[0039] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the interlocking device created by the present invention. The interlocking device created by the present invention is not limited to the description of the following embodiments.

[0040] like Figure 1-3 As shown, the track socket of this embodiment includes a track (not shown in the figure) and at least one adapter, the adapter including an adapter body, the adapter body including a rotating part 2 and a fixed disk 3 rotatably connected, the rotating part 2 and the fixed disk 3 are coaxially arranged, the rotating part 2 is rotatably arranged on the fixed disk 3, and can rotate relative to the fixed disk 3, the fixed disk 3 is provided with a connecting part 30 for connecting the adapter body to the track on the side facing away from the rotating part 2, the connecting part 30 is a flat protrusion extending in the direction away from the rotating part 2, and its shape is adapted to the slide groove on the track, a conductive part 4 is provided in the rotating part 2, and the conductive part 4 is provided with an end of a conductive pin 420 extending into the connecting part 30 and partially able to rotate out of the rotating part 2 with the rotating part 2 for electrical connection with the track, when the rotating part 2 rotates, the conductive pin 420 rotates out of the connecting part 30 with the rotating part 2 to connect with the track or rotates back to the connecting part 30 with the rotating part 2 to disconnect from the track.

[0041] The improvement of this embodiment is that the conductive part 4 includes a wiring terminal 41 and a contact piece 42 that are electrically connected to each other. The wiring terminal 41 is fixedly arranged in the rotating part 2 and is used to connect to the wire of an external electrical appliance. One end of the contact piece 42 is connected to the wiring terminal 41, and the other end extends into the connecting part 30 as the conductive pin 420, which is connected or disconnected with the track as the rotating part 2 rotates. Specifically, when the rotating part 2 rotates in one direction (such as clockwise) relative to the fixed disk 3, the conductive pin 420 extends from the connecting part 30 and is electrically connected to the track, and the circuit is now conductive; when the rotating part 2 rotates in the other direction relative to the fixed disk 3, the conductive pin 420 is separated from the track and stored in the connecting part 30. At this time, the adapter can be inserted into or removed from the track. The rotating part 2 is also provided with a wire threading hole 20. The wires of the external electrical appliance pass through the wire threading hole 20 and are connected to the terminal 41. When in use, the wires of the external electrical appliance extend into the rotating part 2 through the wire threading hole 20 and are detachably connected to the terminal 41. At this time, the connecting part 30 of the adapter is inserted into the slide groove on the track, and the rotating part 2 is rotated to extend the conductive pin 420 and electrically connect to the track to complete the power supply. Preferably, the wire threading hole 20 is provided on the side wall of the rotating part 2, and its position corresponds to the terminal 41. When the external electrical appliance is connected to the adapter, it is more beautiful and easy to operate.

[0042] In the detachable track socket adapter of this embodiment, the wires of the external electrical appliance are directly extended into the adapter body and connected to the terminal 41, and then the power is directly obtained through the adapter and the track, replacing the commonly used method of obtaining power through the middle of the adapter between the electrical plug and the track. This prevents the electrical appliance from being too high after stacking, is more beautiful, and at the same time avoids the situation where the plug falls off due to touching or dragging, affecting the use of the electrical appliance.

[0043] like Figure 3-5 As shown, as an embodiment of the rotating part 2, it includes an upper cover 21 and a lower cover 22 that are fixedly connected. A space for accommodating other accessories such as the conductive part 4 is formed between the upper cover 21 and the lower cover 22. The lower cover 22 is provided with at least two mounting grooves 220 on the side facing the upper cover 21. The wiring terminals 41 are fixedly installed in the mounting grooves 220. In this embodiment, there are three mounting grooves 220 and three corresponding wiring terminals 41, which correspond to the L-pole wiring terminal, the N-pole wiring terminal and the grounding wiring terminal, respectively. The mounting grooves 220 for the L-pole and N-pole wiring terminals are symmetrically arranged on both sides of the mounting groove 220 for the grounding wiring terminal. It can be understood that, depending on the different external electrical appliances connected, they can be omitted or not connected to the grounding wiring terminal 41 when necessary;

[0044] Furthermore, a sleeve shaft 221 is provided at the axis center position on the other side of the lower cover 22 ( Figure 1), the sleeve shaft 221 is located in the connecting portion 30, and the two contact pieces 42 are mounted on the sleeve shaft 221. When the rotating portion 2 rotates, the sleeve shaft 221 drives the two contact pieces 42 to rotate together. Preferably, the sleeve shaft 221 is a cylinder extending along the axial direction of the adapter body, with a height level with the connecting portion 30. Two wing-shaped insulating plates radially extend from both sides of the end thereof. The two contact pieces 42 are spaced apart on both sides of the sleeve shaft 221, and one end of the two contact pieces 42 is bent in opposite directions along the radial direction of the sleeve shaft 221 to serve as a conductive pin 420. The conductive pin 420 partially extends from the insulating plate for connection with the track;

[0045] Preferably, a through hollow interlayer is formed between the bottom surface of the lower cover 22 and the interior of the sleeve shaft 221, and the other end of the contact piece 42 is arranged in the interlayer of the bottom surface of the lower cover 22, and partially extends out of the bottom surface of the lower cover 22 to be connected to the terminal 41. That is to say, the main part of the contact piece 42 is arranged inside the lower cover 22 so that the two are formed as one piece. In this way, the sleeve shaft 221, the lower cover 22 and the two contact pieces 42 are designed to be formed as one piece. The contact piece 42 is injection molded as a whole in the mold when the sleeve shaft 221 and the lower cover 22 are injection molded, so that the process of the contact piece 42 rotating with the rotating part 2 is more reliable, and the conductive pin 420 is prevented from being damaged during the process of connecting and disconnecting with the track.

[0046] Further, such as Figure 1 、 9 As shown, the conductive part 4 also includes a grounding shaft 45, which is arranged on the sleeve shaft 221 and has at least one contact end located at the axis center of one end of the sleeve shaft 221. In this embodiment, the contact end of the grounding shaft 45 extends out of the adapter body along the axial direction of the sleeve shaft 221, and the contact end extends to the end axis center position of the sleeve shaft 221, and the other end extends into the rotating part 2 and is connected to the conductive contact 411 of the grounding terminal 41.

[0047] The two contact pieces 42 are respectively an L-pole contact piece and an N-pole contact piece. The L-pole connection terminal, the N-pole connection terminal and the ground connection terminal are respectively connected to the L-pole contact piece, the N-pole contact piece and the ground shaft 45 .

[0048] Furthermore, the sleeve 221 has grooves at both axial ends. The grounding shaft 45 is mounted on the outside of the sleeve 221. The ends of the grounding shaft 45 are bent into the grooves at the ends of the sleeve 221 to serve as contact ends. These contact ends are positioned at the axis of the sleeve 221, with one end within the rotating portion 2 resting on the conductive contact 411 extending from the grounding electrode terminal 41 toward the lower cover 22. This means that the grounding shaft 45 has a roughly U-shaped structure, with the sidewalls of the U-shaped structure positioned at both ends of the sleeve 221. In this embodiment, the two contact pieces 42 are integrally formed within the sleeve 221, while the grounding shaft 45 is positioned outside the sleeve 221. The grounding shaft 45 can be optionally positioned as needed. Of course, the grounding shaft 45 can also be positioned within the sleeve 221, employing a linear structure that extends along the axis of the sleeve 221 toward both ends of the sleeve 221, connecting to the terminal and / or rail.

[0049] like Figure 8 The specific structure of the terminal block 41 shown includes a conductive contact 411, a fixing screw and a wire fixing portion 410. The conductive contact 411 and the fixing screw 412 are correspondingly arranged on both sides of the fixing portion 410 for clamping the wire in the fixing portion 410. For ease of operation, the fixing screw 412 is preferably arranged on the side of the fixing portion 410 facing the upper cover 21, and the conductive contact 411 is arranged on the side facing the lower cover 22. When the wire extends into the fixing portion 410, the fixing screw 412 is tightened until it contacts the conductive contact 411. At this time, the fixing screw 412 can Press the wire onto the conductive contact 411, loosen the wire fixing screw 412 to separate it from the conductive contact 411, and then take the wire out of the wire fixing portion 410 for replacement. One end of the conductive contact 411 is located in the wire fixing portion 410 and contacts the wire, and the other end extends out of the wire fixing portion 410 and extends toward the lower cover 22. That is, the conductive contact 411 includes two contact surfaces. The contact surface located in the wire fixing portion 410 is used to connect with the wire, and the contact surface extending toward the lower cover 22 is used to connect with the contact piece 42 or the grounding shaft 45 and then electrically connect with the track to achieve circuit conduction.

[0050] In the detachable track socket adapter of this embodiment, the terminal 41 fixes the wire in the wire fixing portion 410 through the wire fixing screw 412 and the conductive contact 411. The structure is simple and not easy to be damaged. The wire can be fixed or removed by tightening or loosening the wire fixing screw 412, which is simple and convenient to operate and replace.

[0051] Preferably, the conductive contact piece 411 of the wiring terminal 41 corresponding to the L pole and the N pole is extended to the lower cover 22 at one end and has a connection hole 43. The contact piece 42 is provided with a connecting shaft 44, and the connecting shaft 44 is plugged into the connection hole 43. Since the relative positions of the lower cover 22, the wiring terminal 41 and the contact piece 42 do not change during the rotation process, the plug-in method is adopted to further ensure the stability of the connection between the wiring terminal 41 and the contact piece 42.

[0052] like Figure 2-3 As shown in , and 7, a pressure plate 5 is also provided on the mounting groove 220, and the wiring terminal 41 is installed in the space enclosed by the pressure plate 5 and the mounting groove 220 to prevent the wiring terminal 41 from sliding out of the mounting groove 220. The pressure plate 5 and the mounting groove 220 are respectively provided with mutually cooperating connecting parts, and the two are fixed when the pressure plate 5 is sleeved on the mounting groove 220. Specifically, the connecting part includes a buckle 53 and a slot 52, and the buckle 53 is arranged on the outside of the mounting groove 220, and the slot 52 is arranged at a corresponding position on the inner wall of the pressure plate 5. When the pressure plate 5 is sleeved on the mounting groove 220, the buckle 53 and the slot 52 are snap-fitted to fix the pressure plate 5 on the mounting groove 220 and then fix the wiring terminal 41 in the mounting groove 220. It can be understood that the connecting part can adopt other existing technical methods, such as welding or threaded connection. Only the preferred solution is given here.

[0053] Furthermore, the pressing plate 5 is provided with a screw hole 50 and a wire entry hole 51. When the pressing plate 5 is sleeved on the mounting groove 220, one end of the nut of the wire fixing screw 412 extends into the screw hole 50. The wire fixing screw 412 of the terminal block 41 can be operated through the screw hole 50, and the wire is inserted into the wire fixing portion 410 through the wire entry hole 51. In order to facilitate operation, the screw hole 50 and the wire fixing screw 412 are correspondingly opened at the upper end of the pressing plate 5, and the wire entry hole 51 is opened between the wire fixing portion 410 and the threading hole 20.

[0054] like Figure 2-3As shown, this embodiment also provides a wire pressing portion 6 for further fixing the wire to the adapter body, the wire pressing portion 6 includes a fixed end and a free end, the fixed end and the free end are movably connected, the wire passes through the gap between the fixed end and the free end and extends to the wiring terminal 41, as the free end approaches the fixed end, the wire is clamped in the gap between the two, specifically, the fixed end is a boss 61 arranged on the lower cover 22, the boss 61 is provided with a wire pressing screw column 610, the free end includes a wire pressing clamp 62 and a wire pressing screw 620, the wire pressing screw 620 passes through the wire pressing clamp 62 and extends into the wire pressing screw column 610, the boss 61 and the wire pressing clamp 62 are movably connected by the wire pressing screw 620, leaving a gap between the two, and the gap is rotated as the wire pressing screw 620 rotates. It can be tightened or loosened to shrink or expand, and can adapt to wires of different sizes and can adjust the clamping force. Preferably, there are two wire-pressing screw columns 610 and wire-pressing screws 620. The two wire-pressing screw columns 610 are respectively arranged at the two ends of the boss 61, and the two wire-pressing screws 620 pass through the two ends of the wire-pressing clamp 62 and extend into the wire-pressing screw columns 610. The middle part of the boss 61 is recessed inward to form a circular arc-shaped wire-pressing groove 611. In this way, the part of the wire extending into the adapter body is further fixed by setting the wire-pressing clamp 62, so that the movement of the external wire will not affect the connection between the internal wire and the terminal 41, and the connection between the wire-pressing clamp 62 and the two ends of the boss 61 is more stable. The circular arc-shaped wire-pressing groove 611 ensures the clamping effect while avoiding damage to the insulation layer of the wire.

[0055] The rotating part 2 rotates between a first position and a second position. When the rotating part 2 rotates to the first position, the conductive pin 420 of the contact piece 42 extends from the connecting part 30 and is connected to the track. At this time, the angle between the conductive pin 420 and the connecting part 30 is 90°. When the rotating part 2 rotates to the second position, the conductive pin 420 of the contact piece 42 is disconnected from the track and stored in the connecting part 30. At this time, the adapter can be inserted into or removed from the track.

[0056] Further, such as Figure 2 、 5 As shown in Figures 6 and 7, the lower cover 22 of the rotating part 2 is provided with a concentric annular track groove 222, and the rotating part 2 rotates along the track groove 222. The track groove 222 is preferably arranged near the outer edge of the lower cover 22 to avoid structures such as the mounting groove 220. The fixed plate 3 is integrally formed with an annular rotating connector 31 on the side facing away from the connecting part 30. The rotating connector 31 corresponds to the track groove 222 and extends into the track groove 222. The rotating part 2 rotates along the track groove 222 relative to the rotating connector 31 between a first position and a second position.

[0057] Furthermore, the trajectory groove 222 and the rotating connector 31 are respectively provided with a limiting structure 7 that cooperates with each other. When the rotating part 2 rotates to the first position or the second position, the limiting structure 7 prevents the rotating part 2 from further rotating. The limiting structure 7 includes a first blocking part 71 and a second blocking part 72. The first blocking part 71 is integrally formed with the lower cover 22 and is arranged in the trajectory groove 22. The second blocking part 72 is a protrusion integrally formed on the top of the rotating connector 31. Both ends of the first blocking part 71 and the second blocking part 72 are abutment parts. When the rotating part 2 is rotated into place, the abutment parts abut against each other to prevent the rotating part 2 from further rotating.

[0058] In this embodiment, the first blocking portion 71 spans the track groove 222 and is rotationally symmetrically arranged on both sides of the lower cover 22. Its bottom surface is slightly higher than the top of the rotating connector 31. One end of the first blocking portion 71 is an arc-shaped depression, and the other end is a square depression. Correspondingly, the two ends of the second blocking portion 72 are an arc-shaped protrusion and a square protrusion respectively. When the two are in contact, the protrusion of the second blocking portion 72 is just embedded in the depression on the first blocking portion 71.

[0059] When the rotating part 2 rotates toward the first position relative to the fixed disk 3, the first blocking part 71 moves along the track groove 222 toward one end of the square protrusion of the second blocking part 72. When reaching the first position, the protrusion and the recess are engaged, and the second blocking part 72 abuts against the first blocking part 71. At this time, the rotating part 2 cannot continue to rotate toward the first position; similarly, when the rotating part 2 rotates to the second position, the arc-shaped protrusion and the recess are engaged with each other, preventing the rotating part 2 from continuing to rotate toward the second position.

[0060] It can be understood that the first blocking portion 71 and the second blocking portion 72 are not limited to the structure described in this embodiment. It is only necessary that the two abut against each other when the rotating part 2 rotates to the first position and / or the second position without affecting the rotation process. For example, the protrusion and the recess are omitted so that the two abut against each other in a plane.

[0061] The detachable track socket adapter of this embodiment adopts the second blocking portion 72 and the first blocking portion 71 integrally formed with the rotating portion 2 and the fixed plate 3 to limit the rotation position. During the rotation process, the limiting structures 7 do not interfere with each other and only abut against each other when they are rotated into place, which does not affect the rotation process and the limiting function is reliable.

[0062] like Figure 1-3When the second blocking portion 72 abuts the first blocking portion 71, the locking structure 8 locks the relative position of the rotating portion 2 and the fixed disk 3. The locking structure 8 includes a locking member 80, a return spring 81 and a limiting protrusion 822 provided on the second blocking portion 72. The locking member 80 includes an operating end 820 and a locking end 821. The locking end 821 extends toward the track groove 222 and locks with the limiting protrusion 822. The operating end 820 extends out of the adapter body for operating the locking end 821 to release the locking from the limiting protrusion 822. The return spring 81 is connected between the lower cover 22 and the locking member 80. When the rotating portion 2 is rotated to the first position or the second position, the locking end 821 abuts and locks with the limiting protrusion 822. At this time, pressing the operating end 820 causes the locking member 80 to move toward the inside of the adapter body, compressing the return spring 81, and the locking end 821 is separated from the limiting protrusion 822 to release the lock.

[0063] Preferably, a limiting piece 223 is provided on the outside of the second blocking portion 72 located at the first position, and the limiting piece 223 is integrally formed with the lower cover 22, and the locking piece 80 is provided on the limiting piece 223, that is, when the conductive pin 420 extends out of the connecting portion 30 and is connected to the track, the first blocking portion 71 and the second blocking portion 72 abut against each other in the first position, preventing the rotating portion 2 from continuing to rotate toward the first position, and the locking end 821 abuts against the limiting protrusion 822, preventing the rotating portion 2 from rotating toward the second position. In this way, through the cooperation of the locking structure 8 and the limiting structure 7, the rotating portion 2 is fixed at the position where the adapter is connected to the track, avoiding the impact on use due to accidental touch or incomplete rotation, thereby ensuring the safety of the adapter during use.

[0064] Furthermore, the locking end 821 has an inclined surface toward the first position and a flat surface on the other side; the limiting protrusion 822 has an inclined surface toward the second position and a flat surface on the other side. When the rotating part 2 rotates from the second position to the first position relative to the fixed disk 3, the locking end 821 moves in the direction of the limiting protrusion. Before entering the locking position, the two inclined surfaces contact to cause the locking member 80 to move toward the inside of the adapter body, while compressing the reset spring 81. When the locking position (first position) is reached, the reset spring 81 is released, and the locking end 821 abuts against the flat surface of the limiting protrusion, cooperating with the limiting structure 7 to lock the relative position of the rotating part 2 and the fixed disk 3. At this time, the locking member 80 pops out under the action of the reset spring 81, giving the user a prompt.

[0065] like Figure 2-4As shown, there are assembly screw columns 90 between the upper cover 21 and the lower cover 22. The assembly screws 91 are screwed into the assembly screw columns 90 to fix the upper cover 21 and the lower cover 22 together. When in use, the upper cover 21 can be directly rotated to drive the lower cover 22 to rotate together. The upper cover 21, the lower cover 22 and the fixed plate 3 are surrounded to form a hollow shell 1. Preferably, as shown in FIG. Figure 5-6 As shown, in order to prevent the fixed plate 3 from falling off from the lower cover 22, an insert 32 is further provided between the lower cover 22 and the fixed plate 3. One end of the insert 32 is fixedly connected to the lower cover 22, and the other end is slidably connected to the fixed plate 3. Specifically, connecting columns are provided on the edges of both sides of the lower cover 22. Holes corresponding to the connecting columns are provided on the insert 32. The end of the insert 32 with the hole is plugged into the lower cover 22. An insert slot 33 is provided on the outer wall of the fixed plate 3. The other end of the insert 32 is bent toward the outer wall of the fixed plate 3 and extends into the insert slot 33. When the lower cover 22 is rotated, the insert 32 slides in the insert slot 33 with the lower cover 22, and cooperates with the insert slot 33 to prevent axial displacement between the lower cover 22 and the fixed plate 3; of course, under the condition that the rotating part 2 and the fixed plate 3 are rotatably connected, the structure and rotation method of the shell 1 can also be achieved in other ways, such as adding a control member for driving the lower cover 22 to rotate or swapping the positions of the connecting part 30 and the conductive part 4, and the fixed plate 3 rotates to drive the conductive pin 420 to extend and connect with the track, which can achieve the corresponding effect.
