[0017] Combine the following Figure 1-10 , further describe this application scheme:

[0018] like Figure 1-5 As shown, a button bayonet type magnetic lamp conductive device comprises a shell 1 and a rotating member 3 for being fixedly connected to the lamp body, wherein the rotating member 3 is rotatably mounted on the shell 1 around a predetermined axis L; an angle positioning mechanism is provided between the shell 1 and the rotating member 3; the angle positioning mechanism comprises a spring positioning bead 4 and a plurality of tooth grooves 15 for the spring positioning bead 4 to fall into; the spring positioning bead 4 is provided on the rotating member 3; the tooth grooves 15 are provided on the shell 1 and are evenly spaced around the predetermined axis L.

[0019] An angle positioning mechanism is provided between the shell 1 and the rotating part 3 of the technical solution; when the lamp body is rotated to adjust the angle, the rotating part 3 is driven to rotate, and the spring positioning beads 4 fall into the tooth grooves 15 at different positions for step-by-step positioning to fix the angle after rotation; the spring positioning beads 4 are elastically retractable, and the rotation operation is easy, and a spring sound is emitted during the rotation process, which is convenient for identifying the rotation level and improving the user experience.

[0020] A rotation limiting mechanism is also provided between the shell 1 and the rotating member; the rotation limiting mechanism includes a limiting protrusion 32 provided on the rotating member 3 and extending radially along the predetermined axis L; the shell 1 is provided with a forward rotation stop surface 171 and a reverse rotation stop surface 172 distributed at circumferential intervals around the predetermined axis L; the limiting protrusion 32 rotates between the forward rotation stop surface 171 and the reverse rotation stop surface 172.

[0021] The technical solution sets a rotation limit mechanism to limit the rotation range of the rotating member, thereby preventing the lamp body wire from rotating and winding. When the limit convex portion 32 of the rotating member abuts against the forward rotation stop surface 171, the rotating member is at the maximum forward rotation angle position; when the limit convex portion 32 of the rotating member abuts against the reverse rotation stop surface 172, the rotating member is at the maximum reverse rotation angle position.

[0022] In this embodiment, a stopping protrusion 17 is disposed on the housing, and the forward-rotation stopping surface 171 and the reverse-rotation stopping surface 172 are two symmetrical side surfaces of the stopping protrusion 17 .

[0023] The housing 1 is provided with a lamp pole insertion hole 16 for the lamp pole 5 of the lamp body to be inserted and rotatably connected; the center of the lamp pole insertion hole 16 is on the predetermined axis L; the tooth grooves 15 are distributed around the lamp pole insertion hole 16; the rotating member 3 is provided with a connecting hole 31 fixedly connected to the lamp pole 5.

[0024] During implementation, the lamp pole of the lamp body is sequentially inserted into the connection hole 31 and the lamp pole insertion hole 16; the lamp pole is relatively fixedly connected to the connection hole 31; the lamp pole is rotatably matched with the lamp pole insertion hole 16. When the illumination angle of the lamp body needs to be adjusted, the lamp pole is rotated to drive the rotating member 3 to rotate relative to the housing 1.

[0025] The rotating member 3 is provided with a receiving groove 33 for receiving the spring positioning bead 4 , and the spring positioning bead 4 is installed in the receiving groove 33 .

[0026] The spring positioning bead 4 can adopt the existing integrated spring positioning bead 4, including a marble shell and a spring and a ball installed in the marble shell.

[0027] In this embodiment, the spring positioning bead 4 includes a spring 42 and a positioning bead 41 . One end of the spring 42 is connected to the positioning bead 41 , and the other end of the spring 42 abuts against the receiving groove 33 .

[0028] like Figure 6-10 As shown, button modules 2 are respectively installed at both ends of the housing 1; the button module 2 can move radially along the length direction of the housing 1 to switch between a pressed state and a pop-up state. The button module 2 includes a pressing portion 21 and a buckle portion 22 formed on the pressing portion 21; the buckle portion 22 is provided with a buckle protrusion 221 for buckling with the track. The end surface of the housing 1 is provided with a mounting opening 11, and the side wall of the housing 1 is provided with a through hole 12; the pressing portion 21 is penetrated in the mounting opening 11, the buckle portion 22 is located in the housing 1, and the buckle protrusion 221 is inserted into the through hole 12. When the button module 2 is in the pop-up state, the buckle protrusion 221 penetrates through the through hole 12 and is exposed outside the housing 1; when the button module 2 is in the pressed state, the buckle protrusion 221 is retracted into the through hole 12.

[0029] When the conductive module is installed, the pressing part 21 of the button module 2 is pressed to push it into the shell 1 to switch it to the pressed state, and the snap protrusion 221 is retracted into the through hole 12. At this time, the conductive module can be embedded in the snap-in of the track; then the pressing part 21 is released, and the button module 2 moves toward the outside of the shell 1 and switches to the pop-up state. The snap protrusion 221 passes through the through hole 12 to be exposed outside the shell 1 and is clamped and fixed in the snap-in slot in the track.

[0030] This technical solution realizes the installation of the conductive module by driving the snap protrusion 221 of its own snap part 22 to cooperate with the track through the activity of the button module 2. The structure is simple, easy to install and implement, and low in cost. In addition, the snap part 22 is formed on the button module 2. When it is damaged, only the button module 2 needs to be replaced, thereby reducing maintenance costs.

[0031] The buckle portion 22 includes an elastic arm 222, one end of the elastic arm 222 is relatively fixed to the pressing portion 21, and the other end is a free end; the buckle protrusion 221 is arranged on the free end of the elastic arm 222; when the button module 2 is in the pop-up state, the elastic arm 222 is expanded outward to allow the buckle protrusion 221 to pass through the through hole 12; when the button module 2 is in the pressed state, the elastic arm 222 is retracted inward to allow the buckle protrusion 221 to retract into the through hole 12.

[0032] The buckle protrusion 221 of the present technical solution can be elastically inserted into the through hole 12 under the elastic force of the elastic arm 222 .

[0033] The elastic arm 222 has an elastic arm inclined surface 223 that is inclined from inside to outside; the housing 1 is provided with a housing inclined surface 13 that matches the elastic arm inclined surface 223; when the button module 2 moves radially, the elastic arm inclined surface 223 abuts against the housing inclined surface 13 and moves along the housing inclined surface 13, so that the elastic arm 222 can be retracted inwardly or expanded outwardly. Specifically, the housing 1 is provided with a guide protrusion 14, and the housing inclined surface 13 is provided on the guide protrusion 14.

[0034] The buckle portion 22 of the present technical solution realizes the inward retraction or outward expansion of the elastic arm 222 through the inclined surface cooperation guide. When the button module 2 is pushed into the shell 1, the elastic arm 222 is retracted inwardly under the guidance of the shell inclined surface; when the force pressing the button module 2 is withdrawn, the elastic arm 222 expands outward under the action of its own elastic force, and at the same time retreats along the inclined surface guide to make the button module 2 pop out toward the outside of the shell 1, that is, the button module 2 can be reset without spring drive, which simplifies the installation structure and saves costs.

[0035] The buckle parts 22 include two buckle parts 22; the two buckle parts 22 are symmetrically arranged; the side walls of the housing 1 are respectively provided with through holes 12 for the buckle protrusions 221 of the two buckle parts 22 to be inserted; the buckle protrusions 221 move in the through holes 12 when the button module 2 moves radially. The elastic arm inclined surfaces 223 of the two elastic arms 222 are in an eight-shaped shape. The technical solution is provided with two symmetrical buckle parts 22, and the clamping with the track is stable and high.

[0036] The button module 2 further includes a connecting portion 23 connecting the pressing portion 21 and the buckling portion 22 ; one end of the elastic arm 222 is fixedly connected to the connecting portion 23 .

[0037] The outer end surface of the pressing portion 21 is provided with an anti-skid protrusion 211 to increase the pressing feel and play an anti-skid role.

[0038] The button module 2 is an integrally formed plastic part. The button module 2 itself does not need to be assembled, which simplifies the installation steps and is easy to form and process.

[0039] The above-mentioned preferred implementation modes should be regarded as illustrative examples of the implementation modes of the present application scheme. Any technical deductions, replacements, improvements, etc. that are identical or similar to the present application scheme or made based on this scheme should be regarded as within the scope of protection of this patent.
