Description

Technical Field

[0001] The utility model relates to the field of tinplate lids, in particular to a recyclable medicinal tinplate lid. Background Art

[0002] Tinplate, also known as tin-coated iron, is the common name for electroplated tin thin steel plates, with the English abbreviation SPTE. It refers to cold-rolled low-carbon thin steel plates or steel strips coated with commercially pure tin on both sides. Tin mainly serves to prevent corrosion and rust. It combines the strength and formability of steel with the corrosion resistance, solderability, and beautiful appearance of tin in one material, and has the characteristics of corrosion resistance, non-toxicity, high strength, and good ductility.

[0003] With the development of the times and technology, the progress of technology has simultaneously promoted the technological progress of recyclable galvanized tinplate lids.

Detailed Embodiment

[0024] The present invention will be further described below in conjunction with the drawings and embodiments.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , wherein Figure 1 is the schematic structural diagram of a preferred embodiment of a recyclable medicinal tinplate lid provided by the present invention; Figure 2 is Figure 1 the front view of a recyclable medicinal tinplate lid shown; Figure 3 is Figure 1 the sectional view of the limiting sleeve in a recyclable medicinal tinplate lid shown; Figure 4 is Figure 1The front view of the stretching column in a recyclable medicinal tinplate lid is shown. A recyclable medicinal tinplate lid includes a lid body 1. A sealing gasket 2 is fixedly connected to the top of the inner cavity of the lid body 1. An anti-slip column 3 is fixedly connected to the front of the lid body 1. A limiting sleeve 4 is fixedly sleeved inside the lid body 1. A limiting block 5 is fixedly sleeved inside the limiting sleeve 4. A stretching column 6 is movably sleeved inside the limiting block 5. A spring 7 is movably sleeved outside the stretching column 6. A pressing plate 8 is fixedly connected to the bottom of the stretching column 6. An air inlet 9 is opened at the bottom of the inner cavity of the limiting sleeve 4. A sealing plate 10 is fixedly connected to the bottom of the pressing plate 8. A baffle 11 is fixedly connected to the top of the stretching column 6. A closing plate 12 is fixedly connected to the bottom of the baffle 11. A pull ring 13 is movably sleeved on the top of the baffle 11. A fixing mechanism 14 is arranged at the top of the limiting sleeve 4.

[0026] The stretching column 6 is located in the exact middle of the limiting sleeve 4, and the stretching column 6 is perpendicular to the pressing plate 8. By setting the stretching column 6, when opening the tinplate lid, pulling the stretching column 6 causes the stretching column 6 to drive the pressing plate 8 to lift, so that the pressing plate 8 is separated from the bottom of the inner cavity of the limiting sleeve 4, allowing the air flow outside the limiting sleeve 4 to enter the tank through the air inlet 9, thereby achieving the balance effect of the internal and external pressures of the tank, and thus achieving the effect of quickly unscrewing the tinplate lid, avoiding the problem that it is relatively complicated and laborious to ventilate inside the tinplate lid, and improving the convenience of opening and closing the tinplate lid.

[0027] The sealing gasket 2 is adapted to the lid body 1, and the material of the sealing gasket 2 is rubber. By setting the sealing gasket 2, when tightening and fixing the tinplate lid, the sealing gasket 2 fills the gap between the lid body 1 and the tank, thereby improving the sealing performance after the lid body 1 is tightened, that is, improving the airtightness after the tank is closed.

[0028] The number of anti-slip columns 3 is several, and several anti-slip columns 3 are evenly distributed outside the lid body 1. By setting the anti-slip columns 3, when unscrewing the lid body 1, the anti-slip columns 3 greatly increase the roughness of the surface of the lid body 1, that is, increase the friction on the surface of the lid body 1, thereby avoiding the problem of slipping when manually unscrewing the lid body 1, and bringing convenience to the screwing of the lid body 1.

[0029] The sealing plate 10 is movably sleeved inside the limiting sleeve 4, and the material of the sealing plate 10 is rubber. By setting the sealing plate 10, when closing and fixing the lid body 1, the spring 7 drives the pressing plate 8 to move downward, that is, drives the sealing plate 10 to tightly press against the bottom of the inner cavity of the limiting sleeve 4, thereby achieving the closing effect of the air inlet 9 and improving the sealing effect after the air inlet 9 is closed.

[0030] The closing plate 12 is located directly above the limiting sleeve 4, and the closing plate 12 is perpendicular to the stretching column 6. By setting the closing plate 12, when closing the limiting sleeve 4, the baffle 11 drives the closing plate 12 to tightly press against the top of the limiting sleeve 4, so that the gap between the stretching column 6 and the limiting sleeve 4 can be closed by the closing plate 12, thereby achieving the sealing effect of the limiting sleeve 4, avoiding the problem that external sundries of the limiting sleeve 4 enter the inside of the limiting sleeve 4 through the closing, resulting in difficulty in stretching the stretching column 6, and thus improving the cleanliness inside the limiting sleeve 4.

[0031] The pull ring 13 is made of stainless steel material, and the front shape of the pull ring 13 is an inverted U shape. By setting the pull ring 13, when lifting the stretching column 6, pulling the pull ring 13 enables the pull ring 13 to drive the stretching column 6 to be lifted, thus avoiding the problem that the pull ring 13 is too small in volume to be manually stretched, and further bringing convenience to the lifting of the stretching column 6, that is, bringing convenience to the manual opening of the cover body 1.

[0032] The fixing mechanism 14 includes a first magnet 141, the first magnet 141 is fixedly connected to the front of the pull ring 13, and the top of the limiting sleeve 4 is fixedly sleeved with a second magnet 142. By setting the fixing mechanism 14, when the tinplate cover is tightened and fixed, flipping the pull ring 13 enables the pull ring 13 to drive the first magnet 141 to tightly adsorb on the top of the second magnet 142, that is, driving the pull ring 13 to adsorb on the top of the limiting sleeve 4, thereby achieving the fixing effect of the pull ring 13, that is, achieving the fixing effect of the pull ring 13, and thus improving the regular beauty of the surface of the tinplate cover.

[0033] The working principle of a reusable medicinal tinplate cover provided by the present utility model is as follows:

[0034] Step 1: First, when opening the tinplate lid, pull the stretching column 6, so that the stretching column 6 drives the extrusion plate 8 to lift, so that the extrusion plate 8 is separated from the bottom of the inner cavity of the limit sleeve 4, so that the air flow outside the limit sleeve 4 can enter the inside of the tank through the air inlet 9, thereby achieving the balance effect of the internal and external air pressures in the tank, and thus achieving the effect of quickly unscrewing the tinplate lid, avoiding the problem of being more complicated and laborious when ventilating inside the tinplate lid, thereby improving the convenience of opening and closing the tinplate lid. When tightening and fixing the tinplate lid, the sealing gasket 2 fills the gap between the lid body 1 and the tank body, thereby improving the sealing performance after the lid body 1 is tightened, that is, improving the airtightness after the tank body is closed. When unscrewing the lid body 1, the anti-slip column 3 greatly improves the roughness of the surface of the lid body 1, that is, improves the friction force on the surface of the lid body 1, thereby avoiding the problem of the lid body 1 sliding when manually unscrewing, and thus bringing convenience to the screwing of the lid body 1. When closing and fixing the lid body 1, the spring 7 drives the extrusion plate 8 to move downward, that is, drives the sealing plate 10 to tightly press against the bottom of the inner cavity of the limit sleeve 4, thereby achieving the sealing effect of the air inlet 9 and improving the sealing effect after the air inlet 9 is closed;

[0035] Step 2: When closing the limit sleeve 4, the baffle 11 drives the closing plate 12 to tightly press against the top of the limit sleeve 4, so that the gap between the stretching column 6 and the limit sleeve 4 is closed by the closing plate 12, thereby achieving the sealing effect of the limit sleeve 4, avoiding the problem that foreign objects outside the limit sleeve 4 enter the inside of the limit sleeve 4 through the closing, resulting in difficulty in stretching the stretching column 6, and thus improving the cleanliness inside the limit sleeve 4. When lifting the stretching column 6, pull the pull ring 13, so that the pull ring 13 drives the stretching column 6 to lift, thereby avoiding the problem that the pull ring 13 is too small to be manually stretched, and thus bringing convenience to the lifting of the stretching column 6, that is, bringing convenience to the manual opening of the lid body 1. When the tightening and fixing of the tinplate lid is completed, turn over the pull ring 13, so that the pull ring 13 drives the first magnet 141 to tightly adsorb on the top of the second magnet 142, that is, drives the pull ring 13 to adsorb on the top of the limit sleeve 4, thereby achieving the fixing effect of the pull ring 13, that is, achieving the fixing effect of the pull ring 13, and thus improving the regular beauty of the surface of the tinplate lid.

[0036] Compared with the related technology, a recyclable medicinal tinplate lid provided by the present utility model has the following beneficial effects:

[0037] By setting the stretching column 6, when the tinplate cover is opened, the stretching column 6 is pulled so that the stretching column 6 can drive the extrusion plate 8 to rise, thereby separating the extrusion plate 8 from the bottom of the inner cavity of the limiting sleeve 4, allowing the external airflow of the limiting sleeve 4 to enter the interior of the tank body through the air inlet 9, thereby achieving a balance effect of the air pressure inside and outside the tank body, thereby achieving the effect of quickly unscrewing the tinplate cover, avoiding the problem of complex and laborious ventilation inside the tinplate cover, thereby improving the convenience of opening and closing the tinplate cover.

[0038] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
