DETAILED DESCRIPTION

[0022] The following is a detailed description of a HVAC pipe antifreeze and heat preservation mechanism of the utility model with reference to the accompanying drawings of the specification.

[0023] Embodiment 1

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, the utility model proposes a HVAC pipe antifreeze insulation mechanism, which structure includes an insulation mechanism 200 and a tensioning mechanism 300, the insulation mechanism is sleeved with the pipe, the insulation mechanism 200 includes a flange 201 fixedly connected to the end face of the pipe 100 and an insulation sleeve 202, two flanges 201 are provided, and an insulation sleeve 202 is sleeved and fixed between the two flanges 201, and the insulation sleeve 202 is sleeved with the pipe. At least one tensioning mechanism 300 is provided on the outside of the insulation mechanism 200, and the tensioning mechanism 300 includes a wedge plate 301, a screw sleeve 306 and a screw 305 that are snap-connected to the outside of the insulation sleeve 202, the screw sleeve 306 is provided on the top of the wedge plate 301, the screw 305 is threadedly connected to the screw sleeve 306, and one end of the screw provided in the screw sleeve abuts against the top wall of the wedge plate. The threaded connection between the screw sleeve 306 and the screw rod 305 facilitates lifting and lowering adjustment, improves the fit between the thermal insulation structure 200 and the pipeline 100, and the pipeline 100 is not easily damaged or broken.

[0025] The cooperation between the insulation mechanism 200 and the pipeline 100 allows the insulation performance of the pipeline 100 to be directly supported for a long time, thereby reducing the cracking and damage of the pipeline 100 caused by temperature difference. The flange 201 is connected with the insulation sleeve 202, so that the insulation sleeve 202 can provide insulation effect for the pipeline 100 at a predetermined position. The determination of the physical position of the insulation sleeve 200 can significantly improve the undesirable phenomenon of overheating and overcooling in certain areas of the pipeline 100; the cooperation between the rotating wheel 307, the screw 305 and the wedge plate 301 allows the screw 305 to rotate automatically after the expansion of the pipeline 100 is found, thereby avoiding secondary damage to the pipeline 100.

[0026] The tensioning mechanism 300 also includes a square frame 302, a limiting rod 304, an adjusting column 313, a straight spring 312 and a fixing seat 311. The two ends of the bottom of the square frame 302 are respectively plugged with the wedge plate 301. The top of the wedge plate 301 is provided with a through slot 303, which is convenient for the whole device to be hoisted and hooked. The inner side of the square frame 302 is respectively provided with a limiting rod 304. One end of the adjusting column 313 is connected to the limiting rod 304, and the other end of the adjusting column 313 is connected to one end of the straight spring 312. The other end of the straight spring 312 is connected to one end of the fixing seat 311, and the other end of the fixing seat 311 is connected to the side wall of the screw sleeve 306. The side wall of the limiting rod 304 is evenly provided with a plurality of adjusting slots from top to bottom, and one end of the adjusting column is movably plugged with the adjusting slot.

[0027] The fixed connection between the square frame 302 and the limiting rod 304 limits the movement of the adjusting column 313, thereby ensuring the stable adjustment of the tensioning mechanism 300. The fixing of the straight spring 312 and the fixing seat 311 can absorb other forces except the axial force, further ensuring the consistency and stability of the adjustment effect.

[0028] When in use, firstly, the two flanges 201 are sleeved on the two ends of the pipe 100, then the insulation sleeve 202 is fixedly connected to the two flanges 201, and then the wedge plate 301 is clamped to the side of the insulation sleeve 202, the screw 305 is rotatably connected to the top of the wedge plate 301, and the rotating wheel 307 is fixed on the top of the screw 305, the square frame 302 is plugged into the wedge plate 301, and at the same time, the limit rod 304 is fixedly connected to the inner side of the square frame 302, so that the adjustment column 313 and the limit rod 304 are movably plugged, and the straight spring 312 is fixedly connected to the fixing seat 311 for stable tension adjustment.

[0029] In summary, through the cooperation between the insulation mechanism 200 and the pipeline 100, the insulation performance of the pipeline 100 can be directly supported for a long time, thereby reducing the cracking and damage of the pipeline 100 caused by temperature difference. The flange 201 is connected with the insulation sleeve 202, so that the insulation sleeve 202 can provide insulation effect for the pipeline 100 at a predetermined position. The determination of the physical position of the insulation sleeve 200 can significantly improve the undesirable phenomenon of overheating and overcooling in certain areas of the pipeline 100; through the fixed connection between the square frame 302 and the limiting rod 304, the movement of the adjusting column 313 is subject to the limiting effect, thereby ensuring the adjustment stability of the tensioning mechanism 300.

[0030] Embodiment 2

[0031] Reference Figure 2-3 , which is the second embodiment of the utility model. Different from the previous embodiment, this embodiment provides relevant parts for achieving a stable tensioning adjustment effect.

[0032] Specifically, the other end of the fixed seat 311 is connected to the side wall of the screw sleeve 306 through a connecting piece 310. The connecting piece 310 includes a first connecting rod 310a connected to the fixed seat 311, a support shaft 310b, a second connecting rod 310c and a side rod 308 connected to the side wall of the screw sleeve, the first connecting rod and one end of the second connecting rod are hinged through the support shaft, and the other end of the second connecting rod is hinged to one end of the side rod through a hinge column. The side rod 308, the hinge column 309 and the second connecting rod 310c are arranged in coordination, so that the shaking of the screw sleeve 306 during lifting and lowering can be directly transmitted.

[0033] The first connecting rod 310a and the second connecting rod 310c are both integrally formed steel rods, and an angle is set between the first connecting rod 310a and the second connecting rod 310c. The angle between the first connecting rod 310a and the second connecting rod 3120c can ensure high efficiency of rotational movement. When in use, the second connecting rod 310c, the support shaft 310b and the first connecting rod 310a are assembled and connected in sequence, and then the first connecting rod 310a and the second connecting rod 310c are formed into an angle.

[0034] When the rotating wheel 307 and the screw 305 rotate, the screw 305 can be lifted and displaced, and the lifting and lowering of the screw 305 can pull the side rod 308 to rotate. The rotation of the side rod 308 can transmit torque in sequence through the hinge column 309, the second connecting rod 310c, the support shaft 310b, and the first connecting rod 310a, and finally transmit it to the straight spring 312, and cause the straight spring 312 to stretch; the straight spring 312 can absorb the jitter of the screw 305 when it is lifted and lowered, thereby improving the rotation stability of the screw 305, and indirectly making the insulation sleeve 202 and the pipeline 100 fit more closely.

[0035] When in use, the second connecting rod 310 c , the hinge column 309 and the side rod 308 are rotated and installed in sequence, and then the side rod 308 is fixedly connected to the screw sleeve 306 , and the screw sleeve 306 is threadedly connected to the screw rod 305 .

[0036] The above description is only used to illustrate some principles of the utility model. This specification is not intended to limit the utility model to the specific structure and application scope shown and described. Therefore, all corresponding modifications and equivalents that may be used belong to the patent scope applied for the utility model.
