The present invention provides a support device for laying long rails on large slopes, belonging to the technical field of rail laying. It includes two bottom shells, and the two bottom shells are placed on a base. A support mechanism is arranged on the bottom shell, and the side surface of the bottom shell is attached to the vertical surface of the concrete sleeper. By setting the support mechanism, a round roller and a limit block are installed on the support mechanism. When it is necessary to remove the support mechanism, only need to pull the pull rope. The pulling of the pull rope will cause the round roller to tilt downward through the rotating assembly. In this way, the friction between the round roller and the long rail will be significantly reduced. At the same time, the limit block will also contract inward, effectively avoiding the situation of jamming between the limit block and the long rail. Under the dual effects of the above-mentioned reduction of friction and elimination of the risk of jamming, by continuously pulling the pull rope, it is possible to easily pull out the adjacent two support mechanisms from the bottom of the long rail, making the whole operation process more simple and efficient.

This application provides a seat foam and a seat. The seat foam includes a foam A-side, which is the side of the foam closest to the occupant. A functional area is disposed on the foam A-side, and the functional area has at least one transition surface, which is a small plane with an angle A greater than or equal to 90 degrees to the foam A-side. A preset area is used to configure a sheet-like occupant sensing device, and the preset area is the orthographic projection area of ​​the sheet-like occupant sensing device on the foam A-side. A stress concentration area is a stress radiation area that overlaps with the functional area and the preset area. A stress relief part is a cut located in the stress concentration area, at the junction of the foam A-side and the transition surface outside the preset area, for stress relief. This solution uses a cut to release stress in the stress concentration area, which not only ensures the flatness of the seat when sitting, but also releases stress protection elements in a timely manner, achieving the dual effect of meeting both seat design requirements and user experience requirements.

The invention relates to a rapid connection node device of a modular assembly type building structure, and belongs to the technical field of building connecting pieces. The rapid connection node device of the modular assembly type building structure comprises a steel corbel, penetrating holes are formed in the two internal corner end faces of the steel corbel, and high-strength bolts connected with the penetrating holes in an inserted mode are arranged on the two internal corner end faces of the steel corbel. A quick connecting mechanism which is in threaded connection with the high-strength bolt is inserted into the external corner end surface of the steel bracket; according to the quick connecting mechanism, the U-shaped elastic plate is pinched and pressed once to drive the inserting plates at the two ends to be synchronously inserted into the inserting frame, a plurality of high-strength bolts are locked at a time, the problem that the efficiency is low due to the fact that the bolts are installed one by one is solved, meanwhile, the anti-disengaging groove in the round block and the anti-disengaging assembly are automatically connected in a clamped mode to form mechanical self-locking, and the double effects of quick installation and automatic looseness prevention are achieved.

The present invention relates to a connecting rod type anti-tilting automatic rebound key switch; it comprises a sliding mechanism, a main body and an electric control mechanism, the main body is provided with an installation cavity, guide slide grooves are respectively provided at both ends of the installation cavity, the sliding mechanism comprises a sliding bracket and a connecting rod assembly, the sliding bracket is provided with a slider, the slider is clamped in the guide slide groove, so that the sliding bracket can be slidably arranged in the installation cavity of the main body, the connecting rod assembly is arranged at the bottom of the sliding bracket, the main body is provided with a push rod, and a reset spring is sleeved on the outer side of the push rod; the beneficial effects of the present invention are embodied as follows: by adopting the guide slide grooves at both ends of the main body and the sliders at both ends of the sliding bracket to form a sliding motion pair, the sliding bracket slides along the guide slide groove in the main body under the action of pressing force, and combined with the dual effects of the connecting rod assembly and the reset mechanism, the sliding bracket is provided with vertical thrust rebound reset after pressing is completed, the structure is simple, the defect of unilateral tilting of the traditional key switch is avoided, it is easy to use and has strong practicality.

The utility model discloses swimming goggles with an adjustable bandage, and relates to the field of swimming goggles. The glasses comprise a glasses main body and a binding band, a plurality of mounting holes are formed in the surface of the binding band, and an adsorption mechanism or a warning lamp is mounted on the inner side of each mounting hole; the suction mechanism comprises a suction cup, one side of the suction cup is clamped and fixed with a mounting hole in the binding band through a clamping block, the suction cup is combined with the T-shaped clamping block, the clamping block is vertically pressed into the mounting hole through elastic deformation of a rubber material of the binding band, stable clamping is formed, a negative pressure effect is generated when the suction cup makes contact with the swimming cap, and the suction cup is clamped and fixed with the mounting hole in the binding band. The adsorption force is formed on the smooth surface, meanwhile, the transverse fixing capacity is enhanced through a mechanical meshing structure of the clamping blocks and the mounting holes, the friction force between the bandage and the swimming cap is increased by 2.3 times through the dual effects, the positions of the suction cups are allowed to be adjusted at equal intervals along the bandage, it is ensured that users with different head circumferences can find the optimal adsorption points, and the sliding risk during strenuous exercise is avoided.

The application relates to a quick connecting node device of a modular assembly type building structure and belongs to the technical field of building connecting pieces. The quick connecting node device of the modular assembly type building structure comprises a steel bracket, both of the two female corner end faces of the steel bracket are provided with through holes, both of the two female corner end faces of the steel bracket are provided with high-strength bolts which are inserted into the through holes, and the male corner end face of the steel bracket is inserted with a quick connecting mechanism which is threadedly connected with the high-strength bolts. The quick connecting mechanism drives both end inserting plates to be synchronously inserted into an inserting frame through single-time pinching of a U-shaped elastic plate, and a plurality of high-strength bolts are locked at one time, so that the problem of low efficiency caused by installing the bolts one by one is solved. Meanwhile, the anti-disengagement groove on the circular block and the anti-disengagement assembly are automatically clamped to form mechanical self-locking, so that the dual effects of quick installation and automatic anti-loosening are realized.
