[0017] When igniting the quenching furnace body 10, there is no need to use your hands, and the staff can keep a distance from the furnace opening of the quenching furnace body 10, which will not cause harm to the staff and greatly improves the safety of ignition. At the same time, the long plate 70 is also equipped with an air inlet, which can hold a blower and enhance the firepower.

[0018] Specifically, the swing mechanism 90 includes a gear 91 rotatably connected to the other side of the long plate 70. The gear 91 is fixedly connected to the igniter 80. A sliding rack 92 is provided on the front side of the gear 91 and meshes with it. A connecting block 93 is provided on the front side of the sliding rack 92 and slides up and down with it. The connecting block 93 is welded to the other side of the long plate 70. A first spring 94 is welded to the top of the connecting block 93. The top of the first spring 94 is welded to the sliding rack 92. A foot pedal rod 95 is welded to the bottom end of the sliding rack 92. A round hole 110 is opened on one side of the sliding rack 92. A fastening bolt 120 is threadedly connected to one side of the long plate 70 and inserted into the round hole 110.

[0019] In this embodiment, the foot pedal lever 95 consists of a long frame, a screw, and a circular foot plate. The screw is threaded to the bottom of the long frame, and the circular foot plate is welded to the bottom of the screw. It has a height adjustment function to meet different practical needs. The fastening bolt 120 and the circular hole 110 serve as a safety measure to prevent accidental activation of the igniter 80. The igniter 80 can be swung by foot and extended into the heat-insulating long cylinder 30.

[0020] Specifically, the igniter 80 includes an igniter body 81, with a long tube 82 integrally connected to the bottom end of the igniter body 81, a top rod 83 integrally connected to the rear side of the long tube 82, and an on / off button 84 provided at the other end of the igniter body 81.

[0021] In this embodiment, the igniter body 81 is fixedly connected to the gear 91 (it can be welded or screwed). By driving the gear 91 to rotate, the igniter body 81 can be driven to swing, thereby facilitating subsequent ignition.

[0022] Specifically, the elastic sealing mechanism 60 includes a slider 61 that is slidably connected to one side of the quenching furnace body 10.

It can absorb some heat for recycling and reuse, and at the same time, it can also recycle and purify some of the heat and harmful gases flowing into the air from the insulated long cylinder 30, thus playing a certain role in energy conservation and environmental protection.

[0026] The working principle and usage process of this utility model are as follows: Open the main valve of the gas cylinder. The operator can stand in front of the quenching furnace body 10, reverse the fastening bolt 120 to separate it from the round hole 110, open the branch valve on the gas supply structure 20, place the blower on the air inlet on the long plate 70, and then press down on the foot pedal lever 95. The sliding rack 92 moves down and drives the gear 91 to rotate. The first spring 94 is stretched elastically, and the entire igniter 80 swings upward. The top rod 83 first contacts the sealing arc plate 63. At this time, the sealing arc plate 63 is pushed and slides upward in an arc shape with the slider 61. The flame outlet end of the long tube 82 extends into the heat preservation long cylinder 30. When the start / stop button 84 contacts the protrusion 100, the start / stop button 84 is squeezed and automatically starts the igniter 80. At this time, a flame is generated in the quenching furnace body 10. Release the foot pedal lever 95, the sealing arc plate 63 resets and closes the opening 50 again, and the igniter 80 automatically resets and closes.
