Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0053] Please see Figure 1-5 This utility model provides a technical solution: a thermal insulation elbow installation and fixing structure, comprising:

[0054] Insulated elbow 1, with annular connectors 2 fixedly sleeved at both ends and the middle of its outer wall;

[0055] The lower end of the annular connector 2 is fixedly fitted with a support base 4;

[0056] The annular connector 2 includes:

[0057] The upper ring 21 and the lower ring 22 are fitted with a snap-fit ​​connection structure 24 between their outer surfaces on the same side.

[0058] Elastic support mechanisms 23 are fitted on the front and rear sides of the outer walls of the upper ring 21 and the lower ring 22;

[0059] The inner ends of the front and rear corresponding elastic support mechanisms 23 are fixedly fitted with elastic pads 26.

[0060] The elastic gasket 26 is attached to the same side of the outer wall of the insulation elbow 1.

[0061] Specifically, in this embodiment, the insulation layer of the insulated elbow 1 is polyurethane foam;

[0062] Furthermore, the outer walls of the insulation elbow 1 are fixedly fitted with annular connectors 2 at both ends and the middle. The lower end of the annular connector 2 is fixed with a support base 4, which is fixed to the wall or platform. This increases the contact area between the fixing component 2 and the outer wall of the insulation elbow 1, better disperses the pressure, and reduces the probability of damage to the insulation layer of the outer wall of the insulation elbow 1.

[0063] More specifically, the outer walls of the upper ring 21 and lower ring 22 of the annular connector 2 are provided with an elastic support mechanism 23. The elastic pad 26 at the inner end of the elastic support mechanism 23 abuts against and fits against the outer wall of the insulation elbow 1 for positioning. The elastic pad 26 is elastic, which reduces the probability of damage to the insulation layer of the outer wall of the fitted insulation elbow 1.

[0064] Understandably, the elastic support mechanism 23 has suitable strength, which allows the elastic pad 26 to be pressed against and adhered to the outer wall of the insulation elbow 1 while preventing it from loosening due to insufficient fastening force.

[0065] In some embodiments, the snap-fit ​​connection structure 24 includes:

[0066] The upper connecting plate 242 is fixedly connected to the lower edge of the outer side of the upper ring 21;

[0067] The lower connecting plate 241 is fixedly connected to the outer edge of the lower ring body 22.

[0068] The upper connecting plate 242 and the lower connecting plate 241 have corresponding through holes 243 on their upper and lower surfaces;

[0069] The connecting post 244 is inserted into the through hole 243 of the upper connecting plate 242 and the lower connecting plate 241;

[0070] A round cap 248 is fixedly fitted to the upper end of the connecting post 244, and its lower end abuts against the upper edge of the through hole 243.

[0071] A conical block 245 is fixedly assembled at the lower end of the connecting column 244, and an elastic metal plate 246 is integrally formed on the left and right edges of its upper surface.

[0072] A locking block 247 is fixedly mounted on the upper part of the outer side of the elastic metal plate 246, and the upper ends of the locking blocks 247 on both sides abut against the lower edge of the through hole 243.

[0073] Specifically in this embodiment, the through holes 243 on the upper connecting plate 242 and the lower connecting plate 241 overlap and connect. The gripping round cap 248 makes the conical block 245 at the lower end of the connecting post 244 pass through the through holes 243 on the upper connecting plate 242 and the lower connecting plate 241. During the process of passing through the through holes, the locking blocks 247 at the upper end of the outer wall of the elastic metal plates 246 on both sides fit against the inner wall of the through holes, and the elastic metal plates 246 are squeezed and deformed. When the locking blocks 247 on both sides pass through the through holes and are no longer squeezed, the elastic metal plates 246 drive the locking blocks 247 to reset. After the reset locking blocks 247, the upper end of the locking blocks 247 abuts against the lower edge of the through holes 243 to achieve the locking effect.

[0074] Furthermore, it is necessary to disassemble and deform the elastic metal plates 246 on both sides, so that the locking blocks 247 on both sides move inward. Keep the locking blocks 247 on both sides in a state of compression, then grasp the round cap 248 and pull the connecting column 244 upward, so that the locking blocks 247 on both sides move upward into the through hole, and finally pull them out from the through hole.

[0075] In some embodiments, the outer wall of the round cap 248 is provided with anti-slip texture. The anti-slip texture increases the friction of the outer wall of the round cap 248, making it easier to grip the round cap 248 and drive the connecting column 244 fixed on the bottom surface for installation and disassembly.

[0076] In some embodiments, the resilient pad 26 includes:

[0077] The elastic rubber pad 261 has a strip-shaped mounting cavity 262 formed on its inner wall along the length direction;

[0078] A flexible metal mesh 263 is pasted and fixed inside the strip-shaped mounting cavity 262.

[0079] Specifically, in this embodiment, the flexible metal mesh 263 is a metal mesh woven from flexible steel wires. The flexible metal mesh 263 is disposed inside the elastic rubber pad 261 to improve the support capacity of the elastic pad 26.

[0080] Furthermore, the elastic rubber pad 261 adheres to the outer wall of the insulation elbow 1 through its elastic material, reducing the probability of damage to the insulation layer of the insulation elbow 1.

[0081] In some embodiments, two strip-shaped mounting cavities 262 are opened inside and outside, and the number of flexible metal mesh 263 is increased to further improve the support capacity of the elastic pad 26.

[0082] In some embodiments, an arc-shaped connecting rod 3 is fixedly mounted on the outer wall of the adjacent annular connector 2. The arc-shaped connecting rod 3 shields the outside of the insulation elbow 1, reducing the probability of the insulation elbow 1 being directly impacted. After being impacted, the pressure is distributed and transmitted to the support base 4.

[0083] In some embodiments, there are two arc-shaped connecting rods 3;

[0084] Two arc-shaped connecting rods 3 are located on the inner and outer sides of adjacent annular connectors 2, respectively. Increasing the number of arc-shaped connecting rods 3 provides better protection and force transmission and dispersion.

[0085] In some embodiments, a U-shaped frame 25 with left and right openings is fixedly mounted on the bottom surface of the lower connecting plate 241.

[0086] The connecting post 244 is located inside the U-shaped frame 25, and the U-shaped frame 25 provides shielding and protection for the lower end of the snap-fit ​​connection structure 24;

[0087] Furthermore, fingers are inserted from both sides of the U-shaped frame 25 to squeeze and deform the elastic metal plates 246 on both sides.

[0088] In some embodiments, the resilient support mechanism 23 includes:

[0089] Through hole 233 is formed on the outer wall of upper ring 21 and lower ring 22;

[0090] A round rod 232 is inserted into the through hole 233;

[0091] A pressure block 231 is fixedly assembled on the inner end of the round rod 232, which is fixed to the outer wall of the elastic pad 26 on the same side.

[0092] A spring 234 is sleeved on the lower end of the outer wall of the round rod 232, and its two ends abut against the inner ring surface of the upper ring body 21, the lower ring body 22 and the outer side of the corresponding pressure block 231, respectively.

[0093] Specifically in this embodiment, the spring 234 acts as an elastic element to support the elastic pad 26 on the same side against the outer wall of the insulation elbow 1. The spring 234 has sufficient strength to keep the elastic pad 26 against and attached to the outer wall of the insulation elbow 1 while preventing it from loosening due to insufficient fastening force.

[0094] Furthermore, the round rod 232 slides within the corresponding through hole 233, guiding the extension and retraction direction of the spring 234;

[0095] More specifically, the inner surface area of ​​the pressure block 231 is relatively large, which can better press the elastic pad 26 against the outer wall of the insulation elbow 1.

[0096] In some embodiments, the support base 4 includes:

[0097] There are two support rods 41 distributed at the front and back, and the two support rods 41 are symmetrically fixed and assembled on the front and back sides of the bottom of the annular connector 2.

[0098] The bottom of the front and rear support rods 41 is fixedly fitted with a base plate 42, and fixing bolts 43 pass through the four corners of the base plate.

[0099] Specifically in this embodiment, a gap is left between the front and rear support rods 41 to accommodate the lower snap-fit ​​connection structure 24;

[0100] Furthermore, the base plate 42 is fixed to the wall or platform by fixing bolts 43, which can be replaced by expansion bolts.

[0101] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
