Description

Technical Field

[0001] The present invention relates to an accessory for a lighting device, and particularly to a rotatable lamp head device. Background Art

[0002] Current energy-saving lamps and most lighting lamps on the market are in a fixed mode, making the center line of the lamp fixture always fixed and unable to rotate left and right or up and down. Once installed, when there are lighting dead angles due to unreasonable room layout, due to the fixed mode of the lamp fixture, the wiring layout often needs to be reset, consuming a large amount of labor and money.

[0003] Especially for some lamps with directivity, since their irradiation directions cannot be adjusted, and the positions of the lamp feet sockets are basically fixed, the positions of the lamp tubes are also basically fixed and cannot perform circumferential movement. In some application scenarios, the situation where the lamp cannot directly shine on the irradiation object will occur, resulting in poor lighting effects or inability to be used normally.

[0004] In addition, there are traditional lamp heads that use universal joints to achieve rotation. However, when installing the universal joints, the electrical connection between the lamp head and the lamp socket is seriously affected. Often, additional wiring and locking nuts are required, which is time-consuming and laborious and wastes a lot of manpower and material resources. Summary of the Invention

[0013] Further, a keyway is provided on the rotating shaft, and one end of the plug connector has a screwing portion, and the screwing portion correspondingly extends into the keyway so that the rotating shaft rotates when the conductive terminal rotates.

[0014] Further, a limiting block protrudes in the middle of the plug connector, and the limiting block is used for mating and clamping with the limiting groove of the rotating joint to prevent the conductive terminal from rotating relative to the rotating joint.

[0015] Further, a notch is provided in the middle of the plug connector, and a convex block is provided on the rotating joint; the convex block of the rotating joint is used for being clamped into the notch of the plug connector to prevent the conductive terminal from rotating relative to the rotating joint.

[0025] Please also read Figure 4 The conductive terminal 10 includes a plug connector 11, two conductive sheets 18 inserted into the plug connector 11, and wires 19 electrically connected to the conductive sheets 18. The wires 19 are used to electrically connect to the circuit of the lamp holder. One end of the wire 19 is electrically connected to the conductive sheet 18, and the other end passes through the rotating connector 40, the fixing base 50, the rotating shaft 60 and the elastic element 70. The plug connector 11 is provided with two spaced insertion holes 110 for the conductive sheets 18 to be inserted respectively; a barb 12 extends from one end of the plug connector 11 close to the rotating connector 40, and the barb 12 passes through the rotating connector 40 and is engaged with a side of the rotating connector 40 away from the lamp body connector 20. In this embodiment, there are two barbs 12, and the barbs 12 are respectively located on opposite sides of the plug connector 11. The portion of each barb 12 close to the rotating connector 40 is spaced apart from the plug connector 11, so that the barb 12 has a certain elastic deformation.

[0026] Specifically, the plug connector 11 is hollow along the longitudinal direction, and the jack 110 penetrates through the plug connector 11. A limiting block 13 protrudes from the middle of the plug connector 11, and a limiting groove 41 is provided on the rotary joint 40; the limiting block 13 is used to cooperate with the limiting groove 41 of the rotary joint 40 for clamping to prevent the conductive terminal 10 from rotating relative to the rotary joint 40. In this embodiment, a notch 14 is provided in the middle of the plug connector 11, and a convex block 42 is provided on the rotary joint 40; the convex block 42 of the rotary joint 40 is used to be inserted into the notch 14 of the plug connector 11 to prevent the conductive terminal 10 from rotating relative to the rotary joint 40. An annular boss (not marked in the figure) extends from the middle of the plug connector 11 in the longitudinal direction, and the limiting block 13 and the notch 14 are respectively arranged on the annular boss. When the conductive terminal 10 is assembled with the rotary joint 40, the annular boss abuts and cooperates with the rotary joint 40. In this embodiment, the number of the limiting blocks 13 is two, which are distributed at the opposite ends of the annular boss; the number of the notches 14 is two, which are distributed on the opposite sides of the annular boss; the cross-section of the plug connector 11 is strip-shaped, that is, key-shaped; specifically, one end of the plug connector 11 of the conductive terminal 10 has a screwing portion 115 to cooperate with the connecting rotating shaft 60. The number of the screwing portions 115 is two.

[0027] The lamp body connecting member 20 is arranged in a hollow tubular shape, and the inner wall of the lamp body connecting member 20 is provided with threads for cooperating with and connecting the lamp body. It can be understood that the lamp body connecting member 20 is a nut. An inner convex ring 21 is provided at one end of the lamp body connecting member 20 close to the rotary joint 40 to cooperate with and snap-connect one end of the rotary joint, so that the lamp body connecting member 20 is pivotally connected to the rotary joint 40. In one embodiment, a pivot groove is provided at one end of the lamp body connecting member 20 close to the rotary joint 40, and it is pivotally connected to the rotary joint 40 through the pivot groove.

[0028] Please refer to Figure 3 , the rotary joint 40 is arranged in a hollow circular tubular shape. The pivot assembly further includes a spring retaining ring 49; a clamping groove 43 is provided on the outer wall of the rotary joint 40, and the spring retaining ring 49 is sleeved on the clamping groove 43; when the lamp body connecting member 20 is sleeved on the rotary joint 40 and pressed down forcefully, the spring retaining ring 49 contracts inward and then expands to be snapped into the lamp body connecting member 20 to cooperate with and rotatably install the lamp body connecting member 20 on the rotary joint 40; at this time, the inner convex ring 21 cooperates with the spring retaining ring 49 to prevent the lamp body connecting member 20 from detaching from the rotary joint 40. In this embodiment, the spring retaining ring 49 is arranged in an open circular ring shape; the arc length is about three-quarters of the circumference. One end of the rotary joint 40 close to the fixed seat 50 has an outer convex ring 44, and the outer convex ring 44 is arranged in a circular ring shape for being embedded in the accommodating groove 51 of the fixed seat 50.

[0029] The fixed seat 50 is arranged in a cylindrical shape. The accommodating groove 51 of the fixed seat 50 is arranged in a semi-circular shape, that is, a notch is formed for the outer convex ring 44 of the rotary joint 40 to be snapped into. A retaining ring 510 extends outside the fixed seat 50 corresponding to the accommodating groove 51. The retaining ring 510 is located on the side of the accommodating groove 51 close to the rotary joint 40, so as to axially limit the outer convex ring 44 snapped into the accommodating groove 51 and prevent the outer convex ring 44 from axially disengaging from the accommodating groove 51. A rotating shaft cavity 52 is provided in the middle of the fixed seat 50 to accommodate the rotating shaft 60; the rotating shaft cavity 52 is arranged in a cylindrical shape. A rotating space 53 is provided in the middle of the fixed seat 50. The rotating space 53 is located between the rotating shaft cavity 52 and the accommodating groove 51 and communicates with the rotating shaft cavity 52 and the accommodating groove 51. A retaining point 54 protrudes from the inner wall of the fixed seat 50 corresponding to the rotating space 53. The retaining point 54 is used to achieve partial limit when the rotating shaft 60 rotates relative to the fixed seat 50, so as to prevent the rotating shaft 60 from rotating relative to the fixed seat 50 for more than one week and protect the conductive terminal 10 and the wire 19 from winding. The retaining point 54 is arranged at an interval from the accommodating groove 51. A connecting column 55 is provided on the fixed seat 50. The mounting member 80 is fixed on the connecting column 55 by screwing the screw 90 through the mounting member 80.

[0030] The rotating shaft 60 is generally arranged in a columnar shape and includes a main body portion and an actuating end 61; the main body portion is sleeved with the elastic element 70; the outer diameter of the actuating end 61 is larger than the size of the columnar portion, so that one end of the elastic element 70 sleeved on the main body portion abuts against the side surface of the actuating end 61 facing the main body portion. The actuating end 61 is installed in the rotating shaft cavity 52. In this embodiment, the elastic element 70 is a spring, which is sleeved on the rotating shaft 60 and abuts against the actuating end 61 of the rotating shaft 60 installed in the rotating shaft cavity 52. The rotating shaft 60 has a limiting boss 62, and the limiting boss 62 is located in the rotating space 53; further, the limiting boss 62 extends from the actuating end 61 towards the rotary joint 40, and the limiting boss 62 is correspondingly located at the peripheral position of the rotating space 53, that is, the position close to the inner wall. The limiting boss 62 and the retaining point 54 are in the same circumference, so as to achieve partial limit when the rotating shaft 60 rotates relative to the fixed seat 50. Specifically, both the limiting boss 62 and the retaining point 54 only occupy a small part of the circumference. Therefore, the rotating angle of the rotating shaft 60 relative to the fixed seat 50 is relatively large. For example, the maximum positive and negative rotation angles of the rotating shaft 60 relative to the fixed seat 50 can be 330-350 degrees. When the rotating shaft 60 rotates forward or backward until the boss 62 abuts against the retaining point 54, the limiting effect can be achieved. In other embodiments, if the rotating shaft 60 does not need to rotate relative to the fixed seat 50 with limit, the settings of the limiting boss 62 and the retaining point 54 can be removed.

[0031] On one side of the actuating end 61 of the rotating shaft 60 facing the conductive terminal 10, a keyway 610 is provided; the screwing part 115 correspondingly extends into the keyway 610 so that when the conductive terminal 10 rotates, it drives the rotating shaft 60 to rotate. Specifically, the keyway 610 is cross-shaped, one part is correspondingly clamped into the screwing part 115, and the other part is correspondingly used to accommodate the barb part 12.

[0032] The mounting member 80 has two buckles 81, which can cooperate with various standard lamp socket holders, such as E12, E14, E26, E27, G9, GU10, etc.

[0033] The rotatable lamp head device of the present invention is connected to the lamp body through the conductive terminal 10 and the lamp body connecting member 20, and is connected to the lamp socket holder through the mounting member 80. When connecting to the lamp body, the lamp body connecting member 20 is sleeved on the corresponding threaded part of the lamp body, and the conductive terminal 10 is inserted into the terminal of the lamp body to form an electrical connection; at this time, since the lamp body connecting member 20 is movably connected to other parts of the entire rotatable lamp head device, when rotating the lamp body connecting member 20, there is no need to drive the rotatable lamp head device or the lamp body, and the connection and fixation of the rotatable lamp head device and the lamp body can be easily completed, which is convenient and fast.

[0034] When the lamp body needs to rotate relative to the lamp socket holder, the conductive terminal 10 connecting the lamp body drives the rotating shaft 60 and the rotating joint 40 to rotate. The rotating shaft 60 has frictional damping due to the pressure of the elastic element 70 pushing it onto the fixed seat 50. When the angle of the lamp body is adjusted in place, the angle between the lamp body and the lamp socket holder is fixed by this damping. The setting of the limit boss 62 and the stop point 54 prevents the lamp body from rotating infinitely relative to the lamp socket holder, avoiding damage to the lamp body, especially the wire 19.

[0035] The rotatable lamp head device of the present invention has the functions of being pluggable and rotatable; at the same time, through modular design, it can be connected to various lamp shades and various standard lamp socket holders, and there is no need to re-design and manufacture according to different specifications of lamps, so it has a wide range of applications.

[0036] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0037] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent should be subject to the appended claims.
