Technical Field

[0001] The utility model belongs to the technical field of actuators, and particularly relates to a portable connection structure for an actuator. Background Art

[0002] An actuator is an essential component in an automatic control system. Its function is to receive signals from a controller, change the flow rate of a controlled medium, and maintain the controlled variable at a required value or within a certain range.

[0003] For example, a Chinese patent document discloses an electric actuator for regulating a gate [Application No.: 202410316688.8; Publication No.: CN117967855A]. It includes a valve mechanism. A main control connecting rod passes through the upper part of the valve mechanism. An electric actuator housing is inserted into the main control connecting rod. A support frame is fixedly connected to the main control connecting rod. A cover plate is provided on the upper part of the electric actuator housing, and an anti-collision protection layer is laid on the cover plate. It also includes a clamping unit. The clamping unit includes a clamping opening formed on the inner wall of the electric actuator housing. A clamping member is clamped in the clamping opening. An actuator fixing frame is fixedly connected to the lower part of the clamping member.

[0004] The above-mentioned electric actuator for regulating a gate is convenient for the loading and unloading of the electric actuator housing, the cover plate, and the actuator fixing frame through the clamping unit. However, the main control connecting rod passes through the upper part of the valve mechanism, and the main control connecting rod is inserted into the electric actuator housing. Currently, in order to firmly connect the main control connecting rod and the electric actuator housing, screws are used to pass through the two to fix them together. In this way, the loading and unloading of the valve mechanism and the electric actuator housing are not convenient enough. Summary of the Invention

[0005] The purpose of the utility model is to provide a portable connection structure for an actuator with a simple structure and convenient loading and unloading in view of the above problems existing in the prior art.

[0019] The following are specific embodiments of the present invention in combination with the drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0020] Such as Figure 1 、 Figure 2 and Figure 3As shown in the figure, the portable connection structure of this actuator includes a valve body 1 and a housing 2. The top of the valve body 1 has a connecting portion 3 that protrudes outward upward. The connecting portion 3 is inserted into the housing 2, and a pin 4 is arranged through the connecting portion 3 and the housing 2. The pin 4 has a bent section 41, and the connecting portion 3 or the housing 2 has a limiting portion for limiting the bent section 41.

[0021] When the portable connection structure of this actuator is used, first insert the connecting portion 3 into the housing 2, and then insert the pin 4 through the connecting portion 3 and the housing 2 until the bent section 41 is limited by the limiting portion. In this way, the connection between the valve body 1 and the housing 2 is completed, and the operation is convenient; because the bent section 41 has its own elasticity, the bent section 41 has a tendency to be limited by the limiting portion. During the use process, the pin 4 will not fall off, and the working stability is good; when disassembly is required, apply force to pull out the pin 4, and the pulling force overcomes the elasticity of the bent section 41 itself, and the pin 4 can be smoothly pulled out. At this time, the valve body 1 and the housing 2 can be separated, and the disassembly is convenient.

[0022] The pin 4 is in a U shape, and both ends of the pin 4 are arranged through the connecting portion 3 and the housing 2. In this way, there are more connection points, and the structure after the connection of the connecting portion 3 and the housing 2 is stable, and the use stability is good.

[0023] The limiting portion is a limiting block 5 at the bottom of the housing 2. Both side portions of the limiting block 5 have limiting grooves 51. Both sections of the pin body of the pin 4 have bent sections 41 that bend inward and are limited in the corresponding limiting grooves 51. In this way, the structure is simple, and the two bent sections 41 are limited in the corresponding limiting grooves 51, and the connection stability is good. Both side edges of the limiting block 5 have rounded corners 52, and the rounded corners 52 play a guiding role to facilitate the insertion of the bent section 41 into the limiting groove 51.

[0024] A limiting component for circumferential limiting between the connecting portion 3 and the housing 2 is provided. In this way, after the connecting portion 3 and the housing 2 are inserted, they cannot rotate circumferentially, the structural strength is high, and it is also convenient for the pin 4 to pass through.

[0025] The connecting portion 3 is inserted into the housing 2. The limiting component includes a plurality of outwardly protruding limiting ribs 31 on the outer wall of the connecting portion 3, and the inner wall of the housing 2 has limiting grooves for the corresponding limiting ribs 31 to be embedded. In this way, the circumferential limiting between the connecting portion 3 and the housing 2 is realized. In this embodiment, the number of the limiting ribs 31 is four and they are circumferentially distributed on the outer wall of the connecting portion 3.

[0026] The outer wall of the connecting portion 3 has an annular groove 32, and the pin body of the pin 4 passes through the annular groove 32. In this way, the processing is convenient, the pin body of the pin 4 is resisted by the upper and lower groove walls of the annular groove 32, and the connection stability between the pin 4 and the connecting portion 3 is good. The outer wall of the housing 2 has an extended portion 21 that extends outward and through which the pin 4 passes. The extended portion 21 increases the contact area between the housing 2 and the pin 4, increases the structural strength, and extends the service life.

[0027] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art. The specific embodiments described herein are merely illustrative of the spirit of the present utility model. Those skilled in the art to which the present utility model pertains may make various modifications or supplements to the described specific embodiments or use similar ways for substitution, but will not deviate from the spirit of the present utility model or exceed the scope defined by the appended claims.
