Description

Technical Field

[0001] This utility model relates to the field of adapter plug technology, specifically a safety adapter plug that prevents detachment. Background Technology

[0002] The main function of a power adapter is to convert and transmit electricity. It allows different plugs or power adapters to be easily plugged into different power outlets or devices. This conversion involves not only physical connections but also compatibility with electrical standards. With a power adapter, electrical appliances can receive a stable and safe power supply in different countries or regions.

[0003] When using existing adapter plugs, the connection between the adapter plugs is only through the plug and the slot, which results in poor stability of the connection between the adapter plugs. As a result, they may separate due to pulling, thus leading to poor stability.

[0004] To address the aforementioned deficiencies, the anti-disconnect socket and anti-disconnect adapter with publication number CN201340929Y utilize a retaining ring within the socket. The serrated edge of the central through hole of the retaining ring is subjected to the expansion force of the plug pins inserted into the hole, thus ensuring a secure connection, guaranteeing the normal use of electrical appliances, and eliminating safety hazards.

[0005] In actual use of the above-mentioned device, although the connection stability is improved by the retaining ring, after connection, the adapter plug may be suddenly subjected to force due to strong movement, which may cause the adapter plug to separate from the anti-disconnect socket, resulting in poor stability.

[0006] Therefore, we proposed a safety adapter plug that prevents it from falling off, which can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a safety adapter plug that prevents it from falling off, in order to solve the problem mentioned in the background art that the adapter plug may be suddenly subjected to force due to vigorous movement, which may cause the adapter plug to separate from the anti-dislodgement socket, resulting in poor stability.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a safety adapter plug that prevents detachment, comprising a plug body, wherein the left end of the plug body is inserted into the right side of the adapter body, and an anti-slip block is provided on the left end of the adapter body;

[0009] The plug body has a locking block that slides inside, and the left end of the locking block is triangular in shape. The left end of the locking block extends into the slot to form a locking mechanism. The slot is located inside the converter body, and the inner end of the locking block is connected to a first spring, and the inner end of the first spring is connected to the inside of the plug body.

[0010] Preferably, the converter body has a sensing pin inside, and the right end of the sensing pin extends into the interior of the connecting groove, which is opened inside the plug body.

[0011] Preferably, a push block is slidably connected inside the converter body, and the left end of the push block extends into the interior of the gas storage rod to form a sliding mechanism, and the gas storage rod is nested inside the converter body.

[0012] Preferably, a rubber pad is fixed to the left end of the push block, and the outer wall of the rubber pad fits into the inner wall of the gas storage rod to form a sealing mechanism.

[0013] Preferably, the inner end of the gas storage rod is connected to a gas pipe, and the gas pipe is nested inside the converter body.

[0014] Preferably, the inner end of the trachea is connected to the airbag, and the outer wall of the airbag is fixed to the inner wall of the converter body, and the airbag and the outer wall of the plug body fit together to form a sealing mechanism.

[0015] Preferably, a second spring is internally connected to the gas storage rod, and the right end of the second spring is attached to the left side of the rubber pad.

[0016] Compared with the prior art, the beneficial effects of this utility model are: the anti-detachment safety adapter plug has high stability and high security. The use of a locking block allows the adapter body and the plug body to engage, thereby improving connection stability and preventing detachment. Furthermore, the use of a sensing pin allows the sensing pin to detect temperature, thus improving safety during use. The specific details are as follows:

[0017] (1) A locking block is provided. Through the engagement between the locking block and the slot, a stable connection can be made between the converter body and the plug body, thereby preventing the converter body and the plug body from separating due to sudden force, thus achieving the purpose of preventing detachment.

[0018] (2) It is equipped with a sensing pin, which can sense the temperature inside the plug body. When the sensing pin gets too hot, it will disconnect the power supply of the converter body, thereby achieving the purpose of preventing high temperature and improving the safety of use.

[0019] (3) A push block is provided. The push block is slidably connected to the inside of the converter body. The left end of the push block extends into the inside of the gas storage rod to form a sliding mechanism. The gas storage rod is nested inside the converter body. Then, the gas in the gas storage rod can be squeezed by the movement of the push block, which facilitates the delivery of gas in the gas storage rod.

[0020] (4) A second spring is provided. The second spring is connected to the inside of the gas storage rod, and the right end of the second spring is attached to the left side of the rubber pad. The second spring can facilitate the reset of the push block, thereby facilitating the re-transmission of gas into the gas storage rod for storage.

[0021] (5) A rubber pad is provided. The rubber pad is fixed to the left end of the push block, and the outer wall of the rubber pad fits into the inner wall of the gas storage rod to form a sealing mechanism.

[0030] 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.

[0031] Example 1: A safety adapter plug designed to prevent detachment solves the problem that existing adapter plugs may suddenly be subjected to force due to vigorous movement, leading to separation between the adapter plug and the anti-detachment socket, resulting in poor stability. The use of locking block 4 improves the stability of the connection between the plug body 1 and the adapter body 2. The following is disclosed:

[0032] The left end of the plug body 1 is inserted into the right side of the converter body 2, and the left end of the converter body 2 is provided with an anti-sliding block 3; the plug body 1 is slidably connected with a locking block 4, and the left end of the locking block 4 is triangular in shape, and the left end of the locking block 4 extends into the inside of the slot 5 to form a locking mechanism. The slot 5 is opened inside the converter body 2, and the inner end of the locking block 4 is connected to a first spring 6, and the inner end of the first spring 6 is connected to the inside of the plug body 1.

[0033] refer to Figures 1 to 5 Insert the plug body 1 into the adapter body 2, and then insert the adapter body 2 into the socket to achieve the conversion purpose. The movement of the plug body 1 will cause the locking block 4 to squeeze the adapter body 2, thereby causing the locking block 4 to slide inward into the plug body 1. The movement of the locking block 4 will squeeze the first spring 6, thereby compressing the first spring 6. After the adapter body 2 and the plug body 1 are connected, the force of the first spring 6 will push the locking block 4 into the slot 5 to form a lock, thereby enabling a stable connection between the plug body 1 and the adapter body 2, thereby achieving the purpose of preventing detachment. By reversing the above operation, the plug body 1 and the adapter body 2 can be separated.

[0034] Example 2: A safety adapter plug designed to prevent detachment solves the problem of high temperatures generated during prolonged use, which leads to poor safety. The safety is improved by using the sensing pin 7. The following is disclosed:

[0035] The converter body 2 has a sensing pin 7 inside, and the right end of the sensing pin 7 extends into the interior of the connecting groove 8, and the connecting groove 8 is opened inside the plug body 1.

[0036] refer to Figure 4 and Figure 5When the plug body 1 is connected to the converter body 2, the sensing pin 7 is inserted into the interior of the sensing pin 7, which monitors the temperature inside the plug body 1 in real time. When the sensing pin 7 senses that the temperature is too high, it will cut off the power to the converter body 2, thereby suspending the use of the converter body 2 and cutting off the power to the plug body 1. This avoids the danger caused by the high temperature of the plug body 1 and improves the safety of use.

[0037] Example 3: A safety adapter plug designed to prevent detachment solves the problem that water stains may enter the connection between the adapter body 2 and the plug body 1, causing damage. The use of an airbag 13 improves the seal, thus preventing water stains from entering. The following is disclosed:

[0038] The converter body 2 is internally connected to a push block 9, and the left end of the push block 9 extends into the interior of the air storage rod 11 to form a sliding mechanism. The air storage rod 11 is nested inside the converter body 2. The left end of the push block 9 is fixed with a rubber pad 10, and the outer wall of the rubber pad 10 fits into the inner wall of the air storage rod 11 to form a sealing mechanism. The inner end of the air storage rod 11 is connected to an air tube 12, and the air tube 12 is nested inside the converter body 2. The inner end of the air tube 12 is connected to an air bladder 13, and the outer wall of the air bladder 13 is fixed to the inner wall of the converter body 2. The air bladder 13 fits into the outer wall of the plug body 1 to form a sealing mechanism. The interior of the air storage rod 11 is connected to a second spring 14, and the right end of the second spring 14 fits into the left side of the rubber pad 10.

[0039] refer to Figure 4 , Figure 6 and Figure 7 When the converter body 2 is connected to the plug body 1, the plug body 1 will squeeze the push block 9, which will then move the push block 9 into the air reservoir 11. The push block 9 will then deliver the gas in the air reservoir 11 to the air tube 12 through the rubber pad 10. The gas will then be delivered to the airbag 13 through the air tube 12. The airbag 13 will then seal the gap between the plug body 1 and the converter body 2. The movement of the rubber pad 10 will squeeze the second spring 14, which will be compressed to prevent water from entering between the plug body 1 and the converter body 2, thus achieving waterproofing. After the plug body 1 and the converter body 2 are separated, the push block 9 will be reset by the force of the second spring 14, which will create a negative pressure inside the air reservoir 11. The negative pressure will then deliver the gas in the airbag 13 back into the air reservoir 11 for storage, which will allow the airbag 13 to contract, thereby avoiding friction between the airbag 13 and the plug body 1 and improving the service life of the airbag 13.

[0040] Working principle: When using this type of anti-drop safety adapter plug, first, refer to... Figures 1 to 5 Insert the plug body 1 into the converter body 2, and then insert the converter body 2 into the socket to achieve the conversion purpose. The movement of the plug body 1 will cause the locking block 4 to squeeze the converter body 2. After the converter body 2 and the plug body 1 are connected, the force of the first spring 6 pushes the locking block 4 into the slot 5 to form a lock, thereby making the plug body 1 and the converter body 2 stably connected, thus achieving the purpose of preventing it from falling off. And by reversing the above operation, the plug body 1 and the converter body 2 can be separated.

[0041] refer to Figure 4 and Figure 5 When the plug body 1 is connected to the converter body 2, the sensing pin 7 is inserted into the inside of the sensing pin 7, so that the sensing pin 7 can monitor the temperature inside the plug body 1 in real time. When the sensing pin 7 senses that the temperature is too high, it will stop the use of the converter body 2, thereby avoiding the danger caused by the high temperature of the plug body 1 and improving the safety of use.

[0042] refer to Figure 4 , Figure 6 and Figure 7 When the converter body 2 is connected to the plug body 1, the plug body 1 will squeeze the push block 9, which will then be squeezed and move into the air storage rod 11. Then, the gas is delivered to the airbag 13 through the air tube 12, which will seal the gap between the plug body 1 and the converter body 2, thus preventing water from entering between the plug body 1 and the converter body 2. After the plug body 1 and the converter body 2 are separated, the push block 9 is reset by the force of the second spring 14, and then the gas in the airbag 13 is delivered back to the air storage rod 11 through negative pressure, which will cause the airbag 13 to contract, thereby avoiding friction between the airbag 13 and the plug body 1 and thus improving the service life of the airbag 13.
