Detailed Implementation

[0037] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0038] This utility model relates to a lamp connection structure, including a lamp housing 100, a rotating shaft 200, and a connector 300.

[0039] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the lamp housing 100 can be configured as a long rod. The lamp housing 100 has a first connecting end 110. One or both ends of the strip-shaped lamp housing 100 can serve as the first connecting end 110. The interior of the rotating shaft 200 is hollow, forming a wire-passing hole 210, which passes through the rotating shaft 200 along its axial direction. A portion of the shaft of the rotating shaft 200 is installed in the first connecting end 110, and the rotating shaft 200 can be inserted into the first connecting end 110 by plugging it in. The wire-passing hole 210 communicates with the interior of the lamp housing 100. The connector 300 is hollow, and a portion of the shaft of the rotating shaft 200 can be installed into the connector 300 by plugging it in. The connector 300 can be supported by the rotating shaft 200, and the rotating shaft 200 of the connector 300 can rotate relative to the first connecting end 110 around its axial direction. The connector 300 has at least two first conductive terminals 310. The first conductive terminals 310 are pinhole-shaped. The first conductive terminal 310 can be formed by winding copper sheets. The first conductive terminal 310 can be directly plugged into the connector 300, or each first conductive terminal 310 can be mounted on a connector 330, which can be fixed to the connector 300 by screws, snap-fits, or other methods. One end of each first conductive terminal 310 is located on the side of the connector 300 away from the first connecting end 110, and each first conductive terminal 310 extends into the interior of the connector 300. Each first conductive terminal 310 can be connected by a connecting wire, which passes through the wire hole 210 and is introduced into the interior of the lamp housing 100. The lamp housing 100 contains electrical components such as a circuit board 630, and the wire is electrically connected to these components after entering the lamp housing 100. In actual use, an external power supply unit or other mechanism is connected to the connector 300. The power supply unit's output terminal is paired with each first conductive terminal 310 for power supply. With connector 300 and rotating shaft 200 as supports, lamp housing 100 can rotate relative to connector 300 around the central axis of rotating shaft 200, thereby changing the illumination direction of the lamp source inside lamp housing 100. At the same time, connector 300 can be used to connect with external electrical appliances to achieve electrical conduction, making it convenient to use.

[0040] In some specific embodiments of this utility model, such as Figure 1 , Figure 3 , Figure 4 and Figure 8As shown, a slot 220 is provided on the outer wall of the rotating shaft 200. The slot 220 can be located near one end of the rotating shaft 200 and extends around the central axis of the rotating shaft 200. A through hole matching the shape of the rotating shaft 200 is provided on the first connecting end 110, and the through hole communicates with the interior of the lamp housing 100. The rotating shaft 200 is inserted into the first connecting end 110 through the through hole, and the slot 220 passes through the through hole into the interior of the lamp housing 100. Then, a retaining spring 230 is inserted into the interior of the lamp housing 100 and engages with the slot 220. The retaining spring 230 can abut against the end of the first connecting end 110 located inside the lamp housing 100. The retaining spring 230 is used to restrict the rotating shaft 200 from disengaging from the first connecting end 110 in the direction of the connector 300, thereby restricting the rotating shaft 200 from axially disengaging from the lamp housing 100.

[0041] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, a first locking screw 120 is installed on the first connecting end 110. The first locking screw 120 can be screwed into the through hole of the first connecting end 110 from the outside. After the rotating shaft 200 is installed into the through hole of the first connecting end 110, the first locking screw 120 is perpendicular to the axial direction of the rotating shaft 200. As the first locking screw 120 is screwed into the first connecting end 110, the end of the first locking screw 120 can abut against the outer wall of the rotating shaft 200. By using the first locking screw 120 abutting against the rotating shaft 200, the rotating shaft 200 and the first connecting end 110 are relatively fixed, restricting the rotation and axial movement of the rotating shaft 200 relative to the first connecting end 110.

[0042] In some specific embodiments of this utility model, such as Figure 4 and Figure 8As shown, the outer wall of the rotating shaft 200 is provided with a shoulder 240. The shoulder 240 can be provided on the end of the rotating shaft 200. The shoulder 240 is annular and protrudes radially along the rotating shaft 200. The interior of the connector 300 is hollow to form a mounting hole 320. The mounting hole 320 passes through the connector 300 axially. A step 321 is provided inside the mounting hole 320. The rotating shaft 200 is coaxially inserted into the mounting hole 320. The shoulder 240 abuts against the step 321, and a part of the shaft of the rotating shaft 200 extends out of the mounting hole 320. By using the shoulder 240 and the step 321 to mutually limit each other, the rotating shaft 200 is prevented from disengaging from the connector 300 in the direction of the first connecting end 110. With the cooperation of the aforementioned retaining ring 230, the lamp housing 100, the rotating shaft 200 and the connector 300 are axially limited, preventing the lamp housing 100, the rotating shaft 200 and the connector 300 from axially disengaging from each other. The connector 300 can rotate relative to the rotating shaft 200 about its central axis. A sealing ring 400 can be provided between the rotating shaft 200 and the mounting hole 320. One or more sealing rings 400 can be provided, and the sealing ring 400 is sleeved on the rotating shaft 200, with its outer wall abutting against the inner wall of the mounting hole 320. The sealing ring 400 increases the friction between the rotating shaft 200 and the connector 300, thereby positioning the connector 300 relative to the rotating shaft 200 about axially. The sealing ring 400 is closer to the first connecting end 110 than the shaft shoulder 240, thus sealing the connection between the rotating shaft 200 and the connector 300.

[0043] In some specific embodiments of this utility model, such as Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, a positioning plate 500 is provided on the first connecting end 110. A recessed groove can be provided on the end face of the first connecting end 110 facing the connector 300, and the shape of the recessed groove is adapted to the shape of the positioning plate 500. The positioning plate 500 is installed in the recessed groove and then fastened by screws or adhesive. The positioning plate 500 is provided with multiple limiting holes 510, and the limiting holes 510 are arranged sequentially around the rotating shaft 200, that is, the limiting holes 510 are arranged on the same circumference. A ball bearing 520 is installed on the connector 300. The ball bearing 520 can be a combination of a spring and a ball. The ball bearing 520 faces the positioning plate 500. The spring exerts an elastic force on the ball bearing in the direction of the positioning plate 500. When the connector 300 rotates relative to the first connecting end 110, the ball bearing 520 can rotate and slide into and out of each limiting hole 510 in sequence. By engaging the pin 520 with the limiting hole 510, the connector 300 can be fixed in the current turning position relative to the first connecting end 110. When the pin 520 slides into the limiting hole 510, it will also emit a ticking sound.

[0044] In some embodiments of this utility model, such as Figure 7 As shown, each first conductive terminal 310 extends parallel to the axial direction of the rotating shaft 200. One end of each first conductive terminal 310 is located on the side of the connector 300 away from the first connecting end 110. When used in conjunction with an external power supply or other mechanism, the power supply can be inserted along the axial direction of the rotating shaft 200, and the power transmission end of the power supply can be connected to the first conductive terminal 310 in the insertion direction.

[0045] In some specific embodiments of this utility model, such as Figure 9 , Figure 10 and Figure 11 As shown, it also includes an adapter 600. The adapter 600 has at least two second connection ends 610. The adapter 600 may have two, three, or more second connection ends 610. Figure 13 As shown, when the adapter 600 is provided with two second connecting ends 610, the two connecting ends can be arranged in a straight line or an L-shape. For example... Figure 10 and Figure 14 As shown, when the adapter 600 is provided with three third connection terminals, the three third connection terminals can be distributed in a Y-shape or a T-shape. For example... Figure 15 As shown, when the adapter 600 is provided with four third connection terminals, the four third connection terminals can be distributed in a cross shape or an X shape. The second connection terminal 610 can extend from the adapter in a tubular shape. The shape of the second connection terminal 610 is adapted to the shape of the connector 300. Each second connection terminal 610 is provided with a pin-shaped second conductive terminal 620. The second conductive terminal 620 on the second connection terminal 610 is paired and electrically connected to the second wire terminals on other second connection terminals 610. Alternatively, a circuit board 630 can be installed inside the adapter 600, and each second conductive terminal 620 on each second connection terminal 610 can be connected to the circuit board 630 via wires, forming a conductive circuit using the circuit board 630. The connector 300 can be inserted into the second connection terminal 610, and the first conductive terminal 310 and the second conductive terminal 620 are paired and inserted to achieve electrical connection. Different lamps or other electrical appliances can be connected to the adapter 600 via connector 300, and power can be supplied through the second conductive terminals 620 of each second connection end 610 on the adapter 600. For example, Figure 5 and Figure 11As shown, the second connecting end 610 is provided with a guide strip 611, and the connector 300 is provided with a guide groove 340. The guide strip 611 and the guide groove 340 extend axially along the rotating shaft 200. When the connector 300 is inserted into the second connecting end 610, the guide strip 611 slides into the guide groove 340, thereby ensuring the alignment and insertion of the connector 300 and the second connecting end 610, that is, ensuring the mating and insertion of the first conductive terminal 310 and the second conductive terminal 620. The second connecting end 610 is provided with a second locking screw 700 arranged axially perpendicular to the rotating shaft 200. After the connector 300 is inserted into the second connecting end 610, the second locking screw 700 is screwed into the second connecting end 610, and the second locking screw 700 abuts against the connector 300, thereby securing the connector 300 and the second conductive end relative to each other.
