Description

Technical Field

[0001] This utility model relates to the field of power adapter technology, specifically a power adapter with an external fixing rod. Background Technology

[0002] A power adapter is a power supply device that provides compatible power to electronic devices. It usually exists as an independent external module. Its core function is to convert the daily mains power into the specific low-voltage power (mostly DC, and a few AC of a specific frequency) required by the device through internal rectification, filtering, and voltage regulation circuits. At the same time, it has the function of stabilizing the output voltage and current, which can avoid damage to the device caused by mains power fluctuations.

[0003] Traditional power adapters are heavy and prone to coming loose and falling due to gravity or cable pulling. While existing solutions with added fixing rods can provide support, the fixed length of the rods cannot adapt to different usage environments, resulting in poor versatility and the continued existence of support failure or installation problems. Utility Model Content

[0004] The purpose of this invention is to provide a power adapter with an external fixing rod to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a power adapter with an external fixing rod, comprising a power adapter body, a connecting mechanism on the back of the power adapter body, an extension mechanism on the back of the connecting mechanism, and a mounting plate on the back of the extension mechanism; The extension mechanism includes a support base disposed on the back of the connecting mechanism. A T-shaped block is rotatably connected inside the support base. A knob is threadedly connected to the outer wall of the T-shaped block. A support block is fixedly connected to the outer wall of the T-shaped block. A sliding cylinder is fixedly connected to the back of the support block. A fixed arm is fixedly connected to the outer wall of the sliding cylinder. A rectangular box is fixedly connected to the inner side of the fixed arm. A threaded rod is rotatably connected inside the rectangular box. A threaded block is threadedly connected to the outer wall of the threaded rod. A short shaft is fixedly connected to the bottom of the threaded block. A connecting block is fixedly connected to the bottom of the short shaft. An arc-shaped block is fixedly connected to the bottom of the connecting block. A plug shaft is fixedly connected to one side of the arc-shaped block. A sliding shaft is slidably connected to the inner wall of the sliding cylinder. A knob is fixedly connected to one end of the threaded rod.

[0006] Preferably, the sliding shaft is fixedly connected to the inside of the mounting plate, and the threaded block is slidably connected to the inner wall of the rectangular box, so that the threaded block can move stably.

[0007] Preferably, the outer wall of the sliding cylinder is fixedly connected with a movable hole, and the insertion shaft passes through the movable hole, so that the insertion shaft can move through the movable hole.

[0008] Preferably, the outer wall of the sliding shaft has six locking holes, and the insert shaft is movably connected to the inner wall of one of the six locking holes, so that the insert shaft can limit the sliding shaft through the locking hole.

[0009] Preferably, the bottom of the rectangular box has a slot, through which the short shaft passes, allowing the short shaft to move.

[0010] Preferably, the connecting mechanism includes a fixing groove, which is fixedly connected to the back of the power adapter body. A protrusion is slidably connected to the inner wall of the fixing groove, and a bolt is threadedly connected inside the protrusion. A knob is fixedly connected to the outer wall of the bolt to facilitate the disassembly of the extension mechanism.

[0011] Preferably, the protrusion is fixedly connected to the front of the support base, and the inner side of the second knob is in close contact with the outer side of the support base, so that the second knob can press and limit the support base.

[0012] Preferably, a circular hole is provided on the outer side of the fixing groove, and the bolt passes through the circular hole, so that the bolt can move through the circular hole.

[0013] Compared with the prior art, the present invention provides a power adapter with an external fixing rod, which has the following advantages: 1. This power adapter with an external fixing rod, through its extension mechanism, achieves multi-dimensional stepless adjustment of the support length and angle. Rotating knob three precisely controls the threaded rod mechanism, driving the insertion shaft to accurately engage with the sliding shaft at different positions of the locking holes, achieving flexible length locking and robust support. Rotating knob two easily adjusts and locks the angle of the support base, ensuring the mounting plate reliably presses against walls of varying depths. This adjustment method is structurally stable, easy to operate, and completely solves the problem of support failure caused by differences in installation environments.

[0014] 2. This power adapter with an external fixing rod features a connection mechanism that allows for quick assembly and disassembly of the extension mechanism from the power adapter body. Users can easily insert the protrusion into the fixing slot and tighten the screw with a knob to complete the installation, and vice versa.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] This utility model provides the following technical solution: Example 1 Combination Figures 1 to 5A power adapter with an external fixing rod includes a power adapter body 1, a connecting mechanism 3 on the back of the power adapter body 1, an extension mechanism 2 on the back of the connecting mechanism 3, and a mounting plate 4 on the back of the extension mechanism 2. This structure integrates the connecting mechanism 3 and the extension mechanism 2 onto the power adapter body 1 through a modular design, so that the adapter can obtain stable support through the mounting plate 4 while maintaining a compact structure, thus solving the fundamental problem that traditional adapters are prone to falling off the socket due to their top-heavy design. The extension mechanism 2 includes a support base 21, which is located on the back of the connecting mechanism 3. A T-shaped block 23 is rotatably connected inside the support base 21. A knob 24 is threadedly connected to the outer wall of the T-shaped block 23. A support block 22 is fixedly connected to the outer wall of the T-shaped block 23. A sliding cylinder 25 is fixedly connected to the back of the support block 22. A fixed arm 26 is fixedly connected to the outer wall of the sliding cylinder 25. A rectangular box 27 is fixedly connected to the inner side of the fixed arm 26. A threaded rod 28 is rotatably connected inside the rectangular box 27. A threaded block 29 is threadedly connected to the outer wall of the threaded rod 28. A short shaft 201 is fixedly connected to the bottom of the threaded block 29. The extension mechanism 2 is fixedly connected to a connecting block 202 at one end, and an arc-shaped block 203 is fixedly connected to the bottom of the connecting block 202. An insert shaft 204 is fixedly connected to one side of the arc-shaped block 203. A sliding shaft 206 is slidably connected to the inner wall of the sliding cylinder 25. A knob 3 205 is fixedly connected to one end of the threaded rod 28. This extension mechanism 2 integrates dual adjustment functions of angle and length. The support angle can be adjusted by controlling the rotation of the T-shaped block 23 through the knob 24. The length can be adjusted and locked by driving the threaded rod 28 to move the insert shaft 204 through the knob 3 205. The structure is ingenious, the operation is simple, and it can effectively adapt to various complex installation environments.

[0020] Furthermore, the sliding shaft 206 is fixedly connected to the inside of the mounting plate 4, and the threaded block 29 is slidably connected to the inner wall of the rectangular box 27. This structure ensures that the threaded block 29 can only perform stable linear motion within the rectangular box 27, thereby accurately converting the rotational motion of the threaded rod 28 into the linear motion of the insert shaft 204, preventing motion interference, and improving the reliability and durability of the length adjustment mechanism.

[0021] Furthermore, the outer wall of the sliding cylinder 25 is fixedly connected with a moving hole, through which the insertion shaft 204 passes. The moving hole provides precise motion guidance and limit for the insertion shaft 204, ensuring that the insertion shaft 204 can accurately align with different locking holes on the sliding shaft 206 during movement, thus achieving fast and reliable locking and unlocking and improving the user experience.

[0022] Furthermore, the outer wall of the sliding shaft 206 has six locking holes. The insertion shaft 204 is movably connected to the inner wall of one of the six locking holes. The six locking holes provide multiple length adjustment options. Users can insert the insertion shaft 204 into different locking holes according to actual needs to obtain different support lengths, which greatly enhances the adaptability of the fixing rod to different socket depths and installation spaces.

[0023] Furthermore, a slot is provided at the bottom of the rectangular box 27, through which the short shaft 201 passes. The design of the slot allows the short shaft 201 to drive the connecting block 202 and the arc block 203 below it to move linearly together with the threaded block 29. At the same time, the slot limits the range of motion of the short shaft 201, ensuring the stability and consistency of the entire transmission mechanism.

[0024] Example 2 See Figures 1 to 5 Furthermore, based on Embodiment 1, the connecting mechanism 3 further includes a fixing groove 31, which is fixedly connected to the back of the power adapter body 1. A protrusion 32 is slidably connected to the inner wall of the fixing groove 31, and a bolt 33 is threadedly connected inside the protrusion 32. A knob 34 is fixedly connected to the outer wall of the bolt 33. This connecting mechanism 3 achieves quick installation and separation of the extension mechanism 2 and the power adapter body 1 by simply sliding and inserting the protrusion 32 with the fixing groove 31 and the threaded locking bolt 33. This allows users to flexibly choose whether to install a support rod according to the actual usage scenario, improving the versatility and portability of the product.

[0025] Furthermore, the protrusion 32 is fixedly connected to the front of the support base 21, and the inner side of the knob 24 is in contact with the outer side of the support base 21. By tightening the knob 24, its inner side presses against the outer surface of the support base 21, and the relative angle between the T-shaped block 23 and the support base 21 can be firmly locked by friction, thus achieving reliable fixation after stepless adjustment of the support angle and ensuring the stability of the support state.

[0026] Furthermore, a round hole is provided on the outer side of the fixing groove 31, through which the bolt 33 passes. The round hole provides a path for the bolt 33 to pass through, ensuring that when the knob 34 is rotated externally, the bolt 33 can be smoothly screwed into the threaded hole inside the protrusion 32, thereby completing the tightening and fixing of the protrusion 32 inserted into the fixing groove 31. The operation is simple and the connection is firm.

[0027] In actual operation, when this device is used, the protrusion 32 is inserted into the inner wall of the fixing groove 31 to provide initial support. Then, the bolt 33 is screwed into the inside of the protrusion 32 by the knob 34 to limit the position of the protrusion 32, thereby achieving the purpose of installation and connection of the protrusion 32. Similarly, the power adapter body 1 and the extension mechanism 2 can be disassembled, so that the power adapter body 1 can be used in scenarios where the extension mechanism 2 is not required.

[0028] Rotating knob 205 drives the threaded rod 28 to rotate. Since the threaded rod 28 and the threaded block 29 are threadedly connected, and the threaded block 29 can slide and limit the movement of the threaded rod 28 on the inner wall of the rectangular box 27, the rotational motion of the threaded rod 28 is converted into the linear motion of the threaded block 29. The threaded block 29 can drive the connecting block 202 to move through the short shaft 201. The connecting block 202 can drive the insert shaft 204 to be pulled out from the inside of the sliding shaft 206 through the arc block 203, thus removing the limitation on the sliding shaft 206. Then the sliding shaft 206 can slide out from the inner wall of the sliding cylinder 25. After adjusting to the appropriate length, knob 205 can be rotated in the opposite direction to achieve the purpose of fixing. Rotating knob 24 will prevent knob 24 from pressing against the support seat 21, thereby adjusting the installation angle of the extension mechanism 2, which is suitable for different usage environments.
