Description

A type of display stand light

[0001] This application claims priority to Chinese patent application No. 202411221371.2, filed on September 2, 2024, the entire disclosure of which is incorporated herein by reference. Technical Field

[0002] This invention relates to the field of lighting technology, and more particularly to a display stand lamp. Background Technology

[0003] In venues such as exhibitions, display stand lights are required to provide illumination. A display stand light consists of two uprights and a light trough connected between the two uprights. Wiring is required in one of the uprights. The uprights and the light trough are connected by a pivoting mechanism, allowing the light trough to be rotated and adjusted in angle.

[0004] In the prior art, a wire passage is opened in the pivot connection structure. The wires pass out from the column, then enter the lamp trough through the wire passage of the pivot connection structure, and then connect the wires to the terminal of the lamp board.

[0005] The existing wiring method results in a long section of wire between the column and the light trough. When the light trough is rotated to adjust the angle, the wire will be wrinkled and knotted. When the light trough is rotated, the wire will move in the wire passage of the pivot connection structure, which will cause friction with the wall of the wire passage. After long-term use and repeated rotation of the light trough, the connection between the wire and the light board is prone to loosening, affecting normal use. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display stand lamp that uses a combination of conductive plugs and conductive connection modules to achieve electrical connection between the conductor of the first column and the lamp panel.

[0059] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0060] As shown in Figures 1-15 and 19-21, an embodiment of the present invention provides a display stand lamp, including a first column 1 having a wiring channel 11 and a plug hole 12, a second column 2 having an assembly groove 21, a lamp trough 3 having a lamp panel 4, a first connecting assembly 6 having a first end cap module 61 and a conductive connection module 62, a second connecting assembly 7 having a second end cap module 71 and an assembly shaft 72, and a conductive plug 8 installed in the wiring channel 11 and having a conductive contact 83.

[0061] The first end cap module 61 is detachably connected to one end of the lamp groove 3. The second end cap module 71 is detachably connected to the other end of the lamp groove 3. One end of the mounting shaft 72 is installed in the mounting groove 21, and the second end cap module 71 is pivotally mounted on the mounting shaft 72.

[0062] The conductive connection module 62 includes a connection module body 621, a mounting shaft 622 located on one side of the connection module body 621, a plug post 623 located on the other side of the connection module body 621, and conductive terminals 624 passing through the plug post 623 and the mounting shaft 622.

[0063] The plug pin 623 is inserted into the plug hole 12, and the mounting shaft 622 passes through the first end cover module 61. The first end cover module 61 is detachably connected to the connecting module body 621 and can rotate relative to the mounting shaft 622.

[0064] One end of the conductive terminal 624 is pressed against the conductive contact 83, and the other end of the conductive terminal 624 extends into the lamp groove 3 and is connected to the lamp board 4 through the wire 9.

[0065] The display stand light provided by the present invention includes a first column 1, a second column 2, a light trough 3, a first connecting component 6, a second connecting component 7, and a conductive connector 8.

[0066] The first column 1 has a vertically extending wiring channel 11, and a plug hole 12 is provided on the inner side of the upper end of the first column 1, which communicates with the wiring channel 11. The plug hole 12 is preferably a non-circular hole, also known as an irregular hole, which serves to assemble and prevent rotation.

[0067] The upper end of the second column 2 is provided with an inwardly opening mounting groove 21. In this invention, the inner side refers to the side facing the middle of the lamp groove 3.

[0068] The light trough 3 is roughly U-shaped, and a light panel 4 is installed inside it. A light guide plate 5 is installed at the bottom opening of the light trough 3.

[0069] The first connecting component 6 is used to connect the first column 1 and the first end of the light trough 3. The first connecting component 6 has a first end cap module 61 and a conductive connection module 62. The first end cap module 61 is used to assemble with the first end of the light trough 3 and serves as an end plate or end cap for the first end of the light trough 3, thereby sealing the opening at the first end of the light trough 3. The first end cap module 61 is detachably connected to the light trough 3, specifically through snaps, pins, etc.

[0070] The conductive connection module 62 includes a connection module body 621, a mounting shaft 622, a plug-in post 623, and two conductive terminals 624. The connection module body 621 is block-shaped and is an insulator. The mounting shaft 622 is located inside the connection module body 621 and extends towards the lamp slot 3. The plug-in post 623 is connected to the outside of the connection module body 621 and extends towards the first column 1. The plug-in post 623 and the mounting shaft 622 are arranged approximately coaxially. The outline shape of the plug-in post 623 is adapted to the plug-in hole 12. Preferably, the plug-in post 623 is a non-circular post, also known as an irregular post, which serves to assemble and prevent rotation. The mounting shaft 622, the plug-in post 623, and the connection module body 621 can be integrally formed and are all insulators. The mounting shaft 622 and the plug-in post 623 have through holes for the conductive terminals 624 to pass through. The first end of the conductive terminal 624 extends beyond the plug post 623, and the second end of the conductive terminal 624 extends beyond the mounting shaft 622.

[0071] The first end cap module 61 has a first through hole 612. During assembly, the plug pin 623 is inserted into the plug hole 12, and the mounting shaft 622 passes through the first through hole 612 of the first end cap module 61. The second end of the conductive terminal 624 extends into the lamp slot 3, and the second end of the conductive terminal 624 is connected to the wire 9 of the power receiving terminal of the lamp board 4. The first end cap module 61 and the connecting module body 621 are detachably connected by snaps, pins, etc. The first end cap module 61 is pivotally mounted on the mounting shaft 622, and the first end cap module 61 can rotate relative to the mounting shaft 622.

[0072] The second connecting assembly 7 is used to connect the second column 2 and the second end of the light trough 3. The second connecting assembly 7 includes a second end cap module 71 and an assembly shaft 72. The second end cap module 71 is used to assemble with the second end of the light trough 3 and serves as an end plate or end cap for the second end of the light trough 3, thereby sealing the opening at the second end of the light trough 3. The second end cap module 71 is detachably connected to the light trough 3, specifically through snaps, pins, etc.

[0073] The assembly shaft 72 is coaxially arranged with the mounting shaft 622. The second end of the assembly shaft 72 is fixedly connected to the assembly groove 21 of the second column 2. The second end cover module 71 is pivotally connected to the first end of the assembly shaft 72 and can rotate relative to the assembly shaft 72.

[0074] Therefore, the lamp slot 3 can be rotated and adjusted relative to the mounting shaft 622 and the assembly shaft 72.

[0075] The conductive connector 8 is detachably installed in the wiring channel 11. The side of the conductive connector 8 facing the insertion hole 12 has two conductive contacts 83 for engaging with two conductive terminals 624 to conduct electricity. The conductive contacts 83 are electrically connected to the wires in the wiring channel 11.

[0076] After the plug pin 623 is inserted into the plug hole 12, the first end of the conductive terminal 624 extends into the wiring channel 11 and presses against the conductive contact 83, thereby achieving conductivity.

[0077] In this invention, the first column 1 and the light trough 3 are connected by the first connecting component 6 as follows:

[0078] The conductive connector 8 is pre-installed in the wiring channel 11 of the first column 1, and the first end cap module 61 and the conductive connection module 62 are pre-assembled into the first connection assembly 6.

[0079] The first end cap module 61 is placed near the first end of the lamp trough 3, and the wire 9 extending from the power terminal of the lamp board 4 is connected to the second end of the conductive terminal 624. Then, the first end cap module 61 is assembled to the first end of the lamp trough 3.

[0080] Insert the plug 623 into the plug hole 12, and the first end of the conductive terminal 624 extends into the wiring channel 11 and presses against the conductive contact 83, thereby achieving conductivity.

[0081] In this invention, the second end of the conductive terminal 624 is connected to the lamp board 4 via a wire 9, and the two are connected flexibly, thereby allowing the lamp board 4 to rotate relative to the conductive terminal 624 at a certain angle. When the lamp slot 3 is rotated for adjustment, the conductive terminal 624 remains stationary, while the lamp board 4 rotates relative to the conductive terminal 624.

[0082] Compared with the prior art, in this invention, only a relatively short wire 9 is connected between the second end of the conductive terminal 624 and the lamp board 4. This wire 9 is located in the lamp groove 3, with ample space 30 for movement, and its relatively short length avoids folding, knotting, and friction with the surrounding walls. In this invention, instead of a wire connection between the first column 1 and the first end cover module 61, a conductive terminal 624 and a conductive contact 83 are used for electrical connection. This effectively shortens the length of the wire between the first column 1 and the lamp board 4 and enables modular assembly, improving installation efficiency.

[0083] In one embodiment, as shown in Figures 5 and 8-9, the first end cap module 61 includes a first end cap 611 having a first through hole 612 and a plurality of first buckles 613. The plurality of first buckles 613 are connected to the side of the first end cap 611 facing the connecting module body 621, and the plurality of first buckles 613 are arranged at intervals around the first through hole 612.

[0084] The connecting module body 621 has an annular groove 625 arranged coaxially with the mounting shaft 622 on the side facing the first end cover 611.

[0085] The mounting shaft 622 passes through the first through hole 612. The first latch 613 is fitted in the annular groove 625 and can slide relative to the annular groove 625.

[0086] In this embodiment, the first end cap module 61 includes a first end cap 611 and a plurality of first buckles 613. The first end cap 611 has a first through hole 612, and the plurality of first buckles 613 are connected to the outside of the first end cap 611, and the plurality of first buckles 613 are arranged at intervals around the first through hole 612. Preferably, the first buckles 613 are integrally connected to the first end cap 611. The first buckles 613 are elastic buckles, and there is a gap between two adjacent first buckles 613 so that the first buckles 613 can deform.

[0087] The inner side of the connecting module body 621 is provided with an annular groove 625, which surrounds the mounting shaft 622 and is arranged coaxially with the mounting shaft 622.

[0088] During assembly, the mounting shaft 622 passes through the first through hole 612 with a clearance fit. The first buckle 613 is engaged in the annular groove 625 to prevent the first end cover 611 from disengaging from the connecting module body 621 along the axial direction. The first buckle 613 can also slide relative to the annular groove 625, so as not to affect the rotation of the first end cover 611 relative to the mounting shaft 622.

[0089] Preferably, the cross-section of the annular groove 625 is L-shaped or T-shaped, and the protrusion of the first buckle 613 is correspondingly L-shaped or T-shaped. The protrusion of the first buckle 613 fits in the annular groove 625 to prevent axial disengagement.

[0090] In one embodiment, as shown in Figures 8-9, the first end cap 611 has an arc-shaped guide groove 614 on the side facing the connecting module body 621. The guide groove 614 surrounds the first through hole 612 and is arranged coaxially with the first through hole 612.

[0091] A positioning piece 626 is provided on the side of the connecting module body 621 facing the first end cover 611, and the positioning piece 626 is fitted in the guide groove 614 with a clearance.

[0092] In this embodiment, the outer surface of the first end cap 611 is also provided with a guide groove 614. The guide groove 614 is arc-shaped with a central angle greater than 180°, preferably around 350°. The guide groove 614 surrounds the first through hole 612 and is arranged coaxially with the first through hole 612.

[0093] A positioning piece 626 is provided on the inner side of the connecting module body 621, and the positioning piece 626 is fitted into the guide groove 614 with a clearance fit. The positioning piece 626 can slide relative to the guide groove 614, thereby limiting the rotation angle of the first end cover 611.

[0094] When the first end cap 611 is rotated, after the two end walls of the guide groove 614 come into contact with the positioning piece 626, the first end cap 611 can no longer be rotated. The rotation angle range of the first end cap 611 is approximately the central angle of the guide groove 614.

[0095] Preferably, the positioning piece 626 is integrally formed with the main body 621 of the connecting module. The positioning piece 626 is arc-shaped and has the same radius of curvature as the guide groove 614 so as to fit the guide groove 614.

[0096] In one embodiment, as shown in Figures 3-5, 7 and 10, the connecting module body 621 is provided with a second buckle 627 on the side facing the first column 1, and the second buckle 627 engages with the wall of the insertion hole 12.

[0097] In this embodiment, a plurality of second buckles 627 are provided on the outer surface of the connecting module body 621 to engage with the hole wall of the insertion hole 12, thereby fixing the connecting module body 621 to the first column 1 and improving the connection stability between the conductive connecting module 62 and the first column 1.

[0098] Preferably, the second buckle 627 is an elastic buckle, which is integrally set with the main body 621 of the connecting module.

[0099] In one embodiment, as shown in FIG10, a plurality of second latches 627 are provided around the plug post 623, and a relief recess 628 is provided at the position of each second latch 627 on the plug post 623, the relief recess 628 providing relief space for the deformation of the second latch 627.

[0100] In one embodiment, as shown in Figures 2-5 and 10-11, the conductive connector 8 includes a connector block 81 and a top cover 82 disposed on the top surface of the connector block 81.

[0101] The plug block 81 has two mounting slots 811 on the side facing the main body 621 of the connection module, and a conductive contact 83 is installed in each mounting slot 811.

[0102] The plug block 81 has a positioning groove 813 on the side opposite to the conductive contact 83. The plug block 81 is detachably inserted into the wiring channel 11. The positioning rib in the wiring channel 11 is inserted into the positioning groove 813. The top cover 82 is located in the top opening of the wiring channel 11.

[0103] In this embodiment, the conductive connector 8 includes a connector block 81, a top cover 82, and two conductive contacts 83. The connector block 81 is block-shaped and is used to insert into the wiring channel 11. The top cover 82 is connected to the top of the connector block 81 and is used to cover the top opening of the wiring channel 11.

[0104] The inner surface of the plug block 81 is provided with two mounting slots 811 spaced apart, and a conductive contact 83 is installed in each mounting slot 811.

[0105] The outer surface of the plug block 81 is provided with a positioning groove 813. The positioning groove 813 is T-shaped and is used to engage with the positioning rib in the wiring channel 11 to install the plug block 81 in the wiring channel 11.

[0106] In one embodiment, as shown in Figures 5 and 11-12, the mounting slot 811 is T-shaped.

[0107] The conductive contact 83 includes a fixing piece 831 installed in the mounting groove 811 and a spring piece 832 located in the slot 812 of the mounting groove 811. The upper end of the spring piece 832 is connected to the fixing piece 831 through a connecting piece 833.

[0108] The fixed piece 831 has extension pieces 834 on both sides extending toward the spring piece 832. The extension pieces 834 are attached to the groove wall of the mounting groove 811 and are interference fit.

[0109] In this embodiment, the mounting groove 811 is T-shaped, and its opening 812 faces the insertion hole 12.

[0110] The conductive contact 83 includes a fixing piece 831, a spring piece 832, a connecting piece 833, and an extension piece 834, which can be connected as a single unit.

[0111] The spring piece 832 is connected to the inner side of the fixed piece 831 via a connecting piece 833. The connecting piece 833 connects the upper ends of the spring piece 832 and the fixed piece 831, forming a roughly U-shaped structure. The extension piece 834 is connected to the side of the fixed piece 831 and extends inward.

[0112] During assembly, the fixing piece 831 and the extension piece 834 are installed in the larger cavity of the mounting groove 811. The extension piece 834 is fitted against the groove wall of the mounting groove 811 with an interference fit to achieve a stable connection.
