Description

Technical Field

[0001] This utility model relates to the field of electric actuator technology, and in particular to a multi-turn electric actuator. Background Technology

[0002] An electric actuator is a drive device that provides linear or rotary motion. It utilizes some kind of driving energy and operates under the action of a control signal. Actuators use liquid, gas, electricity, or other energy sources and convert them into driving force through a motor, cylinder, or other device. There are three basic types: partial-turn, multi-turn, and linear-stroke. Basic actuators are used to drive valves to the fully open or fully closed position, while actuators used to control valves can precisely move the valve to any position.

[0003] A search revealed a multi-turn electric actuator (publication number: CN214404871U), comprising an actuator body and a mounting box. The mounting box is mounted on the actuator and contains a heat dissipation mechanism, which includes a horizontal plate and a vertical plate. The mounting box has a first mounting groove and a second mounting groove. The vertical plate and the horizontal plate are respectively connected to a first mounting block and a second mounting block. The outer walls of the first and second mounting blocks abut against the inner walls of the first and second mounting grooves. Heat dissipation pipes are mounted on the vertical plate, and each pipe has corrugated heat dissipation blocks. Heat dissipation fins are connected between the pipes. An exhaust fan is mounted on the mounting box. Vent holes are provided near the exhaust fan on the heat dissipation pipes, and heat-conducting rods are inserted between the vent holes. Exhaust holes are provided away from the exhaust fan on the heat dissipation pipes. This invention, by incorporating a heat dissipation mechanism, can quickly and effectively absorb and dissipate the heat generated during operation of the electric actuator, thus extending its service life.

[0004] While the above solution can quickly and effectively absorb and dissipate the heat generated during operation of the electric actuator, thus extending the service life of the electric actuator, it requires the removal of multiple screws during disassembly, making disassembly inconvenient. Furthermore, the removal of moisture from the air is necessary to dissipate the heat from the electric actuator, in order to avoid damaging the internal parts of the electric actuator. Utility Model Content

[0005] The main purpose of this utility model is to provide a multi-turn electric actuator. By setting up a disassembly unit, it solves the problem that multiple screws need to be removed during disassembly, which makes disassembly inconvenient. By setting up a heat dissipation unit, it solves the problem of heat dissipation of the electric actuator and removal of moisture from the air to avoid damage to the internal parts of the electric actuator.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A multi-turn electric actuator includes a base, a linkage unit disposed at the top of the base, a disassembly unit disposed at the bottom of the base, and a heat dissipation unit disposed on one side of the base.

[0008] The linkage unit includes a connecting seat fixedly connected to the top of the base, and an adjustment component fixedly connected to the top of the connecting seat;

[0009] The disassembly unit includes a base plate disposed at the bottom end of the base and a snap-fit ​​assembly disposed at the top end of the base plate;

[0010] The heat dissipation unit includes multiple fixed posts disposed on one side of the base, a connecting ring fixedly connected to the middle of the fixed posts, a filter assembly disposed inside the connecting ring, and a moisture-proof assembly disposed inside the housing of the fixed posts.

[0011] Preferably, the linkage unit includes an actuator disposed at the top of the connecting seat in the adjustment assembly, an emergency turn handle fixedly connected to one side of the actuator, and a rotary handle disposed on the other side of the actuator.

[0012] Preferably, the snap-fit ​​assembly in the disassembly unit includes two plug-in plates fixedly connected to the top of the base plate and extending into the interior of the base housing, and a plurality of rectangular holes opened inside the plug-in plates.

[0013] Preferably, the snap-fit ​​assembly in the disassembly unit further includes multiple insertion holes on the front and rear sides of the base and corresponding to the rectangular holes, insertion blocks disposed inside the insertion holes, a limiting plate fixedly connected to one side of the multiple insertion blocks, a vertical groove disposed inside the insertion blocks, an elastic post disposed at the top of the vertical groove, a spring disposed on the surface of the elastic post, and a limiting post fixedly connected to the bottom of the elastic post.

[0014] Preferably, the length of the plug block in the disassembly unit is greater than the thickness of the base shell.

[0015] Preferably, the filter assembly in the heat dissipation unit includes multiple heat dissipation holes opened inside the housing of the connecting ring, a fixing frame disposed inside the heat dissipation holes, and a filter screen disposed inside the fixing frame.

[0016] Preferably, the snap-fit ​​component in the heat dissipation unit includes multiple vent holes opened in the middle of the fixed post, moisture-proof paper fixedly connected to the front and rear sides of the vent holes, and through holes arranged crosswise inside the two moisture-proof papers.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] I. In this utility model, by setting up a disassembly unit, when it is necessary to disassemble the electric actuator, the two limit plates can be pulled first. Since the bottom end of the limit post is arc-shaped, the limit post will squeeze the elastic post and spring upward under the action of the pulling force. Then the side of the limit post will no longer contact the inner side of the base shell. Continue to pull the limit plates to pull the plug block out from the corresponding rectangular hole and plug hole. Then pull the base upward to separate the base plate from the base. In this way, the electric actuator can be disassembled without a screwdriver, which improves the convenience of disassembly.

[0019] Second, in this utility model, through the setting of the heat dissipation unit, the large amount of heat generated by the electric actuator during operation will be discharged through the fixed column and connecting ring. At the same time, outside air enters through the heat dissipation holes and the ventilation holes. Moisture and impurities in the outside air need to be filtered out. Impurities are blocked by the filter screen, while moisture is absorbed by two moisture-proof papers. The multiple cross-shaped through holes improve the absorption rate of moisture in the air, thus improving the service life of the internal parts of the electric actuator.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example

[0036] The linkage unit 2 includes an actuator 202 located at the top of the connector 201 in the adjustment assembly, an emergency turn handle 203 fixedly connected to one side of the actuator 202, and a rotary handle 204 located on the other side of the actuator 202.

[0037] The snap-fit ​​assembly in the disassembly unit 3 includes two plug-in plates 303 fixedly connected to the top of the base plate 301 and extending into the housing of the base 1, and a plurality of rectangular holes 304 opened inside the plug-in plates 303.

[0042] When it is necessary to disassemble the electric actuator, the two limit plates 302 can be pulled first. Since the bottom end of the limit post 309 is arc-shaped, the limit post 309 will press the elastic post 307 and spring 306 upward under the action of the pulling force. Then the side of the limit post 309 will no longer contact the inner side of the outer shell of the base 1. Continue to pull the limit plate 302 to pull the plug block 305 out from the corresponding rectangular hole 304 and plug hole. Then pull the base 1 upward to separate the base plate 301 from the base 1. In this way, the electric actuator can be disassembled without a screwdriver, which improves the convenience of disassembly. Example

At the same time, outside air enters through the heat dissipation hole 403 and the vent hole 407. Moisture and impurities in the outside air need to be filtered out. Impurities are blocked by the filter screen 404, while moisture is absorbed by the two moisture-proof papers 405.
