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.

[0033] Please also read Figures 1 to 7Now, the multi-lamp splicing device 100 provided in the embodiment of the present application is described. The multi-lamp splicing device 100 is used to splice a plurality of lamp bodies 200 together.

[0034] Please also read Figures 2 to 4 A multi-lamp splicing device 100 includes: a connecting plate 10, a plurality of locking assemblies 20 and a clamping assembly 30, the locking assembly 20 includes a limit block 21, a connecting column 22, a limit column 23 and an elastic member 24, the limit block 21 is installed on the connecting plate 10, the limit block 21 is provided with a through hole 211, the connecting column 22 is movably arranged in the through hole 211, the connecting column 22 has a first end 221 and a second end 222 arranged oppositely, the connecting column 22 maintains a tendency to move from the second end 222 to the first end 221 under the action of the elastic member 24, the limit column 23 is connected to the second end 222, and the clamping assembly 30 is connected to the connecting plate 10.

[0035] The entire locking assembly 20 is fixed to the connecting plate 10 by installing the limit block 21 on the connecting plate 10. There are many ways to install the limit block 21 on the connecting plate 10, for example, the limit block 21 and the connecting plate 10 can be connected by screws, or the limit block 21 and the connecting plate 10 can be clamped or buckled, or the limit block 21 and the connecting plate 10 can be welded, etc., as long as the limit block 21 can be stably installed on the connecting plate 10.

[0036] When multiple lamp bodies 200 are spliced ​​together, each lamp body 200 corresponds to at least one locking assembly 20, and the lamp body 200 and the connecting plate 10 are locked together by the locking assembly 20. When multiple locking assemblies 20 lock multiple lamp bodies 200 and the connecting plate 10 together, the multiple lamp bodies 200 are spliced ​​together.

[0037] Please also read Figure 1 and Figure 5The lamp body 200 has a first side surface 2021 and a second side surface 2022 that are arranged opposite to each other. The lamp body 200 is provided with a locking hole 2023 that penetrates the first side surface 2021 and the second side surface 2022 , and the locking hole 2023 is for the connecting column 22 to pass through. Specifically, when it is necessary to use the locking assembly 20 to lock and fix the connecting plate 10 and the lamp body 200, the multi-lamp splicing device 100 is placed on the first side 2021 of the lamp body 200, and the connecting column 22 is made to correspond to the locking hole 2023 on the lamp body 200, and a force is applied to the connecting column 22 to move the connecting column 22 along the first end 221 toward the second end 222, and the connecting column 22 passes through the locking hole 2023. When the limiting column 23 reaches the second side 2022 and can abut against the second side 2022, the force applied to the connecting column 22 is canceled. Under the action of the elastic member 24, the connecting column 22 moves along the second end 222 toward the first end 221, so that the limiting column 23 abuts against the second side 2022, thereby locking the connecting plate 10 and the lamp body 200. When it is necessary to separate the connecting plate 10 from the lamp body 200, force is applied to the connecting column 22 again to move the connecting column 22 along the first end 221 toward the second end 222, and to disengage the connecting column 22 and the limiting column 23 from the lock hole 2023, thereby separating the connecting plate 10 from the lamp body 200.

[0038] The clamping assembly 30 is used to clamp on the truss to fix the lamp body 200 on the truss. Specifically, after the multi-lamp splicing device 100 splices multiple lamp bodies 200 together to form a lamp, the clamping assembly 30 is clamped on the truss to fix the lamp as a whole on the truss.

[0039] Compared with the prior art, the multi-lamp splicing device 100 provided by the present application is that when multiple lamp bodies 200 need to be spliced, the multi-lamp splicing device 100 is placed on the first side 2021 of the multiple lamp bodies 200, so that each lamp body 200 corresponds to at least one locking assembly 20, and the connecting column 22 is pressed, so that the connecting column 22 drives the limiting column 23 to pass through the locking hole 2023 on the lamp body 200. When the limiting column 23 reaches the second side 2022 and can abut against the second side 2022, the pressing of the connecting column 22 is released, and the connecting column 22 moves along the second end 222 to the first end 221 under the action of the elastic member 24, so that the limiting column 23 abuts against the second side 2022, thereby locking the connecting plate 10 with the lamp body 200. When disassembling, the connecting column 22 is pressed again to change the position of the limiting column 23, so that the connecting column 22 and the limiting column 23 are separated from the locking hole 2023, thereby separating the connecting plate 10 from the lamp body 200. By adopting the multi-lamp splicing device 100 of the present application, with the cooperation of the connecting column 22, the limiting column 23 and the elastic member 24, the locking assembly 20 can quickly lock and separate the connecting plate 10 and the lamp body 200, so that the multiple lamp bodies 200 can be quickly spliced ​​and disassembled, which is beneficial to improve work efficiency and reduce labor intensity. After the multiple lamp bodies 200 are spliced ​​together to form a lamp, the clamping assembly 30 is directly clamped on the truss to quickly fix the entire lamp on the truss, which is convenient for users to operate and saves time and effort.

[0040] Specifically in this embodiment, Figure 2 As shown, the connecting plate 10 is a rectangular plate, and the number of locking assemblies 20 is four, and the four locking assemblies 20 are respectively arranged at the four corners of the connecting plate 10. It can be understood that the multi-lamp splicing device 100 can splice at most four adjacent lamp bodies 200 at the same time, and the four locking assemblies 20 are respectively arranged in a one-to-one correspondence with the four lamp bodies 200, and each locking assembly 20 is used to lock and fix the corresponding lamp body 200 to the connecting plate 10. Of course, when the number of locking assemblies 20 is four, two adjacent lamp bodies 200 or three adjacent lamp bodies 200 can also be spliced ​​at the same time, which has a wide range of applications.

[0041] In other embodiments, the number of locking assemblies 20 can also be other numbers. For example, when splicing two adjacent lamp bodies 200, a multi-lamp splicing device 100 with only two locking assemblies 20 can be selected for splicing. When splicing three adjacent lamp bodies 200, a multi-lamp splicing device 100 with only three locking assemblies 20 can be selected for splicing, which is beneficial to saving costs and reducing space occupancy.

[0042] In one embodiment of the present application, the length extension direction of the limit column 23 is perpendicular or relatively inclined to the length extension direction of the connecting column 22, the locking assembly 20 has an unlocked state and a locked state, and the connecting column 22 can rotate around its own axis relative to the limit block 21, so that the locking assembly 20 switches between the unlocked state and the locked state.

[0043] Optional, such as Figure 3 And such as Figure 4 As shown, the locking hole 2023 is in a strip shape, and the length direction of the locking hole 2023 is slightly larger than the length of the limiting column 23, and the width of the locking hole 2023 is smaller than the length of the limiting column 23, so that on the same plane, when the length extension direction of the limiting column 23 is parallel to the length extension direction of the locking hole 2023, the limiting column 23 can pass through the locking hole 2023, and when the length extension direction of the limiting column 23 is perpendicular to the length extension direction of the locking hole 2023, the limiting column 23 cannot pass through the locking hole 2023. Specifically, when it is necessary to lock and fix the connecting plate 10 and the lamp body 200, align the length extension direction of the limiting column 23 with the length extension direction of the locking hole 2023, press the connecting column 22, and the connecting column 22 drives the limiting column 23 from the first side 2021 through the locking hole 2023 to the second side 2022. At this time, the locking assembly 20 is in an unlocked state; rotate the connecting column 22, and the connecting column 22 drives the limiting column 23 to rotate synchronously until the limiting column 23 can rest on the second side 2022. Release the case on the connecting column 22, and the limiting column 23 rests on the second side 2022. At this time, the locking assembly 20 is in a locked state.

[0044] It can be understood that when the locking assembly 20 is in the unlocked state, the limiting column 23 is at the second side surface 2022, and the length extension direction of the limiting column 23 is parallel to the length extension direction of the lock hole 2023, and the limiting column 23 can be separated from the lamp body 200 from the lock hole 2023; when the locking assembly 20 is in the locked state, the limiting column 23 is at the second side surface 2022, and the limiting column 23 abuts against the second side surface 2022, and the limiting column 23 cannot be separated from the lamp body 200 from the lock hole 2023. By rotating the connecting column 22, the locking assembly 20 is switched between the unlocked state and the locked state.

[0045] The length extension direction of the limiting column 23 can be set perpendicular to the length extension direction of the connecting column 22, or the length extension direction of the limiting column 23 can also be set relatively inclined to the length extension direction of the connecting column 22, as long as the connecting column 22 can be rotated to make the limiting column 23 rest against the second side surface 2022.

[0046] Optionally, the second end 222 is provided with a through hole and a first connecting hole, the through hole extends radially along the connecting column 22, the first connecting hole extends axially along the connecting column 22, and the first connecting hole is connected with the through hole, a second connecting hole is provided on the limiting column 23, the second connecting hole extends radially along the limiting column 23, the limiting column 23 is penetrated in the through hole, the second connecting hole is connected with the first connecting hole, and the fastener passes through the first connecting hole and the second connecting hole to connect the limiting column 23 with the connecting column 22.

[0047] Optionally, the limiting column 23 and the connecting column 22 are integrally formed.

[0048] According to the above technical solution, when the limiting column 23 is located on the second side surface 2022 of the lamp body 200, the limiting column 23 is abutted against the second side surface 2022 or separated from the abutment against the second side surface 2022 by rotating the connecting column 22, so that the locking assembly 20 is switched between the unlocked state and the locked state. The operation is simple and easy to use.

[0049] It should be noted that, in some other embodiments of the present application, the lock hole 2023 includes a interconnected transverse groove and a longitudinal groove, and the length extension direction of the transverse groove is perpendicular to the length extension direction of the longitudinal groove. For example, the transverse groove and the longitudinal groove form a T or L shape, and the length of the transverse groove is greater than the length of the limiting column 23, and the width of the longitudinal groove is less than the length of the limiting column 23. When the connecting column 22 is pressed to make the limiting column 23 reach the second side 2022 from the first side 2021 through the transverse groove, the connecting column 22 is moved to drive the limiting column 23 to move to the position of the longitudinal groove. At this time, since the width of the longitudinal groove is less than the length of the limiting column 23, after the pressure on the connecting column 22 is released, the connecting column 22 moves along the second end 222 toward the first end 221 under the action of the elastic member 24, so that the limiting column 23 abuts against the second side 2022.

[0050] In one embodiment of the present application, see Figure 3 A convex ring 212 is disposed on the inner wall of the through hole 211 , a step surface 223 opposite to the convex ring 212 is formed on the first end 221 , and the elastic member 24 abuts between the convex ring 212 and the step surface 223 .

[0051] Optionally, one end of the elastic member 24 abuts against the convex ring 212 , and the other end of the elastic member 24 abuts against the step surface 223 . The elastic member 24 acts on the step surface 223 to move the connecting column 22 along the second end 222 toward the first end 221 .

[0052] The above technical solution enables at least a portion of the elastic member 24 to be located in the through hole 211 by abutting the elastic member 24 between the convex ring 212 and the step surface 223 , so that the elastic member 24 can more stably push the connecting column 22 to move along the second end 222 toward the first end 221 .

[0053] In this embodiment, the elastic member 24 is a coil spring and is movably sleeved on the connecting post 22 .

[0054] When the connecting column 22 is pressed to move the connecting column 22 along the first end 221 toward the second end 222, the step surface 223 pushes the elastic member 24 to be compressed along the axial direction of the connecting column 22. When the pressure on the connecting column 22 is released, the elastic member 24 rebounds along the axial direction of the connecting column 22 and pushes the connecting column 22 to move along the second end 222 toward the first end 221.

[0055] The above technical solution effectively prevents the elastic member 24 from being radially deformed under the action of external force by movably sleeved the elastic member 24 on the connecting column 22 , thereby improving the stability of the elastic member 24 in axial deformation.

[0056] In other embodiments, the elastic member 24 may also be a spring or other member capable of generating elastic deformation.

[0057] In one embodiment of the present application, please refer to Figure 3 and Figure 4 The limit block 21 is provided with a limit groove 213 extending around the axial center line of the connecting column 22. In the circumferential direction of the connecting column 22, the two opposite ends of the limit groove 213 are spaced apart and not connected, and a limit protrusion 224 inserted into the limit groove 213 is provided on the first end 221.

[0058] Optionally, the limiting groove 213 is communicated with the through hole 211 ; of course, the limiting groove 213 may not be communicated with the through hole 211 .

[0059] Optionally, the limiting groove 213 is in an arc shape, and the angle of the limiting groove 213 is 90°, so that the rotation range of the connecting column 22 is 90°.

[0060] When the connecting column 22 rotates around its own axis, the limiting protrusion 224 moves around the axis of the connecting column 22 in the limiting groove 213. Since the two opposite ends of the limiting groove 213 are not connected, the movement range of the limiting protrusion 224 is limited by the two opposite ends of the limiting groove 213 to limit the rotation range of the limiting protrusion 224, thereby limiting the rotation range of the connecting column 22. In the unlocked state, the limiting protrusion 224 abuts against one end of the limiting groove 213, and in the locked state, the limiting protrusion 224 abuts against the other end of the limiting groove 213.

[0061] The above technical solution, through the cooperation between the limiting protrusion 224 and the limiting groove 213, during the rotation of the connecting column 22, when the locking assembly 20 switches to the locking state, the limiting protrusion 224 abuts against one end of the limiting groove 213, and when the locking assembly 20 switches to the unlocking state, the limiting protrusion 224 abuts against the other end of the limiting groove 213, so that the user can know the state of the locking assembly 20.

[0062] In one embodiment of the present application, the locking assembly 20 further includes a knob 25 , which is located outside the through hole 211 and connected to the first end 221 .

[0063] Optionally, the knob 25 is in an elongated and flat shape.

[0064] The user can twist the knob 25 or press the knob 25 to drive the connecting column 22 to rotate or press down. For example, when the connecting plate 10 needs to be locked and connected with the lamp body 200, the knob 25 is pressed, and the knob 25 drives the connecting column 22 and the limit column 23 to be pressed down. After the limit column 23 passes through the lock hole 2023, the rotation is rotated 90°, and the knob 25 is released. The elastic member 24 pushes the connecting column 22 upward, so that the limit column 23 cooperates with the connecting plate 10 or the limit block 21 to clamp the lamp body 200.

[0065] In the above technical solution, the user can operate the knob 25 to drive the connecting column 22 to rotate or press down, which is convenient for the user to operate.

[0066] In one embodiment of the present application, the locking assembly 20 further includes a limiting ring 26 , which is disposed on the connecting column 22 and between the limiting block 21 and the limiting column 23 .

[0067] Optionally, the limiting ring 26 may be, but is not limited to, a circlip, the limiting ring 26 is clamped on the connecting column 22, and is spaced apart from the limiting column 23 along the axial direction of the connecting column 22. Alternatively, the limiting ring 26 is integrally formed with the connecting column 22, and the limiting ring 26 can abut against the side of the limiting block 21 facing the limiting column 23.

[0068] Since the elastic member 24 can keep the connecting column 22 with a tendency to move in the direction from the second end 222 to the first end 221, when the locking assembly 20 is not in use, the limiting ring 26 abuts against the side of the limiting block 21 facing the limiting column 23, so that the limiting column 23 and the limiting block 21 maintain a preset distance along the axial direction of the connecting column 22. When in use, the movement stroke of the limiting column 23 can be reduced, so that the limiting column 23 can quickly pass through the lock hole 2023.

[0069] In one embodiment of the present application, see Figure 2 The clamping assembly 30 includes a fixing column 31, a clamping seat 32, a clamping cover 33 and a locking rod 34. The fixing column 31 is connected to the connecting plate 10. The clamping seat 32 is arranged on the fixing column 31. The clamping cover 33 is rotatably connected to the clamping seat 32. The locking rod 34 is used to lock the clamping cover 33 and the clamping seat 32.

[0070] Optionally, the bottom end of the fixing column 31 is fixedly connected to the connecting plate 10, for example, the bottom end of the fixing column 31 can be screwed to the connecting plate 10, or the bottom end of the fixing column 31 is welded to the connecting plate 10, or the bottom end of the fixing column 31 is integrally formed with the connecting plate 10. The clamping seat 32 is fixedly connected to the top end of the fixing seat.

[0071] By rotatably connecting the clamping cover 33 and the clamping seat 32, the clamping cover 33 can be rotated relative to the clamping seat 32 to open or close the clamping cover 33, and the clamping cover 33 and the clamping seat 32 are locked by the locking rod 34, so that the clamping assembly 30 can be stably clamped on the truss.

[0072] According to the above technical solution, when the clamping assembly 30 needs to be clamped on the truss, the clamping cover 33 is rotated to open the clamping cover 33, the clamping seat 32 and the clamping cover 33 are placed on opposite sides of the crossbeam of the truss, the clamping cover 33 is rotated in the opposite direction to close the clamping cover 33, and the clamping cover 33 and the clamping seat 32 are locked by the locking rod 34, so that the clamping assembly 30 is stably clamped on the crossbeam of the truss. The operation is simple and convenient for users to use.

[0073] In one embodiment of the present application, the clamping seat 32 has a first connection end 321 and a second connection end 322, the clamping cover 33 has a third connection end 331 and a fourth connection end 332, the third connection end 331 is rotatably connected to the first connection end 321, the fourth connection end 332 is provided with a slot 333, one end of the locking rod 34 is rotatably connected to the second connection end 322, and when the clamping cover 33 is closed, the locking rod 34 can be inserted into the slot 333.

[0074] Specifically, when the clamping assembly 30 needs to be clamped on the truss, the clamping cover 33 is opened, the clamping seat 32 and the clamping cover 33 are placed on opposite sides of the crossbeam of the truss, the clamping cover 33 is closed, and the locking rod 34 is rotated so that the locking rod 34 is inserted into the slot 333 to lock the clamping cover 33 and the clamping seat 32. When the clamping assembly 30 needs to be removed from the truss, the locking rod 34 is rotated in the opposite direction so that the locking rod 34 is disengaged from the slot 333, and the clamping cover 33 is opened to separate the clamping assembly 30 from the truss.

[0075] The above technical solution realizes locking or unlocking the clamping cover 33 and the clamping seat 32 by rotating the locking rod 34 to engage or disengage the locking rod 34 from the locking slot 333. The locking and unlocking actions can be performed quickly and the operation is simple. Moreover, by rotatably connecting one end of the locking rod 34 to the second connecting end 322, the locking rod 34 is not easily lost.

[0076] Of course, in other embodiments, by providing sockets at the second connection end 322 and the fourth connection end 332, when the clamping cover 33 is closed, the locking rod 34 is inserted into the sockets at the second connection end 322 and the fourth connection end 332 to lock the clamping cover 33 and the clamping seat 32.

A plurality of locking assemblies 20 are respectively arranged corresponding to the plurality of mounting holes 13. At least a portion of the limit block 21 is inserted into the corresponding mounting hole 13. The first end 221 and the second end 222 extend out of the first mounting surface 11 and the second mounting surface 12 respectively.

[0078] Specifically, the number of the mounting holes 13 is equal to the number of the locking assemblies 20 , so that each locking assembly 20 can pass through the corresponding mounting hole 13 and extend from the side where the first mounting surface 11 is located to the side where the second mounting surface 12 is located.

[0079] When the multi-lamp splicing device 100 splices multiple lamp bodies 200 together, the second mounting surface 12 faces the first side surface 2021 of the lamp body 200, and the second mounting surface 12 is away from the second side surface 2022 of the lamp body 200, and the part of the limit block 21 extending out of the second mounting surface 12 contacts the first side surface 2021 of the lamp body 200.

[0080] In other embodiments, the limit block 21 may be disposed at the edge of the connecting plate 10 , and the connecting column 22 may directly pass through the through hole 211 so that the first end 221 extends out of the first mounting surface 11 and the second end 222 extends out of the second mounting surface 12 .

[0081] Please also read Figure 1 , Figure 5 , Figure 6 and Figure 7 The embodiment of the present application also provides a lamp, including multiple lamp bodies 200 and a multi-lamp splicing device 100 of any of the above-mentioned embodiments, the lamp body 200 includes a lamp body 201 and an adapter block 202 connected to the lamp body 201, the adapter block 202 has a first side surface 2021 and a second side surface 2022 arranged opposite to each other, the adapter block 202 is provided with a lock hole 2023 that passes through the first side surface 2021 and the second side surface 2022 and is in a strip shape, the limiting column 23 can pass through the lock hole 2023 from the first side surface 2021, and buckle against the second side surface 2022, so as to cooperate with the connecting plate 10 or the limiting block 21 to clamp the adapter block 202.

[0082] Optionally, the cross section of the adapter block 202 is U-shaped and is clamped on the edge of the lamp body 201 , and the adapter block 202 is connected to the lamp body 201 by screws.

[0083] Specifically in this embodiment, the lamp body 201 is rectangular, and the four corners of the lamp body 201 are connected to the adapter blocks 202. By connecting the multi-lamp splicing device 100 to the adapter blocks 202, the four corners of the lamp body 201 can be connected to the adjacent lamp bodies 201 respectively. At the same time, the four corners of the lamp body 201 can be connected to the truss through the multi-lamp splicing device 100.

[0084] It should be noted that the number of the multi-lamp splicing devices 100 of the lamp is determined by the number of the lamp bodies 200. For example, when four lamp bodies 200 need to be spliced ​​together, at least four multi-lamp splicing devices 100 are required. Specifically in this embodiment, the number of lamp bodies 200 is four, the number of multi-lamp splicing devices 100 is nine, and the four corners of the four lamp bodies 200 are connected to the multi-lamp splicing devices 100.
