DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0028] Example 1

[0029] The present invention provides a high power pulse arc power supply, such as Figures 1 to 8 As shown, it includes a power supply housing 1, and electrical components are arranged inside the power supply housing 1. This is a structure in the prior art and will not be elaborated here. A switch 2 is fixedly installed on one end face of the power supply housing 1, and a control panel 3 is embedded and installed at a position on one side of the switch 2 of the power supply housing 1. Notches 4 are symmetrically provided at the bottom end of the power supply housing 1, and a flip support assembly 5 is installed at a position inside the notch 4 at the bottom end of the power supply housing 1. A height adjustment movable assembly 6 is movably installed inside the flip support assembly 5, and a one-way locking assembly 8 is installed on the outside of the flip support assembly 5.

[0030] like Figure 4 and Figure 5 As shown, the flip support assembly 5 includes a flip plate 51 installed at the bottom end of the power supply housing 1 through a hinge, an arc-shaped rack 52 is fixedly installed on one end face of the flip plate 51, and the arc-shaped rack 52 is slidably connected to the inside of the power supply housing 1. Support columns 53 are symmetrically welded on the bottom end of the flip plate 51. The distance between the closest point of the support column 53 to the front of the power supply housing 1 and the flip line of the flip plate 51 is greater than the distance between the flip line of the flip plate 51 and the front of the power supply housing 1. An anti-slip pad 54 is sleeved on the bottom end of the support column 53. There is a 1 cm gap between one end of the flip plate 51 and the inner wall of the power supply housing 1, and grooves are equidistantly provided on one end face of the flip plate 51.

[0031] By rotating the flip plate 51, the flip plate 51 drives the arc-shaped rack 52 to enter the interior of the power supply housing 1, and at the same time drives the support column 53 and the anti-slip pad 54 to flip. When the flip plate 51 flips more than ninety degrees, the support column 53 and the flip plate 51 flip synchronously. When the flip plate 51 flips, it supports the power supply housing 1, so that a triangular support is formed between the power supply housing 1 and the desktop, thereby changing the angle of the power supply housing 1, and flipping the second flip plate 51 at the same time. The angle and height of the power supply housing 1 can be adjusted through the two flip plates 51 to change the difficulty of adjustment.

[0032] like Figure 4 and Figure 6As shown, the height adjustment moving assembly 6 includes a lifting plate 61 which is vertically slidably connected to the inside of the flip plate 51, a ball bearing 62 is embedded and installed on the top of the lifting plate 61, a positioning rod 63 is embedded and installed on one side of the bottom end of the lifting plate 61, and the bottom end of the positioning rod 63 is rotatably connected to a rotating sleeve 64, and an external threaded column 65 is fixedly installed on the bottom end of the rotating sleeve 64, and a driving disk 66 is fixedly installed on the bottom end of the external threaded column 65. A column 67 is symmetrically embedded and installed on the other side of the bottom end of the lifting plate 61, and the column 67 is vertically slidably connected to the inside of the flip plate 51, and a T-slot is opened inside the support column 53 to facilitate the placement of the external threaded column 65 and the driving disk 66 to change the placement difficulty. The external threaded column 65 and the support column 53 are connected by threads, and the bottom end of the driving disk 66 is symmetrically opened with placement grooves to facilitate the adjustment of the position of the external threaded column 65 to change the adjustment difficulty of the position of the external threaded column 65;

[0033] When the flip plate 51 rotates 180 degrees, the top of the flip plate 51 fits with the bottom of the power supply casing 1, and at this time the bottom of the flip plate 51 fits with the ground, and then the person rotates the drive disk 66, and the drive disk 66 drives the external threaded column 65 to rotate. When the external threaded column 65 rotates, it moves along the inside of the support column 53, and at the same time drives the rotating sleeve 64 to rotate on the outside of the positioning rod 63. At this time, the external threaded column 65 drives the positioning rod 63 to move when it moves along the inside of the external threaded column 65, and the positioning rod 63 moves when it moves, so that the lifting plate 61 moves, and the lifting plate 61 moves when it moves, and the lifting plate 61 drives the ball 62 to fit with the desktop, and when it continues to move, because the bottom end is blocked by the desktop, the power supply casing 1 is driven to rise, so that when the height between the power supply casing 1 and the desktop is adjusted, the friction between the power supply casing 1 and the desktop can be changed, thereby facilitating the adjustment of the position of the power supply casing 1.

[0034] like Figure 4 and Figure 7 As shown, the one-way locking assembly 8 includes a spring rod 81 fixedly installed at the bottom end of the inner wall of the power supply housing 1, and a concave rod 82 is clamped and installed at one end of the spring rod 81. A one-way bearing 83 is installed inside the concave rod 82 through interference fit, and the same gear ring 84 is installed between the two one-way bearings 83 through interference fit. The center point of the arc-shaped rack 52 and the flip point of the flip plate 51 are on the same straight line. An arc-shaped groove is opened inside the power supply housing 1, and the width of the arc-shaped groove is greater than the thickness of the arc-shaped rack 52. It is used for placing the arc-shaped rack 52, which changes the difficulty of placing the arc-shaped rack 52. The outer side of the gear ring 84 and the outer side of the arc-shaped rack 52 are meshed with each other, which is convenient for the gear ring 84 to limit the arc-shaped rack 52, so that the arc-shaped rack 52 cannot rotate. A connecting frame 85 is integrally formed on one end surface of the concave rod 82;

[0035] When the flip plate 51 flips over more than ninety degrees, the power supply housing 1 applies pressure to the flip plate 51. When the flip plate 51 cannot be limited, the flip plate 51 rotates from ninety degrees to one hundred and eighty degrees. In this process, by loosening the connecting frame 85, the concave rod 82 is driven to move under the action of the contraction force of the spring rod 81. When the concave rod 82 moves, the one-way bearing 83 drives the gear ring 84 to engage with the arc-shaped rack 52, so that the gear ring 84 fixes the arc-shaped rack 52 to prevent the flip plate 51 from rotating from ninety degrees to one hundred and eighty degrees.

[0036] like Figure 3 and Figure 7 As shown, the number of spring rods 81 is set to two, the number ratio of the spring rods 81 to the concave rods 82 is two to one, and the distance between the center line of the concave rod 82 and the bottom end of the power supply housing 1 is greater than the maximum diameter of the gear ring 84;

[0037] It can facilitate the horizontal movement of the concave rod 82, change the difficulty of horizontal movement of the concave rod 82, and because the distance between the center line of the concave rod 82 and the bottom end of the power supply housing 1 is greater than the maximum diameter of the gear ring 84, the horizontal movement of the concave rod 82 will not cause the device to be unable to operate due to the obstruction of the gear ring 84.

[0038] like Figure 3 and Figure 8 As shown, a conductive grounding component 7 is fixedly installed inside the power supply housing 1, and the conductive grounding component 7 includes a conductive grid 71 fixedly installed at the bottom end of the inner wall of the power supply housing 1, and a conductive sleeve 72 is fixedly installed at the bottom end of the conductive grid 71 at an equal distance, and a conductive block 73 is slidably connected inside the conductive sleeve 72, and a terminal 74 is fixedly installed at the bottom end of the conductive block 73. A through hole is provided at the bottom of the outer surface of the terminal 74, and an insulating block 75 is fixedly installed at the bottom end of the terminal 74. A guide groove that fits the conductive block 73 is provided inside the conductive sleeve 72 for connection with the grounding wire, which changes the difficulty of installing the grounding wire.

[0039] Since the flip plate 51 does not support the insulating block 75 after flipping, the gravity of the insulating block 75 and the terminal 74 drives the conductive block 73 to move inside the conductive sleeve 72, and then connects the terminal 74 to the ground wire, so that the power supply housing 1 is powered, thereby increasing the safety of the power supply housing 1 when in use.

[0040] Working principle: During actual use of the device, the connecting frame 85 is pulled, and when the connecting frame 85 moves, the concave rod 82 is driven to move, and when the concave rod 82 moves, the spring rod 81 is compressed. At this time, when the concave rod 82 moves, the gear ring 84 is driven to separate from the arc-shaped rack 52 through the one-way bearing 83, and then the flip plate 51 is rotated, and the flip plate 51 drives the arc-shaped rack 52 to enter the power supply housing 1, and at this time, the support column 53 and the anti-slip pad 54 are driven to flip synchronously. When the flip plate 51 flips more than ninety degrees, the support column 53 and the flip plate 51 are flipped synchronously, and the flip plate 51 supports the power supply housing 1 when it flips, so that a triangular support is formed between the power supply housing 1 and the desktop, and then the connecting frame 85 is loosened. At this time, the concave rod 82 is driven to move under the action of the contraction force of the spring rod 81, and the concave When the rod 82 moves, the one-way bearing 83 drives the gear ring 84 to mesh with the arc-shaped rack 52, so that the gear ring 84 fixes the arc-shaped rack 52 to prevent the flip plate 51 from rotating from 90 degrees to 180 degrees, and the two flip plates 51 are flipped in turn to form an outward eight-shaped shape, and the angle and height of the power supply housing 1 are adjusted by changing the different inclination angles of the two flip plates 51. A triangular support is formed between the two flip plates 51 and the desktop, so that the power supply housing 1 is more stable during use and not easy to tip over, and the angle and height of the power supply housing 1 can be easily controlled to adapt to different usage scenarios and needs, and adjusting the height can make the operator more comfortable to perform experimental operations and avoid bending over or maintaining a bad posture for a long time;

[0041] In the above process, the insulating block 75 is not supported after the flip plate 51 flips. At this time, the gravity of the insulating block 75 and the terminal 74 drives the conductive block 73 to move inside the conductive sleeve 72, and then the terminal 74 is connected to the grounding wire, so that the power supply housing 1 is powered, thereby increasing the safety of the power supply housing 1 when in use. Connecting the power supply housing 1 to the ground terminal through the grounding wire can provide a safe path for current leakage, and quickly flow the current to the ground, thereby reducing the risk of electric shock to the user, and can also protect other electronic equipment from electric shock. When a power failure causes current leakage, the grounding wire can leak the current to the ground, avoiding the problem of current passing through the connected device and causing damage to the device;

[0042] Then, according to the above operation, the flip plate 51 is adjusted 180 degrees, and the top of the flip plate 51 is in contact with the bottom of the power supply housing 1, and at this time, the bottom of the flip plate 51 is in contact with the ground, and then the personnel rotates the driving disk 66, and the driving disk 66 drives the external threaded column 65 to rotate. When the external threaded column 65 rotates, it moves along the inside of the support column 53, and at the same time drives the rotating sleeve 64 to rotate on the outside of the positioning rod 63, and at this time, the positioning rod 63 is driven to move during movement, and the positioning rod 63 drives the lifting plate 61 to move when the positioning rod 63 moves, so that when the lifting plate 61 moves, it drives the ball 62 to fit with the desktop, and then continues to move, so that the power supply housing 1 is driven to rise, so that when the height between the power supply housing 1 and the desktop is adjusted, the friction between the power supply housing 1 and the desktop can be changed, so as to facilitate the adjustment of the position of the power supply housing 1, and through the lifting function, the height between the power supply housing 1 and the desktop can be flexibly adjusted, and the friction between the power supply housing 1 and the desktop can be changed, so that the position of the power supply housing 1 is more flexible and convenient to adjust to the optimal position.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
