Description

Technical Field

[0001] The utility model relates to the field of sealing, in particular to a sealing device for an automatic focus finder. Background Art

[0002] The traditional UGI water-gas furnace automatic focus detector usually relies on its own weight to detect when in use. Therefore, it is not advisable to use excessive external force to hinder the free downward movement of the detection rod to avoid excessive impact on the detection accuracy.

[0003] Traditional automatic focus detectors usually use a packing seal structure. In order to achieve a sealing effect, the packing needs to be pressed as tight as possible. This can easily cause the detection rod to get stuck or move slowly when moving downward, and it cannot accurately reflect the actual height of the carbon layer, which in turn affects the operation of the furnace.
