Description

Technical Field

[0001] This utility model relates to the field of industrial washing machines, specifically to a switching power supply for an industrial washing machine control board. Background Technology

[0002] An industrial washing machine is a device used for washing large quantities of clothes. It is mainly used in laundry rooms of large places such as garment factories, laundries, schools, hotels, and hospitals. The control board switching power supply is one of the many components of an industrial washing machine. It is a device that provides current voltage to electronic equipment. The power control board is a device that provides current voltage to electronic equipment. It is also called a power controller. It provides control over the current required by all components in the power supply. The switching power supply is generally composed of four main parts: main circuit, control circuit, detection circuit, and auxiliary power supply.

[0003] A search revealed a switching power supply with publication number CN215300476U, specifically disclosing a switching power supply. This utility model discloses a switching power supply including a housing and a PCB board disposed within the housing. The PCB board has a switching power supply circuit and also includes a clamping component. The housing is a thermally conductive housing. The power devices on the PCB board are pressed against the inner wall of the housing by the clamping component for thermal contact. The power devices of this utility model have good heat dissipation, improving the stability, reliability, and efficiency of circuit operation, and extending service life.

[0004] In the operation of existing industrial washing machine control board switching power supplies, due to the large vibrations of industrial washing machines, if the control board switching power supply is simply connected to the industrial washing machine, the power cord at the connection point is prone to coming loose over long-term use, causing industrial washing machine malfunctions. Moreover, the industrial washing machine control board switching power supply in the aforementioned comparative case also lacks a method to prevent wire disconnection. Thus, after long-term use, troubleshooting industrial washing machines that suddenly lose power requires a certain amount of time, thereby delaying the normal use of industrial washing machines.

[0005] Therefore, it is necessary to invent a switching power supply for an industrial washing machine control board to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a switching power supply for an industrial washing machine control board. Through the industrial washing machine control circuit board, wiring gate, wiring board, connecting bolts, clamping washers, and anti-detachment opening, when the power cord is detached due to vibration from the industrial washing machine, it is first restricted and blocked by the connecting bolts and clamping washers. Then, the power cord drives the anti-detachment plate to move towards the anti-detachment opening outlet, where it is blocked by the clamping clamp, thus preventing the circuit from detaching. This combination reduces the probability of power cord detachment at the connection point and causing industrial washing machine malfunctions over long-term use. This adds a method to prevent detachment, ensuring the normal operation of the industrial washing machine. It solves the problem in existing industrial washing machine control board switching power supplies where, due to the large vibrations of industrial washing machines during operation, a simple connection between the control board switching power supply and the industrial washing machine easily leads to power cord detachment at the connection point over long-term use, causing industrial washing machine malfunctions. Furthermore, the industrial washing machine control board switching power supplies in the aforementioned comparative cases also lacked a method to prevent detachment, thus requiring considerable time to troubleshoot sudden disconnections after long-term use, delaying the normal operation of the industrial washing machine.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a switching power supply for an industrial washing machine control board, including an industrial washing machine control board switch housing, used for connecting the circuit board and the industrial washing machine;

[0008] Fixing bolts are installed inside the switch housing of the industrial washing machine control board for connecting and installing the industrial washing machine control circuit board, and wiring grids are fixedly installed on the outside of the switch housing of the industrial washing machine control board.

[0009] A junction box is located inside the junction box to assist in connecting external connection wires to the internal circuit board. A connecting bolt passes through the top of the junction box, and a clamping washer is provided below the connecting bolt.

[0010] An anti-detachment port is located inside the wiring grid to enhance the ability of external connecting wires to prevent detachment inside the wiring grid. An anti-detachment plate is installed inside the anti-detachment port, and a fixing screw passes through the top of the anti-detachment port. A wire clamp is fixedly installed at one end of the fixing screw.

[0011] Preferably, an mounting plate is fixedly installed on the outside of the switch housing of the industrial washing machine control board, and a positioning bolt passes through the top of the mounting plate.

[0012] Preferably, an outer positioning post is fixedly installed on the top of the industrial washing machine control board switch housing, an inner positioning post is movably connected inside the outer positioning post, a control board switch housing cover is fixedly installed on the top of the inner positioning post, and a fastening bolt passes through the top of the control board switch housing cover.

[0013] Preferably, the surface of the control board switch housing cover is provided with heat dissipation vents, and a drive display controller is fixedly installed on the top of the control board switch housing cover.

[0014] Preferably, the clamping gasket is movably connected to the connecting bolt, and the terminal block is evenly distributed on the terminal grid.

[0015] Preferably, the anti-detachment plate is movably connected to the anti-detachment opening, and the fixing screw and the pressure clamp are vertically distributed.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. This utility model includes an industrial washing machine control circuit board, a wiring grid, a wiring board, connecting bolts, clamping washers, and an anti-detachment port. When this device is connected to an industrial washing machine, the internal power cord of the industrial washing machine is passed through the wiring grid and connected to the industrial washing machine control circuit board. Then, the connecting bolts are turned to allow the clamping washers to press the power cord passing through the wiring grid onto the wiring board, forming a secondary fixation. Next, the fixing screws are turned to allow the wire clamp to press the power cord at the end of the wiring grid into the anti-detachment port, completing a tertiary fixation. In this way, when the power cord comes loose due to vibration from the industrial washing machine, it is first restricted and blocked by the connecting bolts and clamping washers. Then, the power cord drives the anti-detachment plate to move towards the outlet of the anti-detachment port, where it is blocked by the wire clamp, thus preventing the circuit from coming loose. This combination reduces the probability of the power cord coming loose at the connection point during long-term use, thereby preventing industrial washing machine malfunctions. This adds an anti-detachment method to the switching power supply of the industrial washing machine control board, ensuring the normal operation of the industrial washing machine.

[0018] 2. This utility model is equipped with an outer positioning post, an inner positioning post, a control board switch housing cover, fastening bolts, and heat dissipation vents. When this device is connected and installed with an industrial washing machine, the outer positioning post on the top of the industrial washing machine control board switch housing facilitates docking with the inner positioning post of the control board switch housing cover. This avoids misalignment during the installation or removal of the control board switch housing cover. Furthermore, multiple heat dissipation vents are provided on the surface of the control board switch housing cover. When the circuit board inside the industrial washing machine control board switch housing is running under high load, the heat accumulated inside can be ventilated and dissipated, reducing the occurrence of high temperature overload of the internal components of the industrial washing machine control board switch housing under high load.

[0028] This utility model provides, for example Figure 1-5 The diagram shows a switching power supply for an industrial washing machine control board, including an industrial washing machine control board switch housing 1, which is used for connecting the circuit board to the industrial washing machine.

[0029] A fixing bolt 10 is located inside the industrial washing machine control board switch housing 1 for connecting and installing the industrial washing machine control circuit board 11, and a wiring grid 12 is fixedly installed on the outside of the industrial washing machine control board switch housing 1.

[0030] A junction box 13 is located inside the junction box 12 to assist the external connection wires in connecting to the internal circuit board. A connecting bolt 14 passes through the top of the junction box 13, and a clamping washer 15 is located below the connecting bolt 14.

[0031] An anti-detachment port 16 is located inside the wiring grid 12 to enhance the anti-detachment capability of external connection wires inside the wiring grid 12. An anti-detachment plate 17 is provided inside the anti-detachment port 16. A fixing screw 18 passes through the top of the anti-detachment port 16. A wire clamp 19 is fixedly installed at one end of the fixing screw 18. Twisting the connecting bolt 14 allows the clamping washer 15 to press the power wire passing through the wiring grid 12 onto the wiring plate 13 to form a secondary fixation. Then, the fixing screw 18 is twisted again to allow the wire clamp 19 to press the power wire at the end of the wiring grid 12 inside the anti-detachment port 16 to complete the tertiary fixation.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, an installation plate 2 is fixedly mounted on the outside of the industrial washing machine control board switch housing 1. A positioning bolt 3 passes through the top of the installation plate 2. The installation plate 2 and the positioning bolt 3 facilitate the connection and installation of the industrial washing machine control board switch power supply with different industrial washing machines. An outer positioning post 4 is fixedly mounted on the top of the industrial washing machine control board switch housing 1. An inner positioning post 5 is movably connected inside the outer positioning post 4. A control board switch housing cover 6 is fixedly mounted on the top of the inner positioning post 5. A fastening bolt 7 passes through the top of the control board switch housing cover 6. The outer positioning post 4 is located on the top of the industrial washing machine control board switch housing 1. It can be installed by docking with the inner positioning post 5 of the control board switch housing 6, thus avoiding misalignment during the installation or removal of the control board switch housing 6. The surface of the control board switch housing 6 is provided with heat dissipation vents 8, and the drive display controller 9 is fixedly installed on the top of the control board switch housing 6. The multiple heat dissipation vents 8 on the surface of the control board switch housing 6 can ventilate and dissipate heat when the circuit board inside the industrial washing machine control board switch housing 1 is running under high load, reducing the occurrence of high temperature overload of the internal components of the industrial washing machine control board switch housing 1 during high load operation.

[0033] like Figure 1 , Figure 4 and Figure 5 As shown, the clamping pad 15 is movably connected to the connecting bolt 14. The terminal block 13 is evenly distributed on the terminal grid 12. The clamping pad 15 can form a secondary fixation for the power line passing through the terminal grid 12 and also prevent the power line from falling off.

[0034] The working principle of this utility model is as follows: First, the mounting plate 2 and positioning bolts 3 facilitate the connection and installation of the industrial washing machine control board power supply with different industrial washing machines. Then, the switch housing 1 of the industrial washing machine control board is opened, and the internal power cord of the industrial washing machine is passed through the wiring grid 12 and connected to the industrial washing machine control circuit board 11. Next, the connecting bolt 14 is turned so that the clamping washer 15 presses the power cord passing through the wiring grid 12 onto the wiring plate 13 to form a secondary fixation. Then, the fixing screw 18 is turned so that the wire clamp 19 presses the power cord at the end of the wiring grid 12 inside the anti-detachment port 16 to complete the tertiary fixation. In this way, when the power cord is dislodged by the vibration of the industrial washing machine, it is first restricted and blocked by the connecting bolt 14 and the clamping washer 15. Then, the power cord drives the anti-detachment plate 17 to move towards the outlet of the anti-detachment port 16, and is blocked by the wire clamp 19 to prevent the circuit from disconnecting. After the power cord is connected, the industrial washing machine control board is... The outer positioning post 4 on the top of the switch housing 1 is aligned with the inner positioning post 5 of the control board switch housing cover 6. This prevents misalignment during installation or removal of the control board switch housing cover 6. Multiple heat dissipation vents 8 are then provided on the surface of the control board switch housing cover 6. During high-load operation of the circuit board inside the industrial washing machine control board switch housing 1, this allows for ventilation and heat dissipation, reducing the risk of overheating and overload of internal components.
