The invention discloses a shock absorbing device for automobiles, comprising an outer cylinder, an inner cylinder, a piston slidingly sealed in the inner cylinder, a flow passage member sealed at the bottom of the inner cylinder, and a valve cover. an annular liquid cavity, the flow-over component is provided with a damping hole that communicates the inner cylinder cavity with the annular liquid cavity, the valve cover can be slid up and down on the flow-over member to close or open the orifice, and the bottom of the piston An anti-bottoming piece is connected, and the anti-bottoming piece has a non-contact downward force on the valve cover during the process of descending with the piston and approaching the valve cover, so that the valve cover closes the damping hole to prevent the further descending of the piston; During the downward movement of the piston rod, the non-contact downward force is exerted on the valve cover through the anti-bottoming element, so that the valve cover is sealed in the damping hole, the damping fluid stops flowing from the inner cylinder to the annular liquid chamber, and the piston stops downward, preventing the piston rod from descending. Bottom out to avoid shock bottoming when driving on rougher surfaces.

It relates to a water-saving method including an improved automatic pressure regulator, because the automatic pressure regulator (58) is sequentially provided with a filter screen (58d), a water-through inner plug (58c), a movable pressure regulator (58) from the water inlet to the water outlet Plug (58a), pressure regulating spring (58f), return water pressure chamber (58g), water reaches the nozzle after the automatic pressure regulator, and the water pressure required by the movable pressure regulating plug (58a) at the water outlet nozzle is greater than and When it is equal to the water pressure provided by the water inlet end, under the action of the pressure regulating spring (58f), it is away from the filter screen (58d) and the water inner plug (58c) to ensure the maximum water flow; when the water outlet nozzle and water When the water pressure required by the device is lower than the water pressure provided by the water inlet end, the excess water will flow into the return water pressure chamber (58g) and push back the movable pressure regulating plug (58a) under the action of back pressure to approach the water return pressure chamber (58g). Said water-through inner plug (58c) is until pressure balance on both sides, promptly protects water outlet nozzle and water device to be beneficial to water saving and pressure overload protection.

The invention discloses a stop mechanism for a transfer gripper in an offset press. The stop mechanism comprises a transfer roller, a transfer arm, a gripper opening and closing mechanism, and a protection mechanism. The gripper opening and closing mechanism comprises a driving gear, a gripper opening and closing control cam, a pair of driving swing bars, and a swing bar cam, wherein the driving gear and the gripper opening and closing control cam are fixedly mounted on a drive side shaft end of the transfer roller, one end of each driving swing bar is fixedly mounted on a swing bar shaft and the swing bar cam is mounted on a camshaft. The protection mechanism comprises a stop cylinder mounted on the inner side of a transmission side wallboard, a V-shaped swing bar, a stop link and a stop swing bar. The V-shaped swing bar is rotatably mounted on the inner side of a drive side wallboard through a pile head. One end of the V-shaped swing bar is hinged to a piton rod of the stop cylinder, and the other end of the V-shaped swing bar is hinged to one end of the stop link. The other end of the stop link is hinged to one end of the stop swing bar. The other end of the stop swing bar is fixed to the camshaft. The stop mechanism is capable of avoiding waste paper in case of an anomaly of paper on a discharge board.

The invention discloses a crawler type magnetic adsorption cable detecting robot. The crawler type magnetic adsorption cable detecting robot comprises a framework, a V-shaped rubber crawler, a clutch, a falling speed limiting device and at least two V-shaped loading wheels, wherein the V-shaped rubber crawler is coated on the periphery of all the V-shaped loading wheels; magnetic adsorption units are packed in the V-shaped rubber crawler; one or more V-shaped loading wheels are driving wheels; the falling speed limiting device is connected with one of the V-shaped loading wheels through the clutch; the framework comprises machine frames which are symmetrically arranged on two sides of the V-shaped rubber crawler; and each of the machine frames adopts a two-section type structure. Through the adoption of the structure of the crawler type magnetic adsorption cable detecting robot disclosed by the invention, the structure is compact, the operation is simple and convenient, and the obstacle surmounting capacity is high; the derailing preventing capacity of the robot can be improved by the V-shaped rubber crawler; the magnetic adsorption units are packed in the V-shaped rubber crawler, so that the collision between the crawler and the surface of a pull cable can be buffered; besides, according to the radius of the loading wheels, the diameter of the magnetic adsorption units is designed, so that the phenomena of impacting generated when the crawler goes around the loading wheels can be avoided. In addition, the falling speed can be adjusted, and the crawler type magnetic adsorption cable detecting robot disclosed by the invention can adapt to the push cables in different inclinations.
