Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a multi-axis frequency converter buckle. Background Art

[0002] The birth of the frequency converter stems from the demand for stepless speed regulation of AC motors. With the emergence of components such as thyristors, static induction transistors, and high-voltage insulated gate bipolar thyristors, electrical technology has undergone rapid changes, and frequency converter speed regulation technology has also developed accordingly. During the use of the frequency converter, it is necessary to install and fix the upper module and the base with snap fasteners.

[0003] However, the existing buckles still have the following technical problems when used:

[0004] At present, the upper module and the base of the inverter are generally fixed by screw locking. If the screws are driven from the upper module to the base, although it is convenient to disassemble when replacing the upper module, the position of the fixing screws must exceed the boundary of the upper module, and the volume of the entire servo motor module becomes larger; if the screws are driven from the base to the upper module, although the volume of the module can be reduced, the base is fixed to the fixed surface. If the upper module needs to be replaced, the entire module and the fixed surface need to be disassembled together, which is very troublesome.

[0005] Therefore, a multi-axis frequency converter buckle is proposed to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the present invention is to provide a multi-axis inverter buckle to solve the problems raised in the above background technology.

[0008] Preferably, the teardrop-shaped limiting block and the teardrop-shaped limiting groove are adapted to each other and are in contact with each other.

[0011] Preferably, the left side of the limiting step is arc-shaped, and the limiting step is adapted to the slot.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] This application uses the connection between the teardrop-shaped limit block and the teardrop-shaped limit groove as the rotation fulcrum, so that the base and the upper mold group can be rotatably connected. After the base and the upper mold group are engaged with each other, the buckle is engaged with the card rod, and the limit step is engaged with the card slot, thereby realizing the connection and fixation between the base and the upper mold group.

[0023] A multi-axis frequency converter buckle comprises a base 1 and an upper module 2, the upper module 2 is arranged at the upper end of the base 1, a teardrop-shaped limit block 3 is fixed to the left end of the upper side of the base 1, a teardrop-shaped limit groove 4 is provided at the lower end of the left side of the upper module 2, the teardrop-shaped limit block 3 is clamped in the inside of the teardrop-shaped limit groove 4, the right end of the upper side of the base 1 is provided with a buckle 5 through a shaft pin, the left side of the buckle 5 is fixedly connected to the limit step 6, the right end of the front and rear sides of the upper module 2 are fixed with a clamping rod 7 at the corresponding buckle 5, a clamping slot is provided on the right side of the upper module 2, the buckle 5 is clamped with two clamping rods 7, the limit step 6 is clamped with the slot, and the teardrop-shaped limit of the base 1 is clamped. The block 3 fits in with the contoured surface corresponding to the teardrop-shaped limiting groove 4 on the side wall of the upper module. Taking this as the starting point, rotate the base 1 so that the base 1 slowly fits in with the upper module 2 and completes the plug-in insertion. The two insertion rods 8 are also inserted into the sockets. After the base 1 is completely fitted with the upper module 2, finally rotate the buckle 5 connected to the base 1 so that the two clips of the buckle 5 are engaged with the card rod 7 to complete the fixation. When the upper module 2 needs to be replaced, press the buckle 5 directly to separate the buckle 5 from the card rod 7, and the limiting step 6 from the card slot. Finally, separate the teardrop-shaped limiting block 3 from the teardrop-shaped limiting groove 4, so that the upper module 2 can be quickly disassembled and replaced.

[0024] The teardrop-shaped limiting block 3 is adapted to the teardrop-shaped limiting groove 4 and contacts each other. The rotation of the base 1 and the upper mold assembly 2 will rotate with the connection between the teardrop-shaped limiting block 3 and the teardrop-shaped limiting groove 4 as the fulcrum.

[0025] Symmetrical insertion rods 8 are fixed to the front and rear ends of the upper side of the base 1. Insertion holes are opened on the lower side wall of the upper module 2 corresponding to the positions of the insertion rods 8, and the insertion rods 8 are plugged into the insertion holes.

[0026] The side wall of the buckle 5 is provided with an arc-shaped slot, which is matched with the clamping rod 7 .

[0027] The left side of the limiting step 6 is arc-shaped, and the limiting step 6 is adapted to the card slot. Not only can the limiting step 6 be engaged with the card slot when subjected to force, but it is also easy to disassemble.

[0028] Working principle:

[0029] First, the teardrop-shaped limit block 3 is clamped with the teardrop-shaped limit groove 4, and the base 1 and the upper mold group 2 can rotate with the connection between the teardrop-shaped limit block 3 and the teardrop-shaped limit groove 4 as the fulcrum. After the base 1 is clamped with the lower end of the upper mold group 2, the buckle 5 is clamped with the clamping rod 7, and the limit step 6 is clamped with the clamping groove, thereby realizing the installation and fixation between the base 1 and the upper mold group 2, and the operation is very convenient, and the base 1 and the upper mold group 2 are also easy to disassemble.
