The passive self-adaption magnetorheological deceleration strip can adjust the rigidity of the deceleration strip at real time and automatically according to the vehicle speed of the vehicle and have no obstruction action to the vehicle at low speed, the comfort is increased, the vehicle and deceleration strip are protected for reducing the speed for the vehicle at high speed for having the reasonable reminding and punitive action.

The invention discloses a sealing device for spicy fish packaging bags. The sealing device comprises a first sealing device and a second sealing device, wherein the second sealing device is arranged at the upper end of the first sealing device; after packaging bag sealing is finished, a pressing rod can be pressed downwards to enable a first limited block to start to retract along a slope groove;and when the first limiting block retracts and then moves to one side of a connecting hole, the first limited block can be clamped in an inner cavity of the connecting hole under the action of the elastic force of a second spring, so that the first sealing device and the second sealing device can be closed and self-locked, and an operator is prevented from accidentally touching a lower sealing component and an upper sealing component to cause damage.

The invention discloses a roll goods transportation fixing device which comprises a device body. First fixing bases are arranged on one set of lateral faces of the device body and second fixing basesare arranged on the other set of lateral faces of the device body. A limiting rod is welded between the fixing bases on each set of opposite faces. Adjusting belts are welded between the device body and the first fixing bases as well as between the device body and the second fixing bases. In the roll goods transportation fixing device, the first fixing bases and the second fixing bases are symmetrically provided with bolts and are in threaded connection with the adjusting belts welded on the device body through bolts, a bottom plate is welded at the bottom of the device body, the position of the limiting rods can be adjusted through the adjusting belts according to specific sizes of roll goods, meanwhile, rigid contact between the limiting rods and the roll goods can be effectively reducedthrough elastic rubber annularly wrapping the limiting rods, by means of the structure, the fixing device can be better attached to the roll goods for fixing, and abrasion to the goods is reduced while the possibility of shaking of the goods is reduced.

The invention discloses a magnesium alloy refining crucible with improved purity and its application in the field of metal processing, in order to overcome the disadvantages in the prior art that the magnesium alloy is only in the preliminary processing state and the metal performance of the magnesium alloy is not up to standard, in order to overcome this defect The technical solution includes a refining crucible body with an elliptical cross-section, and the refining crucible body is provided with a feed inlet, a stirring and diverting device, and a cryogenic treatment chamber in sequence along the material supply direction, and the stirring and diverting device includes a circular cross-section The inner ring rotor and the circular gear driving the inner ring rotor, the inner ring rotor meshes with the circular gear, and the bottom end of the inner ring rotor has an arc-shaped notch, and an arc-shaped rotating plate is fixedly connected to the inside of the notch. Compared with the traditional refining crucible, the technical solution utilizes the circumferentially rotating inner ring rotor to perform hot rolling treatment on the magnesium alloy, which reduces the molecular gap inside the magnesium alloy and improves the metal properties of the magnesium alloy.

The invention discloses a clamping device for welding a stop plug pipe, comprising a lower die, a first power part for driving the lower die to vertically move, an insulation seat and a second power part for driving the insulation seat to vertically move; the lower die comprises a base and two bearing blocks which are arranged at the top of the base and extend upwards; the two bearing blocks are oppositely arranged at intervals; an accommodating cavity for placing a stop plug is defined by the top of the base and the two bearing blocks; and the insulation seat is located above the lower die and is used for pressing a pipe placed on the stop plug. By using the clamping device, the phenomenon that a current flows through the insulation seat and is conducted to the pipe can be avoided in the welding process, and the condition that the top of the pipe is damaged by the current can be reduced; in addition, the insulation seat is made of POM plastic, so that the damage to the top of the pipe can also be reduced, and the surface quality of the pipe can be further improved.
