The utility model provides a flexible LED decorative lamp based on a flexible silica gel substrate, which relates to the technical field of LED lamps, and comprises a decorative lamp strip and a winding column, end hollow rings are fixed at the top and the bottom of the winding column, and the inner wall of each end hollow ring is rotatably connected with a base rotating seat. The mode of installing the L-shaped pressing piece is adopted for solving the problems that an existing bendable LED decorative lamp is usually transported and stored in a curled mode in design, due to the fact that the thickness of a lamp strip is large, when a traditional adhesive tape is used for trying to fix, firm bonding is often difficult to achieve due to insufficient viscosity; if a ribbon is adopted for binding, the lamp strip is easily damaged due to the fact that the contact area between the ribbon and the lamp strip is small, in addition, the curled lamp strip is fixed through the ribbon, operation is quite difficult, the phenomenon of slipping easily occurs in the using process, the lamp strip needs to be cut according to specific requirements, and the cost is low. Therefore, the remaining lamp strip is difficult to effectively fix and easy to scatter, the user experience is reduced, and the working efficiency is also influenced.

The utility model discloses a temporary supporting foundation widening structure, and particularly relates to the technical field of building widening, which comprises a supporting column, an adjusting widening plate arranged on the supporting column, a fixed widening plate fixedly arranged at the top end of the supporting column, a first connecting block fixedly welded at the bottom end of the adjusting widening plate, and a first connecting groove arranged at the top end of the supporting column. A first sliding groove is formed in the bottom wall of the first connecting block, a first sliding block is slidably connected into the first sliding groove, a first connecting base is fixedly connected to the bottom wall of the first sliding block, a second sliding groove is formed in the side wall of the supporting column, a second sliding block is slidably connected into the second sliding groove, and the first connecting base is fixedly connected to the surface of the second sliding block. A second supporting inclined column is rotationally connected between the two first connecting seats; according to the arrangement of the structure, the widening plate can be disassembled, so that the situation that the transportation cost is increased due to the fact that the storage occupied space is large during transportation is avoided, and the width of the whole device can still be adjusted subsequently according to design requirements after the whole device is constructed.

This invention provides a vacuum composite LNG cryogenic pipeline, comprising four functional layers from the inside out: an inner composite pipeline layer, a vacuum layer, an outer composite pipeline layer, and an outer sheath layer. The inner composite pipeline layer consists of an inner spiral wire layer, a sealing layer, a braided layer, another sealing layer, and an outer spiral wire layer, arranged sequentially from the inside out. The vacuum layer is formed by an annular area between the inner and outer composite pipeline layers, supported by an insulating gasket ring, providing vacuum insulation. The outer composite pipeline layer consists of inner and outer spiral wire layers as its innermost and outermost layers, a sealing layer as its second layer, and a braided layer as its third layer. The outer sheath layer comprises an outer sheath. This invention offers superior bending flexibility and low bending stiffness, making it less prone to fatigue damage under external tensile and bending cyclic loads. It also provides excellent insulation, more rational stress transmission in cryogenic pipelines, and a wider range of applications.
