Description
Technical Field
The utility model relates to a rubber circle technical field, concretely relates to waterproof rubber circle.
Background
At present, in some electronic device fields, because local spare part has waterproof demand when the assembly, usually need set up the sealing washer between several spare parts, in order to reach sealed effect, for example can set up the rubber circle between the battery compartment of cell-phone and back lid and carry out waterproof, and the general way is setting up the cell body around the battery compartment, place the rubber circle in the cell body, the lid closes again behind the cell-phone, the rubber circle of this department has obvious difference with common rubber circle, firstly, the rubber circle shape of this department is irregular, usually need order according to actual equipment, secondly, the rubber circle shape of this department is big but the diameter of rubber body is little, make the rubber circle softer and easy deformation, lead to in the assembling process of cell-phone equipment, the rubber circle of this department is difficult to arrange in order and is difficult to install into the cell body.
SUMMERY OF THE UTILITY MODEL
In view of this, the utility model aims at overcoming the defect among the prior art, provide a waterproof rubber circle for electronic equipment battery compartment's is waterproof, non-deformable in the assembling process.
The utility model discloses a waterproof rubber circle has straightway and bending segment in its circumference in turn, the straightway with bending segment connects jointly and forms cyclic annular main part, cyclic annular main part includes non-deformable's elasticity covering and the cladding at the outer elastic glue layer of elasticity covering, the elasticity covering includes that the cross-section is circular shape rubber core and is the heliciform winding metal wire on the rubber core, the rubber core extend from the helical gap of metal wire connect the wing with elastic glue layer connects as an organic wholely.
Furthermore, the metal wire is only spirally wound on the rubber core body of the straight line section, and the rubber core body of the bent section and the elastic rubber layer are connected into a whole through the connecting fins.
Further, the elastic glue layer is provided with an inner cavity, the elastic core is positioned in the inner cavity, and air bags are formed on the upper side and the lower side of the elastic core.
Further, the inner cavity is oval, the elastic glue layer is provided with a circular outer diameter, and the long axis direction of the oval inner cavity is perpendicular to the plane of the annular main body.
The utility model has the advantages that: the utility model discloses a waterproof rubber circle keeps the shape through set up the elasticity package core in rubber circle, and the elasticity package core comprises the rubber core and is the metal silk of heliciform winding on the rubber core for the elasticity package core is difficult to take place to warp, adjusts and installs more easily in assembly process.

The invention will be further described with reference to the following figures and examples:
fig. 1 is a schematic view of the installation of the present invention;
FIG. 2 is an enlarged view of FIG. 1 at A;
FIG. 3 is a schematic structural view of a middle straight line segment according to the present invention;
fig. 4 is a schematic cross-sectional view of the present invention;

Description of reference numerals: the device comprises a straight line section 1, a bent section 2, an elastic glue layer 3, a rubber core 4, a metal wire 5, a connecting fin 6 and an air bag 7.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely below, and it should be apparent that the described embodiments are only some embodiments of the present invention, but not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1 to 5, a waterproof rubber ring in the present embodiment has straight sections 1 and curved sections 2 alternately in the circumferential direction, the straight line section 1 and the bending section 2 are connected together to form an annular main body, the annular main body comprises an elastic core-spun which is not easy to deform and an elastic glue layer 3 coated on the outer layer of the elastic core-spun, the elastic core-spun comprises a rubber core body 4 with a circular section and a metal wire 5 spirally wound on the rubber core body 4, the rubber core body 4 with the circular section has deformation recovery capability, the metal wire 5 wound on the rubber core body 4 can play a role in assisting resilience, so that the waterproof rubber ring integrally keeps the shape during molding, the rubber core 4 extends out of the spiral gap of the metal wire 5 to form a connecting fin 6 which is connected with the elastic rubber layer 3 into a whole, and the elastic rubber layer 3 and the rubber core 4 can be made of the same material.
Compared with the bending section 2, the straight line section 1 is easier to deform, meanwhile, the metal wire 5 spirally wound on the rubber core 4 has a straightening effect on bent rubber, if the metal wire 5 is wound outside the rubber core 4 of the bending section 2, the rubber core 4 at the position necessarily needs larger internal stress to keep bending, therefore, in the embodiment, the metal wire 5 is only spirally wound at the rubber core 4 of the straight line section 1, and the rubber core 4 and the elastic rubber layer 3 of the bending section 2 are connected into a whole through the connecting fin 6.
The waterproof rubber circle of battery compartment should the emergence of the infiltration condition usually, and when the infiltration took place, water was from outside toward interior infiltration, can not have higher water pressure, should the infiltration, and the most effective mode is that increase the area of contact between rubber circle and back lid or the cell body, but traditional waterproof rubber circle of battery compartment's cross-section is circular usually, and area of contact is little, in this embodiment, elastic glue layer 3 has the inner chamber, the elasticity package core is located in the inner chamber to form gasbag 7 in the upper and lower side of elasticity package core, after the back lid combination, elastic glue layer 3 takes place great deformation for area of contact increase prevents the further emergence of infiltration.
In this embodiment, the inner chamber is oval, just elastic rubber layer 3 has circular shape external diameter, the major axis direction of oval inner chamber with the plane at cyclic annular main part place is perpendicular, and elastic rubber layer 3 is when taking place deformation, and the deformation that the major axis direction of oval inner chamber takes place is great, and the deformation that the minor axis direction takes place is less.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
