Technical Field
[0001] This utility model belongs to the field of electric heat tracing technology, and in particular to a self-fixing electric heat tracing tape. Background Technology
[0002] Self-fixing electric heating cables are a type of electric heat tracing product with a unique structure and function. They contain a heating core, typically made of alloy materials. This heating core generates heat when electricity is applied, providing a heat source for equipment or pipelines requiring heat tracing. Existing self-fixing electric heating cables can meet basic heating needs. However, after a period of use, the self-fixing electric heating cable may become loosely attached to the pipeline, hindering heat transfer, accelerating cable aging, and causing uneven heating.
[0003] A search revealed a Chinese patent document (authorization announcement number CN211128257U), which discloses a self-fixing electric heating cable, comprising an electric heating cable body, an upper fixing device, a lower reinforcing device, and screws. The electric heating cable body is provided with the upper fixing device and the lower reinforcing device, which are fixedly connected by screws. The upper fixing device includes a fixing plate, with upper clamping plates fixedly installed on both sides of the fixing plate. A fixing seat is fixedly installed on the side of each of the two upper clamping plates away from the fixing plate. A magnet is fixedly installed on the top of the fixing plate. This invention allows the electric heating cable to be attached to the equipment pipeline by a magnet on a fixing plate, thus completing the installation. The installation steps are simple and efficient, and no other auxiliary tools are required. The cooperation between screws and installation sleeves ensures the structural stability of the fixing plate and reinforcement plate on the electric heating cable, guaranteeing the stability of the electric heating cable after installation. This self-fixing electric heating cable can meet basic heating needs. However, after a period of use, the self-fixing electric heating cable may not adhere firmly to the pipeline, hindering heat transfer, accelerating the aging of the electric heating cable, and causing uneven heating. Utility Model Content
[0004] The purpose of this invention is to provide a self-fixing electric heating cable to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a self-fixing electric heating tape, comprising a fixing plate for locking the electric heating tape, a fixing tape storage box installed on the side of the fixing plate, a fixing post for self-fixation installed inside the fixing tape storage box, a helical spring connected to the outer periphery of the fixing post, a flexible fixing tape connected to the end of the helical spring away from the fixing post, a locking block installed at the end of the flexible fixing tape away from the helical spring, a locking hole provided on the surface of the flexible fixing tape, a locking box installed at the bottom of the fixing tape storage box, a latch provided inside the locking box, and a button provided on the side of the locking box.
[0006] Preferably, a connecting plate is connected to the side of the button, and a push plate is installed on the end of the connecting plate away from the button.
[0007] Preferably, a baffle is installed on the surface of the fixed storage box, and a slider is slidably connected inside the baffle.
[0008] Preferably, a locking post is installed on the side of the slider, a support post is connected to the side of the slider, and a pressure plate is installed on the end of the support post away from the slider.
[0009] Preferably, a hollow column is installed on the side of the fixing plate, and a spring is provided inside the hollow column.
[0010] Preferably, the end of the spring away from the fixed plate is connected to a connecting post, and the end of the connecting post away from the hollow post is fitted with a clamping plate.
[0011] Preferably, a movable column is installed on the side of the clamping plate, and a handle is connected to the end of the movable column away from the clamping plate. An electric heating cable fixing position is provided between the clamping plates.
[0012] Compared with the prior art, the technical effects and advantages of this utility model are:
[0013] This self-fixing electric heating cable benefits from the structure of a spiral spring and a locking box. Pulling the flexible fixing band secures the electric heating cable to the pipe. Inserting the locking block into the locking box engages with the latch, which then secures the locking block. The spiral spring tightens the flexible fixing band, ensuring full contact and fixation between the electric heating cable and the pipe. Pressing the button pushes a push plate towards the locking block via a connecting plate, separating the locking block from the latch and allowing the electric heating cable to be removed. This structure ensures a more secure fit between the self-fixing electric heating cable and the pipe, increases heat transfer, reduces the aging of the electric heating cable, and provides uniform heating.
[0014] This self-fixing electric heating cable benefits from the clamp structure. When the electric heating cable is placed in the fixing position and the handle is released, the spring pulls the connecting column, which in turn drives the clamp to fix the electric heating cable. This structure can quickly fix the electric heating cable and makes the cable fixing more secure. Attached Figure Description
