Description

Technical Field

[0001] This utility model relates to the field of magnetic field shielding technology, specifically to a connecting device and a sealed chamber. Background Technology

[0002] A sealed compartment is a device that enhances the sealing of a space, typically consisting of a compartment body and a door. However, since the compartment body and door are currently connected by hinges, interference can easily occur at the hinge points when the door is closed, leading to sealing problems. Utility Model Content

[0003] In view of this, the present invention provides a connecting device and a sealed chamber to solve the problem of poor sealing at the connection between the chamber body and the door in existing sealed chambers.

[0004] In a first aspect, this utility model provides a connecting device for connecting the hatch and the body of a sealed chamber, comprising: a connecting rod, one end of which is connected to the body of the chamber via a sliding assembly, and the other end of which is rotatably connected to the hatch via a rotating assembly; the sliding assembly includes a guide rail and a guide slider that slides in cooperation with the guide rail, the guide rail being disposed on one of the connecting rod and the body of the chamber, and the guide slider being disposed on the other of the connecting rod and the body of the chamber.

[0005] Beneficial effects: By sliding one end of the connecting rod to the hull wall and rotating the other end to the hatch, the hatch can be moved away from the hull when opened, increasing its subsequent rotation space and reducing the possibility of interference between the hatch and the hull during rotation. Secondly, when closing the hatch, the tilted hatch is adjusted to be perpendicular to the horizontal plane, and then the connecting rod is used to move the adjusted hatch towards the hatch opening. This allows the hatch to precisely close the hatch opening, improving the fit between the hatch and the hull and ensuring a tight seal.

[0006] In one optional embodiment, the guide slider is disposed on the connecting rod, and the guide rail is adapted to be installed on the side wall of the hull; the length direction of the guide rail and the length direction of the connecting rod are consistent with the hatch direction of the hull.

[0007] Beneficial effects: The cooperation between the guide rail and the guide slider makes the sliding process of the hatch driven by the connecting rod more stable and smooth, reducing the problem of poor sealing at the joint between the hatch and the hull due to uneven sliding, and improving the sealing effect.

[0008] In one alternative embodiment, the sliding assembly further includes a limiting block disposed at one end of the guide rail near the hatch and adapted to abut against the guide slider.

[0009] Beneficial effects: When the hatch is opened to a specific position, the limit block can prevent the guide slider from sliding excessively, avoid the hatch from detaching from the cabin, and ensure the reliability and safety of the hatch opening action.

[0010] In one alternative embodiment, the rotating assembly includes a shaft fixing seat and a damping shaft rotatably connected to the shaft fixing seat, the shaft fixing seat being adapted to be mounted on the side wall of the hatch, and the connecting rod being sleeved on the damping shaft.

[0011] Beneficial effects: The presence of the damping pivot makes the rotation between the connecting rod and the pivot fixed seat controllable. Specifically, on the one hand, operators can flexibly adjust the opening angle of the hatch as needed; on the other hand, during the opening and closing process, the damping pivot acts as a buffer, preventing the hatch from colliding or shaking due to rapid rotation, reducing the risk of hatch damage and extending its service life. Furthermore, since the hatch can be suspended under the damping pivot, it also prevents the hatch from accidentally falling during the opening process.

[0012] In one optional embodiment, the damping shaft is provided with a shaft stop rod rotatably connected to the damping shaft; the shaft fixing seat is also provided with a torsion spring and a push rod located below the shaft stop rod; in the open state, the push rod, under the action of the torsion spring, pushes one end of the shaft stop rod away from the damping shaft to abut against the limiting block.

[0013] Beneficial effects: During the door opening process, the pivot stop rod can rotate upwards under the action of the push rod and the torsion spring until the end of the pivot stop rod away from the damping pivot abuts against the limit block. This, through the cooperation of the pivot stop rod and the limit block, limits the opening angle of the hatch and prevents the hatch from accidentally falling during opening. Furthermore, since the torsion spring is mounted on the hatch via the pivot fixing seat, it undergoes elastic deformation during hatch rotation. When the pivot stop rod abuts against the limit block, the resulting elastic force is greater than the weight of the push rod and the pivot stop rod. Therefore, the push rod locks the position of the pivot stop rod, preventing it from disengaging from the limit block, thus allowing the limit block to continuously restrict the hatch from rotating away from the hull.

[0014] In one optional embodiment, the rotating shaft stop rod has a first protrusion on the side facing the rotating shaft fixing seat, and the rotating shaft fixing seat has a second protrusion on the side facing the rotating shaft stop rod. In the closed state, the second protrusion pushes the end of the rotating shaft stop rod away from the damping rotating shaft and separates it from the limiting block through the first protrusion.

[0015] Beneficial Effects: When the hatch is open, the pivot stop rod remains in contact with the limiting block under the elastic force generated by the torsion spring. At this time, if the hatch is to be closed, the pivot stop rod will prevent the hatch from moving towards the hatch body via the connecting rod, thus preventing the hatch from sealing the hatch body. Based on the above reasons, this embodiment provides a first protrusion on the side of the pivot stop rod facing the pivot fixing seat, and a second protrusion on the side of the pivot fixing seat facing the pivot stop rod. This allows the pivot stop rod to disengage from the limiting block during hatch closing, ensuring the hatch returns to its preset position within the hatch body and creating a sealed space inside the hatch. Specifically, during hatch closing, a certain external force needs to be applied to the hatch to change it from an inclined state to a state perpendicular to the horizontal plane. Therefore, the second protrusion will rotate towards the first protrusion and contact it under the influence of the hatch. In this way, the pivot stop rod can overcome the resistance of the torsion spring and rotate away from the limiting block until it disengages from the limiting block. In this way, the pivot stop rod will not obstruct the movement of the hatch toward the direction of the cabin.

[0016] In one alternative embodiment, the connecting rods are a pair, and the pair of connecting rods are adapted to be disposed on opposite sides of the hatch and the hull.

[0017] Beneficial effects: This symmetrical arrangement makes the connection between the hatch and the hull more secure, enhancing the stability and balance of the structure and avoiding instability or deformation caused by unilateral force. At the same time, the arrangement of a pair of connecting rods can evenly distribute the forces between the hatch and the hull, improving the overall structural reliability and durability.

[0018] In one alternative embodiment, a pair of the connecting rods are adapted to be fitted around the lower end of the sealed chamber.

[0019] Beneficial effects: This utility model assembles the connecting rod on the periphery of the lower end of the sealed chamber, which can increase the opening angle when the chamber door is opened, expand the operating space for operators, and improve the convenience of picking up and putting down items.

[0020] In one optional embodiment, the connecting rod is L-shaped, wherein the free end of the long side of the connecting rod is adapted to be slidably connected to the cabin body, the free end of the short side of the connecting rod is adapted to be rotatably connected to the cabin door, and the free end of the short plate of the connecting rod is set downward.

[0021] Beneficial effects: This utility model connects the free end of the short side of the connecting rod to the hatch in a rotating manner, which can prevent the connecting rod from interfering with other structures located at the hatch during rotation.

[0022] Secondly, this utility model also provides a sealed chamber, comprising:

[0023] The cabin includes an empty compartment and a hatch connected to the empty compartment;

[0024] hatch, adapted to close and seal the hatch opening;

[0025] In the aforementioned connecting device, one end of the connecting rod is slidably connected to the cabin body via a sliding assembly, and the other end is rotatably connected to the cabin door via a rotating assembly.

[0026] Beneficial effects: The sealed chamber of this utility model connects the door and the chamber body by using the above-mentioned connecting device, which not only improves the convenience and smoothness of opening and closing the door, but also ensures the sealing of the sealed chamber when the door is closed.

Detailed Implementation

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0034] To address the problem of poor sealing at the connection between the cabin body and the door in existing sealed cabins, this utility model provides a connection device and a sealed cabin.

[0035] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.

[0036] According to embodiments of the present invention, such as Figure 1 and Figure 2 As shown, a connecting device is provided for connecting the hatch 8 and the cabin body 7 of a sealed chamber, including: a connecting rod 1, one end of which is connected to the cabin body 7 via a sliding assembly 2, and the other end of which is rotatably connected to the hatch 8 via a rotating assembly 3; the sliding assembly 2 includes a guide rail 201 and a guide slider 202 that slides with the guide rail 201, the guide rail 201 being disposed on one of the connecting rod 1 and the cabin body 7, and the guide slider 202 being disposed on the other of the connecting rod 1 and the cabin body 7.

[0037] In this embodiment, one end of the connecting rod 1 is slidably connected to the cabin 7, and the other end of the connecting rod 1 is rotatably connected to the hatch 8. This allows the hatch 8 to move away from the cabin 7 when it is opened, increasing the subsequent rotation space of the hatch 8 and reducing the possibility of interference between the hatch 8 and the cabin 7 during rotation. Secondly, when closing the hatch 8, the tilted hatch 8 is adjusted to be perpendicular to the horizontal plane. Then, the adjusted hatch 8 is moved towards the hatch opening using the connecting rod 1. This allows the hatch 8 to accurately cover the hatch opening, improving the fit between the hatch 8 and the cabin 7 and ensuring the sealing effect of the hatch 8 on the cabin 7.

[0038] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the guide slider 202 is mounted on the connecting rod 1, and the guide rail 201 is adapted to be installed on the side wall of the hull 7; the length direction of the guide rail 201 and the length direction of the connecting rod 1 are consistent with the hatch direction of the hull 7. Through the cooperation of the guide rail 201 and the guide slider 202, the sliding process of the connecting rod 1 driving the hatch 8 is made more stable and smooth, reducing the problem of poor sealing at the joint between the hatch 8 and the hull 7 due to uneven sliding, and improving the sealing effect.

[0039] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the sliding assembly 2 also includes a limiting block 203, which is disposed at one end of the guide rail 201 near the hatch 8 and is adapted to abut against the guide slider 202. When the hatch 8 is opened to a specific position, the limiting block 203 can prevent the guide slider 202 from sliding excessively, avoid the hatch 8 from disengaging from the cabin 7, and ensure the reliability and safety of the hatch 8 opening action.

[0040] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the rotating assembly 3 includes a rotating shaft fixing seat 301 and a damping rotating shaft 302 rotatably connected to the rotating shaft fixing seat 301. The rotating shaft fixing seat 301 is adapted to be mounted on the side wall of the hatch 8, and the connecting rod 1 is sleeved on the damping rotating shaft 302. The presence of the damping rotating shaft 302 makes the rotation between the connecting rod 1 and the rotating shaft fixing seat 301 controllable. Specifically, on the one hand, the operator can flexibly adjust the opening angle of the hatch 8 as needed; on the other hand, during the opening and closing process, the damping rotating shaft 302 can play a buffering role, preventing the hatch 8 from colliding or shaking due to rapid rotation, reducing the risk of damage to the hatch 8, and extending its service life. In addition, since the hatch 8 can be suspended under the damping rotating shaft 302, it can also prevent the hatch 8 from accidentally falling during the opening process.

[0041] According to one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, the damping shaft 302 is equipped with a shaft stop rod 4 rotatably connected to the damping shaft 302; the shaft fixing seat 301 is also equipped with a torsion spring 5 and a push rod 6 located below the shaft stop rod 4; in the open state, the push rod 6, under the action of the torsion spring 5, pushes the end of the shaft stop rod 4 away from the damping shaft 302 to abut against the limiting block 203. During the opening process, the shaft stop rod 4 can rotate upward under the action of the push rod 6 and the torsion spring 5 until the end of the shaft stop rod 4 away from the damping shaft 302 abuts against the limiting block 203. In this way, the opening angle of the hatch 8 can be limited by the cooperation of the shaft stop rod 4 and the limiting block 203, and the hatch 8 can also be prevented from accidentally falling during the opening process. Furthermore, since the torsion spring 5 is mounted on the hatch 8 via the pivot fixing seat 301, the torsion spring 5 will undergo elastic deformation during the rotation of the hatch 8. When the pivot stop rod 4 abuts against the limit block 203, the elastic force generated by it will be greater than the weight of the push rod 6 and the pivot stop rod 4. Therefore, the push rod 6 will lock the position of the pivot stop rod 4 to prevent it from disengaging from the limit block 203, thereby enabling the limit block 203 to continuously restrict the hatch 8 from rotating in a direction away from the cabin 7.

[0042] According to one embodiment of the present invention, such as Figure 2 As shown, the rotating shaft stop rod 4 has a first protrusion 401 on the side facing the rotating shaft fixing seat 301, and the rotating shaft fixing seat 301 has a second protrusion 3011 on the side facing the rotating shaft stop rod 4. In the closed state, the second protrusion 3011 pushes the end of the rotating shaft stop rod 4 away from the damping rotating shaft 302 and separates it from the limiting block 203 through the first protrusion 401. When the hatch 8 is in the open state, the rotating shaft stop rod 4 will remain in contact with the limiting block 203 under the elastic force generated by the torsion spring 5. At this time, if you want to close the hatch 8, the rotating shaft stop rod 4 will prevent the hatch 8 from moving towards the location of the cabin 7 through the connecting rod 1, thus causing the hatch 8 to fail to seal the cabin 7. For the reasons mentioned above, this embodiment provides a first protrusion 401 on the side of the pivot stop rod 4 facing the pivot fixing seat 301, and a second protrusion 3011 on the side of the pivot fixing seat 301 facing the pivot stop rod 4. This allows the pivot stop rod 4 to disengage from the limiting block 203 during the closing of the hatch 8, ensuring that the hatch 8 can return to the preset position of the cabin 7 and forming a sealed space inside the cabin 7. Specifically, during the closing of the hatch 8, since a certain external force needs to be applied to the hatch 8 to change it from an inclined state to a state perpendicular to the horizontal plane, the second protrusion 3011 will rotate in the direction of the first protrusion 401 under the action of the hatch 8 and come into contact with the first protrusion 401. In this way, the pivot stop rod 4 can overcome the resistance of the torsion spring 5 and rotate in a direction away from the limiting block 203 until it disengages from the limiting block 203. In this way, the pivot stop rod 4 will not obstruct the movement of the hatch 8 in the direction of the cabin 7.

[0043] Conversely, it can be deduced that during the opening of hatch 8, the first protrusion 401 and the second protrusion 3011 will rotate along with hatch 8. When the end of the pivot stop rod 4 away from the damping pivot 302 abuts against the limit block 203, the first protrusion 401 will stop rotating, while the second protrusion 3011 will continue to rotate with hatch 8 until hatch 8 stops at the designated position. It should be noted that during the initial process of opening hatch 8, before the end of the pivot stop rod 4 away from the damping pivot 302 abuts against the limit block 203, the first protrusion 401 and the second protrusion 3011 are always in abutting state.

[0044] According to one embodiment of this utility model, the connecting rods 1 are in pairs, and the pair of connecting rods 1 are suitable for being arranged on opposite sides of the hatch 8 and the cabin 7. This symmetrical arrangement can make the connection between the hatch 8 and the cabin 7 more stable, enhance the stability and balance of the structure, and avoid instability or deformation caused by unilateral force. At the same time, the arrangement of the pair of connecting rods 1 can evenly distribute the force between the hatch 8 and the cabin 7, improving the reliability and durability of the overall structure.

[0045] According to one embodiment of the present invention, such as Figure 3 As shown, a pair of connecting rods 1 are adapted to be mounted on the periphery of the lower end of the sealed chamber. In this embodiment, mounting the connecting rods 1 on the periphery of the lower end of the sealed chamber can increase the opening angle of the door 8 when it is opened, expand the operating space for the operator, and improve the convenience of picking up and putting down items.

[0046] According to one embodiment of this utility model, the connecting rod 1 is L-shaped, wherein the free end of the long side of the connecting rod 1 is adapted to be slidably connected to the cabin 7, and the free end of the short side of the connecting rod 1 is adapted to be rotatably connected to the hatch 8, and the free end of the short side of the connecting rod 1 is set downward. This embodiment rotatably connects the free end of the short side of the connecting rod 1 to the hatch 8, which can prevent the connecting rod 1 from interfering with other structures located at the hatch 8 during rotation. It should be noted that both the free end of the long side and the free end of the short side of the connecting rod 1 are the ends furthest from the connection point between them.

[0047] Secondly, such as Figure 3 As shown, this utility model also provides a sealed chamber, including: a chamber body 7, a door 8, and the aforementioned connecting device.

[0048] Specifically, the cabin 7 is provided with an empty cabin and a hatch connected to the empty cabin; the hatch 8 is adapted to close and seal the hatch; one end of the connecting rod 1 in the above-mentioned connecting device is slidably connected to the cabin 7 through the sliding assembly 2, and the other end is rotatably connected to the hatch 8 through the rotating assembly 3.

[0049] In this embodiment, the sealed compartment connects the door 8 and the compartment body 7 using the aforementioned connecting device. This not only improves the convenience and smoothness of opening and closing the door but also ensures the sealing performance of the compartment when the door is closed. Furthermore, the sealed compartment of this embodiment also possesses other advantages of the aforementioned connecting device, which will not be elaborated upon here.

[0050] It should be noted that the sealed chamber in this embodiment includes, but is not limited to, a magnetically shielded chamber.

[0051] According to one embodiment of this utility model, one of the chamber 7 and the hatch 8 facing each other is provided with a snap-fit ​​member 701, and the other is provided with a snap-fit ​​fitting member 801 that snaps into the snap-fit ​​member 701. The snap-fit ​​member 701 or the snap-fit ​​fitting member 801 is located on the outer wall of the chamber 7. In the closed state, the snap-fit ​​member 701 and the snap-fit ​​fitting member 801 are engaged. In the closed state, the snap-fit ​​member 701 and the snap-fit ​​fitting member 801 are engaged, which on the one hand enhances the stability of the connection between the chamber 7 and the hatch 8, prevents the hatch 8 from accidentally loosening or opening during use, and ensures the safety and reliability of the sealed chamber. On the other hand, it allows the hatch 8 to fit more snugly against the chamber 7 in the closed state, thereby reducing the gap between the two and reducing the possibility of external substances such as moisture entering the sealed chamber.

[0052] Understandably, to ensure the fit between the hatch 8 and the cabin 7 when closed, multiple snap-fit ​​pieces 701 or snap-fit ​​mating pieces 801 can be provided on the outer side wall of the cabin 7. For example, the top of the cabin 7 is provided with two snap-fit ​​pieces 701 spaced apart, and the hatch 8 is provided with two snap-fit ​​mating pieces 801 that cooperate with the snap-fit ​​pieces 701.

[0053] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
