Description

High temperature furnace door opening device

technical field

The invention relates to a high-temperature furnace, in particular to a device for opening a high-temperature furnace door.

Background technique

Traditionally, the doors of high-temperature furnaces used in laboratories are manually opened and closed on the left and right, while high-temperature furnaces in factories use doors that open on both sides. Since human hands directly touch the handle on the furnace door, burns are very likely to occur when opening and closing the furnace door at high temperature. In addition, between the furnace door and the furnace body or the furnace doors that open on the left and right sides, a latch structure is used when the furnace door is closed. This structure is easily deformed due to high temperature, which will increase the resistance when the furnace door is opened and closed. Next, the difficulty of opening and closing the furnace door increases significantly.

detailed description

In order to facilitate those skilled in the art to better understand the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. The following is only exemplary and does not limit the protection scope of the present invention.

A high-temperature furnace door opening device, including a support rod 16, a first rotating shaft 6, a manual locking handle 19 and a support mechanism; wherein the support rod 16 is arranged transversely on the top of the high-temperature furnace door 18, and one end of the support rod 16 is used for connection For the opening and closing mechanism that makes the high-temperature furnace door 18 open, the other end of the pole 16 is connected with the cable 17 fixed on the high-temperature furnace body; the first rotating shaft 6 is arranged at the lower end of the high-temperature furnace door 18, and can The door 18 rotates; the high-temperature furnace door 18 can be opened or closed downwards around the first rotating shaft 6 through the control of the opening and closing mechanism; the manual locking handle 19 is arranged on the high-temperature furnace body with the side of the cable 17. When the door 18 is closed, it can be stuck on the pole 16; the support mechanism is arranged below the high-temperature furnace door 18, including the support plate 11 and the turning shaft 14 that makes the support plate 11 turn left and right. The first rotating shaft 6 is connected to drive the turning shaft 14 to rotate.
