This invention discloses a SIA St self-anchoring rubber ring. The invention utilizes the cooperation of a main rubber strip and steel tooth blocks, with the oblique teeth of the steel tooth blocks ensuring smooth insertion of the insertion tube. Upon further pressure, the oblique teeth of the steel tooth blocks press tightly against the outer wall of the insertion tube, preventing slippage. Compared to existing rubber rings made of a single material, the steel tooth blocks and oblique teeth provide a much stronger clamping effect. The main rubber strip not only connects the steel tooth blocks but also prevents deformation or wear that could reduce the clamping effect. Finally, the self-anchoring rubber ring is integrally formed from the main rubber strip and several steel tooth blocks through spraying, drying, molding, and vulcanization. After molding, the back end of the steel tooth block partially overlaps with the back connection surface of the main rubber strip. This manufacturing method ensures a stable connection between the steel tooth blocks and the main rubber strip, preventing separation of the steel tooth blocks and ensuring excellent integrity and connection stability of the entire self-anchoring rubber ring.

The utility model relates to related technical field of house car accessories especially, house car side desk, including mounting bracket, the inner wall rotation of mounting bracket is connected with two rotating shafts, and the surface fixed connection of two rotating shafts has movable table board. The house car side desk, through the setting of auxiliary assembly, in use, can utilize auxiliary mechanism under the premise of not influencing movable table board itself available space to increase movable table board's available area, and can separate the space and movable table board, and the convenient placement different object carries out the distinguishing operation, support mechanism can improve the stability when using auxiliary mechanism, will not appear the situation of collapse, in addition through the setting of stabilizing assembly, can utilize the stable support force dispersion movable table board on object weight for the tensile force of mounting bracket of the vacuum chuck negative pressure adsorption, ensure the stability of movable table board in the use process, will not appear movable table board on the pressure too big leads to the situation that mounting bracket and house car outer surface separate.

The utility model discloses a steel brush type metal wire surface grease cleaning device which comprises a bearing seat, two deep groove ball bearings are installed on the inner side of the bearing seat, a driven belt wheel shaft is fixed to the inner sides of the two deep groove ball bearings, a metal wire polishing block is fixed to one end of the driven belt wheel shaft, and the other end of the driven belt wheel shaft is provided with a steel brush. And two fixed shells which are rotationally and symmetrically distributed are arranged on the inner side of the metal wire polishing block. Metal wires to be cleaned penetrate through the driven belt wheel shaft and the middle of the cross-shaped mounting groove in the metal wire polishing block, the metal wires penetrating through the cross-shaped mounting groove in the metal wire polishing block are clamped and fixed through the four steel wire brushes, and then the driven belt wheel shaft and the metal wire polishing block are driven by the belt to rotate. And a steel wire brush in the metal wire polishing block rotates around the outer surface of the metal wire and removes grease on the surface of the metal wire, so that the metal wire is cleaned, and no cleaning missing area exists on the surface of the metal wire in the cleaning process.

The application discloses a composite graphene lightning-resistant material and a preparation method and application thereof. 5 ~10 6 The composite graphene lightning-resistant material has a graphene sheet orientation degree of more than 90%, an electrical conductivity of 10 5 ~10 6 S / cm and a thermal conductivity of 1200-1800 W / m·k. The graphene thick film serves as a physical oxygen barrier in a macroscopic manner, and blocks the penetration of air to a resin pyrolysis zone. When lightning strikes, the extremely high in-plane conductivity induces the rapid dispersion of the current along the surface in a radial manner, thereby avoiding the large-scale aggregation of charges at the breakdown point. Meanwhile, the carbonized layer formed by the heat of the flame-retardant resin impregnated in the micropores is tightly combined with the graphene sheet, thereby constructing a gradient protection system integrating the conductivity, the thermal conductivity and the flame retardation.

The present invention discloses a two-stage parachute structure for ammunition parachutes, which belongs to the technical field of parachute applications. The two-stage parachute structure includes a first-stage parachute structure and a second-stage parachute structure. By using the corresponding arrangement of the two parachute structures, the combination arrangement and sequential operation of the two-stage parachute can be realized, thereby realizing the secondary deceleration of weapons and ammunition, ensuring that the dynamic load of the weapons and ammunition before the main parachute is opened does not exceed a certain value, avoiding damage to the parachute fabric, the ammunition structure, and the internal instruments and meters of the ammunition due to excessive dynamic load when the main parachute is opened, and ensuring the normal operation of the parachute system and the ammunition. The two-stage parachute structure for ammunition parachutes of the present invention has a simple structure, is easy to set up and control, can effectively realize the normal operation of weapons and ammunition under transonic or supersonic conditions, ensures the normal operation of the parachute main parachute, the ammunition structure, and the internal instruments and meters of the ammunition, improves the reliability and stability of the operation of weapons and ammunition, and has good application effects and promotion value.
