[0015] Preferably, the functional socket also includes a socket panel, which is arranged on the front side of the base and covers the cover bracket; and / or, a wiring terminal is installed in the base, the wiring terminal is connected to a wire, and the functional socket is installed on the dark box.

[0016] The present invention adopts the above technical solution and has the following beneficial effects:

[0017] 1. A plug-proof function module is provided so that the socket has a plug-proof function, and the plug-proof function module can be integrated and installed on a conventional socket to avoid redesigning the socket. The module frame is installed on the base through an opening, and the module frame is installed using the inherent space inside the base opening, and can protrude outward from the outside of the base opening. When there is insufficient space inside the base, it is extended outward to provide installation space for the fixed frame assembly. Furthermore, a cover bracket is provided on the outside of the module bracket, and the cover bracket is connected to the base and covers the base opening. The cover bracket is provided with a module bracket fixing structure, so that the module bracket is fixed on the base. In this way, the plug-proof function module is combined with the original structure of the socket, and they do not affect each other, thereby improving the versatility of installation.

[0018] The connecting position of the heads of the two flaps corresponds to the outside of the socket, and the plug is inserted into the socket from the connecting position of the heads of the two flaps. The flap is connected to a locking member that locks the plug when the plug is installed in place. When the plug is pulled out, the fixed frame assembly is driven to move outward along the guide groove. After moving a set distance, it is limited by the limit member, the plug stops moving outward and the locking member releases the lock on the flap, so that when the plug is inserted into the socket again, the flap is driven to flip and disengage from the plug and unlock, and the plug can be pulled out.

[0019] In this way, when the plug is inserted into the socket, the two flaps flip inward to avoid the plug, and the two movable blocks are driven by the flaps to slide relative to each other in the left and right directions, also making a movement to avoid the plug, so the plug insertion process is smooth; when pulling out the plug, first pull out a part of the plug, then press down to unlock and pull it out, which can prevent the plug from falling off or being pulled out by mistake.

[0020] After the plug is pulled out from the socket, the two movable blocks are reset by moving toward the middle position through the movable block reset member, and the fixed frame reset member pushes the fixed frame assembly to reset inward along the guide groove without affecting the normal plugging and unplugging of the plug next time.

[0021] 2. Use an elastic wall to prevent the flap from turning inward and drive the flap to lock the plug. Since the elastic wall can generate a large locking force, the plug is locked to prevent it from falling off.

[0022] 3. The movable block is U-shaped, so that the two movable blocks are combined into a frame structure, in which the guide column on one movable block is slidably connected to the slide groove on the other movable block to form a slide rail. Since the front and rear side walls of the two movable blocks are correspondingly connected with the slide rail, it is ensured that the two movable blocks and the two connected flaps can slide straight left and right.

[0023] 4. When the plug is inserted into the socket, the front and back of the plug come into contact with the V-shaped spring, causing the V-shaped spring to expand. At the same time, under the action of the plug, the flap drives the two movable blocks to move relative to the left and right directions respectively; after the plug is pulled out of the socket, the V-shaped spring contracts, driving the two movable blocks to move relative to the left and right directions and reset.

[0024] 5. The vertical part is located in the movable groove. Before the flip, the horizontal part is roughly horizontal. When the plug is inserted into the socket, the plug acts on the horizontal part to realize the overall flip of the flap. The vertical part moves in the movable groove and acts on the elastic wall. When the plug is fully inserted through the gap between the horizontal parts of the two flaps, the flap locks the plug under the action of the elastic wall. The flap cannot continue to flip downward after it flips down to a certain angle under the limiting action of the limiting ribs and the fixed frame.

[0025] 6. When the plug is inserted into the socket, the left and right sides of the plug contact the upper inclined surface, pushing the flap to flip downward. When the plug is installed in place and locked by the flap, the vertical wall and the left and right sides of the pin are locked tightly, with a large contact area to ensure reliable locking.

[0026] 7. The limit column extends vertically inward, and the inner end cooperates with the fixed frame to limit the outward movement of the fixed frame. The reset spring abuts against the fixed frame in a naturally extended state. Therefore, when the fixed frame moves outward, the reset spring is first compressed until it abuts against the lower end of the limit column.

[0027] 8. The cover bracket is connected to the base with a snap buckle, which is easy to install.

[0028] 9. The cover bracket is provided with lateral limiting walls and upper limiting walls, wherein the lateral limiting walls are limitedly matched with the outer side surface of the module frame, and the upper limiting walls are limitedly matched with the upper end of the module frame, so that after the cover bracket is connected to the base, the module frame can be fixed.

[0029] These features and advantages of the present invention will be disclosed in detail in the following specific embodiments and drawings.

[0046] Reference Figures 1 to 8 As shown, a functional socket that is easy to install includes a base 3 and a socket 7 installed in the base, and the socket 7 is plugged with a plug 1. The functional socket also includes a plug-off prevention function module, and the plug-off prevention function module includes a module frame 5, a cover bracket 4, and a fixed frame assembly movably installed in the module frame. The outer side of the base 3 is provided with an opening, and the module frame 5 is installed on the base 3 through the opening. The cover bracket 4 is connected to the base 3 and covers the base opening, and the cover bracket 4 is provided with a module frame fixing structure for fixing the module frame 5.

[0047] The fixed frame assembly includes two movable blocks 9, a slide rail and a movable block reset member connecting the two movable blocks 9, and two flaps 8 correspondingly hinged on the two movable blocks. The two movable blocks 9 form a fixed frame, wherein the head connection position of the two flaps is correspondingly located outside the socket, and the plug 1 enters from the head connection position of the two flaps 8 and then inserts into the socket 7. When the plug 1 is inserted into the socket 7, the two flaps 8 are driven to flip inward, and the flaps drive the two movable blocks 9 to slide relative to each other in the left and right directions. The flap 8 is connected to a locking member that allows the flap to lock the plug 1 when the plug is installed in place. A guide groove 50 is provided in the module frame 5, and a limiter and a fixed frame reset member are provided on the cover bracket 4. When the plug is pulled out, the fixed frame assembly is driven to move outward along the guide groove 50, and after moving a set distance, it is limited by the limiter, the plug 1 stops moving outward, and the locking member releases the lock on the flap 8, so that when the plug is inserted into the socket again, the flap 8 is driven to flip and disengage from the plug and unlock, and the plug can be pulled out.

[0048] In this way, when the plug is inserted into the socket, the two flaps flip inward to avoid the plug, and the two movable blocks are driven by the flaps to slide relatively in the left and right directions to avoid the plug, so the plug insertion process is smooth.

[0049] After the plug 1 is pulled out from the socket, the two movable blocks 9 are reset by moving toward the middle position through the movable block reset member, and the fixed frame reset member pushes the fixed frame assembly to reset inward along the guide groove. Therefore, the normal plugging and unplugging of the plug next time is not affected.

[0050] It can be understood that the module frame 5 and the cover bracket 4 have corresponding openings so that the plug can be inserted through the openings.

[0051] Since the anti-plug-off function module is provided, the socket has the function of preventing the plug from falling off. And the anti-plug-off function module can be integrated and installed on a conventional socket to avoid redesigning the socket. The module frame is installed on the base through the opening, and the module frame is installed using the inherent space inside the base opening, and can protrude outward from the outside of the base opening. In the case of insufficient space inside the base, it is extended outward to provide installation space for the fixed frame assembly, and a cover bracket is further provided on the outside of the module bracket. The cover bracket is connected to the base and covers the base opening, and the cover bracket is provided with a module bracket fixing structure, so that the module bracket is fixed on the base. In this way, the anti-plug-off function module is combined with the original structure of the socket, and does not affect each other, thereby improving the versatility of installation.

[0052] As an embodiment, the locking member is an elastic wall 5-1 provided on the module frame 5, and the elastic wall blocks the flap 8 from turning inward and drives the flap to lock the plug 1. Specifically, the elastic wall 5-1 is provided on the bottom wall of the guide groove 50, and the bottom wall of the guide groove 50 is provided with a movable groove 5-3 that cooperates with the flap on one side of the elastic wall, and the bottom wall of the guide groove 50 is provided with a deformation groove 5-2 on the other side of the elastic wall. In this way, when the flap rotates, the bottom of the flap moves in the movable groove, and the elastic wall blocks the flap from turning inward and deforms toward the deformation groove, thereby generating a reaction force to lock the plug. Since the elastic wall can generate a large locking force, it ensures that the plug is locked and prevents it from falling off. The elastic wall is an inclined surface, and the bottom of the flap is provided with an inclined surface that cooperates with the inclined surface of the elastic wall. It can be understood that the elastic wall can also be replaced by a spring or other elastic member.

[0053] Specifically, Figure 6 As shown, the movable block 9 is U-shaped, and the slide rail includes a slide groove 9-3 or a guide column 9-4 provided on the front and rear side walls of the movable block, that is, on the same side (front side, rear side) of the two movable blocks, the guide column on one movable block is slidably connected to the slide groove on the other movable block. In addition, on the same movable block, a guide column is provided on one side (front side or rear side), and a slide groove is provided on the other side. Since the front and rear side walls of the two movable blocks are correspondingly connected with the slide rail, it is ensured that the two movable blocks and the two connected flaps can slide straightly left and right.

[0054] Furthermore, the slide groove 9-3 and the guide post 9-4 are both T-shaped structures, and are set through the front and rear side walls of the movable block. In this way, when the two movable blocks are combined, the guide post on one side of one movable block and the slide groove on the same side of the other movable block are first inserted into each other, and then one of the movable blocks is rotated 180 degrees, and the slide groove on the other side of one movable block and the guide post on the same side of the other movable block are first connected and inserted into each other to form an annular fixed frame. In addition, when the two movable blocks move outward to the maximum position to the left and right, a limit is naturally formed.

[0055] Specifically, Figure 7As shown, the flap 8 is provided with a horizontal portion 801 and a vertical portion 802 connected to the tail end of the horizontal portion and extending downward, the tail end of the horizontal portion is provided with a rotating shaft 8-1 on both the front and rear sides, the movable block 9 is provided with a rotating shaft hole 9-1 matched with the rotating shaft, and the upper end of the vertical portion is provided with a limiting rib 8-2 on both the front and rear sides matched with the fixed frame. The vertical portion 802 is located in the movable groove 5-3, and the inclined surface is located outside the vertical portion 802 and matched with the inclined surface of the elastic wall. Before the horizontal portion 801 is flipped, it is roughly horizontal, and the two inclined surfaces are not attached, with a certain gap. When the plug is inserted into the socket, the plug acts on the horizontal portion to realize the overall flipping of the flap. When flipped to a certain angle, the two inclined surfaces act, and the vertical portion moves in the movable groove and acts on the elastic wall. When the plug is fully inserted through the gap between the horizontal portions 801 of the two flaps, under the action of the elastic wall, the flap locks the plug. Under the limiting action of the limiting rib 8-2 and the fixed frame, the flap cannot continue to be turned downward after turning downward to a certain angle.

[0056] Furthermore, a protrusion 803 is provided at the middle of the head end of the horizontal portion 801, and an upper inclined surface 8031 ​​is provided on the upper side of the protrusion, a vertical wall 8032 is provided in the middle, and a lower arc surface 8033 is provided on the lower side, which is conducive to the interaction between the plug and the protrusion 803. In this way, when the plug is inserted into the socket, the left and right sides of the plug contact with the upper inclined surface, pushing the flap to flip downward, and when the plug is installed in place and locked by the flap, the vertical wall and the left and right sides of the latch are locked, and the contact area is large, ensuring reliable locking.

[0057] As an implementation mode, the movable block reset member is a V-shaped spring 11, which is V-shaped in the middle and has fixed feet at both ends. Both movable blocks 9 are provided with spring holes 9-2, and the fixed feet at both ends of the V-shaped spring are connected to the spring holes 9-2 on the two movable blocks. Specifically, the groove wall of the slide groove 9-3 and the head of the guide column 9-4 are provided with spring holes 9-2. The two sides of the protrusions on the two flaps are combined to form two front and rear avoidance grooves 8-3, and the V-shaped spring is arranged in the avoidance groove. When the plug is inserted into the socket, the front and back of the plug contact with the V-shaped spring, so that the V-shaped spring opens, and at the same time, under the action of the plug, the flap drives the two movable blocks to move relative to each other in the left and right directions; after the plug is pulled out of the socket, the V-shaped spring contracts, driving the two movable blocks to move toward each other in the left and right directions and reset. Of course, it can be understood that the movable block reset member can also be replaced with other forms of springs or other elastic members.

[0058] like Figure 8As shown, in this embodiment, the limiting member is a limiting column 4-2 provided on the cover bracket 4. The fixed frame reset member is a reset spring 4-1 integrally provided on the cover bracket 4, that is, a hole is opened on the cover bracket 4, and the reset spring 4-1 extends inward from the side wall of the hole. The limiting column extends vertically inward, and the inner end cooperates with the fixed frame to limit the outward movement of the fixed frame. The reset spring extends inward for a certain length and may have a certain bend to improve its elasticity, have a large elastic force to realize the reset function, and the reset spring abuts against the fixed frame in a naturally stretched state. Therefore, when the fixed frame moves outward, the reset spring is first compressed until it abuts against the lower end of the limiting column.

[0059] To install the cover bracket, Figure 8 As shown, the outer circumferential side of the cover bracket 4 is provided with a buckle 4-3, and the base 3 is provided with a cam 3-1, and the buckle 4-3 cooperates with the cam 3-1. Specifically, the buckle 4-3 is an L-shaped structure, including a horizontal portion and a vertical portion, and there is a gap between the vertical portion and the outer side of the cover bracket, and a slot 4-31 is provided on the buckle. When installing the cover bracket, the cover bracket is inserted into the base, wherein the vertical portion is located outside the base, and the horizontal portion is limitedly matched with the upper side of the base mouth. The vertical portion opens outward and passes through the cam under the push of the cam inclined surface, and after passing through the cam, it shrinks inward and cooperates with the limited step surface of the cam. The cover bracket 4 is assembled with the base, and the module frame is fixed at the same time.

[0060] Specifically, the module frame fixing structure includes a lateral limiting wall 4-5 and an upper limiting wall 4-4, wherein the lateral limiting wall 4-5 is limitedly matched with the outer side surface of the module frame, and the upper limiting wall 4-4 is limitedly matched with the upper end of the module frame. In this way, the module frame is fixed in the base. Therefore, after the cover bracket is connected to the base, the module frame can be fixed.

[0061] In addition, the functional socket further comprises a socket panel 2 , which is arranged on the front side of the base and covers the cover bracket 4 .

[0062] The fixing frame assembly is assembled into the module frame 5, and then covered with the cover bracket 4, together forming an anti-plug falling-off functional module, which can be installed on different sockets. The falling-off functional module and the base together form a base assembly, and the base assembly is fixed with the socket panel 2 through a buckle to form a socket panel assembly, and the socket panel 2 is arranged on the front side of the base and covers the cover bracket 4. The base 3 is installed with a wiring terminal 6, and the wiring terminal 6 is connected to a wire, and the functional socket is installed on the dark box.

[0063] like Figure 1As shown: the terminal block 6 is placed in the base 3, the socket 7 is placed in the base 3, the module frame 5 is placed in the base 3, the fixed frame assembly is placed in the module frame 5, the cover bracket 4 is engaged with the base 3, the base 3 is wired and installed on the dark box, and the socket panel 2 is inserted into the base 3.

[0064] like Figure 2 As shown: the plug 1 is inserted into the socket, the front and back sides of the plug contact with the V-shaped spring 11 to open the spring, and the left and right sides of the plug contact with the flap 8 to move the flap left and right. Under the action of the plug, the flap drives the two movable blocks 9 on the fixed frame to move left and right and open respectively. The plug 1 is installed in place and locked by the flap 8, and the flap drives the elastic wall 5-1 to deform toward the position of the deformation groove 5-2.

[0065] like Figure 3 As shown: when the plug 1 is pulled out, the fixed frame assembly moves outward together, and contacts the limit column 1-1 after moving to a certain distance, the plug 1 stops moving outward, the plug 1 is locked, the flap 8 flips outward and disengages from the elastic wall 5-1, and the elastic wall returns to its original position without the influence of external force.

[0066] like Figure 4 As shown: the plug 1 is inserted into the socket again, the flap 8 is flipped at an angle, disengaged from the plug 1 and unlocked, and the plug 1 is pulled out.

[0067] like Figure 5 As shown: after the plug 1 is pulled out, the plug 1 is no longer in contact with the V-shaped spring 11, and the V-shaped spring 11 contracts toward the middle, driving the fixed frame assembly to contract toward the middle. After the fixed frame assembly contracts, the reset spring 4-1 pushes the fixed frame assembly to the initial position.

[0068] It is understandable that the socket in this embodiment is not only applicable to three-hole sockets, but also to five-hole sockets or other multi-hole sockets. For a three-hole socket, the fixing frame component can be set corresponding to one of the holes, usually corresponding to the grounding hole.

[0069] The above is only a specific embodiment of the invention, but the protection scope of the invention is not limited thereto. Those skilled in the art should understand that the invention includes but is not limited to the contents described in the drawings and the above specific embodiments. Any modification that does not deviate from the functional and structural principles of the invention will be included in the scope of the claims.
