Description

Technical Field

[0001] This utility model relates to the field of power supply technology, and in particular to a support structure for a plasma power supply. Background Technology

[0002] In practical applications of plasma power supplies, the equipment often needs to be placed on surfaces or workbenches with varying degrees of flatness. Traditional support structures often use fixed legs, which are difficult to adapt to complex ground conditions, easily causing the equipment to tilt and affecting power supply stability. In addition, plasma power supplies have high requirements for the levelness of the working state. If the equipment tilts due to external forces or uneven ground, it may cause safety hazards such as internal plasma leakage and short circuits. Utility Model Content

[0003] This invention addresses the shortcomings of existing technologies by providing a support structure for a plasma power source.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A support structure for an plasma power supply includes a power supply housing; several support units distributed at the bottom of the power supply housing; and a horizontal detection unit including a detection ball, a housing, and several connecting rods. The detection ball is disposed within the housing, and the housing is disposed between the support units via the connecting rods. When the detection ball deflects to contact the outer wall of the housing, the plasma power supply is disconnected.

[0005] In the above scheme, preferably, the support unit includes a support foot and a support block located inside the support foot, the support block being slidably connected in the support foot.

[0006] In the above scheme, preferably, the support block and the support foot are connected by a tension spring, and when the tension spring is in a static state, the support block is housed in the support foot.

[0007] In the above scheme, preferably, an adjusting member is provided between the supporting leg and the supporting block, and a through hole is provided on the supporting leg for placing the adjusting member.

[0008] In the above scheme, preferably, the adjusting member includes a connecting column and a conical block at its end, the conical block being placed between the supporting foot and the supporting block.

[0009] In the above scheme, preferably, a fixing block is provided between the supporting foot and the supporting block, and the fixing block is provided with a connecting hole that matches the connecting column.

[0010] In the above scheme, preferably, the box body includes a groove for placing the detection ball, and the groove is located at the center of the box body.

[0011] In the above scheme, preferably, a first electrode is provided at the bottom of the box on one side of the groove, and a second electrode is provided on the side of the box. When the detection ball is in contact with the first electrode and the second electrode at the same time, the power supply body is de-energized.

[0012] In the above scheme, preferably, the connecting column is threaded onto the fixing block.

[0013] The beneficial effects of this invention are as follows: Through the sliding cooperation between the support feet and the support block, and the synergistic effect of the tensioning spring, the support unit, in conjunction with the fine-tuning function of the adjusting component, automatically adapts to ground undulations, achieving rapid level calibration and significantly improving the stability of equipment placement. The level detection unit adopts a mechanical trigger structure; when the equipment tilts beyond a threshold, the rolling contact electrode of the detection ball triggers power-off, resulting in fast response, high reliability, and effective prevention of plasma leakage or circuit failure.

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments: See below Figures 1-7 A support structure for an plasma power source includes a power source housing 1, several support units distributed at the bottom of the housing, and a horizontal detection unit.

[0022] Specifically, the support unit is provided in four sets. The support unit includes a support foot 2 and a support block 3 therein. The support block 3 is slidably connected inside the support foot 2 and is connected to the inner wall of the support foot 2 by a tension spring 4. Under normal conditions, the tension spring 4 retracts the support block 3 into the support foot 2, that is, the position of the support foot 2 does not protrude outside the support foot 2.

[0023] When the power supply is placed on an uneven surface, the support block 3 can extend downwards to adjust its height. Specifically, an adjusting member 5 is provided between the support block 3 and the support foot 2. The adjusting member 5 consists of a connecting post 7 and a conical block 8 at the end. A through hole 6 is opened at a suitable position on the side wall of the support foot 2. The connecting post 7 passes through the through hole 6 and is threadedly connected to the connecting hole 9 of the fixing block 10 between the support foot 2 and the support block 3. The connecting hole 9 is provided with a threaded hole that matches the connecting post 7.

[0024] A through hole 6 is opened on the side wall of the support foot 2. When the connecting column 7 is rotated, the conical block 8 abuts against the support block 3, thereby changing the length of the protruding part of the support foot 2, that is, realizing the fine adjustment of the height of the power supply body, so that it can be placed stably in any position.

[0025] Furthermore, to ensure the housing 15 is fixed between adjacent support units via connecting rods 16, a hemispherical groove 11 is provided at its center. A detection ball 12 is placed within the groove 11, with a first electrode 13 located at the bottom outer side of the groove 11 and a second electrode 14 located on the side wall of the housing 15. When the power supply is tilted, causing the detection ball 12 to roll and simultaneously contact the first electrode 13 and the second electrode 14, a conductive circuit is formed, triggering the automatic power-off. The arc design at the top of the groove 11 allows the detection ball 12 to deflect and trigger with slight tilting, resulting in high sensitivity.

[0026] When placing the power supply, the support block 3 at the bottom of the support foot 2 automatically extends and retracts according to the flatness of the ground, and is locked in position by the adjustment piece 5 to maintain the overall level. If external force causes the power supply to tilt beyond the threshold, the detection ball 12 contacts the electrode to trigger power cut-off, preventing leakage or damage to the plasma power supply due to tilting.

[0027] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
