[0012] Preferably, the method for using the power distribution cabinet wiring harness terminal fixing device comprises the following steps:

[0013] S1: The staff first installs the installation ring on the outside of the distribution line near its insertion end, and then inserts the end of the distribution line into the slot by holding the distribution line. During the insertion process, the installation ring is pressed against the side end of the L-shaped trigger block, so that the L-shaped trigger block drives the trigger tooth groove rod to slide at the bottom of the mounting frame, thereby driving the trigger gear meshed with it to rotate, so that the first bevel gear rotates synchronously, and then drives the second bevel gear meshed with it to drive the gear plate to rotate synchronously on the synchronous plate, so that several synchronous gears rotate synchronously, and then drives several driving tooth groove rods meshed with it to synchronously move toward the center of the synchronous plate under the action of the limit plate. Through the provided connecting block, several clamping brackets are all moved closer to the outside of the insertion end of the distribution line, and in the process of moving the trigger tooth groove rod, the connecting rod is squeezed to slide in the connecting sleeve, and the compression spring is contracted. When the trigger tooth groove rod stops moving, the end of the sliding rod can be embedded in the bayonet, thereby fixing the position of the trigger tooth groove rod;

[0014] S2: When the mounting ring is pressed against the side end of the L-shaped trigger block and it is moved, the end of the locking rod located on the outside of the operating box and away from the side of the mounting frame is manually pushed to drive the L-shaped limit plate and the semi-arc pressure plate to move synchronously in the direction of the mounting frame, and in the process of moving, the limit groove cooperates with the clamping column, thereby driving the pressing sleeve to slide upward in the through-hole until the end of the locking column is embedded in the corresponding lock hole under the action of the arc pressure plate and the return spring. At this time, the locking rod squeezes the L-shaped connecting rod and drives the pressing shaft to move in the direction of the reference seat, and drives the linkage sleeve to rotate on the reference seat through the cooperation of the arc slide groove and the connecting rod, and then drives the locking disk to rotate, and drives a plurality of locking blocks to synchronously move away from the center of the locking disk by controlling the cooperation of the arc slide groove and the control rod, and then drives a plurality of clamping blocks to be clamped at the tooth groove end of a synchronous gear respectively;

[0015] S3: When the end of the locking rod squeezes the L-shaped connecting rod and causes the linkage sleeve to rotate, the unlocking shaft and the unlocking disk are driven to rotate synchronously through the transmission leather, and then the spring telescopic rod is driven to rotate around the unlocking disk, so that the telescopic end of the spring telescopic rod contacts the oblique side of the passive resistance rod, and then the spring telescopic rod is contracted. At this time, the distribution line is in a locked state. When the distribution line needs to be unlocked, the two arc-shaped pressure plates are controlled to approach each other, and then the two locking columns are driven to disengage from the locking holes respectively, and the pressing sleeve is pressed down. With the cooperation of the clamping column and the limit groove, the locking rod is driven to move in the direction away from the mounting frame, so that the end of the locking rod is disengaged from the L-shaped connecting rod. At this time, the linkage sleeve rotates and resets under the action of the coil spring. , so that each block is away from the synchronous gear, thereby driving the synchronous disk to rotate and reset, and the synchronous rotation of the locking disk drives the spring telescopic rod to press toward the side of the top of the passive resistance rod that is not obliquely set, thereby driving the sliding rod to slide away from the bayonet in the sliding sleeve, so that the sliding rod is away from the bayonet, and the connecting rod is reset in the connecting sleeve under the action of the compression spring, so that the trigger tooth groove rod is reset, and then a plurality of clamping brackets are moved away from the four sides of the distribution line, thereby releasing the fixation, and after the locking disk continues to rotate, the spring telescopic rod shrinks under continuous pressure, so that it loses contact with the passive resistance rod, and the passive resistance rod is reset under the action of the telescopic spring and the sliding rod is re-set in a bayonet, thereby facilitating the next installation of the distribution line;

[0016] S4: When the locking rod is controlled to move toward the mounting frame, the two arc-shaped pressure plates are synchronously driven to move, thereby pressing against one side of the bottom of several L-shaped cleaning frames, causing them to rotate on the rotating frame, and causing the bottom of the cleaning piece to contact and stay on the outside of the distribution line. When the locking rod is reset by controlling the pressing sleeve, the two arc-shaped pressure plates are driven away from the L-shaped cleaning frame, causing the L-shaped cleaning frame to reset under the action of the coil spring, and during the resetting process, the outside of the distribution line is cleaned by the cleaning piece.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In the present invention, when the device is used, the staff first installs the installation component to the outside of the distribution line, and then inserts the end of the distribution line into the slot by holding the distribution line. During the insertion process, the installation component abuts against the side end of the trigger component, so that after the distribution line is installed in the slot, the distribution line is limited and fixed around one end of the distribution line close to the slot, and the position of the distribution line is further locked by controlling the installation component to work, and when the installation component releases the control of the linkage component, the cleaning component is triggered to make the cleaning ends of several cleaning components clean the surface of the distribution line located on the outside of the slot, so as to facilitate the staff to manually disassemble the distribution line. In this process, the installation of the distribution line by the staff is simplified, and the fixing and unlocking of the distribution line can be completed in one step, which improves the convenience in work. At the same time, it avoids the distribution line after a long period of use. The surface of the distribution line located on the outside of the slot is attached with a large amount of dust, which is not conducive to the operation of the staff, thereby further improving the practicality of the device, so that the distribution line can be quickly installed and disassembled, and the surface outside the distribution line position can be automatically cleaned before disassembly, so as to avoid the effect of low convenience and insufficient practicality.

[0019] In the present invention, the staff first installs the installation ring on the outside of the distribution line near its insertion end, and then inserts the end of the distribution line into the slot by holding the distribution line. During the insertion process, the installation ring is pressed against the side end of the L-shaped trigger block, so that the L-shaped trigger block drives the trigger tooth groove rod to slide at the bottom of the installation frame, so that a plurality of clamping brackets are all close to the outside of the insertion end of the distribution line, thereby limiting and fixing the distribution line around one end of the slot, so that the distribution line can be initially fixed after installation is completed, thereby improving convenience during use.

[0020] In the present invention, when the mounting ring is pressed against the side end of the L-shaped trigger block and the block is moved, the end of the locking rod located on the outside of the operating box and away from the mounting frame is manually pushed. At this time, the locking rod squeezes the L-shaped connecting rod and drives the pressure shaft to move in the direction of the reference seat. Through the cooperation of the arc-shaped slide groove and the connecting rod, the linkage sleeve is driven to rotate on the reference seat, and then a plurality of clamping blocks are respectively clamped at the tooth groove end of a synchronous gear, thereby further locking the positions of a plurality of clamping brackets, thereby further fixing the position of the installed distribution line, and improving the stability of the device during use.

[0021] In the present invention, when it is necessary to unlock the distribution line, the linkage sleeve rotates and resets under the action of the coil spring, so that each block is away from the synchronous gear, thereby driving the synchronous disk to rotate and reset, and the locking disk rotates synchronously to drive the spring telescopic rod to press toward the side of the top of the passive resistance rod that is not obliquely set, thereby driving the sliding rod away from the bayonet, and the connecting rod is reset in the connecting sleeve under the action of the compression spring, so that the trigger tooth groove rod is reset, and then a plurality of clamping brackets are moved away from the four sides of the distribution line, thereby releasing the fixation, and making it convenient for the staff to manually disassemble the distribution line. In this process, the installation of the distribution line by the staff is simplified, and the fixing and unlocking of the distribution line can be completed in one step, thereby improving the convenience in work.

[0022] In the present invention, when the locking rod is controlled to move in the direction of the mounting frame, the two arc-shaped pressure plates are synchronously driven to move, so that the bottom of the cleaning piece contacts and stays on the outside of the distribution line, thereby facilitating the shielding of dust and preventing dust from falling to the connection between the distribution line and the slot during long-term use of the distribution line, thereby affecting the operation of the distribution line; when the locking rod is reset by controlling the pressing sleeve, the two arc-shaped pressure plates are driven away from the L-shaped cleaning frame, so that the L-shaped cleaning frame is reset under the action of the coil spring; and during the resetting process, the outside of the distribution line is cleaned by the cleaning piece, and the dust attached to the surface of the distribution line outside the slot is cleaned, which is then convenient for manual operation by the staff, thereby further improving the practicability of the device.
