Description

Technical Field

[0001] The utility model belongs to the technical field of switching power supplies, and particularly relates to a switching power supply convenient for assembly. Background Technique

[0002] A switching power supply is a power supply that uses modern power electronics technology to control the on-off time ratio of a switching tube to maintain a stable output voltage. It rectifies and filters the input alternating current, converts it into direct current, and then uses the fast on-off of high-frequency switching devices (such as MOSFET tubes) to chop the direct current into high-frequency pulses. After voltage transformation by a transformer and rectification and filtering, the required direct current voltage is finally output. The switching power supply has the advantages of high efficiency, small size, light weight, wide voltage regulation range, etc. For example, it is widely used in many electronic devices such as computers, mobile phone chargers, and industrial automation equipment. Compared with traditional linear power supplies, it can significantly reduce energy consumption and equipment volume.

[0003] When assembling the existing switching power supply, the assembly process is rather cumbersome, time-consuming and laborious for users, and the assembly process is not convenient and efficient enough. When the switching power supply is damaged due to a fault during use, its disassembly process is not simple enough, which affects the use of the device.

After installation, rotate the knob to fix it, and clamp the clamping column in the lower connecting block, making its assembly process more convenient and efficient. And when there is a fault in the internal components of the switching power supply, it can be quickly opened for maintenance, improving the applicability of the device.

[0005] In view of the above problems, although the existing patent can simplify the assembly and disassembly of the switching power supply to a certain extent, in the actual disassembly and assembly process, it is still difficult to directly disassemble and assemble the switching power supply, which will inevitably affect the efficiency of assembly and maintenance and repair, and it is necessary to improve this. Therefore, a switching power supply convenient for assembly is proposed. Content of the Utility Model

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0024] Please refer to Figure 1-7 , the present utility model provides a technical solution:

[0025] A switch power supply convenient for assembly, comprising a lower housing 1 and an upper housing 2. The upper housing 2 is slidably arranged on the top of the lower housing 1. Installation blocks 3 are fixedly installed on both sides of the upper housing 2. Symmetrical movable rods 4 are rotatably arranged on the two groups of installation blocks 3. Plug blocks 5 are rotatably arranged at the bottom ends of the movable rods 4. Cross plates 6 are fixedly installed on both sides of the lower housing 1. Slideways 7 are formed on the two groups of cross plates 6, and sockets 8 are formed at both ends of the slideways 7 in the two groups of cross plates 6. The sockets 8 are communicated with the slideways 7. The size of the plug block 5 is adapted to the size of the socket 8. A fixing member 9 for fixing the upper housing 2 on the lower housing 1 is arranged on the plug block 5 and the cross plate 6. The fixing member 9 includes an installation opening 91 formed on the cross plate 6 at the side of the socket 8, a spring 92 arranged in the installation opening 91, a fixing block 93 slidably arranged on the installation opening 91, and a fixing opening 94 formed on the side of the plug block 5. The spring 92 is pressed between the cross plate 6 and the fixing block 93. The fixing block 93 and the fixing opening 94 are arranged as arc surfaces adapted to each other.

[0026] In the switch power supply convenient for assembly, the lower housing 1 is the basic part. The switch power supply is installed in the lower housing 1. The installation blocks 3 fixedly installed on both sides of the upper housing 2 are used to install the movable rods 4. The movable rods 4 can deflect on the installation blocks 3. The plug blocks 5 rotatably arranged at the bottom ends of the movable rods 4 cooperate with the cross plates 6 fixedly installed on both sides of the lower housing 1. The slideways 7 formed on the cross plates 6 and the sockets 8 communicated with both ends thereof provide a path for the movement and insertion of the plug blocks 5.

[0027] When the upper housing 2 needs to be installed on the lower housing 1, the operator first inserts the upper housing 2 on the top of the lower housing 1 and slides it to a proper position, then rotates the movable rods 4 and the plug blocks 5 respectively to align the plug blocks 5 with the slideways 7, and then continues to move the upper housing 2 downward, so that the plug blocks 5 move along the slideways 7, the movable rods 4 deflect, and the plug blocks 5 are inserted into the sockets 8. When the plug blocks 5 are inserted into the sockets 8, under the action of the spring 92, the fixing blocks 93 are clamped into the fixing openings 94 formed on the sides of the plug blocks 5, thereby firmly fixing the upper housing 2 on the lower housing 1.

[0028] When the lower housing 1 and the upper housing 2 need to be disassembled, the operator only needs to hold the movable rods 4 on both sides of the housing with both hands and contract them, which can drive the fixing blocks 93 to be compressed by the acting force to disengage from the fixing openings 94 by compressing the spring 92, and then the plug blocks 5 can quickly disengage from the sockets 8, and then the lower housing 1 and the upper housing 2 are slid and disassembled.

[0029] This switch power supply can realize the simple disassembly and assembly of the upper housing 2 and the lower housing 1. The disassembly and assembly process is rapid, which not only significantly improves the assembly efficiency, reduces the cumbersome steps in the assembly process, but also facilitates the subsequent maintenance and upgrade work, thus bringing a more convenient and efficient use experience to users.

[0030] Two sets of symmetric torsion springs 10 are fixedly installed inside the two sets of the mounting blocks 3, and the two ends of the torsion springs 10 are respectively fixedly installed on the mounting blocks 3 and the rotating shaft ends of the movable rods 4;

[0031] When the movable rod 4 is rotated for the assembly or disassembly operation of the upper shell 2 and the lower shell 1, the torsion springs 10 will generate corresponding torques. During assembly, the torque of the torsion springs 10 helps to keep the position of the movable rod 4 stable, so that the insertion block 5 can be accurately inserted into the socket 8. During disassembly, the torque of the torsion springs 10 can assist the rotation of the movable rod 4, making the operation easier and more convenient.

[0032] Grip rods 11 are fixedly installed in the middle of multiple sets of the movable rods 4, and rubber pads are sleeved on the outer walls of the grip rods 11;

[0033] The grip rods 11 fixedly installed in the middle of multiple sets of the movable rods 4 provide a force application part for the operator. The rubber pads sleeved on the outer walls of the grip rods 11 can increase the friction force, making the operator more comfortable and stable when holding the grip rods 11.

[0034] A damping is provided at the rotational connection of the insertion block 5 and the movable rod 4;

[0035] It can prevent the insertion block 5 from deflecting randomly, and further facilitate the installation between the lower shell 1 and the upper shell 2.

[0036] Working principle:

[0037] In the switch power supply that is easy to assemble, the lower shell 1 is used as the basic part, and the switch power supply is installed inside the lower shell 1. The mounting blocks 3 fixedly installed on both sides of the upper shell 2 are used to install the movable rods 4. The movable rods 4 can deflect on the mounting blocks 3. The insertion blocks 5 rotatably arranged at the bottom ends of the movable rods 4 cooperate with the cross plates 6 fixedly installed on both sides of the lower shell 1. The slideways 7 opened on the cross plates 6 and the sockets 8 communicated with both ends thereof provide a path for the movement and insertion of the insertion blocks 5;

[0038] When it is necessary to install the upper shell 2 on the lower shell 1, the operator first inserts the upper shell 2 on the top of the lower shell 1 and slides it to a suitable position, and then rotates the movable rods 4 and the insertion blocks 5 respectively to make the insertion blocks 5 face the slideways 7. Then, the upper shell 2 is moved downward continuously, so that the insertion blocks 5 move along the slideways 7, the movable rods 4 deflect, and the insertion blocks 5 are inserted into the sockets 8. When the insertion blocks 5 are inserted into the sockets 8, under the action of the spring 92, the fixing block 93 is snapped into the fixing openings 94 opened on the sides of the insertion blocks 5, thereby firmly fixing the upper shell 2 on the lower shell 1;

[0039] When it is necessary to disassemble the lower housing 1 and the upper housing 2, the operator only needs to hold the two sides of the housing with both hands and contract the movable rod 4, which can drive the fixing block 93 to compress the spring 92 under the action force and disengage from the fixing port 94, so that the insertion block 5 quickly disengages from the insertion port 8, and then slide and disassemble the lower housing 1 and the upper housing 2;

[0040] This switching power supply can achieve the simple disassembly and assembly of the upper housing 2 and the lower housing 1. The disassembly and assembly process is rapid, which not only significantly improves the assembly efficiency, reduces the cumbersome steps in the assembly process, but also facilitates the subsequent maintenance and upgrade work, thus bringing a more convenient and efficient use experience to users.

[0041] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
