[0026] Please see Figure 1-3This utility model provides an embodiment of an easy-open tin can: An easy-open tin can includes a can body 1 and a can lid 2. The can body 1 includes a trapezoidal fastening block 101 and a limiting block 102. Multiple sets of trapezoidal fastening blocks 101 are evenly arranged at the top of the outer side of the can body 1. The limiting block 102 is located at the top of the trapezoidal fastening blocks 101. The can lid 2 includes a fixing block 202, a movable latch 203, a trapezoidal fastening block 204, a fixing shaft 205, and a pressure relief valve 206. Multiple sets of fixing blocks 202 are arranged at the top of the outer side of the can lid 2. The movable latch 203 is located at the bottom of the fixing block 202. The trapezoidal fastening block 204... Fixed block 204 is located at the bottom of movable latch 203, and fixed shaft 205 is located at the top inside movable latch 203. Mobility between movable latch 203 and fixed block 202 can be achieved through fixed shaft 205, which extends into the interior of fixed block 202. Pressure relief valve 206 is located at the middle of the top of can lid 2, which can regulate the air pressure inside can 1, facilitating the opening and closing of tin cans while ensuring the safety of tin can use. Multiple sets of limiting grooves 201 are evenly arranged on the inner wall of can lid 2, which serve as limiting grooves and facilitate the limiting installation between can lid 2 and can 1.

[0027] Please refer to this carefully. Figure 1 and Figure 2 The outer side of the can lid 2 is provided with a fixing ring 3. The inner wall of the fixing ring 3 is provided with multiple sets of grooves 301 evenly arranged, which can fit the fixing ring 3 onto the outer side of the can lid 2. The outer wall of the fixing ring 3 is provided with multiple sets of fixing bolts 302 evenly arranged, which can fix the fixing ring 3 and prevent it from falling off the can lid 2. The outer side of the top of the can lid 2 is provided with multiple sets of slots 303 evenly arranged. The top of the inner wall of the fixing ring 3 is provided with multiple sets of locking blocks 304 that match the slots 303 evenly arranged. The matching of the slots 303 and the locking blocks 304 improves the performance of the fixing ring 3.

[0028] Please refer to this carefully. Figure 1 and Figure 3The can lid 2 has an internal mounting groove, and a rubber sealing ring is provided at the top of the mounting groove to improve the sealing between the can lid 2 and the can body 1. The can lid 2 is detachably connected to the can body 1 through the mounting groove, allowing for disassembly and assembly. The movable latch 203 is detachably connected to the trapezoidal fastening block 101 through the trapezoidal fastening block 204, facilitating the disassembly and assembly of the movable latch 203. Both ends of the fixed shaft 205 are welded to the movable latch 203. The fixed block 202 has a rotating hole inside, and the fixed shaft 205 passes through the rotating hole. The movable latch 203 is connected to the fixed block 202 through the rotating hole. Shaft 205 is rotatably connected to fixed block 202. The fixed shaft 205 allows rotation between movable latch 203 and fixed block 202, facilitating the disassembly and assembly of can lid 2. The bottom end of pressure relief valve 206 is welded to the top of can lid 2. A pressure relief hole is provided at the position of pressure relief valve 206 on the top of can lid 2, which facilitates the adjustment of air pressure inside can body 1, making the use of tin can safer. Limiting block 102 matches limiting groove 201. Can lid 2 is detachably connected to limiting block 102 through limiting groove 201, which has a limiting effect, facilitating the positioning and installation of can lid 2.

[0029] Please refer to this carefully. Figure 1 and Figure 2 The fixing ring 3 has an internal groove, through which the fixing ring 3 is detachably connected to the can lid 2. The groove allows for the assembly and disassembly of the fixing ring 3 and the can lid 2. The locking block 304 is detachably connected to the can lid 2 through the locking groove 303. The locking block 304 and the locking groove 303 can limit the installation position of the fixing ring 3. The outer wall of the fixing ring 3 has a threaded hole that matches the fixing bolt 302. The fixing bolt 302 is threadedly connected to the fixing ring 3 through the threaded hole, which serves as a limit adjustment. The thread between the fixing bolt 302 and the fixing ring 3 can be adjusted, and the position of the fixing ring 3 can be positioned, facilitating the quick opening and closing of the tin can.

[0030] Working Principle: During sealing, this invention uses the interlocking of the limiting block 102 and the limiting groove 201 to position the can lid 2 and the can body 1. The rotating hole and rotating shaft allow the movable latch 203 to rotate relative to the fixed block 202. The trapezoidal fastening block one 101 and trapezoidal fastening block two 204 come into contact, and the locking ring 3 is fitted onto the outside of the can lid 2 via the slot. The groove 301 compresses the movable latch 203, causing the trapezoidal fastening block one 101 and trapezoidal fastening block two 204 to press against each other, thereby reducing the lateral force. The pressure is converted into downward pressure on the can lid 2, thereby improving the sealing effect between the can lid 2 and the can body 1. The locking block 304 and the locking groove 303 engage with each other, thereby limiting the position of the fixed ring 3. The threaded hole allows for thread adjustment between the fixing bolt 302 and the fixed ring 3, thereby positioning the fixed ring 3 and improving the sealing effect of the tin can. The can lid 2 can be removed simply by removing the fixed ring 3. The pressure relief valve 206 can be used to adjust the pressure inside the can body 1, keeping the pressure inside the can body 1 the same as the external pressure, making the use of the tin can safer.

[0031] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.
