[0014] 1. In the present invention, when it is necessary to install the sealing plate, first place the sealing plate into the junction box. When the top of the sealing plate is flush with the top of the connecting column, the connecting frame at the bottom of the sealing plate will be flush with the plug-in block. At this time, pull the cylinder upward first, and the cylinder will drive the rectangular block on its surface to rise. At the same time, the cylinder will pull the insert out of the slot through the long plate. At this time, the insert will no longer be restricted by the slot for the rotation of the cylinder. At this time, rotate the cylinder, and the cylinder will drive the rotating block to rotate through the rectangular block. At this time, the rotating block will rotate in the connecting column. Since a part of the rotating block is protruding at one end close to the insert block, the rotating block will squeeze the insert block, thereby squeezing the insert block out of the connecting column and inserting it into the connecting frame. At this time, the sealing plate will be restricted from moving up and down by the connecting frame. At this time, press the cylinder toward the rotating block, and the cylinder will drive the long plate on its surface to move. At this time, the long plate will drive the insert to be inserted into the slot on the inner wall of the connecting column. At this time, the insert will The block is then moved out of the way when the cylinder is rotated, and the movement of the connecting frame is no longer restricted by the rotating block, and the sealing plate can be opened. The whole structure solves the problem that the existing junction box often needs to use bolts to install the sealing plate after the wires are installed, and when the motor is just produced and debugged, the user's time is greatly wasted due to the frequent installation and removal of the sealing cover.

[0015] 2. In the present invention, first press the disc and the slide rod toward the direction of the chassis, then a part of the top of the long column will be exposed, then the wire is wound around the surface of the long column, and when the wire is wound, release the disc and the slide rod, then the disc will be pushed by the spring on the surface of the chassis to approach the sealing plate, and the slide rod will also be pushed by the spring at the top of the long rod to approach the sealing plate, and at the same time, slide the long rod, slide the long rod toward the direction of the long column, then the long rod and the slide rod will squeeze the wire, thereby preventing the wire from spreading. When the long rod and the slide rod squeeze the wire At this time, the long rod will also squeeze the spring on its own surface at the same time. When the round bar is rotated, the round bar will drive the limit block on its surface to rotate. At this time, the limit block will be misaligned with the connecting groove. At this time, the limit block will press against the long rod. At the same time, since the long rod is pushed by the wire and the spring, it will give the limit block a lateral thrust, thereby increasing the friction between the long rod and the limit block, avoiding the problem of the limit block sliding easily. The whole structure solves the problem that when the wire is too long, if there is no tool at hand, it will be messy if it is placed directly in the junction box.

[0016] 3. In the present invention, when the motor needs to be moved, the block is first rotated out of the groove, and then the two connecting blocks are respectively inserted into the two blocks, and the insertion rod is tightened at the same time.

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Example 1, as Figure 1-7 As shown, the present invention provides an induction motor for leakage protection, including a tail housing 1, a cooling fan 2, a plastic housing 3, a stator 4, an end cover 5 and a rotating shaft 6.

[0028] like Figure 1 and Figure 3As shown, the open end of the tail shell 1 is fixedly installed with the plastic shell 3, and a cooling fan 2 is installed inside the plastic shell 3. A stator 4 is fixedly installed inside the plastic shell 3, and a rotating shaft 6 is movably connected inside the stator 4. An end cover 5 is fixedly installed on the end of the plastic shell 3 away from the tail shell 1, and an insulating layer is provided on the surface of the rotating shaft 6 to increase insulation. A junction box 7 is fixedly installed on the surface of the plastic shell 3, and a sealing plate 8 is movably connected to the inner wall of the junction box 7. A connecting column 9 is fixedly connected to the inner wall of the junction box 7. The sealing plate 8 slides with the junction box 7 through the connecting column 9, and the bottom end of the sealing plate 8 is fixedly connected to a connecting frame 13. An insert 10 is inserted into the interior of the connecting column 9 for sliding. The insert 10 is in the shape of the letter "L", and the short arm end of the "L"-shaped insert 10 is fixedly connected to a spring. The inner wall is rotatably connected with a rotating block 11, and the end of the spring away from the rotating block 11 is fixedly connected to the inner wall of the connecting column 9. When the sealing plate 8 needs to be installed, the sealing plate 8 is first placed in the junction box 7. When the top of the sealing plate 8 is flush with the top of the connecting column 9, the connecting frame 13 at the bottom of the sealing plate 8 will be flush with the plug-in block 10. At this time, pull the cylinder 12 upward first. The cylinder 12 will drive the rectangular block 14 on its surface to rise. At the same time, the cylinder 12 will pull the insertion strip 16 out of the slot through the long plate 15. At this time, the insertion strip 16 will no longer limit the rotation of the cylinder 12 through the slot. At this time, rotate the cylinder 12. The cylinder 12 will drive the rotating block 11 to rotate through the rectangular block 14. At this time, the rotating block 11 will rotate in the connecting column 9. Since a part of the rotating block 11 protrudes near the end of the plug-in block 10, this When the rotating block 11 is turned, the plug-in block 10 will be squeezed, thereby squeezing the plug-in block 10 out of the connecting column 9 and inserting it into the connecting frame 13. At this time, the sealing plate 8 will be restricted from moving up and down by the connecting frame 13. At this time, the cylinder 12 is pressed toward the direction of the rotating block 11. The cylinder 12 will drive the long plate 15 on its surface to move. At this time, the long plate 15 will drive the insertion strip 16 to be inserted into the slot on the inner wall of the connecting column 9. At this time, the insertion strip 16 will be stuck in the slot, and at the same time, the slot will limit the rotation of the cylinder 12 through the insertion strip 16. The rectangular groove on the surface of the rotating block 11 is used to insert the rectangular block 14, so that the rotating block 11 can be driven to rotate when the cylinder 12 rotates. The internal movable insert of the rotating block 11 is provided with a cylinder 12, and the arc surface of the cylinder 12 is fixedly connected to the rectangular block 14. The surface of the rotating block 11 is opened There is a rectangular groove, the size of the rectangular groove is consistent with the size of the rectangular block 14, the rectangular groove is used to insert the rectangular block 14, the arc surface of the cylinder 12 is fixedly connected with a long plate 15, and the interior of the long plate 15 is fixedly installed with an insert 16. The inner wall of the connecting column 9 is provided with a slot for inserting the insert 16. The slot is distributed around the rotating block 11 with the cylinder 12 as the central axis. When the sealing plate 8 needs to be removed, the cylinder 12 is moved first to pull the insert 16 out of the slot. At this time, the rotating block 11 is driven to rotate by the rectangular block 14. The protruding end of the rotating block 11 will rotate in the direction away from the insert block 10. At this time, the insert block 10 will no longer be held against the rotating block 11, and the spring on the surface of the insert block 10 will restore the elastic force to push the insert block 10 in the direction away from the closure. At this time,The insert block 10 will be moved out from the interior of the connecting frame 13, thereby no longer restricting the movement of the connecting frame 13, and the sealing plate 8 can be opened.

[0029] The effect is that when the sealing plate 8 needs to be installed, the sealing plate 8 is first placed in the junction box 7. When the top of the sealing plate 8 is flush with the top of the connecting column 9, the connecting frame 13 at the bottom of the sealing plate 8 will be flush with the plug-in block 10. At this time, the cylinder 12 is pulled upwards, and the cylinder 12 will drive the rectangular block 14 on its surface to rise. At the same time, the cylinder 12 will pull the insert 16 out of the slot through the long plate 15. At this time, the insert 16 will no longer limit the rotation of the cylinder 12 through the slot. At this time, the cylinder 12 is rotated, and the cylinder 12 will pass through the rectangular block 14. The block 14 drives the rotating block 11 to rotate. At this time, the rotating block 11 will rotate in the connecting column 9. Since the rotating block 11 is close to the end of the plug 10, the rotating block 11 will squeeze the plug 10, thereby squeezing the plug 10 out of the connecting column 9 and inserting it into the connecting frame 13. At this time, the sealing plate 8 will be restricted from moving up and down by the connecting frame 13. At this time, the cylinder 12 is pressed toward the direction of the rotating block 11. The cylinder 12 will drive the long plate 15 on its surface to move. At this time, the long plate 15 will drive the insert 16 to be inserted into the inner wall of the connecting column 9 When the cover 8 needs to be removed, the cylinder 12 is first moved to pull the strip 16 out of the slot. At this time, the cover 8 is driven by the rectangular block 14 and the protruding end of the cover 11 is rotated in the direction away from the insert block 10. At this time, the insert block 10 is no longer held by the turn block 11. The spring on the surface of the insert block 10 will restore the elastic force and push the insert block 10 in the direction away from the closure. At this time, the insert block 10 will be moved out from the inside of the connecting frame 13, thereby no longer restricting the movement of the connecting frame 13. At this time, the cover 8 can be opened. The whole structure solves the problem that the existing junction box 7 often needs to use bolts to install the cover 8 after the wires are installed. When the motor is just produced and debugged, the user's time is greatly wasted by repeated installation and removal of the cover.

[0030] like Figure 1 and Figure 7As shown, the bottom end of the sealing plate 8 is fixedly connected to a long column 17, and a disc 18 is slidably sleeved on the surface of the long column 17. The bottom end of the long column 17 is fixedly connected to a chassis 19, and a spring is fixedly connected to the surface of the chassis 19. The end of the spring away from the chassis 19 is fixedly connected to the disc 18. The spring is sleeved on the surface of the long column 17. The inside of the disc 18 is slidably connected to a long rod 20. The surface of the long rod 20 is slidably sleeved with a slide rod 21. The inner wall of the slide rod 21 is fixedly connected to a spring, and the end of the spring away from the slide rod 21 is fixedly connected to the long rod 20. First, press the disc 18 and the slide bar 21 toward the bottom plate 19. At this time, a part of the top of the long column 17 will be exposed. At this time, wrap the wire around the surface of the long column 17. When the wire is wrapped, loosen the disc 18 and the slide bar 21. At this time, the disc 18 will be pushed by the spring on the surface of the bottom plate 19 to approach the sealing plate 8, and the slide bar 21 will also be pushed by the spring at the top of the long rod 20 to approach the sealing plate 8. At the same time, slide the long rod 20 and slide it toward the direction of the long column 17. At this time, the long rod 20 and the slide bar 21 will be pushed by the spring at the top of the long rod 20 to approach the sealing plate 8. 1 will squeeze the wires to prevent them from spreading. A round bar 22 is movably inserted into the interior of the long rod 20. The surface of the round bar 22 is rotatably connected to the disc 18. The arc surface of the round bar 22 is fixedly connected to the limit block 23. A connecting groove is opened at the position of the long rod 20 relative to the round bar 22. The connecting groove is used for the limit block 23 to pass through. A spring is fixedly connected to the surface of the long rod 20. The end of the spring away from the long rod 20 is fixedly connected to the disc 18. The spring is sleeved on the surface of the round bar 22. The inner diameter of the spring is larger than that of the limit block 23. When the long rod 20 and the sliding rod 21 squeeze the wire, the long rod 20 will also squeeze the spring on its own surface at the same time. At this time, the round bar 22 is rotated, and the round bar 22 will drive the limit block 23 on its surface to rotate. At this time, the limit block 23 will be misaligned with the connecting groove. At this time, the limit block 23 will press against the long rod 20. At the same time, since the long rod 20 is pushed by the wire and the spring, it gives the limit block 23 a lateral thrust, thereby increasing the friction between the long rod 20 and the limit block 23, avoiding the problem of easy sliding of the limit block 23.

[0031] The effect is that the disc 18 and the slide bar 21 are first pressed toward the direction of the chassis 19. At this time, a part of the top of the long column 17 will be exposed. At this time, the wire is wound around the surface of the long column 17. When the wire is wound, the disc 18 and the slide bar 21 are released. At this time, the disc 18 will be pushed by the spring on the surface of the chassis 19 to approach the sealing plate 8, and the slide bar 21 will also be pushed by the spring at the top of the long rod 20 to approach the sealing plate 8. At the same time, the long rod 20 is slid and slid toward the direction of the long column 17. At this time, the long rod 20 and the slide bar 21 will squeeze the wire to prevent the wire from spreading. When squeezing the wire, the long rod 20 will also squeeze the spring on its own surface. At this time, the round bar 22 is rotated, and the round bar 22 will drive the limit block 23 on its surface to rotate. At this time, the limit block 23 will be misaligned with the connecting groove. At this time, the limit block 23 will press against the long rod 20. At the same time, since the long rod 20 is pushed by the wire and the spring, it gives a lateral thrust to the limit block 23, thereby increasing the friction between the long rod 20 and the limit block 23, avoiding the problem of the limit block 23 sliding easily. The whole structure solves the problem that when the wire is too long, if there is no tool at hand, it will be messy if it is placed directly in the junction box 7.

[0032] Example 2, based on Example 1, Figure 1 and Figure 2 As shown, the surface of the plastic shell 3 is fixedly connected to the base 24, and a groove 29 is provided on the surface of the base 24. The inner wall of the groove 29 is rotatably connected to the block 25, and a connecting block 27 is movably inserted into the interior of the block 25. The surface of the connecting block 27 is rotatably connected to the handle 28. The internal thread of the block 25 is inserted with an insertion rod 26. When the motor needs to be moved, the block 25 is first rotated out of the groove 29. At this time, the two connecting blocks 27 are respectively inserted into the two blocks 25, and the insertion rod 26 is tightened at the same time. The insertion rod 26 will pass through the block 25 and be inserted into the connecting block 27. At this time, the insertion rod 26 will limit the movement of the connecting block 27. At this time, both ends of the base 24 will be equipped with handles 28, and the staff will use the handles 28 to more conveniently carry the motor. There are two handles 28, and the two handles 28 are located on both sides of the plastic shell 3.

[0033] The effect is that when the motor needs to be moved, the block 25 is first rotated out of the groove 29, and then the two connecting blocks 27 are respectively inserted into the two blocks 25, and the insertion rod 26 is tightened at the same time. The insertion rod 26 will pass through the block 25 and be inserted into the connecting block 27. At this time, the insertion rod 26 will limit the movement of the connecting block 27. At this time, handles 28 will be installed at both ends of the base 24. The staff will use the handles 28 to carry the motor more conveniently, avoiding the problem that there are sharp corners in the places that can be carried on the motor, and the workers' hands are easily hurt by the sharp corners when carrying for a long time.
