Technical Field

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

[0002] A power plug is a component that connects electrical equipment to a power outlet. Its main function is to provide a current path so that the equipment can obtain the required current. Power plugs come in various types and specifications.

[0003] Three-prong plugs are used in the connection of some devices, such as computers and refrigerators. When in use, the plug is inserted into the recessed socket of the device, so that the slot of the three-prong plug connects with the pins in the socket to achieve normal current flow. However, in actual use, it has been found that some three-prong plugs have poor connection with the socket and lack corresponding reinforcement parts. As a result, when the power cord is pulled, the plug may become loose and detach, causing a short circuit in the device and affecting normal use. Utility Model Content

[0004] The technical problem this utility model aims to solve is that some three-prong plugs have poor connection with the socket and lack corresponding reinforcing components, which can cause the plug to loosen and detach when the power cord is pulled, leading to a short circuit in the device and affecting normal use.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a power plug with a self-locking structure, including an exposed section and an embedded section. The surface of the exposed section is fixedly connected with a soft sheath, and the surface of the embedded section is provided with a self-locking device, wherein the self-locking device limits and fixes the plug in the plugged state by means of a fixing plate and a fixing block.

[0006] The effect achieved by the above components is that when the plug is inserted into the device socket, the inner end of the plug is first inserted into the socket, and then the inner end is operated to the side closer to the outside of the device to make the connection position of the plug more secure and stable.

[0007] Preferably, the self-locking device includes a rotating shaft installed in the groove of the inner wall of the embedded section, wherein a fixing plate is rotatably disposed on the arc surface of the rotating shaft, wherein a plurality of evenly distributed protrusions are provided on one side surface of the fixing plate, and a fixing groove is provided on the surface of the fixing plate, wherein a pressure plate is installed on the surface of the fixing plate, and fixing blocks are slidably disposed on both sides of the surface of the embedded section located on the fixing plate, wherein a spring is installed on one side surface of the fixing plate, and the other end of the spring is fixedly connected to the inner wall of the embedded section.

[0008] The effect achieved by the above components is that the power plug can be more stably inserted into the socket during use, and is less likely to loosen or come off due to factors such as pulling or tugging on the power cord during use, thus ensuring stable connection and use of the equipment and improving the performance of the plug.

[0009] Preferably, the self-locking device further includes a lever mounted on the surface of the fixed block, wherein the lever assists in the sliding displacement of the fixed block.

[0010] The effect achieved by the above components is that, by setting the toggle, the fixing block can be quickly slid by toggling the toggle when the plug is disassembled, thereby quickly separating the fixing block from the fixing plate, making the use of the plug more convenient.

[0011] Preferably, the self-locking device further includes a semi-circular block installed on one side of the fixing plate, and one side surface of the fixing block is inclined.

[0012] The effect achieved by the aforementioned component is that, by setting the semicircular block and the inclined surface of the fixed block, when the fixed plate rotates to the self-locking position, the fixed blocks on both sides can be squeezed apart by the contact and pressure of the semicircular block and the inclined surface, thereby improving the ease of use of the self-locking device.

[0013] Preferably, sliders are fixedly connected to both sides of the surface of the fixed block, and the sliders are slidably disposed with respect to the inner wall of the embedded section.

[0014] The effect achieved by the above components is that, by setting the slider, the fixed block can slide more stably during use and is less prone to shaking, thereby making the self-locking position of the fixed plate more stable and limited.

[0015] Preferably, a protective device is provided on the surface of the exposed section at the position of the soft sheath. The protective device includes two protective shells, which cover the surface of the soft sheath and are respectively connected and fixed to the exposed section by means of screws.

[0016] The effect achieved by the above components is that when the power cord is pulled or swayed during the use of the plug, the soft sheath is less likely to swing excessively, thus making the connection between the soft sheath and the exposed section less likely to break or be damaged, and can better and more durablely protect the power cord.

[0017] Preferably, the protective device further includes a protective pad installed on the inner wall of the protective shell, wherein the protective pad enhances the protective effect of the protective shell.

[0018] The effect achieved by the above components is that by adding a protective pad, the protective shell can increase the friction while protecting and covering the soft sheath, and at the same time make the covering more snug, so that the soft sheath is less likely to shake and break when the plug is in use.

[0019] Preferably, the protective device further includes a washer mounted on the arc surface of the screw, the washer assisting in the stable installation of the screw.

[0020] The effect achieved by the above components is that, through the setting of the shims, the screws can fit more securely and stably with the protective shell during installation and use, making it less likely for gaps to form. This makes the position of the protective shell more stable and better prevents the soft sheath from breaking or being damaged.

[0021] The beneficial effects of this utility model are:

[0022] The power plug of this utility model can be more stably inserted into the socket during use, and is less likely to loosen or detach due to pulling or tugging of the power cord during use, thus ensuring stable connection and use of the device and improving the plug's performance.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1 and Figure 2 The power plug shown has a self-locking structure, including an exposed section 1 and an embedded section 2. A soft sheath 3 is fixedly connected to the surface of the exposed section 1, and a self-locking device 4 is provided on the surface of the embedded section 2. The self-locking device 4 limits and fixes the plug in the plugged state by means of a fixing plate 42 and a fixing block 44. A protective device 5 is provided on the surface of the exposed section 1 at the position of the soft sheath 3.

[0032] Figure 1 , Figure 2 and Figure 3 The self-locking device 4 shown includes a rotating shaft 41 installed in a groove in the inner wall of the embedded section 2. A fixing plate 42 is rotatably mounted on the arc surface of the rotating shaft 41. One side surface of the fixing plate 42 has several evenly distributed protrusions, and the surface of the fixing plate 42 has a fixing groove 43. A pressure plate 48 is mounted on the surface of the fixing plate 42. Fixing blocks 44 are slidably mounted on both sides of the surface of the embedded section 2 on the fixing plate 42. A spring 45 is mounted on one side surface of the fixing plate 42, and the other end of the spring 45 is fixedly connected to the inner wall of the embedded section 2. When the plug is inserted into the device socket, the embedded end of the plug is first inserted into the socket, and a section of the embedded end is exposed near the outer surface of the device. Then, move the two fixing blocks 44 on both sides to separate them. Then press the pressure plate 48 on the fixing plate 42 to make the fixing plate 42 rotate around the pivot 41 until the protrusion on one side of the fixing plate 42 contacts and presses against the inner wall of the socket. Then release the fixing block 44, and the fixing block 44 will slide under the elastic force of the spring 45 until the fixing block 44 is inserted into the fixing groove 43 on the surface of the fixing plate 42, so that the position of the fixing plate 42 is fixed. At this time, when the power plug is used, it can be more stably plugged into the socket. It is not easy for the plug to loosen and come off due to the pulling of the power cord during use, which ensures the stable connection and use of the equipment and improves the use effect of the plug.

[0033] Figure 1 , Figure 2 and Figure 3The self-locking device 4 shown also includes a toggle block 46 mounted on the surface of the fixed block 44. The toggle block 46 assists in the sliding displacement of the fixed block 44. By setting the toggle block 46, the fixed block 44 can be quickly slid by toggling the toggle block 46 when the plug is disassembled, thereby quickly separating the fixed block 44 from the fixed plate 42, making the use of the plug more convenient. The self-locking device 4 also includes a semi-circular block 49 mounted on one side of the fixed plate 42, and one side surface of the fixed block 44 is inclined. By setting the semi-circular block 49 and the inclined surface of the fixed block 44, when the fixed plate 42 is rotated to the self-locking position, the contact and pressure between the semi-circular block 49 and the inclined surface can push the fixed blocks 44 on both sides apart, improving the ease of use of the self-locking device 4. Slider blocks 47 are fixedly connected to both sides of the surface of the fixed block 44, and the slider blocks 47 are slidably set with the inner wall of the embedded section 2. By setting the slider blocks 47, the fixed block 44 can slide more stably during use and is less prone to shaking, thereby more stably limiting the self-locking position of the fixed plate 42.

[0034] Figure 1 and Figure 4 The protective device 5 shown includes two protective shells 51, which cover the surface of the soft sheath 3. The two protective shells 51 are respectively connected and fixed to the exposed section 1 by means of screws 52. When the plug is in use, the position of the soft sheath 3 is protected. First, the two protective shells 51 are covered on the arc surface of the soft sheath 3. Then, the screws 52 are inserted through the surface of the protective shells 51, so that the screws 52 are threadedly connected to the surface of the exposed section 1, thereby fixing the position of the protective shells 51. At this time, when the power cord is pulled and swayed during the use of the plug, the soft sheath 3 is not prone to excessive swaying, so that the connection position between the soft sheath 3 and the exposed section 1 is not prone to breakage or damage, and can better and more durablely protect the power cord.

[0035] Figure 1 and Figure 4 The protective device 5 shown also includes a protective pad 54 installed on the inner wall of the protective shell 51. The protective pad 54 enhances the protective effect of the protective shell 51. By setting the protective pad 54, the protective shell 51 can increase the friction when protecting and covering the soft sheath 3, and also make the covering more snug. This makes the soft sheath 3 less likely to shake and break when the plug is in use. The protective device 5 also includes a washer 53 installed on the arc surface of the screw 52. The washer 53 assists in the stable installation and use of the screw 52. By setting the washer 53, the screw 52 can fit more securely and stably with the protective shell 51 during installation and use, and there is less chance of gaps. This makes the position of the protective shell 51 more stable and better prevents the soft sheath 3 from breaking and being damaged.

[0036] Working principle: When the plug is inserted into the device socket, first insert the inner end of the plug into the socket, with a portion of the inner end protruding from the outer surface of the device. Then press the pressure plate 48 on the fixing plate 42, causing the fixing plate 42 to rotate around the pivot 41. During the pressing process, the semi-circular block 49 fixedly connected to the fixing plate 42 will contact and squeeze the inclined surface of the fixing block 44, separating the two fixing blocks 44 until the protrusion on one side of the fixing plate 42 contacts and squeezes the inner wall of the socket, increasing the contact friction and squeezing force between the inner section 2 and the inner wall of the socket. Then, the fixing block 44 will slide under the elastic force of the spring 45 until the fixing block 44 is inserted into the fixing groove 43 on the surface of the fixing plate 42, fixing the position of the fixing plate 42. At this time, the power plug can be more stably plugged into the socket during use, and it is not easy for the plug to loosen or detach due to factors such as pulling or tugging of the power cord during use, ensuring stable connection and use of the device and improving the performance of the plug.

[0037] When the plug is in use, the position of the soft sheath 3 is protected. First, two protective shells 51 are wrapped around the arc surface of the soft sheath 3. Then, screws 52 are inserted through the surface of the protective shells 51, so that the screws 52 are threadedly connected to the surface of the exposed section 1, thereby fixing the position of the protective shells 51. At this time, when the power cord is pulled and swayed during the use of the plug, the soft sheath 3 is not prone to excessive swaying, so that the connection position between the soft sheath 3 and the exposed section 1 is not prone to breakage or damage, and can better and more durablely protect the power cord.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
