Description

Technical Field

[0001] This utility model relates to the field of switching power supply technology, specifically to a switching power supply that is easy to install. Background Technology

[0002] In today's world where modern electronic devices are ubiquitous, switching power supplies play a vital role as an indispensable component of electronic devices. They are power conversion devices that convert AC power, such as mains power, into stable DC power, providing electrical energy that meets the operating requirements of various electronic devices. They are widely used in many fields such as computers, communication equipment, industrial control, and home appliances.

[0003] In the application scenarios of switching power supplies, the ease of installation and disassembly has always been a key factor affecting user experience and maintenance efficiency. Traditional switching power supplies often require multiple tools and complex operating procedures during installation, such as using a screwdriver to tighten multiple screws to fix the main body of the switching power supply. This not only consumes a lot of time and manpower, but also requires a certain level of skill from the operator. During disassembly, there are also many difficulties. Because the traditional installation method makes the connections between the components tight, the screws need to be loosened one by one carefully during disassembly. The slightest carelessness may result in the loss of screws or damage to the casing and internal components of the switching power supply. Moreover, in some environments with limited space or inconvenient operation, traditional installation and disassembly methods are even more difficult to perform, further increasing the difficulty and cost of maintenance. Therefore, those skilled in the art provide a switching power supply that is easy to install to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide a switching power supply that is easy to install, thereby solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a switch power supply that is easy to install, including a U-shaped frame, in which the switch power supply body is slidably sleeved, and a T-shaped groove is provided on the back of the switch power supply body inside the U-shaped frame. Two mounting holes are symmetrically provided on the outer side wall of the switch power supply body, and two sets of mounting mechanisms for quick assembly and disassembly of the switch power supply body are symmetrically provided on the inner side wall of the U-shaped frame. The two sets of mounting mechanisms are inserted into the two mounting holes.

[0006] Preferably, each of the mounting mechanisms includes an inner mounting cylinder fixedly connected to the inner wall of the U-shaped frame. Two guide brackets are symmetrically fixedly connected inside the inner mounting cylinder. A movable rod is provided between the two guide brackets. Two guide strips are symmetrically fixedly connected to the outer wall of the movable rod. The two guide strips are slidably sleeved inside the movable rod. A limit spring is fixedly connected to the end of the movable rod. The end of the limit spring away from the movable rod is fixedly connected to the inner wall of the inner mounting cylinder.

[0007] Preferably, each of the mounting inner cylinders has an opening through its outer wall, and pressure plates are rotatably connected to the inner walls of the two openings on the outer wall of the mounting inner cylinder. The outer wall of the moving rod has two symmetrical inner grooves, and the two pressure plates are placed inside the inner grooves on the side of the moving rod closest to it.

[0008] Preferably, the inner wall of the U-shaped frame is slidably fitted with a wedge block inside the T-slot, the lower end of the wedge block is embedded with an inner bearing, the inner bearing is provided with a threaded rod, the threaded rod is rotatably fitted with the wedge block through the inner bearing, the inner wall of the U-shaped frame is fixedly connected with a positioning block inside the T-slot, the threaded rod is threadedly fitted with the positioning block, and the threaded rod extends to the lower end of the U-shaped frame.

[0009] Preferably, the inner wall of the switching power supply body is symmetrically fixedly connected to two partition plates, and the inner wall of the switching power supply body is symmetrically fixedly connected to four fixing plates between the two partition plates, with each of the mounting inner cylinders located between two fixing plates.

[0010] Preferably, the two pressure plates, which are parallel to the inner cylinder, abut against the outer walls of the two fixed plates, and the angle difference between the end of the pressure plate and the outer wall of the inner cylinder 34 at the minimum tilt angle is between ten and twenty degrees.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model features an installation mechanism. During use, the mounting holes on the outer wall of the power supply body are first aligned with the two inner mounting cylinders. Then, the threaded rod is rotated, causing the wedge block to rise and the two moving rods to compress the limit springs. As the moving rods rise inside the inner mounting cylinders, the two pressure plates, located inside the inner groove, undergo an arc-shaped motion due to the pressure. The angle of the pressure plates gradually becomes parallel to the inner mounting cylinders, and the pressure plates then contact the fixed plate. This method effectively allows for the assembly and disassembly of the power supply body. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Please see Figure 1 - Figure 5 As shown, this utility model provides a technical solution: a switch power supply that is easy to install, including a U-shaped frame 1, a switch power supply body 2 that is slidably sleeved inside the U-shaped frame 1, a T-shaped groove 4 that is opened on the back of the switch power supply body 2 inside the U-shaped frame 1, two mounting holes 21 that are symmetrically opened on the outer side wall of the switch power supply body 2, and two sets of mounting mechanisms 3 that are symmetrically arranged on the inner side wall of the U-shaped frame 1 for quick assembly and disassembly of the switch power supply body 2, the two sets of mounting mechanisms 3 being inserted into the two mounting holes 21.

[0021] It should be noted that the U-shaped frame 1 provides stable support for the overall structure, and its internal sliding sleeve connects to the main body 2 of the switching power supply, making the installation and disassembly process more convenient and smooth. Quick positioning and initial fixation can be achieved without complicated operations. The T-slot 4 is opened inside the U-shaped frame 1 and located on the back of the main body 2 of the switching power supply. It can play a role in precise guidance and auxiliary positioning during installation, further improving the accuracy and efficiency of installation and avoiding installation deviation. During installation, the mounting mechanism 3 can be quickly inserted into the mounting hole 21 to achieve a stable connection between the main body 2 of the switching power supply and the U-shaped frame 1 without the need for additional tools, which greatly shortens the installation time and improves work efficiency. At the same time, this quick disassembly and assembly design also facilitates the subsequent maintenance, replacement or repair of the main body 2 of the switching power supply, reducing maintenance costs.

[0022] As one implementation method in this embodiment, please refer to Figure 3 - Figure 5 As shown, each mounting mechanism 3 includes an inner mounting cylinder 34 fixedly connected to the inner wall of the U-shaped frame 1. Two guide supports 38 are symmetrically fixedly connected inside the inner mounting cylinder 34. A moving rod 35 is positioned between the two guide supports 38. Two guide strips 37 are symmetrically fixedly connected to the outer wall of the moving rod 35. The two guide strips 37 are slidably sleeved inside the moving rod 35. A limit spring 36 is fixedly connected to the end of the moving rod 35. The end of the limit spring 36 away from the moving rod 35 is fixedly connected to the inner wall of the inner mounting cylinder 34. An opening 39 is provided through the outer wall of each inner mounting cylinder 34. The two openings on the outer wall of the inner mounting cylinder 34... The inner walls of the U-shaped frame 1 are rotatably connected to pressure plates 391. The outer wall of the moving rod 35 has two symmetrically opened inner grooves 351. The two pressure plates 391 are placed inside the inner grooves 351 on the side near the moving rod 35. The inner wall of the U-shaped frame 1 is slidably sleeved with a wedge block 31 inside the T-shaped groove 4. The bottom end of the wedge block 31 is embedded with an inner bearing 32. The inner bearing 32 is provided with a threaded rod 33. The threaded rod 33 is rotatably sleeved with the wedge block 31 through the inner bearing 32. The inner wall of the U-shaped frame 1 is fixedly connected with a positioning block 5 inside the T-shaped groove 4. The threaded rod 33 is threadedly sleeved with the positioning block 5, and the threaded rod 33 extends to the bottom end of the U-shaped frame 1.

[0023] It should be noted that during installation, rotating the threaded rod 33 extending to the bottom of the U-shaped frame 1, in thread engagement with the positioning block 5, drives the wedge block 31 to move within the T-slot 4. Since the pressure plate 391 is located inside the inner groove 351 of the outer wall of the moving rod 35, and its movement is facilitated by the up-and-down movement of the moving rod 35, the pressure plate 391 moves in an arc. When the pressure plate 391 is rotated under pressure by the moving rod 35, it will gradually become more parallel. This can be achieved by adjusting the moving rod 35 during installation. The distance inside the inner cylinder 34 allows for adjustment of the angle of the pressure plate 391. During disassembly, the threaded rod 33 is rotated in the opposite direction, causing the wedge block 31 to move in the opposite direction, thus releasing the pressure on the pressure plate 391. As the moving rod 35 descends, the pressure plate 391 can be adjusted, and its angle will change again. With the help of the moving rod 35, the pressure plate 391 will reach its minimum tilt angle, ensuring that the mounting hole 21 on the outer wall of the switching power supply body 2 does not come into contact with the inner cylinder 34 when they are separated.

[0024] As one implementation method in this embodiment, please refer to Figure 5 As shown, two partition plates 22 are symmetrically fixedly connected to the inner wall of the switching power supply body 2, and four fixing plates 23 are symmetrically fixedly connected between the two partition plates 22. Each inner cylinder 34 is located between two fixing plates 23.

[0025] It should be noted that the partition plates 22 are symmetrically distributed, which rationally divides the internal space of the main body 2 of the switching power supply. This effectively isolates circuit areas with different functions, reduces electromagnetic interference between circuits, improves the stability and reliability of the switching power supply, and reduces the failure rate caused by interference. The four fixing plates 23 are symmetrically located between the two partition plates 22, providing a precise and stable installation position for the inner cylinder 34. Each inner cylinder 34 can be placed precisely between two fixing plates 23. During the installation of the main body 2 of the switching power supply to the U-shaped frame 1, the fixing plates 23 can provide good limiting and support for the inner cylinder 34, preventing the inner cylinder 34 from shifting during installation, ensuring that the installation mechanism 3 can be accurately inserted into the installation hole 21, and improving the accuracy and success rate of installation.

[0026] As one implementation method in this embodiment, please refer to Figure 3 - Figure 5 As shown, the two pressure plates 391, which are parallel to the inner cylinder 34, abut against the outer walls of the two fixed plates 23. At the minimum tilt angle, the angle difference between the end of the pressure plate 391 and the outer wall of the inner cylinder 34 is between ten and twenty degrees.

[0027] It should be noted that when the pressure plate 391 is parallel to the inner cylinder 34 and abuts against the outer walls of the two fixing plates 23, it can effectively enhance the stability of the connection between the power supply body 2 and the U-shaped frame 1. During installation, this parallel abutment state makes the pressure plate 391 and the fixing plate 23 fit tightly together, forming a stable support structure. This can prevent the power supply body 2 from shaking or shifting within the U-shaped frame 1, ensuring the reliability of the installation and reducing noise and potential failure risks caused by loosening. When disassembly is required, simply operate the pressure plate 391 to reach the minimum tilt angle. At this time, the force between the pressure plate 391 and the fixing plate 23 changes, making it easier to detach from the outside of the fixing plate 23, facilitating the disassembly process and saving disassembly time and manpower.

[0028] Working principle: When in use, first slide the main body 2 of the switching power supply into the U-shaped frame 1, so that the two mounting holes 21 on its outer side wall are connected with the two sets of mounting inner cylinders 34 on the inner side wall of the U-shaped frame 1. At this time, each mounting inner cylinder 34 is located between the two fixing plates 23 between the two partition plates 22 on the inner side wall of the main body 2 of the switching power supply. Then, rotate the threaded rod 33 that extends to the bottom of the U-shaped frame 1. The threaded rod 33 is threadedly engaged with the positioning block 5, which drives the wedge block 31 with the inner bearing 32 embedded to move upward in the T-shaped groove 4. When the wedge block 31 rises, it squeezes the two moving rods 35, and the moving rods 35 will compress the limit spring 36. At this time, the moving rods 35 are in an upward trend. Since the pressure plate 391 is located inside the inner groove 351, under the abutment of the moving rods 35, the pressure plate 391, which was originally located in the inner groove 351 of the moving rods 35, moves in an arc due to the squeezing force.

[0029] Simultaneously, under the guidance of the guide bracket 38 and the guide bar 37, the moving rod 35 compresses the limiting spring 36 and moves upward. The angle of the pressure plate 391 gradually becomes parallel to the mounting inner cylinder 34, and finally abuts against the outer walls of the two fixed plates 23, thus achieving a stable installation of the switching power supply body 2. During disassembly, the threaded rod 33 is rotated in the opposite direction, the wedge block 31 descends, the moving rod 35 moves downward, and is assisted in resetting under the action of the limiting spring 36. As the moving rod 35 moves downward, the pressure plate 391 gradually returns to its minimum tilt angle, and its end is inclined to the outer wall of the mounting inner cylinder 34, making it easy to detach from the outside of the fixed plate 23. At this time, the switching power supply body 2 can be easily removed.

[0030] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
