Description

Technical Field

[0001] This application relates to the field of fireproof sealing device technology, and more specifically, to a modular cable fireproof sealing device. Background Technology

[0002] During cable laying, when cables need to pass through walls, floors, firewalls, etc., holes usually need to be made in these locations to allow the cables to pass through. After the cables pass through the holes, the gaps in the holes need to be sealed, which requires the use of fireproof sealing devices.

[0003] In existing technologies, cable fire-stopping devices typically employ a frame with grooves on the left and right side walls and corresponding locking slots at the top. Fire-stopping modules have sliders at both ends that can engage with the corresponding grooves. During installation within the frame, the modules are sequentially inserted using the locking slots at the top. A clamping component at the top of the frame then presses the fire-stopping module firmly into place after the cable is threaded through it. However, in practical use, fire-stopping modules are prone to damage over time, requiring replacement. Currently, replacement necessitates disassembling the clamping component and the damaged module sequentially, leading to cumbersome operation and requiring the removal of numerous modules and clamping components. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this application is to provide a modular cable fireproof sealing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] A modular cable fireproof sealing device includes a frame and a plurality of fireproof sealing modules sequentially pressed into the frame. The inner sidewalls of the frame are provided with grooves along their height direction. The two ends of the fireproof sealing modules are provided with sliders that slide in the corresponding grooves. The fireproof sealing modules can be spliced ​​together. The frame at the top is provided with a pressing component for pressing the plurality of fireproof sealing modules.

[0007] The front side of the frame and both sides are provided with mounting grooves along its height direction. The mounting grooves are provided with several slots corresponding to the sliders, and the mounting grooves are provided with blocking blocks for sealing the slots.

[0008] Preferably, the front side of the frame and the upper part of the frame are provided with a snap-fit ​​groove for connecting the slide;

[0009] The press-fitting component includes a press-fitting block. Both ends of the press-fitting block are provided with snap-fitting blocks that snap into corresponding snap-fitting grooves and sliding grooves. The press-fitting block has a cavity, and the cavity is provided with opposing clamping elements. The cavity is also provided with a driving element, which is used to drive the opposing clamping elements to extend through the upper and lower sides of the press-fitting block.

[0010] Preferably, the clamping component includes a sliding plate that slides within the cavity and a protrusion that extends through the corresponding side of the pressing block. A mounting plate is fixedly mounted on the corresponding sliding plate within the cavity. A mounting rod that passes through the corresponding mounting plate is mounted on the sliding plate. A nut is threaded to the end of the mounting rod. A spring is sleeved on the mounting rod located between the mounting plate and the nut. The spring is used to push the sliding plate to retract the protrusion into the pressing block.

[0011] Preferably, the driving component includes driving blocks disposed on opposite sides of the slide plate, with guide surfaces disposed between opposite ends of the driving blocks. The driving component also includes a top block slidably disposed in the cavity, with a pressing surface on the side wall of the top block that cooperates with the corresponding guide surface. The top block moves toward the driving block, causing the pressing surface to press the guide surface so that the slide plates move away from each other.

[0012] Preferably, the drive component also includes a hand-tightening bolt that extends through the threaded press block into the cavity, with the through end of the hand-tightening bolt rotatably connected to the top block.

[0013] Preferably, the pressing block is provided with a handle on the front side.

[0014] Preferably, the frame includes opposing vertical beams and horizontal beams, with the horizontal beams connected to the upper and lower ends of the opposing vertical beams by bolts to form the frame.

[0015] Preferably, the fireproof sealing module includes several fireproof sealing units that are spliced ​​together. Each fireproof sealing unit includes an upper locking block and a lower locking block that are connected to each other, and a matching semi-locking groove is provided between the upper locking block and the lower locking block.

[0016] Compared with the prior art, the beneficial effects of this application are:

[0017] This application eliminates the need for sequential disassembly of the fireproof sealing module within the frame by releasing the pressure fittings. Then, the corresponding blocking blocks in the mounting slots on both sides of the damaged area are removed. The damaged fireproof sealing module is then removed from the frame through the slot, replaced with a new fireproof sealing module, and finally the pressure fittings are tightened again to secure the fireproof sealing modules. Compared to existing methods that require sequentially removing the fireproof sealing modules and pressure fittings above the damaged area for replacement, this application eliminates the need for sequential disassembly of the fireproof sealing modules, allowing for more convenient replacement of the fireproof sealing module at the damaged location.

[0031] To further understand the content of this application, a detailed description of this application will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of this application.

[0032] The following is in conjunction with the appendix Figures 1-6 This embodiment will be described in further detail.

[0033] like Figures 1-6As shown, a modular cable fireproof sealing device in this embodiment includes a frame 10 and a plurality of fireproof sealing modules 20 sequentially pressed into the frame 10. The inner sidewalls of the frame 10 are provided with grooves 201 along their height direction. The two ends of the fireproof sealing module 20 are provided with sliders 601 that slide in the corresponding grooves 201. The fireproof sealing modules 20 can be spliced ​​together. The frame 10 at the top is provided with a pressing component 30 for pressing the plurality of fireproof sealing modules 20.

[0034] In this embodiment, to facilitate the assembly of the frame 10, the frame 10 includes opposing vertical beams 110 and horizontal beams 120. The horizontal beams 120 are bolted to the upper and lower ends of the opposing vertical beams 110 to form the frame 10. The sliding grooves 201 are provided on the opposing sides of the vertical beams 110 along the extension direction of the vertical beams 110. The fireproof sealing module 20 can be installed in the frame 10 by using the sliders 601 at both ends of the fireproof sealing module 20 to engage with the corresponding sliding grooves 201.

[0035] In this embodiment, the fireproof sealing device is used in practice by making through holes in the wall for the frame 10 to be installed, depending on the location where the cable passes through the wall. The frame 10 and the fireproof sealing module 20 are both made of fireproof materials to give the fireproof sealing device better fire resistance.

[0036] In this embodiment, in order to better achieve the sequential pressing of the fireproof sealing module 20 within the frame 10, combined with Figure 2 As shown, in this embodiment, a snap-fit ​​groove 204 communicating with the slide groove 201 is provided on the front side and at the top of the frame 10. Therefore, after the frame 10 is assembled, the sliders 601 at both ends of the fireproof sealing module 20 can slide into the slide groove 201 through the snap-fit ​​groove 204 and slide along the slide groove 201 to the bottom of the frame 10, thereby enabling the rapid installation of several fireproof sealing modules 20 in the frame 10.

[0037] Combination Figure 6 As shown, in this embodiment, the fireproof sealing module 20 includes several fireproof sealing units 600 that are spliced ​​together. The slider 601 is disposed on the side wall of the fireproof sealing unit 600 at both ends. The fireproof sealing unit 600 includes an upper locking block 610 and a lower locking block 620 that are connected to each other. There is a matching half-slot between the upper locking block 610 and the lower locking block 620. That is, when the upper locking block 610 and the lower locking block 620 are spliced ​​together to form the fireproof sealing unit 600, the two half-slots are also spliced ​​together to form a slot 602 for the cable to pass through. Therefore, when the fireproof sealing device is installed on the wall and the cable passes through the corresponding slot 602, the pressing component 30 presses the several fireproof sealing modules 20 below to improve the sealing effect of the fireproof sealing device.

[0038] Specifically, in order to improve the sealing performance between adjacent fireproof sealing modules 20 during press-fitting, in this embodiment, a sealing plate 40 is provided between adjacent fireproof sealing modules 20, wherein the sealing plate 40 is made of rubber material;

[0039] Specifically, to prevent sliding misalignment between the spliced ​​fireproof sealing units 600, which would affect the sealing effect of the fireproof sealing module 20, combined with Figure 6 As shown, in this embodiment, the fireproof sealing unit 600 has matching limiting grooves 603 or limiting blocks 604 on both side walls. This allows the limiting blocks 604 between adjacent fireproof sealing units 600 to engage with the corresponding limiting grooves 603 when splicing several fireproof sealing units 600, thereby limiting the fireproof sealing units 600 to prevent sliding misalignment between adjacent fireproof sealing units 600 when they are pressed into the frame 10.

[0040] It should be noted that multiple sealing rings and a plug embedded in the innermost sealing ring are sequentially fitted inside the slot 602. This allows the plug and the corresponding number of sealing rings to be removed according to the diameter of the cable during actual use, so that the cable can pass through the sealing ring. At this time, the sealing ring is pressed against the side wall of the slot 602 and the outer surface of the cable by the pressing component 30, thereby ensuring the sealing of the cable passage. At the same time, it enables the fireproof sealing device to adapt to cables of different diameters, improving its applicability.

[0041] In this embodiment, the front side of the frame 10 and the two sides are provided with mounting grooves 202 along its height direction. The mounting grooves 202 are provided with a plurality of slots 203 corresponding to the slider 601. The mounting grooves 202 are provided with blocking blocks 210 for sealing the slots 203 corresponding to the slots 203.

[0042] In practical use, the fireproof sealing module 20 of this embodiment is prone to damage due to prolonged use and needs replacement. In this embodiment, by setting up the mounting groove 202, slot 203, and blocking block 210, firstly, the pressure of the pressing component 30 on the fireproof sealing module 20 inside the frame 10 is released. Then, according to the location of the damaged fireproof sealing module 20, the blocking block 210 at the corresponding position in the mounting grooves 202 on both sides is removed to open the slot 203. Finally, the block above the damaged position is removed manually or using a lifting device. The fireproof sealing module 20 is lifted up, and the damaged fireproof sealing module 20 is removed from the frame 10 through the slot 203. After replacing it with a new fireproof sealing module 20, the pressing component 30 is pressed down on the fireproof sealing module 20 again. Compared with the existing method that requires removing the fireproof sealing module 20 and the pressing component 30 above the damaged position from the top to replace the fireproof sealing module 20, this embodiment does not require disassembling the fireproof sealing module 20 in sequence, and can replace the fireproof sealing module 20 at the damaged position more conveniently.

[0043] Combination Figures 3-5 As shown, in this embodiment, the pressing component 30 includes a pressing block 310. Both ends of the pressing block 310 are provided with snap-fit ​​blocks 311 that snap into the corresponding snap-fit ​​grooves 204 and sliding grooves 201. The pressing block 310 is provided with a cavity 401. The cavity 401 is provided with a corresponding pressing component 320. In the initial state, the pressing component 320 is retracted into the pressing block 310, which facilitates the assembly and disassembly of the pressing block 310 in the frame 10. The cavity 401 is also provided with a driving component, which is used to drive the corresponding pressing component 320 to extend through the upper and lower sides of the pressing block 310.

[0044] In actual use, the snap-fit ​​block 311 is aligned with the corresponding snap-fit ​​slot 204 and slid in to achieve the insertion and installation of the press-fit block 310 in the frame 10. At this time, the pressing members 320 on the upper and lower sides of the cavity 401 are driven to extend synchronously by the driving member, so that the upper pressing member 320 abuts against the inner top wall of the frame 10 and the lower pressing member 320 abuts against the uppermost fireproof sealing module 20, thereby realizing the press-fit of the press-fit member 30 to the several fireproof sealing modules 20 in the frame 10.

[0045] In order to improve the sealing between the lower pressing member 320 and the uppermost fireproof sealing module 20, a sealing plate 40 is also provided between them in actual use.

[0046] Specifically, in order to facilitate the operator to assemble and disassemble the pressing block 310 within the frame 10, in this embodiment, a handle 312 is provided on the front side of the pressing block 310, so that the operator can better carry and insert the pressing block 310 through the handle 312.

[0047] It should be noted that, in order to facilitate the installation of the clamping component 320 and the driving component in the cavity 401, in this embodiment, the opening of the cavity 401 is set towards the rear side of the pressing block 310, and a removable back plate 400 is provided on its rear side by screws.

[0048] In this embodiment, the clamping member 320 includes a sliding plate 410 slidably disposed within the cavity 401 and a protrusion 411 extending through the corresponding side of the pressing block 310. The sidewall of the sliding plate 410 slidably fits against the sidewall of the cavity 401. The protrusion 411 is disposed along the extending direction of the sliding plate 410 and integrally formed on the corresponding side of the sliding plate 410. A mounting plate 420 is fixedly disposed within the cavity 401 corresponding to the sliding plate 410. The mounting plate 420 is disposed within the cavity 401 between the upper and lower sliding plates 410, and the mounting plate at the upper and lower positions... The mounting plates 420 are staggered. The sliding plate 410 is provided with a mounting rod 412 that passes through the corresponding mounting plate 420. The end of the mounting rod 412 is threaded with a nut 413. A spring 430 is sleeved on the mounting rod 412 located between the mounting plate 420 and the nut 413. One end of the spring 430 abuts against the mounting plate 420 and the other end abuts against the nut 413, so that the spring 430 pushes the sliding plate 410 to drive the protrusion 411 to retract into the pressing block 310, thereby realizing that in the initial state, the pressing member 320 is in the state of retracting into the pressing block 310.

[0049] In this embodiment, the driving component includes driving blocks 414 disposed on opposite sides of the slide plate 410. The opposite ends of the driving blocks 414 are provided with guide surfaces. In actual use, the adjacent guide surfaces are arranged in a V-shape. The driving component also includes a top block 440 slidably disposed in the cavity 401. The side wall of the top block 440 is provided with a pressing surface 501 that cooperates with the corresponding guide surface. That is, the top block 440 is disposed in the cavity 401 between the driving blocks 414 along the extension direction of the slide plate 410 so that the pressing surface 501 always fits the corresponding guide surface. At this time, the top block 440 moves toward the driving block 414 to drive the pressing surface 501 to press the guide surface so that the slide plates 410 move away from each other, thereby causing the protrusion 411 to extend out of the upper and lower sides of the pressing block 310.

[0050] In this embodiment, in order to facilitate the operator to drive the top block 440 to move within the cavity 401 and to achieve the telescopic control of the clamping member 320, the driving member further includes a hand-tightening bolt 330 that extends into the cavity 401 through the front side of the pressing block 310. The through end of the hand-tightening bolt 330 is rotatably connected to the top block 440. Specifically, the through end of the hand-tightening bolt 330 is rotatably mounted on the side of the top block 440 through a bearing. Thus, turning the hand-tightening bolt 330 can drive the top block 440 to move toward or away from the driving block 414 to achieve the telescopic control of the protrusion 411.

[0051] Specifically, in order to limit the movement of the top block 440 within the cavity 401 so that it can be driven to move towards or away from the drive block 414 by the hand-tightening bolt 330, in this embodiment, a guide rod 415 is provided in the cavity 401, passing through the corresponding end of the top block 440. The guide rod 415 is used to limit the movement of the top block 440, so as to achieve smooth movement of the top block 440 within the cavity 401.

[0052] In summary, the above description is only a preferred embodiment of this application. All equivalent changes and modifications made within the scope of this application should be covered by this application.
