[0032] A DC current source is a power supply device that can provide a stable DC current. Its circuit principle includes a current controller, a current sensor, a current stabilizer, and a protection circuit. DC current sources are used in applications that require constant current, such as electrochemical experiments, resistor load testing, and LED driving. They have important application value in fields such as laboratories, industrial production, and electronic equipment testing.

[0033] With the rapid development of new energy equipment, communication base stations and outdoor testing devices, DC current sources, as core power supply equipment, are increasingly widely used in outdoor scenarios. However, existing DC current sources have poor terrain adaptability in complex outdoor environments, resulting in unstable connection with ammeters and affecting their use.

[0034] This invention proposes a DC current source with a support structure, aiming to provide support for the main body of the current source when used outdoors, thereby improving its adaptability to different terrains.

[0035] Please see Figures 1 to 3 In one embodiment of this utility model, the DC current source 100 with a support structure includes a current source body 1, a support component 2, and a fixing component 3. The support component 2 is disposed at the bottom of the current source body 1. The support component 2 includes an adjusting rod 21 and two support parts 22. The lower ends of the two support parts 22 are rotatably mounted to the ground, and the upper ends of the two support parts 22 are slidably disposed on the adjusting rod 21. The distance between the two support parts 22 is adjustable so that the height of the current source body 1 relative to the ground is adjustable. The fixing component 3 includes two fixing parts 31, which are disposed one-to-one with the two support parts 22 to fix the support parts 22 to the adjusting rod 21.

[0036] The technical solution of this utility model, by employing the adjustable setting of the support component 2, allows the current source body 1 to be adjusted to a suitable height according to actual needs, enhancing the flexibility and practicality of the current source body 1 during use. The rotatable installation of the support part 22 with respect to the ground helps maintain the stability of the current source body 1 under different terrain conditions. Simultaneously, the setting of the fixing component 3 improves the stability of the support part 22 on the adjusting rod 21, reducing the swaying or tilting of the current source body 1 caused by external forces, further enhancing the safety of the current source body 1 in use.

[0037] Furthermore, in some embodiments, the support portion 22 can be configured in various ways. For example, the support portion 22 can be a rod-shaped structure, a plate-shaped structure, or a structure of other shapes. In this embodiment, preferably, the support portion 22 is a rod-shaped structure.

[0038] Specifically, in one embodiment, the support part 22 includes a support rod 221, the upper end of which is rotatably connected to the outer peripheral wall of the adjusting rod 21. Thus, the rotatable connection between the support rod 221 and the adjusting rod 21 further improves the adaptability and stability of the current source body 1 under different terrain conditions. When it is necessary to adjust the height of the current source body 1, the user only needs to loosen the fixing component 3, slide the support part 22 on the adjusting rod 21, and then fix the support part 22 again using the fixing component 3 to achieve the height adjustment of the current source body 1. This simple operation greatly improves the flexibility and practicality of the current source body 1 during use.

[0039] Furthermore, the DC current source 100 with a support structure also includes two mounting portions 4; each mounting portion 4 includes a mounting sleeve 41, which is sleeved on the outer peripheral wall of the adjusting rod 21, and the outer peripheral wall of the mounting sleeve 41 is rotatably connected to the upper end of the support rod 221. Thus, the mounting sleeve 41 provides more installation space for the support rod 221, thereby facilitating the installation of the upper end of the support rod 221 and improving the flexibility of the support rod 221.

[0040] It should be noted that the inner wall of the mounting sleeve 41 is slidably connected to the outer peripheral wall of the adjusting rod 21, which facilitates the movement of the support rod 221.

[0041] In some embodiments, the fixing method between the adjusting rod 21 and the support part 22 can be varied, such as bolt connection or snap-fit ​​connection.

[0042] Specifically, to improve the smoothness of adjustment of the support 22, in one embodiment, the outer peripheral wall of the adjusting rod 21 is threaded, and the fixing part 31 is threadedly connected to the adjusting rod 21. Thus, the threaded connection between the fixing part 31 and the adjusting rod 21 improves the stability of the support 22 on the adjusting rod 21. Simultaneously, the threaded connection allows the user to adjust the position of the support 22 on the adjusting rod 21 by rotating the fixing part 31 according to actual needs, thereby achieving precise adjustment of the height of the current source body 1.

[0043] It is worth mentioning that in this embodiment, there is no specific restriction on the thread pattern engraved on the adjusting rod 21. It can be engraved in the same direction or symmetrically.

[0044] like Figure 4 As shown, specifically in this embodiment, the outer peripheral wall of the adjusting rod 21 is threaded, and the thread directions of the adjusting rod 21 are symmetrically arranged. This arrangement not only enhances the structural strength of the adjusting rod 21 but also ensures that the fixing part 31 is evenly stressed during rotation, reducing rotational jamming or loosening problems that may occur due to a single thread direction. Furthermore, the symmetrical thread design provides users with a smoother and more stable operating experience when adjusting the position of the support part 22, improving reliability.

[0045] To fix the support 22 in a sliding position on the adjusting rod 21, the fixing part 31 can adopt various structural forms. In this embodiment, preferably, the fixing part 31 includes two threaded sleeves 311, which are sleeved on the outer peripheral wall of the adjusting rod 21 and threadedly connected thereto. Thus, by clamping the support 22 between the two threaded sleeves 311 on the outer peripheral wall of the adjusting rod 21, the support 22 is clamped and fixed by rotating the two threaded sleeves 311.

[0046] Of course, the fixing part 31 can also be in other structural forms, such as buckles, clamps, etc., as long as it can fix the position of the support part 22 on the adjusting rod 21.

[0047] To facilitate the movement of the support portion 22, in one embodiment, the DC current source 100 with the support structure further includes two mounting portions 4, each including a mounting sleeve 41, which is fitted onto the outer peripheral wall of the adjusting rod 21.

[0048] In some embodiments, the adjusting rod 21 can be positioned in various ways. It can be positioned outside the current source body 1 for convenient operation, or it can be positioned inside the current source body 1 to improve the safety of the adjusting rod 21.

[0049] Specifically, in one embodiment, a receiving cavity 11 is provided at the bottom of the current source body 1, and both ends of the adjusting rod 21 are connected to the inner wall of the receiving cavity 11. Thus, by connecting both ends of the adjusting rod 21 to the inner wall of the receiving cavity 11, the support assembly 2 can be stably mounted on the bottom of the current source body 1, improving the connection strength between the support assembly 2 and the current source body 1, and further enhancing the stability of the current source body 1 during use. Simultaneously, the receiving cavity 11 also protects the adjusting rod 21, preventing damage from the external environment during use and extending the service life of the DC current source 100 with the support structure.

[0050] Furthermore, to further improve the stability of the current source body 1 under different terrain conditions, in one embodiment, the DC current source 100 with a support structure also includes a support pad 5. The support pad 5 is disposed at the lower end of the two support parts 22 and is hinged to the two support parts 22. This arrangement, with the support pad 5 located at the lower end of the support parts 22, increases the friction between the support parts 22 and the ground, thereby improving the stability of the current source body 1. Simultaneously, the hinged installation method allows for more flexible movement of the support pad 5 and better adaptability.

[0051] Furthermore, in one embodiment, the bottom of the support pad 5 is provided with anti-slip particles. This increases the friction between the support portion 22 and the ground, resulting in better support.

[0052] Furthermore, in one embodiment, four sets of support components 2 are provided, each located at one of the four corners of the bottom of the current source body 1. This arrangement of four sets of support components 2 effectively distributes the weight of the current source body, reducing pressure on any single support point and thus extending the service life of the support structure. Moreover, it maintains a level position, particularly when the current source body is used on uneven surfaces, thereby improving the accuracy and reliability of the equipment operation.

[0053] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
