A storage structure and a refrigerator. The storage structure (43) for a refrigeration device comprises: a cabinet assembly (10) having an open end (13); a cabinet cover (20) arranged at the open end (13) of the cabinet assembly (10) and movable between a closed position and a maximum open position relative to the open end (13); a return drive assembly (30) operably connected with the cabinet assembly (10) and the cabinet cover (20) and configured to apply a driving force to the cabinet cover (20) to enable the cabinet cover (20) to automatically return when the cabinet cover (20) moves to a preset stroke position towards the closed position under the action of an external force. The preset stroke position is between the closed position and the maximum open position.

This invention discloses a multi-disciplinary collaborative design method for power grid engineering based on data fusion, relating to the field of collaborative design technology. The method includes: receiving professional design data and constraint data; performing object merging to generate an object library and a constraint library; reading the object library and constraint library to generate candidate object pairs, obtaining the relationships to be established, and generating a callable clearance ledger; receiving local design modifications, generating change domains, calculating penetration values, recalculating the clearance amount after local modifications, identifying review relationships, boundary-breaking relationships, existing abnormal relationships, and objects to be repaired; generating a change domain to accept changes and performing boundary-breaking propagation; obtaining a set of review relationships, a set of boundary-breaking relationships, a set of existing abnormal relationships, and a set of objects to be repaired; establishing a list of objects to be repaired, generating correction domains and correction content, locking the responsible professional, writing back to the object library, updating the callable clearance ledger, and triggering a correction closure check; improving the consistency, traceability, and closure of multi-disciplinary collaborative design.

The application discloses a hollow perfusion screw assembly for fixing collapsed or crushed fracture of non-spinal load-bearing bone, which comprises a screw body, characterized in that a perfusion channel is arranged in the screw body; the screw body is provided with a plurality of bone cement release openings which are asymmetrically distributed on the stem along the axial direction and / or the circumferential direction of the screw body; at least part of the bone cement release openings are oblique holes, long circular holes or strip-shaped holes, and have different opening directions or hole diameters; the bone cement enters the fracture lines between large bone blocks, the fracture lines between the large bone blocks and small bone blocks which are not directly fixed by the screw, the fracture lines between small bone blocks, the gaps between crushed bone and / or the collapsed cavities through the release openings, forms a directional extension filling and bonding structure, and forms a composite load-bearing structure together with the screw body and the main bone frame.

This invention discloses a linear stapler with precise firing and positioning, relating to the field of staplers. In this invention, the staple cartridge is installed within a staple cartridge holder via adjusting bolts. The height of the staple cartridge within the holder can be adjusted by raising and lowering the bolts, thereby adjusting the distance between the staple cartridge and the anvil plate. This allows the staple cartridge and anvil plate to work together to clamp and cut tissues of different thicknesses, improving the applicability of the stapler. Furthermore, an adjusting plate is installed on the side of the staple cartridge, and this adjusting plate is connected to the firing assembly via a lifting plate. When the staple cartridge is adjusted, the firing assembly can be adjusted in height using the adjusting plate and the lifting plate, ensuring that the height of the firing assembly is adjusted synchronously with the staple cartridge. This guarantees that the firing assembly can accurately fire the titanium staples within the adjusted staple cartridge, ensuring the normal operation of the stapler. Simultaneously, the adjustment of the staple cartridge's height allows for quick and convenient adjustment of the clamping position of the staple cartridge and anvil plate on the tissue.

The application provides a waterproof construction method for the joint of a water-rich geological anti-floating anchor rod and a foundation, and relates to the technical field of anti-floating anchor rod connection. Step 1, preparing materials; step 2, after excavation is completed, the anti-floating anchor rod is constructed according to the designed position, and then a cup-shaped foundation is formed around the anti-floating anchor rod by manual excavation; step 3, after the base layer is cleaned, a concrete foundation cushion is poured, and a polyurethane waterproof layer is brushed on the foundation cushion, with the brushing thickness being controlled within 1.5-2 mm; step 4, water-swelling waterproof adhesive tape, steel plate waterproof tape, waterproof steel plate and reinforcing steel bars are additionally arranged at the bending position on the anti-floating anchor rod; step 5, then, the cup-shaped foundation is poured with slightly-expanding concrete; step 6, after pouring is completed, SBS waterproof coiled material and a waterproof protective layer are constructed on the bottom cushion of the foundation bottom plate and the upper part of the cup-shaped foundation; and step 7, after construction is completed, the foundation bottom plate steel bars are bound and the foundation bottom plate concrete is poured. The application is used to solve the problem of waterproof leakage at the joint of the anti-floating anchor rod and the foundation.
