Description

Technical Field

[0001] This utility model relates to the field of socket technology, and more specifically, to a track-mounted socket adapter. Background Technology

[0002] Track sockets typically consist of a track and multiple adapters that slide along it. The track can be mounted on a wall or embedded in a table. Any number of adapters can be installed within the track, and each adapter can move along the track to change its position. This allows the adapters to power appliances in multiple locations.

[0003] How to achieve a stable connection and disconnection between the track and the adapter is the key technical point of the track socket. Chinese Patent Announcement No. CN116505317A, Announcement Date July 28, 2023, the utility model name is Track Socket Adapter. This application discloses an adapter, which can make the conductive pins of the two conductive pins extend outward from the two opening slots by rotating the rotating ring. The two conductive pins are inserted into the conductive sleeves on the left and right walls of the track plate. The above adapter has the advantages of easy installation and use. However, there are still the following shortcomings: (1) During the assembly of the adapter, the installation angle of the auxiliary gear is extremely strict. The two auxiliary gears need to be set in a centrally symmetrical manner with respect to the main gear. Otherwise, when the main gear drives the two auxiliary gears to rotate, the rotation angle of the conductive pins connected to the auxiliary gears is inconsistent, and they cannot be stably connected to the track socket. Therefore, the assembly difficulty is increased; (2) When in use, the main gear needs to be rotated to an extreme angle. If the angle of the main gear is not rotated to the correct position, the conductive pins will not be fully unfolded, and they cannot be stably connected to the track socket. Utility Model Content

[0004] This utility model overcomes the following two shortcomings of the prior art: (1) During the assembly of the adapter, the installation angle of the auxiliary gear is extremely strict. The two auxiliary gears need to be set in a centrally symmetrical manner relative to the main gear. Otherwise, when the main gear drives the two auxiliary gears to rotate, the rotating angle of the conductive plug connected to the auxiliary gear is inconsistent, and it cannot be stably connected to the rail socket, which increases the difficulty of assembly; (2) When in use, the main gear needs to be rotated to the extreme angle. If the angle of the main gear is not rotated to the correct position, the conductive plug will not be fully unfolded, and it cannot be stably connected to the rail socket. This utility model provides a rail socket adapter. First, during the assembly process, this application does not need to strictly adjust the angle of the auxiliary gear. It only needs to match the corresponding transmission groove and transmission bar, which has the characteristics of convenient assembly; Second, when in use, the operating ring does not need to be rotated to the extreme angle. After rotating the operating ring to a certain angle, it can automatically reach the extreme angle under the action of the internal switch spring, ensuring that the plug can be connected to the rail socket.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a rail-mounted socket adapter, characterized in that it includes:

[0006] The adapter is provided with a plug-in part, and the two ends of the plug-in part along the length direction are provided with adapter grooves that communicate with the bottom of the adapter.

[0007] Two corresponding conductive pins are rotatably set in two adapter slots; one end of each conductive pin is provided with a conductive insert, and the other end is provided with a transmission slot.

[0008] Rotate the operating ring located on the adapter seat. The inner wall of the operating ring is provided with a transmission bar that mates with the transmission groove.

[0009] In this application, the transmission between the operating ring and the conductive pin is achieved through the cooperation of a transmission bar and a transmission groove. Therefore, compared with the prior art, during assembly, there is no need to strictly adjust the angle of the secondary gear; only the corresponding transmission groove and transmission bar need to be matched. This method is convenient to assemble, improves production efficiency, and reduces production costs. Furthermore, compared with gear transmission, the cooperation of the transmission bar and transmission groove in this application reduces the number of assembled parts, making the overall structure more compact and further reducing production costs. Finally, during use, the operating ring does not need to be rotated to an extreme angle. After rotating the operating ring a certain angle, the internal switching spring automatically reaches the extreme angle, ensuring that the pin can connect with the rail-type socket.

[0010] Preferably, a first spring is provided between the operating ring and the adapter seat; one end of the first spring abuts against the inner side wall of the operating ring, and the other end abuts against the adapter seat.

[0011] The first spring is in a compressed state, and the first spring can push the operating ring to rotate, so that the operating ring is always in an extreme angle state, that is, either the conductive plug is completely retracted into the adapter slot, or the conductive plug is completely perpendicular to the adapter slot.

[0012] Preferably, the maximum rotation angle of the operating ring is A. When the operating ring rotates to the point where the line connecting the two ends of the first spring coincides with the center of the operating ring, the rotation angle of the operating ring is between A / 4 and 3A / 4.

[0013] The balance point angle is within the range of A / 4 to 3A / 4, making it more convenient for users to operate.

[0014] Preferably, the adapter base has an inner seat with two adapter blocks on it. The two adapter blocks mate with two adapter slots respectively, and the adapter blocks and adapter slots mate to form a plug-in gap. The conductive insert retracts into the plug-in gap.

[0015] The fit between the adapter block and the adapter slot facilitates the positioning and installation of the inner seat. The adapter block can also fit with the plug-in part to form an integral plate-like structure.

[0016] Preferably, the adapter is provided with several fixing posts, which are located on the end face away from the plug-in part. The edge of the inner seat is provided with a limiting arc, the shape of which matches the outer wall of the fixing post.

[0017] The limiting edge arc cooperates with the outer wall of the fixed column to restrict the rotation of the inner seat within the adapter seat.

[0018] Preferably, the outer wall of the fixing post is provided with a fixing protrusion, the thickness of which gradually increases towards the adapter seat, forming an inclined surface that is smoothly connected to the outer wall of the fixing post.

[0019] The fixed protrusion acts as a limiting block, making it easy to install the inner seat into the adapter seat, eliminating the need for bolts and other structures.

[0020] Preferably, the device also includes a plug panel, which is located on the side of the operating ring away from the adapter seat. The plug panel has a plug post that mates with a fixing post. The top of the fixing post has a fixing hole, and the plug post abuts against the fixing hole.

[0021] After the screw passes through the fixing post, it connects to the threaded hole, fixing the fixing post and the insert post together. The insert panel and the adapter base form an integral fixed structure, while the operating ring can rotate between the insert panel and the adapter base.

[0022] Preferably, the operating ring includes a rotating ring and a sleeve ring connected to each other; the sleeve ring is rotatably engaged with the adapter seat.

[0023] The adapter is fitted onto the outside of the socket ring. Rotating the rotating ring by hand will cause the socket ring to rotate within the adapter.

[0024] Preferably, a locking key is provided in the adapter, the locking key including a pressing part and a hook part;

[0025] A locking hole is provided through the side wall of the adapter, and a locking groove is provided in the middle of the plug-in part. The top of the locking groove is connected to the adapter, and the side wall of the locking groove is provided with a side opening that penetrates the side wall of the plug-in part.

[0026] The hook part is located in the lock groove and protrudes from the side opening, while the pressing part is located in the lock hole;

[0027] The adapter is equipped with a second spring that pushes the locking key toward the outer wall of the adapter.

[0028] Under the action of the second spring, the hook portion of the locking key always protrudes from the end face of the plug. When the pressing part is pressed by hand, the locking key moves inward against the force of the second spring, and the hook portion retracts into the locking groove. Therefore, the above-described design allows for convenient connection of this application to a rail-mounted socket.

[0029] Preferably, the device also includes a sleeve on the inner seat, the sleeve having an elastic clip, and the conductive pin having a conductive head, with the elastic clip clamping the conductive head.

[0030] The arc-shaped grooves on the two elastic clips engage to clamp the conductive head. This ensures that the elastic clips maintain close contact with the conductive head even as the conductive pin rotates.

[0031] Compared with existing technologies, the advantages of this utility model are as follows: The transmission bar and transmission groove work together to achieve transmission between the operating ring and the conductive pin. Therefore, compared with existing technologies, during assembly, there is no need to strictly adjust the angle of the secondary gear; only the corresponding transmission groove and transmission bar need to be matched, resulting in convenient assembly, improved production efficiency, and reduced production costs. Secondly, compared with gear transmission, the transmission bar and transmission groove in this application reduce the number of assembled parts, making the overall structure more compact and further reducing production costs. Finally, during use, the operating ring does not need to be rotated to an extreme angle; after rotating the operating ring a certain angle, the internal switch spring automatically reaches the extreme angle, ensuring that the pin can connect with the rail-type socket.

[0046] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings:

[0047] Example 1: Refer to Figures 1 to 5 As shown, a rail-mounted socket adapter is characterized by comprising: an adapter base 1, an operating ring 2 that mates with the adapter base 1, and a conductive component disposed within the adapter base 1.

[0048] The bottom of the adapter 1 is provided with a plug-in part 11, and both ends of the plug-in part 11 in the length direction are provided with adapter grooves 111 that communicate with the bottom of the adapter 1.

[0049] The conductive component includes two conductive pins 3 that are rotatably disposed in two adapter slots 111; one end of the conductive pin 3 is provided with a conductive insert 31, and the other end is provided with a transmission slot 32, and the conductive pin 3 is disposed in the adapter slot 111.

[0050] The bottom of the operating ring 2 is engaged with the adapter 1 and can rotate relative to the adapter 1. The inner side wall of the operating ring 2 is provided with a transmission bar 21 that engages with the transmission groove 32.

[0051] Rotate the operating ring 2, which drives the transmission bar 21 to move. The transmission bar 21 drives the conductive pin 3 to rotate through the transmission groove 32, controlling the conductive insert 31 to extend or retract into the adapter groove 111.

[0052] The plug-in portion 11 is a plate-shaped structure protruding from the bottom of the adapter base 1. Adapter grooves 111 are symmetrically arranged at both ends along the length of the plug-in portion 11. A middle plate 112 is located in the middle of the plug-in portion 11, and the adapter grooves 111 are symmetrically arranged at both ends of the middle plate 112. The adapter grooves 111 not only penetrate the plug-in portion 11, but their tops also penetrate the bottom of the adapter base 1.

[0053] Two conductive pins 3 are provided. The conductive pins 3 are rotatably disposed within the adapter base 1. The conductive pins 3 are inserted into the adapter base 1, with one part located in the adapter groove 111 and the other part located within the adapter base 1. The conductive insert 31 is disposed at one end near the adapter groove 111, while the transmission groove 32 is disposed at one end near the adapter base 1.

[0054] Two transmission bars 21 are provided on the inner wall of the operating ring 2, which cooperate with the conductive pins 3. The two transmission bars 21 are adapted to the transmission grooves 32 on the two conductive pins 3. The transmission bars 21 protrude from the inner wall of the operating ring 2, and the length of the transmission bars 21 from the inner wall of the operating ring 2 is adapted to the length of the transmission grooves 32.

[0055] In this embodiment, rotating the operating ring 2 clockwise causes the transmission bar 21 on the inner wall of the operating ring 2 to drive the transmission groove 32 to rotate around the conductive pin 3. The conductive pin 3 then drives the conductive insert 31 at its bottom to rotate, causing the conductive insert 31 to rotate out of the adapter groove 111. When the operating ring 2 rotates to its maximum angle, the conductive insert 31 is perpendicular to the plug-in part 11, and at this time, the conductive insert 31 can maintain a energized state with the track-type socket. Afterward, rotating counterclockwise causes the conductive insert 31 to rotate to the opposite angle and reset, returning to the adapter groove 111.

[0056] The width of the conductive insert 31 is not greater than the thickness of the plug portion 11, so that the conductive insert 31 can be completely retracted into the adapter groove 111.

[0057] In one embodiment, a first spring 4 in a compressed state is provided inside the adapter 1. One end of the first spring 4 abuts against the inner wall of the operating ring 2, and the other end abuts against the abutment member 12 fixed to the adapter 1. The first spring 4 can push the operating ring 2 to rotate, so that the operating ring 2 is always in an extreme angle state, that is, either the conductive insert 31 is completely retracted into the adapter groove 111, or the conductive insert 31 is completely perpendicular to the adapter groove 111.

[0058] When the operating ring 2 rotates, the equilibrium angle is reached when the line connecting the two ends of the first spring 4 coincides with the center of the operating ring 2. During the rotation of the operating ring 2, before reaching the equilibrium angle, the first spring 4 is continuously compressed. When the ring reaches the equilibrium angle, the first spring 4 is compressed to its maximum. After exceeding the equilibrium angle, the first spring 4 extends, thus pushing the operating ring 2 to rotate to its extreme angle. Therefore, as long as the operating ring 2 is rotated beyond the equilibrium angle and then released, it will automatically rotate to the extreme angle under the action of the first spring 4. It is not necessary to manually rotate the operating ring 2 to the extreme angle.

[0059] The maximum rotation angle of the operating ring 2 is A. When the line connecting the two ends of the first spring 4 coincides with the center of the operating ring 2, the angle at which the operating ring 2 has rotated is within the range of A / 4 to 3A / 4. The equilibrium point angle is within the range of A / 4 to 3A / 4, which facilitates user operation. In this embodiment, the maximum rotation angle A of the operating ring 2 is between 25° and 40°.

[0060] Preferably, A in this embodiment is 27° to 29°. In this embodiment, when the operating ring 2 rotates to 14°, the line connecting the two ends of the first spring 4 coincides with the center of the operating ring 2. When the operating ring 2 rotates beyond 14°, the operating ring 2 will automatically rotate to its extreme state under the force of the first spring 4.

[0061] In one embodiment, the operating ring 2 includes a rotating ring 22 and a sleeve ring 23, the diameter of which is smaller than the diameter of the rotating ring 22; the sleeve ring 23 is rotatably mounted on the adapter seat 1. A transmission bar 21 is disposed on the inner sidewall of the sleeve ring 23.

[0062] The adapter seat 1 is fitted onto the outer side of the sleeve ring 23. Rotating the rotating ring 22 by hand causes the sleeve ring 23 to rotate within the adapter seat 1. Furthermore, in this application, the inner sidewall of the adapter seat 1 is provided with several sidewall ribs 13 arranged along its axial direction, and the sidewall ribs 13 are located on the outer sidewall of the sleeve ring 23. The sidewall ribs 13 reduce the contact area with the outer sidewall of the sleeve ring 23, thereby reducing the frictional force experienced by the sleeve ring 23 during rotation, making it easier for the operating ring 2 to rotate.

[0063] In one embodiment, the side of the operating ring 2 away from the adapter 1 is provided with a plug panel 5 that mates with it, and the operating ring 2 can also rotate relative to the plug panel 5. The plug panel 5 is provided with a plurality of sockets 51 that mate with the plug, and in this embodiment, there are five sockets 51.

[0064] On the end face of the adapter 1 away from the insertion part 11, there are several fixing posts 14. The insertion panel 5 has insertion face posts 52 that mate with the fixing posts 14. The top of each fixing post 14 has a fixing hole 141, and the insertion face post 52 abuts against the fixing hole 141. A threaded hole is located at the center of each insertion face post 52. A screw 142 passes through the fixing post 14 and is threaded into the threaded hole, thus fixing the fixing post 14 and the insertion face post 52 together. The insertion panel 5 and the adapter 1 form an integral fixed structure, while the operating ring 2 can rotate between the insertion panel 5 and the adapter 1.

[0065] In one embodiment, an inner seat 6 is provided within the adapter seat 1 to mate with it. The bottom of the inner seat 6 is provided with an adapter block 61 that mates with two adapter slots 111. The adapter block 61 and the adapter slots 111 mate to form a plug-in gap, and the conductive insert 31 retracts into the plug-in gap. The mating of the adapter block 61 and the adapter slots 111 facilitates the positioning and installation of the inner seat 6. The adapter block 61 can also mate with the plug-in portion 11 to form an integral plate-like structure.

[0066] The inner seat 6 has several limiting arcs 62 on its edge that mate with the outer wall of the fixed post 14. The shape of the limiting arcs 62 mates with the outer wall of the fixed post 14, which can restrict the rotation of the inner seat 6 within the adapter seat 1.

[0067] In addition, a fixing protrusion 143 is provided on the outer wall of the fixing post 14. The thickness of the fixing protrusion 143 gradually increases towards the adapter seat 1, forming an inclined surface 144 on the outer wall of the fixing protrusion 143 that connects with the outer wall of the fixing post 14. A gap is provided between the fixing protrusion 143 and the bottom of the adapter seat 1. When installing the inner seat 6, the limiting edge arc 62 slides along the outer side of the fixing post 14. When it is about to reach the bottom of the fixing post 14, the limiting edge arc 62 slides along the outer wall of the fixing protrusion 143 and finally moves to the bottom of the adapter seat 1. The fixing protrusion 143 plays a limiting role for the inner seat 6. The fixing protrusion 143 is equivalent to a limiting block, which makes it easy to install the inner seat 6 into the adapter seat 1, eliminating the need for bolts or other structures.

[0068] A socket groove 63 for mounting a socket 64 is provided on the end face of the inner seat 6 away from the adapter block 61. The socket 64 can be directly inserted into the socket groove 63, facilitating the installation of the socket 64. In this embodiment, two sockets 64 are provided, and the two sockets 64 are electrically connected to two conductive pins 3 respectively. The two sockets 64 correspond to the L and N poles of the power supply.

[0069] The socket 64 is provided with an elastic clamping groove 641 that mates with the plug.

[0070] The socket 64 is provided with an elastic clip 642, and the top of the conductive pin 3 is provided with a conductive head 33. The elastic clip 642 is clamped on the conductive head 33. Each socket 64 is provided with two elastic clips 642, which are symmetrically arranged. The elastic clips 642 are provided with arc-shaped grooves 643, and the arc-shaped grooves 643 on the two elastic clips 642 cooperate to clamp the conductive head 33.

[0071] In this embodiment, the conductive head 33 and the conductive insert 31 are integrally formed. This allows the track-type socket to be electrically connected via the conductive insert 31, the conductive head 33, and the socket 64.

[0072] In one embodiment, a mounting bracket 65 is provided on the side of the inner seat 6 away from the adapter seat 1. The mounting bracket 65 has a through groove 651 corresponding to the elastic clamping groove 641. A protective door 66 is slidably disposed inside the mounting bracket 65. Protective springs 661 are provided on both sides of the protective door 66, and the protective springs 661 abut against the outer side of the protective door 66 and the inner side of the mounting bracket 65. The protective door 66 has an inclined protective surface 662 corresponding to the plug sleeve 64. The protective springs 661 abut against both sides of the protective door 66, so that when the plug is inserted, the conductive piece on the plug acts on the inclined protective surface 662, allowing the protective door 66 to move relative to the mounting bracket 65. This allows the conductive piece to engage with the elastic clamping groove 641 on the plug sleeve 64, and the elastic clamping groove 641 clamps the conductive piece on both sides, realizing the electrical connection between the conductive piece and the elastic clamping groove 641.

[0073] In this application, the transmission between the operating ring 2 and the conductive pin 3 is achieved through the cooperation of the transmission bar 21 and the transmission groove 32. Therefore, compared with the prior art, during the assembly process, it is not necessary to strictly adjust the angle of the secondary gear; it is only necessary to align the corresponding transmission groove 32 and the transmission bar 21. This method is convenient to assemble, improves production efficiency, and reduces production costs. Furthermore, compared with gear transmission, the cooperation between the transmission bar 21 and the transmission groove 32 in this application reduces the number of assembled parts, making the overall structure more compact and further reducing production costs. Finally, during use, the operating ring 2 does not need to be rotated to an extreme angle. After rotating the operating ring 2 by a certain angle, the first spring 4 inside it will automatically reach the extreme angle, ensuring that the conductive pin 31 can connect with the rail-type socket.

[0074] Example 2: Refer to Figures 1 to 5 As shown, this embodiment is similar in structure to that in embodiment 1, except that it also includes a locking key 7, which includes a pressing part 71 and a hook part 72; the extension line of the length direction of the locking key 7 coincides with the center of the adapter seat 1.

[0075] A locking hole 15 is provided through the side wall of the adapter 1, and a locking groove 113 is provided in the middle of the plug-in part 11. The locking groove 113 is provided on the middle plate 112, and the top of the locking groove 113 is connected to the adapter 1. The side wall of the locking groove 113 is provided with a side opening that penetrates the side wall of the plug-in part 11.

[0076] The hook part 72 is provided in the lock groove 113 and protrudes from the side opening accordingly, and the pressing part 71 is provided in the lock hole 15;

[0077] The adapter 1 is equipped with a second spring 73 that pushes the locking key 7 toward the outer wall of the adapter 1.

[0078] Under the force of the second spring 73, the locking key 7 and the hook portion 72 always protrude from the end face of the plug portion 11. When the pressing part 71 is pressed by hand, the locking key 7 moves inward against the force of the second spring 73, and the hook portion 72 retracts into the locking groove 113. Therefore, the above-described configuration allows for convenient connection of this application to a rail-mounted socket.

[0079] Example 3: Reference Figures 1 to 6 As shown, this embodiment is similar in structure to that in embodiment 1 or embodiment 2, except that it also includes a grounding pin 8, a grounding hole 114 is provided in the plug part 11, the grounding hole 114 is provided to penetrate the middle plate 112, and a grounding clamping groove 81 composed of elastic sheets is provided on the top of the grounding pin 8.

[0080] Through the above structure, the grounding pin 8 is connected to the rail-mounted socket. The grounding plug is inserted into the grounding clamp 81 to realize the grounding function of the grounding plug.
