DETAILED DESCRIPTION

[0024] The present invention is further described in detail below in conjunction with the embodiments:

[0025] like Figure 1-5As shown in the figure, the utility model provides a high-voltage frequency converter convenient for movement, which includes a base 1. Four corners at the lower end of the base 1 are symmetrically and fixedly installed with supporting feet 2. A fixing mechanism 3 is installed at the upper end of the base 1. A high-voltage frequency converter 4 is movably installed in the middle of the upper end of the base 1. A moving mechanism 5 is installed inside the lower end of the base 1. A controller 6 is fixedly installed on the right side of the front end of the base 1. A protective cover 7 is fixedly installed at the right end of the base 1. The fixing mechanism 3 includes a groove 31. The groove 31 is opened in the middle of the upper end of the base 1. A bidirectional screw 32 is rotatably connected inside the groove 31. Both sides of the bidirectional screw 32 are threadedly connected with moving seats 33. A receiving plate 34 is fixedly installed at the upper end of the moving seat 33. A clamping plate 35 is fixedly installed at the upper end of the receiving plate 34. Guide grooves 36 are symmetrically opened on both the front and rear sides of the upper end of the base 1. Guide blocks 37 are slidably connected inside the guide grooves 36. A motor 38 is fixedly installed at the left end of the base 1.

[0026] The controller 6 is electrically connected to the motor 38 and the motor 515.

[0027] The protective cover 7 is located outside the motor 515. The rear side of the inner cavity of the protective cover 7 is fixedly installed with the bottom end of the motor 515.

[0028] The base 1 can be supported by the provided supporting feet 2, and the motor 515, the driving sprocket 512, the driving sprocket 512 and the chain 514 can be protected by the provided protective cover 7.

[0029] As Figure 3 shown, the top end of the bidirectional screw 32 is in transmission connection with the output end of the motor 38.

[0030] The upper ends of the guide blocks 37 and both sides of the lower end of the clamping plate 35 are symmetrically and fixedly installed. The clamping plate 35 is in a "C" shape.

[0031] By providing the rubber anti-slip pads, the friction force of the clamping plate 35 on the high-voltage frequency converter 4 can be increased, so that its fixing effect is improved. At the same time, it can also prevent the clamping plate 35 from causing clamping marks on the outer wall of the high-voltage frequency converter 4. When the two groups of clamping plates 35 move, they will drive the guide blocks 37 to move synchronously in the guide grooves 36, thereby improving the stability of the movement of the clamping plate 35.

[0032] As Figure 4-5As shown, the moving mechanism 5 includes a receiving groove 51, and the receiving grooves 51 are symmetrically opened on both sides of the lower end of the base 1. The upper end of the inner cavity of the receiving groove 51 is rotatably connected with a bidirectional screw 32, and both sides of the bidirectional screw 32 are threadedly connected with a threaded seat 53, and the lower end of the threaded seat 53 is fixedly installed with an articulated seat 1 54, and the inner side of the articulated seat 1 54 is rotatably connected with a connecting plate 55, and the lower end of the connecting plate 55 is rotatably connected with a mounting seat 56, and the lower end of the mounting seat 56 is fixedly installed with a lifting plate 57, and the lower end of the lifting plate 57 is symmetrically fixedly installed on both sides. There are moving wheels 58, and limit blocks 59 are symmetrically fixed on the left and right sides of the lifting plate 57. Limit grooves 510 are symmetrically opened on the left and right inner walls of the storage groove 51. Through holes 511 are symmetrically opened on the two side surfaces of the lower end of the base 1. A transmission sprocket 512 is rotatably connected to the front side of the right end of the base 1, and a driven sprocket 513 is rotatably connected to the rear side of the right end of the base 1. The outer parts of the transmission sprocket 512 and the driven sprocket 513 are connected with meshing chains 514, and a motor 2 515 is fixedly installed at the front end of the transmission sprocket 512.

[0033] The lifting plate 57 is movably installed inside the storage groove 51, and the limiting block 59 matches the limiting groove 510 and is slidably connected.

[0034] The through hole 511 is located directly below the moving wheel 58 , and the rear ends of the driving sprocket 512 and the driven sprocket 513 are both drivingly connected to the tops of the two sets of bidirectional screw rods 52 .

[0035] By gradually moving the two sets of threaded seats 53 away from each other, the lifting plate 57 can be driven to rise, thereby driving the moving wheel 58 to be retracted into the storage groove 51, so that the support leg 2 is in contact with the ground, which is convenient for supporting the base 1. At the same time, when the lifting plate 57 moves up and down, it will drive the limit block 59 to slide synchronously in the limit groove 510, thereby improving the stability of the lifting plate 57 when moving. At the same time, a transmission structure can be formed by the transmission sprocket 512, the driven sprocket 513 and the chain 514, and the transmission structure can be used to ensure the simultaneous rotation of the two sets of bidirectional screw rods 52.

[0036] The following is a detailed description of the working principle of this portable high-voltage inverter.

[0037] like Figure 1-5As shown, when the high-voltage inverter 4 that is easy to move is used and needs to be transported, the high-voltage inverter 4 can be placed on the base 1 first, and then the motor 38 is started to drive the bidirectional screw 32 to rotate, so that the bidirectional screw 32 drives the moving seat 33 connected by threads on both sides to move synchronously, so that the moving seat 33 drives the clamping plates 35 on both sides to move toward the high-voltage inverter 4 through the receiving plate 34, so that the clamping plates 35 can contact the two sides of the lower end of the high-voltage inverter 4. The second motor 515 is started, and the second motor 515 drives the transmission sprocket 512 to rotate, so that the transmission sprocket 512 drives the driven sprocket 513 to rotate synchronously through the chain 514, and then the two sets of bidirectional screw rods 52 can be driven to move synchronously, so that the two sets of bidirectional screw rods 52 drive the threaded seats 53 connected by threads on both sides to gradually approach each other, so that the threaded seats 53 push the lifting plate 57 downward through the hinge seat 1 54 and the connecting plate 55 during the movement, so that the lifting plate 57 moves downward, so that the lifting plate 57 drives the moving wheel 58 to move synchronously, so that the moving wheel 58 passes through the through hole 511 and contacts the ground, and at the same time, with the rotation of the bidirectional screw rod 52, the base 1 and the high-voltage frequency converter 4 can be lifted, so that the high-voltage frequency converter 4 can be conveniently moved and transported, thereby improving the use effect of the device.

[0038] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
