This utility model discloses a waterproof picnic mat for outdoor leisure, belonging to the technical field of outdoor picnic mats. It includes a picnic mat body with a multi-layer composite structure, comprising, from bottom to top, a bottom anti-slip layer, a support layer, an activated carbon layer, a cushioning layer, a protective layer, and a surface layer. The lower surface of the bottom anti-slip layer has multiple biomimetic nipple structures. The support layer adopts a modular splicing structure, composed of two long boards and two short boards. The bottom anti-slip layer and the support layer are connected by a detachable connection structure. Quick-fixing components are also provided at the four corners of the picnic mat body. This utility model, through the combination of a detachable support layer, an auxiliary anti-slip layer, quick-fixing components to further improve the fixing effect, and the activated carbon layer, cushioning layer, protective layer, and surface layer, significantly improves the picnic mat's anti-slip properties, stability, portability, and maintainability, making it suitable for various outdoor terrains such as grass and sand.

The utility model provides a prestressed carbon fiber cloth anchoring device. The prestressed carbon fiber cloth anchoring device comprises an anchoring mechanism arranged on a beam body, and the anchoring mechanism comprises a first mounting plate, a second mounting plate, a movable plate, a carbon fiber cloth body, two screws and two resistance strain gauges; the two screw rods are installed on the beam body, the two resistance strain gauges are installed on the two screw rods respectively, the first installation plate is installed at the bottom of the beam body, the second installation plate is installed at the bottom of the beam body, and the first installation plate and the second installation plate are distributed in a bilateral symmetry mode; the movable plate is installed at the bottom of the beam body and located between the first installation plate and the second installation plate. The prestress carbon fiber cloth anchoring device is high in installation speed, high in testing efficiency, excellent in anchoring performance and capable of making full use of the high-strength performance of the carbon fiber cloth. When prestress is applied, a stress and deformation double-control technology can be achieved, the prestress can be accurately controlled, and it is guaranteed that the high-strength performance of the carbon fiber cloth is fully exerted.

The utility model provides a novel invisible orthodontic appliance for integrally adducting anterior teeth in a tooth extraction case, which comprises a bracket-free invisible orthodontic appliance body, the thickness of a rear tooth area of the bracket-free invisible orthodontic appliance body is increased by 0.1-0.25 mm on the basis of the original uniform thickness, the thickness of a distal surface of a second molar is increased by 0.15-0.25 mm, and the thickness of the rear tooth area of the bracket-free invisible orthodontic appliance body is increased by 0.1-0.25 mm on the basis of the original uniform thickness of the bracket-free invisible orthodontic appliance body. According to the bracket-free invisible orthodontic appliance body, a falling prevention piece is designed at a tooth extraction position of the invisible orthodontic appliance, the falling prevention piece is wider in a position close to an occlusal surface and narrower in a position close to a gum, and the size of the falling prevention piece is matched with the change of a gap of the tooth extraction position. According to the application, the back tooth area is thickened on the basis of the original uniform thickness, and the distal surface of the second molar is thickened, so that the anchorage of the back tooth area can be enhanced, and meanwhile, as for the inclination of adjacent teeth in the tooth extraction gap, the anti-collapse piece which is wider in the position close to the occlusal surface and narrower in the position close to the gum is designed at the tooth extraction position; therefore, when the dental crowns of the adjacent teeth on the two sides incline towards the tooth extraction gap, the anti-tilting piece can generate an inclination resisting effect. According to the invention, through the optimal design of the accurate non-uniform thickness, the correction efficiency of the tooth extraction case can be improved.

The utility model is applicable to the field of oral medical instruments, and provides an orthodontic appliance, which comprises a palatal arch, a base plate mounted on the palatal arch and two bands capable of being respectively mounted on two molar teeth in the oral cavity, an insertion opening is formed in one side of the belt ring, and a fixing base is arranged on the side, opposite to the insertion opening, of the belt ring; the two ends of the palate arch are inserted into the insertion openings of the two belt rings respectively and then are connected with the insertion openings in a welded mode. Therefore, by optimizing the shape and the size of the palatal arch and the mode that the palatal arch and the insertion hole of the belt ring are welded after being inserted, stimulation of the appliance to soft tissues on the tongue side and in the oral cavity is reduced, and the comfort level of a patient is improved. Meanwhile, the anchorage effect of the molar is enhanced, and movement, torsion or inclination torque loss of the molar in the correction process can be prevented.

The utility model discloses an anchorage nail traction device, and relates to the technical field of medical instruments. The anchorage nail traction device comprises a nail body, a rope body and a traction hook; the nail body is used for being implanted into an alveolar bone; the middle part of the rope body is lapped on the side wall of the tail end of the nail body, and two sections, crossing the side wall of the nail body, of the rope body are mutually wound to form a spiral part for binding the rope body on the nail body; the tail of the traction hook is fixedly connected with the two ends of the rope body at the same time. The traction hook is used for hooking a traction piece. According to the anchorage nail traction device, the spiral part is formed through the rope body, the rope body can be rapidly connected with the nail body conveniently, the traction hook is arranged on the rope body and connected with the traction piece, rapid connection and separation of the nail body and the traction piece are achieved, the phenomenon that the rope body is connected with a binding head is reduced, and the anchorage nail traction device is simple in structure and convenient to use. And adhesion with the internal mucosa of the mouth of the patient is avoided, smooth proceeding of subsequent treatment work is ensured, and the treatment pain of the patient is reduced.
