The position of the water tank 201 is referenced Fig.10 The fixing rod 103 is fixedly arranged at the bottom of the boom 102, and the fixing rod 103 has a certain angle with the horizontal and is tilted. One end of the fixing rod 103 passes through the boom 102 for rotatably installing the two connecting blocks 104. Each connecting block 104 is fixedly provided with a limiting rod 105, so that the limiting rod 105 can rotate around the fixing rod 103, and each limiting rod 105 passes through the corresponding connecting block 104. The adjusting mechanism 106 is used to drive the two limiting rods 105 to rotate, and the rotation directions of the two limiting rods 105 are opposite. In normal use, the fixing rod 103 and the two limiting rods 105 are all passed through the center hole of the wheel hub, and the wheel hub is hung on the fixing rod 103. At this time, the fixing rod 103 and the two limiting rods 105 are fixedly arranged on the bottom of the boom 102. The rod 103 supports the wheel hub alone, and then the adjusting mechanism 106 is used to drive the two limit rods 105 to rotate in opposite directions until the two limit rods 105 are respectively rotated to abut against the inner wall of the center hole of the wheel hub.

The fixing rod 103 and the two limit rods 105 form a triangle to support the wheel hub in the center hole of the wheel hub, and a total of three points support the wheel hub. The two limit rods 105 are limited on the left and right sides, so that the wheel hub cannot swing left and right around the fixing rod 103, and because the fixing rod 103 and the two limit rods 105 are all inclined, the wheel hub will not slide out, thereby solving the problem that the existing hanging hanger easily causes the wheel hub to shake during use.

[0047] Furthermore, the lifting member 107 is fixedly arranged on the top of the fixing rod 103; the lifting block 108 is arranged on the lifting member 107, and the lifting member 107 is used to drive the lifting block 108 to rise and fall; the two connecting rods 109 are respectively rotatably connected to the lifting block 108, and are respectively rotatably connected to the two limiting rods 105, and are respectively located on one side of the lifting block 108.

[0048] In this embodiment, the lifting member 107 is used to drive the lifting block 108 to move up and down, and the lifting block 108 drives the two limit rods 105 to rotate in opposite directions. Figure 8 For example, when the lifting block 108 moves upward, driven by the two connecting rods 109, the limiting rod 105 on the left rotates clockwise around the fixing rod 103, and the limiting rod 105 on the right rotates counterclockwise around the fixing rod 103.

[0049] Furthermore, the mounting frame 110 is fixedly connected to the fixing rod 103, and is slidably connected to the lifting block 108, and passes through the lifting block 108; the first screw 111 is rotationally connected to the mounting frame 110, and is threadedly connected to the lifting block 108, and passes through the lifting block 108; the first knob 112 is fixedly set on the top of the first screw 111.

[0050] In this embodiment, the mounting frame 110 is used to rotatably install the first screw rod 111 and slideably install the lifting block 108. The first knob 112 is used to facilitate the rotation of the first screw rod 111 for adjustment. The rotation of the first screw rod 111 can drive the lifting block 108 to slide and rise.

[0051] Furthermore, the lower mounting block 113 is fixedly connected to the fixed rod 103, and is rotatably connected to the first screw rod 111, and is penetrated by the fixed rod 103; the two vertical rods 114 are respectively fixedly connected to the lower mounting block 113, and are respectively slidably connected to the lifting block 108, and respectively pass through the lifting block 108; the upper mounting block 115 is respectively fixedly connected to the two vertical rods 114, and is rotatably connected to the first screw rod 111, and is located at the top of the two vertical rods 114.

[0053] Furthermore, the reinforcing rod 116 is fixedly connected to the boom 102 and to the fixing rod 103 , and is located on one side of the boom 102 .

[0054] In this embodiment, one end of the fixing rod 103 is fixedly connected to the bottom of the boom 102. The fixing rod 103 is a cantilever, so the reinforcing rod 116 is provided to support the fixing rod 103 from above to enhance the structural strength.

[0055] Furthermore, the bracket 117 is fixedly arranged at the bottom of the boom 102; the telescopic mechanism 118 is arranged at the bottom of the bracket 117; the limit block 119 is fixedly arranged at one side of the telescopic mechanism 118; and the telescopic mechanism 118 is used to drive the limit block 119 to move.

[0056] In this embodiment, the bracket 117 is a square frame, which is fixedly arranged at the bottom of the boom 102. The telescopic mechanism 118 is used to drive the limit block 119 to move. The moving direction of the limit block 119 is consistent with the length direction of the fixing rod 103 and the two limit rods 105. After the wheel hub is hung on the fixing rod 103, the wheel hub will slide along the inclined fixing rod 103. At this time, the telescopic mechanism 118 needs to be adjusted to drive the limit block 119 to block the inner wheel rim of the wheel hub from the side. And the telescopic mechanism 118 needs to be used to adjust the limit block 119 to a suitable position so that when the wheel hub is hung on the fixing rod 103, the fixing rod 103 will not extend from the center hole of the wheel hub. The position of the limit block 119 can be adjusted, so it can limit and support wheel hubs of different widths.

[0057] Furthermore, the two cross bars 120 are respectively slidably connected to the bracket 117, and are respectively fixedly connected to the limit block 119, and respectively pass through the bracket 117; the second screw 121 is threadedly connected to the bracket 117, and is rotationally connected to the limit block 119, and passes through the bracket 117; the second knob 122 is fixedly arranged on the side of the second screw 121 away from the limit block 119.

[0058] In this embodiment, the two cross bars 120 are slidably installed on the bracket 117, and the length direction is consistent with the length direction of the fixed rod 103, so that the limit block 119 can be moved. By rotating the second screw rod 121, the position of the limit block 119 can be moved and adjusted, and the second knob 122 is used to facilitate the rotation and adjustment of the second screw rod 121.

[0059] Furthermore, the limit block body 123 is fixedly connected to the two cross bars 120 respectively, and is rotatably connected to the second screw 121, and is located on the side of the second screw 121 away from the second knob 122; the slider 124 is slidably arranged inside the limit block body 123; the two support rods 125 are fixedly connected to the slider 124 respectively, and pass through the limit block body 123 respectively; the third screw 126 is rotatably connected to the limit block body 123, and is threadably connected to the slider 124, and passes through the slider 124; the third knob 127 is fixedly arranged at the bottom of the third screw 126.

[0060] In this embodiment, the limit block body 123 has a cavity inside for slidingly installing the slider 124. By rotating the third screw rod 126, the slider 124 can be driven to slide and rise and fall. When in use, after the side of the limit block body 123 away from the second screw rod 121 blocks the inner rim of the wheel hub from the side, the third knob 127 can be rotated to drive the slider 124 to slide, so that the slider 124 drives the two support rods 125 to move upward and support the inner rim of the wheel hub from below; using the above method, the wheel hub is jointly limited and supported by the fixing rod 103, the two limit rods 105, the limit block body 123 and the two support rods 125.

[0061] Furthermore, the first sleeve 129 is sleeved on the fixing rod 103 ; and the two second sleeves 130 are sleeved on the two limiting rods 105 respectively.

[0062] In this embodiment, the first sleeve 129 and the second sleeve 130 respectively protect the fixing rod 103 and the limiting rod 105 from corrosion and slip.

[0063] The present embodiment describes a hanging type hanger suitable for multi-size wheel hubs. When in use, the fixing rod 103 and the two limiting rods 105 are passed through the center hole of the wheel hub, and the wheel hub is hung on the fixing rod 103. At this time, the fixing rod 103 alone supports the wheel hub. Then, the first knob 112 is rotated to make the two limiting rods 105 rotate in opposite directions until the two limiting rods 105 are respectively rotated to abut against the inner wall of the center hole of the wheel hub. Then, the wheel hub is slid to adjust the position of the wheel hub on the fixing rod 103, and the second knob 122 is rotated to adjust the wheel hub. The position of the limit block body 123 allows the limit block body 123 to block the inner rim of the hub from the side, so that the hub will not slide down excessively along the inclined fixing rod 103, causing the fixing rod 103 and the two limit rods 105 to extend from the center hole of the hub, and finally the third knob 127 is rotated to drive the two support rods 125 to move up and support the inner rim of the hub; it should be noted that after adjusting the positions of the two limit rods 105, the limit block body 123 and the two support rods 125, when the hub of the same size is mounted subsequently, no adjustment is required and it can be directly mounted.
