The utility model discloses a kind of turnover devices for circuit board zinc spraying, including base, it is characterized in that, still include: turnover table, the turnover table is set in the top of base, and the inside of the turnover table is provided with pivot, the two sides of the pivot are uniformly provided with clamp by second driving motor, and the inside of the clamp is uniformly clamped with circuit board body;Sucker, the top end in clamp inside is set to the sucker, annular air cavity, the edge in the inside of the sucker is set to annular air cavity, the bottom end of the sucker is provided with buffer layer, micro air pump, the micro air pump is all set to one end in the top of clamp.The utility model is equipped with base, turnover table, pivot, clamp, second driving motor, circuit board body, sucker, electromagnetic coil, annular air cavity, buffer layer and micro air pump, by the dual effect of magnetic force and negative pressure, can make circuit board body receive uniform clamping force, cooperate with elastic buffer layer, can effectively avoid circuit board deformation and produce scratch.

The application discloses a multifunctional physiotherapy bed, which comprises a bed plate, a bed frame, an electric control box, a stretching mechanism, a foot rocking device, a heating device, a vibrating device and a massaging device. The stretching mechanism comprises a traction part, a stretching belt, a thrust device and a foot clamping part. The traction part is arranged at the top end of the head part of the bed frame, the two ends of the stretching belt are wound around the traction part, the traction part is provided with the thrust device below the head part, and the tail part of the bed frame is provided with the foot clamping part. After two feet are placed on the foot clamping part, hands hold the stretching belt to drive the thrust device to slide. The multifunctional physiotherapy bed has the beneficial effects that: a user can independently control the size, angle and position of the traction force, freely controls and adjusts, drives the human body to stretch, so that the neck, spine and whole body joints under traction are pulled out of the gap, and a better stretching effect is achieved. In addition, the multifunctional physiotherapy bed is provided with the heating device, the vibrating device, a magnetotherapy device and the massaging device, the above functions can be used in combination and controlled in a single group, the physiotherapy bed has various functions, has wider adaptability and has more ideal effect.

The utility model discloses a transmission gearbox processing conveying device of emergency stop, clamping mechanism is fixedly connected with the connecting column below, the bottom fixed connection of connecting column has the sliding base, the sliding base is slidably arranged in the slide rail, the bottom fixed connection of sliding base has the electromagnet, the side fixed connection of connecting column has trigger subassembly, is provided with pressure sensor in trigger subassembly, is provided with control assembly in connecting column, through the force that holds trigger subassembly, makes pressure sensor obtain the extrusion of different degrees after signal transmission to control assembly analysis and control electromagnet to the slide rail generates the magnetic attraction of different size. Through the force that the worker holds trigger subassembly control electromagnet's magnetic force size, and then makes the slide rail to receive the magnetic attraction size and get the change, makes the equipment stop and position, this avoids the huge inertia force of equipment free sliding suddenly and stops down, optimizes the process of equipment shift, reduces the labor intensity of worker.
