The invention discloses a front traction mouth device and a manufacturing method thereof, comprising: a pair of retaining components, each retaining component includes a retaining crown, a traction hook and a connecting rod, and the retaining crown is used to wrap one side of the mouth For the first premolar, second premolar and first molar, the traction hook is set on the buccal side of the retaining crown, and the connecting rod is set on the lingual side of the retaining crown; the hyperbolic reed, one end of which is connected to the On the connecting rod, the other end is used to abut against the lingual side of the incisor in the mouth; the screw expander, the two ends of the screw expander are respectively connected to the connecting rod of a retention component. This solution is more conducive to the stability of wearing the device in the front traction mouth. During the front traction, it can expand the arch and solve the crowding of the anterior teeth in combination with clinical needs, and improve the efficiency of orthodontic treatment.

The invention belongs to the field of rehabilitation medicine, and discloses an individualized auricle fixer after auricle reconstruction, including any one or both of the ear cranial groove and the concha cavity, an anti-scar material and a concave-convex structure; an anti-scar The material is coated on the surface of the ear cranial groove that is close to the ear skin; the concha cavity and the ear cranial groove are connected to each other; the concave-convex structure is located on the outer wall of the concha cavity, and the largest cross-section of the concha cavity is located in the concave-convex area. within the minimum section boundary of the structure. There is a gap between the boundary of the section of the concha cavity and the smallest circumference that can cover the boundary of the concave-convex structure. The invention avoids the problems of difficult cutting and low compliance of patients during the daily use of scar stickers; adopts the silicone gel coating with silicone, which strengthens the therapeutic effect on scars and reduces skin itching and discomfort induced by long-term wearing ; High fit, the special design of the concave-convex structure increases the wearing stability and the binding strength of the fixer.

The invention discloses a welding mask. The welding mask comprises a welding cap, an eye guard disposed at the front side of the welding cap, a filter disposed on the eye guard, and a head band assembly disposed in the welding cap, wherein the welding cap is movably connected with the eye guard; an eye guard adjusting device disposed on side portions of the welding cap and the eye guard; the eye guard adjusting device comprises an eye guard limiting disc fixed to one side of the front end of the welding cap, and an adjusting handle fixed to the eye guard and located at the same side with the eye guard limiting disc; a plurality of limiting teeth in divergent distribution are formed on the eye guard limiting disc; and the adjusting handle has one end embedded into the limiting teeth, and the other end serving as an operating end of the adjusting handle. The welding cap is capable of reducing the harm of smoke dust, toxic gas and noise to the body of the welding personnel to a large extent, and can be firmly worn on the head of the welding personnel; and the labor intensity in the welding process is reduced, and the production efficiency is improved.

The invention relates to the technical field of safety helmets, and discloses a safety helmet with a high-temperature-resistant structure and convenient to disassemble, the safety helmet comprises a safety helmet body, an annular groove is sectioned in the outer wall of the bottom end of the safety helmet body, and a fixing ring is fixedly connected to the middle wall surface of the annular groove in the bottom end of the safety helmet body; movable grooves are formed in the positions, corresponding to the middles of the sliding plates, of the outer wall of the fixing ring, center shafts are fixedly connected to the inner walls of the side faces of the movable grooves, the outer walls of the center shafts are sleeved with rotating rings, push plates are fixedly connected to the bottom ends of the rotating rings, connecting rods are fixedly connected to the top ends of the rotating rings, and fin radiators are fixedly connected to the ends, away from the rotating rings, of the connecting rods. When the safety helmet body is in a high-temperature state, a wearer turns over the fin radiator out through simple operation of pulling the sliding ring, then the fin radiator makes contact with the outer wall of the safety helmet body, and heat dissipation and cooling are conducted on the safety helmet body through the heat dissipation function of the fin radiator. The influence on the work and the body of a wearer caused by high-temperature accumulation of the safety helmet body is avoided.
