The invention will be further described below in conjunction with the accompanying drawings.
As shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the present invention is made up of housing 1, lock device 2 and convex plug 3 etc., in the shell
Two necks 11 are arranged with the side wall of the side of body 1, are also arranged with two breach 12 on the end face of the homonymy of housing 1, two
The circumferencial direction uniform intervals of the individual neck 11 and breach 12 along housing 1 are set；Outside two corresponding housings 1 of breach 12
The opening position of side wall combines provided with inverted sections, and the inverted sections combination includes the first vertical section 131 and the second vertical section 132,
It is provided with horizontal segment 133 between two vertical sections, the lower end of the both ends of the horizontal segment 133 respectively with two vertical sections connects
Connect, the correspondence position formation one of first vertical section 131, the second vertical section 132, horizontal segment 133 and the lateral wall of housing 1 is opened
Mouthful groove, the upper end notch of the open slot is towards breach 12.
Two the first elastic clamping blocks 21, two first elastic cards are integrally arranged with the lower end of the lock device 2
Block 21 is structure wide at the top and narrow at the bottom, and the upper end of first elastic clamping block 21 abuts fixation with the upper end cell wall of neck 11；In the lock
Only the upper end of device 2 is integrally arranged with two the second up-narrow and down-wide elastic clamping blocks 22, two second elastic clamping blocks 22
Upper end is equipped with one section of outwardly directed flat segments 221, and the external part of the flat segments 221 is equipped with one section of bending extended downwardly
Section 222, second elastic clamping block 22, flat segments 221 and the bending segment 222 of correspondence position form a card buckle-like structure, should
Card buckle-like structure is connected to corresponding to the opening position of breach 12 in the side wall of housing 1, and the bending segment 222 is stretched into open slot.
One section of boss 23, the correspondence position of the boss 23 and the lateral wall of housing 1 are provided with the madial wall of the bending segment 222
Abut, the bottom of the madial wall of bending segment 222 is provided with one section of inclined-plane wide at the top and narrow at the bottom, under the upper end on the inclined-plane and boss 23
End connection.
Stopper slot 31, two second elastic clamping blocks 22 and stopper slot 31 are provided with the lateral wall of the convex plug 3
Connect and fix, fixing lug boss 32 is provided with the circumferencial direction of the upper end edge convex plug 3 of the stopper slot 31.
Sealing ring 4 is embedded with the housing 1, when the lock device 2 connects and fixes with housing 1, the lower end of lock device 2
Face abuts with the upper surface of sealing ring 4；When the convex plug 3 connects and fixes with lock device 2, the upper surface of lock device 2 is with consolidating
It is 2mm to determine the spacing between the lower surface of boss 32.
The application method of the present invention is as follows：
As shown in Fig. 1 to Fig. 4, coaxial direction of the lock device 2 along the installation site of housing 1 is installed, 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 narrow the first wide elastic clamping block 21 stepped housing 1 completely under two reaches the position of neck 11
When, the extruding force that side wall applies slowly releases, and the Rapid reset under the effect of two fixture block natural resiliencies, now the upper end of neck 11 is interior
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 surface abuts with the upper surface of sealing ring 4.
Then, after the surface of convex plug 3 being cleaned and lubricated, along the coaxial direction of the installation site of housing 1 to locking
Grafting in device 2, when convex plug 3 contacts with the second up-narrow and down-wide elastic clamping block 22, acted on using the elastomeric material of part, the
Two elastic clamping blocks 22 are slowly outwards strutted in the case where being acted on by external force, and breach 12 just provides the space 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 chamber of housing 1), and now, the second elastic clamping block 22 is moved to limit
The position opening position of groove 31, the second elastic clamping block 22 Rapid reset under natural resiliency effect, flat segments 221 and the end face at breach 12
Abut, 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, now the lower surface of the second elastic clamping block 22 abuts the bottom land of stopper slot 31, so as to play to plug-locking retaining；Sun is inserted
First 3 with lock device 2 connect and fix when, the spacing between the upper surface and the lower surface of fixing lug boss 32 of lock device 2 is 2mm.
When needing to take apart, while the lower end of two bending segments 222 is pinned, be fulcrum with the boss 23 of corresponding end, utilize thick stick
Rod principle, bending segment 222 is pressed to the direction of housing 1, flat segments 221 and leaned against at the breach 12 of housing 1, the upper end of bending segment 222
Flat segments 221 are pulled out, flat segments 221 drive the upper end of the second elastic clamping block 22 to be turned out strutting in the counterclockwise direction,
Lower end rotates obliquely to the middle part of housing 1 in the counterclockwise direction, i.e. the second elastic clamping block 22 departs from stopper slot 31, takes out convex plug
3；Then, the first elastic clamping block 21 is extruded, the second elastic clamping block 22 is departed from out of neck 11, lock device 2 also realizes dismounting.
The inserting end of lock device 2 has to abut sealing ring 4, so, sealing ring 4 is stretched into the inserting end of convex plug 3
It when following, can just play a part of secondary seal protection, and can prevent foreign matter from entering, ensure safe handling.
The undescribed part of the invention is identical with the prior art, and therefore not to repeat here.
Embodiments of the present invention are these are only, are not intended to limit the scope of the invention, it is every to utilize the present invention
The equivalent structure that specification and accompanying drawing content are made, other related technical areas are directly or indirectly used in, similarly at this
Within the scope of patent protection of invention.
