This utility model provides a clamping mechanism for internal hole sandblasting, comprising: a sandblasting box, the bottom of which is connected to a material receiving hopper, a shielding net fixedly connected to the upper end of the inner wall of the material receiving hopper, a control seat fixedly connected to the rear end of the inner wall of the sandblasting box, and a bearing seat fixedly connected to the bottom of the control seat; a driving unit, which is mounted on the control seat and the sandblasting box, and an assembly seat fixedly connected to the driving unit, with a sandblasting head mounted at the front end of the assembly seat; and a transmission unit, which is mounted inside the bearing seat and connected to the driving unit. This clamping mechanism for internal hole sandblasting, through the driving unit, controls the vertical movement of the sandblasting head, while simultaneously driving the fixed unit to rotate through the transmission unit, achieving uniform sandblasting of the workpiece's inner hole. During sandblasting, the sealing part dynamically seals the top of the workpiece's inner hole, reducing sand leakage and preventing equipment jamming and frequent shutdowns for cleaning.

This utility model discloses a rotatable Tai Chi coiling rod, belonging to the technical field of fitness equipment. Specifically, it includes a rotational damping mechanism and two coiling rod handles. The rotational damping mechanism comprises a metal connecting rod, a fixed sleeve, a torsion spring, a spacer sleeve, and sleeves. There are two fixed sleeves, each movably fitted onto both ends of the metal connecting rod. The torsion spring is fitted into the middle of the metal connecting rod, with its two ends hanging in the fixing grooves of the two fixed sleeves. The spacer sleeve is fitted into the middle of the torsion spring. There are two sleeves, each fitted onto the outer side of both ends of the torsion spring. This utility model uses a rotational damping mechanism as a carrier, utilizing two independently rotatable sleeves to connect the coiling rod handles to the fixed sleeves with torsion springs. This allows the handles at both ends of the coiling rod to achieve a damping rebound effect while maintaining rotatability, effectively preventing friction between the hand and the handles during training. This provides effective protection for the user's palms and enhances the training experience.

This invention discloses a self-powered intelligent insulator and its operation and control methods, belonging to the technical field of high-voltage power transmission equipment. The self-powered intelligent insulator includes a power generation mechanism, a monitoring mechanism, a cleaning mechanism, and a power management mechanism. The power generation mechanism is directly integrated into the insulator body and includes a composite nano-triboelectric generator for converting environmental mechanical energy, such as wind energy, raindrop energy, vibration energy, or any combination thereof, into electrical energy. The battery management mechanism is electrically connected to the power generation mechanism to receive and manage the electrical energy converted by the power generation mechanism. The monitoring mechanism is electrically connected to the power management mechanism to monitor the operating status of the insulator and output monitoring signals. The cleaning mechanism is electrically connected to the power management mechanism to perform anti-icing or decontamination operations based on the monitoring signals. This invention utilizes wind and raindrop energy in the environment to convert them into electrical energy, solving the problems of unstable sensor power supply under severe weather conditions and difficulties in maintaining the insulator surface against contamination and de-icing.

This application discloses an electrostatic removal device for substrates, belonging to the field of electrostatic removal devices for substrates. The device uses a detection module to monitor static electricity information in the area above the machine in real time, and a control module to precisely adjust the working state of the corresponding static electricity elimination module based on this information, achieving localized and on-demand elimination of static electricity. This not only significantly improves the efficiency and targeting of static electricity neutralization, avoiding the secondary contamination and frequent maintenance problems that may arise from the global effect of traditional ion fans, but also enhances adaptability to cleanroom environments, effectively ensuring process stability and product yield.

This invention provides a guide rail cleaning device for a spiral quick-freezing machine, comprising a fixing part and a wiping part disposed on the fixing part. The fixing part includes a placement plate, a fixing member, and a connecting member, both of which are connected to the placement plate. The wiping part is disposed on the placement plate, and the connecting member is connected to the wiping part, with the wiping part contacting the guide rail of the spiral quick-freezing machine. The connecting member includes at least two clamping plates that clamp the wiping part, which extends out of the clamping plates and contacts the guide rail. The fixing member is connected to the conveyor belt of the spiral quick-freezing machine, and as the conveyor belt moves, it drives the wiping part to clean the guide rail. Through the movement of the conveyor belt, the wiping part removes stains from the upper surface of the guide rail, ensuring the hygiene of the upper surface of the guide rail.

The utility model relates to a cloth bag mounting structure for cloth bag dust catcher, including the baffle, be provided with keel frame on the baffle, be provided with cloth bag on the keel frame, the fixed mounting of baffle is used for placing the mounting seat of keel frame and cloth bag, the compression tight member that is used for compressing tight cloth bag apron is slidably installed on the keel frame, the locking member that is used for locking compression tight member is rotatably installed on the keel frame.
