[0040] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0041] Embodiment 1

[0042] See also Figure 1 The utility model discloses a linkage splicing member 1, referring to Figure 2 The linkage splicing piece 1 includes a splicing seat 10 and a turntable 121; for details, refer to Figure 3The splicing seat 10 is provided with a plurality of splicing units and a connecting position 111 for connecting with an external connecting member 21, wherein the splicing unit includes a first locking component 14, the first locking component 14 is used to approach the connecting position 111 so that the first locking component 14 is in a locked state of locking the connecting position 111, and the first locking component 14 is used to move away from the connecting position 111 so that the first locking component 14 is in an unlocked state of unlocking the connecting position 111; and the first locking component 14 is provided with a first connecting portion, and the first connecting portion is used to drive the first locking component 14 to approach or move away from the connecting position 111 when pressed by an external force.

[0043] See also Figure 4 The turntable 121 is rotatably disposed on the splicing seat 10, the first locking assembly 14 is disposed between the turntable 121 and the splicing seat 10, and a second connecting portion is provided on the turntable 121, wherein the second connecting portion is used to be connected to the first connecting portion in a locked state, and the turntable 121 is used to rotate after the first connecting portion is connected to the second connecting portion, so that the second connecting portion provides a top pressure to drive the first connecting portion to drive the first locking assembly 14 away from the connecting position 111.

[0044] It should be noted that the locking effect of the first locking assembly 14 on the connection position 111 is that the first locking assembly 14 can squeeze or limit the connection member 21 in the connection position 111, and the connection member 21 cannot be separated from the connection position 111. The unlocking effect of the first locking assembly 14 on the connection position 111 is that the first locking assembly 14 and the connection member 21 in the connection position 111 are disconnected, and the connection member 21 can be withdrawn from the connection position 111.

[0045] On the basis of this structure, when using the linkage splicing piece 1 of the utility model, during assembly, the first locking component 14 can be installed on one side of the connecting position 111, and the first locking component 14 can be slidably or movably connected to the splicing seat 10; in addition, a rotating shaft can be set on the splicing seat 10, and a rotating hole can be set in the middle of the turntable 121, the turntable 121 is rotatably connected to the splicing seat 10 through the rotating hole, and the turntable 121 is set above the first locking component 14.

[0046] When splicing the lamp 2, the connecting piece 21 on the lamp 2 can be connected to the connecting position 111 on the splicing seat 10, and then the first locking component 14 is moved close to the connecting position 111 and locks the connecting piece 21 in the connecting position 111, and then the turntable 121 is rotated when the first locking component 14 is in a locked state until the second connecting part is connected to the first connecting part on the first locking component 14. When disassembling the lamp 2, the turntable 121 can be rotated in the unlocking direction, and the second connecting part on the turntable 121 presses the first connecting part, so that the first locking component 14 and the turntable 121 rotate together in the unlocking direction, and the first locking component 14 unlocks the connecting position 111.

[0047] Among them, when there are multiple splicing units, the first connection parts on the multiple first locking components 14 can be connected to the corresponding second connection parts on the rotating disk 121 in the locked state, so when the rotating disk 121 rotates in the unlocking direction, the rotating disk 121 can press the first connection part through the second connection part, and drive all the first locking components 14 to move away from the connecting position 111, so as to achieve simultaneous unlocking. In addition, the first locking component 14 can also be moved away from the connecting position 111 under the action of external force, so when the rotating disk 121 does not rotate, it can be achieved by applying force to the first locking component 14 alone to achieve individual unlocking.

[0048] It should be noted that the connection between the first connection part and the second connection part can be abutting connection or snap connection; specifically, when the first connection part and the second connection part are abutting connection, the first connection part can be an end face of the first locking component 14 along the locking direction, and the second connection part can be an end face of the rotating disk 121 along the unlocking direction, and the first locking component 14 is located in the unlocking direction of the second connection part, so that after the second connection part is abutting connection with the first connection part, the second connection part can push the first connection part to rotate when it moves along the unlocking direction of the first locking component 14, so that the first locking component 14 moves away from the connecting position 111. When the first connection part and the second connection part are snap-fit ​​connection, the first connection part can be set as a snap hole or a snap buckle, and the second connection part can be set as a snap buckle or a snap hole accordingly, and when the snap buckle is snap-fit ​​connection with the snap hole, the rotating disk 121 can drive the first locking component 14 to move away from the connecting position 111 when it rotates along the unlocking direction.

[0049] In this way, by splicing the lamp 2 with the linked splicing piece 1 in this embodiment, firstly, the multiple splicing units on the splicing piece can be used to splice and assemble the multiple lamps 2, so that a suitable light source area can be spliced ​​according to the usage scenario and lighting requirements; secondly, after the lamp 2 is connected to the splicing piece, the splicing piece can lock the connecting piece 21 of the lamp 2 through the first locking component 14, so as to prevent the lamp 2 from being separated from the splicing piece and ensure a reliable connection; finally, when disassembling the lamp 2, all the first locking components 14 can be unlocked at the same time by rotating the turntable 121, or force can be applied to a single first locking component 14 to achieve individual unlocking. The unlocking methods are diverse and easy to operate, and no tools are needed, and the lamp can be disassembled and assembled by hand.

[0050] Further, see Figure 5 , Figure 6 as well as Figure 7 A second locking assembly 125 is provided on the turntable 121, and a locking position 116 is provided on the splicing seat 10; wherein the second locking assembly 125 is used to connect with the locking position 116 in a locked state to prevent the turntable 121 from rotating.

[0051] On the basis of this structure, the second locking assembly 125 includes a turntable lever, and the turntable lever is fixedly connected to the turntable 121; wherein, a locking column 1251 is provided at the bottom of the turntable lever, and the locking column 1251 is connected to the bottom of the turntable lever through a spring. Correspondingly, the locking position 116 is a locking hole or a locking groove on the splicing seat 10. When in use, the turntable lever can be turned to drive the turntable 121 to rotate, and when the turntable 121 rotates, the locking column 1251 is squeezed by the splicing seat 10 and stored in the turntable lever; when the turntable 121 rotates to the locking position 116, the locking column 1251 pops out under the action of the spring and is stuck in the locking hole or the locking groove, thereby realizing the locking state of the second locking assembly 125.

[0052] When the second locking assembly 125 is to be unlocked to allow the turntable 121 to rotate, the button on the turntable lever can be pressed to allow the locking column 1251 to exit the locking position 116, and then the turntable 121 is rotated to drive the first locking assemblies 14 to move away from the connecting position 111.

[0053] Among them, the turntable 121 cannot rotate when the second locking component 125 is in the locked state, which can prevent the second connection part on the turntable 121 from driving the first connection part to rotate, and avoid the turntable 121 from rotating accidentally, causing the first locking component 14 to switch from the locked state to the unlocked state, thereby causing the lamp 2 to separate from the splicing part.

[0054] Further, the first locking assembly 14 includes a locking lever 141, and the first connecting portion is disposed on the locking lever 141, and the locking lever 141 is rotatably connected to the splicing seat 10 through the rotating shaft 15. The locking lever 141 is provided with a limiting portion 142, and the limiting portion 142 is used to limit the connection with the external connecting member 21 after the connecting position 111 is connected to the external connecting member 21. In addition, the splicing unit includes a first elastic member 16, the first elastic member 16 is sleeved on the rotating shaft 15, and the two ends of the first elastic member 16 are respectively connected to the locking lever 141 and the splicing seat 10; wherein the first elastic member 16 is used to provide an elastic stress to drive the locking lever 141 to move close to the connecting position 111, and the locking lever 141 can be used to move away from the connecting position 111 under the action of an external force.

[0055] Based on this structure, the rotating shaft 15 can be fixedly arranged on the locking lever 141, and a rotating hole is arranged on the splicing seat 10, and the rotating shaft 15 can be rotatably arranged in the rotating hole, so that the locking lever 141 can rotate on the splicing seat 10. Among them, the connecting position 111 is arranged on one side of the locking lever 141 along the rotating direction, so that the locking lever 141 can be close to the connecting position 111 when rotating in one direction, and can be away from the connecting position 111 when rotating in the opposite direction. In addition, the limiting portion 142 is arranged on the side of the locking lever 141 facing the connecting position 111, and the shape of the limiting portion 142 is adapted to the outer peripheral shape of the external connecting member 21.

[0056] Specifically, when the outer periphery of the external connector 21 is provided with a groove or a protrusion structure, the limiting portion 142 is correspondingly provided as a protrusion or a groove structure, and the limiting portion 142 is engaged with the connector 21 in the connecting position 111 in a concave-convex manner when the locking lever 141 is close to the connecting position 111. The external connector 21 is installed into the splicing seat 10 along its own axial direction, and the limiting portion 142 is engaged with the connector 21 along the radial direction of the connector 21, so that the limiting portion 142 can limit the axial movement of the connector 21, so that the connector 21 cannot be separated from the connecting position 111.

[0057] Since the locking lever 141 is moved closer to or away from the connection position 111 by rotation, the first elastic member 16 can be set as a torsion spring. During assembly, the torsion spring can be sleeved on the rotating shaft 15, and the fixed end of the torsion spring is connected to the fixed groove 114 on the splicing seat 10, and the movable end of the torsion spring is connected to the locking lever 141.

[0058] Since the torsion spring provides an elastic stress to drive the locking lever 141 to move closer to the connecting position 111, when locking, the locking lever 141 can automatically approach and lock the connecting position 111 under the action of the torsion spring; when unlocking, an external force can be applied to the locking lever 141 or the rotating disk 121 can be used to push the locking lever 141 to overcome the elastic force of the torsion spring and move away from the connecting position 111.

[0059] In this way, after the connecting member 21 of the lamp 2 is connected to the connecting position 111, the first locking assembly 14 can automatically approach and lock the connecting position 111, thereby achieving automatic locking, preventing forgetting, and simplifying the connection operation. When the first connecting portion is pressed by the rotating disk 121, the first connecting portion can drive the locking lever 141 to rotate closer to or farther from the connecting position 111, so that the locking lever 141 and the rotating disk 121 can move synchronously, so that the rotating disk 121 can accurately drive the locking lever 141 to unlock.

[0060] Furthermore, the first connecting portion is a connecting column 147, and the connecting column 147 is fixedly connected to the locking lever 141; Figure 2 as well as Figure 5 The rotating disk 121 is provided with a limiting groove 131. Specifically, the limiting groove 131 extends along the rotation direction of the rotating disk 121, and one end of the limiting groove 131 in the extension direction is provided with a first groove wall 132, and the first groove wall 132 is formed as a second connecting portion. The connecting column 147 is slidably connected in the limiting groove 131, and the connecting column 147 is used to abut against the first groove wall 132 in the locked state.

[0061] Here, it is described by taking the example that the connection position 111 is arranged in the clockwise direction of the locking lever 141 , and the locking direction of the locking lever 141 is the clockwise direction, and the unlocking direction is the counterclockwise direction.

[0062] On the basis of this structure, the groove wall at one end of the limiting groove 131 in the clockwise direction is the first groove wall 132. When locking, the locking lever 141 rotates in the clockwise direction, and the connecting column 147 on the locking lever 141 slides in the clockwise direction in the limiting groove 131. After the locking lever 141 locks the connection position 111, the side of the connecting column 147 abuts against the first groove wall 132 of the limiting groove 131. When unlocking, the rotating disk 121 is rotated in the counterclockwise direction, and the limiting groove 131 pushes the connecting column 147 through the first groove wall 132 to drive the locking lever 141 to rotate in the counterclockwise direction, so that the locking lever 141 is away from and unlocks the connection position 111.

[0063] In addition, when the connection position 111 is set in the counterclockwise direction of the locking lever 141, the locking direction of the locking lever 141 is counterclockwise and the unlocking direction is clockwise; and the groove wall at one end of the limiting groove 131 along the counterclockwise direction is the first groove wall 132.

[0064] In this way, after the first connecting part is connected to the second connecting part, the lock lever 141 can be unlocked by rotating the turntable 121; the first connecting part and the second connecting part are matched with each other in a concave-convex manner and the end faces of the two are abutted for transmission, which can ensure that the turntable 121 accurately drives the lock lever 141 to unlock.

[0065] Further, see Figure 8 A second groove wall 133 is provided at the other end of the limiting groove 131 away from the first groove wall 132, and the second groove wall 133 is used to abut against the connecting column 147 after the second locking assembly 125 is connected to the locking position 116, so that the locking lever 141 remains in a locked state.

[0066] Based on this structure, see Figure 5 When the first locking assembly 14 and the second locking assembly 125 are both in the unlocked state, the locking column 1251 is located between the first groove wall 132 and the second groove wall 133. When locking, an external force can be applied to the locking lever 141 to rotate it clockwise to the locking connection position 111, and then the rotating disk 121 is rotated clockwise to connect the second locking assembly 125 to the locking position 116. Figure 7 After the second locking assembly 125 is locked, the second groove wall 133 abuts against the counterclockwise side of the connecting post 147. In addition, the rotating disk 121 can also be directly rotated clockwise to make the second groove wall 133 approach and push the connecting post 147, and the rotating disk 121 is rotated until the second locking assembly 125 is locked and connected with the locking position 116, and at the same time, the rotating disk 121 drives the locking lever 141 to rotate clockwise and lock the connecting position 111, and at this time, the second groove wall 133 abuts against the counterclockwise side of the connecting post 147.

[0067] At this time, see Figure 7 Since one side of the locking lever 141 along the unlocking direction is restricted by the second groove wall 133 and the rotation of the turntable 121 is restricted, even if the locking lever 141 is accidentally touched, the locking lever 141 can still remain in the locked state.

[0068] When unlocking, the connection between the second locking assembly 125 and the locking position 116 can be released first, and then the turntable 121 is rotated counterclockwise, and the locking column 1251 slides from the second groove wall 133 to the first groove wall 132 in the limiting groove 131. Figure 6After the turntable 121 rotates counterclockwise, the locking column 1251 abuts against the first groove wall 132, and the unlocking direction of the locking column 1251 is not restricted by the second groove wall 133. At this time, the locking lever 141 can be individually moved to unlock a splicing unit, or the turntable 121 can be further rotated counterclockwise, so that the first groove wall 132 can push the locking column 1251, thereby driving all the locking levers 141 to rotate counterclockwise away from the connecting position 111, thereby achieving full unlocking.

[0069] In this way, the double locking effect can prevent the locking lever 141 or the rotating disk 121 from moving away from the connecting position 111 and switching to the unlocked state when the locking lever 141 or the rotating disk 121 is accidentally touched, thereby ensuring the connection reliability in the locked state.

[0070] Furthermore, a limit assembly 124 is provided on the splicing seat 10. Specifically, the limit assembly 124 includes a limit spring column 126 and a fourth elastic member 127. Specifically, the two ends of the fourth elastic member 127 are respectively against the limit spring column 126 and the splicing seat 10, and the limit spring column 126 is used to approach the connection position 111 in the unlocked state to maintain the unlocked state. Among them, a protrusion 128 is also provided on one side of the limit spring column 126, and the protrusion 128 is used to drive the limit spring column 126 away from the connection position 111 when pressed by an external force.

[0071] On the basis of this structure, the fourth elastic member 127 can specifically be a compression spring, and the limiting spring column 126 can automatically move close to the connection position 111 through the fourth elastic member 127; in addition, a receiving groove 123 is also provided on the splicing seat 10, and the receiving groove 123 is arranged opposite to the connection position 111. The receiving groove 123 is used to connect with the external connecting member 21 after the external connecting member 21 is connected to the connection position 111, and the protrusion 128 protrudes from the side wall of the receiving groove 123.

[0072] When in use, an external force can be first applied to the locking lever 141 to move it away from the connecting position 111 so as to be used in an unlocked state, and then the limiting spring column 126 moves close to the connecting position 111 under the elastic stress of the fourth elastic member 127. In this way, when the external force applied to the locking lever 141 is removed, the locking lever 141 automatically approaches the connecting position 111 under the action of the torsion spring and abuts against the limiting spring column 126, thereby preventing the locking lever 141 from locking the connecting position 111 before the connecting member 21 enters the connecting position 111.

[0073] When splicing the lamp 2, the connecting piece 21 on the lamp 2 is first installed into the connecting position 111, and then connected to the receiving groove 123 through the connecting position 111, and the connecting piece 21 presses the protrusion 128 in the receiving groove 123 while entering the receiving groove 123, so that the protrusion 128 drives the limiting spring column 126 away from the connecting position 111, and then the locking lever 141 automatically fastens the connecting piece 21.

[0074] In addition, a pressure plate 129 is provided below the protrusion 128, and the pressure plate 129 is connected to the splicing seat 10; wherein the pressure plate 129 is used to abut against the protrusion 128 when the limiting spring column 126 is close to the connection position 111, thereby limiting the protrusion 128 and the limiting spring column 126 to prevent the protrusion 128 from being separated from the accommodating groove 123.

[0075] In this way, by providing the limiting spring column 126 , the locking lever 141 can be prevented from locking the connection position 111 before the connecting member 21 enters the connection position 111 , so that there is no need to unlock in advance each time the lamp 2 is connected, thereby simplifying the operation.

[0076] Further, see Figure 2 The splicing seat 10 is provided with a connecting groove 112, and the connecting groove 112 includes a guiding section and a locking section 113. Fig. 9 The first locking assembly 14 includes a sliding column 145, a button 143 and a second elastic member 144. In addition, a sliding groove 146 is provided at the bottom of the locking lever 141, and the sliding groove 146 has a first end close to the connecting position 111 and a second end away from the connecting position 111; at the same time, a mounting groove is provided in the locking lever 141, and the two ends of the second elastic member 144 are respectively abutted against the button 143 and the side wall of the mounting groove, and the sliding column 145 is fixedly connected to the button 143.

[0077] See also Figure 3 The sliding column 145 passes through the sliding groove 146 and is slidably connected in the connecting groove 112, wherein the second elastic member 144 is used to provide an elastic stress to drive the button 143 away from the installation groove, and the sliding column 145 is used to slide from the first end to the second end under the action of the elastic stress when sliding into the locking section 113, so as to drive the button 143 to pop out.

[0078] It should be noted that the locking section 113 is arranged at one end of the guide section away from the connection position 111 ; wherein the guide section extends along the circumferential direction of the splicing seat 10 , and the locking section 113 extends along the radial direction of the splicing seat 10 and in a direction away from the splicing seat 10 .

[0079] Based on this structure, the second elastic member 144 can be a compression spring; when unlocking, the sliding column 145 slides away from the connection position 111 to the locking section 113 under the guidance of the guide section. When the sliding column 145 slides in the guide section, the sliding column 145 is limited by the groove wall of the connecting groove 112 along the radial side of the splicing seat 10, so the sliding column 145 is in a state of compressing the second elastic member 144, and the sliding column 145 is located at the first end of the sliding groove 146, and the button 143 is located in the installation groove of the locking lever 141.

[0080] When the sliding column 145 slides into the locking section 113, since the locking section 113 extends along the radial direction of the splicing seat 10 and in the direction away from the splicing seat 10, the sliding column 145 is no longer limited by the groove wall of the connecting groove 112 along the radial side of the splicing seat 10. The sliding column 145 can slide along the first end of the sliding groove 146 to the second end under the action of the elastic stress of the second elastic member 144, and at the same time drive the button 143 to pop out; at this time, the sliding column 145 is pressed and held in the locking section 113 under the action of the second elastic member 144, and is not easy to slide.

[0081] In this way, by providing a locking section 113 at the end of the connecting groove 112 in the unlocking direction, the sliding column 145 can be limited in the locking section 113 when the first locking component 14 is in the unlocking state, so as to prevent the sliding column 145 from sliding freely in the connecting groove 112; and when locking is required, force can be applied to press the button 143 into the installation groove, so that the sliding column 145 can enter the guide section, and the sliding column 145 is guided by the guide section to approach the connecting position 111, so that the locking of the locking lever 141 can be more accurate, and the locking lever 141 can be more stable during the rotation process.

[0082] Furthermore, the splicing seat 10 includes a base 11 and an upper cover 12, and the upper cover 12 is connected to the base 11 by fasteners; wherein the upper cover 12 and the base 11 are spaced apart to form a locking cavity, the splicing unit is arranged in the locking cavity, and the connecting position 111 is arranged through the base 11. The turntable 121 is rotatably connected to the upper cover 12, for details, refer to Figure 8 A plurality of rollers 122 are provided on the upper cover 12, and grooves are provided on the rollers 122, and flanges are provided on the inner circumference of the turntable 121 along the radial direction of the turntable 121, wherein the flanges are embedded in the grooves and rotatably cooperate with the grooves.

[0083] On the basis of this structure, during assembly, the splicing unit can be firstly rotatably connected to the base 11, and then a plurality of rollers 122 are arranged at intervals on the upper cover 12 along the circumferential direction through the rotating shaft, so that the rollers 122 can rotate relative to the upper cover 12, and then the flange on the rotating disk 121 is embedded in the groove of the roller 122, and finally the upper cover 12 is connected to the base 11 through fasteners such as screws or bolts. During use, the rotating disk 121 can be rotated so that the rotating disk 121 rotates relative to the upper cover 12, and the rotating disk 121 drives the locking lever 141 in the splicing unit to rotate during the rotation process.

[0084] In this way, the turntable 121 is rotatably connected to the splicing seat 10 through a plurality of rollers 122 , so that when the turntable 121 rotates, a top pressure can be uniformly applied to each splicing unit, ensuring stable rotation of the turntable 121 and the locking lever 141 .

[0085] In addition, a clamping seat 13 is provided on a side of the upper cover 12 away from the base 11 , and the clamping seat 13 is used to be connected to an external bracket.

[0086] Further, see Figure 4 A third elastic member 134 is provided on the turntable 121, and two ends of the third elastic member 134 are respectively connected to the turntable 121 and the upper cover 12; wherein the third elastic member 134 is used to provide an elastic stress to drive the turntable 121 to rotate, thereby driving the second locking assembly 125 to approach the locking position 116.

[0087] The third elastic member 134 may be a compression spring; specifically, a fixing column is provided on the turntable 121 , and two ends of the third elastic member 134 are fixedly connected to the fixing column and the upper cover 12 , respectively.

[0088] When in use, the turntable lever can drive the turntable 121 to rotate away from the locking position 116 under the action of external force, and the second locking assembly 125 is in an unlocked state; when locking the connection position 111, the locking lever 141 can be locked close to the connection position 111 under the action of external force or the elastic stress of the first elastic member 16. Then, when the external force applied to the turntable lever is removed, the turntable 121 can automatically rotate close to the locking position 116 under the elastic stress of the third elastic member 134, and the second locking assembly 125 is automatically locked.

[0089] In this way, it is possible to prevent the second locking assembly 125 from being missedly locked, thereby causing the connection between the connecting portion 111 and the connecting member 21 to be released when the locking lever 141 is accidentally touched.

[0090] Embodiment 2

[0091] See also Fig.10Different from the first embodiment, the present embodiment discloses a lighting device, which includes a lamp 2 and the linkage splicing piece 1 in the first embodiment; specifically, the lamp 2 is provided with a connecting piece 21, and the connecting piece 21 is provided with a clamping portion 22, wherein the connecting piece 21 is used to connect with the connecting position 111 on the linkage splicing piece 1, and the clamping portion 22 is used to lock and connect with the first locking component 14 after the connecting piece 21 is connected to the connecting position 111.

[0092] Based on this structure, the lamp 2 can be a panel lamp, the connecting part 21 is a support column, and the support column is arranged at the edge of the panel lamp, and the clamping part 22 is a groove arranged on the outer periphery of the support column; the connecting position 111 on the linkage splicing part 1 is a through hole, and the locking lever 141 of the first locking component 14 is provided with a clamping groove.

[0093] During assembly, the support column on the panel light is inserted into the through hole along its own axial direction, the locking lever 141 rotates along the locking direction and approaches the connection position 111, and the clamping groove on the locking lever 141 is clamped into the groove on the support column along the radial direction of the support column, thereby preventing the support column from withdrawing from the through hole along its own axial direction. After the locking lever 141 locks the connection position 111, the first connection portion on the locking lever 141 is connected to the second connection portion on the rotating disk 121.

[0094] When unlocking, the turntable 121 is rotated, and the second connection part on the turntable 121 drives the first connection part to rotate in the unlocking direction, thereby driving the locking lever 141 away from the connection position 111 to achieve unlocking, and the support column can exit the through hole; when the linkage splicing piece 1 is provided with multiple splicing units, and the multiple splicing units are respectively connected to the support columns of multiple panel lights, the turntable 121 can simultaneously drive the locking levers 141 in all the splicing units to unlock, thereby achieving the simultaneous unlocking function. In addition, force can also be applied to the locking lever 141 in one splicing unit to achieve a separate unlocking function.

[0095] In summary, the lighting device in this embodiment can use the linkage splicing piece 1 to splice multiple lamps 2, so that the lighting area can be flexibly set. After the splicing piece is connected to the connecting piece 21 of the lamp 2, the locking lever 141 can automatically lock the connecting piece 21, and the turntable 2 can limit the rotation of the locking lever 141 when the locking lever 141 is in the locked state, so as to keep the locking state of the locking lever 141 from being accidentally released, thereby ensuring reliable connection. In addition, when unlocking is required, the turntable 2 can be rotated to achieve simultaneous unlocking, simplifying the disassembly and assembly operation of the equipment, and no tools are required during the disassembly and assembly process, and it can be operated barehanded.
