[0044] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solutions of the present invention, but are not intended to limit the scope of protection of the present invention.

[0045] Example:

[0046] like Figures 1 to 10 As shown, the present invention provides an oxygen pipeline purification device that prevents unauthorized disassembly, including a purification device 11 and a disassembly-resistant housing. Connecting pipes 31 are provided on both sides of the disassembly-resistant housing. First flanges 12 are provided at both ends of the purification device 11. Second flanges 32 are provided at one end of each of the two sets of connecting pipes 31. An anti-disassembly ring is provided between the first flange 12 and the second flange 32. The ends of the anti-disassembly ring are respectively clamped on the first flange 12 and the second flange 32. By clamping the ends of the anti-disassembly ring on the first flange 12 and the second flange 32, the unauthorized disassembly of the purification device 11 and the connecting pipes 31 by non-professionals can be prevented, thereby improving the safety and stability of the device and avoiding safety hazards such as oxygen leakage caused by unauthorized disassembly.

[0047] The main pipeline assembly and purification device 11 are located within a tamper-resistant housing, which is equipped with an alarm assembly and control module 93. By placing the alarm assembly and control module 93 within the tamper-resistant housing, a timely alarm is issued if the purification device 11 is illegally disassembled, enhancing the device's early warning capabilities for abnormal situations and ensuring the safe operation of the entire oxygen delivery system. The control module 93 can utilize an RX63N microcontroller.

[0048] The alarm assembly includes an emitter 91 and a sensor 92, and a control module 93 is electrically connected to the emitter 91 and the sensor 92. When the anti-tamper housing is opened or the internal structure is abnormally touched, the signal transmission state between the emitter 91 and the sensor 92 changes. The control module 93 receives this change signal and triggers the corresponding alarm measures. Through this arrangement, abnormal conditions of the purification device 11 can be detected immediately, improving the safety and reliability of the device. The sensor 92 can adopt the E3Z-D61 model fiber optic sensor, and the emitter 91 can adopt the FA-N11C model infrared transmitter.

[0049] like Figure 2 、 3 As shown in Figures 4 and 5, the tamper-evident ring includes a main plate 51, with multiple sets of latches 52 disposed on one side of the main plate 51. These sets of latches 52 are evenly distributed along the circumference of the main plate 51. These multiple sets of evenly distributed latches 52 cooperate with the latches 13 on the first flange 12 to provide a secure connection. This arrangement ensures a secure connection between the tamper-evident ring and the first flange 12, making it difficult to pry or disassemble, thereby enhancing the tamper-evident performance of the device.

[0050] A first spring 53 is provided on the other side of the main plate 51. A retaining ring 54 is provided at one end of the first spring 53. The retaining ring 54 is provided with multiple sets of stoppers 56, which are arranged circumferentially on the main plate 51. The elastic action of the first spring 53 enables the stoppers 56 to snap into the first stop slots 34 of the second flange 32. This arrangement ensures the connection between the anti-tamper ring and the second flange 32, improving the stability of the device under complex operating conditions.

[0051] Seal rings 57 are provided on both sides of the mainboard 51. The seal rings 57 can fill the small gap between the anti-tamper ring and the flange. This arrangement can enhance the sealing of the connection of the purification device 11, prevent oxygen leakage, and improve the gas delivery efficiency and safety of the device.

[0052] The first flange 12 is provided with multiple sets of retaining blocks 13, within which retaining blocks 52 are secured. These retaining blocks 52 are made of rubber. The rubber retaining blocks 52 have a certain degree of elasticity, which facilitates installation and removal of the anti-tamper ring from the first flange 12 while ensuring connection reliability and enhancing the device's usability and stability.

[0053] The second flange 32 is provided with a retaining seat 33, which defines a plurality of first retaining grooves 34. Retaining blocks 56 are positioned within these first retaining grooves 34. This retaining structure, in conjunction with the retaining block 52 and retaining seat 13 on the other side of the anti-tampering ring, secures the anti-tampering ring from both sides. This arrangement further ensures the secure installation of the anti-tampering ring, preventing it from loosening or shifting during pipeline operation and improving the overall stability of the device.

[0054] Both the first flange 12 and the second flange 32 are detachably connected to the anti-tamper ring via bolts. This bolted connection ensures strength while also facilitating disassembly using specialized tools when necessary. This arrangement allows for convenient removal of the anti-tamper ring when maintaining or replacing components of the purification device 11, improving the device's maintainability.

[0055] A slip ring 58 is mounted on the mainboard 51 and slidably connected to the mainboard 51. Two sets of through holes 59 are provided in the slip ring 58. A sliding groove 511 is provided on the sidewall of the mainboard 51. Two sets of unlocking grooves 55 are located on the end of the sliding groove 511 away from the slip ring 58. The combination of the slip ring 58, the sliding groove 511, and the unlocking grooves 55 forms a unique unlocking mechanism that can only be unlocked using a specific disassembly device. This arrangement further enhances the anti-tampering ring's resistance to unauthorized disassembly, improving the device's safety.

[0056] Both the first flange 12 and the second flange 32 are provided with positioning blocks 61. The positioning blocks 61 provide a positioning reference for the anti-tamper ring and the disassembly device during installation. This arrangement allows for faster and more accurate installation and disassembly operations, improving the efficiency of the device.

[0057] like Figure 5 、 6 As shown in FIG. 7 , a disassembly device is also included, which includes a fixing plate 62. Fixing plate 62 serves as the base structure of the disassembly device, providing a mounting and support platform for other components. This arrangement allows the anti-tampering ring to be removed using the disassembly device, improving the operability of the device during maintenance.

[0058] Two sets of guide rods 63 and a bidirectional screw 64 are mounted on the fixed plate 62. Two sets of movable plates 65 are mounted on the bidirectional screw 64. The two sets of guide rods 63 are sleeved onto the fixed plate 62. Rotating the bidirectional screw 64 causes the two sets of movable plates 65 to move toward or away from each other along the guide rods 63, thereby adjusting the relative position of the disassembly device and the purification device 11. This arrangement allows for flexible adjustment of the disassembly device to accommodate purification devices 11 of varying specifications, enhancing its versatility.

[0059] One end of the bidirectional screw rod 64 is provided with a rotating disk 66. The rotating disk 66 provides a convenient force application point for the rotation of the bidirectional screw rod 64. By such an arrangement, the bidirectional screw rod 64 can be rotated more easily to operate the disassembly device, thereby improving the convenience of the device disassembly process.

[0060] Two sets of guide rings 67 are mounted on either side of the fixing plate 62. Sliders 68 are slidably mounted on the guide rings 67, and an unlocking lever is mounted on the sliders 68. Guided by the guide rings 67 and sliders 68, the unlocking lever can be precisely aligned with the unlocking point on the tamper-evident ring. This arrangement allows precise operation of the unlocking lever to unlock the tamper-evident ring.

[0061] The movable plate 65 is provided with multiple sets of first positioning grooves 81, into which the positioning blocks 61 are positioned. The cooperation between the positioning blocks 61 and the first positioning grooves 81 allows the disassembly device to be quickly positioned and secured when installed on the purification device 11, preventing it from shifting during disassembly. This arrangement ensures a secure installation of the disassembly device and enhances its stability during disassembly.

[0062] like Figure 8 、 9As shown in Figures 10 and 11 , the unlocking lever includes a main lever 71, a secondary lever 72 extending therethrough, a pull rod 76 extending therethrough, and a positioning post 73 at one end. A second positioning slot 82 is defined within the inner wall of the slide slot 511 of the main plate 51. One end of the positioning post 73 is secured within the second positioning slot 82, and a second spring 74 is sleeved around the positioning post 73. The second spring 74 retains the positioning post 73 within the second positioning slot 82, providing both positioning and locking. When unlocking is desired, pulling the pull rod 76 disengages the positioning post 73 from the second positioning slot 82. This arrangement allows the unlocking lever to be positioned and unlocked by controlling the pull rod 76, improving the controllability of the unlocking operation of the device.

[0063] Two sets of unlocking rings 77 are sleeved on the auxiliary lever 72. Two sets of first and second pressure levers 78 and 79 are located between the two sets of unlocking rings 77. One end of the first pressure lever 78 is hinged to one end of the second pressure lever 79, and the other end is hinged to each of the two sets of unlocking rings 77. This linkage structure allows the first and second pressure levers 78 and 79 to interlock when the auxiliary lever 72 is rotated, thereby engaging or disengaging the unlocking slot 55 on the main board 51. This arrangement allows the anti-tamper ring to be unlocked with a simple rotation, improving the convenience of the unlocking operation of the device.

[0064] Each of the auxiliary levers 72 is provided with a second retaining groove 83, through which the first and second pressure rods 78, 79 pass to engage within the unlocking groove 55. The second retaining groove 83 serves to limit and guide the first and second pressure rods 78, 79, ensuring they are accurately engaged within the unlocking groove 55. This arrangement ensures the reliability of the unlocking mechanism and enhances the accuracy and stability of the unlocking operation of the device.

[0065] Main lever 71 is equipped with a pivot post 75, which is mounted on auxiliary lever 72. This pivot post 75 allows main lever 71 to rotate relative to auxiliary lever 72, facilitating the user's operation of the release lever at various angles. This arrangement allows the release lever's operating angle to be adjusted based on the actual operating space, enhancing the device's adaptability to various installation environments.

[0066] The tamper-evident housing consists of a main housing 21 and a cover 22. A transmitter 91 is mounted on the cover 22, and a sensor 92 is mounted on the main housing 21. Transmitter 91 transmits signals toward sensor 92. When the cover 22 is opened, the signal between transmitter 91 and sensor 92 is interrupted, triggering an alarm. This arrangement allows for prompt detection of any abnormal opening of the tamper-evident housing, enhancing the overall safety of the device.

[0067] An electromagnetic lock 41 is installed on the main housing 21, and an attraction plate 42 is installed on the cover 22. The electromagnetic lock 41 is magnetically connected to the attraction plate 42 and electrically connected to the control module 93. When an abnormal disassembly signal is detected, the control module 93 energizes the electromagnetic lock 41, increasing the locking force on the cover 22. This arrangement further prevents unauthorized disassembly and enhances the device's anti-disassembly performance. The electromagnetic lock 41 can be a DS-1200 model.

[0068] A photoelectric alarm 43 is installed on the tamper-evident housing and is electrically connected to the control module 93. Once the control module 93 detects an abnormality, the photoelectric alarm 43 emits an audible and visual alarm. This arrangement allows for immediate and intuitive detection of any abnormalities in the purification device 11, enhancing the effectiveness of warnings. The photoelectric alarm 43 can be model ABL60-106N.

[0069] The specific usage and function of this embodiment are as follows:

[0070] Align the first flanges 12 at both ends of the purification device 11 with the second flange 32 at one end of the connecting pipe 31. At this time, the clamping blocks 52 at both ends of the anti-disassembly ring are aligned with the clamping seat 13 on the first flange 12, and the limiting block 56 is aligned with the first limiting groove 34 on the limiting seat 33 of the second flange 32. Insert the clamping block 52 into the clamping seat 13 and the limiting block 56 into the first limiting groove 34 to preliminarily fix the anti-disassembly ring. This ensures clear positioning during the installation process and facilitates user operation. At the same time, through the cooperation of the clamping block 52 with the clamping seat 13, and the limiting block 56 with the first limiting groove 34, the preliminary positioning connection between the purification device 11 and the pipeline can be quickly achieved, thereby improving installation efficiency and providing a stable foundation for subsequent bolt tightening to ensure the initial stability of the connection.

[0071] Bolts are used to further secure the first and second flanges 12, 32, and the tamper-evident rings. This ensures that the connection between the purification device 11 and the pipeline will not loosen due to pressure or other factors during oxygen delivery, enhancing the stability of the overall structure of the device. During installation, the sealing rings 57 on either side of the mainboard 51 are squeezed between the tamper-evident ring and the flanges, filling the small gap. This prevents oxygen leakage from the connection, improves the sealing performance of the device, ensures the safety of oxygen delivery, and prevents safety accidents caused by oxygen leaks.

[0072] Once installed, the anti-tamper ring is connected between the first flange 12 and the second flange 32. The engagement of the retaining block 52, the stopper 56, and the tightening of the bolts make unauthorized disassembly difficult for non-professionals. Any attempt at forced disassembly would disrupt the proper functioning of the slip ring 58, the unlocking slot 55, and other structures, triggering the alarm assembly. This protects the purification device 11 from arbitrary disassembly, ensuring the safety and stability of the oxygen delivery system and preventing serious consequences such as equipment damage or oxygen leaks caused by unauthorized disassembly.

[0073] The alarm assembly's transmitter 91 and sensor 92 continuously transmit signals. When the tamper-evident housing is opened or the tamper-evident ring is abnormally activated, the signal transmission status between transmitter 91 and sensor 92 changes, and the control module 93 receives this change signal. This monitoring mechanism monitors the safety status of the purification device 11 and promptly notifies the user of any abnormalities, improving the device's ability to warn against unauthorized operation and providing timely feedback to ensure system safety.

[0074] Bring the fixed plate 62 of the disassembly device close to the purification device 11, aligning the first positioning groove 81 on the movable plate 65 with the positioning blocks 61 on the first flange 12 and the second flange 32. After engaging the positioning blocks 61, the disassembly device is positioned on the purification device 11. This step facilitates the user to quickly install the disassembly device, ensures the accuracy and stability of the disassembly operation, and prevents the disassembly device from shifting during the disassembly process and damaging the equipment.

[0075] By rotating the turntable 66 at one end of the bidirectional screw 64, the bidirectional screw 64 drives the two sets of movable plates 65 to move along the guide rod 63, adjusting the movable plates 65 to the appropriate position so that the unlocking rod aligns with the through hole 59 of the slip ring 58 on the anti-tamper ring main plate 51. The turntable 66 facilitates the user to apply force to rotate the bidirectional screw 64, and the guide rod 63 provides a linear motion guide for the movable plates 65, allowing the position of the disassembly device to be flexibly adjusted to meet the disassembly requirements of purification devices 11 of different specifications, thereby improving the versatility and ease of operation of the disassembly device.

[0076] By pushing the unlocking lever, the pull rod 76 drives the positioning column 73 out of the second positioning slot 82 on the inner wall of the slide 511 of the main board 51. Simultaneously, the main rod 71 is rotated, driving the auxiliary rod 72 to rotate via the rotating column 75. As the auxiliary rod 72 rotates, the unlocking ring 77 mounted thereon drives the first and second pressure rods 78 and 79 to move. These rods pass through the second limiting slot 83 on the auxiliary rod 72 and disengage from the unlocking slot 55 of the main board 51. The coordinated structure of the positioning column 73 with the second positioning slot 82, and the first and second pressure rods 78 and 79 with the unlocking slot 55, makes the unlocking operation complex and professional, preventing unauthorized unlocking by non-professionals and enhancing the device's anti-unauthorized disassembly performance. At the same time, it ensures that professionals can successfully unlock the device through a specific operating procedure, meeting normal maintenance requirements.

[0077] After unlocking is completed, the bolts connecting the first flange 12, the second flange 32 and the anti-tampering ring can be removed, and then the anti-tampering ring can be removed to separate the purification device 11 from the pipeline.

[0078] When the cover 22 of the anti-dismantling housing is opened or the anti-dismantling ring is abnormally disassembled, the signal transmission between the transmitter 91 and the sensor 92 of the alarm component is blocked. After the control module 93 receives the signal change, it immediately triggers the photoelectric alarm 43 to emit an audible and visual alarm. This allows the user to intuitively detect abnormal conditions in the purification device 11 at the first possible moment, take timely measures to avoid the escalation of the accident, and enhance the warning effect of abnormal conditions in the device. At the same time, the control module 93 controls the electromagnetic lock 41 on the main shell 21 to be energized, and the magnetic connection force between the electromagnetic lock 41 and the attraction plate 42 on the cover 22 is enhanced, further locking the cover 22 to prevent illegal personnel from continuing to disassemble the device. The linkage between the electromagnetic lock 41 and the control module 93 enhances the anti-dismantling performance of the device and ensures the safety of the oxygen delivery system under abnormal conditions.

[0079] The basic principles, main features and advantages of the present invention are shown and described above. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments.
