Description

Technical Field

[0001] This utility model relates to the field of isolation technology, and more specifically, to an isolation device for chemical safety. Background Technology

[0002] First, existing isolation equipment generally lacks an effective modular management system. Most isolation equipment adopts an integral structure or a simple splicing design, lacking modular units and connection interfaces. This design results in large equipment size, difficult transportation, and difficulty in flexibly configuring according to the actual needs of different chemical scenarios. In complex chemical environments, different areas have different requirements for isolation and protection, and existing technologies cannot provide targeted modular combination solutions, which greatly limits the applicability and protective effect of the equipment.

[0003] The connection methods between modules are outdated and unreliable. Traditional isolation equipment mainly relies on bolts, welding, or simple clips to connect components. Bolted connections require specialized tools, are cumbersome to operate, and are prone to loosening over time. While welded connections are strong, they are completely non-removable, hindering equipment maintenance and upgrades. Furthermore, the modular assembly and disassembly process of existing isolation equipment is complex and time-consuming. In chemical production processes, equipment maintenance, internal inspections, or emergency handling often require rapid disassembly of isolation components. However, current technologies often require multiple people working together and using various tools to complete the disassembly and assembly, resulting in low efficiency. Especially in emergency situations, inconvenient disassembly and assembly can lead to rescue delays and increase the risk of accidents. Utility Model Content

Some corner plates are installed around the top cover, and some corner plates are installed at the bottom of the side plates. The door body is rotatably installed on one end face of the side plate. The snapping pipes are fixedly installed on the corner plates. The snapping rods pass through the side plates and corner plates and cooperate with the snapping pipes to fix the three sets of side plates to the bottom of the top cover. The fixing and snapping mechanism includes a guide frame, a guide groove, a centripetal frame, a centripetal groove, and an embedding block. The guide frame is rotatably limited and installed inside the side wall of the snapping pipe. The guide groove is located inside the guide frame. The centripetal frame is fixedly installed on the outer wall of the snapping pipe. The centripetal groove is located on the centripetal frame. The top and bottom ends of the embedding block are slidably configured to cooperate with the guide groove and the centripetal groove. The guide frame pushes the embedding block to slide centripetally on the centripetal frame, so that the embedding block is embedded in or away from the snapping rod.

[0008] The present invention is further configured such that the snap-fit ​​auxiliary mechanism includes a rotating block, a winding rod, a return spring sleeve, an outer rotating sleeve, and a linkage block. The winding rod is fixedly installed on the outer wall of the snap-fit ​​tube, the return spring sleeve is fitted on the winding rod, multiple sets of rotating blocks rotate on the winding rod, one end of the rotating block is connected to the return spring sleeve, and the bottom end of the rotating block is connected to the guide frame. The outer rotating sleeve is threadedly connected to the outer wall of the snap-fit ​​tube, and the linkage block is installed on the outer wall of the outer rotating sleeve.

[0009] The present invention is further configured such that multiple sets of corner plates are provided, and a foot plate is installed on the corner plate at the bottom end of the side plate. The foot plate enhances the stability of the device, prevents tilting or sliding, and improves safety.

[0010] The present invention is further configured such that a pin sleeve and a guide plate are installed on the front end face of the door body, and the pin sleeve and the guide plate are respectively installed on the two door bodies. When the door body is closed, the pin sleeve forms a locking channel, which facilitates the insertion of the pin to achieve locking.

[0011] The present invention is further configured such that the guide plate is slidably mounted with a pin, and a rotating bolt is rotatably mounted on one end face of the guide plate. The pin passes through the guide plate and extends into the pin sleeve to achieve reliable locking of the door and prevent accidental opening.

[0012] The present invention is further configured such that the rotating bolt is threadedly connected to the pin, one end of the pin extends into the pin sleeve to fix the two door bodies, and the rotating bolt is threadedly connected to the pin, thereby increasing the locking force by rotation and preventing the pin from loosening.

[0013] The present invention is further configured such that a connecting plate is installed at the bottom end of the side wall of the clamping tube, and the connecting plate is fixedly installed on one end face of the corner plate, thereby fixing the clamping tube and the corner plate and enhancing the strength of the connection point.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an isolation device for chemical safety, which has the following beneficial effects:

[0017] This utility model features a modular connection mechanism, enabling standardized assembly and rapid connection of the isolation equipment. Through the combined design of corner plates, snap-fit ​​pipes, and snap-fit ​​rods, the top cover and side plates can be quickly and accurately positioned and firmly connected without the need for complex tools.

This modular design significantly improves the assembly efficiency and adaptability of the equipment, meeting the isolation requirements of different chemical environments, while also facilitating transportation, storage, and maintenance.

[0018] This utility model is equipped with a fixed locking mechanism. Through the synergistic action of the guide frame, guide groove, centripetal frame and centripetal groove, the embedded block is precisely centripetally locked to the locking rod. This double locking design significantly improves the connection strength and stability, and can effectively resist vibration and impact in chemical environments. At the same time, the sliding design of the guide block and the groove ensures the motion accuracy, reduces operational failures, and improves the reliability of the equipment in harsh environments.

[0019] This utility model is equipped with a snap-fit ​​auxiliary mechanism. The combination design of the rotating block, the winding rod and the return spring sleeve makes the transmission of operating torque more efficient and reduces the difficulty of operation.

[0029] Please see Figures 1-5A chemical safety isolation device includes a modular connection mechanism, a fixing and snapping mechanism, and a snapping auxiliary mechanism. The modular connection mechanism includes side plates 1, a top cover 2, a door 3, corner plates 4, snapping pipes 5, and snapping rods 6. Some corner plates 4 are installed around the top cover 2, and some corner plates 4 are installed at the bottom of the side plates 1. The door 3 is rotatably installed on one end face of the side plates 1. The snapping pipes 5 are fixedly installed on the corner plates 4. The snapping rods 6 pass through the side plates 1 and the corner plates 4, and cooperate with the snapping pipes 5 to snap and fix the three sets of side plates 1 to the bottom of the top cover 2. At the end, the fixed locking mechanism includes a guide frame 7, a guide groove 8, a centripetal frame 9, a centripetal groove 10, and an embedded block 11. The guide frame 7 is rotatably limited and installed inside the side wall of the locking tube 5. The guide groove 8 is located inside the guide frame 7. The centripetal frame 9 is fixedly installed on the outer wall of the locking tube 5. The centripetal groove 10 is located on the centripetal frame 9. The top and bottom ends of the embedded block 11 are slidably configured to cooperate with the guide groove 8 and the centripetal groove 10. The guide frame 7 pushes the embedded block 11 to slide centripetally on the centripetal frame 9, so that the embedded block 11 is embedded in or away from the locking rod 6.

[0030] In this embodiment, the module connection mechanism connects the top cover 2 and the side plate 1 through the corner plate 4 to form a closed space. During operation, the three sets of side plates 1 are aligned with the top cover 2, the locking tube 5 on the corner plate 4 corresponds to the hole on the side plate 1, the locking rod 6 passes through the side plate 1 and the corner plate 4, and extends into the locking tube 5 to achieve initial fixation. The door 3 is installed on one set of side plates 1 and is closed by the pin sleeve 18 and the guide plate 19. After the pin 20 extends into the pin sleeve 18, it is locked by the rotating bolt 21 to form a complete isolation space. The foot plate on the bottom corner plate 4 of the side plate 1 17 provides stable support and the fixed locking mechanism enhances the robustness of the module connection. During operation, rotating the guide frame 7 and the guide groove 8 drives the top guide block 23 of the embedded block 11 to move. At the same time, the bottom guide block 23 of the embedded block 11 slides in the centripetal groove 10 of the centripetal frame 9, generating centripetal motion. This compound motion enables the embedded block 11 to move precisely towards the center and embed into the locking rod 6, forming a second locking to prevent the locking rod 6 from loosening or falling off. When disassembly is required, rotating the guide frame 7 in the opposite direction moves the embedded block 11 away from the locking rod 6, releasing the lock.

[0031] The locking auxiliary mechanism includes a rotating block 12, a winding rod 13, a return spring sleeve 14, an outer rotating sleeve 15, and a linkage block 16. The winding rod 13 is fixedly installed on the outer wall of the locking tube 5. The return spring sleeve 14 is fitted onto the winding rod 13.

The bottom end of the rotating block 12 is connected to the guide frame 7. The outer rotating sleeve 15 is threadedly connected to the outer wall of the locking tube 5. The linkage block 16 is installed on the outer wall of the outer rotating sleeve 15. The linkage block 16 can be embedded in the rotating block 12, so that the rotating block 12 rotates on the winding rod 13, so that the guide frame 7 rotates stably and is easy to reset.

[0032] In this embodiment, the outer rotating sleeve 15 rotates to drive the linkage block 16 to move. The linkage block 16 is embedded in the rotating block 12, pushing the rotating block 12 to rotate on the winding rod 13. The bottom of the rotating block 12 is connected to the guide frame 7, transmitting rotational force to make the guide frame 7 rotate stably. After locking is completed, the reset spring sleeve 14 provides a reset force to the system. After the linkage block 16 releases the rotating block 12, the rotating block 12 returns to its initial position, preparing for the next operation. This design enhances the convenience of operation and the reliability of the locking system.

Pin sleeves 18 and guide plates 19 are installed on the front end face of the door body 3, and pin sleeves 18 and guide plates 19 are respectively set on two door bodies 3. A pin 20 is slidably installed on the guide plate 19, and a rotating bolt 21 is rotatably installed on one end face of the guide plate 19. The rotating bolt 21 is threadedly connected to the pin 20. One end of the pin 20 extends into the pin sleeve 18 to fix the two door bodies 3. A connecting plate 22 is installed at the bottom end of the side wall of the snap-fit ​​pipe 5, and the connecting plate 22 is fixedly installed on one end face of the corner plate 4. Guide blocks 23 are installed at the top and bottom ends of the embedded block 11, and the guide blocks 23 are slidably guided in cooperation with the guide groove 8 and the centripetal groove 10.

[0034] More specifically, the three sets of side plates 1 and top cover 2 are combined, the corner plates 4 and locking tubes 5 are aligned, the locking rods 6 are inserted through the side plates 1 and corner plates 4 and into the locking tubes 5 to achieve a preliminary connection, the guide frame 7 is rotated to drive the embedded block 11 to move towards the center and embed into the locking rod 6 to form a firm lock, the rotating block 12 is operated through the outer rotating sleeve 15 and the linkage block 16 to optimize the rotation process of the guide frame 7 and ensure the locking is stable, the door 3 is closed so that the two door bodies 3 are connected, the guide plate 19 and the pin sleeve 18 are aligned, the pin 20 is inserted through the guide plate 19 and into the pin sleeve 18, the rotating bolt 21 is rotated to lock the pin 20, the foot plate 17 provides stable support, forming a complete and closed chemical safety isolation space.

[0035] In summary, when the overall equipment is in use or running: when the module connection mechanism is required to run, the module connection mechanism connects the top cover 2 and the side plate 1 through the corner plate 4 to form a closed space. During operation, the three sets of side plates 1 are aligned with the top cover 2, the locking tube 5 on the corner plate 4 corresponds to the hole on the side plate 1, the locking rod 6 passes through the side plate 1 and the corner plate 4 and extends into the locking tube 5 to achieve initial fixation, the door 3 is installed on a set of side plates 1, and is closed by the pin sleeve 18 and the guide plate 19. After the pin 20 extends into the pin sleeve 18, it is locked by the rotating bolt 21 to form a complete isolation space. The foot plate 17 on the bottom corner plate 4 of the side plate 1 provides stable support.

[0036] When the locking mechanism is in operation, it enhances the robustness of the module connection. During operation, rotating the guide frame 7 and the guide groove 8 moves the top guide block 23 of the embedded block 11. At the same time, the bottom guide block 23 of the embedded block 11 slides in the centripetal groove 10 of the centripetal frame 9, generating centripetal motion. This combined motion causes the embedded block 11 to move precisely towards the center and embed into the locking rod 6, forming a second locking to prevent the locking rod 6 from loosening or falling off. When disassembly is required, rotating the guide frame 7 in the opposite direction moves the embedded block 11 away from the locking rod 6, releasing the lock.

[0037] When the auxiliary locking mechanism is in operation, the outer rotating sleeve 15 rotates, causing the linkage block 16 to move. The linkage block 16 embeds into the rotating block 12, pushing the rotating block 12 to rotate on the winding rod 13. The bottom of the rotating block 12 is connected to the guide frame 7, transmitting rotational force to make the guide frame 7 rotate stably. After locking is completed, the reset spring sleeve 14 provides a reset force to the system. After the linkage block 16 releases the rotating block 12, the rotating block 12 returns to its initial position, preparing for the next operation. This design enhances the convenience of operation and the reliability of the locking system.

[0038] Combine the three sets of side plates 1 with the top cover 2, align the corner plates 4 and the locking tube 5, insert the locking rod 6 through the side plates 1 and the corner plates 4, and extend into the locking tube 5 to achieve a preliminary connection. Rotate the guide frame 7 to drive the embedded block 11 to move towards the center and embed into the locking rod 6 to form a firm lock. Operate the rotating block 12 through the outer rotating sleeve 15 and the linkage block 16 to optimize the rotation process of the guide frame 7 and ensure stable locking.
