A mounting base is provided at the lower part of the high-frequency transformer body. Several vertical support columns are provided on the upper part of the mounting base, located on multiple sides of the high-frequency transformer body. Several anti-collision plates are provided on the upper part of the mounting base, located on multiple sides of the high-frequency transformer body. A shock absorber with a damping effect is provided between the vertical support columns and the anti-collision plates. An arc-shaped first edge protection plate is provided between the sides of two adjacent anti-collision plates. The first edge protection plate is elastic. A fixing connecting plate for connection and installation is provided at the lower part of the vertical support columns. In this utility model, several anti-collision plates and several first edge protection plates provide an impact-resistant effect on multiple sides of the high-frequency transformer body, improving the impact resistance and impact-resistant area of ​​the high-frequency transformer body.

The utility model relates to the related technical field of flexible display screens, in particular to a supporting piece for a flexible display screen, which comprises a supporting pad, a protective pad, an adsorption pad and a supporting assembly, the protective pad is connected to the fixed position of the supporting pad, and the adsorption pad is arranged at the clamping position of the protective pad. A user manually presses the protective pad and the supporting pad, the attaching cover and the corrugated cover are in a sealed state, the attaching cover and the corrugated cover can be firmly adsorbed to the bottom end of the flexible display screen through air adsorption force, meanwhile, the bottom end of the flexible display screen is subjected to air supporting, and the flexible display screen can be bent synchronously with supporting pieces adopted by the flexible display screen; in addition, the whole flexible display screen can be supported through folding deformation of the attaching cover and the corrugated cover, the supporting height of the flexible display screen is increased, after the flexible display screen is flatly laid, compression-resistant supporting is conducted through the attaching cover and the corrugated cover, and the bottoms of the attaching cover and the corrugated cover are folded and adsorbed to form air supporting.

This utility model provides a linear motor positioning device, relating to the field of linear motor technology, to solve the problems of existing linear motor positioning devices, which typically use anti-collision posts. These posts require replacement after prolonged use, and their cushioning and anti-collision effect deteriorates with use. The new device includes: slide rails fixedly mounted on both sides of the top of the main body; a magnetic rail positioned in the middle of the top of the main body; anti-collision posts on the main body; a coil inside the driving component; the driving component slidingly mounted on the slide rails; and magnetic posts on both sides of the driving component. When the driving component moves, if a magnetic post approaches an anti-collision post, the opposing surfaces of the anti-collision post and the magnetic post are made of the same pole. Due to the principle of like poles repelling each other, direct contact between the magnetic post and the anti-collision post is avoided, achieving an anti-collision effect. This replaces traditional anti-collision posts made of rubber or other materials, eliminates the need for periodic replacement, and provides greater stability during operation.

The application relates to the field of oil-immersed devices, and discloses an explosion-proof device of an explosion-proof membrane of an oil-immersed equipment lifting seat. In the application, the explosion-proof oil tank serves as an oil storage component, the bottom surface of the explosion-proof oil tank is connected with a supporting insertion rod, a connecting socket and a ceramic bearing table serving as an assembly with insulation properties, the bottom of the supporting insertion rod, the connecting socket and the ceramic bearing table serving as a supporting assembly is connected with a metal base and a metal strip frame to form a metal cage assembly as a whole, and a grounding assembly is formed by a metal floor, a grounding insertion rod, a grounding sleeve, a grounding wire and a grounding base, so as to form a protective assembly similar to a Faraday cage in cooperation with the cage assembly, so that the explosion-proof oil tank in the interior can still keep the electric potential stable under the condition of a relatively large surrounding charged environment or electric shock, the possibility of explosion in the explosion-proof oil tank is avoided, and the cage assembly also plays a protective role to avoid the collision of the explosion-proof oil tank.

The utility model discloses an anti-collision safety guardrail for a coke oven maintenance platform. The anti-collision safety guardrail comprises a lifting guardrail assembly and an anti-collision assembly, the anti-collision assembly comprises a laser range finder arranged on the maintenance platform, a displacement sensor arranged on the lifting type guardrail assembly, a PLC and an alarm. The signal output ends of the laser range finder and the displacement sensor are both in signal connection with the signal input end of the PLC, and the signal output end of the PLC is respectively in signal connection with the signal input ends of the alarm and the driving device of the coke pusher. The coke pusher maintenance platform has the advantages that the distance between the coke pusher and the maintenance platform and the lifting state of the guardrail are detected through the laser range finder and the displacement sensor respectively, and when the states of the coke pusher and the guardrail are not matched, the PLC triggers the alarm to give an alarm in time to remind workers to check and control starting and stopping of the coke pusher, so that safety accidents are avoided, and meanwhile the safety of the coke pusher is guaranteed. And the safety guardrail is prevented from being damaged due to collision with the coke pusher.
