[0027] See also Figure 1The utility model provides a technical solution: a DC motor gearbox, including a box body 1, two pull rings 2 are fixedly connected to the upper surface of the box body 1, a control board 3 is installed on one side of the box body 1, a connecting shaft 4 is rotatably connected to one side of the box body 1, a connecting flange 5 is fixedly connected to the side of the box body 1 away from the connecting shaft 4, a body 6 is installed on the side of the connecting flange 5 away from the box body 1, and a limiting structure 7 is provided on one side of the box body 1 relative to the position below the connecting flange 5, so as to achieve the effect of limiting the position between the body 6 and the connecting flange 5, so as to avoid the problem that the body 6 itself is heavy and requires the cooperation of multiple personnel to reduce the work efficiency when the body 6 is replaced and maintained through the connecting flange 5. An auxiliary structure 8 is provided on the lower surface of the box body 1, which achieves the effect of assisting the movement of the box body 1, so that the box body 1 can be freely moved within a range, so as to facilitate the control and adjustment of the specific placement position of the box 1, thereby improving the maneuverability of the device.
[0028] The specific arrangement and function of the limiting structure 7 and the auxiliary structure 8 will be described in detail below.
[0029] like Figure 2 and Figure 3 As shown, the limiting structure 7 includes a connecting plate 71, one side of the connecting plate 71 is fixedly connected to the box body 1, a U-shaped rod 72 is fixedly connected to the side of the connecting plate 71 away from the box body 1, a bottom plate 73 is fixedly connected to the position below the U-shaped rod 72 on one side of the connecting plate 71, and the cross section of the bottom plate 73 is "L"-shaped, and the arc surface of the body 6 is fixedly connected to two L-shaped plates 74, and the long arms of the two L-shaped plates 74 are fixedly connected to cylinders 75, and the cylinders 75 are located between the U-shaped rod 72 and the bottom plate 73, and the long arm of the bottom plate 73 is fixedly connected to a support plate 76, a long rod 77 is slidably inserted into one side of the support plate 76, and the arc surface of the long rod 77 is slidably connected to the inner wall of the cylinder 75. The long rod 77 is inserted into the cylinder 75 through the support plate 76. The long rod 77 plays a role in temporarily fixing the cylinder 75 to prevent the body 6 from moving horizontally as much as possible. The support plate 76 is a magnet, and one end of the long rod 77 is fixedly connected to a U-shaped plate 78. One side of the U-shaped plate 78 is attracted to the magnet, and the U-shaped plate 78 is attracted to the support plate 76 through the long rod 77. The U-shaped plate 78 has the effect of limiting the long rod 77 to prevent it from separating from the cylinder 75.
[0030] like Figure 4As shown, the auxiliary structure 8 includes a fixed plate 81, the upper surface of the fixed plate 81 is fixedly connected to the box body 1, and two extension plates 82 are evenly fixedly connected on both sides of the fixed plate 81, the upper surface of the extension plate 82 is threaded with a screw 83, the upper end of the screw 83 is fixedly connected with a top ball 84, the lower end of the screw 83 is rotatably connected with a rotating plate 85, and the lower surface of the rotating plate 85 is fixedly connected with a roller 86, the arc surface of the top ball 84 is fixedly connected with an extension rod 87, and both ends of the extension rod 87 are fixedly connected with a gripping ball 88. The movable gripping ball 88 drives the screw 83 to rotate through the extension rod 87 with the help of the top ball 84, and the gripping ball 88 plays a role in facilitating the rotation of the screw 83, and the lower surface of the fixed plate 81 is evenly fixedly connected with four ground contact blocks 89, which are located on one side of the roller 86. After the roller 86 is raised, the ground contact block 89 contacts the ground, and the ground contact block 89 can quickly contact the ground and better support the box body 1.
[0031] Working principle: When the body 6 needs to be replaced and maintained, first remove the bolts between the connecting flange 5 and the body 6, then pull the U-shaped plate 78 to the side away from the cylinder 75, and the U-shaped plate 78 disengages from the support plate 76, driving the long rod 77 to move. The long rod 77 is separated from the inner wall of the cylinder 75 through the support plate 76 with the help of the U-shaped plate 78, and then move the body 6 to the side away from the box body 1. After the body 6 is separated from the connecting flange 5, the L-shaped plate 74 drives the cylinder 75 to move through the body 6, and the cylinder 75 is separated from the U-shaped rod 72 and then from the bottom plate 73. At this time, the body 6 is replaced and maintained. After completion, move the body 6 to the side close to the box body 1, insert the motor shaft of the body 6 into the connecting flange 5, and the L-shaped plate 74 drives the cylinder 75 to slide from the short arm of the bottom plate 73 through the body 6, and then slides from the long arm of the bottom plate 73 until the body 6 is fitted with the connecting flange 5 and then the body is released. 6. At this time, due to the inclination of the body 6 due to its own gravity, the L-shaped plate 74 drives the cylinder 75 to fit with the U-shaped rod 72, so that the body 6 can maintain a horizontal position with the connecting flange 5. Subsequently, the U-shaped plate 78 is moved to the side close to the cylinder 75, and the long rod 77 is inserted into the inner wall of the cylinder 75 through the support plate 76 with the help of the U-shaped plate 78. The long rod 77 plays a role in temporarily fixing the cylinder 75 to prevent the body 6 from moving horizontally as much as possible, thereby limiting the cylinder 75. The U-shaped plate 78 is attracted to the support plate 76, and the U-shaped plate 78 has the effect of limiting the long rod 77 to prevent it from separating from the cylinder 75. Finally, the bolts between the connecting flange 5 and the body 6 are connected. After the body 6 and the box body 1 are opened by the control panel 3, the body 6 converts DC power into mechanical energy to drive the motor shaft to rotate, and the motor shaft drives the gears in the box body 1 to rotate. The rotation of multiple sets of gears in the box body 1 causes the speed of the connecting shaft 4 to change.
[0032] When it is necessary to move the box 1 a short distance, first, the extension rod 87 is rotated with the help of the grip ball 88. The grip ball 88 facilitates the rotation of the screw 83. The top ball 84 drives the screw 83 to rotate through the extension rod 87. The screw 83 rotates and moves in the extension plate 82. The rotating plate 85 drives the roller 86 to descend through the screw 83. After the continuous rotation of the screw 83, the extension plate 82 drives the ground contact block 89 to separate from the ground with the help of the fixed plate 81. The ground contact block 89 can quickly contact the ground and better support the box 1. In this way, when moving the box 1, the fixed plate 81 drives the screw 83 to move through the box 1 with the help of the extension plate 82, and the screw 83 slides on the ground through the roller 86 with the help of the rotating plate 85.
