The ring structure of hand-held set
Technical field
The present invention relates to water-tight device technical field, particularly the ring structure of hand-held set.
Background technique
For the waterproof seal of electronic equipment, have multiplely, as barrier film, O type circle, liner, safety cover, waterproof jacket etc., wherein silica gel waterproof ring is most widely used.It has the good characteristics such as temperature adapts to extensively, sealing, insulating properties, dielectricity, the feature of environmental protection.The shore hardness of silica gel waterproof ring has 20 to 90 degree.The elasticity of waterproof ring also can change along with the variation of shore hardness.Off-gauge seal ring of some complexity, its size Control is still more difficult, and owing to being subject to the impact of the each side such as material own, environment, tolerance range is also larger.High for some precision, require in larger equipment, size Control also has strict demand, otherwise is difficult to guarantee the conformity of product waterproof requirement.
During the seal ring of the large and elongated flexible of installation dimension, seal ring size designs according to product seal groove, when assembling, normally fixes several uniform points, then with hand, around periphery order, is pressed in seal groove.Because rubber has elasticity, can there is growing the phenomenon of a section because finger presses is inhomogeneous, can only reinstall again.Waste human resources, affected manufacturing efficiency.
Summary of the invention
The object of the invention is to have overcome above-mentioned shortcoming of the prior art, a kind of easy for installation, good airproof performance is provided, can improves the ring structure of the hand-held set of efficiency of assembling.
For realizing above-mentioned object, the ring structure of hand-held set of the present invention by the following technical solutions:
The ring structure of this hand-held set, its main feature is, comprise fore shell and back cover, between fore shell described in silica gel strip is arranged at and described back cover, the inner space that described fore shell and described back cover form separates by described silica gel strip and the external world, described silica gel strip is strip, and one end of this silica gel strip is fixedly connected with by silica gel glue with the other end, and described silica gel strip forms the annular of sealing by silica gel glue.
The cross section of the silica gel strip in the ring structure of this hand-held set is circular, and circle other shape installation efficiency of comparing is higher, also can do according to specific waterproof requirement other shape.
The edge of the fore shell in the ring structure of this hand-held set is provided with annular groove, and described silica gel strip is embedded in this groove, and described annular depth of groove is greater than the diameter of silica gel strip, to guarantee that silica gel strip is difficult for departing from inside grooves.
Silica gel strip in the ring structure of this hand-held set and described groove are interference fit.
The joint at the two ends of the silica gel strip in the ring structure of this hand-held set is positioned at the bottom of hand-held set.
Adopted the ring structure of the hand-held set of this structure, adopt silica gel strip to replace seal ring, avoided seal ring that inconvenient problem is installed, during installation, silica gel strip is strip, convenient operation personnel quick mounting is embedded, after installing, the head and end of silica gel strip is fixedly connected with by silica gel glue, form the loop configuration of sealing, and because the connection part of head and end is positioned at the hand-held bottom that is difficult for water inlet, therefore the reliability that has guaranteed waterproof, can substitute traditional O-ring seal during use, but more convenient than O-ring seal while installing.This structure is applicable to the relatively large or seal ring shape of machine compared with under complicated situation, and installation efficiency is more obvious in the case.On this external cost, compared with general O-ring seal, also there is certain advantage.Need to be for machine, because size shape changeable done out seal ring miscellaneous.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the ring structure of hand-held set of the present invention.
Number in the figure is described as follows:
1 fore shell
2 back covers
3 silica gel strips
Embodiment
In order more clearly to understand technology contents of the present invention, especially exemplified by following examples, describe in detail.
Refer to Fig. 1, the ring structure of this hand-held set, its main feature is, comprise fore shell 1 and back cover 2, silica gel strip 3 is arranged between fore shell 1 and back cover 2, and the inner space that fore shell 1 and back cover 2 form separates with the external world by silica gel strip 3, and silica gel strip 3 is strip, one end of this silica gel strip 3 is fixedly connected with by silica gel glue with the other end, and silica gel strip 3 forms the annular of sealing by silica gel glue.
The edge of the fore shell 1 in the ring structure of this hand-held set is provided with annular groove, and silica gel strip 3 is embedded in this groove.This annular depth of groove is greater than the diameter of silica gel strip, to guarantee that silica gel strip is difficult for departing from inside grooves.The cross section of the silica gel strip 3 in the ring structure of this hand-held set is circular.Silica gel strip 3 in the ring structure of this hand-held set and groove are interference fit.The joint at the two ends of the silica gel strip 3 in the ring structure of this hand-held set is positioned at the bottom of hand-held set.(hand-held set is vertical direction when normal use, and in Fig. 1 is horizontal positioned)
Adopted the ring structure of the hand-held set of this structure, adopt silica gel strip to replace seal ring, avoided seal ring that inconvenient problem is installed, during installation, silica gel strip is strip, convenient operation personnel quick mounting is embedded, after installing, the head and end of silica gel strip is fixedly connected with by silica gel glue, form the loop configuration of sealing, and because the connection part of head and end is positioned at the hand-held bottom that is difficult for water inlet, therefore the reliability that has guaranteed waterproof, can substitute traditional O-ring seal during use, but more convenient than O-ring seal while installing.
This structure is applicable to the relatively large or seal ring shape of machine compared with under complicated situation, and installation efficiency is more obvious in the case.On this external cost, compared with general O-ring seal, also there is certain advantage.Need to be for machine, because size shape changeable done out seal ring miscellaneous.
In this specification, the present invention is described with reference to its specific embodiment.But, still can make various modifications and conversion obviously and not deviate from the spirit and scope of the present invention.Therefore, specification and accompanying drawing are regarded in an illustrative, rather than a restrictive.
