Specifically, referring to fig. 3 and 4, both sides of the first end of the insulating fixing base 300 are provided with a first rotation shaft 310 and a second rotation shaft 320. In the embodiment of the present utility model, the first rotating shaft 310 and the second rotating shaft 320 are integrated, that is, the first rotating shaft 310 and the second rotating shaft 320 are located on the same rotating shaft, the rotating shaft is arranged on the insulating fixing leg 300 in a penetrating manner, and two ends of the rotating shaft are located at two sides of the first end of the insulating fixing leg 300, so as to form the first rotating shaft 310 and the second rotating shaft 320. In other embodiments, the first shaft 310 and the second shaft 320 may be two independent shafts, and the first shaft 310 and the second shaft 320 are coaxially disposed, but not directly connected. The insulating fixing base 300 is rotatably coupled to the first sidewall 110 of the housing 100 through the first and second rotating shafts 310 and 320. The casing 100 is internally provided with a pressing plate 600, two sides of the pressing plate 600 are provided with a first connecting wall 610 and a second connecting wall perpendicular to the first side wall 110, and one side of the first connecting wall 610 and the second connecting wall, which faces the first side wall 110, is respectively provided with a first U-shaped groove 620 and a second U-shaped groove. The inner side (i.e., the side far from the socket 20) of the first sidewall 110 is provided with a plurality of screw posts 113, the pressing plate 600 is provided with a plurality of through holes 630 corresponding to the screw posts 113, and a plurality of screws 700 are engaged with the screw posts 113 through the through holes 630 to detachably connect the pressing plate 600 to the first sidewall 110. In other embodiments, the platen 600 may be removably attached to the first sidewall 110 by a snap-fit arrangement or other suitable attachment means. After the pressing plate 600 is connected to the first side wall 110, the first connecting wall 610 and the second connecting wall are attached to the first side wall 110 toward one side of the first side wall 110, a first U-shaped hole is formed between the first U-shaped groove 620 and the first side wall 110, a second U-shaped hole is formed between the second U-shaped groove and the first side wall 110, and the first rotating shaft 310 and the second rotating shaft 320 are respectively inserted into the first U-shaped hole and the second U-shaped hole and can rotate in the first U-shaped hole and the second U-shaped hole, so that the first end of the insulating fixing leg 300 is rotatably connected with the first side wall 110. In other embodiments, the first U-shaped groove 620 and the second U-shaped groove may be replaced with a C-shaped groove or other suitable shaped groove, so long as the aperture formed between the groove and the first sidewall 110 is capable of limiting the radial direction of the first shaft 310 and the second shaft 320 and is capable of allowing the first shaft 310 and the second shaft 320 to rotate therein.
In the embodiment of the present utility model, the insulating fixing leg 300 includes two fixing posts 360, and the fixing posts 360 may have the same or similar shape as the pins 200 so as to be inserted into the socket 20. In other embodiments, the number of the fixing posts 360 may be one or three, and those skilled in the art may set the number as desired. When the insulating fixing base 300 is in the unfolded position (see fig. 1), the fixing posts 360 are perpendicular to the first side wall 110 of the housing 100. The relative positions of the securing posts 360 and prongs 200 in the extended position on the first side wall 110 may be determined based on the position of adjacent sockets on the receptacle 20 (i.e., a conventional wall receptacle). When the insulating fixing base 300 is in the extended position and the pins 200 are inserted into the first sockets 21 of the socket 20, the insulating fixing base 300 is inserted into the second sockets 22 of the socket 20, that is, the fixing posts 360 on the insulating fixing base 300 are inserted into the second sockets 22 of the socket 20. The insulating fixing leg 300 may be made of an insulating material, such as hard plastic, rubber, etc., so that the insulating fixing leg 300 only performs a fixing function and prevents the insulating fixing leg from forming an electrical connection with the socket 20. The insulating fixing pins 300 and the pins 200 are plugged into the socket 20 together, so that the contact stability of the plug structure 10 and the socket 20 can be effectively enhanced, and the plug structure 10 is not easy to fall off from the socket 20. When the insulating fixing base 300 is in the retracted position (see fig. 5), the fixing post 360 is received in the housing 100 and does not protrude from the outer surface of the first sidewall 110 (the surface of the first sidewall 110 facing the socket 20), so that when there is only one socket on the socket 20, the insulating fixing base 300 can be rotated to switch to the retracted position so that it does not affect the plugging of the plugging structure 10 to the socket 20 through the pins 200. In the embodiment of the present utility model, the first side wall 110 of the housing 100 is provided with the receiving groove 111, the receiving groove 111 includes an opening on the first side wall 110 and a side wall extending from the edge of the opening to the inside of the housing 100, and the shape of the opening matches the shape of the fixing post 360, so that the receiving groove 111 can receive the insulating fixing leg 300 (i.e. the fixing post 360 on the insulating fixing leg 300) in the retracted position, so that it does not protrude from the outer side surface of the first side wall 110.
The first elastic member is disposed inside the housing 100 and is configured to push the insulating fixing leg 300 to rotate from the retracted position to the extended position by self elastic force. In the embodiment of the utility model, the first elastic member is a torsion spring (i.e. a torsion spring), and when the two ends of the torsion spring rotate around the center of the spring, the spring generates torque or rotational force to push the two ends to return to the initial positions. The two torsion springs are symmetrically sleeved on the first rotating shaft and the second rotating shaft, the two torsion springs are basically identical in arrangement mode, and the arrangement mode is described only by the torsion spring 400 sleeved on the first rotating shaft 310. The first end of the torsion spring 400 abuts against the first sidewall 110, and the second end of the torsion spring 400 abuts against a stop portion 330 provided at the first end of the insulating fixing leg 300, and the stop portion 330 may be a groove wall of a groove provided at the first end of the insulating fixing leg 300 for accommodating the second end of the torsion spring 400. The torsion angle of the torsion spring 400 when the insulation fixing leg 300 is in the retracted position is greater than the torsion angle of the torsion spring 400 when the insulation fixing leg 300 is in the extended position, that is, the deflection angle of both ends of the torsion spring 400 with respect to the initial position thereof. In the embodiment of the present utility model, the torsion spring 400 is not in an initial state (untwisted state) but has been twisted by a certain angle when the insulating fixing base 300 is in the extended position. Therefore, the torsion spring 400 can push the insulation fixing leg 300 to rotate from the retracted position to the extended position under the action of self-elastic force, and the elastic force of the torsion spring 400 can keep the insulation fixing leg 300 stable when in the extended position, and is not easy to incline when being plugged into the second socket 22 of the socket 20. In the embodiment of the utility model, when the insulating fixing leg 300 rotates to the extended position, a limiting surface on the first end of the insulating fixing leg 300 abuts against the side wall of the accommodating groove 111, so as to limit further rotation of the insulating fixing leg 300. In some embodiments, other limiting structures may be provided to stop rotation of the insulating securing legs 300 when rotated to the extended position. In other embodiments, only one torsion spring 400 may be provided, and the torsion spring 400 may be sleeved on the first rotating shaft 310 or the second rotating shaft 320. In some embodiments, the first elastic member may be replaced by a spring 400 or other suitable first elastic member, where the first elastic member is a spring, the first end of the spring is connected to the housing 100, the second end of the spring is connected to a protrusion disposed on the circumference of the first rotating shaft 310 (and/or the second rotating shaft 320), and the stretching amount of the spring when the insulating fixing leg 300 is in the retracted position is greater than the stretching amount of the spring when the insulating fixing leg 300 is in the extended position, so that the spring may pull the insulating fixing leg 300 by its own elastic force to rotate from the retracted position to the extended position.
The spacing assembly 500 is disposed on the housing 100 and is configured to be able to spacing and de-spacing the insulated stationary feet 300 in the stowed position. When the limiting assembly 500 limits the insulating fixing legs 300 in the retracted position, the limiting assembly 500 limits the insulating fixing legs 300 from rotating from the retracted position to the extended position; when the limiting assembly 500 releases the limit of the insulating fixing leg 300 at the retracted position, the first elastic member can push the insulating fixing leg 300 to rotate from the retracted position to the extended position.
In the embodiment of the present utility model, the limiting assembly 500 includes a limiting member 510 and a toggle button 520 connected to the limiting member 510. The limiting member 510 is located in the housing 100, the first side wall 110 of the housing 100 is provided with a key hole 112 matching with the toggle button 520, and the toggle button 520 is located in the key hole 112 and is capable of moving between the first end and the second end of the key hole 112. The pressing plate 600 is covered on the limiting member 510, so that the limiting member 510 is limited between the pressing plate 600 and the first side wall 110, and the area of the side, facing the first side wall 110, of the limiting member 510 is larger than the area of the key hole 112, so that the limiting member 510 cannot leave the casing through the key hole 112, and therefore, the limiting member 510 can only move along the extending direction of the key hole 112 on the first side wall 110. That is, the user may move the stopper 510 by toggling the toggle button 520 in the button hole 112. When the toggle button 520 is located at the first end of the button hole 112, the limiting member 510 is located at the first position and can be clamped with the insulating fixing leg 300 located at the retracted position, so as to limit rotation thereof, and therefore the first elastic member cannot push the limiting member 510 to rotate from the retracted position to the extended position. When the toggle button 520 is located at the second end of the button hole 112, the limiting member 510 is located at the second position and separated from the insulating fixing leg 300 located at the retracted position, and at this time, the first elastic member can push the limiting member 510 to rotate from the retracted position to the extended position.
In the embodiment of the present utility model, the limiting assembly 500 further includes a second elastic member and a stop wall 540 disposed on the housing 100. The second elastic member is located between the limiting member 510 and the stopping wall 540, and is used for pushing the limiting member 510 to move from the second position to the first position. Specifically, the stop wall 540 is a vertical wall protruding from the inside of the first side wall 110 toward the inside of the housing 100, the second elastic member is a spring 530, a first end of the spring 530 abuts against the limiting member 510, a second end abuts against the first side wall 110, and the compression amount of the spring 530 is smaller when the limiting member 510 is in the first position than when the limiting member 510 is in the second position. So that the spring 530 can push the stopper 510 to move from the second position to the first position by its own elastic force (i.e., toggle the button 520 to move from the second end to the first end of the button hole 112). The provision of the second elastic member enables the stopper 510 to be stably maintained in the first position, thereby enabling the insulating fixing base 300 in the stowed position to be stably maintained in the stowed state. In some embodiments, the second elastic member may be replaced by a metal elastic sheet or other suitable elastic member, where when the second elastic member is a metal elastic sheet, one end of the second elastic member may be fixed on the stop wall 540, and the other end of the second elastic member abuts against the limiting member 510, where the deformation amount of the metal elastic sheet is smaller when the limiting member 510 is in the first position than when the limiting member 510 is in the second position.
In the embodiment of the present utility model, the first end of the insulating fixing leg 300 is provided with a first guiding surface 340 and a first limiting surface 350, and an angle between the first guiding surface 340 and the first limiting surface 350 is an acute angle. The stopper 510 includes a second guide surface 511 and a second stopper surface 512, and an angle between the second guide surface 511 and the second stopper surface 512 is an acute angle. The first limiting surface 350 is perpendicular to the first sidewall 110 when the insulating securing leg 300 is in the extended position, and the first limiting surface 350 is parallel to the first sidewall 110 when the insulating securing leg 300 is in the retracted position. The second limiting surface 512 of the limiting member 510 is parallel to the first sidewall 110. During the process of rotating the insulating fixing leg 300 from the unfolding position to the folding position, the first guiding surface 340 can abut against the second guiding surface 511 and push the limiting piece 510 to move from the first position to the second position; when the insulating fixing base 300 rotates to the retracted position, the first guiding surface 340 is separated from the second guiding surface 511, the second elastic member pushes the limiting member 510 to move from the second position to the first position, the second limiting surface 512 is attached to the first limiting surface 350, and the limiting member 510 limits the insulating fixing base 300 from rotating from the retracted position to the extended position. Therefore, when the user needs to store the insulating fixing leg 300, the limiting assembly 500 can be automatically clamped with the insulating fixing leg 300 only by rotating from the unfolding position to the folding position, so that the insulating fixing leg 300 is stably kept in the folding state, and the user does not need to manually operate the key. When the user needs to expand the insulating fixing leg 300, the first elastic member can push the insulating fixing leg 300 to rotate from the retracted position to the expanded position only by shifting the shifting key 520 from the first end to the second end of the key hole 112, and the operation is convenient.
In the embodiment of the present utility model, the limiting member 510 is engaged with the second limiting surface 512 on the insulating fixing base 300 to limit the rotation of the insulating fixing base 300 from the retracted position to the extended position. In other embodiments, the insulating fixing base 300 is provided with a through hole (i.e., the fixing post 360 is provided with a through hole (corresponding to the through hole) on the side wall of the groove), and the limiting assembly 500 (including the limiting member 510 and the toggle button 520) may be configured to limit the rotation of the insulating fixing base 300 from the retracted position to the extended position by being engaged with the through hole. Specifically, the stopper 510 may include an extension portion that mates with the through hole portion. The moving direction of the stopper 510 (and the toggle button 520) on the first sidewall 110 is configured to coincide with the central axis direction of the through hole portion. When the toggle button 520 is located at the first end of the button hole 112 (i.e., the limiting member 510 is located at the first position), the protruding portion protrudes into the through hole portion of the insulating fixing leg 300 located at the retracted position, and the protruding portion blocks the insulating fixing leg 300 in the rotation direction thereof to limit rotation thereof, so that the first elastic member cannot push the limiting member 510 to rotate from the retracted position to the extended position; when the toggle button 520 is located at the second end of the button hole 112 (i.e., the limiting member 510 is located at the first position), the protruding portion is separated from the through hole portion of the insulating fixing leg 300 located at the retracted position, and no blocking is formed on the protruding portion, so that the first elastic member can push the limiting member 510 to rotate from the retracted position to the extended position.
