[0028] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0029] Example:

[0030] As attached Figure 1 To Attachment Figure 6 As shown:

[0031] The utility model provides a mobile test low-voltage power supply, comprising a placement box 11 and a low-voltage power supply body 12. The placement box 11 adopts a box-shaped appearance, and a placement groove 13 is opened on one side. A mounting box 14 is installed at the bottom of the placement groove 13 for fixing the low-voltage power supply body 12. A mounting groove 15 is opened on the inner side of the mounting box 14, and the low-voltage power supply body 12 can be disassembled and assembled through the mounting groove 15, which solves the problem that the traditional fixed power supply is large in size and occupies a large area; the low-voltage power supply body 12 can be firmly fixed in the mounting groove 15 through a built-in fixing component, so that the low-voltage power supply body 12 remains stable during the mobile test; in addition, a through groove is also opened on one side of the placement box 11, and a side plate 16 is arranged in the through groove, and a detection component electrically connected to the low-voltage power supply body 12 is arranged on the side plate 16, so that the integration of the detection function is realized. Finally, a moving component is arranged at the bottom of the placement box 11, so that the power supply is convenient to move.

[0032] Please refer to Figure 2 , Figure 3 and Figure 4 As shown, the fixing assembly includes two groups of fixing seats 21, and the two groups of fixing seats 21 are fixedly connected to one side of the installation box 14 by multiple groups of screws. The two groups of fixing seats 21 adopt a symmetrically arranged structure to ensure the position stability of the low-voltage power supply body 12 in the installation box 14; and each group of fixing seats 21 is provided with a slidable locking rod 22.

[0033] Please refer to Figure 3 and Figure 4As shown, the fixing assembly also includes a connecting plate 23, which is arranged on one side outer wall of the low-voltage power supply body 12. In order to achieve a stable connection between the low-voltage power supply body 12 and the installation box 14, two groups of corresponding locking grooves 24 are opened on the inner side of the connecting plate 23; the positions of the two groups of locking grooves 24 correspond to the positions of the two groups of locking rods 22 in the installation box 14. When the low-voltage power supply body 12 is installed in the installation box 14, the two groups of locking rods 22 will respectively extend into the two groups of locking grooves 24 in the connecting plate 23. By the locking rods 22 passing through the locking grooves 24 opened in the connecting plate 23, a stable connection between the low-voltage power supply body 12 and the installation box 14 is achieved, so that the low-voltage power supply body 12 is effectively fixed in all directions during the mobile test to prevent structural damage caused by road bumps and other reasons.

[0034] Please refer to Figure 4 As shown, in order to realize the easy operation of the locking rod 22, the two sets of locking rods 22 are provided with a handle 25 at one end away from the connecting plate 23, and the handle 25 is connected to the fixing seat 21 fixed on the inner wall of the installation box 14 through a spring 26. In the normal installation state, the spring 26 causes the handle 25 to retract inward, and at the same time drives the locking rod 22 to extend into the locking groove 24 in the connecting plate 23, so as to complete the locking of the low-voltage power supply body 12 and the installation box 14. When the low-voltage power supply body 12 needs to be disassembled or replaced, it is only necessary to pull the handles 25 of the two sets of locking rods 22 outward at the same time. By pulling the handle 25, the spring 26 can be compressed to drive the corresponding locking rod 22 to withdraw from the locking groove 24 of the connecting plate 23.

[0035] In order to realize the rapid forward and backward movement of the low-voltage power supply body 12 in the installation box 14, the inner walls on both sides of the installation groove 15 are provided with parallel extending slide rails 27, and the outer walls on both sides of the low-voltage power supply body 12 are provided with corresponding sliders 28. The sliders 28 can slide forward and backward along the guide rail direction of the slide rails 27 through multiple groups of sliding wheels 29 installed thereon; the structure of the slide rails 27, the sliders 28 and the sliding wheels 29 not only ensures the stable guidance of the low-voltage power supply body 12 in the installation box 14, but also greatly reduces the resistance during its movement.

[0036] Please refer to Figure 2 As shown, the mobile assembly includes multiple sets of running wheels 31, and the bottom of the placement box 11 is connected to the multiple sets of running wheels 31 through multiple sets of shock absorbers 32. The shock absorbers 32 can reduce the impact of the running wheels 31 on the bottom surface of the placement box 11, thereby protecting the electronic equipment from vibration. In addition, a pull rod 33 is also provided on one side of the placement box 11. The tester can pull or push the pull rod 33 to move the placement box 11 as a whole together with the built-in low-voltage power supply body 12, so that the mobile power supply can be easily and quickly carried to different test sites or locations by the tester, and the vibration impact on the electronic equipment is also effectively reduced during the walking process.

[0037] Please refer to Figure 2 , Figure 5 and Figure 6 As shown, the detection component includes two groups of detectors 41, and a mounting groove 42 is provided on the side plate 16 of the mounting groove 15 away from the low-voltage power supply body 12, and two groups of detectors 41 are evenly spaced in the mounting groove 42; the two groups of detectors 41 are electrically connected to the low-voltage power supply body 12 through wires, and they can monitor the output parameters of the low-voltage power supply body 12 in real time. The use of two groups of detectors 41 to achieve multi-point synchronous monitoring can effectively improve the quality and efficiency of long-term continuous testing.

[0038] Please refer to Figure 5 and Figure 6 As shown, the detection component also includes two sets of power plugs 43. The shells of the two sets of detectors 41 are provided with power plugs 43. The power plugs 43 adopt a standard plug structure and can safely connect the detectors 41 to the low-voltage power supply body 12. The power plugs 43 can effectively prevent the occurrence of electric shock accidents, and the power plugs 43 make the wiring safer and more reliable.

[0039] Please refer to Figure 1 and Figure 2 As shown, in order to better install and maintain the detector 41, the detection component is further provided with a first door panel 44 at the opening of the assembly groove 42. The first door panel 44 is rotatably connected to the two sides of the side panel 16 through two sets of hinges, so that the first door panel 44 can be pulled open like a door to facilitate the removal or installation of the detector 41 from the opening. At the same time, a first handle 45 is further provided on the outer side of the first door panel 44. By pulling or pushing the first handle 45, the first door panel 44 can be easily opened or closed to achieve access to the detector 41.

[0040] Please refer to Figure 2 As shown, a plurality of groups of first heat dissipation grooves 17 are evenly arranged on the surrounding side of the installation box 14, and these first heat dissipation grooves 17 are beneficial to the rapid conduction and convection of heat from the surface of the box to the environment by increasing the surface area; a second heat dissipation groove 18 is arranged on the inner side of the side panel 16 corresponding to the side opposite to the placement box 11; a rotatable second door panel 19 is arranged on the placement groove 13, and the second door panel 19 is connected to the placement box 11 by two groups of hinges, and can be opened like the first door panel 44, so as to facilitate the maintenance of the internal equipment; a second handle 20 is also arranged on the outer side of the second door panel 19, and the second door panel 19 can be conveniently opened by the second handle 20.
