[0033] See also Figures 1 to 4 Two racks 304 are provided on the upper and lower sides of one end of the pull handle 303, and a rack 304 is provided on the upper side of the other end of the pull handle 303, the rack 304 is meshed with the transmission wheel 305, a slot 4 is provided on the inner side of the sleeve 306, and a return spring 5 is connected inside the sleeve 306, a block 6 is symmetrically connected to the outer side of the end of the support rod 307 close to the sleeve 306, and the block 6 is slidably connected to the sleeve 306 through the slot 4, the return spring 5 is connected to the support rod 307, and an embedding groove 7 is symmetrically provided on the outer side of the end of the support rod 307 away from the sleeve 306, and a locking ring 8 is symmetrically provided on the outer side of the support rod 307, an embedding cone 9 is connected to the inner side of the locking ring 8, a pull rope 10 is connected between the support rod 307 and the pull handle 303, the embedding cone 9 is embeddingly connected to the support rod 307 through the embedding groove 7, and the locking rings 8 are connected by bolts.

[0034] It should be noted that the pull rope 10 is made of high temperature resistant material.

[0035] When in use, according to the inner diameter of the braided sleeve, the sleeve plate 309 of the corresponding diameter is screwed into the installation groove 308, and then the two ends of the braided sleeve are sleeved on the sleeve plate 309, and then the locking ring 8 is fixed to the outside of the support rod 307 and the embedded cone 9 is used to press the braided sleeve into the embedded groove 7, so that the braided sleeve can be fixed. After the slide frame 301 is sent into the box body 1, the braided sleeve can be tested. During the testing process, the pull handle 303 can be pulled outward in the slide rail 302, and the pull handle 303 can drive the two sides through the rack 304. The transmission wheels 305 rotate synchronously in the same direction, so that the sleeve 306 drives the braided sleeve to rotate through the support rod 307 to adjust the burning point.

[0036] In summary, the above-mentioned device of the present invention can fix braided sleeves of different models and flip or twist them during detection, thereby improving the comprehensiveness of the detection.

[0037] During the inspection, the pull handle 303 is continuously pulled outward in the slide rail 302. After the rack 304 is out of contact with the transmission wheel 305, the pull handle 303 can pull the support rod 307 through the pull rope 10 to move in the sleeve 306 and compress the reset spring 5, thereby stretching the braided sleeve, so as to detect whether stretching the braided sleeve will affect its fireproof performance when burning, or whether the braided sleeve will be broken when stretched after burning. After the stretching is completed, the pull handle 303 is released, and the reset spring 5 can drive the support rod 307 to rebound and reset. When the support rod 307 moves or rebounds, the block 6 can limit the support rod 307 through the card slot 4 to prevent the support rod 307 from being deflected or escaping from the sleeve 306. When the sleeve 306 rotates, the card block 6 can make the support rod 307 rotate synchronously with the sleeve 306 through the card slot 4 to prevent the braided sleeve from being twisted or turned over. The embedded cone 9 can ensure the fixing effect of the braided sleeve through the embedded slot 7 to prevent the braided sleeve from being twisted or turned over due to loose fixation. During the detection process, the temperature sensor 310 can always detect the temperature in the braided sleeve. In summary, the braided sleeve can be stretched during use to improve the comprehensiveness of the detection.

[0039] The specific operation is as follows: when the braided sleeve is not put in, the sealing block 23 can be inserted into the slide groove 2 under the action of the closing spring 22 to close the slide groove 2 to prevent flame or toxic gas from leaking from the slide groove 2. When the braided sleeve is put in, first insert the slide frame 301 into the slide groove 2. The slide frame 301 can be pressed into the sealing groove 21 through the inclined surface of the sealing block 23, and the closing spring 22 is compressed. When the braided sleeve approaches the sealing plate 19, the sealing plate 19 is pulled up to allow the sliding frame 301 to send the braided sleeve into the box body 1. After the braided sleeve passes under the sealing plate 19, the sealing plate 19 is immediately released, and the sealing plate 19 can fall under the action of gravity to close the box body 1.

After the detection is completed, the slide frame 301 is pulled out of the slide groove 2, and the sealing block 23 can rebound quickly under the action of the closing spring 22 to close the slide groove 2 again.

[0040] In summary, when using the fire-resistant detection device for the braided fireproof sleeve, first screw the sleeve plate 309 of the corresponding diameter into the installation groove 308 according to the inner diameter of the braided sleeve, then sleeve the two ends of the braided sleeve onto the sleeve plate 309, and then fix the locking ring 8 on the outside of the support rod 307 and let the embedded cone 9 press the braided sleeve into the embedded groove 7 to complete the fixation of the braided sleeve. When the braided sleeve is not inserted, the sealing block 23 can be inserted into the slide groove 2 under the action of the closing spring 22 to close the slide groove 2 to prevent flame or toxic gas from leaking from the slide groove 2. When inserting the braided sleeve, first insert the slide frame 301 into the slide groove 2. The slide frame 301 can be pressed into the sealing groove 21 through the inclined surface of the sealing block 23, and the closing spring 22 is compressed. When the braided sleeve is close to the sealing plate 19, The sealing plate 19 is pulled up to allow the sliding frame 301 to send the braided sleeve into the box body 1. After the braided sleeve passes under the sealing plate 19, the sealing plate 19 is immediately released, and the sealing plate 19 can fall under the action of gravity to close the box body 1, and the sealing block 23 will continue to stay in the sealing groove 21. During the detection process, the pull handle 303 can be pulled outward in the slide rail 302, and the pull handle 303 can drive the transmission wheels 305 on both sides to rotate in the same direction synchronously through the rack 304, so that the sleeve 306 drives the braided sleeve to rotate through the support rod 307 to adjust the burning point, and the pull handle 303 is pushed inward in the slide rail 302, so that the pull handle 303 can drive the transmission wheels 305 on both sides to rotate synchronously in the opposite direction through the rack 304, so as to twist the braided sleeve, thereby detecting the braided sleeve. During burning, whether twisting it will affect its fireproof performance, or whether the braided sleeve will be broken if it is twisted after burning, the handle 303 is continuously pulled outward in the slide rail 302. After the rack 304 is out of contact with the transmission wheel 305, the handle 303 can pull the support rod 307 through the pull rope 10 to move in the sleeve 306 and compress the reset spring 5, thereby stretching the braided sleeve, so as to detect whether the stretching of the braided sleeve during burning will affect its fireproof performance, or whether the braided sleeve will be broken if it is stretched after burning. After the stretching is completed, the handle 303 is released, and the reset spring 5 can drive the support rod 307 to rebound and reset. When the support rod 307 moves or rebounds, the block 6 can be connected to the support rod 307 through the card slot 4. The support rod 307 is restricted to prevent the support rod 307 from being deflected or escaping from the sleeve 306. When the sleeve 306 rotates, the block 6 can make the support rod 307 rotate synchronously with the sleeve 306 through the card slot 4 to prevent the braided sleeve from being twisted or turned over. The embedded cone 9 can ensure the fixing effect of the braided sleeve through the embedded slot 7 to prevent the braided sleeve from being twisted or turned over due to loose fixation. During the detection process, the temperature sensor 310 can always detect the temperature in the braided sleeve. During the detection process, the motor 16 can drive the threaded rod 15 to rotate, so that the threaded rod 15 moves the base 12 in the shifting groove 11 through the shifting plate 14, and the position of the spray gun 13 is changed, so as to further adjust the burning point in coordination with the rotation of the braided sleeve.In order to achieve the purpose of fully burning the braided sleeve, when the braided sleeve is tested, the state of the braided sleeve can be observed through the observation port 20.
