2results about How to "Avoid shock damage" patented technology

The utility model relates to a segment protection device for shield construction, including support seat and prefabricated segment, the top of support seat all is established with the clamping slot for the prefabricated segment joint, the surface of support seat near prefabricated segment all is fixedly connected with first protective pad for supporting prefabricated segment, the bottom of support seat is fixedly connected with a plurality of positioning column, the surface of support seat is established with a plurality of positioning slot for the positioning column insertion. The utility model discloses through support seat, prefabricated segment and first protective pad cooperation, the camber of clamping slot is adapted to prefabricated segment, first protective pad is used for buffering shock attenuation and improves frictional resistance simultaneously, improves the stability of support seat support prefabricated segment, through positioning slot and positioning column cooperation, the stability of prefabricated segment vertical stacking is improved to improve space utilization rate, and the end cap is sleeved in the both ends of prefabricated segment and prevents the collision, thereby improves the safety of segment conveying and storage in narrow space.

The utility model relates to the technical field of packaging boxes, in particular to a drawing type wine display packaging box which comprises a packaging box body, a drawing assembly capable of being drawn is installed in the packaging box body in a sliding mode, and a containing accessory groove plate is fixedly installed at the bottom of the packaging box body. A side plate is fixedly mounted on one side of the flip plate, negative magnetic strips are fixedly mounted on the outer wall of the side plate, and the negative magnetic strips on the outer wall of the side plate are detachably connected with the positive magnetic strips; the drawing assembly comprises a supporting plate, a guide rail set and an inner wine box body, the supporting plate and the guide rail set are installed in a sliding mode, the two sets of inner ball plates are movably installed between the outer sliding rail and the inner sliding rail, the inner wine box body is detachably installed on the upper surface of the supporting plate, and a bottle body embedding groove is formed in the inner wine box body. Through the re-adsorption of the side plates and the positive magnetic strips and the combined design of the ball plates and the inner sliding rails, the drawing can be easily carried out by a single hand, the problem of blockage caused by the reduction of adsorption force of a traditional magnetic attraction structure is avoided, and the display effect is improved.
