Description

Technical Field

[0001] The utility model belongs to the technical field of the hoisting structure of a charger, and particularly relates to a hoisting ring structure for a charger cabinet. Background Technique

[0002] With the development of electric vehicles, chargers have also seen an explosive growth. All over the country, the construction and installation of chargers are encouraged and supported to meet the charging needs of electric vehicles. When customers purchase a charger, its charging speed, appearance design, component layout, floor area, price, and ease of use directly affect its market share.

[0003] Hoisting, as a commonly used construction method, is often used in the construction process of chargers. Usually, hoisting rings and hoisting ring bases need to be installed in advance on the charger cabinet. When the hoisting ring base is connected to the cabinet body, the welding position is easily blocked by crossbeams or other components, making welding inconvenient and prone to poor connection welding. As a result, during hoisting, the cabinet body may deform and cause welding failure, or when the charger is in operation, rainwater or other impurities may enter the cabinet interior from the hoisting ring base, leading to faults. These problems restrict the installation quality and use safety of chargers. Summary of the Invention

[0004] The utility model provides a hoisting ring structure for a charger cabinet, which solves the problem of poor connection between the hoisting ring base and the cabinet body.

[0005] To achieve the above object, a hoisting ring structure for a charger cabinet according to the utility model includes a hoisting ring, a hoisting ring base, and a cabinet crossbeam. The hoisting ring base is a cylindrical two-step shaft. The upper part of the hoisting ring base passes through the cabinet crossbeam and the cabinet skin, and the upper end extends out of the cabinet skin and is fixedly connected to the hoisting ring. The step surface of the hoisting ring base is in contact with the lower end surface of the cabinet crossbeam. The cabinet skin is fully welded to the hoisting ring base, and the cabinet crossbeam is fully welded to the hoisting ring base.

[0006] Further, a threaded hole adapted to the hoisting ring is provided in the hoisting ring base.

[0007] Further, the cabinet crossbeam is an inverted "U" - shaped structure, and the cabinet crossbeam is provided with a through - hole for passing through the hoisting ring base.

[0008] Further, the cabinet crossbeam includes a first horizontal beam, a first vertical beam, a second horizontal beam, a second vertical beam, and a third horizontal beam that are connected end - to - end in sequence. The first horizontal beam, the second horizontal beam, and the third horizontal beam are parallel to each other. The first vertical beam and the second vertical beam are parallel to each other. The first vertical beam and the first horizontal beam are perpendicular to each other.

[0009] Further, the upper surfaces of the first horizontal beam and the third horizontal beam are in contact with the inner surface of the cabinet skin.

[0010] Furthermore, the lifting ring base includes a first cylinder and a second cylinder fixedly connected, the diameter of the first cylinder is smaller than the diameter of the second cylinder, and a stepped surface is formed at the connection between the diameter of the first cylinder and the second cylinder.

[0011] Furthermore, the lifting ring includes an annular component and a connecting component fixedly connected to the annular component, the connecting component having external threads.

[0012] Furthermore, the lifting ring includes an annular component and a first connecting component and a second connecting component that are fixedly connected from top to bottom. The first connecting component is cylindrical, and its outer diameter is the same as that of the lifting ring base. The outer diameter of the second connecting component is less than half the outer diameter of the first connecting component, and it is used to insert into the lifting ring base and be fixedly connected to the lifting ring base.

[0013] Furthermore, the cabinet skin has through holes that match the lifting ring base.

[0014] Furthermore, when the step of the lifting ring base contacts the cabinet beam, the marking base is in place.

[0015] Compared with the prior art, the present invention has at least the following beneficial technical effects:

[0016] This utility model optimizes the assembly method of the lifting ring base. The lifting ring base passes through the cabinet skin and the inverted "V"-shaped crossbeam, making the welding position easy to observe and operate. It will not be obstructed by the crossbeam or other parts, which can effectively improve the welding feasibility of the lifting ring base, facilitate welding operation, improve welding efficiency, ensure welding quality, and thus provide sufficient connection strength and excellent waterproof performance.

[0017] Furthermore, the lifting eye base is available in a series of specifications, and the internal blind hole thread of the lifting eye base can be selected in different specifications, and the corresponding outer diameter of the lifting eye base can be matched accordingly. Different specifications and models can be selected according to the layout of different charging cabinets.

[0018] Furthermore, the cabinet skin and cabinet beams are provided with through holes that match the lifting ring base to ensure that the lifting ring base can pass through smoothly.

[0019] Furthermore, the lifting ring includes an annular component and a connector fixedly connected to the annular component. The connector is provided with external threads. The design of the external threads allows the lifting ring to fit tightly with other components or equipment with threaded interfaces, ensuring the stability of the connection. The threaded connection method can provide sufficient strength to withstand weight and tension, ensuring the safety of lifting.

[0020] Furthermore, the lifting ring includes an annular component and a first connecting component and a second connecting component, which are fixedly connected from top to bottom. The first connecting component is cylindrical, and its outer diameter is the same as that of the lifting ring base. The outer diameter of the second connecting component is less than half the outer diameter of the first connecting component. It is used to insert into the lifting ring base and is fixedly connected to the lifting ring base. The first connecting component can seal the connection between the second connecting component and the lifting ring base, which can prevent rainwater from seeping into the connection and can also effectively prevent dust from entering the interior of the lifting ring structure.
