipping 221.First elastic component 440 and the second elastic component 450 are clamped in the side wall of base shell 300 and pass Between dynamic portion 420.

Fig. 4 is driving section and the structural representation after snap assembled, refers to Fig. 4.

Driving section 420 includes transmission main body 421, first baffle 422 and second baffle 423.Transmission main body 421 is strip, First baffle 422 and second baffle 423 are respectively perpendicular the both sides for being arranged on transmission main body 421.

First elastic component 440 and the second elastic component 450 are separately positioned on first baffle 422 and second baffle 423 and equal Length direction along transmission main body 421 extends.Side on first baffle 422 towards the first elastic component 440 is provided with the first limit Position pillar 424, the first elastic component 440 is set on the first spacing pillar 424, to prevent the first elastic component 440 from driving section 420 On come off.Side on second baffle 423 towards the second elastic component 450 is provided with the second spacing pillar 425, the second elastic component 450 are set on the second spacing pillar 425, to prevent the second elastic component 450 from coming off from driving section 420.

Buckle 430 is L-type shape, and one end of buckle 430 is vertically connected in transmission main body 421 away from press section 410 One end, the other end of buckle 430 is parallel and arranges towards transmission main body 421.Buckle 430 rises towards one end of transmission main body 421 To the effect engaged with hole clipping 221.To improve the fastness of engaging, in the present embodiment, one end of snap action is played on buckle 430 Outer peripheral face along cover body 200 (as shown in Figure 1) extends certain length, to increase the length of the engaging with hole clipping 221 of buckle 430.

Transmission main body 421 is additionally provided with transmission inclined-plane 426 away from one end of buckle 430.Transmission inclined-plane 426 be used for bear by The pressing force of splenium 410, so that the side shifting that transmission main body 421 is located to buckle 430.

Fig. 5 is the structural representation of press section and driving section, refers to Fig. 5.

Press section 410 includes pressing main body 411, pressing inclined-plane 412, the first spacing preiection 413 and the second spacing preiection 414.Pressing main body 411 is column.

After press section 410 coordinates with driving section 420, pressing main body 411 is connected in transmission main body 421 (as shown in Figure 1) Away from one end of buckle 430, main body 411 is preferably pressed perpendicular to driving section 420, to ensure to press main body 411 with transmission main body There is good power transmission effect between 421.Pressing inclined-plane 412 is arranged on pressing main body 411 near one end of transmission main body 421, Pressing inclined-plane 412 and the transmission relative sliding contact of inclined-plane 426.Press section 410 is received after pressing force, and pressing inclined-plane 412 will be acted on Power is transferred to be driven inclined-plane 426, driving section 420 is moved to the direction away from press section 410.

First spacing preiection 413 and the second spacing preiection 414 are disposed on pressing inclined-plane 412.Press section 410 and biography After dynamic portion 420 coordinates, transmission main body 421 is clamped between the first spacing preiection 413 and the second spacing preiection 414, so as to prevent Press section 410 and driving section 420 shift to install, the transmission effect of power of influence.

It is easily understood that not only can may be used also in the form of inclined-plane connection between press section 410 and driving section 420 It is with using other types of attachment, for example, the pressing main body 411 of press section 410 is flat with the transmission main body 421 of driving section 420 Row is coaxially set, meanwhile, corresponding position opens up through hole, stretches out to press main body 411 on the side wall of base shell 300 Base shell 300, such type of attachment can equally play the technique effect of inclined-plane connection.

Fig. 6 is the structural representation in Fig. 1 after the assembling completely of combined shell, refers to Fig. 6.

Cover body 200 is screwed in base shell 300, and the press section 410 of locking mechanism 400 is stretched out from the inside of base shell 300. When not pressing press section 410, the buckle 430 of locking mechanism 400 engages with the hole clipping 221 on cover body 200, and cover body 200 cannot phase Base shell 300 is rotated, cover body 200 is securely attached in base shell 300.The process of pressing press section 410, press section 410 drive driving sections 420 are moved, meanwhile, the first elastic component 440 and the second elastic component 450, driving section 420 are compressed in driving section 420 Buckle 430 is driven to depart from the hole clipping 221 on cover body 200, now rotating cover body 200 can be easily by cover body 200 from base shell Unload on 300.If not screwing off cover body 200 from base shell 300, after removing the pressure to press section 410, the first elastic component 440 Recover deformation, promote driving section 420 to reset with the second elastic component 450, driving section 420 drives buckle 430 to be embedded in hole clipping 221, Cover body 200 is set firmly to be connected again with base shell 300.

The simple structure of locking mechanism 400, easy to control, the shape that existing screw thread can be replaced to screw that the present embodiment is provided Formula.Using the combined shell of the locking mechanism, cover body can not only be made to be firmly attached with base shell integral, and kayser machine In the clearance spaces inside base shell, the outer shape for not resulting in combined shell becomes big to structure, realizes combined shell Miniaturization Design.
