[0001] The utility model relates to the technical field of voltage-stabilized power supplies, in particular to a portable voltage-stabilized power supply. Background Art

[0002] A voltage stabilizer is a device used to automatically maintain a constant voltage. Depending on the design, the voltage stabilizer can be divided into DC voltage stabilizer and AC voltage stabilizer. Voltage stabilizers are often used in power supply systems and work in conjunction with rectifiers, electronic filters, etc.

[0003] The movable voltage-stabilized power supply in the prior art has a single structure, which is usually a simple combination of a simple pull handle and a small voltage-stabilized power supply body, and has not been optimized for heat dissipation and other structures. As a result, it can only be placed in an open position like an ordinary voltage-stabilized power supply, and must have space for heat dissipation. It cannot be placed in a narrow environment. For example, the voltage-stabilized power supply is often needed in the laboratory, and space must be made for each use. The air outlet of the voltage-stabilized power supply must not be blocked, which affects the experimental efficiency.

[0004] In summary, there is an urgent need for a portable voltage-stabilized power supply that can be placed in a small place without affecting heat dissipation. Utility Model Content

[0007] Preferably, a ventilation groove is provided beside the mounting groove, a slide groove is provided in the mounting groove, the building block fan or the block can slide in the slide groove, a PIN interface adapted to the building block fan is provided on one side of the mounting groove, and when the building block fan slides in the slide groove and blocks the opening, it is connected to the PIN interface.

[0008] Preferably, the power interface is rotatably arranged at a corner position of the housing, and the power interface can be located at the back or side of the housing by rotating the power interface.

[0009] Preferably, a lifting handle is provided on the top of the shell, and the lifting handle is slidably arranged in the lifting groove on the top of the shell through a slider, and the groove diameter and opening in the middle of the lifting groove are larger than the groove diameter and opening on both sides, so that the lifting handle 14 can be limited by the middle of the lifting groove when being lifted.

[0010] Preferably, a first magnet block is arranged on the mounting groove, and a second magnet block matched with the first magnet block is arranged on the building block fan or the stop block.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 4 As shown, a portable voltage-stabilized power supply includes internal components and a shell 1, the shell 1 is provided with a power interface 2, the front of the shell 1 is provided with an operation panel 3 connected to the internal components, and is characterized in that: the top, both sides and back of the shell 1 are provided with openings 11, the openings 11 are provided with mounting grooves 12, the mounting grooves 12 are used to install a building block fan 4 or a block 5, and the building block fan 4 and the block 5 are adapted to the size of the opening 11.

[0021] Furthermore, a ventilation groove 13 is provided on the side of the mounting groove 12, and a slide groove 121 is provided in the mounting groove 12. The building block fan 4 or the block 5 can slide in the slide groove 121. A PIN interface 122 adapted to the building block fan 4 is provided on one side of the mounting groove 12. When the building block fan 4 slides in the slide groove 121 and blocks the opening 11, it is connected to the PIN interface 122.

[0022] Specifically, according to different installation environments, the building block fan 4 is set at different positions on the housing 1, and the other positions that will be blocked can be installed with a block 5 to block the opening 11 to prevent debris from entering the interior. That is, the building block fan 4 is set in the direction without any obstruction to discharge air, and at this time, negative pressure will be formed in the housing 1, and the gas will enter from the ventilation groove 13 to form a stable air duct to heat the internal components.

[0023] Furthermore, when the top of the housing 1 is not blocked, a fan 4 is preferably provided on the top of the housing 1 to blow air upward to form a vertical air duct. Since the hot air generated by the internal components will rise first, discharging heat on the top of the housing 1 will have a better heat dissipation effect.

[0024] Furthermore, in order to adapt to various placement methods, the power interface 2 is rotatably set on one foot of the shell 1. By rotating the power interface 2, the power interface 2 can be located at the back or side of the shell 1, avoiding the situation where there is no space for the power plug to be inserted into the power interface 2.

[0025] Furthermore, a lifting handle 14 is provided on the top of the shell 1, and the lifting handle 14 is slidably arranged in the lifting groove 15 on the top of the shell 1 through a slider, and the groove 121 opening 11 in the middle of the lifting groove 15 is larger than the groove 121 openings 11 on both sides. By sliding the lifting handle 14, the lifting handle 4 can be prevented from blocking the fan set on the top of the shell 1.

[0026] Furthermore, a first magnet block 123 is provided on the mounting groove 12, and a second magnet block 41 matched with the first magnet block 123 is provided on the building block fan 4 and the stop block 5, which can further fix the installed building block fan 4 or the stop block 5 to prevent it from falling off when vibration occurs.
