[0019] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0020] According to an embodiment of the utility model, a diaphragm pump control device for automatically switching a standby pump is provided. Example

[0021] like Figure 1 As shown, the diaphragm pump control device for automatically switching the standby pump according to the embodiment of the utility model includes a PLC controller 1 and a connecting block 2 connected to the top of the PLC controller 1, a plurality of groups of connecting ports 3 are arranged on the outer end surface of the connecting block 2, a vertically arranged table plate 4 is provided on one side of the connecting port 3, a through hole 5 matching the connecting port 3 is opened on the table plate 4, and an anti-slip rubber pad is provided at the bottom end of the PLC controller 1. Example

[0022] like Figure 2 As shown, a fence 6 is provided on the outer sleeve of the connecting block 2, and the fence 6 is connected to the table 4. An electric turntable 7 is provided at the junction of the fence 6 and the top of the PLC controller 1. A plurality of plug-in ports 8 corresponding to the connecting port 3 are provided on the fence 6. The plug-in port 8 is slightly larger than the through hole 5. A limit plate 9 is provided in the plug-in port 8. A push rod is provided on the end of the limit plate 9 away from the plug-in port 8. A slide groove for sliding the table 4 is provided on the top of the PLC controller 1. A telescopic sleeve 10 is provided at the junction of the table 4 and the fence 6. A card slot 11 is provided on one side of the connecting block 2 close to the through hole 5. A card block 12 matching the card slot 11 is provided on one side of the table 4 close to the card slot 11. The card block 12 includes a main body 13 and a limit block 14 arranged on one side of the main body 13. A spring rod 15 is provided at the junction of the limit block 14 and the main body 13. A cylinder is provided at the junction of the limit block 14 and the main body 13. Grooves for sliding the spring rod 15 are provided on both sides of the cylinder. A wiring terminal is provided on the end of the through hole 5 close to the connecting port 3.

[0023] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0024] In actual application, when in use, after the fence 6 and the table 4 are rotated to the appropriate position, the wires are inserted into the wiring terminals in the through hole 5, and then the wires are connected to the connection port 3 through the telescopic sleeve 10. At this time, the telescopic sleeve 10 is naturally unfolded to protect the wires inside. At this time, the table 4 will be connected to the connection block 2 through the card slot 11 and the card block 12. During the connection, the limit block 14 in the card block 12 is actively connected to the main body 13, and when inserted into the card slot 11, the limit block 14 is forced toward the main body 13. The spring rod 15 is then squeezed by the limit block 14 and slides downward, so that the card block 12 can enter the card slot 11. After reaching the appropriate position, the limit block 14 is naturally unfolded to clamp the card block 12 in the card slot 11. When disassembling, it is only necessary to press the table plate 4 in the direction of the connecting block 2, and the fence 6 can be rotated so that the fence 6 can be connected to the wires in different directions, thereby improving the applicability of the device. As for the working principle of the PLC controller 1 and how to achieve switching, it is common knowledge known in the industry and will not be elaborated on here.

[0025] To sum up, with the help of the above-mentioned technical solution of the utility model, the device can be more convenient to connect wires, and no additional tools are required. It only needs to extend the telescopic sleeve 10 to connect the table 4 with the connecting block 2 through the card slot 11 and the card block 12. At this time, the wiring terminal will extend into the connection port 3 to complete the connection of the wires. After the connection is completed, the telescopic sleeve 10 will naturally unfold, which can play a protective role for the wires. Since the fence 6 can be rotated by the electric turntable 7, no matter which direction the source of the wires is in, it can be connected, which improves the applicability of the device.

[0026] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
