[0037] Reference below Figures 1 to 9 A socket for a track-type power supply according to an embodiment of the present invention is described.

[0038] like Figures 1 to 7 As shown, a socket for a track-type power supply according to an embodiment of the present invention includes: a socket body 100 and a base, the socket body 100 includes a bottom plate 110, a shell 120 provided on the bottom plate 110 and a panel 130 movably connected to the shell 120, and also includes at least one press-type self-locking mechanism 400 provided on the bottom plate 110; the base 200 is used to insert the power rail 500, and includes a connecting portion 210 connected to one side of the bottom plate 110 and a slide plate 220, and the slide plate 220 is connected to the side of the connecting portion 210 away from the socket body 100.

[0039] Among them, a conductive sheet 300 is provided in the base 200, one end of the conductive sheet 300 is electrically connected to the conductive contact in the jack of the socket body 100, and the other end is exposed on the side of the slide 220 facing the socket body 100; the press-type self-locking mechanism 400 includes a sleeve 410, a top rod 420, a telescopic component and an elastic member 450 provided on the side of the bottom plate 110 away from the base 200, the top rod 420 is slidably passed through the sleeve 410, and an opening is provided at the end of the sleeve 410 away from the bottom plate 110 to expose the top rod 420, and the telescopic component is provided on the side of the sleeve 410 away from the bottom plate 110. At one end of the opening, an elastic member 450 is provided between the telescopic assembly and the bottom plate 110. The sleeve 410, the top rod 420, and the telescopic assembly 450 are provided with ratchet grooves and ratchet teeth structures. The top rod 420 is continuously pressed by the panel 130, and the ratchet grooves and ratchet teeth on the sleeve 410, the top rod 420, and the telescopic assembly 450 interact with each other, so that the telescopic assembly 450 can rotate continuously, thereby causing the length of the telescopic assembly 450 exposed from the bottom plate 110 to alternately change, thereby changing the pressing state between the conductive sheet 300 exposed from the slide plate 220 and the conductive strip 510 on the inner wall 500 of the power track;

[0040] It can be understood that this socket includes a socket body 100 and a base 200 connected to one side of the socket body 100, the socket body includes a bottom plate 110, a shell 120 provided on the bottom plate 110 and a panel 130 movably connected to the shell 120, the base 200 includes a connecting portion 210 and a slide 220 for inserting the power rail 500, the socket body 100 includes a bottom plate 110 and at least one push-type self-locking mechanism 400 provided on the bottom plate 110, the push-type self-locking mechanism 400 includes a telescopic component provided through the bottom plate 110, when the socket is inserted into the power rail 500, the telescopic component can abut against the outer wall of the power rail 500, and the conductive sheet 300 can abut against the conductive bar 510 on the inner wall of the power rail 500. By pressing the push-type self-locking mechanism 400, the length of the telescopic assembly extending from the base plate 110 can be increased, thereby allowing the slide plate 220 to approach the inner wall of the power rail 500, and then the conductive sheet 300 on the slide plate 220 is pressed against the conductive bar 510 on the inner wall of the power rail 500, thus ensuring close contact between the conductive sheet 300 in the socket and the conductive bar 510 in the power rail 500, thereby avoiding sparking.

[0041] Specifically, the push-type self-locking mechanism 400 includes a sleeve 410, a push rod 420, a telescopic assembly, and an elastic member 450, which are arranged on the side of the bottom plate 110 away from the base 200. The push rod 420 is slidably inserted into the sleeve 410. The end of the sleeve 410 away from the bottom plate 110 is provided with an opening that can expose the push rod 420. The telescopic assembly is arranged at the end of the sleeve 410 away from the opening. The elastic member 450 is arranged between the telescopic assembly and the bottom plate 110. The sleeve 410, the push rod 420, and the telescopic assembly are provided with ratchet grooves and ratchet teeth. When in use, the push rod 420 is continuously pressed through the panel 130, and the ratchet grooves and ratchet teeth on the sleeve 410, the push rod 420, and the telescopic assembly interact with each other, allowing the telescopic assembly to rotate continuously, thereby causing the length of the telescopic assembly exposed from the bottom plate 110 to alternately change, ultimately changing the compression state between the conductive sheet 300 exposed from the slide 220 and the conductive strip 300 on the inner wall of the power track. Therefore, by pressing the panel 130 , tight electrical contact between the socket and the power rail can be achieved, thereby preventing electric sparks.

[0042] Among them, one or more push-type self-locking mechanisms 400 can be provided on the bottom plate 110 .

[0043] It should be understood that when power needs to be cut off, the push-type self-locking mechanism 400 is pressed to shorten the length of the telescopic component extending out of the base plate 110. The socket body 100 is provided with an induction relay. After sensing the retraction of the telescopic component, the induction relay controls the circuit to cut off the power, thereby ensuring that after pressing the top rod 420, the conductive sheet 300 and the conductive strip 510 are separated from the electrical contact, and the socket can be powered off to ensure that no electric sparks will occur when the power is cut off.

[0044] It can be understood that the inner circumference of the sleeve 410 is provided with a plurality of sliding grooves along the axial direction, the sliding grooves pass through the end of the sleeve 410 close to the telescopic component, the sliding grooves include first ratchet grooves 411 and second ratchet grooves 412 arranged alternately, and a first ratchet tooth 413 facing the telescopic component is formed between the adjacent first ratchet grooves 411 and second ratchet grooves 412, and the top rod 420 and / or the sleeve 410 are provided with a guide structure to enable the top rod 420 to slide along the axial direction, and the end of the top rod 420 facing the telescopic component is provided with a plurality of second ratchet teeth 422 along the circumferential direction, and the end of the telescopic component away from the sleeve 410 can pass through the bottom plate 110, and the end of the telescopic component close to the top rod 420 is provided with a plurality of third ratchet teeth 431 along the circumferential direction. The third ratchet tooth 431 can engage with the second ratchet tooth 422, and the telescopic assembly is provided with a plurality of fourth ratchet teeth 432 along the outer peripheral side, and the fourth ratchet tooth 432 and the first ratchet tooth 413 are respectively provided with a first inclined surface 4321 and a second inclined surface 4131 that can cooperate with each other, and the fourth ratchet tooth 432 can be accommodated in the first ratchet groove 411 or the second ratchet groove 412; when the fourth ratchet tooth 432 is accommodated in the first ratchet groove 411, the telescopic assembly can be retracted as a whole into the interior of the socket body 100 under the elastic force of the elastic member 450; when the fourth ratchet tooth 432 is accommodated in the second ratchet groove 412, the telescopic assembly can partially extend out of the side surface of the bottom plate 110 facing the slide plate 220.

[0045] Among them, when the fourth ratchet tooth 432 is accommodated in any ratchet groove, by pressing the push rod 420, the tooth tip of the second ratchet tooth 422 will be able to abut against the upper part of the tooth side of the third ratchet tooth 431, and can drive the fourth ratchet tooth 432 to slide out of the current sliding groove; after the push rod 420 pushes the fourth ratchet tooth 432 to slide out of the sliding groove, the third ratchet tooth 431 will slide along the tooth side of the second ratchet tooth 422 under the elastic force of the elastic member 450, so that the third ratchet tooth 431 engages with the tooth groove of the second ratchet tooth 422 When the fourth ratchet tooth 432 slides out of the slot and the first inclined surface 4321 and the second inclined surface 4131 are partially opposite to each other in the axial direction of the sleeve 410, the telescopic assembly can move toward the slot under the elastic force of the elastic member 450, and the fourth ratchet tooth 432 can enter into another adjacent slot under the cooperation guidance of the first inclined surface 4321 and the second inclined surface 4131.

[0046] When the push rod 420 is continuously pressed, the tooth tip of the second ratchet 422 abuts against the upper part of the tooth side of the third ratchet 431, so that during the process of the push rod 420 pressing the telescopic assembly to extrude the elastic member 450, the telescopic assembly can rotate, so that the third ratchet 431 and the second ratchet 422 are engaged with each other, and the fourth ratchet 432 can slide alternately into the first ratchet groove 411 and the second ratchet groove 412 along the first ratchet 413, so that the telescopic assembly of the bottom plate 110 close to the slide plate 220 is in an alternating state of extension or retraction. When the telescopic assembly extends out of the bottom plate 110, the telescopic assembly can press the outer wall of the power rail 500, and the conductive sheet 300 exposed from the slide plate 220 can press the conductive bar 510 on the inner wall of the power rail 500.

[0047] A plurality of sliding grooves are axially provided on the inner circumference of the sleeve 410, and the sliding grooves pass through one end of the sleeve 410 close to the telescopic assembly. The sliding grooves include a first ratchet groove 411 and a second ratchet groove 412 alternately arranged along the inner circumference of the sleeve 410, and a first ratchet 413 facing the telescopic assembly is formed between adjacent first ratchet grooves 411 and second ratchet grooves 412. The push rod 420 and / or the sleeve 410 are provided with a guide structure to enable the push rod 420 to slide axially. A plurality of second ratchet teeth 422 are circumferentially provided on the push rod 420 toward one end of the telescopic assembly. The telescopic assembly is provided with a plurality of third ratchet teeth 431 circumferentially provided on one end toward the push rod 420, and the third ratchet teeth 431 can engage with the second ratchet teeth 422. A plurality of fourth ratchet teeth 432 are provided on the outer circumference of the telescopic assembly.

[0048] When in use, by pressing the push rod 420, the tooth tip of the second ratchet tooth 422 abuts the tooth side of the third ratchet tooth 431, so that the push rod 420 is pressed against the telescopic assembly to squeeze the elastic member 450. After the fourth ratchet tooth 432 slides out of the ratchet groove, the second ratchet tooth 422 continues to abut the third ratchet tooth 431, and under the elastic restoring force of the elastic member 450, the third ratchet tooth 431 slides along the tooth side of the second ratchet tooth 422 and engages into the tooth groove of the second ratchet tooth 422; then, the first inclined surface 4321 of the fourth ratchet tooth 432 and the second inclined surface 4131 of the first ratchet tooth 413 are opposite to each other in the axial part of the sleeve 410, and the telescopic assembly moves toward the direction close to the sliding groove under the elastic force of the elastic member 450, and under the cooperative guiding action of the first inclined surface 4321 and the second inclined surface 4131, the fourth ratchet tooth 432 enters another adjacent ratchet groove.

[0049] Similarly, the push rod 420 is pressed again so that the tooth tip of the second ratchet tooth 422 abuts against the tooth side of the third ratchet tooth 431, so that the push rod 420 abuts against the elastic member 450 of the telescopic assembly. After the fourth ratchet tooth 432 slides out of the ratchet groove, the second ratchet tooth 422 continues to abut the third ratchet tooth 431, and under the elastic restoring force of the elastic member 450, the third ratchet tooth 431 slides along the tooth side of the second ratchet tooth 422 and engages into the tooth groove of the second ratchet tooth 422; then, the first inclined surface 4321 of the fourth ratchet tooth 432 and the second inclined surface 4131 of the first ratchet tooth 413 are opposite to each other in the axial part of the sleeve 410, and the telescopic assembly moves toward the direction close to the sliding groove under the elastic force of the elastic member 450, and under the cooperative guiding action of the first inclined surface 4321 and the second inclined surface 4131, the fourth ratchet tooth 432 enters another adjacent ratchet groove.

[0050] Because the sliding groove includes the first ratchet groove 411 and the second ratchet groove 412, as the push rod 420 is continuously pressed, the third ratchet tooth 431 can continuously rotate, causing the fourth ratchet tooth 432 to alternately slide into the first ratchet groove 411 and the second ratchet groove 412, thereby causing the length of the telescopic assembly exposed from the bottom plate 110 to alternately change. The distance between the fourth ratchet tooth 432 and the opening varies depending on whether the fourth ratchet tooth 432 slides into the first ratchet groove 411 or the second ratchet groove 412. Therefore, after continuously pressing the push rod 420, the fourth ratchet tooth 432 can slide into the first ratchet groove 411 along the first ratchet tooth 413 under the elastic force of the elastic member 450. When the push rod 420 is pressed again, the fourth ratchet tooth 432 can slide into the second ratchet groove 412 along the first ratchet tooth 413 under the elastic force of the elastic member 450. After the push rod 420 is pressed again, the fourth ratchet tooth 432 can slide into the first ratchet groove 411 again. This cycle repeats, and the length of the telescopic assembly exposed from the bottom plate 110 also alternates. When the fourth ratchet tooth 432 slides into the sliding groove away from the opening, the length of the telescopic component exposed from the bottom plate 110 is longer, and the telescopic component exposed from the bottom plate 110 abuts against the outer wall of the power rail 500, thereby pressing the slide plate 220 against the inner wall of the power rail 500. In addition, the conductive sheet 300 exposed from the slide plate 220 can be pressed against the conductive bar 510 on the inner wall of the power rail 500, thereby ensuring good electrical contact between the conductive sheet 300 in the socket and the conductive bar 510 in the power rail 500 when power is turned on, thereby avoiding electric sparks.

[0051] It can be understood that the telescopic assembly includes a core shaft 440 and a rotating member 430 sleeved on the core shaft 440, the core shaft 440 is provided with a shoulder 441, the rotating member 430 is located on the side of the shoulder 441 close to the top rod 420, the elastic member 450 is sleeved on the core shaft 440 and is located on the side of the shoulder 441 close to the bottom plate 110, so that the rotating member 430 can abut against one side of the shoulder 441, and the elastic member 450 can abut against the other side of the shoulder 441, the third ratchet 431 is provided at one end of the rotating member 430 close to the top rod 420, and the fourth ratchet 432 is provided on the outer peripheral side of the rotating member 430. For example, Figure 7 As shown, in this embodiment, the telescopic assembly includes a core shaft 440 provided with a shoulder 441 and a rotating member 430 sleeved on the core shaft 440, the rotating member 430 is arranged on the side of the shoulder 441 close to the sleeve 410, the elastic member 450 is arranged on the side of the shoulder 441 away from the sleeve 410, the third ratchet 431 is arranged at one end of the rotating member 430 close to the top rod 420, and the fourth ratchet 432 is arranged on the outer peripheral side of the rotating member 430. By separating the rotating member 430 and the core shaft 440, the rotating member 430 is easy to replace when it is worn.

[0052] It should be understood that the rotating member 430 and the core shaft 440 may also be provided in the form of a single component.
