Preferably, the shrinkage pool for avoiding reduced diameter section is arranged in altar caping endface.

The utility model has the beneficial effects that:

1), the utility model is different from the inherent structure that tradition only carrys out sealing container oral area by Anti-theft cover, then separately wards off footpath Triple lids using altar lid, inner cover and outer cover of diameter design, by using altar lid as the sealing for directly cooperating altar It covers come sealing ring of arranging in pairs or groups, thus while realizing the primary seals effect of altar, then the fixation by inner cover as opposite altar Lid, and with elastic bayonet lock outer cover play positioning inner cover function so that inner cover either from radially or from By reliable location, the final relieved package effect realized to any vessel oral area in axial direction.

Specifically, altar lid is held at altar first when actual assembled, thus by flat between altar lid and altar Face paste is closed or the modes such as sealing ring sealing, carrys out optimized integration seal operation.Later, two groups of lids for constituting inner cover are radially right It closes, and ensures that face paste is closed between the inner cavity roof of inner cover and altar caping end face.After two groups of lid radial direction pairings, two groups of lids Center at notch natural involution formed pin hole, at this time by the reduced diameter section of outer cover along vertical to insertion pin hole in, from And fill up pin hole.When the shaft shoulder seam allowance of reduced diameter section insertion pin hole and outer cover is matched with inner cover top surface, elastic bayonet lock meeting at this time It radially pops up and is construed as limiting outer cover rim vertical between the cavity roof of inner cover and cooperate to the seam allowance of uplink.So far, inner cover Radial action by the Tenon of the reduced diameter section of outer cover and pin hole cooperation limits, and the axial action of inner cover then by gap slot with it is interior Cooperation between flange or positioning pin and limit, while outer cover again because elastic bayonet lock there are due to be tightly secured on inner cover, most The integrative packaging function of outer cover, inner cover, altar lid and altar is realized eventually.Because of the anti-rotation cooperation between reduced diameter section and pin hole, it is necessary to Torsion outer cover is by force to twist off relatively thin reduced diameter section, and then achievees the purpose that destroy outer cover structure, can remove this Antitheft purpose also can be realized in utility model.

2), for elastic bayonet lock, in actual use, or elastic bayonet lock can be set to the pin knot radially extended Structure, and by the reduced diameter section for being designed at outer cover of compressed spring seat integral type.When pushing outer cover, elastic bayonet lock is on edge Can be pressed in reduced diameter section because compressed spring seat acts on during pin hole downlink, and elastic bayonet lock deviate from pin hole namely When marching in the cavity of inner cover, reduced diameter section can be popped up because of the elastic-restoring force of compression spring set, matched to play seam allowance Together in the purpose at the cavity roof of inner cover.The plastics that elastic bayonet lock can also be directly arranged as to having certain elastic force are convex It rises, insertion pushes by force and assemble outer cover using the characteristic of the compression elastical retraction of plastics.The utility model, which preferably uses, to incline The cantilever rod-like structure extended obliquely upward forms elastic bayonet lock, and is arranged the holding tank accommodated for elastic bayonet lock, this to work as When outer cover downlink, elastic bayonet lock can because pin hole there are due to be compacted and be contained in naturally in holding tank, to promote its installation Efficiency.And when in cavity of the elastic bayonet lock completely into inner cover, elastic bayonet lock can pop up again because of the elastic-restoring force of itself Reduced diameter section, so that the purpose that seam allowance is matched at the cavity roof of inner cover is played, so that it is guaranteed that its locating features, more at one stroke .

3), in fact, due to elastic bayonet lock be along inclined direction and it is oblique be upwardly formed, once external force by force to On pull outer cover, then elastic bayonet lock just very likely along outer cover cavity roof slide, finally there is elastic card because of external force Pin, which is dragged, equals or even drags disconnected phenomenon.In view of this, positioning edge has also been devised in the utility model.The presence of positioning edge, so that even if External force pulls up outer cover by force, so that elastic bayonet lock can be by positioning edge when elastic bayonet lock is along the cavity roof sliding of outer cover Seamed edge and block by force, so that limit elastic bayonet lock extends out movement.The movement that extends out of elastic bayonet lock is defined, and outer cover is also The anti-theft of the utility model can not be finally improved by by force along axial extraction.

If 4), twist into two parts reduced diameter section in view of forced rotating outer cover, generally require to bestow biggish external force.This is practical It is novel that necking segment is individually set again at reduced diameter section root, so that artificial increases easy stress and deformation section.Work as forced rotating When outer cover, which can generate deformation because of external force at the first time, phenomenon of rupture finally occur at this, using extremely just It is prompt.

5), the setting for the rounded corner and inner chamfer that cambered surface is bonded to each other each other is another emphasis of the utility model.It is logical It crosses and rounded corner is set in the top end face of altar lid and the combination side of periphery wall, and in the cavity roof of inner cover and the combination of cavity wall Inner chamfer is arranged in side, when two groups of lids radially pairing, and when reduced diameter section is fully inserted into pin hole to two groups of lids of positioning, this When because inner chamfer ramp structure, can be constantly along above-mentioned radial and squeeze rounded corner, so that altar lid makees vertical under Press work.The principle of above-mentioned movement can refer to lozenges structure, when two pieces of lozenges of two groups of sliding blocks each other close by face paste, one Denier is along set direction misfit two sliding block, wherein a sliding block can relatively another sliding block generation pushing and loosening operation.And altar lid Make pressing action, the script sealing surface also allowed between altar lid and altar is more bonded, sealing effect obviously can be obtained into The promotion of one step.

6) it can also be used so that it cooperates gap more aesthetically pleasing in, the lid split side of " S " shape certainly in actual use He need to only guarantee that two cell walls of notch will not parallel above-mentioned split side similar to split structure.The flaring of outer cover is along itself axis To and postpone downwards to coating altar lid, the bottom face flush of the elongated end of the bottom face and inner cover of the flaring of outer cover, purpose It is to promote the globality of its structure to cover outer cover, inner cover and altar lid.It can more arrange at the top end face of outer cover and such as decorate The technological designs such as picture, to play the function of further beautification the utility model.

Specific embodiment

For ease of understanding, here in connection with Fig. 1-3, to the specific implementation structure and workflow of the utility model make it is following into The description of one step:

It can be still radiated in actual use by taking the altar a of wine jar sealing as an example in other similar vessel port herein In packaging structure.

The specific implementation of the utility model and the structure after installation, as shown in Figs. 1-2: bottom is the altar a of altar body, altar The altar lid 10 of ceramics or similar material is covered at the position mouth a.Both sealed between altar a and altar lid 10 or with seal washer, or Person, which is contemplated that by the way of smooth bevel even frosting, seals the two, to prevent the volatilization of the liquid such as wine liquid.

Further to promote the leakproofness between altar lid 10 and altar a, in Fig. 1 and Fig. 3 structure, the utility model is used Outer cover 30 and inner cover 20 being arranged coaxially to each other and being from top to bottom set in sequence.Inner cover 20 is downward opening barrel-like structure, Inner cover 20 is formed two groups of lid 20a by subdivision when in use.When two groups of lid 20a radially double of split as shown in Figure 3 When, the split side of two groups of lid 20a forms the split gap of " S " shape.To ensure the polarization after lid 20a split, in lid The notch 20b for having straight flange as shown in Figure 3 is set at the split side of 20a, after two groups of lid 20a radial split each other, two Group notch 20b is enclosed each other and is formed the poroid pin hole of kidney-shaped.The upper coarse and lower fine of two-part as shown in Figure 1 is then presented in outer cover 30 Stepped shaft structure.The enlarged diameter section of outer cover 30 constitutes the external section that exerts a force, in order to grab application torsion.The minor diameter of outer cover 30 Section constitutes draw pin to be inserted into pin hole, will not be radially separated from each other with playing two groups of lid 20a of constraint.It is arranged on outer cover 30 Elastic bayonet lock 31, to be acted using the elastic expansion of elastic bayonet lock 31 radially, to realize that constraint as shown in Figure 1 limits function Can, finally outer cover 30 can be reliably fixed on inner cover 20 and outer cover 30 is avoided to generate upward disengaging inner cover 20 and acts.

And in structure shown in Fig. 2, elastic bayonet lock 31 is then further refined, at this time since elastic bayonet lock 31 is that edge is inclined Tilted direction and it is oblique be upwardly formed, therefore, once external force pulls outer cover 30 upwards by force, elastic bayonet lock 31 is just very likely Cavity roof along outer cover 30 slides, and finally occurs being dragged because of external force and equals or even drag disconnected phenomenon.In view of this, the utility model Positioning edge 20c has also been devised, so that even if external force pulls up outer cover 30 by force, so that cavity of the elastic bayonet lock 31 along outer cover 30 When roof slides, elastic bayonet lock 31 can be blocked by force by the seamed edge of positioning edge 20c, so that it is dynamic to limit extending out for elastic bayonet lock 31 Make.The movement that extends out of elastic bayonet lock 31 is defined, and outer cover 30 is also impossible to finally be improved by by force along axial extraction The anti-theft of the utility model.And if in view of forced rotating outer cover 30 and twist into two parts reduced diameter section, generally require to bestow larger External force.Necking segment 33 is individually arranged in the utility model again at reduced diameter section root, so that artificial increases vulnerable to power shape Become section.When forced rotating outer cover 30, which can generate deformation because of external force at the first time, finally occur at this disconnected Split phenomenon.

For altar lid 10, arrangement shrinkage pool 11 that can be as shown in Figs. 1-2, in order to enable to when assembling outer cover 30 The displacement action of reduced diameter section can avoid open altar lid 10.Shrinkage pool 11 is set at altar lid 10 and is also equipped with the function as positioning process hole Can, so that the locating shaft of machine directly can be coaxially positioned within shrinkage pool 11 when being such as ground the frosted sealing surface of altar lid 10 It is interior, to reach the ground effect of benchmark.And the section that postpones of inner cover 20 needs to extend to altar a side wall, and arranges varus Side 21 is engaged by clamping to be formed between altar a side-walls gap slot b, for ensuring that inner cover 20 can tightly be stuck in altar a and altar At lid 10.The flaring of outer cover 40 is axial along itself and postpones to coat altar lid 10 downwards, the bottom face of the flaring of outer cover 30 with The bottom face flush of the elongated end of inner cover 20, in order to cover outer cover 30, inner cover 20 and altar lid 10, promote its structure Globality.Even between outer cover 30 and outer cover 40 can and integral structure secured to one another by glue etc., to promote its assembling effect Rate and property easy to use.It can arrange the technological designs such as decoration painting, at the top end face of outer cover 30 more to play further beauty Change the function of the utility model.
