The wire passes through the storage bin 5001 and the wire outlet 5002 into the winding drum 2, then passes through the rotating shaft 6 and out of the winding drum 2 from the inside of the rotating shaft 6, and then is connected with the socket body 1. The protective shell 3 is provided with the sealing ring 4 which is made of elastic material. The sealing ring 4 is provided with the pull rope one 103. The pull rope one 103 is provided with the tightener one 104.

[0020] It also includes a ring-shaped waterproof film 102, a pull rope two 105, and a tightener two 106. The conical cover 5 is provided with the ring-shaped waterproof film 102 which is far away from the winding drum 2, and the ring-shaped waterproof film 102 is made of elastic material. The conical cover 5 is provided with a storage bin 5001. The ring-shaped waterproof film 102 is provided with a communication port 10201. The communication port 10201 communicates with the storage bin 5001. The ring-shaped waterproof film 102 is provided with the pull rope two 105. The pull rope two 105 is provided with the tightener two 106.

[0021] The handle is arranged on the conical cover 5, so as to facilitate workers to roll up the electric wire.

[0022] The sealing strip is arranged between the protective shell 3 and the winding drum 2, so as to avoid water flow from entering between the winding drum 2 and the protective shell 3.

[0023] The spring beads 101 are further included; a plurality of spring beads 101 are arranged at both ends of the winding drum 2, and the protective shell 3 is arranged with the clamping grooves corresponding to the spring beads 101 close to the conical cover 5.

[0024] The hydrophobic coating is sprayed on the winding drum 2, the protective shell 3, the sealing ring 4 and the conical cover 5, so as to prolong the service life of the equipment.

[0025] The electric wire outlet 5002 is arranged on the conical cover 5; the ceramic wire ring is arranged on the electric wire outlet 5002, so as to reduce the friction between the electric wire and the electric wire outlet 5002 and facilitate smooth movement of the electric wire.

[0026] The protective shell 3 is made of transparent material, so as to facilitate workers to observe the state of the socket.

[0027] The sealing ring is arranged between the conical cover 5 and the winding drum 2, so as to avoid water flow from entering the cavity 2002.

[0028] The anti-skid texture is arranged on the protective shell 3, so as to facilitate the protective shell 3 to drive the winding drum 2 and the rotating shaft 6 to rotate.

[0029] The working process of the safety type electrical socket convenient to plug and unplug is as follows: When the socket is installed, the cable enters from the communication port 10201, passes through the storage bin 5001 and the electric wire outlet 5002, and then enters the cavity 2002; then the electric wire passes through the rotating shaft 6, extends out of the rotating shaft 6, and passes through the winding drum 2; the worker connects the electric wire and the socket body 1, and then fixes the socket body 1 on the winding drum 2 by screws, so as to be in the state as shown in the Figure 1

[0030] When the socket is used, the user holds the handle on the conical cover 5 with one hand, and pulls the electric wire plug with the other hand; the electric wire is pulled out of the winding drum 2, the plug is connected to the power supply, and then the plug of the electric appliance is inserted into the socket body 1.

[0031] ​In the case of rain outside, the rain falling on the wire will flow along the wire to the socket body 1 at the socket, there is a risk of electric shock. Therefore, after the plug of the electrical appliance is inserted into the socket body 1, the user holds the conical shell 5 with one hand and holds the protective shell 3 with the other hand, pulls the protective shell 3 to the left, drives the sealing ring 4 away from the socket body 1 through the protective shell 3, and the protective shell 3 slides along the sliding groove 2001. When the clamping groove on the right side of the protective shell 3 is buckled with the spring ball 101 on the left side of the winding drum 2, stop pulling the protective shell 3, fix the protective shell 3 through the spring ball 101, avoid the protective shell 3 from sliding, then the user holds the pull rope one 103 with one hand and controls the tightener one 104 to tighten the pull rope one 103 with the other hand. Through the pull rope one 103, the opening of the sealing ring 4 is tightened, so that the splashing water droplets cannot splash on the socket body 1 from the opening of the protective shell 3, and the electric shock phenomenon occurs.

[0032] It should be noted that since the protective shell 3 drives the sealing ring 4 away from the socket on the socket body 1, the distance between the opening of the protective shell 3 and the socket body 1 is extended, and when the plugs of multiple electrical appliances are connected to the socket body 1, the sealing ring 4 cannot be completely closed. By extending the distance between the opening of the protective shell 3 and the socket body 1, the water droplets splashing from the sealing ring 4 that is not completely closed cannot directly contact the socket after entering the inside of the protective shell 3, resulting in electric shock, further improving the safety of electricity.

[0033] Further, in order to prevent the water and impurities adhering to the wire from being wound into the winding drum 2 when the wire used outdoors is wound into the winding drum 2, causing the wire to be in a humid environment for a long time, the present application designs an annular waterproof film 102. In use, the user holds the upper side of the pull rope two 105 with one hand and controls the tightener two 106 with the other hand, pulls the tightener two 106 to tighten the pull rope two 105, and tightens the communication port 10201 of the annular waterproof film 102 through the pull rope two 105, so that the communication port 10201 on the annular waterproof film 102 is attached to the wire. When the user winds the wire, the impurities and water droplets on the wire are scraped off by the annular waterproof film 102, avoiding the wire wound into the winding drum 2 from being in a humid state for a long time, and simultaneously tightening the annular waterproof film 102 during the use of the wire can avoid water flowing along the wire into the cavity 2002.

[0034] Furthermore, to prevent the plug of the socket body 1 from being exposed on the outside during storage or transportation, which could lead to the plug being hooked by other objects, or the plug being thrown off when the user holds the handle on the conical cover 5 due to the rotatable connection between the winding drum 2 and the conical cover 5, this invention designs the conical cover 5 as a hollow structure. When the socket is not in use, the user pulls the tightening device 2 106 away from the annular waterproof membrane 102, releasing the restriction on the connecting port 10201. The worker then inserts the plug of the socket body 1 into the storage compartment 5001 and tightens the connecting port 10201, preventing the plug from being thrown off during the transportation of the socket body 1 and causing the wiring to become loose.

[0035] After using this invention, when rewinding the wire, the user first pulls the tensioner 104 away from the sealing ring 4 to release the restriction on the sealing ring 4. Then, the user holds the handle on the conical cover 5 with one hand and the protective shell 3 with the other hand, pushing the protective shell 3 from left to right, causing the protective shell 3 to slide to the right along the slide groove 2001, so that the protective shell 3 returns to its original position. Figure 1 As shown in the diagram, insert the socket body 1 into the storage compartment 5001.

[0036] It should be noted that the wire outlet 5002 of the present invention is higher than the rotating shaft 6, so that the wire is inclined between the rotating shaft 6 and the wire outlet 5002, which makes it easier for the wire to be wound on the rotating shaft 6.

[0037] Based on the above workflow, we can see that the present invention has the following effects: When using the socket in rainy weather, as the user pulls the protective shell 3 away from the socket body 1, the protective shell 3 moves the sealing ring 4 away from the socket body 1. The sealing ring 4 then expands and seals the opening of the protective shell 3, preventing rainwater from flowing along the wires and dripping onto the socket body 1. Furthermore, because the wires pass through the middle of the sealing ring 4, when multiple appliances are connected to the socket body 1, the sealing ring 4 may not completely seal after tightening, leaving gaps. This can allow splashing rainwater to seep in through the gaps between the sealing ring 4 and the wires. However, because the protective shell 3 moves the sealing ring 4 away from the socket body 1, increasing the distance between the opening of the protective shell 3 and the socket body 1, it prevents water droplets splashing from the partially sealed sealing ring 4 from entering the protective shell 3 and failing to directly contact the socket, thus preventing leakage and further improving electrical safety.

[0038] The conical cover 5 designed in this invention has a hollow structure. When the socket body 1 is not in use, the plug of the socket body 1 can be inserted into the storage compartment 5001, which can prevent the plug from being thrown out when the user moves the socket body 1, resulting in loose wiring.

[0039] Additional technical effects of the present application are as follows: Wherein, as shown in Figure 2 The sealing ring is arranged on the contact side of the protective shell 3 and the winding drum 2, and can scrape off water droplets on the outer side of the winding drum 2 during the movement of the protective shell 3 from left to right by the user.

[0040] Wherein, as shown in Figure 6 The pulling rope two 105 and the tightener two 106 arranged on the annular waterproof film 102 can change the caliber of the communication port 10201, so as to facilitate the replacement of the electric wire.

[0041] The above is only an embodiment of the present application and is not intended to limit the present application. Any equivalent replacement within the principles of the present application shall be included in the protection scope of the present application. The contents of the present application not described in detail belong to the prior art known to those skilled in the art.
