[0002] The installation of wall-mounted electrical appliances (such as fans, lamps, etc.) has always been a headache. When installing an electrical appliance, you have to bear the weight of the appliance with your hands and connect the wires at the same time, which increases the difficulty of installation and the danger.

[0003] Therefore, how to realize a lamp connector with reasonable structural design, quick, safe and reliable connection, and convenient disassembly and maintenance, is a technical problem to be solved urgently in the industry. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a convenient installation device, which can quickly install electrical appliances such as lamps and lanterns, and has a locking function to effectively prevent the electrical appliances such as lamps and lanterns from loosening and falling.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a convenient installation device, comprising a plug for connecting an external electrical appliance and a socket for connecting an external power line, the plug being detachably connected to the socket and being used to be electrically connected to the socket so that the external electrical appliance is fixed and connected to the external power line, a socket, the socket being provided with an elongated hole, the elongated hole having a first area and a second area along the length extension direction, in the orthographic projection of the horizontal plane of the elongated hole, the first area is wider than the second area, and one side wall of the second area is provided with a locking groove; a plug, the plug being provided with a locking member, the locking member being able to extend and retract from the side of the plug, the locking member extending from the side of the plug in a natural state, the locking member retracting toward the plug when subjected to a force toward the plug, and the locking member extending from the side of the plug after the force disappears; the first area at least allows the locking member to partially extend, and when the locking member moves from the first area into the second area, the locking member retracts due to the width of the second area until it moves to align with the locking groove and extends into the locking groove.

[0006] After the plug is electrically connected to the appliance and the socket is electrically connected to the power line, the appliance can be installed and powered on by directly docking the plug with the socket, which is convenient and quick. At the same time, the present solution also designs a locking member and a locking groove. Through the cooperation of the locking member and the locking groove, the plug will not loosen after docking with the socket, effectively preventing the plug from being separated from the socket and the appliance from falling off. When assembling, it is only necessary to move the locking member into the locking groove, and no additional installation steps are added, which is convenient to install. When disassembling, the locking member is pressed by hand to make it fall out of the locking groove before disassembling, which is convenient and quick.

[0007] Preferably, the plug is provided with a hanging ear, the first area allows the hanging ear to pass through, and when the locking member extends into the locking groove, the edge of the second area restricts the hanging ear from passing through the elongated hole.

The first elastic member can preferably be a spring, and the extension and retraction of the locking member are achieved by the spring.

[0015] Preferably, the elongated hole is in an arc shape, and when the plug is docked with the socket, the locking member is allowed to slide from the first area into the second area and extend into the locking groove by rotating the plug.

[0022] The second elastic member is preferably a spring, which abuts against the conductive sheet through the spring so that after the plug is connected to the socket, the conductive sheet abuts against the conductive sheet of the male terminal block with a certain force through the spring, thereby enhancing the conduction stability.

[0039] In order to facilitate the understanding of those skilled in the art, the present invention is further described below in conjunction with embodiments, and the contents mentioned in the implementation modes are not intended to limit the present invention.

[0040] like Figure 1As shown, a convenient installation device includes a plug 1 for connecting an external electrical appliance and a socket 2 for connecting an external power line. The plug 1 is detachably connected to the socket 2 and is used to be electrically connected to the socket 2 so that the external electrical appliance is fixed and connected to the external power line.

[0041] The socket 2 includes a hanging plate 3 and a female terminal block 4 fixed to the hanging plate 3 by screws. The hanging plate 3 is provided with an arc-shaped long hole 31 and other fixing holes 34. The socket 2 is fixed to the wall or ceiling through the other fixing holes 34. The plug 1 includes a bracket 5 and a male terminal block 6 fixed to the bracket 5 by screws. The bracket 5 is designed to match the connection position of the electrical appliance and thus fix the plug 1 to the electrical appliance. During installation, the plug 1 on the electrical appliance is aligned with the socket 2 on the wall or ceiling and inserted, and the electrical appliance is rotated at a certain angle, so that the plug 1 is rotated at a certain angle relative to the socket 2 to complete the installation.

[0042] like Figures 2 to 4 As shown, the female terminal block 4 is fixed on the hanging plate 3 by screws. The hanging plate 3 is a circular plate with a certain thickness. The hanging plate 3 has a docking hole 32. After the female terminal block 4 is fixed on the hanging plate 3, the circular socket 41 of the female terminal block 4 is aligned with the docking hole 32. When the plug 1 is docked with the socket 2, the circular plug-in portion 61 of the plug 1 passes through the docking hole 32 and is inserted into the circular socket 41, thereby allowing the conductive sheet 11 of the plug 1 to contact and conduct with the conductive sheet 21 of the socket 2. The hanging plate 3 is also provided with two arc-shaped long holes 31. The two arc-shaped long holes 31 are located on both sides of the docking hole 32 and are arranged oppositely. The arc-shaped long hole 31 has a first area 311 and a second area 312. In the orthographic projection of the horizontal plane of the long hole 31, the first area 311 is wider than the second area 312. The so-called width is the width between the two long sides of the arc-shaped long hole 31. The hole wall of the second area 312 is provided with a locking groove 33. Specifically, the locking groove 33 is located on a side of the second area 312 .

[0043] like Figure 3 As shown, the female terminal block 4 includes a shell 42, and the shell 42 is provided with a cavity 44 for accommodating two conductive wire locks 43. A conductive sheet 21 is fixed on the conductive wire lock 43. The shell 42 has three openings connected to the cavity 44, two of which 45 and 46 correspond to the conductive wire locks 43, and the remaining opening is located on the bottom surface of the shell 42. The opening is designed as a circular socket 41. One end of the conductive sheet 21 is fixed by the conductive wire lock 43 for contacting and conducting the inserted wire, and the other end of the conductive sheet 21 extends to the circular socket 41 to be exposed. The shell 42 is also connected to a sealing cover 47 for covering the cavity 44.

[0044] like Figures 9 to 10As shown, in some other embodiments, the female terminal block 4 does not adopt the design of the conductive wire locker 43, but instead realizes the compression of the inserted wire by designing a wrench 7 and other structures to ensure the stable conduction between the conductive sheet 75 and the wire. Specifically, the housing 74 of the female terminal block 4 is provided with a cavity 76 for installing the conductive sheet 75, and the housing 74 is provided with two openings 77 for inserting power lines connected to the cavity 76, two openings 78 for partially exposing the wrench 7, and a circular socket 41 located on the bottom surface of the housing, one end of the conductive sheet 75 is exposed at the circular socket 41, and the other end of the conductive sheet 75 is exposed at the power line socket The opening 77 for insertion is inserted, and the cavity 76 is provided with a wrench 7, a pressing spring piece 71 and a first shaft 72. The pressing spring piece 71 is U-shaped and sleeved on the first shaft 72. The wrench 7 is L-shaped and has a second shaft 73 in the middle. One end of the wrench 7 extends out from the corresponding opening 78. The end 79 of the wrench 7 exposed from the opening 78 is pressed by hand, and the wrench 7 rotates along the second shaft 73. The inner end 70 of the wrench 7 pushes the pressing spring piece 71 to rotate along the first shaft 72, so that one end of the pressing spring piece 71 approaches the conductive sheet 75 to press the wire extending from the opening 77 onto the conductive sheet 75, thereby effectively ensuring the stability of conductivity.

[0045] like Figures 9 to 10 As shown, in some other embodiments, the female terminal block 4 may add a spring 711 between the conductive sheet 75 and the inner wall of the cavity 76, and the spring 711 provides a force to the conductive sheet 75 toward the circular socket 41, so that the conductive sheet 75 can better contact and conduct with the conductive sheet 11 on the plug 1.

[0046] like Figures 5 to 6 As shown, the male terminal block 6 is fixed to the bracket 5 by screws. The bracket 5 is composed of a base 51 and a vertical portion 52 extending from the base 51. The vertical portion 52 has two portions located on both sides of the base 51 and opposite to each other. The free end of the vertical portion 52 has a hanging ear 53. The hanging ear 53 is extended in the extending direction of the locking member 62. The vertical portion 52 also has a telescopic hole 54 located below the hanging ear 53. The locking member 62 is installed on the male terminal block 6. The male terminal block 6 is installed on the base 51 and the locking member 62 is aligned with the telescopic hole 54 of the vertical portion 52. The locking member 62 is extended and retracted by passing through the telescopic hole 54.

[0047] like Figure 6As shown, the male terminal block 6 includes a shell 63, and the shell 63 is provided with two cavities 65 for accommodating two conductive wire lockers 64, two cavities 66 for respectively accommodating two locking members 62, and a cavity 68 for accommodating a grounding conductive column 67. The male terminal block also includes a compression spring 617, which can be located inside the cavity 68. One end of the compression spring 617 is connected to the grounding conductive column 67, and the other end is connected to the shell 63 to drive the grounding conductive column 67 to extend out of the cavity 68. After the male terminal block 6 is connected to the female terminal block 4, the conductive column 67 contacts the hanging plate 3, and the hanging plate 3 forces the conductive column 67 to retreat into the cavity 68, and the compression spring 617 is compressed. The compression spring 617 applies force to the conductive column 67 to increase the pressure between the grounding conductive column 67 and the hanging plate 3, thereby reducing the contact resistance between the grounding conductive column 67 and the hanging plate 3. The housing 63 is also provided with three openings connected to the cavity 65 of the conductive wire locker 64, wherein two openings 69 and 60 correspond to the two cavities 65 accommodating the conductive wire locker 64 for inserting wires into the conductive sheet 11 on the conductive wire locker 65, and the remaining opening is located at the circular plug-in portion 61 on the top surface of the housing, and the conductive sheet 11 fixed by the conductive wire locker 65 extends to the circular plug-in portion 61 and is exposed through the opening, so that when the circular plug-in portion 61 is docked with the circular socket 41, the conductive sheet 11 of the circular plug-in portion 61 is in contact with the conductive sheet 21 of the circular socket 41 for conduction;

[0048] like Figure 6 As shown, the housing 63 is further provided with two cavities 66 corresponding to the two locking members 62 respectively, the cavity 66 has an opening 611, a spring 612 is provided in the cavity 66, one end of the spring 612 abuts against the locking member 62, and the other end of the spring 612 abuts against the bottom wall of the cavity 66, so that the locking member 62 can extend and retract along the direction of the opening 611, and travel grooves 613 are provided on both sides of the cavity 66, and the part of the locking member 62 located in the cavity 66 is provided with a convex portion 614 corresponding to the travel groove 613, and when the locking member 62 reciprocates along the direction of the opening 611 of the cavity 66, the cooperation between the convex portion 614 and the travel groove 613 prevents the locking member 62 from completely escaping from the opening 611;

[0049] like Figures 5 to 7As shown, the side wall 615 of the locking member 62 facing the locking groove 33 is provided with a limiting groove 616, which is located at the top of the locking member 62 and is L-shaped extending to the top surface of the locking member 62. When the locking member 62 extends into the locking groove 33, the bottom surface of the limiting groove 616 can abut against the lower edge of the locking groove 33, and the hanging ear 53 overlaps the upper edge of the locking groove 33, that is, the bottom wall of the limiting groove 616 and the hanging ear 53 jointly clamp the edge of the locking groove 33, and the hanging ear 53 and the limiting groove 616 of the locking member 62 bite the edge of the locking groove 33, effectively limiting the upward and downward movement of the plug 1, and the simple structure enhances the stability of the plug 1 and the socket 2 after docking. It should be noted that the edge of the locking groove 33 is not completely bitten, and a certain floating space is allowed to be left, which is convenient for installation and alignment.

[0050] like Figure 1 and 8 As shown, the docking installation process of the plug 1 and the socket 2, the female terminal block 4 is fixed to the hanging plate 3 by screws, and the hanging plate 3 is fixed to the wall or ceiling by its other fixing holes 34 with screws and other parts, the male terminal block 6 is fixed to the bracket 5 by screws, and the bracket 5 is fixed to the electrical appliance by screws and other parts, and the male terminal block 6 on the electrical appliance is aligned with the female terminal block 4 on the wall or ceiling and inserted. At this time, the circular plug-in portion 61 of the male terminal block 6 is inserted into the circular socket 41 of the female terminal block 4, the vertical portion 52 of the bracket 5 extends into the first area 311 of the arc-shaped long hole 31 of the hanging plate 3, and the vertical portion 52 extends into the first area 31 1, let the hanging ear 53 at the free end of the vertical portion 52 pass through the first area 311 and be located above the hanging plate 3, let the telescopic hole 54 of the vertical portion 52 at least partially align with the hole wall of the first area 311, and then let the limiting groove 616 of the locking member 62 align with the hole wall of the first area 311. After the plug-in is completed, rotate the electrical appliance to rotate the male wiring seat 6 relative to the female wiring seat 4. The male wiring seat 6 rotates so that the locking member 62 and the hanging ear 53 move into the second area 312, and the locking member 62 aligns with the locking groove 33 and extends into it. The hanging ear 53 overlaps the second area 312, i.e., the upper edge of the locking groove 33, to complete the locking and fixing installation. When disassembling, it is necessary to manually press the two locking members 62 to make the locking members 62 disengage from the locking grooves 33 and rotate in the opposite direction, so that the locking members 62 and the hanging ears 53 enter the first area 311 from the second area 312, and pull the locking members 62 and the hanging ears 53 in a direction perpendicular to the rotation direction to make the locking members 62 and the hanging ears 53 withdraw from the first area 311 and disengage the plug 1 from the socket 2.

[0051] In the first area 311 and the second area 312 of the hanging plate 3, the wider first area 311 allows the locking member 62 and the hanging ear 53 on the plug 1 to pass through, and the narrower second area 312 causes the locking member 62 to retract until it is aligned with the locking groove 33 and then extends to achieve a locking effect. At the same time, the narrower second area 312 can clamp the vertical portion 52 on the bracket 5 to a certain extent, and also allow the hanging ear 53 to have an overlapping position, which greatly enhances the connection stability of the plug 1 after docking with the socket 2. Specifically, as Figure 2 and Figure 4 As shown, the end 311 of the second area 312 close to the first area 311 has an inclined surface 3111, and the inclined surface 3111 is used to abut the locking member 62, so that the locking member 62 automatically retracts during the process of moving from the first area 311 to the second area 312. The end of the locking groove 33 close to the first area 311 is provided with a plane 331, and the plane 331 is used to engage with the locking member 62 to limit the retraction of the locking member 62, so that the locking member 62 cannot automatically withdraw after entering the locking groove 33, thereby limiting the locking member 62 from automatically entering the first area 311 from the second area 312.
