The application relates to the technical field of locks, and discloses a lock box structure convenient to assemble, which comprises a box body, side plates and a cover plate. The side plates are arranged on the outer walls of the two sides of the box body, the cover plate is arranged on the outer walls of the box body and the side plates, the outer wall of the cover plate is provided with a locking mechanism, the locking mechanism comprises a traction rod one, a first connecting rod, a first clamping block, a traction rod two, a second connecting rod and a second clamping block, the traction rod two and the traction rod one are rotationally connected to the middle outer wall of the cover plate through pivots, and the two first connecting rods are rotationally connected to the outer walls of the two ends of the traction rod one. In the utility model, dovetail grooves and sliding blocks are matched to realize the preliminary connection of the box body and the side plates, positioning grooves and positioning blocks are matched to realize the preliminary positioning of the cover plate, the knob of the locking mechanism is used for driving the connecting rod to drive the clamping block to clamp the clamping groove to complete locking, the complicated screw tightening operation is not needed, the assembly process is greatly simplified, and the assembly efficiency is remarkably improved.

This invention discloses an automated warehouse racking system, belonging to the field of warehousing technology. It includes a storage rack and a railcar. The railcar is equipped with a lift, and the output end of the lift is equipped with a loading platform. The output end of the loading platform is equipped with an adjusting rod and a conveying assembly. The storage assembly includes a storage container and a lifting assembly, with several first electric rollers installed inside the storage container. This invention offers two operating modes: single-item direct retrieval and multi-item continuous retrieval. In scenarios involving scattered / urgent items, goods can be directly transferred via the conveying assembly without temporary storage via the storage assembly, resulting in a short operational chain and fast response speed. In scenarios involving batch operations, multiple items can be temporarily stored via the storage assembly, allowing for the retrieval of multiple items in a single round trip, significantly reducing the number of round trips by the stacker crane and improving overall operational efficiency.

This invention belongs to the field of orthodontic instrument technology, specifically a periodontal targeted near-infrared light bimaxillary therapy device that protects tooth crowns. It includes a protective brace and a bimaxillary irradiation device. The protective brace includes a maxillary protective brace and a mandibular protective brace, each comprising a lingual plate and a labial plate. The labial plate includes a cervical sleeve and a receiving groove. The bimaxillary irradiation device includes an outer irradiation plate, an inner irradiation plate, and a flexible occlusal plate. Near-infrared laser lamps are installed on the outer and inner irradiation plates. This invention achieves simultaneous irradiation of the labial and lingual periodontal tissues of both jaws, significantly improving orthodontic efficiency. It can simultaneously irradiate the entire periodontal area of ​​both jaws in a single treatment, eliminating the need for separate upper and lower jaw procedures, shortening treatment time, achieving simultaneous activation of all periodontal tissues, and improving tooth movement efficiency. The bimaxillary irradiation device uses precise lamp placement according to the periodontal ligament area, working in conjunction with the protective brace to fully cover the protective crown, synergistically avoiding thermal and light damage.

The invention provides a drainage intercepting device, which relates to the technical field of water resource management, and comprises a culvert box, an intercepting mechanism, a chain scraper conveyor, a bucket and a transfer mechanism, the closure mechanism is mounted in the culvert box; a through opening is formed in the top of the culvert box, mounting plates are mounted on the two sides of the top of the through opening, the chain plate conveyor is mounted between the two mounting plates, the top end of the chain plate conveyor extends out of the culvert box, the chain plate conveyor blocks a channel of the culvert box, one side of the chain plate conveyor faces water, and the other side of the chain plate conveyor faces water. The multiple buckets are installed on chain plates of the chain plate conveyor respectively. And the transferring mechanism is used for transferring and receiving the solids excavated by the excavator bucket. The chain scraper conveyor drives the excavator buckets on the chain scraper conveyor to dig solid pollutants in water flow on the upstream side and then convey the solid pollutants to the downstream side, the transfer mechanism receives the solids falling from the excavator buckets, concentrated collection of the solids is completed, unified cleaning of the solid pollutants is facilitated, and the problem that the solids of a traditional drainage facility are scattered and difficult to clean is solved.
