Description

Technical Field

[0001] The present application relates to the technical field of switching power supplies, and in particular to a switching power supply with a stable structure. Background Art

[0002] A switching power supply, also known as an exchange power supply or a switching converter, is a high-frequency power conversion device and a type of power supply. Its function is to convert a voltage level into the voltage or current required by the user through different forms of architecture. The input of a switching power supply is mostly AC power (such as mains) or DC power, and the output is mostly a device that requires DC power, such as a personal computer, and the switching power supply performs the voltage and current conversion between the two.

[0003] In the prior art, the installation of the switching power supply is usually performed by first fixing the switching power supply to an L-shaped bracket with bolts, and then fixing the L-shaped bracket to a wall. Although the structure of installing the switching power supply in this way is simple and convenient, when repairing the switching power supply, it is necessary to unscrew the bolts and then remove the switching power supply. After multiple repairs, the threads of the bolts and the threads of the mounting screw holes opened by the switching power supply will be worn, and the installation structure of the switching power supply after wear will be unstable. Therefore, a switching power supply with a stable structure is needed to solve this technical problem. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of the present application is to provide a switching power supply with a stable structure to solve the technical problem in the prior art that the mounting structure of the switching power supply becomes unstable due to wear and tear after multiple repairs.

[0005] The above-mentioned purpose of the present application is achieved through the following technical solutions: a switching power supply with a stable structure, including a switching power supply, an L-shaped bracket and a fixing device, the fixing device including a sleeve and a sleeve column, the sleeve is fixedly connected to a vertical surface of the L-shaped bracket, the sleeve column is fixedly connected to one side of the switching power supply, and a mounting screw hole for mounting on a wall is provided at one horizontal end of the L-shaped bracket, and the sleeve column is inserted into the sleeve.

[0006] By adopting the above technical solution, the L-shaped bracket is installed on the wall through the installation screw holes, and then the sleeve column fixedly connected to the switching power supply is inserted into the sleeve of the L-shaped bracket. In this way, the switching power supply is installed on the L-shaped bracket. Even if the sleeve column is inserted into the sleeve many times, no wear will occur, thus solving the technical problem in the prior art that the switching power supply installation structure will be unstable due to wear after multiple repairs.

[0007] Furthermore, the L-shaped bracket and the upper end of the switching power supply are provided with a limiting device for limiting the position of the switching power supply.

[0008] By adopting the above technical solution, although the switching power supply is installed on the L-shaped bracket after the sleeve on the switching power supply is inserted into the sleeve of the L-shaped bracket, the setting of the sleeve and the sleeve only limits the freedom of the switching power supply on the L-shaped bracket in the front, back, left and right directions, and does not limit the freedom of the switching power supply on the up and down directions on the L-shaped bracket. This results in that if the house encounters vibration, the switching power supply may be separated from the L-shaped bracket. The limit device set at the upper end of the L-shaped bracket and the switching power supply solves this technical problem.

[0009] Furthermore, the limiting device includes a rotating shaft and a limiting plate, wherein the rotating shaft is fixedly connected to the upper end of the vertical end of the L-shaped bracket, one end of the limiting plate is rotatably connected to the rotating shaft, and the other end extends toward the switching power supply.

[0010] By adopting the above technical solution, the switching power supply is limited in this way. By rotating the limit plate, the limit plate blocks the upper end of the switching power supply, thereby limiting the freedom of the switching power supply to move up and down on the L-shaped bracket, thereby solving the technical problem that the switching power supply may be separated from the L-shaped bracket if the house encounters vibration.

[0011] Furthermore, auxiliary stabilizing devices for further strengthening the connection between the L-shaped bracket and the switching power supply are provided on the front and rear sides of the L-shaped bracket and the front and rear sides of the switching power supply.

[0012] By adopting the above technical solution, an auxiliary stabilizing device is provided to further strengthen the connection between the L-shaped bracket and the switching power supply.

[0013] Furthermore, the auxiliary stabilization device includes a portal frame, a telescopic plate and a fixed plate. The portal frame is fixedly connected to the front and rear sides of the L-shaped bracket. The fixed plates are provided in groups of four, two each, and a gap is left between each group of fixed plates. A group of fixed plates is provided on the front and rear sides of the switching power supply. The telescopic plates have two each, each arranged between two groups of fixed plates and rotatably connected to the fixed plates. A hook is provided at the end of the telescopic plate away from the fixed plate.

[0014] By adopting the above technical solution, the telescopic rods at the front and rear sides of the switch power supply are rotated to make the hooks hook the door-shaped frame, thereby strengthening the connection between the L-shaped bracket and the switch power supply.

[0015] Furthermore, the telescopic plate includes a connecting rod and a hook rod, the connecting rod is provided with an insertion channel, the connecting rod is rotatably connected to the fixed plate, one end of the hook rod is plugged into the connecting rod through the insertion channel, and the other end is provided with a hook, a tightening spring is provided in the insertion channel, one end of the tightening spring is fixedly connected to an end of the insertion channel away from the hook rod, and the other end is fixedly connected to an end of the hook rod inserted in the connecting rod.

[0016] By adopting the above technical solution, the tightening spring can strengthen the force of the hook hooking the portal frame, so that the connection between the L-shaped bracket and the switching power supply is more stable.

[0017] Furthermore, the switch power supply and the upper and lower ends of the L-shaped bracket are provided with fixing devices.

[0018] By adopting the above technical solution, the fixing devices at the upper and lower ends can make the connection between the switching power supply and the L-shaped bracket more stable.

[0019] Furthermore, the L-shaped bracket is made of aluminum alloy.

[0020] By adopting the above technical solution, the bracket made of aluminum alloy is lighter and more convenient to use. In summary, the present application includes at least one of the following beneficial technical effects.

[0021] 1. By setting up the switching power supply, the L-shaped bracket and the fixing device, it is achieved that the sleeve column fixedly connected to the switching power supply is inserted into the sleeve of the L-shaped bracket, so that the switching power supply is installed on the L-shaped bracket. Even if the sleeve column is inserted into the sleeve for many times, no wear will occur, thus solving the technical problem that the switching power supply installation structure will be unstable after being worn out after multiple repairs in the prior art.

[0022] 2. By setting the limit device, it is possible to rotate the limit plate to block the upper end of the switch power supply, thereby limiting the freedom of the switch power supply to move up and down on the L-shaped bracket, thereby solving the technical problem that if the house encounters vibration, the switch power supply may be separated from the L-shaped bracket.

[0023] 3. By setting up the auxiliary stabilizing device, the telescopic rods on both sides of the switching power supply are rotated to make the hook hook the door frame, thereby strengthening the connection between the L-shaped bracket and the switching power supply.
