Description

Technical Field

[0001] This utility model relates to the field of lunch box technology, and more specifically, to a double-layer waterproof and oil-resistant lunch box. Background Technology

[0002] With today's fast-paced lifestyle, people often bring their own meals to school, work, or travel. Compared to disposable lunch boxes, these are safer and more hygienic, and more environmentally friendly as they can be reused multiple times. They are usually divided into two layers to hold different foods, making them convenient for people to use multiple times.

[0003] Chinese patent application number CN202320838966.7 discloses a double-layer lunch box, specifically relating to the field of tableware technology. The box includes a box body comprising a stainless steel inner layer and a plastic outer layer. Folded portions are provided around the perimeter of the stainless steel inner layer facing the plastic outer layer. Insertion portions are provided on the plastic outer layer corresponding to the folded portions. The insertion portions are at least partially disposed inside the plastic outer layer. The folded portions cooperate with the insertion portions to insert the perimeter of the stainless steel inner layer into the plastic outer layer.

[0004] The above technical solution involves setting a folding part on the stainless steel inner layer and an insertion part on the plastic outer layer. The insertion part is at least partially located inside the plastic outer layer. The stainless steel inner layer can be inserted into the insertion part on the plastic outer layer through the folding part. This prevents water from entering the interior of the lunch box through the gap between the stainless steel inner layer and the plastic outer layer during high-temperature cleaning and disinfection, thus ensuring that the lunch box has good waterproof function and meets hygiene standards. However, the above tableware requires a certain amount of time to assemble and disassemble, which is cumbersome. In addition, the amount of food that can be placed is limited, which limits its use. Utility Model Content

[0005] The purpose of this invention is to provide a double-layered, waterproof, and oil-resistant lunch box to solve the problems mentioned in the background art. To achieve the above objectives, this utility model provides the following technical solution: A double-layered, waterproof, oil-resistant lunch box includes a lunch box body, which is divided into an upper box body and a lower box body. An adjustment groove is provided in the lower box body. A first upright is fixed in the adjustment groove. A collar is fixed on the first upright and a spring is fixed on the collar. A recessed groove is provided on the bottom surface of the adjustment groove. A sliding locking assembly is slidably connected in the recessed groove. The other end of the spring is fixed to the sliding locking assembly.

[0006] By adopting the above technical solution, when subjected to external thrust, the spring will extend accordingly, and when there is no external thrust, the spring will generate restoring elasticity to drive the push-and-lock assembly to quickly return to its original position.

[0007] Preferably, the push-and-lock assembly includes a base plate, an L-shaped block fixed on the top surface of the base plate, a triangular block fixed on the side wall of the L-shaped block, a locking block fixed on the top surface of the base plate, and a blocking block fixed on the top surface of the base plate. The side wall of the blocking block contacts the inner side wall of the adjustment groove.

[0008] By adopting the above technical solution, the triangular block has a curved surface on the approach side and an inclined surface on the return side. The card block has a groove structure. The inclined surface on the approach side is longer and steeper, while the inclined surface on the return side is shorter and gentler. This allows for a longer buffer section when the L-shaped rod enters, and the friction of the inclined surface reduces the thrust. When splitting, a smaller force is needed to separate the two parts.

[0009] Preferably, a second upright is fixed to the top surface of the base plate, a fixing block is fixed to the body of the second upright, the end of the spring is fixed to the end face of the fixing block, and the blocking block, the locking block, and the triangular block form an inlet and a outlet.

[0010] Preferably, the end of the adjusting groove is provided with a semi-circular groove, the inside of the semi-circular groove is provided with a ball groove, a ball is provided in the ball groove, and an L-shaped rod is fixedly connected to the ball, the L-shaped rod extending to the starting point of the inlet and outlet.

[0011] By adopting the above technical solution, the diameter of the sphere is slightly smaller than the diameter of the sphere groove, and the sphere can roll within the sphere groove to adjust the position of the L-shaped rod, so that it can be inserted into the locking block through the inlet or returned to the origin through the loop.

[0012] Preferably, the adjusting groove has a through groove, which communicates with the slot on the top surface of the lower box. The bottom surface of the through groove has a sliding groove, and the bottom surface of the L-shaped block has a slider that is slidably connected to the sliding groove. The L-shaped block inside the slot has an irregularly shaped piece fixed on it.

[0013] By adopting the above technical solution, the cooperation between the slide and the slider can prevent hard friction between the L-shaped block and the through groove, making the pushing process smoother.

[0014] Preferably, the bottom surface of the upper box is fixed with an insert block, the end of the insert block fits into the irregularly shaped piece, and when the L-shaped rod is inserted into the insert block, there is a gap between the end of the insert block and the slot.

[0015] By adopting the above technical solution, since the upper box needs to be pushed continuously during disassembly, a gap needs to be left between the insert block and the slot for adjustment.

[0016] Preferably, the top surface of the upper box body is provided with a sealing groove, a box lid is inserted into the sealing groove, and a carrying rod is provided on the lunch box body.

[0017] By adopting the above technical solution, the sealing groove is used to prevent internal heat from escaping after the lid is closed, thus achieving the effect of heat preservation, and the handle makes it easy to move the lunch box body.

[0018] Compared with the prior art, the beneficial effects of this utility model are: 1) When assembling the upper and lower boxes, insert the insert block on the bottom of the upper box into the corresponding slot. When the insert block contacts the irregularly shaped block, it will generate a pushing force on the L-shaped block. The spring will be stretched under the force, and the bottom plate will move synchronously in the direction of the pushing force, that is, towards the semi-circular groove. The ball rolls in the ball groove, driving the L-shaped rod through the path to the position of the locking block to complete the locking.

[0019] 2) When disassembly is required, continue to apply the pushing force in the direction of the semi-circular groove. The insert pushes the L-shaped block to move towards the end of the slot. When the insert reaches the end of the slot, the L-shaped rod disengages from the locking block and is in the loop. At this time, the pushing force is removed. Under the restoring force of the spring, the insert gradually slides out of the slot. The process is made smoother by the action of the slider, thus completing the disassembly of the upper and lower boxes. Attached Figure Description

[0022] Example 1, please refer to Figures 1 to 4A double-layered, waterproof, oil-resistant lunch box includes a lunch box body 1, which is divided into an upper box body 2 and a lower box body 3. An adjustment groove 4 is provided in the lower box body 3. A first upright rod 5 is fixed in the adjustment groove 4. A collar 6 is fixed on the first upright rod 5. A spring 7 is fixed on the collar 6. A recessed groove 8 is provided on the bottom surface of the adjustment groove 4. A push-and-lock assembly 9 is slidably connected in the recessed groove 8. The other end of the spring 7 is fixed to the push-and-lock assembly 9. When subjected to external pushing force, the spring 7 will extend accordingly. When there is no external pushing force, the spring 7 generates a restoring elastic force to drive the push-and-lock assembly 9 to quickly return to its original position.

[0023] The push-and-lock assembly 9 includes a base plate 10, an L-shaped block 11 fixed on the top surface of the base plate 10, a triangular block 12 fixed on the side wall of the L-shaped block 11, a locking block 13 fixed on the top surface of the base plate 10, and a blocking block 14 fixed on the top surface of the base plate 10. The side wall of the blocking block 14 contacts the inner side wall of the adjusting groove 4. The surface of the triangular block 12 on the inlet 17 side is curved, and the surface on the loop 18 side is inclined. The locking block 13 has a groove structure. The inclined surface on the inlet 17 side is longer and steeper, while the inclined surface on the loop 18 side is shorter and gentler. This allows for a longer buffer section when the L-shaped rod 22 enters, and the friction of the inclined surface reduces the pushing force. When disassembling, a smaller force is needed to separate the two parts.

[0024] A second upright 15 is fixed to the top surface of the base plate 10. A fixing block 16 is fixed to the body of the second upright 15. The end of the spring 7 is fixed to the end face of the fixing block 16. The blocking block 14, the locking block 13, and the triangular block 12 form the inlet 17 and the loop 18. A semi-circular groove 19 is opened at the end of the adjusting groove 4. A ball groove 20 is opened inside the semi-circular groove 19. A ball 21 is provided in the ball groove 20. An L-shaped rod 22 is fixedly connected to the ball 21. The L-shaped rod 22 extends to the starting point of the inlet 17 and the loop 18. The diameter of the ball 21 is slightly smaller than the diameter of the ball groove 20. The ball 21 can roll in the ball groove 20 to adjust the position of the L-shaped rod 22, so that it can be locked into the locking block 13 through the inlet 17, or return to the original position through the loop 18.

[0025] The steps of using this utility model are as follows: When assembling the upper box 2 and the lower box 3, insert the insert block 28 on the bottom surface of the upper box 2 into the corresponding slot 24. When the insert block 28 contacts the irregularly shaped block 27, it will generate a pushing force on the L-shaped block 11. The spring 7 will be stretched under the force, and the bottom plate 10 will move synchronously in the direction of the pushing force, that is, move towards the semi-circular groove 19. The ball 21 rolls in the ball groove 20, driving the L-shaped rod 22 through the inlet 17 to reach the position of the locking block 13 to complete the locking.

[0026] Example 2, please refer to Figures 1 to 4The adjustment groove 4 has a through groove 23, which is connected to the slot 24 on the top surface of the lower box 3. The bottom surface of the through groove 23 has a sliding groove 25. The bottom surface of the L-shaped block 11 is fixed with a slider 26 that is slidably connected to the sliding groove 25. The L-shaped block 11 inside the slot 24 has an irregularly shaped block 27. The cooperation between the sliding groove 25 and the slider 26 can prevent hard friction between the L-shaped block 11 and the through groove 23, making the pushing smoother.

[0027] The bottom surface of the upper box 2 is fixed with a plug 28. The end of the plug 28 fits into the irregularly shaped block 27. When the L-shaped rod 22 is inserted into the card block 13, there is a gap between the end of the plug 28 and the end of the slot 24. Since the upper box 2 needs to be pushed during disassembly, a gap needs to be left between the plug 28 and the slot 24 for adjustment.

[0028] The top surface of the upper box body 2 is provided with a sealing groove 29, and a box lid 30 is inserted into the sealing groove 29. The lunch box body 1 is provided with a carrying rod 31. The sealing groove 29 is used to prevent internal heat from escaping after the box lid 30 is closed, thus achieving the effect of heat preservation. The carrying rod 31 facilitates the movement of the lunch box body 1.

[0029] The steps of using this utility model are as follows: When it is necessary to disassemble, continue to apply a pushing force in the direction of the semi-circular groove 19. The insert 28 pushes the L-shaped block 11 to move towards the end of the slot 24. When the insert 28 reaches the end of the slot 24, the L-shaped rod 22 disengages from the locking block 13 and is located in the circuit 18. At this time, the pushing force is removed. Under the restoring force of the spring 7, the insert 28 gradually slides out of the slot 24. Under the action of the slider 26, the process can be made smoother, thereby completing the disassembly of the upper box 2 and the lower box 3.
