[0002] In the field of pipeline engineering, in order to ensure the heat insulation, flame retardancy and corrosion resistance of pipelines, it is usually necessary to install a protective structure on the outside of the pipeline. Especially for air conditioning ducts, hot water pipes, outdoor overhead pipes, etc., the external protective structure must meet multiple requirements such as heat insulation, sealing and easy installation. At present, the external protection of pipelines is mostly made of flame retardant and heat insulation materials such as melamine cotton, and is installed and fixed with fasteners such as cable ties, Velcro, and tape.

[0003] Existing technologies typically employ methods such as cable ties, Velcro fasteners, and aluminum foil tape sealing to ensure the stability and protective effect of the wrapping. While traditional cable ties can tighten and secure the wrapping garment and achieve a good seal, they need to be cut during disassembly, making them disposable and costly. Velcro fasteners leave gaps at the joints of the wrapping garment, resulting in a mediocre seal and requiring secondary sealing with aluminum foil tape. Furthermore, securing the wrapping garment requires sequential fixing in both radial and curved directions, making the process cumbersome. Utility Model Content

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example 1, referring to Figure 1 and Figure 2 This is the first embodiment of the present utility model. This embodiment provides an external protection structure for a pipeline. The external protection structure for a pipeline includes a wrapping component 1 and a fastening and adjusting component 2. By setting the wrapping component 1 and the fastening and adjusting component 2, the openings in two directions can be sealed simultaneously without the need for step-by-step operation, saving the trouble of manual fixation afterward and improving installation efficiency.

[0029] Specifically, the wrapping component 1 includes a wrapping garment 11. A first Velcro female side 14 is fixed to one side of the top of the wrapping garment 11, a first Velcro female side 19 is fixed to one side of the bottom of the wrapping garment 11, and a tightening strap 12 is fixed to both sides of the wrapping garment 11. A drawstring 15 is provided inside the tightening strap 12, and a toothed strap 16 is fixed to one end of the drawstring 15.

[0030] Specifically, the fastening and adjusting assembly 2 is located on one side of the wrap 11 and includes a fixing shell 21 fixed to the other end of the tether 15. The bottom of the fixing shell 21 is threaded with a bolt 23, and the top of the inner cavity of the fixing shell 21 is provided with a locking tooth 24. The top of the fixing shell 21 is fixed with a mounting shell 22, and the inner cavity of the mounting shell 22 is provided with a clamping member 26.

[0031] Example 2, refer to Figures 2-5 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0032] Specifically, it also includes an external protection structure for the pipeline, which includes a wrapping assembly 1, including a wrapping garment 11, a first Velcro female face 14 fixed to one side of the top of the wrapping garment 11, a first Velcro female face 19 fixed to one side of the bottom of the wrapping garment 11, a tightening band 12 fixed to both sides of the wrapping garment 11, a tie 15 provided inside the tightening band 12, a toothed band 16 fixed to one end of the tie 15, and a fastening and adjusting assembly 2, which is located on one side of the wrapping garment 11, including a fixing shell 21 fixed to the other end of the tie 15, a bolt 23 threadedly connected to the bottom of the fixing shell 21, a locking tooth 24 provided at the top of the inner cavity of the fixing shell 21, a mounting shell 22 fixed to the top of the fixing shell 21, and a clamping member 26 provided in the inner cavity of the mounting shell 22.

[0033] Specifically, a pre-drilled hole 13 is provided at the center of the top of the wrap 11. A second hook and loop fastener female side 17 is fixed to one side of the pre-drilled hole 13, and a second hook and loop fastener female side 18 is fixed to the other side of the pre-drilled hole 13.

[0034] Specifically, anti-slip plates 110 are fixed on both sides of the bottom of the wrapping garment 11, and the surface of the toothed belt 16 is provided with several evenly arranged teeth. The locking teeth 24 engage with the teeth, and the teeth are spaced at the same distance and are set at an angle, so that the toothed belt 16 can be inserted in the forward direction and locked in the reverse direction, achieving the same effect as a cable tie. The wrapping garment 11 is made of melamine cotton.

[0035] Specifically, one end of the bolt 23 is fixed with an anti-slip knob, and the other end of the bolt 23 is fixed with a rotating wheel 231. The inner sides of the fixed housing 21 are provided with sliding grooves 25. The anti-slip knob can provide friction for the user's hand, making it easier to rotate the bolt 23 and facilitate operation.

[0036] Specifically, slide plates 241 are fixed on both sides of the locking tooth 24. The surface of the slide plate 241 is slidably connected to the inner wall of the slide groove 25. One side of the slide plate 241 is located outside the fixed shell 21. The slide plate 241 allows the locking tooth 24 to move only in a specified direction, thereby improving its stability during movement.

[0037] Specifically, a first spring 242 is fixed to the bottom of the slide plate 241. The first spring 242 is fixed to the bottom of the inner cavity of the fixed shell 21. The first spring 242 is used to reset the locking teeth 24 so that they can automatically reset after being disengaged from the surface of the toothed belt 16.

[0038] Specifically, L-shaped plates are fixed on both sides of the mounting shell 22. One end of the L-shaped plate is fixed to the top of the fixed shell 21. Protrusions are fixed on both sides of the bottom of the mounting shell 22. The L-shaped plates are used to connect the fixed shell 21 and the mounting shell 22, so that the fixed shell 21 and the mounting shell 22 can move synchronously around the pipeline, thereby adjusting the position of the fastening adjustment component 2 according to different pipeline sizes.

[0039] Specifically, the clamping component 26 includes a fixing block 261 fixed to the bottom of the inner cavity of the mounting housing 22, a second spring 262 fixed to the top of the fixing block 261, and a displacement plate 263 fixed to the top of the second spring 262.

[0040] Specifically, connecting slide rods 266 are fixed at the four corners of the bottom of the displacement plate 263, and toothed pressure plates 267 are fixed at the bottom of the connecting slide rods 266. The bottom of the toothed pressure plates 267 is flush with the bottom of the protrusion. The surface of the connecting slide rods 266 is slidably connected to the bottom of the mounting shell 22. The protrusion structure can hide the toothed pressure plates 267, so that they can be protected by the protrusion when they are not extended. The connecting slide rods 266 are used to guide the movement of the displacement plate 263, so that it can move stably along the sliding direction of the connecting slide rods 266.

[0041] Specifically, guide wheels 265 are fixed at the center of the inner cavity of the mounting shell 22, on one side of the inner cavity of the mounting shell 22, and on the surface of the fixing shell 21. A pull rope 264 is fixed at the bottom of the displacement plate 263. One end of the pull rope 264 passes through the guide wheel 265 and is fixed to the surface of the rotating wheel 231. A through hole is opened on the surface of the fixing block 261 for the pull rope 264 to pass through. By setting the guide wheel 265, the pull rope 264 can be guided so that it can move in a specified direction.

[0042] In use, wrap the side of the wrapping garment 11 facing the anti-slip sheet 110 around the pipe surface, fit the pre-drilled hole 13 onto the flange or valve surface, and fix it by bonding the second hook and loop fastener 17 to the second hook and loop fastener 18. Wrap the wrapping garment 11 around the pipe, and then stick the first hook and loop fastener 19 to the surface of the first hook and loop fastener 14 to pre-fix the wrapping garment 11 along the radial side of the pipe.

[0043] Then move the mounting shell 22 to the first Velcro side 19 and press the lanyard 15. Figure 1 Pass the compression belt 12 in the direction of the compression belt, and then press the toothed belt 16. Figure 3Insert the toothed belt 16 into the fixed shell 21 along the inclined surface of the tooth 24. Pull the toothed belt 16 so that it is engaged along the direction of the tooth 24. When the teeth on the toothed belt 16 pass the inclined surface of the tooth 24, the inclined surface will cause the tooth 24 to move away from the toothed belt 16 and compress the first spring 242, so that the toothed belt 16 can pass through the tooth 24 in the forward direction until the rope 15 is tightly tied to the surface of the pipe. The wrapping garment 11 is tied to the surface of the pipe by the rope 15. The position of the toothed belt 16 engaged in the tooth 24 can be adjusted according to the pipe size.

[0044] At this point, stop pulling the toothed belt 16. The retaining teeth 24 reset under the action of the first spring 242. Then, rotate the bolt 23. Under the action of the thread, drive the rotating wheel 231 to move towards the surface of the retaining teeth 24 until it is close to the retaining teeth 24, so that the retaining teeth 24 can no longer disengage from the toothed belt 16, thereby achieving a fixing effect. When the rotating wheel 231 rotates, it will wind up the pull rope 264. At this time, the pull rope 264 pulls the displacement plate 263 along the surface of the guide wheel 265, so that it drives the tooth pressure plate 267 to move towards the first Velcro surface 19 of the wrapping garment 11 through the connecting slide rod 266. The second spring 262 is compressed. When the bolt 23 rotates to the maximum state, the tooth pressure plate 267 just presses against the first Velcro surface 19 of the wrapping garment 11, so that the wrapping garment 11 is sealed at the pre-fixed position along the radial side of the pipe.

[0045] During disassembly, simply loosen bolt 23, then pull slide plate 241 from the outside to disengage tooth 24 from toothed belt 16. Then move toothed belt 16 out of the fixed housing 21 in the opposite direction. At this time, tether 15 is released, and pull rope 264 loses tension. Second spring 262 rebounds, causing displacement plate 263 and tooth pressure plate 267 to return to their original positions. Then separate first hook and loop fastener face 19 from first hook and loop fastener face 14, and second hook and loop fastener face 17 from second hook and loop fastener face 18. Then the device can be removed from the pipe.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
