[0028] In one embodiment, such as Figures 1-6 As shown, a desktop electrically controlled pneumatic power source includes:

[0029] Base plate 1, which is made of aluminum alloy material;

[0030] The base 2 has four sets, which are respectively located below the four corners of the lower end face of the base plate 1;

[0031] The mounting slot 3 has four sets, which are respectively located at the four corners of the lower end face of the base plate 1;

[0032] Mounting plate 4 is provided in four sets, and is respectively located inside the four sets of mounting slots 3;

[0033] An adjustment component is provided for adjusting the balance of the base plate 1. Four sets are provided, which are respectively set on the four sets of mounting plates 4. The adjustment component includes a slot 5, which is set on the lower end surface of the mounting plate 4. A locking rod 6 is provided inside the slot 5, and an adjustment component is provided on the locking rod 6.

[0034] The adjusting component includes a screw 7, which is connected to the end face of the lever 6. The other end of the screw 7 is provided with a rotating block 8, which is connected to the end face of the base 2. A screw block 9 is threaded on the outer side of the screw 7. Two sets of support plates 10 are provided on the side wall of the screw block 9. A set of support blocks 11 is provided on the other end face of each of the two sets of support plates 10. Both sets of support blocks 11 are connected to the side wall of the mounting plate 4.

[0035] Specifically, during use, when the height of the four corners of the base plate 1 needs to be adjusted, the corresponding rotating block 8 is rotated. The rotating block 8 drives the screw 7 to rotate. With the cooperation of the screw block 9, the screw 7 can drive the rotating block 8 to move, thereby driving the base 2 to move. This allows the base plate 1 to be balanced under the adjustment of the four sets of bases 2, thus putting the base plate 1 in a balanced state. By setting the adjustment assembly consisting of the slot 5, the lever 6 and the adjusting parts, the height of the four corners of the base plate 1 can be adjusted, so that the base plate 1 is in a balanced state. This facilitates the multiple sets of components above the base plate 1 to detect the workpiece, improves the accuracy of the detection, and avoids problems such as low accuracy and efficiency, uneven pressure, and inconvenient reading.

[0036] like Figures 1-5 As shown, a set of mounting screw holes 12 is provided at each of the four corners of the inner wall of the mounting groove 3, and a set of mounting bolts 13 is provided at each of the four corners of the mounting plate 4. The mounting screw holes 12 and the mounting bolts 13 are used together. By providing multiple sets of mounting screw holes 12 and mounting bolts 13, the mounting plate 4 can be installed or fixed, which is quite convenient.

[0037] like Figures 1-2 As shown, a pressure regulating valve 14 is installed on the upper surface of the base plate 1. The pressure regulating valve 14 is used for increasing or decreasing pressure, and can also be used for fine adjustment. A shut-off valve 15 is installed on the right side of the pressure regulating valve 14. The shut-off valve 15 needs to be closed after pre-pressurization. A pre-pressurization pump 16 is installed on one side of the shut-off valve 15. The pre-pressurization pump 16 can pre-pressurize to 1.2-1.6MPa, and an electrically connected variable frequency drive 161 is installed above the pre-pressurization pump 16. The variable frequency drive 161 is equipped with a control button, which controls the operation of the pre-pressurization pump 16. The pressure regulating valve 14 is located on one side of the base plate 14. The device features three sets of output interfaces 17 for connecting to the tested or standard instruments. A positive / negative pressure reversing valve 18 is located on the left side of the pressure regulating valve 14, closing during pressurization and opening during depressurization. Multiple sets of output interfaces 17 are connected to the tested or standard instruments, and the tested workpiece is then inspected via the pressure regulating valve 14, shut-off valve 15, pre-pressurization pump 16, and positive / negative pressure reversing valve 18 on the base plate 1. It boasts advantages such as small size, light weight, portability, simple operation, wide applicability, accurate and reliable test data, and broad versatility. It is rust-proof, corrosion-resistant, lightweight, easy to operate, safe and reliable, portable, and widely applicable, meeting the testing requirements of pressure gauges within all pressure ranges. It has three output pressure ports, allowing simultaneous testing of three pressure gauges. It employs an electric control method to avoid operator fatigue and slow efficiency. A constant-speed pressurization mode ensures constant and stable pressurization.

[0038] The above embodiment discloses a desktop electrically controlled pneumatic power source. In use, when the height of the four corners of the base plate 1 needs to be adjusted, the corresponding rotating block 8 is rotated. The rotating block 8 drives the screw 7 to rotate. With the cooperation of the screw block 9, the screw 7 can drive the rotating block 8 to move, thereby moving the base 2. This allows the base plate 1 to achieve balance under the adjustment of the four sets of bases 2, thus ensuring the base plate 1 is in a balanced state. Subsequently, multiple output interfaces 17 are connected to the instrument being tested or a standard instrument. Then, the workpiece is tested through the pressure regulating valve 14, shut-off valve 15, pre-pressure pump 16, and positive / negative pressure reversing valve 18 on the base plate 1. It has advantages such as small size, light weight, portability, simple operation, wide applicability, accurate and reliable test data, and wide versatility.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
