[0018] The rod connection structure proposed by the utility model is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0019] Figure 1 This is a cross-sectional structural diagram of a rod connection structure of a preferred embodiment of the present application. As shown in the figure, the two rods to be connected are a first rod 3 and a second rod 4, and the connection between the two rods includes at least a hollow tube section 5. The rod connection structure is at least partially arranged inside the hollow tube section 5 as an inner nested member. The rod connection structure includes a first connector 1 and a second connector 2 that cooperate with each other.

[0020] The structure of the first connecting member 1 is as follows Figure 2 As shown, one end thereof is provided with a thread 105. Correspondingly, the first rod 3 is provided with an internal thread, and the first connector 1 and the first rod 3 are threadedly connected. The other end of the first connector 1 includes a first end face 101 facing the second connector 2, and a claw 102 extending from the first end face 101 to the second rod 4. The claw 102 includes an elastic arm 1021 and a buckling portion 1022. The elastic arm 1021 extends from the first end face 101 of the first connector 1 to the connection direction with the second rod 3. At the end of the elastic arm 1021 that is far away from the first end face 101, part of the inner wall of the elastic arm 1021 protrudes toward the center, and the protruding part constitutes the buckling portion 1022. In this embodiment, the hollow pipe section 5 is provided at the connection end of the first rod 3, located outside the area where the internal thread is provided on the first rod 3, that is, the part outside the internal thread close to the second rod 4 is the hollow pipe section 5. After the first connector 1 and the first rod 3 are threadedly connected and fixed, the claw 102 is located in the hollow pipe section 5.

[0021] The structure of the second connecting member 2 is as follows Figure 3 As shown, one end of the second rod 4 is provided with a thread 205, and the end portion of the second rod 4 is provided with an internal thread, and the second connecting member 2 is threadedly connected to the second rod 4. After connection, the other end of the second connecting member 2 protrudes from the connecting end of the second rod 4, and the outer periphery of the protruding portion is recessed inward to form an annular groove as a slot 202 that cooperates with the claw 102. The claw 102 and the slot 202 are snap-connected, and when the clamping portion 1022 enters the slot 202, the elastic arm 1021 needs to be opened outward, so the number of elastic arms 102 is more than 2, and in this embodiment, it is 3. Each elastic arm 1021 is evenly distributed in the circumferential direction, and a spacing space is provided between adjacent elastic arms 1021, so that it can be bent freely. When the clamping portion 1022 is located in the slot 202, the outer side of the elastic arm 1021 contacts the inner wall of the hollow tube section 5, and the inner wall of the hollow tube section 5 limits the elastic arm 1021 from deforming outward, thereby avoiding slipping, making the rod connection safe and reliable.

[0022] During installation, first complete the snap fit of the first connector 1 and the second connector 2, then insert the assembled first connector 1 and the second connector 2 into the hollow pipe section 5, and then connect the rod connection structure provided by the present application to the first rod 3 and the second rod 4 through threads. In this embodiment, the hollow pipe section 5 is connected to the first rod 3, and in other preferred embodiments, the hollow pipe section 5 can also be arranged at the connection end of the second rod 4, or the hollow pipe section can also be divided into two parts, which are respectively arranged at the connection ends of the first rod 3 and the second rod 4, and the present application does not limit this.

[0023] In this embodiment, both ends of the rod connection structure are connected to the rod by threads. While realizing the connection function, the tight fit of the connection between the two rods can be achieved by adjusting the threads. When the outer diameters of the two rods are the same, there is only one seam on the outer peripheral side of the connection, making the lamp simple and beautiful as a whole. Of course, in other preferred embodiments, only one of the first connecting member 1 and the second connecting member 2 can be threaded, and the other can be directly fixed on the rod. Alternatively, a connection method such as snap-fit, interference fit, welding, etc. can be used, which is not limited in this application.

[0024] Since the clamping groove 202 on the second connecting member 2 in the rod connecting structure is an annular groove, the clamping claw 102 can rotate in the circumferential direction after being engaged with it. However, the rod connecting structure is first assembled and then threadedly connected to the first rod 3 and the second rod 4 respectively. When the first connecting member 1 and the second connecting member 2 rotate relative to each other, it will hinder the threaded connection. Therefore, the rod connecting structure of this embodiment also includes a limiting structure, which includes a limiting portion 203 set on the second connecting member surface 2 and a limiting groove 103 set on the first connecting member 1. Figure 3 The limiting portion 203 shown is a protrusion extending from the second end face 201 in the direction of connection with the first rod 3. As shown in the figure, the limiting groove 103 is arranged on the first end face 101 of the first connecting member 1, and is recessed from the first end face 101 to the first connecting member in the direction away from the connection with the second rod 4. In order to avoid interference with the claw 102, the limiting groove 103 is arranged between two adjacent elastic arms 1021. When the claw 102 and the card slot 202 are snap-connected, the limiting portion 203 is located in the limiting groove 103 to prevent the first connecting member 1 from rotating circumferentially relative to the second connecting member. In other preferred embodiments, the limiting portion 203 can also be a geometric shape with a rectangular, waist-shaped, triangular or other cross-section, and the limiting groove 103 is a countersunk hole with matching shape. In this case, the limiting structure can be set in the middle position of the connecting member. However, the rod member in the present application is a supporting structure of the lamp, so wiring is required inside it, such as Figure 1 As shown, the first connector 1 includes a first through hole 104 from the first end surface 101 to the end connected to the first rod 3, and the second connector 2 includes a second through hole 204 from the second end surface 201 to the end connected to the second rod 4. Therefore, it is not convenient to set the limiting structure in the middle position of the connector. In addition to facilitating threaded installation, the limiting structure can prevent the wires inside the rod from rotating when the lighting direction of the lamp needs to be adjusted by rotating one of the first rod 3 or the second rod 4, thereby avoiding winding.

[0025] The rod connection structure of the above embodiment can be used in various lighting devices, such as the lamp poles of table lamps and floor lamps, the lamp bodies of linear lamps, and some rods in chandeliers and decorative lamps. In lighting devices with rods, the rod connection structure provided by the present application can quickly achieve reliable connection between rods, and the rods can rotate freely and are not easy to be tangled.

[0026] The above description of the preferred embodiments of the present invention is for illustration and description, and is not intended to be exhaustive or limited to the specific forms disclosed. Obviously, many modifications and changes may be made, which may be obvious to those skilled in the art and should be included in the scope of the present invention defined by the appended claims.
