Description

Technical Field

[0001] This application relates to the field of carbon fiber enclosures, and more particularly to a carbon fiber enclosure sealing structure. Background Technology

[0002] Carbon fiber enclosures are generally used in special sealing requirements or special environments, so the sealing performance of carbon fiber is required to be high. This requires that the door of the carbon fiber enclosure and the door frame close tightly when the door is closed. Therefore, the fit clearance between the contact surfaces of the door frame and the door is required to be high, and the processing requirements of the contact surfaces of the door frame and the door are also high, resulting in high processing costs for carbon fiber enclosures. Summary of the Invention

[0003] To reduce the processing cost of carbon fiber enclosures, this application provides a carbon fiber enclosure sealing structure.

[0004] This application provides a carbon fiber housing sealing structure using the following technical solution: A carbon fiber box sealing structure is applied to a carbon fiber box. The carbon fiber box includes a door frame and a door panel. A groove with a shape consistent with the cross-sectional shape of the door frame is provided on the door frame. An inflatable sealing ring is provided in the groove. The door frame has a cavity around the groove along its length. Connecting blocks are fixedly connected to the upper and lower surfaces of the sealing ring along its length. The connecting blocks penetrate the side wall of the door frame and are slidably inserted into the cavity. A highly extendable telescopic plate is slidably connected in the cavity. The telescopic plate slides along the depth direction of the door frame. The cavity is also equipped with a control component for controlling the extension and retraction of the telescopic plate. In the initial state, the distance between the surfaces of the two telescopic plates that are close to each other is greater than the distance between the surfaces of the two connecting blocks that are far apart from each other. The cavity is also equipped with a drive assembly for driving the telescopic plate to slide, and the door frame is equipped with a locking assembly for fixing the telescopic plate.

[0005] By adopting the above technical solution, the operator places the inflatable sealing ring into the groove, and the connecting block slides into the cavity. At this time, the distance between the surfaces of the two telescopic plates that are close to each other is greater than the distance between the surfaces of the two connecting blocks that are far apart. Therefore, the operator can continue to push the inflatable sealing ring into the groove. At the same time, the control component works to extend the telescopic plate, and the drive component also drives the telescopic plate to move away from the door panel. When the inflatable sealing ring is in place, the operator uses the locking component to fix the telescopic plate, thereby fixing the connecting block and the inflatable sealing ring. When the door panel is closed, the inflatable sealing ring seals the gap between the door frame and the door panel, making the allowable fit error range of the contact surfaces of the door panel and the door frame wider, reducing the processing requirements of the door frame and the door, thereby reducing the processing cost of the carbon fiber box.

[0006] Optionally, the telescopic plate includes a sleeve plate with grooves, the grooves of the two sleeve plates facing the side close to the inflatable sealing ring, a plurality of connecting springs connected to the bottom wall of the groove of the sleeve plate, and a plug plate slidably inserted into the groove of the sleeve plate, the plug plate being connected to the connecting spring.

[0007] By adopting the above technical solution, the plug plate moves along the sleeve plate, and the connecting spring deforms as the plug plate moves. The plug plate, the connecting spring and the sleeve plate cooperate to allow the overall height of the plug plate and the sleeve plate to be extended and retracted.

[0008] Optionally, a T-shaped slider is fixedly connected to the outer bottom wall of the sleeve plate. A groove adapted to the slider is opened on the cavity wall corresponding to the slider. The length direction of the groove is set along the depth direction of the door frame, and the slider is slidably inserted into the groove.

[0009] By adopting the above technical solution, the slider and the groove cooperate to make the sleeve plate slide with the door frame, thereby enabling the telescopic plate to slide.

[0010] Optionally, the drive assembly includes a rope reel installed in the cavity, a gear fixedly connected to the rope reel, the gear being rotatably installed in the cavity, a pull rope wound on the rope reel, the two ends of the pull rope being fixedly connected to corresponding sliders, and a rack meshing with the gear fixedly connected to the inflatable sealing ring, the rack penetrating the groove wall corresponding to the groove and extending into the cavity; A return spring is connected to the side of the slider closest to the door frame, and the side of the return spring away from the slider is connected and fixed to the cavity wall corresponding to the cavity.

[0011] By adopting the above technical solution, in the initial state, the return spring limits the slider, and the control component limits the telescopic plate, so that the two telescopic plates are located on the side of the door frame closer to the door panel. When the operator inserts the inflatable sealing ring into the groove, the rack is inserted into the cavity, and the rack meshes with the gear ring. As the operator continues to push the inflatable sealing ring into the groove, the inflatable sealing ring drives the rack to move, and the rack drives the gear and the rope winding wheel to rotate. The rotation of the rope winding wheel winds the pull rope around the rope winding wheel, and the pull rope can pull the slider and the corresponding sleeve plate to move. At the same time, the slider compresses the return spring.

[0012] When the operator pulls the inflatable sealing ring out of the groove, the inflatable sealing ring drives the rack to move, the rack drives the gear and the rope winding wheel to rotate, the rope winding wheel rotates to release the pull rope, and at the same time the return spring restores its deformation and pushes the pull rope, the slider and the sleeve to move.

[0013] Optionally, the control component includes a sliding block that is slidably inserted into a slide groove. The sliding block is located on the side of the slider near the outside of the door frame. The pull rope passes through the slider and is fixed to the sliding block. A limiting spring is provided between the slider and the sliding block. The two ends of the connecting spring are fixed to the slider and the sliding block respectively. A hinge rod is hinged on the sliding block. The end of the hinge rod away from the sliding block is hinged to the insertion plate.

[0014] By adopting the above technical solution, when the winding wheel winds and retracts the pull rope, the pull rope drives the sliding block to move, causing the sliding block to move closer to the slider. At the same time, the sliding block drives the corresponding end of the hinge rod to move, and the hinge rod rotates closer to the sleeve plate. Simultaneously, the upper end of the hinge rod pushes the plug plate upward, thereby extending the telescopic plate. When the limit spring is compressed to its limit, as the pull rope continues to pull the sliding block, the sliding block drives the slider to move, and the slider compresses the reset spring.

[0015] When the return spring recovers its deformation and pushes the slider to move to the initial position, the limit spring also recovers its deformation and pushes the sliding block to move to the initial position. The movement of the sliding block causes the hinge rod to rotate and return to its original position. At the same time, the connecting spring recovers its deformation and causes the plug plate to move into the sleeve plate, causing the telescopic plate to shorten. When the return spring, connecting spring and limit spring return to their initial state, the telescopic plate retracts to its initial length.

[0016] Optionally, a plurality of limiting rings for fixing the pull rope are fixedly connected to the cavity wall, and the plurality of limiting rings are distributed along the length direction of the pull rope.

[0017] By adopting the above technical solution, the limiting ring limits the pull rope, reducing the occurrence of the pull rope getting tangled and knotted.

[0018] Optionally, a rigid plate is provided between the inflatable sealing ring and the rack, the rigid plate being fixed to the inflatable sealing ring and the rack being fixed to the rigid plate.

[0019] By adopting the above technical solution, the force on the inflatable sealing ring is more even, reducing the occurrence of damage to the inflatable sealing ring caused by the rack.

[0020] Optionally, the locking assembly includes a screw threaded onto a surface of the door frame located inside the carbon fiber housing, the screw portion being located within the cavity.

[0021] By adopting the above technical solution, when the telescopic plate moves, the upper end face of the screw is lower than the inner bottom wall of the cavity. After the telescopic plate moves into place, the screw is turned so that the screw protrudes from the inner bottom wall of the cavity. The screw can limit the telescopic plate, and the telescopic plate limits the connecting block and the inflatable sealing ring.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By incorporating grooves, inflatable sealing rings, cavities, connecting blocks, telescopic plates, control components, drive components, and locking components, the processing cost of the carbon fiber housing is reduced; 2. The telescopic plate can be driven to move by setting up a rope reel, gears, pull rope, slider, rack and pinion, and return spring; 3. The extension and retraction of the telescopic plate can be controlled by setting sliding blocks, limit springs, and hinge rods. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a carbon fiber housing sealing structure. (Refer to...) Figure 1 and Figure 2 The device is mounted on a carbon fiber housing, which includes a door frame 1 and a door panel 2. A groove 11 is formed on the side wall of the door frame 1 near the door panel 2, and the shape of the groove 11 matches the shape of the longitudinal section of the door panel 2. A cavity 12 is formed around the door frame 1 along the length of the groove 11. A corresponding inflatable sealing ring 3 is provided in the groove 11, and a rigid plate 4 is fixedly connected to the side of the inflatable sealing ring 3 closest to the inside of the door frame 1. The rigid plate 4 is inserted into the groove 11.

[0030] Reference Figure 2 and Figure 3A connecting block 31 is vertically fixed to the middle of the upper and lower surfaces of the inflatable sealing ring 3 along its length. A mating block is fixedly connected to the connecting block 31, and the cross-sectional area of ​​the mating block is larger than that of the connecting block 31. A strip hole 13 adapted to the connecting block 31 is opened on the two opposite long side groove walls of the groove 11. The strip hole 13 communicates with the cavity 12, and the length of the strip hole 13 is set along the depth direction of the door frame 1.

[0031] A telescopic plate 5 is slidably connected to both the upper and lower walls of the cavity 12. The telescopic plate 5 is set along the length of the door panel 2 and is telescopic in the height direction. The telescopic plate 5 includes a sleeve plate 51 with a groove. Multiple connecting springs 52 are fixedly connected to the bottom wall of the groove of the sleeve plate 51. The multiple connecting springs 52 are distributed along the length of the sleeve plate 51. A plug plate 53 is slidably inserted into the groove of the sleeve plate 51, and the connecting springs 52 are fixedly connected to the plug plate 53.

[0032] T-shaped sliders 511 are fixedly connected to the outer bottom walls of both sleeve plates 51. Slide grooves 14 adapted to the sliders 511 are opened on the upper and lower cavity walls of the cavity 12. The length direction of the slide grooves 14 is set along the depth direction of the door frame 1. Each slider 511 is slidably inserted into the corresponding slide groove 14. The sliders 511 and slide grooves 14 cooperate to make the telescopic plate 5 slide and cooperate with the cavity 12. The connecting spring 52 limits the insertion plate 53 so that the gap between the surfaces of the two insertion plates 53 that are close to each other is d1, and the distance between the surfaces of the two mating blocks that are far from each other is less than d1.

[0033] The cavity 12 is provided with a drive assembly 6 that drives the telescopic plate 5 to slide along the depth direction of the door frame 1. The drive assembly 6 includes a rack 61 that is vertically fixedly connected to the side wall of the rigid plate 4 away from the inflatable sealing ring 3. The length direction of the rack 61 is set along the depth direction of the door frame 1. The groove wall of the groove 11 is provided with a hole for the rack 61 to be inserted into the cavity 12. A support rod is vertically fixedly connected to the cavity wall of the cavity 12 near the inside of the door frame 1. The end of the support rod is rotatably connected to a gear 63 that meshes with the rack 61.

[0034] A rope reel coaxial with the gear 63 is fixedly connected to one end face of the gear 63. A pull rope 65 is wound on the rope reel. One end of the pull rope 65 passes through one slider 511, and the other end passes through another slider 511. A return spring 66 is fixedly connected to the side of the slider 511 closest to the inside of the door frame 1. The return spring 66 is located in the slide groove 14. The end of the return spring 66 away from the slider 511 is fixed to the groove wall of the corresponding end of the slide groove 14. The return spring 66 limits the slider 511 and the telescopic plate 5, so that the telescopic plate 5 is located on the side of the cavity 12 closest to the door panel 2. Multiple limiting rings are fixedly connected to the cavity wall of the cavity 12. The multiple limiting rings are arranged along the length direction of the pull rope 65. The pull rope 65 passes through the limiting rings, and the limiting rings guide the pull rope 65.

[0035] The cavity 12 is also equipped with a control component 7 for driving the telescopic plate 5 to extend and retract. The control component 7 includes a hinge rod 71 hinged to the side wall of the plug plate 53 near the door panel 2. The sleeve plate 51 is provided with a connecting groove 512 for the hinge rod 71 to pass through. The length direction of the connecting groove 512 is set along the height direction of the door frame 1. A sliding block 72 is hinged to the end of the hinge rod 71 away from the plug plate 53. The sliding block 72 is slidably inserted into the corresponding sliding groove 14, and the sliding block 72 is located on the side of the slider 511 near the door panel 2. Both ends of the pull rope 65 are fixed to the corresponding sliding block 72.

[0036] A limiting spring 73 is provided between the sliding block 72 and the slider 511. The two ends of the limiting spring 73 are fixed to the sliding block 72 and the slider 511 respectively. The limiting spring 73 limits the sliding block 72, so that there is a gap between the sliding block 72 and the slider 511. The elastic force of the limiting spring 73 is less than the elastic force of the return spring 66. In the initial state, neither the connecting spring 52 nor the limiting spring 73 is subjected to external force. The plug plate 53 is plugged into the sleeve plate 51, and the hinge rod 71 is inclined.

[0037] Reference Figure 2 and Figure 4 The door frame 1 is provided with a locking assembly 8 to limit the telescopic plate 5 and the sliding block 72. The locking assembly 8 includes screws 82 threadedly connected to the inner top surface and inner bottom surface of the door frame 1. One end of each screw 82 extends into the cavity 12. When installing the inflatable sealing ring 3, the operator first rotates the two screws 82 so that the end face of the screw 82 located in the cavity 12 does not protrude from the corresponding cavity wall of the cavity 12.

[0038] In the initial state, the mating plate 32 is located in the cavity 12, the rigid plate 4 is located in the groove 11, and the rack 61 is partially located in the cavity 12. The rack 61 meshes with the gear 63. As the operator pushes the inflatable sealing ring 3 into the groove 11, the rack 61 drives the gear 63 and the rope winding wheel to rotate, causing the pull rope 65 to be retracted and wound onto the rope winding wheel. While the pull rope 65 is being retracted and wound, it pulls the sliding block 72 to move closer to the slider 511. The movement of the slider 511 stretches the limit spring 73.

[0039] The sliding block 72 moves and drives the corresponding end of the hinge rod 71 to move, causing the upper end of the hinge rod 71 to drive the plug plate 53 to move. The sliding plate moves out of the groove of the sleeve plate 51, and at the same time, the plug plate 53 stretches the connecting spring 52. When the limit spring 73 is compressed to its limit, the distance between the surfaces of the two plug plates 53 that are close to each other is less than the distance between the surfaces of the two mating plates 32 that are far apart. As the pull rope 65 continues to wind and retract, the pull rope 65 drives the sliding block 72, the slider 511 and the telescopic plate 5 to move, causing the telescopic plate 5 to move away from the door panel 2. The slider 511 moves and compresses the reset spring 66.

[0040] When the rigid plate 4 contacts the groove wall corresponding to the groove 11, the sliding block 72 moves to the side where the bolt is away from the door panel 2. At this time, the operator rotates the bolt, causing the bolt to gradually protrude into the cavity 12. The bolt limits the sliding block 72, preventing the return spring 66 and the limit spring 73 from restoring their deformation, thereby preventing the slider 511 and the sliding block 72 from moving and resetting. This allows the telescopic plate 5 to limit the mating plate 32 and the connecting block 31, which can fix the inflatable sealing ring 3 and reduce the occurrence of the inflatable sealing ring 3 detaching from the groove 11.

[0041] After closing the door panel 2, the operator controls the inflation of the air sealing ring 3, so that the air sealing ring 3 abuts against the groove 11 of the door frame 1 and the door panel 2, which can seal the gap between the door frame 1 and the door panel 2, making the allowable fit error range of the contact surface between the door panel 2 and the door frame 1 wider, thereby reducing the processing requirements of the contact surface between the door frame 1 and the door, and reducing the processing cost of the carbon fiber box.

[0042] Because the inflatable sealing ring 3 is used frequently, it is prone to wear. When the inflatable sealing ring 3 needs to be replaced, the operator rotates the screw 82 to move the screw 82 downward. When the end of the screw 82 located in the cavity 12 moves to a position lower than the cavity wall corresponding to the cavity 12, the return spring 66 and the limit spring 73 restore their deformation. The return spring 66 restores its deformation and pushes the telescopic plate 5 to move closer to the door panel 2. The limit spring 73 restores its deformation and pushes the sliding block 72 to move away from the slider 511. At the same time, the connecting spring 52 restores its deformation and pulls the plug plate 53 into the groove of the sleeve plate 51, so that the distance between the two plug plates 53 gradually increases.

[0043] When both the reset spring 66 and the limit spring 73 return to their initial state, the telescopic plate 5 returns to its initial position. The distance between the surfaces of the two plug plates 53 that are close to each other is greater than the distance between the surfaces of the two mating plates 32 that are far apart from each other. At this time, the operator can easily pull the inflatable sealing ring 3 out of the groove 11 and remove the inflatable sealing ring 3 from the groove 11, thus making it convenient for the operator to replace the inflatable sealing ring 3.

[0044] The implementation principle of a carbon fiber box sealing structure in this application embodiment is as follows: The operator puts the inflatable sealing ring 3 into the groove 11 and pushes the inflatable sealing ring 3 into the groove 11. The inflatable sealing ring 3 drives the rotating rope wheel 64 to rotate through the rack 61. The rotating rope wheel 64 rotates and winds the pull rope 65 back. The pull rope 65 pulls the sliding block 72 to move, causing the hinge rod 71 to rotate. The hinge rod 71 pushes the plug plate 53 to move out of the sleeve plate 51. When the rigid plate 4 moves into place, the screw 82 is turned. The screw 82 limits the sliding block 72.

[0045] When the door panel 2 is closed, the inflatable sealing ring 3 contacts the door panel 2, sealing the gap between the door panel 2 and the door frame 1. When it is necessary to remove the inflatable sealing ring 3, the screw 82 is turned to release the limit on the sliding block 72, and the return spring 66 and the limit spring 73 restore their deformation, causing the telescopic plate 5 and the rigid plate 4 to move to their initial positions. When the telescopic plate 5 and the rigid plate 4 return to their initial positions, the operator pulls the inflatable sealing ring 3 out of the groove 11.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
