Description

Technical Field

[0001] This utility model relates to the field of zinc powder storage, and in particular to a moisture-proof container for zinc powder. Background Technology

[0002] Zinc powder is a fine granular metal powder made from pure zinc (Zn). It is usually light gray or silvery white and has unique physical and chemical properties.

[0003] In humid air, zinc powder adsorbs water vapor, oxygen, and carbon dioxide from the surrounding air, causing oxygen corrosion on the zinc surface through a micro-battery effect. This process eventually forms a thin film of alkaline zinc carbonate on the zinc surface. Although this film can isolate the zinc from air to some extent and protect the inner zinc layer from further oxidation, the consumption of zinc powder and changes in its properties during the reaction process can still affect its performance.

[0004] Currently, to ensure that zinc powder is not easily affected by moisture during storage, a sealing ring is often installed on the edge of the lid of the storage container. However, in actual use, due to the long-term pressure on the sealing ring, its outer wall often rubs against the edge of the container when the lid is opened and closed, which can easily cause the sealing ring to be damaged due to friction. Therefore, after long-term use, the sealing ring is prone to deformation, thus affecting the moisture-proof effect. To address this issue, a moisture-proof container for zinc powder is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a zinc powder moisture-proof container, which aims to improve the problem that the sealing ring is prone to deformation in the prior art, thus affecting the moisture-proof effect.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a zinc powder moisture-proof container, including a tank body, a tank cover is provided on the top of the tank body, the tank body and the tank cover are connected by a connecting component, a sealing mechanism is provided inside the tank cover and inside the tank body, and a shielding component is provided outside the tank body; The sealing mechanism includes a pressure chamber located on the inner wall of the can lid. A movable chamber is located on the inner wall of the can lid outside the pressure chamber. A pressing block is connected to the inner wall of the movable chamber via a piston. The end of the pressing block near the can lid is elastically connected to the inner wall of the movable chamber via a spring. The interior of the pressure chamber communicates with the interior of the movable chamber. An air bladder is fixedly connected to the outer wall of the can lid. The interior of the air bladder communicates with the interior of the pressure chamber. A waterproof groove is located on the inner wall of the can body near the top.

[0007] As a further description of the above technical solution: The connecting assembly includes a mounting block, the outer wall of which is fixedly connected to the outer wall of the tank, a sliding block slidably connected to the inner wall of the mounting block, a rotating block rotatably connected to one end of the sliding block near the tank, and the outer wall of the rotating block being fixedly connected to the outer arc surface of the tank lid.

[0008] As a further description of the above technical solution: The number of pressing blocks is set to multiple, and the multiple pressing blocks are arranged in a circular array with respect to the axis of the can.

[0009] As a further description of the above technical solution: The lower end of the pressing block on the side away from the middle of the tank is provided with an inclined chamfer.

[0010] As a further description of the above technical solution: The shielding assembly includes a shielding plate, the inner wall of which is slidably connected to the outer wall of the tank, and a water-guiding plate is fixedly connected to the outer wall of the shielding plate.

[0011] As a further description of the above technical solution: The top edge of the can lid is provided with a protrusion with a rectangular cross-section, and the thickness of the shielding plate is the same as the width of the protrusion.

[0012] As a further description of the above technical solution: The can lid is shaped like two cylinders, and the diameter of the cylindrical area below the can lid matches the inner diameter of the can.

[0013] As a further description of the above technical solution: The outer wall of the can lid has an annular groove with a semi-circular cross-section, and the outer wall of the airbag is fixedly connected to the inner wall of the groove.

[0014] This utility model has the following beneficial effects: 1. In this utility model, by setting up an air pressure chamber, a movable chamber, a pressing block, a spring, an air bladder, and a waterproof groove, the gap between the can body and the can lid can be sealed well. When opening and closing the can lid, the air bladder can be contracted, thereby avoiding friction between the air bladder and the can body. This achieves the effect of ensuring airtightness while preventing damage to the sealing components during use, thus ensuring the storage effect of zinc powder. 2. In this utility model, by setting up the shielding plate and the water guide plate, the gap at the connection between the tank body and the tank cover can be blocked, thereby ensuring that when water falls on the top of the tank body, the water body can more easily move away from the tank body along the inclined surface of the water guide plate, thereby preventing water body from entering the connection area between the tank body and the tank cover, thus preventing water body from entering the tank body and affecting the effect of zinc powder.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figure 1 , Figure 2 and Figure 4 The present invention provides an embodiment of a zinc powder moisture-proof container, comprising a tank 1 for storing zinc powder, a lid 2 provided on the top of the tank 1 for covering the opening at the top of the tank 1, the lid 2 being shaped as two cylinders, and the diameter of the cylindrical area below the lid 2 matching the inner diameter of the tank 1, the bottom cylinder of the lid 2 being located inside the tank 1, and the top cylinder of the lid 2 being located above the tank 1.

[0018] Reference Figure 1 , Figure 4 and Figure 5The can body 1 and the can lid 2 are connected by a connecting assembly 3. The connecting assembly 3 includes a mounting block 31. The outer wall of the mounting block 31 is fixedly connected to the outer wall of the can body 1. A sliding block 32 is slidably connected to the inner wall of the mounting block 31. A groove is provided on the inner wall of the mounting block 31 for the sliding block 32 to slide up and down. A rotating block 33 is rotatably connected to one end of the sliding block 32 near the can body 1. The rotating block 33 can rotate relative to the sliding block 32. The outer wall of the rotating block 33 is fixedly connected to the outer arc surface of the can lid 2. Through this connection method, it is ensured that the can lid 2 can rotate relative to the sliding block 32, thereby ensuring that the can lid 2 and the can body 1 do not need to be separated when storing or taking out zinc powder, thus preventing the can lid 2 from being lost.

[0019] Reference Figures 1-3 The can lid 2 and the can body 1 are both equipped with a sealing mechanism 4. The sealing mechanism 4 includes a pressure chamber 41, which is located on the inner wall of the can lid 2. A movable chamber 42 is located on the inner wall of the can lid 2 outside the pressure chamber 41. The movable chamber 42 is rectangular in shape. A pressing block 43 is piston-connected to the inner wall of the movable chamber 42. The outer wall of the pressing block 43 is in contact with the inner wall of the movable chamber 42. Multiple pressing blocks 43 are arranged in a circular array around the axis of the can body 1. The lower end of the side of the pressing block 43 away from the middle of the can body 1 is provided with an inclined chamfer. The inclined chamfer ensures that the inclined surface of the pressing block 43 can move towards the movable chamber 42 after being subjected to force. The end of the pressing block 43 near the can lid 2 is elastically connected to the inner wall of the movable chamber 42 by a spring 44. One end of the spring 44 is fixedly connected to the end of the pressing block 43 near the can lid 2. The other end of the spring 44 is fixedly connected to the inner wall of the movable chamber 42. The interior of the air pressure chamber 41 is connected to the interior of the movable chamber 42. An airbag 45 is fixedly connected to the outer wall of the can lid 2. The airbag 45 is annular in shape, and there are multiple airbags 45. The airbag 45 and the inner wall of the can lid 2 are integrally formed, that is, the airbag 45 does not have any holes communicating with the outside. The outer wall of the can lid 2 has an annular groove with a semi-circular cross-section. The outer wall of the airbag 45 is fixedly connected to the inner wall of the groove. The interior of the airbag 45 is connected to the interior of the air pressure chamber 41. A waterproof groove 46 is provided on the inner wall of the can body 1 near the top. The waterproof groove 46 is annular with multiple semi-circular cross-sections. This shape ensures that when the airbag 45 inflates, water needs to pass through multiple arc-shaped areas to enter the can body 1, thereby increasing the difficulty for water to enter the can body 1 and achieving a better moisture-proof effect. Reference Figures 2-4The tank body 1 is provided with a shielding component 5. The shielding component 5 includes a shielding plate 51. The height of the shielding plate 51 is higher than the height of the tank lid 2. The top edge of the tank lid 2 is provided with a rectangular protrusion. The protrusion ensures that the shielding plate 51 will not exceed the range of the tank lid 2 when it moves upward. The thickness of the shielding plate 51 is the same as the width of the protrusion. The inner wall of the shielding plate 51 is slidably connected to the outer wall of the tank body 1. The sliding direction is up and down. A water guide plate 52 is fixedly connected to the outer wall of the shielding plate 51. The water guide plate 52 is arc-shaped and the cross-section of the water guide plate 52 is inclined. The height of the end of the water guide plate 52 near the shielding plate 51 is higher than the height of the side away from the shielding plate 51.

[0020] Working principle: When using the product, after filling with zinc powder and needing to be sealed, the operator first rotates the can lid 2 to a horizontal position, and then moves the can lid 2 downward so that the cylindrical area at the bottom of the can lid 2 enters the interior of the can body 1.

[0021] Subsequently, while manually pressing the can lid 2, the staff pushed the shield 51 upward, so that the shield 51 contacted the bottom slope of the pressing block 43 as it moved upward.

[0022] When the shielding plate 51 contacts the inclined surface of the pressing block 43, the shielding plate 51 pushes the pressing block 43 in the direction of entering the moving chamber 42.

[0023] Since the air chamber 41 is connected to the moving chamber 42, during this process, the gas inside the moving chamber 42 enters the air chamber 41, thereby increasing the gas inside the air chamber 41 and increasing the pressure inside the air chamber 41. This causes the gas inside the air chamber 41 to enter the airbag 45, which inflates and fills the area inside the waterproof groove 46.

[0024] Therefore, at this time, the airbag 45 fills the area between the tank body 1 and the tank cover 2, ensuring the airtightness of the area where the zinc powder is located.

[0025] Meanwhile, because the location of the waterproof groove 46 consists of multiple arc-shaped grooves, water needs to change its original direction of movement multiple times before entering, making it difficult for water to enter the area where the zinc powder is located.

[0026] Meanwhile, because the shielding plate 51 blocks the pressing block 43, it also blocks the gap between the side of the tank body 1 and the lid 2. And because the cross-section of the water guide plate 52 is inclined, when the water falls above the tank body 1, it is easier for it to move downward slowly away from the tank body 1 along the inclined surface of the water guide plate 52, and it is not easy for it to enter the gap between the tank body 1 and the lid 2.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
