Description

Technical Field

[0001] This application relates to the technical field of inverter handles, and more particularly to a handle structure and housing for an inverter. Background Technology

[0002] In the handling of heavy-duty enclosures (typically weighing ≥20kg) such as industrial equipment and inverter cabinets, the reliability, comfort, and cost of the handle structure are key design factors. Currently, inverter enclosure handles mainly adopt the following two solutions:

[0003] Independent hardware handles: Directly purchase standardized metal round bar handles (such as stainless steel bars with a diameter of 10~15mm) and fix them to the side or top of the chassis with bolts.

[0004] Composite handles: Metal handles are covered with a plastic sleeve (such as TPU material) to increase the grip diameter (e.g., up to 25~30mm) and improve comfort.

[0005] However, the above solutions have obvious limitations: the diameter of the metal round bar handle is too small (usually <15mm), and when lifting the heavy machine box, the pressure is concentrated on the palm, causing pain and even safety hazards. The plastic coating is prone to brittleness and cracking under outdoor ultraviolet rays and high and low temperature environments, which cannot meet the needs of long-term outdoor use.

[0006] Therefore, there is an urgent need to solve the technical problem of a handle structure that is both anti-squeezing and weather-resistant.

[0007] The above content is only used to help understand the technical solution of this application and does not represent an admission that the above content is prior art. Utility Model Content

[0008] The main purpose of this application is to provide a handle structure for inverters, which aims to solve the problems of handles on existing inverter chassis being too tight and having poor weather resistance.

[0009] To achieve the above objectives, this application provides a handle structure for an inverter, including a sheet metal frame mounted on a chassis. The sheet metal frame has at least one through hole, and the edge of the through hole has two sheet metal flanges that bend inward or outward. A slit steel pipe is disposed between the two sheet metal flanges, and the slit steel pipe and the through hole form a finger gripping space.

[0010] As a preferred embodiment of this application, it also includes sheet metal rolled edges, wherein the sheet metal frame is provided with the sheet metal rolled edges on the opposite side of the cut steel pipe.

[0011] As a preferred embodiment of this application, the sheet metal fold is an L-shaped rolled edge structure or a U-shaped rolled edge structure.

[0012] As a preferred embodiment of this application, the diameter of the slit steel pipe is ≥25mm, and the outer surface is covered with anti-slip texture or powder coating.

[0013] As a preferred embodiment of this application, the slit steel pipe is fixed to the sheet metal frame by full welding or spot welding.

[0014] As a preferred embodiment of this application, the through hole is an oblong hole or a rectangular hole, and its length direction is parallel to the axis of the slit steel pipe.

[0015] As a preferred embodiment of this application, the thickness of the sheet metal frame is 1.5~3mm, and the wall thickness of the slit steel pipe is 1~2mm.

[0016] A chassis, suitable for the handle structure described in any of the above claims, wherein two sheet metal frames are symmetrically arranged on the chassis.

[0017] This application provides a handle structure for an inverter, which is designed with no plastic material and has an all-metal structure. It is resistant to ultraviolet rays and high and low temperatures, and has better overall weather resistance. By opening through holes in the sheet metal frame and using a combination of sheet metal folded edges and cut steel pipes, it conforms to ergonomics. The sheet metal folded edges on the top and bottom sides can prevent the edges of the through holes from directly contacting the fingers during use, thus avoiding problems such as scratching the fingers or hurting the hands.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 In one embodiment, a handle structure for an inverter includes a sheet metal frame 1 disposed on a chassis 6. The sheet metal frame 1 has at least one through hole 2. The edge of the through hole 2 is provided with two sheet metal folds 3 that bend inward or outward. A slit steel pipe 4 is disposed between the two sheet metal folds 3, and the slit steel pipe 4 and the through hole 2 form a finger gripping space.

[0026] Preferably, the through hole 2 is an oblong or rectangular hole, and its length direction is parallel to the axis of the slit steel pipe 4.

[0027] It is understandable that this application adopts a plastic-free material design and an all-metal structure, which can resist ultraviolet rays, high and low temperatures, and has better overall weather resistance. By opening through holes 2 on the sheet metal frame 1, and using the combination design of sheet metal folded edges 3 and cut steel pipes 4, it conforms to ergonomics. Through the sheet metal folded edges 3 on the upper and lower sides, it can avoid direct contact between the edge of the through hole 2 and the fingers during use, thus preventing problems such as scratching fingers or hurting hands.

[0028] Specifically, please refer to Figure 2 , Figure 3 Based on the above embodiments, it also includes sheet metal rolled edges 5, and the sheet metal frame 1 is provided with sheet metal rolled edges 5 on the opposite side of the cut steel pipe 4.

[0029] It is understandable that by setting the sheet metal rolled edge 5, the through hole 2 is surrounded by sheet metal rolled plate, cut steel pipe 4, and sheet metal folded edge 3. During use, the user will not come into direct contact with the through edge, which further provides safety protection and can effectively reduce or reduce the possibility of scratches or cuts to the user's hands after prolonged contact with the sharp edge of the through hole 2 during the process of moving the inverter.

[0030] Specifically, please refer to Figure 2 , Figure 3 Based on the above embodiments, the sheet metal fold 3 is an L-shaped rolled edge structure or a U-shaped rolled edge structure.

[0031] It is understandable that the sheet metal fold 3 is an L-shaped or U-shaped rolled edge structure, which allows for surface contact with the user's fingers during use, thus preventing the finger from being injured if the edge of the through hole 2 comes into line contact with the finger.

[0032] Specifically, based on the above embodiments, the diameter of the slit steel pipe 4 is ≥25mm, and the outer surface is covered with anti-slip texture or powder coating.

[0033] It is understandable that the diameter of the slit steel pipe 4 is ≥25mm, which is larger than the diameter of the traditional handle. By setting anti-slip texture and powder coating, beneficial friction can be increased and the occurrence of slippage can be reduced.

[0034] Specifically, based on the above embodiments, the slit steel pipe 4 is fixed to the sheet metal frame 1 by full welding or spot welding.

[0035] It is understandable that using welding connection method is more stable overall. Since welding has no threaded parts, it can completely avoid the risk of bolts loosening in a vibrating environment.

[0036] Specifically, based on the above embodiments, the thickness of the sheet metal frame 1 is 1.5~3mm, and the wall thickness of the slit steel pipe 4 is 1~2mm.

[0037] It is understandable that a sheet metal frame thickness of 1.5~3mm can ensure a balance between structural strength and processing feasibility; a steel pipe wall thickness of 1~2mm can optimize grip comfort and welding reliability.

[0038] A chassis 6, suitable for the handle structure of any of the above, wherein two sheet metal frames 1 are symmetrically arranged on the chassis 6.

[0039] It is understandable that the chassis 6 itself is designed to include a sheet metal frame 1, which is welded together by using the sheet metal frame 1 itself and the cut steel pipe 4. At the same time, a sheet metal folded edge 3 is formed by bending on the sheet metal frame 1. Compared with the independently installed stainless steel handle, the handle provided in this application has a relatively low overall cost in terms of material cost and process cost.

[0040] It should be noted that, in this document, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, apparatus, article, or method that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, apparatus, article, or method. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, apparatus, article, or method that includes that element.

[0041] The above description is only a preferred embodiment of this application and does not limit the patent scope of this application. Any equivalent structural or procedural transformations made based on the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
