The application discloses a socket panel waterproof structure, a protection door module and a waterproof socket, and belongs to the technical field of socket waterproofing. The panel waterproof structure comprises at least a waterproof ring which forms a continuous annular protrusion around one socket hole, the root of the waterproof ring is fixed to the end face of the socket, the free end of the waterproof ring protrudes from the end face of the socket and has a radial dimension greater than that of the root, when the end face of the plug abuts against the free end, the waterproof ring generates radial elastic deformation with the root as the fixed end, so that the end face of the free end abuts against the end face of the plug to form a seal around the corresponding socket hole; the protection door module comprises a protection door cover, the outer end face of the protection door cover is provided with the waterproof ring and is provided with a mounting groove in which a first waterproof layer and a second waterproof layer are embedded; the waterproof socket comprises a shell, a base and the protection door module. The waterproof socket is compatible with the plug without the pin insulation sheath, and the waterproof grade and the electrical safety performance of the socket are significantly improved through the cooperation of the single-hole independent waterproof ring and the multi-stage internal waterproof layer.

This utility model discloses an easily assembled inductive displacement sensor, relating to the field of inductive displacement sensor technology. The utility model includes a sensor body with multiple sets of mounting components. These mounting components are configured to install the sensor body in a designated position. Each mounting component includes an elastic plate with two clamping plates fixedly mounted on its two sides. The sensor body has multiple slots embedded along its length for engaging the clamping plates and the elastic plate. The elastic plate is elastic and has multiple limiting teeth fixedly mounted on the ends of the two clamping plates opposite to the elastic plate. The slots contain multiple limiting grooves that extend along the circumference of the limiting teeth. This utility model, through the cooperation of the mounting components and the slots, stably mounts the sensor body onto the mounting plate, completing the assembly. The overall structure features simple installation steps, high installation efficiency, strong connection stability, good installation flexibility, and easy disassembly and maintenance.

This application provides a high-efficiency sealing pipe connection structure, comprising a connection mechanism and a pipe assembly. The inner wall of the connection mechanism has a stepped flow guiding cavity, which includes a contraction section and an expansion section. The inner wall of the contraction section has a turbulence-inducing protrusion. It also includes a convex-shaped turbulent elastic sealing mechanism, whose inner wide sealing end face conforms to the outer wall of the pipe and is machined with spiral microgrooves. The inner wall of the connection mechanism has a flow guiding groove, one end of which connects to the expansion section, and the other end extends to the starting end of the spiral microgrooves. This relates to the field of fluid transport technology. The fluid is pressurized by the contraction section, and the turbulence-inducing protrusions create a rotating turbulent flow. Part of the turbulence is guided to the sealing mechanism through the flow guiding groove, using fluid pressure to enhance the sealing fit. Simultaneously, the fluid generates circumferential scouring along the spiral microgrooves, achieving self-cleaning of the sealing surface. This invention has a compact structure, reliable sealing, and self-cleaning capability, and is suitable for rapid pipe connections in high-pressure, impurity-containing fluid environments.

This utility model relates to the field of machining equipment technology, specifically a dustproof water-cooling device for presses. It includes a fixed frame with a deformable integrated cooling sealing plate at its bottom. Several sets of adjustable clamping units, composed of threaded columns and threaded cylinder pressure blocks, are located on the back side of the integrated cooling sealing plate on the fixed frame. These units apply pressure points in different directions to the integrated cooling sealing plate, adjusting its deformation posture. Side plates are provided on both sides of the fixed frame, and elastic limiting mechanisms are connected between the two ends of the integrated cooling sealing plate and the side plates. These elastic limiting mechanisms include a retaining ring, a guide shaft, and a tension spring. This dustproof water-cooling device can flexibly adapt to press surfaces of different shapes, improving the fit and enhancing cooling efficiency and dustproof sealing performance. It also features a simple structure and high practicality.

This utility model provides a corrosion-resistant valve sealing sleeve, belonging to the technical field of sealing connection components. It includes a circular tube with a mounting plate A fixedly connected to its outer wall and a sealing ring A fixedly connected to its inner wall. It also includes a limiting assembly comprising a guide rod symmetrically fixedly connected to the top wall of the mounting plate A, a lifting plate slidably connected to the outer wall of the guide rod, a strong spring sleeved on the outer wall of the guide rod, a handle fixedly connected to the top wall of the lifting plate, and a locking plate fixedly connected to the bottom wall of the lifting plate. In this utility model, the sealing assembly, through the complex cooperation of the embedded block, the anti-reverse groove, and the sealing sleeve body, increases the sealing contact area and the tightness of the fit. Corrosive media can only flow out through the Z-shaped anti-reverse groove, and its tortuous path increases the resistance to media penetration, resulting in a stronger barrier effect against corrosive media and a lower risk of leakage.
