Referring to fig. 3, the rotary joint 40 is disposed in a hollow circular tube shape. The pivoting assembly further includes a spring collar 49; a clamping groove 43 is formed in the outer wall of the rotating joint 40, and a spring clamping ring 49 is sleeved on the clamping groove 43; when the lamp body connecting piece 20 is sleeved on the rotary joint 40 and is pressed down by force, the spring retainer ring 49 contracts inwards and then expands to be clamped in the lamp body connecting piece 20 so as to be matched with the lamp body connecting piece 20 to be rotatably arranged on the rotary joint 40; at this time, the inner collar 21 engages the spring collar 49 to prevent the lamp body attachment member 20 from being disengaged from the rotary joint 40. In the present embodiment, the spring retainer ring 49 is disposed in an open ring shape; the arc length is about three quarters of a circle. The rotating joint 40 has an outer protruding ring 44 at an end thereof adjacent to the fixing seat 50, and the outer protruding ring 44 is disposed in a circular ring shape and is configured to be inserted into the receiving groove 51 of the fixing seat 50.

The fixing base 50 is disposed in a cylindrical shape. The receiving groove 51 of the fixing seat 50 is disposed in a semicircular shape, i.e. a notch is formed for the outer convex ring 44 of the rotating joint 40 to be clamped in. A retaining ring 510 extends from the fixing seat 50 to the outside of the receiving groove 51, and the retaining ring 510 is located at a side of the receiving groove 51 close to the rotating joint 40, so as to axially limit the outward protruding ring 44 clamped in the receiving groove 51 and prevent the outward protruding ring 44 from axially coming out of the receiving groove 51. The middle part of the fixed seat 50 is provided with a rotating shaft cavity 52 for accommodating the rotating shaft 60; the shaft cavity 52 is cylindrically shaped. The middle of the fixing seat 50 is provided with a rotating space 53, and the rotating space 53 is located between the rotating shaft cavity 52 and the accommodating groove 51 and communicates the rotating shaft cavity 52 and the accommodating groove 51. The inner wall of the fixing base 50 is convexly provided with a blocking point 54 corresponding to the rotating space 53, and the blocking point 54 is used for realizing local limiting when the rotating shaft 60 rotates relative to the fixing base 50, so that the rotating shaft 60 is prevented from rotating relative to the fixing base 50 for more than one circle, and the conductive terminal 10 and the lead 19 are protected from winding. The stopping point 54 is spaced from the accommodating groove 51. The fixing seat 50 is provided with a connecting column 55, and the mounting part 80 passes through the mounting part 80 through a screw 90 and then is screwed and fixed on the connecting column 55.

The rotating shaft 60 is substantially arranged in a cylindrical shape and comprises a main body part and an actuating end 61; the main body portion is provided for the elastic element 70 to be sleeved; the outer diameter of the actuating end 61 is larger than the size of the cylindrical 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 actuation end 61 is mounted in the spindle 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 rotation shaft 60 has a limit boss 62, and the limit boss 62 is located in the rotation space 53; further, a limit boss 62 extends from the actuating end 61 toward the rotary joint 40, and the limit boss 62 is correspondingly located at a peripheral position of the rotating space 53, i.e., a position close to the inner wall. The limit boss 62 and the stop point 54 are located in the same circumference, so that the rotating shaft 60 is partially limited when rotating relative to the fixed seat 50. Specifically, the limiting protrusion 62 and the stopping point 54 both occupy only a small portion of the circumference, so that the rotation angle of the rotating shaft 60 relative to the fixing base 50 is relatively large, for example, the maximum angle of the rotating shaft 60 relative to the fixing base 50 in forward and reverse rotation can be 330 degrees and 350 degrees. When the rotating shaft 60 rotates forwards or reversely until the boss 62 is in abutting contact with the stop point 54, a limiting effect can be achieved. In other embodiments, the limiting projection 62 and the catch point 54 can be eliminated if the rotation shaft 60 does not need to be limited in rotation relative to the fixing base 50.

A key groove 610 is arranged on one surface of the actuating end 61 of the rotating shaft 60 facing the conductive terminal 10; the screwing portion 115 correspondingly extends into the key slot 610, so that the conductive terminal 10 rotates to drive the rotating shaft 60 to rotate. Specifically, the key slot 610 is disposed in a cross shape, one part of which is correspondingly inserted into the screwing portion 115, and the other part of which is correspondingly accommodated in the barb portion 12.

The mounting member 80 has two clips 81 that can mate with various standard lamp sockets, such as E12, E14, E26, E27, G9, GU10, etc.

The rotatable lamp holder device of the present invention is connected to the lamp body through the conductive terminal 10 and the lamp body connector 20, and is connected to the lamp holder base through the mounting member 80. When the lamp body is connected, the lamp body connecting piece 20 is sleeved on the corresponding thread part of the lamp body, and the conductive terminal 10 is inserted into the terminal of the lamp body to form conductive connection; at this moment, because the lamp body connecting part 20 is movably connected with other parts of the whole rotatable lamp cap device, the rotatable lamp cap device or the lamp body does not need to be driven when the lamp body connecting part 20 is rotated, the rotatable lamp cap device and the lamp body are easily connected and fixed, and the lamp is convenient and fast.

When the lamp body needs to rotate relative to the lamp base, the conductive terminal 10 connected to the lamp body drives the rotating shaft 60 and the rotating joint 40 to rotate, the rotating shaft 60 is pushed to the fixing seat 50 by the pressure of the elastic element 70 to have friction damping, and after the angle of the lamp body is adjusted to the right position, the angle between the lamp body and the lamp base is fixed by the damping. The limiting bosses 62 and the stopping points 54 are arranged, so that the lamp body cannot rotate infinitely relative to the lamp holder base, and the lamp body, particularly the lead 19, is prevented from being damaged.

The rotatable lamp holder device of the utility model has the functions of plugging in electricity and rotating; meanwhile, the lamp can be connected with various lamp shades and various standard lamp holder bases through modular design, redesigning and manufacturing of lamps with different specifications are not needed, and the application is wide.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
