Abstract
The utility model provides a kind of simple and easy expansion-head, and described expansion-head comprises: inflatable body; The centre of inflatable body is open circles; Inflatable body comprises: annular portion and inflation inlet; Annular portion internal diameter is standard circular, and the outside face of annular portion is wavy shaped configuration.The technical scheme that the utility model provides has the high advantage of laminating degree.
Description
Technical field
The utility model belongs to optical cement field, particularly relates to a kind of simple and easy expansion-head.
Background technology
OCA(is English: Optically Clear Adhesive) for the extraordinary adhesive of cementing transparent optical element (as camera lens etc.).Requirement have water white transparency, light transmission rate more than 90%, cementing strength is good, can solidify under room temperature or middle temperature, and have the features such as cure shrinkage is little.
When existing optical cement is with little tube core (i.e. 3 writing brush cores) rolling, be difficult to control colloid by the defect easily producing modification after little tube core rolling; Little tube core is replaced with the defect easily producing modification after large tube core (i.e. 6 writing brush cores) then can solve rolling completely; But existing itemize equipment generally all cannot expand into the requirement of support 6 inches of tube cores with 3 inch spool, therefore expansion-head must be used to be socketed in 3 inch spool to reach the requirement of 6 writing brush cores, but though existing expansion-head can reach the requirement of 6 writing brush cores, the laminating tight ness rating of its optical cement and expansion-head is when rotated not high.
Summary of the invention
The object of the utility model embodiment is to provide a kind of simple and easy expansion-head, is intended to solve the not high problem of existing technical scheme laminating tight ness rating.
First aspect, provide a kind of simple and easy expansion-head, described expansion-head comprises: inflatable body; The centre of inflatable body is open circles; Inflatable body comprises: annular portion and inflation inlet; Annular portion internal diameter is standard circular, and the outside face of annular portion is wavy shaped configuration.
Optionally, the center of circle of the open circles center of circle in described annular portion and annular portion external diameter circle is all positioned on the axis of inflatable body, and the center of circle height of annular portion external diameter is higher than the center of circle of open circles.
Optionally, the center of circle height that described annular portion external diameter is round is higher than the center of circle 1-2mm of open circles.
Optionally, the jut of described wavy shaped configuration is evenly distributed on the outside face of annular portion.
In the utility model embodiment, the technical scheme that the utility model provides adopts simple and easy expansion-head, and this expansion-head is arranged to wavy shaped configuration at external diameter, and it has the high advantage of laminating tight ness rating.
Accompanying drawing explanation
The constructional drawing of the simple and easy expansion-head that Fig. 1 provides for the utility model.
The center of circle 21 of inflatable body 1, open circles 10, annular portion 11, inflation inlet 2, open circles and the center of circle 22 of external diameter.
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
The utility model detailed description of the invention provides a kind of simple and easy expansion-head, and this expansion-head as shown in Figure 1, comprising: inflatable body 1; The centre of inflatable body 1 is open circles 10; Inflatable body 1 comprises: annular portion 11 and inflation inlet 2; Annular portion 11 internal diameter is standard circular, and the outside face of annular portion 11 is wavy shaped configuration.
The outside face of annular portion 11 is wavy shaped configuration by the expansion-head that the utility model is arranged, and by facts have proved, this kind of structural rate standard circular has extraordinary stickiness.
Optionally, the center of circle of the open circles center of circle in above-mentioned annular portion and annular portion external diameter circle is all positioned on the axis of inflatable body 1, but the center of circle height of annular portion external diameter circle is higher than the center of circle of open circles.This kind of setting is because by facts have proved, if be concentric circles setting, the skew in its inflatable body center of circle only can offset at vertical direction, does not offset in the horizontal direction, offsets so be only only used in vertical direction.
Optionally, the center of circle height of annular portion external diameter circle is specifically as follows higher than the center of circle of open circles, and the center of circle height of annular portion external diameter circle is higher than the center of circle 1-2mm of open circles.Skew only within the scope of this just can be useful, exceeds this scope, then the harmony of expansion-head or bad.
Optionally, the jut 30 of above-mentioned wavy shaped configuration is evenly distributed on the outside face of annular portion.This kind arranges the effect can submitting laminating further to, has the advantage strengthening laminating effect.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
