Description

Technical Field

[0001] This invention relates to the field of lighting technology, and more particularly to a splicing device and its stage light. Background Technology

[0002] Stage lighting systems are a core component of modern performing arts, large-scale events, and architectural landscape lighting. With the development of stage art and technology, matrix lighting installations formed by combining multiple lamps are widely used in concerts, theaters, and film shoots due to their strong dynamic expression and wide visual coverage. Traditional single lamps can no longer meet the complex lighting effect design requirements, and modular, spliced ​​stage lighting is gradually becoming an industry trend.

[0003] Currently, common stage lighting splicing structures mainly rely on the following technical solutions, but they still have significant shortcomings:

[0004] Bolted splicing, which uses flanges and bolts for mechanical connection, is structurally stable, but requires special tools for disassembly and assembly, resulting in low efficiency for on-site adjustments, and frequent disassembly can easily lead to thread wear.

[0005] The magnetic docking structure uses magnetic components to achieve rapid splicing, but the magnetic field is easily interfered with by external electronic devices, and there is a risk of overheating and demagnetization when high-power lamps are running, resulting in insufficient reliability.

[0006] To address the aforementioned issues, there is an urgent need to develop a stage lighting splicing structure that supports rapid assembly and disassembly and has strong compatibility, in order to improve the reconfigurability and operation and maintenance efficiency of the lighting system, while reducing the deployment cost of large lighting installations. Summary of the Invention

[0007] To solve one of the above-mentioned technical problems, this invention provides a splicing device that is quick to assemble and disassemble, highly expandable, structurally stable, compatible, and modularly designed. It also provides a stage lamp that uses this splicing device.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0009] A splicing device includes a splicing base with an inner cavity. The left and right outer sides of the splicing base are recessed to form inserts on the upper and lower sides. One insert of the splicing base is used to insert into a slot of a lamp body, and the other insert of the splicing base is used to insert into a slot of another lamp body, so that two adjacent lamp bodies can be connected together by the splicing base. At least two elastic buckles are movably disposed in the inner cavity of the splicing base. Each elastic buckle has a locking protrusion on its outer side for engaging with a slot of a lamp body. The elastic buckle prevents the insert of the splicing base from disengaging from the slot by engaging the locking protrusion with the slot. When the locking protrusion of the elastic buckle disengages from the slot, the insert of the splicing base can be disengaged from the slot.

[0010] Further defined, the splicing base has at least one through-hole communicating with the inner cavity, the notch corresponds to the elastic buckle, and the elastic buckle can abut against the edge of the notch during the movement, thereby limiting the extreme position of the elastic buckle's movement. When the elastic buckle is active, the locking protrusion can extend from the inner cavity to the outside of the notch, at which time the locking protrusion engages with the locking groove; when the elastic buckle is active, the locking protrusion can also retract from the outside of the notch back to the inner cavity, at which time the locking protrusion disengages from the locking groove.

[0011] Further defined, the thickness of the insert gradually increases from the front end to the rear end of the splicing base.

[0012] Further defined, a hinge block is fixedly connected inside the inner cavity, and the two sides of the hinge block are respectively hinged to the elastic buckle through hinge shafts, so that the elastic buckle can rotate relative to the splicing seat.

[0013] Further defined, a spring is provided between the two elastic buckles to act on the protruding retainer extending out of the notch.

[0014] Further defined, the buckle protrusion includes an inclined portion, the height of which gradually increases from the front end to the rear end of the elastic buckle.

[0015] Further defined, the card protrusion also includes a longitudinal portion for abutting against the card slot.

[0016] Further defined, the end of the elastic buckle is provided with a pressing part, the inner cavity has an opening, and a stop block is provided opposite to the edge of the opening, located between the two pressing parts. When the elastic buckle is pressed and closed by the pressing part, the pressing part can abut against the stop block.

[0017] Further specified, the splicing base has drainage holes on its left and right sides that communicate with the inner cavity.

[0018] A stage light includes multiple light bodies and the splicing device, wherein two adjacent light bodies are spliced ​​together by the splicing device.

[0019] By adopting the above technical solution, the present invention has at least the following beneficial effects:

[0020] During assembly, the splicing base connects to adjacent splicing base slots via inserts on both sides, connecting adjacent light fixtures together. The direction in which the inserts are inserted into or removed from the slots is called the insertion / removal direction. The splicing base restricts or allows movement in the insertion / removal direction through the engagement of latches and slots, thus completing the splicing, fixing, or disassembling of the stage lights. Compared to existing technologies, this splicing device enables stage lights to have the functions of rapid assembly and disassembly, efficient expansion, and strong structural stability. It also features compatibility and modular design, facilitating mass production and replacement of damaged parts, reducing maintenance complexity. Attached Figure Description

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] As attached Figure 1 To be continued Figure 3As shown, a splicing device includes a splicing base 1 with an inner cavity 10. The left and right outer sides of the splicing base 1 are recessed to form inserts 11 on the upper and lower sides. One insert 11 of the splicing base 1 is used to insert into a slot 21 of a lamp body 2, and the other insert 11 of the splicing base 1 is used to insert into a slot 21 of another lamp body 2. At least two elastic buckles 12 are movably disposed in the inner cavity 10 of the splicing base 1. The outer side of each elastic buckle 12 is provided with a protrusion 121 for engaging with a slot 22 of the lamp body 2. The slot 22 is opened in the slot 21. The elastic buckle 12 engages with the slot 22 through the protrusion 121 to prevent the insert 11 of the splicing base 1 from disengaging from the slot 21. When the protrusion 121 of the elastic buckle 12 disengages from the slot 22, the insert 11 of the splicing base 1 can be disengaged from the slot 21. During assembly, the splicing base 1 connects to the slots 21 of two adjacent splicing bases 1 respectively through the inserts 11 on both sides, so that the two adjacent lamp bodies 2 are connected together through the splicing base 1. To further explain, the direction in which the inserts 11 are inserted into the slots 21 or the direction in which the inserts 11 are pulled out of the slots 21 can be called the insertion and removal direction. The splicing base 1 restricts or allows its movement in the insertion and removal direction by the cooperation of the latch 121 and the slot 22, thereby completing the splicing, fixing or disassembling of the stage lamp. Compared with the prior art, this splicing device enables the stage lamp to have the functions of quick assembly and disassembly, efficient expansion and strong structural stability. At the same time, it has compatibility and modular design, which facilitates mass manufacturing and replacement of damaged parts, and reduces maintenance complexity.

[0029] Further explanation is provided in the appendix. Figure 4 As shown, the slot 21 includes a first slot 211 and a second slot 212 arranged radially from the inside to the outside of the lamp body 2. The first slot 211 and the second slot 212 are interconnected, and the width of the opening 102 of the first slot 211 is greater than the width of the opening 102 of the second slot 212. The splicing base 1 has a recess 110 between the upper and lower inserts 11 on both the left and right sides. The inserts 11 are adapted to the first slot 211, and the recess 110 is adapted to the opening 102 of the second slot 212.

[0030] In this embodiment, the splicing base 1 has at least one notch 101 communicating with the inner cavity 10. The notch 101 corresponds to the elastic buckle 12. During the movement of the elastic buckle 12, it can abut against the edge of the notch 101, thereby limiting the extreme position of the elastic buckle 12. The elastic buckle 12 has a first extreme position and a second extreme position. The position where the elastic buckle 12 abuts against the edge of the notch 101 is the second extreme position. When the elastic buckle 12 moves from the first extreme position to the second extreme position, the locking protrusion 121 can extend from the inner cavity 10 to the outside of the notch 101. At this time, the locking protrusion 121 engages with the locking groove 22. When the elastic buckle 12 moves from the second extreme position to the first extreme position, the locking protrusion 121 can also retract from the outside of the notch 101 back to the inner cavity 10. At this time, the locking protrusion 121 disengages from the locking groove 22.

[0031] In this embodiment, the end of the elastic buckle 12 is provided with a pressing part 124 for manual operation. The inner cavity 10 has an opening 102. At the edge of the opening 102, a stop block 13 is provided between the two pressing parts 124. When the elastic buckle 12 is pressed and closed by the pressing part 124, the pressing part 124 can abut against the stop block 13. Specifically, when the pressing part 124 and the stop block abut against each other, the elastic buckle 12 is at the first limit position, that is, the elastic buckle 12 retracts to the limit position of the inner cavity 10, and the stop block 13 effectively prevents the elastic buckle 12 from being over-compressed.

[0032] In this embodiment, the thickness of the insert 11 gradually increases from the front end to the rear end of the splicing base 1. In other words, the front end of the insert 11 is relatively thin and the rear end of the insert 11 is relatively thick, which makes it easier for the insert 11 to be inserted into the slot 21 from the front end, thereby improving assembly efficiency and installation stability.

[0033] As attached Figure 3 As shown, a hinge block 3 is fixedly connected inside the inner cavity 10. Both sides of the hinge block 3 are hinged to elastic buckles 12 via hinge shafts 31, allowing the elastic buckles 12 to rotate relative to the splicing base 1. A spring 4 is provided between the two elastic buckles 12, acting on the latch protrusion 121 to keep it protruding from the notch 101, giving the elastic buckles 12 a certain degree of elasticity. The elastic buckles 12 can automatically reset after being pressed. Furthermore, the elastic buckles 12 have limiting grooves. One end of the spring 4 is housed in the limiting groove of one elastic buckle 12, and the other end is housed in the limiting groove of the other elastic buckle 12, increasing the installation stability of the spring 4.

[0034] As attached Figure 2 and attached Figure 3As shown, the latching protrusion 121 includes an inclined portion 122, the height of which gradually increases from the front end to the rear end of the elastic buckle 12. During the insertion of the insert block 11 of the splicing base 1 into the slot 21, the inclined portion 122 can abut against the side wall of the slot 21, and the elastic buckle 12 is gradually compressed until the latching protrusion 121 reaches the position of the slot 22. Under the action of the spring 4, the latching protrusion 121 automatically engages in the slot 22, thereby completing the locking after engagement.

[0035] In this embodiment, the protrusion 121 further includes a longitudinal portion 123 for abutting against the slot 22. Specifically, the longitudinal portion 123 is perpendicular to the insertion direction, so that after the protrusion 121 is inserted into the slot 22, the longitudinal portion 123 can abut against the side wall of the slot 22. Preferably, we can also selectively provide a colored warning line on the longitudinal portion 123 for observing whether the longitudinal portion 123 is in place.

[0036] The splicing base 1 has drainage holes 14 on its left and right sides that communicate with the inner cavity 10, so that the inner cavity 10 communicates with the slot 21 through the drainage holes 14, preventing water from accumulating in the slot 21 or the inner cavity 10.

[0037] As attached Figure 4 and attached Figure 5 As shown, the present invention also provides a stage lamp in which two adjacent lamp bodies 2 can be spliced ​​together by the splicing device 100 described above.
