The gear is fixedly connected to the outer wall of the fixing rod, and the gear is used for fixing and connecting a fixing mechanism; a fixing mechanism is arranged at the upper end of the gear, the fixing mechanism comprises a connecting block, a connecting groove, a C-shaped clamping seat and a tooth groove, the C-shaped clamping seat is inserted into the outer wall of the fixing rod, the connecting block is integrally formed on one side of the C-shaped clamping seat, and the connecting block is used for being connected with a current sensor. According to the utility model, through arranging the fixing mechanism, the sensor fixing piece is fixed on one side of the connecting block, so that the situation that the sensor fixing piece needs to be independently installed in order to install the sensor fixing piece is avoided, and the surge protection device can be rotated through the position of the surge protection device, so that the surge protection device is fixed at each position.

The utility model relates to the field of automobile plastic pipe joint, disclose a kind of quick installation's automobile plastic pipe joint, including metal ring, the left and right sides of the metal ring are all fixedly connected with annular, the end of the annular is provided with plastic pipe, the inside of the annular is slidably connected with the ring, the one end of the ring is inserted in the inside of plastic pipe, the one end of the ring inside is provided with sealing assembly, the sealing property between plastic pipe and annular is improved by sealing assembly, the top side of the outer wall of the ring is provided with positioning assembly, the position of the ring is fixed by positioning assembly, the left and right sides of the metal ring are all fixedly connected with bellows.The utility model makes the sealing effect of joint from material characteristics and structure design two aspects guarantee and ensure the sealing property of joint under various working conditions, and makes the joint can be quickly installed, avoids the inconvenience of installation and disassembly due to the need of special tool for installation and disassembly because of bolt and other fixing parts.

The utility model relates to the technical field of furnace covers of sand furnaces, in particular to a wear-resistant and heat-insulating furnace cover of a fused magnesite furnace, which comprises a furnace cover body, a heat insulating plate is arranged at the bottom of the furnace cover body, the furnace cover body consists of a first wear-resistant layer, a base layer and a second wear-resistant layer, the first wear-resistant layer is positioned at the top of the base layer, and the second wear-resistant layer is positioned at the bottom of the base layer. The base layer is located on the top of the second wear-resistant layer, and the heat insulation plate is composed of a first heat insulation layer, a perlite heat preservation plate and a second heat insulation layer. According to the wear-resistant furnace cover, the first wear-resistant layer, the base layer and the second wear-resistant layer are matched with one another, so that the wear-resistant effect on the furnace cover body can be achieved when the furnace cover body is used, and the situation that the furnace cover body is damaged and cannot be normally used due to the poor wear-resistant effect of the furnace cover body is avoided; and through mutual cooperation of the heat insulation plate, the first heat insulation layer, the perlite heat preservation plate and the second heat insulation layer, the heat insulation effect on the furnace cover body can be achieved when the furnace cover body is used.

The utility model relates to the technical field of field management machines, in particular to a machine cover with a limiting structure for a four-wheel-drive field management machine, which comprises a concave plate, a sliding sleeve is sleeved in an inner cavity of the concave plate, a connecting rod is movably sleeved in an inner cavity of the sliding sleeve, a handle is arranged at the top of the connecting rod, a limiting hole is formed in an inner cavity of the connecting rod, and the limiting structure is arranged in the limiting hole. A left connecting plate is arranged on the left side of the top of the concave plate, a right connecting plate is arranged on the right side of the top of the concave plate, and a limiting rod is arranged in an inner cavity of the right connecting plate in a sleeved mode. When the height of the cover body needs to be adjusted, the fixing nut is screwed, the limiting rod is moved when the fixing nut is moved out of the limiting rod, the handle is pulled when the limiting rod is moved out of the limiting holes in the left connecting plate, the right connecting plate and the connecting rod, the connecting rod is driven to move through the handle, and the sliding sleeve assists the connecting rod to move. The cover body is driven by the connecting rod to move, and the cover body is matched with the sliding groove and the sliding rod in the concave plate to move.
