Description

Technical Field

[0001] This utility model relates to the field of motor forward / reverse phase converter technology, and in particular to a motor forward / reverse phase converter with a long service life. Background Technology

[0002] Electric motors are commonly used power devices. Some equipment is frequently moved during use, and the motor must rotate in the forward direction according to the equipment's operating conditions. If the motor rotates in reverse, adjustments are needed. During the adjustment process (for example, in construction, vibratory rods are frequently moved, requiring frequent wiring and disconnection, which can cause the motor to burn out), bearings are designed and operate according to specific force patterns and rotation directions when the vibratory rod is working normally in the forward direction. When rotating in reverse, the contact force direction between the balls or rollers inside the bearing and the inner and outer rings changes, leading to uneven force distribution.

[0003] This can cause additional vibration and heat in the bearing, accelerating bearing wear and leading to fatigue spalling, wear pits, and other problems on the surface of the balls or rollers, ultimately resulting in bearing damage. This can affect the normal operation of the vibrator, easily damage the switch terminals in the distribution box, prevent the wires from being clamped, and cause the motor to burn out. When using a three-phase four-wire socket for wiring, if the motor reverses, it is necessary to disassemble the plug and perform other procedures when reversing the phase wires, which is labor-intensive and time-consuming. In addition, the electrode contacts generate an electric arc during the rotation and reversal process, which generates high temperatures and can easily damage the mounting base or housing, leading to a reduction in service life or creating safety hazards. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a motor forward and reverse phase converter with a long service life. It overcomes the shortcomings of the prior art and effectively solves the problems of disassembling the plug and other processes when reversing the motor to change the phase line, which is labor-intensive, time-consuming, and reduces the service life or causes safety hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A long-life motor forward / reverse phase converter includes a lower end sleeve and an upper top cover. The lower end sleeve and the upper top cover are provided with internal wiring components, which include a base support, a sleeve, a top plate, a terminal block, and a spring. The base support is located inside the lower end sleeve, the sleeve is fixedly connected to the top outer wall of the lower end sleeve, the top plate is fixedly connected to the top outer wall of the sleeve, the terminal block is slidably connected to the inner wall of the sleeve, and the spring is sleeved on the outer wall of the terminal block.

[0007] Preferably, a transverse retaining plate is slidably connected to the bottom of one side of the outer wall of the upper top cover, and a latch is hinged to one side of the outer wall of the lower end sleeve, with the latch tightly attached to the outer wall of the transverse retaining plate.

[0008] Preferably, the interiors of the two sleeves are respectively provided with a hollow fixing lock pin and a solid fixing lock pin.

[0009] Preferably, a first screw is fixedly connected to the top of the outer wall on one side of the terminal block.

[0010] Preferably, the top outer wall of the top plate is provided with a fixing frame, and the first screw is located inside the fixing frame.

[0011] Preferably, the top of the lower end sleeve is provided with symmetrically distributed guide plates, and the upper top cover is slidably connected to the outer wall of the guide plates, and a second screw is fixedly connected to the inner wall of the guide plates.

[0012] Preferably, the bottom of the outer walls on both sides of the upper top cover is provided with an arc-shaped groove, and the second screw is located inside the arc-shaped groove.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This design features a long-life motor forward / reverse phase converter. When the top cover rotates, the internal contact points connect with different contacts as the top rotates. This change in state leads to a change in the circuit connection method, thereby achieving phase wire interchange. Since phase switching is achieved through rotation, there is no need to rewire or replace the socket, thus achieving the conversion of motor forward and reverse rotation. This enables quick adjustment of motor forward and reverse rotation, improving work efficiency and saving time.

[0015] 2. This design features a long-life motor forward / reverse phase converter. Improvements have been made to the lower end sleeve and upper top cover, resulting in a housing with high-temperature resistance and explosion-proof structure. This prevents the electrode contacts from generating electric arcs due to high temperatures during rotation and reversal, thereby increasing the safety performance of the motor forward / reverse phase converter and extending its service life.
