Description

Technical Field

[0001] This application relates to the technical field of marine pipeline support equipment, and in particular to a marine fiberglass pipe support. Background Technology

[0002] Currently, fiberglass pipes are widely used in ship ballast water systems, fire protection systems, cooling water systems, and marine observation equipment pipeline systems due to their excellent properties such as light weight, high strength, and resistance to seawater corrosion. However, the low stiffness, low surface hardness, and poor impact toughness of fiberglass pipes place special requirements on support devices. Existing ship pipeline supports mostly follow the design of traditional metal pipe supports, which has problems such as rigid clamping of pipes that can easily damage the pipe wall, lack of vibration reduction and isolation design, inability to adapt to hull deformation, and inconvenience of installation and maintenance of welded structures in narrow cabins. In particular, shipborne hydrological and meteorological observation sensors and their supporting equipment and systems usually need to complete tasks such as sample transportation and cooling through fiberglass pipeline systems carried by ships and mobile observation platforms such as buoys. The pipeline supports are in a harsh environment of high salt spray and continuous vibration for a long time.

[0003] Regarding the aforementioned technologies, there is a Chinese patent for a fiberglass pipe support with the existing authorization announcement number CN222458638U. It uses a clamp assembly in conjunction with an arc-shaped protective tile to fix the pipe. However, the pipe clamp assembly is fixed in position and cannot achieve universal clamping of straight and right-angle pipes by a single support, making it difficult to meet the high reliability requirements of the support device under complex sea conditions.

[0004] Therefore, there is an urgent need for a marine fiberglass pipe support that can reliably support pipelines, effectively protect pipe walls, flexibly adapt to both straight and right-angle pipes, and is easy to install and maintain. Summary of the Invention

[0005] The purpose of this application is to provide a marine fiberglass pipe support to solve the problems in the prior art.

[0006] The technical solution of the marine fiberglass pipe support provided in this application is as follows: it includes a steel base, and side seats are fixed on both the left and right sides of the steel base. The side seats are locked to the bottom of the hull by locking bolts. A first clamp is provided on the front side of the upper end of the steel base, and a second clamp is provided on the rear side of the first clamp. It also includes a pipe adaptation device installed on one side of the upper end of the steel base and connected to the lower end of the second clamp.

[0007] By adopting the above technical solution, the steel frame base is used as the basic load-bearing component and is firmly locked to the bottom of the ship's cabin by the side seat and the locking bolt. The first clamp is fixed to the front side of the upper end of the steel frame base to clamp the straight section of fiberglass pipe. The pipe adaptation device is used to drive the second clamp to switch between the straight pipe clamping position and the right-angle pipe clamping position, thereby realizing the universal clamping of both straight pipe and right-angle pipe by a single support, improving the adaptability and flexibility of the support.

[0008] Preferably, the pipe adaptation device includes a screw rod, which is rotatably installed inside the steel profile seat. The screw rod is externally threaded with a movable folding assembly, which is slidably connected to the inside of the steel profile seat. The front side of the movable folding assembly is connected to a first locking assembly that engages with the inside of the steel profile seat, and the rear side of the movable folding assembly is connected to a telescopic assembly. A second locking assembly is provided on one side inside the telescopic assembly.

[0009] By adopting the above technical solution, the rotating screw can drive the movable folding assembly to slide forward along the inside of the steel frame seat in advance. During this forward movement, the transmission second clamping component is pre-extended and flipped, and then slides backward a certain distance, so that the flipped second clamping component and the first clamping component form a clamping distance that is adapted to the right-angle pipe bend section, improving the adaptability to the right-angle pipe clamping position and realizing the conversion of the second clamping component from the straight pipe clamping posture to the right-angle pipe clamping posture; the first locking assembly is used to lock the moving plate relative to the steel frame seat after the movable folding assembly slides into place, preventing it from sliding down in the working state; the telescopic assembly is used to adjust the vertical height of the second clamping component to adapt to different pipe diameters and installation positions; the second locking assembly is used to lock the rotating arm relative to the moving plate after the folding action is completed, ensuring the structural rigidity and reliability in the right-angle pipe clamping state.

[0010] Preferably, the movable folding assembly includes a base plate, which is slidably embedded inside a steel seat and is threadedly connected to a screw. Side plates are fixed on both sides of the base plate, and each side plate has a transmission groove. A roller is embedded in the transmission groove and is rotatably connected to one end of a rotating arm. The side of the rotating arm away from the roller is connected to a telescopic assembly via a shaft. A locking plate is connected to the shaft connecting the rotating arm and the telescopic assembly, and the locking plate is locked to the external bolts on both sides of the movable plate. A first locking assembly is connected to the front of the movable plate. A first limiting shaft is fixed to the external side of one side of the rotating arm, and a second limiting shaft is fixed to the external side of the locking plate.

[0011] By adopting the above technical solution, when the screw is rotated, the base plate drives the side plate to slide along the inside of the steel seat from front to back. During the sliding process of the side plate, the transmission groove guides the roller, forcing the roller to move along the trajectory of the transmission groove, thereby driving the rotating arm to rotate counterclockwise around the shaft, thus realizing the flipping drive of the telescopic component and the second clamp; at the same time, after the rotating arm rotates to the position, it will drive the moving plate to move synchronously, and the first limit shaft abuts against the second limit shaft when the rotating arm rotates to the limit position, limiting the rotation angle range of the rotating arm and ensuring that the rotating arm is accurately positioned in the right-angle tube working position.

[0012] Preferably, the first locking assembly includes a plug-in shaft, one end of which is connected to a movable plate, and the other side of the plug-in shaft is inserted into the steel base and connected to a connecting block. The connecting block is slidably built into a mating groove, which is opened inside the steel base. A movable frame is movably installed inside the connecting block. A first spring is connected to the top of the movable frame, and a ball is rotatably connected to the bottom of the movable frame. The ball is limited and embedded in a locking groove, which is opened on both sides of the bottom of the mating groove.

[0013] By adopting the above technical solution, when the moving plate moves backward with the side plate, it simultaneously drives the plug shaft and connecting block to slide along the docking groove. When the connecting block slides to the position of the locking slot on one side, the first spring pushes the movable frame downward to make the ball embedded in the locking slot, thereby realizing the automatic locking of the connecting block and the steel seat, and realizing the rapid positioning and reliable locking of the moving folding assembly in the straight tube working position and the right-angle tube working position.

[0014] Preferably, the telescopic assembly includes a first connecting plate, one end of which is connected to and rotates with the two rotating arms on both sides. Positioning tubes are vertically connected to two points inside the first connecting plate, and vertical tubes are vertically inserted into the positioning tubes on each side. A second connecting plate is connected to the top of the vertical tubes on both sides, and the outside of the second connecting plate is connected to a second clamping member. A telescopic plate is fixed to the middle of one side of the second connecting plate, and a snap-fit ​​member is connected to the outside of the telescopic plate. An elastic strip is elastically abutted against one side of the snap-fit ​​member, and an unlocking groove is provided on the outside of the snap-fit ​​member. A snap-fit ​​shaft is connected to the end of the snap-fit ​​member away from the elastic strip. The telescopic plate is vertically inserted into the guide plate, and the guide plate is vertically installed inside the first connecting plate. Guide grooves are provided in the middle of the outer walls on both sides of the guide plate. A first switching groove is connected to the bottom of the guide groove, and a second switching groove is connected to the top of the guide groove. A telescopic snap-fit ​​groove is vertically and equidistantly provided on one side between the first and second switching grooves, and the inside of the telescopic snap-fit ​​groove is engaged with the snap-fit ​​shaft.

[0015] By adopting the above technical solution, the first connecting plate rotates synchronously when the rotating arm rotates, and the positioning tube and the vertical tube form a telescopic guide structure, allowing the second connecting plate and the second clamp to be adjusted vertically. The telescopic plate slides vertically along the guide plate, and the elastic strip pushes the clamp to keep the clamp shaft pressed against the guide plate. When the telescopic plate slides to the required height, the clamp shaft automatically engages in the telescopic slot of the corresponding height to achieve height locking. When the height needs to be adjusted, the second connecting plate is pulled further, causing the clamp to overcome the elastic force of the elastic strip and move out of the telescopic slot. In this way, the clamp shaft exits the telescopic slot, and the height of the second connecting plate can be freely adjusted. When the clamp moves into the first or second switching slot, the elastic strip will intermittently lock with the unlocking slot, allowing the second clamp to be quickly positioned in both working modes.

[0016] Preferably, the second locking assembly includes a swing arm, which is rotatably mounted inside the first connecting plate. The upper end of the swing arm has an inner tube, and a connecting shaft is inserted into the inner tube. A second spring for elastic pull-down is installed at the insertion end of the connecting shaft. A lever is connected to the top of the connecting shaft, and the lever extends outward into a limiting slot. The limiting slot is located on the outer side of one end of the first connecting plate. A mating strip is rotatably connected to the bottom of the swing arm. A locking shaft is rotatably connected to the end of the mating strip away from the swing arm. The locking shaft is externally inserted into and locked to the moving plate.

[0017] By adopting the above technical solution, after the rotating arm is rotated into position, the lever is moved to slide along the limiting slot. The lever drives the swing arm to rotate around the inside of the first connecting plate through the connecting shaft. When the swing arm rotates, it pushes the locking shaft forward through the connecting bar, so that the locking shaft is inserted into the corresponding locking hole of the moving plate, locking the rotating arm and the moving plate relative to each other. The second spring applies a downward elastic force to the connecting shaft, so that the lever remains locked at the end of the limiting slot when there is no external force, preventing the lever from being accidentally dislodged due to ship vibration, and ensuring reliable locking between the rotating arm and the moving plate under the right-angle tube clamping state.

[0018] Preferably, the transmission groove is opened in a reverse Z-shaped groove shape, and the transmission groove moves backward to conduct the rotating arm to rotate counterclockwise by 90°.

[0019] By adopting the above technical solution, that is, when the bottom plate moves backward, the roller is located in the top horizontal section of the transmission groove before the adjustment activity begins; during the adjustment process, the transmission groove moves backward with the side plate, and the roller slides from the top horizontal section through the inclined section to the bottom horizontal section relative to the transmission groove, thereby realizing the counterclockwise 90° rotation of the rotating arm, so that the second clamping part flips from the horizontal straight pipe clamping posture to the vertical right-angle pipe clamping posture.

[0020] Preferably, the lower end of the elastic strip is bent at a right angle, and the bottom right-angled end of the elastic strip slides against the locking outer side of the snap-fit ​​component.

[0021] By adopting the above technical solution, the right-angle bend at the lower end of the elastic strip forms a stable elastic contact surface with the outer side of the snap-fit ​​component. The right-angle bend structure increases the contact area between the elastic strip and the snap-fit ​​component, preventing the elastic strip from wearing or shifting due to point contact during long-term use. This ensures that the direction of the elastic strip's thrust on the snap-fit ​​component is always perpendicular to the outer wall of the snap-fit ​​component. When the second connecting plate is lowered and reset, the snap-fit ​​component moves upward into the second switching slot. At this time, the right-angle bend at the bottom of the elastic strip will snap into the unlocking slot, ensuring that when the snap-fit ​​component moves downward toward the first switching slot, the snap-fit ​​component does not drive the snap-fit ​​shaft to lock with the telescopic snap-fit ​​slot. This improves the stability of the telescopic component's adjustment process, allowing it to be stably embedded in the telescopic snap-fit ​​slot even under vibration.

[0022] Preferably, the first switching slot and the second switching slot are staggered in the vertical direction, with the first switching slot located on the bottom left side of the guide slot and the second switching slot located on the top right side of the guide slot.

[0023] By adopting the above technical solution, namely the staggered distribution of the first switching groove and the second switching groove, when the locking component performs telescopic transmission, it performs a downward switching action along the second switching groove and an upward locking action along the first switching groove; this staggered layout enables the telescopic plate to have a flexible height adjustment effect.

[0024] Preferably, the limiting slot is formed in a semi-circular groove shape, and the limiting end of the limiting slot is bent and extended.

[0025] By adopting the above technical solution, the semi-circular groove provides a smooth sliding path for the lever, making it easy for the operator to slide the lever along the arc with one hand; the limiting end is bent and extended to form a locking notch, which naturally locks when the lever slides into the bent extension section. Combined with the elastic pull of the second spring, the lever will not automatically disengage from the locking position when there is no external force, ensuring the locking reliability of the second locking assembly under ship vibration conditions.

[0026] Preferably, the lever is movably embedded inside the swing arm lock, and the lever extends to the outer end of the limiting slot to support manual operation.

[0027] By adopting the above technical solution, where the extended end of the lever extends to the outside of the limiting slot, the operator can directly and manually move the lever to perform locking and unlocking operations without the need for tools. At the same time, the extended end provides a clear visual indication of the locked position, making it easy for the operator to visually confirm whether the second locking component is currently in the locked or unlocked state.

[0028] In summary, this application includes the following beneficial technical effects: 1. This application uses a steel base, a first clamp, and a second clamp. The steel base serves as the basic load-bearing component and is securely locked to the bottom of the ship's hold by side seats and bolts, providing a stable installation foundation for the entire support. The first clamp is fixed to the front of the upper end of the steel base, and the second clamp is supported on the rear of the upper end of the steel base by a pipe adaptation device. In the initial state, the two clamps maintain the same horizontal height and form a straight pipe clamping distance. The first clamp and the second clamp cooperate to clamp the straight pipe section of fiberglass in a horizontal posture, achieving stable support and reliable fixation of the support for the straight pipe. The structure is simple and has a strong load-bearing capacity.

[0029] 2. This application incorporates a pipe adaptation device, where rotating the screw drives the movable folding assembly to slide forward along the interior of the steel base. During this forward movement, the transmission second clamping member extends and flips, then slides backward a distance, creating a clamping distance between the flipped second clamping member and the first clamping member that is adapted to the right-angle pipe bend. This allows for flexible conversion of the second clamping member from a straight pipe clamping posture to a right-angle pipe clamping posture. Simultaneously, the telescopic assembly can adjust the vertical height of the second clamping member to adapt to different pipe diameters and installation positions, enabling a single support to universally clamp both straight and right-angle pipes, thus solving the problem of poor adaptability of existing supports to different pipe types.

[0030] 3. This application uses a movable folding assembly. When the screw is rotated, the base plate drives the side plate to slide forward and backward along the inside of the steel seat. During the sliding process, the reverse Z-shaped transmission groove inside the side plate guides the roller. The roller first slides along the top horizontal section of the transmission groove, then descends along the oblique transition section, and finally positions itself along the bottom horizontal section. This specific trajectory converts the straight backward movement of the base plate into the displacement of the roller in the groove, thereby driving the rotating arm to achieve a precise counterclockwise 90° rotation around the shaft. This allows the second clamp to smoothly flip from a horizontal straight tube clamping posture to a vertical right-angle tube clamping posture. At the same time, the first limiting shaft abuts against the second limiting shaft when the rotating arm rotates to its limit position, precisely limiting the flipping angle. The transmission is smooth and the angular displacement is precisely controllable.

[0031] 4. This application sets up a first locking component, that is, when the moving plate moves backward with the side plate to the designated position, the plug shaft and the connecting block slide synchronously along the docking groove to the position of the locking slot on one side. At this time, the first spring pushes the movable frame downward to make the ball embed into the locking slot, thereby realizing the automatic locking of the connecting block and the steel seat, thus fixing the entire moving folding component relative to the steel seat, realizing the reliable locking of the moving folding component in the right-angle tube working position, effectively avoiding accidental slippage in the working state, and ensuring structural stability.

[0032] 5. This application uses a telescopic assembly, namely a positioning tube and a vertical tube forming a telescopic guide structure, to allow the second connecting plate and the second clamp to be adjusted vertically. The telescopic plate slides vertically along the guide plate, and the elastic strip pushes the clamping component to keep the clamp shaft pressed against the guide plate. When the telescopic plate slides to the required height, the clamp shaft automatically engages in the corresponding telescopic groove to achieve height locking. When it needs to be lowered and reset, the clamping component drives the clamp shaft to move upward into the second switching groove. The unlocking groove and the right-angle bend at the bottom of the elastic strip lock the clamping component in a locked and stationary state. When it moves downward, the inclined surface at the entry end of the first switching groove automatically releases the lock, providing convenient preparation for subsequent telescopic locking. The adjustment process is stable and reliable.

[0033] 6. This application incorporates a second locking assembly. After the rotating arm rotates to its designated position, a lever is actuated to slide along the limiting slot. The lever, via a connecting shaft, drives the swing arm to rotate around the inside of the first connecting plate. As the swing arm rotates, the connecting strip pushes the locking shaft forward, allowing it to insert into the corresponding locking hole in the moving plate, thus locking the rotating arm and the moving plate together. This further enhances the support stability of the telescopic assembly after it flips over, ensuring the overall structure is rigidly reliable under the clamping state of the right-angle tube. The second spring applies a downward elastic force to the connecting shaft, keeping the lever locked at the end of the limiting slot when no external force is applied. This effectively prevents the lever from accidentally dislodging due to ship vibration, ensuring a durable and reliable lock. Attached Figure Description

Detailed Implementation

[0036] The following is in conjunction with the appendix Figure 1 -Appendix Figure 11 This application will be described in further detail below.

[0037] A marine fiberglass pipe support, reference Figure 1 It includes a steel base 1, with side seats 2 fixed on both the left and right sides of the steel base 1. The side seats 2 are locked to the bottom of the hull by bolts 3. A first clamp 4 is provided on the front side of the upper end of the steel base 1, and a second clamp 5 is provided on the rear side of the first clamp 4. It also includes a pipe adaptation device 6 installed on one side of the upper end of the steel base 1 and connected to the lower end of the second clamp 5.

[0038] Furthermore, the steel base 1, as the basic load-bearing component, is firmly locked to the bottom of the hull by the side seat 2 and the locking bolt 3. The first clamp 4 is fixed to the front side of the upper end of the steel base 1 to clamp the straight section of the fiberglass pipe. The pipe adaptation device 6 is used to drive the second clamp 5 to switch between the straight pipe clamping position and the right-angle pipe clamping position, thereby realizing the universal clamping of both straight pipe and right-angle pipe by a single support, improving the adaptability and flexibility of the support.

[0039] Both the first clamp 4 and the second clamp 5 have an elastic buffer layer made of polytetrafluoroethylene installed inside, and the surface of the elastic buffer layer is provided with anti-slip texture.

[0040] Reference Figure 2The pipe adaptation device 6 includes a screw 61, which is rotatably and longitudinally installed inside the steel base 1. A movable folding assembly 62 is threadedly connected to the outside of the screw 61, and the movable folding assembly 62 is slidably connected to the inside of the steel base 1 and slides back and forth therein. A first locking assembly 63 is connected to the front side of the movable folding assembly 62 and engages with the inside of the steel base 1. A telescopic assembly 64 is connected to the rear side of the movable folding assembly 62. When the telescopic assembly 64 is not flipped up with the movable folding assembly 62, it is in a straight pipe clamping state. When the telescopic assembly 64 is flipped up with the movable folding assembly 62, it is in a right-angle pipe clamping state. A second locking assembly 65 is provided on one side inside the telescopic assembly 64, and the second locking assembly 65 locks the telescopic assembly 64 when it is flipped up with the movable folding assembly 62, so that the telescopic assembly 64 is in a stable right-angle pipe clamping state when it is flipped up.

[0041] Furthermore, the rotating screw 61 can drive the movable folding assembly 62 to slide forward along the inside of the steel base 1. During this forward movement, the transmission second clamp 5 is pre-extended and flipped, and then slides backward a certain distance, so that the flipped second clamp 5 and the first clamp 4 form a clamping distance that is adapted to the right-angle pipe bend section, improving the adaptability to the right-angle pipe clamping position and realizing the conversion of the second clamp 5 from the straight pipe clamping posture to the right-angle pipe clamping posture; the first locking assembly 63 is used to lock the moving plate 627 relative to the steel base 1 after the movable folding assembly 62 slides into place, preventing it from sliding down in the working state; the telescopic assembly 64 is used to adjust the vertical height of the second clamp 5 to adapt to different pipe diameters and installation positions; the second locking assembly 65 is used to lock the rotating arm 625 relative to the moving plate 627 after the folding action is completed, ensuring the structural rigidity and reliability in the right-angle pipe clamping state.

[0042] Reference Figures 3-5The movable folding assembly 62 includes a base plate 621, which is slidably embedded inside the steel base 1 and externally threaded to the screw 61. Side plates 622 are fixed to both sides of the base plate 621, and each side plate 622 has a transmission groove 623 inside. Rollers 624 are embedded inside the transmission grooves 623 on both sides, and the rollers 624 are rotatably connected to the front end of the rotating arm 625. The side of the rotating arm 625 away from the rollers 624 is connected to the telescopic assembly 64 via a shaft. That is, when the rotating arm 625 rotates, the telescopic assembly 64 is simultaneously flipped and adjusted. The rotating arm 625 and the telescopic assembly... A locking plate 626 is connected to the shaft of component 64, and the locking plates 626 on both sides are locked to the external bolts at the left and right rear ends of the moving plate 627. This provides a stable support base for the synchronous flipping process of the rotating arm 625 and the telescopic component 64. Two first locking components 63 are connected to the front of the moving plate 627. A first limiting shaft 628 is fixed to the outside of one side of the rotating arm 625, and a second limiting shaft 629 is fixed to the outside of the locking plate 626. That is, when the rotating arm 625 flips counterclockwise, the first limiting shaft 628 and the second limiting shaft 629 cooperate to limit the rotation, ensuring the accuracy of the flipping angle of the telescopic component 64.

[0043] Furthermore, when the screw 61 is rotated, the base plate 621 drives the side plate 622 to slide along the inside of the steel seat 1 from front to back. During the sliding process of the side plate 622, the transmission groove 623 guides the roller 624, forcing the roller 624 to move along the trajectory of the transmission groove 623, thereby driving the rotating arm 625 to rotate counterclockwise around the shaft, thus realizing the flipping drive of the telescopic component 64 and the second clamp 5. At the same time, after the rotating arm 625 rotates to the position, it will drive the moving plate 627 to move synchronously. When the rotating arm 625 rotates to the limit position, the first limiting shaft 628 abuts against the second limiting shaft 629, limiting the rotation angle range of the rotating arm 625, ensuring that the rotating arm 625 is accurately positioned in the right-angle tube working position.

[0044] The transmission groove 623 is opened in the shape of a reverse Z-shaped groove, and the transmission groove 623 moves backward to conduction arm 625 to rotate 90° counterclockwise.

[0045] Furthermore, when the base plate 621 moves backward, before the adjustment begins, the roller 624 is located in the top horizontal section of the transmission groove 623. During the adjustment process, the transmission groove 623 moves backward with the side plate 622, and the roller 624 slides relative to the transmission groove 623 from the top horizontal section through the inclined section to the bottom horizontal section, thereby realizing the counterclockwise 90° rotation of the rotating arm 625, so that the second clamp 5 flips from the horizontal straight pipe clamping posture to the vertical right-angle pipe clamping posture.

[0046] Reference Figure 6The first locking assembly 63 includes a plug shaft 631, which is horizontally connected to the upper and lower ends of the left side of the movable plate 627. The left ends of both plug shafts 631 are slidably inserted into the steel base 1 and connected to a connecting block 632. The connecting block 632 is slidably built into the docking groove 633, which is opened on the upper and lower sides inside the steel base 1. A movable frame 634 is vertically mounted inside the connecting block 632. A first spring 635 is connected to the side of the movable frame 634 near the inner side of the connecting block 632, and a ball bearing 636 is slidably connected to the side of the movable frame 634 away from the inner side of the movable frame 634. The ball bearing 636 is limited and embedded in the locking groove 637, which is opened on both sides of the bottom of the docking groove 633.

[0047] Furthermore, when the movable plate 627 moves backward along with the side plate 622, it simultaneously drives the insertion shaft 631 and the connecting block 632 to slide synchronously along the docking groove 633. When the connecting block 632 slides to the position of the locking groove 637 on one side, the first spring 635 pushes the movable frame 634 downward to make the ball 636 embed into the locking groove 637, thereby realizing the automatic locking of the connecting block 632 and the steel base 1, and realizing the rapid positioning and reliable locking of the movable folding assembly 62 in the straight tube working position and the right-angle tube working position.

[0048] Reference Figures 7-9 The telescopic assembly 64 includes a first connecting plate 641, one end of which is connected to and rotates with the two rotating arms 625. Positioning tubes 642 are vertically connected to both sides of the first connecting plate 641, and vertical tubes 643 are vertically inserted into each positioning tube 642, forming a telescopic guide structure. A second connecting plate 644 is connected to the top of the two vertical tubes 643, and the outside of the second connecting plate 644 is connected to the second clamp 5. A telescopic plate 645 is fixed to the lower middle of the second connecting plate 644. A locking member 646 is rotatably connected to the lower end of the telescopic plate 645. An elastic strip 647 is elastically abutted against the left side of the locking member 646, and the upper end of the elastic strip 647 is fixedly connected to the telescopic plate 645. An unlocking groove 648 is provided on the upper side of the locking member 646, i.e., the elastic strip 647... When the lower end of 47 engages with the unlocking slot 648, the engaging member 646 is in a locked and stationary state and does not perform telescopic locking activities. The end of the engaging member 646 away from the elastic strip 647 is connected to the locking shaft 649. The telescopic plate 645 is vertically inserted into the guide plate 6410, and the guide plate 6410 is vertically installed in the middle of the first connecting plate 641. The guide grooves 6411 are opened in the middle of the outer walls on both the front and rear sides of the guide plate 6410. The bottom of the guide groove 6411 is connected to the first switching groove 6412, and the top of the guide groove 6411 is connected to the second switching groove 6414. The telescopic locking groove 6413 is vertically and equidistantly opened on the right side between the first switching groove 6412 and the second switching groove 6414, and the telescopic locking groove 6413 is engaged with the locking shaft 649.

[0049] Furthermore, when the rotating arm 625 rotates, it drives the first connecting plate 641 to rotate synchronously. The positioning tube 642 and the vertical tube 643 form a telescopic guide structure, allowing the second connecting plate 644 and the second clamp 5 to be adjusted vertically. The telescopic plate 645 slides vertically along the guide plate 6410, and the elastic strip 647 pushes the clamping member 646 to keep the clamping shaft 649 pressed against the guide plate 6410. When the telescopic plate 645 slides to the required height, the clamping shaft 649 automatically engages with the corresponding telescopic groove 64. The height is locked within 13. When the height needs to be adjusted, continue to pull the second connecting plate 644 so that the locking piece 646 overcomes the elastic force of the elastic strip 647 and moves outward from the telescopic slot 6413. In this way, the locking shaft 649 exits the telescopic slot 6413, and the height of the second connecting plate 644 can be freely adjusted. When the locking piece 646 moves into the first switching slot 6412 or the second switching slot 6414, the elastic strip 647 will intermittently lock with the unlocking slot 648, so that the second clamp piece 5 can be quickly positioned in both working modes.

[0050] The elastic strip 647 has a right-angle bend at its lower end, and the right-angle bend at the bottom of the elastic strip 647 slides against the locking outer side of the snap fastener 646.

[0051] Furthermore, the right-angle bend at the lower end of the elastic strip 647 forms a stable elastic contact surface with the outer side of the snap-fit ​​component 646. The right-angle bend structure increases the contact area between the elastic strip 647 and the snap-fit ​​component 646, preventing the elastic strip 647 from wearing or shifting due to point contact during long-term use. This ensures that the direction of the thrust of the elastic strip 647 on the snap-fit ​​component 646 is always perpendicular to the outer wall of the snap-fit ​​component 646. When the second connecting plate 644 is lowered and reset, the snap-fit ​​component 646 moves upward into the second switching groove 6414. At this time, the right-angle bend at the bottom of the elastic strip 647 will be engaged in the unlocking groove 648. This ensures that when the snap-fit ​​component 646 moves downward toward the first switching groove 6412, the snap-fit ​​component 646 does not drive the snap-fit ​​shaft 649 to lock with the telescopic snap-fit ​​groove 6413. This improves the stability of the telescopic component 64 during adjustment, allowing it to be stably embedded in the telescopic snap-fit ​​groove 6413 even under vibration.

[0052] The first switching slot 6412 and the second switching slot 6414 are staggered in the vertical direction, with the first switching slot 6412 located on the bottom left side of the guide slot 6411 and the second switching slot 6414 located on the top right side of the guide slot 6411.

[0053] Furthermore, the staggered distribution of the first switching groove 6412 and the second switching groove 6414 allows the latching member 646 to perform a downward switching action along the second switching groove 6414 and an upward locking action along the first switching groove 6412 when it is telescopically transmitting; this staggered layout allows the telescopic plate 645 to have a flexible height adjustment effect.

[0054] Reference Figures 10-11The second locking assembly 65 includes a swing arm 651, which is rotatably mounted inside the first connecting plate 641. The upper end of the swing arm 651 is provided with an inner tube 652, and a connecting shaft 653 is movably inserted into the inner tube 652. A second spring 654 for elastic pull-down is installed at the insertion end of the connecting shaft 653. A lever 655 is connected to the top of the connecting shaft 653. The lever 655 extends outward from the limiting slot 656, which is located on the outer side of one end of the first connecting plate 641. A mating strip 657 is rotatably connected to the bottom of the swing arm 651. A locking shaft 658 is rotatably connected to the end of the mating strip 657 away from the swing arm 651. The locking shaft 658 is inserted and locked to the outside of the moving plate 627.

[0055] Furthermore, after the rotating arm 625 is rotated into position, the lever 655 is moved to slide along the limiting slot 656. The lever 655 drives the swing arm 651 to rotate around the inside of the first connecting plate 641 through the connecting shaft 653. When the swing arm 651 rotates, it pushes the locking shaft 658 forward through the connecting bar 657, so that the locking shaft 658 is inserted into the corresponding locking hole of the moving plate 627, locking the rotating arm 625 and the moving plate 627 relative to each other. The second spring 654 applies a downward elastic force to the connecting shaft 653, so that the lever 655 remains locked at the end of the limiting slot 656 when there is no external force, preventing the lever 655 from accidentally dislodging due to ship vibration, and ensuring reliable locking between the rotating arm 625 and the moving plate 627 under the right-angle tube clamping state.

[0056] The limiting slot 656 is opened in a semi-circular groove shape, and the limiting end of the limiting slot 656 is bent and extended.

[0057] Furthermore, the semi-circular groove provides a smooth sliding path for the lever 655, making it easy for the operator to slide the lever 655 along the arc with one hand; the limiting end is bent and extended to form a locking notch, which naturally locks when the lever 655 slides into the bent extension section. Combined with the elastic pull of the second spring 654, the lever 655 will not automatically disengage from the locking position when there is no external force, ensuring the locking reliability of the second locking assembly 65 under ship vibration conditions.

[0058] The lever 655 is movably embedded in the locking mechanism of the swing arm 651, and the lever 655 extends to the outer end of the limiting slot 656 to support manual operation.

[0059] Furthermore, the extended end of the lever 655 extends to the outside of the limiting slot 656, allowing the operator to manually move the lever 655 to perform locking and unlocking operations without the need for tools. At the same time, the extended end provides a clear visual indication of the locked position, making it easy for the operator to visually confirm whether the second locking component 65 is currently in the locked or unlocked state.

[0060] The working principle of this application is as follows: First, in the initial straight pipe clamping state, the first clamp 4 is fixed to the front side of the upper end of the steel base 1, and the second clamp 5 is supported on the rear side of the upper end of the steel base 1 through the pipe adaptation device 6. The two maintain the same horizontal height and form a straight pipe clamping distance. The first clamp 4 and the second clamp 5 are both equipped with an elastic buffer layer of polytetrafluoroethylene, and the surface of the elastic buffer layer is provided with anti-slip texture, which can effectively avoid direct rigid contact between the clamp and the fiberglass pipe wall, prevent the pipe wall from being scratched and stress concentration cracking. The first clamp 4 and the second clamp 5 cooperate to clamp the straight pipe section of fiberglass pipe in a horizontal posture. Subsequently, when it is necessary to switch the bracket to the right-angle tube clamping state, the operator rotates the screw 61, driving the base plate 621 to slide backward along the inside of the steel base 1. The base plate 621 drives the two side plates 622 to move backward synchronously. During the sliding process of the side plates 622, the reverse Z-shaped transmission groove 623 opened inside them guides the roller 624. The roller 624 first slides along the top horizontal section of the transmission groove 623, then descends along the inclined transition section, and finally takes position along the bottom horizontal section, thereby driving the rotating arm 625 to rotate counterclockwise around the axis. The needle rotates precisely 90°, and the rotating arm 625 drives the first connecting plate 641 and the entire telescopic assembly 64 to rotate synchronously through the shaft, so that the second clamp 5 installed outside the second connecting plate 644 rotates from the horizontal straight pipe clamping posture to the vertical right-angle pipe clamping posture. When the roller 624 is in the top horizontal section, the rotating arm 625 is in the straight pipe clamping position. During the process of the roller 624 descending through the inclined transition section, the rotating arm 625 gradually rotates counterclockwise. When the roller 624 is in the bottom horizontal section, the rotating arm 625 is in the right-angle pipe clamping position. Next, during the counterclockwise rotation of the rotating arm 625, the first limiting shaft 628 fixed on one side of the rotating arm 625 and the second limiting shaft 629 fixed outside the locking plate 626 gradually approach each other and abut against each other when the rotating arm 625 rotates to the 90° limit position. Through the limiting cooperation of the two, the rotation angle is precisely and stably controlled at 90° to prevent over-rotation. At the same time, the rotating arm 625, which has been rotated into position, is driven by the synchronous backward movement of the locking plate 626 and the moving plate 627, which increases the distance between the second clamp 5 and the first clamp 4 after rotation, preventing them from being overly clustered due to the rotation action. This provides sufficient clamping space for the right-angle bend section of the fiberglass pipe and effectively improves the clamping adaptability of the right-angle pipe. Based on this, after the movable plate 627 moves to the designated position along with the side plate 622, the insertion shaft 631 and the connecting block 632 slide synchronously along the docking groove 633 to the position of the locking groove 637 on one side. At this time, the first spring 635 pushes the movable frame 634 downward, so that the ball 636 is embedded in the locking groove 637, realizing the automatic locking of the connecting block 632 and the steel base 1, thereby fixing the movable folding assembly 62 as a whole relative to the steel base 1, effectively avoiding accidental slippage in the working state, and ensuring the stability of the structure in the right-angle tube clamping state; Meanwhile, when the vertical height of the second clamp 5 needs to be adjusted to adapt to different installation positions, the operator pulls the second connecting plate 644 upward. The second connecting plate 644 drives the vertical tube 643 to extend upward along the positioning tube 642, and simultaneously drives the telescopic plate 645 to slide upward along the guide plate 6410. At this time, the locking shaft 649 at the bottom of the clamp 646 moves out from the inside of the first switching groove 6412 and slides upward along the right side of the guide groove 6411. When it slides to the required height, the elastic strip 647 pushes the clamp 646, so that the locking shaft 649 automatically embeds into the telescopic locking groove 6413 of the corresponding height, realizing the elastic locking and locking of the telescopic plate 645 and the guide plate 6410, and completing the rapid positioning and fixing of the second clamp 5 at any adjustable height. Furthermore, when the second clamp 5 needs to be lowered and reset, the operator continues to pull the second connecting plate 644 upward, causing the clamp 646 to drive the clamp shaft 649 to move upward along the guide groove 6411 into the second switching groove 6414. At this time, the unlocking groove 648 opened on the outside of the clamp 646 will lock with the right-angle bent end of the elastic strip 647 at the bottom, so that the clamp 646 is in a locked and stationary state. Thus, the clamp shaft 649 cannot elastically engage with the telescopic clamp groove 6413. Then, the operator pushes the second connecting plate 644 downward, and the clamp 646 drives the clamp shaft 649 to descend along the second switching groove 6414 and enter the guide groove 6411. It continues to move downward until it re-enters the first switching groove 6412. Since the entry end of the first switching groove 6412 is set with an inclined surface, the clamp 646 automatically releases the lock between the elastic strip 647 and the unlocking groove 648 during the movement of the clamp 646. The clamp 646 returns to its elastic and active state, providing convenient preparation for subsequent telescopic locking. Finally, after the telescopic assembly 64 has flipped, the operator moves the lever 655 to slide along the limiting slot 656. The lever 655 drives the swing arm 651 to rotate around the inside of the first connecting plate 641 through the connecting shaft 653. When the swing arm 651 rotates, it pushes the locking shaft 658 forward through the connecting bar 657, so that the locking shaft 658 is inserted into the corresponding locking hole of the moving plate 627, locking the swing arm 625 relative to the moving plate 627, further strengthening the support stability of the telescopic assembly 64 after flipping, and ensuring the overall structure is rigid and reliable in the right-angle tube clamping state; the second spring 654 applies a downward elastic force to the connecting shaft 653, so that the lever 655 is kept in the locked position at the end of the limiting slot 656 when there is no external force, preventing the lever 655 from accidentally dislodging due to ship vibration; In summary, the system allows for flexible switching between straight pipe clamping and right-angle pipe clamping modes for marine fiberglass pipe supports. It also features adjustable height of the second clamp 5, precise limit of the flip angle, and multi-point locking to prevent loosening, effectively solving the problem of poor adaptability of existing supports to different pipe types.

[0061] This application provides a marine fiberglass pipe support. Through the reverse Z-shaped transmission groove 623 of the movable folding component 62 in the pipe adaptation device 6 and the guide cooperation of the roller 624, the rotating arm 625 is driven to rotate 90° counterclockwise, so that the second clamp 5 can flexibly switch between the straight pipe clamping posture and the right-angle pipe clamping posture. Combined with the coordinated locking of the first locking component 63, the telescopic component 64 and the second locking component 65, the problem of poor adaptability of existing supports to different pipe types is effectively solved. At the same time, the first clamp 4 and the second clamp 5 are provided with an elastic buffer layer of polytetrafluoroethylene, which can effectively avoid direct rigid contact between the clamp and the fiberglass pipe wall, prevent the pipe wall from being scratched and stress concentration cracking, and is especially suitable for the support and fixation of fiberglass pipes in narrow cabins such as ships and marine observation platforms.
