Description

Technical Field

[0001] This utility model relates to the field of switching power supplies, and specifically to a switching power supply with a shock-absorbing and fixing structure. Background Technology

[0002] A switching power supply is a high-frequency power conversion device, a type of power supply. Its function is to convert a voltage at a certain level into the voltage or current required by the user through different architectures.

[0003] A search revealed a utility model DC switching power supply protection mechanism with announcement number CN219304688U, comprising a switching power supply body. The upper and lower outer surfaces of the switching power supply body are provided with heat dissipation grooves, and multiple fixing sleeves are fixedly installed on both the upper and lower outer surfaces of the switching power supply body. Protective side plates are fixedly installed at both ends of the protective shell, and the protective side plates are far apart from the switching power supply body. A spring in the inner cavity of the fixing sleeve allows the buffer rod to extend and retract, reducing the buffering force when the protective shell collides with external objects, thereby protecting the switching power supply body from damage. Simultaneously, multiple heat dissipation holes are provided on the outer surface of the protective shell without affecting the heat dissipation of the switching power supply body, and dustproof meshes are fixedly installed in the multiple heat dissipation holes, serving to prevent dust and debris from entering the interior of the switching power supply body.

[0004] Existing switching power supplies lack shock-absorbing and fixing structures. When subjected to external impacts or vibrations, their internal structures are easily damaged, leading to loosening, disintegration, or detachment of components. This not only affects the normal operation of the switching power supply but may also cause short circuits and reduce its electrical performance. In the comparative case above, the DC switching power supply protection mechanism achieves protection through a protective shell and a buffer rod. However, simply relying on the shell and buffer rod is not effective in buffering and shock absorption when subjected to external impacts or vibrations, which can also lead to loosening of components.

[0005] Therefore, it is necessary to invent a switching power supply with a shock-absorbing and fixing structure to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a switching power supply with a shock-absorbing and fixing structure. The switching power supply body is placed inside a protective shell, and the clamps on both sides and multiple first damping springs on the rear side provide a buffering and shock-absorbing effect. Simultaneously, the shock-absorbing mechanisms on both sides of the rear of the switching power supply body enhance its overall shock resistance. When the switching power supply body is subjected to impact, it will drive the first and second fixed seats and the internal sliding rod, causing the second damping springs outside the sliding rod to compress and move the buffer moving sleeve. As the two sets of moving sleeves move, they push the movable rod to move on the fixed block inside the protective shell, thereby damping the switching power supply body. This solves the problem in the aforementioned comparative case of DC switching power supply protection mechanisms mentioned in the background art, which achieve protection through a protective shell and buffer rod. However, simply relying on the shell and buffer rod is insufficient to effectively buffer and absorb shock when subjected to external impact or vibration, potentially leading to loosening of parts.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a switching power supply with a shock-absorbing and fixing structure, comprising a switching power supply body;

[0008] A protective shell is installed outside the main body of the switching power supply for protection. Limiting plates are slidably connected inside both sides of the protective shell, and limiting mechanisms are fixedly installed on both sides of the top of the protective shell. Mounting blocks are fixedly connected around the perimeter of the protective shell.

[0009] The clamping plates are set on both sides inside the protective shell. A first damping spring is fixedly installed on both sides inside the protective shell. The rear side of the clamping plate is fixedly connected to the clamping plate.

[0010] A shock-absorbing mechanism is installed on the rear side of the main body of the switching power supply and the inner side of the protective shell for shock absorption. The shock-absorbing mechanism includes a fixed block, a movable sleeve, and a second damping spring.

[0011] Preferably, the limiting mechanism includes a fixed cylinder, which is fixedly installed on both sides above the protective shell. A rod is slidably connected inside the fixed cylinder. A pull ring is fixedly installed at the upper end of the rod. A top block is fixedly connected to the outside of the rod. A tension spring is provided above the top block and outside the rod.

[0012] Preferably, slots are provided on both sides of the upper part of the limiting plate, and the insertion rod is movably engaged with the slots on the upper part of the limiting plate.

[0013] Preferably, a bolt passes through the interior of the mounting block, and a buffer sleeve is fitted on the upper outer side of the bolt. The outer diameter of the bolt is smaller than the diameter of the internal slot of the mounting block.

[0014] Preferably, the fixing block is fixedly installed inside the protective shell on both sides, and movable rods are movably sleeved on the upper sides of the fixing block. The movable sleeve is movably sleeved with the other end of the movable rod, and a sliding rod is slidably connected inside the movable sleeve. The second damping spring is movably sleeved on the outside of the sliding rod.

[0015] Preferably, a first fixing seat and a second fixing seat are fixedly connected to the front and rear sides of the slide rod, and the first fixing seat and the second fixing seat are respectively fixed to the rear sides of the switching power supply body.

[0016] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0017] 1. By setting up the main body of the switching power supply, the protective shell, the first damping spring, the clamping plate and the shock absorption mechanism, the overall shock resistance of the switching power supply is improved. When the switching power supply is placed in the protective shell, the clamping plates on both sides and the multiple first damping springs on the rear side buffer and absorb shock. At the same time, the shock absorption mechanisms on both sides of the rear side of the switching power supply further enhance the overall shock resistance of the switching power supply. When the switching power supply is subjected to impact, it will drive the first fixed seat, the second fixed seat and the internal sliding rod, so that the second damping spring outside the sliding rod squeezes the buffer moving sleeve to move. When the two sets of moving sleeves move, they push the movable rod to move on the fixed block inside the protective shell, thereby absorbing shock for the switching power supply.

[0018] 2. By setting up the limiting plate and limiting mechanism, the main body of the switching power supply inside the protective shell can be limited and the fixation can be strengthened. After the main body of the switching power supply is placed inside the protective shell, the plug rod is pulled to squeeze the tension spring, so that the plug rod is disengaged from the slot outside the limiting plate. Then the limiting plate is pushed to limit the main body of the switching power supply. After that, the plug rod is released and the external tension spring rebounds, inserting the plug rod into the slot inside the limiting plate to limit and fix it. Attached Figure Description

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] This utility model provides, for example Figure 1-7 The switch power supply shown has a shock-absorbing and fixing structure, including a switch power supply body 1;

[0031] The protective shell 2 is set outside the main body 1 of the switching power supply for protection. The protective shell 2 has a limit plate 3 slidably connected inside both sides. The upper two sides of the protective shell 2 are fixedly provided with limit mechanisms 4. The protective shell 2 is fixedly connected with mounting blocks 7 around its perimeter.

[0032] The clamping plate 6 is set on both sides inside the protective shell 2. The first damping spring 5 is fixedly installed on both sides inside the protective shell 2. The rear side of the clamping plate 6 is fixedly connected to the clamping plate 6.

[0033] The shock absorption mechanism 10 is installed on the rear side of the switching power supply body 1 and the inner side of the protective shell 2 for shock absorption. The shock absorption mechanism 10 includes a fixed block 1001, a movable sleeve 1003 and a second damping spring 1005. The switching power supply body 1 is placed inside the protective shell 2. The clamps 6 on both sides and the multiple first damping springs 5 ​​on the rear side provide a buffering and shock absorption effect for the switching power supply body 1. At the same time, the shock absorption mechanisms 10 on both sides of the rear side of the switching power supply body 1 enhance the overall shock resistance of the switching power supply body 1. When the switching power supply body 1 is subjected to impact force, it will drive the first fixed seat 1006 and the second fixed seat 1007 and the internal slide rod 1004, so that the second damping spring 1005 outside the slide rod 1004 squeezes the buffer movable sleeve 1003 to move. When the two sets of movable sleeves 1003 move, they push the movable rod 1002 to move on the fixed block 1001 on the inner side of the protective shell 2, thereby absorbing the shock of the switching power supply body 1.

[0034] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the limiting mechanism 4 includes a fixed cylinder 401, which is fixedly installed on both sides above the protective shell 2. A rod 402 is slidably connected inside the fixed cylinder 401. A pull ring 403 is fixedly installed at the upper end of the rod 402. A top block 404 is fixedly connected to the outside of the rod 402. A tension spring 405 is provided above the top block 404 and outside the rod 402. By pulling the rod 402, the rod 402 is pushed to compress the tension spring 405, causing the rod 402 to disengage from the slot outside the limiting plate 3. Then, the limiting plate 3 is pushed to limit the rod 402 above the switching power supply body 1. After that, the rod 402 is released and the external tension spring 405 rebounds, inserting the rod 402 into the slot inside the limiting plate 3 for limiting and fixing.

[0035] like Figure 2 and Figure 3 As shown, slots are provided on both sides of the upper part of the limiting plate 3. The insertion rod 402 is movably engaged with the slot on the upper part of the limiting plate 3. By inserting the insertion rod 402 into the slot on the upper part of the limiting plate 3, the limiting plate 3 can be fixed and positioned, thereby enhancing the stability of the limiting plate 3 and the internal switching power supply body 1 of the protective shell 2.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, a bolt 8 passes through the interior of the mounting block 7, and a buffer sleeve 9 is fitted on the upper side of the bolt 8. The outer diameter of the bolt 8 is smaller than the diameter of the internal hole of the mounting block 7. Through the bolt 8 and the external buffer sleeve 9 passing through the mounting block 7, not only can the entire protective shell 2 be fixed, but the internal hole of the mounting block 7 is also larger than the bolt 8, so that the external buffer sleeve 9 can play a shock-absorbing and buffering role inside the mounting block 7.

[0037] like Figure 5 and Figure 6 As shown, the fixing block 1001 is fixedly installed inside the protective shell 2 on both sides. The upper sides of the fixing block 1001 are movably sleeved with the movable rod 1002. The movable sleeve 1003 is movably sleeved with the other end of the movable rod 1002. The movable sleeve 1003 is slidably connected to the slide rod 1004 inside. The second damping spring 1005 is movably sleeved on the outside of the slide rod 1004. When the switching power supply body 1 is subjected to an impact force, it will drive the first fixing seat 1006 and the second fixing seat 1007 and the slide rod 1004 inside, so that the second damping spring 1005 outside the slide rod 1004 squeezes and buffers the movable sleeve 1003 to move. When the two sets of movable sleeves 1003 move, they push the movable rod 1002 to move on the fixing block 1001 inside the protective shell 2, thereby absorbing the shock of the switching power supply body 1.

[0038] like Figure 5 and Figure 6 As shown, the first fixing seat 1006 and the second fixing seat 1007 are fixedly connected to the front and rear sides of the slide rod 1004. The first fixing seat 1006 and the second fixing seat 1007 are respectively fixed to the rear sides of the switching power supply body 1. The first fixing seat 1006 and the second fixing seat 1007 are fixed to the rear sides of the switching power supply body 1 to enhance the fixation and shock absorption effect between the switching power supply body 1 and the shock absorption mechanism 10.

[0039] The working principle of this utility model is as follows: First, the main body 1 of the switching power supply is installed inside the protective shell 2. The clamps 6 on both sides inside the protective shell 2 are tightly attached to both sides of the main body 1 of the switching power supply. Then, the pull rings 403 on both sides of the top of the protective shell 2 are pulled to drive the plug rod 402 to compress the tension spring 405, causing the plug rod 402 to disengage from the slot outside the limiting plate 3. Then, the limiting plate 3 is pushed to limit the switching power supply main body 1. After that, the plug rod 402 is released, and the external tension spring 405 rebounds, inserting the plug rod 402 into the slot inside the limiting plate 3 for limiting and fixing. Then, the protective shell 2 is installed in the designated position, and the bolts 8 and the external buffer sleeve 9 pass through the mounting block 7 to limit and fix the entire protective shell 2. When the switching power supply main body 1 and the protective shell 2 are subjected to external impact or vibration during use, the protective shell 2 will be fixed. When in operation, the clamping plates 6 on both sides of the main body 1 and the multiple first damping springs 5 ​​on the rear side provide a buffering and shock-absorbing effect for the main body 1. The shock-absorbing mechanisms 10 on both sides of the rear side of the main body 1 enhance the overall shock resistance of the main body 1. When the main body 1 is subjected to impact, it will drive the first fixed seat 1006, the second fixed seat 1007 and the internal slide rod 1004, causing the second damping spring 1005 outside the slide rod 1004 to compress the buffer moving sleeve 1003 and move it. When the two sets of moving sleeves 1003 move, they push the movable rod 1002 to move on the fixed block 1001 inside the protective shell 2, thereby absorbing the shock of the main body 1. In this way, the use of the switching power supply with shock-absorbing and fixing structure is completed.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
