The utility model discloses a lightweight mounting bracket assembly of an electronic vacuum pump for an automobile, and belongs to the technical field of automobile accessories. The automobile electronic vacuum pump light-weight installation support assembly comprises a support body and four fixing frames, a transverse frame plate is installed on one side of the upper end of the support body, an automobile vacuum pump is arranged in the transverse frame plate, a positioning arm is installed on one side of the lower portion of the support body, and cross arms are arranged at the upper ends of the fixing frames. The electronic vacuum pump assembling and disassembling support solves the problems that an existing electronic vacuum pump assembling and disassembling support is complex in structure and inconvenient to assemble and disassemble and affects maintenance efficiency, the positions of the cross arm and the pressing plate are adjusted, the position stability of the cross arm and the pressing plate is kept through the spring damping rod and the hydraulic spring, the upper end of an automobile vacuum pump is limited, and the maintenance efficiency is improved. Connecting pieces on the two sides of the automobile vacuum pump are pressed above the transverse frame plate and limited through the cross arm and the positioning arm, the position is kept stable, and the mounting and dismounting efficiency is improved.

This utility model discloses a multifunctional fire hose, including a hose. The hose features a continuous array of arched protrusions in its anti-slip layer, periodically arranged along the hose's axis, providing multidirectional and continuous friction. This effectively reduces slippage when firefighters push, pull, or twist the hose, making the operation more reliable. The vents in the protective layer ensure good air permeability while preventing dust and debris from entering, providing reliable protection for the load-bearing layer. The first color-changing zone in the load-bearing layer, relying on an activated carbon adsorption layer and chemically sensitive capsules, can promptly indicate the presence of toxic gases. The second color-changing zone, aided by a conductive tape and a heat-sensitive capsule, can quickly indicate high-temperature areas. These two color-changing zones are staggered along the hose and, with the separation of spacers, achieve independent responses, avoiding interference between signals. This allows firefighters to quickly and accurately assess on-site risks, significantly improving the safety and overall efficiency of firefighting operations.

This utility model relates to the field of high-voltage power transmission and distribution technology, and discloses an adjustable-capacity high-voltage series compensation device, including a core compensation unit, a bypass protection unit, a damping circuit, and a control system. The core compensation unit has at least two parallel capacitor branches controlled by independent switching switches for step-wise adjustment of the compensation capacity. The control system includes a safety interlocking system, which includes a first interlocking module and a second interlocking module that are independent of each other. The first interlocking module is used to forcibly lock all independent switching switches in the open state when the bypass switch is closed; the second interlocking module is used to prohibit operation of the incoming and outgoing line isolating switches of the device when the bypass switch is not closed. This utility model, by combining hardware forced interlocking with intelligent control, eliminates the risk of misoperation and significantly improves the safety, reliability, and adaptability of the device operation to the power grid.

The utility model relates to a bra mould cup, concretely is a kind of bra mould cup of automatic adaptation to multiple chest, including bra mould cup body, the plurality of moulding lines of being formed on bra mould cup body, the plurality of moulding lines on bra mould cup body is formed with notch along first direction.The notch is cut out on the moulding line of first direction end portion, so that bra mould cup body can be opened with the size of different amount of chest, when the crowd wearing of small chest, the notch is not opened, to keep the supporting effect of existing bra mould cup body, when the crowd wearing of large chest, the notch of bra mould cup body is opened, to adaptively expand the cup edge length of bra mould cup, to eliminate the problem of bra mould cup body to wearer to cause chest compression, to effectively improve the use comfort of wearer, while improving the application range of bra mould cup body.

The utility model discloses a kind of composite functional 4T polyester staple fiber and spinneret, belong to chemical fiber spinning equipment technical field. Including plate body, guide hole structure and spiral distribution groove, guide hole structure is set on plate body and is provided with several, spiral distribution groove is communicated with guide hole structure, wherein, guide hole structure is used to spray out polyester staple fiber. The utility model improves guide hole structure in spinneret, the guide hole unit in guide hole structure is in 4 groups T shape structure, and four groups T-shaped guide hole unit is symmetrically distributed and the vertical end of T shape is crossed, at this time, the fiber shape that is sprayed through spinneret should be kept approximately with guide hole unit distribution form, so that the cross section of fiber forms four T-shaped structures of symmetric distribution, four T-shaped structures can simultaneously support and deform when fiber deformation, so that fiber can still maintain certain resilience and support after long time use.

The application discloses a kind of super-soft high-elasticity hot melt films with skin-friendly, it relates to hot melt film technical field, the super-soft high-elasticity hot melt film with skin-friendly, raw material is by weight percentage, including as follows component: SBC class (SEBS, SEPS, SIS, SBS) elastomer: 45%-75%;TPU: 20%-35%;Compatibility agent (maleic anhydride grafting SIS / SBS class): 2%-10%;Paraffin oil or naphthenic oil: 2%-5%;Tackifying resin (carbon 5 or carbon 9): 1%-5%;Antioxidant: 0-0.5%;Ultraviolet absorber 0-0.5%, solve the current market commonly used female sports underwear hot melt film elastic band rebound is not good, not soft enough and without skin feeling, skin quality, Q feeling problem.The hot melt film of the application has high tensile rebound elasticity, super-soft, strong skin feeling, good Q elasticity;The hot melt film of the application is used for the lamination of sports underwear fabric, has good bonding strength, washability, service lamination, the application has high tensile rebound elasticity, so that underwear hot melt film has good tensile rebound performance.
