Detailed Description

The present invention will be further described with reference to the accompanying drawings.

The tinplate press-screwing safety cover comprises an outer cover 1, an inner cover 2 and a key layer 3, wherein the inner cover 2 is movably embedded in the inner side of the outer cover 1, namely the outer cover 1 is sleeved on the outer surface of the inner cover 2, the outer cover 1 can be printed with an appearance and can also be made with a relief pattern, and the function of the inner cover 2 cannot be influenced.

The outer cover 1 comprises a side cover 11 and a top cover 12, the upper end edge of the side cover 11, the peripheral edge of the top cover 12 and the peripheral edge of the key layer 3 are mutually overlapped, curled and fixed together to form a bone buckling process, and stretching forming is not needed, so that patterns printed on the side cover are easy to control and cannot deform.

The key layer 3 is located between enclosing cover 1 and inner cup 2, and the die-casting has the protruding 31 of horseshoe form on the key layer 3, and the protruding 31 of horseshoe form is similar to the horseshoe form, and its cross sectional shape can be seen as arc and sharp enclose into, so the utility model discloses divide into arc end 311 and straight line end 312 with the protruding 31 of horseshoe form, have rounded structure between the protruding 31 arc end 311 of horseshoe form and key layer 3, make between the protruding 31 arc end 311 of horseshoe form and the key layer 3 more slick and sly, the bottom die-casting of inner cup 2 has locked groove 21, and locked groove 21 cooperatees with the protruding 31 of horseshoe form, and the protruding 31 matched with screw thread 22 of horseshoe form has been seted up to the inboard of inner cup 2, and the concrete fit relation is: when the utility model needs to be covered on the can, the outer cover 1 is held, the horseshoe-shaped bulge 31 is embedded into the locking groove 21, the outer cover 1 is rotated positively, and the linear end 312 of the horseshoe-shaped bulge 31 pushes the inner cover 2 to rotate, so that the inner cover 2 is screwed on the can through the thread 22; when needs will the utility model discloses when taking off from the jar, need push down enclosing cover 1 hard and reverse rotation, it is rotatory to promote inner cup 2 through the protruding 31 arc type end of shape of a hoof, makes inner cup 2 spin down from the jar.

Children want with the utility model discloses when taking off from the jar, generally only can direct reverse rotation enclosing cover 1, and can not press enclosing cover 1 to the jar, because round angle structure has been had between the protruding 31 arc end 311 of shape of a hoof and the key layer 3, make between the protruding 31 arc end 311 of shape of a hoof and the key layer 3 more slick and sly, thereby when reverse rotation enclosing cover 1, the direct arc end 311 from the protruding 31 of shape of a hoof of shape of locked groove 21 inner wall is gone up smoothly, and can not drive inner cup 2 and rotate, thereby reach the purpose that prevents that children from directly unscrewing, play certain safety action to children.

The middle part die-casting of key layer 3 has circular arch 32, and the middle part die-casting of inner cup 2 bottom has circular recess 23, and circular arch 32 and circular recess 23 mutually support, and when manual rotation enclosing cover 1, circular arch 32 imbeds in the circular recess 23, plays the effect of direction, and on the other hand designs locked groove 21 and circular recess 23 on inner cup 2, when including inside pad of pasting of lid 2, does benefit to the area of pasting that increases inside pad.

The fixed washer 13 that is provided with of side cap 11 lower extreme, washer 13 are close to the inboard setting of side cap 11, and the lower extreme of inner cup 2 is fixed to be provided with snap ring 24, and snap ring 24 is close to the outside setting of inner cup 2, and snap ring 24 mutually supports with the retaining ring, and the retaining ring keeps off snap ring 24 in the inboard of enclosing cover 1, makes inner cup 2 can not fall down from the opening of enclosing cover 1 lower extreme.

The material of enclosing cover 1 and inner cup 2 is the tinplate, adopts the tinplate as the material, and some plastics safety covers on the market, because the environmental change changes the change state easily, and the performance of tinplate is more stable than plastics safety cover, can be when protruding 31 of die-casting horseshoe-shaped and circular arch 32, and the profile at edge has the radian, and the profile is comparatively slick and sly, can not have sharp edge.

The utility model discloses a theory of operation does: when the utility model needs to be covered on the can, the outer cover 1 is held, the horseshoe-shaped bulge 31 is embedded into the locking groove 21, the outer cover 1 is rotated positively, and the linear end 312 of the horseshoe-shaped bulge 31 pushes the inner cover 2 to rotate, so that the inner cover 2 is rotated on the can; when the utility model needs to be taken off from the pot, the outer cover 1 needs to be pressed forcibly and rotates reversely, and the inner cover 2 is pushed to rotate through the arc-shaped end of the horseshoe-shaped bulge 31, so that the inner cover 2 is screwed off from the pot; and children want will the utility model discloses when taking off from the jar, generally only can direct reverse rotation enclosing cover 1, and can not press enclosing cover 1 to the jar, because round angle structure has been had between the protruding 31 arc end 311 of shape of a hoof and the key layer 3, make between the protruding 31 arc end 311 of shape of a hoof and the key layer 3 more slick and sly, thereby when reverse rotation enclosing cover 1, 21 inner walls of locked groove directly slide on the protruding 31 arc end 311 of shape of a hoof, and can not drive inner cup 2 and rotate, thereby reach the purpose that prevents children directly from unscrewing, play certain safety action to children.

The above is not intended to limit the technical scope of the present invention, and any modifications, equivalent changes and modifications made to the above embodiments according to the technical spirit of the present invention are all within the scope of the technical solution of the present invention.
