Embodiment
As shown in Figure 1, Figure 4 and Figure 5, a kind of O-ring seal 10, including：
The support frame 101 of annular and the colloid 102 being solidificated on the support frame 101, support frame 101 are closing
Cyclic structure, the structure can significantly increase the tensile strength of O-ring seal 10.It is apparent that hardness and the drawing of support frame 101
Stretch intensity and be better than colloid 102, the hardness of O-ring seal 10 is larger when support frame 101 is more and colloid 102 is less, when
Support frame 101 is less and during more colloid 102 O-ring seal 10 hardness it is smaller.So, the hardness of O-ring seal 10 is led to
The support frame 101 is crossed with the ratio of the colloid 102 to adjust.In addition, when the ratio of support frame 101 and colloid 102
When determining, the hardness of O-ring seal 10 can also be adjusted by individually adjusting support frame 101, such as metal wire structure
Hardness of the support frame 101 significantly than the support frame 101 of fiber silk structure is big.
When the diameter of O-ring seal 10 is smaller, it is impossible to accommodate large volume of support frame 101, now can only use
A piece silk thread 101c surrounds turns into support frame 101 for the annular of closing, and now colloid 102 is attached on silk thread 101c.
When O-ring seal 10 is when being relatively large in diameter, support frame 101 can use at least two silk thread 101c to be woven to envelope
The annular closed is formed, as shown in Figure 6.Now necessarily there is gap between each silk thread 101c.Colloid 102 is filled in gap
Interior and be attached on each silk thread 101c, such colloid 102 is basic to fill full by support frame 101, has prevented support frame 101
Inside leave the possibility of air or bubble.
In the embodiment depicted in figure 2, the quantity closer to the silk thread 101c of the center of O-ring seal 10 is more, such O
Type sealing ring 10 is a gradually increased structure from outer surface to core rigidities, is carried by the O-ring seal 10 in compression process
What is supplied is gradually increased elastic force.And only with silk thread 101c O-ring seal 10, glue is provided in compression process
The larger elastic force of the less elastic force of body portion and silk thread 101c parts.
In the embodiment shown in fig. 3, the silk thread 101c of distribution is more uniform in colloid 102, by O-shaped close in compression process
The elastic force for the relative constancy that seal 10 is provided.
The application also provides the manufacture method of O-ring seal 10 shown in a kind of Fig. 2, Fig. 3 and Fig. 6, comprises the following steps：
A1, long rope is woven into using multi-filament line 101c.
A2, long rope is surrounded the support frame 101 of annular.
In A3, the shaping mould that support frame 101 is positioned over to annular.
A4, it is in the gap that colloid 102 is filled between each silk thread 101c and each to make that colloid 102 is injected into shaping mould
On silk thread 101c.
A5, makes the colloid 102 in shaping mould solidify to form O-ring seal 10.
As shown in figure 4, in one embodiment of the application, an annular silk screen 101a serves as the support frame
101, the silk screen 101a are formed by least two silk thread 101c braidings, are had on the silk screen 101a and are compiled by the silk thread 101c
The braiding hole 101b knitted；The colloid 102 is filled in the braiding hole 101b and on each silk thread 101c.Fig. 5
Illustrate only in the situation that two braiding hole 101b fill colloid 102, actually all braiding hole 101b all should fill colloid
102。
The application also provides a kind of manufacture method of O-ring seal 10 shown in Fig. 5, including：
B1, the silk screen 101a with braiding hole 101b, silk screen 101a center tool are woven into using multi-filament line 101c
There is circular hole.
In B2, the shaping mould that silk screen 101a is positioned over to annular.
B3, injects shaping mould to make each silk screen 101a's that colloid 102 is filled in support frame 101 by colloid 102
Weave in the 101b of hole and on each silk thread 101c.
B4, makes the colloid 102 in shaping mould solidify to form O-ring seal 10.
In one embodiment of the application, silk thread 101c is wire, so can be applied to height for O-ring seal 10
Warm environment or the larger environment of tensile strength are ready.In another embodiment of the application, the silk thread 101c is fibre
Silk is tieed up, filament can reduce the value added of the hardness of O-ring seal 10 compared to wire.In one embodiment, filament is worked as
Quantity it is more when O-ring seal 10 it is partially hard, when filametntary negligible amounts, O-ring seal 10 is partially soft, thus can root
The soft or hard degree of O-ring seal 10 is adjusted according to filametntary quantity, to adjust the compression strength scope of O-ring seal 10.
The colloid 102 solidified in the outer surface of support frame 101 forms outer colloid layer, in one unshowned reality of the application
Apply in example, O-ring seal 10 includes silver coating, the silver coating is coated on outer colloid layer and closes the outer colloid layer.Plating
On the one hand silver layer can increase the hardness and tensile strength of O-ring seal 10, on the other hand can increase the entirety of O-ring seal 10
Corrosion-resisting function.In one embodiment of the application, the thickness of silver coating is 0.2mm-0.5mm.
So far, although those skilled in the art will appreciate that detailed herein have shown and described the multiple of the application and show
Example property embodiment, still, still can be direct according to present disclosure in the case where not departing from the application spirit and scope
It is determined that or deriving many other variations or modifications for meeting the application principle.Therefore, scope of the present application is understood that and recognized
It is set to and covers other all these variations or modifications.
