Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of dissecting tables, especially to a winding cover plate for being installed on a dissecting table. BACKGROUND

[0002] The experimental dissecting table is a device for storing human specimens to facilitate experiments, and the utility model application file with the publication number CN115245433 A discloses a laboratory dissecting table capable of automatically opening and closing a cover. The cover plate of the laboratory dissecting table mainly comprises a plurality of parallel slats and elastic connecting strips. The elastic connecting strips connect the slats. However, this cover plate has the following technical defects: 1. The two ends of the cover plate are exposed, and the elastic connecting strips may slide out due to loosening; 2. The two ends of the slats frequently rub in the guide grooves, which easily causes wear of the slats. The support effect of the guide grooves on the worn slats is not ideal, and due to different degrees of wear, some slats are supported by the guide grooves, while some slats are suspended. The suspended slats are directly supported by the elastic connecting strips, which causes large deformation of the elastic connecting strips and eventually leads to connection failure; 3. The current slats have a relatively large volume after being wound, which results in a large space occupied by the winding mechanisms at both ends of the dissecting table, affecting the use of the dissecting table.
