DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with the specific implementation mode.

[0020] For example, Figures 1-4The high-temperature tunnel furnace shown is for drying speaker mesh, and comprises a conveying mechanism 1 and a furnace cover 2. The furnace cover 2 is fixedly mounted on the upper surface of the conveying mechanism 1, and a motor 3 is fixedly mounted on the upper surface of the furnace cover 2. A guide tube 5 is fixedly mounted on the upper surface of the furnace cover 2 and on one side of the motor 3. Inspection doors 4 are movably mounted on both side surfaces of the furnace cover 2, and a connecting piece 6 is fixedly mounted on the upper surface of the inspection door 4. A mounting seat 7 is fixedly mounted on the upper surface of the furnace cover 2 and near both sides, and a lifting plate 8 is movably mounted inside the mounting seat 7.

[0021] The connecting member 6 includes a pad 601 and a connecting plate 602. The pad 601 is fixedly installed on the lower surface of the connecting plate 602 and near both ends. The upper surface of the connecting plate 602 and near both ends are provided with positioning holes 603; the inner two sides of the mounting seat 7 are provided with rod grooves 701, and the inner part of the rod groove 701 is fixedly installed with a guide rod 702. The surface of the guide rod 702 is provided with a spring 703, and the spring 703 has an upward thrust on the sleeve block 801; the two end surfaces of the lifting plate 8 are fixedly installed with sleeve blocks 801, and the upper surface of the lifting plate 8 and near both ends are fixedly installed with positioning holes 603. Block 802, an extension block 803 is fixedly installed on the front surface of the lifting plate 8; the sleeve block 801 is sleeved on the surface of the guide rod 702, the lower end of the spring 703 is fixed to the inner lower surface of the rod groove 701, and the upper end of the spring 703 is fixed to the sleeve block 801; the positioning block 802 is embedded in the positioning hole 603, and the connecting member 6 is movably connected to the inspection door 4 through the pad 601. The cooperation of the positioning block 802 and the positioning hole 603 can limit the connecting member 6 and the inspection door 4. Since the positioning block 802 has a certain height, the inspection door 4 cannot be flipped open.

[0022] It should be noted that the present invention is a high-temperature tunnel furnace for drying speaker meshes. During use, when the inspection door 4 needs to be opened, the extension block 803 is pressed down to lower the lifting plate 8. After the lifting plate 8 drops to a certain height, the positioning block 802 on the lifting plate 8 will withdraw from the positioning hole 603 of the connecting piece 6, so that the inspection door 4 can be flipped open. When closing the inspection door 4, the inspection door 4 is directly flipped closed. The inspection door 4 will use the connecting piece 6 to press down the lifting plate 8 until the positioning block 802 of the lifting plate 8 is automatically embedded in the positioning hole 603, so that there is no need to manually lock the closed inspection door 4.
