It has the advantages of greatly simplifying the disassembly and assembly steps of the instrument and support frame, making the disassembly and assembly operations simple and labor-saving, and enabling rapid assembly and separation of the instrument and support frame, thus adapting to frequent disassembly and assembly scenarios in front of the furnace.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a split-type copper liquid oxygen analyzer that can be externally connected to an industrial large screen, including a support frame, one side of which is fixedly connected to the outer wall of a copper melting furnace, the oxygen analyzer body is placed on the top of the support frame, and two connecting blocks are fixedly connected to both ends of the oxygen analyzer body. The top of the four connecting blocks is provided with a circular groove 1, and the top of the support frame is provided with four circular grooves 2. Correspondingly, the circular grooves 1 and 2 are provided with a fixing component. The fixing component includes a rod inserted into a circular groove one and a circular groove two. A return spring is fixedly connected to the lower inner wall of the rod. A driving block is fixedly connected to the top of the return spring. A pressing rod is fixedly connected to the top of the driving block. The top of the pressing rod passes through the rod and extends to the outside of the rod. The outer surface of the drive block is slidably connected with four snap-fit ​​blocks, and the inner surface of the circular groove two is provided with snap-fit ​​grooves for use with the four snap-fit ​​blocks. The four snap-fit ​​blocks pass through the insertion rod and extend into the corresponding snap-fit ​​grooves respectively.

[0007] Preferably, the driving block is frustum-shaped, and connecting plates are fixedly connected to both the upper and lower ends of the driving block. The lower connecting plate is fixedly connected to the reset spring, and the upper connecting plate is fixedly connected to the insertion rod.

[0008] Preferably, the outer surface of the drive block is provided with four anti-slip grooves, and one end of the snap-fit ​​block is fixedly connected to an anti-slip slider that works in conjunction with the anti-slip grooves. The anti-slip slider and the anti-slip grooves are convex in shape.

[0018] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0019] To better understand the purpose, structure, and function of this invention, the invention will be described in further detail below with reference to the accompanying drawings.

[0020] Example 1 like Figures 1 to 6As shown, the present invention provides a split-type copper liquid oxygen analyzer that can be connected to an external industrial large screen. It includes a support frame 1, one side of which is connected to the outer wall of the copper melting furnace. The oxygen analyzer body 2 is placed on the top of the support frame 1. The oxygen analyzer body 2 is a split structure and is connected to an external industrial large screen. The oxygen analyzer body 2 is equipped with a detection probe for inserting into the copper liquid to detect the oxygen content. Two connecting blocks 21 are fixedly connected to both ends of the oxygen analyzer body 2. The top of the four connecting blocks 21 is provided with a circular groove 22. The top of the support frame 1 is provided with four circular grooves 11. The corresponding circular grooves 22 and circular grooves 11 are provided with a fixing component 4. The fixing component 4 includes a rod 41 inserted into a circular groove 22 and a circular groove 11. A return spring 42 is fixedly connected to the lower inner wall of the rod 41. A drive block 43 is fixedly connected to the top of the return spring 42. A pressing rod 44 is fixedly connected to the top of the drive block 43. The top of the pressing rod 44 passes through the rod 41 and extends to the outside of the rod 41. Four locking blocks 432 are slidably connected to the outer surface of the drive block 43. The inner surface of the circular groove 11 is provided with locking grooves 12 that cooperate with the four locking blocks 432. The four locking blocks 432 pass through the insertion rod 41 and extend into the corresponding locking grooves 12. The support frame 1, the oxygen analyzer body 2 and the fixing component 4 cooperate with each other. The mechanical self-locking is completed by the insertion rod 41, the return spring 42, the drive block 43, the locking blocks 432 and the locking grooves 12. This simplifies the disassembly and assembly process of the oxygen analyzer body 2 and the support frame 1, eliminates the need for cumbersome locking operations, and solves the problem of inconvenient connection and disassembly between the instrument and the support frame 1.

[0021] The drive block 43 is shaped like a frustum. Both the upper and lower ends of the drive block 43 are fixedly connected to connecting plates 433. The lower connecting plate 433 is fixedly connected to the return spring 42, and the upper connecting plate 433 is fixedly connected to the insertion rod 41. The frustum-shaped drive block 43, together with the upper and lower connecting plates 433, connects the return spring 42 and the insertion rod 41 respectively. The vertical displacement of the drive block 43 is converted into the lateral extension and retraction of the locking block 432 by means of the inclined surface of the frustum. The transmission logic is simple and smooth, which improves the stability of the fixed component 4.

[0022] The outer surface of the drive block 43 is provided with four anti-detachment grooves 435. One end of the snap-fit ​​block 432 is fixedly connected to an anti-detachment slider 434 that is used in conjunction with the anti-detachment grooves 435. The anti-detachment slider 434 and the anti-detachment grooves 435 are convex. The convex anti-detachment grooves 435 and the anti-detachment slider 434 restrict the sliding trajectory of the snap-fit ​​block 432, prevent the snap-fit ​​block 432 from shifting, falling off, or jamming during long-term use, and extend the service life of the fixing component 4.

[0023] Two guide blocks 431 are fixedly connected to the outer surface of the lower connecting plate 433. The inner surface of the insert rod 41 is provided with a guide groove 46 that works with the two guide blocks 431. The guide blocks 431 and the guide groove 46 limit and guide the vertical movement of the drive block 43, preventing the drive block 43 from tilting when it rises and falls, ensuring that the four locking blocks 432 extend and retract synchronously, and improving the locking and alignment accuracy.

[0024] A tension spring 45 is wound around the outer surface of the insertion rod 41. The two ends of the tension spring 45 are fixedly connected to the connecting plate 433 located above and the upper inner wall of the insertion rod 41, respectively. The tension spring 45 is set on the outside of the insertion rod 41, forming a double reset structure with the reset spring 42. After pressing to unlock, it can drive the drive block 43 to rebound quickly, preventing the locking block 432 from failing to retract properly and causing locking failure, thus enhancing the reliability of the equipment.

[0025] The outer surface of the insertion rod 41 is engraved with an external thread 411. The insertion rod 41 is threaded with a pressure ring 412 through the external thread 411. The end of the pressure ring 412 near the connecting block 21 is provided with a flexible pad made of high temperature resistant material. The pressure ring 412 is assembled through the external thread 411 of the insertion rod 41, and the clamping distance can be adjusted. The high temperature resistant flexible pad at the end of the pressure ring 412 fits tightly against the connecting block 21, which is suitable for the high temperature environment in front of the furnace, eliminates assembly gaps, and improves the overall placement stability.

[0026] A limiting ring 413 is fixedly sleeved on the upper part of the outer surface of the insertion rod 41. The limiting ring 413 is fixedly sleeved on the upper part of the insertion rod 41 to limit the maximum tightening stroke of the pressure ring 412 and prevent the pressure ring 412 from coming off.

[0027] One end of the support frame 1 is fixedly connected to several mounting ear plates 3. The inner surface of each mounting ear plate 3 is threaded with a fastening bolt 31. The fastening bolt 31 passes through the mounting ear plate 3 and is locked and fixed to the side wall of the copper melting furnace. By using the mounting ear plate 3 on one side of the support frame 1 in conjunction with the fastening bolt 31, the support frame 1 can be detachably locked to the edge of the copper melting furnace. The base is flexible to disassemble and assemble, and can be adapted to various specifications of smelting furnace positions, making it more versatile.

[0028] Example 2 This embodiment is basically the same as the first embodiment in structure, except that the mounting ear plate 3 and fastening bolt 31 at the end of the support frame 1 are removed. Several hanging hooks are integrally formed on one side of the support frame 1. The hanging hooks are bent metal parts with the opening facing downwards. The inner side wall of the hooks is covered with a high temperature resistant anti-slip pad. During assembly, the hanging hooks of the support frame 1 are directly hooked onto the furnace edge of the copper melting furnace. The support frame 1 is positioned as a whole by relying on the bending structure of the hooks to clamp the furnace edge. There is no need for bolt locking operation. The operation of installing and removing the support frame 1 is faster. The support frame 1 can be quickly switched to different furnace opening positions, which is suitable for temporary testing and multi-station rotation testing scenarios.

[0029] The overall structure, assembly and locking method, and beneficial effects of the oxygen analyzer body 2, connecting block 21, and fixing component 4 in this embodiment are consistent with those in embodiment one.

[0030] Working principle and process: In use, first, the support frame 1 is locked and fixed to the edge of the copper melting furnace by installing the ear plate 3 and fastening the bolts 31; before assembling the oxygen analyzer body 2, press down the pressing rod 44. The pressing rod 44 drives the frustum-shaped drive block 43 to move downward and compress the reset spring 42. The drive block 43 moves down and releases the outward pushing force on the surrounding locking blocks 432, and the locking blocks 432 retract inward; then, align the insertion rod 41 with the circular groove 22 of the connecting block 21 and the circular groove 11 of the support frame 1 and insert it as a whole. After it is fully in place, release the pressing rod 44. The reset spring 42 and the tension spring 45 push the drive block 43 upward synchronously to reset. The drive block 43 pushes the locking blocks 432 outward again by relying on the inclined surface. The locking block 432 extends out and embeds into the locking groove 12 on the inner wall of the circular groove 11, thus completing the locking and locking. During the assembly process, the guide block 431 and the guide groove 46 constrain the vertical movement of the drive block 43 to prevent it from shifting. The anti-detachment slider 434 and the anti-detachment groove 435 prevent the locking block 432 from sliding off. The rotating pressure ring 412 can press the connecting block 21 tightly, and the limiting ring 413 limits the tightening limit of the pressure ring 412. When disassembling, press the pressing rod 44 down again, and the drive block 43 moves down, causing the locking block 432 to retract inward and disengage from the locking groove 12. The entire set of fixed components 4 and the oxygen analyzer body 2 can then be pulled out together. The entire process relies on a purely mechanical structure to achieve rapid disassembly and assembly, which is suitable for high-temperature and dusty working conditions in front of copper smelting furnaces.
