1:1前所使川的膨胀螺柃包括膨胀螺钉以及与之相配的螺母和膨 胀套管， κ屮膨胀螺钉螺栓说水端为圆台型钉头或者设置为圆台型螺 母，所述膨胀套符 近圆 钉头或圆台型螺母的 ·端幵有多个纵向 槽 1」， 就足说膨胀¾ ^的 ·端被分割成书多个膨胀筋， \ 端为管 .， 使用时， 拧紧膨胀蟝钉或螺母， 圆台型钉头或圆台型螺母自小端至大 端 入所说膨胀套 ^内， 迫使其膨胀筋 .锥形膨胀变形， 并膨胀丁安 装孔内。  Before 1:1, the expansion screw of Sichuan made the expansion screw and the matching nut and expansion sleeve. The κ屮 expansion screw bolt said that the water end is a round table type nail head or a round table type nut. The end of the near-round nail head or the round-plate nut has a plurality of longitudinal grooves 1", so that the end of the expansion 3⁄4 ^ is divided into a plurality of expansion ribs of the book, and the end is a tube. When used, the expansion boring nail is tightened. Or nut, round table type nail head or round table type nut from the small end to the big end into the expansion sleeve ^, forcing its expansion rib. Conical expansion deformation, and expansion of the ferrule installation hole.
就金属膨胀套管来说，这种膨胀弯曲变形不会闵为外力的消火而 消火， 山 Γ膨胀^ 膨胀 装孔内， 丄丄小 i^ 'r安装孔外， 想耍取出 膨胀螺栓， 只能强行拉动带有圆台型钉头或者圆台型螺母， 这样膨胀 套钤会进 膨胀」'ί'·紧紧的 在安装孔内， 这种怙况卜， 如果继续增 人拉力， 必将损坏墙而和各种载体， 强行取出的膨胀螺拎难以再次使 川。  In the case of a metal expansion sleeve, this expansion and bending deformation does not cause fire suppression by external force, and the expansion of the haw is in the expansion hole, and the small hole is installed outside the hole, and it is necessary to remove the expansion bolt. It can forcibly pull the nut with a round table type or a round table type, so that the expansion sleeve will expand into the ''ί'· tightly in the mounting hole. If this continues, the wall will be damaged. However, with various carriers, it is difficult to force the snails to be taken out again.

These expansion bolts stuck on the wall or the ground and the road surface give us production and living. The inconvenience caused by the Bungee, and the strict currency: the impact of Guan Guan, people ι'ί. Try to solve the ten. W problem, now the market I: now 丫 - kind of 1:1 tapping screw and plastic expansion The combined expansion screw of the pipe is characterized in that the upper part of the plastic expansion sleeve is a tubular shape having an inner diameter larger than that of the A tapping screw, and the lower part is provided with two adjacent expansion ribs. When used, the plastic expansion sleeve is provided with an expansion rib. One end is inserted into the mounting hole. When the self-tapping screw is screwed, the self-tapping screw is screwed on the inside of the expansion rib; the other side forces the two expansion ribs to bend to the sides, so that the end of the plastic expansion sleeve The expansion is in the installation hole. When disassembling, the self-tapping screw can be screwed out. This expansion screw is affected by the plastic material, and its strength is limited. The capacity is 3⁄4 from the installation hole, and the small energy can carry the person i 'N'j, j LL plastic expansion sleeve ;
