The utility model relates to the technical field of protective supports, in particular to an anti-collision heavy material rack vehicle. The device comprises a bottom plate, universal wheels and a frame body, a protection device is arranged on one side of the bottom plate, the protection device comprises a shell, one end of the shell is fixedly connected with the bottom plate, rubber plates are fixedly connected to the two sides of the shell, fixing frames are fixedly connected to the two sides of the shell, and the rubber plates are fixedly connected to the two sides of the shell. A honeycomb-shaped rubber plate is fixedly connected to the inner side of the fixing frame, two telescopic rods are fixedly connected to one side of the fixing frame, a protection plate is fixedly connected to the output ends of the two telescopic rods, a sponge plate is fixedly connected to one side of the protection plate, and the arc surfaces of the telescopic rods are sleeved with springs. The two ends of the two springs are fixedly connected with the fixing frame and the protection plate correspondingly. The problems that a traditional heavy material rack vehicle does not have the anti-collision performance, and due to the fact that the traditional heavy material rack vehicle usually bears a large number of goods and cannot effectively buffer impact during collision, the vehicle shakes violently easily, and goods transportation is affected are solved.

The utility model relates to tablet computer technical field, put forward a kind of tablet computer with anti-falling effect, including installation protective sleeve, the surface of installation protective sleeve is equipped with square groove, the inside of square groove is provided with double-shaft micro motor, the both ends of double-shaft micro motor are all sleeved with bevel gear, upper and lower side in square groove are equipped with round bar, the left end of round bar is also equipped with bevel gear, and round bar is sleeved with. Built-in instantaneous speed inductor and micro motor drive mechanism, automatically trigger in the moment of falling, the whole screen is sunken, air bag is landed first, avoid glass direct collision. No. 2 air bag (front) directly absorbs impact;No. 1 air bag (back) is quickly transferred to no. 2 air bag by gas communication pipe and is pressed gas, realizes secondary buffering, and impact force is dispersed by two stages. Protective film and rubber support block and double air bag sunken mechanism form the triple line of defense of "film-shell-air", give consideration to front, back and edge drop scene, significantly improve the overall anti-falling life.

The utility model relates to the technical field of bridge fabrication machines, in particular to a bridge fabrication machine running limiting device with a buffering function, which comprises a mounting seat, a supporting plate arranged at the upper end of the mounting seat, a first buffering plate arranged on the front side of the supporting plate, and a second buffering plate arranged on the rear side of the first buffering plate. A shock absorber is arranged between the first buffer plate and the second buffer plate, a damper is arranged on the rear side of the second buffer plate, movable plates are arranged on the two sides of the damper, movable blocks are arranged at the rear ends of the movable plates, a guide sliding rod is arranged on the surface of the supporting plate, and fixing pieces used for being connected with the supporting plate are fixedly installed at the two ends of the guide sliding rod. A first spring and a second spring are arranged on the outer side of the guide sliding rod; impact force borne by the first buffer plate is preliminarily buffered through the shock absorber, the second buffer plate drives the movable plate to deflect, the movable block slides on the surface of the guide sliding rod, and the elastic force of the first spring and the elastic force of the second spring are matched with the damper, so that secondary buffering of the impact force is achieved.

The utility model belongs to the field of electronic engineering especially relates to a shock attenuation buffer circuit board, including bottom plate, frame and circuit board body, bottom plate fixedly connected in the lower part of frame, its bottom surface keeps flush with frame, circuit board body is placed in the inside of frame and slides, the many corners of bottom plate and circuit board body all are equipped with an installation groove, and the installation groove on circuit board body and the installation groove on bottom plate are vertically aligned. Through the buffer structure that contact plate, fin group and damper constitute, the external vibration energy is effectively absorbed, the stability and service life of circuit board body under high vibration environment are significantly improved, at the same time, through the cooperation of limiting frame, guide rod, sliding plate, press plate and return spring, the compression fixed of circuit board mounting bolt is realized, prevents the loosening or falling of bolt due to vibration, thereby improves the reliability and security of overall structure.
