Description

Technical Field

[0002] The utility model relates to the technical field of electric ovens, and particularly to an electric oven.

Background Art

[0004] In modern household kitchens, electric ovens are common cooking appliances and are widely used for cooking various foods, such as roasted chickens, roasted meats, roasted vegetables, etc. However, traditional electric ovens have some problems during use, such as low cooking efficiency, inconvenient operation, and poor safety.

[0005] Firstly, traditional electric ovens usually have only one chamber and can only cook one type of food at a time, resulting in low cooking efficiency. If multiple foods need to be cooked, they need to be cooked in batches, which is time-consuming and laborious.

Detailed implementation manners

[0053] In order to make the technical problems, technical solutions and beneficial effects solved by this application clearer and more understandable, the following further elaborates on this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0054] This embodiment provides an electric oven, which aims to provide an electric oven with high cooking efficiency, convenient operation and high safety. Figures 1 to 16 An electric oven includes a shell 1 constituting a main structure, and also includes an upper cooking cavity 2 and a lower cooking cavity 3, wherein the upper cooking cavity 2 is located at the upper part of the shell 1, and the lower cooking cavity 3 is located at the lower part of the shell 1. The electric oven also includes an upper door 4 and a lower door 5. The upper door 4 corresponds to the upper cooking cavity 2 and is used to open and close the upper cooking cavity 2. The lower door 5 corresponds to the lower cooking cavity 3 and is movably connected to the shell 1. The lower door 5 is synchronously opened and closed under the drive of the upper door 4, that is, when the upper door 4 is opened, the lower door 5 is also opened at the same time; when the upper door 4 is closed, the lower door 5 is also closed at the same time.

[0055] The electric oven further includes an interlocking mechanism 6, which is used to enable the upper door 4 and the lower door 5 to be opened and closed synchronously when the upper door 4 and the lower door 5 are locked; and to enable the upper door 4 to be opened and closed independently when the lock is released. By setting the interlocking mechanism 6, when it is necessary to open or close the upper door 4 and the lower door 5 at the same time, the synchronous opening and closing of the two can be realized, thereby improving the convenience of operation.

[0056] The electric oven also includes a baking tray 7, which is arranged in the upper cooking cavity 2. The baking tray 7 is used for placing food for cooking.

[0057] The electric oven further includes a locking mechanism 8, which is fixed to the upper door 4 and is in transmission connection with the interlocking mechanism 6. When the upper cooking chamber 2 is used alone, when the upper door 4 and the lower door 5 are unlocked by the interlocking mechanism 6, the locking mechanism 8 locks the baking tray 7 so that it moves synchronously with the upper door 4. By setting the locking mechanism 8, the baking tray 7 can be locked on the upper door 4 when the upper door 4 is opened, so as to prevent the baking tray 7 from accidentally moving or falling, thereby improving the safety of use.

[0058] Furthermore, as a preferred embodiment of the present scheme but not a limitation, a handle 41 is provided on the upper box door 4, and corresponding mounting grooves for mounting the interlocking mechanism 6 and the locking mechanism 8 are provided on the inner side of the upper box door 4, and positioning columns 42 fixedly connected to the lower box door 5 are provided on both sides of the upper box door 4, respectively, and the positioning columns 42 can cooperate with the interlocking mechanism 6 to lock in the horizontal direction, and the interlocking mechanism 6 can cooperate with the lower box door 5 to lock in the vertical direction, thereby realizing the synchronous opening and closing of the upper box door 4 and the lower box door 5, and simultaneously unlocking the locking mechanism 8 and the baking tray 7.

[0059] In this embodiment, a handle 41 is provided on the upper door 4 to facilitate the user to open and close the upper door 4. The inner side of the upper door 4 is provided with corresponding mounting grooves matching the interlocking mechanism 6 and the locking mechanism 8 for fixing and supporting these mechanisms.

[0060] In addition, positioning columns 42 fixedly connected to the lower box door 5 are respectively provided on both sides of the upper box door 4. These positioning columns 42 can cooperate with the interlocking mechanism 6 in the horizontal direction to lock the upper box door 4 and the lower box door 5. The interlocking mechanism 6 itself can also cooperate with the lower box door 5 to achieve locking in the vertical direction. This means that when it is necessary to open and close the upper box door 4 and the lower box door 5 simultaneously, the interlocking mechanism 6 can firmly lock the two box doors together through some of its structural features such as lock catches and buckles to prevent accidental opening. When the two box doors are locked, the locking mechanism 8 will correspondingly unlock from the baking tray 7; when the two box doors are unlocked, the baking tray 7 can be locked with the upper box door 4, and at this time, the user can independently open the upper box door 4 for operations such as placing or taking out food. In this way, the user can flexibly choose whether to open the two box doors simultaneously or independently open the upper box door 4 according to needs, thereby improving the practicability and convenience of the electric oven.

[0061] Further, as a preferred implementation manner rather than a limitation of this solution, the interlocking mechanism 6 includes a horizontal locking member 61 disposed on a corresponding installation groove in the upper box door 4 and capable of moving horizontally along the installation groove for connecting the positioning column 42 to limit the movement of the upper box door 4 along the installation groove in the vertical direction; a vertical locking member 62 disposed on a corresponding installation groove in the upper box door 4 and capable of moving vertically along the installation groove for connecting the lower box door 5 to limit the movement of the upper box door 4 in the horizontal direction, and a first transmission portion 621 for transmitting power and controlling the locking and unlocking states of the locking mechanism 8 is provided on the vertical locking member 62; a first linkage member 63 disposed on a corresponding installation groove in the upper box door 4 for connecting the vertical locking member 62 and the horizontal locking member 61 to make them move synchronously; a power assembly 9 disposed on the handle 41 and capable of driving the horizontal locking member 61 to move horizontally along the installation groove.

[0062] In this embodiment, the horizontal locking member 61 is disposed on a corresponding installation groove in the upper box door 4 and can move horizontally along the installation groove. Its main function is to connect the positioning column 42 to limit the movement of the upper box door 4 along the installation groove in the vertical direction. When the upper box door 4 is closed, the horizontal locking member 61 will cooperate with the positioning column 42 to prevent the upper box door 4 from opening in the vertical direction, thereby realizing the synchronous opening and closing of the upper box door 4 and the lower box door 5.

[0063] The vertical locking member 62 is also disposed on a corresponding installation groove in the upper box door 4 and can move vertically along the installation groove. Its main function is to connect the lower box door 5 to limit the movement of the upper box door 4 in the horizontal direction. A first transmission portion 621 for transmitting power and controlling the locking and unlocking states of the locking mechanism 8 is further provided on the vertical locking member 62.

[0064] The first linkage 63 is arranged on the corresponding installation groove in the upper box door 4 and is used to connect the vertical locking member 62 and the horizontal locking member 61, enabling the two to move synchronously. It can be a connecting rod group, a gear group, etc. Through the action of the first linkage 63, when the horizontal locking member 61 moves, it can drive the vertical locking member 62 to move together, thereby realizing the synchronous opening and closing of the upper box door 4 and the lower box door 5.

[0065] The power assembly 9 is arranged on the handle 41 and is used to drive the horizontal locking member 61 to move horizontally along the installation groove. More specifically, the user can, through a simple operation of the handle, make the horizontal locking member 61 move along the installation groove, thereby realizing the interlocking or unlocking of the upper and lower box doors. During this process, through the action of the first linkage 63, the vertical locking member 62 will also move correspondingly, and the unlocking or locking of the locking mechanism 8 and the baking tray 7 is controlled through the first transmission part 621. Through the cooperation of the horizontal locking member 61, the vertical locking member 62, the first linkage 63 and the power assembly 9, the reliable locking and synchronous opening and closing of the upper box door 4 and the lower box door 5 are realized, and at the same time, the locking and unlocking states of the locking mechanism 8 for the baking tray 7 can be controlled, improving the safety and operation convenience of the electric oven.

[0066] Furthermore, as a preferred implementation manner of this solution rather than a limitation, there are two horizontal locking members 61 which are arranged in an up-and-down stacked and opposite manner, and the horizontal locking members 61 move horizontally in opposite directions along the corresponding installation groove through cooperation with the power assembly 9; the horizontal locking members 61 respectively make the vertical locking member 62 generate vertical movement through the corresponding first linkage 63.

[0067] In this embodiment, the two horizontal locking members 61 can move horizontally in opposite directions along the corresponding installation groove through cooperation with the power assembly 9. Specifically, when the user operates the handle 41, the power assembly 9 will drive the two horizontal locking members 61 to move in opposite directions, thereby releasing the locking of the positioning post 42 and enabling the upper box door 4 to be opened upward.

[0068] At the same time, the two horizontal locking members 61 also respectively cooperate with their corresponding vertical locking members 62 through the corresponding first linkage 63 and make them generate vertical movement. When the horizontal locking member 61 moves, the first linkage 63 will transmit this movement to the vertical locking member 62, causing it to move correspondingly in the vertical direction. Furthermore, the vertical locking member 62 will be in transmission cooperation with the locking mechanism 8 through the first transmission part 621, thereby controlling the unlocking or locking of the locking mechanism 8 and the baking tray 7.

[0069] Further, as a preferred implementation manner rather than a limitation of the present solution, the horizontal locking member 61 includes a first locking end 611 that is cooperatively connected to the access port on the positioning post 42. The first locking end 611 is connected with an extension section 612. In the direction close to the handle 41, the extension section 612 is connected with a power receiving portion 613 that cooperates with the power assembly 9. On the side of the power receiving portion 613 pointing to the power assembly 9, there is a trapezoidal groove. Along one end of the length direction of the power receiving portion 613, there is a spring groove 614 for installing a corresponding first return spring 615. One end of the horizontal locking member 61 is provided with a first transmission member 616 that is connected to the first linkage member 63.

[0070] In this embodiment, the first locking end 611 is a part of the horizontal locking member 61 and is used to cooperatively connect with the access port on the positioning post 42 to achieve the locking of the upper box door 4 in the vertical direction.

[0071] The first locking end 611 is connected with an extension section 612. The extension section 612 extends along the length direction of the horizontal locking member 61 and in the direction close to the handle 41. The main function of the extension section 612 is to provide a connection point for connecting the first locking end 611 and the power receiving portion 613 together.

[0072] In the direction close to the handle 41 of the extension section 612, there is a power receiving portion 613 that cooperates with the power assembly 9. The power receiving portion 613 is used to receive the power from the power assembly 9 and transmit it to the horizontal locking member 61 to drive it to move horizontally.

[0073] On the side of the power receiving portion 613 pointing to the power assembly 9, there is a trapezoidal groove. This trapezoidal groove is used to cooperate with the corresponding structure on the power assembly 9 to achieve the transmission of power and the movement of the horizontal locking member 61. Specifically, the power assembly 9 can push the power receiving portion 613 to move horizontally through the cooperation with the trapezoidal groove, thereby driving the entire horizontal locking member 61 to move laterally.

[0074] Along one end of the length direction of the power receiving portion 613, there is a spring groove 614 for installing a corresponding first return spring 615. The function of the first return spring 615 is to provide a return force so that the horizontal locking member 61 can remain in the original position when there is no external force. When the power assembly 9 drives the horizontal locking member 61 to move, the first return spring 615 will be compressed or stretched and provide a reverse force after the external force disappears to make the horizontal locking member 61 return to the original position.

[0075] One end of the horizontal locking member 61 is also provided with a first transmission member 616 connected to the first linkage member 63, which can be a component corresponding to the specific structure of the first linkage member 63, such as a connecting rod, a rack, a gear, etc. The first transmission member 616 is used to transmit the movement of the horizontal locking member 61 to the first linkage member 63, and further to the vertical locking member 62, so as to achieve the synchronous movement of the vertical locking member 62. Through the connection of the first transmission member 616, the movement of the horizontal locking member 61 can be converted into the movement of the vertical locking member 62.

[0076] Furthermore, as a preferred embodiment of the present invention but not a limitation, the vertical locking member 62 includes a first transmission part 621 whose upper end is cooperatively connected to the first linkage member 63, and a second locking end 622 whose lower end can be inserted into the corresponding receiving hole on the lower box door 5, and a second transmission part 623 cooperatively connected to the locking mechanism 8 is also provided between the second locking end 622 and the first transmission part 621.

[0077] In this embodiment, the first transmission part 621 and the second transmission part 623 can be racks, gears, connecting rods and other components respectively; the second locking end 622 is used to cooperate with the corresponding structure on the lower door 5, such as a receiving hole, a slot, etc., to achieve the locking of the lower door 5 in the vertical direction. Specifically, when the vertical locking member 62 receives the movement transmitted by the first transmission part 621, the second locking end 622 will move accordingly and insert or disengage from the receiving hole on the lower door 5, thereby achieving the locking or unlocking of the lower door 5. At the same time, the movement change of the vertical locking member 62 can transmit this movement to the locking mechanism 8 through the second transmission part 623, thereby controlling the locking or unlocking state of the locking mechanism 8 and the baking tray 7.

[0078] Further, as a preferred embodiment of the present invention but not limiting, the locking mechanism 8 includes a second linkage member 81 that is transmission-connected to the second transmission member 623, the second linkage member 81 is transmission-connected to a locking member 82, the locking member 82 includes a third transmission member 821 that is transmission-connected to the second linkage member 81 at one end and a locking member 822 that is arranged at the other end, the locking member 822 is connected to a locking base 823 that is fixed to the inner side of the upper box door and is used to lock the baking tray 7, and one side of the locking base 823 is provided with a locking member that can cooperate with the locking member 822. A plug hole 824, a plug groove 825 which can be connected to the baking tray 7 is provided on the side of the locking base 823 facing the upper cooking cavity 2, and a plug connector 71 which can be connected to the plug groove 825 is fixedly connected to the baking tray 7, and a connecting notch 711 is provided at the side end of the plug connector 71. When the plug connector 71 is inserted into the plug groove 825, the connecting notch 711 can cooperate with the locking portion 822 to lock the baking tray 7; an elastic sheet 826 which can abut against the plug connector 71 to enhance the locking effect is provided in the plug groove 825.

[0079] In this embodiment, the second linkage 81 may correspond to the specific structure of the second transmission part 623 and adopt a connecting rod group, a gear group, etc., so as to receive the motion from the second transmission part 623 and at the same time transmit the received motion to the locking member 82.

[0080] The locking member 82 includes a third transmission part 821 whose one end is in transmission connection with the second linkage 81, and a locking part 822 provided at the other end. The third transmission part 821 is used to transmit the motion of the second linkage 81 to the locking part 822, and structures such as a connecting rod, a rack, a gear, etc. can be adopted. The locking part 822 is used to cooperate with the plug-in part 71 on the baking tray 7 to realize the locking or unlocking of the baking tray 7.

[0081] The locking base 823 is used to provide a fixed point, so that the locking part 822 can stably cooperate with the plug-in part 71 on the baking tray 7 to realize the locking of the baking tray 7. A plug-in hole 824 that can cooperate with the locking part 822 is provided on one side thereof. The plug-in hole 824 is used to accommodate the locking part 822 and provide a mating surface, so that the locking part 822 can stably cooperate with the plug-in part 71 on the baking tray 7. Similarly, the plug-in slot 825 also provides a mating surface for the plug-in part 71, so that the plug-in part 71 can be stably connected to the locking base 823.

[0082] A plug-in part 71 that can be connected in cooperation with the plug-in slot 825 is fixedly connected to the baking tray 7. The plug-in part 71 is used to cooperate with the plug-in slot 825 on the locking base 823 to realize the locking of the baking tray 7 with the upper door.

[0083] A connection notch 711 is provided at the side end of the plug-in part 71. When the plug-in part 71 is inserted into the plug-in slot 825, the connection notch 711 can cooperate with the locking part 822 to lock the baking tray 7. The connection notch 711 is used to cooperate with the locking part 822 to realize the locking of the baking tray 7. When the plug-in part 71 is inserted into the plug-in slot 825, the locking part 822 can cooperate with the plug-in part 71 through the connection notch 711, thereby realizing the locking of the baking tray 7.

[0084] An elastic piece 826 that can abut against the plug-in part 71 to enhance the locking effect is provided in the plug-in slot 825. The elastic piece 826 is used to increase the friction between the plug-in part 71 and the plug-in slot 825, thereby enhancing the locking effect. When the plug-in part 71 is inserted into the plug-in slot 825, the elastic piece 826 will abut against the plug-in part 71, thereby increasing the friction between the two, so that the baking tray 7 can be more stably fixed on the upper door.

[0085] Further, as a preferred implementation manner rather than a limitation of this solution, a guiding base 43 for guiding the movement and resetting of the horizontal locking member 61 is installed inside the upper box door 4. The guiding base 43 includes a corresponding first guiding groove 431 sleeving the power receiving portion 613. At two ends of the guiding base 43 along the direction of the first guiding groove 431, first limiting portions 432 capable of abutting against the first reset spring 615 are respectively provided.

[0086] In this embodiment, by installing the guiding base 43 inside the upper box door 4 and setting the corresponding first guiding groove 431 and first limiting portions 432, the guiding of the movement and resetting of the horizontal locking member 61 are realized. The stability and accuracy of the movement of the horizontal locking member 61 are improved, and it is ensured that it can be accurately reset when there is no external force influence.

[0087] Further, as a preferred implementation manner rather than a limitation of this solution, the power assembly 9 includes an embedding member 91 perpendicular to the guiding base 43. The embedding member 91 includes an upper embedding portion 911 and a lower embedding portion 912 respectively inserted into corresponding embedding holes at the upper and lower ends of the guiding base 43. A connecting rod 913 located inside the guiding base 43 is provided between the upper embedding portion 911 and the lower embedding portion 912. The connecting rod 913 abuts against an inclined surface on a trapezoidal groove of the power receiving portion 613 to enable the power receiving portion 613 to move horizontally along a direction perpendicular to the connecting rod 913. A second reset spring 914 is fixedly provided between the outer wall of the embedding member 91 and the guiding base 43. The embedding member 91 abuts against a power rod 92 perpendicular to it. The power rod 92 passes through the handle 41. A limiting rod 921 capable of being clamped with the handle 41 is provided at one end of the power rod 92 close to the embedding member 91.

[0088] In this embodiment, when the user operates through the handle 41, the power rod 92 drives the embedding member 91 to move, thereby driving the power receiving portion 613 to move through the connecting rod 913, realizing the movement of the horizontal locking member 61, and further locking or unlocking the upper and lower box doors, improving the operation convenience and reliability of the electric oven.

[0089] Further, as a preferred implementation manner rather than a limitation of this solution, the handle 41 includes a mounting seat 411 fixedly connected to the guiding base 43, and a connecting pipe 412 arranged in a direction away from the mounting seat 411. A grip 413 is connected to the lower end of the connecting pipe 412. A first installation cavity 414 is provided in the connecting pipe 412, which can fit the insert 91 and can be clamped with the limiting rod 921. The power rod 92 passes through the first installation cavity 414 and is also provided with a second installation cavity 415. The tail end of the power rod 92 passes through the second installation cavity 415 and is fixedly connected with a corresponding control button 922 that can rotate along the inner wall of the second installation cavity 415. A corresponding third return spring 923 is sleeved on the power rod 92, and the third return spring 923 abuts against the control button 922 and the cavity wall of the second installation cavity 415 respectively.

[0090] In this embodiment, the first installation cavity 414 is used to accommodate the insert 91 and provide a fitting surface so that the insert 91 can be stably fitted in the connecting pipe 412. At the same time, the first installation cavity 414 is also used to accommodate the limiting rod 921 and provide a clamping surface so that the limiting rod 921 can be stably clamped with the connecting pipe 412.

[0091] The second installation cavity 415 is used to accommodate the tail end of the power rod 92 and provide an installation space so that the tail end of the power rod 92 can be stably installed in the connecting pipe 412.

[0092] The control button 922 is used to control the movement of the power rod 92 and control the movement of the insert 91 through the power rod 92, so as to realize the movement of the horizontal locking member 61.

[0093] The third return spring 923 is used to provide a return force when the control button 922 is not working, so that the control button 922 is kept in the original position, and thus the insert 91 is kept in the corresponding position through the power rod 92.

[0094] Further, as a preferred implementation manner of this solution rather than a limitation, a connection hole 416 for the power rod 92 to pass through is provided between the first installation cavity 414 and the second installation cavity 415. At one end in the first installation cavity 414, a pair of first limiting plates 417 adapted to the limiting rod 921 are symmetrically provided around the connection hole 416, aiming to stabilize the position of the power rod 92 in the first installation cavity 414. It should be emphasized that when the limiting rod 921 is engaged with the first limiting plate 417, the upper and lower box doors are in an interlocked state and the synchronous switch will be triggered. At the upper ends of the two first limiting plates 417, second limiting plates 418 perpendicular to them and connected to the inner wall of the first installation cavity 414 are respectively provided. The two second limiting plates 418 are parallel to each other and the parallel spacing matches the rod diameter of the power rod 92. When the power rod 92 moves towards the upper box door 4 to the upper end of the first limiting plate 417, the control knob 922 can be rotated to make the limiting rod 921 engage with the second limiting plate 418. At this time, the upper and lower box doors are in an unlocked state, and the upper box door can be independently opened and closed, and can lock and move together with the baking tray 7.

[0095] Further, as a preferred implementation manner of this solution rather than a limitation, at one end in the second installation cavity 415, a second guiding groove 419 adapted to the power rod 92 is provided around the connection hole 416. A third return spring 923 abuts against the end wall of the second installation cavity 415. A plurality of structural plates 420 connected to the inner wall of the second installation cavity 415 are uniformly provided along the outer periphery of the second guiding groove 419.

[0096] In this embodiment, by adding the second guiding groove 419 and providing a plurality of structural plates 420, the guiding and supporting of the power rod 92 are realized, and the stability and accuracy of its movement are improved. At the same time, through the setting of the third return spring 923, the automatic reset of the control knob 922 is realized, and the operation convenience of the electric oven is improved.

[0097] Further, as a preferred implementation manner of this solution rather than a limitation, an anti - detachment plate 44 for preventing the horizontal locking member 61 and the vertical locking member 62 from detaching from their respective installation grooves is fixedly provided inside the upper box door 4.

[0098] In this embodiment, the anti - detachment plate 44 cooperates with the installation grooves of the horizontal locking member 61 and the vertical locking member 62, playing a role of blocking, limiting and guiding the movement path. It can improve the reliability, safety of the electric oven and the operation accuracy of locking the upper and lower box doors, and avoid failures or safety hazards caused by the accidental detachment of the horizontal locking member 61 and the vertical locking member 62 from their respective installation grooves.

[0099] Working principle of the present utility model:

[0100] The present utility model provides an electric oven with efficient cooking, convenient operation and safe use, which includes a housing, an upper cooking cavity, a lower cooking cavity, an upper door, a lower door, an interlocking mechanism, a baking tray and a locking mechanism. The upper cooking cavity and the lower cooking cavity are respectively located in the upper and lower parts of the housing, and the upper door and the lower door are respectively used to open and close the upper cooking cavity and the lower cooking cavity. The interlocking mechanism is used to lock the upper door and the lower door so that they are opened and closed synchronously, improving the operation convenience. The locking mechanism is used to lock the baking tray so that it moves synchronously with the upper door, improving the safety of use.

[0101] Specifically, a handle is provided on the upper door for the user to open and close conveniently. The interlocking mechanism and the locking mechanism are installed on the inner side of the upper door. Positioning columns are provided on both sides of the upper door for fixedly connecting with the lower door and cooperating with the interlocking mechanism for horizontal locking. The interlocking mechanism includes a horizontal locking member and a vertical locking member for connecting the upper door and the lower door to achieve synchronous opening and closing. The locking mechanism includes a second linkage member and a locking member for locking the baking tray.

[0102] When the user only uses the upper cooking cavity, the control button on the handle can be pressed to push the power rod. Under the pressing action of the power rod, the insert moves towards the electric oven. The connecting rod provided on the insert abuts against the inclined surface on the trapezoidal groove of the power receiving part, so that the two horizontal locking members move horizontally towards the middle. At the same time, under the action of the linkage member, the vertical locking members on both sides move vertically synchronously. Finally, the horizontal locking member is unlocked from the positioning column, the vertical locking member is unlocked from the lower door, and the upper door and the lower door are completely unlocked from the interlocking state. At this time, by rotating the control button, the limiting rod provided on the power rod is engaged with the second limiting plate to maintain the non-interlocking state. At this time, the upper door can be opened and closed independently. At the same time, the second linkage member of the locking mechanism will also receive the movement of the vertical locking member and then lock the baking tray so that it moves synchronously with the upper door, ensuring that the baking tray will not move or fall accidentally during use and improving the safety of use. When the user needs to use the lower cooking cavity, the control button is rotated to the initial position. The power rod rebounds under the action of the third return spring. The limiting rod is finally engaged with the first limiting plate. Then the two horizontal locking members move towards both sides respectively under the action of the first return spring and lock with the positioning column. The vertical locking member moves downward under the action of the linkage member and locks with the lower door. The upper and lower doors are interlocked. At this time, only the handle of the upper door can be used to open and close the upper and lower two doors simultaneously.

Any structure similar to the method structure of this application, or any technical deduction or replacement made under the premise of the concept of this application, should be regarded as the protection scope of this application.
