[0022] In the prior art, when a stress corrosion testing device conducts a stress corrosion test on a material sample, the sample is in a fixed position inside the testing device, which is not convenient for multiple immersion and multiple drying treatments of the sample, making it unable to meet the test environment requirements in various situations, resulting in poor effectiveness of the test results.

[0023] In order to solve the above technical problems, the present invention provides a stress corrosion testing device capable of preheating and maintaining a constant temperature.

[0024] See also Figure 1-3 In one embodiment of the present invention, the stress corrosion testing device comprises: A reactor 100, wherein the interior of the reactor 100 carries a corrosive solution; A preheating mechanism (not shown in the drawings) is installed inside the reactor 100; the preheating mechanism is used to control the temperature of the corrosive solution; A clamp mechanism 200, which is used to install and fix a sample (not shown in the drawings); The adjusting mechanism 300 is installed inside the reactor 100 and is connected to the clamping mechanism 200. The adjusting mechanism 300 is used to drive the clamping mechanism 200 to move up and down so that the sample is immersed in the corrosion solution, or the sample is separated from the corrosion solution for drying.

[0025] The technical solution of the present invention is to set a preheating mechanism, a clamping mechanism 200 and an adjusting mechanism 300 in the reactor 100; the preheating mechanism can be used to control the temperature of the corrosion solution in the reactor 100, so that the temperature in the reactor 100 is more uniform, the temperature of the corrosion solution is accurately controlled, and the interference of the corrosion solution temperature factor on the test results is eliminated; the clamping mechanism 200 is used to clamp samples of different sizes, and the samples can be controlled to perform various forms of movement such as stretching, compression, rotation and kinking in the corrosion solution, so as to test the fatigue life of the test material under various motion states; the adjusting mechanism 300 is used to drive the clamping mechanism 200 to perform lifting movement, so as to control the sample on the clamping mechanism 200 to be immersed in the corrosion solution or to be separated from the corrosion solution for drying, so as to realize multiple immersion and multiple drying treatments of the sample, so that it can meet the test environment requirements of various situations and ensure the validity of the test results.

[0026] There are many specific structures of the reactor 100. Figure 1 The reactor 100 includes a rectangular reactor body 110, and a top cover 120 is detachably connected to the top opening of the reactor body 110. With this arrangement, when the sample needs to be dried, the top cover 120 can be removed to improve the drying efficiency of the sample after it is separated from the corrosive solution.

[0027] Further, see Attachment Figure 2 A liquid inlet pipe 150 and a liquid discharge pipe 160 are respectively arranged on opposite sides of the kettle body 110. The kettle body 110 is connected to an external liquid storage tank (not shown in the drawings) through the liquid inlet pipe 150 and the liquid discharge pipe 160. The liquid storage tank stores a corrosive solution. In this arrangement, the liquid inlet pipe 150 is used to inject the corrosive solution into the kettle body 110, and the liquid discharge pipe 160 is used to discharge the corrosive solution in the kettle body 110. A circulating pipeline with a circulating pump can be connected between the liquid inlet pipe 150 and the liquid discharge pipe 160 to realize the circulation of the corrosive solution between the kettle body 110 and the liquid storage tank.

[0028] Further, see Attachment Figure 1 A material taking-in and discharging port 130 is provided in the middle of the kettle body 110, and an opening and closing door (not shown in the drawings) is movably connected to the material taking-in and discharging port 130; and an observation window (not shown in the drawings) is provided on the opening and closing door; in this way, the material taking-in and discharging port 130 can be used to install and place the sample on the clamp mechanism 200, or remove the sample from the clamp mechanism 200; the observation window can facilitate the test personnel to observe the test status of the sample in the kettle body 110 from the outside.

[0029] There are many specific structures of the preheating mechanism. In this embodiment, the preheating mechanism includes an electric heating tube (not shown in the drawings), which is installed at the inner bottom of the reactor 100. In this arrangement, the corrosion solution is heated by the common electric heating tube on the market, which has a simple structure and strong practicality.

[0030] There are many specific structures of the adjustment mechanism 300. Figure 5-7 The adjustment mechanism 300 includes a fixed hanger 310 and a movable hanger 320, the fixed hanger 310 is located above the movable hanger 320; the fixed hanger 310 is fixedly connected to the reactor 100; a plurality of first telescopic devices 330 are arranged between the fixed hanger 310 and the movable hanger 320, and the first telescopic devices 330 are used to drive the movable hanger 320 to move up and down relative to the fixed hanger 310; the middle part of the movable hanger 320 is rotatably connected with a turntable assembly 340, and the turntable assembly 340 is connected to the clamp mechanism 200. In this way, the fixed hanger 310 is fixedly connected to the reactor 100, so that the fixed hanger 310 serves as the fulcrum for the first telescopic device 330 to drive the movable hanger 320 to move up and down; when the first telescopic device 330 is started, it can drive the movable hanger 320 to move up and down, thereby driving the clamp mechanism 200 connected to the turntable assembly 340 to move up and down together, so as to control the sample to be immersed in the corrosive solution or to be separated from the corrosive solution for drying, so as to meet the test environment requirements of various situations. Among them, the above-mentioned first telescopic device 330 can be selected as an electric telescopic rod, and this application does not make specific restrictions on it.

[0031] Further, see Attachment Figure 7 The turntable assembly 340 includes a turntable body 347 rotatably connected to the middle position of the movable hanger 320, wherein the edge of the turntable body 347 is surrounded by a conical gear ring 341; the center position of the turntable body 347 is fixedly connected to a vertically arranged center column 342, the top of the center column 342 is rotatably connected to an adjusting nut 343, the inner thread of the adjusting nut 343 is connected to the lower end of the adjusting screw 344, and the upper end of the adjusting screw 344 is rotatably connected to a top seat 345; the adjustment mechanism 300 also includes a turntable rotating assembly 350, which is used to drive the turntable body 347 to rotate relative to the movable hanger 320. In this way, the turntable rotating assembly 350 is used to drive the turntable body 347 to rotate, so that the clamp mechanism 200 connected to the turntable body 347 drives the sample to rotate accordingly, so as to facilitate the sample to be thrown off the corrosive solution after it is separated from the corrosive solution, so as to improve the drying efficiency and reduce the influence of the corrosive solution on the test accuracy during the drying process.

[0032] Specifically, refer to the attached Figure 7The turntable rotating assembly 350 includes a first connecting rod 351, a first push-pull frame 352, a first rotating shaft 353 and a first rotating tube 354; wherein the upper end of the first connecting rod 351 is rotatably connected to the top seat 345, and the lower end of the first connecting rod 351 is rotatably connected to the first push-pull frame 352; the first push-pull frame 352 is rotatably connected to the first end of the first rotating shaft 353, and the second end of the first rotating shaft 353 is slidably sleeved inside the first end of the first rotating tube 354, and the second end of the first rotating shaft 353 is rotatably connected to the first rotating tube 354. The first end of the first rotating tube 354 has a concave-convex matching structure (not shown in the drawings); the second end of the first rotating tube 354 is provided with a first gear ring 356, and the first gear ring 356 is used to mesh with the vertical rack 140 fixed inside the reactor 100; the middle part of the first rotating shaft 353 is provided with a first bevel gear 357, and the first bevel gear 357 is used to mesh with the conical gear ring 341 of the rotating disk body 347; in this way, when the movable hanger 320 is controlled by the first telescopic device 330 to move up and down, The movable hanger 320 drives the first rotating tube 354 to move up and down indirectly through the first connecting rod 351, the first push-pull frame 352 and the first rotation. When the first rotating tube 354 moves up and down, it drives the first gear ring 356 at its second end to mesh with the vertical rack 140 located on the inner wall of the reactor 100, thereby driving the first gear ring 356 to rotate around its own axis. When the first gear ring 356 rotates, it can drive the first rotating tube 354 to rotate; because the second end of the first rotating shaft 353 is connected to the first rotating tube There is a concave-convex matching structure between the first ends of 354, so that when the first rotating tube 354 rotates, the first rotating shaft 353 is driven to rotate through its concave-convex matching structure, and when the first rotating shaft 353 rotates, it drives the first bevel gear 357 to rotate. When the first bevel gear 357 engages with the conical ring gear 341 on the turntable body 347, it can drive the conical ring gear 341 to rotate, thereby driving the turntable body 347 to rotate around its own axis, thereby driving the clamp mechanism 200 and the sample on the clamp mechanism 200 to rotate.

[0033] Among them, whether the first bevel gear 357 is meshed with the bevel gear ring 341 can be controlled by rotating the adjusting nut 343; when the adjusting nut 343 is rotated, the adjusting screw 344 is driven to move up and down along the center column 342; when the adjusting screw 344 drives the top seat 345 to move upward, the top seat 345 pulls the first push-pull frame 352 to move toward the axial direction of the turntable body 347 through the first connecting rod 351, thereby pulling the first rotating shaft 353 to slide out to the outside of the first rotating tube 354 through the first push-pull frame 352. The length becomes longer, and finally the first bevel gear 357 is controlled to be meshed and connected with the bevel gear ring 341; conversely, when the adjusting screw 344 drives the top seat 345 to move downward, the length of the first rotating shaft 353 sliding out to the outside of the first rotating tube 354 becomes shorter, and at this time the first bevel gear 357 and the bevel gear ring 341 are separated from each other.

[0034] Further, see Attachment Figure 6-7 The movable hanger 320 is provided with a first support 321, and the first rotating tube 354 is rotatably installed in the first support 321. In this arrangement, the first support 321 is used as a supporting mounting platform for the first rotating tube 354 to ensure that the first rotating tube 354 can be stably arranged on the movable hanger 320.

[0035] Among them, the above-mentioned concave-convex matching structure includes a convex ridge arranged on the outside of the first rotating shaft 353, and a groove arranged on the inside of the first rotating tube 354, and the concave-convex fitting connection between the ridge and the groove is utilized to realize that the first rotating tube 354 can drive the first rotating shaft 353 to rotate; wherein the groove direction of the groove is arranged parallel to the axial direction of the first rotating tube 354 to ensure that the first rotating shaft 353 can slide along the axial direction of the first rotating tube 354.

[0036] There are many specific structures of the clamp mechanism 200. Figure 7-8The clamp mechanism 200 includes a second telescopic device 210 fixed on the turntable body 347, the driving end of the second telescopic device 210 is connected to the lifting seat 220, and the lifting seat 220 is slidably sleeved on the central column 342; the clamp assemblies 230 are symmetrically arranged at the opposite ends of the lifting seat 220; each clamp assembly 230 includes an oblique connecting rod 231, a sliding hanger 232 and a mounting seat 233; the upper end of the oblique connecting rod 231 is rotatably connected to the lifting seat 220, and the lower end of the oblique connecting rod 231 is rotatably connected to the upper end of the sliding hanger 232; The sliding hanger 232 passes through the turntable body 347; two upper and lower limit rings 2321 are fixedly provided in the middle of the sliding hanger 232, and the two limit rings 2321 respectively abut the top side and the bottom side of the turntable body 347, and the area between the two limit rings 2321 is defined as a sliding area 2322, and the sliding area 2322 is slidably connected to the turntable slide 346 radially arranged on the turntable body 347; the mounting seat 233 is connected to the lower end of the sliding hanger 232, and the mounting seat 233 is used to fix one end of the sample. With such arrangement, the second telescopic device 210 can drive the lifting seat 220 to slide in the up and down directions along the central column 342, so that the angle between the oblique connecting rods 231 located on both sides thereof can be increased or decreased through the lifting seat 220, and then the oblique connecting rods 231 can drive the sliding hanger 232 to slide toward or away from each other in the turntable slideway 346 of the turntable body 347; wherein, since two upper and lower limit retaining rings 2321 are fixedly arranged in the middle part of each sliding hanger 232, and the two limit retaining rings 2321 respectively abut the top side and the bottom side of the turntable body 347, they play a role of blocking and limiting, so as to ensure that only the sliding area 2322 of the sliding hanger 232 can slide in the turntable slideway 346; the lower end of the sliding hanger 232 is connected to the mounting seat 233, and one end of the sample is fixed by the mounting seat 233; it can be understood that since the clamp assemblies 230 are arranged in pairs, the two ends of the sample are respectively fixed on the mounting seats 233 on both sides. The mounting seat 233 and the sample can be fixed to each other by bolts and nuts, which is not specifically limited in this application. The second telescopic device 210 can be an electric telescopic rod, which is not specifically limited in this application.

[0037] It can be understood that when the second telescopic device 210 drives the lifting seat 220 to move upward along the central column 342, the angle between the oblique links 231 on both sides becomes smaller, and the sliding hangers 232 on both sides slide toward each other in the turntable slide 346 of the turntable body 347, and the sample can be squeezed at this time; a pressure sensor can be installed on the mounting seat 233 to test the fatigue life of the sample during squeezing; when the second telescopic device 210 drives the lifting seat 220 to move downward along the central column 342, the angle between the oblique links 231 on both sides becomes larger, and the sliding hangers 232 on both sides slide away from each other in the turntable slide 346 of the turntable body 347, and the sample can be stretched at this time; a pressure sensor can be installed on the mounting seat 233 to test the fatigue life of the sample during stretching.

[0038] Further, see Attachment Fig. 9 , a rotation drive motor 280 is arranged inside the central column 342; a transmission shaft 240 is arranged between the two mounting seats 233 and the central column 342, and the first end of the transmission shaft 240 passes through the through hole 3421 of the central column 342 and extends to the interior of the central column 342 and is connected to the driving end of the rotation drive motor 280; under the drive of the rotation drive motor 280, the rotation directions of the transmission shafts 240 on both sides are opposite; a transmission sleeve 250 is rotatably connected to the sliding hanger 232, and the transmission shaft The second end of the rod 240 slides through the transmission sleeve 250, and a concave-convex matching structure is provided between the transmission shaft 240 and the transmission sleeve 250 (not shown in the drawings); a driving wheel 261 is fixedly sleeved on the outer side of the transmission sleeve 250, and a driven wheel 262 is rotatably connected to the lower end of the sliding hanger 232, and the driving wheel 261 and the driven wheel 262 are connected through a synchronous belt 263; a rotating shaft 270 is fixedly connected at the center of the driven wheel 262, and the other end of the rotating shaft 270 is fixedly connected to the mounting seat 233. With such a configuration, the rotary drive motor 280 is used to drive the transmission shafts 240 on both sides to rotate in different directions. Since there is a concave-convex matching structure between the transmission shaft 240 and the transmission sleeve 250, the transmission sleeve 250 can rotate along with the transmission shaft 240; the rotation of the transmission sleeve 250 drives the driving wheel 261 to rotate. Since the driving wheel 261 and the driven wheel 262 are connected by the synchronous belt 263, the driven wheel 262 can rotate along with the driving wheel 261; the rotation of the driven wheel 262 drives the rotating shaft 270 to rotate, thereby rotating the mounting seat 233. Since the two transmission shafts 240 rotate in opposite directions, the mounting seats 233 on both sides also rotate in opposite directions, so that the samples between the mounting seats 233 on both sides are subjected to a kink test to meet the test requirements of various situations; In addition, the two transmission shafts 240 can not only play a transmission role, but also a guiding and balancing role; they can enhance the stability of the sliding hanger 232 when sliding toward or away from each other in the turntable slide 346 of the turntable body 347, thereby improving the stability of the sample when it is compressed or stretched.

[0039] Specifically, refer to the attached Fig. 9 The driving end of the rotary drive motor 280 is connected to a center bevel gear 281, and the first end of the transmission shaft 240 is connected to a side bevel gear 241, and the center bevel gear 281 is meshingly connected with the side bevel gear 241; in this way, the rotary drive motor 280 drives the transmission shaft 240 to rotate through the meshing connection between the center bevel gear 281 and the side bevel gear 241, and the structure is simple and practical.

[0040] Among them, a sealant layer (not shown in the drawings) is provided at the connection between the transmission shaft 240 and the center column 342 to ensure that the corrosive solution will not penetrate into the center column 342 through the connection gap between the transmission shaft 240 and the center column 342, so as to cause the rotating drive motor 280 located inside the center column 342 to be corroded and damaged by the corrosive solution.

[0041] Among them, the above-mentioned concave-convex matching structure includes a ridge arranged on the outside of the transmission shaft 240, and a groove arranged on the inside of the transmission sleeve 250, and the concave-convex fitting connection between the ridge and the groove is utilized to realize that the transmission shaft 240 can drive the transmission sleeve 250 to rotate; wherein the groove direction of the groove is arranged parallel to the axial direction of the transmission sleeve 250 to ensure that the transmission shaft 240 can slide along the axial direction of the transmission sleeve 250.

[0042] As a preferred solution of the above embodiment, refer to the attached Figure 2-3A storage horizontal box 400 is symmetrically arranged at the middle position of the inner side of the reactor 100, and a sealing slide 500 is slidably connected to the inside of the storage horizontal box 400, and the sealing slide 500 can slide to a first position and a second position relative to the storage horizontal box 400; when the sealing slide 500 slides to the first position, the sealing slide 500 is stored in the storage horizontal box 400; when the sealing slide 500 slides to the second position, the sealing slide 500 extends out of the storage horizontal box 400, and the ends of the sealing slides 500 located on both sides are fitted together; a slide displacement assembly 600 is arranged between the movable hanger 320 and the sealing slide 500, and the left and right sides of the movable hanger 320 are respectively connected to the sealing slide 500 on the corresponding side through the slide displacement assembly 600; when the movable hanger 320 is lifted and lowered, the sealing slide 500 is driven to move between the first position and the second position through the slide displacement assembly 600. In this way, the movable hanger 320 and the sealing slide 500 are linked to each other through the slide displacement assembly 600; when the sample needs to be immersed in the corrosive solution, while the movable hanger 320 moves downward, the sealing slides 500 on both sides are moved to the first position through the slide displacement assembly 600, so that the clamp mechanism 200 can pass through the gap between the sealing slides 500 on both sides and immerse the sample in the corrosive solution; when the sample needs to be dried, while the movable hanger 320 moves upward, the sealing slides 500 on both sides are moved to the second position through the slide displacement assembly 600, so that the sample and the corrosive solution are separated by the sealing slide 500, thereby preventing the corrosive solution from volatilizing into the air of the drying sample and affecting the test effect of the sample. In addition, since the movable hanger 320 and the sealing slide 500 are linked to each other, the correlation of each mechanism in the reactor 100 is improved, and there is no need to set up an additional driving device for driving the sealing slide 500 to move.

[0043] Specifically, the slide displacement assembly 600 includes a telescopic link 610, a storage sleeve 620 and a linkage frame 630; the movable hanger 320 is rotatably connected to the upper end of the telescopic link 610, the lower end of the telescopic link 610 slides in the storage sleeve 620, and a limiting spring 640 is arranged between the lower end of the telescopic link 610 and the storage sleeve 620; the lower end of the telescopic link 610 is connected to a limiting block 611, the storage sleeve 620 is provided with a lower limiting slide 621, and the limiting block 611 is slidably connected to the limiting slide 621; the end of the storage sleeve 620 away from the telescopic link 610 is rotatably connected to the linkage frame 630; a connecting bracket 631 is arranged in the middle of the linkage frame 630, the connecting bracket 631 slides in the limiting slide groove 410 of the storage cross box 400, and is fixedly connected to the sealing slide 500, wherein the groove direction of the limiting slide groove 410 is the same as the displacement direction of the sealing slide 500.

[0044] So set up, When the sample needs to be dried, the movable hanger 320 moves upward and drives one end of the telescopic connecting rod 610 to move upward, so that the telescopic connecting rod 610 gradually slides outward along the storage sleeve 620 and gradually releases the compression of the limit compression spring; when the clamp mechanism 200 moves to above the two sealing slide plates 500, the limit block 611 on the telescopic connecting rod 610 is clamped at the end position of the limit slideway 621 of the storage sleeve 620. At this time, as the movable hanger 320 continues to move upward, the telescopic connecting rod 610 drives one end of the storage sleeve 620 to move upward through the limit block 611, and the other end of the storage sleeve 620 is rotatably connected to the linkage frame 630. The connecting bracket 631 of the linkage frame 630 slides along the limit slide groove 410 and drives the sealing slide plate 500 to slide out of the storage horizontal box 400, and makes the sealing slide plates 500 on both sides gradually fit together; When the sample needs to be immersed in the corrosive solution, the movable hanger 320 moves downward and can generate thrust on the storage sleeve 620 through the cooperation of the telescopic connecting rod 610 and the limit compression spring. The storage sleeve 620 drives the sealing slide 500 to slide into the two storage horizontal boxes 400 through the connecting bracket 631 of the linkage frame 630; and as the movable hanger 320 continues to move downward, it drives the telescopic connecting rod 610 to compress the limit compression spring.

[0045] Further, see Attachment Fig.10 A guide slope 510 is provided at one end of the sealing slide 500 away from the storage horizontal box 400, and a guide hole 520 is provided in the middle position of the guide slope 510; a sealing plate 530 is provided on the side of the sealing slide 500 facing the corrosive solution, the first end of the sealing plate 530 is rotatably connected to the sealing slide 500, and the second end of the sealing plate 530 is used to block the guide hole 520; a groove-shaped slide 531 is provided at the center of the sealing plate 530, and the groove-shaped slide 531 slides in the middle of the vertical shaft 532, the top end of the vertical shaft 532 is fixed on the sealing slide 500, and a limiting ring 533 is fixed at the bottom end of the vertical shaft 532, and a reset compression spring 534 is sleeved on the shaft body of the vertical shaft 532 located between the limiting ring 533 and the blocking plate 530. In this way, the sealing slide plate 500 is provided with a guide slope 510 at one end away from the storage horizontal box 400. When the sample is dried, the corrosive solution thrown off or dripped from the sample falls on the sealing slide plate 500, and can fall into the guide hole 520 through the guide slope 510, and generate pressure on the blocking plate 530 under the gravity of the corrosive solution. The blocking plate 530 slides on the vertical axis 532 through the groove slide 531, and compresses the reset spring 534, so that the blocking plate 530 flips downward and opens, thereby realizing the falling and collection of the corrosive solution, and reducing the volatilization amount of the corrosive solution into the air of the drying sample; when the corrosive solution falls, the blocking plate 530 is reset under the elastic force of the reset spring 534, and is re-sealed under the guide hole 520 to prevent the corrosive solution below from volatilizing into the air of the drying sample.

[0046] As a preferred solution of the above embodiment, refer to the attached Figure 6-7 The stress corrosion test device also includes a wind blowing component 700, which is used to blow air to the sample; the wind blowing component 700 includes a second connecting rod 710, a second push-pull frame 720, a second rotating shaft 730, a second rotating tube 740, a fan transmission component 750 and a swirl fan 760; wherein the upper end of the second connecting rod 710 is rotatably connected to the top seat 345, and the lower end of the second connecting rod 710 is rotatably connected to the second push-pull frame 720; the second push-pull frame 720 rotates The first end of the second rotating shaft 730 is connected, and the second end of the second rotating shaft 730 is slidably sleeved inside the first end of the second rotating tube 740, and a concave-convex matching structure is provided between the second end of the second rotating shaft 730 and the first end of the second rotating tube 740; a second bevel gear 770 is sleeved on the middle part of the second rotating shaft 730, and the second bevel gear 770 is used to mesh with the conical gear ring 341 of the rotating disk body 347; a second gear ring 780 is provided at the second end of the second rotating tube 740; the second gear ring 780 drives the swirl fan 760 to rotate through the fan transmission assembly 750, wherein the blowing end of the swirl fan 760 faces the sample; with such a configuration, when the second bevel gear 770 is engaged with the conical gear ring 341 fixed on the turntable body 347, the rotation of the conical gear ring 341 can drive the second bevel gear 770 to rotate, and the rotation of the second bevel gear 770 can drive the second rotating shaft 730 to rotate; since there is a concave-convex matching structure between the second end of the second rotating shaft 730 and the first end of the second rotating tube 740, the rotation of the second rotating shaft 730 can drive the second rotating tube 740 to rotate, and the rotation of the second rotating tube 740 drives the second gear ring 780 to rotate, and the second gear ring 780 drives the swirl fan 760 to rotate through the fan transmission assembly 750; since the blowing end of the swirl fan 760 faces the sample, the sample of the clamping mechanism 200 is blown to a certain extent, which is beneficial to improving the drying efficiency of the sample and improving the effect of throwing off the corrosive solution on the sample.

[0047] Among them, whether the second bevel gear 770 is meshed with the bevel gear ring 341 can be controlled by rotating the adjusting nut 343; when the adjusting nut 343 is rotated, its contact position with the adjusting screw 344 can be changed, thereby driving the adjusting screw 344 to move in the up and down directions along the center column 342; when the adjusting screw 344 drives the top seat 345 to move upward, the top seat 345 pulls the second push-pull frame 720 to move toward the axial direction of the turntable body 347 through the second connecting rod 710, thereby pulling the second push-pull frame 720 to slide out the length of the second rotating shaft 730 to the outside of the second rotating tube 740 to be longer, and finally controlling the second bevel gear 770 to be meshed and connected with the bevel gear ring 341; conversely, when the adjusting screw 344 drives the top seat 345 to move downward, the length of the second rotating shaft 730 to slide out to the outside of the second rotating tube 740 is shortened, and at this time the second bevel gear 770 and the bevel gear ring 341 are separated from each other.

[0048] Since the adjustment method for whether the second bevel gear 770 is meshing with the bevel gear ring 341 is the same as the adjustment method for whether the first bevel gear 357 is meshing with the bevel gear ring 341, in actual operation, when the adjusting screw 344 drives the top seat 345 to move upward, it can drive the first bevel gear 357 and the second bevel gear 770 to move synchronously.

[0049] Among them, the above-mentioned concave-convex matching structure includes a convex ridge arranged on the outside of the second rotating shaft 730, and a groove arranged on the inside of the second rotating tube 740, and the concave-convex fitting connection of the ridge and the groove is utilized to realize that the second rotating tube 740 can drive the second rotating shaft 730 to rotate; wherein the groove direction of the groove is arranged parallel to the axial direction of the second rotating tube 740 to ensure that the second rotating shaft 730 can slide along the axial direction of the second rotating tube 740.

[0050] Further, the movable hanger 320 is provided with a second support 322, and the second rotating tube 740 is rotatably installed in the second support 322. In this arrangement, the second support 322 is used as a supporting mounting platform for the second rotating tube 740 to ensure that the second rotating tube 740 can be stably arranged on the movable hanger 320.

[0051] Specifically, the fan transmission assembly 750 includes a first transmission rod 751 arranged vertically and a second transmission rod 752 arranged horizontally. The upper end of the first transmission rod 751 is provided with a first transmission bevel gear 753, which is meshed and connected with the second gear ring 780; the lower end of the first transmission rod 751 is provided with a second transmission bevel gear 754; one end of the second transmission rod 752 is provided with a third transmission bevel gear 755, which is meshed and connected with the second transmission bevel gear 754; the other end of the second transmission rod 752 is fixedly connected with a swirl fan 760. In this way, the meshing cooperation between the first transmission bevel gear 753 and the second gear ring 780, and the meshing cooperation between the third transmission bevel gear and the second transmission bevel gear 754 is utilized to realize that the second rotating tube 740 can indirectly drive the swirl fan 760 to rotate, so as to ensure the smooth implementation of this embodiment.

[0052] Furthermore, the movable hanger 320 is provided with a third support 323, and the first transmission rod 751 and the second transmission rod 752 are rotatably mounted in the third support 323. In this arrangement, the third support 323 is used as a support and mounting platform for the first transmission rod 751 and the second transmission rod 752 to ensure that the first transmission rod 751 and the second transmission rod 752 can be stably arranged on the movable hanger 320.
