DETAILED DESCRIPTION
[0029] The following is combined with Figure 1-5 This application is described in further detail.
[0030] Embodiment 1: The present application embodiment discloses a waterproof socket, such as Figure 1 and 2 As shown, it includes a socket base 1 and a waterproof cover 2. The socket base 1 is fixedly mounted on the wall, and a socket for inserting a plug of a power supply is provided on the socket base 1. The waterproof cover 2 and the socket base 1 are hinged, and the hinge axis of the two is located above the socket base 1 and the axial direction is horizontal. The lower edge of the waterproof cover 2 and the socket are fixedly provided with mutually matching clamping structures. When the waterproof cover 2 is naturally turned down, the two are mutually clamped, and the socket on the socket base 1 is closed.
[0031] like Figure 1 , 2As shown in Figure 3, there are two groups of three-pin sockets, and the two groups of sockets are arranged horizontally. The sockets for the live wire and the neutral wire are located below the ground wire, that is, the socket base 1 can accommodate up to two triangular plugs to be inserted at the same time. A matching hole 3 is formed between the waterproof cover 2 and the socket base 1: a semicircular groove 31 is provided on both the socket base 1 and the waterproof cover 2. When the waterproof cover 2 is turned down to close the socket base 1, the semicircular groove 31 of the socket base 1 and the semicircular groove 31 of the waterproof cover 2 are connected to form a matching hole 3, and the power supply wire 41 passes through the matching hole 3, so that the plug of the electrical appliance can still be inserted into the socket when the waterproof cover 2 closes the socket base 1. A sealing member 32 is provided on the hole wall of the matching hole 3, and the sealing member 32 abuts against the side wall of the electric wire 41; the sealing member 32 includes a rubber strip 321, and the rubber strip 321 is fixedly connected to the groove wall of the semicircular groove 31. When the electric wire 41 passes through the matching hole 3, the rubber strip 321 abuts against the side wall of the electric wire 41 tightly, thereby improving the sealing performance of the matching hole 3.
[0032] like Figure 1 and 2 As shown, the sealing member 32 also includes an auxiliary plate 322, an auxiliary spring 323 is provided in the socket base 1, one end of the auxiliary spring 323 is fixedly connected to the socket base 1, and the other end is fixedly connected to the auxiliary plate 322, the auxiliary plate 322 is slidably connected to the socket base 1, the sliding direction is perpendicular to the axis of the matching hole 3, and the plate surface of the auxiliary plate 322 is also perpendicular to the axis of the matching hole 3; when the wire 41 of the electrical appliance does not pass through the matching hole 3, the edge of the auxiliary plate 322 abuts against the hole wall of the matching hole 3, and the matching hole 3 is completely closed. When the wire 41 passes through the matching hole 3, the wire 41 generates an abutting force on the auxiliary plate 322, so that the auxiliary plate 322 is retracted into the socket base 1, and does not affect the existence of the wire 41 in the matching hole 3.
[0033] like Figure 1 , 2As shown in FIG. 3 , there are two common connection forms between the three-pin plug 4 and its own wire 41. The first is that the length direction of the wire 41 is perpendicular to the direction of the socket, and the wire 41 is located on the side close to the live and neutral wires of the plug; the second is that the length direction of the wire 41 is consistent with the direction of the socket, and in the projection along the direction of the socket, the wire 41 is located between the live wire end, the neutral wire end and the ground wire end. In this embodiment, the two sets of sockets of the socket base 1 are respectively adapted to two types of three-pin plugs 4. The waterproof cover 2 includes a full cover portion 21 and a half cover portion 22 which are fixedly connected to each other, wherein one group of three-pin sockets corresponds to the full cover portion 21, and the other group of three-pin sockets corresponds to the half cover portion 22. When the waterproof cover 2 closes the socket base 1, the lower edge of the full cover portion 21 is flush with the lower edge of the socket base 1, and the lower edge of the half cover portion 22 is located between the live wire hole and the ground wire hole, that is, the matching hole 3 formed by the full cover portion 21 and the socket base 1 is located at the bottom of the socket base 1, and the hole axis is perpendicular to the direction of the socket, so that the wire 41 of the first type three-pin plug 4 can pass through; the matching hole 3 formed by the half cover portion 22 and the socket base 1 is located in the middle of the height range of the socket base 1, and the hole axis is parallel to the direction of the socket, so that the wire 41 of the second type three-pin plug 4 can be inserted.
[0034] like Figure 3 As shown, a drainage slope 11 is provided inside the socket base 1 and below the socket hole corresponding to the half cover portion 22. The end of the drainage slope 11 close to the full cover portion 21 is inclined downward, and the end of the drainage slope 11 close to the full cover portion 21 is located at the lower edge of the socket base 1; even if there is condensed water or accumulated water in the socket base 1 corresponding to the half cover portion 22, the water can flow downward along the drainage slope 11 and be discharged from the socket base 1.
[0035] Embodiment 2: like Figure 4 As shown, the difference from the first embodiment is that only one set of three-pin sockets is provided on the socket base 1, and there are two matching holes 3, one of which is formed between the waterproof cover 2 and the socket base 1 (when the waterproof cover 2 is buckled), which is consistent with the matching hole 3 on the edge of the full cover 21 of the first embodiment, and the hole axis is in the vertical direction, and the other is opened on the waterproof cover 2, and the hole axis is in the horizontal direction, and the axes of the two matching holes 3 are located on the same vertical plane. A connecting slit 23 is opened on the waterproof cover 2, and the two matching holes 3 are respectively located at the two ends of the connecting slit 23 and are connected to the connecting slit 23. The wire 41 can enter the connecting slit 23 through the semicircular groove 31 on the edge of the waterproof cover 2 and finally enter the matching hole 3 in the middle of the waterproof cover 2. The two three-pin plugs 4 can selectively pass through one of the matching holes 3 according to the situation of their own wires 41.
[0036] like Figure 4 and 5As shown, a blocking piece 24 is movably provided on the waterproof cover 2 and located at the connecting slit 23. When the wire 41 of the electrical appliance does not pass through the connecting slit 23, the blocking piece 24 closes the connecting slit 23. The blocking piece 24 is two movable bars 241, which are hinged to the waterproof cover 2. A single movable bar 241 is located at one side edge of the connecting slit 23, and the hinge axis is consistent with the length direction of the connecting slit 23. The material of the movable bar 241 is a hard rubber strip 321. A torsion spring (not shown in the figure) is provided on the hinge axis of the movable bar 241. In the natural state, the movable bar 241 is at an angle position that closes the connecting slit 23. The waterproof cover 2 is provided with a friction rod 242, and a friction edge 2421 is fixedly connected to the side of the friction rod 242 facing the movable bar 241. The socket base 1 is fixedly connected with a contact block 12. When the waterproof cover 2 and the socket base 1 are clamped with each other, the contact block 12 is located on the side of the friction rod 242 away from the movable bar 241 and abuts against the friction rod 242, so that the friction edge 2421 is deformed close to the movable bar 241, and the friction edge 2421 abuts against the movable bar 241, thereby generating a large static friction force on the movable bar 241, thereby improving the state stability of the movable bar 241, thereby improving the sealing of the connecting seam 23 when the waterproof cover 2 is in the buckled state.
[0037] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
