The manufacturing process is complicated and the connection stability between the handle and the box body cannot be guaranteed. There is a risk that the handle may break or fall off during use. If the handle is not detachable, the gap between the handle and the box body is difficult to clean, which may easily lead to dirt and grime, making it more difficult for users to clean. Utility Model Content

[0003] The present application provides a thermal insulation lunch box to solve the problem that the handle connection of the traditional thermal insulation lunch box is low in stability and difficult to disassemble and assemble.

[0004] The technical solution adopted in this application is:

[0005] A thermal insulation lunch box comprises a barrel body and a handle, wherein one of the barrel body and the handle is provided with a rotation hole, and the other of the barrel body and the handle is provided with a positioning boss matched with the rotation hole, the positioning boss is provided with a stop protrusion, and the barrel body or the handle provided with the rotation hole is also provided with a first avoidance gap connected to the rotation hole; the handle is rotatably installed on the barrel body through the rotation hole and the positioning boss, so as to have an alignment state in which the first avoidance gap is aligned with the stop protrusion, and a misalignment state in which the first avoidance gap is misaligned with the stop protrusion; the thermal insulation lunch box also comprises an adjusting member, the adjusting member having a second avoidance gap matched with the stop protrusion, the adjusting member is rotatably installed on the positioning boss, and the second avoidance gap can be misaligned with the stop protrusion to prevent the handle from detaching from the barrel body when the handle is in the alignment state.

[0006] The thermal insulation lunch box of the present application also includes the following additional technical features:

[0007] The adjusting member comprises an adjusting body and a blocking portion arranged on the adjusting body, the barrel body or the handle is provided with a matching portion, and the blocking portion is engaged with the matching portion to limit the rotation of the adjusting member.

[0008] The barrel body or the handle is provided with a plurality of the matching parts at intervals in the circumferential direction around the rotating hole, and the blocking part selectively cooperates with one of the matching parts to stop.

[0009] The adjusting member further comprises an adjusting portion arranged on the adjusting body, and the adjusting portion protrudes from the adjusting body.

[0010] The adjusting portion and the blocking portion are arranged on two opposite sides of the adjusting body, and the outer surface of at least a part of the blocking portion is a spherical surface.

[0011] The positioning boss is arranged on the barrel body, the rotating hole is arranged on the handle, and the handle is also provided with a concave platform adapted to the adjusting member, and the adjusting member abuts against the concave platform to limit the axial movement of the adjusting member along the rotating hole.

[0012] Along the axial direction of the rotating hole, the adjusting member is clamped and fixed between the stopping protrusion and the concave platform.

[0013] The adjusting member is built into the handle, and the heat-insulating lunch box further comprises a decorative cover installed at the concave platform to cover the adjusting member.

[0014] The barrel body comprises a barrel body and a decorative ring which is formed separately from the barrel body, the decorative ring is installed on the upper part of the barrel body, and the handle is rotatably installed on the decorative ring.

[0015] One of the barrel body and the decorative ring is provided with a boss, and the other is provided with a groove matched with the boss, and the decorative ring is installed on the barrel body through interference fit between the boss and the groove.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. The heat preservation lunch box of the present application comprises a rotating hole provided on one of the barrel body and the handle, and a positioning boss provided on the other of the two, and the rotating connection between the handle and the barrel body is realized by the cooperation between the rotating hole and the positioning boss, and the rotating process of the handle is smooth and not easy to get stuck; and a stopper protrusion is provided on the positioning boss, and a first avoidance notch is connected to the rotating hole, so that the handle has an alignment state in which the first avoidance notch and the stopper protrusion are mutually aligned and a dislocation state in which the first avoidance notch and the stopper protrusion are mutually dislocated. When the stopper protrusion is aligned with the first avoidance notch, the handle can move relative to the barrel body, thereby realizing the installation and removal of the handle. When cleaning the lunch box, the user can first adjust the handle to an aligned state, then take the handle outward, and after disassembling the handle, clean the handle and the edge seams of the barrel body separately, avoiding the hiding of dirt in the connection between the handle and the barrel body, thereby reducing the risk of bacteria breeding and improving the user experience; similarly, when installing the handle, it is only necessary to align the first avoidance notch with the stop protrusion, so that the handle is in an aligned state, and embed the stop protrusion into the first avoidance notch to achieve the installation of the handle.

[0018] In addition, the thermal insulation lunch box of the present application is also provided with an adjustment member rotatably mounted on the positioning boss, and the adjustment member has a second avoidance notch, so that the stop protrusion must be aligned with the first avoidance notch and the second avoidance notch at the same time to achieve the stop protrusion to disengage, and then achieve the separation of the handle from the barrel body. The adjustment member can be adjusted in position, and after adjustment, the second avoidance notch and the stop protrusion are arranged in a staggered manner. When the thermal insulation lunch box is in normal use, as the handle rotates, even if the stop protrusion is aligned with either the first avoidance notch or the second avoidance notch, the stop protrusion must not be aligned with the other, and the stop protrusion cannot be disengaged due to the action of the adjustment member, thereby ensuring the stability of the connection between the handle and the barrel body.

[0019] 2. As a preferred embodiment of the present invention, since the handle is accompanied by a large amount of rotation during use, and the handle will have friction with the adjustment member during the rotation process, by setting the blocking part and the matching part, it can be ensured that the adjustment member will not be deviated under the cooperation of the blocking part and the matching part when the handle is rubbed, thereby ensuring that the second avoidance notch is stably placed in the preset position, preventing the adjustment member from being deviated due to the rotation of the handle so that the second avoidance notch rotates to a position aligned with the stop protrusion, thereby causing the stop protrusion to fall out, and providing a guarantee for the stability of the connection between the handle and the barrel body. In addition, due to the influence of the operating space, it is difficult to intuitively observe the position state of the adjustment part when assembling the adjustment member. By setting the blocking part and the matching part, when the two are successfully aligned, the assembly personnel will be given tactile feedback, prompting the user that the adjustment member has been adjusted into place, saving the user the operation of accurately calibrating the installation position of the adjustment member, reducing the difficulty of assembling the adjustment member, and improving the user's experience.

[0020] 3. As a preferred embodiment of the present invention, the number of matching parts is set to be multiple, so that when the user is assembling the adjusting part, the user can choose to match the blocking part with any one of the stoppers of the multiple matching parts to achieve the misalignment of the second avoidance notch and the stop protrusion, thereby realizing the limiting of the stop protrusion by the adjusting part, so that the user does not need to accurately align the positions of the blocking part and the matching part when assembling the adjusting part, and the installation of the adjusting part can be completed by matching the blocking part with any stopper of the matching part with tactile feedback, which further reduces the difficulty of installing the adjusting part and improves the user's convenience.

[0021] 4. As a preferred embodiment of the present invention, the adjusting member further comprises an adjusting portion provided on the adjusting body, and the adjusting portion protrudes from the adjusting body. By providing the adjusting portion, an operating position is provided for the user to control the movement of the adjusting member. When installing the adjusting member, the user can control the movement of the adjusting member by clamping the adjusting portion so that the second avoidance notch and the stop protrusion are arranged in a staggered manner so that the adjusting member can limit the stop protrusion. When disassembling the adjusting member, the user can control the movement of the adjusting member by clamping the adjusting portion so that the second avoidance notch and the stop protrusion are aligned, thereby realizing the separation of the handle from the barrel body.

[0022] 5. As a preferred embodiment of the present invention, the positioning boss is provided on the barrel body, the rotating hole is provided on the handle, and the handle is also provided with a concave platform adapted to the adjusting member, and the adjusting member abuts against the concave platform to limit the movement of the adjusting member along the axial direction of the rotating hole. By providing the concave platform on the handle, the movement of the adjusting member along the axial direction of the rotating hole is limited, the installation stability of the adjusting member is improved, and the adjustment member is guaranteed to stably realize the limiting function of the stop protrusion, while eliminating the need to provide a limiting member inside the handle specifically for limiting the adjusting member along the axial direction of the rotating hole, thereby optimizing the structural design of the handle.

[0023] 6. As a preferred embodiment of the present utility model, the adjusting member is clamped and fixed between the stop protrusion and the recessed platform, and the recessed platform and the stop protrusion cooperate with each other to limit the adjusting member in two axial directions along the rotating hole. In addition to the function of cooperating with the limit handle, the stop protrusion also integrates the function of the limit adjusting member, and the functions are further integrated, thereby optimizing the structural design of the thermal insulation lunch box.

[0024] 7. As a preferred embodiment of the present invention, the adjustment part is built into the handle, and the heat preservation lunch box also includes a decorative cover installed on the concave platform to cover the adjustment part. By setting the decorative cover, on the one hand, the implicit layout of the adjustment part can be realized, avoiding the adjustment part from being exposed to the user's field of vision, and improving the user's visual experience; on the other hand, the decorative cover can shield the adjustment part, preventing external dust, debris or rice residue from entering the handle to block the adjustment part, while providing protection for the normal operation of the adjustment part and reducing the cleaning pressure of the user, thus improving the user's experience.

[0050] like Figures 1 to 10As shown, an insulated lunch box comprises a barrel body 1 and a handle 2, one of the barrel body 1 and the handle 2 is provided with a rotation hole 3, the other of the two is provided with a positioning boss 4 adapted to the rotation hole 3, the positioning boss 4 is provided with a stop protrusion 41, and the barrel body 1 or the handle 2 provided with the rotation hole 3 is also provided with a first avoidance gap 5 connected to the rotation hole 3; the handle 2 is rotatably installed on the barrel body 1 through the rotation hole 3 and the positioning boss 4, so as to have an alignment state in which the first avoidance gap 5 is aligned with the stop protrusion 41, and a dislocation state in which the first avoidance gap 5 is dislocated with the stop protrusion 41; the insulated lunch box also comprises an adjusting member 6, the adjusting member 6 has a second avoidance gap 61 adapted to the stop protrusion 41, the adjusting member 6 is rotatably installed on the positioning boss 4, and the second avoidance gap 61 can be arranged displaced with the stop protrusion 41 to prevent the handle 2 from detaching from the barrel body 1 when the handle 2 is in the alignment state.

[0051] The heat preservation lunch box of the present application comprises a rotating hole 3 provided on one of the barrel body 1 and the handle 2, and a positioning boss 4 provided on the other of the two. The rotating hole 3 cooperates with the positioning boss 4 to realize the rotation connection between the handle 2 and the barrel body 1, and the rotation process of the handle 2 is smooth and not easy to get stuck; and a stopper protrusion 41 is provided on the positioning boss 4, and a first avoidance notch 5 is connected to the rotating hole 3, so that the handle 2 has an alignment state in which the first avoidance notch 5 and the stopper protrusion 41 are mutually aligned and a dislocation state in which the first avoidance notch 5 and the stopper protrusion 41 are mutually dislocated. When the stopper protrusion 41 is aligned with the first avoidance notch 5, the handle 2 can move relative to the barrel body 1, thereby realizing the installation and removal of the handle 2. When cleaning the lunch box, the user can first adjust the handle 2 to the aligned state, then take the handle outward, and after removing the handle 2, clean the handle 2 and the edge seams of the barrel body 1 respectively, avoiding the hiding of dirt at the connection between the handle 2 and the barrel body 1, thereby reducing the risk of breeding bacteria and improving the user's experience; similarly, when installing the handle 2, it is only necessary to align the first avoidance notch 5 with the stop protrusion 41, so that the handle 2 is in an aligned state, and the stop protrusion 41 is embedded in the first avoidance notch 5 to achieve the installation of the handle 2. In addition, the thermal insulation lunch box of the present application is also provided with an adjustment member 6 rotatably mounted on the positioning boss 4, and the adjustment member 6 has a second avoidance notch 61, so that the stop protrusion 41 must be aligned with the first avoidance notch 5 and the second avoidance notch 61 at the same time to achieve the disengagement of the stop protrusion 41, and then the separation of the handle 2 from the barrel body 1 is achieved. The position of the adjusting member 6 can be adjusted. After the adjustment, the second avoidance gap 61 can be arranged in an offset manner with the stop protrusion 41. When the thermal insulation lunch box is in normal use, as the handle 2 rotates, even if the stop protrusion 41 is aligned with either the first avoidance gap 5 or the second avoidance gap 61, the stop protrusion 41 must be misaligned with the other one. The stop protrusion 41 cannot be detached from the first avoidance gap 5 due to the action of the adjusting member 6, thereby ensuring the stability of the connection between the handle 2 and the barrel body 1.

[0052] The present application does not limit the positioning method of the adjusting member 6, which can be any one of the following embodiments:

[0053] Embodiment 1: The adjusting member is threadedly connected to the barrel body 1 or the handle 2 . When the adjusting member 6 is tightened with the barrel body 1 or the handle 2 , the second avoidance notch 61 is misaligned with the stop protrusion 41 .

[0054] Embodiment 2: A first magnetic part is provided on the adjusting part 6, and a second magnetic part with a magnetic property opposite to that of the first magnetic part is provided on the barrel body 1 or the handle 2. The adjusting part 6 is connected to the barrel body 1 or the handle 2 through the magnetic attraction cooperation between the first magnetic part and the second magnetic part. When the first magnetic part and the second magnetic part are magnetically locked, the second avoidance notch 61 is misaligned with the stop protrusion 41.

[0055] Implementation method three: Figure 4 , Figure 5 , Figure 8 As shown, the adjusting member 6 includes an adjusting body 62 and a blocking portion 63 provided on the adjusting body 62 , the barrel body 1 or the handle 2 is provided with a matching portion 21 , and the blocking portion 63 cooperates with the matching portion 21 to limit the rotation of the adjusting member 6 . Since the handle 2 is accompanied by a lot of rotation during use, and the handle 2 will have friction with the adjustment member 6 during the rotation process, by providing the blocking portion 63 and the matching portion 21, it can be ensured that the adjustment member 6 will not be displaced under the cooperation of the blocking portion 63 and the matching portion 21 when the handle 2 rubs against it, thereby ensuring that the second avoidance notch 61 is stably placed in the preset position, preventing the adjustment member 6 from being displaced due to the rotation of the handle 2 so that the second avoidance notch 61 rotates to a position aligned with the stop protrusion 41, thereby causing the stop protrusion 41 to fall out, providing a guarantee for the stability of the connection between the handle 2 and the barrel body 1; in addition, due to the influence of the operating space, it is difficult to intuitively observe the position state of the adjustment portion 64 when assembling the adjustment member 6. By providing the blocking portion 63 and the matching portion 21, when the two are successfully aligned, the assembler will be given tactile feedback, prompting the user that the adjustment member 6 has been adjusted into place, saving the user the operation of accurately calibrating the installation position of the adjustment member 6, reducing the difficulty of assembling the adjustment member 6, and improving the user's experience. This embodiment does not limit the setting position of the matching portion 21. Figure 5 The matching portion 21 shown in FIG. 1 is arranged on the handle 2 .

[0056] As a preferred embodiment of the third embodiment, Figure 4 , Figure 5As shown, the barrel body 1 or the handle 2 is provided with a plurality of the matching parts 21 at intervals around the rotating hole 3, and the blocking part 63 selectively matches with one of the matching parts 21. The number of matching parts 21 is set to be multiple, so that when the user assembles the adjustment member 6, the blocking part 63 can be selected to match with any one of the multiple matching parts 21 to achieve the misalignment of the second avoidance notch 61 and the stop protrusion 41, thereby achieving the limit of the stop protrusion 41 by the adjustment member 6, so that when the user assembles the adjustment member 6, there is no need to accurately align the blocking part 63 with the matching part 21. The blocking part 63 can be matched with any matching part 21 by tactile feedback to complete the installation of the adjustment member 6, which further reduces the difficulty of installing the adjustment member 6 and improves the user's convenience.

[0057] As another preferred embodiment under the third embodiment, Figure 7 As shown, the adjusting member 6 also includes an adjusting portion 64 provided on the adjusting body 62, and the adjusting portion 64 protrudes from the adjusting body 62. By providing the adjusting portion 64, an operating position is provided for the user to control the movement of the adjusting member 6. When installing the adjusting member 6, the user can control the movement of the adjusting member 6 by clamping the adjusting portion 64 so that the second avoidance notch 61 and the stop protrusion 41 are misaligned so that the adjusting member 6 can limit the stop protrusion 41. When disassembling the adjusting member 6, the user can control the movement of the adjusting member 6 by clamping the adjusting portion 64 so that the second avoidance notch 61 and the stop protrusion 41 are aligned, thereby realizing the separation of the handle 2 and the barrel body 1. This embodiment does not limit the structural form of the adjusting portion 64, which can be as follows: Figure 7 The columnar structure shown may also be a block structure, a thin sheet structure, etc.

[0058] As a preferred example under this embodiment, Figure 8 As shown, the adjusting portion 64 and the blocking portion 63 are arranged on two opposite sides of the adjusting body 62, and the outer surface of at least part of the blocking portion 63 is a spherical surface. The adjusting portion 64 is arranged to be located on the side of the adjusting body 62 away from the blocking portion 63, so that the user can adjust the position of the adjusting member 6 through the adjusting portion 64, and the outer surface of at least part of the blocking portion 63 is arranged to be a spherical surface, which can reduce the friction force when the adjusting member 6 moves relative to the handle 2 or the barrel body 1, thereby reducing the resistance when the user adjusts the position of the adjusting member 6 and improving the user's experience. Furthermore, the matching portion 21 is the sunken grooves arranged at intervals around the rotating hole 3 in the circumferential direction, and the inner wall surface of the sunken groove is arc-shaped, so as to cooperate with the blocking portion 63. When the adjusting member 6 is assembled and rotated relative to the handle 2 so that the second avoidance notch 61 can be misaligned with the stop protrusion 41, the rotation resistance is reduced and the assembly efficiency is improved.

[0059] As a preferred embodiment of the present application, Figure 4 , Figure 5 As shown, the positioning boss 4 is provided on the barrel body 1, the rotating hole 3 is provided on the handle 2, and the handle 2 is further provided with a concave platform 22 adapted to the adjusting member 6, and the adjusting member 6 abuts against the concave platform 22 to limit the axial movement of the adjusting member 6 along the rotating hole 3. By providing the concave platform 22 on the handle 2, the axial movement of the adjusting member 6 along the rotating hole 3 is limited, the installation stability of the adjusting member 6 is improved, and the adjustment member 6 is guaranteed to stably realize the limiting function of the stop protrusion 41, while eliminating the need to provide a limiting member inside the handle 2 specifically for limiting the adjusting member 6 along the axial direction of the rotating hole 3, thereby optimizing the structural design of the handle 2.

[0060] As a preferred embodiment of this implementation, Figures 2 to 5 As shown, along the axial direction of the rotating hole 3, the adjusting member 6 is clamped and fixed between the stop protrusion 41 and the concave platform 22. The adjusting member 6 is clamped and fixed between the stop protrusion 41 and the concave platform 22, and the concave platform 22 cooperates with the stop protrusion 41 to limit the adjusting member 6 in two directions along the axial direction of the rotating hole 3. In addition to the function of cooperating with the limit handle 2, the stop protrusion 41 also integrates the function of the limit adjusting member 6, and the functions are further integrated, which optimizes the structural design of the thermal insulation lunch box.

[0061] As another preferred embodiment of this embodiment, Figure 1 , Fig. 9 As shown, the adjusting member 6 is built into the handle 2, and the heat preservation lunch box further includes a decorative cover 7 installed at the concave platform 22 to cover the adjusting member 6. By providing the decorative cover 7, on the one hand, the implicit layout of the adjusting member 6 can be realized, and the adjusting member 6 is prevented from being exposed to the user's field of vision, thereby improving the user's visual experience; on the other hand, the decorative cover 7 can shield the adjusting member 6, preventing external dust, debris or rice residue from entering the handle 2 to block the adjusting member 6, thereby ensuring the normal operation of the adjusting member 6 and reducing the cleaning pressure of the user, thereby improving the user's experience.

By setting the decorative ring 12, on the one hand, a mounting position connected to the barrel body 1 is provided for the handle 2; on the other hand, during manufacturing and processing, the barrel body 11 and the decorative ring 12 can be formed separately and then assembled, which optimizes the structural design of the thermal insulation lunch box; in addition, when cleaning the thermal insulation lunch box, if necessary, the decorative ring 12 and the handle 2 can be removed from the barrel body 11 together and the barrel body 11 can be cleaned, which saves the operation of separating the handle 2 from the barrel body 1 and increases the user experience. Of course, it is also possible to not set the decorative ring 12, and the handle 2 can be directly rotatably installed on the barrel body 1, and this application does not limit this.

[0063] As a preferred embodiment of this implementation, Fig. 9 , Fig.10 As shown, one of the barrel body 11 and the decorative ring 12 is provided with a boss 111, and the other is provided with a groove 121 adapted to the boss 111, and the decorative ring 12 is installed on the barrel body 11 through the interference fit of the boss 111 and the groove 121. The decorative ring 12 and the barrel body 11 are assembled into one by the interference fit of the boss 111 and the groove 121, which reduces the difficulty of disassembling and assembling the decorative ring 12 and the barrel body 11, so that the user can more easily separate or install the decorative ring 12 from the barrel body 11, thereby improving the user's use experience.

[0064] The present embodiment does not limit the connection method between the decorative ring 12 and the barrel body 11. The two can also be connected by threads, or a positioning protrusion is provided on one of the decorative ring 12 and the barrel body 11, and the other is provided with a positioning groove matched with the positioning protrusion, and the decorative ring 12 and the barrel body 11 are connected by plugging and fitting the positioning protrusion and the positioning groove, or other suitable connection methods are adopted, all of which are within the protection scope of the present application.
