Fig. 2 is the necklace Lossless join device overall diagram of present pre-ferred embodiments.
Specific implementation mode
In order to keep the purpose, technical scheme and advantage of the embodiment of the present invention clearer, implement below in conjunction with the present invention
Technical solution in example carries out clear, complete description, it is clear that and described embodiment is the section Example of the present invention, and
It is not all of embodiment.Based on the embodiment of the present invention, those of ordinary skill in the art are not before making the creative labor
The every other embodiment obtained is put, protection scope of the present invention is belonged to.
The necklace Lossless join device of present pre-ferred embodiments is as shown in Figure 1, simultaneously referring to Fig.2, including necklace 1 and even
Connector 2,1 both ends outer surface of necklace are both provided with annular groove 10;Connector 2 includes the first lock tube 20 and the second lock tube 21;First
Lock tube 20 and the second lock tube 21 are in semi-cylindrical, the first lock tube 20 and 21 inner wall of the second lock tube be respectively provided with there are two and annular groove
10 correspond matched semi-circular silica gel fixture block 22;First lock tube 20 is rotatably connected to stud 23, and the fixation of the second lock tube 21 is set
It is equipped with the swivel nut 24 coordinated with stud 23;Pass through the both ends of 21 teamed necklace 1 of the first lock tube 20 and the second lock tube, silica gel fixture block
22 are engaged with the annular groove 10 of 1 end outer surface of necklace, then by stud 23 and swivel nut 24 to the first lock tube 20
It is tightened with the second lock tube 21 so that there is no abrasions for 1 junction of necklace, avoid the noble metal damage that abrasion is brought
It loses, junction will not occur and be rubbed situation.
As depicted in figs. 1 and 2, spring-backed quill 25, spring-backed quill are also associated between the first lock tube 20 and the second lock tube 21
25 are set in 24 outer surface of stud 23 and swivel nut;After first lock tube 20 and the assembly of the second lock tube 21 and necklace 1, spring-backed quill
25 are in uncompressed and unstretched condition;First lock tube 20 and 21 inner wall of the second lock tube are both provided with corresponding with spring-backed quill 25
Mounting groove 3;Ensure that the first lock tube 20 and the second lock tube 21 are less prone to opposite sidesway so that more convenient when assembly, resilient sleeve
Locating part when pipe 25 is stretched into as necklace ends, and necklace ends will not be worn.
As depicted in figs. 1 and 2,25 outer surface of spring-backed quill is provided with the receiving hole 250 coordinated with 1 end of necklace;It accommodates
250 setting wide outside and narrow inside of hole;When the first lock tube 20 and the second lock tube 21 are opened, receiving hole 250 is stretched, and 1 end of necklace is stretched
After entering receiving hole 250, the first lock tube 20 and the locking of the second lock tube 21, the reinstatement of receiving hole 250 are locked 1 end of necklace, prevent
There is situations such as displacement, shake in 1 end of necklace, by receiving hole 250 and silica gel fixture block 22 respectively to the 1 end positions Liang Ge of necklace
It is positioned, both ensure that stable connection, while stabilization, anti-rotation can also be played and other effects, further reduce is ground
Damage.
As depicted in figs. 1 and 2,250 inner wall of receiving hole is provided with annular silica gel circle;Receiving hole 250 is stretched into 1 end of necklace
When, the change of annular silica gel cast is wrapped in 1 surface of necklace, further enhances the effect that is locked.
As depicted in figs. 1 and 2, the first lock tube 20 and the second lock tube 21, inner wall are both provided with non-sticky coating;Anti-wear effect
It is good.
As depicted in figs. 1 and 2,23 upper end outer surface of stud is provided with annular flange 230;Be provided on first lock tube 20 with
The through-hole 200 that stud 23 coordinates, 200 inner wall of through-hole are provided with the annular rotation slot 201 coordinated with annular flange 230.
As shown in Figure 1,23 upper end end face of stud is provided with the flat recess 231 adjusted convenient for rotation;Convenient for passing through when wearing
Nail is screwed.
As shown in Figure 1,23 upper end end face of stud is in male type arc surfaced;Facilitate adjusting.
It should be understood that for those of ordinary skills, it can be modified or changed according to the above description,
And all these modifications and variations should all belong to the protection domain of appended claims of the present invention.
