DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 and 2 The present invention provides a steel tube skylight fireproofing device, comprising:

[0033] The protective member 100 includes at least two chain links 101 and a rotating joint 102. The chain links 101 and the rotating joint 102 are alternately arranged and connected in a chain shape. The chain links 101 can be adjusted to any curved shape by adjusting the rotating joint 102;

[0034] A protective sleeve 200 is sleeved on the outside of the chain link 101 and the rotating joint 102; and,

[0035] The hand-held rod 300 is connected to the end of the protective member 100 .

[0036] This embodiment provides a handheld fire-isolating and fire-proofing device to replace the manual operation of kneading fire-proof mud at the window opening, which is simpler and more stable to operate. Everyone can easily learn and understand the method and can use the device efficiently to perform fire-isolating, fire-proofing and fire-blocking operations at the predetermined position of the target thermal cutting.

[0037] It effectively solves the problem of material waste in traditional methods. The materials used in the device can be reused stably for a long time, reducing material waste. The convenience of the use process effectively ensures the efficiency of the operation process and enhances the coordination with thermal cutting work.

[0038] The design is equipped with a hand-held grip, a detachable positioning auxiliary rod, etc., which ensures the effectiveness of fire isolation, fire prevention and fire resistance during the operation process, avoids personally approaching the hot cutting position and flames with hands, and significantly improves the safety of the operation process.

[0039] Specifically, the shape of the chain link 101 can be adjusted through the rotating joint 102 according to the shape and size of the window, so that it can be adapted to the window and meet various operating requirements.

[0040] In one embodiment, see Figure 3 A fireproof cover 201 is provided at the front end of the protective cover 200 . The fireproof cover 201 is arranged along the upper edge of the protective cover 200 , and the inner surface of the fireproof cover 201 is an arc-shaped structure extending toward the front side of the end of the protective cover 200 .

[0041] The present embodiment is configured in this way. Since the window opening is operated by a cutting device, an uncontrollable flame will be ejected during the window opening process. The ejected flame will spread irregularly to the surroundings, which may cause burns to the hand-held position. By providing a fireproof cover 201 at the front end of the protective cover 200, the flame at the window opening position can be prevented from spreading to the hand-held end, thereby improving the protection performance for the operator and further improving safety.

[0042] In one embodiment, see Figure 6 , and also includes an annular tube 400, which has a through hole 401, and the protective member 100 can pass through the through hole 401 and be movably arranged in the annular tube 400, and the annular tube 400 has an arc groove 402, and the arc groove 402 has a shift block 403 connected to the end of the protective member 100.

[0043] This embodiment is configured such that the protective sleeve 200 can be accommodated through the configuration of the annular tube 400, which can provide a certain degree of protection for the protective sleeve 200 when it is not in use. At the same time, it is stored in the annular tube 400 for easy storage and movement. When it is used later, the protective sleeve 200 can be pushed out of the annular tube 400 by pushing the shift block 403 along the arc groove 402 until it is pushed out to a suitable length.

[0044] In one embodiment, see Figure 6 A stopper 404 is provided on the annular tube 400 and is located outside the through hole 401. The stopper 404 is an arc-shaped block, and a pressing rod 405 is provided on the surface of the annular tube 400 on the opposite side of the stopper 404. The pressing rod 405 performs a reciprocating linear motion toward the outer area of ​​the through hole 401 to press and shape the chain link 101 and the rotating link 102 pulled out of the annular tube 400.

[0045] The present embodiment is configured in this way. Since the position and size of each window opening in the pipeline may be different, and the chain link 101 can be adjusted to different shapes using the rotating joint 102, when the protective sleeve 200 is pulled out of the annular tube 400, the pressing rod 405 is controlled to move linearly so that its end presses and shapes the protective sleeve 200, so that the overall shape of the protective sleeve 200 adapts to the shape and size of the current window opening position, and the operation is simple and quick.

[0046] In one embodiment, see Figure 7 Two clamping blocks 406 are provided at the through hole 401, and the two clamping blocks 406 can be close to or far away from each other, and a sponge block 407 is provided on the clamping surface of the clamping block 406. A paddle 408 connected to the clamping block 406 is provided on the surface of the annular tube 400, and the paddle 408 is slidably embedded in the annular tube 400.

[0047] This embodiment is configured such that when the window opening operation is completed and the protective cover 200 is stored in the annular tube 400, the paddle 408 is pushed to drive the two clamping blocks 406 to drive the sponge block 407 to contact the outer surface of the protective cover 200, so that impurities on the outer surface of the protective cover 200 during the operation can be filtered out, which can not only maintain the protective cover 200, but also avoid problems affecting the performance of the protective cover 200 during subsequent window opening operations.

[0048] In one embodiment, see Figure 6 One end of the pressing rod 405 is connected to the hand-held rod 300, and the other end passes through a guide sleeve 409 provided on the annular tube 400 and can be detachably provided. The pressing rod 405 is a telescopic structure, and a groove for accommodating the pressing rod 405 is provided on the surface of the hand-held rod 300.

[0049] This embodiment is configured such that the pressing rod 405 can be pulled out and passed through the guide sleeve 409 for operation when in use. After use, the pressing rod 405 is pulled out and stored in the groove on the hand-held rod 300 for easy storage and movement. At the same time, the guide sleeve 409 can guide the pressing rod 405 to ensure that the protective cover 200 can be directionally shaped each time it is operated, thereby improving the shaping effect and efficiency.

[0050] In one embodiment, see Figure 5An auxiliary sleeve rod 301 is sleeved on the outside of the hand-held rod 300, an external thread is provided on the surface of the hand-held rod 300, and a limiting button 302 for limiting the auxiliary sleeve rod 301 is provided at the end of the hand-held rod 300, and the outer surface of the hand-held rod 300 is coated with flame-retardant silicone.

[0051] This arrangement of the present embodiment facilitates adjustment of the overlap between the auxiliary sleeve rod 301 and the hand-held rod 300 as needed, thereby achieving adjustment of the hand-held operating length, improving the practicality of the device, and being able to adapt to and adjust the operating length of the hand-held rod 300 according to different usage habits, with good use effect.

[0052] In one embodiment, see Figure 4 Two rows of parallel and equidistantly distributed magnetic beads 202 are arranged in the interlayer of the protective sleeve 200. The length of the magnetic beads 202 is equal to that of the protective sleeve 200, and the protective sleeve 200 between the two rows of magnetic beads 202 is in an arc-shaped surface structure. This embodiment is arranged in this way. Through the arrangement of the magnetic beads 202, the fit between the protective sleeve 200 and the pipeline can be improved during use, ensuring that the flame generated by cutting will not overflow to the surroundings, reducing risks, improving safety, and further ensuring the fire isolation, fire prevention, and fire retardation effects.

[0053] In one embodiment, the chain link 101 and the rotating joint 102 are filled with flame-retardant and high-temperature resistant natural sand.

[0054] The protective cover 200 is made of fire-resistant, high-temperature-resistant and flame-retardant silicone fireproof fabric.

[0055] This configuration of the present embodiment can ensure that the flexibility of the device during use fully meets the requirements of the operating scene and has fire isolation and fire prevention performance.

[0056] It should be noted that if the embodiments of the present invention involve directional indications such as up, down, left, right, front, back, etc., then the directional indications are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture as shown in the accompanying drawings. If the specific posture changes, the directional indication will also change accordingly.
