Description

Technical Field

[0001] The utility model relates to the technical field of easy-pull covers, in particular to a pressure-resistant aluminum easy-pull cover. Background Art

[0002] The pull-off lid, also known as the easy-open lid, is a lid with a pull tab used to seal cans. It is a metal packaging product, mostly made of aluminum or tinplate. It has a variety of sizes and is suitable for iron cans, aluminum cans, composite cans, PET plastic cans and paper cans, etc.

[0003] Some existing easy-open lids often have convex deformation on the lid surface due to changes in canning pressure or environmental influences, which affects the normal sales of the product. Therefore, how to design a pressure-resistant aluminum easy-open lid has become a problem that we currently need to solve. Utility Model Content

[0012] Preferably, the locking assembly includes an insertion rod, the insertion rod is fixedly connected to the moving block, a slot is provided inside the aluminum cover, and the insertion rod is adapted to the slot.

[0013] (III) Beneficial effects

[0014] The utility model provides a pressure-resistant aluminum easy-open lid, which has the following beneficial effects:

[0015] First, when there is pressure in the tank, the pressure can push the extrusion disc to move, and the extrusion disc can push the moving block to move through the connecting rod. The moving block can push the spring to contract. After the spring is squeezed, it will generate a rebound force, which will offset the pressure inside the tank, thereby reducing the bulge and deformation of the surface of the aluminum cover caused by the pressure inside the tank.

[0016] Second, when the extrusion force is large, the moving block can drive the insertion rod to be inserted into the slot during movement, thereby locking and fixing the extrusion disc, reducing the impact of pressure on the aluminum cover. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0024] like Figure 1-3 As shown, the utility model provides a technical solution: a pressure-resistant aluminum easy-open lid, comprising a can body 1 and an aluminum cover 2 arranged on the can body 1, a spring 3 is fixedly installed on the inner side wall of the aluminum cover 2, a moving block 4 is fixedly installed on one end of the spring 3, a sliding component 5 is arranged on the top of the moving block 4, the sliding component 5 comprises a slider 51, one side of the slider 51 is fixedly connected to the moving block 4, a slide groove 52 adapted to the slider 51 is opened on the inner wall of the aluminum cover 2, the slider 51 and the slide groove 52 can limit the moving range of the moving block 4, and at the same time can make the moving block 4 move more smoothly.

[0025] Furthermore, a connecting rod 6 is hinged at the bottom of the moving block 4, and an end of the connecting rod 6 away from the moving block 4 is hinged to an extrusion disc 7. An anti-corrosion layer 10 is provided at the bottom of the extrusion disc 7. The anti-corrosion layer 10 is composed of white porcelain paint, and the thickness of the anti-corrosion layer 10 is 0.8 mm. The anti-corrosion layer 10 improves the corrosion resistance of the easy-pull cover, and the safety performance is improved.

[0026] Furthermore, a locking assembly 8 is provided on one side of the moving block 4, and the locking assembly 8 includes an insertion rod 81, which is fixedly connected to the moving block 4. A slot 82 is provided inside the aluminum cover 2, and the insertion rod 81 is adapted to the slot 82. When the extrusion disc 7 pushes the moving block 4 upward through the connecting rod 6, when the extrusion force is large, the moving block 4 can drive the insertion rod 81 to be inserted into the slot 82 during movement, thereby locking and fixing the extrusion disc 7 and reducing the influence of pressure on the aluminum cover 2.

[0027] Furthermore, a sealing rubber pad 9 is fixedly mounted on the outer surface of the extrusion disc 7, and the sealing rubber pad 9 contacts the inner wall of the aluminum cover 2, and the sealing rubber pad 9 can increase the sealing performance of the extrusion disc 7.

[0028] The working process of the utility model is as follows: when in use, once pressure appears in the tank body 1, the pressure can push the extrusion disc 7 to move, and the extrusion disc 7 can push the moving block 4 to move through the connecting rod 6. The moving block 4 can push the spring 3 to contract under the cooperation of the slider 51 and the slide groove 52. After being squeezed, the spring 3 will generate a rebound force, which will offset the pressure inside the tank body 1, thereby reducing the convex deformation of the surface of the aluminum cover 2 caused by the pressure in the tank body 1; when the extrusion force is large, the moving block 4 can drive the insertion rod 81 to be inserted into the slot 82 during movement, so that the extrusion disc 7 is locked and fixed, reducing the influence of pressure on the aluminum cover 2.
