Specific embodiment
As shown in Figure 1, Figure 4 and Figure 5, a kind of O-ring seal 10, comprising:
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 increase the tensile strength of O-ring seal 10 significantly.It is apparent that the hardness and drawing of support frame 101
It stretches intensity and is better than colloid 102, when support frame 101 is more and colloid 102 is less, the hardness of O-ring seal 10 is larger, when
The hardness of O-ring seal 10 is smaller when support frame 101 is less and colloid 102 is more.So the hardness of O-ring seal 10 is logical
The ratio of the support frame 101 and the colloid 102 is crossed to adjust.In addition, working as 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 of fiber silk structure 101 is big.
When the diameter of O-ring seal 10 is smaller, large volume of support frame 101 can not be accommodated, can only be used at this time
A piece silk thread 101c is surrounded as closed annular and is become support frame 101, and colloid 102 is attached on silk thread 101c at this time.
When O-ring seal 10 is when being relatively large in diameter, support frame 101 can be used at least two silk thread 101c and be woven to envelope
The annular closed forms, as shown in Figure 6.Necessarily there is between each silk thread 101c gap at this time.Colloid 102 is filled in gap
Interior and be attached on each silk thread 101c, such colloid 102 substantially fills support frame 101 full, has prevented support frame 101
It is interior that there are the possibility of air or bubble.
In the embodiment depicted in figure 2, the quantity of the silk thread 101c at 10 center of O-ring seal is more, such O
Type sealing ring 10 is the structure gradually increased from outer surface to core rigidities, is mentioned by the O-ring seal 10 in compression process
What is supplied is the elastic force gradually increased.And only with the O-ring seal 10 of a silk thread 101c, glue is provided in compression process
The biggish elastic force of the lesser elastic force of body portion and the part silk thread 101c.
In the embodiment shown in fig. 3, the silk thread 101c being distributed in colloid 102 is more uniform, by O-shaped close in compression process
The relative constant elastic force that seal 10 provides.
The application also provides the manufacturing method of O-ring seal 10 shown in a kind of Fig. 2, Fig. 3 and Fig. 6, includes the following steps:
A1 is woven into long rope using multi-filament line 101c.
Long rope is surrounded the support frame 101 of annular by A2.
Support frame 101 is placed in the shaping mould of annular by A3.
A4, it is in the gap that colloid 102 is injected shaping mould to be filled in colloid 102 between each silk thread 101c and each
On silk thread 101c.
A5 makes the colloid 102 in shaping mould be formed by curing O-ring seal 10.
As shown in figure 4, an annular silk screen 101a serves as the support frame in one embodiment of the application
101, the silk screen 101a are woven by least two silk thread 101c, are had on the silk screen 101a and are compiled by the silk thread 101c
Hole 101b is woven made of knitting；The colloid 102 is filled in the braiding hole 101b and on each silk thread 101c.Fig. 5
The situation of two braiding hole 101b filling colloids 102 is illustrated only, colloid should all be filled in actually all braiding hole 101b
102。
The application also provides a kind of manufacturing method of O-ring seal 10 shown in Fig. 5, comprising:
B1 is woven into the silk screen 101a with braiding hole 101b, the center tool of silk screen 101a using multi-filament line 101c
There is circular hole.
Silk screen 101a is placed in the shaping mould of annular by B2.
B3, each silk screen 101a's that colloid 102 is injected shaping mould to be filled in colloid 102 in support frame 101
It weaves in the 101b of hole and on each silk thread 101c.
B4 makes the colloid 102 in shaping mould be formed by curing O-ring seal 10.
In one embodiment of the application, silk thread 101c is wire, can be suitable for height in this way for O-ring seal 10
Warm environment or the biggish environment of tensile strength are ready.In another embodiment of the application, the silk thread 101c is fibre
Silk is tieed up, fiber filament can reduce the value added of 10 hardness of O-ring seal compared to wire.In one embodiment, work as fiber filament
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 range of O-ring seal 10.
In the outer surface of support frame 101, cured colloid 102 forms outer colloid layer, in one unshowned reality of the application
It applies in example, O-ring seal 10 includes silver coating, which 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 by 10 entirety of O-ring seal
Corrosion-resisting function.In one embodiment of the application, silver coating with a thickness of 0.2mm-0.5mm.
So far, although showing those skilled in the art will appreciate that the multiple of the application have been shown and described in detail herein
Example property embodiment still, still can be direct according to present disclosure in the case where not departing from the application spirit and scope
Determine or deduce out many other variations or modifications for meeting the application principle.Therefore, scope of the present application is understood that and recognizes
It is set to and covers all such other variations or modifications.
