This utility model discloses a high-precision digital sensor keypad switch keyboard, characterized by: including a PCB board, on which at least one digital magnetic sensor keypad switch is disposed; and on which a digital magnetic sensor is disposed, capable of linearly and accurately detecting the change in magnetic flux in the Z-axis direction caused by the height difference of the permanent magnet within the keypad switch, and quantifying it into a digital sample value to generate a high or low level digital signal output. The digital magnetic sensor and the keypad switch are configured in a one-to-one correspondence. The purpose of this utility model is to overcome the shortcomings of the prior art and provide a digital magnetic sensor keypad switch keyboard with a simple structure, low cost, effectively reducing the wobbling amplitude during the keypad's movement stroke, high triggering accuracy and reliability, relatively low frictional resistance, good tactile feel, and ultra-low latency.

The application relates to the technical field of high polymer fiber rope manufacturing, and discloses a preparation process of a double-twisted anti-rotation ultra-high molecular weight polyethylene rope, which comprises the following steps: high-strength high-modulus UHMWPE fibers are selected as main body reinforcing fibers and are subjected to surface activation treatment; the treated UHMWPE fibers are divided into inner layer fiber bundles and outer layer fiber bundles; the blended inner layer fiber bundles are bundled, introduced into a tubular stranding machine through a tension controller, twisted in an "S" direction, and inner layer strands are formed; the twisted inner layer strands are continuously passed through a first heat treatment zone and cooled to form a pre-consolidated inner layer strand core. Through the combination of the double-layer blending functionalization, the inner-outer reverse twisting structure and the heat-induced plasticity integrated technology, the high-performance UHMWPE rope with high interface bonding strength, excellent anti-rotation performance, stable structure and intelligent monitoring potential is prepared, a series of problems such as weak interface bonding, easy rotation, single function and difficult monitoring are effectively solved, and the comprehensive performance and reliability of the UHMWPE rope are remarkably improved.

An eccentric shaft assembly for a passenger bus inward-swinging door includes an eccentric base. An eccentric shaft bracket is connected to the bottom of the eccentric base, and a door panel is connected via the eccentric shaft bracket. An eccentric hole is provided on the eccentric base, and a roller support rod is disposed within the eccentric hole. An eccentric shaft assembly roller is fitted to the end of the roller support rod, and the eccentric shaft assembly roller is slidably disposed in a door panel track groove. The eccentric shaft bracket includes a door panel mounting plate and an eccentric shaft mounting plate, which are connected by a connecting plate. The eccentric base is installed at an eccentric position on the eccentric shaft mounting plate. Compared with the prior art, this utility model has the following advantages: The development of this eccentric shaft structure for a passenger bus inward-swinging door satisfies the door leaf adjustment function through a redesigned structure. Simultaneously, the structural design is more rational, eliminating exposed bolts and improving the appearance quality of the door product.
