Specifically, in the present embodiment, as shown in fig. 17 and 19, a separation groove 150 is provided between the second fixing plate 140 and the first fixing plate 120. In other words, there is a certain gap between the second fixing plate 140 and the first fixing plate 120, so it is advantageous to ensure a reliable mold process.

Specifically, in this embodiment, as shown in fig. 20, the connecting plate 130 is located at a side of the first fixing plate 120 away from the mounting plate 110, and in the installation and use state, the connecting plate 130 forms an included angle with the vertical plane, and the included angle between the two ranges from 0 ° to 40 °. In this arrangement, the angle between the connecting plate 130 and the vertical plane is suitable, and the angle between the connecting plate 130 and the mounting plate 110 is also suitable, so that the distance between the second fixing plate 140 and the first fixing plate 120 is not too large and the size of the hanging lug 100 along the length direction is not too large due to too large angle; too close two stress points of the chassis 200 due to too small included angle can not be caused, and the strengthening effect is weakened.

Further, the sum d of the gaps between the insert 141 and the bottom of the slot 211 and the inner surface of the bottom plate 210 is in the range of 0 to 0.5mm. The arrangement can ensure that the inserting piece 141 is smoothly inserted into the slot 211, even if a gap exists between the inserting piece 141 and the bottom plate 210 or between the inserting piece 141 and the slot bottom of the slot 211, the gap is also suitable, so that the inserting piece 141 can be ensured to be inserted into the slot 211 more smoothly, and the limit effect of the slot 211 on the hanging lug 100 is not influenced.

Specifically, in the present embodiment, as shown in fig. 17 and 19, the insert piece 141 is disposed at an end of the second fixing plate 140 away from the connection plate 130. In this arrangement, tab 141 is inserted into slot 211 along the length of tab 100 during assembly.

In other embodiments of the present utility model, the insert 141 is not limited to the above-mentioned installation position, for example, the insert 141 may be disposed on one side of the second fixing plate 140 along the width direction, and the opening direction of the slot 211 on the bottom plate 210 may be changed accordingly, and when assembling, the insert 141 may be inserted into the slot 211 along the width direction of the hanger 100.

Specifically, in the present embodiment, the reinforcing rib 160 is provided between the connection plate 130 and the second fixing plate 140. More specifically, as shown in fig. 17, reinforcing ribs 160 are provided between the first connection plate 131 and the second fixing plate 140, and between the second connection plate 132 and the second fixing plate 140. So set up, structural strength between first connecting plate 131 and second fixed plate 140, and structural strength between second connecting plate 132 and second fixed plate 140 all receive the enhancement for the structural strength of hangers 100 is stronger.

More specifically, in the present embodiment, the reinforcing ribs 160 are punched out. In this arrangement, the reinforcing rib 160, the connection plate 130 and the second fixing plate 140 are integrally formed, the connection strength is secured, and the process is simple. Of course, in other embodiments of the present utility model, the reinforcing rib 160 is not limited to the above-described form, and for example, the reinforcing rib 160 may be welded between the connection plate 130 and the second fixing plate 140.

Specifically, in the present embodiment, as shown in fig. 17, the hanging lugs 100 are integrally formed and are sheet metal parts formed by bending. In this arrangement, the bending process provides a guarantee for the strength of the connection between adjacent features. However, in other embodiments of the present utility model, the fixing connection manner such as welding may be used between the mounting plate 110 and the first fixing plate 120, between the mounting plate 110 and the connecting plate 130, and between the connecting plate 130 and the second fixing plate 140, so that the function of the hanger 100 may be achieved, and the strength of the flange 220 may be enhanced.

Specifically, in this embodiment, as shown in fig. 17, the first fixing plate 120 is provided with a threaded hole, the threaded hole corresponds to the through hole on the flange 220, and the fixing member passes through the through hole and is in threaded connection with the threaded hole. In this arrangement, during assembly, the fixing member passes through the through hole of the flange 220 and is then fixed to the threaded hole of the first fixing plate 120, and the thickness of the hanging tab 100 is relatively large, so that the fixing member is not easy to slide.

Specifically, in the present embodiment, the fixing member is a screw 300.

Specifically, in the present embodiment, since the connection positions of the suspension loops 100 and the chassis 200 include two positions, the number of the threaded holes on the first fixing plate 120 may be one, and the suspension loops 100 will not rotate about the axis of the screw 300 when being stressed.
