DETAILED DESCRIPTION

[0020] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0021] Please refer to Figures 1-4It can be known that the utility model provides a technical scheme: a unit valve is with general controller, include: controller box body 1, mounting plate 2, side plate 3, terminal row 4 and wiring tube 5, the front and rear of controller box body 1 are connected with mounting plate 2, the both sides of controller box body 1 are installed with side plate 3, the outside of two side plates 3 is installed with terminal row 4, the outside of a side plate 3 is installed with wiring tube 5, the top of controller box body 1 is installed with connecting shaft 6, the outside of connecting shaft 6 is rotatably connected with connecting plate 7, the surface of connecting plate 7 is installed with connecting block 8, the inside of connecting block 8 is passed through and is set up U-shaped groove 9, the inner wall of U-shaped groove 9 is connected with rubber protrusion 10, the surface of controller box body 1 near connecting shaft 6 is connected with fixed block 11, the inside of fixed block 11 is screw-threaded and is connected with screw knob 12, the inside of fixed block 11 is passed through and is inserted with limit insert block 13, the rotatory structure is formed between connecting plate 7 and connecting shaft 6, the insert structure is formed between limit insert block 13 and fixed block 11.

[0022] When the unit valve general controller is used in industrial automation control system, if the terminal row 4 on the controller is not fixed firmly when connecting the wire harness, the wire harness and the terminal row 4 are prone to looseness, and the wire harness is prone to looseness when being accidentally touched or pulled, so that the controller is difficult to use normally. After the wire harness and the terminal row 4 are fixed, the connecting plate 7 can be pulled towards the terminal row 4. When the connecting plate 7 moves, the connecting plate 7 can be rotated by the connecting shaft 6. When the connecting plate 7 rotates, the connecting block 8 can be rotated and moved. When the connecting block 8 rotates and moves to the outside of the terminal row 4, the end of the connecting block 8 faces downward, and the connecting plate 7 is located above the terminal row 4. Thus, the limit insert block 13 can be pushed towards the connecting plate 7. When the limit insert block 13 moves, the end of the limit insert block 13 can move to the top surface of the connecting plate 7. When the limit insert block 13 moves to the maximum distance, the screw knob 12 can be tightened, so that the end of the screw knob 12 can screw the limit insert block 13. At this time, the limit insert block 13 can limit the connecting plate 7, so that the connecting plate 7 is not prone to looseness. Then the wire harness connected with the terminal row 4 is clamped into the U-shaped groove 9, so that the wire harness is extruded and limited by the rubber protrusion 10, and the wire harness is not prone to looseness.

[0023] Referring to Figures 1-4 It can be known that the connecting block 8 can assist in limiting the wire harness connected with the terminal row 4, so that the wire harness and the terminal row 4 are not prone to looseness, thereby improving the firmness of the connection between the wire harness and the terminal row 4.

[0024] Referring to Figure 1 And Figure 5It can be seen that the bottom of the controller box 1 is connected to a support base 14, the inside of the support base 14 is provided with a through hole 15, the inner wall of the through hole 15 is connected to a plastic flexible plate 16, and a locking block 17 is connected to the opposite side of the two plastic flexible plates 16. A heat insulation plate 18 is provided below the support base 14, and a docking block 19 is connected to the heat insulation plate 18 near the top of the support base 14. The docking block 19 and the support base 14 form a plug-in structure through the through hole 15.

[0025] In specific implementation, when the unit valve universal controller is installed, its bottom will directly contact the mounting surface, making it difficult for the heat at the bottom of the controller box 1 to dissipate, which may affect the mounting surface. When installing the controller box 1, the controller box 1 can be moved directly above the heat insulation plate 18 and slowly lowered. When the controller box 1 is lowered to a certain height, the end of the docking block 19 can be inserted into the through hole 15. At this time, the end of the docking block 19 will press against the two sets of locking blocks 17. Due to the plastic soft plate 16 having a certain plasticity, when the locking block 17 is pressed by the docking block 19, the plastic soft plate 16 will bend away from the docking block 19. When the plastic soft plate 16 bends to its maximum extent, the docking block 19 can be completely docked with the support base 14. At this time, the locking block 17 can be reset by the plasticity of the plastic soft plate 16. When the locking block 17 is reset, it can engage with the docking block 19, thereby installing the heat insulation plate 18 at the bottom of the controller box 1. At this time, the controller box 1 can be installed.

[0026] See Figure 1 and Figure 5 As can be seen, after the controller box 1 is installed, the bottom of the heat insulation plate 18 is in contact with the mounting surface. When the controller box 1 generates heat, it can dissipate from its bottom. The heat insulation plate 18 can prevent the heat dissipated from the bottom of the controller box 1 from affecting the mounting surface.

[0027] In summary, when using the universal controller in this unit valve, after the wiring harness is fixed to the terminal block 4, the connecting plate 7 can be pulled towards the terminal block 4. When the connecting plate 7 moves, it can rotate through the connecting shaft 6. When the connecting plate 7 rotates, it can drive the connecting block 8 to rotate and move. The connecting block 8 can assist in limiting the wiring harness connected to the terminal block 4, making it less likely for the wiring harness to loosen with the terminal block 4, thereby improving the firmness of the connection between the wiring harness and the terminal block 4. After the controller box 1 is installed, the bottom of the heat insulation plate 18 contacts the mounting surface. When the controller box 1 generates heat, it can dissipate from its bottom. The heat insulation plate 18 can prevent the heat dissipated from the bottom of the controller box 1 from affecting the mounting surface. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0028] Although the utility model has been explained in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or make equivalent replacement to part of the technical features, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
