Description

Inner and outer cover fixing structure

Technical Field

The utility model relates to a bowl cover technical field especially relates to an inside and outside lid fixed knot constructs.

Background

The caps on the market at present are mostly composed of an inner cap and an outer cap, wherein the inner cap is generally made of plastic, and the outer cap is made of stainless steel. Therefore, in winter, the deformation degree of the inner cap is greater than that of the outer cap, which may cause a gap between the inner cap and the outer cap and a slip, thereby affecting the opening operation of a user, and more seriously causing the inner cap and the outer cap to be separated from each other.

Disclosure of Invention

The utility model discloses produce the defect that the clearance leads to skidding and even the two breaks away from because of the ambient temperature changes between inner cup and the enclosing cover to exist among the prior art, provide a new inside and outside lid fixed knot and construct.

In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

the utility model provides an inside and outside lid fixed knot constructs, includes enclosing cover, inner cup, still includes the intermediate junction piece, the enclosing cover with the intermediate junction piece is connected through gluing the adhesive and the enclosing cover will including the inner cup cladding, the enclosing cover with the material of intermediate junction piece is the same, be provided with fixed recess on the intermediate junction piece, fixed recess bottom is perforated, be provided with fixed projection in the inner cup, big-end-up of fixed projection, big-end-up of fixed recess, fixed projection with fixed recess block.

Inner cup and intermediate junction piece are connected with the help of the cooperation of fixed projection and fixed recess, the great and lower extreme diameter of fixed projection upper end diameter is less, and the internal diameter from the top down of fixed recess diminishes gradually, this kind of design can be better with intermediate junction piece and inner cup zonulae occludens together, and simultaneously, because the enclosing cover is the same with the material of intermediate junction piece, and it is inseparabler to bond between the same kind of material, consequently setting up of intermediate junction piece has consolidated being connected between inner cup and the enclosing cover, make the connection of the two inseparabler.

Preferably, in the inner and outer cover fixing structure, there are 4 fixing grooves, and the fixing grooves are arranged on the intermediate connecting piece in an annular array.

The number of the fixed grooves and the number of the fixed convex columns are four respectively, and the fixed grooves and the fixed convex columns are arranged in an annular array mode, so that the connection between the middle connecting sheet and the inner cover can be better reinforced.

Preferably, in the fixing structure for the inner cover and the outer cover, the inner cover is provided with a connecting sheet accommodating groove, and the middle connecting sheet is arranged in the connecting sheet accommodating groove.

The connecting sheet placing groove is arranged to further reinforce the connection between the middle connecting sheet and the inner cover, so that the middle connecting sheet is not easy to slide transversely on the inner cover.

Preferably, in the above inner and outer cover fixing structure, the inner cover is provided with an adhesive overflow groove.

The glue overflowing groove reduces the technological requirement for adhering the middle connecting sheet and the outer cover, and the excessive adhesive can be contained in the glue overflowing groove in the assembling process, so that the excessive adhesive cannot flow out of the connecting part of the inner cover and the outer cover.

Preferably, the inner cover and the outer cover are fixed, an annular clamping groove is formed in the outer wall of the inner cover, an annular clamping portion is formed in the outer cover, and the annular clamping portion is matched with the annular clamping groove.

The setting in annular joint portion and annular joint groove can be so that be connected between inner cup and the enclosing cover inseparabler, and liquid is difficult for getting into between inner cup and the enclosing cover to the connection structure between inner cup and the enclosing cover construct into the corruption in the use.

Preferably, the inner and outer cover fixing structure further comprises an inner core, an inner steel core and a silica gel ring, the inner core is fixedly connected with the inner cover, the inner steel core is clamped with the inner core, the silica gel ring is fixed on the inner core, and the silica gel ring abuts against the outer surface of the inner steel core.

The arrangement of the inner steel core and the silica gel ring ensures that liquid in the cup can not contact the inner core and the inner cover, so that the material requirements of the inner core and the inner cover are reduced, and the cost is reduced.
