[0028] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0029] See also Figures 1 to 4 As shown, this embodiment discloses an adapter, comprising a rotatably connected rotating seat 1 and a main body 2, the rotating seat 1 is provided with a limiting boss 11 arranged along the radial direction of the rotating seat 1, the rotating seat 1 is provided with a locking position 12, and the main body 2 is provided with a locking mechanism 4 for locking the rotating seat 1.

[0030] The locking mechanism 4 includes a locking tongue member 41, a driving assembly 42 for driving the locking tongue member 41 to move in a direction away from the rotating seat 1, and an elastic member 43 for driving the locking tongue member 41 to move in a direction close to the rotating seat 1. In this embodiment, the elastic member 43 is a column spring.

[0031] The locking tongue member 41 is provided with a locking end 411 and a pushing inclined surface 412 in sequence in a direction away from the rotating seat 1. The locking end 411 has a first position which is located at the locking position 12 and is relatively fixed to the rotating seat 1 in the circumferential direction, and a second position which can rotate relative to the rotating seat 1. The first position and the second position are provided in sequence in a direction away from the rotating seat 1.

[0032] The driving assembly 42 includes a driving member 421 that can reciprocate along the radial direction of the rotating seat 1 . The pushing slope 412 is inclined outwardly in the radial direction of the rotating seat 1 away from the rotating seat 1 , and the pushing slope 412 is in active contact with the driving member 421 .

[0033] During installation, the limiting boss 11 of the rotating seat 1 is inserted into the power-carrying guide rail. Since the limiting boss 11 is limited by the opening of the power-carrying guide rail, when the main body 2 is rotated, the rotating seat 1 is fixed relative to the power-carrying guide rail, and the main body 2 rotates relative to the rotating seat 1 and the power-carrying guide rail. At this time, the locking end 411 is in the second position where it can rotate relative to the rotating seat 1, and the locking tongue member 41 rotates relative to the rotating seat 1 until the main body 2 moves to a predetermined angle position, and the locking end 411 is located at the position where the locking position 12 is located. In this embodiment, when the main body 2 is in the predetermined angle position, the adapter is just in the power-taking state, and the locking tongue member 41 moves toward the direction close to the rotating seat 1 under the action of the elastic member 43, thereby switching the locking end 411 from the second position to the first position where the locking position 12 is located and is relatively fixed to the rotating seat 1 in the circumferential direction. The rotating seat 1 and the main body 2 are relatively fixed in the circumferential direction, and the main body 2 can no longer rotate, thereby making the adapter in a locked state, and the adapter cannot be removed from the power-carrying guide rail.

[0034] When it is necessary to remove the adapter from the powered rail, the driving member 421 is moved inwardly along the radial direction of the rotation of the rotating seat 1 until the driving member 421 abuts against the pushing inclined surface 412. As the driving member 421 approaches, since the pushing inclined surface 412 is inclined outwardly in the radial direction of the rotation of the rotating seat 1 away from the rotating seat 1, the pushing inclined surface 412 is pushed by the driving member 421, overcomes the elastic force of the elastic member 43, and moves in the direction away from the rotating seat 1, and the locking end 411 moves in the direction away from the rotating seat 1 accordingly, so that the locking end 411 is located at the locking position 12 and is fixed relative to the rotating seat 1 in the circumferential direction. The first position is switched to the second position which can rotate relative to the rotating seat 1, so that the adapter is in an unlocked state, and the locking tongue member 41 can be rotated to the initial position, so that the adapter can be smoothly removed from the energized guide rail. After taking out the adapter, the driving member 421 moves outward along the radial direction of the rotation of the rotating seat 1, and the driving member 421 moves away from the pushing inclined surface 412. The locking tongue member 41 loses the force of the driving member 421, and under the action of the elastic member 43, it moves again in the direction close to the rotating seat 1. However, since the locking end 411 is not at the locking position 12 at this time, it will not switch to the first position and remains in the second position.

[0035] In the present invention, a locking mechanism 4 consisting of a locking tongue member 41, a driving assembly 42 and an elastic member 43 is provided between the main body 2 and the rotating seat 1. When the adapter needs to be fixed, the locking tongue member 41 is rotated to the position where the locking position 12 of the rotating seat 1 is located, and under the action of the elastic member 43, the locking end 411 is switched from the second position where it can rotate relative to the rotating seat 1 to the first position where it is located at the locking position 12 and is relatively fixed to the rotating seat 1 in the circumferential direction. Under the action of the locking tongue member 41, the rotating seat 1 and the main body 2 are relatively fixed in the circumferential direction, and the main body 2 can no longer rotate, thereby making the main body 2 and the rotating seat 1 fixed to each other. The adapter is in a locked state during the entire period of time, and the adapter cannot be removed from the powered rail, so as to avoid the adapter from falling and being damaged due to unexpected external force. When the adapter needs to be removed, the driving member 421 pushes against the pushing slope 412 on the locking tongue member 41, so that the locking tongue member 41 moves in a direction away from the rotating seat 1, thereby switching the locking end 411 from the first position to the second position, and the locking tongue member 41 can be rotated to the initial position, and then the adapter can be taken out. The switching operation between locking and unlocking of the adapter is simple, the coordination between the components is more stable, the function resetting is more stable, it is not easy to have function failure problems, and the service life is longer.

[0036] Among them, see Figure 4 and Figure 5As shown, the driving member 421 includes an operating end 423 and a pushing rod 424 that are connected to each other. The pushing rod 424 is arranged along the radial direction of rotation of the rotating seat 1. The pushing rod 424 is movably in contact with the pushing inclined surface 412. An elastic reset member 422 is pressed against between the operating end 423 and the locking tongue member 41. In this embodiment, the elastic reset member 422 is a column spring.

[0037] In this embodiment, the operating end 423 is a button. By pressing the operating end 423, the pushing rod 424 is driven to move inward in the radial direction of the rotation of the rotating seat 1, gradually approaching the pushing inclined surface 412, and the elastic reset member 422 is compressed and accumulates force until the pushing rod 424 is against the pushing inclined surface 412. Under the action of the pushing rod 424, the locking tongue member 41 moves in the direction away from the rotating seat 1, thereby switching the locking end 411 from the first position to the second position.

[0038] The end of the pushing rod 424 is in a curved structure to reduce the resistance of pushing against the pushing inclined surface 412 .

[0039] The elastic reset member 422 is used to realize automatic reset of the operating end 423. After the external force of the operating end 423 is removed, under the action of the elastic reset member 422, the driving member 421 moves outward along the radial direction of the rotation of the rotating seat 1 to realize automatic reset.

[0040] Among them, see Figures 3 to 5 As shown, the lock tongue member 41 is provided with a mounting groove 413 for accommodating the elastic reset member 422, and the pushing slope 412 is provided on both sides of the mounting groove 413. By arranging a pushing slope 412 on each side of the lock tongue member 41, the driving member 421 is correspondingly provided with two pushing rods 424, so that the force on the lock tongue member 41 is more uniform, and the stability of the cooperation between the components is improved. By setting the mounting groove 413, the stability of the installation of the elastic reset member 422 is ensured, and the stability of the cooperation between the components is further improved.

[0041] Among them, see Figure 3 , Figure 5 and Figure 6 As shown, the rotating seat 1 is provided with a rotating base plate 13, the main body 2 is provided with a rear wall 31, the rotating base plate 13 and the rear wall 31 are arranged parallel to each other, the locking end 411 extends out of the rear wall 31 and conflicts with the rotating base plate 13, the locking position 12 is provided on the rotating base plate 13, and the rotating base plate 13 is provided with a limiting portion for positioning the locking end 411 on the locking position 12.

[0042] In one embodiment, the limiting portion is a limiting groove (not shown), and the locking end 411 is limited by the limiting groove. The locking end 411 extends from the outside of the limiting groove into the limiting groove, thereby switching from the second position to the first position.

[0043] In another embodiment, see Figures 2 to 6 As shown, the limiting portion includes a limiting slider 14 and a protrusion 15 formed in a direction protruding toward the rear wall 31. The rear wall 31 is provided with an arc-shaped slide rail 32 for the limiting slider 14 to slide. The center of the arc-shaped slide rail 32 falls on the axis of rotation of the rotating seat 1, and the angle of the arc-shaped slide rail 32 is consistent with the angle corresponding to the one-way rotation trajectory of the locking tongue member 41. The two ends of the arc-shaped slide rail 32 respectively form a first travel limiting end 321 and a second travel limiting end 322. The first travel limiting end 321 is used to limit the limiting slider 14 in the first rotation The second travel limit end 322 is used to limit the sliding travel of the limit slider 14 in the opposite direction of the first rotation direction. The limit slider 14 has a third position corresponding to the locking end 411 in the first position. The third position is located on the first travel limit end 321, and the protrusion 15 and the locking position 12 are arranged in sequence along the first rotation direction, wherein the first rotation direction can be clockwise or counterclockwise relative to the front side of the adapter. In this embodiment, the first rotation direction is counterclockwise relative to the front side of the adapter.

[0044] During installation, the limiting boss 11 of the rotating seat 1 is inserted into the energized guide rail. At this time, the locking tongue piece 41 is in the initial position until the locking tongue piece 41 rotates to the locking position 12. Since the center of the arc-shaped slide rail 32 falls on the axis of rotation of the rotating seat 1, and the angle of the arc-shaped slide rail 32 is consistent with the angle corresponding to the one-way rotation stroke trajectory of the locking tongue piece 41, the limiting slider 14 is just located at the second stroke limiting end 322 of the arc-shaped slide rail 32 at this time, thereby effectively limiting the rotation direction of the main body 2. The main body 2 can only rotate unidirectionally in the opposite direction of the first rotation direction, and then the main body 2 is rotated until the limiting slider 14 just slides to the first stroke limiting end 321 of the arc-shaped slide rail 32, and the main body 2 can no longer rotate in the second direction. Continue to rotate in the opposite direction of a rotation direction. At this time, the locking tongue member 41 just rotates to the position of the locking position 12. At the same time, the protrusion 15 and the locking position 12 are arranged in sequence along the first rotation direction. Since the locking end 411 moves toward the direction close to the rotating seat 1 under the action of the elastic member 43, the protrusion 15 can prevent the locking end 411 from moving in the first rotation direction, thereby positioning the locking end 411 on the locking position 12. The locking end 411 switches from the second position to the first position where the locking position 12 is located and is relatively fixed to the rotating seat 1 in the circumferential direction. The rotating seat 1 and the main body 2 are relatively fixed in the circumferential direction, and the main body 2 can no longer rotate, thereby making the adapter in a locked state and the adapter cannot be removed from the powered rail.

[0045] When it is necessary to remove the adapter from the powered rail, the driving assembly 42 is used to move the locking tongue piece 41 in the direction away from the rotating seat 1, and the locking end 411 is moved in the direction away from the rotating seat 1 accordingly, so that the locking end 411 is switched from the first position where the locking position 12 is located and relatively fixed to the rotating seat 1 in the circumferential direction to the second position where it can rotate relative to the rotating seat 1, and the protrusion 15 can no longer limit the locking end 411, and because the limit slider 14 is in the third position, the main body 2 can only rotate unidirectionally along the first rotation direction until the limit slider 14 just slides to the second travel limit end 322 of the arc slide rail 32, and the main body 2 is restricted and can no longer continue to rotate along the first rotation direction, and the locking tongue piece 41 just rotates to the initial position, thereby making the adapter in an unlocked state, and the locking tongue piece 41 can be rotated to the initial position, and the adapter is smoothly removed from the powered rail.

[0046] Through the mutual cooperation between the limit slider 14, the protrusion 15 and the arc-shaped slide rail 32, the main body 2 of the adapter can only rotate along the correct locking rotation direction during the locking process, and the locking end 411 can be smoothly positioned on the locking position 12. The main body 2 of the adapter can only rotate along the correct unlocking rotation direction during the unlocking process, and the locking part can be smoothly positioned at the initial position. The locking / unlocking operation is simpler and faster. At the same time, the limit slider 14 and the arc-shaped slide rail 32 can ensure that the rotation of the main body 2 is smoother, thereby improving stability.

[0047] Among them, see Figures 3 to 6 As shown, the projection 15 is an arc-shaped structure, and the center of the arc-shaped structure falls on the axis of rotation of the rotating seat 1. The end of the projection 15 facing the locking tongue member 41 is provided with a toothed end surface 151, and the toothed end surface 151 movably contacts with the locking end 411.

[0048] Through the design of the toothed end surface 151, during the rotation of the locking tongue member 41, the locking tongue member 41 contacts the toothed end surface 151 under the action of the elastic member 43, which can collide to produce a rotation sound and enhance the rotation feel, thereby improving the usability of the product.

[0049] Among them, see Figure 5 As shown, the main body 2 includes a shell frame 3 and a power-collecting component 5. The shell frame 3, the power-collecting component 5 and the locking tongue component 41 are relatively fixed in the circumferential direction. The rear wall 31 is arranged on the shell frame 3. The shell frame 3, the power-collecting component 5 and the locking tongue component 41 form a rotation action community, and the rotation of the power-collecting component 5 can be achieved by rotating the shell frame 3.

[0050] Among them, see Figure 5 and Figure 7As shown, the power-collecting component 5 includes a support frame 51 and a power-collecting base 52 arranged on the support frame 51. The support frame 51 is relatively fixed to the shell frame 3 in the circumferential direction, and the support frame 51 is provided with a receiving groove 511. The lock tongue component 41 is movably arranged in the receiving groove 511. The support frame 51 can protect the power-collecting base 52 and prevent the power-collecting base 52 from shifting, and at the same time, the power-collecting component 5 is relatively fixed to the shell frame 3 in the circumferential direction. In this embodiment, by providing protrusions on the rear wall 31 and the surface cover 32 of the shell frame 3, the power-collecting component 5 is relatively fixed to the support frame 51 in the circumferential direction. The receiving groove 511 on the support frame 51 provides a stable movable platform for the lock tongue component 41, further ensuring the stability of the locking / unlocking function.

[0051] Among them, see Figures 2 to 4 As shown, a mounting boss 414 is provided at one end of the locking tongue member 41 away from the locking end, and the housing 3 includes a face cover 32. The inner wall of the face cover 32 is provided with a mounting cylinder arranged along the same axial direction as the mounting boss 414. The elastic member 43 is pressed against between the mounting boss 414 and the mounting cylinder. One end of the elastic member 43 is sleeved on the mounting boss 414, and the other end extends into the mounting cylinder and is fixed by the mounting cylinder, thereby ensuring that the elastic member 43 is firmly installed and the elastic direction is always along the same axial direction, further ensuring the stability of the locking / unlocking function.

[0052] This embodiment also discloses a track socket, including a powered rail and the above-mentioned adapter.

[0053] Of course, the above illustrations are only preferred implementation modes of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes made to the principles of the present invention should be included in the protection scope of the present invention.
