Description

Technical Field

[0001] The utility model relates to the technical field of lamps, in particular to a display stand lamp. Background Art

[0002] In places such as exhibitions, display stand lamps are needed to provide lighting. The display stand lamp includes two columns and a lamp slot. The lamp slot is connected between the two columns, and wiring is required in one column. The column and the lamp slot are connected by a pivoting connection mechanism, so that the lamp slot can be rotated to adjust the angle.

[0003] In the prior art, a wire passing channel is provided in the pivoting connection structure. The wire passes out of the column, then enters the lamp slot through the wire passing channel of the pivoting connection structure, and then the wire is connected to the wiring terminal of the lamp board.

[0004] The existing wiring method will result in a relatively long section of wire between the column and the lamp slot. When the lamp slot rotates to adjust the angle, the wire is prone to wrinkling and knotting. When the lamp slot rotates, the wire will move in the wire passing channel of the pivoting connection structure, thus rubbing against the wall surface of the wire passing channel. After long-term use and multiple rotations of the lamp slot, it is easy to cause the wire to become loose from the wiring terminal of the lamp board, affecting normal use. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, and provide a display stand lamp.

On the side of the conductive connector 8 facing the insertion hole 12, there are two conductive contact pieces 83 for cooperating with two conductive terminals 624 to conduct electricity.

[0075] After inserting the insertion post 623 into the insertion hole 12, the first end of the conductive terminal 624 extends into the wiring channel 11 and abuts against the conductive contact piece 83, thereby realizing electrical conduction.

[0076] In the present utility model, the method of using the first connection assembly 6 to connect the first upright post 1 and the light slot 3 is as follows:

[0077] Pre - install the conductive connector 8 in the wiring channel 11 of the first upright post 1, and pre - assemble the first end - cover module 61 and the conductive connection module 62 into the first connection assembly 6.

[0078] Place the first end - cover module 61 near the first end of the light slot 3, and connect the wire 9 extending from the power - receiving end of the lamp board 4 to the second end of the conductive terminal 624. Then, assemble the first end - cover module 61 to the first end of the light slot 3.

[0079] Insert the insertion post 623 into the insertion hole 12. The first end of the conductive terminal 624 extends into the wiring channel 11 and abuts against the conductive contact piece 83, thereby realizing electrical conduction.

[0080] In the present utility model, the second end of the conductive terminal 624 and the lamp board 4 are connected by the wire 9, and the connection between them is a flexible connection, so as to allow the lamp board 4 to rotate a certain angle relative to the conductive terminal 624.

[0081] Compared with the prior art, in the present utility model, only a relatively short wire 9 is connected between the second end of the conductive terminal 624 and the lamp board 4.

[0120] In one embodiment, as Figure 14 、 Figures 17-18 and Figure 21 shown, the second end - cover module 71 includes a second end - cover 711 having a second through - hole 712, and a ring - shaped retaining ring 713 is provided on the hole wall of the second through - hole 712.

[0121] One end of the assembly shaft 72 facing the second column 2 has a protruding assembly end 721, and a retaining head 723 is detachably connected to the other end of the assembly shaft 72.

[0122] The assembly end 721 is assembled in the assembly groove 21, the assembly shaft 72 passes through the retaining ring 713, and the retaining head 723 is located inside the retaining ring 713.

[0123] In this embodiment, the second end - cover module 71 includes a second end - cover 711. The second end - cover 711 is provided with a through - hole second through - hole 712. A ring - shaped retaining ring 713 is integrally provided on the hole wall of the second through - hole 712, and the retaining ring 713 divides the second through - hole 712 into an outer groove 714 and an inner groove 715.

[0124] The second end of the assembly shaft 72 has a protruding assembly end 721. The radial dimension of the assembly end 721 is larger than that of the assembly shaft 72, with high structural strength, so as to be assembled with the assembly groove 21 and improve the connection firmness.

[0125] A retaining head 723, such as a nut, a stop pin, etc., is detachably connected to the first end of the assembly shaft 72, and it can be blocked by the retaining ring 713.

[0126] During assembly, first remove the retaining head 723 from the first end of the assembly shaft 72. After passing the first end of the assembly shaft 72 through the retaining ring 713, then install the retaining head 723 on the first end of the assembly shaft 72, which can prevent the assembly shaft 72 from detaching from the second end - cover module 71. The assembly shaft 72 and the retaining ring 713 are in clearance fit, and the second end - cover module 71 can rotate relative to the assembly shaft 72. Finally, assemble the assembly end 721 into the assembly groove 21 to connect with the second column 2.

[0127] In one embodiment, as Figures 14-17 shown, a sleeve 73 is connected to the inner side of the retaining ring 713, and an elastic member 74 is installed in the sleeve 73. One end of the assembly shaft 72 having a retaining head 723 extends into the sleeve 73 and is press-connected to the elastic member 74.

[0128] In this embodiment, a sleeve 73 is connected to the inner side of the second end cap 711, and one end of the sleeve 73 is threaded into the inner groove 715. The elastic member 74 can be a spring or a spring piece, and it is installed in the sleeve 73. The first end of the assembly shaft 72 extends into the sleeve 73 and is press-connected to the elastic member 74. The retaining head 723 is in clearance fit in the sleeve 73 and can slide relative to the sleeve 73. After assembly, the elastic member 74 presses against the assembly shaft 72, so that the assembly end 721 abuts tightly in the assembly groove 21, avoiding the assembly end 721 from shaking in the assembly groove 21.

[0129] The outer groove 714 also functions to absorb the assembly end 721 during assembly. Specifically, when connecting the assembly shaft 72 to the second column 2, first press the assembly end 721 to overcome the force of the elastic member 74, so that the assembly end 721 is received in the outer groove 714. Then move the second connection assembly 7 from top to bottom. After the assembly end 721 is aligned with the notch of the assembly groove 21, release the assembly end 721. Under the action of the elastic member 74, the assembly end 721 is inserted into the assembly groove 21.

[0130] In one embodiment, as Figures 13-17 shown, the assembly end 721 is a disc, and a limiting groove 722 is provided on the circumferential surface of the disc.

[0133] In this embodiment, the assembly end 721 can also adopt a T-shaped structure. Correspondingly, the assembly groove 21 is also in a T shape. The top notch of the assembly groove 21 is at the top surface of the second column 2. The T-shaped assembly end 721 can be inserted into the T-shaped assembly groove 21 from top to bottom, which is convenient for assembly, and the axial limit is achieved by using the T-shaped structure.

[0134] In one embodiment, as Figures 19-21As shown, an annular boss 724 is integrally connected to the inner side of the assembly end 721. The annular boss 724 is coaxially arranged with the assembly shaft 72. The annular boss 724 is located in the outer groove 714, which plays a role in limiting the inward movement of the assembly shaft 72.
