The specific embodiment
Lift a preferred embodiment below, and carry out by reference to the accompanying drawings the clearer the utility model that intactly illustrates.
In description of the present utility model, it will be appreciated that, term " on ", orientation or the position relationship of the indication such as D score, 'fornt', 'back', " left side ", " right side ", " vertically ", " level ", " top ", " end " " interior ", " outward " be based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, rather than indicate or imply that the device of indication or element must have specific orientation, with specific orientation, construct and operation, therefore can not be interpreted as restriction of the present utility model.
As shown in Figure 2, the utility model seal cover cap comprises steel lid 1 and one vinyl cover 2.Wherein, this steel lid 1 comprises that a cylindrical housings 11 and is positioned at the curved portions 12 on the end face of cylindrical housings 11.This vinyl cover 2 comprises internal layer 21, an one outer 23 and one annular connecting portion 22, and annular connecting portion 22 is connected between the end face and outer 23 end face of internal layer 21.Meanwhile, the outer wall of this skin 23 is connected on the inwall of cylindrical housings 11, and annular connecting portion 22 is resisted against on the periphery of inwall of curved portions 12.
Please according to Fig. 2-3, understood, on the outer wall of this skin 23, offered two draw-in grooves 231, the inwall of this cylindrical housings 11 be provided with two respectively with the retaining sheet 3 of the corresponding setting of corresponding draw-in groove 231.This retaining sheet 3 vertically comes off downwards with respect to steel lid 1 for preventing this vinyl cover 2, and the top of retaining sheet 3 is resisted against on the inside face at top of draw-in groove 231.Meanwhile, two these draw-in grooves 231 arrange along the even interval of circumferencial direction of this skin 23, and two these retaining sheets 3 arrange along the even interval of circumferencial direction of this cylindrical housings 11.
In the present embodiment, adopt retaining sheet card holding structure, actv. has been eliminated the steel lid 1 reciprocal degree of freedom coming off with respect to vinyl cover 2, thereby has avoided vertically coming off downwards with respect to steel lid 1 because of the loosening vinyl cover 2 that causes of the skin 23 of vinyl cover 2 and the cooperation place of the cylindrical housings 11 of steel lid 1.Adopt two retaining sheets 3 not only to improve the stability of slip-off preventing performance and the structural strength of sealing lid of sealing lid simultaneously, also reduced the productive costs that sealing is covered simultaneously.
Preferably, the thickness of each retaining sheet 3 is all than the thin thickness 0.1mm of steel lid 1.Be conducive to like this retaining sheet 3 to be welded on the inwall of cylindrical housings 11 of steel lid 1, improved the welding quality of retaining sheet 3, reduced productive costs.
In addition, as Figure 2-3, each retaining sheet 3 includes the rake 32 that a vertical portion 31 and is positioned at these 31 tops, vertical portion.Wherein, the outside face of this vertical portion 31 is welded on the inwall of cylindrical housings 11, and the top of rake 32 is resisted against on the inside face at top of draw-in groove 231.Make like this when the loosening even vinyl cover 2 in cooperation place of the skin 23 of vinyl cover 2 and the cylindrical housings 11 of steel lid 1 vertically comes off downwards with respect to steel lid 1, this vinyl cover 2 is withstood at the top of this retaining sheet 3, has avoided this vinyl cover 2 vertically to come off with respect to steel lid 1 downwards.
In the present embodiment, the length of this retaining sheet 3 is 10mm, and width is 8mm, and thickness is 0.4mm.And the material of retaining sheet 3 is corrosion-resistant steel.The thickness of steel lid 1 is 0.5mm.In actual use procedure, because retaining sheet 3 is less, for the ease of retaining sheet 3 being welded on steel lid 1, adopt the welding manner of spot welding.
In addition, the angle between the line of centers of rake 32 and the line of centers of vertical portion 31 is 5 °-15 °.So not only guarantee the intensity of retaining sheet 3, also improved stability, the flexibility ratio of slip-off preventing performance simultaneously.In the present embodiment, the angle between the line of centers of this rake 32 and the line of centers of this vertical portion 31 is preferably 10.24 °.
The utility model also provides a kind of container that comprises seal cover cap as above, and this container comprises body and is arranged on the peristome on the end face of body.In this body, be formed with a cavity, in this peristome, offer a tapped bore being connected with cavity.
Wherein, as shown in Figure 2, the internal layer 21 of this vinyl cover 2 be shaped as U-shaped, outer 23 be shaped as drum-shaped.Between the inwall of the outer wall of this internal layer 21 and this skin 23, be formed with storage tank 24, the outer wall of this internal layer 21 is provided with threaded portion 211, this internal layer 21 by this threaded portion 211 with the tapped bore of this peristome for being threaded, and this peristome is arranged in this storage tank 24, the bottom surface of this skin 23 and this cylindrical housings 11 is connected on the end face of this body.Avoided like this because the loosening vinyl cover 2 that causes of the skin 23 of vinyl cover 2 and the cooperation place of the cylindrical housings 11 of steel lid 1 vertically comes off downwards with respect to steel lid 1, thereby improved the leak tightness of this container.
In sum, the utility model has been avoided becoming flexible and causing vinyl cover to come off with respect to steel cover rim vertical direction downwards because of the cooperation place of the cylindrical housings of the skin of vinyl cover and steel lid, has improved the leak tightness of this container.
Although more than described the specific embodiment of the present utility model, it will be understood by those of skill in the art that this is only casehistory, protection domain of the present utility model is limited by appended claims.Those skilled in the art is not deviating under the prerequisite of principle of the present utility model and essence, can make various changes or modifications to these embodiments, but these changes and modification all fall into protection domain of the present utility model.
