Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Embodiment 1:

[0025] This embodiment is used to solve the problem that the existing thermal insulation structure is difficult to disassemble quickly during the later maintenance process, and it is difficult to fully protect the thermal insulation layer.

[0026] See also Figure 1 - Figure 5 As shown, this embodiment is a heat preservation structure suitable for a small heat control pipe, including a heat preservation cotton 1 sleeved on the small pipe, a sleeve 2 sleeved on the outer contour of the heat preservation cotton 1, and the sleeve 2 is formed by bending a stainless steel skin. The stainless steel skin has high tensile strength and yield strength. The stainless steel skin can resist corrosion from a variety of chemical substances and can fully protect the outer side of the small heat control pipe. The sleeve 2 and the heat preservation cotton 1 are selected according to the size of the small heat control pipe, which can fully improve its flexibility.

[0027] A quick-release structure is sleeved on the outer contour of the sleeve 2, and the quick-release structure includes two symmetrically arranged connecting frames 3 located on the outer contour of the sleeve 2. The two connecting frames 3 are arranged in a rectangular shape as a whole. One end of the two connecting frames 3 is hinged to each other, and the other ends of the two connecting frames 3 are engaged with each other. When the other ends of the connecting frames 3 are released from the engagement, the two connecting frames 3 can be unfolded and separated, which has the advantage of being easy to quickly disassemble the connecting frames 3. Compared with the existing bolt and clamp fixation, it can be quickly disassembled without tools, which is convenient for regular replacement and maintenance of the sleeve 2;

[0028] The two connecting frames 3 are penetrated by and horizontally slidably connected with a limit rod 6, and the opposite ends of the two limit rods 6 are fixedly connected with a positioning piece 5. When the two limit rods 6 are close to each other, the positioning piece 5 can be abutted against the outer contour of the sleeve 2. A spring 7 is sleeved on the outer contour of the limit rod 6, one end of the spring 7 abuts against the connecting frame 3, and the other end of the spring 7 abuts against the positioning piece 5. Under the action of the spring 7, the positioning piece 5 can always abut against the outer wall of the sleeve 2, so as to position the outer wall of the sleeve 2 and prevent the sleeve 2 from easily separating and falling from the thermal insulation cotton 1. A connecting sleeve 4 is sleeved at the connection between two adjacent sleeves 2, and the connecting sleeve 4 seals the connection to prevent the connection from being exposed to the outside and affecting the thermal insulation effect of the small thermal control pipeline.

[0029] The positioning piece 5 is an arc-shaped setting that fits the outer contour of the sleeve 2, and can better fit the outer contour of the sleeve 2. The end of the limiting rod 6 away from the positioning piece 5 is fixedly connected with a blocking piece 10 to prevent it from being easily separated from the connecting frame 3 under the action of the spring 7.

[0030] One end of the connecting frame 3 that is engaged with each other is provided with an insertion groove 8, and an insertion block 9 is inserted into the two insertion grooves 8. The insertion block 9 is inserted into the insertion grooves 8 opened by the two connecting frames 3. In conjunction with the spring 7, the end of the connecting frame 3 close to the insertion groove 8 can generate a pulling force on the insertion block 9, so that it can be stably engaged and prevent easy separation.

[0031] The connecting sleeve 4 is composed of two mutually hinged semicircles. An extension portion 13 is provided at one end of the connecting sleeve 4 away from the hinge. A through slot for plugging is provided on the extension portion 13. The extension portion 13 can be fixed in cooperation with a plug-in rod.

[0032] The inner wall of the connecting sleeve 4 is fixedly connected to a sealing ring 2 12 near both ends, and the outer contour of the adjacent sleeve 2 end is fixedly connected to a sealing ring 11 adapted to the sealing ring 2 12, and the sealing ring 2 12 is located on the outside of the sealing ring 11. By arranging the sealing ring 11 and the sealing ring 2 12 to cooperate, the two sealing rings 11 are located between the two sealing rings 2 12, which can prevent the spring 7 from moving in the axial direction of the sleeve 2, so that it can be stably located at the connection between the two sleeves 2.

[0033] Embodiment 2:

[0034] This embodiment is used to solve the problem of fully protecting the thermal insulation layer.

[0035] See also Figure 1 , Figure 5As shown, an insulation structure suitable for a small thermal control pipe in this embodiment includes two symmetrically arranged semicircular blocks 14 at intervals in a sleeve 2, the two semicircular blocks 14 are engaged with each other, and two connecting sleeves 4 are arranged on the outer contour of the thermal insulation cotton 1 at intervals. The overlapping positions of the two semicircular blocks 14 engaged with each other are penetrated and plugged with a connecting column 16, and the connecting column 16 is screwed to one of the semicircular blocks 14. When the connecting column 16 is rotated, the semicircular block 14 can move the connecting column 16 toward the small thermal control pipe. One end of the connecting column 16 away from the small pipe is fixedly connected with a support sheet 15 that abuts against the inner wall of the sleeve 2. The support sheet 15 is a ductile stainless steel skin. The support sheet 15 fits with the inner wall of the sleeve 2 and can cooperate to support the inner wall of the sleeve 2, and cooperate with the positioning sheet 5 to clamp the outer wall of the sleeve 2, which can prevent the sleeve 2 from deforming easily.

[0036] Combining Embodiment 1 and Embodiment 2

[0037] By setting up a quick-release structure, it can be quickly disassembled without using tools, which greatly facilitates the regular replacement and maintenance of the sleeve 2, reduces maintenance costs, and improves work efficiency. The sleeve 2 is made of bent stainless steel and has high tensile strength and yield strength, and can resist corrosion from a variety of chemical substances, thereby providing sufficient protection for the outside of the small thermal control pipeline and effectively extending the service life of the pipeline. The positioning piece 5 is always in contact with the outer wall of the sleeve 2, effectively preventing the sleeve 2 from easily separating and falling from the insulation cotton 1, ensuring the stability and safety of the insulation structure. The support piece 15 fits with the inner wall of the sleeve 2 and can cooperate to support the inner wall of the sleeve 2. It cooperates with the positioning piece 5 to clamp the outer wall of the sleeve 2, which can prevent the sleeve 2 from being easily deformed.

The connecting sleeve 4 closes the connection between the two sleeves 2 to prevent the connection from being exposed to the outside and affecting the thermal insulation effect of the small thermal control pipe.
