Description

Technical Field

[0001] This utility model relates to the field of plug technology, and in particular to a plug with a locking mechanism. Background Technology

[0002] The connectors of general electronic products and the pins of electrical appliances are called plugs; household AC power plugs and sockets are male connectors with protruding rods or copper plates that are physically inserted into female connectors with slots or recesses; size is an important technical requirement that is related to whether plugs, sockets and converters can be used safely and whether they meet universal interchangeability requirements to avoid misinsertion; non-compliant size will affect the user's use or cause poor contact, misinsertion and other hidden dangers, which may cause equipment damage or even fire and electric shock accidents.

[0003] Existing plugs lack a locking mechanism, making them susceptible to loosening, slippage, or falling off due to external forces after being plugged into power strips, sockets, or other objects. This can lead to sudden power outages and compromise the stability of electrical equipment during operation. We propose a plug with a locking mechanism to address these issues. Utility Model Content

[0004] The purpose of this invention is to provide a locking plug to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A locking plug includes a socket. A limiting shell is fixedly connected to the front of the socket. A plug body is provided inside the limiting shell. A groove is formed on both the upper and lower surfaces of the plug body. An elastic plate and a spring are fixedly connected inside the groove. A through groove is formed on both the upper and lower surfaces of the limiting shell. A limiting plate is provided inside the through groove. A limiting hole is formed on the outer surface of the limiting plate. A set of fixing plates is fixedly connected to both the upper and lower surfaces of the limiting shell. A fixing hole is formed on the outer surface of the fixing plate. A limiting pin is threadedly connected to the inner ring of the two fixing holes and the inner ring of the limiting hole. The front of the socket is inserted into the back of the plug body.

[0006] In a further embodiment, pressing blocks are fixedly connected to both the left and right sides of the plug body, and the end of the spring away from the groove is fixedly connected to the outer surface of the elastic plate.

[0007] In a further embodiment, a protective sleeve is fixedly connected to the outer surface of the plug body, and the outer surface of the protective sleeve is provided with protective grooves arranged at equal intervals.

[0008] In a further embodiment, the side of the limiting plate away from the through groove is fixedly connected to the outer surface of the elastic plate, and the outer surface of the limiting pin is provided with anti-slip texture.

[0009] In a further embodiment, anti-slip plates are fixedly embedded on both the upper and bottom surfaces of the plug body, and anti-slip protrusions arranged at equal intervals are fixedly connected to the outer surface of the anti-slip plates.

[0010] In a further embodiment, two limiting grooves are formed inside the groove, and the inner walls of the two limiting grooves are slidably connected to limiting rods. The sides of the two limiting rods that are far apart from each other are fixedly connected to the outer surface of each elastic plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: This device, through the design of grooves, elastic plates, springs, through slots, limiting plates, limiting holes, fixing plates, fixing holes, and limiting pins, forms a locking mechanism for the plug body. This increases the stability of the plug body when it is inserted into the socket, preventing the plug body from being easily affected by external forces, thus avoiding loosening, sliding, and falling off. This ensures the stability of the electrical equipment during use and prevents short circuits caused by powering on the equipment after a power outage, thereby protecting the safety of the electrical equipment itself.

[0019] 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.

[0020] Please see Figure 1-4In this utility model, a plug with a locking mechanism includes a socket 1. A limiting shell 2 is fixedly connected to the front of the socket 1. A plug body 3 is provided inside the limiting shell 2. A groove 4 is formed on both the upper and lower surfaces of the plug body 3. An elastic plate 5 is fixedly connected inside the groove 4. A spring 6 is fixedly connected inside the groove 4. A through groove 7 is formed on both the upper and lower surfaces of the limiting shell 2. A limiting plate 8 is provided inside the through groove 7. A limiting hole 9 is formed on the outer surface of the limiting plate 8. A set of fixing plates 10 is fixedly connected to both the upper and lower surfaces of the limiting shell 2. A fixing hole 11 is formed on the outer surface of the fixing plate 10. Two fixing plates 10 are fixedly connected to the upper and lower surfaces of the limiting shell 2. The inner ring of hole 11 and the inner ring of limiting hole 9 are connected by a limiting pin 12 through a common thread. The front of socket 1 is inserted into the back of plug body 3. The locking mechanism of plug body 3 can be formed by the groove 4, elastic plate 5, spring 6, through groove 7, limiting plate 8, limiting hole 9, fixing plate 10, fixing hole 11 and limiting pin 12, which increases the stability of plug body 3 when it is inserted into socket 1, and avoids the plug body 3 from being easily affected by external forces, so as to prevent it from becoming loose, sliding and falling off. This ensures the stability of electrical equipment during use, avoids the situation of short circuit after power is turned on after power failure, and ensures the safety of electrical equipment itself.

[0021] Pressing blocks 13 are fixedly connected to both the left and right sides of the plug body 3. The end of the spring 6 away from the groove 4 is fixedly connected to the outer surface of the elastic plate 5. A protective sleeve 14 is fixedly connected to the outer surface of the plug body 3. The outer surface of the protective sleeve 14 is provided with protective grooves 15 arranged at equal intervals. The protective sleeve 14 and the protective grooves 15 can increase the durability between the plug body 3 and the power cord.

[0022] The side of the limiting plate 8 away from the through groove 7 is fixedly connected to the outer surface of the elastic plate 5. The outer surface of the limiting pin 12 is provided with anti-slip texture 18. The upper surface and the bottom surface of the plug body 3 are both fixedly inlaid with anti-slip plates 16. The outer surface of the anti-slip plates 16 is fixedly connected with anti-slip protrusions 17 arranged at equal intervals. The inside of the groove 4 is provided with two limiting grooves 19. The inner walls of the two limiting grooves 19 are slidably connected to limiting rods 20. The sides of the two limiting rods 20 that are away from each other are fixedly connected to the outer surface of each elastic plate 5. The anti-slip texture 18 increases the friction between the user's fingers and the limiting pin 12. The anti-slip plates 16 and the anti-slip protrusions 17 increase the friction when the user contacts the plug body 3 when unplugging it. The limiting grooves 19 and the limiting rods 20 prevent the elastic plate 5 from being excessively bent due to external forces, thus preventing the elastic plate 5 from breaking.

[0023] The working principle of this utility model is as follows: In use, first pick up the plug body 3 and insert it into the limiting shell 2. When the plug body 3 is fully inserted into the limiting shell 2, it will connect with the socket 1. During insertion, the limiting plate 8, due to its arc shape, will be squeezed by the limiting shell 2, causing the elastic plate 5 to bend and extend into the groove 4. At the same time, the elastic plate 5 will compress the spring 6 and drive the limiting plate 8 into the groove 4. After the plug body 3 is fully inserted into the socket 1, the limiting plate 8 will align with the through groove 7. Then the limiting plate 8 will no longer be squeezed, allowing the spring 6 and the elastic plate 5 to return to their original positions, and driving the limiting plate 8 through the through groove 7. After the limiting plate 8 passes through the through groove 7, the fixing hole 11 will automatically align with the limiting hole 9. Finally, turn the limiting pin 12 into the fixing hole 11 and the limiting hole 9 in sequence to complete the locking and limiting. To pull it out, simply reverse the operation.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0025] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
