Description

Technical Field

[0001] The utility model relates to the technical field of fluid control tools, in particular to a quick-insertion structure for a solenoid valve. Background Art

[0002] Solenoid valve is an industrial device controlled by electromagnetics. It is a basic component for fluid automation control. It is not only used in hydraulic and pneumatic systems, but can also be extended to various fluid control fields. It plays an important role in industrial automation control systems and can accurately control multiple parameters such as the direction, flow rate, and speed of the medium. Combined with different circuit designs, the solenoid valve can ensure that the predetermined control target is achieved and show high control accuracy and flexibility.

[0003] There are various types of solenoid valves, each of which performs different functions in the control system. The more common ones include check valves, safety valves, directional control valves, and speed control valves.

[0004] Solenoid valves are usually equipped with interfaces for connecting to pipelines, such as plug connectors, which are usually connected to pipelines by interference fit. For traditional solenoid valves with small size and multiple plug connectors arranged in parallel, the spacing between two adjacent plug connectors is designed to be relatively compact, which to a certain extent brings difficulty to operators when assembling pipelines, thereby possibly reducing the working efficiency when connecting the solenoid valve to the pipeline.

DETAILED DESCRIPTION

[0019] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0020] like Figures 1 to 3As shown, the utility model is a quick-insert structure for a solenoid valve, the solenoid valve comprises a control box 1 and a feed unit and a discharge unit arranged in the control box 1, the feed unit and the discharge unit are both equipped with a plurality of plug connectors 2 located outside the control box 1 to achieve convenient docking with external pipelines. The docking adopts an advanced quick-insert structure design, which includes the following components:

[0021] The main body 3 is tightly combined with the control box 1 by means of a snap connection. At least two installation cavities 4 are preset on the main body 3, and these installation cavities 4 are seamlessly sealed and connected with the plug connector 2. Each installation cavity 4 has a corresponding pipe connector 5, and the pipe connector 5 has a through hole communicating with the installation cavity 4. It is worth noting that the spacing between two adjacent pipe connectors 5 is specially designed to be larger than the spacing between adjacent plug connectors 2. Such a layout greatly simplifies the connection process between the pipeline and the solenoid valve, so that whether the pipeline is fixed to the pipe connector 5 in advance or the main body 3 is snapped to the control box 1 first and then the pipeline is connected, the work efficiency and convenience can be improved.

[0022] In the preferred design, the pipe joint 5 and the main body 3 are formed in one piece, which enhances the integrity and stability of the structure.

[0023] In addition, the control box 1 is designed with two or more symmetrically distributed snap-in grooves 6, and the main body 3 is provided with corresponding snap-in protrusions 7. The snap-in protrusions 7 are movably snap-in with the snap-in grooves 6. This design ensures a stable snap-in relationship between the main body 3 and the control box 1.

[0024] In the specific structure of the control box 1, it has three dimensions: length direction L, width direction W and height direction H, and the axial direction of the plug connector 2 is parallel to the width direction W of the control box 1. In order to better achieve the snap connection, the side wall of the control box 1 extends outward at a position parallel to the width direction W to form a snap connection portion, and the snap connection groove 6 penetrates the wall thickness of the snap connection portion along the height direction H. When assembling the control box 1 and the main body 3, first ensure that the installation cavity 4 on the main body 3 corresponds to the plug connector 2 on the control box 1 one by one, and then push the main body 3 smoothly along the width direction W. When the plug connector 2 is fully inserted into the installation cavity 4, the snap connection protrusion 7 can be smoothly embedded in the snap connection groove 6, thereby firmly fixing the main body 3 on the control box 1.

[0025] In order to facilitate the clamping protrusion 7 to smoothly enter the clamping groove 6, an inclined guiding slope 9 is specially provided on the side of the clamping portion away from the control box 1.

[0026] Finally, a sealing groove 10 is provided on the outer wall of the plug connector 2, and a sealing ring 11 is installed in the groove. The outer diameter of the sealing ring 11 is larger than the inner diameter of the installation cavity 4. The purpose of this design is to use the sealing ring 11 to effectively achieve the sealing between the plug connector 2 and the installation cavity 4, ensuring that the entire solenoid valve has good sealing performance and working efficiency.

If the specific posture changes, the directional indication will also change accordingly.
