Description

Technical Field

[0001] This application belongs to the field of thermal box technology, and in particular relates to a press-type easy-open thermal box. Background Technology

[0002] Most insulated soft cases currently on the market use waterproof zippers and Velcro, which provide good sealing to protect the internal fillings and items that need to be kept warm. While these structures are widely used and the connections are relatively secure, users need to repeatedly open and close the zippers or fasten the Velcro during use, which is inconvenient and physically demanding, resulting in a less than ideal user experience. Therefore, there is a need to design an insulated case that is easy to open and close. Summary of the Invention

[0003] To achieve the above objectives, this application provides a press-type easy-open insulated box, including a box cover and a box body forming a box-shaped structure. The box cover includes a cover body, a button, a reciprocating component, and a sealing component. The button is movably disposed on the cover body and can control the reciprocating component to switch between a pop-up state and a compressed state. The sealing component includes a sealing cover, a sealing seat, and a sealing ring disposed on the outer periphery of the sealing cover.

[0004] The sealing seat is disposed on the housing, and the sealing cover is connected to the reciprocating component. The reciprocating component drives the sealing cover and the sealing ring to move, thereby switching the engagement state of the sealing ring and the sealing seat to a sealed state or a non-sealed state.

[0005] The enclosure includes enclosure walls and enclosure bottom, and both the enclosure walls and enclosure bottom include at least an outer shell layer and an enclosure insulation layer from the outside to the inside.

[0006] Preferably, the reciprocating component includes a chassis, an elastic element, and a support arm;

[0007] The chassis is located at the lower end of the cover and has a protruding post that penetrates the cover. The support arm includes a support arm rod and a support arm base, and the protruding post is connected to the support arm base.

[0008] The elastic element is disposed between the cover and the chassis, and applies an elastic force to the chassis away from the cover.

[0009] The support arm abuts against the button and applies a spring force away from the cover to the button. The button and the cover are provided with matching limiting structures, which prevent the button from being bounced off by the support arm.

[0010] The chassis, cover, and button are provided with a misaligned structure that cooperates with each other. The misaligned structure causes the chassis to reciprocate in the vertical direction in response to the pressing frequency when the button is pressed.

[0011] Preferably, the misalignment structure includes:

[0012] A button fixing post and a rotor are disposed on the button and facing one end of the reciprocating component. The rotor can rotate around the button fixing post. The rotor is provided with a plurality of wedge-shaped members. The outer side of the wedge-shaped members facing the reciprocating component has a first guide surface and the inner side has a second guide surface. The end of the wedge-shaped members away from the reciprocating component has a third guide surface. The wedge-shaped members have a first guide groove inside and a second guide groove between the wedge-shaped members.

[0013] A cover fixing post is provided on the cover and faces the button. The cover fixing post has a through hole in the middle. A plurality of cover misalignment wedges are provided on the wall of the through hole. The cover misalignment wedges are provided with cover guide surfaces. Cover guide grooves are provided between the cover misalignment wedges.

[0014] A chassis fixing post is provided on the chassis and at one end facing the cover. The chassis fixing post is provided with a plurality of chassis misalignment wedges. The chassis misalignment wedges are provided with chassis guide surfaces. Chassis guide grooves are provided between the chassis misalignment wedges.

[0015] The misaligned wedge of the cover and the misaligned wedge of the chassis cooperate to cause the rotor to rotate when it travels to the guide surface of the cover and the guide surface of the chassis, respectively.

[0016] Preferably, the cover guide surface includes an upper guide surface and a lower guide surface, both of which are provided with inclined or curved surfaces for guiding purposes.

[0017] Preferably, the displacement change of the reciprocating component includes a compressed state and a spring-up state;

[0018] When the button is pressed, the button fixing post drives the rotor to move downward. When the rotor passes through the through hole and abuts against the chassis misalignment wedge, the chassis guide surface contacts the second guide surface and then places the chassis misalignment wedge into the first guide groove through the matching inclined surface. When the button is released, the elastic element applies a spring force away from the cover to the chassis, and the chassis drives the support arm to move upward and pops the button up. The rotor follows the button to move upward. When the rotor abuts against the cover misalignment wedge, the cover guide surface contacts the third guide surface and then locks the rotor onto the chassis misalignment wedge through the matching inclined surface. At this time, it is in a compressed state.

[0019] When the button is pressed again, the rotor abuts against the chassis misalignment wedge again. After the chassis guide surface contacts the second guide surface, the wedge-shaped member is placed into the chassis guide groove through the matching inclined surface. When the button is released, the elastic member applies a spring force away from the cover to the chassis. The chassis will drive the support arm to move upward and pop up the button. The rotor moves upward with the button. When the rotor abuts against the cover misalignment wedge, after the cover guide surface contacts the third guide surface, the wedge-shaped member is introduced into the cover guide groove through the matching inclined surface and the rotor continues to move upward until the limiting structure is triggered. At this time, it is in the pop-up state.

[0021] Preferably, the outer periphery of the cover is provided with a raised edge, and the sealing ring is inclined outward and upward from the sealing cover;

[0022] When the reciprocating component is in a compressed state, the chassis drives the sealing cover and sealing ring to move closer to the cover body. The sealing ring deforms under the action of the convex edge, expands outward, and increases the contact area with the sealing seat, thus achieving a sealed state.

[0023] When the reciprocating component is in the pop-up state, the chassis drives the sealing cover and sealing ring away from the cover body. The sealing ring at least partially recovers its deformation, retracts inward, and reduces the contact area with the sealing seat. At this time, it is in a non-sealed state.

[0024] Preferably, the sealing cap is detachably connected to the reciprocating component, and the sealing ring is detachably connected to the sealing cap.

[0025] Preferably, the sealing seat and the housing are fitted in any of the following ways:

[0031] The movable part includes a clamping member and a sliding member. The clamping member is connected to the sliding member, and the clamping member is provided with an expansion spring to keep the clamping member in an open state.

[0032] The main body has a sliding member embedded within it, and a locking hook is provided within the main body.

[0034] A connector that matches the clamping member and can be clamped and fixed by the clamping member;

[0035] The sliding member is provided with a reciprocating groove and a hook. The hook is hook-shaped or heart-shaped. The reciprocating groove is located around the hook. The locking hook can reciprocate within the reciprocating groove.

[0036] Preferably, the insulation layer of the enclosure is any one of the following:

[0037] The insulation layer of the box is configured as one of the following: sponge, silica aerogel, glass fiber, pearl cotton, EVA, aluminum foil cotton, and rubber and plastic materials;

[0038] The insulation layer of the box is unfilled and is an air-filled structure.

[0039] The insulation layer of the box is filled with a brushed material, which is an inflatable brushed structure.

[0040] Preferably, it also includes a lid insulation layer disposed at the bottom of the lid, wherein the lid insulation layer is configured in any of the following ways:

[0041] The insulation layer of the box lid includes a shell fabric and a filling material, wherein the filling material is configured as one of sponge, silica aerogel, glass fiber, pearl cotton, EVA, aluminum foil cotton, and rubber and plastic materials;

[0045] Preferably, the cover or button has a handle on top.

[0046] Preferably, the handle is disposed on the button, and the top of the button is provided with a receiving groove for fitting the handle.

[0047] Preferably, the lid and the body of the box are provided with a hinge device, and the lid can be opened from the body of the box around the hinge device.

[0048] Preferably, the hinge device is provided with a hinge elastic element, which applies an elastic force to the lid to separate it from the box body.

[0049] Preferably, the sealing seat is provided with a buffer layer, which is used to buffer the pressure of the sealing ring contacting the sealing seat and improve the sealing performance.

[0050] Preferably, the buffer layer is configured in the unsealed state in any of the following ways:

[0051] The buffer layer is an arc-shaped layer made of an elastic material, which causes the gap between the cover and the sealing seat to gradually decrease or the contact area to gradually increase when the cover is closed.

[0052] The buffer layer is an arc-shaped layer made of several layers of materials with different elasticity. The elasticity of the buffer layer is weaker towards the lower end. When the cover is closed, the gap between the cover and the sealing seat gradually decreases or the contact area gradually increases.

[0053] The buffer layer has a corrugated or pleated transition edge, which makes the contact force between the cover and the sealing seat gradually uniform when the cover is closed.

[0054] The buffer layer is a liquid or gel, and the buffer layer makes the contact force between the cover and the sealing seat gradually uniform when the cover is closed;

[0055] The buffer layer is a transition edge with a honeycomb structure, which causes the gap between the cover and the sealing seat to gradually decrease or the contact area to gradually increase when the cover is closed.

[0056] The beneficial effects of this application are as follows: This application provides a press-type easy-open insulated box. By setting an easy-open lid, users can quickly open and close the box by pressing it. This ensures that the insulated box has a sealing effect, achieves a good insulation effect through the insulation structure, and is convenient and quick to use, thus improving the user experience. It is suitable for daily shopping as well as for light outdoor enthusiasts, and has a wider market and target audience. Attached Figure Description

[0095] Example 1

[0096] like Figure 1-14 As shown, this embodiment provides a push-to-open insulated box, including a box cover 1 and a box body 2 forming a box-shaped structure. The box cover 1 includes a cover body 11, a button 12, a reciprocating component 13, and a sealing component 14. The button 12 is movably disposed on the cover body 11 and can control the reciprocating component 13 to switch between a pop-up state and a compressed state. The sealing component 14 includes a sealing cover 141, a sealing seat 142, and a sealing ring 143 disposed on the outer periphery of the sealing cover 141. The sealing seat 142 is disposed on the box body 2. The sealing cover 141 is connected to the reciprocating component 13. The reciprocating component 13 drives the sealing cover 141 and the sealing ring 143 to move, thereby switching the engagement state of the sealing ring 143 and the sealing seat 142 to a sealed state or a non-sealed state. The box body 2 includes a box wall 21 and a box bottom 22. The box wall 21 and the box bottom 22 each include at least an outer shell layer and a box body 2 insulation layer from the outside to the inside.

[0097] The method of use of this application is as follows: when it is necessary to close the lid 1, the lid 1 is first naturally closed to the position of the box body 2. At this time, although it is in a closed state, since there are no other fixing objects between the lid 1 and the box body 2, the lid 1 is easy to fall off the box body 2 when there is shaking or inversion. Therefore, by pressing the button 12, the reciprocating component 13 is switched to a compression state, which drives the sealing cover 141 to move and causes the sealing ring 143 to deform and expand outward. At this time, because the pressure of the sealing ring 143 on the sealing seat 142 is greater, the friction is also greater. At the same time, due to the action of the sealing ring 143, a relatively sealed space is formed inside the box body 2. The atmospheric pressure makes the fixation between the lid 1 and the box body 2 more stable. At this time, the cooperation state between the sealing ring 143 and the sealing seat 142 is a sealed state. In addition, during the pressing of button 12, some of the gas in the lid 1 and the body 2 is squeezed out, reducing excess gas. When a complete seal is achieved, the sealing cover 141 is displaced upward, making the gas inside the body 2 thinner and the air pressure lower, while the air pressure outside the body 2 is greater. Therefore, atmospheric pressure will push the lid 1 inward, making the lid 1 and the body 2 more tightly closed.

[0098] When it is necessary to open the lid 1, the button 12 can be pressed. The button 12 switches the reciprocating part 13 to the pop-up state, thereby causing the sealing cover 141 to move and the sealing ring 143 to return to its original shape. At this time, since the pressure of the sealing ring 143 on the sealing seat 142 is reduced or even no longer in contact, the friction is reduced or there is no friction. The sealing effect of the sealing ring 143 is reduced, or the pressure difference between the inside and outside can be broken with a small amount of force, so that the atmospheric pressure inside and outside the box 2 is the same. The lid 1 can be easily separated from the box 2. At this time, the sealing ring 143 and the sealing seat 142 are in a non-sealed state.

[0099] The outer shell layer of this application can be made of materials such as TPU composite fabric, PVC composite fabric, PU composite fabric, Oxford cloth, and nylon, which have good durability. The reciprocating component 13 used in this application can be a reciprocating pressing component such as a press-type spring mechanism or a ratchet-pawl mechanism, which is not limited to the embodiments listed in this application. In addition, in terms of the engagement method, the reciprocating component 13 can be in a non-sealed state when compressed and in a non-sealed state when spring-up. The specific configuration depends on the reciprocating component 13 used. As long as the sealed state can be switched through the reciprocating component 13, it is within the protection scope of this application.

[0100] Example 2

[0101] In this embodiment, reference Figure 3-9 The reciprocating component 13 used includes a chassis 131, an elastic element 132, and a support arm 133.

[0102] A chassis 131 is located at the lower end of the cover 11. The chassis 131 has a protrusion 1311 penetrating the cover 11. The support arm 133 includes a support arm rod 1331 and a support arm base 1332, with the protrusion 1311 connected to the support arm base 1332. An elastic element 132 is disposed between the cover 11 and the chassis 131, applying an elastic force away from the cover 11 to the chassis 131. The support arm rod 1331 abuts against the button 12. Due to the elastic force transmission of the elastic element 132, the support arm rod 1331 applies an elastic force away from the cover 11 to the button 12. The button 12 and the cover 11 are provided with mutually matching limiting structures 15, which prevent the button 12 from being springed away by the support arm rod 1331.

[0103] The chassis 131, cover 11, and button 12 are provided with a mutually cooperating misalignment structure 16. The misalignment structure 16 causes the chassis 131 to reciprocate in the vertical direction in response to the pressing frequency when the button 12 is pressed. The misalignment structure 16 includes:

[0104] A button fixing post 121 and a rotor 122 are provided on the button 12 at one end facing the reciprocating component 13. The rotor 122 can rotate around the button fixing post 121. The rotor 122 is provided with a plurality of wedge-shaped members 123. The outer side of the wedge-shaped member 123 facing the reciprocating component 13 is provided with a first guide surface 124, the inner side is provided with a second guide surface 125, the end of the wedge-shaped member 123 away from the reciprocating component 13 is provided with a third guide surface 126, the wedge-shaped member 123 is provided with a first guide groove 127, and the wedge-shaped members 123 are provided with a second guide groove 128.

[0105] A cover fixing post 111 is set on the cover 11 and faces the button 12. The cover fixing post 111 has a through hole 112 in the middle. A number of cover misalignment wedges 113 are provided on the wall of the through hole 112. The cover misalignment wedges 113 have cover guide surfaces 114. Cover guide grooves 115 are provided between the cover misalignment wedges 113.

[0106] A chassis fixing post 134 is set on the chassis 131 and faces the cover 11. The chassis fixing post 134 is provided with a plurality of chassis misalignment wedges 135. The chassis misalignment wedges 135 are provided with chassis guide surfaces 136. Chassis guide grooves 137 are provided between the chassis misalignment wedges 135.

[0107] The cover misalignment wedge 113 and the chassis misalignment wedge 135 cooperate to make the rotor 122 rotate when it travels to the cover guide surface 114 and the chassis guide surface 136 respectively.

[0108] More specifically, the displacement changes of the reciprocating component 13 include a compressed state and a spring-up state;

[0109] like Figure 10-11 As shown, when button 12 is pressed, button fixing post 121 drives rotor 122 and wedge 123 to move downward (state A-1). When wedge 123 passes through through hole 112 and abuts against chassis misalignment wedge 135, chassis guide surface 136 contacts second guide surface 125 (state A-2), and chassis misalignment wedge 135 is placed into first guide groove 127 through matching inclined surface (states A-3, A-4). When button 12 is released, elastic element 132 applies force to chassis 131 away from cover 1. The elastic force of 1 causes the chassis 131 to drive the support arm 1331 to move upward and pop up the button 12. The rotor 122 and the wedge 123 follow the button 12 to move upward (state A-4). When the wedge 123 abuts against the cover misalignment wedge 113 (state A-5), after the cover guide surface 114 contacts the third guide surface 126, the wedge 123 will be engaged on the cover misalignment wedge 113 through the matching inclined surface (state A-6). At this time, the button 12 is not popped up, and the reciprocating component 13 is in a compressed state.

[0110] like Figure 12-13As shown, when the wedge 123 is stationary (state A-6 or state B-1), when button 12 is pressed again, the rotor 122 and the wedge 123 move downwards again to abut against the chassis misalignment wedge 135 (state B-2). After the chassis guide surface 136 contacts the second guide surface 125, the wedge 123 will be placed into the chassis guide groove 137 through the matching inclined surface (states B-3 and B-4). When button 12 is released, the elastic element 132 applies a spring force away from the cover 11 to the chassis 131, and the chassis 131 will drive the support arm 1331 to move upwards and pop up the button 12. The rotor 122 and the wedge 123 move upward following the button 12. When the wedge 123 abuts against the cover misalignment wedge 113, the cover guide surface 114 contacts the third guide surface 126 (state B-5). The wedge 123 will be introduced into the cover guide groove 115 through the matching inclined surface (state B-6). Since the cover guide groove 115 is straight and unobstructed, the elastic force will cause the rotor 122 to continue to move upward until the limit structure 15 is triggered (state B-7). The button 12 can no longer move upward. At this time, the button 12 is popped up, and the reciprocating component 13 is in the popped-up state.

[0111] Example 3

[0112] like Figure 14 As shown, the cover guide surface 114 includes an upper cover guide surface 1141 and a lower cover guide surface 1142. Both the upper cover guide surface and the lower cover guide surface 1142 are provided with inclined or curved surfaces for guiding purposes.

[0113] In Embodiment 2, the statements "when the rotor 122 abuts against the cover misalignment wedge 113, after the cover guide surface 114 contacts the third guide surface 126, the rotor 122 will be engaged on the chassis misalignment wedge 135 through the matching inclined surface" and "when the rotor 122 abuts against the cover misalignment wedge 113, after the cover guide surface 114 contacts the third guide surface 126, the wedge-shaped piece 123 will be introduced into the cover guide groove 115 through the matching inclined surface" refer to the function of the cover guide surface 1142 at the lower end of the cover in this embodiment.

[0114] Unlike Embodiment 2, this embodiment also includes an upper guide surface 1141 for the cover, which guides the rotor 122 smoothly into the cover guide groove 115. Without the upper guide surface 1141, the rotor 122 may come into contact with the top of the cover misalignment wedge 113 as it moves downwards. If the top of the cover misalignment wedge 113 is flat and has high friction, it will prevent the rotor 122 from continuing to move downwards and will not be able to press further. With the upper guide surface 1141, when the rotor 122 moves downwards, the first guide surface 124 of the wedge-shaped member 123 contacts the upper guide surface of the cover. Since both are wedge-shaped structures, and the upper guide surface 1141 has a guiding slope or arc surface, it guides the rotor 122 to adjust its rotation angle to more appropriately enter the cover guide groove 115, improving the device's fault tolerance and service life.

[0115] Example 4

[0116] In this embodiment, as Figure 9 As shown, the bottom of the button 12 is also provided with a slide rail 129, the support arm 1331 is "L" shaped and abuts against the slide rail 129, and the support arm base 1332 is a triangular prism and is set on the cover 11.

[0117] The slide rail 129 at the bottom of button 12 can raise the support arm 1331 to a certain height, reducing the contact area between the support arm 1331 and button 12, thereby reducing the frictional resistance when pressing and making the pressing process smoother.

[0118] The "L"-shaped support arm 1331 can increase the contact range between the support arm 1331 and the button 12, thereby ensuring uniform force distribution. Compared with point contact, line contact or surface contact can improve the stability of the button 12 when pressed, distribute the elastic force of the support arm 1331 on the button 12 evenly, and distribute the pressure of the button 12 on the support arm 1331 evenly, thereby improving service life and stability.

[0119] Example 5

[0120] In this embodiment, as Figure 3 As shown, the outer periphery of the cover 11 is provided with a raised edge 116, and the sealing ring 143 is inclined outward and upward from the sealing cover 141. The raised edge 116 can increase the contact area with the sealing seat 142 under compression, thereby enhancing the sealing effect.

[0121] When the reciprocating component 13 is in a compressed state, the chassis 131 drives the sealing cover 141 and the sealing ring 143 to move closer to the cover body 11. The sealing ring 143 deforms under the action of the protruding edge 116, expands outward and increases the contact area with the sealing seat 142, and is in a sealed state at this time.

[0122] When the reciprocating component 13 is in the pop-up state, the chassis 131 drives the sealing cover 141 and the sealing ring 143 away from the cover body 11. The sealing ring 143 recovers at least part of its deformation, retracts inward and reduces the contact area with the sealing seat 142, and is in a non-sealed state at this time.

[0123] Example 6

[0124] In this embodiment, the sealing cap 141 is detachably connected to the reciprocating component 13, and the sealing ring 143 is detachably connected to the sealing cap 141. To ensure sealing and heat insulation, the sealing ring 143 is typically made of elastomers such as rubber, silicone, or latex. These materials often suffer from aging problems. Therefore, detachably connecting the sealing cap 141 to the reciprocating component 13 and detachably connecting the sealing ring 143 to the sealing cap 141 facilitates both cleaning and replacement.

[0125] The detachable connection between the sealing cover 141 and the reciprocating component 13, and between the sealing ring 143 and the sealing cover 141, can be selected from conventional detachable methods such as snap-fit ​​connection and threaded connection.

[0126] Example 7

[0127] In this embodiment, the sealing seat 142 and the housing 2 can be matched in any of the following ways:

[0128] Method 1, such as Figure 15 As shown, the sealing seat 142 is frame-shaped and connected to the box body 2. In this method, the frame-shaped sealing seat 142 is only set on the top of the box body 2, and the lower part of the box body 2 can use soft materials such as inflatable bags or sponge bags to achieve better compression for easy carrying.

[0129] Method 2, such as Figure 16 As shown, the sealing seat 142 is cylindrical, and at least a portion of the sealing seat 142 is embedded inside the housing 2. In this way, the sealing seat 142 is cylindrical, including rigid side walls and a base, which has good hardness and texture, and can protect the inside of the housing 2 from being scratched by sharp objects.

[0130] Example 8

[0131] In this embodiment, a safety latch 4 is also provided on the lid 1 and the body 2. The safety latch 4 is used to prevent accidental opening. To prevent the lid from falling off due to accidental drops during transportation and use, an additional safety latch 4 can be added. The safety latch 4 can be any safety latch in the prior art, as long as it can serve the purpose of fixing the connection.

[0132] Specifically in this embodiment, refer to Figure 17-18The safety latch 4 includes a latch 41 and a movable locking member 42. The movable locking member can be pressed or moved to put the latch in a restricted or unrestricted state. The latch positions shown in the two attached figures are different, but the principle is the same. For example Figure 18 The movable locking element 42 contains a spring. Under the action of the spring force, the movable locking element 42 restricts the movement of the fixed locking tongue 41. When the user needs to open the cover, the spring can be deformed by pressing or flicking, thereby releasing the locking tongue 41 from the restricted state, and thus the cover 1 can be opened. The locking tongue 41 and the movable locking element 42 can be respectively set on the cover 1 and the box body 2, or their positions can be interchanged. The safety latch 4 can also use other methods in the prior art, which are also within its own protection scope.

[0133] Example 9

[0134] In this embodiment, as Figure 19-22 As shown, it also includes a self-locking push-button 3 disposed on the cover 11 and the box 2. The self-locking push-button 3 includes:

[0135] The movable part 31 includes a clamping member 311 and a sliding member 312. The clamping member 311 is connected to the sliding member 312. The clamping member 311 is provided with an expansion spring so that the clamping member 311 is kept in an open state.

[0136] The main body 32 has a sliding member 312 embedded in it, and a locking hook 321 is provided inside the main body 32.

[0137] The elastic part 33 has one end abutting the bottom of the main body part 32 and the other end abutting the movable part 31. The movable part 31 slides outward under the action of elastic force. The main body part 32 and the sliding member 312 are provided with a limiting structure 34 to limit the sliding member 312 from popping out.

[0138] Connector 35 is matched with clamp 311 and can be clamped and fixed by clamp 311;

[0139] The sliding member 312 is provided with a reciprocating groove 36 and a hook 37. The hook 37 is hook-shaped or heart-shaped. The reciprocating groove 36 is located around the hook 37, and the locking hook 321 can reciprocate within the reciprocating groove 36. The reciprocating groove 36 has a guide surface that is higher on the left and lower on the right, or it has a blocking section. The blocking section prevents the locking hook 321 from crossing the section and causes it to slide in a preset direction. Preferably, the locking hook 321 should have elastic deformation so that the locking hook 321 continuously has an elastic force to deflect to the left.

[0140] The self-locking push-button 3 is used as follows:

[0141] refer to Figure 21-22 In the initial state, the self-locking push button 3 is in position. Figure 21-1In the current state, the locking hook 321 is not in the reciprocating slide groove 36 (position A). Press the connector 35 to move downward. As the connector 35 moves downward against the slider 312, the locking hook 321 gradually enters the reciprocating slide groove 36 and moves upward (position B). Due to the guide surface that is higher on the left and lower on the right and the action of the hook 37, the locking hook 321 will move to the upper right. When it moves to the highest point of the right shoulder of the reciprocating slide groove 36 (position C), the locking hook 321 can no longer move upward, the slider 312 can no longer move downward, and the clamping member 311 retracts under the action of the side wall of the main body 32, clamping the connector 35 into the interior of the main body 32. At this point, releasing the pressure releases the self-locking snap fastener 3, causing the sliding member 312 to move upwards under the elastic force. The reciprocating groove 36 guides the locking hook 321 into the lowest point (position D) in the middle of the hook 37. Because the locking hook 321 restricts the sliding member 312 from continuing to move upwards, the sliding member 312 on the force-bearing platform is at a relative standstill. The clamping member 311 and the connector 35 are still inside the main body 32. The side wall of the main body 32 restricts the clamping part from opening, thereby fixing the connector 35. The self-locking snap fastener 3 is in a state of... Figure 21-2 The state.

[0142] Press the connector 35 down again. Since the left shoulder of the reciprocating slide 36 can engage the locking hook 321 (position E), and / or the locking hook 321 has a leftward offset elastic force, the locking hook 321 will move to the upper left. When it reaches the highest point of the left shoulder of the reciprocating slide 36 (position F), the locking hook 321 can no longer move upward, and the slider 312 can no longer move downward. At this time, release the pressing force. After the pressing force is lost, the slider 312 moves upward under the action of the elastic force. The reciprocating slide 36 will guide the locking hook 321 through the lowest point of the reciprocating slide 36 and slide out. The slider 312 continues to move upward and is eventually fixed by the restraining structure 34 and remains stationary.

[0143] It should be noted that, since the locking hook 321 itself cannot move, the above positions are the relative positions of the locking hook 321 within the slider 312 when it moves downward.

[0144] Of course, the guide surface of the reciprocating slide 36 can also be set to the opposite shape, with the right side higher than the left. In this case, the spring force of the reciprocating slide 36, the locking hook 321, and the shape of the hook 37 are all set to the opposite shape.

[0145] The connector 35 of the self-locking push-button 3 can be installed on the lid 1 and the main body 32 can be installed on the box body 2, or vice versa. When the button 12 is pressed, the self-locking push-button 3 is triggered simultaneously, achieving simultaneous closing and opening. The self-locking push-button 3 design prevents the lid 1 from coming off due to excessive force caused by excessive shaking or inversion, further enhancing the reliability of the insulated box.

[0146] In addition, the self-locking push-button 3 can be like Figure 19 As shown, it is set on the outer periphery, or it can be set as follows: Figure 20 As shown, the self-locking push-button buckle 3 is installed inside the box and can also be used in conjunction with the safety lock buckle 4 to provide multiple layers of safety protection and prevent accidental detachment.

[0161] In this embodiment, as Figure 24 As shown, a handle 17 is provided on the top of the cover 11 or the button 12. The handle 17 allows the user to easily open the lid 1 after pressing, providing a leverage point so that the user can pull open the lid 1 even with one hand. Preferably, the handle 17 is located on the button 12, and the top of the button 12 has a receiving groove 18 for fitting the handle. When the handle 17 is not in use, it can be embedded in the receiving groove 18, maintaining a clean and aesthetically pleasing appearance.

[0162] Example 14

[0163] In this embodiment, as Figure 25 As shown, the lid and body of the box are provided with a hinge device 5, and the lid 1 can be opened from the body 2 around the hinge device 5.

[0164] More preferably, the hinge device 5 is provided with a hinge elastic element 51, which applies a spring force to the lid 1 to separate it from the body 2. The hinge elastic element 51 allows the lid 1 to open automatically without manual intervention after the user releases the restrictions (e.g., pressing button 1 to a non-sealed state, or releasing the self-locking push-button 3, safety lock 4, etc.), making it convenient for the user to use and operate.

[0165] Example 15

[0166] The sealing seat 142 is provided with a buffer layer, which is used to buffer the pressure of the sealing ring 143 contacting the sealing seat 142 and improve the sealing performance.

[0167] Specifically, the buffer layer is configured in the unsealed state in any of the following ways:

[0168] Method 1: The buffer layer is an arc-shaped layer made of elastic material. When the cover 11 is closed, the gap between the cover 11 and the sealing seat 142 gradually decreases or the contact area gradually increases. In this method, when the cover 1 is subjected to external force, it can be compressed a certain distance first, so that the sealing ring 143 gradually contacts the edge of the sealing seat 142. The buffering effect in this process can effectively avoid sudden impact force, making the contact between the sealing ring 143 and the sealing seat 142 smoother and more uniform, thereby improving airtightness and heat preservation effect.

[0169] Method 2: The buffer layer consists of several layers of materials with varying elasticity, forming an arc edge. The elasticity of the buffer layer decreases towards the bottom. When the lid 11 is closed, the gap between the lid 11 and the sealing seat 142 gradually decreases, or the contact area gradually increases. This method gradually distributes the pressure when external force is applied to the lid 1. For example, the top layer uses a softer material, the next layer uses a slightly harder material, and the layer below that can be a more robust structure. Thus, when the lid 1 is closed, the pressure is initially borne by the softer layers, and as the lid is pressed down, it gradually passes through each layer, ultimately achieving maximum buffering effect and preventing sudden impacts.

[0170] Method 3: The buffer layer has a corrugated or pleated transition edge, which ensures that when the cover 11 is closed, the contact force between the cover 11 and the sealing seat 142 is gradually and evenly distributed. This method gives the buffer layer a gradual compressibility. Thus, when the cover 1 is closed, the transition edge can be gradually compressed, forming a gradual buffering process, rather than applying force at the beginning. This greatly reduces pressure concentration and uneven contact, thereby enhancing the user experience and sealing performance.

[0171] Method 4: The buffer layer is a liquid or gel-like substance. This buffer layer ensures that the contact force between the cover 11 and the sealing seat 142 is gradually and evenly distributed when the cover 11 is closed. The liquid or gel-like substance used in this method has high flexibility and pressure absorption capacity. When the cover is closed, the liquid or gel-like substance can deform according to the pressure, providing a more uniform and continuous buffering effect. They can adapt to pressure changes through flow, thus providing more flexible buffering performance than solid materials.

[0172] Method 5: The buffer layer is a transition edge with a honeycomb structure. When the cover 11 is closed, the gap between the cover 11 and the sealing seat 142 gradually decreases or the contact area gradually increases. The unique geometry enhances the buffering effect. The honeycomb structure has good compressibility and resilience, providing very uniform and stable pressure distribution when the cover is pressed down, avoiding damage or seal failure caused by excessive pressure in a single location.
