Description

Technical Field

[0001] The present application relates to the technical field of production and processing equipment for tungsten-based powder products, and particularly relates to a boat transfer device and a redox furnace system. Background Art

[0002] Existing redox furnace systems for producing tungsten-based powder products generally include a redox furnace and a boat transfer mechanism. The redox furnace includes multiple rows of furnace tubes, and the furnace tubes in different rows are sequentially distributed vertically. Each row of furnace tubes includes a plurality of furnace tubes arranged horizontally. The horizontal direction can be one of the dimensions in the horizontal direction, and the vertical direction can be the direction perpendicular to the horizontal direction.

[0003] Such as Figure 1 and Figure 2 As shown, each furnace tube 110 includes a corresponding furnace door 120 and a door opening mechanism 130. The furnace door 120 is generally divided into a boat inlet furnace door 120a and a boat outlet furnace door 120b. The door opening mechanism 130 corresponding to the boat inlet furnace door 120a is called a boat inlet door opening mechanism 130a, and the door opening mechanism 130 corresponding to the boat outlet furnace door 120b is called a boat outlet door opening mechanism 130b.

[0004] Such as Figure 1 As shown, the boat inlet door opening mechanism 130a generally includes a cam tongue pressing mechanism 131a, a first lever fulcrum 132a, a first door opening lever 133a, and a first return spring 134a. The first lever fulcrum 132a is arranged on the outer wall of the furnace tube 110. The first door opening lever 133a is rotatably supported on the first lever fulcrum 132a, and the first end of the first door opening lever 133a extends towards the cam tongue pressing mechanism 131a, and the second end of the first door opening lever 133a is connected to the boat inlet furnace door 120a. The first end of the first return spring 134a is connected to the second end of the first door opening lever 133a, and the second end of the first return spring 134a is connected to the furnace tube 110.

[0005] Such as Figure 1 As shown, in the boat inlet door opening mechanism 130a and the corresponding boat inlet furnace door 120a, when the cam tongue pressing mechanism 131a presses the first end of the first door opening lever 133a, the second end of the first door opening lever 133a drives the boat inlet furnace door 120a to open the furnace tube 110 and stretches the first return spring 134a. When the cam tongue pressing mechanism 131a releases the first end of the first door opening lever 133a, the first return spring 134a resets and drives the second end of the first door opening lever 133a to reset, so that the boat inlet furnace door 120a covers the furnace tube 110 again.

[0006] Such as Figure 2As shown, the boat-out door opening mechanism 130b generally includes an opening cylinder 131b, a second lever fulcrum 132b, a second opening lever 133b, and a second return spring 134b. The first end of the opening cylinder 131b is rotatably connected to the furnace tube 110, and the second lever fulcrum is provided on the outer wall of the furnace tube. The second opening lever is rotatably supported by the second lever fulcrum, and the first end of the second opening lever 133b is rotatably connected to the second end of the opening cylinder 131b. The second end of the second opening lever 133b is connected to the boat-out furnace door 120b. The first end of the second return spring 134b is connected to the second end of the second opening lever 133b, and the second end of the second return spring 134b is connected to the furnace tube 110.

[0007] As Figure 2 shown, in the boat-out door opening mechanism 130b and the corresponding boat-out furnace door 120b, when the opening cylinder 131b drives the first end of the second opening lever 133b to rotate, the second end of the second opening lever 133b drives the boat-out furnace door 120b to open the furnace tube 110, and the second return spring 134b is stretched. When the opening cylinder 131b releases the first end of the second opening lever 133b, the second return spring 134b resets and drives the second end of the second opening lever 133b to reset, so that the boat-out furnace door 120b covers the furnace tube 110 again.

[0008] Common existing boat transfer mechanisms are divided into a boat feeding mechanism and a boat taking mechanism. The boat feeding mechanism is a boat transfer mechanism for feeding a boat, that is, moving a boat into the furnace tube, and the boat taking mechanism is a boat transfer mechanism for taking a boat, that is, moving a boat out of the furnace tube.

[0009] Generally, in combination with Figure 2 referring to Figure 3 shown, after all the boat-in furnace doors 120b in a whole row are opened, multiple groups of boat feeding mechanisms 140 push multiple rows of boats (not shown in the figure) placed with materials into multiple rows of furnace tubes 110 in the redox furnace.

[0010] In combination with Figure 2 referring to Figure 3 shown, each group of boat feeding mechanisms 140 includes a boat pushing motor 141, a chain drive mechanism 142, and multiple boat pushing rods 143 arranged in a row and corresponding to multiple furnace tubes 110 in a row one by one. Among them, the boat pushing motor 141 drives multiple boat pushing rods 143 in a row through the sprocket drive mechanism 142 to push multiple boats placed with materials in a row into the corresponding row of furnace tubes 110.

[0011] Thus, in order to realize boat feeding or boat taking for each row of furnace tubes 110 in the redox furnace, the number of rows of furnace tubes 110 in the redox furnace needs to correspond one by one to the number of groups of boat transfer mechanisms for boat feeding or boat taking. For example, if the furnace tubes 110 in the redox furnace have two rows, then the number of groups of boat feeding mechanisms 140 or boat taking mechanisms (not shown in the figure) also needs to be two groups.

[0012] It can be seen from this that in combination with Figure 1 and Figure 2 , referring to Figure 3 as shown, in order to realize sending boats into or taking boats out of the furnace tubes 110 in each row of the redox furnace, it is necessary to send or take boats corresponding to a whole row of furnace tubes 110. In this way, it is necessary to open the boat inlet furnace door 120a or the boat outlet furnace door 120b of the whole row of furnace tubes 110 at the same time. When the boat inlet furnace door 120a or the boat outlet furnace door 120b of a whole row of furnace tubes 110 is opened simultaneously, a large amount of process gas will escape, which is likely to cause a fire and has a great potential safety hazard.

[0013] Therefore, how to reduce the potential safety hazard in the process of sending and taking boats during the production of tungsten-based powder products is a technical problem that those skilled in the art urgently need to solve. Utility Model Content

[0014] In view of this, in order to solve the above technical problems, the present application provides a boat transfer device and a redox furnace system.

[0019] And a boat transfer mechanism, arranged on the main body mounting frame, for moving the boat between the boat temporary storage cavity and the furnace tube;

[0020] Among them, the transverse movement mechanism is used to drive the main body mounting frame to move horizontally, so that the boat temporary storage cavity switches to align with different furnace tubes in the same row, and the lifting mechanism is used to drive the main body mounting frame to move vertically, so that the boat temporary storage cavity switches to align with furnace tubes in different rows.

[0021] In order to solve the above technical problems, another technical solution adopted by the present application is to provide a redox furnace system, which includes:

[0022] A redox furnace, including multiple rows of furnace tubes, and the furnace tubes in different rows are arranged vertically in sequence; each row of furnace tubes includes a plurality of furnace tubes arranged horizontally;

[0023] A first boat transfer device, which is the above-mentioned boat transfer device, arranged on the boat inlet side of the redox furnace, for moving the boat from the boat temporary storage cavity of the first boat transfer device into the furnace tube;

[0024] And a second boat transfer device, which is the above-mentioned boat transfer device, is arranged on the boat outlet side of the redox furnace and is used to move the boat from the furnace tube into the boat temporary storage cavity of the second boat transfer device.

[0025] Optionally, in the first boat transfer device, the boat transfer mechanism is a boat feeding mechanism, and the boat connecting part of the boat feeding mechanism is a boat pushing push rod. When the boat pushing push rod extends out of the boat temporary storage cavity, the boat pushing push rod is used to push the boat in the boat temporary storage cavity into the furnace tube;

[0026] Among them, the first boat transfer device includes a plurality of first rollers, and the plurality of first rollers are rotatably arranged at the bottom of the boat temporary storage cavity and are used to rollingly contact the boat when the boat enters and exits the boat temporary storage cavity.

[0027] Optionally, in the second boat transfer device, the boat transfer mechanism is a boat picking mechanism, and the boat connecting part of the boat picking mechanism is a boat hooking component; when the boat hooking component retracts into the boat temporary storage cavity, the boat hooking component will bring back the hooked boat to the boat temporary storage cavity;

[0028] The second boat transfer device includes a boat receiving door and a boat receiving door driving part; the boat receiving door is movably arranged on the main body mounting frame, and the boat receiving door driving part is arranged on the main body mounting frame and is connected to the boat receiving door; wherein, the boat receiving door driving part is used to drive the boat receiving door to move so that the boat receiving door covers or opens the boat temporary storage cavity.

[0029] Optionally, in the second boat transfer device, the boat picking mechanism further includes:

[0030] A boat receiving cylinder, which is arranged on the main body mounting frame;

[0031] A boat receiving moving frame, which is connected to the boat receiving cylinder;

[0032] And a second roller, which is rotatably arranged on the boat receiving moving frame;

[0033] Among them, the boat receiving cylinder is used to drive the boat receiving moving frame to move longitudinally so that the boat receiving moving frame extends out of or retracts into the boat temporary storage cavity; when the boat receiving moving frame retracts towards the boat temporary storage cavity, the boat receiving moving frame can support the boat hooked by the boat hooking component; the second roller is used to rollingly contact the boat when the boat moves to or out of the boat receiving moving frame.

[0034] Optionally, in the second boat transfer device, the boat hooking component includes:

[0038] Among them, the claw driving part is used to drive the claw of the boat hook to move, so as to hook or release the boat dish.

[0039] Beneficial effects: Different from the prior art, in this application, by cooperating the transverse movement mechanism with the lifting mechanism, the boat dish temporary storage cavity can be aligned with different furnace tubes at different times. When the boat dish temporary storage cavity is aligned with the furnace tube each time, the boat dish transfer device can move the boat dish into or out of the furnace tube. In this way, there are at least the following beneficial effects in the first aspect and the second aspect.

[0040] In the first aspect, the same boat dish transfer mechanism can be used to send boats into multiple furnace tubes of the redox furnace, or the same boat dish transfer mechanism can be used to take boats out of multiple furnace tubes of the redox furnace. In this way, the overall volume of the redox furnace system can be reduced, and the investment and use cost of the redox furnace system can be reduced.

[0041] In the second aspect, each time the same boat dish transfer mechanism sends or takes a boat, only the furnace door of one furnace tube needs to be opened separately to send or take a boat to one furnace tube separately. Through multiple times of sending or taking boats, the boats are sent or taken to multiple furnace tubes in sequence. In this way, the number of furnace doors that need to be opened each time when sending or taking a boat can be reduced, and thus the leakage of process gas can be reduced, thereby reducing the probability of fire occurrence and reducing the safety hazards in the process of sending and taking boats.

[0075] Second explanation: The horizontal X, the vertical Y, and the vertical Z are not coplanar, and any two of the horizontal X, the vertical Y, and the vertical Z are not parallel.

[0076] Third explanation: If "sending the boat" is not specified where to send in the following text, it all means sending the boat into the furnace tube 11 of the redox furnace 10; if "taking the boat" is not specified where to take in the following text, it all means taking the boat from the furnace tube 11 of the redox furnace 10.

[0077] Embodiment 1

[0078] Please refer to Figures 4 - 9 , the redox furnace system 1 of the present application includes a redox furnace 10 and a boat transfer device 20.

[0079] The redox furnace 10 includes multiple rows of furnace tubes 11, and the furnace tubes 11 in different rows are sequentially distributed along the vertical direction Z; each row of furnace tubes 11 includes multiple furnace tubes 11 arranged along the horizontal direction X, and each furnace tube 11 extends along the longitudinal direction Y. The boat transfer device 20 is used to move a boat (not shown in the figure) into or out of the furnace tubes 11.

[0080] The boat transfer device 20 may include a lateral movement mechanism 21, a lifting mechanism 22, a main body mounting frame 23, and a boat transfer mechanism 24.

[0081] The lifting mechanism 22 is arranged on the lateral movement mechanism 21. The main body mounting frame 23 is arranged on the lifting mechanism 22. The main body mounting frame 23 is provided with a boat temporary storage cavity 231 for accommodating a boat. The boat transfer mechanism 24 is arranged on the main body mounting frame 23 and is used to move the boat between the boat temporary storage cavity 231 and the furnace tubes 11.

[0082] Among them, the lateral movement mechanism 21 is used to drive the main body mounting frame 23 to move horizontally in the X direction so that the boat temporary storage cavity 231 switches to align with different furnace tubes 11 in the same row, and the lifting mechanism 22 is used to drive the main body mounting frame 23 to move vertically in the Z direction so that the boat temporary storage cavity 231 switches to align with furnace tubes 11 in different rows.

[0083] In the above manner, by cooperating the lateral movement mechanism 21 and the lifting mechanism 22, the boat temporary storage cavity 231 can be aligned with different furnace tubes 11 at different times. Each time the boat temporary storage cavity 231 aligns with a furnace tube 11, the boat can be moved into or out of the furnace tube 11 through the boat transfer device 20. In this way, there are at least the following beneficial effects in the first aspect and the second aspect.

[0084] In the first aspect, the same boat transfer mechanism 24 can be used to send boats into multiple furnace tubes 11 of the redox furnace 10, or the same boat transfer mechanism 24 can be used to take boats out of multiple furnace tubes 11 of the redox furnace 10. In this way, the overall volume of the redox furnace system 1 can be reduced, and the investment and use cost of the redox furnace system 1 can be reduced.

[0085] In the second aspect, each time the same boat transfer mechanism 24 sends or takes a boat, only the furnace door 15 of one furnace tube 11 needs to be opened separately to send or take a boat for one furnace tube 11 alone. By sending or taking boats multiple times in sequence, the sending or taking of boats for multiple furnace tubes 11 can be completed. In this way, the number of furnace doors 15 that need to be opened each time when sending or taking a boat can be reduced, and thus the leakage of process gas can be reduced, thereby reducing the probability of fire and reducing the safety hazards during the process of sending and taking boats.

[0086] Optionally, in combination with Figure 6 、 Figure 10 and Figure 12 , refer to Figure 8 and Figure 9 , the boat transfer device 20 includes a photoelectric switch 25, and the photoelectric switch 25 is arranged on the main body mounting frame 23 and is used to cooperate with the mirror 12 to detect whether the boat temporary storage cavity 231 is aligned with the furnace tube 11. The mirror 12 is relatively fixed in position with respect to the furnace tube 11.

[0087] It should be noted that each furnace tube 11 of the redox furnace 10 is correspondingly provided with a mirror 12. When the boat temporary storage cavity 231 is aligned with the furnace tube 11, the photoelectric switch 25 is aligned with the mirror 12 corresponding to the furnace tube 11. At this time, the photoelectric switch 25 can detect the optical signal reflected by the mirror 12. Thus, when the photoelectric switch 25 detects the reflected optical signal, it can be determined that the boat temporary storage cavity 231 is aligned with the furnace tube 11.

[0088] Optionally, in combination with Figure 6 refer to Figures 7 - 9 , the boat transfer mechanism 24 includes a boat displacement assembly 241 and a boat connecting member 242.

[0089] The boat displacement assembly 241 is arranged on the main body mounting frame 23. The boat connecting member 242 is movably arranged in the boat temporary storage cavity 231 and is connected to the boat displacement assembly 241, and is used to connect the boat in a detachable manner.

[0090] Among them, the boat displacement assembly 241 is used to drive the boat connecting member 242 to move along the longitudinal direction Y, so that the boat connecting member 242 extends out of or retracts into the boat temporary storage cavity 231 to drive the boat to move between the boat temporary storage cavity 231 and the furnace tube 11.

[0091] It should be noted that the detachable connection means that the boat connecting member 242 can switch between a first state and a second state. The first state is the state where the boat connecting member 242 is connected to the boat and can move together. The second state is the state where the boat connecting member 242 releases the connection with the boat and can move independently relative to the boat. In this way, when the boat connecting member 242 extends out of or retracts into the boat temporary storage cavity 231, the boat connecting member 242 can drive the boat to move together in the first state and move independently of the boat in the second state.

[0092] Optionally, in combination with Figure 6 refer to Figures 7 - 9, the boat dish shifting assembly 241 includes a boat shifting drive member 2411 and a first chain conveyor mechanism 2412. The boat shifting drive member 2411 is disposed on the main body mounting bracket 23, and the first chain conveyor mechanism 2412 is disposed on the main body mounting bracket 23 and connected to the boat shifting drive member 2411. Among them, the boat shifting drive member 2411 is used to drive the first chain conveyor mechanism 2412 to drive the boat dish connecting member 242 to move along the longitudinal direction Y.

[0093] By way of example and not limitation, in combination with Figure 6 , Figure 10 and Figure 11 , refer to Figures 7 - 9 , the boat shifting drive member 2411 may include a first servo motor 210 and a first speed reduction mechanism (not shown in the figure), a first worm gear (not shown in the figure) and a first worm (not shown in the figure). The first chain conveyor mechanism 2412 includes a first rotating shaft 310, a first sprocket 320, a second sprocket 330 and a first drive chain 340. The first rotating shaft 310 is rotatably disposed on the main body mounting bracket 23, and the first sprocket 320 and the first worm are respectively disposed on the first rotating shaft 310. The second sprocket 330 is rotatably disposed on the main body mounting bracket 23 and is spaced from the first rotating shaft 310 along the longitudinal direction Y. The first worm gear meshes with the first worm. The first drive chain 340 is respectively wound around the first sprocket 320 and the second sprocket 330, and the boat dish connecting member 242 is connected to the first drive chain 340.

[0094] In the above manner, the meshing of the first worm gear and the first worm can form a first speed reduction mechanism. Among them, the first angular velocity and the first torque of the first worm gear are converted into the second angular velocity and the second torque of the first worm. Among them, the second angular velocity is less than the first angular velocity, and the second torque is greater than the first torque. In this way, the first rotating shaft 310 can be driven to rotate more labor - savingly.

[0095] Optionally, in combination with Figure 6 refer to Figure 7 as shown, the boat dish shifting assembly 241 includes a first moving seat 2413 and a first linear slide rail 2414. The first linear slide rail 2414 is fixed to the main body mounting bracket 23. The first moving seat 2413 is slidably engaged with the first linear slide rail 2414 along the longitudinal direction Y, and the boat dish connecting member 242 is fixed to the first moving seat 2413. When the boat dish connecting member 242 extends or retracts from the main body mounting bracket 23 along the longitudinal direction Y, the first moving seat 2413 moves relative to the first linear slide rail 2414 along the longitudinal direction Y.

[0096] Optionally, in combination with Figure 10 , Figure 12 and Figure 6 , refer to Figures 7 - 9 as shown, the boat dish transfer device 20 includes a door opening mechanism 26. The door opening mechanism 26 includes a door opening drive assembly 261 and a door opening push rod 262.

[0097] The door opening drive assembly 261 is disposed on the main body mounting bracket 23. The door opening push rod 262 is movably disposed on the main body mounting bracket 23 and connected to the door opening drive assembly 261. Among them, the door opening drive assembly 261 is used to drive the door opening push rod 262 to move along the longitudinal direction Y, so that the door opening push rod 262 extends out of or retracts into the main body mounting bracket 23. When the door opening push rod 262 extends out of the main body mounting bracket 23, the door opening push rod 262 is used to abut against the door opening lever 13 on the redox furnace 10 to open the furnace door 15 of the furnace tube 11.

[0098] In the above manner, when the door opening push rod 262 extends out of the main body mounting bracket 23, the door opening push rod 262 can abut against the door opening lever 13 on the furnace tube 11 aligned with the current boat storage cavity 231 to open the furnace door 15 of the furnace tube 11 aligned with the current boat storage cavity 231. When the door opening push rod 262 retracts into the main body mounting bracket 23, the door opening push rod 262 can disengage from the door opening lever 13, and the door opening lever 13 is reset under the drive of the return spring 14, so that the furnace door 15 of the furnace tube 11 aligned with the current boat storage cavity 231 is closed again.

[0099] It should be noted that each furnace door 15 of the furnace tube 11 has a corresponding door opening lever 13 and a return spring 14. The door opening lever 13 is rotatably disposed on the corresponding furnace tube 11 and has a first end and a second end. The first end of the door opening lever 13 is used to abut against the door opening push rod 262, and the second end of the door opening lever 13 is connected to the corresponding furnace door 15. The first end of the return spring 14 is connected to the second end of the door opening lever 13, and the second end of the return spring 14 is connected to the furnace tube 11.

[0100] Among them, when the door opening push rod 262 extends out of the main body mounting bracket 23, the door opening lever 13 abuts against the first end of the door opening lever 13, and the second end of the door opening lever 13 drives the furnace door 15 to open the furnace tube 11. When the door opening lever 13 releases the second end of the door opening lever 13, the return spring 14 is reset to drive the door opening lever 13 to reset, so that the furnace door 15 covers the furnace tube 11 again.

[0101] Optionally, in combination with Figure 10 and Figure 6 , referring to 11 and Figures 7 - 9 , the door opening drive assembly 261 includes an electric drive member 2611, a manual drive member 2612, and a second chain conveyor mechanism 2613.

[0102] The electric drive member 2611 is disposed on the main body mounting bracket 23. The manual drive member 2612 is disposed on the main body mounting bracket 23. The second chain conveyor mechanism 2613 is disposed on the main body mounting bracket 23, and the second chain conveyor mechanism 2613 is connected to the electric drive member 2611 and the manual drive member 2612 separately or simultaneously.

[0103] Among them, the door-opening push rod 262 is connected to the second chain conveyor mechanism 2613. The electric drive member 2611 and the manual drive member 2612 can drive the second chain conveyor mechanism 2613 in an alternative use manner to drive the door-opening push rod 262 to move along the longitudinal direction Y, so that the door-opening push rod 262 extends or retracts along the longitudinal direction Y from the main body mounting frame 23.

[0104] In the above manner, when the electric drive member 2611 can operate normally, the second chain conveyor mechanism 2613 can be driven by the electric drive member 2611. When the electric drive member 2611 cannot operate normally, the second chain conveyor mechanism 2613 can be driven by the manual drive member 2612.

[0105] It should be noted that the electric drive member 2611 converts electrical energy into the kinetic energy of the second chain conveyor mechanism 2613. The manual drive member 2612 converts the kinetic energy of the human body into the kinetic energy of the second chain conveyor mechanism 2613.

[0106] For example rather than idly, in combination with Figure 10 and Figure 6 , refer to 11 and Figures 7 - 9 , the electric drive member 2611 includes a second servo motor (not labeled in the figure), a second worm gear (not shown in the figure), and a second worm (not shown in the figure). The manual drive member 2612 includes a door-opening handwheel (not labeled in the figure), a third worm gear (not shown in the figure), and a third worm (not shown in the figure). The second chain conveyor mechanism 2613 includes a second rotating shaft 410, a third sprocket (not shown in the figure), a fourth sprocket (not shown in the figure), and a second transmission chain 440. The second rotating shaft 410 is rotatably arranged on the main body mounting frame 23. The third sprocket, the second worm, and the third worm are respectively arranged on the second rotating shaft 410. The fourth sprocket is rotatably arranged on the main body mounting frame 23 and is spaced from the second rotating shaft 410 along the longitudinal direction Y. The second worm gear meshes with the second worm. The third worm gear meshes with the third worm. The second transmission chain 440 is respectively wound around the third sprocket and the fourth sprocket. The door-opening push rod 262 is connected to the second transmission chain 440.

[0107] In the above manner, it has at least the following beneficial effects in the first aspect and the third aspect.

[0108] In the first aspect, the first driving mode or the second driving mode can be alternatively selected to drive the door-opening push rod 262 to move.

[0109] In the first driving mode, the second servo motor drives the second worm gear to rotate. The rotation of the second worm gear drives the second worm to rotate. The rotation of the second worm drives the coaxial third sprocket to rotate. The rotation of the third sprocket drives the second transmission chain 440 to move and the fourth sprocket to rotate. The movement of the second transmission chain 440 drives the door-opening push rod 262 to extend or retract along the longitudinal direction Y from the main body mounting frame 23.

[0110] The second driving method: manually rotate the door-opening handwheel to drive the fourth worm gear to rotate. The rotation of the fourth worm gear drives the third worm to rotate. The rotation of the third worm drives the coaxial third sprocket to rotate. The rotation of the third sprocket drives the second transmission chain 440 to move and the fourth sprocket to rotate. The movement of the second transmission chain 440 drives the door-opening push rod 262 to extend or retract from the main body mounting bracket 23.

[0111] In a second aspect, the meshing of the second worm gear and the second worm can form a second reduction mechanism. Among them, the third angular velocity and the third torque of the second worm gear are converted into the fourth angular velocity and the fourth torque of the second worm. Among them, the fourth angular velocity is less than the third angular velocity, and the fourth torque is greater than the third torque. In this way, the second rotating shaft 410 can be driven to rotate labor-savingly through the first driving method.

[0112] In a third aspect, the meshing of the third worm gear and the third worm can form a third reduction mechanism. Among them, the fifth angular velocity and the fifth torque of the third worm gear are converted into the sixth angular velocity and the sixth torque of the third worm. Among them, the sixth angular velocity is less than the fifth angular velocity, and the sixth torque is greater than the fifth torque. In this way, the second rotating shaft 410 can be driven to rotate labor-savingly through the second driving method.

The second linear slide rail 264 is slidably matched with the slide rail mounting seat 263 along the longitudinal direction Y. When the door-opening push rod 262 can extend or retract from the main body mounting bracket 23 along the longitudinal direction Y, the second linear slide rail 264 moves relative to the slide rail mounting seat 263 along the longitudinal direction Y.

[0114] In optional example 1, the transverse direction X, the longitudinal direction Y, and the vertical direction Z can be perpendicular to each other in pairs, but it is not limited thereto. In optional example 2, the transverse direction X, the longitudinal direction Y, and the vertical direction Z can also be approximately or substantially perpendicular to each other in pairs.
