Description

Technical Field

[0001] The utility model relates to the technical field of electric actuators, in particular to an electric actuator with anti-interference effect. Background Art

[0002] Electric actuators, also known as electric actuators, are mainly used to control valves. They constitute electric valves and are electromechanical products that use electricity instead of traditional manpower to control the rotation of valves to control the flow, direction, and flow of various types of fluids such as air, water, steam, various corrosive media, mud, oil, liquid metal, and radioactive media. Their function is to change the size of the controlled medium by receiving the control signal sent by the controller, thereby maintaining the controlled variable at the required value or within a certain range. In order to avoid the transmission signal being affected, an anti-interference device is usually installed when the electric actuator is used.

[0003] However, the anti-interference device is smaller than the actuator and is easily touched during operation, which can easily affect the normal operation of the anti-interference device, thereby reducing the anti-interference effect and easily causing damage to the anti-interference device. Utility Model Content

[0004] The purpose of the present utility model is to provide an electric actuator with anti-interference effect to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] An electric actuator with anti-interference effect comprises an electric actuator body, wherein the electric actuator body comprises a shell, a connecting piece is fixedly mounted on the bottom end of the shell, and an anti-interference box is arranged on the right side of the shell.

[0007] The anti-interference box includes a lower plate body, an upper plate body is arranged above the lower plate body, and the lower plate body and the upper plate body are both fixedly installed at the upper and lower ends of the right side of the shell.

[0008] A further improvement of the technical solution of the present utility model is that a left protective cover is rotatably installed at the left inner end of the upper plate body and the lower plate body, a fixed block is fixedly installed on the outer surface of the left protective cover, and a right protective cover is rotatably installed at the right inner end of the upper plate body and the lower plate body. The setting of the left protective cover and the right protective cover can protect against interference devices, prevent them from external impact, and promote work safety.

[0009] A further improvement of the technical solution of the present utility model is that a snap plate is rotatably installed on the outer surface of the right protective cover, the other end of the snap plate is movably sleeved on the outer surface of the fixed block, and an anti-interference device is detachably installed on the top of the lower plate body. The snap plate is engaged with the outer surface of the fixed block, which can fix the closure of the left and right protective covers.

[0010] A further improvement of the technical solution of the present utility model is that: sliding grooves are opened on both sides of the top of the lower plate body, a rotating gear is rotatably connected to the middle position of the bottom end of the lower plate body, and a handle is fixedly connected to the middle position of the bottom end of the rotating gear, and the sliding grooves can limit the moving clamping plate.

[0011] A further improvement of the technical solution of the present utility model is that: the teeth on both sides of the rotating gear are meshed with brake tooth plates, and a clamping plate is fixedly installed on the top of one end of the brake tooth plate. The clamping plate passes through the slide groove and extends on both sides of the top of the lower plate body. The two groups of clamping plates are fit and squeezed on both sides of the anti-interference device, which can promote stable operation and thus improve the anti-interference effect.

[0012] A further improvement of the technical solution of the present utility model is that a sleeve is fixedly mounted on the bottom end of the lower plate body located on the right side of the rotating gear, and a piston rod is movably inserted into the other end of the sleeve.

[0013] A further improvement of the technical solution of the present utility model is that: a positioning block is fixedly installed on the other end of the piston rod, and the positioning block is movably inserted into the right tooth groove of the rotating gear. A return spring is movably sleeved on the outer surface of the piston rod, and the positioning block is abutted against the gear groove of the rotating gear under the elastic pushing force of the return spring, which is convenient for fixing the rotating gear and preventing it from rotating.

[0014] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0015] The utility model provides an electric actuator with anti-interference effect. A handle is arranged to rotate to drive a rotating gear to rotate. The rotation of the rotating gear is utilized to cause the brake tooth plates on both sides to move relative to each other. During the movement, the clamping plates on both sides are driven to move relative to each other until they are clamped on the outer surfaces of both sides of the anti-interference device, clamping and fixing it to make its operation stable, thereby further improving the working efficiency of the anti-interference device.

[0016] The utility model provides an electric actuator with anti-interference effect. By arranging the left protective cover and the right protective cover to be relatively closed, protection is formed against interference devices, which can prevent the electric actuator from being impacted by the outside world, ensure its safe use, further achieve protection against interference devices, and improve its anti-interference effect.

[0025] Furthermore, by the relative closure of the left protective cover 33 and the right protective cover 35, protection is formed against the interference device 37 to prevent it from being impacted by the outside world. The buckle plate 36 is sleeved on the outer surface of the fixing block 34 to fix the closure of the left protective cover 33 and the right protective cover 35. Example

[0026] like Figure 1-5 When the cam 314 is in the unlocking state, the locking plate 313 is locked and the locking plate 314 is locked.

[0027] Furthermore, the electric actuator body 1 can avoid interference from other signals when in use through the setting of the anti-interference device 37, which is conducive to better use. In order to ensure its safety when in use, the anti-interference device 37 is placed on the top of the lower plate 31, and the handle 313 is rotated to drive the rotating gear 312 to rotate. The rotation of the rotating gear 312 is used to promote the relative movement of the braking tooth plates 314 on both sides.

The positioning block 318 drives the piston rod 317 to rebound and engage in the tooth groove under the elastic potential energy of the return spring 319, which is convenient for fixing the rotating gear 312 to prevent self-rotation. Then, by relatively closing the left protective cover 33 and the right protective cover 35, protection is formed against the interference device 37 to prevent it from being hit by the outside.
