Description

Technical Field

[0001] This utility model relates to the field of paper drum technology, specifically to a chemical paper drum that is easy to seal. Background Technology

[0002] With the booming development of the chemical industry, the safe storage and efficient transportation of chemical raw materials have become the focus of industry attention. Chemical paper drums occupy an important position in the packaging field due to their advantages of being environmentally friendly, lightweight and cost-controllable.

[0003] Chinese Patent CN218401420U discloses a corrosion-resistant and acid / alkali-resistant chemical paper drum, including a paper drum and a lid. A corrosion-resistant layer is fixedly connected to the inner wall of the paper drum, and an acid / alkali-resistant layer is fixedly connected to the surface of the corrosion-resistant layer. The corrosion-resistant layer on the inner wall of the paper drum is made of carbon fiber to protect the paper drum from corrosion, while the acid / alkali-resistant layer is made of fluorocarbon resin to protect the paper drum from acids and alkalis. The waterproof layer is made of polyurea waterproof material to effectively prevent leakage of items placed on the inner wall of the paper drum, thus preventing the paper drum from getting wet. This solves the problem of poor corrosion and acid / alkali resistance in existing paper drums. By moving the hook upwards via a pin in the fixing mechanism, and then moving the movable frame downwards in the groove via a slider when the hook is in a vertical position, the hook engages with the groove, thus fixing the paper drum to the lid. Furthermore, the engagement between the slider and the groove is very strong even without force.

[0004] The aforementioned corrosion-resistant and acid-alkali-resistant chemical paper drums rely solely on hooks to engage with slots to secure the lids. However, a gap exists between the hooks and slots, making it difficult to create a completely sealed space. This results in poor sealing performance and cumbersome operation when sealing the paper drums, making it unsuitable for packaging complex transportation environments and high-requirement materials. Utility Model Content

[0005] The purpose of this invention is to provide a chemical paper drum that is easy to seal, so as to solve the problems of poor sealing performance and cumbersome operation in the paper drum sealing methods mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A chemical paper drum that is easy to seal includes a paper chemical container. An armored ring is fixedly installed on the upper surface of the paper chemical container. An embedded ring groove is formed on the outer surface of the armored ring. A top cover is fitted onto the outer surface of the armored ring. A rubber ring is extended from the lower surface of the top cover. The rubber ring can be fitted onto the outer surface of the armored ring along with the top cover. A tightening mechanism is installed inside the rubber ring so that the tightening mechanism can tighten the rubber ring and squeeze it into the embedded ring groove.

[0008] As a further embodiment of this utility model, an embedding plate is fixedly installed on the lower surface of the top cover, and the embedding plate can be inserted into the inner ring of the paper chemical container along with the top cover.

[0009] As a preferred embodiment of this utility model, the tightening mechanism includes a connecting ring, which is fixedly installed on the upper surface of the top cover. A connecting disc is slidably installed inside the connecting ring, and a tightening rope is fixedly connected to the lower surface of the connecting disc. The other end of the tightening rope passes through the connecting tube into the rubber ring. The connecting tube is fixedly installed on the upper surface of the top cover and communicates with the connecting ring.

[0010] As a further embodiment of this utility model, a handle is rotatably mounted on the outer surface of the connecting ring, and a lifting rod is fixedly mounted on the upper surface of the connecting disc. The lifting rod is located inside the handle, so that the user can tighten the tightening rope by holding the handle on the outer surface and pulling the lifting rod with their fingers.

[0011] As a further preferred embodiment of this utility model, a guide block is fixedly installed on the outer surface of the connecting plate, and the guide block is slidably installed in the shaped guide groove, which is opened in the connecting ring.

[0012] As a further embodiment of this utility model, a rectangular spring is embedded and rotatably connected to the lower surface of the connecting plate, and the other end of the rectangular spring is fixedly connected to the upper surface of the top cover.

[0013] Compared with the prior art, the advantages of this utility model of an easy-to-seal chemical paper drum are as follows:

[0014] When sealing paper chemical containers, the top cover is placed on the outer surface of the armor ring. During the sealing process, the top cover will simultaneously move the rubber ring extending from the lower surface onto the outer surface of the armor ring. Then, the operator can grasp the outer surface of the tightening mechanism, squeeze it, and rotate it within a range of 30-90°. After squeezing the tightening mechanism, the rubber ring will tighten and be inserted into the embedded groove on the outer surface of the inner armor ring, thus sealing the paper chemical container. This "ring embedded in the groove" forms a mechanical locking seal, which, compared to traditional buckle or threaded structures, can more tightly fill the gap between the lid and the container body, effectively preventing liquid and gas leakage. The 30-90° rotation ensures that the tightened rubber ring remains in a tight state, allowing the operator to complete the process with just two steps: "putting on the top cover → squeezing and rotating the tightening mechanism," which can be done with one hand.

[0023] See Figure 1 As shown in the figure, an embodiment of the present invention provides a chemical paper drum that is easy to seal, including a paper chemical container 1. An armor ring 101 is fixedly installed on the upper surface of the paper chemical container 1. An embedded ring groove 102 is opened on the outer surface of the armor ring 101. A top cover 103 is fitted on the outer surface of the armor ring 101. A rubber ring 105 is installed on the lower surface of the top cover 103. The rubber ring 105 can be fitted onto the outer surface of the armor ring 101 along with the top cover 103. A tightening mechanism 2 is installed inside the rubber ring 105, so that the tightening mechanism 2 can tighten the rubber ring 105 and squeeze it into the embedded ring groove 102. An insert plate 104 is fixedly installed on the lower surface of the top cover 103. The insert plate 104 can be inserted into the inner ring opening of the paper chemical container 1 along with the top cover 103.

[0024] When sealing the paper chemical container 1, the top cover 103 can be placed on the outer surface of the armor ring 101. During the sealing process, the top cover 103 will simultaneously cause the rubber ring 105, which is extended from the lower surface, to fit onto the outer surface of the armor ring 101. Then, the operator can hold the outer surface of the tightening mechanism 2, squeeze it, and rotate it within a range of 30-90°. After squeezing the tightening mechanism 2, the rubber ring 105 will tighten and be inserted into the inset opening on the outer surface of the inner armor ring 101. The sealing operation of the paper chemical container 1 can be realized in the annular groove 102. This "ring embedded in the groove" design forms a mechanical locking seal. Compared with the traditional buckle or thread structure, it can fill the gap between the lid and the body of the container more tightly, effectively preventing liquid and gas leakage. The 30-90° twist can keep the tightened rubber ring 105 in a tight state at all times. The operator only needs to perform two operations: "put on the top cover 103 and squeeze the rotating tightening mechanism 2", which can be completed with one hand.

[0025] See Figure 2 , 3 As shown, the tightening mechanism 2 includes a connecting ring 201, which is fixedly installed on the upper surface of the top cover 103. A connecting disc 204 is slidably installed inside the connecting ring 201. A tightening rope 206 is fixedly connected to the lower surface of the connecting disc 204. The other end of the tightening rope 206 passes through the connecting pipe 106 and into the rubber ring 105. The connecting pipe 106 is fixedly installed on the upper surface of the top cover 103 and communicates with the connecting ring 201.

[0026] A handle 202 is rotatably mounted on the outer surface of the connecting ring 201, and a lifting rod 205 is fixedly mounted on the upper surface of the connecting disc 204. The lifting rod 205 is located inside the handle 202, so that the user can tighten the tightening rope 206 by holding the handle 202 on the outer surface and pulling the lifting rod 205 with his / her fingers.

[0027] A guide block 207 is fixedly installed on the outer surface of the connecting plate 204. The guide block 207 is slidably installed in the 7-shaped guide groove 203. The 7-shaped guide groove 203 is opened in the connecting ring 201. A rectangular spring 208 is embedded and rotatably connected to the lower surface of the connecting plate 204. The other end of the rectangular spring 208 is fixedly connected to the upper surface of the top cover 103.

[0028] During use, after placing the top cover 103 on the upper end of the paper chemical container 1 and fitting the rubber ring 105 onto the outer surface of the armor ring 101, the user can hold the handle 202 by hand and pull the lifting rod 205. The lifting rod 205 will cause the connecting plate 204 to slide upward within the connecting ring 201, overcoming the elastic force of the rectangular spring 208. The tightening rope 206, fixedly connected to the lower surface of the connecting plate 204, will be pulled accordingly. The tightening rope 206, through the connecting tube 106, pulls the tightening rope 206 inserted into the rubber ring 105, thereby achieving radial tightening of the rubber ring 105. The tight rubber ring 105 can be inserted into the embedded ring groove 102 to seal the paper chemical container 1. The insertion of the rubber ring 105 achieves a tight physical fit, effectively filling the gap between the lid and the container body, greatly reducing the risk of liquid and gas leakage. This provides reliable protection for transporting highly corrosive chemical raw materials and volatile substances with extremely high sealing requirements, ensuring material safety and environmental safety. At the same time, the elasticity of the rubber ring 105 allows it to adapt to the slight deformation of the container body caused by manufacturing tolerances, transportation bumps, etc., maintaining a good sealing effect at all times and ensuring the long-term effectiveness and stability of the seal. Furthermore, during the upward pulling of the connecting disc 204, the guide block 207 on the outer surface of the connecting disc 204 moves upward along the vertical section of the 7-shaped guide groove 203. When the guide block 207 reaches the top of the vertical section, rotating the handle 202 and the lifting rod 205 clockwise allows the lifting rod 205 to drive the guide block 207 into the horizontal section of the 7-shaped guide groove 203. At this time, the elastic force generated by the pulled rectangular spring 208 increases the damping force between the guide block 207 and the horizontal section of the 7-shaped guide groove 203, forming a self-locking state. This ensures that the tightening rope 206 remains taut, guaranteeing the rubber ring. The 105 is firmly embedded in the inner ring groove 102, achieving a highly efficient seal for the paper chemical container 1. The entire sealing process is simple and intuitive. The operator only needs to hold the handle 202 and pull up the lifting rod 205, and then rotate the handle 202 and the lifting rod 205 to complete the sealing. No complicated operating skills or additional tools are required, which reduces the training cost and labor intensity of the operators. Compared with traditional sealing methods, this design significantly reduces the time and steps required for sealing, and significantly improves the efficiency of packaging operations. It is especially suitable for large-scale production and fast delivery scenarios, which can effectively shorten the turnover time of goods and improve the logistics efficiency of enterprises.

[0029] In summary, this embodiment of the utility model only requires holding the handle 202 and pulling up the lifting rod 205 during the sealing process of the paper chemical container 1, and then rotating the handle 202 and the lifting rod 205 to complete the process. No complicated operating skills or additional tools are required, which reduces the training cost and labor intensity of operators. Compared with traditional sealing methods, it significantly reduces the time and steps required for sealing, and significantly improves the efficiency of packaging operations. It is especially suitable for large-scale production and fast delivery scenarios, and can effectively shorten the cargo turnover time and improve the logistics efficiency of enterprises.
