Description

Technical Field

[0001] The utility model relates to the technical field of water heater component production equipment, in particular to a heat shrinkable tube sleeve device. Background Art

[0002] The water inlet pipe at the end of the heating tube is usually a heat shrink tube. When the heat shrink tube is installed and fixed, the operator first installs the heat shrink tube on the heating tube, and then heats the heat shrink tube with a hot air blower. After heating, the heat shrink tube shrinks due to the heat. There are two main problems in the operation. First, the heat shrink tube is in a flat structure when installed, which affects the installation operation, and the use of a hot air blower for heat shrinkage is easy to cause burns to the operator's hands. Utility Model Content

[0003] The utility model provides a heat shrink tube sleeve device to solve the deficiencies of the above-mentioned prior art. The end of the heat shrink tube can be propped open, thereby facilitating the insertion of the heating tube into the heat shrink tube and facilitating the heating operation of the heat shrink tube, and has strong practicality.

The outward-pushing cylinder is provided to facilitate the insertion of the expansion plate into the end of the heat shrink tube, and then the expansion plate is driven to move outward by the opening cylinder to open the heat shrink tube. As the heat shrink tube opens, it is convenient for the operator to insert the heating tube into the heat shrink tube. When the heating tube is inserted, the expansion plate is pushed out by the outward-pushing cylinder, and then a hot air flow is sprayed onto the heat shrink tube through the air inlet nozzle to perform heat shrinkage.

[0006] Furthermore, the support plate has an arc-shaped structure to facilitate the sleeve transfer operation of the heating tube.

[0007] Furthermore, the outer wall of the inner end of the expansion plate is formed with a conical surface, and the outer end of the conical surface is a small end to facilitate the insertion operation of the expansion plate.
