This utility model discloses an emergency lane isolation device for highways, comprising multiple cylinders placed on the emergency lane isolation line. Each cylinder has four U-shaped walls at its top. A hollow tube is placed within the inner cavity of the U-shaped wall between adjacent cylinders. The inner cavity of the U-shaped wall has an annular groove. Both ends of the hollow tube have U-shaped strips adapted to the annular groove. A limiting component is provided on one side of the inner cavity of the U-shaped wall. This utility model places the cylinders to the side of a disabled vehicle, and the hollow tubes are placed within the inner cavity of the U-shaped walls on the cylinders. The U-shaped strips on the surface of the hollow tubes insert into the surface of the annular grooves within the inner cavity of the U-shaped wall. The hollow tubes compress a triangular block, causing it to rotate into the inner cavity of the limiting groove. After the hollow tube is fully inside the inner cavity of the U-shaped wall, the triangular block returns to its original position due to its own gravity and is located above the end of the hollow tube. The multiple cylinders working together with the hollow tubes enhance the warning effect.

The utility model discloses a high -efficient mould pressing device for mosquito incense forming belongs to mosquito incense production equipment technical field, including fixed mode, the one side of fixed mode is provided with the plastic shaping groove of accommodating material, the other side of fixed mode is provided with the sliding mode and pusher and is slidably arranged, and pusher slidingly penetrates into plastic shaping groove, is used to push material and slides out plastic shaping groove, and the sliding mode is detachably connected with a plurality of limiting rods that penetrate into the slot wall of plastic shaping groove, limiting rod can slide along the slot wall of pusher and slide out plastic shaping groove in the same direction, and limiting rod resets slower than pusher. The utility model discloses a high -efficient mould pressing device for mosquito incense forming, and mosquito incense will be guided to fall on the platform by limiting rod after leaving plastic shaping groove, because a plurality of limiting rods separate the structure of mosquito incense layer after layer winding, make the structure of mosquito incense not easy to stack because of its relatively long structural characteristics.
