Card buckle-like structure is connected at 12 position of notch on corresponding 1 side wall of housing, and the bending segment 222 is stretched into open slot.
One section of boss 23, the corresponding position of the boss 23 and 1 lateral wall of housing are equipped in the madial wall of the bending segment 222
Abut, the lower part of 222 madial wall of bending segment is equipped with one section of inclined-plane wide at the top and narrow at the bottom, the upper end on the inclined-plane under boss 23
End connection.
Limiting slot 31, two second elastic clamping blocks 22 and limiting slot 31 are equipped on the lateral wall of the convex plug 3
It connects and fixes, fixing lug boss 32 is equipped in the circumferencial direction of the upper end edge convex plug 3 of the limiting slot 31.
Sealing ring 4 is embedded in the housing 1, when the lock device 2 is connected and fixed with housing 1, the lower end of lock device 2
Face is abutted with the upper surface of sealing ring 4；When the convex plug 3 is connected and fixed with lock device 2,2 upper surface of lock device is with consolidating
It is 2mm to determine the spacing between 32 lower face of boss.
The application method of the utility model is as follows：
As shown in Fig. 1 to Fig. 4, lock device 2 is installed along the coaxial direction of 1 installation site of housing, when lock device 2
Two the first elastic clamping blocks 21 contacted with the side wall of housing 1, two the first elastic clamping blocks 21 in the case where being acted on by external force inwardly
Portion is compressed, when the side wall two that the first wide elastic clamping block 21 narrow under two stepped housing 1 completely reaches 11 position of card slot
When, the extruding force that side wall applies slowly releases, and the Rapid reset under the effect of two fixture block natural resiliencies, 11 upper end of card slot is interior at this time
Side wall abuts the upper surface of the first elastic clamping block 21, and retaining, at the same time, lock device 2 are locked to lock device 2 so as to play
Lower face is abutted with the upper surface of sealing ring 4.
Then, after 3 surface of convex plug being cleaned and lubricated, along the coaxial direction of 1 installation site of housing to locking
Grafting in device 2 when convex plug 3 is contacted with the second up-narrow and down-wide elastic clamping block 22, is acted on using the elastic material of part, the
Two elastic clamping blocks 22 are slowly strutted outward in the case where being acted on by external force, and notch 12 just provides the gap of resigning, when sun is inserted
First 3 grafting is in place (i.e. when the inserting end of convex plug 3 extend into the inner cavity of housing 1), at this point, the second elastic clamping block 22 is moved to limit
At slot 31 position of position, the second elastic clamping block 22 Rapid reset under natural resiliency effect, flat segments 221 and the end face at notch 12
It abuts, bending segment 222 stretches into the open slot formed by the first vertical section 131, the second vertical section 132, horizontal segment 133 and housing 1
In, the lower face of the second elastic clamping block 22 abuts the slot bottom of limiting slot 31 at this time, so as to play to plug-locking retaining；Sun is inserted
