DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solutions and advantages of the utility model more clearly understood, the utility model is further described in detail below in conjunction with embodiments and drawings. The schematic implementation manner of the utility model and its description are only used to explain the utility model and are not intended to limit the utility model.

[0026] Please refer to Figures 1 to 4 The present embodiment provides a multifunctional and highly reliable mobile power disk, comprising a cable winding disk 10, wherein a side wall of the cable winding disk 10 is recessed with an annular cable winding groove 11, wherein an input cable (not shown) is wound around the cable winding groove 11, wherein one end of the input cable is provided with a plug (not shown); secondly, a plurality of sockets 20 and a plurality of conversion sockets 21, wherein all of the sockets 20 are embedded in the end surface of one side of the cable winding disk 10, and all of the conversion sockets 21 are detachably embedded in the end surface of the other side of the cable winding disk 10, and each of the conversion sockets 21 is respectively connected to the input cable; thirdly, a plurality of groups of protection connection components are provided, wherein the protection connection components are provided on the end surface of the cable winding disk 10, wherein the protection connection components correspond to the sockets 20 one by one, and wherein the protection connection components include a knife switch 30, a leakage protector 31 and an overheat protector 32 connected in series; and each of the sockets 20 is respectively connected to the input cable through the corresponding protection connection components.

[0027] The utility model provides a multifunctional and highly reliable mobile power supply disk, which adopts a structural integration method to replace the existing parts-distributed distribution box structure, so as to avoid the problem that the parts of the distribution box are relatively dispersed and the connection time is too long. Specifically, it is provided with a winding disk 10 with a plug, and the plug is wound on the winding disk through an input cable, providing an integrated structure installation foundation and input power, and a plurality of sockets 20 and a plurality of conversion sockets 21 are all arranged on the end surface of the winding disk 10 to form an integrated structure, wherein the socket 20 is connected to the plug through a protective connection component, and the knife switch 30 in the protective connection component can be used to control the disconnection and connection of the socket 20, and at the same time, the leakage protector 3 in the protective connection component is used. 1 and the overheat protector 32 ensure the safe operation of the socket 20, thereby meeting the electricity usage regulations of one machine, one switch and one protection; the conversion socket 21 is connected to the plug of the winding disk 10 to cope with different models of external plugs. A plurality of conversion sockets 21 of different models can be provided to enrich the applicable situations, thereby ensuring the basis for coping with integrated connectivity. By providing a detachable connection between the conversion socket 21 and the winding disk 10, the conversion socket 21 can be detachably pulled out to adapt to an external plug that is not located near the winding disk 10, thereby further improving the integrated connection; on this basis, through the mutual cooperation of the above-mentioned components, the multifunctional and highly reliable mobile power disk can effectively solve the problem of long line connection time.

[0028] It should be noted that the number of the conversion sockets 21 is preferably multiple, and the multiple conversion sockets 21 are preferably of different models to adapt to as many external plug models as possible.

[0029] It should be noted that the conversion socket 21 is connected to the plug via a relatively long cable, so that the conversion socket 21 can be pulled out of the cable reel 10 to a certain length, and the relatively long cable can be hidden in the inner cavity of the cable reel 10 .

[0030] In order to facilitate intuitive and timely control of the socket 20 , the protection connection component and the socket 20 are arranged on the same side end surface of the winding reel 10 .

[0031] By arranging the socket 20 and the protective connection assembly on the same side end surface of the winding reel 10, the socket 20 and the corresponding knife switch 30, leakage protector 31 and overheat protector 32 can be arranged in a close area for intuitive distinction and control.

[0032] In order to timely monitor and characterize the power-on status of the socket 20 , the protection connection component further includes an indicator light 33 connected in series.

[0033] In order to cope with as many types of external plugs as possible, the number of the conversion sockets 21 is three, and the three conversion sockets 21 are distributed around the axis of the winding reel 10 in an equilateral triangle.

[0034] For a further explanation of the clamping structure of the conversion socket 21, three embedding grooves 12 are provided on one end face of the wire winding disc 10 where the conversion socket 21 is located, and the embedding grooves 12 correspond to the conversion socket 21 one by one; a pair of opposite groove walls of the embedding groove 12 extend inward at the groove opening to form a clamping edge 121. When the conversion socket 21 is embedded in the embedding groove 12, the clamping edge 121 is in limit clamping connection with the outer surface of the conversion socket 21. The clamping edge can effectively prevent the conversion socket 21 from falling out of the embedding groove 12 unnecessarily.

[0035] To counteract the clamping edge 121 for facilitating the removal of the conversion socket 21, another pair of opposite groove walls of the embedding groove 12 are dug inward to form wedge-shaped finger grooves 122, and the bottom of the finger groove 122 is smoothly connected to the bottom of the embedding groove 12.

[0036] With the above arrangement, when it is necessary to remove the conversion socket 21, just insert the thumb and index finger (or middle finger) into the finger grooves 122 on both sides to effectively clamp the side wall of the conversion socket 21, and then it can be pulled out.

[0037] To further facilitate the use, the above-mentioned multifunctional and highly reliable mobile power supply disc further includes a bracket 40. The bracket 40 is provided with a rotating shaft 41, and the rotating shaft 41 is rotatably connected to the wire winding disc 10 coaxially; when the bracket 40 is supported on a horizontal plane, the rotating shaft 41 is horizontally arranged and the wire winding disc 10 is suspended.

[0038] By setting the bracket 40, the wire winding disc 10 is suspended to facilitate the access and winding of the input cable. By setting the rotating shaft 41, a rotating fulcrum is provided for the suspended wire winding disc 10. On the one hand, it is convenient for the winding and access of the input cable, and on the other hand, it is convenient to adjust the height position and orientation of the socket 20 and the conversion socket 21 to facilitate the connection with an external plug.

[0039] To further improve the structural stability of the bracket 40 and prevent the structure of the bracket 40 from blocking the wire winding disc 10, the bracket 40 includes three structural rods 42 connected in a scattered manner. The three structural rods 42 are located in the same plane. The rotating shaft 41 is provided at the intersection of the three structural rods 42 and is perpendicular to the plane where the three structural rods 42 are located; the end parts of two adjacent structural rods 42 are respectively connected to both ends of a U-shaped bottom frame 43, and the plane where the bottom frame 43 is located is parallel to the rotating shaft 41; the third structural rod 42 is connected with a grip rod 44, the grip rod 44 is parallel to the rotating shaft 41, and a grip sleeve 441 is rotatably sleeved on the grip rod 44; the wire winding disc 10 is suspended above the bottom frame 43, and the grip rod 44 is suspended directly above the wire winding disc 10.

[0040] Through the above arrangement, three structural rods 42 are used to form a triangular surface structure to effectively support the rotating shaft 41 located in the center. The surface structure can avoid obstruction of the winding reel 10 to the greatest extent. On this basis, the base frame 43 can provide a larger supporting surface for stable setting, and the handle 44 can be pressed by hand when in a curve or in use to ensure the stability of the entire device and prevent it from tipping over.

[0041] In order to reduce the weight of the winding drum 10 to facilitate rotation and provide a hidden space for the cable, the interior of the winding drum 10 is hollowed out, and a shaft cylinder 13 is coaxially arranged inside the winding drum 10. The side wall of the shaft cylinder 13 is connected to the inner wall of the winding drum 10 through a plurality of fins 14.

[0042] Through the above arrangement, the weight of the cable reel 10 is reduced by hollowing out, and the cable connected to the conversion socket 21 can be hidden therein. By setting the shaft tube 13, the stability of the rotational connection between the cable reel 10 and the rotating shaft 41 can be ensured, and the fin 14 can improve the heat dissipation effect while providing structural performance.

[0043] Preferably, the plane where the fins 14 are located is coplanar with the axis of the shaft tube 13, and the fins 14 are evenly arranged in a radial shape.

[0044] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only the specific implementation method of the utility model and is not used to limit the protection scope of the utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
