Description
Technical Field
[0001] The utility model relates to the technical field of blowtorches, in particular to an insulating pull rod of a blowtorch. Background Art
[0002] The use of power lines brings great convenience to our domestic electricity use. Power lines are generally erected in the air. Light floating objects such as kites, cloth strips, plastic sheets, and wasp nests have always been potential hazards to the safe operation of power lines. Once wrapped around the power lines, it will cause faults such as leakage, arcing, and short circuits in the lines, resulting in large-scale power outages. Currently, the general method for removing high-altitude floating objects is to burn them with a blowtorch. In higher positions or positions that are inaccessible to humans, usually, an unmanned aerial vehicle is used to carry a blowtorch to clean the floating objects. For low positions within the city, an insulating pull rod is usually used to fix the blowtorch, and the floating objects are cleaned by manually holding it.
[0003] For most existing insulating pull rods of blowtorches, an empty tube is used inside. One end of the insulating pull rod is fixed to the blowtorch, and the connecting hose of the blowtorch is inserted from the inside of the insulating pull rod. However, the inserted connecting hose of the blowtorch is too loose or pulled inside the insulating pull rod, resulting in looseness at the connection with the blowtorch, reducing the safety performance during the use of the blowtorch. It is necessary to design an insulating pull rod for a blowtorch to solve the above-mentioned problems. Content of the Utility Model

[0006] An insulating pull rod of a blowtorch, comprising an insulating pull rod, a blowtorch fixing tube, and a handle tube. On the left and right sides of the insulating pull rod, a plurality of extension tubes are respectively fixedly connected at equal intervals. Empty slots are arranged inside the extension tubes, springs are arranged inside the empty slots. The outer ends of the extension tubes are all slidably connected to the outside of the connecting columns. The inner ends of the connecting columns are all fixedly connected with push clamping plates, and the outer ends of the connecting columns are all fixedly connected with fixing plates. The insulating pull rod is used to extend the blowtorch, the push clamping plate is used to fix the connecting hose of the blowtorch, the blowtorch fixing tube is used to fix the blowtorch, and the handle tube is used to hold the blowtorch by hand;
[0007] Through the above technical solution, one end of the connecting hose of the blowtorch is inserted into the inner side of the insulating pull rod. By pulling the pull ring, the whole formed by the push splint, the connecting column and the fixed disk slides outward on the inner side of the extension pipe, causing the spring to contract. When the connecting hose of the blowtorch passes through, the push splint is released, and it misaligns and clamps the connecting hose of the blowtorch with the inner wall of the insulating pull rod, making the connecting hose of the blowtorch and the insulating pull rod form an integral body, preventing the connecting hose from being too loose or pulled in the insulating pull rod during the use of the blowtorch, resulting in loosening at the connection with the blowtorch, and increasing the safety performance during the use of the blowtorch.
[0008] Further, the upper end of the insulating pull rod is fixedly connected to the bottom end of the first connecting sleeve by threads, and the upper end of the first connecting sleeve is threadedly connected to the bottom end of the blowtorch fixing pipe;
[0009] Through the above technical solution, it is convenient for the installation and disassembly between the blowtorch fixing pipe and the insulating pull rod, and at the same time increases the installation convenience of the blowtorch.
[0010] Further, the bottom end of the insulating pull rod is threadedly connected to the upper end of the second connecting sleeve, and the bottom end of the second connecting sleeve is threadedly connected to the upper end of the handle pipe;
[0011] Through the above technical solution, it is convenient for the installation and disassembly between the handle pipe and the insulating pull rod.
[0012] Further, fixed handles are fixedly connected to the upper parts of the left and right ends of the outer wall of the handle pipe, and anti-slip patterns are provided at the bottom of the outer wall of the handle pipe;
[0013] Through the above technical solution, by setting the fixed handles and the anti-slip patterns, the hand-held convenience is increased when holding the handle pipe, and at the same time the anti-slip performance is increased.
[0014] Further, pull rings are fixedly connected to the outer ends of the fixed disks;
[0015] Through the above technical solution, it is convenient to pull the whole formed by the push splint, the connecting column and the fixed disk to slide outward on the inner side of the extension pipe through the pull ring.
[0016] Further, the insulating pull rod, the blowtorch fixing pipe and the handle pipe are all made of insulating materials, and insulating coatings are sprayed on the inner and outer surfaces;
[0017] Through the above technical solution, the insulating performance of the insulating pull rod, the blowtorch fixing pipe and the handle pipe is increased, and at the same time the safety performance during use is increased.
[0018] The utility model has the following beneficial effects:
[0019] In the present utility model, first, the upper end of the handle tube is threadedly connected to the bottom end of the second connecting sleeve, and the upper end of the second connecting sleeve is threadedly connected to the bottom end of the insulating pull rod. Then, the bottom end of the blowtorch fixing tube is threadedly connected to the upper end of the first connecting sleeve, and the bottom end of the first connecting sleeve is threadedly connected to the upper end of the insulating pull rod. Secondly, one end of the blowtorch connecting hose is inserted into the bottom end of the handle tube and extends inward to the inside of the insulating pull rod. When the inserted end of the blowtorch connecting hose touches the push splint, the whole formed by the pull ring, the push splint, the connecting column and the fixed disk slides outward inside the extension tube, causing the spring to contract. When the blowtorch connecting hose passes through, the push splint is released, and it misaligns and clamps the blowtorch connecting hose with the inner wall of the insulating pull rod. Finally, the inserted end of the blowtorch connecting hose extends out from the upper end of the blowtorch fixing tube. After it is installed on the blowtorch, the blowtorch is installed and fixed through the blowtorch fixing tube, and the blowtorch connecting hose can be fixed inside the insulating pull rod, making the blowtorch connecting hose and the insulating pull rod form an integral whole, preventing the connecting hose from being too loose or pulled inside the insulating pull rod during the use of the blowtorch, resulting in looseness at the connection with the blowtorch, and increasing the safety performance during the use of the blowtorch.
