Description

Technical Field

[0001] The invention belongs to the technical field of connectors, and particularly relates to a marine sealed electrical connector with a self-tightening structure. Background Art

[0002] In the ship field, marine sealed electrical connectors are key components to ensure the normal operation of various electrical systems. With the continuous development of ship technology, the performance requirements for electrical connectors are becoming increasingly stringent.

[0003] When a ship is sailing, the environment it is in is extremely harsh. On the one hand, the continuous impact of waves causes the hull to vibrate and shake strongly, which poses a huge challenge to the connection stability of the electrical connector. Traditional electrical connectors often have difficulty maintaining a firm connection between the plug and the socket in such a complex dynamic environment, and are prone to loosening or even falling off, thus triggering electrical failures and seriously affecting the normal navigation and safety of the ship. On the other hand, ships operate on water for a long time, and the surrounding environment humidity is always at a high level. It is common to be frequently impacted by waves and splashed by sea water. In addition, during the operation of the ship, electrical equipment will inevitably fail and need to be repaired urgently. During the repair process, if the electrical connector is inconvenient to disassemble, it will greatly delay the repair time and affect the operation efficiency of the ship. For this reason, our potato chip processing device and its production method solve the above problems. Utility Model Content

[0004] The purpose of the invention is to provide a marine sealed electrical connector with a self-tightening structure for the above-mentioned existing technical problems, achieving the effects of convenience in device installation, protection during use, and rapidity in staff maintenance.

[0005] In view of this, the invention provides a marine sealed electrical connector with a self-tightening structure, including a connector housing. A main wire is arranged at the left end of the connector housing. A plurality of symmetrically arranged outer grooves are formed on the surface of the main wire. A secondary wire is arranged on the right side of the connector housing. A plurality of symmetrically arranged inner grooves are formed on the inner wall of the secondary wire. An annular groove is formed on the inner wall of the connector housing. A plurality of placement grooves communicating with the right end of the connector housing are formed at the left end of the connector housing. A sliding groove is formed on the inner wall of each of the plurality of placement grooves, and the plurality of sliding grooves are uniformly communicated with the surface of the connector housing. A plurality of symmetrically arranged T-shaped support columns are fixedly connected to the left end of the connector housing. A self-locking mechanism is arranged inside the connector housing. A sealing mechanism is arranged in the annular groove. A quick-release mechanism is arranged in the sliding groove.

[0006] In this technical solution, by arranging the outer grooves and the inner grooves, the outer grooves, the inner grooves and the self-locking mechanism can be conveniently connected to each other during use, improving the installation speed of the connector.

[0007] In the above technical solution, further, the self-locking mechanism includes a first spring, the first spring is fixedly connected to the left end of the connector housing, the other end of the first spring is fixedly connected to an annular pressing piece, the left end of the annular pressing piece is fixedly connected to a plurality of symmetrically arranged racks, the inner wall of the connector housing is provided with a plurality of symmetrically arranged gear grooves, the plurality of gear grooves communicate with the annular groove, the inner wall of the connector housing is provided with a plurality of symmetrically arranged limiting grooves, the plurality of limiting grooves communicate with the gear grooves and the annular groove respectively, a small gear is rotatably connected to the inner wall of the plurality of gear grooves, a hollow square block is slidably connected to the inner wall of the plurality of limiting grooves, a limiting post is arranged on the upper surface of the plurality of hollow square blocks, the lower end of the limiting post penetrates through the upper surface of the hollow square block and extends to the inside, a second spring is arranged in the plurality of hollow square blocks, a clamping block is fixedly connected to the inner end of the plurality of limiting posts, a plurality of symmetrically arranged L-shaped clamping grooves are formed in the right end of the annular pressing piece, a third spring is fixedly connected to the inner wall of the plurality of L-shaped clamping grooves, the upper end of the third spring is fixedly connected to an L-shaped support rod, and a plurality of symmetrically arranged fourth springs are fixedly connected to the inner walls of the plurality of placing grooves.

[0008] In this technical solution, by providing an annular pressing piece, a continuous pre-tightening force to the right can be provided during use. This pre-tightening force helps the annular pressing piece to closely fit on the internal structure of the connector, ensuring that the subsequent locking mechanism can work effectively.

[0009] In the above technical solution, further, the sealing mechanism includes a plurality of connecting columns, the right ends of the plurality of connecting columns are respectively fixedly connected to the left ends of the plurality of racks, the left ends of the plurality of connecting columns are fixedly connected to the same annular support piece, the right end of the annular support piece is fixedly connected to a plurality of symmetrically arranged first piston rods, a plurality of first air pressure cavities communicating with the annular groove are formed in the connector housing, the plurality of first piston rods are matched with the first air pressure cavities, a first annular air pressure groove is formed in the inner wall of the connector housing, the first annular air pressure groove communicates with the plurality of first air pressure cavities, a first annular rubber film is fixedly connected to the inner wall of the first annular air pressure groove, a hollow cylinder is fixedly connected to the right end of the connector housing, a plurality of symmetrically arranged second air pressure cavities are formed in the right end of the hollow cylinder, a second annular air pressure groove is formed in the inner wall of the hollow cylinder, the second annular air pressure groove communicates with the plurality of second air pressure cavities, a second annular rubber film is fixedly connected to the inner wall of the second annular air pressure groove, a second piston rod is slidably connected to the inner wall of the plurality of second air pressure cavities, the right end of the second piston rod is fixedly connected to the same annular blocking piece, and a fifth spring is fixedly connected to the right end of the hollow cylinder.

[0010] In this technical solution, the connecting column serves as an intermediate connecting piece, transmitting the movement of the rack to the annular support piece, enabling the linear movement of the rack to be converted into corresponding actions of the annular support piece, thereby driving the subsequent components related to sealing to work.

[0011] In the above technical solution, further, the quick-release mechanism includes a plurality of storage grooves, which are opened on the surface of the connector housing. The inner walls of the plurality of storage grooves are rotatably connected with spur gears, and the inner walls of the storage grooves are rotatably connected with spur gears. The spur gears are meshed with the spur gears. The inner walls of the storage grooves are slidably connected with slide bars, and the side walls of the spur gears are meshed with the slide bars. A rotating ring is sleeved on the surface of the connector housing, and a plurality of tooth grooves are opened on the inner wall of the rotating ring, and the plurality of tooth grooves are meshed with the spur gears.

[0012] In this technical solution, the storage grooves provide a dedicated accommodation space for parts such as spur gears, spur gears, and slide bars. In the complex environment of a ship, these internal parts can be protected from external collisions, seawater erosion, and interference from foreign objects such as dust, ensuring the normal operation of the parts.

[0013] In the above technical solution, further, the pinion gear is meshed with the left side wall of the hollow square block. The inner wall of the hollow square block is fixedly connected to the upper end of the second spring, and the lower end of the second spring is fixedly connected to the upper surface of the block. The second spring is sleeved on the surface of the limiting post.

[0014] In this technical solution, the upper end of the second spring is fixed to the inner wall of the hollow square block, enabling the hollow square block to transmit elastic force through the second spring during movement. When the hollow square block is subjected to external pressure or tension, the spring can play a buffering and shock-absorbing role, reducing the impact force on the mechanism and protecting other components from damage.

[0015] In the above technical solution, further, the first annular film and the second annular film are both made of silicone rubber material, and threaded strips are fixedly connected to the inner walls of the first annular film and the second annular film.

[0016] In this technical solution, silicone rubber itself has extremely low water absorption and can effectively prevent water penetration. When the first annular film and the second annular film are made of silicone rubber material, they can form a reliable waterproof barrier between the connector housing and the internal structure, preventing seawater.

[0017] In the above technical solution, further, the first spring, the second spring, the third spring, the fourth spring, and the fifth spring are all made of rare earth metal material.

[0018] In this technical solution, the spring made of rare earth metal alloy has high strength and can withstand greater loads.

[0019] In the above technical solution, further, the sizes of the plurality of outer grooves and the clamping blocks are the same, the sizes of the plurality of inner grooves and the right ends of the L-shaped support rods are the same, the right end of the L-shaped support rod passes through the placement groove and extends to the right end of the connector housing, the upper end of the fourth spring abuts against the bottom surface of the L-shaped support rod, and the shape of the right end of the L-shaped support rod is triangular.

[0020] In this technical solution, the same sizes of the outer grooves and the clamping blocks can ensure precise fit when the clamping blocks are inserted into the outer grooves. This tight fit method can effectively prevent the clamping blocks from shaking or displacing under complex working conditions such as ship vibration and swaying.

[0021] The beneficial effects of the present invention are:

[0022] 1. For the marine sealed electrical connector with a self-tightening structure, during the ship's navigation, it will continuously be impacted by sea waves, generating continuous vibration and swaying. The self-locking mechanism of the marine electrical connector can ensure a firm connection between the plug and the socket in this complex dynamic environment. Then, the connector of the self-locking mechanism is easy to operate and quickly lock during assembly, saving operation time.

[0023] 2. For the marine sealed electrical connector with a self-tightening structure, during the long-term navigation of the ship on water, the surrounding environment has high humidity and is often impacted by sea waves and splashed by sea water. The sealing mechanism can effectively prevent sea water, rain water, and humid air from entering the interior of the electrical connector. Then, the salt mist in the marine environment has strong corrosiveness. The sealing mechanism of the electrical connector can form a relatively enclosed space to prevent the salt mist from contacting the internal metal contacts and electronic components. This is crucial for protecting the electrical performance and mechanical performance of the electrical connector, can extend its service life, and reduce failures and maintenance costs caused by corrosion.

[0024] 3. For the marine sealed electrical connector with a self-tightening structure, during the operation of the ship, when an electrical device fails and needs emergency repair, the quick-release mechanism can enable maintenance personnel to quickly separate the electrical connector, so as to quickly locate and replace the faulty components. The marine electrical equipment needs to be regularly maintained and inspected. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] Embodiment 1:

[0044] Please refer to Figure 1 - Figure 11 As shown, this embodiment provides a marine sealed electrical connector with a self-tightening structure, including a connector housing 1. A main wire 2 is arranged at the left end of the connector housing 1. A plurality of symmetrically arranged outer grooves 3 are formed on the surface of the main wire 2. A secondary wire 4 is arranged on the right side of the connector housing 1. A plurality of symmetrically arranged inner grooves 5 are formed on the inner wall of the secondary wire 4. An annular groove 6 is formed on the inner wall of the connector housing 1. A plurality of placement grooves 7 communicating with the right end of the connector housing 1 are formed at the left end of the connector housing 1. A sliding groove 8 is formed on the inner wall of each of the plurality of placement grooves 7. The plurality of sliding grooves 8 are uniformly communicated with the surface of the connector housing 1. A plurality of symmetrically arranged T-shaped support columns 9 are fixedly connected to the left end of the connector housing 1. A self-locking mechanism is arranged inside the connector housing 1. A sealing mechanism is arranged in the annular groove 6. A quick-release mechanism is arranged in the sliding groove 8.

[0045] Among them, the T-shaped support columns 9 can provide additional support for the connection between the electrical connector and external equipment. After the electrical connector is connected to the plug, the T-shaped support columns 9 can be combined with the housing or bracket and other structures of the external equipment to share a part of the tensile force, pressure or torque generated by the connection. In the environment of ship vibration and sway, this support function can reduce the force at the interface of the electrical connector and improve the stability and reliability of the connection.

[0046] As can be seen from this embodiment, the self-locking mechanism ensures that the plug and the socket can be tightly and firmly connected in the complex vibration and rocking environment of the ship. The sealing mechanism prevents external harmful substances such as seawater, salt spray, and dust from entering the inside of the connector, avoiding electrical failures caused by these factors. The quick-release mechanism can quickly and safely separate the connection when needed, facilitating maintenance and replacement. The three work together to enhance the overall reliability of the electrical connector from multiple aspects such as connection stability, protection, and maintainability, ensuring the stable operation of the ship's electrical system.

[0047] Embodiment 2:

[0048] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The self-locking mechanism includes a first spring 10, which is fixedly connected to the left end of the connector housing 1. The other end of the first spring 10 is fixedly connected with an annular pressing piece 11. The left end of the annular pressing piece 11 is fixedly connected with a plurality of symmetrically arranged racks 12. A plurality of symmetrically arranged gear grooves 13 are opened on the inner wall of the connector housing 1. The plurality of gear grooves 13 communicate with the annular groove 6. A plurality of symmetrically arranged limiting grooves 14 are opened on the inner wall of the connector housing 1. The plurality of limiting grooves 14 communicate with the gear grooves 13 and the annular groove 6 respectively. A small gear 15 is rotatably connected to the inner wall of the plurality of gear grooves 13. A hollow square block 16 is slidably connected to the inner wall of the plurality of limiting grooves 14. A limiting column 17 is arranged on the upper surface of the plurality of hollow square blocks 16. The lower end of the limiting column 17 penetrates through the upper surface of the hollow square block 16 and extends to the inside. A second spring 18 is arranged inside the plurality of hollow square blocks 16. A clamping block 19 is fixedly connected to the inner end of each of the plurality of limiting columns 17. A plurality of symmetrically arranged L-shaped clamping grooves 20 are opened on the right end of the annular pressing piece 11. A third spring 21 is fixedly connected to the inner wall of the plurality of L-shaped clamping grooves 20. The upper end of the third spring 21 is fixedly connected with an L-shaped support rod 22. A plurality of symmetrically arranged fourth springs 23 are fixedly connected to the inner wall of the plurality of placement grooves 7.

[0049] Among them, the shape and size design of the rack can ensure its meshing accuracy with the small gear, making the motion transmission accurate and error-free. This is crucial for ensuring the reliability of the entire self-locking mechanism and can precisely control the positions of components such as the limiting column and the clamping block, thereby achieving stable locking.

[0050] As can be seen from this embodiment, when the plug is inserted into the connector housing 1, the plug will push the annular pressing piece 11 to move rightward. Then, the annular pressing piece 11 compresses the first spring 10 and drives the rack 12 to move rightward. After that, the rightward movement of the rack 12 drives the meshing pinion 15 to rotate. The rotation of the pinion 15 drives the meshing hollow square block 16 to slide downward in the limiting groove 14. When the hollow square block 16 moves downward, the second spring 18 is compressed, and at the same time, the limiting post 17 and the clamping block 19 are driven to move downward. When the plug is completely inserted in place, under the elastic force of the second spring 18, the clamping block 19 is clamped into the outer groove 3 to achieve preliminary locking. When the annular pressing piece 11 moves rightward, it drives the L-shaped support rod 22 to move rightward. After that, when the auxiliary wire 4 is inserted and touches the right end of the L-shaped support rod 22, the auxiliary wire 4 will press the plurality of L-shaped support rods 22 downward, and then the right end of the L-shaped support rod 22 is clamped into the inner groove 5 to achieve final locking.

[0051] Embodiment 3:

[0052] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The sealing mechanism includes a plurality of connecting columns 24. The right ends of the plurality of connecting columns 24 are respectively fixedly connected to the left ends of the plurality of racks 12. The left ends of the plurality of connecting columns 24 are fixedly connected to the same annular support piece 25. The right end of the annular support piece 25 is fixedly connected to a plurality of symmetrically arranged first piston rods 26. A plurality of first air pressure cavities 27 communicating with the annular groove 6 are formed in the connector housing 1. The plurality of first piston rods 26 are matched with the first air pressure cavities 27. The inner wall of the connector housing 1 is provided with a first annular air pressure groove 28. The first annular air pressure groove 28 communicates with the plurality of first air pressure cavities 27. The inner wall of the first annular air pressure groove 28 is fixedly connected to a first annular film 29. The right end of the connector housing 1 is fixedly connected to a hollow cylinder 30. The right end of the hollow cylinder 30 is provided with a plurality of symmetrically arranged second air pressure cavities 31. The inner wall of the hollow cylinder 30 is provided with a second annular air pressure groove 32. The second annular air pressure groove 32 communicates with the plurality of second air pressure cavities 31. The inner wall of the second annular air pressure groove 32 is fixedly connected to a second annular film 33. A second piston rod 34 is slidably connected to the inner walls of the plurality of second air pressure cavities 31. The right end of the second piston rod 34 is fixedly connected to the same annular blocking piece 35. The right end of the hollow cylinder 30 is fixedly connected to a fifth spring 36.

[0053] Among them, the annular support piece can centrally bear the force from the connecting columns and reasonably distribute it to each first piston rod. At the same time, it also provides stable support and positioning for the first piston rod, ensuring that the first piston rod always maintains the correct direction and position during the movement process.

[0054] As can be seen from this embodiment, the movement of the rack 12 will drive the connecting column 24 fixedly connected thereto to move synchronously. Since the left ends of the plurality of connecting columns 24 are fixedly connected to the annular support sheet 25 together, the annular support sheet 25 will also move with the connecting column 24. When the annular support sheet 25 moves to the right, a plurality of first piston rods 26 fixed to its right end will correspondingly slide in the first air pressure cavity 27 in the connector housing 1. As the first piston rod 26 acts in the first air pressure cavity 27, the gas pressure in the first air pressure cavity 27 will change. And since the first annular air pressure groove 28 is connected to the plurality of first air pressure cavities 27, the gas pressure will be transmitted and balanced in this connected space, so that the first annular film 29 in the first annular air pressure groove 28 is affected by the gas pressure, and thus closely adheres to the surface of the plug, playing a preliminary sealing role to prevent liquid from infiltrating from this area. At the same time, the hollow cylinder 30 fixedly connected to the right end of the connector housing 1 also participates in the sealing process. When the right plug is inserted, the plug will squeeze the annular baffle 35 to move leftward. While moving, the fifth spring 36 is squeezed and tightened. At this time, the second piston rod 34 will also be squeezed at the same time. When being squeezed, the second piston rod 34 pushes the air in the second air pressure cavity 31 to generate pressure. After that, the second annular film 33 is affected by the gas pressure, and thus closely adheres to the surface of the plug to complete the final sealing, preventing the intrusion of external substances and the leakage of internal substances, and ensuring the normal operation of the device and the stability of the internal environment.

[0055] Embodiment 4:

[0056] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The quick-release mechanism includes a plurality of storage grooves 37. The storage grooves 37 are opened on the surface of the connector housing 1. The inner walls of the plurality of storage grooves 37 are rotatably connected with spur gears 38. The inner walls of the storage grooves 37 are rotatably connected with positive gears 39. The positive gears 39 are meshed and connected with the spur gears 38. The inner walls of the storage grooves 37 are slidably connected with slide bars 40. The positive gears 39 are meshed with the side walls of the slide bars 40. A rotating ring 41 is sleeved on the surface of the connector housing 1. A plurality of tooth grooves 42 are opened on the inner wall of the rotating ring 41. The plurality of tooth grooves 42 are meshed and connected with the spur gears 38.

[0057] Among them, the spur gear 38, as a key transmission component in the quick-release mechanism, can convert the rotational movement of the rotating ring 41 into the rotational movement of the positive gear 39. Through meshing with the positive gear, the transmission of force and the change of the movement direction are realized, providing power for the subsequent movement of the slide bar. This transmission method is simple and efficient.

[0058] As can be seen from this embodiment, when a disassembly operation is required, an external force is applied to the swivel ring 41 to make it rotate. During the rotation of the swivel ring 41, the tooth grooves 42 on its inner wall will engage with the spur gears 38 in the storage grooves 37, thereby driving the spur gears 38 to rotate. Since the spur gears 38 are meshed and connected to the spur gears 39, the rotation of the spur gears 38 will be transmitted to the spur gears 39, causing the spur gears 39 to rotate accordingly. When the spur gears 39 rotate, their meshing relationship with the side walls of the slide bars 40 will cause the slide bars 40 to slide on the inner walls of the storage grooves 37. The sliding direction and displacement of the slide bars 40 depend on the rotation direction and angle of the spur gears 39. Through the synchronous movement of multiple slide bars 40, the L-shaped support rods 22 are squeezed downward, and then the L-shaped support rods 22 will disengage from the plugs on the right. At this time, the device on the left will reset to achieve convenient disassembly and installation operations, improving the maintenance and assembly efficiency of the equipment.

[0059] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features: the pinion gear 15 is meshed and connected to the left side wall of the hollow square block 16. The inner wall of the hollow square block 16 is fixedly connected to the upper end of the second spring 18. The lower end of the second spring 18 is fixedly connected to the upper surface of the latch 19. The second spring 18 is sleeved on the surface of the limit post 17.

[0060] Among them, the movement of the hollow square block 16 can directly affect the expansion and contraction state of the second spring, and then transmit the force to other components such as the latch through the second spring.

[0061] As can be seen from this embodiment, when an external force acts on the pinion gear 15 to make it rotate, since the pinion gear 15 is meshed and connected to the left side wall of the hollow square block 16, the rotation of the pinion gear 15 will be converted into the downward movement of the hollow square block 16. When the hollow square block 16 moves downward, it will compress the second spring 18 sleeved on the surface of the limit post 17. At this time, the second spring 18 stores elastic potential energy, and at the same time drives the connected latch 19 to move upward, so that the latch 19 disengages from the engagement or contact state with other components, realizing the unlocking or separation function. When the external force acting on the pinion gear 15 disappears, under the action of the elastic restoring force of the second spring 18, the hollow square block 16 will move upward, driving the latch 19 back to the initial position and reforming the engagement or contact relationship with the corresponding components to complete the locking or connection operation.

[0062] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features: both the first annular film 29 and the second annular film 33 are made of silicone rubber material, and threaded strips are fixedly connected to the inner walls of the first annular film 29 and the second annular film 33.

[0063] Among them, the existence of the threaded strips increases the contact area and friction force between the film and the sealing surface. When the film is pressed tightly against the sealing surface under the action of air pressure, the threaded strips are like small sealing ribs, which can effectively prevent the flow of gas or liquid in the micro-channels between the film and the sealing surface.

[0064] As can be seen from this embodiment, silicone rubber is a highly elastic polymer material. Its molecular chain is composed of alternating silicon atoms and oxygen atoms. This structure makes the molecular chain have good flexibility and elasticity. When subjected to external pressure, the silicone rubber molecular chain can deform, so as to closely fit on the sealing surface. In the sealing mechanism, the first annular film 29 and the second annular film 33 utilize this elastic deformation to fill the micro-gaps between the sealing surfaces. Under the action of air pressure, the film will be extruded towards the sealing surface, and the silicone rubber molecular chain will be like countless small springs, adaptively filling into the gaps to prevent the passage of gas or liquid.

[0065] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features: the first spring 10, the second spring 18, the third spring 21, the fourth spring 23, and the fifth spring 36 are all made of rare earth metal materials.

[0066] Among them, the rare earth metal spring can withstand large elastic deformations without permanent deformation, and is not prone to fatigue damage during repeated stretching and contraction.

[0067] As can be seen from this embodiment, after the first spring 10, the second spring 18, the third spring 21, the fourth spring 23, and the fifth spring 36 are deformed under force, relying on the advantages of rare earth metal materials, such as good temperature stability and dimensional accuracy retention, even under complex environmental conditions, they can still accurately pull the connecting components back to the predetermined position, providing a solid guarantee for the continuous and reliable operation of the device.

[0068] This embodiment provides a marine sealed electrical connector with a self-tightening structure. In addition to including the technical solutions of the above embodiments, it also has the following technical features: the sizes of the multiple outer grooves 3 are the same as those of the clamping blocks 19, the sizes of the multiple inner grooves 5 are the same as the right ends of the L-shaped support rods 22. The right end of the L-shaped support rod 22 passes through the placement groove 7 and extends to the right end of the connector housing 1. The upper end of the fourth spring 23 abuts against the bottom surface of the L-shaped support rod 22, and the shape of the right end of the L-shaped support rod 22 is triangular.

[0069] Among them, when the clamping block 19 is in close fit with the outer groove 3, the stress generated under the action of external force can be better transmitted and dispersed on the contact surface between the two, reducing local stress concentration, thereby improving the stability of the connection.

[0070] As can be seen from this embodiment, the inner groove 5 and the right end of the L-shaped support rod 22 are of the same size, and the right end of the L-shaped support rod 22 passes through the placement groove 7 and extends to the right end of the connector housing 1. This design provides good guidance and limiting effects for the L-shaped support rod 22. During the operation of the device, the L-shaped support rod 22 can move stably along the inner groove 5 without deviation or shaking, ensuring the accuracy and stability of its movement. At the same time, the inner groove 5 limits the movement range of the L-shaped support rod 22, enabling it to move only within the specified path, thereby ensuring the normal operation of the entire device.

[0071] The embodiments of the present application have been described above in conjunction with the accompanying drawings. Without conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above specific embodiments. The above specific embodiments are merely illustrative rather than restrictive. Under the inspiration of the present application, those of ordinary skill in the art can also make many forms without departing from the purpose of the present application and the scope protected by the claims, and all of them belong to the protection scope of the present application.
