Description

Technical Field

[0001] This utility model relates to the field of adhesive storage technology, specifically to an anti-volatile sealing structure for adhesive raw materials used in plastic storage tanks. Background Technology

[0002] Currently, the volatility of raw materials is a key concern in the production and storage of adhesives. Volatility not only leads to raw material loss and increased production costs but also poses environmental pollution and health risks to operators. Plastic storage tanks are currently the primary storage equipment for adhesive raw materials, and their sealing performance directly affects the preservation effect. However, existing plastic storage tank sealing structures generally suffer from simple design and poor sealing performance, especially under long-term use or frequent opening and closing, easily leading to seal failure due to aging, deformation, or improper installation of the seals. Furthermore, existing sealing structures typically rely on a single sealing method, lacking multiple protective measures and failing to effectively address volatilization issues under complex operating conditions. Simultaneously, some sealing structures suffer from inconvenient installation and inaccurate positioning in actual operation, further affecting the stability of their sealing performance. Therefore, designing a plastic storage tank sealing structure that can effectively prevent the volatilization of adhesive raw materials and improve sealing reliability has become an urgent technical challenge. This utility model aims to solve the above problems through innovative sealing structure design, providing a safer and more efficient solution for the storage of adhesive raw materials. Utility Model Content

[0003] This utility model relates to an anti-volatile sealing structure for adhesive raw materials used in plastic storage tanks, aiming to solve the volatility problem caused by inadequate sealing during adhesive storage in existing technologies. The problems mainly manifest as a single sealing structure, insufficient positioning accuracy, and inconvenient operation, leading to increased loss of adhesive raw materials and enhanced environmental risks during storage. Therefore, this utility model provides an anti-volatile sealing structure for adhesive raw materials used in plastic storage tanks that combines a multi-layer sealing design with a positioning and locking mechanism.

[0004] This utility model provides a sealing structure for preventing the volatilization of adhesive raw materials in plastic storage tanks, comprising a tank body and tank opening structure, a sealing cover and its sealing structure, and a positioning and locking mechanism. The tank body is a hollow structure with an integrally formed tank opening at the top for storing adhesive raw materials. The top of the tank opening has a first sealing ring groove and a second sealing ring groove, with an arc-shaped groove and an inner groove inside. A slidably connected insert with one side inclined is connected to the inner groove, and a spring is fixedly connected between the insert and the bottom wall of the inner groove to achieve the locking function of the sealing cover. A discharge pipe is provided at the bottom of the tank body for discharging the adhesive raw materials. Furthermore, the sealing cover is installed on the tank opening, and its bottom has an integrally formed first sealing ring and a second sealing ring, respectively adapted to the first and second sealing ring grooves on the tank opening, forming a double seal. An integrally formed piston is also provided at the center of the bottom of the sealing cover, corresponding to the circular hole in the center of the tank opening, further enhancing the sealing effect. A handle is fixed to the top of the sealing cover by a countersunk screw for easy opening and closing of the sealing cover.

[0005] Specifically, the positioning and locking mechanism of this utility model is achieved through the following method: A mating block and a positioning block are symmetrically arranged on the outer circumferential surface of the sealing cover. The mating block has an insertion hole, and a positioning post is fixedly connected to the bottom of the positioning block. The positioning post matches the arc-shaped groove on the can opening, ensuring accurate positioning of the sealing cover. The insertion block is reset by the action of a spring and engages with the insertion hole on the mating block to lock the sealing cover. One side of the insertion block is inclined. When the sealing cover is pressed, the insertion block is squeezed and moves into the inner groove, compressing the spring. After the sealing cover is fully closed, the insertion block resets under the action of the spring and inserts into the insertion hole on the mating block, thus achieving the locking function. Furthermore, when it is necessary to open the sealing cover, the handle is pulled to overcome the spring force and disengage the insertion block from the insertion hole, allowing the sealing cover to be easily removed.

[0006] Furthermore, the multi-seal design of this utility model is specifically achieved through the following components: the first sealing ring and the second sealing ring are respectively embedded in the first sealing ring groove and the second sealing ring groove, forming two independent sealing barriers; the piston is inserted into the circular hole in the middle of the can opening, and fits tightly against the inner wall of the circular hole, forming a third sealing barrier. The outer diameters of the first and second sealing rings are slightly larger than the inner diameters of the first and second sealing ring grooves to ensure an interference fit between them; the outer surface of the piston is precision-machined to have a high surface finish, reducing the gap between it and the inner wall of the circular hole in the can opening. In particular, the depths of the first and second sealing ring grooves are both greater than the heights of the first and second sealing rings, so that the sealing rings can be completely enclosed after embedding, preventing outside air from entering the can body.

[0007] Furthermore, the ease of operation of this utility model is achieved through the following means: a handle is provided on the top of the sealing cover, allowing the user to apply downward pressure by gripping the handle, ensuring a tight seal between the sealing cover and the can opening; simultaneously, the handle's shape is ergonomically optimized, facilitating even force application during operation. Specifically, the handle is fixed to the top of the sealing cover with countersunk screws, the heads of which are flush with the upper surface of the sealing cover, preventing any protruding parts from affecting operation or causing safety hazards.

[0008] Furthermore, the structural stability of this utility model is achieved through the following methods: the arc-shaped groove on the can opening and the positioning post cooperate to ensure that the sealing cover maintains the correct angle and position during installation; the engagement between the insert block and the insertion hole on the mating block is automatically locked by the action of a spring, preventing the sealing cover from loosening due to external vibration or impact. In particular, the inclined surface design of the insert block allows it to automatically adjust its position during pressing, ensuring precise alignment with the insertion hole; the elastic coefficient of the spring is precisely calculated to provide sufficient locking force without increasing the difficulty of operation due to excessive elasticity.

[0009] The technical effects of this utility model are manifested in the following ways: S1, the multi-seal design forms three independent sealing barriers through the combination of the first sealing ring, the second sealing ring, and the piston, effectively preventing external air from contacting the adhesive raw materials, thereby significantly reducing volatility; S2, precise positioning and reliable locking are achieved through the cooperation of the positioning pin and the arc groove to achieve accurate positioning of the sealing cover, while the linkage between the insert block and the spring achieves a reliable locking function, ensuring that the sealing structure remains stable during long-term use; S3, ease of operation is achieved through the design of the handle and the reasonable configuration of the spring, allowing users to easily open and close the sealing cover; S4, structural stability is achieved through the close cooperation between the various components, ensuring that the overall structure can maintain good sealing performance even in complex environments.

[0010] In particular, the overall structure of this utility model is compact, with clear connections and reasonable interactions between the components. The tank body and the tank opening are integrally molded, avoiding stress concentration caused by welding or splicing; the sealing cover plate and the tank opening have high fitting precision, ensuring a sealing effect while reducing assembly difficulty; the spring is made of corrosion-resistant stainless steel, extending its service life. Furthermore, all components of this utility model can be manufactured through standardized production processes, reducing production costs while improving the maintainability and replaceability of the product.

[0011] In summary, this invention solves the volatility problem of adhesive raw materials during storage by combining a multi-layer sealing design, a positioning and locking mechanism, and a convenient operation method. The proposed solution not only achieves effective sealing and long-term storage of adhesive raw materials but also improves the user experience and the overall structural stability, demonstrating significant technical advantages and practicality.

Detailed Implementation

[0020] This utility model provides a sealing structure for preventing the volatilization of adhesive raw materials in plastic storage tanks. Its overall structure is compact and functionally defined, combined with... Figure 1 To be continued Figure 4 The structure and labels shown are described in detail below, along with its implementation process and operating principle. This sealing structure includes a tank body 1, a tank opening 8, a sealing cover plate 2, and related components. These components work together precisely to achieve multiple seals, accurate positioning, and convenient operation.

[0021] The tank body 1 has a hollow structure for storing adhesive raw materials. It has an integrally formed opening 8 at the top and a discharge pipe 100 at the bottom for discharging the stored adhesive raw materials. The top of the opening 8 has a first sealing ring groove 81 and a second sealing ring groove 82, and an arc-shaped groove 83 and an inner groove 12 inside. An insert block 9 is slidably connected in the inner groove 12. One side of the insert block 9 is inclined, and a spring 13 is fixedly connected between it and the bottom wall of the inner groove 12. The spring 13 is made of corrosion-resistant stainless steel to ensure that its performance will not degrade due to environmental factors during long-term use. The design of the insert block 9 allows it to automatically adjust its position during pressing, thereby precisely aligning with the insertion hole 41 on the mating block 4 to complete the locking function of the sealing cover 2.

[0022] A sealing cover 2 is installed on the tank opening 8. Its bottom is provided with an integrally formed first sealing ring 10 and a second sealing ring 11, which are respectively embedded in the first sealing ring groove 81 and the second sealing ring groove 82, forming two independent sealing barriers. The outer diameter of the first sealing ring 10 and the second sealing ring 11 is slightly larger than the inner diameter of the first sealing ring groove 81 and the second sealing ring groove 82, achieving a tight fit through interference fit, thereby preventing outside air from entering the tank body 1. In addition, an integrally formed piston 7 is provided at the center of the bottom of the sealing cover 2. The piston 7 is inserted into the circular hole in the middle of the tank opening 8. Its outer surface is precision-machined with a high surface finish to reduce the gap between it and the inner wall of the circular hole in the tank opening, forming a third sealing barrier. The depth of the first sealing ring groove 81 and the second sealing ring groove 82 is greater than the height of the first sealing ring 10 and the second sealing ring 11, so that the sealing rings can be completely enclosed after being embedded, preventing outside air from entering the tank body 1.

[0023] A handle 3 is fixed to the top of the sealing cover 2 by a countersunk screw. The handle 3 is ergonomically optimized to allow the user to apply force evenly during operation. The user can apply downward pressure by gripping the handle 3 to ensure a tight fit between the sealing cover 2 and the can opening 8. When the sealing cover 2 is pressed, the positioning post 6 at its bottom matches the arc-shaped groove 83 on the can opening 8, ensuring accurate positioning of the sealing cover 2. At the same time, the insert 9 is squeezed and moves into the inner groove 12, compressing the spring 13. After the sealing cover 2 is fully closed, the insert 9 returns to its original position under the action of the spring 13 and inserts into the insertion hole 41 on the mating block 4, thus completing the locking function of the sealing cover 2. When it is necessary to open the sealing cover 2, the user can easily remove the sealing cover 2 by pulling the handle 3 to overcome the elasticity of the spring 13 and disengage the insert 9 from the insertion hole 41.

[0024] Furthermore, symmetrically arranged on the outer circumference of the sealing cover 2 are mating blocks 4 and positioning blocks 5. The mating blocks 4 have insertion holes 41, and the bottom of the positioning blocks 5 is fixedly connected to positioning posts 6. The positioning posts 6 are adapted to the arc-shaped grooves 83 on the can opening 8, ensuring that the sealing cover 2 maintains the correct angle and position during installation. The inclined surface design of the insertion blocks 9 allows them to automatically adjust their position during pressing, ensuring precise alignment with the insertion holes 41. The elastic coefficient of the spring 13 is precisely calculated to provide sufficient locking force without increasing operational difficulty due to excessive elasticity.

[0025] In practical application, the user first injects the adhesive material into the can body 1 through the can opening 8, then aligns the sealing cover 2 with the can opening 8 and applies downward pressure. At this time, the cooperation between the positioning post 6 and the arc groove 83 ensures that the sealing cover 2 can be accurately positioned. At the same time, the insert block 9 is squeezed and moves into the inner groove 12, compressing the spring 13. After the sealing cover 2 is completely closed, the insert block 9 is reset under the action of the spring 13 and inserted into the insertion hole 41 on the docking block 4, completing the locking function. During this process, the first sealing ring 10 and the second sealing ring 11 are respectively embedded in the first sealing ring groove 81 and the second sealing ring groove 82, and the piston 7 is inserted into the round hole in the middle of the can opening 8, forming three independent sealing barriers, effectively preventing the outside air from contacting the adhesive material and significantly reducing volatility. When it is necessary to remove the adhesive material, the user pulls the handle 3 to overcome the elasticity of the spring 13, causing the insert block 9 to disengage from the insertion hole 41, and the sealing cover 2 can be easily removed.

[0026] The overall structure of this utility model is compact, with clear connections and reasonable interactions between the components. The tank body 1 and the tank opening 8 are integrally molded, avoiding stress concentration caused by welding or splicing. The sealing cover 2 and the tank opening 8 have high fitting precision, ensuring a good sealing effect while reducing assembly difficulty. The spring 13 is made of corrosion-resistant stainless steel, extending its service life. All components can be manufactured using standardized production processes, reducing production costs while improving the product's maintainability and replaceability.

[0027] Through the above design, this utility model achieves the functions of multi-layer sealing, precise positioning, and convenient operation. The combination of the first sealing ring 10, the second sealing ring 11, and the piston 7 forms three independent sealing barriers, effectively preventing external air from contacting the adhesive raw materials, thereby significantly reducing volatility. The cooperation between the positioning post 6 and the arc groove 83 ensures that the sealing cover 2 always maintains the correct angle and position during installation. At the same time, the linkage between the insert block 9 and the spring 13 achieves a reliable locking function, ensuring that the sealing structure remains stable during long-term use. The design of the handle 3 and the reasonable configuration of the spring 13 allow users to easily open and close the sealing cover 2. The tight cooperation between the components ensures that the overall structure maintains good sealing performance even in complex environments.

[0028] In summary, this invention solves the volatility problem of adhesive raw materials during storage by combining a multi-layer sealing design, a positioning and locking mechanism, and a convenient operation method. The technical solution not only achieves effective sealing and long-term storage of adhesive raw materials but also improves the user experience and the stability of the overall structure, demonstrating significant technical advantages and practicality.

[0029] The above are merely embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
