This utility model discloses a sliding button mechanism and an adjustable adsorption force POS machine base connection device and POS equipment. The ingenious design utilizes a mating component on the back of the POS machine and a permanent magnet within the POS machine base. The magnetic attraction state is altered by changing the relative position of the permanent magnet and the mating component, ensuring the POS machine is stably positioned when placed on the receiving part of the POS machine base. Furthermore, the permanent magnet is attached to the sliding button mechanism and placed within the mounting cavity of the POS machine base. The sliding engagement state of the connecting frame and connecting plate of the sliding button mechanism switches between the first and second states of the permanent magnet and the mating component on the POS machine. This design is not only convenient to implement and compact, but also easy to install. The adsorption force generated between the permanent magnet and the iron connecting frame increases the positional stability of the sliding button mechanism. Additionally, the metal plate-like connecting frame can be reused as a counterweight for the POS machine base, further enhancing the stability of the device.

The utility model discloses a coring device for road detection, which comprises a supporting bottom plate, a lifting mechanism, universal wheels and moving wheels, and a guide mechanism is arranged at the top end of the supporting bottom plate; the lifting mechanism is connected to the outer wall of the guide mechanism in a sliding mode, a core taking part is arranged between the lifting mechanism and the wire guiding mechanism, and the core taking part drives the lifting mechanism to vertically move through rotation; the universal wheel is arranged at one end of the bottom of the supporting bottom plate; the multiple sets of moving wheels are horizontally and symmetrically arranged at the other end of the supporting bottom plate, and a sliding adjusting mechanism is arranged between the moving wheels and the supporting bottom plate. The sliding adjusting mechanism is arranged at the connecting position of the moving wheel and the supporting bottom plate, the moving wheel can be adjusted in the vertical direction through the sliding adjusting mechanism, when the moving wheel needs to be used for moving supporting, the moving wheel only needs to be lowered, and if coring supporting needs to be carried out, the coring supporting can be carried out conveniently. And if not, the moving wheels are adjusted upwards to exceed the bottom end of the supporting bottom plate, so that stable implementation of coring operation is guaranteed.

This invention belongs to the field of materials heat treatment technology, specifically relating to a heat treatment method, microstructure, and microstructure control method for α-solidified TiAl alloy castings. This method targets α-solidified TiAl alloy castings with unstable lamellar microstructure obtained from metal mold casting. It involves hot isostatic pressing under high temperature and high pressure conditions, utilizing the high-pressure environment to promote atomic diffusion and eliminate casting defects, completely transforming the unstable lamellar microstructure into a stable near-γ microstructure dominated by blocky γ phase. This step replaces the traditional process of water quenching and oil quenching, which are highly prone to cracking and are necessary to destroy the stable lamellar structure. Subsequently, seven cycles of "heating-short-time holding-air cooling" are performed in the upper part of the α+γ two-phase region below the α phase transformation point of the alloy, utilizing the cyclic phase transformation from γ to α to (α+γ) to achieve successive grain splitting and refinement. This invention eliminates the risk of stress cracking during heat treatment at its source, is suitable for complex thin-walled castings, and can obtain a fine-grained near-lamellar microstructure.
