Abstract
Claims
1. A freeze protection jacket for a water service pipe, characterized by: The device includes an insulated hose (1), which has a heating wire (6) inside. A control box (5) is matched with the heating wire (6). The control box (5) is connected to a temperature sensor (4) via a wire. The temperature sensor (4) is located inside the insulated hose (1). Multiple fixing straps (2) are fitted on the outside of the insulated hose (1). One end of each fixing strap (2) is fixedly connected to a fixing component (3).
2. A freeze-proofing jacket for a water pipe according to claim 1, characterized in that: The temperature sensor (4) and the heating wire (6) are both electrically connected to the control box (5).
3. A freeze-proofing jacket for a water pipe according to claim 1, characterized in that: The side of the thermal insulation hose (1) is designed to be open.
4. A freeze-proofing jacket for a water pipe according to claim 1, characterized in that: The fixing component (3) includes a loop block (31) fixedly connected to one end of the fixing band (2). The side wall of the loop block (31) is penetrated and connected to a screw (32) by a thread. One end of the screw (32) located inside the loop block (31) is connected to a pressure plate (33) by a bearing. The other end of the screw (32) is fixed with a knob (34).
5. A freeze-proofing jacket for a water pipe according to claim 4, wherein: A rubber pad is provided on the surface of the pressure plate (33) at the end away from the screw (32).
6. A freeze-proofing jacket for a water pipe according to claim 1, characterized in that: The fixing component (3) includes a herringbone block (31) fixedly connected to one end of the fixing band (2). The herringbone block (31) has a groove (35) on its inner sidewall. A spring (36) is fixedly connected to the inner sidewall of the groove (35). A slide plate (37) is fixedly connected to the other end of the spring (36). An inclined tooth (38) is fixedly connected to the side of the slide plate (37) away from the spring (36). The other end of the fixing band (2) passes through the inside of the herringbone block (31). Several inclined protrusions (21) are fixed to the side of the fixing band (2) near the inclined tooth (38). The inclined tooth (38) engages between two adjacent inclined protrusions (21).
7. A freeze-proofing jacket for a water pipe according to claim 6, wherein: A through hole (39) is provided on the side of the groove (35) away from the slide plate (37). A pull rod (310) is slidably connected through the through hole (39). The pull rod (310) is fixedly connected to the slide plate (37). An end plate (311) is fixedly connected to one end of the pull rod (310) outside the loop block (31).
