Description

Technical Field

[0001] The utility model relates to the technical field of valve islands, in particular to a valve island assembly expansion structure. Background Art

[0002] The valve island is a pneumatic product that integrates solenoid valves, programmable controllers and fieldbuses. It effectively concentrates various solenoid valves on the valve island, unifies air intake, exhaust and wiring, greatly reduces the number of accessories and space, greatly simplifies the debugging, maintenance and performance testing of complex electrical systems, and has a wide range of application scenarios.

[0003] In the prior art, multiple solenoid valves are installed on a valve island, and then the valve island is installed on the rack of the corresponding equipment. This is conducive to the installation, management and maintenance of each solenoid valve. However, in the face of the installation requirements of a large number of solenoid valves, the problem of more convenient expansion of the valve island needs to be solved. Therefore, we propose a valve island assembly expansion structure. Utility Model Content

[0004] The purpose of the present utility model is to provide a utility model subject to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] As a preferred solution of the utility model, the plug-in slot corresponds to the position of the plug-in block.

[0008] As a preferred solution of the utility model, the limit blocks on both sides correspond to the positions of the limit grooves.

[0009] The technical effect of adopting the above further scheme is: by inserting the plug-in block of one valve island into the plug-in slot of another valve island, the limit blocks located on both sides of the plug-in block are also inserted into the limit slots of the other valve island, so that two or more valve islands are connected, thereby expanding the valve island.

[0010] As a preferred solution of the utility model, a return spring is sleeved on the periphery of the telescopic rod.

[0011] The technical effect of adopting the above further solution is that the telescopic rod is restored to its original position by the reset spring when the telescopic rod is not pressed by external force.

[0012] As a preferred solution of the utility model, arc grooves are provided on both sides of the limit block.

[0013] As a preferred solution of the utility model, engaging grooves are provided on both sides of the limit block and on the front side of the arc-shaped groove, and the arc-shaped groove is communicated with the engaging grooves.

[0014] The technical effect of adopting the above-mentioned further scheme is: after two or more valve islands are connected, the limit blocks located on both sides of the plug-in block are inserted into the limit groove of another valve island, and the arc groove on the limit block abuts the circular snap-in ball. The arc groove applies external force to the telescopic rod connected to the circular snap-in ball, so that the circular snap-in ball retracts until the circular snap-in ball abuts against the snap-in groove, and the reset spring on the telescopic rod is not subjected to external force pressure, so that the telescopic rod drives the circular snap-in ball to pop out, thereby connecting and fixing the two valve islands.

The arc grooves on the limit blocks abut against the circular snap-in balls. The arc grooves apply external force to the telescopic rod connected to the circular snap-in balls, causing the circular snap-in balls to retract until the circular snap-in balls abut against the snap-in grooves. The reset spring on the telescopic rod is not subjected to external force, so that the telescopic rod drives the circular snap-in balls to pop out, thereby connecting and fixing the two valve islands, and connecting two or more valve islands to expand the valve island. No connectors are required during the connection process, and the assembly and expansion process is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
