Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to adapters and track sockets having the same. Background Technology

[0002] A track-mounted socket includes a track plate and several adapters slidably mounted thereon. The track plate has conductive sleeves electrically connected to the power supply line. The adapters have conductive prongs and sockets. When using the track-mounted socket, the conductive prongs of the adapters are inserted into the conductive sleeves of the track plate and make electrical contact with the sleeves. Thus, when an appliance is plugged into the socket of the adapter, the appliance draws power from the adapter.

[0003] In addition, the adapter is also snapped into the track plate by a latch, and the snap-fit ​​structure of the adapter is also a key technical feature of various track-type socket products. Summary of the Invention

[0004] In view of this, the present invention provides an adapter and a rail-mounted socket having the same, for making it easier to install the adapter onto the rail plate of the rail-mounted socket.

[0005] In a first aspect, the adapter for the rail-mounted socket provided by the present invention includes a base and a pair of locking blocks, an adjusting ring, and a transmission mechanism disposed on the base. The base has a limiting frame extending away from its bottom surface, and a first window on the limiting frame connects opposite sides of the limiting frame. Each locking block has a pivot at one end and a latch at the other end; two pivots are disposed parallel to the bottom surface of the base and the pair of locking blocks are disposed opposite each other on the base, with the two latches respectively facing opposite sides of the first window. The adjusting ring is disposed on the top surface of the base and is axially movable relative to the base. The transmission mechanism is disposed between the adjusting ring and the pair of locking blocks and is configured to drive the pair of locking blocks to open and close about their respective pivots when the adjusting ring moves axially relative to the base.

[0006] As can be seen from the above scheme, during the use of the track-mounted socket, before the adapter is installed onto the track plate, the adjusting ring can be positioned in a first axial position relative to the base, causing the two locking blocks to retract synchronously into the inner side of the first window. After the limiting bracket on the adapter's base is inserted into the limiting opening of the track plate, the adjusting ring can move relative to the base to a second axial position, causing the two locking blocks to extend synchronously from both sides of the limiting bracket to engage with the inner walls of both sides of the limiting opening. In this way, the adapter can be installed on the track plate more conveniently and reliably.

[0007] For example, the aforementioned transmission mechanism can be a gear transmission mechanism, a crank-connecting rod transmission mechanism, etc. In a preferred embodiment, the transmission mechanism may include a lifting member and a sliding member. Optionally, the pair of locking blocks have mutually cooperating meshing portions or rolling portions formed around their respective axes of rotation, so as to allow the pair of locking blocks to swing synchronously around their respective axes of rotation.

[0008] A lifting member is connected to the adjusting ring so that it can move axially relative to the base together with the adjusting ring. For example, the lifting member has at least one concave ring portion, and the inner peripheral wall of the adjusting ring has a convex ring portion that rotates and limits the concave ring portion, so that the lifting member and the adjusting ring are rotated and limited. Alternatively, the lifting member may have a protrusion that engages with a concave portion on the inner wall of the adjusting ring to achieve the purpose of the lifting member moving axially relative to the base together with the adjusting ring. Preferably, the lifting member also has a limiting rod extending toward the base, and the base has a limiting groove extending into the interior of the limiting frame. The limiting rod slides into the limiting groove to maintain the axial movement of the lifting member relative to the base. Similarly, a corresponding groove may be provided on the lifting member to engage with a rod provided on the base to maintain the axial movement of the lifting member relative to the base.

[0009] The sliding member may have a limiting inclined surface that slides in conjunction with the lifting member. When the lifting member moves axially, the sliding member slides on the base toward or away from the locking blocks to drive the pair of locking blocks to open and close. Preferably, the lifting member may also have a limiting platform extending toward the limiting inclined surface, which is configured to slide in conjunction with the limiting inclined surface of the sliding member. In another optional embodiment, the lifting member may be omitted, and a boss similar in function to the limiting platform may be directly provided on the adjusting ring to slide in conjunction with the slider. When the adjusting ring moves axially relative to the base, the sliding member moves along the base.

[0010] In one alternative embodiment, the transmission mechanism further includes a torsion spring disposed between the slider and the locking blocks to drive the pair of locking blocks to open and close during the sliding process.

[0011] For example, the torsion spring includes two coaxially arranged helical rings, one end of which extends outward and connects to both ends of a crossbar, the crossbar being parallel to the axis of the torsion spring; the other ends of the two helical rings each extend outward and form a support leg. The crossbar presses against the side of the sliding member facing away from the limiting inclined surface, and the two supports are respectively disposed in one of the two locking blocks, such that when the sliding member slides towards the locking block, the two locking blocks close under the elastic deformation of the torsion spring; and when the sliding member slides away from the locking block, the two locking blocks open under the elastic restoring force of the torsion spring.

[0012] In the above technical solution, when the adjusting ring is lifted relative to the base, the sliding member moves towards the pair of locking blocks, causing the torsion spring to compress and, through its two legs, to close the pair of locking blocks. This allows the limiting bracket of the adapter base to extend into the track plate, or the adapter to be removed from the track plate. Conversely, when the adjusting ring is lowered relative to the base, the sliding member moves away from the pair of locking blocks, causing the torsion spring to relax and, through its two legs, to open the pair of locking blocks. Thus, with the limiting bracket of the adapter base inserted into the track plate, the pair of locking blocks can be engaged with the inner walls of the limiting opening on the track plate.

[0013] It should be noted that by changing the form of the torsion spring, it is also possible to make the locking block lock on both sides of the inner wall of the limiting port of the track plate when the adjusting ring is lifted relative to the base, and to make the adapter remove from the track plate or to make the limiting bracket of the adapter extend into the track plate when the adjusting ring is lowered relative to the base.

[0014] In a preferred embodiment of the adapter described above, the lower end of the slider has a sliding post extending along its sliding direction. The adapter also includes an inner seat disposed on the base with its bottom end extending into the limiting frame. The inner seat has mounting slots for the pair of locking blocks and a sliding groove for the sliding post to slide on. Thus, by providing this inner seat, the pair of locking blocks can be more easily mounted on the base, and the sliding of the slider can be limited. It should be noted that although this embodiment uses the inner seat to limit the sliding of the slider, without the inner seat, a corresponding sliding groove can also be directly provided on the base to cooperate with the sliding post of the slider for limiting.

[0015] In a preferred embodiment of the adapter described above, the adapter further includes a central seat and at least one elastic element. The central seat is connected to the top surface of the base and located inside the adjusting ring, with an arc-shaped cavity formed on its outer side. A mounting bracket is provided on the inner wall of the adjusting ring, and the mounting bracket is located within the arc-shaped cavity. The elastic element is disposed between the mounting bracket and the top surface of the arc-shaped cavity to press the adjusting ring against the base axially, thereby opening the pair of locking blocks. Thus, in normal operation, the elastic element presses the adjusting ring against the base, allowing the adapter to be held securely against the track plate by the locking blocks, resulting in a more reliable connection between the adapter and the track plate.

[0016] For example, the mounting bracket may have at least one positioning post and at least one connecting hole, both facing the top surface of the arc-shaped cavity. The elastic element is a spring, which is sleeved on the positioning post and rests between the mounting bracket and the top surface of the arc-shaped cavity. The upper end of the spring is bent into a connecting rod parallel to the axis, and the connecting rod is inserted into the connecting hole. Thus, when the adjusting ring moves axially relative to the base, the positioning post can position the spring, making the spring's setting more reliable. Simultaneously, the connecting rod at one end of the spring engages with the connecting hole on the mounting bracket, ensuring that the spring does not misalign and can extend and retract normally along its own axis when the adjusting ring rotates relative to the base.

[0017] In a preferred embodiment of the adapter provided in the above embodiments, the limiting frame is further provided with a second window, which is spaced apart from the first window in the length direction extending along the bottom surface of the base. The adapter also includes two conductive pins, each conductive pin including a conductive shaft and a conductive insert extending from the side wall of the conductive shaft; one conductive insert is disposed in the first window, and the other conductive insert is disposed in the second window, and one end of each of the two conductive shafts extends from the top surface of the base. The adjusting ring is also rotatably disposed coaxially with respect to the base, so as to drive a transmission component to make the two conductive inserts swing around their respective corresponding conductive shafts, and to make the two conductive inserts extend in opposite directions relative to the limiting frame. Thus, in addition to controlling the locking block by moving axially relative to the base to lock the adapter onto the track plate, the adjusting ring can also control the conductive inserts of the two conductive pins to rotate by rotating relative to the base, thereby completing the electrical connection between the adapter and the track plate.

[0018] To facilitate understanding of the adapter's structure by technicians, a track plate is used as an example. For instance, the track plate contains an installation space. A conductive sleeve is provided on both the left and right walls of this space, and the top wall of the installation space has a limiting opening for the adapter's retaining frame to extend into and slide. Before the adapter is installed on the track plate, rotating the adjusting ring allows the conductive tabs to be positioned inside the retaining frame, where the ends of the two conductive tabs can face each other and be aligned. After the adapter is installed on the track plate, rotating the adjusting ring synchronously drives two conductive pins to rotate, causing one conductive tab to extend from one window and insert into the conductive sleeve on the left wall of the track plate, while the other conductive tab extends from the other side of the other window and inserts into the conductive sleeve on the right wall of the track plate. When the two conductive tabs extend in opposite directions from opposite sides of the retaining frame, the adapter is electrically connected to the track plate. Simultaneously, the insertion of the conductive tabs into the conductive sleeves ensures a secure installation of the adapter on the track plate.

[0019] In a preferred embodiment, the transmission assembly may include a main gear and two auxiliary gears, all disposed on the top surface of the base. The two auxiliary gears are respectively connected to a conductive shaft, and the main gear meshes with the two auxiliary gears for transmission. An adjusting ring is disposed on the top surface of the base and connected to the main gear, so as to drive the main gear to rotate coaxially, thereby causing the two conductive inserts to swing synchronously, allowing the ends of the two conductive inserts to extend in opposite directions from their respective windows. A middle seat is connected to the top surface of the base and located inside the adjusting ring. The two conductive shafts extend out of the middle seat, which is also configured to limit the two auxiliary gears axially.

[0020] It should be noted that, in another embodiment, the transmission assembly may further include a cam, wherein when the small diameter portions of the cam on both sides are aligned with the two conductive shafts, the corresponding two conductive inserts remain retracted into the corresponding first window or second window; when the large diameter portions of the cam on both sides are aligned with the two conductive shafts, the cam drives the two conductive inserts to extend in opposite directions relative to the limiting frame.

[0021] Secondly, in the rail-type socket provided by the present invention, the rail-type socket includes a rail plate and an adapter as described in any of the above embodiments. The rail plate forms a limiting opening into which a limiting bracket of the adapter extends, and a pair of locking blocks of the adapter can be engaged with the inner walls on both sides of the limiting opening in the extended state.

[0045] To make the objectives, technical solutions, and advantages of the present invention clearer, the following embodiments are provided to further illustrate the present invention in detail.

[0046] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0047] from Figure 1 As can be seen, the track-type socket provided in this embodiment includes a track plate 9 and an adapter 10 that can be connected to the track plate 9. An installation space 91 is formed inside the track plate 9. A conductive socket 92 is provided on the left and right walls of the installation space 91, and a limiting opening 911 is formed on the top wall of the installation space 91.

[0048] Continue to refer to Figure 1 The adapter 10 includes a base 1 and an adjusting ring 3 rotatably disposed relative to the base 1. The adjusting ring 3 can also move axially along the base 1, while the top cover 13 with a socket is fixedly connected to the base 1. A limiting bracket 11 on the base 1 extends into the installation space 91 through a limiting opening 911 on the track plate 9. After the adapter 10 is installed on the track plate 9, rotating the adjusting ring 3 causes a conductive insert 62 to extend from both the left and right sides of the limiting bracket 11. One conductive insert 62 extends from one side of the first window 111, and the other extends from the other side of the second window 112, meaning the two conductive inserts 62 extend in opposite directions relative to the limiting bracket 11. Simultaneously, the two conductive inserts 62 can be inserted into and conduct electricity to the conductive sleeves 92 on the left and right walls of the installation space 91, respectively, so that power can be drawn when the plug of an appliance is inserted into the socket on the top cover 13.

[0049] In addition, two locking blocks 2 are provided in the first window 111 of the adapter 10. When the adapter 10 is installed on the track plate 9, the axial movement of the adjusting ring 3 relative to the base 1 will cause the pair of locking blocks 2 of the adapter 10 to open and lock into the inner walls on both sides of the limiting port 911.

[0050] The above description provides an exemplary explanation of the use of the rail-mounted socket in this embodiment. The following section will describe in detail the detailed structure of the adapter 10 and the advantages of using the rail-mounted socket with the adapter 10.

[0051] Combination Figure 1 and Figure 2 In the adapter 10, the base 1 has a limiting frame 11 extending away from its bottom surface. The limiting frame 11 has a first window 111 and a second window 112 spaced apart along the length direction extending along the bottom surface of the base 1, and the first window 111 connects the opposite sides of the limiting frame 11.

[0052] The adapter 10 also includes two conductive pins 6, each of which includes a conductive shaft 61 and a conductive tab 62 extending from the side wall of the conductive shaft 61. One conductive tab 62 is disposed in the first window 111, and the other conductive tab 62 is disposed in the second window 112, with one end of each conductive shaft 61 extending from the top surface of the base 1.

[0053] The adjusting ring 3 is rotatably set coaxially with respect to the base 1, and can drive a transmission component to make the two conductive inserts 62 swing around their respective conductive shafts 61, so that the two conductive inserts 62 can extend in opposite directions relative to the limiting frame 11.

[0054] Reference Figure 2 In a preferred embodiment, the transmission assembly may include a main gear 71 and two auxiliary gears 72, both of which are disposed on the top surface of the base 1. The two auxiliary gears 72 are respectively connected to a conductive shaft 61, and the main gear 71 meshes with the two auxiliary gears 72 for transmission. An adjusting ring 3 is disposed on the top surface of the base 1 and connected to the main gear 71, so as to drive the main gear 71 to rotate coaxially, thereby causing the two conductive inserts 62 to swing synchronously, and allowing the ends of the two conductive inserts 62 to extend in opposite directions from their respective windows.

[0055] Preferably, the middle seat 5 is connected to the top surface of the base 1 and located inside the adjusting ring 3. The middle seat 5 can limit the two auxiliary gears 72 in the axial direction of the auxiliary gears 72. In addition, a plurality of electrical connectors 611 are arranged above the middle seat 5 for electrical connection with an external plug. The conductive shafts 61 of the two conductive pins 6 also pass through the middle seat 5 and are rotatably connected to an electrical connector 611 to achieve conductivity.

[0056] It should be noted that the transmission assembly capable of controlling the conductive pin 61 in this embodiment is not limited to this. For example, in another embodiment, the transmission assembly may also include a cam, wherein when the small diameter portions of the cam on both sides are aligned with the two conductive shafts 61, the corresponding two conductive inserts 62 remain retracted into the corresponding first window 111 or second window 112; when the large diameter portions of the cam on both sides are aligned with the two conductive shafts 61, the cam drives the two conductive inserts 62 to extend in opposite directions relative to the limiting frame 11.

[0057] Before the adapter 10 is installed on the track plate 9, the adjusting ring 3 can be rotated to position the conductive insert 62 inside the limiting frame 11. At this time, the ends of the two conductive inserts 62 can face each other, and the two conductive inserts 62 can also be on the same straight line. After the adapter 10 is installed on the track plate 9, the rotation of the adjusting ring 3 can synchronously drive the two conductive pins 6 to rotate, so that one conductive insert 62 extends out from one window and inserts into the conductive sleeve 92 on the left side wall of the track plate 9, while the other conductive insert 62 extends out from the other side of the other window and inserts into the conductive sleeve 92 on the right side wall of the track plate 9. When the two conductive inserts 62 extend out from the two sides of the limiting frame 11 in opposite directions, the adapter 10 is electrically connected to the track plate 9. At the same time, due to the insertion of the conductive inserts 62 and the conductive sleeves 92, the adapter 10 can be securely installed on the track plate 9.

[0058] Combination Figures 1 to 3 In the track-type socket adapter 10 provided in this embodiment, the base 1 of the adapter 10 is further provided with a pair of locking blocks 2 and a set of transmission mechanisms 4. Each locking block 2 has a rotating shaft 21 at one end and a latch 22 at the other end. The two rotating shafts 21 are arranged parallel to the bottom surface of the base 1, and the pair of locking blocks 2 are arranged opposite each other on the base 1, with the two latches 22 respectively facing opposite sides of the first window 111. The transmission mechanism 4 is disposed between the adjusting ring 3 and the pair of locking blocks 2, and the transmission mechanism 4 is configured to drive the pair of locking blocks 2 to swing around their respective rotating shafts 21 when the adjusting ring 3 moves axially relative to the base 1. For example, the transmission mechanism 4 can be a gear transmission mechanism 4, a crank-connecting rod transmission mechanism 4, etc. Optionally, the pair of locking blocks 2 have mutually cooperating meshing parts or rolling parts around their respective rotating shafts 21 so that the pair of locking blocks 2 swing synchronously around their respective rotating shafts 21.

[0059] As can be seen from the above scheme, during the use of the track socket, before the adapter 10 is installed on the track plate 9, the adjusting ring 3 can be located in the first axial position relative to the base 1, and the two locking blocks 2 can be synchronously retracted into the inner side of the first window 111 through the transmission mechanism 4; after the limiting bracket 11 on the base 1 of the adapter 10 is inserted into the limiting port 911 of the track plate 9, the adjusting ring 3 can be moved to the second axial position relative to the base 1, and the two locking blocks 2 can be synchronously extended from both sides of the limiting bracket 11 through the transmission mechanism 4 to be engaged with the inner walls of both sides of the limiting port 911, so that the adapter 10 can be installed on the track plate 9 more conveniently and reliably.

[0060] Thus, in addition to controlling the rotation of the conductive inserts 62 of the two conductive pins 6 relative to the base 1 to complete the electrical connection between the adapter 10 and the track plate 9, the aforementioned adjusting ring 3 can also control the locking block 2 by moving axially relative to the base 1 to lock the adapter 10 onto the track plate 9.

[0061] In a preferred embodiment, refer to Figure 3 and Figure 4 The transmission mechanism 4 may further include a lifting member 41 and a sliding member 42. The lifting member 41 is connected to the adjusting ring 3 and can move axially relative to the base 1 together with the adjusting ring 3. The sliding member 42 may have a limiting inclined surface 421 that slides in cooperation with the lifting member 41, and when the lifting member 41 moves axially, the sliding member 42 slides on the base 1 in a direction closer to or further away from the locking block 2, thereby driving the pair of locking blocks 2 to open and close.

[0062] For example, the lifting member 41 has at least one concave ring portion 411, and the inner peripheral wall of the adjusting ring 3 has a convex ring portion 32 that rotates and limits the concave ring portion 411, so that the lifting member 41 and the adjusting ring 3 are rotated and limited together, so that the lifting member 41 can move axially relative to the base 1 together with the adjusting ring 3, while keeping the lifting member 41 stationary relative to the base 1 when the adjusting ring 3 rotates relative to the base 1. Alternatively, the lifting member 41 may have a protrusion that engages with the concave portion on the inner wall of the adjusting ring 3 to achieve the purpose of the lifting member 41 moving axially relative to the base 1 together with the adjusting ring 3.

[0063] Preferably, the lifting member 41 may also have a limiting rod 413 extending toward the base 1. The base 1 is provided with a limiting groove 12 extending into the limiting frame 11. The limiting rod 413 and the limiting groove 12 are slidably engaged to maintain the axial movement of the lifting member 41 relative to the base 1. Similarly, a corresponding groove may be provided on the lifting member 41 to engage with the rod provided on the base 1 to maintain the axial movement of the lifting member 41 relative to the base 1.

[0064] Preferably, the lifting member 41 may also have a limiting platform 412 extending toward the limiting inclined surface 421, the limiting platform 412 being configured to slide in engagement with the limiting inclined surface 421 of the sliding member 42. In another optional embodiment, the lifting member 41 may be omitted, and a boss similar in function to the limiting platform 412 may be provided directly on the adjusting ring 3 to slide in engagement with the slider, and when the adjusting ring 3 is moved axially relative to the base 1, the sliding member 42 slides along the base 1.

[0065] In one alternative implementation, refer to Figure 4 The aforementioned transmission mechanism 4 may also include a torsion spring 43, which is disposed between the sliding member 42 and the locking block 2 to drive a pair of locking blocks 2 to open and close during the sliding process of the sliding member 42.

[0066] For example, the torsion spring 43 includes two coaxially arranged helical rings 431, with one end of each helical ring 431 extending outward and connecting to both ends of a crossbar 432, which is parallel to the axis of the torsion spring 43. The other ends of both helical rings 431 extend outward and each form a support leg 433. The crossbar 432 presses against one side of the sliding member 42 away from the limiting inclined surface 421. The two supports 433 are respectively disposed in one of the two locking blocks 2, such that when the sliding member 42 slides towards the locking block 2, the two locking blocks 2 close under the elastic deformation of the torsion spring 43; and when the sliding member 42 slides away from the locking block 2, the two locking blocks 2 open under the elastic restoring force of the torsion spring 43.

[0067] In the above technical solution, when the adjusting ring 3 is lifted relative to the base 1, the sliding member 42 moves towards the pair of locking blocks 2, causing the torsion spring 43 to compress and drive the pair of locking blocks 2 to close via its two support legs 433. This allows the limiting frame 11 of the adapter 10 base 1 to extend into the track plate 9, or the adapter 10 to be removed from the track plate 9. Conversely, when the adjusting ring 3 is lowered relative to the base 1, the sliding member 42 moves away from the pair of locking blocks 2, causing the torsion spring 43 to relax and drive the pair of locking blocks 2 to open via its two support legs 433. Thus, with the limiting frame 11 of the adapter 10 base 1 inserted into the track plate 9, the pair of locking blocks 2 can be locked against the inner walls of the limiting opening 911 of the track plate 9.

[0068] It should be noted that by changing the form of the torsion spring 43, it is also possible to make the locking block 2 lock on both sides of the inner wall of the limiting port 911 of the track plate 9 when the adjusting ring 3 is lifted relative to the base 1, and when the adjusting ring 3 is lowered relative to the base 1, the adapter 10 can be removed from the track plate 9 or the limiting bracket 11 of the adapter 10 can be extended into the track plate 9.

[0069] In a preferred embodiment of the adapter 10 described above, referring to... Figure 4 The lower end of the slider 42 may have a sliding post 422 extending along its sliding direction. Figure 3 The adapter 10 also includes an inner seat 8, which is disposed on the base 1 and its bottom end extends into the limiting bracket 11. The inner seat 8 has mounting grooves 81 for a pair of locking blocks 2 and a sliding groove for sliding the sliding column 422. In this way, by setting the inner seat 8, it is easier to set the pair of locking blocks 2 on the base 1 and limit the sliding of the sliding member 42.

[0070] It should be noted that although this embodiment uses the inner seat 8 to limit the sliding of the sliding block, in the absence of the inner seat 8, a corresponding sliding groove can be directly set on the base 1 to cooperate with the sliding column 422 of the sliding member 42 for limiting.

[0071] In a preferred embodiment of the adapter 10 described above, referring to... Figure 2 An arc-shaped cavity 51 is formed on the outer side of the middle seat 5. A mounting bracket 31 is provided on the inner wall of the adjusting ring 3, and the mounting bracket 31 is located in the arc-shaped cavity 51. The adapter 10 also includes at least one elastic element 312, which is disposed between the mounting bracket 31 and the top surface of the arc-shaped cavity 51, so as to press the adjusting ring 3 against the base 1 in the axial direction, thereby causing a pair of locking blocks 2 to be in an open state. Thus, in the normal state, the elastic element 312 can press the adjusting ring 3 against the base 1, and the adapter 10 can be held in place on the track plate 9 by the locking blocks 2, so as to make the connection between the adapter 10 and the track plate 9 more reliable.

[0072] For example, the mounting bracket 31 may have at least one positioning post 311 and at least one connecting hole, both facing the top surface of the arc-shaped cavity 51. The elastic element 312 may be a spring, which is sleeved on the positioning post 311 and rests between the mounting bracket 31 and the top surface of the arc-shaped cavity 51. The upper end of the spring is bent into a connecting rod parallel to the axis, and the connecting rod is inserted into the connecting hole on the mounting bracket 31. In this way, when the adjusting ring 3 moves axially relative to the base 1, the positioning post 311 can position the spring, making the spring setting more reliable. At the same time, since the connecting rod at one end of the spring is inserted into the connecting hole on the mounting bracket 31, the spring can better maintain its function of not being misaligned and normally extending and contracting along its own axis when the adjusting ring 3 rotates relative to the base 1.

[0073] Specifically, the present invention can achieve the following objectives:

[0074] Firstly, after the adapter 10 is installed on the track plate 9, by changing the axial position of the adjusting ring 3 relative to the base 1, the pair of locking blocks 2 of the adapter 10 are opened and locked onto the inner walls on both sides of the limiting port 911.

[0075] Secondly, after the adapter 10 is installed on the track plate 9, by rotating the adjusting ring 3, the two conductive plugs 62 of the adapter 10 will extend in opposite directions relative to the limiting frame 11 and connect with the conductive plugs 92 on the left and right walls inside the track plate 9 to conduct electricity.

[0076] This invention relates to the field of electrical equipment technology, and in particular to an adapter 10 and a track-mounted socket having the same. The base 1 of the adapter 10 is further provided with a pair of locking blocks 2 and a transmission mechanism 4. After the limiting bracket 11 on the base 1 of the adapter 10 is inserted into the limiting opening 911 of the track plate 9, the adjusting ring 3 moves axially relative to the base 1, and the transmission mechanism 4 causes the two locking blocks 2 to simultaneously extend from both sides of the limiting bracket 11 to engage with the inner walls of both sides of the limiting opening 911 of the track plate 9. Furthermore, by rotating the adjusting ring 3, the two conductive inserts 62 of the adapter 10 can extend in opposite directions relative to the limiting bracket 11 to complete the insertion and conduction with the track plate 9.

[0077] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
