Ring-shaped nozzle of heat gun

Abstract

The invention relates to a ring-shaped nozzle of a heat gun. The ring-shaped nozzle is connected to an outlet of a right cone type spray pipe of the heat gun and comprises a semi-ring-shaped nozzle I and a semi-ring-shaped nozzle II, wherein the center of the semi-ring-shaped nozzle I is connected with the right cone type spray pipe of the heat gun; and ring-shaped air outlets I are formed in the inner ring surfaces of the semi-ring-shaped nozzle I and the semi-ring-shaped nozzle II. The ring-shaped nozzle of the heat gun is reasonable in structural design and is formed by adding a front half ring part and a rear half ring part to a right cone type nozzle; a shrunk cable is nested into the ring-shaped nozzle, the heat gun sends out heat energy which enters ring-shaped space through a right cone type spray cylinder; a thin and uniform air outlet gap is formed in the inner wall of the ring-shaped space, heat is uniformly sprayed through the thin gap onto the outer wall of a heat shrinkable tube which is shrunk by heat, the heat shrinkable tube is uniformly heated, a large amount of heat energy is sufficiently used, and the heat shrinkage time of the cable is shortened greatly.

Description

technical field [0001] The invention relates to a heat gun nozzle, in particular to a heat gun ring nozzle used for heat shrinkable tubes. Background technique [0002] The nozzles of the hot air guns currently in use are straight cones, and the heat emitted is only a bunch. A large amount of heat can only be concentrated to one point and then dissipated. It takes about an hour to move the heat gun for the joint of the cable, which is time-consuming and labor-intensive. Due to the long time of heat-shrinking the cable, it will affect the operating rate of the oil well and affect the production. Contents of the invention [0003] The present invention aims at overcoming the deficiencies of the prior art, and provides a ring nozzle of a hot air gun, which successfully solves the above problems, especially in outdoor operations, and has a very good effect. [0004] The annular nozzle of the heat gun of the present invention is connected with the outlet of the straight tapere...

Problems solved by technology

[0002] The nozzles of the hot air guns currently used are straight cones, and the heat emitted is only a bunch. A large amount of heat can only be concentrated to one point and then dissipated. Only a small part of the heat is used, and most of the heat is wasted. It takes about an hour to move the heat gun to work on the root cable joint, which is time-consuming and labor-intensive. Due to the long time of heat-shrinking the cable, it will affect the operation rate of the oil well and affect the production
