[0046] In order to facilitate the understanding of the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. The preferred embodiments of the present application are shown in the drawings. However, the present application can be realized in many different forms and is not limited to the embodiments described in the specification. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0047] It should be noted that, unless otherwise defined, all technical and scientific terms used in the specification are the same as those commonly understood by those skilled in the art to which the present application belongs. The terms used in the specification of the present application are only for the purpose of describing the specific embodiments and are not intended to limit the present application. The term "and / or" used in the specification includes any and all combinations of one or more related listed items.

[0048] The existing track system consists of a track and an adapter unit which is mounted on the track by a "key" or "contact arm" system. The disadvantage of this system is that it not only makes the entire track system significantly thicker, but also the protruding adapter becomes an additional obstacle during normal use. When not in use, the adapter protrusion still provides an additional obstacle and requires additional storage space. The adapter protrusion also exacerbates the mechanical weakness of the "key" or "contact arm" as it provides an additional point of applied torque, increasing the point of failure.

[0049] Figure 1 An embodiment of the power distribution device of the present application is shown, comprising a track 1 and an adapter 2 mounted within the track 1 for taking power, the upper end face of the adapter 2 being flush with the upper end face of the track 1.

[0050] The track 1 has a containing space, and the adapter 2 is installed in the containing space. The depth of the containing space is equal to, slightly greater than, or slightly less than the thickness of the adapter 2. In this way, the upper end surface of the adapter 2 can be flush or close to flush with the upper end surface of the track 1.

[0051] The upper end surface of the adapter 2 is flush with the upper end surface of the track 1, which can avoid the adapter 2 protruding from the track 1 and reduce the occupied space of the adapter 2. In addition, it can avoid accidental contact with the adapter 2 and improve the safety of the adapter 2. It also reduces the failure points of the adapter 2.

[0052] The adapter 2 includes a strong current adapter, a weak current adapter, and / or a data transmission adapter.

[0053] The strong current adapter includes a Chinese socket, a British standard socket, a German standard socket, a French socket, an Italian socket, a US socket, etc.

[0054] The weak current adapter includes a USB charging adapter, a wireless charging adapter, a Bluetooth speaker adapter, etc.

[0055] The data transmission adapter includes an HDMI adapter, a USB data transmission adapter, a network data transmission adapter, a control switch adapter, etc.

[0056] As shown in Figure 1 and Figure 2 , the upper side of the track 1 has an opening, and the upper side of the track 1 is provided with a sealing structure 4 that seals the opening.

[0057] The track 1 is sealed by the sealing structure 4 to prevent dust from entering the containing space in the track 1.

[0058] The sealing structure 4 has two use states, including an open state and a closed state. In the open state, the adapter 2 is exposed for easy power supply. In the closed state, the sealing structure 4 is closed to seal the opening and prevent dust from entering the containing space in the track 1.

[0059] Multiple adapters 2 can be arranged in the track 1, and the openings at the corresponding positions of the adapters 2 are connection ports 11. The openings can be divided into multiple connection ports 11 by the adapters 2.

[0060] In terms of size, the size of the sealing structure 4 is adapted to the size of the opening or at least one of the connection ports 11.

[0061] When the size of the sealing structure 4 is adapted to the size of the opening, the sealing structure 4 can seal the entire opening of the track 1. When the sealing structure 4 is opened, the opening of the track 1 is opened, and all the adapters 2 can be exposed for power supply. When the sealing structure 4 is closed, the opening of the track 1 is sealed, preventing dust from entering. However, this sealing method can only open or seal the opening as a whole. When multiple adapters 2 are installed in the track 1 and only one adapter 2 is used, dust can easily enter the track 1 from the positions of the other adapters 2, which is less secure.

[0062] Preferably, the size of the sealing structure 4 is adapted to the size of the connecting port 11. Taking one connecting port 11 as an example, one sealing structure 4 is provided corresponding to the connecting port 11, and one sealing structure 4 can seal one connecting port 11. When one sealing structure 4 is opened, the adapter 2 at the corresponding position can be exposed for power supply, and the sealing structures 4 at other positions can be opened or closed. Thus, the opening or closing of the corresponding connecting port 11 can be controlled by the sealing structure 4. Thus, when one adapter 2 is used, dust can be prevented from entering from the connecting port 11 corresponding to the other adapter 2.

[0063] In terms of structure, the sealing structure 4 can be a whole structure or a split structure. When the sealing structure 4 is a whole structure, the size of the sealing structure 4 is adapted to the size of the opening or the connecting port 11, and the opening or the connecting port 11 is sealed. When the sealing structure 4 is a split structure, the sealing structure 4 is composed of multiple sealing sub-structures, and the size of the multiple sealing sub-structures combined together is adapted to the size of the opening or the connecting port 11, and the opening or the connecting port 11 is sealed.

[0064] The track 1 includes a bottom plate, and first and second side plates 12 and 13 extending upward from the front and rear sides of the bottom plate.

[0065] In terms of connection, the connection between the sealing structure 4 and the track 1 includes hinging, clamping, or lapping, etc.

[0066] The hinging between the sealing structure 4 and the track 1 can be achieved in multiple ways.

[0067] When the sealing structure 4 is a whole structure, the hinging side of the sealing structure 4 is hinged to the first side plate 12 of the track 1, and the free side of the sealing structure 4 is attached to the second side plate 13 of the track 1 to seal the opening or the connecting port 11. Or the hinging side of the sealing structure 4 is hinged between one end of the first and second side plates 12 and 13, and the free side of the sealing structure 4 is attached between the other end of the first and second side plates 12 and 13.

[0068] When the sealing structure 4 is a split structure, for example, as shown in FIG. 6, the sealing structure 4 is composed of multiple sealing sub-structures 4a, 4b, and 4c. The hinging side of the sealing sub-structure 4a is hinged to the first side plate 12 of the track 1, and the free side of the sealing sub-structure 4a is attached to the second side plate 13 of the track 1 to seal the opening or the connecting port 11. The hinging side of the sealing sub-structure 4b is hinged between one end of the first and second side plates 12 and 13, and the free side of the sealing sub-structure 4b is attached between the other end of the first and second side plates 12 and 13. The hinging side of the sealing sub-structure 4c is hinged to the first side plate 12 of the track 1, and the free side of the sealing sub-structure 4c is attached to the second side plate 13 of the track 1 to seal the opening or the connecting port 11. Figure 3As shown in the figure, when the sealing structure 4 comprises the first sealing substructure 401 and the second sealing substructure 402, the hinged side of the first sealing substructure 401 is hinged to the first side plate 12 of the track 1, the hinged side of the second sealing substructure 402 is hinged to the second side plate 13 of the track 1, and the free side of the first sealing substructure 401 is attached to the free side of the second sealing substructure 402 to seal the opening or the connecting port 11. Alternatively, as shown in the figure, Figure 4 As shown in the figure, the hinged side of the first sealing substructure 401 and the hinged side of the second sealing substructure 402 are both hinged between the first side plate 12 and the second side plate 13 of the track 1, and the free side of the first sealing substructure 401 is attached to the free side of the second sealing substructure 402 to seal the opening or the connecting port 11. Alternatively, as shown in the figure, Figure 5 As shown in the figure, the hinged side of the first sealing substructure 401 is hinged to the first side plate 12 of the track 1, the free side of the first sealing substructure 401 is hinged to the hinged side of the second sealing substructure 402, and the free side of the second sealing substructure 402 is attached to the second side plate 13 of the track 1 to seal the opening or the connecting port 11.

[0069] When hinged, the position of the sealing structure 4 can be determined by the transition fit between the hinged shaft and the sealing structure 4, and the transition fit between the hinged shaft and the track 1. The transition fit tolerance is preferably H6 / k5. When there is no external force, the friction at the fit position can prevent the sealing structure 4 from rotating relative to the track 1. When there is a certain external force, the sealing structure 4 can be rotated relative to the track 1 by the external force. A torsional spring 2832 can also be used to apply an external force to the sealing structure 4 to cover the sealing structure 4 at the opening or the connecting port 11 of the track 1. For example, when one side of the sealing structure 4 is hinged to the front end of the first side plate 12, one end of the torsional spring 2832 abuts against the inner wall of the first side plate 12 of the track 1, and the other end of the torsional spring 2832 abuts against the inner wall of the sealing structure 4. In this way, the sealing structure 4 can be rotated about the hinged shaft from bottom to top, and when the sealing structure 4 is perpendicular to the first side plate 12, the sealing structure 4 is limited to prevent excessive rotation to the upper side of the opening. When the sealing structure 4 is limited, a baffle can be extended downward from the front end of the second side plate 13 to limit the sealing structure 4.

[0070] When connected by hinging, as shown in the figure, Figure 6 and Figure 7 As shown in the figure, the track 1 comprises the first side plate 12 and the second side plate 13, and when the sealing structure 4 is hinged to the track 1, the sealing structure 4 comprises the first sealing plate 41 and the second sealing plate 42 hinged to the first side plate 12 and the second side plate 13, and the fixing assembly 43 for fixing the first sealing plate 41 and the second sealing plate 42.

[0071] The first sealing plate 41 and the second sealing plate 42 are hingedly connected between the first side plate 12 and the second side plate 13 of the adapter 2. The lower surface of the first sealing plate 41 and the second sealing plate 42 at the adjacent position is provided with a support plate 431 supporting a fixing assembly 43, and the fixing assembly 43 is arranged on the support plate 431.

[0072] When the sealing structure 4 is closed, the fixing assembly 43 fixes the sealing structure 4 in the closed state.

[0073] The fixing assembly 43 comprises a first fixing sealing member 432, a second fixing sealing member 433, a first clamping block 4321 clamping the first fixing sealing member 432 and the second fixing sealing member 433, the first fixing sealing member 432 is fixedly connected with the first sealing plate 41, the second fixing sealing member 433 is fixedly connected with the second sealing plate 42, the first clamping block 4321 is connected with the first fixing member 271 and the second fixing member 271, and the first fixing member 271 and the second fixing member 271 lock the first sealing plate 41 and the second sealing plate 42.

[0074] The first fixing sealing member 432 is provided with a stop block 4326, the stop block 4326 is provided with a stop block groove 43261 adjacent to the first clamping block 4321, and the fixing assembly 43 further comprises a first torsion spring 4322 providing a force to the first clamping block 4321, the first torsion spring 4322 presses the first clamping block 4321 into the stop block groove 43261, and the first sealing plate 41 and the second sealing plate 42 are locked.

[0075] The first fixing sealing member 432 is semicircular, the first fixing sealing member 432 has a groove 4323, a fixing rod 4324 is arranged in the groove 4323 adjacent to the center of the circle, a clamping table 4325 is arranged in the groove 4323 on one side of the fixing rod 4324, and a stop block 4326 is arranged in the groove 4323 on the other side of the fixing rod 4324. The clamping table 4325 and the inner wall of the first fixing sealing member 432 have a clamping portion 43251, and the stop block 4326 has a stop block groove 43261 adjacent to the clamping portion 43251. The second fixing sealing member 433 has the same structure as the first fixing sealing member 432, except that the positions of the clamping portion 43251 and the stop block 4326 of the first fixing sealing member 432 are opposite to those of the clamping portion 43251 and the stop block 4326 of the second fixing sealing member 433. Thus, the first clamping block 4321 is clamped at the clamping portion 43251 of the first fixing sealing member 432 and the stop block 4326 of the second fixing sealing member 433. The first torsion spring 4322 is sleeved on the fixing rod 4324 of the first fixing sealing member 432, one end of the first torsion spring 4322 abuts against the clamping table 4325 of the first fixing sealing member 432, and the other end abuts against the end of the first clamping block 4321 away from the second fixing sealing member 433. Similarly, the first fixing sealing member 432 and the first fixing sealing member 432 are arranged in the same way, and will not be repeated.

[0076] In the locking mode, the first clamping block 4321 is pressed into the block groove 43261 of the block 4326 by the force of the first torsion spring 4322 in the first fixed seal 432, and when the first clamping block 4321 enters the block groove 43261, the first clamping block 4321 is blocked on the lower side of the first sealing plate 41 and the second sealing plate 42, so that the first sealing plate 41 and the second sealing plate 42 can be locked by the first clamping block 4321, and cannot be opened without external force.

[0077] The unlocking mode can be that a fixed groove is arranged at the joint of the first sealing plate 41 and the second sealing plate 42, and a fixed hole 4327 is formed when the fixed groove of the first sealing plate 41 and the fixed groove of the second sealing plate 42 are enclosed. The bottom of the adapter 2 is provided with a protruding part 2321 matched with the fixed hole 4327. When the protruding part 2321 is pressed into the fixed hole 4327, the first clamping block 4321 is squeezed out of the block groove 43261, and the unlocking is completed, so that the first sealing plate 41 and the second sealing plate 42 can be opened.

[0078] The unlocking mode can also be that a first magnetic part 4328 protruding the first clamping block 4321 is arranged on the first clamping block 4321, and a second magnetic part matched with the first magnetic part 4328 is arranged on the bottom of the adapter 2. The second magnetic part is attracted to the first magnetic part 4328 under the action of magnetic force, the adapter 2 is rotated to make the second magnetic part rotate, the rotation of the second magnetic part drives the rotation of the first magnetic part 4328, the first magnetic part 4328 makes the first clamping block 4321 rotate, and the first clamping block 4321 slides out of the block groove 43261, the unlocking is completed, and the first sealing plate 41 and the second sealing plate 42 can be opened.

[0079] The second fixed seal 433 has the same action as the first fixed seal 432, and will not be described again.

[0080] The sealing structure 4 and the track 1 can be connected in various ways. When the sealing structure 4 is an integral structure, a clamping groove can be arranged at the rear of the upper end surface of the first side plate 12 and the front of the upper end surface of the second side plate 13, and the two sides of the sealing structure 4 are clamped between the clamping grooves to seal the opening or the connecting port 11.

[0081] The clamping grooves can also be arranged at the middle of the upper end surface of the first side plate 12 and the middle of the upper end surface of the second side plate 13, and the two ends of the sealing structure 4 extend downward to form clamping blocks matched with the clamping grooves, and the clamping blocks are clamped in the clamping grooves to seal the opening or the connecting port 11.

[0082] Preferably, as shown in Figure 2 and Figure 8As shown, the sealing structure 4 is overlapped with the track 1, and the sealing structure 4 can be separated from the track 1. At this time, the sealing structure 4 is preferably a whole structure, and the size of the sealing structure 4 is the same as the size of the connecting port 11. Different connecting ports 11 are respectively sealed by a plurality of sealing structures 4, and the whole opening is sealed.

[0083] The sealing structure 4 is arranged between the first side plate 12 and the second side plate 13, and the lower side of the sealing structure 4 is provided with a sealing elastic piece 434, one end of the sealing elastic piece 434 abuts against the inner wall of the bottom plate of the track 1, and the other end of the sealing elastic piece 434 abuts against the inner wall of the sealing structure 4, and the sealing elastic piece 434 is used to apply an upward force to the sealing structure 4 to push the sealing structure 4 upward. The upper end of the first side plate 12 extends rearward to form a first baffle plate 435, and the upper end of the second side plate 13 extends forward to form a second baffle plate, and the distance between the first baffle plate 435 and the second baffle plate is greater than the width of the sealing structure 4. In order to prevent the sealing structure 4 from being ejected from the track 1.

[0084] The first baffle plate 435 and the second baffle plate limit the sealing structure 4 to prevent the sealing structure 4 from being ejected from the opening. When installing the adapter 2, only the adapter 2 is needed to directly press the sealing structure 4 downward to press the sealing structure 4 to the bottom of the track 1, which does not affect the installation and use of the adapter 2, and the sealing structure 4 does not need to be taken out. When the adapter 2 is taken out, the sealing structure 4 is lifted upward by the sealing elastic piece 434 to reseal the connecting port 11. Thus, the convenience of the adapter 2 during installation and use can be improved.

[0085] Further, as shown in Figure 1 and Figure 2 , the outer sides of the first side plate 12 and the second side plate 13 are further provided with a first outer plate 14 and a second outer plate 15, the first outer plate 14 and the first side plate 12 have a first accommodating space therebetween, and the second outer plate 15 and the second side plate 13 have a second accommodating space therebetween. The power cable 3 or the transmission cable for transmitting signals can be arranged in the accommodating space.

[0086] The power cable 3 and the transmission cable can be arranged in the first accommodating space and the second accommodating space respectively, so that the electromagnetic interference between the power cable 3 and the transmission cable can be avoided.

[0087] Further, the left and right ends of the track 1 are further provided with left and right sealing covers 16 and 17 for sealing the left and right end ports of the track 1, the first accommodating space and the second accommodating space.

[0088] In the existing power track 1 system, the adapter 2 "arm", the contact mode, the structure shape of the track 1 and the mechanical connection are associated, the power track 1 system and the power point are limited to a single-phase power supply, and the power transmission of a single-phase power supply is low, and the adapter 2 is easy to overload and cause safety hazards.

[0089] In order to solve the above problems, a cable 3 for power supply and / or a transmission cable for data transmission is arranged on the outer side of the track 1, and the cable 3 or the transmission cable is provided with at least one set, and the cable 3 or the transmission cable in the set is electrically connected to at least one adapter 2.

[0090] The transmission cable includes an HDMI cable, a USB cable, a network CAT6 cable, a telephone cable CAT3 cable, a coaxial cable, a DIN cable, etc.

[0091] The lines included in the set of cables 3 include a ground wire, a zero wire and a fire wire. In the set of cables 3, the fire wire can be provided with multiple, and the multiple fire wires can share a ground wire and a zero wire. Each fire wire can correspond to connect one or more adapters 2. When the adapter 2 connects a high-power electrical appliance, it avoids that the power is concentrated on one fire wire, but can be connected to different fire wires respectively, avoids the overload of the fire wire, and thus can provide stable power supply for the adapter 2.

[0092] As shown in Figure 9 A set of cables 3 can be arranged on the front side, the rear side and / or the lower side of the track 1. When the adapter 2 is less, for example, only two adapters 2, a set of cables 3 can also be arranged on the left and right sides of the track 1.

[0093] A set of cables 3 can be arranged on one side of the track 1.

[0094] The multiple lines in a set of cables 3 can be arranged on the front side, the rear side and / or the lower side of the track 1 respectively. For example, one or two lines in a set of cables 3 are arranged on one side of the track 1, and the other lines are arranged on the other side of the track 1.

[0095] When a set of cables 3 is arranged, the ground wire, the zero wire and the fire wire can be arranged on the same side of the track 1, for example, the ground wire, the zero wire and the fire wire can be arranged on the front side, the rear side and / or the lower side of the track 1 at the same time.

[0096] The ground wire, the zero wire and the fire wire in a set of cables 3 can be arranged on the front side, the rear side and / or the lower side of the track 1 respectively.

[0097] Two lines in a set of cables 3 can be arranged on the front side, the rear side and / or the lower side of the track 1.

[0098] The present application can have multiple hot wires to form multiple groups of single-phase power. Further, the present application can have individual control of each group of single-phase power, which significantly increases the power that can be transmitted. For example, a single group of single-phase power can carry 20A / 250V (5000W), and each additional group of single-phase power doubles the power. Thus, two groups allow (5000W x 2 = 10000W) of power. This calculation applies to any combination of single-phase power, such as 16A / 110V, 32A / 250V, 10A / 250V, etc.

[0099] When the cable 3 is electrically connected to the adapter 2, a screw terminal is usually used, which is slow to install on site and prone to human error, so professional training is required to ensure safe and correct installation.

[0100] To solve the above problems, preferably, the cable 3 includes bare wire parts and insulation parts, the bare wire parts are arranged at intervals, and the insulation parts are between adjacent bare wire parts. The insulation parts are connected to the conductive structure 5.

[0101] As shown in Figure 10 and Figure 11 , the conductive structure 5 includes a conductive conductive part 51 and an insulating clamping part 52, and the conductive part 51 is used to electrically connect the cable 3 and the adapter 2. The clamping part 52 is used to clamp the conductive part 51. The clamping part 52 includes a first clamping subpart 521 and a second clamping subpart 522, and the conductive part 51 is clamped between the first clamping subpart 521 and the second clamping subpart 522.

[0102] Further, the first clamping subpart 521 is provided with a fixing table 5211 clamped into the track 1 on the left and right sides, and the track 1 is provided with a fixing hole 4327 matched with the fixing table 5211, and the fixing table 5211 is inserted into the fixing hole 4327, so that the conductive structure 5 is fixedly connected with the track 1.

[0103] As shown in Figure 12 , the conductive part 51 includes an extension part 511 and a clamping part 512, the extension part 511 extends out of the clamping part 512 and is used to connect the contact point 24 of the adapter 2. The clamping part 512 is located on the inner side of the clamping part 52 and is used to clamp the bare wire part of the cable 3, and the electricity on the cable 3 is introduced to the adapter 2 through the conductive part 51.

[0104] The cross section of the extension part 511 is U-shaped, and the front side of the extension part 511 is electrically connected with the adapter 2. The extension part 511 greatly reduces the connection time of the adapter 2 and the cable 3, and provides more possibilities for on-site installation.

[0105] The clamping portion 512 includes a first clamping finger 5121 and a second clamping finger 5122 arranged on the lower portion, and a third clamping finger 5123 arranged on the upper portion, the first clamping finger 5121, the second clamping finger 5122 and the third clamping finger 5123 form a triangle, and two sides of the third clamping finger 5123 extend forward to form a connecting portion 513, and the connecting portion 513 is connected with the extending portion 511.

[0106] When the clamping portion 512 is connected with the bare wire portion of the cable 3, the bare wire portion of the cable 3 is clamped between the first clamping finger 5121, the second clamping finger 5122 and the third clamping finger 5123, and the first clamping finger 5121, the second clamping finger 5122 and the third clamping finger 5123 are pinched to firmly clamp the conductive member 51 on the cable 3. The first clamping finger 5121, the second clamping finger 5122 and the third clamping finger 5123 can accommodate cables 3 of various sizes. The arrangement of the cable 3 and the wire square can be used more flexibly to achieve more flexible connection.

[0107] The rear portion of the first clamping sub-member 521 and the second clamping sub-member 522 is provided with a receiving space for receiving the clamping portion 512 of the conductive member 51, and the cable 3 is inserted into the receiving space and clamped by the clamping portion 512 of the conductive member 51.

[0108] As shown in Figure 13 The middle portion of the front side of the first clamping sub-member 521 is provided with a boss 5212, the upper surface of the boss 5212 abuts against the lower surface of the connecting portion 513 of the conductive member 51, and the middle portion of the front side of the second clamping sub-member 522 is provided with an adaptive groove 5221 matched with the boss 5212, and the lower surface of the adaptive groove 5221 abuts against the upper surface of the connecting portion 513 of the conductive member 51, so that the conductive member 51 is clamped between the first clamping sub-member 521 and the second clamping sub-member 522 through the cooperation of the boss 5212 and the adaptive groove 5221.

[0109] The rear side of the first clamping sub-member 521 extends upward to form a buckle 5213, and the rear side of the second clamping sub-member 522 is provided with a clamping platform 5222 matched with the buckle 5213, and the buckle 5213 can be clamped on the clamping platform 5222. The front side of the first clamping sub-member 521 is provided with a buckling groove 5214 upward and downward, and the front side of the second clamping sub-member 522 is provided with a buckling column 5223 matched with the buckling groove 5214, and the buckling column 5223 can be buckled into the buckling groove 5214. The rear side of the first clamping sub-member 521 and the second clamping sub-member 522 are tightly connected through the cooperation of the buckle 5213 and the clamping platform 5222. The front side of the first clamping sub-member 521 and the second clamping sub-member 522 are tightly connected through the cooperation of the buckling column 5223 and the buckling groove 5214. Thus, the conductive member 51 is tightly clamped between the first clamping sub-member 521 and the second clamping sub-member 522.

[0110] Further, asFigure 14 As shown, the two sides of the fitting groove 5221 of the second clamping sub-piece 522 are also provided with limiting platforms 5224, which are in contact with the combination part 513 of the conductive piece 51, limiting the freedom of the conductive piece 51 and preventing the conductive piece 51 from moving left and right.

[0111] Preferably, the middle part of the contact position between the combination part 513 and the limiting platform 5224 protrudes towards the limiting platform 5224, which not only limits the freedom, but also reduces the contact area between the conductive piece 51 and the limiting platform 5224, thereby improving the safety of the conductive structure 5 in use.

[0112] The power distribution device includes a track 1 and an adapter 2. When the adapter 2 is installed in the track 1, the adapter 2 can be installed in the track 1 by means of bonding, magnetic attraction, screwing, willow connection, pin connection and / or clamping, etc.

[0113] When the adapter 2 is installed by bonding, PVC glue, PP glue, PE glue, PU glue, ABS glue, TPR glue, etc. can be used to install the adapter 2 in the track 1. Or use the double-sided adhesive tape of the plastic adhesive for easy disassembly, such as the non-woven fabric substrate double-sided adhesive tape and PET substrate double-sided adhesive tape in 3M double-sided adhesive tape. The adapter 2 is installed in the track 1 by gluing.

[0114] When the adapter 2 is installed by magnetic attraction, a magnet with magnetism can be arranged in the track 1. The magnet can be arranged on the inner wall of the track 1. Correspondingly, a metal sheet that can be magnetically attracted is arranged on the adapter 2. The metal sheet is made of iron, iron alloy, nickel, cobalt, etc. The adapter 2 is installed in the track 1 by the attraction of the magnet and the metal sheet.

[0115] When the adapter 2 is installed by screwing, willow connection or pin connection, the adapter 2 can be installed in the track 1 by bolts, screws or pins.

[0116] When the adapter 2 is installed by clamping, a boss 5212 or a groove 4323 can be arranged on the inner wall of the track 1, and correspondingly a groove 4323 or a boss 5212 is arranged on the adapter 2. The boss 5212 and the groove 4323 can be semicircular, square or dovetail-shaped, etc. The adapter 2 is installed in the track 1 by the clamping of the groove 4323 and the boss 5212.

[0117] Although the above-mentioned methods can install the adapter 2 in the track 1, the installation of the adapter 2 is relatively cumbersome, the installation efficiency is low, and specific installation tools, installation materials or adapted tracks 1 and adapters 2 are required, which brings great inconvenience to the installation of the adapter 2.

[0118] In order to solve the above problems, preferably, as shown in Figure 15 , Figure 16 andFigure 17 As shown in the figure, the track 1 is provided with a locking structure 6 for locking the adapter 2. The adapter 2 can be quickly installed in the track 1 through the locking structure 6.

[0119] The locking structure 6 includes a locking piece 61 for locking the adapter 2 and a locking elastic piece 62 for elastically pressing the locking piece 61. The locking piece 61 includes a locking body part 611 and a locking part 612 connected to the upper end of the locking body part 611 and extending to the right. The adapter 2 is provided with a locking hole 2111 matched with the locking part 612. Under the elastic action of the locking elastic piece 62, the locking part 612 is pressed into the locking hole 2111 of the adapter 2 to lock the adapter 2.

[0120] The locking elastic piece 62 can be a spring. The lower end of the locking body part 611 can be fixed on the bottom plate of the track 1 or hinged on the side wall of the track 1. One end of the spring can be fixed on the upper end of the locking body part 611, and the other end can be fixed on the side wall of the track 1. Thus, the locking part 612 connected to the upper end of the locking body part 611 can be pressed into the locking hole 2111 by the elastic force.

[0121] Preferably, the locking elastic piece 62 is an elastic sheet with an arc. The upper end of the elastic sheet is sleeved or fixed on the upper end of the locking body part 611, the lower end of the elastic sheet is attached to the locking body part 611, and the middle part of the elastic sheet with the arc position is in contact with the inner wall of the track 1. The locking part 612 connected to the upper end of the locking body part 611 can be pressed into the locking hole 2111 by the elastic sheet. At this time, the lower end of the locking body part 611 can also be fixed on the bottom plate of the track 1 or hinged on the side wall of the track 1.

[0122] In the above-mentioned mode, the locking structure 6 is fixedly arranged and cannot move up and down, and it is not convenient for the locking structure 6 to lock the adapter 2.

[0123] Further, in order to make the locking structure 6 conveniently lock the adapter 2, the locking structure 6 further includes a locking fixing piece 63271. The locking fixing piece 63271 includes a first fixing sub-piece 631 and a second fixing sub-piece 632. The first fixing sub-piece 631 is fixed on the bottom plate of the track 1, and the second fixing sub-piece 632 is buckled on the first fixing sub-piece 631.

[0124] The first fixing sub-piece 631 includes a first sub-fixing part 6311 arranged horizontally on the lower side and a first sub-limiting part 6312 arranged vertically on the upper side of the first sub-fixing part 6311. The first sub-limiting part 6312 is used to arrange a locking sliding groove 6324.

[0125] The second fixing sub-member comprises a first sub-engaging part 6322, which has a receiving space in which a supporting elastic member 64 is arranged. The lower end of the engaging main body part 611 is provided with an engaging sleeve part 613 which is adapted to the supporting elastic member 64. The supporting elastic member 64 is sleeved on the periphery of the engaging sleeve part 613. The supporting elastic member 64 is used to provide an upward elastic force to the engaging member 61 to elastically move the engaging member 61 upward.

[0126] Further, the first fixing sub-member 631 and the second fixing sub-member 632 are provided with an engaging sliding groove 6324. The lower part of the engaging main body part 611 is provided with an engaging sliding part 614 which is adapted to the engaging sliding groove 6324. The engaging sliding part 614 can move up and down in the engaging sliding groove 6324. Under the elastic force of the supporting elastic member 64, the engaging sliding part 614 can move upward in the engaging sliding groove 6324, so that the engaging member 61 can be moved upward by the supporting elastic member 64. The engaging sliding groove 6324 simultaneously plays a limiting role to avoid the ejection of the engaging sliding part 614. Under the action of external force, the engaging sliding part 614 can move downward in the engaging sliding groove 6324.

[0127] Further, the upper end of the second fixing sub-member 632 is further provided with an engaging limiting groove 6322. The middle part of the engaging main body part 611 is provided with an engaging limiting part 615 which is adapted to the engaging limiting groove 6322. The engaging limiting groove 6322 comprises a horizontal groove and a vertical groove. The connecting part of the horizontal groove and the vertical groove has a curvature, which can facilitate the smooth sliding of the engaging limiting part 615 in the horizontal groove and the vertical groove.

[0128] When the engaging limiting part 615 is at the vertical groove, the supporting elastic member 64 can elastically move the engaging member 61 upward. When the engaging limiting part 615 is at the horizontal groove, the vertical groove limits the engaging limiting part 615, and the supporting elastic member 64 cannot elastically move the engaging member 61 upward, thereby limiting the position of the engaging member 61.

[0129] Preferably, when the engaging limiting part 615 is at the horizontal groove, the engaging part 612 is pressed into the engaging hole 2111 of the adapter 2 to lock the adapter 2.

[0130] Further, as shown in Figure 16 , Figure 17 and 18 , the engaging structure 6 further comprises a sealing limiting member 65 which limits the sealing structure 4. The sealing structure 4 has a first baffle plate 435 and a second baffle plate protruding from the side surface of the track 1. When the sealing limiting member 65 is below the first baffle plate 435 and the second baffle plate, the sealing limiting member 65 limits the downward movement of the sealing structure 4. When the sealing limiting member 65 is away from below the first baffle plate 435 and the second baffle plate, the sealing structure 4 can move downward under the action of external force.

[0131] The sealing limiting member 65 comprises a sealing body part 651, a plug-in part 652 extending from one side of the sealing body part 651, a plug-in slot 653 between the sealing body part 651 and the plug-in part 652, and a sealing unlocking part 616 extending from the upper end of the locking body part 611 and adapted to the plug-in slot 653.

[0132] When the locking member 61 moves up and down, the sealing unlocking part 616 moves up and down, so that it can move up and down in the sealing plug-in slot 653. Preferably, the joint between the sealing plug-in part 652 and the sealing unlocking part 616 is chamfered, so that the sealing unlocking part 616 can be smoothly inserted into the sealing plug-in slot 653.

[0133] When the locking member 61 is on the upper side, the sealing body part 651 of the sealing limiting member 65 is below the first baffle 435 and the second baffle, defining the sealing structure 4 and preventing the sealing structure 4 from moving downward.

[0134] When an external force is applied to the upper end of the locking member 61, the locking member 61 moves downward, the sealing unlocking part 616 moves downward, the sealing unlocking part 616 gradually inserts into the sealing plug-in slot 653 from top to bottom, and the sealing limiting member 65 moves away from below the first baffle 435 and the second baffle, at this time the sealing structure 4 can move downward under the action of the external force.

[0135] Preferably, the bottom of the adapter 2 extends downward with a protrusion adapted to the locking member 61, the locking member 61 is pressed by the adapter 2, the downward force is applied to the locking member 61, and the adapter 2 and the sealing structure 4 can move downward at the same time.

[0136] Preferably, the lower end of the sealing body part 651 extends with a sealing sliding part 654, the right side of the first fixed part 631 extends with two fixed part extension parts 6313, and the two fixed part extension parts 6313 enclose a sealing sliding slot 6314 adapted to the sealing sliding part 654. The sealing sliding part 654 can move left and right in the sealing sliding slot 6314.

[0137] The free end of the sealing limiting member 65 is limited by the sealing sliding part 654 and the sealing sliding slot 6314, so that the sealing limiting member 65 can only move left and right, but not up and down, so that the sealing limiting member 65 is below the first baffle 435 and the second baffle, or away from below the first baffle 435 and the second baffle.

[0138] Further, the sealing body part 651 is vertically provided with a sealing limiting groove 655 adjacent to the side of the locking member 61, and the locking member 61 is provided with a limiting rod 617 adapted to the sealing limiting groove 655 adjacent to the side of the sealing body part 651. The sealing limiting groove 655 comprises a vertical groove and a horizontal groove, and when the limiting rod 617 moves from top to bottom, it can slide from the vertical groove into the horizontal groove. When the limiting rod 617 slides to the horizontal groove, the movement of the limiting rod 617 is limited by the horizontal groove, that is, the upward movement of the locking member 61 is limited by the sealing limiting member 65.

[0139] Preferably, as shown in Figure 8 and Figure 15 When the adapter 2 is locked by the locking structure 6, the locking structure 6 is provided with four, and the four locking structures 6 are respectively arranged at the four corners of the adapter 2. The four corners of the adapter 2 are provided with locking holes 2111 adapted to the locking parts 612, and the locking parts 612 are clamped in the locking holes 2111 to lock the adapter 2.

[0140] Preferably, when the locking structure 6 has four, the sealing body part 651 of the locking structure 6 on the same side is further provided with an elastic connecting member 66, one end of the elastic connecting member 66 is connected with one sealing body part 651, and the other end of the elastic connecting member 66 is connected with another sealing body part 651. Under the action of the elasticity of the elastic connecting member 66, the sealing limiting member 65 is automatically moved below the first baffle 435 and the second baffle of the locking member 61, and the sealing limiting member 65 limits the downward movement of the sealing structure 4.

[0141] As shown in Figure 8 and Figure 15 By the above-mentioned locking structure 6, the adapter 2 can be locked when the adapter 2 is installed, and the sealing structure 4 can be locked by the locking structure 6 after the adapter 2 is taken out.

[0142] Further, as shown in Figure 2 , Figure 18 and Figure 19 The track 1 between the locking structures 6 is further provided with a track inner plate 18, and the track inner plate 18 comprises a pressing plate 181 at the bottom. The pressing plate 181 is used to clamp and fix the locking structure 6.

[0143] The first fixing member 271 extends a pressing groove 6315, and the four corners of the pressing plate 181 are provided with a pressing part 182 adapted to the pressing groove 6315, and the pressing part 182 extends a pressing table 183 downward, and the pressing table 183 is inserted into the pressing groove 6315. The first fixing member 271 is fixed at the bottom of the adapter 2 by the pressing table 183.

[0144] The existing track 1 system has at least one slot along the track 1. The slot can be partially covered by elastic material or plastic sheet, but not completely covered. The slot poses a safety hazard because there is always a risk of touching the live parts. The existing track 1 system tries to alleviate this risk by designing mechanisms to set the live parts away from the slot or to prevent the foreign body from directly contacting the live parts. Some track 1 uses a grounded conductive part to shield the slot, and when the live part is accidentally touched, the current can flow from the grounded conductive part to avoid and reduce the risk of electric shock. Even with the grounded conductive part, the safety of the system is not inherent because it relies on external circuit breakers, and if there are no circuit breakers, there is a risk of fire when short-circuiting. In addition, if the misoperation causes the grounded conductive part to be damaged, the short circuit may occur due to the deformation of the conductive part.

[0145] To solve the above problems, preferably, the inner plate 18 of the track is further provided with a first inner plate 184 adjacent to one side of the cable 3, and the first inner plate 184 is provided with a connecting part 1841 adapted to the conductive structure 5, and the conductive structure 5 is at the connecting part 1841, and the end of the conductive structure 5 can extend into the track 1 and be electrically connected with the adapter 2.

[0146] The first inner plate 184 makes the electrical connection with the adapter 2 only at the connecting part 1841, without touching the contact point 24 on the conductive structure 5 and the adapter 2, thereby eliminating any risk of touching the live parts.

[0147] Preferably, the inner plate 18 of the track is further provided with a second inner plate 185 away from the cable 3, and the second inner plate 185 is used to define the sealing sliding part 654 of the sealing limiting part 65, and prevent the sealing sliding part 654 from sliding out of the first fixing part 271.

[0148] Further, a baffle or shutter can also be provided on the outside of the first inner plate 184 to further ensure that the conductive structure 5 and the contact point 24 on the adapter 2 are not touched, and further eliminate the risk of touching the live parts. The baffle is adapted to the shape of the first inner plate, and the shutter is two baffles that can have relative motion, and the shutter is adapted to the first inner plate.

[0149] Further, the first inner plate 184 and the second inner plate 185 are provided with a clamping hook 186 clamping the first fixing part 271 on both sides. The two first fixing parts 271 are further fixedly connected by the clamping hook 186.

[0150] The existing track system cannot randomly or when powered, plug or replace the adapter, such as replacing the adapter with a wireless charger or USB charger, or replacing the adapter with a signal output point, or replacing the British standard adapter with a Chinese standard adapter, etc. And can not be randomly converted from the adapter to the signal output point. It can not be replaced with a Chinese standard or British standard adapter with an HDMI signal output, or a USB charger adapter with a USB signal output point.

[0151] Although the conventional track system can replace the adapter, the conventional track system needs to assemble the adapter before leaving the factory, and also needs to terminate each adapter one by one. In addition, the track system is not easy to expand, and needs professional personnel to operate when powered. At the same time, the power point system cannot be randomly disassembled or replaced after installation.

[0152] The following is only an example of a Chinese standard adapter, and those skilled in the art can use HDMI signal output units and other structures to replace.

[0153] When the adapter 2 is locked by the locking structure 6, in order to facilitate the replacement of the adapter 2, the adapter 2 is provided with an unlocking structure 23, as shown in Figure 21 , Figure 22 and Figure 23 The unlocking structure 23 includes an unlocking piece 231 adapted to the locking hole 2111 of the adapter 2, and an unlocking driving piece 232 for sliding the unlocking piece 231; the unlocking structure 23 unlocks the adapter 2 when the unlocking piece 231 enters the locking hole 2111.

[0154] When the locking hole 2111 has four, the unlocking piece 231 corresponding to the locking hole 2111 has four, preferably as shown in Figure 24 The unlocking driving piece 232 includes two, one unlocking driving piece 232 is connected to two unlocking pieces 231 respectively.

[0155] One end of the unlocking driving piece 232 is connected to one unlocking piece 231, and the other end of the unlocking driving piece 232 is connected to another unlocking piece 231.

[0156] The connection mode of the unlocking driving piece 232 and the unlocking piece 231 includes fixed connection, buckle 5213 connection, etc.

[0157] The unlocking driving member 232 has two states, namely a retracted state and an extended state, in the retracted state, the unlocking driving member 232 drives the unlocking member 231 to be away from the locking hole 2111, at this time, the locking part 612 of the locking structure 6 can be clamped in the locking hole 2111 to lock the adapter 2. In the extended state, the unlocking driving member 232 drives the unlocking member 231 to be inserted into the locking hole 2111, and the locking part 612 of the locking structure 6 is extruded from the locking hole 2111 by the unlocking member 231, so that the adapter 2 can be unlocked.

[0158] The unlocking driving member 232 can be a telescopic structure, for example, a sleeve rod, a spring piece or the like.

[0159] Preferably, the unlocking driving member 232 is a spring piece with elasticity and has a protruding part 2321, the spring piece is in the retracted state as a normal state, that is, the spring piece is always in the retracted state when not subjected to external force, at this time, the unlocking member 231 is away from the locking hole 2111. When the protruding part 2321 of the spring piece is pressed by external force, the spring piece is extended, and the state is changed from the retracted state to the extended state, the two ends of the spring piece extrude the unlocking member 231 into the locking hole 2111, and the unlocking member 231 extrudes the locking part 612 of the locking structure 6 from the locking hole 2111, so that the adapter 2 can be unlocked.

[0160] Further, as shown in Figure 24 , the lower part of the unlocking member 231 further extends a blocking part 2311 to prevent the unlocking member 231 from sliding out excessively.

[0161] In the present application, the adapter 2 can be conveniently taken out by the unlocking structure 23, and the adapter 2 can be replaced, and in combination with the contact point 24 of the adapter 2 and the conductive structure 5, the user does not need to connect the line again, which can greatly improve the convenience and safety of replacing the adapter 2.

[0162] Preferably, as shown in Figure 22 and Figure 23 , the adapter 2 is provided with a supporting member 233 for supporting the unlocking driving member 232, the supporting member 233 is arranged on the upper part of the adapter 2 housing 21 and on the lower side of the adapter 2 locking hole 2111, and is used for supporting the unlocking driving member 232, when the unlocking driving member 232 is a spring piece, the spring piece is prevented from being pressed excessively.

[0163] Preferably, the supporting member 233 is connected with the moving inner shell 22 buckle 5213.

[0164] Preferably, as shown in Figure 21 and Figure 22As shown, preferably, the unlocking driving member 232 further comprises an unlocking pressing member 234 capable of moving up and down, the unlocking pressing member 234 is arranged on the upper side of the supporting member 233, and the supporting member 233 has a containing space between the housing 21, the unlocking pressing member 234 is arranged in the containing space and is capable of moving up and down in the containing space. When an external force is applied to the unlocking pressing member 234, the unlocking pressing member 234 moves downward, presses the protruding part 2321 of the elastic sheet, and makes the elastic sheet stretch, changes from the contracted state to the stretched state, and the two ends of the elastic sheet press the unlocking member 231 into the locking hole 2111, and the unlocking member 231 extrudes the locking part 612 of the locking structure 6 from the locking hole 2111, so that the adapter 2 can be unlocked.

[0165] Preferably, the unlocking pressing member 234 comprises a left unlocking pressing member 234 and a right unlocking pressing member 234, and the left unlocking pressing member 234 and the right unlocking pressing member 234 have an opening for exposing the power taking position of the adapter 2.

[0166] The prior art has the problem that there must be a track electrical connection part. This part is usually very thin. Because it is limited by the track slot. Therefore, the current, wattage, and temperature are also limited, and are easily affected by high temperature. At high temperature, the thin plastic part is easily deformed, and even melts, which has a safety hazard. In order to reduce the temperature and wattage limit, the type of material used also needs to be improved, and the cost is also increased. The prior art also has the problem of complex production process. The track electrical connection part usually needs to accommodate the conductors of fire, ground, and zero line, and should be space-limited, and the insulation space of each conductor is very small, which leads to the possibility that the voltage will break the insulator if the voltage is unstable and an electric surge (voltage momentary high) occurs. At the same time, the insulation part also needs to be precisely controlled during injection molding, and if there are bubbles or injection molding defects, short circuit will occur. Therefore, the efficiency is low, the waste is much, and the overall cost is increased.

[0167] Further, in order to solve the above problems, as shown in Figure 21 and Figure 22 The adapter 2 in the present application is provided with a contact point 24 electrically connected with the conductive structure 5.

[0168] Preferably, as shown in Figure 22 and 25 The adapter 2 comprises a housing 21, and a power taking member 25 arranged in the housing 21 for taking power, the power taking member 25 is connected with a conductive intermediate member 26, the end of the intermediate member 26 is connected with the contact point 24, the contact point 24 protrudes from the housing 21 and is exposed to electrically connect with the extension part 511 of the cable 3 or the conductive member 51.

[0169] The contact point 24 can be further provided with a plurality of adjacent contact points 24 connected to form a straight line or a polygon.

[0170] Preferably, the power taking part 25 is provided with an insulating sealing part 2343 outside. The sealing part 2343 is provided with a socket matched with the power taking part 25.

[0171] The power taking part 25 includes two or three. When the power taking part 25 is two, the power taking part 25 is respectively a zero line sub power taking part 251 connected with the zero line and a fire line sub power taking part 252 connected with the fire line. When the power taking part 25 is three, it further includes a ground line sub power taking part 253 connected with the ground line.

[0172] The zero line sub power taking part 251 includes two-pole zero line plug sleeve, and the fire line sub power taking part 252 includes two-pole fire line plug sleeve. The two-pole plug can be inserted into the two-pole zero line plug sleeve and the two-pole fire line plug sleeve to take power.

[0173] The two-pole zero line plug sleeve and the two-pole fire line plug sleeve are matched with the two-pole plug.

[0174] The two-pole zero line plug sleeve and the two-pole fire line plug sleeve are matched with the flat and / or round two-pole plug.

[0175] When the two-pole zero line plug sleeve and the two-pole fire line plug sleeve are flat, they can be matched with the flat two-pole plug. At this time, a round slot is arranged in the middle of the two-pole zero line plug sleeve and the two-pole fire line plug sleeve, which can be matched with the round two-pole plug at the same time.

[0176] The zero line sub power taking part 251 further includes three-pole zero line plug sleeve, the fire line sub power taking part 252 further includes three-pole fire line plug sleeve, and the ground line sub power taking part 253 includes three-pole ground line plug sleeve. The three-pole plug can be inserted into the three-pole zero line plug sleeve, the three-pole fire line plug sleeve and the three-pole ground line plug sleeve to take power.

[0177] The three-pole zero line plug sleeve, the three-pole fire line plug sleeve and the three-pole ground line plug sleeve are matched with the three-pole plug.

[0178] The three-pole zero line plug sleeve, the three-pole fire line plug sleeve and the three-pole ground line plug sleeve are matched with the flat and / or round three-pole plug.

[0179] When the three-pole zero line plug sleeve, the three-pole fire line plug sleeve and the three-pole ground line plug sleeve are flat, they can be matched with the flat three-pole plug. At this time, a round slot is arranged in the middle of the three-pole zero line plug sleeve, the three-pole fire line plug sleeve and the three-pole ground line plug sleeve, which can be matched with the round three-pole plug at the same time.

[0180] The intermediate part 26 corresponding to the power taking part 25 includes two or three. When the intermediate part 26 is two, the intermediate part 26 is respectively a zero line sub intermediate part 261 connected with the zero line sub power taking part 251 and a fire line sub intermediate part 262 connected with the fire line sub power taking part 252. When the intermediate part 26 is three, it further includes a ground line sub intermediate part 263 connected with the ground line sub power taking part 253.

[0181] The contact points 24 corresponding to the intermediate piece 26 preferably include two or three, and when the contact points 24 are two, the contact points 24 are respectively a zero line sub-contact point 241 connected to the zero line and a fire line sub-contact point 242 connected to the fire line. When the contact points 24 are three, the contact points 24 further include a ground line sub-contact point 243 connected to the ground line.

[0182] The intermediate piece 26 includes a transversely arranged extension 2622, which is electrically connected to the power taking piece 25 for placing the contact points 24 at the inner wall of the adapter 2 housing 21. The extension 2622 can be directly electrically connected to the contact points 24. However, this way is not convenient for adjusting the position of the contact points 24. That is, the zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243 are at the same height, and when the zero line, the fire line and the ground line are all in a plane transversely to the contact points 24, it is not convenient for the electrical connection of the contact points 24 with the zero line, the fire line and the ground line.

[0183] Preferably, the intermediate piece 26 further includes a vertically arranged power connection part 2623, which is electrically connected to the contact points 24. The contact points 24 can be arranged at different positions on the power connection part 2623. Thus, the zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243 can be arranged at different heights according to the needs of the electrical connection of the cable 3. Thus, the electrical connection mode has diversity. It is convenient for the electrical connection of the contact points 24 with the cable 3.

[0184] The zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243 can form various shapes when their heights are different. For example, the zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243 can form a straight line, which can be arranged at an arbitrary inclination angle according to needs. The zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243 can form a triangle. The angles of each angle of the triangle can be adjusted arbitrarily according to needs. The zero line, the fire line and the ground line can be adaptively arranged according to the shape and position of the zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243. The zero line sub-contact point 241, the fire line sub-contact point 242 and the ground line sub-contact point 243 can also be adaptively manufactured according to the arrangement shape and position of the zero line, the fire line and the ground line.

[0185] The flexibility of the arrangement of the contact points 24 of the adapter 2 of the present application is greatly increased, and the wattage can be more required to improve or the arrangement of the adapter 2 is used as a separate control and distinction for power taking.

[0186] If the adapter 2 does not have a switching device, the conductor of the track 1 and the contact of the adapter 2 will not only have physical friction, but also electric arc, which will cause faster wear and greatly reduce the service life and safety of the product.

[0187] The adapter 2 may also contain a switch, whereas in the prior art, the switch is usually located on one side of the housing, occupying space on the surface of the housing.

[0188] Furthermore, such as Figure 26 and Figure 27 As shown, the adapter 2 has a movable inner shell 22 that can move up and down inside the housing 21. The power taking part 25 is fixed on the movable inner shell 22, and the intermediate part 26 is fixed on the bottom of the adapter 2. The intermediate part 26 is also electrically connected to a switch structure 27, which is used to control the power supply and power de-energization of the adapter 2.

[0189] The live wire intermediate component 262 is electrically connected to the switch structure 27. One end of the live wire intermediate component 262 is connected to the live wire power take-off component 252, and the other end of the live wire intermediate component 262 is provided with a first contact 2621.

[0190] A switch structure 27 is disposed at the bottom of the adapter 2 housing 21. The switch structure 27 includes a fixing member 271 and a switch member 272 movably connected to the fixing member 271. The fixing member 271 is fixed to the bottom of the adapter 2 housing 21 and is used to connect the live wire intermediate member 262 and the three-pole live wire socket. The switch member 272 is provided with a second contact 2721, which is used to electrically connect to the first contact 2621. When the second contact 2721 is electrically connected to the first contact 2621, the adapter 2 is energized; when the second contact 2721 is disconnected from the first contact 2621, the adapter 2 is de-energized.

[0191] like Figure 28 and Figure 29 As shown, the switch 272 is movably connected to the fixed member 271, and the switch 272 can move up and down, rotate, or move up and down and rotate simultaneously relative to the fixed member 271.

[0192] The switch 272 includes a first movable end 2722 and a second movable end 2723. A second contact 2721 is disposed on the upper surface of the first movable end 2722. The second contact 2721 can switch between a first state and a second state. In the first state, the second contact 2721 is electrically connected to the first contact 2621 to connect the live wire intermediate component 262 and the live wire power take-off component 252 through the switch structure 27. In the second state, the second contact 2721 is disconnected from the first contact 2621 to disconnect the live wire intermediate component 262 from the live wire power take-off component 252 through the switch structure 27. By connecting and disconnecting the second contact 2721 from the first contact 2621, the connection and disconnection of the live wire intermediate component 262 and the live wire power take-off component 252 are realized, thereby realizing the power supply and de-energization of the adapter 2.

[0193] Preferred, such as Figure 28 and Figure 29As shown, the up and down movement of the first movable end 2722 is controlled by the second movable end 2723, which makes the second contact 2721 connect or disconnect with the first contact 2621, and makes the adapter 2 be powered or lose power.

[0194] The switch part 272 can be sleeved on the fixed part 271 in transition fit. When the second movable end 2723 is pressed down, the switch part 272 moves down as a whole, which makes the second contact 2721 disconnect with the first contact 2621, and the adapter 2 loses power. When the second movable end 2723 moves up, the switch part 272 moves up as a whole, which makes the first movable end 2722 move up, and the second contact 2721 connects with the first contact 2621, and the adapter 2 is powered.

[0195] The switch part 272 can be hinged with the fixed part 271. When the second movable end 2723 is pressed down, the first movable end 2722 moves up, which makes the second contact 2721 connect with the first contact 2621, and the adapter 2 is powered. When the second movable end 2723 moves up, the first movable end 2722 moves down, which makes the second contact 2721 disconnect with the first contact 2621, and the adapter 2 loses power.

[0196] Preferably, as shown in Figure 28 and Figure 29 The switch part 272 is sleeved outside the fixed part 271, and the switch part 272 can not be in contact with the fixed part 271. At this time, the switch structure 27 further comprises a first pressing part 273 and a second pressing part 274. The first pressing part 273 is used to support the switch part 272, and the second pressing part 274 is used to drive the up and down movement of the first movable end 2722.

[0197] The fixing member 271 comprises a fixing base, a first extension part 2711 connected with the live wire sub-intermediate part 262, a second extension part 2712 connected with the switch member 272, a third extension part 2713 connected with the second extension part 2712, and a fourth extension part 2714 connected with the third extension part 2713. The fixing base is L-shaped, the first extension part 2711 extends upward at one end of the base, the second extension part 2712 extends upward at the other end of the base, the third extension part 2713 is connected with the second extension part 2712 and further extends toward the first extension part 2711, and the fourth extension part 2714 is connected with the third extension part 2713 and further extends upward. A first clamping groove 2715 is arranged at the joint of the second extension part 2712 and the third extension part 2713, a second clamping groove 2716 is arranged at the joint of the third extension part 2713 and the fourth extension part 2714, and a third clamping groove 2724 is arranged at the first movable end 2722 of the second contact 2721. One end of the first pressure sub-member is clamped in the second clamping groove 2716, and the other end of the first pressure sub-member is clamped below the second movable end 2723. One end of the second pressure sub-member is clamped in the second clamping groove 2716, and the other end of the second pressure sub-member is clamped in the third clamping groove 2724.

[0198] In the prior art, if the switch device is in the open configuration in the case of overload combustion or external damage, it cannot automatically cut off the power and must use an additional power cut-off device.

[0199] To solve the above problems, preferably, as shown in Figure 27 the second movable end 2723 is moved by moving the inner shell 22, and the first movable end 2722 is moved by the second movable end 2723 through the first pressure sub-member and the second pressure sub-member. The second contact 2721 is connected or disconnected with the first contact 2621, and the adapter 2 is powered on or powered off.

[0200] Further, the bottom of the moving inner shell 22 is provided with a switch elastic member 275 for moving the moving inner shell 22 upward. One end of the switch elastic member 275 is fixed to the lower surface of the bottom of the moving inner shell 22, and the other end is fixed to the upper surface of the bottom of the adapter 2. The moving inner shell 22 extends a pressure part 221 adjacent to the switch structure 27, and the pressure part 221 is below the second movable end 2723 of the switch member 272. The first pressure sub-member and the second pressure sub-member are both elastic.

[0201] Preferably, under the action of external force, the inner shell 22 moves downward, the pressing part 221 moves away from the second movable end 2723, the first pressing part 273 provides upward force to the second movable end 2723, and the second pressing part 274 provides downward force to the first movable end 2722, so that the first movable end 2722 moves downward, the second contact 2721 is disconnected from the first contact 2621, and the adapter 2 loses power. After the external force is removed, the inner shell 22 moves upward under the action of the switch elastic part 275, the pressing part 221 provides upward force to the second movable end 2723, the action of the first pressing part 273 on the second movable end 2723 is disabled, the second pressing part 274 provides upward force to the first movable end 2722, the first movable end 2722 moves upward, the second contact 2721 is connected to the first contact 2621, and the adapter 2 obtains power. Thus, the inner shell 22 loses power when it is on the lower side, and obtains power when it is on the upper side. That is, after the adapter 2 is inserted into the track 1, the contact 24 of the adapter 2 is always connected to the conductive structure 5, without wear and without electric arc. When the inner shell 22 of the adapter 2 is on the lower side of the track 1, the second contact 2721 of the switch mechanism is disconnected from the first contact 2621 on the intermediate part 26, that is, the switch structure 27 is always off. In the case of failure of the associated part of the switch of the adapter 2, or external force breakage, overload burning, etc., the adapter 2 can automatically change to the default off configuration. Thus, the service life and safety of the adapter 2 can be greatly improved.

[0202] Preferably, the upper end of the adapter 2 is provided with an inner shell pressing part 276 for pressing the inner shell 22, the inner shell pressing part 276 covers the upper end of the inner shell 22, and the inner shell pressing part 276 is provided with a socket adapted to the power taking part 25.

[0203] Preferably, when the inner shell 22 is pressed to the lower side of the adapter 2, the upper end surface of the inner shell pressing part 276 is flush with or close to the upper end surface of the track 1, and at this time the adapter 2 loses power. When the inner shell 22 is on the upper side of the adapter 2, the upper end surface of the inner shell pressing part 276 slightly protrudes from the upper end surface of the track 1, and at this time the adapter 2 obtains power.

[0204] The inner shell 22 loses power when it is on the lower side, and obtains power when it is on the upper side. Those skilled in the art can set a stop block 4326 outside the adapter 2 to limit the position of the inner shell 22 on the upper side and the lower side.

[0205] Preferably, as shown in Figure 22 , Figure 27 , Figure 30 and Figure 31 , the adapter 2 is further provided with a stroke structure 28 for locking the position of the inner shell 22. When the inner shell 22 moves to the lower end of the adapter 2, the stroke structure 28 locks the inner shell 22.

[0206] The movable inner shell 22 has a protruding inner shell limiting part 224 near the travel structure 28. The travel structure 28 includes a travel fixing part 281, a travel sliding part 282, and a travel limiting part 283. The travel fixing part 281 has a travel groove 2811, and a travel limiting block 2812 is provided in the middle of the travel groove 2811. A limiting groove 2813 is provided on the lower side of the travel limiting block 2812. One end of the travel sliding part 282 can slide counterclockwise in the travel groove 2811, and the other end of the travel sliding part 282 can engage with the power sub-component of the travel limiting part 283, so that the travel limiting sub-component 2833 of the travel limiting part 283 locks the movable inner shell 22 on the upper side of the limiting platform 5224.

[0207] The travel fixing component 281 is fixed to the bottom of the adapter 2. The travel fixing component 281 has a travel groove 2811 in the middle, a travel limit block 2812 in the middle of the travel groove 2811, and a limit groove 2813 on the lower side of the travel limit block 2812.

[0208] The stroke slider 282 includes a stroke sliding part 2821 arranged in front and back and a stroke linkage part 2822 arranged in left and right. The end of the stroke sliding part 2821 is disposed in the stroke groove 2811 and can move counterclockwise around the stroke limit block 2812 in the stroke groove 2811.

[0209] like Figure 32 As shown, within the travel groove 2811, five limiting points are set according to the position of the travel sliding part 2821 in the travel groove 2811, namely the first limiting point 28111, the second limiting point 28112, the third limiting point 28113, the fourth limiting point 28114, and the fifth limiting point 28115. When the travel sliding part 2821 is located at the first limiting point 28111, the moving inner shell 22 is at the uppermost end of the adapter 2, and the adapter 2 is energized and in a normally open state. When the moving inner shell 22 is pressed under external force, the travel sliding part 2821 moves from the first limiting point 28111, through the second limiting point 28112, to the third limiting point 28113, which is the lowermost moving position of the moving inner shell 22. When the external force is removed, the inner shell 22 moves upward under the action of the switch elastic element 275, and the travel sliding part 2821 slides from the third limit point 28113 to the fourth limit point 28114. At this time, the adapter 2 loses power and changes from the normally open state to the normally closed state.

[0210] When the inner shell 22 is pressed again under the action of an external force, the stroke sliding part 2821 slides from the fourth limit point 28114 to the fifth limit point 28115, and the external force is removed. Under the action of the switch elastic element 275, the moving inner shell 22 is pushed upward. When the moving inner shell 22 moves to the uppermost end, the stroke sliding part 2821 slides from the fifth limit point 28115 to the fourth limit point 28114, and the adapter 2 is powered. The state is switched from the normally closed state to the normally open state.

[0211] The stroke limiting part 283 includes a fixed shaft 2831, a torsion spring 2832 sleeved on the fixed shaft 2831, and a stroke limiting sub-element 2833.

[0212] The stroke limiting sub-element 2833 includes a stroke limiting part 28331 and a power part 28332 having an included angle with the stroke limiting part 28331. The stroke limiting part 28331 is arranged on the side surface of the moving inner shell 22 and corresponds to the inner shell limiting part 224 on the moving inner shell 22, and is used for limiting the moving inner shell 22. The stroke limiting part 28331 is provided with a torsion spring 2832 slot at the side surface away from the moving inner shell 22, one end of the torsion spring 2832 abuts in the torsion spring 2832 slot, and the other end of the torsion spring 2832 abuts on the inner wall of the adapter 2 shell 21, which is used to provide a force to the stroke limiting sub-element 2833. The power part 28332 is arranged corresponding to the end of the stroke linkage part 2822. The stroke linkage part 2822 of the stroke sliding part 282 exerts a force on the supporting power part 28332 of the stroke limiting sub-element 2833, so that the stroke limiting sub-element 2833 can rotate around the fixed shaft 2831.

[0213] Under the action of an external force, the inner shell limiting part 224 of the moving inner shell 22 presses the stroke limiting part 28331 to the side surface of the moving inner shell 22, and the stroke sliding part 2821 passes through the second limit point 28112 from the first limit point 28111 to the third limit point 28113. The third limit point 28113 is the lowermost end of the moving position of the moving inner shell 22. When the stroke sliding part 2821 is at the third limit point 28113, the stroke linkage part 2822 does not contact the power part 28332, and when the lowermost end of the stroke limiting part 28331 is higher than the inner shell limiting part 224, the stroke limiting part 28331 is elastically moved to the upper side of the inner shell limiting part 224 under the action of the torsion spring 2832. After the external force is removed, the switch elastic element 275 pushes the moving inner shell 22 upward, so that the stroke sliding part 2821 slides from the third limit point 28113 to the fourth limit point 28114. At this time, the stroke limiting part 28331 abuts at the inner shell limiting part 224, preventing the moving inner shell 22 from moving upward. At this time, the stroke linkage part 2822 contacts the power part 28332. The adapter 2 is switched from the normally open state to the normally closed state.

[0214] When the inner shell 22 is pressed again under the action of an external force, the stroke sliding part 2821 slides from the fourth limit point 28114 to the fifth limit point 28115, and the stroke linkage part 2822 abuts against the power part 28332. The power part 28332 overcomes the force of the torsion spring 2832 to rotate the lower end of the stroke limit part 28331 away from the moving inner shell 22, so that the stroke limit part 28331 is disengaged from the inner shell limit part 224. Without the blocking of the stroke limit part 28331, the switch elastic member 275 pushes the moving inner shell 22 upward. The adapter 2 is switched from the normally closed state to the normally open state.

[0215] The middle part of the stroke linkage part 2822 protrudes a U-shaped pressing part 2823. The bottom of the moving inner shell 22 extends downward to form an inner shell extension part 222. The inner shell extension part 222 is provided with an inner shell low groove 223 adapted to the stroke sliding part 282. The pressing part 2823 of the stroke sliding part 282 is arranged in the inner shell low groove 223 and can move in the inner shell low groove 223. The movement distance of the stroke sliding part 282 is limited by the inner shell low groove 223. The counterclockwise movement of the stroke sliding part 282 in the stroke groove 2811 is ensured.

[0216] Preferably, the stroke limit block 2812 is hook-shaped, and the limit groove 2813 is the bending part of the stroke limit block 2812.

[0217] Preferably, the lower edge of the stroke groove 2811 protrudes upward to form a detour part 2814, which facilitates the sliding of the stroke sliding part 282 to the limit groove 2813.

[0218] Preferably, the limit groove 2813 extends upward to form a anti-falling part 2815, which prevents the stroke sliding part 282 from sliding out of the limit groove 2813.

[0219] Preferably, the stroke fixing part 281 is further provided with a mounting groove 2816 for facilitating the installation of the stroke sliding part 282. The stroke sliding part 2821 can be installed in the stroke groove 2811 from the mounting groove 2816, which facilitates the installation of the stroke sliding part 282.

The switch structure 27 and the stroke structure 28 are both arranged between the moving inner shell 22 and the inner wall of the adapter 2, the power taking member 25 and the intermediate member 26 are both fixed in the moving inner shell 22, the support member 233 is buckled 5213 at the upper end of the moving inner shell 22, and the unlocking structure 23 is arranged on the upper side of the support member 233. The lower shell 21212 is buckled 5213 connected with the upper shell 211, the lower shell 21212 is enclosed around the periphery of the unlocking structure 23, the unlocking pressing member 234 of the unlocking structure 23 protrudes from the lower shell 21212, and the inner shell pressing member 276 is arranged between the unlocking pressing members 234.

[0221] Preferably, the shell 21 of the adapter 2 further comprises a display structure 29 capable of emitting light. The display structure 29 comprises a fixed plate 291 and a display member 292 on the fixed plate 291, and the display member 292 can be an LED lamp, a light strip or other electrically powered light emitting member. The display member 292 can be electrically connected with the adapter 2, and the display structure 29 can be arranged at the support member 233. When the adapter 2 is powered, the display member 292 is also powered, and the power-on state of the adapter 2 can be displayed.

[0222] Based on the same concept, a display structure can also be arranged in the track 1.

[0223] In the application, the adapter 2 is provided with multiple groups of single-phase power supply. The power that can be transmitted can be obviously increased, and the overload of a single single-phase power supply can be avoided. Thus, stable power supply can be provided for the adapter 2. The electrically conductive structure 5 and the contact point 24 can be matched to quickly electrically connect the cable 3 and the adapter 2, and professional technicians are not required for installation, and errors caused by human installation are reduced.
