Detailed Description
The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.
As shown in fig. 1 to 3, the connection device for an electric actuator according to the present embodiment includes a main body 1, and connection pipes 2 are provided at two ends of the main body 1. Connecting device includes sealing washer 3, gasket 4, holding ring 5 and retaining member 6, 3 tip of sealing washer are equipped with inclined plane 31, and sealing washer 3 sets up in connecting pipe 2, and the fitting surface 21 in inclined plane 31 and the connecting pipe 2 supports and leans on. The gasket 4 is arranged in the connecting pipe 2 and abuts against the sealing ring 3, the positioning ring 5 is provided with an annular convex part 51 and an opening part 52, and the annular convex part 51 is positioned at one end of the positioning ring 5 and abuts against the gasket 4. The locking member 6 comprises an external thread 61 and an internal inclined surface 62, the external thread 61 is arranged corresponding to the internal thread 22 of the connecting pipe 2, and the internal inclined surface 62 is abutted against the positioning ring 5. Among the above-mentioned technical scheme, when pipeline 7 is connected with electric actuator's main part 1 through connecting device, the pipeline inserts in connecting pipe 2 and wears to establish in sealing washer 3, gasket 4, holding ring 5 and retaining member 6, then rotates retaining member 6, makes retaining member 6 remove to the sealing washer direction through threaded connection. Since the inner slope 62 abuts against the positioning ring 5, the inner slope 62 presses the positioning ring 5 to contract, clamping the pipe 7 by the positioning ring 5. Meanwhile, the inclined surface 31 of the sealing ring 3 moves towards the direction of the pipeline by pushing and pressing the locking piece 6, so that the sealing ring is tightly pressed with the pipeline, and the sealing performance is improved. By arranging the positioning ring 5, the deflection displacement of the pipeline can be avoided when the pipeline is locked. By the technical scheme, the pipeline connecting device can be conveniently assembled during pipeline connection and is convenient for later maintenance and disassembly; in addition, the sealing performance is better, and the installation is not easy to deviate.
In this embodiment, the inner wall of the positioning ring 5 is provided with the elastic convex portion 53, the elastic convex portions 53 are arranged around the positioning ring, and by arranging the elastic convex portions 53, the pipeline can be compressed by the elastic convex portions 53, so that the connection is more stable. In this embodiment, the positioning ring may be made of elastic material such as metal, plastic, etc.
In this embodiment, the opening 52 is disposed along the axial direction of the positioning ring 5 and penetrates the positioning ring, so that the positioning ring can be contracted or expanded.
In this embodiment, the pipe diameter of the connecting pipe 2 is greater than that of the main body 1, so that the connecting pipe can accommodate the insertion of a pipeline.
In this embodiment, the locking member 6 has a positioning portion 63, and the positioning portion 63 is disposed on one side of the external thread, so that when the locking member 6 is rotated, the locking member can be coupled with the positioning portion by a tool to accelerate screwing; the locating portion 63 may be hexagonal in shape, fitting a hexagonal sleeve for operation.
The connecting device of the electric actuator can be conveniently mounted and dismounted, and the convenience of maintenance is improved; in addition, the pipeline connection has good sealing performance and is not easy to leak.
It should be noted that the above-mentioned preferred embodiments are only for illustrating the technical concepts and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and to implement the present invention accordingly, and the protection scope of the present invention cannot be limited thereby. All equivalent changes and modifications made according to the spirit of the present invention should be covered by the protection scope of the present invention.
