The application provides a wheel speed sensor which can be quickly disassembled, relates to a wheel speed sensor, and comprises a sensor shell, a sensing end head arranged at one end inside the sensor shell, a cable shell connecting seat arranged at the other side inside the sensor shell, a fastening bolt and a shell connecting seat fixed to the surface of the sensor shell, and one side of the shell connecting seat is fixedly connected with a connecting mechanism matched with the fastening bolt. Through the connecting mechanism, after the fastening bolt rotates several rounds to remove the interference with the connecting disc, the interference of the upper interference mechanism with the driving component is removed, the buckle cannot form the limiting of the connecting disc, the connecting disc and the sensor shell connected therewith can be taken out through the arc-shaped groove thereon, the quick disassembly of the sensing component is realized, the fastening bolt is not disassembled at this time, the subsequent quick assembly of the sensor shell and the sensing component thereon is more convenient, and the problem that the wheel speed sensor is inconvenient to disassemble in the prior art is solved.

This invention relates to the field of dental medical devices and discloses a dental ultrasonic bone scalpel working tip limiting wrench, comprising a wrench locking block, a wrench tightening block, a rubber pad, a tightening screw, and a rotating assembly. When it is necessary to install or remove the working tip, the operator aligns the wrench slot with and fits it onto the wrench part of the bone scalpel working tip. At this time, the clamping slot on the rubber pad is inserted into the working tip. Due to the elasticity of the rubber pad, its clamping slot expands elastically during insertion and generates a radial contraction clamping force, thereby stably and elastically clamping the working tip inside the wrench and preventing the working tip from falling off freely. When the working tip is completely removed from the handle, due to the continuous action of the elastic clamping force of the rubber pad, the working tip is held inside the wrench and will not accidentally slip to the ground or hard surface due to gravity, thereby effectively avoiding deformation or damage to the working tip caused by falling.

This invention discloses an opening and closing mold device for a ground-rail type refrigerator door foaming production line, relating to the technical field of refrigerator door production equipment. It includes a fixing mechanism and an opening and closing mechanism. The fixing mechanism includes a foaming mold frame mounted on the top of a transfer trolley. The foaming mold frame includes a lower mold frame and an upper mold frame hinged together. The lower mold frame is fixed to the transfer trolley, and a hook is fixedly installed on the side wall of the upper mold frame. A locking hook is provided below the hook, and the middle section of the locking hook is rotatably mounted on the lower mold frame. Both the top end of the locking hook and the bottom end of the hook are hook-shaped. A second elastic telescopic rod is provided on the transfer trolley for resetting the locking hook. This opening and closing mold device for a ground-rail type refrigerator door foaming production line achieves collision-free engagement of the foaming mold frame through a cooperative structure of bent plates, bent strips, connecting frames, and rollers. It also provides guidance and limits for the opening of the upper mold frame, preventing free fall or rigid impact closure, protecting the foaming mold, and improving production efficiency.

The utility model discloses an anti-falling safety fixer, which comprises a U-shaped fixing clamp, a U-shaped fork head, a connecting arm, a first limiting piece and a second limiting piece, the U-shaped fixing clamp is used for being installed on a cross beam of a bed frame, the U-shaped fork head is used for supporting a guardrail of the bed frame, the connecting arm is rotatably connected with the U-shaped fixing clamp and the U-shaped fork head, and the first limiting piece is used for limiting the U-shaped fork head. The first limiting piece is used for limiting relative rotation of the connecting arm and the U-shaped fixing clamp, the second limiting piece is used for limiting relative rotation of the connecting arm and the U-shaped fork head, and the connecting arm is provided with a microswitch, a controller and a buzzer alarm; when the U-shaped fork head rotates to touch the microswitch, the microswitch sends a signal to the controller, and the controller controls the buzzer alarm to buzz to give an alarm. The bed guardrail is novel in structure, reliable in supporting, convenient to adjust and use and intelligent in early warning, and medical staff can conveniently and timely prevent a patient from falling down from the bed or climbing over the guardrail to fall down from the bed.
