DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings.

[0018] It should be noted that if there are directional indication terms in the present invention, such as up, down, left, right, front, and back directions and orientation terms, they are for the purpose of facilitating the description of the relative position relationship between components, and are not for the absolute position of the related components or the position relationship between components. They are only used to explain the relative position relationship and movement of the components in a certain posture. If the specific posture changes, the directional indication will also change accordingly. If there are terms related to quantity in the present invention, such as "multiple", "multiple", "several", etc., they specifically refer to two or more.

[0019] like Figure 1-3As shown, the duct machine lifting ear installation structure, the lifting ear 1 includes a lifting part 11 and a connecting part 12, the connecting part 12 is provided with a first opening 13, the upper side of the first opening 13 is provided with a first hook 14 folded upward, the side plate 2 of the duct machine for installing the lifting ear 1 is provided with a second opening 21, the lower side of the second opening 21 is provided with a second hook 22 folded downward, the lower edge of the first opening 13 is clamped in the second hook 22 and contacts the bottom of the second hook 22, the upper edge of the second opening 21 is clamped in the first hook 14 and contacts the bottom of the first hook 14. As shown in the figure, the first opening 13 and the second opening 21 have the same structural size, and the first hook 14 and the second hook 22 have the same structure, but they are in different directions. During installation, first let the second hook 22 pass through the first opening 13, and at the same time, let the first hook 14 pass through the second opening 21, and then move the ear 1 upwards so that the first hook 14 is engaged with the upper edge of the second opening 21, and at the same time, the second hook 22 is engaged with the lower edge of the first opening 13, so that the ear 1 is connected to the duct machine through the first hook 14 and the second hook 22. To ensure a stable connection, the opening size of the first hook 14 and the second hook 22 can be designed to be equal to or slightly smaller than the thickness of the side panel 2 and the connecting part 12, so that the hook can be stably connected to the edge of the opening through the friction of the tight connection.

[0020] Furthermore, in order to improve the stability of the connection between the lifting ear 1 and the side plate 2, a through hole 15 is provided on the lifting ear 1, and a screw hole 23 is provided on the side plate 2 at a position corresponding to the through hole 15, and the lifting ear 1 is fixed to the side plate 2 by a screw 3 passing through the through hole 15. The above corresponding position means that when the lifting ear 1 is clamped and fixed to the side plate 2, the through hole 15 is aligned with the screw hole 23. The screw 3 only serves to assist in fixing the lifting ear 1 and does not provide bearing capacity for the side plate 2, so only one screw 3 is required.

[0021] Because the thickness of the lifting ear 1 and the side plate 2 are both relatively thin, in order to improve the connection strength, two first openings 13 can be set on the lifting ear 1, and two second openings 21 are correspondingly set on the side plate 2, and the through hole 15 is set in the middle area of ​​the two first openings 13. By setting two openings at intervals, the bearing area of ​​the lifting ear 1 to the side plate 2 can be increased, thereby improving the connection strength. Compared with setting a whole long opening, setting two openings at intervals will not cause the lifting ear 1 or the side plate 2 to deform due to the larger opening size, ensuring structural stability.

[0022] As for the specific structure of the lifting ear 1, the solution adopted by the utility model is that the lifting part 11 and the connecting part 12 of the lifting ear 1 are two plate-like structures at 90 degrees to each other. In order to improve the rigidity of the lifting ear 1, a flange structure 16 is provided on the edge of the plate-like structure. At the same time, the flange structure 16 can also play a role in preventing hands from being scratched, thereby improving the safety of installation. In addition, in order to prevent the lifting ear 1 from deforming, a triangular rib 17 is provided at the connection between the lifting part 11 and the connecting part 12. The processing method of the triangular rib 17 is as follows: Figure 1 , Figure 2 As shown, a wedge-shaped punch head is used to punch inwardly from the outside of the connection part between the hanging part 11 and the connection part 12, so that the connection part is concave inward to form two triangular surfaces, thereby improving the bending resistance of the connection part. The triangular ribs 17 preferably also include two, corresponding to the two first openings 13 respectively.

[0023] In order to facilitate the connection between the lifting ear 1 and the lifting screw, a lifting hole 4 for connecting the lifting screw is provided on the lifting portion 11. The specific structure of the lifting hole 4 is as follows: Figure 2 As shown, the hoisting hole 4 includes an entrance section 41 and a connecting section 42. The connecting section 42 is a strip-shaped hole whose length direction is parallel to the intersection line of the hoisting part 11 and the connecting part 12. The entrance section 41 is an opening extending from the side of the hoisting part 11 away from the connecting part 12 to the opening connected to the connecting section 42. The widths of the entrance section 41 and the connecting section 42 should be larger than the outer diameter of the hoisting screw. When installing, first put the hoisting screw from the entrance section 41 into the connecting section 42, then adjust the installation position, and finally clamp the hoisting part 11 on the hoisting screw with two sets of nuts and washers. The hoisting hole 4 can improve the convenience of connecting the lifting ear 1 with the hoisting screw, and is also conducive to fine-tuning the position of the lifting screw and the lifting ear.

[0024] The utility model arranges openings and hooks that are engaged with each other on the lifting ear 1 and the side plate 2 of the duct machine, and realizes the connection between the lifting ear 1 and the side plate 2 by means of a clamping method. The installation is convenient and the connection is stable and reliable. Compared with traditional welding and screw connections, this method has the advantages of simple operation, high installation precision, low production cost, etc., and has good practicality and application value.
