The invention relates to an anti-falling seal ring. A protruding part is arranged on the cross section of the anti-falling seal ring, a hollow part is arranged in the middle of the cross section of the anti-falling seal ring, and the protruding part is slightly nearer to the mounting end of the anti-falling seal ring than the hollow part. The invention further relates to a lamp seal structure. According to the anti-falling seal ring and the corresponding lamp seal structure, the sea ring is prevented from falling through being additionally provided with the protruding part and the hollow part, thereby overcoming the defects of troublesome and inconvenient remounting of the existing seal ring which is easy to fall from a mounting position due to the absence of the anti-falling function.

The invention provides ultra-thin run-resistant underwear produced by adopting a cylinder loom and a production process of the ultra-thin run-resistant underwear. The production process comprises the following steps: (1) wrapping by taking spandex as inner-wrapped silk and taking polyamide as outer-wrapped silk to obtain a wrapped yarn; (2) weaving: weaving the wrapped yarn by adopting the cylinder loom comprising a stocking machine to obtain a stocking blank; (3) sewing: cutting and sewing the socking blank to obtain stockings, so as to facilitate subsequent dyeing and sizing; (4) dyeing: bagging and dyeing the stockings to obtain colorful stockings; (5) sizing: sizing the colorful stockings by adopting an underwear sizing plate and endowing the colorful stockings with run-resist functions; (6) cutting: cutting the sized stockings according to a sample plate and cutting each of the stockings into two sleeveless underwear bodies; (7) sewing. In addition, the invention further provides the underwear produced by the production process. On the premise of not increasing the novel equipment investment, an ordinary cylinder loom (comprising the stocking machine) is directly adopted for producing the underwear, so that high quality and inexpensiveness are realized.

The invention provides a paperboard fixing mechanism used for paper printing. A top column is welded to the rear side of the top end of a print press, and a printing plate is arranged at the bottom end of the top column; motors are embedded in the left and right sides of the middle portion of the top end of the print press; the surfaces of the outer walls of the motors are covered with a conveyingbelt; fixed blocks are embedded in the middle portion of the top end of the conveying belt; containing grooves are embedded in the left and right sides of the middle portions of the fixed blocks; spring columns are welded to the bottom ends of the containing grooves, and receiving plates are welded to the top ends of the spring columns, and arc buckles are welded to the top ends of the receivingplates; rolling balls are embedded in the surfaces of the inner walls of the containing grooves; anti-falling plates are integrally arranged at the bottoms of the inner walls of the top ends of the containing grooves; the bottom ends of the anti-falling plates are provided with limiting rods; and containing plates are welded to the top ends of the limiting rods, and torsion hinges are embedded tothe middle portions of the containing plates. The whole device is stable in structure, has good limiting capacity, and is convenient to use and operate, and capable of fixing paperboards and increasing the flattening rate of paperboard printing.

The invention discloses a self-locking anti-disengagement nut which comprises a nut body. An anti-disengagement band is integrally arranged at one end of the nut body and axially provided with a self-locking groove. A self-locking conical face is integrally arranged at the end, close to the nut body, of the anti-disengagement band. The anti-disengagement band is sleeved with a lock pad. The middleof the lock pad is axially provided with a lock pad through hole. The end, away from the nut body, of the lock pad is axially provided with a positioning groove. The positioning groove communicates with the lock pad through hole. The nut body is locked through the cooperation of the lock pad and the self-locking conical face. By means of the technical scheme, the self-locking anti-disengagement nut is reasonable in structural design, simple in structure, convenient to install, reliable in connection, good in anti-disengagement performance, good in antitheft effect and high in practicability.

The invention relates to a large-diameter stainless steel stay cable and a manufacturing method thereof. The large-diameter stainless steel stay cable comprises a stainless steel stranded wire and twopressure pipe joints, wherein an inner hole is formed in the pressure pipe joints, and the inner hole of the pressure pipe joints is composed of an inclined hole and an equal-diameter hole; the diameter of the inclined hole is gradually reduced from the end part to the middle, and the minimum diameter of the inclined hole is the same as the diameter of the equal-diameter hole; center wires at thetwo ends of the stainless steel stranded wire are correspondingly sleeved with conical plugs, the two ends of the stainless steel stranded wire correspondingly penetrate into the inner hole of the pressure pipe joints and are formed into one body with the pressure pipe joints through compression, and the diameter of the stainless steel stranded wire is 36-80 mm. According to the large-diameter stainless steel stay cable, a novel production process is adopted so that the pressing type large-diameter stainless steel stay cable with the diameter of 36-80 mm can be machined, the product parameters such as the minimum breaking tensile force and the like meet relevant regulations, furthermore, the appearance is round, and the appearance is more attractive.

The invention discloses an inorganic bonding system for water-based environment-friendly brazing flux, which comprises the following components in terms of mass percentage: Na 2 O 15%~20%, SiO 2 48%~65%, component A 0.1%~1%, Fe 2 o 3 0-0.1%, moisture 12%-36%; the component A includes CaO and MgO, and the mass ratio of CaO and MgO is 1:0.5-2. The invention also discloses the application of the inorganic bonding system for the water-based environment-friendly brazing flux in the preparation of coated brazing filler metal. The invention also discloses a coating composition for brazing material, which includes brazing flux and the inorganic bonding system for the water-based environment-friendly brazing flux. The invention also discloses a sheathed brazing material, which comprises a brazing material as an inner core and a sheath covering the brazing material, spraying the brazing material coating composition onto the surface of the brazing material and drying That is, the covered brazing filler metal is obtained.
