The utility model discloses a retractable door shield, which belongs to the technical field of door shields and comprises at least two partition sheets, a connecting component and a ratchet mechanism, and the connecting component enables one partition sheet to be slidably connected with the other partition sheet; at least one rack is arranged on the surface of one partition piece, a through groove is formed in the surface of the other partition piece, a gear is rotatably connected in the through groove, and the gear is meshed with the rack; the ratchet mechanism is arranged in the through groove, connected to the gear and used for driving the gear to move in the first direction. When the ratchet mechanism rotates anticlockwise to a preset angle, the ratchet mechanism is separated from the gear, the gear moves towards the second direction, and under the driving of the ratchet mechanism, the gear drives one partition piece to move towards the first direction, so that the door stop extends; the ratchet mechanism is rotated anticlockwise to a preset angle, so that the ratchet mechanism is separated from the gear, the user can push one partition piece to move in the second direction, the door shield is shortened, and the door shield can be suitable for door openings and aisles with different widths.

The utility model discloses a Chuzhou chrysanthemum turnover drying device which comprises a guide rail arranged on the left side of the drying device, two sliding blocks are slidably connected to the front portion and the rear portion of the top of the guide rail respectively, a fixing plate is fixedly connected between the two sliding blocks which are opposite in the front-back direction, and a ceramic motor is fixedly installed on the left side of the top of the fixing plate on the left side. A rotating rod is fixedly installed on an output shaft of the ceramic motor, and a bearing plate is welded to the top of the fixing plate located on the right side. According to the Chuzhou chrysanthemum drying device, a large amount of Chuzhou chrysanthemums can be contained through the arrangement of the multiple overturning discs, the Chuzhou chrysanthemums are directly conveyed to an inner cavity of the drying device to be dried through the cooperative use of the guide rails and the sliding blocks, and the Chuzhou chrysanthemums are dried through the cooperative use of the ceramic motor, the rotating rod, the rotating column, the first bevel gear and the second bevel gear; and the overturning disc is overturned and dried in the inner cavity of the drying device, so that the Chuzhou chrysanthemums can be effectively and uniformly dried, and the drying efficiency is improved again.

The utility model relates to the field of automobile design and manufacturing technology, concretely is a kind of automobile bumper spraying frock, including first branch leg, and the inner wall of one of fixed sleeve is rotatably connected with first screw rod, and the other end of first screw rod is fixedly connected with rotating rod, and the outer wall of rotating rod is equipped with movable sleeve, and the surface of movable sleeve is fixedly connected with second branch leg.Compared with prior art, by setting fixed sleeve, first screw rod, second screw rod, movable sleeve, rotating rod, threaded block, rotating assembly, limiting assembly and fixed assembly, by rotating carousel, so that second screw rod drives first screw rod to rotate by rotating rod, so that threaded block moves towards or opposite, then by adjusting fixed assembly and limiting assembly, so that the tooth slot on limiting plate is separated from gear, then by rotating assembly, two support rods are adjusted, it is very convenient to use, and the technical problem of stepless adjustment of support rod can be realized without punching.

The invention relates to the technical field of sampling devices, and discloses a sampling device and a conveying method for oil additive production, which solves the problem that additives at different positions may be different, and when sampling is performed at only one position, there is a singleness, which affects the actual detection effect and leads to a low measurement accuracy. The invention comprises an additive sampling and collection box body, a sampling and collection box cover is provided on the top of the additive sampling and collection box body, a uniform stirring and mixing component is provided on the sampling and collection box cover, a liquid discharge pipe is provided on the additive sampling and collection box body, a valve is provided on the liquid discharge pipe, a liquid inlet pipe is provided on the additive sampling and collection box body, and a sampling movable pipe is provided on one side of the additive sampling and collection box body; different positions in the additive to be detected are sampled simultaneously, and the additive to be detected in the additive sampling and collection box body is stirred by the uniform stirring and mixing component, thereby improving the accuracy of sampling measurement.

The utility model discloses a disconnecting switch hand-operated device for preventing misoperation, which comprises a disconnecting switch main body and a rotating rod rotatably connected inside the disconnecting switch main body, the surface of the disconnecting switch main body is provided with a rotating groove, the outer surface of the rotating rod is fixedly provided with a bearing, the outer surface of the bearing is fixedly connected with a fixing ring, and the fixing ring is fixedly connected with the rotating groove. Belongs to the technical field of power equipment. According to the utility model, through the arrangement of the slidable rotating cylinder, when the rotating rod does not need to be rotated manually, the positioning block can be prevented from being meshed with the clamping groove through the adsorption of the second magnet and the first magnet, even if the rotating cylinder rotates, the rotating rod cannot be rotated, misoperation is avoided, and the safety is enhanced; and by arranging a sliding rod capable of sliding, when the sliding rod pops up, through a cross shape formed by the sliding rod and the rotating cylinder, the rotating cylinder can be conveniently rotated, and the practicability is enhanced.
