[0002] An electric actuator is a drive device that can provide linear or rotary motion. It uses a certain driving energy source and works under a certain control signal. The actuator uses liquid, gas, electricity or other energy and converts it into a driving action through a motor, cylinder or other device. It is mostly used in some high-pressure and large-diameter valves.

[0003] After searching, the patent with announcement number CN215891315U discloses a multi-rotation electric actuator, which relates to the field of electric actuators. In order to solve the problem that the heat dissipation effect of the current electric actuator is poor, especially when used in hot weather, the motor on the actuator will generate a lot of heat. Once the motor cannot be effectively dissipated, it will cause the motor to be damaged, thereby affecting the normal service life of the electric actuator. The outer surface of the actuator body is fixedly connected with the actuator motor, the outer surface of the actuator motor is provided with a heat dissipation cylinder, the top of the heat dissipation cylinder is fixedly connected with a liquid storage tank, the interior of the liquid storage tank is provided with a small submersible pump and condensate, the output end of the small submersible pump is fixedly connected with a liquid inlet pipe, the interior of the heat dissipation cylinder is provided with a liquid storage cavity, the inner wall of the heat dissipation cylinder is fixedly connected with a heat conductive ring sheet, the inner wall of the heat dissipation cylinder is fixedly connected with a fixing frame, and the inner wall of the fixing frame is fixedly connected with a fan motor.

[0004] The technical solution has the following problems:

[0005] Although the heat sink can be fixed by multiple fastening bolts, when the actuator motor is maintained, tools are required to unscrew multiple bolts one by one for maintenance, which is troublesome and inefficient. Utility Model Content

[0006] The purpose of the utility model is to solve the problem in the prior art that although the heat sink can be fixed by multiple fastening bolts, when the actuator motor is maintained, tools are needed to unscrew multiple bolts in sequence for maintenance, which is troublesome and inefficient. A multi-rotation electric actuator is proposed to solve the problem.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A multi-rotation electric actuator comprises an actuator body and an actuator motor, wherein the actuator motor is fixedly arranged on one side of the actuator body, a frame is fixedly arranged on one side of the actuator body, a cylinder is arranged on one side of the frame, mounting plates are fixedly arranged on both sides of the cylinder, a slot matching the cylinder and the mounting plate is opened on one side of the frame, the cylinder and the mounting plate are plugged into the slot, ventilation holes are opened on both sides of the cylinder, and a blowing fan for cooling the actuator motor is fixedly arranged on the inner wall of one of the ventilation holes;

[0009] The fixing mechanism is arranged on the frame and is used to fix the cylinder.

[0010] In a possible design, the fixing mechanism includes a frame, two special-shaped frames, two springs, two short plates and two insertion rods. The inner walls on both sides of the frame are respectively slidably connected to the two sides of the frame, one side of the two special-shaped frames is respectively fixedly connected to the two sides of the frame, the sides of the two short plates close to each other are respectively fixedly connected to the two sides of the frame, the top ends of the two springs are respectively fixedly connected to the bottoms of the two short plates, the bottom ends of the springs are connected to the bottom inner walls of the special-shaped frames, the top ends of the two insertion rods are respectively fixedly connected to the bottoms of the two special-shaped frames, and through holes are opened on the two mounting plates, and the insertion rods are inserted into the through holes.

[0011] In a possible design, filter screens for dust prevention are fixed to both sides of the cylinder by screws, and the filter screens cover the ventilation holes.

[0012] In a possible design, both sides of the frame are provided with slide grooves, and both inner walls of the frame are fixedly provided with sliders, and one side of the slider is slidably connected to the inner wall of the slide groove.

[0013] In a possible design, a handle is fixedly provided on the top of the frame for facilitating pulling the frame to move.

[0014] In a possible design, the filter is made of a HEPA filter.

[0015] In the present application, when in use, the blowing fan is started, and the starting of the blowing fan generates blowing air to dissipate heat for the actuator motor. The provided filter can intercept dust and debris in the air to prevent them from entering the cylinder. When the actuator motor needs to be maintained, the handle is held with one hand and then pulled upward. The movement of the handle drives the movement of the frame, the movement of the frame drives the movement of the special-shaped frame, and the movement of the special-shaped frame drives the movement of the insertion rod. At this time, the spring is compressed to cause the insertion rod to leave the through hole of the mounting plate on the cylinder. Then, the cylinder is pulled outward with one hand to cause the cylinder mounting plate to leave the slot of the frame, so that the cylinder can be disassembled without the need to take tools to disassemble multiple bolts. It is more convenient and improves efficiency. Then you can maintain the actuator motor. After maintenance, when installing the cylinder, hold the handle with one hand and pull it up. The movement of the handle drives the movement of the frame, the movement of the frame drives the movement of the special-shaped frame, and the movement of the special-shaped frame drives the movement of the plug rod. At this time, the spring is compressed, and the cylinder and the mounting plate are inserted into the slot. Release the handle, and the force of the spring is released. The thrust of the spring pushes the frame, the special-shaped frame and the plug rod to move, so that the plug rod is inserted into the through hole of the mounting plate to complete the fixation of the cylinder. The material of the filter is HEPA filter, which has good filtering effect. Of course, other materials can also be selected.

[0016] The beneficial effects of the present invention are:

[0017] In the utility model, the multi-rotation electric actuator is fixed by a fixing mechanism. One hand holds the handle and then pulls it upward. The movement of the handle drives the movement of the frame. The movement of the frame drives the movement of the special-shaped frame. The movement of the special-shaped frame drives the movement of the insertion rod. At this time, the spring is compressed to make the insertion rod leave the through hole of the mounting plate on the cylinder. Then, one hand pulls the cylinder outward to make the cylinder mounting plate leave the slot of the frame. Thus, the cylinder can be disassembled, and there is no need to take tools to disassemble multiple bolts. It is more convenient and improves efficiency.

[0018] In the utility model, the cylinder body can be disassembled through the fixing mechanism, so there is no need to take tools to disassemble multiple bolts, which is more convenient and improves efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
