The utility model proposes a kind of silica gel sealing structure in fact, please refers to Fig. 1, and the silica gel sealing structure includes shell
And lid, the shell are equipped with installation cavity 30, the installation cavity 30 is interference fitted with the lid 20, in the installation cavity 30
Equipped with silica gel sealing ring 10, the silica gel sealing ring 10 is pressed on institute when the lid 20 is interference fitted with the installation cavity 30
It states between installation cavity 30 and the lid 20, there is groove 11, the silica gel sealing ring 10 is in mistake on the silica gel sealing ring 10
Be full of cooperation when, the groove 11 is oppositely arranged with 30 bottom wall of installation cavity at interference position to compensate magnitude of interference.
Technical solutions of the utility model are by using increasing groove 11 on silica gel sealing ring 10 to supplement the side of magnitude of interference
When needing to do encapsulation process at certain interference position, which is put into the installation cavity 30 of interference position for formula,
And lid 20 is inserted into the installation cavity 30.The lid 20 with the installation cavity 30 when being interference fitted, to described
Silica gel sealing ring 10 causes to squeeze, and silica gel have superior elasticity deformation characteristic, when the rubber seal 10 is extruded by
The pressure of the lid 20 can be resolved into horizontal force in 11 structure of groove, so that the rubber seal 10 is to surrounding
Spread out so that silica gel sealing ring 10 through interference fit operation when the condition of high temperature after, i.e., in the condition of high temperature
Lower rubber seal 10 may cause a degree of atrophy, and silica gel sealing ring 10 can be supplemented by way of dispersing outward
Magnitude of interference.In order to improve the compatibility of the silica gel sealing structure, the installation cavity 30 can be prototype or rectangular etc..It can
To understand, the groove 11 needs in interference fit and fits in groove 11 on 30 bottom wall of installation cavity, that is, need to make
The vertex for obtaining the groove 11 sustains the lid 20 and is assembled on the installation cavity 30 to pressure caused by the rubber seal 10
Power or load force.
Specifically, please referring to Fig. 1, the groove 11 is arcuate recess, arc groove or the rectangular recess of rule.Utilize arch
Groove 11 is set as the arch of rule by the principle of shape effect, so that working as lid 20 during the depression process, which can
It is significantly more efficient that the load force for bearing the lid 20 is decomposed into horizontal pull, so that rubber seal 10 can be to week
It encloses and spreads out, so that the magnitude of interference of the rubber seal 10 is made up, to improve waterproof or dust-proof effect.It is appreciated that
The groove 11 includes but is not limited to above structure, can also be other structures such as round rectangle, ellipse.
Specifically, please referring to Fig. 1, the arcuate recess position is corresponding with 20 depressed position of lid.When rubber is close
Seal 10 disperses unevenly to cause the magnitude of interference of certain side insufficient, can reduce the waterproof performance of the rubber seal 10.In order to make
Rubber seal 10 can be evenly dispersed around, and the position of arcuate recess can be arranged in the underface of lid 20, thus
The arcuate recess is set uniformly to disperse the load force suffered by it around, so that the rubber seal 10 be avoided to disperse
Non-uniform problem, to improve its waterproof performance.
As one embodiment, Fig. 1 is please referred to, by silica gel sealing ring 10 being arranged at interference position to improve waterproofness
Can, implement process are as follows: the silica gel sealing ring 10 is put into the installation cavity 30 of interference position, and lid 20 is inserted into
Into the installation cavity 30.The lid 20 makes the silica gel sealing ring 10 when being interference fitted with the installation cavity 30
At extruding, and silica gel has the characteristic of superior elasticity deformation, when the rubber seal 10 is extruded due to 11 structure energy of groove
It is enough that the pressure of the lid 20 is resolved into horizontal force.Meanwhile arcuate recess is set by the groove 11, utilize arch effect
Principle, which significantly more efficient can be decomposed into horizontal pull for the load force for bearing the lid 20 so that
Rubber seal 10 can spread out to surrounding, so that high temperature of the silica gel sealing ring 10 when by interference fit operation
After state, i.e., rubber seal 10 may cause a degree of atrophy at high operating temperatures, can be by the side that disperses outward
Formula is to supplement the magnitude of interference of silica gel sealing ring 10.In above process, if rubber seal 10 disperses unevenly, to cause a certain
The magnitude of interference of side is insufficient, can reduce the waterproof performance of the rubber seal 10.Therefore, in order to enable rubber seal 10 to four
Week is evenly dispersed, the position of arcuate recess can be arranged in the underface of lid 20, to keep the arcuate recess uniform
The load force dispersed suffered by it around, to avoid the rubber seal 10 from dispersing non-uniform problem, to improve
Its waterproof performance.It is appreciated that the groove 11 needs in interference fit and groove 11 is made to fit in 30 bottom of installation cavity
On wall, i.e., it is required that the vertex of the groove 11 sustains the lid 20 is assembled on the installation cavity 30 to the rubber seal
Pressure or load force caused by circle 10.
As a kind of deformation embodiment, Fig. 1-3 is please referred to, the silica gel sealing ring 10 can also be hollow structure, described
Groove 11 is arranged around the edge bottom of the silica gel sealing ring 10.Since the planform of silica gel sealing structure is different,
In order to be adapted with the silica gel sealing structure of different shape and structure, it is sometimes desirable to change to the shape of the rubber seal 10
Become, so that it has more broad applicability.For example, when silica gel sealing structure is hollow structure, and need to lead in the hollow structure
When crossing water flow or air-flow, in order to improve its waterproof or anti-dust performance, then the silica gel sealing ring of above-mentioned hollow structure can be used
10.The utility model includes but is not limited to above structure, need to only meet and make up magnitude of interference by groove 11.
Specifically, please referring to Fig. 1, there is convex ribs 21, the convex ribs 21 and the silica gel sealing ring 10 on the lid 20
It is oppositely arranged, the convex ribs 21 are connected to close to compress the silica gel on the silica gel sealing ring 10 when the lid 20 pushes
Seal 10.By the way that convex ribs 21 are arranged on lid 20, when lid 20 and shell are interference fitted, it is close that convex ribs 21 are connected to the silica gel
In seal 10, to avoid the silica gel sealing ring 10 from being subjected to displacement, to improve Product Precision.
Specifically, please referring to Fig. 1, the width of the arcuate recess is less than the width of the installation cavity 30.In order to prevent should
For silica gel sealing ring 10 after being squeezed, the magnitude of interference of compensation is excessive, damages, is needed to groove to installation cavity 30
11 width is defined, and designs different size of silica gel sealing ring 10 according to different parameter requests.
Specifically, please referring to Fig. 1, the height of the arcuate recess is less than the depth of the installation cavity 30.In order to prevent should
For silica gel sealing ring 10 after being squeezed, which overflows installation cavity 30, damages, needs to installation cavity 30
The height of groove 11 is defined, different size of silica gel sealing ring 10 is designed according to different parameter requests.
Further, Fig. 1 is please referred to, there is fastener 50 on the shell, the fastener 50 is set to described
On the side wall of installation cavity 30, the fastener 50 is abutted with the silica gel sealing ring 10 to fasten the silica gel sealing ring 10.?
