[0013] The present application also provides a method for using the rotating table to solve the above problems, comprising:

[0014] providing a common rotating table;

[0015] removing the upper table plate of the rotating table;

[0016] sleeving the annular butt joint assembly of the power connector between the rotating support seat of the upper table plate and the lower table plate;

[0017] aligning the center of the annular butt joint assembly with the center of the rotating support seat;

[0018] adjusting the height of the annular butt joint assembly, covering the upper table plate, and making one of the first cover and the second cover of the annular butt joint assembly at least partially abut the lower table plate, and the other at least partially abut the upper table plate and rotate with the upper table plate.

[0019] Compared with the prior art, the rotating table and the manufacturing method thereof have the following advantages:

[0020] 1. The rotating table of the present invention includes an upper tabletop, a lower tabletop, a rotating support base disposed between the upper and lower tabletops, and a power connector. The upper tabletop is rotatable relative to the lower tabletop. The power connector is sleeved on the rotating support base and simultaneously abuts against the upper and lower tabletops. The power connector includes an annular docking assembly, which includes a first cover and a second cover rotatably connected. An annular conductive track and a conductive contact are respectively disposed within the first and second covers. When the first and second covers rotate relative to each other, the conductive contact moves along the conductive track. In use, at least one of the first and second covers abuts against the lower tabletop, and at least a portion of the other abuts against the upper tabletop and rotates with the upper tabletop. When the upper tabletop rotates, it drives the cover abutting against the upper tabletop to rotate, thereby causing the first and second covers to rotate relative to each other. The conductive contact moves along the conductive track, ensuring that the conductive contact remains electrically connected to the conductive track. In this specific embodiment, at least a portion of the first cover abuts against the lower tabletop, and at least a portion of the second cover abuts against the upper tabletop. One of the conductive contact and the conductive track is electrically connected to the appliance to be used, and the other is electrically connected to an external power source. This allows for convenient use of appliances placed on the upper table. Compared to traditional methods, where the wires connecting the appliance and the external power source can become tangled or wrapped around the rotating table, posing a potential electrical hazard, this power connector optimizes the circuit design. It ensures that the appliance remains electrically connected to the first cover against the upper table during rotation, while the first cover and the second cover rotate relative to each other and maintain an electrical connection. The second cover is then electrically connected to the external power source. In other words, the electrical connection between the appliance and the external power source is achieved through a ring-shaped docking assembly. The wires between them will not become tangled or wrapped around the rotating table, enabling convenient use of appliances on the rotating table.

[0021] 2. Of the surfaces of the first cover and the second cover that are away from the second cover, one is provided with an elastic adjustment member, and the other is provided with a soft rubber. Both the elastic adjustment member and the soft rubber can improve the stability of the power connector's fit with the rotating table.

[0022] 3. The present invention has two or three conductive tracks, each of which abuts against at least one conductive contact, so that the power connector can be connected to a three-hole socket or a two-hole socket, making it convenient for the power connector to be used with electrical appliances that carry three-prong plugs and two-prong plugs.

[0023] 4. The conductive tracks of the present invention are arranged in a concentric ring and are insulated from each other, so that the conductive contact can always abut against the ring conductive track during the rotation of the first cover relative to the second cover.

[0024] 5. The power connector of the present application further comprises a plug and a socket, the plug and the socket are connected with the conductive track and the conductive contact through wires respectively. During the rotation of the second cover relative to the first cover, the conductive contact moves on the conductive track, so that the plug and the socket are always electrically connected, realizing the function of convenient use of electrical appliances on the rotating table.

[0025] 6. The annular docking assembly of the present application comprises a center through hole, the diameter of the center through hole is slightly larger than the diameter of the rotating support base. The side surface of the first cover and the second cover towards the center through hole is provided with a support foam. The support foam is beneficial to prevent the side surface of the annular docking assembly towards the center through hole from directly rubbing against the rotating support base of the rotating table during the rotation of the first cover relative to the second cover, protecting the annular docking assembly and improving the service life of the power connector. The support foam can also dynamically adjust the position of the annular docking assembly and the rotating support base of the rotating table. Specifically, the position of the center of the annular docking assembly is adjusted to coincide with the position of the center of the rotating support base, facilitating the use of the power connector with rotating tables of multiple specifications.

[0026] 7. The conductive contact of the present application comprises a bracket and a roller, the bracket is provided with a mounting groove, and the roller is rotatably connected in the mounting groove and partially exposed from the mounting groove to contact the conductive track. The roller can make the conductive contact roll on the conductive track, which can reduce the friction between the conductive contact and the conductive track compared with sliding, thereby prolonging the service life of the power connector.

[0027] 8. Two rollers are arranged in the mounting groove, and the rollers on the same conductive contact abut against the same conductive track. Compared with arranging a single roller, this arrangement can improve the stability of the abutment between the conductive contact and the conductive track, and further improve the stability of the use of the power connector.

[0028] 9. The rim of the roller is formed with an arc-shaped notch, the cross section of the conductive track is circular, the diameter of the arc-shaped notch is the same as the diameter of the cross section of the conductive track, and the conductive track abuts against the arc-shaped notch and is attached to the inner wall of the arc-shaped notch. On the one hand, the conductive contact will not be deviated in the direction perpendicular to the rotation direction of the conductive contact under the action of centrifugal force during the rotation of the conductive contact on the conductive track, and on the other hand, the arc-shaped notch can increase the contact area between the conductive contact and the conductive track, thereby improving the stability of the power connector.

[0029] 10. The present application further provides a manufacturing method of a rotating table, which has the same beneficial effects as the above-mentioned rotating table, and will not be described here. BRIEF DESCRIPTION OF DRAWINGS

[0047] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0048] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only.

[0049] Please refer to the accompanying drawings Figures 1-4The first embodiment of the present application provides a rotary table 7, which comprises an upper table plate 71, a lower table plate 73, a rotary supporting seat 72 and a power connecting piece 74 arranged between the upper table plate 71 and the lower table plate 73. The upper table plate 71 is rotatable relative to the lower table plate 73. The power connecting piece 74 is sleeved on the rotary supporting seat 72 and simultaneously abuts against the upper and lower table plates. The power connecting piece 74 comprises a ring-shaped butt joint assembly 11, which comprises a first cover body 111 and a second cover body 112 rotatably connected. Ring-shaped conductive tracks 113 and conductive contact pieces 114 are respectively arranged in the first cover body 111 and the second cover body 112. When the first cover body 111 and the second cover body 112 rotate relative to each other, the conductive contact pieces 114 move along the conductive tracks 113. In use, one of the first cover body 111 and the second cover body 112 at least partially abuts against the lower table plate 73, and the other at least partially abuts against the upper table plate 71 and rotates with the upper table plate 71. When the upper table plate 71 rotates, the cover body abutting against the upper table plate 71 is driven to rotate, so that the first cover body 111 and the second cover body 112 also rotate relative to each other. The conductive contact pieces 114 move along the conductive tracks 113 to keep the conductive contact pieces 114 in electrical connection with the conductive tracks 113. In this embodiment, the first cover body 111 at least partially abuts against the lower table plate 73, and the second cover body 112 at least partially abuts against the upper table plate 71. One of the conductive contact pieces 114 and the conductive tracks 113 is electrically connected with an electric appliance to be used, and the other is electrically connected with an external power supply. Thus, the electric appliance placed on the upper table plate 71 can be conveniently used. Compared with the conventional use mode, in which the wires connected between the electric appliance and the external power supply are wound with each other or on the rotary table 7, causing an electrical hazard, the power connecting piece 74 optimizes the circuit design, so that the electric appliance is always electrically connected with the first cover body 111 abutting against the upper table plate 71 during the rotation of the upper table plate 71. The first cover body 111 rotates relative to the second cover body 112 and is always electrically connected with the second cover body 112. The second cover body 112 is electrically connected with the external power supply. That is, the electric connection between the electric appliance and the external power supply is realized through the ring-shaped butt joint assembly. The wires will not be wound with each other or on the rotary table 7, and the function of conveniently using the electric appliance on the rotary table 7 is realized.

[0050] Further, the conductive tracks 113 are generally made of conductive material, preferably metal, such as iron, copper and other metal conductive materials. In this embodiment, the material of the conductive tracks 113 is copper. The material of the conductive contact pieces 114 is also conductive material, preferably graphite or metal. In this embodiment, the material of the conductive contact pieces 114 is copper.

[0051] Further, one of the surface of the first cover 111 away from the second cover 112 and the surface of the second cover 112 away from the first cover 111 is provided with an elastic adjusting piece 1116, and the other is provided with a soft glue 1126. The elastic adjusting piece 1116 and the soft glue 1126 can improve the stability of the power connection 74 and the rotating table 7.

[0052] Further, the number of the conductive tracks 113 is 2 or 3, and at least one conductive contact 114 is abutted on each conductive track 113. In the embodiment, one conductive contact 114 is abutted on each conductive track 113, so that the power connection 74 can be connected with a three-hole socket or a two-hole socket, and the power connection 74 can be conveniently used with an appliance with a three-pin plug or a two-pin plug.

[0053] Further, the conductive tracks 113 are arranged in concentric annular shapes and are insulated from each other, so that the conductive contacts 114 can always abut on the annular conductive tracks 113 during the rotation of the first cover 111 relative to the second cover 112.

[0054] As an optional embodiment, a plurality of conductive contacts 114 are abutted on a single conductive track 113, and only one of the conductive contacts 114 is electrically connected with an external power source or an appliance to be used, and the remaining conductive contacts 114 are used as spare elements, so that the damaged conductive contact 114 can be replaced in time.

[0055] Further, when the number of the conductive contacts 114 is 2, the positions of the two conductive contacts 114 are arranged such that the included angle between the line connecting the two conductive contacts 114 and the center of the conductive track 113 is 180 degrees; and when the number of the conductive contacts 114 is 3, the positions of the three conductive contacts 114 are arranged such that the included angles between the line connecting the three conductive contacts 114 and the center of the conductive track 113 are 120 degrees. In this way, the influence between the conductive contacts 114 can be effectively eliminated, and the stability of the power connection 74 can be improved.

[0056] It can be understood that, in order to prevent the direct electrical connection between the conductive contacts 114 from causing the power connection 74 to be short-circuited, the distance between the conductive contacts 114 should be relatively far, that is, the included angle between the line connecting the conductive contact 114 and the center of the conductive track 113 is not less than 90 degrees.

[0057] Further, when the number of the conductive tracks 113 is 2, one of the conductive tracks 113 is connected with a live wire of an external power source, and the other is connected with a zero wire of the external power source; and when the number of the conductive tracks 113 is 3, one of the conductive tracks 113 is connected with a live wire of an external power source, one is connected with a zero wire of the external power source, and one is connected with a ground wire of the external power source.

[0058] Further, the power connection 74 further comprises a plug 12 and a socket 13, which are connected with the conductive track 113 and the conductive contact 114 through wires respectively. During the rotation of the second cover 112 relative to the first cover 111, the conductive contact 114 moves on the conductive track 113, so that the plug 12 and the socket 13 are always electrically connected, realizing the function of conveniently using electrical appliances on the rotating table. In the specific embodiment, the conductive contact 114 is connected with the socket 13, and the conductive track 113 is connected with the plug 12.

[0059] Further, the annular docking assembly 11 comprises a center through hole 16 in the middle, and the diameter of the center through hole 16 is slightly larger than the diameter of the rotating support seat 72. The first cover 111 and the second cover 112 are both provided with a support foam 117 on the side surface facing the center through hole 16. The support foam 117 is beneficial to prevent the side surface of the annular docking assembly 11 facing the center through hole 16 from directly rubbing against the rotating support seat 72 of the rotating table 7 during the rotation of the first cover 111 relative to the second cover 112, thereby protecting the annular docking assembly 11 and improving the service life of the power connection 74. The support foam 117 can also dynamically adjust the positions of the annular docking assembly 11 and the rotating support seat 72 of the rotating table 7. Specifically, the positions of the centers of the annular docking assembly 11 and the rotating support seat 72 are adjusted to coincide, thereby facilitating the cooperation of the power connection 74 with rotating tables 7 of multiple specifications.

[0060] Please refer to Figure 5 and Figure 6 In the specific embodiment, the adjacent conductive tracks 113 are insulated by the insulating partition plates 115. The partition plates 115 protect the conductive tracks 113 to a certain extent and prevent the conductive tracks 113 from being too close to each other and causing a short circuit of the power connection 74.

[0061] Please refer to Figure 7 and Figure 8 The inner surface of the second cover 112 is provided with a limiting column 1124, and the conductive contact 114 is provided with a limiting hole 1141, and the limiting column 1124 penetrates into the limiting hole 1141. The conductive contact 114 can rotate together with the second cover 112 through the cooperation of the limiting hole 1141 and the limiting column 1124, which is beneficial to the realization of the function of the power connection 74.

[0062] It can be understood that the movement linkage mode of the conductive contact 114 and the second cover 112 is not limited to the cooperation of the limiting column 1124 and the limiting hole 1141, but can also be that the conductive contact 114 is clamped on the inner surface of the second cover 112, or that the conductive contact 114 is threadedly connected to the second cover 112, etc.

[0063] Further, the limiting column 1124 is sleeved with a second elastic member 1146, and the opposite ends of the second elastic member 1146 abut against the conductive contact 114 and the second cover body 112 respectively. The second elastic member 1146 is compressed to make the conductive contact 114 always abut against the conductive track 113, preventing the power connector 74 from being disconnected due to unstable abutment of the conductive contact 114 and the conductive track 113.

[0064] Please refer to Figure 9 and Figure 10 The conductive contact 114 comprises a support 1142 and a roller 1143, the support 1142 is provided with a mounting groove 1144, and the roller 1143 is rotatably connected in the mounting groove 1144 and partially exposed from the mounting groove 1144 to contact the conductive track 113. The roller 1143 is arranged to make the conductive contact 114 roll on the conductive track 113, which can reduce the friction between the conductive contact 114 and the conductive track 113 compared with sliding, and is beneficial to prolong the service life of the power connector 74.

[0065] Of course, the conductive contact 114 can also be arranged in sliding contact with the conductive track 113, as long as the conductive contact 114 always contacts the conductive track 113 during use of the power connector 74.

[0066] Further, two rollers 1143 are arranged in the mounting groove 1144 at intervals, and the rollers on the same conductive contact 114 abut against the same conductive track 113, which is beneficial to improve the stability of the abutment between the conductive contact 114 and the conductive track 113, and further improve the stability of the use of the power connector 74.

[0067] Of course, a single roller 1143 or multiple rollers 1143 can also be arranged in the mounting groove 1144, as long as the conductive track 113 always abuts against the roller 1143 during use of the power connector 74.

[0068] Further, the rim of the roller 1143 is formed with an arc-shaped notch 1145, the cross section of the conductive track 113 is circular, the diameter of the arc-shaped notch 1145 is the same as the diameter of the cross section of the conductive track 113, and the conductive track 113 abuts against the arc-shaped notch 1145 and is attached to the inner wall of the arc-shaped notch 1145. On the one hand, the conductive contact 114 will not be deviated in the direction perpendicular to the rotation direction of the conductive contact 114 due to the centrifugal force during rotation of the conductive contact 114 on the conductive track 113, and on the other hand, the arc-shaped notch 1145 can increase the contact area between the conductive contact 114 and the conductive track 113, and improve the stability of the power connector 74.

[0069] In use, the plug 12 is electrically connected with the external power supply, and the socket 13 is placed on the upper table plate 71, so that the upper table plate 71 is relatively static during the rotation of the lower table plate 73, and the socket 13 is always live. The electric appliance only needs to be connected with the socket 13 to achieve the use of the electric appliance placed on the upper table plate 71, and the wires between the electric appliance and the plug 12 will not be entangled with each other or on the rotating table 7.

[0070] Please refer to Figure 11 The second embodiment of the present application provides a use method of the rotating table 7, comprising:

[0071] S1, providing a common rotating table, which comprises upper and lower table plates 71, 73 that can be relatively rotated, and a rotating support seat 72 arranged between the upper and lower table plates;

[0072] S2, the annular butt joint assembly 11 of the power supply connecting piece 74 is sleeved on the rotating support seat 72 between the upper and lower table plates, and one of the first cover body 111 and the second cover body 112 of the annular butt joint assembly 11 at least partially abuts the lower table plate 73, and the other at least partially abuts the upper table plate 71 and rotates with the upper table plate 71.

[0073] Specifically, the annular butt joint assembly 11 of the power supply connecting piece 74 is sleeved on the rotating support seat 72 between the upper and lower table plates, further comprising removing the upper table plate 71 of the rotating table, and then sleeving the annular butt joint assembly 11 on the rotating support seat 72.

[0074] Further, after the annular butt joint assembly 11 is sleeved on the rotating support seat 72, the following steps are further included:

[0075] The center of the annular butt joint assembly 11 is aligned with the center of the rotating support seat 72;

[0076] Adjust the height of the annular butt joint assembly 11, cover the upper table plate 71, so that one of the first cover body 111 and the second cover body 112 of the annular butt joint assembly 11 at least partially abuts the lower table plate 73, and the other at least partially abuts the upper table plate 71 and rotates with the upper table plate 71.

[0077] Compared with the prior art, the rotating table and the manufacturing method thereof have the following advantages:

[0078] 1.The rotary table of the present application comprises an upper table plate, a lower table plate, a rotary support seat and a power supply connecting piece arranged between the upper table plate and the lower table plate, the upper table plate is rotatable relative to the lower table plate, the power supply connecting piece is sleeved on the rotary support seat and simultaneously abuts against the upper and lower table plates. The power supply connecting piece comprises a ring-shaped butt joint assembly, the ring-shaped butt joint assembly comprises a first cover body and a second cover body which are rotatably connected, and a ring-shaped conductive track and a conductive contact piece are respectively arranged in the first cover body and the second cover body. When the first cover body and the second cover body rotate relative to each other, the conductive contact piece moves along the conductive track. In use, at least part of one of the first cover body and the second cover body abuts against the lower table plate, and at least part of the other abuts against the upper table plate and rotates with the upper table plate. When the upper table plate rotates, the cover body abutting against the upper table plate is driven to rotate, so that the first cover body and the second cover body also rotate relative to each other, and the conductive contact piece moves along the conductive track to keep the conductive contact piece electrically connected with the conductive track at all times. In the specific embodiment, at least part of the first cover body abuts against the lower table plate, and at least part of the second cover body abuts against the upper table plate. One of the conductive contact piece and the conductive track is electrically connected with an electric appliance to be used, and the other is electrically connected with an external power supply, so that the electric appliance placed on the upper table plate can be conveniently used. Compared with the conventional use mode in which the wires connected between the electric appliance and the external power supply are wound with each other or wound on the rotary table to cause an electrical hazard, the power supply connecting piece optimizes the circuit design, so that the electric appliance is always electrically connected with the first cover body abutting against the upper table plate during the rotation of the upper table plate, the first cover body rotates relative to the second cover body and is always electrically connected with the second cover body, and the second cover body is electrically connected with the external power supply, that is, the electric connection between the electric appliance and the external power supply is realized through the ring-shaped butt joint assembly, and the wires will not be wound with each other or wound on the rotary table, thereby realizing the function of conveniently using the electric appliance on the rotary table.

[0079] 2.One of the surface of the first cover body away from the second cover body and the surface of the second cover body away from the first cover body is provided with an elastic adjusting piece, and the other is provided with a soft rubber. The elastic adjusting piece and the soft rubber can improve the stability of the cooperation between the power supply connecting piece and the rotary table.

[0080] 3.The number of the conductive tracks is set to two or three, and at least one conductive contact piece abuts against each conductive track, so that the power supply connecting piece can be connected with a three-hole socket or a two-hole socket to facilitate the cooperation between the power supply connecting piece and the electric appliance with a three-pin plug or a two-pin plug.

[0081] 4.The conductive tracks are arranged in concentric rings and are insulated from each other, so that the conductive contact piece can always abut against the ring-shaped conductive track during the rotation of the first cover body relative to the second cover body.

[0082] 5. The power connector of the present application further comprises a plug and a socket, the plug and the socket are connected with the conductive track and the conductive contact through wires respectively. During the rotation of the second cover relative to the first cover, the conductive contact moves on the conductive track, so that the plug and the socket always maintain electrical connection, realizing the function of convenient use of electrical appliances on the rotating table.

[0083] 6. The annular docking assembly of the present application comprises a center through hole, the diameter of the center through hole is slightly larger than the diameter of the rotating support base. The side surface of the first cover and the second cover towards the center through hole is provided with a support foam. The support foam is beneficial to prevent the side surface of the annular docking assembly towards the center through hole from directly rubbing against the rotating support base of the rotating table during the rotation of the first cover relative to the second cover, protecting the annular docking assembly and improving the service life of the power connector. The support foam can also dynamically adjust the position of the annular docking assembly and the rotating support base of the rotating table. Specifically, the position of the center of the annular docking assembly is adjusted to coincide with the position of the center of the rotating support base, facilitating the cooperation of the power connector with rotating tables of multiple specifications.

[0084] 7. The conductive contact of the present application comprises a bracket and a roller, the bracket is provided with a mounting groove, and the roller is rotatably connected in the mounting groove and partially exposed from the mounting groove to contact the conductive track. The roller can make the conductive contact roll on the conductive track, which can reduce the friction between the conductive contact and the conductive track compared with sliding, thereby prolonging the service life of the power connector.

[0085] 8. Two rollers are arranged in the mounting groove at intervals, and the rollers on the same conductive contact abut against the same conductive track. Compared with arranging a single roller, this arrangement is beneficial to improve the stability of the abutment between the conductive contact and the conductive track, thereby improving the stability of the power connector in use.

[0086] 9. The rim of the roller is formed with an arc-shaped notch, the cross section of the conductive track is circular, the diameter of the arc-shaped notch is the same as the diameter of the cross section of the conductive track, and the conductive track abuts against the arc-shaped notch and is attached to the inner wall of the arc-shaped notch. On the one hand, the conductive contact will not be deviated in the direction perpendicular to the rotation direction of the conductive contact under the action of centrifugal force during the rotation of the conductive contact on the conductive track, and on the other hand, the arc-shaped notch can increase the contact area between the conductive contact and the conductive track, thereby improving the stability of the power connector.

[0087] 10. The present application further provides a manufacturing method of a rotating table, which has the same beneficial effects as the above-mentioned rotating table and will not be described here.

[0088] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement within the principle of the present application shall be included in the protection scope of the present application.
