Pair of buckling 360-degree limiting efficient air supply outlet lugs

Abstract

This utility model provides a pair of interlocking, 360-degree limiting high-efficiency air outlet lifting lugs. They only need to be welded to the four corners of the high-efficiency air outlet unit housing. The interlocking of the top surface and the positioning folded edge achieves 360-degree limiting when the upper and lower parts are interlocked, without the need for any fasteners, saving packaging materials. At the same time, this utility model provides convenience for the hoisting of the unit, which can be hoisted from the top or installed from the side using hooks. It can also be used as a vehicle loading and lifting device.

Description

Technical Field

[0001] This utility model relates to a high-efficiency air outlet hanger in the field of heating, ventilation and air conditioning, and in particular to a pair of interlocking, 360-degree limiting high-efficiency air outlet hanger lugs. Background Technology

[0002] High-efficiency air outlets often use bolt-connected lifting rings or equilateral L-shaped bent plates and four-corner welded lifting lugs to integrate with the high-efficiency air outlet housing. When packaging in groups, the mating surfaces of the high-efficiency air outlets placed on opposite sides need to be padded with soft materials to prevent rubbing or additional bolt connections to prevent the unit from shaking. When disassembling or assembling a single unit, the lifting rings or lugs are easily deformed by external forces. Summary of the Invention

[0003] To further address the shortcomings of existing lifting devices for high-efficiency air outlets, this invention provides a pair of interlocking, 360-degree limiting lifting lugs for high-efficiency air outlets. These lugs only need to be welded to the four corners of the high-efficiency air outlet unit housing. The interlocking of the top surface and the positioning folded edges achieves 360-degree limiting when the units are interlocked, eliminating the need for any fasteners and saving on packaging materials. Furthermore, this invention facilitates the lifting of the unit, allowing it to be lifted from above or installed from the side using hooks. It can also be used as a loading and lifting device for vehicles.

[0004] The technical solution adopted by this utility model to solve its technical problem is as follows: It provides a pair of interlocking, 360-degree limiting high-efficiency air outlet lifting lugs, made of 2mm thick sheet metal, with processing involving only two steps: laser blanking and bending, or mold forming. The structural features of this utility model are: the main sheet metal structure is an equilateral right-angled L-shape, with an added top surface and three staggered positioning folds with different bending directions. The interlocking of the top surface and the positioning folds achieves 360-degree limiting when the high-efficiency air outlet is interlocked.

[0005] The sheet metal body of this utility model is an equilateral right-angled L-shape, with the width B and height H of both sides being the same. One side has an annular groove in the height direction to facilitate hook installation. A top surface is added, with a semi-keyway through-hole at the center along the bending direction. Two positioning folds are provided on both sides of the semi-keyway through-hole. Positioning fold 1 on the side that is in contact with the side is bent upwards, with a bending dimension greater than the side width by 1.5mm (i.e., dimension a). Positioning fold 2 on the non-side contact side is bent downwards, with a bending dimension less than the side width by 3.5mm. The dimensions are as follows: Dimension b; A positioning fold 3 is left on the non-side-fitting side away from the side edge. The positioning fold 3 is bent upwards and the bending size is 1.5mm larger than the side width, i.e., dimension c. The dimension at the non-positioning fold 3 is 2mm shorter than the side width, i.e., dimension d. To ensure the overall appearance of this utility model and the stability of the placement of a single high-efficiency air outlet, the bending height of the three positioning folds is kept consistent under the condition that the processing conditions allow, and the minimum forming size is taken; The minimum value of the positioning fold width is limited to 7.5mm.

[0006] The beneficial effects of this utility model are: it provides a pair of interlocking, 360-degree limiting high-efficiency air outlet lifting lugs, which only need to be welded to the four corners of the high-efficiency air outlet unit box. The interlocking of the top surface and the positioning folded edge achieves 360-degree limiting when the upper and lower parts are interlocked, without the need for any fasteners, saving packaging materials; at the same time, this utility model provides convenience for the hoisting of the unit, which can be hoisted from the top or installed from the side using a hook, and can also be used as a loading and lifting device.

[0012] like Figure 1 As shown, this utility model uses a 2mm thick sheet metal, and the processing and forming only involves two processes: laser blanking and bending, or mold forming; the main sheet metal structure is an equilateral right-angled L-shape, with an added top surface and three staggered positioning folds with different bending directions added to the top surface. The 360-degree limit of the high-efficiency air outlet when it is locked together is achieved by using the mutual locking of the top surface and the positioning folds.

[0013] The sheet metal body of this utility model is an equilateral right-angled L-shape, with the width B and height H of both sides being the same. One side has an annular groove in the height direction to facilitate hook installation. A top surface is added, with a semi-keyway through-hole at the center along the bending direction. Two positioning folds are provided on both sides of the semi-keyway through-hole. Positioning fold 1 on the side that is in contact with the side is bent upwards, with a bending dimension greater than the side width by 1.5mm (i.e., dimension a). Positioning fold 2 on the non-side contact side is bent downwards, with a bending dimension less than the side width by 3.5mm. The dimensions are as follows: Dimension b; A positioning fold 3 is left on the non-side-fitting side away from the side edge. The positioning fold 3 is bent upwards and the bending size is 1.5mm larger than the side width, i.e., dimension c. The dimension at the non-positioning fold 3 is 2mm shorter than the side width, i.e., dimension d. To ensure the overall appearance of this utility model and the stability of the placement of a single high-efficiency air outlet, the bending height of the three positioning folds is kept consistent under the condition that the processing conditions allow, and the minimum forming size is taken; The minimum value of the positioning fold width is limited to 7.5mm.
