This utility model relates to the field of stacker crane protection technology, and discloses an anti-collision mechanism for stacker cranes, including two sets of first anti-collision plates, and two sets of symmetrical second anti-collision plates inserted between the two sets of first anti-collision plates. Two sets of symmetrical fixing elements are arranged in the space between the first and second anti-collision plates. The stacker crane requiring anti-collision protection is placed in the space between the first and second anti-collision plates. Then, the hydraulic rod is activated, and its extension end extends forward. When the protrusion contacts the stacker crane, the limiting plate drives the rotating shaft to rotate. The protrusion rotates towards the inner wall of the moving frame around the center of the rotating shaft. The limiting plate drives the adjusting rod to slide inward along the middle end of the sleeve and retracts. The adjusting rod compresses the first spring. Under the reverse elastic force of the first spring, the impact force generated by the contact between the protrusion and the stacker crane can be buffered, avoiding direct hard contact between the protrusion and the stacker crane, thus preventing damage to the stacker crane.

The utility model discloses an ABS board anti -static electricity packaging device belongs to anti -static electricity packaging technical field, including packing box main part, the inside of packing box main part is equipped with buffer sponge, one buckle groove is equipped with respectively in the both sides of buffer sponge, the inside of packing box main part both sides respectively slidingly connected with a limit stop, packing box main part's both sides are connected with a screw rod respectively, the utility model discloses setting packing box main part, buffer sponge, buckle groove, carousel, screw rod and limit stop, when using, the carousel is rotated, and then carousel rotation drives screw rod to rotate, along with the rotation of screw rod, will drive limit stop and move in packing box main part inside, and then gradually snap -on into the buckle groove on buffer sponge, and the effect of limit stop is played to buffer sponge, thereby on one hand avoided the unstable arrangement of buffer sponge because of the plug -in mode, on the other hand also avoided the inconvenient dismounting because of the glue stick, make the arrangement of buffer sponge more convenient.

The switch shell comprises a shell body, a heat dissipation groove is formed in the bottom of the shell body, a plurality of fins are arranged in the heat dissipation groove, and the size of all the fins in the groove depth direction of the heat dissipation groove is smaller than or equal to the groove depth size of the heat dissipation groove. The fins are arranged in the heat dissipation grooves in the bottom of the shell, it is ensured that the sizes of the fins in the groove depth direction of the heat dissipation grooves are smaller than or equal to the groove depth sizes of the heat dissipation grooves, the fins are effectively prevented from protruding out of the shell of the exchanger, and therefore in the packaging and transporting process, the fins cannot be scratched or collided with packaging materials, the risk of packaging damage is reduced, and the service life of the exchanger is prolonged. And the appearance integrity and reliability of the product are improved.
