[0021] Reference Figure 1-5 The image shown is a preferred embodiment of the present invention.

[0022] A multi-functional simulation test machine includes a body 10, a cabinet cavity 11 with a rear opening in the body 10, and a plurality of wiring terminals 12 in the cabinet cavity 11. The wiring terminals 12 have an input end and an output end that is connected to the cabinet machine under test. The body 10 has a central platform 20 that protrudes forward in the middle, and an operation panel 30 that is inclined in the upper part of the body 10. The operation panel 30 is formed at the front end of the body 10 and is inclined backward in the direction from bottom to top along the operation panel 30. The operation panel 30 is equipped with multiple control switches 31 that output control signals. The control switches 31 are exposed on the operation panel 30 and are electrically connected to the input terminal. The control signals emitted by the control switches 31 are transmitted to the cabinet under test through the terminal block 12.

[0023] The aforementioned multi-functional simulation tester features multiple wiring terminals 12 within the cabinet cavity 11 of the main body 10. Each wiring terminal 12 has an input terminal and an output terminal for connecting to the test cabinet. This design facilitates connection to different test cabinets, adapts to the testing needs of various cabinets, and exhibits good versatility. The central platform 20 can be used to place test-related tools, accessories, or temporary records, allowing operators to easily access them during testing, improving operational convenience and optimizing the testing process. The operation panel 30 is angled at the front of the main body 10, tilting backward from bottom to top, conforming to ergonomic design principles. This tilt angle makes it more comfortable for operators to operate the control switch 31, reducing fatigue from prolonged operation. Simultaneously, the control switch 31 is visible on the operation panel 30, facilitating quick identification and operation by the operator, greatly improving operational convenience and thus enhancing testing efficiency. This design solves the problem of relatively limited functionality in testing devices.

[0024] In this embodiment, the control switch 31 includes a toggle switch that outputs a digital control signal. Thus, the toggle switch can output a stable digital control signal, which has the characteristics of strong anti-interference capability, fast transmission speed, and clear logic.

[0025] In this embodiment, the control switch 31 includes a toggle switch that outputs an analog control signal. An analog signal generator 13 is provided in the cabinet cavity 11. The toggle switch is electrically connected to the analog signal generator 13. The toggle switch controls the change of the analog control signal emitted by the analog signal generator 13 by toggling.

[0026] The toggle switch, in conjunction with the analog signal generator 13, can output continuously changing analog control signals, such as changes in physical quantities like voltage and current. This allows the testing device to simulate various analog signal environments that the cabinet may encounter in actual operation, such as changes in the output signals of analog sensors like temperature and pressure. This meets the testing requirements for the cabinet's analog input function and expands the applicability of the testing device.

[0027] Operators can easily adjust the magnitude of the analog signal by turning the switch. The operation is simple and intuitive, improving the flexibility of analog signal testing.

[0028] In this embodiment, multiple terminals 12 are arranged in rows to form a strip-shaped terminal block; this allows the numerous terminals 12 to be arranged in an orderly manner, avoiding messy tangling of the wires.

[0029] During the wiring process, operators can quickly identify and distinguish different terminals 12, reducing the possibility of wiring errors and improving wiring efficiency; at the same time, the neat terminal blocks also facilitate the later inspection, maintenance and modification of the lines, reducing the difficulty of line management.

[0030] In this embodiment, the operation panel 30 is provided with a digital display 32 that displays the magnitude of the analog control signal, and the digital display 32 is electrically connected to the toggle switch.

[0031] The digital display 32 is electrically connected to the toggle switch, which can display the specific value of the analog control signal in real time and accurately, providing an intuitive reference for the operator. The operator can precisely adjust the toggle switch according to the reading of the digital display 32 to make the analog control signal reach the required accurate value for testing, thereby improving the accuracy and controllability of analog signal testing.

[0032] In this embodiment, the upper part of the body 10 has a recessed mounting groove 14, the operation panel 30 is embedded in the mounting groove 14, and the control switch 31 is exposed outside the mounting groove 14.

[0033] The mounting slot 14 provides a stable mounting position for the operation panel 30, allowing the operation panel 30 to be firmly embedded in the body 10, reducing the shaking of the operation panel 30 during use and ensuring operational stability.

[0034] After the control panel 30 is embedded in the mounting groove 14, the overall structure is more compact and aesthetically pleasing. At the same time, the mounting groove 14 protects the edges of the control panel 30, reducing damage to the control panel 30 from external collisions. The control switch 31 is exposed outside the mounting groove 14, making it convenient for operators to operate directly and avoiding obstruction of operation by the mounting groove 14.

[0035] In this embodiment, the lower part of the operation panel 30 is placed in the mounting groove 14 and hinged to the body 10. The upper part of the operation panel 30 is provided with a connector 40 that is detachably connected to the body 10. The connector 40 is inserted into the body 10 so that the operation panel 30 and the body 10 are relatively fixed.

[0036] The lower part of the operation panel 30 is hinged to the body 10, allowing the operation panel 30 to rotate around the hinge point, thus realizing the opening and closing function of the operation panel 30. When it is necessary to inspect or maintain the circuits or components on the back of the operation panel 30, simply open the operation panel 30. The operation is convenient and quick, reducing the difficulty of maintenance. The connector 40 detachably connects the upper part of the operation panel 30 to the body 10, and can firmly fix the operation panel 30 when it is closed, preventing the operation panel 30 from being accidentally opened during use, thus ensuring the safety and stability of operation; at the same time, the detachable connection design also facilitates the disassembly and replacement of the operation panel 30.

[0037] In this embodiment, the outer end of the connector 40 has an outer end head 41, the inner end of the connector 40 has an inner end head 42, and the bottom of the mounting groove 14 has a bottom wall with a locking hole 15 in the bottom wall. The connector 40 passes through the control panel 30, with the outer end 41 abutting against the outer side of the control panel 30 and exposed on the control panel 30; the inner end 42 passes through the inner side of the control panel 30 and is fixedly inserted into the locking hole 15 so that the control panel 30 is fixed in the mounting groove 14.

[0038] The outer end 41 of the connector 40 abuts against the outside of the operation panel 30, which limits the connector 40 and prevents it from going too deep into the operation panel 30; the inner end 42 is fixedly inserted into the locking hole 15, realizing a reliable connection between the operation panel 30 and the body 10 and ensuring the stability of the connection. The connector 40 has a simple and reasonable structural design, and is easy to install and disassemble. Through the cooperation of the outer end 41 and the inner end 42, the stability of the operation panel 30 in the fixed state and the convenience of opening it when needed can be effectively ensured.

[0039] In this embodiment, the connector 40 is threadedly connected to the operation panel 30, and the inner end 42 is an elastic body that can deform elastically. The inner end 42 passes through the locking hole 15 and is in an elastically compressed state when squeezed.

[0040] The connector 40 is threaded to the control panel 30, making it easier to install and remove the connector 40. By rotating the connector 40, it can be fixed and separated from the control panel 30, making the operation simple and effortless.

[0041] The inner end 42 is an elastically deformable elastomer. After passing through the locking hole 15, it is squeezed and in an elastically compressed state. The elastic restoring force of the elastomer makes the inner end 42 fit tightly with the locking hole 15, which further enhances the connection strength and stability between the connector 40 and the machine body 10, prevents the connector 40 from loosening, and ensures the firm fixation of the operation panel 30. At the same time, the elasticity of the elastomer also plays a certain buffering role, reducing the impact of vibration of the operation panel 30 on the connection during use.

[0042] In this embodiment, the lower part of the body 10 is provided with a front opening, which is formed at the front end of the body 10 and located below the middle platform 20; the front opening is connected to the cabinet cavity 11, and the front opening is provided with a front door 50 for opening or closing the front opening. The rear end of the body 10 is provided with a rear opening that connects to the cabinet cavity 11. The rear opening extends along the height direction of the body 10 and is provided with a rear door 60 for opening or closing the rear opening.

[0043] When wiring, maintenance or other operations are required inside the lower cabinet cavity 11, the front door 50 can be opened for convenient operation without disassembling the body 10 parts from other parts, thus improving the convenience of operation. When the front door 50 is closed, it can protect the lower cabinet cavity 11 from dust and moisture and protect the internal components. The large size of the rear opening facilitates comprehensive observation and operation of the interior of the cabinet 11 from the rear of the unit 10. It provides ample operating space, especially when installing, disassembling, or adjusting the overall wiring layout of large components inside the cabinet 11, greatly improving the efficiency of maintenance and installation. When the rear door 60 is closed, it can provide overall protection for the interior of the cabinet 11, preventing external debris from entering the interior of the cabinet 11.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
