Abstract

The utility model relates to a safety tank lid which includes a retaining ring, an outer cap, the retaining ring provided with a joint division, the outer cap provided with a laid-in division contacting and fixed to the joint division, a rib shaped on the lateral side of the laid-in division, a groove matching with the rib shaped on the joint division. The rib is in parallel with the covering of the outer cap. The laid-in division provided with a plurality of ribs which are on the same surface level. The rib and groove matching with each other are shaped on the outer cap and the retaining ring, the bonding force between the outer cap and the retaining ring added through mutual retaining of the rib and the groove, so as to prevent the outer cap from opening because of shaking during transportation of the canned products.

Description

Safe cover

Technical field:

The utility model relates to the cover technical field, particularly safe cover.

Background technology:

In iron jar of common product, the cover on a lot of tank bodies is to snap together by the snap ring on inlay card mode and the tank body.A lot of canned products have just had certain high temperature and have kept certain gas when encapsulating, add the sealed attachment of cover and snap ring and only pass through both persons' friction, so, in the transportation of these canned products, in case transportation means (as automobile, steamer) rocks, tank body will rock with transportation means, thereby the generation of gas in the tank body is expanded, in the time of serious, the air pressure in the tank body is enough to cover is gone out, and causes the material in the tank body to flow out.

The utility model content:

The purpose of this utility model is to provide at the deficiencies in the prior art effectively to prevent the safe cover blown automatically in transportation.

For achieving the above object, the utility model adopts following technical scheme: it comprises snap ring, enclosing cover, has sticking part on the snap ring, covers outward to have to contact fixing inlay card portion with sticking part, inlay card portion side forms fin, forms the groove that cooperates with fin on the sticking part.

Described fin is parallel to the capping of enclosing cover.

In the described inlay card portion many fins are arranged, and each fin is positioned on the same horizontal surface.

The utility model forms fin and the groove that cooperatively interacts on enclosing cover and snap ring, mutual screens by fin and groove, increase the power that is connected between enclosing cover and the snap ring, thereby guarantee that canned products, can be because of not rocking the situation that enclosing cover is washed open that produces in transportation.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the structural representation of enclosing cover of the present utility model;

Fig. 2 is the lateral plan of enclosing cover of the present utility model;

Fig. 3 is the structural representation of snap ring of the present utility model;

Fig. 4 is a scheme of installation of the present utility model.

The specific embodiment:

See accompanying drawing 1-4, the utility model comprises: snap ring 10, enclosing cover 12, snap ring 10 directly are fixed on the tank body, and enclosing cover 12 matches with snap ring 10.

Have sticking part 14 on the snap ring 10, have on the enclosing cover 12 and contact fixing inlay card portion 16 with sticking part 14, inlay card portion 16 sides form fin 18, form the groove 20 that cooperates with fin 18 on the sticking part 14.When being buckled in enclosing cover 12 on the snap ring 10, fin 18 engages mutually with groove 20, thereby makes enclosing cover 12 be connected tightr with snap ring 10.

The sticking part 14 of the utility model snap ring 10 is the U type; Inlay card of the present utility model portion 16 also is the U type; Whole inlay card portion 16 is buckled in the U type sticking part 14; Fin 18 takes shape on the lateral surface of U type inlay card portion 16, and groove 20 is opened on the lateral surface of U type sticking part 14.

Accordingly, as moulding fin 18 on the medial surface of U type inlay card portion 16, then need on the medial surface of U type sticking part 14, to offer groove 20.

Described fin 18 is parallel to the capping 22 of enclosing cover 12.

Fin 18 can be continuous being looped around in the inlay card portion 16; Also can have many, and each fin 18 is positioned on the same horizontal surface, in the time of so also guaranteeing to buckle enclosing cover 12, fin 18 and groove 20 screens.

Fin 18 also can replace with salient point.

Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, be not to limit the utility model practical range, so all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
