5results about How to "Solve the shift" patented technology

This invention relates to electrical component connection devices, and more specifically to the field of circuit board connection device technology. It discloses a circuit board fixing device for communication engineering construction, comprising a circuit board body with positioning holes and a positioning part. The positioning part includes a mounting base plate with a bottom groove and a recessed groove on its inner wall. Two leaf springs abut against each other to form elastic support. A pre-reserved gap in the wedge groove of the wedge block and compensation block allows the device to adapt to the thickness deformation of the circuit board due to temperature changes. Simultaneously, the tension spring drives the clamping ring to always abut against the surface of the circuit board. The elastic deformation of the leaf spring and the displacement compensation of the wedge structure work together to solve the problems of damage to the circuit board due to excessive clamping at high and low temperatures or displacement due to excessive clamping, achieving an adaptive and stable clamping effect for the circuit board under temperature-changing environments.

This utility model relates to the field of artificial turf technology and discloses an artificial turf positioning and cutting device, including an operating table. Two parallel guide rails are mounted on the operating table, and a support frame and a mounting frame are slidably connected to the guide rails. A pressing mechanism for pressing and positioning the artificial turf is installed inside the support frame. Fixed seats are fixedly connected to both sides of the upper end of the mounting frame, and a lead screw is rotatably connected between the two fixed seats. A movable seat is threaded onto the lead screw, and the lower end of the movable seat passes through a groove opened on the support frame. A mounting plate is fixedly connected to the lower end of the movable seat, and a cutting blade is mounted on the mounting plate. This utility model solves the problems of operators being unable to press the artificial turf during cutting, leading to easy deviation, and the tendency for uneven cuts to result from hand tremors, pulling forces, and external forces.

The utility model discloses a newborn breathing machine pipeline fixing paste, which comprises a fixing paste body and a breathing machine pipeline, pasting blocks are arranged at the bottom of the fixing paste body, the pasting blocks are arranged on the left side and the right side, a notch is arranged in the middle of each pasting block, a nanometer adhesive layer is coated at the bottom of each pasting block, a magic tape thorn surface is arranged at the top of each pasting block, and fixing strips are respectively arranged on two sides of each notch. Velcro rough surfaces are arranged at the tail ends of the fixing strips, and the fixing strips penetrate through the top of the breathing machine pipeline and are tightly attached to opposite Velcro thorn surfaces. The nanometer glue at the bottom of the pasting block is attached to the forehead to achieve fixation, the air holes are formed in the surface of the pasting block, ventilation is good, and stuffiness is avoided; the two fixing strips which are arranged in a front-back staggered mode penetrate through the top of the breathing machine pipeline and are attached oppositely, double fixation of the breathing machine pipeline is achieved, the problems of displacement and backward pulling of the breathing machine pipeline can be solved, and operation is easy; the rubber strip is provided with a plurality of arc-shaped grooves, other pipelines can be fixed according to the mode, and the pipeline fixing device is simple in structure, ingenious in design and suitable for popularization.

The application relates to the technical field of semiconductor process control, and discloses an air jet device, a control method and system for preventing wafer displacement, and a control device, the air jet device is applied to a mechanical arm, a plurality of holes are arranged on the mechanical arm, and the air jet device is connected with the holes; the air jet device is used for jetting out gas from the holes of the mechanical arm, so that liquid films between the mechanical arm and wafers during loading and unloading of the wafers are eliminated. The application avoids water viscosity caused by liquid film effect, prevents wafer displacement during loading and unloading, ensures that the wafers can be stably and accurately grabbed to specified positions, and solves the problem that liquid films are easily generated between the mechanical arm and the wafers in a wet environment, and the wafers are displaced due to adhesion caused by the liquid films.

This application provides a multifunctional insole, including a fixing layer and a replacement insole. The fixing layer is sewn to the insole body and the inner sole of the shoe, solving the problem of displacement during walking and ensuring a stable fit between the foot and the insole. The Velcro at the top of the fixing layer and the adhesive layer at the bottom of the replacement insole form a detachable structure, facilitating the removal and cleaning of the replacement insole to maintain shoe hygiene. It also allows users to flexibly replace the replacement insole with one offering different functions such as height enhancement, warmth, breathability, and antibacterial properties, depending on their needs for daily commuting, sports, or special occasions. The combination of the forefoot cushioning pad and air cushion effectively reduces the impact force on the forefoot and heel during walking and jumping. At the arch, the insole body and support layer work together to provide precise support and resist torsion. The side wing pads generate counter-support when the foot tilts to the sides, limiting excessive inward or outward pronation and further enhancing stability during use.
