Anti-drop interface type charger

Abstract

This utility model relates to the field of charger technology, and more particularly to an anti-detachment interface charger, comprising: a charger base, with a plug provided on one side of the charger base. This utility model features an adjustable anti-detachment mechanism. In use, the second limiting frame is pulled out to a suitable position, and the locking block is pulled out to a suitable height, causing the locking block and anti-slip pad to engage with the bottom of the power strip. Then, the second limiting frame and the first limiting frame are released, and the second limiting frame returns to its original position under the action of the second limiting spring, causing the first limiting frame to engage with the outer wall of the power strip. The first telescopic rod moves under the action of the first limiting spring, causing the locking block and anti-slip pad to return to their original position, thus engaging with the anti-slip pad and the bottom of the power strip. This limits the connection between the charger base and the power strip, making it more secure and less prone to detachment. It also avoids poor contact that could lead to malfunctions and makes the charger base easier for the user.

Description

Technical Field

[0001] This utility model relates to the field of charger technology, and in particular to an anti-detachment interface charger. Background Technology

[0002] A charger is a charging device that uses high-frequency power supply technology and advanced intelligent dynamic adjustment charging technology. Chargers (power supply units) can be divided into low-frequency and high-frequency types based on the operating frequency of their circuit design. Low-frequency chargers are designed based on traditional analog circuit principles, and their internal power components (such as transformers, inductors, and capacitors) are relatively large. They generally produce less noise when operating under heavy loads, but this type of charger has stronger resistance to harsh power grid environments, and its reliability and stability are higher than those of high-frequency chargers.

[0003] Currently, chargers have become one of the most common electronic accessories in daily life. Their functions, structures, and appearances have changed significantly with trends and technological innovations. Various novel charger styles have become the focus of attention, and chargers with USB ports are widely used. A search reveals a patent (CN201721640499.8) for an anti-drop charger with USB ports, including a charger base. The bottom of the charger base has a plug, and the top of the charger base is connected to a charging head via a charging cable. The top of the charger base also has a USB interface. Mounting blocks are movably mounted on both the left and right sides of the charger base. The inner side of each mounting block is connected to a vertically positioned elastic rubber rod via a connecting block. The interior of both sides of the charger base has vertically formed slots that mate with the elastic rubber rods, and the outer side of each slot has a vertically formed opening. The bottom of each mounting block has a vertically formed mounting groove, and each mounting groove contains a spring. The tops of the two springs are connected to the tops of the mounting grooves, and the bottoms of the two springs are connected to a bottom limiting plate parallel to the bottom surface of the charger base. The bottom limiting plate has a socket corresponding to the plug position.

[0004] However, while the aforementioned comparative document can provide some anti-drop functionality, its function is relatively simple. Although it can clamp and limit the power strip, thereby fixing the charger and the power strip relatively and preventing it from falling off, its applicability is limited. In particular, power strips now come in various sizes, and their area and thickness vary depending on the number of sockets. The aforementioned comparative document cannot be adapted to these situations, and its shortcomings are quite obvious. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an anti-drop interface charger to solve the problem that although the above-mentioned prior art can play a certain role in preventing drop, its function is relatively simple. Although it can clamp and limit the power strip, thereby fixing the charger and the power strip relatively and thus preventing drop, its applicable range is small. In particular, the size of the power strip varies depending on the number of sockets, and the area and thickness of the power strip also vary. The above-mentioned prior art cannot be adapted to the above situation, and its technical defects are obvious.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A non-detachable interface charger includes: a charger base, a plug on one side of the charger base, and an adjustable anti-detachment mechanism on the inner side of the outer wall of the charger.

[0008] The adjustable anti-detachment mechanism includes a first limiting frame, a second limiting frame, a first telescopic rod, a second telescopic rod, an anti-slip pad, a locking block, a first limiting block, a second limiting block, a first limiting spring, and a second limiting spring. The top end of the first limiting frame is fixedly connected to the second limiting frame, and the bottom end of the first limiting frame is fixedly connected to the locking block. The anti-slip pad is fixedly installed on the top of the locking block. One end of the first telescopic rod is fixedly connected to the locking block, and the other end of the first telescopic rod is fixedly connected to the first limiting block. The first telescopic rod is movably inserted into the interior of the first limiting frame. The first limiting spring is movably sleeved on the outside of the first telescopic rod. One end of the second telescopic rod is fixedly connected to the second limiting block, and the end of the second telescopic rod connected to the second limiting block is movably inserted into the interior of the second limiting frame. The second limiting spring is movably sleeved on the outside of the second telescopic rod.

[0009] Furthermore, a charging cable is provided on the other side of the charger base, and a protective sleeve is provided at the connection between the charging cable and the charger base.

[0010] Furthermore, the outer wall of the charger base has a mounting groove and a plug-in hole. The first limiting frame, the second limiting frame, and the locking block are all movably embedded into the interior of the mounting groove, and the other end of the second telescopic rod is movably inserted into the interior of the charger base.

[0011] Furthermore, the internal thread of the insertion hole is threaded with a bolt, which extends to the inside of one end of the telescopic rod located inside the charger base.

[0012] Furthermore, one end of the limiting spring is engaged with the limiting block, and the other end of the limiting spring is engaged with the inner wall of the limiting frame.

[0013] Furthermore, one end of the second limiting spring is engaged with the second limiting block, and the other end of the second limiting spring is engaged with the inner wall of the second limiting frame.

[0014] The beneficial effects of this utility model are:

[0015] Equipped with an adjustable anti-detachment mechanism, during use, the second limiting frame is pulled out to a suitable position, and the locking block is pulled out to a suitable height, causing the locking block and anti-slip pad to engage with the bottom of the power strip. Then, the second limiting frame and the first limiting frame are released, and the second limiting frame is reset under the action of the second limiting spring, causing the first limiting frame to engage with the outer wall of the power strip. The first telescopic rod moves under the action of the first limiting spring, causing the locking block and anti-slip pad to reset, thus locking the locking block with the anti-slip pad and the bottom of the power strip. This limits the connection between the charger and the power strip, making it more secure and less prone to detachment. It also avoids poor contact that could lead to malfunctions of the charger, making it easier for users to operate. Attached Figure Description

[0026] Please see Figure 1-4 As shown, an anti-detachment interface charger includes: a charger base 1, a plug 2 is provided on one side of the charger base 1, and an adjustable anti-detachment mechanism is provided on the inner side of the outer wall of the charger.

[0027] The adjustable anti-detachment mechanism includes a first limiting frame 5, a second limiting frame 8, a first telescopic rod 13, a second telescopic rod 10, an anti-slip pad 11, a locking block 12, a first limiting block 14, a second limiting block 16, a first limiting spring 15, and a second limiting spring 17. The top of the first limiting frame 5 is fixedly connected to the second limiting frame 8, and the bottom of the first limiting frame 5 is fixedly connected to the locking block 12. The anti-slip pad 11 is fixedly installed on the top of the locking block 12. One end of the first telescopic rod 13 is fixedly connected to the locking block 12, and the other end of the first telescopic rod 13 is fixedly connected to the first limiting block 14. The first telescopic rod 13 is movably inserted into the interior of the first limiting frame 5. The first limiting spring 15 is movably sleeved on the outside of the first telescopic rod 13. One end of the second telescopic rod 10 is fixedly connected to the second limiting block 16, and the end of the second telescopic rod 10 connected to the second limiting block 16 is movably inserted into the interior of the second limiting frame 8. The second limiting spring 17 is movably sleeved on the outside of the second telescopic rod 10.

[0028] Specifically, by setting an adjustable anti-detachment mechanism, during use, the second limiting frame 8 is pulled out to a suitable position, and the locking block 12 is pulled out to a suitable height, so that the locking block 12 and the anti-slip pad 11 are engaged with the bottom of the power strip. Then, the second limiting frame 8 and the first limiting frame 5 are released, and the second limiting frame 8 is reset under the action of the second limiting spring 17, so that the first limiting frame 5 is engaged with the outer wall of the power strip. The first telescopic rod 13 moves under the action of the first limiting spring 15, so that the locking block 12 and the anti-slip pad 11 are reset, so that the locking block 12 is engaged with the anti-slip pad 11 and the bottom of the power strip, thereby limiting the charger holder 1, making the connection between the charger holder 1 and the power strip tighter, preventing detachment, and avoiding poor contact that could cause the charger holder 1 to malfunction, thus facilitating user operation.

[0029] In this embodiment, a charging cable 4 is provided on the other side of the charger base 1, and a protective sleeve 3 is provided on the outside of the connection between the charging cable 4 and the charger base 1.

[0030] Specifically, the charging cable 4 is used for electrical connection between the charger base 1 and the external device. When in use, the plug 2 is inserted into the socket of the power strip. The protective sleeve 3 can prevent the charging cable 4 from being broken and exposed between the charger base 1, which helps to protect the connection between the charging cable 4 and the charger base 1.

[0031] The outer wall of the charger base 1 has a mounting groove 7 and a plug hole 6. The first limiting frame 5, the second limiting frame 8 and the locking block 12 are all movably embedded into the interior of the mounting groove 7. The other end of the second telescopic rod 10 is movably inserted into the interior of the charger base 1. The plug hole 6 has a bolt 9 threaded into its interior and extends to the interior of the end of the second telescopic rod 10 located on the inner side of the charger base 1.

[0032] Specifically, the first limiting frame 5, the second limiting frame 8, and the locking block 12 are all movably embedded into the interior of the mounting slot 7, making the charger base 1 more aesthetically pleasing and practical. This does not affect the normal carrying of the charger base 1, making it more convenient. It also prevents the adjustable anti-detachment mechanism from being damaged by external forces, thus providing a certain degree of protection. At the same time, the second telescopic rod 10 can be detachably installed between itself and the charger base 1 via bolts 9, facilitating repair and replacement in case of damage. It does not require replacing the entire device, making it very convenient to use.

[0033] One end of the limiting spring 15 is engaged with the limiting block 14, and the other end of the limiting spring 15 is engaged with the inner wall of the limiting frame 5. One end of the limiting spring 17 is engaged with the limiting block 16, and the other end of the limiting spring 17 is engaged with the inner wall of the limiting frame 8.

[0034] Specifically, limit block 14 and limit block 2 16 can limit the movement of limit block 14 and limit block 2 16 respectively.

[0035] In summary, compared with existing technologies, this charger has at least the following beneficial effects: By setting an adjustable anti-detachment mechanism, when in use, the second limiting frame 8 is pulled out to a suitable position, and the locking block 12 is pulled out to a suitable height, thereby making the locking block 12 and the anti-slip pad 11 engage with the bottom of the power strip, thereby releasing the second limiting frame 8 and the first limiting frame 5. Then, the second limiting frame 8 is reset under the action of the second limiting spring 17, thereby making the first limiting frame 5 engage with the outer wall of the power strip. The first telescopic rod 13 moves under the action of the first limiting spring 15, thereby making the locking block 12 and the anti-slip pad 11 reset, thereby making the locking block 12 engage with the anti-slip pad 11 and the bottom of the power strip, thus limiting the charger base 1, making the connection between the charger base 1 and the power strip tighter, less prone to detachment, and avoiding poor contact that could cause the charger base 1 to malfunction, thus facilitating user operation.

[0036] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
