Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0029] Please also read Figures 1 to 4 The lamp body joint 100 provided in the embodiment of the present application is now described. The lamp body joint 100 is used to connect the lamp body 200 with the lamp body 200 joint plate, and the lamp body joint 100 includes: a load-bearing column 10, a key lock 20 and an elastic member 30.

[0030] Please also read Figure 2 and Figure 3 A first locking structure 11 is provided at one end of the load-bearing column 10; the button lock 20 is movably connected to the side wall of the load-bearing column 10; the elastic member 30 is provided between the load-bearing column 10 and the button lock 20, and the elastic member 30 is configured to provide an elastic force to the button lock 20 away from the load-bearing column 10 along the radial direction of the load-bearing column 10.

[0031] Among them, one end of the load-bearing column 10 is used to be connected to the lamp body 200, and the other end of the load-bearing column 10 is used to be connected to the splicing plate of the lamp body 200.

[0032] Specifically, see Figure 4The lamp body 200 is provided with a mounting groove 201, a limiting groove 202 and a second clamping structure 203. The limiting groove 202 and the second clamping structure 203 are arranged on the inner wall of the mounting groove 201, wherein the limiting groove 202 runs through the top of the mounting groove 201, and the second clamping structure 203 is arranged near the bottom of the mounting groove 201. One end of the bearing column 10 is inserted into the mounting groove 201. When the key lock 20 and the limiting groove 202 are in a staggered state, the first clamping structure 11 and the second clamping structure 203 are also in a staggered state. The bearing column 10 is rotated. When part of the key lock 20 can be clamped into the limiting groove 202 under the action of the elastic member 30, the first clamping structure 11 and the second clamping structure 203 are mutually clamped. Among them, when the first locking structure 11 and the second locking structure 203 are engaged with each other, the load-bearing column 10 can be limited to move along its own axis, so that the load-bearing column 10 cannot be removed from the installation groove 201. When the button lock 20 is inserted into the limiting groove 202, the load-bearing column 10 can be limited to rotate along its own axis, so that the load-bearing column 10 cannot rotate relative to the lamp body 200.

[0033] Optionally, the first locking structure 11 is a step protruding from the outer wall of the load-bearing column 10, and the second locking structure 203 is a limiting step protruding from the inner wall of the installation groove 201. The mutual engagement between the first locking structure 11 and the second locking structure 203 means that the side of the first locking structure 11 facing the key lock 20 and the side of the second locking structure 203 away from the limiting slot 202 abut against each other, so that the load-bearing column 10 cannot move in the direction from the second locking structure 203 to the limiting slot 202. For example, when the lamp body 200 is in a horizontal state, the load-bearing column 10 cannot move upward relative to the lamp body 200.

[0034] When it is necessary to connect the lamp body joint 100 with the lamp body 200, an external force is applied to the button lock 20 so that the button lock 20 overcomes the elastic force of the elastic member 30 and approaches the center of the load-bearing column 10 along the radial direction of the load-bearing column 10. The elastic member 30 is compressed, and one end of the load-bearing column 10 is inserted into the mounting groove 201 of the lamp body 200 with the button lock 20 and the limiting groove 202 in a misaligned state. The load-bearing column 10 is rotated by a preset angle so that the button lock 20 corresponds to the limiting groove 202 on the lamp body 200, and the elastic member 30 rebounds. Part of the button lock 20 is snapped into the limiting groove 202 of the lamp body 200 under the action of the elastic member 30, and the first snap-in structure 11 and the second snap-in structure 203 are engaged with each other. At this time, the load-bearing column 10 and the lamp body 200 are in a locked state, so that the load-bearing column 10 cannot be removed from the mounting groove 201, nor can it be rotated relative to the lamp body 200. When it is necessary to remove the load-bearing column 10, apply external force to the button lock 20 again until the button lock 20 overcomes the elastic force of the elastic part 30 and disengages from the limiting groove 202, and rotate the load-bearing column 10 again by a preset angle so that the button lock 20 is misaligned with the limiting groove 202 on the lamp body 200, and the first locking structure 11 is misaligned with the second locking structure 203. At this time, the load-bearing column 10 and the lamp body 200 are in an unlocked state, and the load-bearing column 10 can be removed from the mounting groove 201.

[0035] Compared with the prior art, the lamp body splicing joint 100 provided by the present application is as follows: when the lamp body splicing joint 100 of the present application needs to be connected with the lamp body 200, one end of the bearing column 10 is inserted into the installation groove 201 of the lamp body 200, and the bearing column 10 is rotated, so that the key lock 20 is snapped into the limiting groove 202 of the lamp body 200 under the action of the elastic member 30, and the first snapping structure 11 and the second snapping structure 203 of the lamp body 200 are snapped with each other. When it is necessary to separate from the lamp body 200, the key lock 20 is pressed to disengage from the limiting groove 202, and the bearing column 10 is rotated in the opposite direction, so that the key lock 20 and the limiting groove 202 are misaligned. The first locking structure 11 and the second locking structure 203 of the lamp body 200 are offset, and finally the load-bearing column 10 is taken out. The operation is simple, convenient for disassembly and installation, saving time and effort. The first locking structure 11 and the second locking structure 203 of the lamp body 200 are engaged with each other, so that the connection between the lamp body splicing joint 100 and the lamp body 200 is more stable and reliable. Therefore, when the lamp body splicing joint 100 is used to connect multiple lamp bodies 200 with the lamp body 200 splicing plate, the multiple lamp bodies 200 can be quickly spliced ​​together to form a stable and reliable large-area light source, and the multiple lamp bodies 200 can also be quickly separated.

[0036] Specifically in this embodiment, the preset rotation angle of the load-bearing column is 90°. It can be understood that after the load-bearing column 10 is inserted into the installation groove 201, the load-bearing column 10 is rotated 90°, so that the key lock 20 is snapped into the limiting notch 202 of the lamp body 200 under the elastic force of the elastic member 30, and the first snap-in structure 11 and the second snap-in structure 203 of the lamp body 200 are mutually snapped. When the load-bearing column 10 needs to be taken out, the key lock 20 is pressed and the load-bearing column 10 is rotated 90°, so that the load-bearing column 10 can be taken out.

[0037] Please note that Figure 2 A positioning groove 13 is provided at one end of the load-bearing column 10 away from the first locking structure 11, and the load-bearing column 10 can be quickly connected to the splicing plate of the lamp body 200 through the positioning groove 13. For example, after the end of the load-bearing column 10 away from the first locking structure 11 is inserted into the mounting hole of the splicing plate of the lamp body 200, the positioning structure on the splicing plate of the lamp body 200 can be automatically snapped into the positioning groove 13.

[0038] In one embodiment of the present application, see Figure 3 There are two first latching structures 11 , and the two first latching structures 11 are arranged relatively spaced apart along the circumference of the load-bearing column 10 .

[0039] Specifically, the number of the second locking structures 203 is also two, and the two second locking structures 203 are arranged opposite to each other along the circumference of the installation groove 201, and the two first locking structures 11 can respectively engage with the first limit locking structures one by one.

[0040] The above technical solution, by setting two first locking structures 11, after the load-bearing column 10 is inserted into the installation groove 201 and is in place, the load-bearing column 10 is rotated so that the two first locking structures 11 and the two second locking structures 203 are engaged with each other one by one, thereby effectively improving the stability of the connection between the load-bearing column 10 and the lamp body 200.

[0041] In one embodiment of the present application, see Figure 2 and Figure 3 The key lock 20 includes a rotating portion 21, a limiting portion 22 and a pressing portion 23 which are connected in sequence. The rotating portion 21 is rotatably connected to the side wall of the load-bearing column 10, and the elastic member 30 abuts against the limiting portion 22 and / or the pressing portion 23.

[0042] Optionally, the rotating portion 21, the limiting portion 22 and the pressing portion 23 are sequentially arranged along the axial direction of the load-bearing column 10, one end of the elastic member 30 abuts against the side wall of the load-bearing column 10, and the other end of the elastic member 30 abuts against the side of the limiting portion 22 and / or the pressing portion 23. When an external force is applied to the pressing portion 23, for example, when the pressing portion 23 is pressed, the limiting portion 22 and the pressing portion 23 approach the load-bearing column 10 along the radial direction of the load-bearing column 10, and the button lock 20 rotates relative to the load-bearing column 10. When the external force on the pressing portion 23 is withdrawn, the limiting portion 22 and the pressing portion 23 move away from the load-bearing column 10 along the radial direction of the load-bearing column 10 under the elastic force of the elastic member 30, and the button lock 20 rotates in the opposite direction relative to the load-bearing column 10, so that the limiting portion 22 can be stuck in the limiting slot 202.

[0043] The above technical solution, by rotatably connecting the rotating part 21 with the side wall of the load-bearing column 10, the elastic member 30 abuts against the limiting part 22 and / or the pressing part 23, so that when an external force is applied to the pressing part 23, the key lock 20 can overcome the elastic force of the elastic member 30 and rotate relative to the load-bearing column 10. When the external force on the pressing part 23 is removed, the key lock 20 can rotate in the opposite direction relative to the load-bearing column 10 under the elastic action of the elastic member 30, so that the limiting part 22 is automatically stuck in the limiting groove 202 of the lamp body 200. The structure is simple and the operation is convenient.

[0044] In one embodiment of the present application, the rotating portion 21 is disposed along the axial direction of the load-bearing column 10 close to the first locking structure 11 , and the pressing portion 23 is disposed along the axial direction of the load-bearing column 10 away from the first locking structure 11 .

[0045] In a natural state, that is, when no external force is applied to the pressing portion 23, the limiting portion 22 protrudes beyond the load-bearing column 10 relative to the rotating portion 21 under the elastic force of the elastic member 30, so that the side of the key lock 20 away from the elastic member 30 forms a guiding surface inclined toward the direction of the first locking structure 11. In this way, when the load-bearing column 10 is inserted into the mounting groove 201, when the guiding surface contacts the inner wall of the mounting groove 201, it can guide the key lock 20 to rotate, so that the limiting portion 22 and the pressing portion 23 gradually approach the load-bearing column 10.

[0046] The above technical scheme arranges the rotating part 21 along the axial direction of the load-bearing column 10 close to the first locking structure 11, and arranges the pressing part 23 along the axial direction of the load-bearing column 10 away from the first locking structure 11, so that in a natural state, the side of the key lock 20 away from the elastic member 30 is formed with a guiding surface inclined toward the direction of the first locking structure 11, so that in the process of inserting the load-bearing column 10 into the installation groove 201, the key lock 20 is guided to rotate by the guiding surface, so that the limiting part 22 and the pressing part 23 gradually approach the load-bearing column 10, so that when connecting the lamp body splicing joint 100 with the lamp body 200, it is only necessary to apply axial pressing force to the load-bearing column 10, and there is no need to press the key lock 20, which is beneficial to improving the convenience of operation.

[0047] In one embodiment of the present application, please continue to refer to Figure 2 and Figure 3 The side wall of the load-bearing column 10 is provided with a receiving groove 12, the rotating part 21 and the elastic member 30 are both received in the receiving groove 12, and the limiting part 22 can be received in the receiving groove 12 under the action of external force.

[0048] Specifically, the length of the accommodating groove 12 extends along the load-bearing column 10 and is in a strip shape. The length of the accommodating groove 12 is greater than the length of the key lock 20, so that the axial length of the key lock 20 in the load-bearing column 10 can be accommodated in the accommodating groove 12, providing space for the rotation of the limiting part 22 and the pressing part 23.

[0049] Optionally, the rotating portion 21 is located in one end of the receiving groove 12 close to the first locking structure 11 , and one end of the elastic member 30 away from the pressing portion 23 abuts against the inner wall of the receiving groove 12 .

[0050] It should be noted that after the load-bearing column 10 is inserted into the installation slot 201, the pressing portion 23 is located outside the installation slot 201. It can be understood that during the process of inserting the load-bearing column 10 into the installation slot 201, the pressing portion 23 is always located outside the installation slot 201, which is convenient for the operator to press.

[0051] The above technical scheme, by opening a receiving groove 12 on the side wall of the load-bearing column 10, accommodates the rotating part 21 and the elastic part 30 in the receiving groove 12, so that the overall structure of the lamp body splicing joint 100 is compact, which is beneficial to reducing the volume of the lamp body splicing joint 100 and reducing the space occupied. The limiting part 22 can be accommodated in the receiving groove 12 under the action of external force, and the outer periphery of the load-bearing column 10 can be set to a size compatible with the installation groove 201, so that when the load-bearing column 10 is inserted into the installation groove 201, the outer wall of the load-bearing column 10 fits with the inner wall of the installation groove 201, effectively preventing the load-bearing column 10 from shaking and improving the stability of the load-bearing column 10 inserted in the installation groove 201.

[0052] In one embodiment of the present application, the lamp body joint 100 further includes a rotating shaft 40 , which is radially disposed through the load-bearing column 10 and the rotating portion 21 to enable the rotating portion 21 to be rotatably connected to the load-bearing column 10 .

[0053] Specifically, a first axial hole is provided on the side wall of the load-bearing column 10, the axial direction of the first axial hole is perpendicular to the axial direction of the load-bearing column 10, and is connected to the accommodating groove 12. A second axial hole is provided on the rotating part 21, and the second axial hole is correspondingly connected to the first axial hole. The rotating shaft 40 is rotatably connected to the load-bearing column 10 by penetrating the first axial hole and the second axial hole, that is, the key lock 20 can rotate around the rotating shaft 40 relative to the load-bearing column 10.

[0054] Furthermore, an avoidance groove 14 is provided on the side wall of the load-bearing column 10 . The avoidance groove 14 is communicated with the first shaft hole, and the avoidance groove 14 is used to avoid the rotating shaft 40 .

[0055] The above technical solution, through the shaft 40 passing through the load-bearing column 10 and the rotating part 21, makes the rotating part 21 rotatably connected with the load-bearing column 10, which is beneficial to improve the stability of the connection between the rotating part 21 and the load-bearing column 10, making it difficult for the rotating part 21 to escape from the receiving groove 12.

[0056] It should be noted that, in other embodiments, a protrusion may be provided on the side wall of the receiving groove 12, a concave hole may be provided on the load-bearing column 10, and the protrusion may be inserted into the concave hole to realize the rotational connection between the rotating part 21 and the load-bearing column 10. Alternatively, a concave hole may be provided on the side wall of the receiving groove 12, a protrusion may be provided on the load-bearing column 10, and the protrusion may be inserted into the concave hole to realize the rotational connection between the rotating part 21 and the load-bearing column 10.

[0057] In one embodiment of the present application, an anti-slip pattern 26 is provided on the side of the key lock 20 facing away from the elastic member 30 .

[0058] Specifically, the anti-slip pattern 26 is disposed on the side of the pressing portion 23 facing away from the elastic member 30 .

[0059] The above technical solution has a good anti-slip effect by providing the anti-slip groove 26 on the side of the key lock away from the elastic member 30. When the operator presses the key lock 20, relative sliding is not likely to occur.

[0060] In one embodiment of the present application, see Figure 3 A limiting boss 15 is provided on the inner wall of the accommodating groove 12, and the limiting boss 15 has a first contact surface 151 and a second contact surface 152 which are arranged opposite to each other. Part of the elastic member 30 abuts against the first contact surface 151, and the key lock 20 also includes a hook portion 25 connected to the rotating portion 21, and the hook portion 25 can abut against the second contact surface 152.

[0061] Optionally, the limiting boss 15 and the load-bearing column 10 are integrally formed.

[0062] When the load-bearing column 10 is in a vertical state, the first contact surface 151 and the second contact surface 152 are respectively the upper surface and the lower surface of the limiting boss 15 .

[0063] The hook portion 25 protrudes out of the side of the rotating portion 21 toward the elastic member 30 . The elastic member 30 and the hook portion 25 are respectively located on opposite sides of the limiting boss 15 along the axial direction of the load-bearing column 10 .

[0064] The above technical solution effectively ensures the stability of the elastic member 30 in the accommodating groove 12 by partially abutting the first contact surface 151 of the elastic member 30. In the natural state, the hook 25 abuts against the second contact surface 152 to limit the extreme position of the key lock 20 to rotate outward.

[0065] In one embodiment of the present application, the key lock 20 further includes a stopper 24 , which is disposed at one end of the pressing portion 23 away from the rotating portion 21 and protrudes from the side of the pressing portion 23 toward the elastic member 30 .

[0066] Optionally, the rotating portion 21 , the limiting portion 22 , the pressing portion 23 , the blocking portion 24 and the hook portion 25 are integrally formed.

[0067] The stopper 24 and the limiting boss 15 are spaced apart from each other along the axial direction of the load-bearing column 10 , and the elastic member 30 is disposed between the stopper 24 and the limiting boss 15 along the axial direction of the load-bearing column 10 .

[0068] Optionally, the elastic member 30 is a spring sheet, and the spring sheet is substantially V-shaped or U-shaped, and the middle portion of the spring sheet abuts against the first contact surface 151 .

[0069] Of course, in other embodiments, the elastic member 30 may also be a spring or other elastic components.

[0070] Please also read Figure 1 and Figure 4 The embodiment of the present application also provides a lighting device, including: a lamp body 200 and a lamp body joint 100 of any of the above embodiments, the lamp body 200 is provided with an installation groove 201, a limiting groove 202 and a second clamping structure 203, one end of the load-bearing column 10 is inserted into the installation groove 201, and the button lock 20 is clamped into the limiting groove 202 under the elastic force of the elastic member 30, and the first clamping structure 11 and the second clamping structure 203 are engaged with each other.

[0071] Specifically in the embodiment, the lamp body 200 is a panel lamp.

[0072] Optionally, there are two limit slots 202, which are relatively arranged along the circumference of the installation slot 201, and there is one button lock 20. In this way, after the load-bearing column 10 is inserted into the installation slot 201, the button lock 20 can be inserted into any limit slot 202 by rotating the load-bearing column 10 counterclockwise or clockwise by a preset angle.
