[0003] However, the application does not take into account that in actual use, because pipelines are often used in different environments, the length of the pipelines often changes. At this time, if the heating tape cannot be adjusted to suit the length of the pipeline, it is easy to cause trouble and the heating effect cannot be achieved well. Therefore, how to adjust the length of the heating tape has become a direction of effort. Utility Model Content
[0004] The purpose of the present application is to provide a boiling water circulating self-limiting temperature heating belt in order to solve the above-mentioned problem of adjusting the length of the heating belt.
[0005] The technical solution adopted in the present application is as follows: a boiling water circulating self-limiting temperature heating belt, the side surface of the upper hollow connecting round rod is fixedly connected with a series connecting head, the side surface of the series connecting head is fixedly connected with a plurality of cross bar placement vertical plates, the side surface of the cross bar placement vertical plates is provided with a plug-in rod sliding groove, the side surface of the plug-in rod sliding groove is slidably inserted with a pull-out cross bar through the opened hole groove, the side surface of the pull-out cross bar is inserted with a series plug-in rod, the series plug-in rod is rotatably inserted with a fastening bolt relative to one end of the pull-out cross bar, the upper hollow connecting round rod is fixedly connected with a series insertion head relative to one end of the series connecting head, the side surface of the series insertion head is provided with a plurality of fixed circular holes, and the upper surface of the series connecting head is provided with a connector fixing circular hole.
[0006] By adopting the above technical solution, the operator uses the upper hollow connecting rod to place the serial connector and the serial insertion head at a horizontal height, which is convenient for docking and ensures that the structure used for connection is connected to the main structure of the heating belt. The horizontal rod is used to place the vertical plate and the plug-in rod sliding groove to fix the twitching horizontal rod on the track, and the serial plug-in rod is used as the main plug-in rod structure. When the serial connector and the serial insertion head are connected to each other, the fixed circular hole of the connector and the fixed circular hole are overlapped, and then the serial plug-in rod is inserted into the series to achieve connection, and it is tightened with a fastening bolt to achieve fixation. Among them, the upper hollow connecting rod is used as the main connection structure, which not only connects the structures used for connection to each other, but also guides the water flow due to its hollow nature. The serial connector and the serial insertion head are the main connecting parts. Due to their connection function, multiple single heating belts can be connected in series. Different numbers of single heating belts can be connected in series according to actual conditions to adjust the size of the overall heating belt device, so as to better adapt to the needs of pipelines of different lengths.
[0007] The three structures of the horizontal bar mounting vertical plate, the plug rod sliding groove, and the pulling horizontal bar provide the ability to pull up and down, which not only effectively solves the source of pulling flexibility, but also connects the serial plug rod to the device to avoid the problem of loss caused by single use. The serial plug rod and the fixed circular hole and the connector fixed circular hole are connected in series to achieve the connection and binding of the serial connector and the serial insertion head. The structure is simple and easy to maintain, and the connection effect is good. The tightening bolts are used to fix the connection to prevent the shaking and loosening of the serial plug rod from causing the device structure to be unstable. Through the above structure, the operator can make adjustments according to the actual length of the pipeline, so that the heating belt can better fit the pipeline and provide better functions. The structure is integrated, simple and easy to operate, efficient and labor-saving.
[0008] In a preferred embodiment, the side surface of the upper hollow connecting round rod is fixedly inserted with the pipeline upper heating plate, the side surface of the pipeline upper heating plate is fixedly connected with the heat transfer plate, the side surface of the heat transfer plate is connected with a fixing screw, the fixing screw is connected with a hinge connecting piece via a threaded hole opened on the side surface of the heat transfer plate, and the side surface of the fixing screw is rotatably hinged with a rotatable hinge shaft.
[0009] By adopting the above technical solution, the operator uses the closed characteristics of the upper hollow connecting rod at both ends to guide the boiling water to the upper heating plate of the pipeline and contain the boiling water to provide heating. The upper heating plate of the pipeline is supported by the heat transfer plate, which not only utilizes the heat transfer plate to achieve heat transfer, but also avoids direct contact between the upper heating plate of the pipeline and the pipeline, causing collision damage and leakage. The hinge structure formed by the rotatable hinge shaft and the hinge connecting piece is used to connect the upper and lower single heating belts. By rotating the hinge, compared with a single heating belt, the larger the area that fits the pipeline, the more efficient the heating is.

[0011] By adopting the above technical scheme, boiling water is introduced into the upper hollow connecting round rod by using a boiling water inlet pipe, wherein the boiling water for providing heating is introduced by using a boiling water supply multi-head, and then the boiling water is introduced into the boiling water inlet pipe by using a retractable boiling water supply pipe. Because of the retractable performance of the retractable boiling water supply pipe, the distribution of the heating belt can be adjusted according to the diameter of the pipeline, making the use more flexible and convenient.

At the same time, the connection between the boiling water supply plug-in pipe and the boiling water supply connector is fixed by fixing bolts to prevent the connection from loosening and boiling water overflowing to cause safety risks. The flow control plug plate can be operated downward to adjust the supply flow of boiling water, so as to control the heating supply efficiency at different stages.
[0014] In a preferred embodiment, a support column is fixedly connected to the lower surface of the boiling water supply multi-head, and a pipe-fitting plastic support plate is fixedly connected to one end of the support column opposite to the boiling water supply multi-head.
[0015] By adopting the above technical solution, the operator uses the pipe-fitting plastic support plate to fit the pipe, and then uses the supporting columns to support the entire structure on the pipe.

After the lower heating plate and the lower hollow connecting round rod of the pipeline receive the boiling water in the upper part, they continue to provide heat in the lower part, realizing the multi-directional heating of the pipeline and ensuring the efficiency of heating. The cooling water outlet pipe discharges the cooling water after providing heat.
[0018] In a preferred embodiment, a plug-in connection block is inserted into one end of the cooling water outlet pipe relative to the lower hollow connecting round rod, a cooling water recovery pipe is inserted into the plug-in connection block relative to one end of the cooling water outlet pipe, and an anti-slip fastening bolt is provided on the side surface of the plug-in connection block.
[0019] By adopting the above technical solution, after the cooling water outlet pipe is plugged into the plug-in connection block, the plug-in position is fixed by anti-dropping fastening bolts to prevent loosening, and the discharged cooling water is recovered through the cooling water recovery pipe.
[0020] In a preferred embodiment, a recovery pipe connector is fixedly connected to the side surface of the cooling water recovery pipe, and an auxiliary connecting plastic rod is fixedly connected to the side surface of the recovery pipe connector. A plug-in circular hole is provided on one end of the auxiliary connecting plastic rod relative to the cooling water recovery pipe, and a plurality of plug-in protrusions are provided on the side surface of one end of the cooling water recovery pipe relative to the recovery pipe connector.
